Abstract: 733,506. Registering apparatus for continuous stationery. PETTY & SONS, Ltd. Dec. 21, 1953 [Feb. 3, 1953], No. 2970/53. Class 16. A writing machine incorporating registering apparatus for continuous stationery having punch holes at intervals therealong, comprises a writing support for the stationery, a retractable device having registering pegs thereon which is spring pressed to engage the holes in the stationery and a clamping device for clamping the stationery against movement when the pegs are in engagement with the holes to enable a section of the continuous stationery to be torn off while the adjacent stationery is held by the clamping means. Superposed continuous sheets of stationery 1 are guided over a writing plate 2 and under a cover plate 3 having an opening 4 through which the writing is effected, the stationery 1 being housed in the body of the box 5 and passing through an opening at the back of the plate 2. The stationery passes out between side guides 9 on a plate 7 or 7a fixed level with the plate 2 and under a plate 8 fixed to the underside of the cover 3. As shown in Fig. 4, registering pegs or pins 17 are mounted on an arm 11 which also carries the clamping device in the form of toothed plates 16 forward and to the side of the pins 17. The arm 11 is mounted on a bracket 12 by means of a pivot pin 14 having a coiled spring 13 urging the arm upwardly, the pins 17 passing through holes (10, not shown) in the bracket 12 and plate 7 to press on the stationery 1 and the toothed plates 16 then lying in slots 18 in the plate 7. When the pins 17 register with the holes in the stationery as it is pulled forwardly, they pass therethrough and enter holes (15a, not shown) in the plate 8 and recesses 15 in the cover plate 3 and the toothed plates 16 press the stationery 1 against a recess 19 in the top plate 8, when the stationery may be torn off against the outer edge of the top plate 8 along transverse lines of perforations. The arm 11 has a tongue 21 which lies under central notches in the plates 7, 8 so that when the stationery 1 is grasped between the notches, the tongue 21 is pressed downwardly by the fingers and pivots the arm 11 downwardly to release the stationery from the pins 17 and toothed plates 16. As shown in Figs. 7 and 9, registering pins 17a are carried by an arm 22 pivotally mounted on a support 23 which is pivotally mounted to the bracket 12a, the arm 22 being pressed upwardly by means of helical springs 29 and the support 23 being pressed inwardly against the bracket 12a by springs 30. The clamping device comprises separate knife- or pronged-edged plates 24 which are pivotally mounted at 24a on plates 24b fixed to the wall of the bracket 12a, to lie under turned over ends 9a of the plate 7. A rod 25 on the underside of arm 22 passes through slots 28 in side lugs 28a on the plates 24 and through slots 26 in side walls 27 of the bracket 12a, to move downwardly with the pins 17a on pressure on the tongue 21a of arm 22. When the pins 17a are first engaged in the punch holes of the stationery 1, the plates 24 are raised to the full line position of Fig. 7, just under the stationery. As the pull on the stationery is continued, the edges of the punch holes engage the pins 17a and pull them and the arm 22 forward against spring 30 so that the plates 24 are moved to the dotted line position of Fig. 7 to clamp the stationery 1 against slots 9b in the end plates 9a, when the stationery 1 may be torn off.
