Title: Improvements in sheet feeding apparatus for printing and like machines
IPC: B65H3/36
Filed: 1935-12-20
Abstract: 455,258. Feeding sheets. EHRIG, H., 34, Otto Schmiedstrasse, and KEILHAUER, U., 4, Zum Harfenacker, both in Leipsic, Germany. Dec. 20, 1935, No. 35381. [Class 100 (i)] Sheets are fed from a pile S to printing &c, machines by means of two sets of suction nozzles 10, 20 which move over different paths c, e indicated diagrammatically in Fig. 3, the sheets being transferred to the nozzles 20 at the intersecting position i and finally being transferred to a conveying device which is driven at different speeds according as it is desired to advance the sheets in an overlapping stream feed or to advance them one behind the other in spaced relation. The separating nozzles 10, 10<1> are carried by levers 11 which are given combined rising and falling and oscillating movements by means of rods 12 which are reciprocated by cams on a shaft 20, and levers 13 which are oscillated about pins 3a by cams on the same shaft 20 driven from the main shaft 80. The path of the nozzles 10 is indicated by the arrows c<1>, c<2>, Fig. 3, and in addition when these nozzles rest on the front of the pile the nozzles are turned about their rear edges r, so as to bend the front edge of the sheet, by means of suction-operated pistons 5i in cylinders 15, Fig. 10, arranged in the same air circuit as the separators. The pistons operate link-and-lever systems 17, 18, 19 which in conjunction with curved slots 16 at the upper ends of the levers 11 cause the nozzles 10, 10<1> to bend the sheet before it is moved from the pile. Blasts of air from nozzles p assist the separation of the sheets. The forwarding suction devices 20, 21, 22 engage the underside of the separated sheet at the position i, Fig. 3, the outer set 20, 20<1> being moved laterally outwards to straighten the sheet before it is brought into contact with the inner nozzles 21, 22<1>, 22, 22<1>. The nozzles 20 are moved outwards by pistons 5n in cylinders 25, Fig. 13, when the nozzles are closed by the sheet. The nozzles 20, 21, 22 are carried by oscillating levers 27 and cranked levers 28, operated by cams formed in discs 29, 291 on the shaft 70. The sheets are conveyed to the printing-machine by means of rollers and belts 30, 35 of known form driven at variable speed from the shaft 20 by means of elliptical gears 51, 53, or 41, 43. One set of elliptical gears is clutched to the shaft 70 by means of a clutch 71, or 72, the clutches being operated by levers from a common rod 75 which puts one clutch in gear and throws the other clutch out of gear so as to change from a stream feed to a feed of single sheets in spaced relation. This mechanism may be controlled by self-acting electromagnetic mechanism to stop the conveyer in the event of a misfeed, and forms the subject-matter of Specification 455,265.

Class 38(5) A switching key comprises a framework with one closed end in which is journalled a cam-barrel and an operating knob, spring members on the framework co-operating with flats on the barrel for holding it in certain positions, spring contact pile-ups arranged for operation by the barrel, and a stop on the framework co-operating with the cam periphery so as to allow certain axial and/or rotary movements of the barrel, variations in the shape of the barrel thereby producing various combinations of turn and push actions Normally, the barrel 12 is out of engagement with plungers 24, 25 so that contact pile-ups 4, 5 are not operated. Rotation of the barrel through 90 degrees clockwise in Fig. 1 causes a flat 22 thereon to operate plunger 24, the barrel being held in each position by springs 6, 7 engaging sloping flats 19, 20 on the barrel. The barrel may be moved axially in either end engular position-to cause operation of plunger 25 by a sloping surface 23 on the barrel. Axial movement in any other angular position, and rotary movement in any other axial position, are prevented by a stop 15 (with a step 16) and recesses 26, 28 and a flange 27 of reduced diameter in the barrel The springs 6, 7 return the barrel to its normal axial position by acting on the sloping surfaces 19, 20, but in Fig. 5, the barrel is retained in the operative position by engagement of the springs 6, 7 in a groove 29. The axial action may be stopped by omitting notch 26 and/ or 28 and the rotary action stopped by omitting to cut the flange 27. A light signal may be given by a translucent member passing through the barrel in a manner similar to that of Specification 620,465.
