8 Claims.

This invention relates to marking machines adapted to make the same impression repeatedly on a strip of web material as it is fed forward. Machines of this type are commonly used for printing a series of tags connected together in a strip.

One feature of the present invention relates to a novel means for feeding the strip or web as the printed impressions are made by which the extent of feeding movement for each printed impression can be varied thereby adapting the machine for printing tags of different sizes.

Another feature of the invention relates to means for scoring or perforating the web or sheet transversely at the places which constitute the division line between successive tags so that the tags can be readily separated from each other after they have been printed.

Other features of the invention relate to improvements in the printing head by which the type may be readily changed for making different printed impressions.

Still other features of the invention relate to various improvements in printing machines of this type which will be more fully hereinafter set forth.

The machine is provided with the usual work support over which the strip is fed and which constitutes one element of the printing couple, means to feed the strip over the work support with a step by step movement, a printing head carrying type members which is movable toward and from the work support and which constitutes the other element of the printing couple and an inking pad with which the type of the printing head are brought into engagement between each printed impression forthe purpose of inking the type.

These elements and the operating mechanism therefor are carried by a suitable frame indicated generally at 1 and which is herein shown as mounted on a table or stand 2.

The strip or web on which the series of printed impressions are to be made is indicated generally at 3. The work support over which this strip is fed and which constitutes one element of the printing couple is indicated at 4. The printing head carrying the type members is indicated generally at 5 and the inking pad by which the type is inked is indicated at 6.

The work support is in the form of a table which is herein shown as yieldingly mounted. The table is provided with a stem 7 which extends through a suitable bearing member 8 with which the frame 1 is provided, the lower end of the stem being supported by a spring 9 which is carried by a yoke 10 that is secured to the frame by suitable suspender rods 11. The tension of the spring 9 may be adjusted by advancing or retracting the nuts 12 which are screw threaded to the suspender rods 11.

The printing head 5 comprises a suitable frame 13 by which the type elements are supported and which is mounted on parallel crank arms 14, 15 that are rigid with two parallel shafts 16, 17 that are journalled in the frame 1. These shafts are oscillated by a mechanism presently to be described and the oscillating movement carries the printing head through an arc to bring the type characters into engagement alternately with the printing pad 6 and the work supported on the work support, as indicated by the dotted line positions in Fig. 1. The frame 13 is maintained in an upright position during its movement because of the parallel ruler action of the parallel crank arms 14, 15.

For giving these shafts 16, 17 their oscillating movement by which the printing head derives its movement from one dotted line position to the other in Fig. 1, each shaft is provided with a gear 18 which meshes with a vertically-moving rack 19' that is suitably guided by the frame 1. This rack is given its vertical movement through the medium of a cam on a cam shaft 20 that is journalled in the frame 1. As herein shown the lower end of the rack bar 16 is formed with a slot 21 which embraces the shaft 20 and said bar is provided with a projection or follower 22 which operates in a cam groove 23 formed in a cam member 24 that is fast on the cam shaft 20. At each rotation of the cam shaft 20 the rack loo 19 will be given a complete reciprocation including an up and down movement and the printing head will make a complete excursion during which it will be brought into engagement with the inking pad and then be carried into printing position and subsequently returned to initial position.

The shaft 20 may be operated in any suitable or usual way. As herein shown we have provided a motor for furnishing the power and will provide some suitable reducing gearing, such as worm gearing between the motor shaft 26 and the cam shaft 20. Since this reducing gear-- ing may be of any appropriate or usual kind we have not illustrated it in detail herein.

We will also preferably. employ a clutch at some specific point between the motor and the cam shaft 20 so that by disengaging the clutch the operation of the cam shaft may be terminated without stopping the motor. Any usual form of one-revolution clutch may be employed for this purpose and as one-revolution clutches are commonly employed in machines of this type We have not thought it necessary to illustrate such a clutch herein.

The clutch may be controlled in usual manner by a suitable treadle 27 which is connected to the clutch control mechanism through a rod connection 28 and as usual in devices of this sort the clutch will preferably be so designed that it will be started in operation by actuation of the treadle 27 and will continue in operation so long as the treadle remains depressed but will stop at predetermined point in the revolution of the shaft 20 when the treadle is released.

