Title: Improvements in or relating to hop picking machines
IPC: A01D46/02
Filed: 1947-09-01
Abstract: 641,731. Endless-chain conveyers. GRAY, C. J., and GUINNESS, SON & CO., Ltd., A. Sept. 1, 1947, Nos. 24143/47 and 22794/48. [Class 78 (i)] [Also in Groups I and II] In a hop-picking machine provided with a conveyer for trailing the hop-bines between co-operating picking combs, the bines are loaded manually on to bars from which they are removed by gripping devices on the conveyer, the arrangement being such that a practically continuous mat of bines is trailed past the combs. The bars 5 are slidably arranged to permit withdrawal transversely from the machine, for loading, and carry pegs 8 over which the bines are laid spring jaws 11 being provided for gripping the bine ends. The conveyer 16 comprises chains 17 interconnected by bars 19 carrying fingers 20, arranged to pass between the bine pegs 8, and co-operating toggles 21. The toggles are pivoted on crank-pins 24 (Fig. 12) which engage recesses in a slidable bar 25. As the fingers 20 approach the bine-pegs 8 a cam-bar 15 on the machine frame engages a roller 26 on the bar 25 and opens simultaneously all the toggles 21 which close on the bines after their reception by the fingers 20. The bines are trailed by the upper run of the conveyer between stationary picking combs 36, and travelling combs 37 carried by a belt 64 and, by the return run of the conveyer, between two sets of travelling combs 37 and 38 on belts 64 and 67. A final set of travelling combs 70 is mounted on links 76, 77, so that it can tilt as the conveyer bars pass. At the end of the lower run of the conveyer, the bars 19 strike the forward arms of a set of pivoted belt crank levers 31 causing the serrated rear portions 32 to rise and press the bines against a stationary abutment 33 on the machine frame. Prongs 34 on a transverse conveyer engage the trailing bine-ends and drag the bines away.

Title: Liquid delivery apparatus adapted for the delivery of motor fuel, petrol and the like
IPC: G01F15/06
Filed: 1936-09-04
Abstract: 474,490. Counting-apparatus. SAUSER AKT.-GES. Sept. 4, 1936, No. 24258. Convention date, Sept. 13, 1935. [Class 106 (i)] In liquid-dispensing apparatus provided with totalizing and trip counters for indicating respectively the total liquid delivered and that at each operation, a setting member is provided which is adjusted beforehand to the quantity of liquid to be delivered, and during delivery this setting member is rotated stepwise backwards into the zero position by the measuring- apparatus whereupon the measuring-apparatus is automatically stopped, and, by rotating the setting member backward beyond the zero position it is made inoperative. The invention is described as applied to the apparatus set forth in Specification 474,489. The setting member comprises a toothed ring 77 rotatably mounted on a graduated bezel 76, and is rotated by a pointer handle 115 until it indicates the desired quantity on the bezel. The ring rotates through gearing 110, 109, 107, 105, a sleeve 102 rigid with a cam 104 and pinion 103, the pinion 103 meshing with a pinion 125a rigid with a wheel 125 which cannot drive but may be driven by a four-toothed wheel 124, Fig. 7. When the liquid is delivered as described in the above-mentioned Specification, the measuring-apparatus drives a shaft 8 coupled at 28 to shaft 29 which through gearing 30, 31 rotates a shaft 32 which drives the trip and total counters 200, 300 through gearing, and through gearing 32a, 118, 120 drives a wheel 121, the left-hand side of which has two teeth only, Fig. 6, and rotates the wheel 124 step by step. The four-toothed end of wheel 124 through gearing 125, 125a, 103, 105, 107, 109, 110 therefore rotates the setting ring 77 backwards step-by-step to the zero position when the projection 128, Fig. 5, on cam 104 rocks an arm 130 rigid with shaft 131, Fig. 3. The arm 133 thereby through arm 135 rocks shaft 91, an arm 93 on which then releases arm 83 which is rocked by a spring 84, and, as described in Specification 474,489, stops the delivery of the liquid. If the setting ring 77 is turned backwards beyond the zero position until the handle 115 meets a stop 117, the sleeve 102 is also rotated backwards until a gap 106, Fig. 5, in the wheel 103 comes opposite the pinion 125a, whereby any further rotation of the measuring device has no effect on the setting ring 77. The arm 130 is also released by the projection of cam 104 and a spring rocks shaft 131 to the position shown to release levers 135 and 93 when the measuring-apparatus may again be restored to the delivery position as described in Specification 474,489.

Abstract: 709,076. Engine stop-gear. C.A.V., Ltd. Oct. 14, 1952 [Oct. 26, 1951]. No. 25062/51. Class 122(4) A safety device for internal combustion engines of the compression-ignition type to which liquid fuel is supplied by a pump controlled by a governor responsive tc pressure variations in the engine air intake manifold comprises a valve adapted to control the communication between the manifold and the governor and to reverse the normal action of the governor to thereby interrupt the fuel supply and stop the engine when reversal of pressure condition occurs in the manifold. The output of an engine fuel pump g is controlled by a rack f actuated by a spring-loaded diaphragm d dividing a governor chamber a into two compartments b and c normally connected to the engine air intake manifold q and the atmosphere respectively Interposed between the manifold and the governor is a valve comprising an axially bored stepped piston k loaded by a spring m and having its larger and smaller diameter portions slidable in coaxial cylinders i and j respectively. The cylinder i is connected at one end to the atmosphere through a passage t and a filter u and at the other end to a venturi throat p in the manifold q by a pipe o and has a port r normally connected via by a pipe s to the compartment c. The cylinder j is normally connected by a port v and a pipe w with the compartment b. During normal running the piston k occupies the position shown in Fig. 1 and the governor operates in the normal manner being connected to the manifold through the bore in the piston k and the port v and to the atmosphere through the port r and the passage t. If accidental reversal of direction of engine rotation occurs with consequent reversal of the pressure condition in the manifold q, the positive pressure acts on the larger end of the piston k and moves it to the right against the action of spring m and causes the governor compartment b to communicate with the atmosphere and the compartment c to communicate with the manifold. In this condition the diaphragm d moves the rack f to a position in which the fuel supply is interrupted and the engine stops.
