from both sides. To buttons of this type the drawback is inherent that in course of time the fabric is torn by the connection between the two parts of the button getting loose,
whereby the clamping efi'ect of the button on the fabric is eliminated and the screw shank of the button alone is left in engagement with the fabric which, particularly for buttons for transmitting lateral tension, such as trowser buttons for fastening the suspenders is disadvantageous.
This disadvantage is overcome in the button according to the invention by providing the side facing the fabric of the one part of the button with at least one circular projec tion and the other part with an adequate number of corresponding recesses, suchwise, that the corresponding elements interengage, thereby unmovably clamping the fabric around the screw shank.
This arrangement enables to provide the button, when serving as a trowser button for the purpose hereinbefore described with a removable hook for attaching the connecting bands on the underwear thereto.
In the drawings several embodiments of 80 the invention are illustrated by way of example, in which Figs. 1 and 2 each show a perspective viewof a first constructional form of the button; Figs. 3 and 4 are sections corresponding 85 to the Figs. 1 and 2;
Fig. 5 is a cross section of this form of the button;
Fig. 6 shows a modified constructional form of the button, partly in a vertical section and in side elevation respectively, and
Fig.7 is a front elevation to Fig. 6.
The button shown in the Figs. 1 to 5 is made I in two parts, a front part 1 and a rear part 2 which by means of the screw shank 3 passing through the cloth S is screwed to the part 1. For facilitating the parts being screwed together the edge 1a of the front part isserrated and the rear part is provided with a transverse slot 2a for engagement with a screw driver or the like. The inner side of the front'part is formed with a circular pro- .jection lb and the rear part is provided on its inner side with a corresponding recess 26 between which two gripping elements the cloth S is pressed, thus relieving the screw 6 3 from fastening the button on the cloth i alone. n
The periphery of the rear part is formed with a groove 20 enabling a springy wire hook 4 to be pressed in engagement therewith. to This wire hook serves for attaching the connecting bands on the underwear thereto, whilst the suspenders, in known manner, are secured to the button. 7 j
In the constructional form shownin the Figs. 6 and 7 the front part 10 is fastened to the cloth by means of a head screw 11 constituting the rear part and a sheet metal hook 12 is connected to the screw behind the head of the same. The back side of the hook 12 has an annular groove 12a into which extends a circular projection 10a on the inner side of the front part which is concentric to the screw and of triangular cross section, thus holding the cloth S which is pressed between these 7.5 two interengaging elements, so as to firmly secure the button on the cloth. The edge of the front part is serrated also and the head of the screw provided with a transverse slot.
I claim: 7 $30 1. A button for attachment to cloth in two separable parts, in combination, a front part to present the aspect of a garment button, a head provided on said front part, a base formed on said front part in close proximity no to said head, a rounded-01f peripheral taper provided on said base at an obtuse angle, a rear part connected to said front part by screw engagement and a rim complementary to said taper formed on said rear part, and 31) adapted to. push the gripped cloth portion past the outer edge of said taper for locking said screw connection without damaging the cloth.
2. A button for attachment to cloth in two separable parts in combination, a front part to present the aspect of a garment button, a head provided on said front part, a base formed on said front part in close proximity to said head, a circumferential abutment for .9
the cloth provided on said base, a rear part connected to said front part by screw engagement, and a gripping face complementary to said abutment arranged on said rear part and adapted to push the gripped cloth portion past the outer edge of said base for locking said screw connection Without damaging the cloth. a
In testimony whereof I have signed my name to this specification.
