SPECIFICATION forming part of Letters Patent No. 588,434, dated August 1'7, 1 897. ApplicationfiledSeptember28,1896. Serial No. 607,150. (No model.)

To all whom it may concern:

Be it known that I, WARREN B. HOWE, of Chicago, in thecounty of' Cook and State of Illinois, have invented certain new and useful Improvements in Pasting-Machines; and

I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines intended for fastening together by adhesive materials the blanks or parts of paper or strawboard boxes or cartons; and the object of the invention is to enable the work of supplying adhesivematerial and the placing together of the blanks to be carried on with rapidity and with perfect accuracy in the finished work.

The invention consists in the matters hereinafter described, and pointed outin the ap-' pended claims.

The machine herein shown embraces as its main or principal features a tubular blankholder, which acts as a support or guide for the blanks at the time the adhesive material is being applied thereto and to hold the parts of the box in proper relative position While drying, and a paste-applying device movable periodically into contact with the blanks resting in the tubular holder and acting to apply adhesivematerial to the blanks asthe latter are placed successively in the holder by hand.

A machine embodying my invention is ap plicable in the manufacture of boxes of any kind which are capable of being folded flat at the time the paste is applied, the same being more especially adapted for use in the making of what are known as knockdown boxes. The machine herein shown is, however, more especially designed for the making of cartons, such as are used for packing candy and other articles inbarrels or-pails and which consist of a plurality of sectorshaped cells or compartments formed by radial walls connected at their outer ends by equal and similar sections adapted to fold upon their lines of juncture With each other simultaneously with the folding together of of the adjustable guides in the blank-holder,

showing the arrangement of the spring-retarding arms. Fig. is a horizontal sectional View of theparts shown in Fig. 3, taken on the line 4 4. thereof. Fig. 5 is a planview of the machine with the power-applying mechanism and a portion of the link broken away. Fig. 6 is a vertical section taken through the paste receptacle and reservoir and through the paste-carrier on the line 6 6 of Fig. 5.. Fig. 7 is a vertical section of the mechanism, taken on the line 7 7 of Fig. 5. Fig. 8 is a detached sectional view of the compressible link with its spring removed. Fig. 9 is a horizontal sectional view of the blank-holder, paste-carrier, and paste receptacle and reservoir on the line 9 9 of Fig. 5 and showing the paste-carrier in different positions. Fig. 10 is a view of the carton after the paste has been applied by the machine with some of the compartments opened. Fig. ll is avieW similar to Fig. 2, showing a portion of the machine, but with the adjustable plates of the paste-carrier and of the blank-holder arranged for pasting a different-shaped box.

The machineis shown as mounted on a table consisting of a horizontal top A and four legs attached thereto. A rectangular portion A extends laterally from the table-top and supports a standard A in which is j ournaled a shaft B, which has rigidly fastened to its right-hand end an ordinary belt-Wheel B and on its left-hand end a gear-pinion B which meshes with a gear-wheel O, rigidly and centrally fastened to a shaft 0, which is journaled at its right-hand end in a bearingin the standard A directly above the bearing for the shaft B. The shaft 0 is also journaled in a bearing in the curved stand ardA projecting up wardly and forwardly from the rear of the table A, and carries at its left-hand end a crank C to which is pivoted a connecting rod or link, shown as consisting of two parts D D, through which motion is transmitted to a swinging frame E, to which is attached the paste-carriers F, by which paste is transferred from a paste-receptacle H to the blanks held in a tubular blank-holder K. The said link, as shown, is made yielding or compressible lengthwise, and for this purpose consists of the screw threaded eyebolt D, which can slide to a limited extent in the tubular socket D, which is pivoted at its forward end between two cars E on the swinging frame E. The socket D has a slot D in its upper surface, in which plays a pin D projecting upwardly from the forward end of the bolt D, as clearly shown in Figs. 7 and S. A strong helically-coiled spring D surrounding the bolt D, is confined between the rear end of the socket D and a nut D on the screwthreaded portion of the bolt D, which is held in place by a lock-nut D The frame E, as seen in Fig. 5, is rectangular in shape and is carried by parallel arms E pivoted thereto and projecting upwardly from the ends of a pair of parallel rock-shafts E, which are mounted on bearings carried by the lugs A on the table. These rock-shafts E might be journaled directly in the lugs, but I prefer to have bearing-cavities in their ends,with which cooperate the ends (shown as conical) of bolts E inserted through the lugs A and held by the lock-nuts at any desired adjustment. It will be readily seen from this construction that when the shaft C is rotated, the bolt D and the socket D ordinarily operate as a rigid link, and the frame E will be carried back and forth from the two extreme positions shown in Figs. 8 and 9.

