Abstract

567,455. Typewriters. WILLIAMS, W. P. (Standard Register Co.). Sept. 14, 1943, No. 15075. [Class 100 (iv)] To enable platens of various lengths to be used in typewriters, such as print in conjunction with an entire line or group of type, interchangeable split platens 21 are used, each formed of a semi-cylindrical hard metal or moulded plastic material 22, and an outer rubber or like cover 21a, 21b formed with tips 24 which overlap marginal rabbets in the cores. One core 22 is formed with projecting tongues 25 bounded by edges which are respectively radial of and tangential to the platen when the parts 22 are assembled by inserting the tongues 25 in correspondingly-shaped recesses 26 in the adjacent section. The platen is assembled on the shaft 1 of the typewriter by the aid of a sleeve 6 formed with notches 7 for receiving detents 18 which hold in position a two-part thrustcollar formed of two parts 19, 20 screwed together to permit of fine adjustment. The thrust-collar controls the axial position of a clamp head 8 formed with angular ribs 28 for engaging grooves of similar shape in the ends of the cores 22. The heads 8 are formed with apertures for receiving pins 9 for advancing the record strips, the pins 9 being controlled by cams 11 in a manner similar to that set forth in Specification 471,531. Specification 408,125 also is referred to.