Themeans for intermittently feeding the strip 3 is also actuated from the cam shaft 20. This strip may be taken from any source but may conveniently be drawn from a reel 29 which is supported by the stand 2. The feeding movement of the strip is given to it through the medium of a feed roll 30 over which the strip passes and a co -operating presser roll 31 which rests on the upper face of the strip. The feed roll 30 may be of rubber or any other suitable material which will provide a proper friction surface and it is shown as fast on a shaft 32.

This shaft carries a ratchet wheel 33 with which co-operates a plurality of spring-pressed pawls 34 that are mounted on a pawl carrier 35 that is situated axially of the shaft 20 and is journalled in the frame. This pawl carrier has a gear 36 rigid therewith which meshes with a-reciprocating rack 37. The rack is given a reciprocating movement from the cam shaft 20 and because of the pawl and ratchet connection between the gear 36 and the shaft 20 it will be understood that the movement of the rack 37 in one direction will give forward rotative movement to the feed roll 30 while during the movement of the rack in the opposite direction the pawls will merely click over the teeth of the ratchet while the feed roll 30 remains stationary.

The rack member 37 reciprocates in a suitable guide 140 and is connected to a crank arm 38 which is fast on a shaft 39 journalled in suitable bearings 40 carried by the frame. This shaft 39 has another arm 41 fast thereto to which is connected one end of a link 42, the other end of which is provided with an elongated loop portion 43 which embraces and is guided by a collar or hub 44 fast on the cam shaft 20. This link 42 is provided with a projection or follower 45 which operates in a cam groove 46 carried by a cam member 47 that is fast on the cam shaft 20. Hence during each rotation of the cam shaft 20 the shaft 39 will be given one complete oscillation and the rack bar 37 will also be given one complete reciprocation. The strip 3 will thus be given one forward step during each rotation of the shaft 20.

Means are provided for varying the length of the forward step thus given to the strip 3 for each rotation of the cam shaft 20. One construction by which this adjustment may be made is that of providing an adjustable connection between the link 42 and the arm 41. As shown the arm 41 is slotted and the link 42 is connected thereto through the medium of a bolt 48 which is adjustable in the slot.

The throw of the cam groove 46 is constant and by adjusting the connection 43 between the link 42 and the arm 41 outwardly away from the shaft 39, the amplitude of oscillation of said shaft will be decreased and the length of the feeding movement of the feed roll 30 will be correspondingly decreased while an adjustment in the opposite direction will cause an increase in the feeding movement.

We have also shown an adjustable connection between the rack bar 37 and the arm 38 by which the feeding movement may be adjusted, such adjustable connection being specially adapted for giving a fine adjustmen As illustrated in Figs. 1 and 2 the rack bar 37 is pivotally connected at one end to a block 49 which operates in a slot 50 formed in the crank arm 38 and this block has screw-threaded engagement with an adjusting screw 51 which extends longitudinally of the arm 38. By turning the adjusting screw 51 the block 49 can be adjusted toward and from the centerof oscillation thereby correspondingly varying the amplitude of movement of the rack bar 37 relative to the oscillatory movement of the shaft 39.

The adjustment between the link 42 and the arm 41 provides means for quickly obtaining an approximate adjustment of the feeding means. The adjusting screw 51 provides means for getting a much finer adjustment because with this adjusting screw the block 49 can be easily adjusted small amounts.

For obtaining very fine adjustments of the feeding movement of the strip we have provided additional adjusting means shown in Fig. 10. The feed roll 30 is made slightly conical and means are provided for adjusting said roll in the direction of its axis so as to bring the portion of larger or smaller diameter in position to feed the strip depending on whether it is desired to increase slightly or decrease slightly the feeding movement. This roll is splined to the shaft 32 so that it must rotate therewith but can slide longitudinally thereof. The roll is held confined b tween the arms of a yoke member 52 which is slidable on the shaft 32 and which can be adjusted in the direction of the axis of the roll through the medium of an adjusting screw 53. This screw is mounted in suitable hearings in the frame 1 and screw threads through an extension 54 with which the yoke 52 is provided. The end of the screw is provided with a handle 55 by which it may be turned.

