To aZZ 'wlwm it may Gomera:

Be it known that I, TILLIAM Booon, citizen of the United States, and resident of Nutley, in the county of Essex and State of New Jersey, have invented certain new and useful mprovenients in Machines for Making Cell-Cases, of which the following is a specification.

The invention relates to improvements in machines for making cell-cases for packing eggs and other articles, and includes a feedtable adapted to receive successive sheets of card-board, means for feeding the sheets therefrom at regular intervals, means for longitudinally sooring the sheets, means for longitudinally severing the sheets into strips, means for applying lines of glue or other adhesive thereto, means for collecting or laterally spaoing the severed strips in separated and overlapping relation with one another, and means for advancing and compressing the collected strips for the adhesive connection thereof. And the invention further |includes a particular form of collecting device whereby the strips are more perfectly alined with respect to one another.

In describing the invention in detail, reference is had to the accompanying drawings, forming a part of this specification, wherein like characters of reference designate like parts throughout the several views, and in which:

Figure 1 is a ground plan of the machine embodying the invention; Fig. 2, a sectional side elevation of the same; Fig. 8, an enlarged sectional transverse elevation of the strip collector, showing the Operating mechanism thereof; Fig. 11, a detail View showing the relative lateral collected position of the several strips of cardboard withthe glue and score lines therein; and Fig. 5 is a perspective view showing a finished cell-case in open position.

In the drawings, numerals 1 and 2 designate respectively the fro'nt and rear frames of the machine, provided with suitable cross-braces 8 and 41. -Upon one end of the frames is mounted a feed-table 5, and to the opposite end thereof frame extensions G and 7 are secured through the cross-brace a. Mounted in bearings upon the frames are two pairs of feeding rollers 8 and 9, and also journaled in the frames intermediate of the feeding rollers are two pairs of shafts 1 0 and 11, respeotively carrying conventional scoring or creasing wheels 12 and slitting-wheels 18, the wheels of the respective pairs being opposed to each other for the passage of the cardboard therebetween, the creasing-wheels thereof being arranged to form a plurality of single and double score-lines longitudinally of the Sheet. Mounted upon the opposte frames are a pair of brackets lt, in which are journaled the upper and lower' shafts 15, carrymg the feed-pulleys 16, and also supported from these brackets by the integral arms 17, is a fixed shaft 18 arranged to carry a gluebox 19, provided with a removable bottomplate 20. lVithin the glue-box is journaled a shaft 21, carrying a series of glue-wheels 22, which pass through slots in the bottom plate and project below the bottom surface thereof and are provided in the usual manner with adjustable scrapers `for regulating the quantity of glue thereon. Suitable feed openings or passages, not shown, are provided Iin the top wall of the glue-box for supplying` glue thereto either continuously or intermittently.

Upon the frame extensions 6 and 7, suitable bearings are provided in which are journaled two pairs of shafts 28, carrying the oppositely disposed upper and lower presser-wheels 24, driven together by suitable gearing 25, which in turn is jointly driven by a gear 26, fixed upon the main shaft 27, the latter being mounted in bearings 28, supported upon the rear frame 2 and cross-brace 4. A main driving pulley 29 is 'fixed to the main shaft, and to the outer end of the latter is also fixed a bevel gear 80, which engages a corresponding gear 81, fixed upon the way-shaft 82, and is driven therewith at a common rate of speed, the latter shaft being mounted in bearings 88, fiXed upon the rear frame 2. The shaft 82 is further provided with two bevel gears 84 which engage corresponding bevel gears 85 and 86, loosely` mounted upon studs 87, fixed to the rear frame. Fixed respectively to gears 85 and 86, and likewise loosely mounted upon the studs 87, are spur gears 88 and 89, the former, by a suitable line of gearing 40, driving the feeding-rolls 8 and 9 and the scoring and slitting wheel shafts 10 and 11, and the latter, by the line of gearing 4-1, driving the feed-pulley shafts 15 and the glue-wheel shaft 21. The gears throughout the machine are proportioned to drive the several feed rolls, scorers, slitters, glue-wheels, and presser-whoels at a colinion peripheral speed, corresponding with the rate of travel of the work.

