Title: Improvements in or relating to devices for storing liquids and feeding them at a constant level
IPC: F16N19/00
Filed: 1934-09-10
Abstract: 421,170. Regulating liquid-levels. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and BINNEY, E. A., Shirley, Ilkley, Yorkshire. Sept. 10, 1934, No. 25958. Addition to 397,857. [Class 123 (i)] The arrangement described in the parent Specification is modified to avoid the use of a 3-way valve. A duct connects the filling chamber to the bottom of the intermediate chamber, and passes through and has a valved opening into the lowest or constant level chamber. In the application to a bearing lubricator, the bearing cap 10 includes an opentopped wick chamber 10<a> which is extended to form a constant level oil chamber 10<c> having a part 10<e> provided with a level indicator. This comprises an adjustable washer 11 just below the oil level XX so that a fall in this level results in the disappearance of the oil below the washer. The intermediate chamber 13 carries an upper filling chamber 15, and a U-shaped duct 17, 17<a>, with a valved opening 18 into the chamber 10<c> connects the chamber 15 with the bottom of the chamber 13. A valve 20 is carried by a rod 19 and is held closed by a spring 22 when the removal of the cap 16 permits the rod 19 to rise. The valve may be held open independently by a catch 24. The two chambers 13, 10<c> also communicate by a tube 27 having a levelcontrolling vent 26 as described in Specification 384,858. The level may be adjusted by providing the tube 27 with a bellows or like extensible part as described in Specification 413,554 or by varying the thickness of the packing 25 to raise the chamber 13 with its attached parts. The arrangement of the valve rod 19 and cap 16 ensures that the cap cannot be replaced when the valve is closed. The bearing may be flooded by pouring oil into the chamber 15 when the valve is latched open. Alternatively, this operation may be prevented by modifying the valve so that when the opening 18 is uncovered, some part of the tube 17 is closed.

Title: Improvements in or relating to agricultural implements
IPC: A01D78/00
Filed: 1959-08-05
Abstract: 914,097. Agricultural implements; hay-making machines. VAN DER LELY N. V., C. Aug. 5, 1959 [Sept. 4, 1958], No. 26755/59. Classes 6(1) and 6(3). In an agricultural implement wherein the tools are raised for transport or are movable between two alternative working positions, the movement of the tools is effected by mechanism including an energy-accumulator which is supplied with energy from a groundwheel during normal operation and releases it for moving the tools when actuated by an operator. The arrangement is shown applied to a rake-wheel type of side-delivery rake, the main frame 1 of which carries rake wheels 8 and is supported by wheels 12 which are relatively adjustable vertically to raise and lower the rake-wheels. The frame 1 is connected to a tubular standard 25 by pivoted parallel links 14A, 14B and by a lifting mechanism 34 coupled to the frame through a link 38. The lifting mechanism is carried by a fork, at the top of the standard 25, and comprises a half-revolution clutch which tensions a spring 46 and is supplied with increments of movement through a crank 56 and pitman 55. The clutch, Figs. 5-8 (not shown), includes means for arresting rotation just past top-dead-centre, when the spring is fully tensioned and means for coupling the spring to the lifting link 38, the latter means being actuable by a cable 77A which passes through the tubular frame 1. In Figs. 18 and 20, the energy-accumulator is hydro-pneumatic and comprises a gas-cushion 125 in a cylinder 124 carried by the standard 25. The wheel 12 carries a pump 126 and hydraulicfluid reservoir 127 from which pipes 128, 128a lead through a slide-valve 132 and through a manually actuable rotary valve 143 to the cylinder 124 and to a lifting cylinder 123 fixed to the main frame 1 and operable to lift the link 14A through the piston-rod 121 and pivoted lever 120. Increments of pressure are supplied by the pump 126 to the cylinder 124 until the pressure therein is sufficient to operate on a piston 130 to close the slide valve 133. Rotation of the rotary valve 143 to inter-connect the cylinders 124 and 123 is effected by a ratchet 146 and cable 154. The tools are then lifted by the ram 123; when they fall again by further rotation of the valve 143, the expelled fluid passes back to the reservoir 127 through the pipe 128A. In Fig. 21, the energy-accumulator is a rotating flywheel 161 which is kept in continuous rotation by gearing 174, 175 and 171, 172 through a slip-clutch 169. A threearmed trip-lever 177, 178, 179 carries a roller 180 which bears on an extension 181 of a toothed quadrant 163 whereby the latter can be engaged with a crown-wheel 162 on the flywheel on the pulling of a cable 184. In a modification, Fig. 22 (not shown), the arrangement includes means for swinging the rake-wheels between side-delivery and tedding positions. Specification 914,096 is referred to.