By turning the adjusting screw 53 so as to move the feed roll 30 to the right Fig. 10 the portion of larger diameter will be brought underneath the strip 3 and the strip will thus have a slightly increased feeding movement during each forward step of the roll. On the other hand, if the roll is adjusted to the left Fig. 10'

the portion of smaller diameter will be brought into engagement with the strip 3 and the forward movement which the strip is given will be slightly less than before the adjustment was made.

There is thus provided not only the means for securing a coarse adjustment of the feeding means by the adjustment of the link 42 relative to the arm 41, but there is also the adjusting means in connection with the arm 38 for making a fine adjustment and the mechanism in connection with the feed roll for making a still finer adjustment.

The presser roll 31 is yieldingly held against the strip and thus yieldingly holds the strip against the feed roll 30. This presser roll is rotatively mounted on a rod 56 which connects to two blocks 57. These blocks are secured to the upper ends of rods 58 which are vertically movable in suitable bearings 59 carried by the frame and which are acted upon by springs 60 which normally apply a downward pressure on the rods 58. The springs 60 are confined between the guiding ears or projections 59 and nuts 61 that are screw threaded 1 to the rods 60, the adjustment of the nuts providing for adjusting the tension of the springs 60.

We have provided herein means for raising the presser roll 31 whenever it is desired to introduce the end of a fresh strip into position or make any manual adjustment of the strip.

The lower ends of the rods 58 rest on the eccentric portions 62 of a rod 63 which is mounted for turning movement in hangers 64 so that by turning said rod the eccentric portions act as cams against the lower ends of the rods 58 to raise the latter. This rod 63 is provided with an arm 65 by which it may be turned.

The printing head herein shown is provided with a type chase carrying interchangeable or adjustable type characters and said type chase is of that type in which the type characters may be introduced thereinto from the upper side. In the construction shown in Figs. 1 to 6 the type chase is arranged to carry individual type mem- I bers and is constructed somewhat similar to the type chase or printing head shown in Patent No. 1,687,951, dated October 16, 1928. The type chase comprises a skeleton frame member 66 which is provided with a plurality of pairs of type '1 supporting bars 6'? extending transversely across the frame, each pair of bars forming a slot between them into which the individual type members 68 may be inserted from the upper side of the frame. These type members are provided j with shoulders 69 adapted to rest on the bars.

The type chase 66 is carried in a frame 160 which in turn is pivotally connected at 71 to the sides of the movable head 13.

The type characters are retained in position by a backing plate '70 which, when in operative position, overlies the upper ends of the type members 68 and retains them firmly in position while the printed impression is being made.

The backing plate is movably carried by the .1 printing head so that it can be moved either into operative position wherein it forms a backing for the type characters or out of operative position as shown in Fig. 4 in which it is removed from engagement with the type characters so that they can be readily removed from the frame 66. The inoperative position of the backing plate '70 shown in Fig. 4 is also the position which the plate occupies while type characters are being inserted into the frame 66.

We have provided herein a simple means for giving the backing plate '70 its movement from operative to inoperative position and said means have the further function of tipping the frame 160 into the angular position shown in Fig. 4 so as to make it easier to remove the type characters from the frame or to insert new characters therein. The skeleton frame 160, which is pivoted to the movable head 13 at its rear edge as shown at 71, has at each side an upstanding flange or wall '72 which is provided with a slot 73, said walls '72 being situated just inside of the two side walls of the frame 13.

The backing plate 70 is provided at each side near its front edge with a roll or projection 74 which extends through the slot 73 in the corresponding wall '72 and which also extends into a groove 75 formed in the inner face of the cheek pieces 76 of the frame 13. The backing plate 70 is secured to the lower end of a lever '77 which is pivoted to the frame 13 at 78 and said lever extends above the frame and is provided with a handle '79 by which it may be manipulated.

Fig. 4 shows the backing plate 76 in its inoperative position with the type characters 68 uncovered and accessible for removal from the type chase 66 through the top. If the handle '79 is swung to the right Fig. 4 about its pivot '18 such movement will swing the backing plate to the left and during this movement the rolls 74 at the front of said plate will move along the slots '73 and along the groove 75. During such movement these projections 74 will act on the upper edge of the slots 73 thereby to swing the frame 160 upwardly about its pivot '71 into a horizontal position shown in Fig. 12. The frame 160 will thus be locked in its operative position and the backing plate 70 will also be locked to the frame 13 thereby forming a solid backing for the type characters 68.

