667,235. Pencil holders; erasers. SHELLEY, J. W., and EVERSHARP, Ltd. Nov. 25, 1949, No. 30302/49. Class 146 (iii). In a propelling pencil similar in general construction to that described in Specification 489,881, the magazine 31 and lead guide tube 32 are formed from one piece of tubular metal, drawn or swaged to form the lead guide tube, such that a shoulder 34 between the tube 32 and magazine 31 provides the bottom of the magazine and a seating for one end of the return spring 46. The magazine 31, guide tube 32, spring 46 and a guide bushing 11 for a constricting member 52 are a unitary assembly slidable into position in the barrel and retained therein by engagement of cooperating screw means on the guide bushing and the barrel tip. A clutch having a head 38 fitting into an expanded socket 32a of the tube is retained by an inwardly bent lip 32b engaging the underside of the head 38. The bushing 11 is retained cn the guide tube by a collar 11a on the bushing operating with the upper end of the socket 32a. A rubber eraser 55 is retained within a reversible cap 64 by a socket 55a having spring tongues 55b for frictional engagement with the inner surface of the cap.
