3 Claims. (CI. 24-105) This invention relates to a separable button, more particularly of the type use for a lapel emblem; and has for one of its objects to provide for the securing of a button in place to prevent accidental unscrewing of the separable parts thereof.

Another object of the invention is to utilize the resiliency of the fabric to which the button is attached to apply tension to increase the friction and prevent accidental unscrewing of the parts.

Another object of the invention is to locate the frictional pressure where it will be most effective in its operation.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a perspective view illustrating the button as applied to the lapel of the coat;

Fig. 2 is a sectional view through the button and the fabric to which it is attached;

Fig. 3 is a perspective view of one of the members of the back unit of the button;

Fig. 4 is a View on substantially line 44 of Fig. 3;

Fig. 5 is a sectional view of the other member of the back member of the button;

Fig. 6 is a perspective view of the back unit assembled;

Fig. 7 is a top plan view of a modified form of unit such as shown in Fig. 5;

Fig. 8 is a bottom plan view of a modified form of unit such as shown in Fig. 3; and

Fig. 9 is a section on line 9-9 of Fig. 8.

In the use of separable buttons such as are used for emblems on the lapel of a coat, two separable units are provided to engage opposite surfaces of the fabric and it is desirable to have some part of the back unit grip the back of the fabric when moved into engagement therewith and be nonrotatable, and another rotatable part urging the fabric-engaging part toward the fabric. In such an arrangement the provision of friction to prevent relative rotation of the members of the back unit is desirable, and it is provided in the present case at a location spaced 2. maximum distance from the center of rotation which will be most efiective; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accom-v plished:

With reference to the drawing, one unit of the button comprises the face plate III which will be provided with some emblem or other which is to be displayed. This face plate may be separate from and secured to a flange which is integral with the threaded post I2 extending rearwardly therefrom. This post I2 will extend through an opening I3 in the fabric I4 of the lapel I5 of the coat, as shown in Fig. l, in which position it is desired that the button be secured. Securing of the face unit is accomplished by a back unit designated generally I6 and shown complete in Fig. 6. The back unit consists of two members, one illustrated in Fig. 3 designated generally I1,- and the other illustrated. in Fig. 5 and designated generally I8.

The member shownin Fig. 3 consists of a cylindrical collar portion I9 :having a series of teeth 20 about its edge, these teeth being directed toward the face plate I0 and the collar being concentric with the post I2. A flange 2| extends outwardly at right angles to the central axis of the collar I9 and at its periphery is provided with a plurality of wavy-like portions 22 which provide projections 23 on its undersurface with recesses 24 between these projections 23.

The other member of the back unit consists of a sleeve 25 threaded as at 26 internally to threadingly engage the post I2. Extending outwardly from this sleeve there is a disc-like portion or plate 21 which is of a size slightly larger in diameter than the flange 2I of the member I'I, while upwardly extending from the outer edge of this plate there is a portion 28 which receives within it the member I I. This portion 28 is rolled over the flange 2| of the member H as at 29 (see Fig. 6) so as to loosely assemble the two members together as shown in Fig. 2. Adjacent the rolled-over edge and at the outer periphery of the plate of the disc-like portion 21, I have also provided a series of projections designated 38 upstanding from the surface thereof and which will engage the projections 23 of the member I'I as'relative rotation of the members I 1 and I8 occurs.

As the back unit is assembled on the post I2, the teeth 20 of collar I9 will engage the fabric I4 and this member I1 will then stop turning; while rotation of'the member I8 will feed the back unit onto the post I2 and pressure will occur in the face-to-face engagement of the flanges 2| and the plate 21. The relative rotation, however, will be retarded because of the interrupted flat surfaces formed by knobs 23 on the edge of the member I! and the projections 30 of the member I8. Thus, as turning occurs, it will be necessary to force the projecprojections any loosening engagementwill be retarded because it will be necessary for the pro jections of one member to be forced one over the projections of the other member in any release movement which will not'accidentally occur without manual manipulation.

In Figs. 7 and 8 I have shown a modified form in which relative interrupted surfaces engage the projections 3| closer together and instead of providing a wavy edge at 22, I have here provided an interrupted surface by depressed portions 32 providing ridges 33 between the depressions for engagement with the knobs 3| for retarding .of relative movement of the two members of the back unit.

I claim:

1. In a button, separable units, one unit having a face plate with a threaded'post extending rearwardly therefrom, the other unit comprising a pair of relatively rotatable members, one of said members having a fabric-engaging portion to'which the button is: to be attached, and the other of said members having a threaded socket to. engage said thi'eaded post, said members each having friction means at their peripheral margins with the means on one member extending into the path of travel of the means on the other member and engageable with each other to prevent accidental relative rotation between said members.

2. In a button, separable-units, one unit having a face plate. with athreaded post extending rearwardly therefrom, the other unit comprising arranged somewhat a pair of relatively rotatable members, one of said members having a fabric-engaging portion to which the button is to be attached, and the other of said members having a threaded socket to engage said threaded post, each of said members being generally of disc shape with portions in face-to-face engagement, and each being provided with projections at its peripheral edge, with the projections on each of said members extending towards and in the path of rotation of the projection on the opposite member and engageable with each other as rotation occurs, to prevent accidental relative rotation of said members.

3. In a button, separable units, one unit having a face plate with a threaded post extending rearwardly therefrom, the other unit comprising a pair of relatively rotatable members, one of said members having a fabric-engaging portion to which-thebutton is to be attached, and the other of .said members having a threaded socket to engage said threaded post, each of said members being generally of fiat plate formation and positioned one above the other with the edges of one rolled over the edges of the other, and with the surfaces of each member adjacent to each other provided at the peripheral edge thereof with an interrupted surface portion providing abutments on each member extending towards each. other at a location for the abutments of one member to engage with the abutments of the other member as relative rotation occurs to prevent accidental relative rotation of the said members.
