BOX-COVERING MACHINE.

'Be "t known that I, FRED R. HARRIS, a.

j 'citizeiiof the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Box covering Machines, fully described and represented in the following specification and the accom- -paiiying drawings, forming a part of the saiiie. i Thisinvention relates to machines for covering boxes and more particularly to machines for applying a covering sheet or strip of suitable material to the bottoinand top of a'box and about the hinge side thereof.

' In some cases the covering'material so applied may serve to secure the body and cover portions of the box together and to form the hinge.

The invention has been made particularly vwith the idea of covering and hinging together the cover and body portions of boxes, the cover and body portions of lilCh are each provided with side "flanges, the side.

flanges of the cover portion of the box extending Outside of the side'flanges of the body portion of the box. It will be understood, however, that the invention may be used for covering and hinging together the cover and body portions. of boxes of otherforms. I

A full understanding of the invention can best be given by a detailed description of a preferred 't-oi sti-uction embodying thevarious-feaiures thereof. and such a description will now be given in connection withthe accoi'iipai v'iiigdrawings showing such a prefei'rcd construction for covering boxes of the form above referred to.

In said drawings :-Figure 1 is a side view of such machine. Fig. 2 is a plan view of the same. Fig. 3 is an end view looking in the direction of the arrow 3 of Fig. 1 and showing the frame partly in section. Fig. 4

right angles to Fig. 8. Fig. 10 is a detail view of parts shown in Fig. 8, showing the same in a different position. Fig. 11 is a view taken at right angles to Fig. 10 and showing parts omitted from Fig. 10, and

Fig. 12 is a cross sectional view of the box as covered by the machine.

The-covering sheets or strips are prefer ablyout from a web orv continuous strip which is fed from a. roll and pasted as it is advanced to the cutting mechanism. Any

suitable means may be employed for so feeding, pasting and severing. the strip of covering material. As shown the strip w is drawn from a web roll supported on a shaftcarried by suitable hangers-10 by means of a pair of feeding rolls 11, from which it passes between a pa sting roll 12 and a supporting and pressing roll 13.' .The pasting roll 12 is supplied with paste from a fountain 15, the

roll'being mounted in bracket arm's extending from'the fountain'so as to rotate past the outlet opening of the fountain, and a plate 16 adjustable toward and from the pasting roll is provided for regulating the thickness.

of the layer of paste carried forward by the' pasting roll.' 'An' adjustable scraper 171s also provided for cleaning the surface of the pasting roll as it'returns to take paste from the fountain. The pressing roll 13 is mounted'to move toward and from thepastingroll,

as by being journaled in a frame18 mounted to slide in ways. 19, and is held inoperative position under yielding pressure by means of a :pri g 20 acting to press the frame 18 upwe d award the pasting roll. A thumb nut 21. on a rod extending downward from the frame 18.serv es as a stop to limit theupward movement'of'tlie frame and pressing roll, and by turning the thumb nutthe position to which the roll may be pressed toward the pasting roll by the spring may be adjusted. To permit the pasting roll to be raised, as for the purpose of threading or drawing the strip between the pasting roll and'the supporting roll,the fountain is preferably mounted to slide in vertical ways 25 ing their lower, ends provided with or con nected to-riiigs on eccentrics on a shaft eX- tending beneath the. fountain and provided at one end, as shown in Fig. 7, with means whereby'it may be turned by hand for raising' or lowering the fountain and pasting pressing roll.

roll when desired., Spring fingers'28 are preferably provided for bearing against the faceofthe pasting roll to insure the strip leaving the roll as it advances beyond the The pasting rolland the supporting roll are geared to turn together by means of gears and 31 respectively on the shafts of said rolls, and are continuously driven by means of a pinion 32 which meshes with a gear on the shaft of the pasting roll, said pinion being driven from the cam shaft 35 by means of a sprocket chain 36. The feeding rolls vl1 are geared to turn together and are continuously driven by means of a sprocket chain 37 from the shaftof the pressing roll 13.,

After leaving the pasting rolls the strip passes over a su 'oporting plate'or guideway 38 from which the end of the strip is drawn past the severing means and the severed por tions' then advanced to the covering means. As the strip is drawn over the support 38 intermittently and is fed from the pasting rolls continuously, the support 38 is preferably placed, some distance beyond the pasting rolls so as to allow the, portion of the strip between the support and the pasting roll'to fall in a loop during the intermissions between its movementover the support. Strip feeding, aasting' and severing means comprising means for continuously feeding and. pasting the strip; a support beyond the pasting means, and means for advancing the end of the strip intermittently over the support and past severing means is described andclaimed in my application No. 182,569, filed November 25, 1903.

