BUTTON-ATTACHING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 405,328, dated June 18, 1889.

Application filed August 25, 1886. Serial No. 211,871. (No model.)

v full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form a part of this specilication.

Figure l is a front elevation of my improved button-attaching machine, a section being taken through the anvil to show the two prong-clinching depressions in its surface. Fig. 2 is a side elevation of the righthand side of the machine, the clinching and button-carrying jaws being represented fully raised. Fig. 3 is also a side view. Fig. 4 is a horizontal sectional view taken on line x 0c, Fig. 3. Fig. 5 is a perspective view of the feed tube or spout, and Figs. 6 and 7 are perspective views of the two halves of the removable button-guide detached from one an other.

This invention relates to certain novel im provements on machines for fastening buttons to shoes, clothing, and other articles, which improvements will be fully understood from the following description, when taken in connection with the annexed drawings.

In the annexed drawings, A designates a tubular pedestal or the main frame of my improved machine, which is cast entire with a flanged base A', an anvil-extension A2, having concavities a a in its upper horizontal surface, and guide-extensions A3 A3, which are vertically slotted to receive the shanks B B' of two gripping-jaws C C. j

Inside of the pedestal A is a vertically-movable plunger-rod D, the upper end of which is curved forward and has suitably pivoted to it the upper end of the shank B of one of the gripping-jaws C. This upper portion of the plunger-rod D is provided with. a stopshoulder b, which contacts with the upper end of the pedestal A when the plunger-rod with its jaws is at the terminus of its downstroke.

Surrounding the lower part of the plungerrod is a coiled spring E, which bears down upon a collar c, that rests upon the upper end of a tubular (gaspipe) standard F, screwed into the lower end of the pedestal A, (shown in Fig. 2,) through which standard a rod is designed to pass that connects the lower end of the plungerr0d to a treadle. By depress* ing this treadle the plunger-rod with its jaws will be forced down for clinching the buttonfasteners on the anvil A2, and by releasing the treadle the spring E will throw up the plunger-rod and its jaws. The shanks of the jaws C C are vertically movable in the slots of the guide-extensions A3 A3, in which slots the said shanks are held by caps d d, confined by screws e e.

The jaw-shank B is pivoted to the curved overhanging end of the plunger-rod D, as above stated, but the shank B is loosely attached by a lug and slot at f to the jaw-shank B, and the upper end of this shank affords an abutment f' for the upper end of the shank B', as clearly shown in Figs. 2 and 3 of the annexed drawings.

The two jaws C C are caused to spring apart during their ascending strokes by means of a spring g, arranged between the shanks B B', and during the descending strokes the said jaws are caused to approach each other by means of the inclined bearing on the edge of one of said shanks acting against the end of the lower guide slot, thereby lirmly gripping and holding the buttons and their fasteners during the clinching of the latter upon the anvil A2.

The gripping ends of the jaws C C (shown in Fig. 3) are rabbeted and especially adapted to receive the eye of a button and the arched attaching portion of afastener. On the righthand side of each jaw C is an odset h, for a purpose which I will presently explain.

G designates a curved rigid arm, which is free to slide up and down by means of guides To the lower part of this curved arm I rigidly secure removable button-guides I-I, which are curved, as shown in Figs. l, 6, and 7, and preferably made of two longitudinal parts IOO ' raised position shown in Fig. 1.

with a narrow space between them for receiving the eyes of the buttons and properly guiding the buttons, with their fasteners attached, from the feed-tube or magazine J, and delivering them one at a time between the gripping-jaws C C, when these jaws are in the The curved guides H are inclined at such an angle that the buttons with their fasteners will slide down and be delivered to the jaws C C by their own gravity. The lower ends of these guides H are constructed with lipped extensions c, which lie in the path of the offsets 7L, so that the guides H with their arm are lifted a short distance by their offsets during the ascending strokes of the jaws C. The arm G, with its curved guides H and magazine J, is caused to rise by the offsets h striking the lipped extensions it' during the upper part of the ascending stroke of the jaws C C, and the said arm is allowed to descend byits own gravity during the descent of these jaws. Bythese meansA the guides and magazine are jarred and the buttons caused to descend to the Vspring-stop fy. (Shownin Fig. '7.) During the descent of the jaws C C the upper curved end of the dog K `is struck by contact with the upper end of the slot 7cX through the shanks B B 0f said jaws and moved tothe position indicated on Fig. l by dotted lines, in which position the pusher p on the lower arm of the do'g K is adj usted behind a button temporarily held back by the curved end of the spring y. During the ascent of the jaws C C land arm G the pusher of dog K is caused to release a button from the said. spring y and leave it in a proper position between the jaws LC C to be gripped thereby. It will be observed that the free end of the spring y passes freely through a hole made through one of the guides H, and is curved downward, so as to yield and allow the pusher p to take the buttons one at a time.

The upper ends of the guides H are provided with extensions adapted to receive the sheathed end l of the feed-tube or magazine J and to hold the same in an inclined position, which tube is rectangular in cross-section and constructed with a longitudinal channel through its upper wall adapted to receive the necks of the but-tons with fastenings attached and to guide the same properly to the slot or channel of the curved guides H. The tube J is removable from the curved guides, and, like these guides, it receives the buttons on top of it. Consequently I am able to use large or small buttons and feed various sizes with equal facility to the gripping-jaws' C C.

In combination with the above mechanism I employ a pivoted feeding-dog for positively delivering the buttons with their fasteners attached, one at a time, to the gripping-jaws C C.

K designates my improved feeding-dog, which is pivoted at 1t to the right-hand side of the vlower guide extension A? and constructed with a curved extension j) on its upper end, which passes through a slot in the jaw-shanks. On the lower curved portion of this dog K is a broad. tapered button-pusher p', which is designed to separate the last button from the row between the guides H and move it between the jaws C C in proper position.

The operation of themachine is as follows: The tube J is charged with buttons having fasteners attached to them and secured to the curved guides H. The buttons will by their own gravity iill these guides and be arrested by the springg/on the guides H. Vhen the treadle is released, the spring E will throw up the jaws C C to the position shown in Fig. l, carrying with them the guides H H, their tube J, and curved arm G. As this movement takes place, the slot in the shanks operates upon the upper end of the 'dog K and causes its lower end to separate one button from the row and properly deliver it to the jaws C C. is to be attached is adjusted upon the anvil beneath the said jaws and the latter forcibly brought down, carrying with them the button and its fastener and firmly clinching the spurs of the latter in the said material. The saine operation is repeated.
