MACHINE FOR ATTACHING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 274,407, dated March 20, 1883.

Application tiled September 4, 188'2. (No model.)

To all whom it may concern Be it known that l, PARKER H. SWEET, Jr., acitizen of theUnited States, residingat Nashington, in the District of Columbia, have in- 'vented certain new and useful Improvements panying drawings, and to the letters and iig-- nres of reference marked thereon, which form a part of this speciiication.

ldy invention has for its object to provide a machine of novel construction for automatically attaching buttons, by means of metallic fastening-prongs, to shoes, gloves, or other art cles of wearing-apparel and it consists, essentially, of a stand or frame of peculiar construction, which is provided with a vertically-arranged plunger-rodhaving a recess or holding-jaw at its lower end, which is adapted to receive and hold the button and its connectingpron gs un til they are set or attached to the desired article. v

lt also consists of asupply hopper or-chute and feed mechanism for automatically adjusting a button and its connecting-prongs into the holding-jaw of the plunger as soon as the preceding button has been attached or set; and it further consists of other details of construction and general arrangement of parts, all as will be hereinafter more fully described, and Vspecifically pointed out in the claim.

1n the accompanying drawings, Figure 1 represents a side elevation of my inventionv in partial section; Fig. 2, afront elevation of the same; Fig. 3, a vertical section of the base and die-block, taken on the line .r a: of Fig. l; Fig.

ger, and Fig. 5 a top plan view of the die-block. Similarietters of referenceindicatelike parts in the several figures.

Referringto the drawings, the stand or frame of my machine is preferably composed of a base or table, A, an enlarged and curved arm, v

A', and a cylindrical arm, A2, all formed of a single casting, the cylindrical arm A2 of which is bored out to receive a vertically-arranged.k and sliding plunger, B, as shown in the drawings. This plunger B, which may be operated by hand, treadle, or other power, is provided at its base with a suitable recess or holding-jaw, c, to receive and hold the button and its.fasteningprongs, while its upper part is hollow and adapted to receive a coiled spring in a lmanner well known.

The holding-jaw a of the plunger B consists ot' a suitable recess orcavity provided with an inclined or wedge-shaped bottom,havinga slot extending nearly through the same to receive the shank of the button, and said slot being concaved or grooved upon its lower surface to hold the setting-prongs in place, in a manner well-known to the trade. A

IThrough the central portion of thecurved and enlarged arm A is provided an inclined chute, b, having a central rib, c, through and upon which the buttons and their fasteningprongs are fed down to the holding-jaw of the plunger B, as fully shown in Fig. l.

C represents a dovetailed dieblock, ,arranged to slide in grooves of a corresponding shape in the base A, said block being provided with a suitable die, d, to curve and deiiect the prongs of the fastening device back into the material to which the button is to be secured.

In the operation of my invention the vertical plunger B, carrying a button and its setting-prongs, is brought vertically down upon the material to which the button is to be attached, causing the prongs of the setting device to pass through the material and to enter the die, to he clinched or turned back into the material, which may then be pushed to one side to release the attached button from the recess in the holding-jaw. As the plunger re turns to its former position, through the me-4 dium of the coiled spring in its upper part, it pulls up the small rod e, which, acting upon one end ot' the pivoted crank f, causes the linger g to push another button and its fasteningprongs into the holding-jaw of the plunger B, and this operation of supplying the said holding-jaw is repeated as each button is set or attached to the desired article.` The die-block G may be slipped out and placed in the lower groove, h,in the base A when it is desirable not to have the prongs clinched' into the material,

ICO

the prongs in that case passing through the hole i in the base A.

I do not confine myself tothe means for setting any particular fastening-prongs, as the shape of the holding-jaw and feeding-hopper may be modified to conform to the various styles of setting-prongs now in use.

Having thus described my invention, what l claim as new and useful is- The herein-described machine for attaching buttons to Wearing-apparel, consisting of the Witnesses:

R. PERRY SWEET, BENJAMIN C. POLE.
