Title: Improvements in or relating to fluid pumps
IPC: F04F1/06
Filed: 1937-06-22
Abstract: 502,889. Raising liquids by vacuum and by gas pressure. SABIN, A. B. June 22, 1937, No. 17387. Void. Convention date, Sept. 2, 1936. [Class 102 (ii)] Apparatus for forcing liquids, particularly liquids containing solids in suspension, comprises a conical chamber 1, communicating with a chamber 11 having an inlet pipe 27 and a discharge pipe 21 provided with valves 32, 33. Each valve comprises a cylinder, secured by a stud 16 or 23, and having a flattened slotted end, serving as a support for a hose 39. The discharge passage has a downward extension 31, beneath which is a nozzle 94 for admitting compressed air, in order to stir the liquid. A perforated float-guide 7 contains a ball float 67, connected by a chain to a hood 64, carried by parallel links 61, 62, which are pivoted to the valve chamber. The latter is secured to the top of the chamber 1, and has a removable cap 44. A rod 69, pivoted to the link 61, is slotted to engage a pin 76 carried by a lever 74, which is connected by springs 92 to a lever 75. To the latter are pivoted a stem 78 carrying upwardly-seating valves 84, and a parallel stem carrying downwardly seating valves 88. The bore containing the valves 84 is connected by a passage 55 to vacuum, and the bore containing the valves 88 is connected to atmosphere, or to super-atmospheric pressure. In the latter case the air in the pump chamber is vented to atmosphere before the chamber is connected to vacuum. For this purpose the vacuum line 111 contains a diaphragm valve 113, which is exposed to the pressure in the pump chamber through a line 114, so that the valve is held closed until the pressure in the pump chamber falls to atmospheric. Venting is effected by a valve 112, which opens only when the pressure is above atmospheric. A valve 71 on the rod 69 prevents entry of liquid into the valve chamber. The apparatus may supply a tank, the level in which is the same as the low level in the pump chamber.

Title: Improvements in and relating to shears for cutting metal strips
IPC: B23D25/06
Filed: 1943-10-26
Abstract: 567,516. Shearing. LOEWY ENGINEERING CO., Ltd., and HENSCHKER, E. Oct. 26, 1943, No. 17597. [Class 83 (iv)] In flying-shears having a frame 20, for fixed and moving blades 23, 24, rocked by a cam 30, a double-acting pneumatic cylinder 50 has its piston so connected to the frame 20 that it can be used to urge the frame in the direction the work is fed and thereby keep the follower 31 in contact with the cam 30 or to urge it in the opposite direction and keep it still by keeping the follower away from the cam that is mounted on a shaft 12 driven through reducing gearing 17 and an electromagnetic clutch 15 by an electric motor 13 controlled by a regulator 14. The shaft 12 pivots the frame and has cranks 27 which reciprocate the blade 24. The follower 31 is carried by an arm 32 which oscillates two arms 38 through linkwork 34 ... 37. Two links 39 connect the frame 20 to nuts 41 adjustable along the arms 38 by screws 42 rotatable by gearing 43, 44, Fig. 3, 45, 47, 48, Fig. 2, and a hand wheel 49 which may also adjust the motor regulator 14. When the piston 51 keeps the cam 30 and its follower 31 in contact and the rollers 57, driven through variable speed gear from the motor 13, feed the work, the blades 23, 24 act normally to divide it into lengths and any tendency of the shears to travel faster than the work, during cut, merely results in a momentary separation of the cam 30 and its follower 31, but when the piston 51 acts in the reverse direction to keep the frame at rest, the blades can be used to cut out defective lengths of the work. The movement of the frame is limited by stops 55, 56. The clutch 15 may be controlled by means which prevent the blades from cutting the work strip until a desired length has been fed.
