Title: Means for feeding sheets in sheet-feeding apparatus for printing presses, folding machines or the like
IPC: B65H5/24
Filed: 1929-09-06
Abstract: 331,435. Str÷mberg, N. G. A., and Widlund, G. W. Nov. 17, 1928, [Convention date]. Sheet separators and carriers; pile supports.- Sheets are fed to the front stops of printing, folding, or like machines from a stack 20 in the form of a continuous row of sheets which partly overlap each other on conveying bands 5 to which the sheets are fed in succession from a stack by means of sheet separating and forwarding devices which act underneath the row of sheets. The bands 5 pass over a tensioning-roller 7 and over rollers 1 carried by oscillating levers 10 which alternately raise the rollers 1 into contact with rollers 15 mounted in bearings carried by supports 13, and allow the rollers 1 to fall to the position shown in Fig. 3. The bands 5 also pass through rollers 2, 14, carried by the levers 10, and a number of sheets are constantly gripped between these rollers 2, 14. The rollers 1, 2 are in constant driving-connection with the main shaft 19 which is fitted with cams 18, 27, 32 for controlling the movements the levers 10, and other levers for controlling the movements of a suction separator 21 which engages the stack when the parts are in the position shown in Fig. 3, and air is exhausted from pipes 22, 23. The nozzles 21 are then raised by the action of the cam 32 on a bellcrank lever 28 which engages a roll 29 on an arm 30 fixed to the pipe 23, the pivotal motion of the pipe 23 causing the pipes 22 to raise the nozzle from the position alpha1 to the position alpha2. The rollers 1, 2 are now lowered by the action of the cam 18 and the roller 1 moves to the position shown in Fig. 3 while the separated top sheet of the pile is carried below the previously separated sheets to the position a3. The motion of translation of the nozzles is obtained by the action of the cam 27 on a roller 26 on one of the arms 24 in which the pipe 23 is carried. The vacuum is now broken and the separated sheet falls on to the bands, and the nozzles move forward to the position alpha4 while the rollers 1 are raised to grip the sheet between the rollers 1, 15, and the separated sheet then advances with the preceding sheets. A number of the overlapping sheets are gripped constantly between the rollers 2, 14. The nozzles 21 are then returned to the position alpha2, and are finally lowered on to the top of the stack.

Title: Improvements in self sustaining pulley blocks
IPC: B66D3/16
Filed: 1920-09-24
Abstract: 172,449. Willetts, C. Sept. 24, 1920. Winding pulley-blocks; geared pulley hoists; driving-gear; selfsustaining gear.-Driving-gear for pulley-blocks, cranes, &c. comprises two sets of worm gear, one set being either reversible or - irreversible and driving the pulley or drum in either direction for - hoisting or power lowering, while the other set is reversible and acts as a self-sustaining bear, as a means for permitting braked gravity lowering, and as a means for rapidly positioning the unloaded load chain or hook. As applied to a pulley-block, the apparatus comprises two wormwheels 1, 2, each formed integral with one of two chain sprockets 5, 6. The lower block carrying the load is suspended from two bights in the chain hanging from both sprockets, so that it can be manipulated by the rotation of either sprocket. Ordinary hoisting or lowering is performed by actuating the worm-wheel 1 through the medium of the hand chain-wheel 14. During the lifting movement a friction cone clutch 26 and ratchetwheel rotate together, but on the lifting-effort ceasing, the cone and ratchet form a selfsustaining gear for the load in so far as rotation of the sprocket 6 is concerned, and compel the worm shaft to overcome the friction of the cone clutch when the hand chain-wheel is rotated for lower. ing. The other worm-wheel 2, which also sup ports the load in part, is motionless during the operation of the worm-wheel 1, as the wormwheel is prevented from driving the worm 9 under the pressure of the load by a cone clutch member 15<a> engaging a non-rotating sleeve 22 to act as a self-sustaining brake for the sprocket 5. A lever 20 may be manipulated to move the member 22 axially to relieve this brake to permit braked gravity lowering, or rapid manipulation of the underloaded chain by direct hand haulage on the chain. A mechanical brake 30 mav be added to the apparatus to prevent the falling load from getting out of control.

Title: Improvements relating to automatic suction sheet feeding machines
IPC: B65H3/08
Filed: 1927-10-18
Abstract: 294,406. Jackson, L. Mellersh-, (Russell, C. S.). Oct. 18, 1927. Sheet-separators.-Sheets are separated from a pile D and fed to a printing-machine for office use, or other machine, by suction separators 18 carried by a reciprocating carriage formed of two parts E, F which normally move together but which are capable of relative movement, such movement being utilized to cause a rising and falling movement of the separators 18. The carriages E, F are guided in horizontal grooves 8 in the machine frames 1, 2, and the rear carriage F is attached to racks 12 which are engaged by oscillating pinions 31 on a shaft in gear with a reciprocating rack 33 operated by a lever 35, link 38, and crank 39 on the shaft of the printing-machine. As the carriages E, F move back from the printing- machine, a part fixed to carriage E engages an abutment 41, and the carriage Fcontinuing its advance causes cam members 27 connected thereto to move relatively to rollers 26 on vertically guided brackets 26 which carry the suction nozzles 18. The nozzles thus drop on to the pile D, and the top sheet adheres to the nozzles which are raised on the return of the carriage F. Springs 13 maintain the carriage E against the abutment 41 until the carriage F abuts carriage E in its forward motion. The nozzles 18 are connected by pipes 23 to a suction pipe 24 connected to a suction pump, the exhaust of which may be connected to an oscillating pipe 50 with nozzles 51 which are directed to deliver air blasts against the top sheets of the pile while it is acted on by the nozzles 18. The pipe 50 is turned by lever- and-link mechanism 56, 55, 54, 53, 52 operated by the action of the carriage F against the lever arm 56. To release the suction action on the sheet when it is engaged by the feed rollers of the printing-machine, a cam-surface 83 on link 38 acts on the spindle of a spring-closed valve 80, and connects the nozzles, 18 to the atmosphere at the desired moment. Pile supports.- The pile D is mounted on a table 7 which is automatically raised by a screw engaged by a rotary nut operated by bevel gearing from a shaft 62 geared to a ratchet or gear wheel 60 operated by a pawl 61 mounted on the oscillating lever 35. The pawl 61 is controlled by a pawl lever 68 connected to a lever 71 fitted with a feeler 73 in contact with the pile. When the pile is low the pawl 61 is caused to engage ratchet 60, but when the pile does not need replenishing the lever 68 allows the pawl to be out of engagement with the ratchet.
