Abstract

640,179. Pens; pencils. INDUSTRIAL AUTOMATICS, Ltd., and BENKOE, I. Sept. 18, 1947, No. 25516. [Class 146 (iii)] A retractable pen or pencil comprises a tubular barrel 10 having in its side a slot 12 formed near each end with enlarged portions 13, 14, and a writing member 17 slidably mounted within the barrel so that its writing point 18 can be moved out of the barrel, the member 17 being held in either writing or retracted position by a spring plunger 22 mounted in the rear of the member 17 and which is formed with a neck 23 which is urged outwardly into either of the enlarged portions 13, 14 by a spring 21. The plunger is operated by a slider 25 which is depressed to disengage the neck 23 from one enlarged portion and then moved along the slot until it is urged by spring 21 into the other enlarged portion. The writing member 17 may be urged into retractor position by a spring.