The forward portion of the frame E has rigidly fastened to the under side or integral therewith, as shown, the rectangular plate E containing the parallel longitudinal slots E (best shown in Fig. 5,) by which the pastecarriers are secured to said frame. These paste-carriers, as seen in Figs. 5 and (3, consist of plates F, which are rectangular in plan view, but of L shape in cross-sectional form, and in the downwardly-projecting portion or flanges of the plates are fastened two parallel rows of paste-applying pins F. Said pins are .brought into contact with or have their ends immersed in the adhesive material in the paste-receptacle at each backward movement of the paste-carriers and are brought into contact with or pressed against the blanks, so as to deposit on the blank the material which adheres to their ends, somewhat as ink is deposited from type in printing.

The proper angular adjustment of the plates F on the frame E is elfected as desired by screws F which pass through the slots E and enter the top of the plates F, so as to hold them in any desired position. In the machine here illustrated it is desired to have the paste applied on the portions of the box where the laps G of one portion come against the ends of the .radial parts G of the adjacent portion, as shown in Fig. 10. As the portions or blanks which form the carton are not rectangular, but are irregular in their shape, as shown in Fig. 5, the two brushplates F are set at an angle to each other, as seen in said figure and as more clearly shown by the spots upon the folded boxes, showing where the paste has been applied.

The pins F at each rearward movement of the frame E are thrust into the paste-receptacle H a fixed dept-h. As it is desirable that the pins shall always take up the same quantity of paste, it is necessary that the pastereceptaele always be filled to a uniform depth, and this condition is attained by the following mechanism:

The paste-receptacle H is located above the level of the paste-reservoir H said receptacle, as herein shown, being mounted upon posts H,resting upon the bottom of the pastereservoir, which has the form of a shallow rectangulartank. Said reservoir, as shown in Fig. 5, rests by means of posts H upon the top of the table. Journaled in the righthand end of the reservoir 11 is a horizontal shaft 11*, which has secured to its right-hand end abelt-wheel 11, through which said shaft is driven by means of a belt J from a similar belt-wheel C fastened on the shaft 0. To the left-hand or inner end of the shaft H is attached a disk H, thelower portion of which is immersed in the paste in the reservoir II", as shown in Fig. 6. The paste-receptacle H 'is rectangular in shape, as seen from above,

except that it has a rectangular offset portion H at the rear portion of its right-hand end, said offset portion bearing at its end against a portion of one side of the disk H It results from this construction that as the disk H is rotated and passes into the paste it will carry up the paste which adheres to it, and the adhering paste will be scraped off by the edge of the receptacle II and will flow into the said receptacle asthe rotation continues, thus keeping the receptacle constantly full to overflowing, the disk H carryingupwardly and depositing the paste faster than it is removed by the paste-carrier.

