MACHINE FOR ATTACHING BUTTONS.

SPECIFIQATION forming part of Letters Patent No. 282,821, dated August 7, 1883.

Application filed April 28, 1883. meander To all whmn it may concern:

Be it known that I, ALEXANDER G. WIL- KINS, of Meadville, county of Crawford, and State of Pennsylvania, have invented certain Improvements in Machines for Fastening Buttons to Shoes and other Articles; andI hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation. Fig. 2 is an elevation taken on the side opposite Fig. 1. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is a vertical section on the line :10 00 of Fig. 3, showing the front of the machine. Figs. 5 and 6 are details to be referred to.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A is the frame of the machine, having a slotted standard, B, through which projects an inclined feedway, O, for the pin fasteners and washers, and an operatinglever, D,' pivoted at a. Projecting from the front of the bed is a slotted vertical tube or barrel, E, in which works a plunger, F, the head of which is of a conformation like the upper or outer face of the washer and the 11 ead of the pin. The plunger is operated by a bar, I), one end of which is pivoted to the plunger at b, and the other end reciprocates in a socket, b, in the end of the lever D, to compensate for the tangential movement of the pivot b. On the rear side of the barrel E, near its upper. end, is an opening, (Z, against which abuts the lower end of the pin feedway G, and through which-the pins and washers are deliv ered to the interior of the barrel E, where they fall, head downward, upon the upper end of the plunger, to be carried up to the fastening point. The opening d is alternately opened and closed by a sliding door, at, set into ways in the barrel, and operated by a rod, (1", loosely connected with it at 2, and having its lower end passing through an eye, 3, on the lever,

This rod is of such a length that as the lever approaches its lowest depression the head 4 brings up against the eye 3 and pulls the door down by overcoming a coiled spring, 5, which normally holds the sliding door closed, and afastener falls into the barrel. ing door is an upwardly-projecting inverted hook, 6, the end of which, when the door is closed, lies immediately over the slot in the feedw'ay C, so that when the door is brought down the end of the hook enters the slot immediately behind the escaping fastener and prevents more than one fastener entering the barrel. As the pins and washers are fed into the barrel or tube E through opening cl, the feedway is so located in reference to the sliding door that the points of the pins are arrested against its edge, while the washers and heads, being comparatively heavy, pitch forward and downward and fall, point upward, on'the anvil. or head of the plunger while the plunger is depressed, and are ready to be forced up by the plunger. The top of the pipe or tube is provided with arms or bearings e e, projecting forwardly and rearwardly, which support a centrally-divided centering-cap, G G, having a conical interior, f, terminating in a central opening, g, through which the fastening-pin passes as it approaches the leather. As the plunger rises the point of the pin enters the leather, which steadies it, and a yielding-spring device sustains the leather until the head of the plunger strikes into theinterior, f, of the divided cap G G, and, passing upward, forces the sides G G apart, and moves upward until the pin strikes the upsetting-tool, and the fastening is complete.

The spring-bolt H, which forms the yielding resistance while the leather is being punctmy invention, are substantially the same shown and described in the application of Mahlon M. Zellers, filed April 17, 1883, and hence I make no claim thereto.

Attached directly to the lower end of the yielding bolt H, and moving with it, is a plate bearing the button-die and the mandrel around which the pin is bent. This plate is divided and the portion h is hinged to the mandrelcarrying portions h at 1;, the division being At one side of the slidured, and the fixed upsetting-tool H shown in just within the right-hand lower edge of the spring bolt H. In the upper face of the hinged piece h is a socket, in which rests the body of ion the button, and in the edge of this socket is cut a recess, Z, in which rests the shank of the button-eye, so that the eye may project within a recess, a, cut in the edge of the plate h, and be held securely beneath the edge of bolt H over central opening, 9, through which the pin approaches the eye. A slot, m, in the eye of plate h allows the pin to pass upward, be clinched downward, and withdrawn. Across the end of the slot in the bolt H, in which is located the end of the upsetting-tool, is the recess 0, into which projects the forming-mandrel I. This forming-mandrel has a finger, p, on its front end, a squared portion, g, which slides into the square box a", rigidly secured to plate h, and a rearwardly-projecting shank, 8, around which is a coiled spring, 7, having its end secured to a stud, 8, on the plate, and which serves to keep the mandrel normally pressed forward. On the upper side and front end of the squared portion q of the mandrel is an upwardly-proj ecting lug, t, provided with a beveled faceadapted to come in contact with the beveled face of an adjustable projection, t, secured to the head of the machine, and the lug t, coming in contact with the projection t, retracts the mandrel and withdraws it from the loop of the pin as it is finished.

The buttonfeed tube K is held by a bracket, L, secured to the head 30 of the machine, and provided with a set-screw, M, whereby varying sizes of tubes can be used with facility. At the lower end of the tube the buttons are checked by a stop, 10, on the lower end of a flat spring, 13. This flat spring also carries a projection, 11, which enters a slot, 12, in the button-tube behind the lowermost button, at the instant the stop 10 is forced from over the lower end of the button-tube by means of the hingedpiece or plate it being thrown around until it strikes a projection, 25, on the lower end of spring 13 and forces back the stop 10. This movement of plate h brings the button socket or recess 15 under the tube, a button drops into the socket, and the plate h is swung around to the fastening-point, where the button is secured.

When fasteners of this description are. clinched very closely, if the body of the button is held rigidly in a socket, there is danger of bending the shank of the button-eye. This I am able to avoid by cutting away or hollowing out the side of the yielding springbolt H at 26, near the button, so that if too great a strain is put upon the button-shank the upper part of the body of the button can tip over toward the bolt H and relieve the strain.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a button-fastening machine, the barrel E, provided with the interior plunger, J3, and an opening for the entrance of the fast 'eners, in combination with a feeding device,

0, which feeds the pin point downward, anda tripping device, substantially as described,

for turning the fasteners as they fall, whereby they are thrown head downward onto the end of the plunger.

2. In a button-fastening machine, the barrel E, provided with plunger F, in combination with lever D, having the hollow end, and the reciprocating bar b, substantially as and for the purpose set forth.

3. In a button-fastening machine, the barrel E, provided with an opening to receive the fasteners, and lever D, in combination with the sliding door (1, spring 5, pivoted headed rod 611, and eye 3, all constructed, ar ranged, and operated as set forth.
