BOX-BINDING MACHINERY.

SPECIFICATION forming part of Letters Patent'No. 431,249, dated July 1, 1890. Application {fled October 23,1889. Serial No. 327,953. (No model.)

To all whom it may concern;

Be it known that I, JEREMIAH E. CHAPMAN, a citizen of the United States, residing at Plymouth, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in Box-Binding Machinery, of which the following is a specification.

This invention relates more especially to forming and attaching tin fastenings or binders to butter-boxes.

The object of the invention is to provide a machine capable of cutting off pieces of tin or other metal from a strip of any Width, and then bending and pressing the same upon the articles to be thus fastened; and the invention consists of the novel devices fully set forth in the following specification and claims and clearly illustrated in the accompanying drawings, forming an inseparable part thereof, of which Figure 1 represents the complete machine in front elevation, Fig. 2 being a general plan view of same. Fig. 3 is a broken elevation of one side of the machine. Fig. 4 is a broken view showing a portion of the opposite side, partly in elevationand partly in section. Fig. 5 is a detached perspective View of the automatically-adjustable clamps, which receive and bear upon the pieces of metal after they have been bent and carry them successively to their position under the press; Fig. 6 is an inverted plan of the rotary disk upon which the adjustable clamps are mounted, showing ratch et-teeth upon its hub or journal, and its operating-crank with its hub in section, displaying a spring-pawl for engaging the ratchet-teeth of said disk. Fig. 7 is an enlarged broken sectional View of the cutting, bending, clamping, and pressing mechanism as seen when in a position ready to cut and bend a piece of metal. Fig. 8 is a similar view of the same parts as when one of the pieces of metal has been cut off, bent, and carried under one of the adjustable clamps. Fig. 9 is a detached plan view of that style of guide which is illustrated in cross-section in Figs. 7 and 8, into or against which the metal strip must rest while being cut off, and Fig. 10 is a plan taken 011 line Y Y, Fig. 7, in which a modified form of block P is shown.

Similar reference-letters designate corresponding parts throughout the various views.

A is the m achine-frame, provided with bearings a for carrying the power-driven shaft B, bearings a, carrying a counter-shaft B, and bearings a carrying the shaft B having one end in connection with the shaft B by the bevel-gears Z) b, respectively, and its other end in connection with the shaft B by the bevel-gears 19 17 respectively. A rotary disk 0 is depressed in the bed portion of the frame Ain a horizontal position, and upon its under side is a journal 0, which passes through and below the said bed portion of the frame A. Various means may be employed to revolve this disk, one of which is shown in the drawings, to wit: The projecting portion of the journal 0 may be provided with ratchet-teeth c, as seen in Fig. 6, and upon this is mounted a crank D, carrying a suitable spring-pawl d for engaging the ratchet-teeth c, said crank being operated in one direction by means of a rod D, connecting said crank with one end of a movable rack E, suitably mounted in the bed portion of said frame A and adapted to be moved by the sectional gear E, carried upon the counter-shaft B, as seen in Fig. 2, and in the opposite direction by means of a suitable spring, as seen at E in Fig. 3 and in dotted lines, Fig. 2.

The disk 0 has a portion of its upper surface elevated, as at C, and in plan view this may be square, as in Fig. 10, and upon this are mounted automatically-ad j ustable clamps F, constructed and placed one upon the other in the manner seen in Fig. 5. Each of these are provided with an elongated opening f in their longitudinal center for the reception of the screw G, which passes down and is threaded to an opening 0 provided for the purpose in said disk 0. Studs c are also provided upon the portion 0' of said disk for guiding and retaining the said clamps in their proper position laterally, anda helical spring 9, placed upon the screw G in a manner to operate eXpansively between its head and one of said clamps F, will cause sufficient friction between themselves and the said disk to properly regulate their legitimate motion.

The part A of the frame A partially incloses a cam or eccentric H, mounted upon cut.

the front end of the shaft B, having a connecting-rod I, which is attached or pivoted to a plunger J which presses the pieces of metal lupon the articles they are to fasten, after the same has been cut and bent, as will be presently explained.

