Abstract
437,640. Pencil holders. CARTER, F., Brantwood, Firs Avenue, Ashton-under-Lyne. Aug. 27, 1935, No. 23922. [Class 146 (iii)] A propelling pencil comprises a part, such as the point, which grips the lead, and a spiral spring held by one end within another part of the pencil and which also grips the lead, the two parts being screwed together so that they separate when rotated in a direction which releases the grip of the spring, and come together when rotated in the opposite direction. Screwed into the body a, Fig. 3, is a holder c, to which is soldered a spiral spring d, one end of which is reduced so as to grip the lead. The lead may also be gripped by a second spring h, united to a cap f screwed upon the holder c, or by the split end g of the cap, which may be threaded internally. When the cap f is partly unscrewed, the lead is released from the grip of the spring d and drawn forward, and when the cap f is screwed back the lead is held by the spring d and slides through the spring h or portion g. In alternative constructions the cap f and body a may be integral and the holder c may pass freely through them and be screwed into the rear end of the body a; or, as shown in Fig. 4, the spring d may be held in a recess in the holder c, which is slotted at i to engage one end of the spring and turned over at k to retain the spring, so that the movement of both ends is limited, and forcing of the spring is prevented.