To the forward end of the table A is secured the blank-holder K, which is substantially rectangular in plan view and contains within it adj ustable guide bars or strips, whereby its bearing-surfaces, which engage the edges of the blanks, may be shaped so as to accommodate blanks of any desired form. The vertical rear wall K of thetubular holder has a cross-section of the shape shown in Fig. 5 and carries two guide-strips, the first of which, L, is not adjustable, but is substantially rigid with the right-hand side of the rear wall K. The second strip L on said wall K is adjustable by means of set-screws or bolts L (shown in dotted lines in Fig. 5,) passing through the slots K in the rear wall K and entering said st-rip L. This strip L is shown as adjusted to difierent positions in .Figs. 2 and 11.

The right-hand side wall K has no adjustable strips; but a raised strip K furnishes a smooth flat surface against which the edges of the blanks rest and by which they are guided on this side, as shown in Fig. 5. The left-hand side wall K has mounted thereon a guide-strip L of the cross-sectional form shown in Fig. 5 and adjustable inwardly and outwardly by means of set-screws L which engage screw-threaded holes therein and pass through screw-threaded lugs in the wall K The front wall K has mounted therein a supplemental wall K, having a cross-section as shown in Fig. 5 and adjustable backwardly and forwardly by means of thumb-nuts K on I screw-threaded bolts K which are fastened to the right and left hand ends of the wall K The supplemental wall K has at its righthand end a raised portion or strip K furnishing a flat guide-surface for the blanks, and at its center is an adjustable strip L similar to the strip L, similarly mounted and adjusted and acting to guide the blanks, as shown in Fig. 5 It will be seen that bythis construction of the holder K, as hereinbefore described, I have obtained a structure that guides the blanks of the shape illustrated through it without allowing any shifting from the position first assumed, and also one that is capable of being adjusted so as to accommodate blanks of very different shapes.

"To prevent the blanks from passing through the holder K without any resistance and to yieldingly detain them at the bottom so that in operation the holder will always be full and those at the top will remain in proper position for the action of the paste-carrier thereon and offer sufficient resistance to the pressure of the paste-applying device to insure proper application of the paste thereto, I place in the lower end of the holder spring arms or detents M, adapted to stand normally in position to resist the downward movement of the lowermost blanks in the chute, but

adapted to yield outwardly under downward a downward inclination into the tubular holder. Each spring rests in avertical groove or recess m, adapted to receive its lower end when thrust outwardly.

The means shown for attaching the springs to the guides consist of slots m, Fig. 3,

The blanks approach the lower end of the I holder K, and meet with considerable resistance to their further progress from the springdetents, which is overcome by the weight of those above them and the pressure of the paste-applying device acting thereon. As vthey are finally forced out at the bottom, the lug M offering more resistance than is experienced at any other side, the box is .released from that side last, so that it falls always in one position, as shown in Fig. 9.

While I have herein called the device for I holding and guiding the blanks a tubular blank-holder, yet it is to be understood that the essential parts of such holder are the guides or guide-strips themselves, and the holder may be of skeleton form or consist of guides supported in any suitable way and need not be tubular in the sense of being a closed tube, and which latter form of holder is herein shown merely as a matter of convenience in construction.

The carton, which the machine illustrated is more especially intended to make, is shown in Fig. 10, the same consisting of a plurality of radial partitions G G, each adjacent pair of which are connected by two are walls G G flexibly joined to the radial walls and to each other at a point midway between the radial walls, so that the cell formed by the two radial walls and the two are walls may be folded fiat by the outward folding of the arc walls on their lines of juncture and the bringingof the radial walls into contact ,with each other, as clearly seen in Fig. 10. The carton thus constructed is composed of a plurality of separate pieces, each of which forms one radial wall G and two are walls G2 G and which is provided at its ends with flaps G G forming extensions of the inner end of the radial wall and the extremity of the arc wall, so that when the said flaps are pasted to the outer faces of the radial walls of similar blanks a series of compartments will be formed, as clearly seen in said Fig. 10.

