Abstract

572,123. Propelling pencils. EGERTON & CO., Ltd., J., and MORGAN, H. March 20, 1944, No. 5110. [Class 146 (iii)] A pencil of the kind described in Specification 457,589 is constructed so that the lead c is a push fit in a spring tube b of the conical point section a, and the pencil is advanced by pushing in a knob l against the action of a spring k to actuate the lead carrier tube f which is formed with long slits g, and short slits h equal to a quarter the length of the tube f and formed with inclined ribs i acting as jaws. A sleeve j, which has a limited movement in a recess n in the section a, causes the jaws i to grip the pencil to advance it as the knob l is pressed inwards, and the grip is released when the sleeve reaches the left-hand end of the recess n. On the return of the knob, the pressure of the jaws is put on when the sleeve j reaches the right-hand end of the recesses n, so that in use the lead is held firm by the tube b and the jaws i.
