OF BROOKLYN, NEW YORK.
IMPLEMENT FOR SETTING DIAMONDS iN lhIE'T'AL.
SPECIFICATION forming part of Letters Patent No. 531,731 dated January 1,1895.
Application filed August 8, 1894. Serial No. 619,349. (No model.)
To aZZ whom it may concern.-
Be it known that I, RUDOLF MARQUART, a subject of the Emperor of Germany, residing in the city, county, and State of New York, have invented a new and useful Improvement in Implements for Setting Diamonds in Metal, of which the following is a specification.
Diamonds are set solidlyin metal for various purposes in the arts and manufactures.
I-Ieretofore in thus setting diamonds and other similar hard stones, the metal wall around the stone was pressed over upon the surface of the stone to hold the same in place by a tool pressing upon and working the metal at only one spot at a time. Consequently the stone had to be independently held at other and opposite points to prevent it being dislodged by the very actof setting.
The object of my invention is to operate upon the metal at points all around the stone to be set and press the metal simultaneously at a multiplicity of spots over upon the stones by degrees or stages until the operation is fully completed.
My invention relates particularly to setting diamonds in saws or metal forms for shaping and cutting stone, and in carrying out my invention I employ a device like pinchers having jaws and handles pivoted together. One jaw carries a plate parallel with it and in which is a series of circularly arranged inclined holes receiving circularly arranged inclined rods. One jaw supports the piece of metal with the stone to be set and the other jaw bears upon the diverging ends of the circularly arranged rods to press their other and converging ends against the metal around the stone to force the metal over upon the stone to hold it in place. I prefer to make a concavity in the jaw acting upon the diverging ends of said rods so that the bearing may be upon their flat ends, and I prefer to make each of said rods with a head and the plate with a socket for each rod and ahelical spring around each rod between the head and base of the socket to return the rods to a normal position after pressure.
In the drawings, Figure l is a side elevation illustrating my improvements. Fig. 2 is a plan View of the same, and Fig. 3 is a cross section at as x of exaggerated size.
The jaw a and its handle a and the jaw b and its handle I) are pivoted together at 2, the jaw 19 and handle 1) extending through a mortise in the jaw a and handle a. The plate oconnected to and supported by the jaw a projects between the jaws a b and is parallel to the jaw a and near its outer end is a series of circularly arranged inclined sockets 3 and holes 4 which receive the circularly arranged inclined rods d. Each rod cl is preferably provided with a head (1 above the plate 0 and with a helical spring e that surrounds the same between the head and the base of the socket 3, the office of which is to lift the rod toward the jaw b.
The flat ends of the rods cl are at right angles to the axis of the rods and the under side of the jaw bis preferably concaved or hollowed out so that its surface will take an even bearing on the diverging ends of the rods d.
The inner face of the jaw a is adapted to support the piece of metal h in which is a cavity receiving the diamond t' to be set therein, and the converging ends of the rods 61 hear upon the surface of the metal around the stone and pressure upon the handles a. 1) brings the jaw Z2 down upon the rods (Z and exerts a pressure simultaneously upon the rods causing them to act upon the wall of metal all around the stone to press the metal over against the surface of the stone.
By progressively turning the metal block it and by slightly shifting the said block and by repeated pressures the metal is gradually worked up to and upon the stone and the stone set securelyin place. This is especially the case when the metal is heated so that it is somewhat softened.
By this device the metal all around the stone both at the edge of the stone and adjacent thereto is simultaneously worked up so that it is not necessary to hold the stone at any place during the setting operation.
I claim as my invention- 1. In a device for setting diamonds in metal, the combination with jaws a, b and handles a b pivoted together, of a series of circularly arranged inclined rodsd, the plate 0 forming a guide and through which said rods pass,
I yielding 'nieans for acting on said inclined arranged inclined rods d, the plate a forming a a guide and through which said rods pass,
heads d upon therods d and helical springs 6 around said rods between the same and the x 5 plate c, the jaw a supporting the metal carrying the diamond to be set and the jaw I) having a concavity and acting upon the ends of the rods 61, substantially'as andfor the purposes set forth. I
Signed, by me this 18th day'of July, A. D. 189-1.
