Title: Improvements in or relating to vertical self-priming pumps
IPC: F04D9/02
Filed: 1945-01-16
Abstract: 588,939. Self priming pumps. LA BOUR, H. E. Jan. 16, 1945, No. 1346. Convention date, March 8, 1944. [Classes 110 (i) and 122(v)] A vertical self-priming pump of the kind described in Specification 559,086 is modified to improve the priming action and the liquid seal and to facilitate disassembly and replacement. The casing 24, Fig. 1, forming the impeller and liquid-seal chamber is made as a separate piece. Its exterior has two arcuate flanges 30, the pump discharge ports 28a lie above these flanges and the priming entry ports below. The lower wall 36 of the rotary seal box is formed with blades 43 which have a radial limit shorter than that of the blades 42 on the upper wall 33. The sealing sleeve 39 has a recessed surface which lies near to the shoulder 44 on the impeller shaft 38. When the sleeve 39 is forced downwards, in disassembling, by screwing its nut 94 against the undersurface of the motor shaft 60, the recessed surface and shoulder 44 contact and, thereby, stressing the sealing disc 40 is avoided. The priming action is improved by means of air vents 52 from the discharge ports and a liquid inlet 50 at the bottom of the pump chamber and, it may be, a similar liquid inlet in the side wall of the chamber. A ball 79 is located in the discharge pipe between a stop 80 and stops 82, 84. In the position shown, it serves to retard the back-flow from the discharge when the pump stops. Against the stops 82, 84 it leaves a free passage for the pumped liquid. The bearing pillar 8, which is carried by a cover-plate 7 and supports the motor shaft 60, has a sleeve 78 substantially filling the space between the ball-races and thereby reducing the pumping action due to changes of temperature of air enclosed by the sleeve. The impeller shaft is received within the motor shaft, is secured endwise therein by a bolt 93 and is keyed to it at 91. Lubricant is introduced at 64, drains into an annular trough 75 and is withdrawn at 77. A cup-like flange 73 keeps the lower bearing full of oil when the pump is stopped. In a. modified construction, the casing parts 5, 12 and the impeller chamber 24 are made of porcelain. Specification 570,212 and U.S.A. Specifications 1,578,236 and 2,291,478 also are referred to.

Title: Improvements in or relating to fluid actuated device
Inventor: LENCIONI LOUIS JOHN
IPC: B23D23/00
Filed: 1955-01-17
Abstract: 782,439. Shearing. COOK, L. H. Jan. 17, 1955, No. 1347/55. Class 83 (4). [Also in Group XXIX] On the completion of a stroke of an hydraulically actuated plunger of a cable cutter the pressure is prevented from rising by a travel limit valve. A single-acting plunger 3 carrying a blade works in a cylinder 1 supplied by a pump 21. A rod 33 is provided in a bore 28 in the plunger and is urged by a spring 34 into closing engagement with an outlet 31. At the end of a stroke of the plunger a shoulder in the bore engages a collar 41 on the rod which is thereby removed from the outlet. In a modification a manually-operated plunger pump draws liquid from a reservoir through a check valve, and delivers to the cylinder through a port closed by the rod 33 which acts as a non-return valve until the end of the stroke is reached, whereupon the port remains permanently open and no further power can be applied since the liquid merely moves back and forth between the cylinder and the pump with the check valve closed. U.S.A. Specification 2,384,130 is referred to.

An inclined roller conveyer for pallets has means for spacing the pallets so that a second pallet is prevented from running into a first pallet which is being removed from the conveyer. The conveyer comprises rollers 4, 5 connected by a chain 8 driven by a motor (not shown) such that roller 4 turns faster than roller 5. Rollers 3 are freely rotatable. As the front edge of a first pallet 1 reaches the roller 4, the pallet is moved at a higher speed than a second pallet 2 on account of the higher peripheral speed of the roller 4. To more positively ensure that the second pallet 2 does not hit the first pallet 1 before the latter is removed, a claw 19 engagable with the pallet 2 is controlled by the pallet 1 reaching the bottom of the conveyer. In Fig. 2, a toggle lever system 13-16 is connected to the claw 19 and is moved to the position shown by a thrust rod 11 and a tension spring 12. A lever 9 connected to the rod 11 is engagable by the pallets. When the pallet 1 engages the lever 9, the rod 11 is moved to the left and pallet 2 is stopped, Fig. 3. When the pallet 1 is removed the pallet 2 is not released until the pallet 1 is at a predetermined distance from the conveyer, Fig. 2.
