Title: Improvements in machines for casting and composing movable type for printing
IPC: B41B7/00
Filed: 1936-07-20
Abstract: 473,097. Type - making machines. DEVEZE, F. July 20, 1936, No. 20077. Convention date, July 19, 1935. [Class 100 (iii)] Single - type composing and casting machines.-In machines of the kind described in Specifications 10174/12 and 199,011, [both in Class 100 (iii)], the matrix - holder is shifted, in order to bring different groups of matrices into use, by automatic means brought into action by the depression of two keys. Four groups of matrices 201, Fig. 1, are mounted in a holder consisting of two discs 198 connected by a square shaft 200. The holder is rotatably mounted in a frame 199 carried in guides 204 on the machine frame 1. Change of the matrices is effected by a lever 207, Fig. 2, which is rocked by the rotation of a crank 206. The movement of the lever to the right rocks an angle-lever 209 and withdraws a locking-dog from one of a series of notches a in a disc 213 secured to the shaft 200. The lever 207 also rocks a lever 211 carrying a pawl 212, which is thereby drawn back and engages in one of a series of recesses b<1> on a disc 203 secured to the shaft 200. When the lever 207 moves to the left, the pawl 212 rotates the matrix-holder through an angle of 90‹, so as to bring another group of matrices into casting position. The locking-dog on the lever 209 is then caused by a spring to enter another notch a. To avoid shock when the holder is arrested, a spring-pressed lever 218 engages notches in a disc 220 on the shaft 200. The lever is rocked, in order to release the disc, by the action of the lever 209. The matrix group in use receives both a rotary and a reciprocating movement in known manner. When a change is to be made, the reciprocating movement is arrested by the action of a pawl on the recording-drum described in Specification 199,011, which is set by the depression of a key. A second key sets another pawl, which effects the closing of a one-revolution clutch and the rotation of the crank 206.

Title: Method and apparatus for pnuematic feeding of several cigarette making machines with cut tobacco
IPC: A24C5/39
Filed: 1959-06-12
Abstract: 924,147. Feeding tobacco. K. KÍRBER. June 12, 1959 [June 14, 1958], No. 20189/59. Class 130. [Also in Group XXX] In a pneumatic system for feeding tobacco to several cigarette-making machines the tobacco is fed by an elevator conveyer 2a upwardly to delivery points 6, 7, feeding the pneumatic conveyer pipes, the tobacco being sucked off directly at the upper end of the conveyer. The conveyer 2a comprises a number of individual toothed conveyer belts 2a each of which feeds two or more delivery pipes 6, 7, which lead to the delivery boxes 13, 14 of cigarette-making machines, which boxes are connected to suction pipes 15, 16, fed from a common suction pipe 17 under the control of throttles 13a, 14a, operated by electromagnets 18, 19. Each belt 2a is driven from a continuously operating motor 9 through a clutch 10 operated under the control of switches 20, 21, which close when a predetermined suction is achieved in the pipes 6, 7. Fig. 3 shows an electrical circuit for the automatic sequential feeding of the boxes 13, 14. Closing of a time-operated switch 25 actuates a relay 29 to energize a rotary selector switch 31 which rotates to close switch 31b which energizes a relay 27 to activate solenoid 18 to connect pipe 11 to the suction source 17. When sufficient suction develops in pipe 11, switch 20 closes to actuate relays 34, 35, to energize the operating solenoid 36 of clutch 10 and the belt 2a starts to feed into the pipe 11. After a predetermined period, delay switch 33 breaks the circuit of coil 36 to stop the belt 2a and after a further period sufficient to ensure emptying of the pipe 11, delay switch 32 breaks the circuit of relays 29 and 27 to de-energize coil 18 and close the suction valve 13a in pipe 11, terminating the feed. When a second time-operated switch 26 is closed, relay 30 is actuated to energize the selector switch 31 which rotates to close switch 31c, actuating the relay 28 to energize the operating coil 19 of suction valve 14a in pipe 12, the feed through which is controlled by the suction switch 21 and delay switches 32, 33, in the same way as for pipe 11. After termination of the feed through pipe 12 the circuit is inoperative until the time switches 25, 26, initiate another feeding cycle. The elevator 2a may comprise five individual conveyer belts each supplying two or three pneumatic feed pipes, all of which are operated in sequence and the switches 20, 21, may control the circuit of the driving motor of the belt 2a instead of the clutch 10. Specifications 773,835 and 924,148 are referred to.

Title: Seat suspension for a tractor and the like
IPC: B60N2/52
Filed: 1965-05-14
Abstract: 1,055,372. Resiliently mounted seats. M. A. E. VUICHARD. May 14, 1965 [May 14, 1964], No. 20574/65. Heading A4U. [Also in Division F2] In a seat suspension for a vehicle vertical movement of a seat pan 1 is transmitted by a bar 2 to a piston 3 which is movable in a cylinder 4 secured to the vehicle by brackets 7. Piston 3 divides cylinder 4 into compartments 5, 6. Compartment 5 is connected to a supply conduit 8 of a hydraullic circuit. The pressure in conduit 8 is maintained at a predetermined fixed operating pressure by a check valve 15. Compartment 6 communicates with a closed surge tank 20 and with an auxiliary cylinder 30 through a conduit 21. Cylinder 30 is divided into two compartments 32, 33 by a free piston 31. A body 22 of liquid completely fills compartments 6, 32 and conduit 21 and traps a cushion of air or nitrogen in tank 20. A conduit 34 connects compartment 33 with a return line 10 of the hydraulic circuit. The constant pressure in supply conduit 8 applied to piston 3 is counteracted by pressure of gas cushion 23. When seat 1 is displaced downwardly additional liquid is supplied to compartment 4 at constant pressure. When the vehicle moves over uneven ground gas cushion 23 is alternately compressed and contracted. A rapid rise of seat pan 1 is prevented by the damping effect inherent in the liquid system. A check valve 28 and throttle 27 may be provided to increase the damping effect. In a modification, Fig. 3 (not shown) vertical movements of seat pan 65 are transmitted to an axially movable piston 62 in a cylinder 60 by a lever 63, 64 pivoted at 66 and piston rod 61.
