Specification of Letters Patent.

Patented Aug. 31, 1920.

Application filed March 3, 1919.v Serial. No. 280,336.

To all whom it may concern Be it known thatwe, ABRAHAM L. Emsorr and CHARLES BIRNBAUM, both citizens of the United States, and residents of the city of New York, borough of Manhattan,

county of New York, State of New York,

Drawings.

Fig. 2 is a vertical section of the same the section being taken as on the line 2-2 in Fig. 1.

Fig. 3 is a side view of the construction shown in Fig. 1.

Descrz'p time.

The present invention relates more particularly to improvements in the construction. of the cluster top disclosed in the Patent No. 1,238,721 granted to us August 28, 1917, to which patent cross reference is herewith made. In the construction disclosed in the said patent it will be observed that the terminals of the claws, each con nected with the so-called grid, at a point opposite the thinnest portion of the grid where the sockets approximate the outer perimeter of the said grid. It was our desire at the time to support this portion of the metal, and this was the method employed to do so. It has developed however, that through carelessness, or by force of circumstances, the socket is cut to a greater or lesser opening with the concomitant that the material between the sockets and the perimeter of the grid or top is dangerously In the present invention the grid or top Q is constructed from an integral metal and is provided with a series of sockets 10, in which gems are seated at convenient positions, and intermediate the various sockets are disposed bosses 11 which may be swaged or otherwise altered to spread over and assist in holding the various gems in the various sockets in which they are placed. The bosses 11 are highly polished to reflect light and thereby add to the scintillating effect of the mounting and the gems carried thereby.

Between the perimeter and each of the outer sockets 10, buttresses 12 are formed by increasing the metal at these points. As

seen best in Fig. 2 of the drawings, the buttresses 12 provide an extra thickness of metal which may be cut into by the mechanic while retaining sufiicient strength to avoid the weakening of the structure at this point, and the consequent opening of the socket to the detriment of possible loss of the gem carried therein.

The buttresses 12 extend between the bosses 11 which are disposed adjacent the perimeter of the top 9, and between each pair of said bosses which may be stated as being located at the greatest distance apart. Adjacent each of the bosses 11, the tines 13, of each of the arms 14, rest upon and are attached to the said top. The tines 13 are arranged in pairs and as shown best in Fig. 3 of the drawings, form a Y strut resting on each arm 14: in such manner as to cooperate with the buttresses 12 to provide a rigid and strong support for the top 9 and the gems carried therein.

As seen best in Fig. 2 of the drawings, when the gem such as indicated by the numeral 15, is seated in the socket 10 provided for it, the upstanding portion of the buttresses 12 may be forced over onto to engage the edge of the gem and thereby strengthen the hold of the metal upon the said gem to further insure the safety thereof.

It will be understood that the cluster mounting is preferably produced as an article of manufacture; the crown or underbody which comprises the arms 14, tines 13 and circlet 16, uniting the arms 14 at the lower ends thereof, the said crown being rigidly connected with the grid or top 9, but where it is found desirable, such construction may be constructed by that in which the crown and top are sold separately to the trade, tobe'united by the mechanic at the time of mounting the gems.

Claims.

1. As an article of manufacture, a' ring cluster mounting comprising a disk-like top having a series ofannularly disposed openended sockets juxtaposed to the perimeter of said top, the material of said top between the juxtaposed edges of each of said sockets and the perimeter of said top being raised above the contiguous surface of said top in line of those radii of said'top which are coincident *ith the radii of said sockets;

2. As an article of manufacture, a ring cluster mounting comprising a disk-like top lowing a series of annularly disposed openended sockets juxtaposed to the perimeter of said top, the material of said top between the juxtaposed edges of each of said sockets and the perimeter of said top being raised above the contiguous surface of said top in line of those radii of said top which are coincident with the radii of said sockets, and a crown for supporting said top, said crown having a series of upwarc ly and outwardly flared arms, each of said arms being provided at the extremities thereof" with bifurcated tines, the extremities of said tines being secured to said top in the spaces between saidsockets;

3. As an article of manufacture, a ring cluster mounting comprising a circular top having adjacent the perimeter thereof, and at regular intervals, raised portions, and a supporting crown therefor, said crown having downwardly converged arms, the terminals thereof attached to said top adjacent the ends of said thickened portions to cooperate therewith for forming a compression resisting structure.

4. As an article of manufacture, a ring cluster mounting comprising a circular top having adjacent the perimeter thereof, and at regular intervals, raised portions, and a supporting crown therefor, said crown having downwardly converged arms, the terminals th reof attached to said top adjacent the ends of said raised portions to cooperate therewith for forming a compression resisting structure, a series of gems mountedin said top, secured thereto by over-turned portions of said raised portions.

5. As an article of manufacture, a ring cluster, mountingcomprising a top having a series of open-ended soc rets formed therein adapted to hold gems, certain of said sockets being buiit up above the exposed surface of said top at the perimeter of said top in line with the radii thereof which radii are coincident with the diameter of said sockets.
