IPC: B23Q5/26
Filed: 1958-07-31
Abstract: 926,660. Drilling. BALDWIN INSTRUMENT CO. Ltd., and C. H. HAY. Oct. 14, 1959 [July 3, 1958], No. 24674/58. Class 83 (3). A machine tool comprises a linearly movable cam 42 moved with the tool carrier by a fluidpressure operated piston-and-cylinder assembly 14, 15 to control the inlet to, or outlet from, the cylinder. A chuck 11 is rotated by a vane-type motor in a base 10 driving through change-speed gearing in a casing 12. A member 24 moves a valve 20 to supply air to feed the chuck 11 or releases the valve so that it is moved by a spring 23 to return the chuck, the supply to each end of the cylinder beingthrough screw.adjusted needle valves. The exhaust from each end of the cylinder takes place through valves 33, 34, Fig. 4, adjustable by screws 69, 70. Each valve has an exhaust inlet 35, Fig. 9, and a tapered plunger 37 moved against a spring 38 by the cam plate 42 acting directly on a follower 62 or through a plunger 64, a lever 65 and a plunger 66. The cam plate 42 is supported on a slideway 45 attached to a flange 17 moved with the tool. A pin 47 on the cam plate slides in a slot in a plate 49 pressed by springs 50 to keep an adjustable abutment 53 in contact with a trigger valve 55. When the pin 47 reaches the end of the slot it pulls the abutment 53 away from the valve. The valve releases the pressure behind the member 24 allowing the spring 23 to reverse the valve 20 and return the tool. As the drill returns, the abutment 53 closes the valve 55 and pressure again builds up behind the member 24 at a rate controlled by a further needle-valve. The piston 15 may be returned by a spring as in Specification 868,816. It is stated in the Provisional Specification that the tool may be a drill.

Abstract: 484,905. Refrigerating. BRANDLI, E. H. Sept. 11, 1936, No. 24826. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 12, 1937.] [Class 29] Absorption machines.-In a continuouslyacting machine of the inert gas type, the strong liquor return pipe 37 from the absorber discharges into two pipes, one of which 40 extends outside the generator 38 to a jet-pump in the upper part of the generator and is heated by an electric coil 42, while the other 39 extends through the generator to the mixing-chamber 41 of the pump. The mixed vapour and liquid issuing from the pump separate so that the vapour flows through the sealing tank 26<1> to the condenser 26 from whence the condensate passes through a second sealing tank 28 to the evaporator. The weak liquor returns from the generator to the absorber, which is provided with superposed perforate trays mounted on a perforate inert gas outlet pipe, through a finned pipe 36. The sealing tanks prevent inert gas from passing into the generator when the pressure in the evaporator exceeds that in the condenser, e.g. when the machine is inoperative. The Specification as open to inspection under Sect. 91 comprises also a machine consisting of electrically-heated vertical generator tube discharging into a superposed separator tank from which the vapour passes to a condenser connected to the lower end of a relatively long condensate reservoir, the upper end of which is connected by an overflow pipe to an evaporator provided with distributing baffles and connected to an absorber supplied with weak liquor from the separator tank.

Abstract: 432,839. Governors for fuel-injection pumps. SCHNURLE, A., 91, Moltkestrasse, Bad Cannstatt, Germany. Sept. 3, 1934, Nos. 25374 and 25375. Convention dates, Sept. 1, 1933 and Jan. 9, 1934. [Class 57] The governor for the fuel-injection pump of internal-combustion engines comprises two speed responsive devices, one operating as an ordinary speed governor and the other adjusting according to the speed the maximum fuel supply. The fuel injection pump a is controlled in the ordinary way by a rod b which can be set by hand lever c and has the usual over-riding centrifugal governor control d. The rod is continued to abut against a cam surface e which is adjusted across the end thereof by means of a pivoted lever f under the control of a second centrifugal governor g. In place of a mechanical speed governor, the cam member e may be moved by a piston under the influence of a hydraulic pressure which is a measure of speed. For this purpose the ordinary lubricating oil pump driven by the engine may be used as the pressure supply. In a modification a single governor may act through two separate connections as by supporting the main governor control sleeve k on a rod which is stepped and carries a washer n with springs l, q on either side. Under ordinary control the sleeve moves against the spring q when the washer n abuts on the shoulder o of the rod p. Additional control is then afforded bv the capacity of the washer n to slide endwise against the spring l. In a further modification the duplicate spring arrangement is carried by radial arms upon which the centrifugal weights i are mounted and from pins z thereon elbow levers w communicate the control to the sleeve k. In this construction the pivoting axis of the levers w are also mounted on radial pins on centrifugal weights x under the influence of spring control.
