rmNTING-Pnnss.

To all whom t may concern:

Be it known that I, JAMES M. TRIER, a citizen of the United States, and aresident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Printing-Press, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: To provide a continuously-acting, multicolor printing press having a variety of printing beds, and means for automatically and accurately feeding ink to said beds; to increase the'life of the press; toeconomize the space occupied by the press; to reduce the necessary power for driving the press; and to provide a simple and rapid means for supplying the press with ink. 1

internal flange 23, which has suitably located therein, grooves 24 and gear toothed racks 25. The langes 23 and racks 25 connected therewith are shaped to form rectangular end openings, the corners of said openings being curved, as best shown in the present machine is provided. The ink fountain has ends 34, grooved at the top to engage the rail32 to guide the fountain during its introduction into and withdrawal from the center of the machine.

For this purpose, the fountain is provided with an elongated handle 35, as best seen in Fig. 11 ofthe drawings, and with elongated and projecting shafts 36, the ends 37 whereof are reduced and squared to fit slotted coupling heads 33.. At lone end of the machine, the plate 2G is provided with an opening 39, through which said fountain is introduced, the ends 34 being arranged to engage the rail 32, and the rail'33 of the fountain being seated in the bar 2S.

The wheels 31 are directly connected with the main driving shaft 40 of the machine,

The shaft 40 is provided with a belt-driven pulley 42, or other suitable driving element. The pinions 41 being duplicates, the wheels 31 are driven synchronously. The wheels 31 are each provided with a link arm 43, which arms are secured by pivot bolts 44 to said wheels. The free ends of the arms 43 each/providea bearing for the shaft 45. The shaft 45 has rigidly mounted thereon a cylindrical platen 46 and gear wheels 47, as best seen in Fig. 4 of the drawings. The wheels 47 are held in engagement with the racks 25. To thus hold the wheels engaged with the rack 25, the shaft 45 is provided at each end thereof with freely-rotating carrying Wheels 48. The wheels 48 track on the edge of the guide plates 29, the shape released by the other.A

I whereof corresponds with the-racks 25, be-

a roller`l, to pass over a small cam 52 set out` from the inside of the ange 23, as`

' shown best in Fig. 4 ofthe drawings, and

Iat the upper right-hand corner thereof.

The platen 46 -is supplied with paper di- ,-rectly v from the semi-cylindrical transfer f member 53, which member is provided witha. gripper 54 arranged to operatev in unisonwith the gripper 49 when the forward edge 'ofthe paper she-et is engaged by one and piece'55, the following end whereof passes below and is deflected by a curved plate 56 at the moment of transfer, the constructionl yand arrangementbeing best shown inFig. 9 g of the drawings. The plate 56 and a correspending' plate 57 are arranged for alternate operation upon the tailpiece of the gripper 54.` The former, `as above stated,

. opens the gripper 54 at the moment of trans- `fer of the paper to the gripper 49 on the platen 46. The plate 57 engages the tail- 'i piece 55 when the gripper 54 is moved to the feed table 58, and between the teeth thereof,

in which osition, a sheet of paper resting on said taEle is engaged, to be drawn therefrom as the member 53 is rocked back to meet the 'platen-46 in its orbit.

y The plates 56 and 57 are supported on a reciprocating arm 59, which is provided with a lguide-slot 60 enfolding a rocking shaft 61,` whereon the member 53 is xedly mounted.' The-'opposite end of the arm 59 is provided with a yoke y62, which straddles and is guided by a lay shaft 68. The arm 59 is, reciprocated by a cam slot 64, wherein a roller extends. y'.lhe'slot 64 is plotted to `vproduce the time movement of the arm 59 necessary to present the plates 56 and v57 {to operate upon the tailpiece55 of the/grip- /iper 54. The vslot 641is formed in-a Wheel 66. f'. The member 53 and the shaft 6l n which 'ed by av `rack, arm 67. The rack arm 67 is provided at one end with a yoke 68, which straddles'the shaft 63,' to guide said arm. The I arm 67 isreciprcated by means of a roller 69, which .eXtendsinto a concentric slot' in' a ,Wheel 70.A The'opposite end of the. arm 67 is provided witha Ara'ck sec- ,i formed tion ,71, the-teeth whereof are meshedwith foo the teeth. ofa pinion72, which t mounted on the shaft 6l of thefmember 53.

