Title: Improvements in or relating to valve-operating mechanism for internal combustion engines
IPC: F01L1/22
Filed: 1955-09-07
Abstract: 801,372. Valve gear. EATON MANUFACTURING CO. Sept. 7, 1955 [Sept. 16, 1954], No. 25628/55. Class 7(6). In a clearance adjusting device comprising a screw 32, Fig. 3, and nut 31 biased apart by a torsion spring 38, the screw is rotated step-by-step in one direction by an oscillating member in the form of a cam-operated push rod 30 acting through a one-way clutch. As shown, the push rod 30 operates a valve rocker 22, oscillation being effected by a pin 45 riding in a cam slot 42 in a fixed bracket 44. The clutch is constituted by a surface 37 on the end of the rod 30 frictionally engaging a shoulder on the screw 32 assisted by a contractile spring 48. During the down stroke of the rod 30, the friction between a ball 26 and a seating on the end of the nut 31 prevents rotation of the nut, and rotation of the rod turns the screw 32 into the nut thus shortening the valve-operating linkage and compensating for valve lift loss. When the valve is seated, the friction is insufficient to hold the nut 31, and the spring 38, which was wound up when the screw entered the nut, uncoils and lengthens the linkage to adjust for wear, expansion, &c. The end of the screw 32 enters the rod 30 and is retained by a wire clip. In a modification, Fig. 2 (not shown), the clip is replaced by a spring. In Fig. 4, a push rod 30<SP>11</SP> rotates a member 30<SP>1</SP> step-by-step through a clutch as in Fig. 3. and the friction between a seat 27<SP>1</SP> on the member and a ball 26<SP>1</SP> on the end of a screw 32<SP>1</SP> is utilized to turn the screw and shorten the linkage, a spring 38<SP>1</SP> being meanwhile wound up and subsequently unwinding to lengthen the linkage.

Filed: 1923-10-18
Abstract: 227,529. Peters & Co., Ltd., G. D., Hibberd, r. C., and Cross, J. W. Oct. 18, 1923. Force-transmitting mechanism.-In brakes for railway and like vehicles. means for multiplying the initial movement of the pull or push rod relatively to its subsequent movement, to take up the slack in the brake rigging rapidly, comprises a pair of links 12 pivotally connected, at one end and at an intermediate point nearer to the other end, respectively to the pull or push rod 17 by a pin 16, and to the short arm 3a of the actuating-lever 3 by a pin 11. The links carry a pin 18 at their other end. which is preferably screwed through and welded to the links and engages by means of an antifriction roller 20 a slot 8 formed in an arm 7 extending from a tie-rod 6. With the brakes released, the roller 20 occupies the position shown in Fig. 1, but, the initial upward movement of the lever 3 causes the roller to travel down the cam-shaped surface of the slot so that the links 12 pivot about the pin 11 to increase the travel of the pull rod 17. When the roller has reached the position shown in Fig. 3, any subsequent movement of the lever 3 moves it along the lower part of the slot 8, the surfaces of which are formed by arcs struck from the pivot 4 of the lever, so that the movement of the pins 11, 16 is equalized, and the links 12 serve merely as connecting-rods between them. The pair of links 12 may be replaced by a single link of U-shape. The invention is shown applied to vacuum brake apparatus of the kind described in Specification 18795/10, but is equally applicable either to vacuum brake apparatus actuated by a main rock shaft, in which case the links 12 would be associated with the short crank arm or arms on the rock shaft, or to hand-actuated brake apparatus for railway wagons.

Abstract: 601,859. Lubricating. DARLING & SELLARS, Ltd., DARLING, P., and BETTS, R. Oct. 9, 1945, No. 26271. [Class 12 (iii)] [Also in Group XXVIII] A lubricating pump has its plunger directly operated by a roller carried in the pump casing and reciprocated by the relative transverse movement of the links of a chain, the plunger on its delivery stroke first closing an inlet port and then delivering the oil past a non-return valve to various passageways or conduits leading to the areas required to be lubricated. Thus, oil from a reservoir H carried on a lathe saddle is pumped to the various slideways of the saddle by the engagement of a roller D with the links of a stationary chain A extending along the lathe bed, the roller being guided in an extension F on the pump body B and engaging against an enlarged end G of the plunger C. Oil enters the plunger cylinder from the reservoir H by ports I and when these are closed by the inward movement of the plunger the trapped oil is forced past a non-return ball valve K to a distribution chamber M from which conduits O branch out to the various slideways P of the lathe saddle Q.

