Patent GB-903097-A (GB)
Title: Pressure operated controller
Inventor: SIMMONDS MILO RIGGS
IPC: B64D17/56
Filed: 1960-09-05
Abstract: 903,097. Toggles. REPLOGLE, E. H. Sept. 5, 1960, No. 30512/60. Class 80 (3). A pressure-operated controller for striking a movable member 15 comprises a toggle device 22 arranged in a cocked energy-storing position and movable to apply an impact force to the member 15 with a snap action, the cocked toggle device 22 being biased against a stop 23, and pressure-sensitive means, e.g. bellows 24 movable to push or pull the toggle device 22 away from the stop 23 to the released position. During its movement from cocked to released position the toggle device 22 releases excess energy over that supplied by the bellows actuation. In the embodiment shown, the toggle device 22 consists of a spring strip seated in notches 28 in each leg 26 of a U-shaped frame 25 and it bears against the stop 23 comprising a tubular sleeve adjustably mounted in a transverse frame member 29 which is adjustable to vary the spacing between the legs and thus the spring's energy-storing capacity. One end 33 of the bellows 24 carries an axially-projecting member 35 slidable in the stop 23, while the other end 34 is adjustably fixed by a stem 36 to the frame cross-bar. Decreasing atmospheric pressure at altitude causes the member 35 to move and engage the cocked spring strip 22 so that it passes centre and snaps into the released position 22a, Fig. 3, thereby pushing the seat lever 15 out of engagement with linkage 16, 17 to open a fluid-supply valve 18. Modifications are shown in which the controller is actuated, after arming, by the increasing atmospheric pressure on descent; and in which the controller acts to release a hook attached, e.g. to a parachute.

Title: Sheet feeding method and apparatus therefor
IPC: B65H3/40
Filed: 1948-11-26
Abstract: 653,225. Feeding sheets. BELLUCHE, F. R. Nov. 26, 1948, No. 30736. [Class 100 (i)] A method of feeding sheets from a stack 7 or a fanned-out bank includes the steps of lifting and forwarding the rear edge portion of the top sheet, by means such as a combing- roller 8, vertically-reciprocating sucker 10, and a forwarding sucker 11, blowing air under the top sheet from a presser foot 9 &c. as the sheet is moved forward, continuing forward movement of the sheet, by means such as a registering gripper 13 or sucker, and simultaneously lifting and forwarding the rear edge of the next sheet. Also, simultaneously, air is blown, from a device such as 12, under the top sheet as the latter is forwarded, and under the next sheet as its rear edge is forwarded to uncover the rear edge of the following sheet. In this method, air is blown for sheet separating and forwarding for a substantial part, e.g. 460 degrees of two cycles of the sheet feeding means, and ensures complete separation of the sheet from the stack. As shown, the roller 8 first buckles the top sheet against the presser foot 9, the sucker 10 lifts the sheet vertically, and the foot 9 moves out and back on to the top of the next sheet during the 180 degrees of the first feed cycle ; then the forwarding sucker 11 comes to the side of the sucker 10, to group the sheet and advance it a short distance, and the roller 8 descends to the next sheet to complete the first feed cycle of 360 degrees. During the first cycle, at 220 degrees, air is discharged from the hollow foot 9 under the first sheet, and continues until the end of the cycle. At the end of the first cycle, air is blown from the nozzle 12 connected to the gripper 13, and continues for 240 degrees in the next cycle, when the sheet enters the bight of feed rollers. The cam and other mechanism, including the grippers 13, may be as described in Specification 546,649.
