IPC: B64C25/22
Filed: 1945-12-13
Abstract: 620,037. Manually-actuated valves. JENNINGS, H. W. K. (Electrol, Inc.). Dec. 13, 1945, No. 33811. [Class 135] [Also in Group XXXIII] A control unit for hydraulic double-acting jacks comprises a lever actuating a plunger 19, Fig. 5, having cam surfaces which co-operate with a series of valves 27, 27a, 28, 28a, so that when the plunger is moved longitudinally into one position by its operating lever, two valves are opened by the cam surfaces to connect pressure and exhaust to opposite ends of the jack, when the plunger is moved into its other longitudinal position, the previously mentioned valves are closed and the other two are opened to reverse the flow to the jack, and when the plunger is rotated by a further lever, the pressure inlet is disconnected from the jack and both sides of the latter are connected to exhaust. Pressure liquid and exhaust are connected to chambers 30, 29, respectively, and the two ends of the jack are connected to ports 27b, 28b. When the plunger is in its upper position, valves 27, 28a are opened and the other two are closed, and the connections are reversed when the plunger is lowered. As applied to the control of the wing flaps and the landing gear on an aeroplane, two separate sets of control valves, each with its associated plunger, are arranged side by side in a single casing 5, Fig. 2, and the actuating levers 12, which have a pin-and-slot connection 21 with the plungers 19, project from the front panel of the casing. The levers 12 are interconnected by a tooth clutch 49 so that, normally, the two levers act together, but when the wing flap lever is in its lower position, a pin-and-cam slot arrangement causes the clutch to disengage and the landing gear lever can be actuated independently. At other times, the clutch can be positively disengaged by pressing sideways on an arm 56 carried in a slot in the wing flap actuating lever. There is a lever and slot connection between the landing gear lever and an emergency pull rod 14 whereby, when the latter is pulled out, an intermediate lever carried thereby rotates the appropriate plunger 19 and the cam surfaces thereon open both exhaust valves and allow the inlet valves to close. A separate lever, not shown, frees the lock usually provided on the landing gear lever when in its " lowered " position.

Abstract: Adhesive is applied to one or both sides of the edges of shoe parts and the like, consisting of one or more layers, with a separating inlay if required, from a container connected to a gear pump employing a distributer from which the adhesive passes through pipes to bodies <PICT:0898396/III/1> <PICT:0898396/III/2> <PICT:0898396/III/3> formed with slots located adjacent to superimposed pairs of feed rollers, from which slots the adhesive is applied to the material in a predetermined width and with a controllable thickness of layer.  As shown, a table 3 supports a container 7 for adhesive, a clutch 4 and a gear 5 for driving a gear pump 70, the drive also being transmitted by flexible shafts 10 (Fig. 3) to four feeding rollers 13; of these the upper one is journalled in an upper body 17, the two central ones in a central body 18, fixed to the table 3, and the lowermost in a lower body 19.  The upper and lower bodies are slidably mounted on the body 18, and can be simultaneously lowered and raised, respectively, by depressing a pedal, not shown, connected to a rod 92.  The rod 92 is pivoted to one arm of a three-armed lever 64, another arm of which is connected by adjustable resilient links to levers 52, 53 for effecting the movements of the bodies 17 and 19, while the third arm is connected by a link 68 to the clutch 4.  Associated with the three upper feeding rollers are slots 29 for applying adhesive, which is supplied by the pump 70 through pipes 85, 87 and 89, the total flow being controlled by a valve 81 and the supply to the individual slots 29 by valves 84, 86 and 88.  A spring-pressed dog 33 is associated with the lowermost feeding roller.  In operation, the upper and lining members of a shoe are separated by inserting an inlay between them, and their edges are passed between the rollers 13 and beneath the slots 29. Depression of the pedal causes the outer rollers to approach the inner ones and grip the edges; at the same time the drive to the rollers and to the gear pump is engaged, so that the edges are fed forward and then coated with adhesive on one or both sides.
