Abstract: 694,102. Autographic registers. WAECHTER, H. J. Feb. 1, 1950. [March 11, 1949] No. 2647/50. Class 16. [Also in Group XIX] An autographic register. in which a strip of connected manifold forms is fed serially across a writing platen so that single forms are successively exposed includes means for arresting the movement of the strip across the platen when each successive form is brought in register with the platen comprising a pair of pins adapted to be moved into engagement with a pair of holes in the form, one of said pins having a head and a relatively narrow edge on its top face formed at that portion of the head with which the hole in the moving form first comes into alignment, means for interlinking the pins for coactive movement into and out of registry with the holes, spring means for urging the pins toward the position of engagement with the holes, the said narrow edge on one pin being adapted to ride a surface of the form strip, the other of said pins being held in spaced relationship to the moving strip by said interlinking means when the strip riding pin is in contact with the said surface of the strip, whereby the said narrow edge of the first pin is free to enter a hole in the moving form immediately a portion of the area of the hole corresponding to the area of the narrow edge is aligned with said pin. The manifold forms 22, Fig. 2, are kept in a compartment 21 in the register casing 15 and are fed serially round a bar 24 over a writing platen 25 below an opening 31 in the casing lid 19. Two arms 34, 35, Fig. 4, are pivoted at 36 and 37 respectively to a bracket 38 fixed to a platform 20. The arms 34, 35 are connected by a spring 39 so that pins 26, 27 carried thereby are urged upwardly to pass through aligned holes 28, 29, 30, 32, 33, Figs. 4 and 5, in the platen 25, the manifold form on the platen and the lid 19 of the casing respectively. The arm 35 has a stud 45 which projects through an oblique slot 46 in the arm 34 and ends in an enlarged flange 47 which enters a slot 48 in the bracket 38. The pin 26 extends at 51, Fig. 6, towards the front of the casing and has a socket 50, 52, whereas the pin 27, Fig. 8, at its top slopes down to the front of the casing to provide a form engaging surface edge 56. In operation when the operator has finished writing on the form on the platen 26 he depresses the pin 26 by a pencil or the like so rocking the arm 34 about its pivot. The stud 45 rocks the arm 34 and the pin 27 is lowered, Fig. 5. The operator then moves the pencil towards the front of the casing so that the front edge of the used form projects sufficiently therefrom to be gripped and pulled out. The edge 56 of the pin 27 rides on the surface of the succeeding form which is arrested when the pin 27 enters the hole 30 therein. By reason of the shape of its top the pin 27 will enter the hole 30 in stages so that the possibility of the operator pulling out more than one form is reduced. The pin 26 serves to align the form on the platen by entering a second hole 30. Specification 694,103 is referred to.
