FINGER-RING.

' SPECIFICATION forming part of Letters Patent No. 425,096, dated April 8, 1890.

Application led December 3l, 1889. Serial No. 335,493. (No model.) v

To all whom t may concern:

Be it known that I, RUDOLPH FOUCHS, of New York, in the county and State of New York, a subject of the Czar of Russia, have invented a new and useful Improvement in Finger-Rings, of which the following is a speciication. v

My improvement relates to means for securing stones in the heads of rings, and at the same time securing letters or other ornaments upon the stone.

I will describe my improvement in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a face view of a ring embodying my improvement, showing a stone anda letter thereon in position. Fig. 2 is a similar view, the stone and letter being removed, and showing the interior of the head. Fig. 3 is a view looking at the head from the under side, a portion of the ring being shown in section. Fig. 4 is a section of the letter or other ornament and taken on the line oc Fig. l. Fig. 5 is an edge View of a cam employed, together with means for causing the rotation of the same. Fig. 6 is a perspective view inverted of a stone employed. Fig. 7 is a face View of a key which may be employed to rotate the cam. Fig. 5 is drawn'to a larger scale than Figs. l, 2, and 3.

Similar letters of reference designate corresponding parts in all the figures.

A designates the ring portion of the ring, and B the head thereof. The head B is provided upon its upper side with a recess ct, which recess is adapted to receive a stone C. The under side of the head is closed.

Arranged about centrally, as here shown, within the recess a is a cam D. This cam in the present instance comprises two curved or circular portions d and two indentations or recesses d. The curved or circular portions d are opposite each other, as are also the indentations or recesses d.

Between the curved or circular portions CZ and the indentations or recesses d are proj ections d2, which projections operate as stops in a manner to be presently described. Each of the curved or circular portions d in this example of my improvement is provided upon its under side with a cam-surface d3, one of which is shown more clearly in Fig. 5. These cam-surfaces extend in reverse directions to each other. The stone C is provided upon its under side with a cavity c. When the stone is placed within the recess d, the cam D will extend into the cavity c. Perforations c are formed through the stone C and open into the cavity c.

E designates an ornament to be secured to the stone and to the ring. In the example shown this ornament consists of a letter of the alphabet. Upon the under side of this letter are formed or secured in this instance two prongs e, which prongs have formed uponV the sides thereof which face each other notches or indentations e. The metal of the prongs below the notches e constitute projections'on the prongs, which projections extend toward each other.

In securing the cam Within the recess d of the head I employ a metallic piece F, which metallic piece is shown as provided with a squared portion or neck f and a head f. The head f has formed in it notches f2, which notches are opposite each other, as shown. The cam D has formed in it about centrally a squared opening f3. or neck f of the metal piece F is passed through a suitable aperture in the bottom of the head B, and thence into the squared opening in the cam. It'is then upset at its inner end, so as to firmly secure the cam and the metal piece F together. By rotating the metal piece F ro tary motion maybe imparted to the cam. The piece F is rotated by a key G, provided with prongs g, which prongs may be inserted into the notches f2 for this purpose.

The stone having been placed within the head of the ring, the letter or other ornament is applied to the stone, the prongs e thereof being passed downwardly through the perfo rations c therein. The cam D has at this .time been rotated into the position shown The squared portion IOO or other ornament,andthe stone will thus be drawn down firmly and willbe tightlyT secured. The stops d2, when the cam is rotated sutileiently far, will contact with the prongs e, and thus prevent a too extended rotation of the cam.

It will be readily seen that by my improvement I provide a simple and ready means whereby both a stone and a letter or other ornament may be readily secu red upon a head of a rin g, and whereby they may be as readily released if for any cause their release should he desired.

Although I have shown and described two prongs provided with projections and en gag ing two cam-surfaces, Iwish it to be understood that I do not limit myself to this number, as I may use one or any desired number of each.

Ihat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a linger-ring, the combination, with a head provided with a recess, of a cam arranged in said recess and adapted to be rotated from the exterior of the head, a stone adapted to be received in said recess and provided with a perforation, a letter or other ornament, a prong upon one side of said letter or other ornament and provided with aprojcction, said prong being' adapted to be passed through the perforation in the stone and into such position that when the stone is within the recess in the head the projection on the prong may be engaged by the cam when the latter is rotated in order to lock the stone and the letter or other ornament in position on the ring, substantially as specified.

2. In a finger-ring, the combination, with a head provided with a recess, of a cam arranged in said recess and adapted to be rotated from the exterior of the head, a stone adapted to be received in said recess and provided with a perforation, a letter or other ornament, a prong upon one side of said letter or other ornament and provided with a projection, said prong being` adapted to be passed through the perforation in the stone and into such position that when the stone is within the recess in the head the projection on the prong may be engaged by the cam when the latter is rotated in order to lock the stone and the letter or other ornament in position on the ring, and a stop for preventing the too extended rotation of the cam, substantially as speciled.
