SPECIFICATION forming part of Letters Patent No. 347,999, dated August 24, 1886.

Application filed June 8, 1885. Serial No. 167,951. (No model.)

To aZZ whom, it may concern.-

Be it known that I, ANDREW MURRAY EASTMAN, of Milford, in the county oHVorcester and State of Massachusetts, have invented 5 certain new and useful Improvements in Mmchines for Covering thc'Exteriors of Paper.

Heretofore in the manufacture of paper have been covered to the second machinc' 2 causes a great disadvantage, which is entirely overcome by my present invention, which consists in a machine containing certain novel features of construction and arrangements of parts by which the sides and bottom of a box,

2 or the side and top of a cover, may be overlaid with paper without removing the box from the form, all as will be fully understood by reference to the description of the drawings and to the claims to be hereinafter-given.

Of the drawings, Figure 1 represents a perspective view of a machine embodying my invention, looking at the front or operating end thereof. Fig. 2 represents a side elevation of the same. Fig. 3 represents a transverse sec- 5 tional elevation ofthe same,lookingtoward the rear of the machine, the cuttingplane being on line 00 m on Fig. 2. Fig. 4 represents a central longitudinal sectional elevation through the box form or block and its operating device. Fig. 5 represents a sectional plan of the same, the cutting-plane being on line 3 g on Fig. 4. Figs. 6 and 7 represent details of construction of the same, which will be more fully described further along in the specification. 5 Fig. 8 represents a plan of the cutting-off device. Fig.9 represents a sectional elevation of the same, the cutting-plane being on line 2 z on Fig. 8. Fig. 10 represents a section through the upper shear-blade of the same, and the cam-lever by which it is operated.

Fig. 11 represents a section through various portions of the frame, showing in elevation the device for stopping the form at the end of its revolution. Figs. 12 and 13 represent dctails of construction of the same, which will v be further described subsequently. Figs. 14,

15, and 16 represent details of construction of the paste-scraping device, which will be fully described further on. Figs. 4, 5, 8, 9, 11, 12, 13, 14,15, and 16 are drawn to an enlarged scale, while Figs. 6, 7, and 10 are drawn to a still larger scale.

In Fig. 1 the box is represented to be upon the form with the paper pasted thereon before the cutting-off has been completed, while 6 in the remaining views the paper is represented as having been cut off and the box re moved from the form.

In the drawings, A represents the frame of the machine, upon the rear end of which are mounted the shafts a a in suitable bearings, said shafts a (1. having scoured thereto rc-- spcctively the spools bl), each carrying a roll of paper, B B, the strip of paper composing the upper roll, B, being used to cover the tops of the covers and the bottoms of the boxes, while the paper composing the lower roll, B, is used for the sides of the same.

Immediately in front of the rolls B B and between the upper side rails of the frame .A is '8c secured a paste trough or box, 0, which is partially filled with paste or any other suitable adhesive material, into which the paste-r0110 is partly submerged, so that as it revolves about the axis of the shaft 0 mounted upon the upper side rails of the frame A, the entire periphery of said roll is covered with a thin film of paste, which is transferred to the under side of the strips of paper as they pass over the said roll after having passed beneath the 0 small roll d, which intervenes between said paste-roll O and the spools b b. In order that either strip of paper may move independently of or without in any way interfering with the other, the rolls 0 and d are each divided transversely into two parts, so that either part may revolve upon its shaft without moving its fellow. Directly in front of the center of the paste-roll is mounted in bearings on said up-' per rail a small shaft, 0, under which the paper passes on its way from the paste-roll G to the scrapers E E,\vhich are secured to said upper rail of the frame by suitable feet. The paste-scraping device E or consists of a foot, 0, by which it is adjustably secured to said top rail of the frame, and from which projects a lag, e, at right angles thereto. This lug e is provided with a suitable bearing, in which is mounted the arm 0', in which is fixed at right angles thereto the stud e", upon which is mounted the' L] shaped bar 6 and the roll 6 between the arms of said bar. The arm 6" may be secured by the thumb screw 6, so that the roll 6 will be at any desired angle with the top of said machine for the purpose of properly directing the paper to the form D. The arm e, moreover,vis provided with a number of apertures. e 0', corresponding in size to,

