N. PEIE I IS. PNOTO-LITHOCHAFHER, WASi'llNGTON. D C)v UNITED STATES PATENT OFFICE.
DAVID UNTERMEYER, OF NEW YORK, N. Y.
NECKLACE-CLASP.
SPECIFICATION forming part of Letters Patent No. 230,510, dated July 27, 1880.
Application filed April 17, 1880.
To all whom it may concern:
Be it known that I, DAVID UNTERMEYER, oi the city, county, and State of New York, have invented a new and useful Improvement in Necklace-Clasps, of which the following is a specification.
Figure 1 is front elevation, partly in section, of the improvement. Fig. 2 represents one of the catch-plates. Fig. 3 is a sectional elevation taken through the line 00 m, Fig. 1.
Similar letters of reference indicate corresponding parts.
My invention is an improvementin the class of necklace-clasps which are provided with catch-bolts 0, whose outer ends have spherical knobs that serve as thumb-pieces, and also form ornamental terminals of this three-part bar A B B. t
The beveled innereuds of the bolt 0 pro- (ModeL) in the plates, as will be readily understood.
until their beveled ends enter the apertures 1 The catch-bolts and plates are held locked together by the action of the springs D D, which lie concealed within sockets B B.
To disengage the clasps from the necklace or neck-chain G the knobs of bolts (J are seized between the thumb and finger, and suificient tractile force applied to compress the springs D, or, in other words, to draw the heads of said bolts back into the sockets B Bagainst the tension of v the springs, thus releasing the catch-plates F.
What I claim is- The combination, with the necklace having the ring-shaped beveled catch-plates F, of the clasp formed of the part A, aligned sockets B B, and the bar A, which rigidly connects them, and the spring catch-bolts 0, having spherical ends or knobs, as and for the purpose specified.
DAVID UNTERMEYER.
