SPECIFICATION forming part of Letters Patent No. 641,876, dated J anuary 23, 1900.

Application filed April 26, 1899. Serial No. 714,501. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM G. METOALF, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in stapling-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, 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 pin-ticket machines.

The object of the invention is to provide a.

machine with a capacity for making the parts of the ticket and uniting said ticket to the fabric or other article all in one operation.

In the drawings herewith annexed, Figure 1 is a side elevation of the mechanism, the cover being removed to show nothing but the mechanism and supporting-frame; Fig. 2, a similar elevation of the opposite side to that shown in Fig. 1; Fig. 3, a top plan View, the ends of the supporting-frame appearing in section and parts of the mechanism removed; Fig. 4, a section on the line 00 x of Fig. 1 looking in the direction of the arrow; Fig. 5, a sectional view of the type-wheels and cooperating devices; Fig. 6, atop plan view of the staple mechanism; Fig. 7, an elevation of the same; Fig. 8, a bottom view of the plungerguide; Fig. 9, a plan view of the lever through which the platen of the stapling mechanism is operated; Fig. 10, a side view of the ribbon-feeding slide; Fig. 11, a side elevation of the machine; Figs. 12 and 13, different views of the staple plunger or driver; Figs. 14, 15, and 16, detail views of .the staple-depositor; Fig. 17, an enlarged elevation of a portion of the vertically-reciprocating bar and the staple-plunger; Fig. 18, an enlarged elevation of the upper end of the operating-rod and connections; Fig. 19, a detail sectional view of the staple-former.

Throughout the specification similar reference characters denote corresponding parts.

The main or primarily moving partsconsist of a horizontal bar A, movable up and down, and a parallel rock-shaft or rod B. The

former has at one end an upright tubular ex= tension A, which incloses a guide-post A, secured to the frame 0. The other end of the bar A has attached to it a staple plunger or driver a, and said bar also carries a series of type-wheels o and form a, which will be more particularly described hereinafter. The ribbon b from roll 19 passes over the stationary platen 1) below the type-wheels and form and is fed intermittently by a reciprocable slide 01, which is movable along guides d (1, supported on a bracket d, attached to the frame 0. The upper side of said slide has two inwardly-turned flanges d (1 which loosely inclose the edges of the ribbon and keep said ribbon in place on the slide. Two grippers 01 d are pivoted on the sides of the slide to engage with the ribbon when moved out from the position to feed. The said grippers are pressed up by coil-springs 01 (See Fig. 10.) Holding pawls or grippers d d, located between the slide d and the platen b, hold the ribbon against any back movement. The movement is imparted to the paper-feeding slide d through a depending bar D, which has its upper end pivoted and its lower end forked to engage with a pin (1 projecting from a side of the said slide. This bar D has a cam-slot D, partaking of the angularity shown. Engaging with this slot D is a pin D, projecting from the bar A, and thereby a pendulum movement is imparted to the bar D. I

E is a second depending bar, which is pivoted at its upper end to supports in frame 0 and provided with a cam-slot E, into which a pin E" from bar A projects, and movement is thus imparted to said bar E. This bar E has a staple depositor e on its lower end which moves in to dislodge each staple from the former 6 into the rear passage 6, from whence it is driven by the point of of the plunger a. (See Figs. 15 and 16.)

The parallel rock-shaft B has an arm B projecting therefrom, which passes loosely through a loop B on the bar A, and thereby said shaft B is oscillated according to the movement of bar A. The ink-pads F are supported on angle-arms F, attached to shaft B, and are moved to and from the type-wheels 0 (See Fig. 5.) The wire f is fed and form 0. from a roll across the top of the former e by means of a gripping-pawl f, which is pivoted on upright part of a slide f. The said slide is inclosed in a slotted housing or guidef which joins the plunger-guide g. The said housing or guides f and g are made fast to the frame C and are thus stationary. The wire-feeding slide f has two pinsf projecting out, between which an arm f projects. The said arm f is fixed to the rock-shaft B and is moved thereby. f is a stationary holding pawl mounted on the top of the guide-housingf This pawl holds the wire while feed-pawl f moves to engage with the wire to feed it. The wire passes through the slots f of the pawl-supports and below the edge of the cutting-knife g and thence across the upper side of the staple-former 6 within the plunger-guide 9. (See Figs. 4 and 7.) The knife 9 is attached to an arm g, projecting from and secured to the rock-shaft B. (See Fig. 4.) After the wire is fed across the top of the staple-former e and cut the part a" of the plunger descending on each side of the former bends the ends of the wire, and thus forms a staple. \Vhen the plunger thus descends, the staple previously formed is driven by the driving end a of said plunger. The depositor 6 moves in to dislodge the staple from the former 6 just prior to the descent of the plunger.

