Y. Application December 30, 1937, Serial No. 182,387 2 Claims. (Cl. 24-250‘) is, in a position permitting the opening of the My present invention relates to dress orna ments, and has particular reference to a new and clasp; Figure 3 is a view similar to Figure 2, showing improved type of clasp ornament. While I have disclosed my invention as applied to a clasp ornament, it is to be understood that as to certain phases thereof it is not. necessarily restricted to such application. ' It is among the general objects of my inven tion to provide, in a dress ornament of the clasp 10 type, novel means for locking the clasp so as to prevent its opening when it is in use, as when it is mounted on an article of apparel. While other types of locking arrangements for dress ornaments, and in particular for clasp or 15 naments, have heretofore been attempted, they are usually relatively complicated, inefficient, and unreliable in operation, cumbersome, unattractive in appearance, and relatively expensive to manue facture. Many of them are further of limited 20 utility because their locking mechanism is only operative in a few positions of the clasp and or nament members, so that the clasp may be safe~ one of the locking positions of the locking ar rangement; Figure 4 is an enlarged sectional view substan tially on the line 4——4 of Figure 3; and Figure 5 is a side view of Figure 1. In the drawing, l0 indicates one of the mem bers of a clasp ornament, while l2 indicates the 10 other member. One of these parts, as the mem ber l0, may be ornamentally contoured and sur faced and will hereinafter be referred to as the ornamental member; while the other member I2, which is intended to oppose the member ID in the clasping or clamping function, will herein after be referred to as the clasp member; and these parts are pivotally united by the arrange ment about to be described, whereby they may be brought into substantially parallel superposed relation as shown in full-lines in Figure 5 or into a spread or opened relation as shown in dot-and dash lines in Figure 5. The clasp member I2 is shown as provided with an inturned portion l4 having pintles or trun 25 nions l6 extending therefrom. The latter are adapted to be received within ori?ces 28 in the upstanding or out-turned ears I8 of a bearing plate 20 that is carried by-the ornamental mem ber 10, being fastened thereto in any suitable manner, such as soldering. These parts func to provide a locking arrangement for a clasp or tion as a hinge, uniting the members I2 and H1. nament that will be effective for all relative posi The parts so far described constitute a clasp tions of the clasp parts between their extreme ornament, the parts of which are united in limits of usefulness, as contradistinguished from 35 looking mechanisms that are effective at only hinged relation and are adapted for mounting, one or a limited number of relative positions of for example, on the edge of an article of wearing the clasp parts, whereby the range of effective .apparel.

It is among the more particular objects of my to pierce or press into the fabric, such as the 40 invention to provide in a dress ornament, such prongs 22. In order to lock the two members of the clasp as a clasp ornament, locking means in the form ornament in position after they have engaged a of a cam that may be readily moved into and out piece of material between them, I have shown an of its locking position, and which, when in look arrangement comprising an eccentric cam mem— 45 ing position, will resist tendencies to displace ber 24 rotatably mounted on a rivet 29 on the ex ment under conditions of normal wear. tension M of the member l2.

It is among the objects of my invention to overcome these objections by providing a locking arrangement in a dress ornament that is simple, effective, unobtrusive, and inexpensive to manu facture. 30 It is further among the objects of my invention 35 40 45 50 Figure 1 is a rear plan view of a clasp orna ment showing my invention applied thereto; Figure 2 is an end view, on an enlarged scale, 55 with the locking means in inactive position, that projecting outwardly therefrom. It will be observed that by turning the cam 24 about its axis, it may be caused to assume (a) a position such as indicated in Figure 2 55 2 2,118,411 in which its lobe portion 24' is out of engage ment with the plate 2%, thereby permitting the clasp member 92 to move freely about the hinge axis, or (b) a position shown in Figure 3 in which its lobe portion 24’ frictionally engages effectiveness only on material of predetermined thickness. It will be understood further that by proper the plate 23] and thereby limits the extent to tion between the contacting parts to prevent any possibility of the cam moving as a result of which the members i@ and 52 may be separated. Since the cam engages the plate ‘is on one side of the hinge as clearly appears from it is obvious that movement 10 Figures 1 and of the member 52 is limited only in one direc tion by the cam. Movement of the member i2 in the other direction, however, is limited by the fabric against which the ornamental mem ber l8 may be caused to press. In Figure ‘l, I have indicated the locking posi design, the pitch of the cam surface may be so proportioned that there will be su?‘icient fric pressure of the member l2 against it. This result may be secured by making the cam 21% of circular contour, as illustrated, although it will be under- 10 stood that I do not’ necessarily restrict myself to such circular contour.v In general, it will be understood that changes in the details, herein described and illustrated for the purpose of explaining the nature of my It can readily invention, may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is, therefore, intended that these de 20 be seen that the free movement of the members [0 and E2 in one direction is prevented either tails be interpreted as illustrative and not in a limiting sense. tion of the cam 2ft, such as it might assume when the clasp members HQ and i2 are in face~ to-face relationship, as shown. by engagement ti ereoi' with the fabric or with each other, while the cam prevents movement in the other direction. It will be understood that the locking position in Figure 3 is only one of many positions in which the locking function may be effected by the cam M, which may be moved into all intermediate positions between those shown in Figures 2 and 3 and also beyond those shown in Figure 3, and may perform this locking function in any of these positions. The exact position of the cam while performing its locking function depends , on the conformation of the clasp members and the dimensions and con?gurations of the parts that they embrace. It will be observed that in the locking position shown by way of example in Figure 3, the ears 26 are at approximately right angles to their position as shown in Fig ure 2, in which latter position the cam performs no locking function. It will be seen that one of the outstanding advantages of a clasp constructed according to my invention is that the locking function may . take place in a large number of relative posi tions of the ornamental and the clasping por tions, so that it is adaptable for use on fabrics or other materials of a thickness varying be tween wide limits, instead of being restricted, as many such devices are, to a few locking posi tions, whereby such a device attains its maximum Having thus described my invention, and illus trated its use, that which I claim as new and desire to secure by Letters Patent is-— > 1.
