Aug. 15, 195o INVENTOR. JOHN n4 SEM/EL 1.,

Patented Aug. 15,` 1950 U'Nrrnn STATES PATENT A 2,518,643 rWoTr'IEoE BUfr'roN "John `W. Seweli, St. Louis, Mo. appneaimncniy 1941,'seria1iyo. #16a-rizzo` I 1 claim.' (C1. 24J- 90) This invention relates metal buttons, and contemplates, a construction inwhh the button is formed in two pieces, one providing av body providing a rolled rim anda central cupped portion. and the other providing a cap adapted to t snugly in the clipper' portion ofr thebody.

It is among the objects of the invention to provide a buttonl of the type described which is simple in construction and which may be manu-` factured at a relatively lowcost. Y

Further objects of the invention `reside in the provision da' button or the type described which is of rugged, durable construction, which neat in appearance, and which presents only smooth surfaces at the thread openings, to the end that the thread securing the same to the garment will not be frayed or cut. l

The invention, as will hereinafter fully appear, is applicable to two-hole and four-hole types, in which the holesextend transversely through the button, as well as to fshaxik type buttons in .which one. or more passagesextend through the.. rearface of. the button, the trontiace being free from openings.

The foregoing and other objects and features of the invention will be made fully apparent to those skilled in the art from a consideration of the following detailed description taken in conjunction With the accompanying drawings, in which:

Figure 1 is an elevational view showing the front face of a four-hole button constructed in accordance with the invention.

Figure 2 shows a section taken on of Figure 1.

Figure 3 is a fragmentary section showing the application of the invention to the body of a button of the typehaving a thread passage through the rear face only of the button.

Figure 4 is an elevational view showing the rear face of the fragment shown in Figure 3.

Figure 5 is a view similar to Figure 3, but with the closing cap for the central pocket of the body portion in position.

In the drawings, reference numeral I0 indicates generally the body portion of the button, which body is formed of a single disc of sheet metal, the periphery of which has been rolled into an oval rim II. The rolled rim II is completely closed, being formed with a slight overlap, as will be seen in Figure 2, and from the rim I I a web portion I2 formed of a single thickness of the sheet metal tapers slightly in the direction of the rear face of the button. to the the line 2-2 to improvements in central Ypocket I3. The pocket I 3r .is formed by extrud'ing the metal of the disc rearwardly and has a smooth cylindrical interior wall and .a flat internally-projecting.annular flange I4, from the inner edge of which the metal is further extruded rearwardly, as indicated vat I5, so that the bottom of the. pocket ,lies rearwardly of the flange IL 'From the rear side of the button the bottom of the packet. is pierced inwardly to form a nurnber of thread holes I6. In this instance, four holes ,Iii are shown. However, it willrbe understood that a. two-hole button may be formed in the same manner.. The metal around the thread holes ISB is extruded inwardly toward the front ofthe button, the interior wall of this extruded portion. being .smooth and rcund and extending to the. Vplane of the front surface of the annular flange I4.

f The. centralv cupped portion of the body I!) of the button is closed by `a capindicated generally at I'I.. The cap is formed of a metal disc having its central ,portion pressed outwardly, as indicat'edat I8, leaving a fiat peripheral flange I 9.. The .diametery of the cap so formed isvsuch as tov providea press t between the cap and the cylindrical wall portion of the pocket I3 of the body I0. The outwardly-pressed portion i8 of the cap is pierced inwardly from the front side thereof to form a number of thread holes Zil. The number and spacing of the holes 2G correspond to the number and spacing of the thread holes I6 formed in the central pocket of the body member I0. The metal around the thread holes 20 is extruded inwardly toward the rear of the button, the interior wall of this extruded portion being smooth and round, corresponding to the thread holes I6, and these extruded portions extend to the plane of the rear face of the annular flange I9.

The two pieces comprising the body I and cap I1, formed in the manner described, may be easily assembled by pressing the cap into the cylindrical portion I3 of the central pocket of the body I0 with the thread holes I6 and 2d in alignment. When the two pieces are so pressed together with the rear face of the flange I9 on the front face of the ilange I4, the extruded Walls of the thread holes I6 and 20 are in con- I tact at the interior ends thereof forming smooth,

continuous passages through the button. The press fit may be relied upon to hold the two pieces together, or the parts may be swaged and corrugated, the corrugations extending radially of the button in the flange portions I4 and I9.

The Construction described in the foregoing may be slightly modied, as illustrated in Figures 3, 4, and 5, to provide a button of the type having a thread hole or passage extending through the rear face of the button, and having no openings through the front face. Such buttons are sometimes called shank buttons, and will be so referred to herein.

In these figures, a portion of the web of the button is indicated at 22, and it `will be understood that this portion corresponds to the yweb I2 of the form previously described. In the modified form,

the button is `also provided with a central pocket having a smooth, cylindrical, interior wall portion holes being rearwardly displaced with respect to terminating in a flat, internally-projecting an;

'nular flange 24. From the inner edge of the flange 24 the metal is further extruded rearwardly, as indicated at 25. The extruded portion 25 extends substantially further than the extrudedl portion l5 of the form previously described.

The rounded sides of the extruded or Aoutwardly-pressed portion 25 are pierced von diametrically opposite sides thereof with punches designed to split the metal at the central point of the punch, forcing the metal inwardly, as indicated at 26. Preferably, the punches will be of a generally rectangular cross-section, and the two openings so formed jointly provide a thread passage extending through the button in a direction substantially parallel with the central plane thereof.

The central pocket of the button is closed with a cap indicated generally at 27. VThis cap corresponds to the cap I7 of the form previously described, having a portion 28 pressed outwardly from a peripheral flange 29. However, this portion 28 has no perforations correspondingv to the perforations of Figures land 2, leaving the front face of the button imperiorate.` In this form also the cap 21 makes a press fit with the cylindrical wall portion of the pocket 23.

While there have been herein described certain preferred embodiments of the invention, other embodiments thereof, within the scope'v of the appended claim, will be obvious to those skilled in the plane of said bottom plate and curved forwardly so as to provide rounded margins around thethread holes, a plane circular front plate secured in said cup and engaging the forward side of said bottom plate, said front plate being formed withl thread holes registering with the thread holes of the cup bottom plate, the material of said front plate between and surrounding its thread holes being curved forwardly with respect to the plane of said front plate to provide rounded margins around the thread holes, the rounded margins ofthe cup bottom plate and of the front plate conjoining to provide continuous convexly rounded surfaces.
