My invention relates to separable buttons or emblems of the lapel engaging type.

The essential objects of my invention are the prevention of tearing or braiding the' Y shown 1n F igurc 4, has an annular groove or lapel or other engaged fabric by the teeth in their rotary movement of engagement to simplify the structure and the method of construction of the button, as well as to effect a saving in cost of construction; and to insure an unobstructed swiveling action of the toothed disk.

My invention consists in such parts and combinations of parts, and in such steps and in such successions of steps as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification,

Figure 1 is a side elevation of my button,

Figure 2, a similar elevation partially in central vertical section,

Figure 3, a section on line 3-3 of Figure 2, and

Figure 4, a section of the lower portion of the back member of my button before assembling, and an elevational section of a portion of the crimping tool or die.

Similar reference numerals indicate simil ar parts throughout the views.

A front-.or entrant member 7 includes an ornamental head of any preferred outline fixed to or integral with a shank 8 provided with a thread 9.

The back member or base consists of a circular plate 11 and a central cylindrical elevation 12 provided with an inward bevel in its top as at 13, and with an annular indent 15 at its base; and the plate 11 and the elevation are initially provided with a central bore 16, all as shown in Figure 4.

In this figure is also shown a circular disk 18 provided with a central opening 20 having a beveled face 21 tapering inwardly in a downward direction. Upon the peripheral edge of the upper or front face of the disk 18 is an annular series of relatively broad int-egral teeth 23. The minimum diameter of the opening 20 is slightly lgreater than the maximum diameter of the elevation 15.

In assembling the disk 18 and back member or plate 11, the former is placed upon the latter',l the elevation 12 sliding through the opening 20and projecting above the plane ofthe upper face of the disk18. n

Az'swaging or crimping tool orfdie 25, as

recess 2T in the margin of its operating face Vmerging ina 'centrally located Ydepending conical projection 29,. ATheztool is forced upon and intothe elevation 12,:r'adially expanding and depressing the latter to form an externally conical bearing 31 loosely engaging the beveled disk opening 2O and terminating in an annular rolled over lip or Harige 32 slidably overlapping the disk 13, as shown in Figure 2. member 18 is rotatably engaged with the front or top face of the member 11 and with the bearing 31 and lip portion 32. Subse- Ciucntly the bore 16 ofthe plate is tapped to form an internal thread 33.

The application of this button to a coat lapel is effected by pushingwith one hand the shank 8 of the head 7 through the lapel hole. The back plate 11 is then turnedby the operators other hand which advances 'A the pla-te upon the threaded shank until the teeth 23 contact with the lapel, and sink rectilinearly therein uneffected by the continued .rotary movement of the member 11. Hence the teeth cannot abraid the lapel. Y

I claim f 1. In a. button, ahead, ashank thereon provided with a screw thread, a back plate provided with a threaded hole adapted to receive the thread of the shank, a stationary bearing upon the front of the plate concentric with the h ole, a Adisk rotatably engaging the bearing and the front of the plate, a terminal annular iange upon the bearing overlapping the disk and in slidable contact therewith, and an annular series of forwardly directed teeth upon the margin of the disk. v

2. In a button, a head, a shank upon the head provided with athread, a back plate, a forwardly directed flaring bearing integral with the center ot the plate, said plate and bearing being provided with a central hole,

By the described operation the and said `hole being provided with a thread engageable with the first thread, a rotatable provided with a central opening for the reception oft-lie bearing, said opening being provided with a taper'conforming with the flaring of the bearing, a lateral flange upon the end of the bearing in sliding engagement with theyplate, and forwardly directed teeth upon the margin/of the disk.V

3. The method of constructing the back y members of a separable button consstlngin Vormingf'ap'late andamentwlfcylindriel 'elle' vation with a centralbore mid'lwithnannward bevel upon the free end of the elevation, placing loosely upon the pla-te a dis'kfv with a central opening tapering inwardly in,k

a downward direction, said diskbeing dfless` thickness than the height of the elevation,

thereafter `radially expanding and 'depress- 'ing 'the elevation to externally conform to the 4bevel of the l'isk,a11'd.tooverlapfthe.lat f ter,v and tapping 'the Abore to form lafthread l therein. i

K In ytestimony whereof I have aliixed my signature. A- i y Y GEORGE E.