and at the same distance from the center of the stud e" as a single hole in the lower arm of the scraper-bare, by which, with the pin re, the said bar may be secured at any desired angle, so that the paper in passing from beneath the roll e over the top of the bar e will bed rawn over at a greater or less angle, according to the consistency ofthe paste and the quantity thereof it is desired to have remain upon the paper, all asis shown in Figs. 14, 15, and 16. All the paste'whic'h drops from the bars e c, after having been scraped from the strip of paper, is caught by the dripping-pan F, resting on the central side rails of the frame.

To the front end of the machine and on either side thereof are secured the paper supporting arms f f, by which the strips of paper are guided to the form D, said arms being mounted upon suitable feet, f f, provided with slots, by which and suitable thumb-screws they are secured to thefront legs of the frame in such a manner that the said arms may be adjusted to any desired angle or height. These arms ff also serve to hold the ends of the strips of paper when they have been cut or broken off in a position in which they may readily be grasped to repeat the operation of j The central horizontal side rails extend some distance be I yond the front uprights of the frame, as shown at g g, and to the under sides of these extensions is secured the shelf upon which is mounted the form D, which consists of a stand, h, firmly secured to the shelf 9, and provided I- with suitable bearings, in which the tubular? shaft h may be mounted parallel to the front covering upon a succeeding box.

of the machine and at about an angle of fortyfive degrees with saidshelf all as shown in Figs. 1, 2, and 3. To the outer or upper end of this tubular shaft is firmly secured the support If, having four arms, If h, each of which is provided with a raised boss, h, against which is firmly screwed the plate W, as shown in Fig. 6, between which and said support h are placed the upper plate of the four cornersections h h" h h, each of which is provided with a diagonalslot, h, by which said cornersection'is guided toward and from the center of said form. Each side of the corner-pieces u v v 345,999

h h h h is provided with two holes therein .the said corner-pieces as tar as possible from the center of said form, so that at all times they will tend to have the greatest perimeter. The corner-pieces h h h h are provided upon their outer edges with a rib, h, extending to the same height as the upper surface of the plate b In order to stiflen the form D and cause the corner-sections h h h h to move toward and from each other. a rod, h, is placed within each ofthe coiled springs h of a length equal to the length of said spring minus the distance between said corner-pieces.

To the inside of each of the corner-pieces h is pivoted a toggle-link, t, of alength somewhat greater than the distance from said pivot to the tubular shaft h, upon whichshaft is mo'u'nted a four-armed collar,'t", to which the other ends of the links i i i i are pivoted, and

which is connected by a suitable pin passing through slots in said tubular shaft to a rod, 0', mounted within said tubular shaft h in such a manner that it can be reciprocated therein by the handle 5, pivoted at if to a stand secu red to said tubular shaft h for the pn rpose of compressing the springs h h when it is desired to place a box upon the form or remove one therefrom. The handle i passes through slots in both the tubular shaft h and the rod 1', but is only connected to the rod by a screw, i, which may be removed and the handle a" slipped along in the slot in said rod and connected'by the same screw at another point, as at i t", for the purpose of regulating the size of the form D. By these adjustments a large a number of sizes and slightly-varying forms of boxes may be covered upon the same form; but when an extreme size or radically different form of box is desired to be covered it will be necessary to place upon the machine a larger, smaller, or differently-shaped form, as the case may be.

The construction and working of the form D will be readily understood 'by reference to Figs.4, 5, '6, and 7.

