IPC: B60T11/32
Filed: 1973-06-29
Abstract: 1431914 Fluid pressure brakcs; valves ROBERT BOSCH GmbH 29 June 1973 [30 June 1972] 31014/73 Headings F2F and F2V A multicircuit protection valve assembly 1 for an air brake system having circuits I, II, III and IV comprises overflow valves 13, 14, 17, 18 each supplying a given circuit and having a closure member 7, 7<SP>1</SP>, 22 or 22<SP>1</SP> urged against a valve seat 11, 11<SP>1</SP>, 20 or 201 by a spring 10, 10<SP>1</SP>, 25 or 25<SP>1</SP> and away from the seat to allow passage of air when a predetermined overflow pressure is attained, a throttle 5, 5<SP>1</SP>, 30 or 301 upstream of each valve, throttles 30, 30<SP>1</SP> of the valves 17, 18 being formed by extensions 31, 31<SP>1</SP> of valve closure members 22, 22<SP>1</SP> respectively and entering bores 26, 26<SP>1</SP> the extensions being so shaped that throttles 30, 31<SP>1</SP> have a larger flow-through cross-section when the overflow valves 17, 18 are open than when they are closed. As shown, pressure air passes from a pump 51 via a pressure regulator 52, defrosting pump 53 and line 3 to a central inlet of the valve assembly. With all circuits I, II, III, IV functioning pressure air passes via throttles 5, 5<SP>1</SP>, seats 11, 111 and outlets 12, 12<SP>1</SP> to circuits I, II when the overflow pressure is sufficient. Pressure air also passes via check valves 15, 15<SP>1</SP> and central passage 16 to overflow valves 17, 18. The throttles 30, 30<SP>1</SP> are formed between the bores 26, 26<SP>1</SP> and extensions 31, 311 and air passes therethrough into circuits III, IV via seats 20, 20<SP>1</SP> and outlets 29, 29<SP>1</SP> when the overflow pressure is sufficient. If pressure in any of the circuits fails the overflow valve associated with that circuit closes under the bias of the respective spring. In the embodiment shown extensions 31, 31<SP>1</SP> are coupled to valve pistons 22, 22<SP>1</SP> on which valve closure members 23, 23<SP>1</SP> are formed, by a universal coupling comprising grooves 35, 351 and 36, 361 respectively formed in extensions 31, 31<SP>1</SP> and members 23, 23<SP>1</SP> and spring rings 34, 34<SP>1</SP> located therein. Circuits I, II represent the service braking lines of a trailer to the front and rear brake cylinders 58, 59 of which is fed pressure from the valves 13, 14 via accumulators 55, 56 and a manually operated valve 57. Air in circuit III is supplied to spring loaded brake cylinder 63, and to coupling heads 67, 68 via a three circuit 2 line trailer brake valve 65 by way of hand brake valve 61 and relay valve 62, air in circuits II and III also being supplied to valve 65. Circuit IV supplies pressure air to a second dary load such as a tipping device or pneumatic shock absorbing device.

Abstract: 720,247. Hay-rakes. MANDRUPS MASKINFABRIK AKTIESELSKAB, A. Dec. 9, 1952. [Dec. 21,1951] No. 31166/52. Class 6 (3). A tractor-mounted hay-rake comprises a transverse rake-beam 2a, 2b to which the curved tines 1 are secured, the rake being mounted on the tractor by triple-links 3, 14 which cross one another and by a chain 33 which extends parallel to the central link 14 to support the rake when the lifting-links 3 are lowered by the tractor lift-arms 11. The central link 14 is bifurcated and the two limbs are pivoted at 13 to spaced brackets12a secured to the rake-beam. Extensions 30 of the link-limbs 14 are connected by arms 31, 32 to brackets 16 hooked on the rake-beam and carrying clearing-rods 17 extending between the tines. As the rake is raised bodily the rods 17 are moved downwardly to clear the tines. Also mounted on the rake-beam are end-loops 37 carrying ground-engaging shoes 38, the loops being resiliently deformed by contact with the ground. In use, the rake is supported by the end-loops 38 and chain 33, but on lifting the arms 11, the chain becomes slack and the loops resume their undeformed shape and the rake is supported by the links 3, 14.

Abstract: 332,146. Dawson, J. Oct. 22, 1928, [Convention date]. Milling-machines.-A continuous cam groove 27 , especially one having a number of symmetric. ally disposed loops, is cut in a plate 22 by a rotary cutter 21 mounted on a bar 19 which is reciprocated diametrically of a revolvillgwheel 11, on which the plate is held by chuck jaws 23 or other means.

Abstract: 319,310. Stanley Automatic Products, Inc., (Assignees of Stanley, E. C., and O'Brien, J. J.). Sept. 20, 1928, [Convention date]. Force-freed lubricating. - A lubricating system for one or more machines comprises a closed oil-tank 11 from which lead one or more main discharge pipes 16 having branches leading to the various bearings, the main pipes being clear and unobstructed while the branch pipes contain a fibrous conducting medium for regulating the flow therethrough, and the discharge from the tank is effected by the generation of pressure therein by controllable means. The conducting medium consists of tufts of fibrous material secured in the strands of a twisted wire cable. The flow through the main line may be controlled by a valve which is controlled by the control mechanism of the machine, so as to be opened and closed when the machine is started and stopped respectively. As shown in Fig. 8, where the main line 16 is supplied two machines through pipes 53 and branches 65, one pipe 53 is controlled by a valve 54 operated by a solenoid connection in circuit with the machine motor, while the other pipe 53 is controlled by a valve 55 interconnected with the belt stripper 60. Pressure may be generated in the tank by a hand pump, by admitting compressed air or steam under the control of a valve, or by heating the tank by means of a steam coil 43, Fig. 4, controlled by a valve 44 or by means of an electric heater controlled by a switch, the valves or switch being controlled by the control mechanism of the machine so that pressure is maintained only when the machine is operating. Where the tank is heated to create pressure, the formation of a partial vacuum on cooling is prevented by connecting a short pipe 48, Fig. 4, leading to a bearing near the tank, to the pipe 16 between a check valve 47 and the tank. When the pressure disappears on cooling, the valve 47 closes, and, when a partial vacuum, begins to form, oil is sucked back through the pipe 48 until air enters therethrough and the vacuum is broken.