Any suitable severing means may be provided. The preferred means shown c0111- prises a stationary lower blade 40 and a movable upper blade 4:1 which is preferably pivoted on one of a pair of guide rods 42,

43, and is oscillated intermittently by means of a lever 44 connected by a rod 415 with an arm .46 mounted to oscillate with the knife blade, said lever is carrying a camroll which runs in a cam groove 47 in the face of a cam disk 48 on the shaft 35. 49 is preferably provided lying above the path of the covering strip to wipe the'faee of the blade 41 as it rises after making its severing movement.

For drawing the end of the strip of cow ering material between the knives and then advancing the severed portion to the covering means, a pair of surface grippers 50 are preferably provided, said grippers being carried by a sliding frame or carriage 51 mounted to slide on'the guide rods 42 and and reciproqated to give the grippers their .feedingand return movements by means of 'face of acam disk 56 on the shaft 35.

therewith.

A wiper cam roll running in a cam groove in the The grippers 50 are carried by rods extending from a shaft 57 journaled in bearings on the carriage 51. Springs 58 on the shaft 57 tend to rotate the shaft to raise the grippers, and the grippers arethereby normally held in the slightly raised position shown in Fig. 8, the rotation of the shaft and upward movement of the grip ers being limited by adjustable sto )s 59 which are engaged by lugs (30 extent ing from collars on the shaft 57. The grippers being in this normal raised position as the carriage makes its return movementxto carry the grippers into gripping POSltlOH, the grippers will llE slightly above the support 38 so that they may be moved over'the endofthe covering strip lynig on the support without engaging As the carriagereaehes the end of its return movement after the grippers have been advanced overthe end of the support 38, downwardly extending lugs (31 on" the collars on the shaft 57 engage adjust-' able abutments 62 whereby the shaft is rocked against the tension of the springs 58 to throw the rippers down into contact withthe paste surface of the end of the; covering strip, as shown by dotted lines in Fig. 8. The carriage and grippers then start on their feeding movement. to the right in Fig. 8, and the end of the strip is thereby drawn between the severing knives. When a sufiicient length of the, covering strip for.

covering a box has been drawn beyond the severing kn ves, the gripper carr age is momentarily stopped while the severing blade i1 is actuated to sever the strip. The-car- 'riage then completes its forward or feeding movement to carry the severed portion of the strip into covering means.

It will be noticed, that the surface contact grippers 50 which depend on the adhesion of their gripping faces to the pasted surface of the covering strip, form a non-positive feeding meanswhich permits of a slip between the grippers and the strip if the movement of the strip is resisted, It is often desirable that the covering material to. be applied to the boxes shall be printedor otherwise pro-- [05 position with relation to the vided with suitable lettering or other matter for forming labels or with suitable decorative matter. and when the continuous strip of coveringmaterial is printed so that successive portions thereof bear the printed matter of successivecovering sheets. it l necessary that successive sheets shall he cut from the strip to correspond with the ma ter printedthereon. To secure this result i make use of a non-positivefeeding means. such as the surface engaging'grippersno.

