Abstract: 743,417. Rolling-mandrel carriages. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd. Feb. 12, 1954 [Feb. 27, 1953], No. 5608/53. Class 83 (4). In a pilger rolling mill the shock transmitted to the carriage 11 by the cushioning means at the end of the return stroke, is taken up by hydraulic piston and cylinder apparatus 17, 18 from which hydraulic fluid is released in a predetermined quantity per operation so that the feed rate is precisely controlled. The cylinders 17 which are also used for stripping the work from the mandrel 33. are mounted on the base 10 and the pistons 18 are connected to a cross-head 19 on the carriage 11. The release of fluid from the cylinders 17 during the forward feeding steps of carriage under actuation by a hydraulic cylinder 13 is controlled by a pair of opposed cylinders 42, 43 which are alternately connected after each operation by an automatically actuated change-over valve 47, a stop valve 48 providing a restricted orifice for the flow. The common piston 52 of the cylinders 42, 43 is limited in its movement between stops 54, 55 and adjustment is provided by packing 61. The cylinders 42, 43 are mounted on slides 59, 60, and are yieldingly located against stops 57 by springs 58 or equivalent hydraulic or pneumatic cylinders so that on the transmission of the shock resulting from the arrest of the work by the cushioning means additional fluid passing to the cylinders 42, 43 in compressing the springs 58 is restored to the cylinders 17 to maintain the constant rate of feed. In stripping the finished work from the mandrel 33 high pressure fluid is supplied to the cylinder 17 through a pipe 63 and valve 49.

Title: Improvements in or relating to reciprocating pumps, particularly windmill driven vertical lift pumps
IPC: F04B17/02
Filed: 1944-03-29
Abstract: 572,096. Windmill &c. pumps. CROFTON, W. B. March 29, 1944, No. 5802. [Class 102 (i)] In a windmill-driven vertical lift or like reciprocating pump, a combined trip and inertiamass mechanism is provided to determine automatically at the end of each idle stroke of the windmill rod or pitman, whether a power stroke will be transmitted to the pump rod or plunger equal to or different from the constant stroke of the pitman, according to the power available. In the form shown, the pump rod 10 passes through a bracket 8 resting on the top of the rising main 8 and carries a cross-head 11 with guide rods 13 slidable in sleeves 14 on the pitman 4. The cross-head 11 is pivotally connected, preferably adjustably, by links 15, 15a to levers 1, 1a pivoted on the pitman and pivotally connected by links 6, 6a to the bracket 8. The pitman 4 also carries a ramp 17 engaged by a roller 22 on the arm 21 of a pendulum 18 which is carried by a fixed pivot 19 and which is connected to a pusher-bar 23. The latter carries a replaceable sleeve 25a slidable through an apertured bracket 25 on a lever 26 carried by a fixed pivot 27. A rod 31 supported on a compression spring 26a projects upwardly from the lever 26 and engages a latch 34 pivoted on a bracket 32 on the pitman 4. The latter also carries a bracket 35 on which is pivoted a tie-rod 37 with a hole 38 opposite a pin 39 on a cross-piece 40 secured to the guide rods 13, whilst the tie-rod 37 has a lateral extension 41 under the downward .constraint of a spring 42. With normal power available, the roller 22 rides up and down ramp 17, the pin 39 and hole 38 are disengaged, and the pump rod 10 is reciprocated by the lever system at half the stroke of the pitman 4. With an excessive power, the ramp 17 throws the pendulum into the position 18b, the pusher-bar 23 forces the rod 31 to the position 31a where it is held by the latch 34 which release the extension 41, and the spring 42 causes the pin 39 to enter the hole 38. The pump rod 10 is therefore reciprocated in unison with the pitman 4. The lever system may be replaced by a rack-and-pinion or chain-andpulley drive, and the pendulum by an inertia wheel.

Filed: 1935-02-26
Abstract: 432,700. Endless - chain conveyers. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London, and MACKLEY, A. H., 15, Waterloo Road, Bedford. Feb. 26, 1935, No. 6127. [Class 78 (i)] A device for transferring articles 4, Fig. 1, from a continuously moving conveyer or elevator 1 to another continuously moving conveyer 2 driven by an electric motor 15, comprises a carrier 5, which is normally at rest in the position shown and which is carried by a pair of parallel links 8, 9 pivoted thereto at 6, 7. The links are rotated in an anticlockwise direction in unison, when an article is to be transferred, by a belt 14 passing round pulleys 12, 13, the pulley 13 being driven through belts 16, 16<a> and an intermediate pulley 17 from the motor 15. An electricallycontrolled clutch 18 is interposed between the motor 15 and the driving pulley 19 for the belt 16. When the article 4 reaches the position shown, the clutch is operated and the carrier 5 is moved in a circular path, without changing its angular position, to lift the article 4 off its support 3 on the elevator 1 and deposit it on the conveyor 2. The carrier 5 is composed of a number of parallel fingers which interleave with prongs on the support 3 and with a number of parallel belts which make up the conveyer 2. The clutch 18 is disengaged, when the carrier returns to its initial position, by the carrier or by the article which has then been carried some distance by the conveyer 2. The article 4 on the elevator 1 momentarily closes a switch 21, Fig. 9, to energize a contactor 23 and close maintaining contacts 30. The circuit for the clutch 18 and a brake coil 20 is thus made, the clutch being engaged and the brake held in the off position. The carrier in its initial position or the article on the conveyer 2 opens a switch 34 to break the circuit of the contactor 23 so that the clutch 18 is disengaged and the brake put on. Photoelectric devices may be employed, the arrangement being such that interruption of beams of light by the article on the elevator 1 and conveyer 2 effects closure of relays corresponding to the switches 21, 34.
