Abstract

564,300. Typewriters. WILLIAMS, W. P. (Standard Register Co.). June 21, 1943,No. 10001. [Class 100 (iv)] A typewriter or tabulator, in which record material is advanced around a platen roll 7 by feed rollers 8, 9 or by feed pins 12, is constructed with a mounting for the assembly of the paper guide fingers 21 which can be readily moved into and out of operative relation with the platen roll 7 so as to permit of access to the roll 7 for interchanging purposes &c. In one form, Figs. 2, 4, the guides 21 are adjustably mounted on a bar 20 which connects a pair of spaced heads 17 formed with studs 18, 19, slidingly engaging slots 15, 16 in end plates 14 mounted on the platen carriage. The slots 16 are straight and end in notches 16<1>, and the slots 15 are in part straight and in part circular, so that when the frame is withdrawn bv a straight line movement so far that the studs 19 reach the slots 16<1>, further movement is of a pivotal nature about the studs 19, and the whole assembly is finally in the position shown in dotted lines in Fig. 2, and the studs 18 then rest in the notches 15<1>. In the operative position the assembly is held in place by latch arms 28 with notches engaging studs 31 on the fixed end plates, but the latches are released by other studs 32 on upward movement of the assembly. The guides 21 may be slotted where they register with the pins 12. In a modification, Figs. 8 and 10, the fingers 21 are adjustably secured to a slotted bar 33 provided at each end with discs 35 formed with central holes for engagement over studs 37 projecting from fixed mounting plates 38. One disc 35 may be engaged over a stud 37 and then moved reversely in an axial direction to engage the other stud. The heads are then secured by latch arms 39, which when released permit withdrawal of the disc 35 and with them the bar 33 and guides 21. The guides are held in operative position by the engagement of depending ears 40 on the underside of the bar 33 with studs 41 projecting from the mounting plates 38.
