RIVET-SFETTING MACHINE.

SPECIFICATION forming part of Letters Pgatent No. 416,282, dated December 3, 1889.

' Application filed March 13, 1889. fierial No. 303,170- (No model.)

constructed, arranged, and combined sulostantially as is herein described and claimed.

In the accompanying sheets of drawings, Figure l is a front View, partly in section, of the machine; Fig. 2, a side view, partly in section; Fig. 3, a detail-in part section of the anvil in the planes 9c 00,. Fig. 2; Fig. 4, a

plan view of clamping-plate; Fig. 5, a plan view of receiver arm and plate; Fig. 6, an edge view of same; Fig. 7, aplan or top view of receiver and spring, and Fig. 8 a plan view of gage.

Similar letters of reference indicate like parts in the several views.

This invention relates especially to machines designed to secure buttons to garments with a metal rivet or fastening. Machines for this purpose in a general sense are well known, and it is common to provide such machines with hoppers, chutes, operating-levers, plungers, and receivers forthe rivets and anvils. These several features, combined and constructed in different ways, are common to most machines of this character.

In my improvement on this class of rivet.- setting machines Iconstructthe receiver-arm A with a plate B and pivot to the arm a clamping-plate O. The plate B at its front end is provided with a crotch-opening a and with a stop I). The clamping-plate C has pivoted to its upper surface the lever-bars 'c and d, the front ends of which form the receiver D and the rear ends of which are provided with a spring 8. To the under side of the plate B is adjustably fitted, by means of a set-screw f and the slots 9 and h, a gageplate E, formed with lugs 76. Between the plates B andv C is fitted a spiral spring Z, and between the plate B and the base F of the machine is a spiral spring on. At the forward end of the base F is placed a telescopic anvil G, with a die n centrally located therein. This die is adjustable with the aid of the screw 0. In addition to these described parts, it is to be understood that my machine is provided with the ordinary rotating 110p- ;per, in which the rivets are placed in bulk to find their way thence by the chute H to the I receiver D, and that the machine is also provided with a plunger K and an operatinglever L.

In the operation of my machine, as before stated, the rivets which are pointed and headed find their way from a revolving hopper (not shown in the drawings) to the receiver I) by way of the chute H. A but-ton,

with its hub uppermost, is placed on the anvil G. The garment or fabric for which this button is intended is then placed between the plate B and the clamping-plate C. The pointed rivet, which hasbeen lodged by gravity point downward in the receiver D, is driven through the receiver, the lever-bars c and (l spreading apart for that purpose, and the rivet is also forced through an opening a" in the clamping-plate C. This opening 7' is beveled somewhat, and although the head of a rivet may pass freely through the opening the sides thereof act to some degree as a steadier to keep the rivet in the desired perpendicular position. The rivet being driven by the action of the plunger K through the receiver D and through the opening 1 in the clamping-plate C, its point and shank are thrust through the fabric to which the button is to be attached, the fabric being placed, as stated, between-the plates B and O, the plate 0, as the plunger descends for the purpose of driving the rivet, yielding by reason of its hinged joint t and clamping by this action the fabric between the plates B and C, for an instant holding the fabric tight and smooth, thereby insuring the penetration of the rivet not only truly through the fabric, but in the exact place intended. The rivet, in this way forced through the fabric, is by the continued downward motion of the plunger carried, together with the fabric in which it is inserted, down to the button on the anvil G, when the point of the riveteuters a hole in the hub of the button, the anvil receding and permitting the point of the rivet to enter the die 71 within the anvil, in which die the point is formed into a symmetrical head, and this head on one end of the rivet and the flange or head on the other end of the rivet fasten between them the button to the fabric. The operation above described being finished, the plates B and C, by reason of the pivoted arm A, are restored to their normal positions, ready for the next operation, by the action of, the spiral spring 011., and by reason of the spring Z the plate 0 recovers its former position to admit the fabric between it and the plate B.

To regulate the extent to which the fabric may be inserted between the plates B and C, a gage plate E is, by means of the setscrew f and the slots g and h,adj11sjably fitted to the under side of the plate B, so that the lugs k on the gage-plate may admit the fabric to a greater or less extent between the plates; .and to prevent the accidental thrusting of the fabric beneath the plate B, instead of above it, a stop I) is fixed to the under side of the plate B for that purpose. The notched opening a in the plate B permits the withdrawal of the fabric from between the plates B and C after the rivet and button have been fastened to it, and the front side of the open ing 9' in the plate 0 may, if desired, be cut away, as is shown in Figs. 2 and 4, to enable the operator to observe the position of the rivetwhen using the machine.

Having now described my invent-ion, whatI claim as new, and desire to secure by Letters Patent, is-

1. In combination, in a rivet-setting machine, an arm A, pivoted to the frame of the machine, with aplate B fixed thereto, a clamplug-plate (I, pivoted to said arm, a receiver .1), with its lever-bars c and (I pivoted to the upper surface of said clamping-plate (I, and an anvil G, as and for the purpose described.

2. In combination, in a rivet-setting machine, an operating-lever and plunger, a plate B, fixed to the. pivoted arm A, a clampingplate 0, hinged to said arm, a receiver 1), with pivoted lever-arms c 1?, spring I between the plates B and O, and a spring at between the plate B and the supporting-base of the machine, as and for the purpose described.

3. In a rivet-setting machine, a pla e B, constructed with a notched opening a in its front end and with a stop I), and an adjustable gage E. secured to the said plate, as and for the purpose described.

t. In a rivet-setting machine, the combination of the plate B, connected by a pivot with the frame of the machine, and the plate (3, pivoted to the supporting-arm of the plate B and above the same and provided with a receiver D on its upper surface and with a beveled opening 7', constructed to operate snbstantially as and for the purpose described.

5. In a rivet-setting machine, the combination of the plate B, connected bya pivot with the frame of the machine, an adjustable gage secured to the plate B, and the plate 0, pivoted to the supporting-arm ot' the plate B and above the same and provided with a receiver D on its upper surface and a beveled opening 1', the plate C being constructed to guide the rivet and to be carried down by the action of the plunger and to clamp the fabric through which the rivet is thrust, substantial] y as and for the purpose described.
