COLLAR-BUTTON.

SPECIFICATION forming part of Letters Patent No. 653,895, dated July 17, 1900. Application lecl January 29,1900. Serial No. 3,090. (No model.) l

To a/ZZ whom. it may concern:

Beit knownthat I, FREDERICK A. BALLOU, a citizen of the United States, residing at Providence, in the county of Providence and',

State of Rhode Island, have invented certain new and useful Improvements in Collar-Buttons, of which the following is a specification, reference being had therein to the accompanying drawings.

Like letters indicate like parts.

Figure l is a diametrical section of a seamless gold-tilled ball bored and counterbored for use in the manufacture of my improved collar-button. Fig. 2 is a central longitudinal section of the post and shoe of said collarbutton. Fig. 3 shows in central section said post and'shoe in combination with said ball before the ball has been united with the post. Fig. et is a front elevation of the drill for making the bore and counterbore in said ball. Fig. 5 is a side elevation of the same. Fig. 6 is a top plan of the die, in which the ball is united to the post, said die being shown as open. Fig. 7 is a top plan of said die as seen when closed. Fig. 8 is a section of said die on line w o: of Fig. 7. Fig. 9 is the same as Fig. 8, with the post and shank therein in position for the operation. Fig. lO is a view, partly in side elevation and partly in central longitudinal section, of the plunger used in combination, with said die. Fig. ll illustrates the operation of uniting the ball of my improved collar-button with the post and shoe thereof. Fig. 12 shows the parts in position at the close of the operation. Fig. 18 shows in elevation myirn proved collar-button when completed.

My invention relates to collar-buttons made of three pieces and united without the use of solder; and it consists of the novel construction and combination of the several elements hereinafter particularly described and as specifically set forth in the claim.

In the manufacture of my improved button I take a seamless gold-filled ball A, as shown in Fig. l, consisting of a comparatively-thick but hollow body portion o, of base metal, and a gold covering-plate 7J, of usual construction. In this ball I make a radially-directed bore c and counterbore (l, as seen in Fig. 1, using for this purpose the drill B, (shown enlarged in Figs. 4 and 5,) which drill consists of a shank e, flattened broad blade f, (somewhat beveled on two opposite sides, as indicated at 9,) and a flattened narrow cutter h, sharpened t-o a point. Y and the outer end of the bladefis the shoulder 'L' on two opposite sides, as fully illus; trated in Figs. 4 and 5.

In drilling the bore and counterbore c d in the ball A by the use of the tool B said ball is held in any proper vise or support and the drill is rotated under pressure, as usual; but owing to the beveled edges g of said drill the metal is formed into an outwardly-extending ange, barb, or iin (shown in Figs. 1 and 3 at rm) which consists entirely of the gold plate b, brought to asharp edge.

In Fig. 2 are shown in central longitudinal section the post C and the shoe D, united thereto, as usual. The upper end of the post C, as shown at n in Figs. 2 and 5, is formed int-o a Haring or bell shape. The post is made of gold-plated stock, the base metal being indicated as j and the gold covering-plate as k.

In uniting the ball A to the post C of the collar-button I use the die shown in Fig. 6 and the plunger shown in Fig. l0. The die has the body portion E, with a central circular aperture o. A stop-pin p projects from the upper side at the median line. Two dieplates F and G are pivotally mounted on screws q r, which pass through them into the body E of the die, and they are movable on said screws from the position shown in Fig. 6 to the position shown in Fig. 7. The dieplates F and G have the semicircular fiarA ing edges s s', the vertical sides u u', the

Between the inner end of the cutter h.

seinicircular grooves or channels o o', thev semicircular annular lips w w', and the anL nular bottom surface y y. The edge of the die-plate G has a portion thereof beveled, as seen at a. The handle H is pivoted at t to the die-plate F. Said handle has the locking-pin h. The die-plates F and Gr have, respectively, the sockets f and g', which when the said die-plates are closed, as shown in Fig. '7, receive the stop-pin p. The die-plates F and G are locked in place by the friction of the locking-pin h against the beveled edge e of the die-plate G.

In Fig. S I show in cross-section the dies- IOC surface formed by the closure of the die-plates F and G, together with the central Haring aperture fm' between them.

The iiaring bell-shaped end n of the post C is placed in the central semitubular opening of one of the die-plates when the parts are in the open position shown in Fig. 6,' and then the other of the die-plates is swung around into the closed position shown in Fig. 7 and locked in position, whereupon the post C is supported in the closed die in the manner illustrated in Fig. 9. The ball A is then placed on the open iiaring end of the post C, as seen in Fig. ll, the upper end of the post being parallel with, but a short distance below, the annular surface y y of thedies and the annular barb m of said ball entering the annular' groove or channel o Q1 in said closed die and shutting over said end of the post C, as sh'own in Figs. 3 and ll. The plunger I, having in its end a hemispherical socket n', comes down forcibly upon the ball A, whose upper half lits in said socket n', and this downward pressure of the plunger upon the ball seats the end of the post C solidly against the bottom of the counterbore d and also causes the barb m of the ball to bend inwardly and upon the inclined surface of the annular lip w yw of the annular groove or channel u -U of the die to close in upon and come into snug forcible contact with the bell-shaped end of the post C and then to further bind said barb m toward the center of the ball until when the end fn of the post C cornes in forcible contact with the bottom of the counterbore d of the ball A the `Whole of said barb m has been bent up under the iiaring end of the post C with the sharp edge of said barb directed inwardly, thus uniting the ball to the post.A In this manner the ball is firmly secured to the post without the use of solder and the base metal is wholly concealed.

In the manufacture of collar-buttons of solid gold the formation of the barb m may, however, be dispensed with, and the sharp circular edge of the counterbore is closed upon the post by the action of the die, as already described.

In the drawings the figures are all exaggerated in size, (except the dies, Figs. 6 and 7,) so as to more clearly present the novel features of the construction, and the drill and plun gers are shown enlarged for the same purpose, especially the drill B, in order to better exhibit the clearance-bevel g thereon.

Instead of a spherical ball any ornamental .head or knob can be used and connected with the post in like manner.

I claim as a novel and useful invention and desire to secure by Letters Patent- An improved collar-button, consisting of the head or ball A of base metal, having an inclosing gold plate or covering b, and the post C, composed of an inner plate of base metal and an outer gold plate or covering; said head or ball A being provided with the y counterbored for the reception of the flaring end n of the post C which4 is held therein by the overlapping edges m of the covering Z) of the head A, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses. Y
