- STUD FOR SPRING PRESSURE FASTENERS 0R BUTTONS. APPLICATION FILED SEPT. l2. m1.

VICTOR MARENDOVVSKI, OF PARIS, FRANCE.
Specification of Letters Patent.
STUD FOR SPRING-PRESSURE FASTENERS OR BUTTONS.
Application filed September 12, 1917. Serial No. 190,933.
To all whom it may concern:
Be it known that I, VIoroR MARENDOVVSKI, mechanical engineer and patent agent, of 34- Boulevard Voltaire, at Paris, Department of the Seine, France, citizen of Poland, have invented certain new and useful Improvements in Studs for Spring-Pressure Fasteners or Buttons; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to a new form of stud heads for pressure buttons. There are already known studs which are formed by the folding or by the stamping of a metal strip to be introduced by pressure in the socket.
The invention consists to give to the elongated head of the stud button a shapeof an M with rounded parts for the purpose of increasing, by the multiplicity of the flexible points, the working of the studs spring.
In the drawing, the Figure 1 shows, in elevation, a form of execution and the Figs. 2 and 8 show, 1n elevation and in plan, a
modification of the improved head of the stud.
The elongated heads of the studs having two lateral legs 4 connected to the basis 1, instead of being simply open or closed at the top, are curved once or twice in the mid die as in 2 and 3 so as to present the shape of an M.
By that shape of execution of the head the number of the elastic points is larger so that the head works better and has a better elasticity.
I claim 1 A stud for spring pressure buttons or fasteners having elongated heads composed of two lateral legs connected to the basisand curved in the middle in the form of an M with rounded parts for the purpose of in,- creasing, by the multiplicity of the points of flexibility, the working of the studs spring, substantially as described, illustrated and set forth.