By timing the cam slots inthe wheels l66 and 70, the

opened and closed to deliver a. thelgrippen49 of the `platen 46, and to engagethesueceeding sheet for removal thereframes @fand 85,

`on eccentrics 86 and 87. The beds 80 `and 8l s retracted within the fr is directly plates 56 and 5.7 are arangedso" thatf the. gripper 54 is sheet ofpaper carried thereby to of from the table 58. The sheetsare held at The rod 76 is extended through and guided 'by a perforation'. 7 7 in one of the frames 22,

andy is furnished at the lower end with a wheel. 7 8 disposed inthe path of a cam late 79, whichis extended from 'the side o one of the wheels 31. The'arrangement of the plate -79 in relation tothe wheel 7 8 is such that the rod 76 is lifted upward, and the shaft 74 is rocked to raise the fingers 73 when the member 53 has been rocked to present the table 58. 5

, The platen 46 is carried bythe `wheels 31,' and is guided by the racks 25 and the gripper 54 to the paper on the plate 29, the wheels 47 at each end of the "shaft 45 engaging the teeth of therack,

over the edge of while the wheels 48 travel the plate 29. A natural rolling action is imparted to the platen 46, 'so that when the platen passes press beds 80 and 8l and forms 8 2 and 83 heldthereon, the paper carried by said platen is rolled thereover, to receive a clear imprint therefrom. Any tendency to slide or produce an independent action of the'platen 46 is corrected by the wheels 47.

It will be understood-that while I have herein shown and gular form,this'may be varied to a' form having an increased number of sides. Coincident with a certain number of straight sides maybe arranged beds such as 80 and 81. ln other words, while I have herein shown two press beds, I wish it to be described a press having theracks 25 disposed in substantially rectanloof straight y understood that the press may be adapted f for the employment 4of a greater number of 1 beds. rlhe beds are each are each provided with groovedsaddles 88. The saddles 88 vare held eccentrics 86 and 87 by. springs 89, which, as shown best inl Fig.` l normally press outward onthe heads of the 'beds 80..and 81; Thl beds are normally mesv 84`andf85 by vanced 'therefrom into position to receive 3 of. the drawings.

U guided in heavy.'v and are therein supported firmly upon the bolts 90, which arerigidly connectedwith y lthe.operation;ofthe springs 89, and aread the pressure of the platen 46 whenthe shafts A` `91' and 92 aresuitably rocked to interpose lthe greater diameter of the eccentrics between said shafts and the saddles 88. To i' l Athis end,veach shaft is provided with 'a crank :arm v93.` The crank arms 93 are connected lin couples by means of connectingr rods 94 and 95, with crank arms 96 and 97 respec-y tively of a bell crank lever-98. ,The lever 98 is pivoted on a stud 99, suitably disposed on :aliases the frame of the machine, and is connected, by means of a'rod 100, to a hand lever 101 The hand lever 101is pivoted at 102 on the frame of the machine, and is provided with a handle 103 disposed convenient to the operating position of the attendant.

-The construction and arrangement as above set forth enables the attendant to quickly retract the beds and 81, to discontinue the printing.

The forms 82 and 83 are secured to the beds in any suitable manner. 1n the usual operation of the press, either of the forms may be used for printing with colored inks. To this end, the fountain is centrally divided by a ridge 101, which arrangement permits the fountain to carry on one side of said ridge, a supply of ink distinct in character from that supplied to the opposite side of said ridge.

The fountain is also furnished with separate feed rolls 105 and 106, which are partly immersed in the ink carried by the fountain. The rolls, as formerlystated, are mounted on the shafts 36, which are arranged t0 be removably connected with the coupling heads 38, which are rigidly mounted on short shafts extending through one of. the face plates 26, to have fixedly mounted thereon ratchet Wheels 107 and 108. The wheels 107 and 108 are rotated intermittently by means of rocking arms 109, which are coupled by a link 110, as best seen in Figs. 2 and 10 of the drawings. The link 110 is pivotally connected with a reciprocating rod 111, the opposite end of which is provided with a yoke 112, which straddles, to be guided by, the lay shaft 63. On the shaft 63 is mounted an eccentric 113, having ar groove 114, into which the roller 115 extends. The roller 115A is mounted on the rod 111, to move the same in a reciprocating manner when the cam 113 is revolved. As the arms 109 are rocked, pawls 116 and 117 alternately engage the wheels 107 and 108, to rock the shafts 36 connected with the rolls 105 and 106 in a corresponding manner. The ink thus extracted from the fountain is spread upon ductor rolls 118 and 119.l The ductor rolls mentioned a'rc pivotally mounted in the ends of swinging arms 120 and 121. `The arms 120 and 121 are ixedly mounted on rocking shafts 122 and 123, which shafts are pivotally mounted in both of the end frames, and are provided with crank arms 124 and 125, respectively. The'arms 124 and 125 are pivotally connected .with reciprocating rods 126 and 127, respectively, as best seen in Figs. l and 2 of the drawings. The rods 126 and 127 are provided with yokes 128 and 129, respeetively, said yokes straddling, to be guided by, the lay shaft 63. Disposed between said yokes and the rods 126 and 127 is a cam Wheel '130, which is provided with Amoved into eng y l gagement is obtained by the rods 126 and'v plotted Yto operateY are provided with shafts 135'and 136, .re-