For feeding the sheets of cardboard at regular intervals from the feed-table, feeddogs 11-2 are provided, which pass through slots -13 in the table, the upper ends of the dogs projecting above the table to engage the rearward edge of the sheet and urge the same into the feeding-rollers 8. Each feeddog is provided at its lower end with a hub, which slidingly engages a pin 44, fixed in the bracket 435, secured upon the bottom of the feed table; a corresponding slot being formed in the foot of the bracket to slidingly receive and laterally' guide the upwardly extending feed-dog. F or imparting movement to the dogs, the lower or hub ends thereof are pivotally connected to one end of the links ati, the opposite ends of the latter being similarly connected to the lever arms '-l-7, fixed upon the rock-shaft S, sup- 5 po Tted for movement in the opposite frames of the machine. Fixed upon the rock-shaft is a lever 49, pivotally connected at its lower end to one end of a connecting-rod 50, the opposite end of the latter being provided 0 with a fricfion roller 51, which is engaged y a cam fixed upon the cam-shaft 52, the

end of the connection-red being slotted and loosely engaging the cam-shaft as a guide in the usual manner to receive the lateral 5 thrust of the cam. compression spring 417, fixed at its opposile ends to the brace 3 and one of the arms T, holds the roller 51 into engagement with the cam. The camshaft is mounted in bearings formed on the 0 front and rear main-frames, and motion is imparted thereto by the gear 53, which is engaged by thel gear 54, fixed upon the main-shaft 27.

F or making the cell-case herein shown,

5 the sheet of cardboard is divided longitudinally by the slitting-wheels 13 into eight strips designated by A, B, C, C1, C2, C3, B1,

A1, those having common letters being of similar widths. From the feed pulleys 16, 0 the strips are directed to a collector 55, comprising a corresponding nun her of fixed supporting-plates, space-d apart from one another and carried by the side b'ackets 56 upon the opoosite main frames of the machine. rf'he plates loosely support the strips of cardboard, and beginning 'ith the lowest plate, the strips are led to the successive upper plates in the order indicated by their successive reference characters, strip A be- O ing carried by the bottom plate and strip A1 by the top plate, the relative levels of the strips being clearly shown in Fig. LL.

For leading` the several strips to the collector, endless tapes or bands 57 are pro- 6 vided, which pass around and are driven by the lower set of pulleys 16, and lead independently to the smaller rollers 58, severally adjustable adjacent the leading edges of the collector plates, a corresponding series of tension rollers 59 contacting the belts to alford a more perfect direction of the strips to the collector.

For transversely spacing the several strips within the collector, a series ofV spacingdogs 60 and (31 are slidably mounted upon a pair of cross-shafts G32, fixed in the brackets 56, see Figs. 2 and 3. Links 63 pivotally connect the dogs to the lever-arms 6a, the

latter belnO' fixed upon the rock-shafts 65,V

mounted in the bearings 6G, and for effecting the forward and baclrward movement of the opposite dogs, toward and from each other, the arms are oscillated by means of the rock-shafts, and the bevel-gears G7, fixed thereon, the latter being engaged by corresponding gears 68, fixed upon the shaft 69, mounted in bearings 70. A rocking movement is imparted to this latter shaft by the lever 71, fixed thereon, and provided with a connecting-rod '72, leading to the camshaft 52, having a cam 73, fixed thereto; a roller T-l, mounted on the connecting-rod, being held in engagement with the cam by means of a tension spring 75, which is fixed at one end to a suitable support 7G, while its opposite end is connected to the lever 71. As thus connected, the cam, at each revolution, corresponding with the introduction of each successive sheet into the machine, imparts the necessary reciprocation to the dogs 60 and 61, the upper ends of which are laterally guided by and traverse the transversely-extendlng slots 77, extendmg through the several plates, and in their forward movement toward each other, engage the outer edges of the strips of cardboard and transversely move them upon the plates into suitable overlapping position with respect to each other, the engaging ends of the dogs being suitably shaped, and in the order name-d respectively adapted to engage strips A, B, C, C1, and C2, C3, B1, A1, to effect the necessary overlap thereof, as indicated in Fig. 4. For limiting the transverse movement of the strips upon the plates, stops, not shown are preferably employed, the same being adjustably fixed to the plates or other' suitable support.