A swinging movement of the handle from its normal vertical position into the position shown in Fig. 4 will withdraw the backing plate 70 as shown in said figure thereby releasing the type characters 68 so that it can be interchanged or adjusted from above the frame 160 and this same movement also swings the frame 160 into the inclined position so that the upper ends of the type characters are presented at a convenient angle to be manipulated.

The machine herein shown is provided with a safety attachment which will automatically move the backing plate 70 into its operative position when the machine is started in case said plate has been left in the inoperative position shown in Fig. 4.

The crank arm 14 is provided with a finger or extension 80 which is adapted to engage a pin 81 extending laterally from the upper end of the lever 77, see Figs. 3, 4, 7 and 13.

The one-revolution clutch mechanism above referred to by which the machine is driven will preferably be so arranged that it will be disconnected just after a printed impression has been made and while the head is travelling from printing to inking position.

The rack bar 19 is acted on by a spring 82 which tends to hold it in its elevated position and hence when the clutch has been disengaged the printing head will come to rest in substantially its highest point as shown in full lines Figs.

I 94 which reciprocate in bearings 95.

plate has been left in its inoperative position shown in Fig. 4, then during such initial movement of the head 13 the finger will engage the pin 81 and swing the lever 7'? into a position to carry the plate 70 in its operative position. This closing movement of the plate 70 will thus occur before the type characters have been brought into engagement with the inking pad. Said finger 80 and projection 81, therefore, constitute a safety device to ensure that the backing -late '70 will always be in operative position when the machine is started and before the type have been brought into engagement with the inking pad.

The inking pad is mounted for turning movement so that diiferent portions thereof are presented to be engaged by the type characters at each operation. This pad is carried by a turntable 83 and it is given an intermittent turning movement derived from the oscillating movement of the printing h ad. This turntable has a center shaft 84 which is journalled in suitable bearings 85 and which carries a ratchet wheel 36 adapted to be engaged by a spring-pressed pawl 87. he pawl 87 is carried by an arm 88 whi .1 is pivotally mounted on the shaft es and which is connected by a link 89 to an arm 90 that is rigid with the crank 15. Hence as the crank 15 oscillates during the movement of the printing head from inking to printing position and vice versa the inking pad or plate 6 will be rotate so that at each inking operation the type members will be brought against a fresh portion of the inking plate or pad.

Another feature of the invention to which reference has been made above relates to means for scoring or perforating the strip 3 at the points where the strip is to be divided to form the separate tags. This scoring or perforating mechanism is illustrated in Figs. 4, 5 and 6 and it cornprises a platen or work support 91 over which the strip 3 is fed and a vertically-moving scoring or perforating element 92 which is niovabie toward and from the block 91 th reby to perforate or score the strip as shown at 105 in Fig. 9. The scoring element 92 is in the form of a blade provided with teeth and mounted in a verticallyinovable head 93.

Means are provided for reciprocating this I head vertically in timed relation with the feeding movements of the strip 3 so that after each forward step the scoring knife 92 will be brought into engagement with the strip thereby to score the same.

The head 93 is shown as carried by two rods The lower end of the rods are formed as racks 96 which mesh with pinions 9? carried by a rock shaft 98 that is suitably journalled in bearings 99. This rock shaft has an 190 fast thereon provided at its free end with a roll which engages a earn 101 mounted on the cam. shaft 20. Said shaft has another 1G2 fast therewith to which is connected one end of a spring 103, the other end of which is anchored to an arm 1% fixed to the frame 1.

The spring 103 maintains the roll in engagement with the earn 101 and at each rotation of the latter the arm will be depressed thereby I operating through the gears 9'7 and racks 96 to depress the scoring blade into engagement with the strip 3 thereby to score the latter as indicated at 105 in Fig. 9. The strip 3 is held in contact with the block 91 through the medium of direction rollers 106.

Associated with the scoring blade 92 is a strip per plate 107, the purpose of which is to separate the strip 3 from the scoring blade in case there is a tendency for the strip to adhere to the blade when the latter is raised. This stripper plate is retained in position through the medium of two screws 108 which are screwed to the ends of the stripper plate and extend loosely through the head 93. The spring 199 surrounds each screw and is situated between the head and the stripper plate and normally holds the stripper plate in its lowered position shown in Fig. 5. The screws 108 limit the spring impelled movement of the stripper plate.

