Title: Improvements relating to pump installations
IPC: F04D15/02
Filed: 1926-05-03
Abstract: 261,270. Brown, A. S. May 3, 1926. Regulating or controlling; starting, facilitating. - A servo-motor in a pump installation comes into operation automatically on the failure of the pump, and effects stopping, priming and re-starting of the pump at timed intervals. The centrifugal pump 1 is driven by the electric motor 2 and pumps water from the sump 3 to the high level tank 4. The pump also supplies water through the pipe 7 to the tank 6 for priming purposes. The delivery side of the pump communicates with the space 14 beneath the flexible diaphragm 16 of the regulator shown in Fig. 2. The diaphragm supports a rod 18 which can slide vertically in the framework to which is piloted an arm 20 moving with the rod 18. The outer end of the rod 20 is forked and engages a stud 22 on a sliding rod 23 which carries a weight 24<1> and a contact 24. Another contact 25 is carried by the weighted rod 26 which is provided with a dash-pot 28 to delay its fall. The contacts 24, 25 are in circuit with the master switch M and the actuating solenoid S of the motor switch T. When the pump fails, due for example to ingress of air on the suction side, the pressure in the space 14 drops, the rods 18, 23 fall and break the contacts 24, 25 thereby stopping the motor 2. The rod 23 continues to travel downwards, and the collar 34 permits the bell-crank 36 to touch the contact 38 to complete the circuit of the solenoid U. This operates the lever 43 and actuates valves 10, 11 in order to flood the pump casing and suction pipe 5 from the tank 6, and to allow air to escape from the same parts. By the time the pump is primed the rod 26 which has been dropping slowly, owing to its dash-pot, enables the contact 25 to engage the contact 24 to complete the circuit of the solenoid S to re-start the motor 2. As the pressure rises the diaphragm 16 restores the parts to their normal positions and the circuit of the solenoid U is broken at the contact 38 so that the valves 10, 11 are closed. A pilot switch P is connected in parallel with the master switch M and is opened by the float when the water in the tank 4 reaches a predetermined level. A switch 54, 55 closed by the fall of the rod 26 ensures priming even when the switches P, M are open. Where a pump is driven by a fluid pressure motor the electrical control devices may be replaced by fluid-actuated devices supplied from the tank 4.

Title: Improved toggle lever mechanism
IPC: D06F71/02
Filed: 1929-04-16
Abstract: 330,692. Richardson, J. R. S., and Whitaker, Ltd., R. G. April 16, 1929. Ironing-presses.-Toggle-lever mechanism for operating the ironing-machine is provided with a lost-motion connection whereby the toggle action is delayed until the member to be operated thereby has been independently moved through part of its stroke. As shown, one toggle member 7, rigid with the treadle lever 6, is formed with a transversely slotted end 8, the other toggle member 11, pivoted to the head lever, being furnished wlth a roller 9 which travels in the slot. A roller 13 on the end 8 of the lower toggle engaging a heel 12 on the beam concentric with its fulcrum prevents depression of the treadle until the head 3 has been lowered by hand to an intermediate position enabling the roller to ride off the lower end of the heel. During this phase, the toggle roller 9 travels to the opposite end of the slot 8, the treadle then being depressed to apply pressure by straightening the toggles. The toggle 7 is adjustable by screw-and-nut means to vary the point at which the toggle action begins. To open the press, depression of an auxiliary treadle 17 rocks a lever 15, an adjustable stop 16 thereon breaking the toggle joint by impact with the end 8, the beam 1 then being raised by the usual springs 5, a dashpot 18 acting on the treadle lever 6 to cushion the movement.

Abstract: 844,453. Knitting-machines. LIEBRANDT, K. April 10, 1957 [April 27, 1956], No. 11809/57. Class 74 (2). As a shaft 6 is oscillated by variation in the tension of a warp 1 passing over a tension-bar 3, to a warp-knitting machine, a stop 21, carried by a sleeve 10 secured to the shaft, abuts against one or other of adjustable stops 19, 20, carried by a member 12 freely rotatable on the shaft and, if the swing of stop 21 is sufficient, causes one or other of cams 26, 27 to engage the button 24 or 25 of a switch 22 or 23 controlling the drive to the warp beam. A brake comprising friction discs 14, 15 and a spring 17, tends to retain the member 12 in any position to which it has been carried by a swing of the stop 21, until the member is moved by a subsequent swing of that stop. The switch 22 may energize a motor which, through a cone clutch and worms and worm gears, adjusts a gear 36, controlling in turn an infinitely variable warp beam driving gear 9. The cam 26 may also operate an additional switch for resetting gear 36. The switch 23 stops the rotation of gear 9.
