Abstract

185,534. Cohen, A. June 15, 1921. Pins, drawing, carpet, and drugget.-A drawing-pin &c. comprises a holder and a pin proper and is so constructed that the pin can be temporarily locked in the holder for use, or removed therefrom. In one form, a metal bushing a and cap b are drilled centrally to accommodate a pin c and screw-threaded for interengagement at e. In another form, the holder has a split conical shank which is pressed on to the pin by an encircling ring. Modifications in which the pin is held in position by a set-screw and in which the pin itself is screwed into the holder are shown and described.