With the machine organized as above described the strip 3 will be fed from the reel 29 and will be provided with the score lines 105 andthen will be fed through the printing mechanism which will make a printed impression on the sections of the tag comprised between the score lines, the same impression being made on each section. After the printed strip has been taken from the machine it may be divided along the score lines 105 into individual tags.

The tags which are thus made may be used for a great variety of purposes.

In Figs. 11 to 16 we have shown a form of printing head in which some at least of the type are in the form of rotary type wheels. In this embodiment of the invention the type carrier or chase is indicated at 110 and it supports a lurality of rotary type wheels 111 each bearing series of type characters 112. These type zheels are rotatively mounted on a shaft 113 rried in a block 122 and means are provided for adjusting each type wheel independently to bring any desired type character thereon into printing position. As herein shown each type wheel has rigid therewith a ratchet wheel 11%.

The setting of the type wheels is accomplished through a dog member 115 slidably and pivotally mounted on a rod 116 which is carried in a yoke 11''! that is pivotally mounted on the shaft 113. This dog is provided with a handle 118 by which it may be manipulated.

When the dog is swung clockwise about its pivot 116 to disengage its nose from a ratchet wheel 114 as shown by the full line positions Fig. 16, said dog can be moved longitudinally of the rod 116 to bring it into position to engage the ratchet wheel 114 connected with any type wheel 111. When the dog is in register with any particular ratchet wheel th n the dog may be swung counterclockwise to bring the nose thereof into engagement with said ratchet wheel as shown in dotted lines Fig. 16 and full lines Fig. 12.

The dog a locking flange 119 adapted to engage in one of a series of notches 120 that is formed in the bridge piece 121 of the yoke 117 when the dog is in its operative position in engagement with the wheel 114. This locks the dog from movement longitudinally of the rod 116. With the dog in its operative position the corresponding type wheel may be set by oscillating the yoke 117.

During the upward swinging movement of the yoke from the position shown in Fig. 12 to that shown in Fig. 16 the dog will click over a tooth of the ratchet and on the downward swinging movement the ratchet and corresponding type wheel will be rotated. By this means the type wh el can be set to bring any desired printing character thereon into printing position. The pawl 115 can be easily shifted from along the rod 116 to bring the dog into operative engagement with the ratchet of any type wheel and hence the type wheels can be selectively adjusted independently.

The type wheel assembly is removably mounted in the printing head 110. As herein shown the shaft 113 on which the type wheels are carried is supported in a block 122 which is adapted to set into a recess or opening in the printing head 110. This block 122 has a flange or wing 123 at each end which fits into a recess formed in the top edge of the head 110. The block 123 is retained in position during the printing operation by the backing plate '70 which has been above described as operating as a backing plate for the individual type members 68.

When it is desired to adjust any individual type wheel the backing plate '70 is swung backwardly as shown in Fig. 4 and this exposes the dog 115 so that it can be readily actuated to set the type wheels.

Each ratchet 114 has co-operating therewith a spring-pressed stop pawl 124, the function of which is to prevent backward movement of the type wheels. The printing head shown in Figs. 11 to 16 is also provided with additional type members carrying type characters that are situated closely adjacent the operative type character on the printing wheel. These additional type members are indicated at 126, 127 and they are confined between bars 128 and the under faces 129 of the printing head. These type mem bers have an inclined or angular relation and they are provided on their inner extremities with type characters 130 which are situated closely adjacent the operative type character on the type wheels.

Each type member 126, 127 is provided with a shoulder 131 on its under face to engage the outside edge of the bar 128 and with another shoulder 132 on its upper face which engages the edge 133 of the opening in the member 110 that receives the type wheels. The bars 128 are slightly resilient so that the type members 126, 127 can be readily inserted into place.

The bars 128 are carried by the cheek pieces of the frame 13 and the backing plate '70, when in operative position, engages the upper face of the member 110 as shown in Fig. 15. Hence while the printed impression is being made the pressure against the type members 126, 127 will be transmitted directly to the member 110 and thus to the backing plate '70 and the frame 13.