To the lower end of the tubular shaft h is firmly secured the bevel gearwheel k, by which the form D is rotated about its axis, motion being imparted thereto for the purpose by the bevel gear-wheel k, mounted, together with the cam-disk k and pulley k, upon a short horihas inounted on the outer end thereof thepul-j ley k by which said shaft is is continually re-; volved. The shaft 7; is also provided with a suitable friction-clutch, preferably composed! of the loose pulley k and the disk is, having interposed between them the disk of leather. it; but any othersuitable clutch could be used. The loose pulley k is provided with agrooved hub, in which the lugs ZZ upon the inner-sides of the slotted arm Z, pivoted at Z to the under side of the front lower cross-rail of the frame, engage in such a manner that the pulley may readily be moved from or against the leather disk is". The outer end of the arm Z passes through the slot Z in the cam plate Z,mounted upon the rod P, the upper end of which passes through the shelf 9 and bears against the periphery of the cam-disk said rod being retained in this position by the tension of the spring Z", coiled around it between said plate Z" and the guide-plate Z, secured to the under side of the rail i To the lower end of the rod Z is secured the treadle G, pivoted at m to the pendent arm at, secured to the front cross-rail of the frame of the machine. The cam-disk 75" is provided in its periphery with a notch, a, somewhat larger than the end of the rod Z said notch a engaging with the end of said rod Z when the form is in a position ready to revolve for the par pose of covering the sides of the box placed upon the said form. Alter the form D has made a complete revolution the notch it again comes to a position above the end of the rod Z when the tension of the spring Z will cause the rod Z" to be raised so that the end thereof will engage with said notch and pre vent any further rotation of the form D, while at the same time the cam-plate Z is raised with said rod Z so that the arm Z is moved away from the said rod, so-thatthe loose pulley k is disengaged from the disks k and It", thus preventiugany further motive power being transmitted to the pulley k" to cause the form D to be rotated.

In order that the form may be stopped in a position somewhat inclined to the shelf 9, the aperture in said shelf, through which saidrod Z passes, is made somewhat elongated in the direction of the length of the machine, and above this is placed a plate, a, in which the hole a nicelylits the squared end of therod P, for which it formsa bearing. This plate a is adjustably secured to the shelf g by the screwbolts a a passing through the slots a n therein, so that the point at which the notch a will engage with the end of the rod Z may be nicely adjusted from a point on one side of the center of the cam-disk 76- to a point on the other side of said center, thus allowing the rear end of said form D to stop at a position at various distances from the shelf 9, as may be desired, all as shown in Figs. 3, 11, 12, and 13.

Upon the end of the shaft is, opposite to the pulley k is secured one half, 0, of a clutch, the other half, 0, of which is loosely mounted upon the end of said shaft and is provided with an annular groove, with which the forked arms 0 0" on the rod 0, mounted in suitable hearings on the lower side rail of the frame, engage said rod 0 being provided with an other arm, 0, bent nearly at right angles thereto and reaching nearly to the floor, by the operator moving his foot, against which the clutch 0 0 will be engaged,and the arm 0 forming a part of the outer half thereof, will be caused to be rotated with said shaft in, by which rotation the chaiup, one end of which is secured to the end of said arm, is caused to be pulled downward over the sheavep' and cause the blade p to be moved forward in its grooved track the opposite end of said chain being secured to the pin p, mounted in the end of said blade 12 In asuitablebearingin the bladepis loosely mounted the shaft f, upon which is firmly secured, so as to revolve therewith, the spu r-pin ions p p 'and the eann-armp, and said shaft also has loosely mounted thereon the upper blade, 1), provided on its outer end with the weight 1)", and between said weight and the shaft 12'' is secured thereto the cam shoulder or lug 10 onthe same side of said blade as the cam-arm 1f is situated. The ends of the shaft p find suitable bearings therefor in the slots (1 (1, extending nearly the entire length of the side walls or upright plates, q q, of the frame g", which frame is also provided ,just within said side walls, q q, with two racks, q, with which the pinions p p engage, which causes the shaft 9 to rotate about its axis whenever the shear-blade p is moved forward or backward.

