Title: Bolt-action firearms
IPC: F41A3/22
Filed: 1969-06-26
Abstract: 1,268,964. Bolt action firearm. HOWA KOGYO K.K. 26 June, 1969 [29 June, 1968; 3 July, 1968], No. 32355/69. Heading F3C. A bolt-action firearm comprises a bolt mechanism 1 mounted in a receiver for longitudinal sliding and rotary locking and unlocking action, the bolt mechanism including a spring loaded firing pin 4 having an engagement part 9 received within a bore 23 of a bolt body 3. The rear end of the firing pin 4 is provided with a cocking piece 6a, rear engaging catch part 6b of which co-operates with a cam recess 29 in the bolt body 3 when the body 3 is in its fully rotated locked position to allow the firing pin 41 to move forward under its spring loading so that the catch part 6b engages a sear 36 of the firearm. On rotation of the bolt body 3 from the locked to the unlocked position a cam surface of the cam recess 29 co-operates with the cocking piece to cause retraction thereof. The engagement part 9 also prevents forward movement of the firing pin 4 until the body reaches its fully rotated locked position whence an engagement slot 25 extending from the bore 23 comes into register with the engagement part 9. When the engagement slot 25 comes into register with the engagement part the firing pin 4 is urged forwardly by its spring so that the cocking piece comes into engagement with the sear. In the construction shown and described the spring of the firing pin 4 is given a torsional force and the forward end of the engagement part 9 and shoulders on the body 3 adjacent the slot 25 form complementary cam surfaces such that on the body substantially reaching its fully locked position the body is rotated forcibly by the spring. Rotation of the firing pin 4 within the cocking piece 6 is limited by the co-operation of a pin passing through the firing pin 4 with a stop on the cocking piece (Fig. 9, not shown). The pin also keeps the cocking piece assembled on the firing pin 4. The cocking piece 6 is partially housed within a bolt sleeve 5 slidably mounted on the firing pin 4, which sleeve 5 is connected to the bolt body 3 by a bayonet-type connection. The bolt body 3 is provided with a handle 24 and locking lugs 28. Other means that is, a circlip (Figs. 19, 20, not shown), a pivotally mounted pin (Figs, 21, 22 not shown), a spring loaded, pivotally mounted stop pin (Figs. 23, 24, not shown) and a pin passing through a transverse cut-out in the cocking piece (Figs. 25, 26, not shown) may be provided for holding the cocking piece on the firing pin.

IPC: A61M5/20
Filed: 1949-12-17
Abstract: 686,998. Hypodermic injection devices. NATIONAL RESEARCH & DEVELOPMENT CORPORATION. Dec. 14, 1950 [Dec. 17, 1949], No. 32428/49. Class 81 (ii). A hypodermic syringe is provided with means for admitting liquid alternately to each side of a reciprocating piston so that as the piston discharges one charge through the needle the next charge is fed to the tube ready for discharge on the return stroke of the piston. A syringe barrel 2 houses a glass tube 31 in which the piston 32 reciprocates.. A rotary valve 17 has two ducts 18, 19 which alternately connect the glass tube 31 in front of and behind the piston 32, by ducts 9, 12 respectively, with liquid supplied under superatmospheric pressure through a duct 14 to the rotary valve 17. Liquid flowing in front of the piston 32 moves the piston 32 rearwardly and discharges liquid through axial and radial ducts 41, 40 in the syringe barrel 2, thence through a duct 12 to the rotary valve 17 and ducts 10, 8 to the needle 6. The rotary valve 17 is then rotated through 90 degrees by a lever 28 so that the glass tube 31 may be charged with liquid on the rear side of the piston 32 and liquid in front of the piston 32 is discharged through the needle 6 as piston 32 moves forwardly. The process may be repeated on further rotation of the rotary valve through 90 degrees. The rotary valve 17 is of tapered form and is actuated by a pawl and ratchet mechanism. The piston 32 may be operated manually in an alternative construction. There is sufficient clearance between the piston 32 and the glass tube 31 to allow a continuous leak of liquid through the needle 6 which prevents it from becoming blocked.

