Title: Improvements in or relating to apparatus for use in the firing of torpedoes
IPC: F41F3/08
Filed: 1918-11-21
Abstract: 182,493. Burrows, H. B. Nov. 21, 1918. Ordnance breech mechanism.-A device for firing the cartridges producing the gases by means of which torpedoes are launched especially from motor boats, comprises (1) an outer cylindrical casing A with a perforated cartridge chamber B at one end and a side slot C for the insertion and ejection of the cartridges, (2) an inner cylindrical casing G slidable in the outer casing and' locked thereto by an annular nut H with interrupted screw-threads engaging corresponding threads in the rear end of the outer casing, (3) a spring striker J within the inner casing, and (4) means for cocking and releasing the striker. These latter means may comprise two fingers F pivoted at F<1> to a pair of links U and projecting through slots in the outer and inner casings to engage with a lug J<3> on the striker head J<1>, so that when the links U are pulled back by a Bowden wire W through a spring-controlled rod U<2> secured by a cross-piece U' to the links U, the fingers F first cock the striker and then ride on an incline E<3> at the end of their guiding slots, thereby suddenly releasing the lug J<3> on the striker. When the pull on the Bowden wire is removed, the spring V returns the fingers F to the original position, and the pivot pin F<1> at the same time strikes the tail of a pivoted catch T' which pulls the striker back to half-cock and allows the fingers F to re-engage in front of the lug J<3>. These fingers are spring-controlled in one direction to permit them to ride over the lug J<3> on the return stroke. The cartridge head is engaged by a segmented groove G<3> and by a pair of spring claws in the head of the inner casing G. After fire or missfire the annular nut H is turned through 45', and the inner casing G is pulled back until a shoulder G<5> thereon comes against a spring stop A<4> on the outer casing. Towards the end of the movement of the inner casing the end of a groove G<8> therein strikes a projection O<2> on a lever 0 which deflects another lever P against a spring Q and thereby, in conjunction with a spring D, ejects the cartridge R; a fresh cartridge can be inserted. During the unloading and loading, the striker is held at safe by the engagement of a face cam H' on the annular nut H with a corresponding cam M on the end of the striker, these parts being prevented from accidental disengagement by a locking spring catch N on one of the handles H<1> of the nut H. The spring stop A<4> may be pulled out when it is desired to withdraw the inner casing completely from th.e. outer casing. In a modification, the cocking of the spring-striker is performed by a pull on a handle J<5> on its outer end, and its release is performed by a separate pull on a Bowden wire connected to a trigger carried by a pivoted arm.

Title: Improvements in or relating to disc brakes for road and other vehicles
Inventor: KINCHIN JOSEPH WARWICK
IPC: F16D65/18
Filed: 1951-08-21
Abstract: 703,784. Disc brakes. GIRLING, Ltd. Aug. 21, 1952 [Aug. 21, 1951; Jan. 2, 1952], Nos. 19657/51 and 130/52. Class 103(1) In a vehicle disc brake of the type described in Specification 688,382 wherein friction pads 11 on both sides of the disc 10 are applied simultaneously by hydraulic pressure from a single common master cylinder or other actuator 18, a suitable restriction 20 is inserted in the pipe 17 leading directly from the master cylinder, the restriction having the effect of permitting free passage of fluid between the cylinders but of throttling back flow from the actuator cylinder to the master cylinders. The restriction 20 may in practice take the form of a non-return valve assembly providing a greater resistance to flow in one direction than the other. In the valve assembly shown in Fig. 2, the pipe line to the two actuators is connected at 31 and that to the master cylinder at 32. Pressure from the master cylinder thus initially acts on one face of a piston 34 and moves it to the left together with a valve sleeve 37 thus forcing liquid to the left thereof out through connection 31 to the actuator cylinders. Later, after there has been a build up of pressure behind the sleeve 37 sufficient to compress spring 39, the sleeve 37 is unseated from piston 34 and liquid may flow directly in accordance with the force applied to the pedal. On release of the brakes the return of liquid is limited by the possible rearward movement of the piston 34. If, however, there is a build up of pressure in the actuator cylinders to between 100 and 1000 lbs. per square inch due to temperature rise during a prolonged period of braking or other causes, this pressure may be relieved by raising a valve 42 against a strong spring 44. In one alternative assembly shown diagrammatically in Fig. 3, pressure from the master cylinder is applied to the smaller end of a stepped piston 52, liquid from the larger left hand end being forced through the line 53 to the brake cylinders. When the pressure reaches a certain value it may lift non-return valve 56 and act in the annular recess 61 of the piston to neutralize the differential action. Further application at higher supply pressure takes place past the non-return valve 55 through piston 52. When a negative pressure is left in the pipe leading to the master cylinders, liquid can flow from a reservoir past non- return valves 60 and 58. Other valve assemblies are also described. The invention is particularly applicable to disc brakes having pads in light rubbing contact with the disc as described in Specification 519,787.