The several collector-plates are vertically spaced by interposed space-bars TS, and are jointly connected together' and supported in connection with the brackets 56 by the upper and lower cross-bars 7 9 and 80, having slots 7 extending therethrough, corresponding with those of the several plates. Upon the upper cross-bars are mounted the slideblocks 81, in which is mounted for horizontal niovement the slide-bar 82, having` at one end a bearing 83 in which is mounted for rocking movement a short shaft 84, upon which is fiXed a pair of feed-fingers 85, adapted to engage the rearward edges of the transversely spaced strips of cardboard and feed them forward by the movement of the slide-bar 82. For this inovement a link 86 is pivotally connected at its ends to a lug 87 on the slide-bar and to the arm 88, the latter being fiXed upon a rock-shaft 89, carried by the bearings 90, fiXed to one of the cross-bars 79. Upon the outer end of rock-shaft 89 is fixed a lever 91, having a pivotal connection to the upper end of the connecting-rod 92, the lower end of which is fork shaped to engage the cam-shaft 52, a cam 98, fixed on the latter, engages a roller 94 on rod 92 to efifect the aforesaid movement of the slide-bar, in connection with a spring 95, the opposite ends of which are connected respectively to an extension of the lever 91 and to the foot of the outer bearing 90, which action of the spring normally holds the roller 94 is contact with the cam and effects the return movement of the slide-bar. At the end of this return movement, the rock-shaft 84, carried by the slidebar, is given a slight rocking movement to tilt the fingers 85 for affording a clearance for the introduction of the strips of cardboard to the collector, the fingers extending downwardly an amount sufficient only to engage their respective strips of cardboard. For this rocking movement, an upwardly-extending arm 96 having a horizontally-projecting lug 97 is fiXed upon the rock-shaft and engaged by a stop-bracket 98, fixed upon the adjacent cross-bar 79, the stop-bracket having at its free end a lateral projection which contacts the projecting lug 97 and serves in connection with the helical spring 99 to actuate the fingers. The spring is mounted upon the end of the rock-shaft, with its outer end fixed thereto and movable therewith, while its opposite or inner end is held relatively stationary by its engagement with the upper surface of the slide-bar 82. ln its form and arrangement, the spring normally tends to downwardly urge the fingers fiXed upon the rock-shaft, which downward movement is limited by the engagement of the stops 100 and 101, respectively formed upon the bearing 83 and the hub of the adjacent relatively movable iinger S5. As positioned by the stops and the action of the spring, as indicated in the drawings, the lower ends of the fingers extend vertically downward for their engagement with the strips of cardboard, and, in effecting the forward movement of the latter, pass through short longitudinal clearance-slots 102, formed through the adjacent portions of the collector-plates. As fed by the finger, the transversely positioned strips of material are jointly advanced for engagement by the presser-wheels 24, the leading edges of the strips being directed thereto by suitably arranged guide-bars 103, formed on said plates or supported relative therewith.

n operation, sheets of` cardboard or other suitable material, indicated in broken lines, are laid upon the feed-table 5 and adjusted against the lateral stop 104, from which point they are fed at regular intervals in spaced succession by the feed-dogs 42, which advance the work to the first pair of feeding-rolls 8, by means of which it is urged between the upper and lower scoring-wheels 12 and the slitting-wheels 13 to the second pair of feeding-rolls 9, the latter assisting in controlling the movement of the stock and advancing it for engagement by the glue-wheels 22 and the upper and lower set of feeding-pulleys 18. In its travel between the scoring-wheels, single and double rows of crease lines are formed upon the stock, adjacent which single lines and between which double lines, glue is applied by the glue wheels; and in its movement between the slitting-wheels, the work is longitudinally divided into strips which are severally directed to the several plates of the collector 55, in the manner heretofore described, by the tapes 57, which serve to longitudinally position the same thereon. As controlled by the feed-dogs 42, suthcient space or time is allowed between successive sheets to allow of transversely positioning or collecting the strips delivered upon the collector-plates and for advancing the strips thus collected for engagement by the presser-wheels 24, the action of the spacing- dogs 60 and 61 and the feed-fingers 85, which respectively effect these two latter movements, being suitably timed with respect to such space, so that at each revolution of the actuating mechanism, or cam-shaft 52, a new sheetis adapted to be presented to the presser-wheels. These latter wheels are preferably arranged upon their respective shafts to engage and compress the overlapping strips in line with the glued portions thereof, and where the number of strips are materially increased for the manufacture of relatively large cellcases, the upper Wheels may be severally mounted for loose rotation upon independent shafts adjustably arranged with respect to the opposite or lower set of wheels to vary the space and tension therebetween for the engagement of work of varying degrees of thickness.

n the describecl, each of the several strips of material is adapted to form one or more longitudinal and transverse cell-case members, bent along` the score lines substantially at right angles to one another, the adjacent strips being adhesively connected together at their points of bend by the lines of glue applied adjacent said score lines, as shown in Figs. 4 and 5, in which the numerals 105 formationrof the cell-case herein designate the lateral position of the score lines and 106 the relative position of the lines of glue. 'These glue lines are applied on one of each of the adjoining faces of the several strips in alternate relation with the score lines thereof, and, after being compressed and jointed together by the presserwheels, the united strips are adapted to be transversely cut up into suitable lengths and opened out to form the cell-case, shown in Fig. 5. In this latter view, the transverse and longitudinal members of the cell-case are designated by reference characters corresponding with those of the separate strips shown in Fig. ai, froin which they are formed.

As thus constructed, it will be obvious that the machine may be arranged toform cell-cases having various numbers of cells.
