CHARLES It. TOST, OF CENTERDALE, RHODE ISLAND, ASSIGNOR TO THE HADLEY COMPANY, OF PROVIDENCE, RHODE ISLAND.

RIBBON-BRACELET CLASP.

Application led October 9, 1924. Serial No. 742,520.

To all whom it may concern:

Be it known that I, CHAnLns It. Tosr, a citizen of the United States, residing at Centerdale, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Ribbon- Bracelet Glasps, of which the following is a specification.

'Ihis invention relates to certain new and useful improvements in ribbon bracelet clasps and the primary object thereof is to provide a clasp in which both the male and female members are of simple and economical construction and are each of integral formation.

A further object of the invention is to provide a clasp wherein the male .member has a four-point bearing in the female member and which also has improved spring properties for enabling connection to and disconnection from the female member.

The invention has still further and other objects which will be later herein set forth and manifested in the course of the following description.

In the drawings Figure l is a plan view of the invention, the parts being connected and applied to a ribbon bracelet;

Figures 2 and 3 are sections on lines 2-2 and SH3 of Figure 1 respectively;

Figure Il; is a plan view of the blank from which the male member is formed;

Figure 5 shows a plan and side edge elevation of the blank in the first step of making and Figure 6 shows like views of the finished male member.

In proceeding in accordance with the present invention a. blank 1 is employed from which the male member is formed, the blank being first subjected to the action of dics which strike-out therefrom a substantially square head 2, the punch at the same time splitting each of the four corners at 3 so as to enable independent spring action of each of the four sides of the head. The

four sides of the head are each further curved inwardly or given a somewhat V- shape as indicated at l so as to provide a neck. If desired the entire corners may be cut away so as to increase the spring action. The next step resides in cutting away the blank on opposite sides of the center thereof at 5 leaving the head supported on abar 6 that is connected at its ends to the blank body l, the bar 6 being olilset from the plane of the body l to accommodate the ribbon R. The female member 7 has a square opening 8 to receive the hea-d 2 which latter snaps through the opening 8.

From the foregoing it will be seen that the head 2 engages each of the four walls defining the opening 8 and consequently the parts are effectively hel-d against relative turning movements and lin addition a more effective clasping action is had due to the fourpoint engagement of the head with the walls of opening 8.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In a clasp, a female member having a rectangular opening, and a male member composed of a plate formed with a pair of spaced openings disposed on opposite sides of the center of the plate and each spaced at each. end from the adjacent ends of the plate to provide a central bar, the bar being olf set to lie in a plane in front of that of the plate, and a rectangular head integral with the plate and located in spaced relation to the sides and ends of the bar, and having cach of its four corners slittcd, the slits terminating at the junctural points of the head and bar so as to leave the latter of solid formation, each of the head sides being of V-.shape with the apices of the Vs located centrally between the top and bottom of the head.

In testimony whereof I have signed my name to this specification.

CHARLES R. TOST.
