Title: Improvements in or relating to pump and motor combinations
IPC: F04D9/00
Filed: 1949-11-01
Abstract: 701,507. Centrifugal pumps. HAYWARD TYLER & CO., Ltd., and IVANHOFF, A. Jan. 31, 1951 [Nov. 1, 1949], No. 27948/49. Class 110 (1). [Also in Group XXXV] In a motor-driven pump in which the pump and motor are housed in virtually a single casing, the level of the casing in relation to the external system through which the pump circulates liquid is such that, when an air outlet giving egress from the upper end of the casing is opened, any air in the casing will escape and the casing will be filled with liquid from the external system. The motor-driven pump described in Specifications 701,509, 701,510 and 701,511, comprising a motor casing 1 joined to a pump casing 2 by a neck portion 3, circulates water between the water drum 4 and the water tubes 5 of a boiler. Before use, a cock 16 is opened, and water from the boiler fills the casings 1, 2, 3, the air being expelled through an outlet 15 which is situated a distance h below the water level 17. To prevent damage to the motor windings, the water is cooled in a cooler 9 before entering the casing 1, the circulation being maintained by an auxiliary impeller at the top of the motor shaft. If air collects at the top of the casing 1, the circulation stops, and it becomes necessary to repeat the, air-expelling, operation. Warning is given by a thermometer 21a, which may be arranged to actuate an audible device. To prevent the rate of air release from becoming so high that hot water passes directly into the casing 1, the flow is restricted by a fine bore tube 19. A porous metal plug between the cock 16 and the tube 19 prevents the latter from being clogged by foreign matter. Alternatively, an additional cock, separated from the first cock by a length of pipe, may be provided, the two cocks being operated in succession so that air; first enters and is closed off in the length of pipe and is then released therefrom. The pipe may be of oval crosssection to render it expansible. The direction of now through. the coil 9 may be opposite to that shown. The cock 16 may be situated at the highest point of the cooling circuit.
Patent GB-209809-A (GB)
Title: Means for attaching hinged lids to rectangular metal boxes
IPC: B21D51/52
Filed: 1922-10-14
Abstract: 209,809. Ney, A. F. Oct. 14, 1922. Hinges.-Relates to making boxes and consists in a machine for inserting hinge-pins in position in rectangular metal box bodies already provided with hinge "pops," and for curling the hinge " tail " of the box lid in position around the pin, all the operations required being effected in timed sequence by means actuated from a single cam-shaft, the completed boxes with the lids closed being carried away on a travelling belt. The box bodies B are caused to travel along a channelled guide 2, Fig. 1, which shows the machine in plan, past the various operating mechanisms, by an intermittently-moving chain carrier 1 passing over sprockets 106, 107, Fig. 2. Wire to form the hinge pins is drawn from a reel 4, through straightening pins, by grippers 6, 7<a>, which forward it through a guide hole in the fixed part 12 in which it is cut by a cam-operated pivoted knife 13. The pin P thus produced is fed through an inclined hollow guide 17 and engages a guide groove 18 in a clamp 19, Fig. 9, while its forward end p enters the foremost hinge " pop " 29 on the box, Fig. 5, and is held against the inside thereof by a spring-controlled gripper 30, mounted on an arm carried by a reciprocating carrier 21, Fig. 6; the gripper takes inside the box, and has a shoulder 31, Fig. 10, against which the forward end of the pin abuts. After a pause, the carrier 21 is caused to move backwardly, the box chain carrier being meanwhile stationary, so that the shoulder 31 of the gripper pushes the pin backwards towards the rear hinge " pop " of the box, the gripper meanwhile swinging on its pivot and releasing its hold of the pin, the box resuming its advance until a reversal of the movement of the carrier causes a pin 32 on the clamp 19 to engage the pin P within the rear hinge " pop " and the shoulder 31 of the gripper again to contact with the front end of the pin, completing its insertion in the hinge " pops." The box bodies, continuing their advance, arrive at the lid-attaching mechanism, where lids L, fed down a shoot 57, Fig. 17, come to rest in an angular position overlying the boxes, supported on a spring-controlled elevator capable of vertical reciprocation. As the elevator rises the edge 93, Fig. 14, of the hinge " tail " 63 passes between the pin P and the box body, after which a hook 75, Figs. 1, 2, draws the lid back so that it swings into full open position. The box is prevented from rising during its progress towards the subsequent lid-attaching operations, which are performed by a presser-foot 83, Fig. 18, working in co-operation with a reciprocating backing block 187, and effect the bending of the tail 93 to enclose the hinge-pin. The advancing box is next pressed on the side opposite the hinge to correct bulging and ensure the lid closing properly, and later encounters an inclined arm 104 which raises and closes the lid, after which the completed box drops on to, and is carried away by a travelling belt 108.
