IVALLAOE E. JACKSON, OF VVATERBURY, CONNECTICUT.
SPECIFICATION forming part of Letters Patent No. 465,061, dated December 15, 1891.
Application led NovemberlS, 1890. Serial No. 371,842. (No model.)
To @ZZ whom t may concern;
Be it known that I, WALLACE E. JACKSON, a citizen ot' the United States, residing at Vaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Button, of which the following is a specification.
'lhis invention relates to improvements in buttons of that class employing inits construction a tubular hub and a countersunk turner-plate, and the objects in view are to provide a button embodying these features and to improve the general appearance of the button by avoiding the unsightly eountersink appearing ou the face of the turner-plate.
With these objects in view the invention consists in certain features of construction hereinafterspeciiied, and particularly pointed out in the claim.
Referring to the drawings, Figure lis aradial section of a button provided with my iinproveniente, the same being applied. Fig. 2 is a similar view previous to its application. Fig. 3 is a detail in section of the hub before the assemblage ofthe button. Fig. t is a similar view as it appears after assemblage. Fig. 5 is a detail in section of the tubular shank, the same being shown in full lines as it is before upsetting and by dotted lines as it appears after upsetting. Fig. 6 is a detail in section of the turner-plate.
Like letters of reference indicate like parts in all the figures of the drawings.
In the drawings, the letter O designates the tubular fastener'1 which has a tiange .I surrounding its lower end, whose body tapers slightly toward its upper end and is closed and depressed at its `center, as at c.
The letter E designates the4 turnerplate, having a downwardly-extending tip or countersin k at its center, as shown in Fig. G. \Vhen these two parts ofthe button arebrought forcibly together, the tip of the turner engages the depressed center of the fastener and the beveled sides of said clip cause the upper rolled end of the tubular body of the fastener to spread, as shown in dotted lines in Fig. 5. By this motion the depressed center c is brought upwardly nearly into a plane at right angles with the axis of the button, and the diener and is passed through the opening in the back-plate, with the edge of which the upper end of the hub interlocks or engages, the body of the hub forming the shank of the button. This hub, Figs. 3 and a, is a tapering tube with a flaring flange J around its lower end. Near its upper end it has a shoulder 7L, as shown, and when it is pressed into place the part above the shoulder curls over and clam ps the neck of the button.
.As thus far described the button is of the ordinary construction, and it will be noted that the face of the same is somewhat marred by the presence of the countersink of the turner plate. My improvement therefore consists in the outer covering or face-plate F. This plate is slightly larger than the backplate and turner-plate, and its periphery or edge is turned and crimped under the back I, as at f, thus clamping those parts together. The face-plate F may be left perfectly plain or ornamented in any suitable and well-known manner.
Having described my invention, what I claim is The herein-described improved button of the class specitied, the same consisting of a tubular flared shank the upper end of which is closed, the hub ll, encircling the shank,the back-plate I, encircling the hub, the turnerplate F., having a central conical depression mounted upon the back-plate, which depres-