The operation of the cuttiug-offdevice is as follows: The parts thereof being in the positions shown in Fig. 3, and the paper for the bottom of the box having been attached to the outer end thereof, the operator places his foot against the rod 0* and presses the lower end thereof to the left, so that the rod 0 is rotated in its bearings, moving, through the agency of the arms 0 0", the loose haltl o of the clutch into engagement with the fixed half 0 thereof, so that the arm 0 will be moved from its highest to its lowest position, thereby pulling down upon the chain 12 and causing the blades fp to move forward, one on either side of the'paper to be cut, the frame q and the paper being adjusted so as to correspond in inclination. The blades 1) p are so mounted on the shaft 1) that if at this time by any chance they should come together, owing to their looseness, they would be unable to cut the paper; but when the paper is wholly between said blades 1) p the canrarm p has almost completed a revolution, and comes into contact with the cam shoulder or lug p The inclined surface r of the arm p pressing against the inclined surface upon the shoulder p forces the lower ends of the blades p p apart, so that as the arm p continues to revolve, and coming in Contact with the inner lower side of said shoulder 12", secured to the blade p lifts the lower end of that blade, and thereby causes the upper end to move downward past the bladep. The knife-edges r r on said outer ends are pressed firmly together while passing, so that wet or damp paper may be cut with great facility. The cutting of the paper having been accomplished, the foot of the operator is removed from contact with the arm thus allowing the clutch o 0' to become disengaged, and the blades p to regain their normal positions, as shown in Fig. 3, by their preponderance of weight over the chain and other parts.

In order to always out off the paper used for the bottoms of the boxes at the right point when different lengths of boxes are being covered, it is necessary that the frame q should be made adjustable upon the frame H, which is accomplished by fitting said frame qso that it will readily slide between the ribs or guides s s, and may be held in any desired position by the clamps s s, the sheave p being loosely mounted upon its shaft so as to be moved therewith. The frame H is secured by suitable feet to one of the rails gat an angle of about forty-five degrees, all as shown in Fig.

3. This same mechanism for cutting off the paper may be repeated, if necessary, on the opposite side of the machine for the purpose of cutting off the paper with whichthe sides of the box are covered; but for general use in this case I consider it as well to tear off the paper over the edge of the box by the hand of the operator; but for. the tops of covers and bottoms of boxes this could not be neatly done, and therefore in such cases the cuttingofl' mechanism is necessery.

To the supporting-arm f isadjustably secured,by the thumb-screw f ,the rod f which passes over the strip of paper B in order to prevent its being thrown out of place by the rotation of the form D.

The operation is as follows: The parts of the machine and the strips of paper being in the position 'shown in Figs. 2 and 3, andthe' end of the rod 2 entering the notch n of the cam-wheel k", the operator moves the handle 1' downward,'thereby causing the springs h h to be compressed so as to allow-the cornersections h h to come together, so that the box may be readily placed thereon,which having been accomplished the operator looses his hold upon the handle 1, thus allowing thecorner-pieces h h toexpand, so that the perimeter thereof corresponds with the interior perimeter of the said box. The operator then takes the end of the strip of paper B, and se-,

cures it by means of the paste'upon its under side to the front edge of the upper side of the box, and then places his foot upon the treadle G and presses down thereon, thereby causing the form D to revolve toward the operator, who, meanwhile, by means of a suitable pad or his hand presses the paper down upon the sides of the box, so that it is firmly secured thereto upon its entire surface. The paper having been wrapped around the entire perimeter'of the box, and the form D having been stopped in the manner already described, the paper secured to the box is severed by the hand of the operator or by a cutting-off device from that remaining, which is held up by the supporting-arm f in a position where it may readily be grasped at the commence ment of the covering of the next succeeding box. The sides of the box having thus been covered the operator seizes the end of the strip of paper B, and secures the same to the front edge of the bottom of the box, after which he operates the cutting-off device with hisfoot, as has already been described, and then with his hand or a suitable pad smooths the cut-off portion down upon the bottom of the box, so that said paper will adhere in every part to said bottom. This having been completed, the operator again presses upon the handle i, so as to release all pressure upon the box, so that it may be readily removed, and another placed in position in order to repeat the operation.

It is obvious that a cover may be overlaid with paper in the same manner as is used to cover the box.

The peculiar advantages of a machine of this construction, by which both the sides and the bottom of a box are covered without necessitating the removal thereof from the form, are so perfectly obvious that further comment thereon is deemed entirely unnecessary.

The papersevering mechanism shown and described but not claimed in this application .forms the basis of and is claimed in another (or nearly so) to a perpendicular, and two paper-guides inclined at asimilar angle but in opposite directions, substantially as described.