Abstract: 1,151,875. Automatic temperature control systems. WAGGON BAU DESSAU VEB. June 14, 1966, No.26432/66. Heading G3R. A system for a temperature controlled van comprises duplicate diesel generator units each supplying a refrigeration compressor or heaters alternatively, in dependence on temperature, arranged in a main and auxiliary mode. Initially both diesel units are run until the desired temperature is reached when the auxiliary unit is stopped leaving the main unit to cope with refrigerating or heating load. If however the load persists for more than a time determined by a heater acting on a semi-conductor such as a thermistor, indicating an inability of the main unit to cope, then the auxiliary unit is started. Similarly if the main unit malfunctions due to say low oil pressure or high oil temperature, the auxiliary unit is started and the main unit is stopped. Switches are incorporated to reverse the functions of the units and to provide manual control. In the arrangement -described a number of non- adjustable thermostats are employed switchable to select the desired temperature.

Title: Improvements in and relating to apparatus for testing spark plugs, ignition and other electric leads
IPC: H02G3/12
Filed: 1945-10-10
Abstract: 607,782. Indicating faults. GILBERT & BARKER MANUFACTURING CO. Oct. 10. 1945, No. 26441. Convention date, Dec. 2, 1944. [Class 37] [Also in Group XXVII] The invention relates to apparatus for testing sparking plugs, ignition and other electric leads comprising a cathode-ray oscilloscope on the screen of which may be shown patterns corresponding to various conditions of the sparking plugs or leads. As shown, a transformer T, having a primary winding 11 connected to a source of alternating current has one of its secondary windings 15 connected to a potential divider comprising resistances R11 to R23 through series resistances R1 to R10. A cathode-ray tube O, having two sets of ray-deflecting plates 37, 38, 39, 40 is associated with the, transformer and potential divider. A secondary 19 of the transformer is connected through a phase altering network N to one plate 39 and the opposite plate 40 is connected to a terminal 54 of the network through an earth connection. Plate 38 is connected to earth and plate 37 to a point between resistances R22, R23. Thus the plates are supplied with alternating current, the phase of that supplied to plates 39, 40 being 90 degrees out of phase with that supplied to the plates 37, 38. The circuit values are chosen so that the voltages on the plates are equal. Transformer secondary windings 16 to 18 supply the cathode-ray tube in a conventional manner. Thus the beam on the cathode-rav tube describes a circle on the screen 36. Leads 34, 35 are connected respectively to resistor R23 and to an arm 23. The arm 23 co-operates with contacts 1 to 10, each connected to a different point of the potential divider. If the leads are connected between the central electrode and earth electrode of a sparking plug and there is leakage across the plug the voltage on the potential divider drops and causes the voltage across resistance R23 to drop. This alters the pattern on the screen to an elipse. If the plug is short-circuited the pattern on the screen becomes a straight line. In this way sparking plugs, ignition leads and other electric leads can be tested. The sparking plugs and ignition leads can be tested while in place on an engine. In the case of a sparking plug, the leads 35 are connected to the frame of the engine and the lead 34 to the plug electrode, the plug lead having been removed. The length of the spark plug gap can be tested by turning the arm 23 to increase the voltage on the plug until the plug sparks the position of the arm giving an indication of the voltage and thus an indication of the length of the plug gap. The discharge of the plug will be shown on the cathode-ray tube screen. The Specification as open to inspection under Sect. 91 states that any other article (apart from ignition leads) susceptible of treatment in a similar manner, may be tested. This subjectmatter does not appear in the Specification as accepted.
