GEM-MOUNTING.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed April 5, 1909. Serial No. 487,872.

T 0 all whom it may concern:

Be it known that I, JOSEPH J. BUsER, a citizen of the United States, residing at Freedom, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Gem-Mountings, of which the following is a specification.

My invention relates to improvements in gem mountings, and the leading object of my invention is the provision of a mounting which will revolutionize the present system.

of furnishing mountings and provide a mounting whlch will permit the insertion or application of the gem or stone by any person.

The custom or system in vogue is to furnish the mounting with the prongs unprepared, and when the stone or gem is selected, it is necessary for the jeweler to have the prongs prepared and fitted, and it is the purpose of my invention to overcome this objection which occasions loss of time and an expense as well, and to provide direct to the jeweler a mounting which will receive the gem or stone and which can be by the j eweler or an unskilled person instantly completed and sold.

With this object in View, my invention consists of a mounting having prongs constructed to receive and be bent down upon the gem to reliably secure the gem in proper position.

The invention further consists of a gem mounting embodying novel features of construction and arrangement of parts substantially as disclosed herein.

In order that the details of construction and the advantages of my improvement may be readily understood and appreciated, I have illustrated in the accompanying drawings a gem mounting constructed in accordance with and embodying my invention.

Figure 1, represents a side elevation of a complete finger ring having my novel and improved mounting. Fig. 2, represents a side elevation of one of the prongs embodying my mounting. Fig. 3, represents an outer face view or elevation of one of the prongs. Fig. 4, represents a side elevation of a stone in position with two of the prongs, one being bent or forced into engagement with the stone and the other being free or ready to be forced into engagement.

The letter A designates a finger ring provided with the series of prongs B, and while I have shown the invention in connection with a finger ring, I would have it understood that the mounting may be used in connection with studs, scarf pins, brooches, and in fact upon any class or character of jewelry where it would perform the desired function.

In carrying my invention into effect, I provide each prong B with the seat or platform C, upon which rests the stone, and with the extension I), having its outer face provided with the three tapering or beveled faces E which form the point or prong F, this construction providing a firm seat or support for the under edge of the stone and giving the prong the desired strength but permitting it to be easily bent down upon the upper edge of the stone to fasten the stone in position. To facilitate said bending of the prong I form in the inner face thereof the groove G which permits the tip of the prong to be more readily bent down upon the set and to make a tighter engagement therewith, as most clearly shown in Fig. 4.

It is evident that I provide a mounting which can be supplied direct from the manufacturer to the jeweler, and which will permit the stone or gem to be mounted by any person as it is slmply necessary to place the stone in position and bend the prongs down to secure the stone. apparent that my mounting in addition to saving labor and expense can be produced as cheaply, in fact more cheaply than the mountings in use, and is thoroughly efficient and practical in every particular.

I claim:

In a gem mounting, a series of prongs each having a shoulder formed near the upper end thereof and adapted to support the set, the portion of the prong above said shoulder being tapered on the outer edges to bring the same to a neat and ornamental It is also said groove being of substantially semi-cylindrical shape and being of such size that when the prong is bent upon the stone forming the set the edges of the groove 10 will make tight engagement with each other.

In testimony whereof I affix my signature, in presence of two Witnesses.

JOSEPH J. BUSER.