Referring, again, to the type-wheels 0, each of these has figures throughout its periphery which are printed upon the tickets to indicate the usual data placed on such tickets. The said wheels are fixed to telescopic tubes h, fitting one within the other and turning freely one upon the other. The said tubular or sleeve portions are graduated in length. The innermost tube is loosely supported on a shaft h, which is mounted in bearings h. From these hearings there extend pins h that pass through cars 72, on the sides of the bar A. Coil-springs 7L surround the pins 72,3, and the type-wheels c and form 0 are enabled to yield when the impact is made with the platen in printing upon the ribbon. Upon the opposite ends of the sleeves h there are placed toothed wheels i, which have upon their rims figures corresponding to the figures on the wheels 0, but occupying different positions. By these means the type -wheels may be turned to change the figures thereon when it is desired to change the printing. The wheels t' afiord an index or guide for turning the wheels h to the proper positions. The wheels tare locked in position after each adjustment, or change by means of the drop-pawls j, which fall by gravity into the notches of said wheels 2'. The pawlsj are pivoted on a common shaft K on the main actuating-bar A.

The printing-form c is permanent and contains the names of the firm or other person or persons selling the goods to which the tickets are attached.

I now call attention to Figs. 9, l1, and 18, in which G designates a yoke attached at its upper end to the bar A. An operating-rod H is screwed or otherwise connected to the said yoke and passes down through a tubular standard I, connecting with a foot-treadle J. The platen is, which cooperates with the stapling devices in uniting the staple and ticket, is moved up to a position to thus cooperate and support the ribbon or ticket and the material or article to which said ticket is to be attached just as the staple-driver a is descending on the staple. The said platen has a stem or extension 70, which projects down through a guide 70 and has attached to its lower end a weight 70 The lower end of said extension 70 is pivotally connected with a forked lever M, which is fulcrumed on a bearing N, attached to the bottom of the frame. (See Figs. 9 and 11.) The other end of the lever M is similarly connected to the sides of an angular connection 0, through which the operating-rod H passes. Surrounding said rod II and resting on the cross-piece of said connecting-piece O is a coil-spring 0'. When the rod If is pressed down by the foottreadle, the bar A is immediately aifectcd; but the lever M is not affected to elevate the platen 70 until the shoulder P of the yoke G engages with the top of the spring 0. This occurs just prior to the completion of the de scent of the staple-plunger a. In the initial movement of the platen 70 the knife-edges m and m cut the ticket. The continued up movement of said platen holds the ticket against the plunger-guide g in a position to receive the staple and become united to the goods. The ink-pads normally rest against the type-wheels and form.

The mechanisms are timed to operate as follows: Pressure applied to the foot-treadle J will cause an immediate lowering of the bar A, and simultaneously therewith the shaft B is oscillated, the ink-pads begin to move away from their normal positions, the ribbon-feeding slide d and wire-feeding slide f begin to move to positions from which to feed, the staple-depositor e moves away from the former e, and the staple driver or plunger moves down. lVhen the feed-slide d completes its movement to the position to engage the ribbon to feed it and just before the completion of the movement of the wire-feeding slide f to the position to engage with the wire, the platen 7c begins to move up, the ticket is cut by the knife-edges, and the staple-plunger and the platen 70 complete their movements toward each other simultaneously. Upon each down movement of the staple-plunger the ticket is stapled, and a staple is formed for the next operation. The wire is out just prior to each operation of forming a staple. The return or upward movements of the bar A and shaft B feed the ribbon and wire and move the staple-depositor over the former; also, the ink-pads are returned to the type-wheels and form. I provide means for compelling a full downstroke of the rod I-I, so that an imperfect or incomplete feed of the paper and wire is at all times avoided. This means consists IIIO of a ratchet H, attached to the standard, a sliding pawl H" engaging therewith and carried on a slide H guided on a bar H". A connecting-bar H connects this slide with the foot-treadle J When the slide H moves down, the pawl H" passes freely over the ratchet; but when the movement stops the said pawl immediately engages with the ratchet and prevents an upward movement of the rod H until after the down movement is completed.