Upon that side of the part A of the frame nearest the shaft 13' are provided adjustable ways K, having grooves in their adjacent sides to receiveastrip of metal L, from which the pieces which are to form the binders are These ways are secured by screws, which pass through slots 75, formed laterally at intervals therein, in order that they may readily accommodate themselves to strips L of various widths.

The bending mechanism consists of a flat bar M, dovetailed within a groove a formed in the bed portion of the frame A and provided with an upward projection m, a cam M, mounted on the counter-shaft B, which by contact with said projection m moves said bar the required distance to bend the piece of metal Z, and a suitable spring m, connecting said bar with the machine'frame in a manner to cause the former to return after each movement occasioned by the said cam to its normal position.

The cutting mechanism consists of a bar N, dovetailed within a groove formed for the purpose in the said bender M, and provided with an upward projection n, a cam N, mounted on the counter-shaft B, which by contact with said projection moves the cutter to its work, and a suitable spring n, connecting said cutter with the machine-frame and adapted to return the former to its normal position after having out off one of the pieces of metal Z. A bed-guide or cutting-block P has a cutting-edge 19, against which the strip of metal L rests while the cutter isperforming its work, and screws 19' will secure the said block in its proper position. The under side of said block P is formed on an incline from the said cutting-edge to its bottom, and the bed portion of the frame of the machine is formed on an opposite incline, thus forming an inclined passage Q, in which the pieces Z become sufficiently bent by the bender to enter their final resting-place R, formed between the disk (1 and either of the clamps F. The upper parts of each end of these clamps F are beveled, as shown, and the back side of the under portion of the presser-bar or plunger J is likewise beveled, as at j, (seen in Fig. 3,) so that the downward movement of the latter first movesa clamp back sufficiently to uncover a piece Z while resting, as seen in Fig. 10, upon the disk 0, and then spends its force upon the said piece or binder Z.

A balance or belt pulley S is mounted upon the shaft B, from which motion and power are communicated to the mechanism hereinbefore described. I It may be here mentioned that the cam driving the cutter may be so placed upon the counter-shaft B and so formed as to cause the cutter to cut the metal L and rest in the position shown in Fig. 8, while the bender M passes forward and returns, when the metal L may again drop to the position shown in Fig. 7.

The operation of the machine is very simple. As each piece of metal or binder lis cut from the strip L the bender M is caused. to strike it in its center and force its way through the passage Q and into the chamber R, where it lodges until the disk 0 is rotated one quarter of a revolution, or to a position directly underneath the presser-bar J, and while another binder l is being carried under the other clamp F the boxes or other articles to be bound or fastened by the said binders are placed within the binder, then at the front of the machine, and the presser-bar J descends, driving the clamp back, as seen in Fig. 10, and fastening the binder to the article, as desired. Each clamp F is pushed back in this manner successively by the presser-bar J thus setting their opposite end in proper position to form the pocket or chamber R for receiving the binder Z. The movement of the disk 0 is intermittent, its motion being arrested when one of the clamps reaches a point opposite to the cutter and bender and the other directly underneath the presserbar. The reciprocal bender M also serves as a means for feeding the binders Z to the intermittent rotative table or disk 0 and its automatically-adj ustable clamps.

Having described my improvements, what I claim as new is 1. In a metal cutting and forming machine, the combination, with suitable cutting, bending, and binding mechanism, substantially as described, of an intermittingly-rotative table or disk and automatically-adjustable clamps mounted thereon, substantially for the.purpose set forth.

2. The combination of an intermittinglyrotative table or disk, two or more automatically-adjustable clamps mounted thereon, a

reciprocal cutter, a reciprocal bender, their driving mechanism, and a presser-bar, ,all substantially for the purpose described.

3. In a metal cutting and forming machine, the combination, with a suitable supportingframe, of an intermittingly-rotative table or disk, two or more automatically-adjustable clamps mounted thereon, having their ends beveled, suitable cutting and bending mechanism, and a presser-bar having one edge beveled, all substantially for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JEREMIAH E. CHAPMAN.
