ITED STATES PATENT OFFICE 2,120, 308 BRACELET’ OR OTHER JEWEL Georges Bezault, Juvisy, France, assignor to Car tier, 1110., New York, N. Y., a corporation of New York Original application February 16, 1937, Serial No. 125,955. Divided and this application March 26, 1938,v Serial No. 198 ,224. In France Febru~ my 25, 1936 4 Claims. The present invention is a bracelet or other jewel having a plurality of jointed elements ca (Cl. 63—9) edges limiting the various jointed parts have been marked in strong lines; pable of moving angularly with respect to one Figures 3 and 4 are detail vie 5 . another when it is desired to put on or remove the jewel, this application constituting a division of application Serial No. 125,955, ?led February 16, 1937 on “Bracelets or other jewels.” rIhis bracelet has, in the state of rest, the general shape of a split annular element and the jointed parts thereof are associated with springs which, in the position of rest, determine the rela tive positions of said parts, in such manner as to ensure that the whole assumes this form of a 15 split annular element. However, it is possible to pivot the jointed parts of the bracelet with respect to one another against the action of said springs, so as to move the ends of the bracelet away from each other, and thus permit of putting 2 O on or removing said bracelet, which is not possible - in the case of rigid annular split bracelets. Such a bracelet can be ?tted exactly to the size of the wrist or ankle, Without involving any difficulty for putting on or removing said 25 bracelet. In a preferred embodiment of this invention the hinges are constituted by male and female surfaces of revolution assembled‘ around a com mon axis of revolution and flush with the external 30 surface of the bracelet. With such an arrange ment, it is possible, by carefully working the parts, to wholly conceal these joints in the position of rest of the bracelet. If said bracket is too big or includes ornaments projecting to a considerable 3 5 distance from the outer surface thereof, and if, consequently, it is difficult to make use of the arrangement just above set forth, the limited value of the relative angular displacements of the contiguous parts will however permit of hiding 4 O the spaces between said parts by means of cover ing pieces easy to make. Therefore, in all cases, it is possible to give the bracelet, if so desired, the aspect of an annular element made of a single piece. Other features of the present invention will result from the following detailed description of some speci?c embodiments thereof. Preferred embodiments of the present inven tion will be hereinafter described with reference 50 to the accompanying drawing, given merely by 45 way of example, and in which: Figure 1 is a diagrammatic plan view of a bracelet made according to the present inven tion; 55 Figure 2 is an elevational View in which the showing, re spectively, two adjacent jointedWe parts of the 5 bracelet; Figure 5 is a partial sectional view of the bracelet in the state of rest; Figure 6 is an analogous view, the bracelet be ing deformed so as to permit of putting it on or of removing it; p 10 Figure 7 is an elevational vi ew, on an enlarged scale, with parts cut away, of a detail of the pivot ing connection of two adjacent parts and of the arrangement of the springs; Figures 8 and 9 are diagrammatic plan views 15 relating to modi?cations. As shown by Figures 1 to 7, the bracelet in cludes a plurality of parts I, 2, 3, 4, 5 pivoted to one another through axes 6 engaging in knuckles provided in the common edges of adja~~ 20-“ cent parts. Thus, in the example illustrated by the drawing, one of the parts or elements of'the bracelet (Figure 3) includes a central knuckle 1 adapted to fl t in a recess 8 provided in the edge of the other element (Figure 4) between , two 25 knuckles 9. The two elements connected together by the insertion of assembling pin 6 into knuckles ‘l and 9 can thus pivot with respect to each other. The knuckles 9 of one of the elements are re cessed at Ill transversely to the pivoting axis and 30 corresponding recesses are provided at H in the other element. In these recesses are engaged spring blades l2 which have, in the state of rest, a curvature corresponding to that of the annular shaped bracelet and which apply against one an- 35 other the inner faces (such as 1a and 8a, Figures 3 and 4) of the ridges of the adjoining elements. With this arrangement, the various jointed ele ments occupy, in the state of rest, relative posi tions such that the bracelet has the appearance 40 of a split annular structure, as shown by Figure 1. By carefully machining the ridges of the elements, and possibly by providing a suitable ornamenta tion of the surface of the bracelet, it is possible to conceal these ridges. 45 In order to put on the bracelet or to remove it, it su?ices to move the end elements I and 5 away from each other, which produces relative angular displacements of the elements of the bracelet against the elastic action of the springs. 50 Left to itself, the bracelet returns into its initial shape. In order to avoid exaggerate relative rota tions of the elements, which might cause the springs to break, it is advantageous to provide, on the ridges of the joints, projections such as 55 2,120,308 2 l3 (Figure 3) engaging in holes l4 (Figure 4) the edges of which parallel to the pivot pin form abutments for projections l3. In the above described embodiment, the hinge surfaces are constituted by male and female cyl inder portions jointed about their common piv oting axis 6 and tangent to the external surface of the elements (see Figures 1 and 6), which facilitates the concealment of the ridges between 10 contiguous elements. But it may occur that, in the case of very big bracelets or of bracelets the ornamentation of which projects to a considerable distance from the body thereof, this kind of articulation can 15 no longer be employed. In this case, as shown by Figure 8, I provide, in the state of rest, angles 15 between the contiguous elements so as to per mit of their pivoting with respect to one another despite the eccentric position of the pivoting 20 axes. However, these angles are the smaller as the number of articulated elements is greater. When they are small it is easier to conceal them by means of covering elements such as I6 (Fig ure 9) the cheeks 16a of which are pivoted about 25 pins Gor rigid with one of the contiguous ele ments, whereby the bracelet keeps the ap pearance of a structure made of a single piece. If a watch is carried by one of the elements of the bracelet, the latter constitutes a wrist watch 30 the ?xation of which to the arm is both simple and original. Of course, the idea of dividing an annular structure into a plurality of jointed elements pro vided with return springs can, according to‘ the 35 present invention, be applied to collars or other jewels or ornaments. In a general manner, while I have, in the above description, disclosed what I deem to be prac tical and efficient embodiments of the present invention, it should be well understood that I 40 do not wish to be limited thereto as there might be changes made in the arrangement, disposi tion and form of the parts without departing from the principle of the present invention as comprehended within the scope of the appended claims. Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is: 1. An article of jewelry, and especially a bracelet, which comprises, in combination, a series of chambered elements pivotally connected to one another and having openings in the joints between them, and leaf springs positioned Within 10 certain of said elements and extending through the said openings into adjacent elements and bearing against the walls of the latter to urge said elements toward their relative positions for which the whole assumes the general shape of a 15 split annular structure. 2. An article of jewelry, and especially a bracelet, which comprises, in combination, a series of chambered elements pivotally connected to one another about parallel axes so as to form a 20 jointed band with openings in the elements at the joints, cooperating stops formed on the ad jacent ends of the respective elements arranged in such manner that when said respective stops are in contact, the whole of said elements forms 25 a split annular structure, which'can be opened by forcing the ends thereof from each other, and leaf springs positioned within certain elements and extending through said openings. into adja cent elements and bearing against the walls of 30 the latter for urging said respective stops against each other. , 3. An article of jewelry according to claim 2 further including covering devices carried by each of said elements and arranged to bridge the 35 joint formed between the outer parts of said ele ments when said jewel is in the position of max imum curvature. 4. An article of jewelry according to claim 2 in which each spring is carried by one element and acts directly upon the inside surface of the adjacent element. GEORGES BEZAULT.