a lever 52. the lower end of said lever being and Tn'ovidemeans for engaging registering connected by a rod '53 with one arm of a i devices on thestrip to hunt the movement of lever 54 the other arm of which carries a l the strip by the grippers. .Such registering devices are preferably'formed by a succes- S1011 of perforations formed at intervals in thelstrip corresponding to successive sheet todetermine the extent of movement of the strip at each feeding movement of the grippers 50, a pin 65 is provided pro ecting slightly above the surface of the support 38 and a presser, formedpreferably by a flanged roll 66 carried by a pivoted arm 67 on a rock shaft 68, is provided for pressing the covering material against the pin. Such arm and pressing roll are normally held in operative position with the roll bearing yieldingly against the strip of covering material'on the support 38 and over the pin by means of a spring 69 on theshaft 68. The shaft 68 also carries a rod TO extending toward the gripper carriage 51 in position to be engaged by a lug 71 carried by the gripper carriage before the carriage-reaches the end of its return movement, whereby thepressing roll 6(3-is raised as the rod 70 is de-. pressed by the lug 71 and is held in its raised position during the remainder of the return movement of the gripper carriage and during the first part of its feeding movement. T hen when the gripper carriage has made a portion of its feeding movement the roll 66 again allowed to press the strip lightly against the pin so that when the strip has been moved a distance to bring another of the perforations :0 to the pin 65 the pm will be caused to project through such opening and the movement of the strip stopped, the

grippers thereafter slipping on the strip during any furthermovement they may have before coming to rest for the operation of the severing blades. As the grippers again come into gripping position, the pushing roll (36 is again raised from the strip of material to permit it to be drawn forward another sheet length by the grippers. It will be seen that by providing such interrupting means in combination with the non- .iositive feeding means. and by giving the grippers a slightly greater movement before. the rest for the ope ation of the severing means than is necessary to feed a sheet length of the covering strip. the successive covering sheets will always be cut accurately between the labels on the strip.

For holding the strip ofcovering material hit on the support 38 a number of pressing fingers 72 are preferably provided. as shown in Fig 2and 5.

- The boxes to be covered are supplied to the. machine with. the body portions and cover portions of the boxes associated to gether and ready to have the covering sheets applied to the bottom and top and about 'one side thereof. The boxes are .placed' in .a holder 75 through whiclrthey are advanced -l slightly backward and out. of contact with fiat-wise on edge by means of belts 76 mounted on vertical rolls 77 and 78 having their inner or feed runs extending inside the opposite side walls of the holder. For press-- ing the inner runs of the feed belts 76 in ward and adjusting the pressure on the boxes, pressing rolls 79 are provided as shown in Figs. 2 and 3, such rolls being preferably carried by arms pivoted on the shafts of the rolls T7 and 78 and adjustable by means of adjusting screws 80. The belt rolls 7? are geared together. as shown in' Fig. 2, and the shaft of one of said rolls is extended downward; and driven by bevel gears" 81 from a shortshaft 82,. w'liicl1 is driven by a sprocket chain 83 from the main driving slia t 85. The row of boxes in .the holder isconstantly pressed forward by ,the belts 7G to carry the end box of the row against the front plate 86 of the holder, and from this position the successive end boxes are fed edgewise downward by meansof a plunger 8?. vThe holder is preferably pro-. vided with'ayielding bottom at the delivery end of the holder; such portion of the bottom of the holder}being formed by means ofa pivoted p'late'SS normally held in support-' ing position by means of springs as shown in Fig. .1, and adapted to turn downward to the position suown in dotted lines in Fig; 9 as the end box is forced downward from the holder. The plunger 87 is reciprocated by means of a lever 90 carried by a rock shaft 91 which shaft also carries an arm 92 connected by a link 93 with a lever .94 whichcarries a cam roll running in a face of the cam disk 56 cam groove in one on the shaft When the box bodies and covers-are provided with covering material'about the sides thereof the edges of wvhich. are turned ov er againstthe top'and bottom. said turned over edges are liable to become displaced or injured by the movement of the end box against the next box in the holder as it i pushed downward by the plunger 97. To avoid this ditliculty there is preferably provided means whereby. asthe plunger makes its downward movement to push the end box out of the holder, the next box will be moved slightly backward in the holder away from the end box so that the surfaces of the two boxes will not'be in contact as the end but movedfromthe holder. For-thi purpose the plunger 87 istp'referably provided with a rearward extension 95 having a beveled or. wedge shaped lowerend for engaging the next to the last box in the holder to push the same back slightly in the holder as the the last box in the holder will thus be forced lOU force the'box and covering blankdownward between a pairof folding and pressing roll- -ers 100 whereby the blank is folded upward and pressed against the top and bottom of covering blanks are fed and supportedby the .end box in the holder as the latter is moved edgewise from the holder, and all ,-:danger of injury to the boxes by reason-f one sliding against the other is thereby avo ded.

