Abstract: 196,291. American Sales Book Co., Ltd., (Assignees of Wiswall, W. J.). April 12, 1922, [Convention date]. Feeding webs. - In devices of the type adapted to receive and handle manifold pads, and especially pads employing continuous reversely-folded or zigzag strips of paper to provide sets of leaves connected end to end, the pad comprises a number of reversely-folded strips forming superposed sets of superposed leaves each of which is provided with feedcontrol apertures in definite positions thereon, the feeding-means being rendered inoperative by engagement with the apertures so as to enable the leaves of each set to be correctly registered in the writing position. The feeding-mechanism for the strips is mounted in the compartment 8, Fig. 2, of a casing, and in the hinged cover member 28 thereof. The cover carries a roller 27 mounted in spring-pressed bearings 29, Fig. 3, and is held in closed position by means of catches 39, 40 mounted on the casing and cover respectively. The catch 39 is carried by a pin connected by a member 43 to a push-button 41 which is acted on by a spring to normally hold the catches engaged. Rotatably mounted in the compartment 8 is a shaft 31 carrying feeding discs 33, 34, arranged to engage the strips in.line with apertures 21, Fig. 5, placed in definite relation to the forms 19 on the strips. The discs cooperate with the roller 27, one revolution of the discs being sufficient to feed the record-strips forward the length of one form. The discs are operated by a handle 35, the movement of which is limited to one revolution by a spring-pressed pin 36, which is pressed inwards to allow the movement of the handle to commence. Reverse rotation is prevented by a pawl-and-ratchet device 72, 73. The discs are connected by a bar 45 having a lug 46 near each end. Mounted in the disc 34 is a radially-disposed pin 47 which is projected by a spring but is normally held in retracted position by a spring-pressed catch 49. An extension 50 of the catch lies in the path of movement of the member 43, so that when the button 41 is pressed in to allow the cover 28 to be opened, the catch 49 is also released to permit the projection of the pin 47. When the record strips are being initially registered after passing over a writing plate 10, the cover 28 is raised and the pin 47 projected, the apertures 21 in the superposed forms 19 being placed thereon. The lowest strip 16 is directed downwards into a secret compartment 7, Fig. 2, and the hinged cover 12 thereof closed, so that the two upper strips 17, 18 are directed upwards by the lip 70 of the cover. The cover 28 is then closed, this action serving also to press in the pin 47 and enable it to be engaged by the catch 49, and to secure the cover 12. As the apertures 21 in the forms are in alignment with the discs 33, 34, the grip on the strips will cease when the apertures are opposite the discs. The upper strips tend to lag during the feeding so this is compensated for by the discs engaging the unpunched portions of the upper strips through the apertures in the lower strip to complete the movement. When the forward movement of the next set of forms is to be started, the lugs 46 on the bar 45 grip the unpunched portions of the strips and move them forward a sufficient distance to enable the discs 33, 34 to come into operation.
