BOX-WRAPPING MACHINE.

To all whom it may concern:

Be it known that we, JUHN P. MAnxeR'r and ROBERT S. Bounce, citizens of the United States, residing in the boroughs of Brooklyn and Queens, respectively, in the city and State of New York, have invented certain new and useful Improvements in Boxrapping Machines, of which the fol lowing is a full, clear and exact description.

This invention relates to box covering or wrapping machinery and has for one of its objects the provision of means for increasing the output of mechanisms of this character.

Another object of the present invention is to insure safety to the machine operator.

A still further object of the invention is to so reduce labor that a single attendant can operate the complete mechanism and can by its aid center the box upon its wrapper and cause the box and wrapper to be automatically conveyed to the wrapperfolding devices.

These and other objects of our invention will be hereinafter referred to and the novel combination of elements whereby they may be attained Will be more particularly set forth in the appended claims.

In the accompanying drawings which form a part hereof and in which like reference characters designate like parts throughout the several views, we have exemplified a preferred form of apparatus. We are aware, however, that many modifications and changes in said apparatus may be made within the purview of our invention and hence desire to be limited only In the drawings: Figure 1 is a horizontal section of said mechanism, the section being taken ..n line I-I of Fig. 2. Fig. 2 is a vertical, longitudinal section taken on line 11-11 of Fig. 1. Fig. 3 is a view similar to Fig. 1, but showing the box shifting mechanism'in its delivering position. Fig. -'lis a section taken on line IV-lV of Fig. 3, some of the parts shown in the similar Fig. 2, being omitted.

The box wrapping mechanism herein shown comprises a frame 1, upon which are mounted various elements of the mechanism. VVithir this frame are two opposed plungers, preferably movable vertically, the lower of said plunger-s being designated 2 and constituting a table or support for the Specification of Letters Patent.

box when the wrapper is being applied thereto. The upper plunger is preferably a wooden block 3 adapted to enter the box and clamp the bottom thereof against the plunger 2. These plungers may both be positively actuated, if desired, the lower plunger 2 heingmounted upon a reciprocable standard or shaft 4 which rides in a guide 5 and is reciprocated therein by means of a bell-lever G keyed to a rock shaft. 7; the longer arm of the said bell-lever being connected to a projection S of the standard 4 The short arm of the bell-lever is connected by means of a link 10 to a lever 11 which is pivoted to a bracket 12 which extends forwardly from the frame 1.

It may here be noted that the front end of the machine has been disposed at the left hand side of the sheets in the drawing.

- The upper extremity of the lever 11 carries a roller 13 which rides in the cam-slot 14 of a cylinder 15. This latter element is mounted upon a shaft 16 which is driven in any suitable manner as by means of a spiral gear 17 which is adapted for engagement with a similar gear 18 mounted on a transverse shaft 19, driven by a pulley 20.

The upper plunger 3 depends from a reciprorable shaft 21 which rides in a suitable bearing carried by the bridge 92 of the frame '1. The upper extremity of shaft 21 may be linked by means of a connection 23 to a bar .34 which extends downwardly through a lateral extension 25 of the bridge 22. The lower extremity of bar 24 is connected by means of a link 26 to bell-lever 27 which is pivoted to the extremity of the bracket 12 above referred to, as at 28. The short and preferably upwardly directed arm of the bell-lever 27 carries a roller 2.) which rides in a cam-slot 30 in a cylinder 31. (Tylinder 31 may be disposed immediately adjacent cylinder 15'): both of these cam cylinders being mounted upon the shaft 16. The respective cams are so shaped that upon the upward stroke of the plungers actuated thereby, the pressure block or upper plunger 3 moves upvardly, at least during some portion of its stroke, faster than the lower plunger or table 2. thereby separating the said plungers to admit of the reception of the box and its wrapper therebetween. iV hen the phmgers descend, the cams are so configured that the upper plunger descends by means of a link 9.

into the box and firmly presses it against the table plunger, thereby clamping the box against displacement and carrying it down-- wardly togetherwith its wrapper between 5 the folding rolls 32, and other parts, some of which have not herein been shown since they per .56, form no part of the present invention. J I p Theframes 1 and brackets 35, which project out toward the front of the machine -therefrom', support a. table 36 and upon either sideof, the machine and also supported bysaid brackets and the bridge 22,

above referred to, are guide rods 37 Slidably mounted on these guide rods are the traveling frames 38 whic are connected together-bymeans" of two cross rods 39. Con

nected to these' crossrods by means of brackets 40-40 are a seriesof rails or sup- 'o porting bars for the labels or wrappers to be handled by the machine. These support bars have been design adjustable along the length of the cross rods so as to accommodate wrappers or labels of 'g'wa'rious widths.