"The covering sheets are carried by the 'grippers 50 into position beneath the end of the box holder so that the central portion of the"blank will lie directly beneath the end box in the holder. The plunger 87 makes its downward feeding movement after the envl ering-blank has been carried into position I and thereby forces the end box in the holder downwardto carry thelower edge or side of the boxaga nst the covering blank and to the box. A second pair of rollers 101 is pref- 'erably provided beneath the rollers 100 for further, pressing. the covering 'm'aterial against the'top and bottom of the box as the box moved downward between said rollers.

.To .avoid the necessity of having the plunger 87 make. such a long feeding move-.

' mentas would be required to move the box I between and clear of the pressing rolls, other feedingmeans arepreferably provided for engaging the box after it hasbeen forced bel'tween the folding rolls andfor moving it the remainder of the distance to carry it clear of said rolls. The plunger is preferably given a reciprocation sufficient to carry the upper edge of the box below the plane in which the the feeding grippers 50. For completing the movement of the box between thefolding and pressing rollers 1-00 and 101, a pair of feeding arms '102 is preferably provided having inwardly extending ends or shoulders '10? adapted to project over and engage the upper edge of the boxw'vhich has been. pushed downward between the'rolls by the plunger, such feeding armsbemg preferably pivotally I mounted in a reciprocating support 1.01 which support is preferably mounted to sllde vertically in ways 105 and reciprocated by means of a lever 106 which carries a cam roll running in a cam groove in one face of acam disk 109 on the shaft 35. The feeding arms 102 are normally thrown outward to the non-operative position shown in Fig. 8

' in the support 104 and normally stands in position withrelation to the support 104 as shown in Fig. 8, being held in position prefer'ably by means of a friction spring 112.

As the plunger 87 moves downward, the

support 104,: feeding arms 102 and presser bar 110 stand in the position shown in Fig. 8, and-a covering blank has been carried into position by the grippers 50, as shown in said figure. As the end" box in the holder is pushed downward from the'holder by the plunger, the bottom edge or side of the box 'engages the central portion of the covering sheet and carries it down against the presser bar 110, as indicated by dotted lines in Fig. 9. The downward movement of the plunger then continuing, the box is pushed downward between the folding and pressing rolls and the pressing rolls 101, the presser bar being forced downward by the box while the support 104 remains stationary, and the downward movement 'ofthe plunger continues until the box. and-presser bar are in f the position with relation to the support 104: and. folding and pressing rolls shown in Figsr l0 and 11. The extending portions of the covering sheet are thereby folded upward against the top and bottom of the box, and asthe presser bar'approaches the support 1041 it engages the upwardly projecting ends of-the rods 108, thereby forcing said .rods

downward whereby the feeding arms 102' are lswung inward to-the position shown ill Fig.

10 to carry their inwardly extending ends 103-over the upper edge of the box. The support 10tis then moved downward to the position shown in Fig. 5, thereby drawing the box down between and clear of the pressing rolls, the plunger 87 meanwlnle being returned to the positlon shown in Fig. 5 to permit another covering sheet to be carried into position by the feeding grippers 50, and

to permit the next box in the holder to be advanced intouposition to be fed downwardly by the next downward movement of the plunger. By. its passage between the folding and pressing rolls 100 and 101, the covering sheet will be pressed smoothly against the top and bottom of the box, and the portion of the sheet extending about the lower side of the box; will be pressed firmly against such side by means of the presser -bar 110. It will be noticed that the pressureof the presser bar against the lower side of the box is increased by the resistance of .the spring pressed bars 108, and such resistance may be adjusted to give the desired pressure on the portion of the covering sheetsecured to such side ofthe box. The application of the covering sheet to the box being thus completed, the box is-delivered preferably by means of a horizontally re 1 ciprocating plunger 115 carried by a rod 116 in position to engage the covered box as it is supported by the feeding arms and presser bar and force it fiatwisetherefrom and into a delivery chute 117 from which the box may be taken by handor received by suitable receiving devices.
