Application filed April 11, 1904. Serial No- 202.482 (N model.)
T0 at whom, itvnay'oonccrn: 1
Be it known that we, WOLF OAHN and PHILIP H. LONG, citizens of the United States, and residents of Newark, in the county of 5 Essex and State of New Jersey, have made and invented certain new and useful Improvements in Olasps, of which the following is a specification.
Our invention relates to an improvement to in clasps, and more particularly to that kind or style thereof usually known and referred to as necktie .clasps or fasteners employed for the purpose of securing the tie to the shirt-bosom, the object of our invention being to produce an article of this kind or character which shall be simple in construction, effective in use, and which at the same time shall be cheaper to manufacture than those commonly employed for the same purpose.
With these and other ends in view our invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is a View in side elevation of our improved clasp, the same being shown in its closed adjust ment. Fig. 2 is a longitudinal sectional view of the same, the clasp being shown in its open adjustment. Fig. 3 is avertical sectional view taken on the line 3 3 of Fig. 2 looking in the direction as indicated by the arrow. Fig. 4 is a view in side elevation of-the upper plate detached. Fig. 5 is a top plan view of the lower or spring plate.
As shown by the drawings, the clasp consists of but two part-s-namely, the upper or top. plate A and the lower or spring plate B, the forward end of said upper plate A being 4 provided with the downwardly projecting teeth a and its sides with the ears 6, said ears having formed therein an opening 0 of the shape shownthat is, of somewhat the shape of a heartthe point (Z acting as a pivot or bearing for the lower or spring plate B in,
v opening or closing the clasp, as hereinafter described. The lower or spring plate B has also formed on its forward end teeth a, which when the parts are properly assembled and the clasp closed mesh with the teeth a, as shown in Fig. 1, the sides of the plate being provided with the lugs la, adapted to pass through the openings 0 in the ears 6, the extreme ends of said lugs being bent down wardly in order to prevent the two plates from becoming disengaged. The central portion of the plate B is slit and bent upwardly to form the spring-finger contact, asshown in Fig. 1, or, in other words,
to retain the clasp in its closed adjustment. If pressure, however, is exerted upon the rear ends of the plates, the forward ends thereof will open or separate, as illustrated in Fig. 2, the lugs 7L rocking upon the bearing points or pivots cl, the curved portion of the springfinger O being-slightly forced down through the central opening' of the plate B. When the pressure is released, the tension of the spring-finger C will immediately separate the rear ends of the plates A and B and close the forward ends, the teeth a a being brought into mesh, as before described.
In order to sufliciently stiffen and strengthen the plate B, and especially the rear end thereof,
we provide the same with the rib 7a, extending entirely around the plate, parallel with the outer edge thereof, it having been shown in, practice that unless the plate is so formed it is liable to bend in opening the clasp against the tension of the spring-finger C.
It will be understood from the foregoing that the clasp is simple and economical to construct, and consisting, as it does, of but two pieces or parts the latter are easily and readily assembled.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is i A clasp consisting of two plates one of which of said ears having formed therein a slot into in its closed adjustment, substantially as de- Which extends a portion of the metal forming scribed.
a pivot, the other of said plates being also Signed at Newark, in the county of Essex provided with teeth meshing with said former and State of New Jersey, this 8th day of April, 5 teeth, and With lugs on said sides, the latter A. D. .1904.
