SEW- ON BUTTON Filed Jan 29, 1954 Iw/vefiioz': iusifav J0 7122/6 on dizzy Patented Oct. 20, 1936 UNITED STATES PATENT OFFICE SEW-N BUTTON Gustav Johnson, West Roxbury, Mass, assignor Application January 29, 1934, Serial No. 708,788
1 Claim.
My invention aims to provide improvements in buttons particularly of the sew-on type.
In the drawing which illustrates a preferred embodiment of my invention:-
Figure 1 is a bottom view of a button provided with my improved sew-on back;
Fig. 2 is a side elevation of the button shown in Fig. l;
Fig. 3 is an enlarged section taken on the line 10 3-3 of Fig. 1;
Fig. 4 is a plan view of the inner face of the blank from which the sew-on back is formed and shows the first step in forming the apertures and reinforced edges;
Fig. 5 is an edge view of the blank shown in Fig. 4;
Fig. 6 is an edge view of the blank showing the rounded edges adjacent the apertures; and
Fig. 7 is a plan view of the blank shown in 20 Fig. 6.
Referring to the particular button selected for illustration of my invention, I have shown a twopiece metal button including a top plate I and a back plate 2 secured together by rolling the 25 edge 3 over the peripheral portion 4 (Fig. 3).
The back plate 2 is provided with a relatively short boss 5 of substantial diameter and extending away from the button portion, as shown in Figs. 1 and 2. This boss portion 5 is provided with a pair of thread-receiving apertures 66 located at opposite sides of the boss and surrounded by rounded walls 1---'! of double thickness. These walls are particularly desirable because they present smooth surfaces 35 against which the thread may bear when the buttons are sewed in position.
The thread-receiving apertures are preferably formed in the blank from which the back plate 2 is formed while the blank is fiat, as shown in Figs. 4 through '7 inclusive. Also the inwardly turned portions to provide the smoothly rounded walls 1-1 surrounding the apertures 66 are formed while the blank is fiat. As illustrated in Figs. 4 and 5, tubular portions are pressed from the blank providing the back 2 thereby forming the thread-receiving apertures 66. Thereafter the tubular portions are turned outwardly and downwardly against the back plate blank, as shown in Figs. 6 and '7. After the final operation of forming the smoothly rounded walls the back plate 2 may be formed into any desirable shape and the boss portion 5 may be pressed from the center thereof.
My improved button is particularly desirable as one to be attached by sewing threads, because the thread-receiving apertures 6-45 are surrounded by smoothly rounded inwardly folded walls '|-'l to prevent cutting of the threads as is the case when button backs are provided merely with apertures surrounded only by a wall of single thickness. In that type of structure the wall presents relatively sharp edges which cut the threads thereby loosening the buttons.
While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claim.
I claim:
A sew-on button having a projecting hollow boss portion at the back formed from sheet metal and having a convex bottom at its outer surface, said boss having a pair of thread-receiving apertures located at opposite sides thereof and spaced above the bottom of said boss and a doubled-over wall inside said boss and surrounding each of said thread-receiving apertures.
GUSTAV JOHNSON.