All 'of the compartments necessary to constitute a circular or segmental carton will be made by the use of like blanks, with the exception that the end compartment of the series will be finished by means of a fiat blank G equal in length to a radial wall only and which when the carton is expanded will rest against the radial wall at the opposite end thereof, as clearly seen in dotted lines in said Fig. 10. The blanks forming the carton of the kind described are joined when in their collapsed or folded position by applying the adhesive material to the flaps G G or to the marginal parts of the arc walls against which said flaps rest and piling the blanks one upon another with their edges accurately in register. In thus piling the blanks the number used for each carton is equal to the number of cells in the carton, and a single blank to form the radial wall G is then applied to complete the final or terminal cell, when the carton will be finished in knockdown form and may be readily expanded into its circular form. The construction of such a carton is more fully explained in the prior patent granted to F. B. Davidson February 5, 1895,

In the operation of the machine the operator stands in front of it and has in a convenient position a supply of the two kinds of blanks above referred to-namely, the blanks forming the walls G G and the shorter blank for forming the wall G These blanks will conveniently be placed on extensions A of the table, Fig. 5, which are located at either side of the front of the machine. Assuming the blank-holder K to be filled with previously pasted and folded blanks, or with a suitablyshaped filling piece or block to support the first blanks, the operator first takes a short blank and lays it on top of the pile between the upper ends of the guide-strips K K, L, L, L and L The machine is then started and the paste-carrier moved from the pastereceptacle into contact with the blanks, against the upper surface of which the pasteapplying pins are pressed, so as to leave an imprint of paste thereon,- the paste being applied in a line at either end of the blank. The action of the paste-carrier serves also to press the entire pile of pasted blanks downwardly a short distance through the guides. One of the longer blanks is then folded by the operator into the form shown in Fig. 10, the flap G being folded against the adjacent radial wall, while the flap G is left in the same plane with the outer portion of the are wall, to which it is attached. The folded blank is then placed in position on top of the pile between the guide-strips, thereby bringing the two flaps G and G3 against the pasted portions of the shorter blank. The blank is so placed on the pile during the time the paste-carrier is moving toward the pastereceptacle and returning therefrom, and in the subsequent advance of the said paste-carrier the latter applies paste to the top surface of the longer blank at the inner and outer margins of the radial wall thereof. A second long blank is then folded and placed on the first long blank, and these operations are re peated until the number of blanks added to the pile equal the number of cells in the carton. The carton shown in the accompanying drawings, Fig. 10, is provided with five of such cells, and consequently consists of five of the longer or folded blanks and one short blank. After the carton has thus been completed a new carton is started by placing a short blank on top of the pile without permitting any paste to he applied to the last blank of the completed carton. This may be done by placing a folded blank and a short blank together on the pile, or by interrupting the action of the paste-carrier long enough to add the short blank, this being done by pressing down the treadle N, which throws the hook N upward into position to act on the rear cross-bar of the frame E, as seen in Fig. 2. The resistance offered to the descent of the lowermost pasted blank in the pile,

combined with the weight of the superposed blanks and the pressure of the paste-carrier thereon in applying the paste, insures that the paste-pots shall be kept closely pressed together until the parts sufiiciently adhere or the paste is dried.

As above stated, the construction of the blank-holder permits the same to be employed in the making of boxes of various shapes, and the paste-carriers F being adjustable in position on the swinging frame the same may be arranged to apply the adhesive material to any portion of the blanks desired, as made necessary by reason of the shape or construction of the box.

In Fig. 11 of the accompanying drawings I have shown the adjustable guides of the blank-holder and the paste-carriers as arranged to operate on a box-blank of rectangular form.

While my invention is herein shown as embodied in a machine adapted for pasting cartons of the particular form shown, yet it is to be understood that it may be applied to operate on boxes of different shapes and that the details of construction in the machine may be greatly modified without departure from the spirit of the invention. I do not, therefore, desire that my invention be limited to the exact form or details of construction in the machine shown and described, except so far as the features of said machine maybe set forth in the appended claims.
