Title: Impact tools
IPC: B25D9/08
Filed: 1971-01-11
Abstract: 1340784 Percussive tool A J SMITH 11 Jan 1971 [2 July 1970] 1289/71 Heading B4C An impact tool comprises a housing 10 including an elongate bore 24 in which an impact head 30 having an impact face 34 is reciprocable between an impact position, as shown in Fig. 2, wherein the face 34 lies outside the housing, and a retracted position wherein the face 34 is retracted into the bore. Valve means are also provided for controlling the flow of a pressure fluid through the tool and are so arranged that when the impact face 34 is displaced by contact with a workpiece the tool automatically carries out a working stroke the head 30 engaging the valve means during movement to the retracted position, and the valve means and the head being driven together under fluid pressure toward the impact position. The tool described includes an inlet chamber 20 communicating with a source of compressed air, and a shuttle valve 40 reciprocable axially of the bore 24 to block or permit communication between the chamber 20 and the bore 24, and to block or permit communication between an exhaust chamber 64 and an exhaust passage 65 which leads to the atmosphere. Within the valve 40 is a pilot valve 72 which includes a head 74 and a stem 76 connected to the impact head 30. The head 74 includes a pressure face 75 defining one wall of a chamber to which pressure fluid may be admitted via a passage 78 in the valve 40 when the pilot valve is in one position, and from which fluid may be exhausted via a flat 106 on a stem 86 connected to the pilot valve when the latter is in another position. Apertures 84 in the stem 86 and 94 in the valve stem 76 provide an exhaust route for the pressure fluid. To operate the tool, which is originally in the Fig. 2 position, the head 30 is contacted with a workpiece and thus moved upwardly. The pilot valve head 74 is thus disconnected from the lower one of a pair of O-rings 80 so that pressure fluid is permitted to flow via the passage 78 into the chamber below the pressure face 75. This urges the pilot valve and impact head upwardly rapidly until the head 30 strikes the shuttle valve 40 and thus forces it upwardly to the position shown in Fig. 5. This seals the exhaust chamber 64 and opens communication between the chamber 20 and bore 24, Pressure fluid thus enters the bore 24 to urge the head 30 downwardly on a working stroke. At the same time other fluid passes via passages 84 and 94 to the chamber 64 and acts on the annular surfaces of valve head 74 so augmenting the power of the working stroke. Back pressure against the working stroke is released when the flat 106 of stem 86 passes below an O-ring 100. The working stroke finishes when the valve head 74 urges a resilient bumper 107 against a surface 108 of the valve 40 and the latter is thus urged to its original position. This allows the pressure fluid in chamber 64 to pass to atmosphere. If the tool is kept in contact with the workpiece, the cycle is repeated, otherwise movement of the head 30 stops. The head 30 may be of metal or synthetic resin.

Title: Improvements in or relating to fluid flow control valves
IPC: F16N29/00
Filed: 1940-01-22
Abstract: 579,152. Valves. SCOTT, E., and BRITISH POWER BOAT CO., Ltd. Jan. 22, 1940, No. 1335. [Class 135] [Also in Group XXXVII] A lubricating system for an internal-combustion engine is so associated with the oil supply valve that the ignition system is rendered inoperative by an electric switch operated by the closing of the valve. As shown in Fig. 1 in connection with an engine of the dry sump type having a pump 32 for supplying oil under pressure to the bearings and a pump 33 for returning oil from the crank-case to an oil tank 34, a safety oil cock 35 is inserted in the suction pump line from the tank to the pump 32. The cock 35 in this case is adapted to short-circuit the magnets to earth when the switch it operates is closed, and thus render the system inoperative. One form of cock is shown in Fig. 3 and comprises a frusto-conical valve 16 connected by abutments 18, 19 to a spindle 17 having an insulated section 40 and a metal end 39 and by means of which the valve can be withdrawn into a cylindrical bore formed in an extension 10 of the valve casing. The valve can be held in open or closed position by the engagement of a finger 21 on the abutment 18 with annular grooves 12, 13 in the valve casing, and a horizontal groove permits movement from one position to another. When the valve is in the open position, the metal end 39 closes a circuit between insulated contacts 41, 42, and thus causes the ignition circuit to become operative. In an alternative arrangement, the switch may be operated by rotary movement of the finger 21 in the groove 12, and this ensures locking of the valve in open position before the ignition circuit is operative. The spindle 17 passes through glands 22 and is operated by a handle 49. A spring 20 presses the valve on its seat in the closed position.