They may be clamped in osition upon'the cross rods by means of olts 42. The traveling frame is connected as at 43 to chains ,44; one of which is disposed upon either side of the machine. At

0 the forward end of the machine these chains pass over idler sprockets 45- and at the rear end over-sprocket wheels 46. These wheels are fixedly mounted upon a shaft 47, which is journaled'in' brackets 48, secured to the. at?

rear end of. the frames 1, and this shaft is which is .in'mesh with a gear segment 50,

pivotally connected. at 51 to a bracket 52, which latter is also secured to the 'rearend 4o' 'of one of th'frames.'-.

caused to rock means of a'cam 52 inount ed upon the. rear extremity.ofth'e shaft 16 .above referred to. The cam slot in the cam '5 cylinder 52 has been. designated 53 andiis adaptedfor; the reception. of a roller 54 which is mounted. upon the outer side of the arm of 'ar segment, as-shown in Fig. 4..

It is'evi ent' therefore that rotation of shaft ment andthereby cause shaft 47 torock.

- As. this shaft carries the sprocket wheels 46, the chains 44 will"be pulled around firstin one, direction and then, in the other; and as.

55 the traveling framesf38 are connected to these';chains, theyalso will becaused to re-' ciprocate toward and from theplungers. 1

The brackets 409440, flcarr gages for centering-the'boxand.itsilabe for wrapper so eo 'thatthey' may be moved'by'the traveling frame directly into position upon the lower plunger. To. this end we may provide box gages 55 which are connected the inner pair of brackets, 40, and a label or wrapper gage 56 which may be connected to one of ated 41 -41 and are driven by means of a pinion 49 thereon The gear segjment mount dtnistud '51 is.

16 will effect an oscillation of the gear segthe oiiter bars 41. These" ages areprefit erably resilient, especiallyt osewhich are I adapted to engage the box; which latter,

' designated 55, are secured to their respective support ng brackets by means of bolts 57 and may have the bodiesthereof slotted as at 58 for engagement with a screw 59 which secures the front label gages 6O adjustably thereto The gage 56 is also preferablymade adjustable lengthwise of the adjacent bar 41.

The operation of the mechanism is'as follows: Assuming that the traveling frame is disposed as shown in Fig. '1 and that it be desired to cover loose-wrap boxes, the op-' orator stations himself at the front of the machine adjacent the outermost positionof the travelingfraine and places a wrapper or label 61 upon the supporting bars 41, 41

accurately positioning the wrapper by means 5 of the sidegage 56 and rear gages60. He"

then places a box 62 upon the' wrap er, ceni te'ring it accuratel with respect to t e plun gers by means of the box gages 55. The" traveling frame is then caused to traverse the Y guide rods 37 throughs the instrumentality of the chains 44 in the manner above described, and during a portion of one rotation of the cam 52 and also, of course, of the' shaft 16, the traveling frame will advance from the position in which it is shown in Fig. 1 'to that in which it is shown in Fig. 3, thereby placing the wrapper and box directly in position upon the lower plunger.

The continued rotation ofshaft 16 causes 66 erations which may be performedin apply- 0 ing the, wrapper to the .box after the wrapper has been folded over against the side' I walls of'the box by being passed through the wipingrolls It is important to note, however, that before the plunger descendsv with the box andits Wrapper, the smooth support barsl41, 41f are withdrawn from b eneaththe wrapper by means of the traveL ing frame and its operating mechanism' Sincethegagesareall in engagement with 126- those portlons of the box and its wrapperwhich are nearestto the'operator, or to the front of the machine, there is noth-in to hinder their beinggdraw'n freely away rom the box andwi'a'p er when these havebeeir I clamped between t e plungersj in the manner, described. pItis'essential, however, that this l clamping or gripping action should have occurred before the withdrawal of the supporting bars, since otherwise the wrapper 130 would probably be displaced with respect to the box, unless some equivalent wrapper holding means he provided. The wrapped box is preferably fed downwardly through lowed to dwell for some time at the front T end, of the machine, affording the operator sufficient time to place the next wrapper or label and box upon the support bars carried thereby. This turn conveyed toward the ox and its wrapper are in plungers in the manner already described, completing the cycle of operation.

If it be desired to cover tight-Wrap boxes,

- the adhesive initially applied to the wrapper or to the box by the operator, or by a gumming machine,'will hold' the box and wrapper together, so that the gages 56. and

60 maybe dispensed with, if desired. [In operating upon either tight or loose wrap boxes however, it will be observed that the box andits wrapper are disposed in juxtaposition" ata point readily accessible to the I" machine operator and are conveyed together to a point substantially in alinement with the plungers. It is desirable also that the support bars should be withdrawn before the plu'ngers descend, to avoid complication of the mechanism. I

Finally we desire to call'attention to the fact that it is by no means essential that V both of the plungers or even one of them, be

made movable but in general may state that it is necessary that some form of coverin blank (or strip) folding means be provide as well as some means, preferably clamping in character, for holding the blank and box together while subject to the action of said folding means; that one of these said means be movable with respect to the other in a determined line or path; and that some form of movable support be provided 'for transferring the coverin blank to a point in said line or path. It is urther, practically essential that the support should move toward the aforesaid movable means in timed relationshi to -said means.