The shafts v135 and 136 and v1612 are moved in the openings 138A and 139 bythe plates 29 and the racks 25. To this end, the shafts 135 and 136 are each-'provided with a traction wheelle, which rolls over the edge of the plate 29, as seen best in Figs. 6 and 7 of the drawings.

rate of rotation of r111e pi'nlons 1111 are By reason of the above-describedl con-` struction, it will be seen that the rolls 133 and 134 have imparted theretol an inde-, pendent rotary action adapted to rotatethe ductor rolls118 and 119 when the same are agement therewith. This en- 127 rocking the a'rms 124 and 125 at the proper moment to insure the contact of the ductor roll 118v with the roll 134. *In this The shaftsV 112 are and the pinion 111 manner, the rolls 133 and 134 are fed inksl l of diHerent colors, and in timed relation to the beds 81 andSO, upon, which the ink is delivered. The spreader rolls 133and 134v aregeach provided with a train of distribut' rolls mounted on shafts 145,146 and liver the ink to and 83, When moved towar/d the beds by the The' rolls on the last named shafts de the typein the forms 82' supporting Wheels 148 dropping into the:

In this manner is ink to the form on one of the beds 80 or 81 designed therefor, and delivered from the fountain byv the'ductor roll 118 or 110, respectively.

l/Vhen the wheels 148 travel on the surface of the flanges 23, the rollers on 'the shafts 147 pass above and out of contact with the forms 82 and 83. Also, it will be remembered that when the beds 80 and 81 `are retracted, the rollers carried by the shafts 147 do not touch the forms 82 and 83,

insured' the 'delivery of v though the Wheels 1118 grooves 24.

The shafts 146 and 147 are mounted in bearings incoupling plates 151. Each of the coupling plates 151 is provided with a stud shaft 152, bearings for which are provided in the boxes 1&9 which are slidably mounted in the openings 150. This isy best shown in Figs. 5 -to 7 inclusive of the drawings. By this construction, the proper arrangement of the shafts 147 and the shafts 135 and 136 is maintained: The shafts 145 and 146 are coupled by links 153, and the shafts 14:5 are coupled-with the shafts 135 and 136 by swinging arms 15i. The arms 15% are pivotally mounted on the shafts 135 and 136, and are controlled by springs coiled on the shafts 135 and 136, the hook ends 155 of said springs extending over the arms 154e to normally move the free ends thereof and the plates 151 connected therewith toward the racks 25. *Y

It has been explained how the Vpaper is transferred from'the table 58 to the platen Li6, :also how, While carried by the platen,

the paper is imprinted by the forms 82, and 83 on the beds 80and 81. After being so imprinted, the paper is taken from said platen by one of more gripper jaws 156, which are pivotally mounted on a shaft 157 to operate in conjunction with stationary jaws 158 carried by the same shaft. Said shaft is mounted at the free ends of swinging arms 159. The arms 159 are fixedly mounted upon a rocking shaft 166, having bearings in lugs 161 at opposite sides of the machine. T he shaft 160 has lixedly mounted thereon a short lever 162. The lever 162 is rocked by an arm 163, which, as shown best in Fig. 13 of the drawings, is provided with a yoke 16e to straddle the lay shaft 63, to be guided thereby. .1. Y

A roller 165 mounted on the side of the arm 163 extends Within, to be engaged by, a cam slotr166, with whichY a wheel 167 is provided. The wheel 167 is fixedly mounted on the shaft 63, and theuslot 166 is plotted to move the arm 163, shaft 160,"arms 159, shaft 157 and jaws 156 in timed relation wit i the a curved gade plate 169. The plate 169 is provided as a track for a roller 176'atthe end of a tailpiece 171 connected with the jaws 156. At the ends of the plate 169 are risers 172, which, by defiecting the roller 170, operate to open the jaws' 156, to receive and to deliver the paper in consonance with the movement of the parts ofthe machine.
