Abstract
695,771. Drawing pins. HARRE, K. J. S. Dec. 17, 1951 [Dec. 16, 1950], No. 29545/51. Class 89 (ii) Drawing pins have sheet metal heads bent to an obtuse angle at 4 and pins 5 that are bent to a circular arc centred on the line 4. When the part 2 of the head is flat on the board the point of the pin is clear of the paper. Pressure on the part 3 causes the pin to enter along a curved path and pressure on the part 2 will effect its removal. The pin may be riveted to the head or punched out therefrom.