Title: Improvements relating to liquid level gauges
IPC: G01F23/36
Filed: 1936-11-28
Abstract: 480,391. Electric signalling systems. RUSSELL, V. J. S. Nov. 28, 1936, No. 32676. [Class 40 (i)] In a liquid level, temperature or pressure indicator, the effect of variation in battery voltage on the indication of the instrument h is reduced by including a pair of separable, but normally closed contacts a, b, in the circuit, a winding e connected in parallel with the battery being provided to separate the contacts when the battery voltage exceeds a predetermined value. Upon the battery voltage rising, the current in winding e increases, causing the bi-metallic strip f to warp and interrupt the circuit. In a modification, contact a is mounted on a similar strip to f rendering changes in the ambient temperature ineffective. The interrupter may comprise an electromagnet actuating a spring- controlled armature with a time-lag device.

Abstract: 1,008,089. Fluid-pressure servomotor systems. DAWTY ROTOL Ltd. Aug. 17,1964 [Aug. 20, 1963], No. 32913/63. Heading G3P. The displacement of a swashplate or radial cylinder pump 17 is controlled in response to delivery pressure by a piston 24 loaded by a spring 31 and delivery pressure acting on a piston 30 towards maximum displacement. The delivery pressure in line 23 is fed to a chamber 39 and orifice 41 to a chamber 38, a relief valve 42 being provided to maintain a constant pressure in chamber 38 which acts together with a spring 33 as a loading for a valve member 32 having a surface 46 subjected to pump delivery pressure in the chamber 39. The delivery pressure is also fed through a passage 62 and posts 63, in a valve seat 53, to a chamber 56 to act as a land 50 and through an arial bore 57, restriction 59 and parts 60 to a chamber 54 to act on land 49. The flow of fluid from an arial bore 58 leading from the ports 60 is controlled by the valve 32 whereby movement of the valve 32 causes a pressure difference on the lands 49, 50 to move the valve to control the supply or exhaust of fluid to the piston 24. Movement of the piston 24 to adjust the pump acts through lever 68 to move the valve seat 53.

Title: Improvements in and relating to heel nailing or heel attaching machines
IPC: A43D79/00
Filed: 1925-12-30
Abstract: 254,606. Sandt, J. Dec. 30, 1925. Heels, machines for.-A heel compressing and nailing machine has a power driven shaft for moving two members relatively to each other for gripping the heel to be nailed, a second motor driven shaft for operating the nailing mechanism and a single treadle the depression of which successively clutches the two shafts. The pressing member 27, Fig. 1, is carried by a slide 21 raised and lowered by a screw secured to a bevel wheel 19, Fig. 4, gearing with bevel wheels integral with female clutch members 11, 12 cooperating with a double clutch member 13 rotating with but slidable along a driven shaft 1. This clutch is operated by a lever 17 linked to a lever 24, Fig. 1, connected through a spring 61 to a treadle operated rod 60. The free end of the lever 24 enters a groove in the slide 21, preventsthis from turning and co-operates with stops at the ends of the groove to release the clutch when the member 27 reaches either of its extreme positions. The angle of the clutch 11 is more acute than that of the clutch 12 so that greater power can be transmitted to lift the member 27 than to lower it. The lower end of the rod 60 is pivoted to a rod 47, Fig. 7, at the free end of a. link 49 pivoted at 50. The rod 47 is normally linked to the treadle 51 bv a latch 53 connected by an adjustable link 55 with a lever 56 operated by a cam to release the latch at the end of the operation. The rod 47 is also connected by a pair of links 46, normally bent by a spring 48. to a bell-crank lever 36 provided with a plate 37. This plate is normally in the path of a plunger 34, Fig. 6, on a member 32 keyed to a shaft 2, Fig. 1, on which is an eccentric 28 operating the nail driving plunger 31. Partial depression of the treadle 51 pulls the rod 60 downwards and engages the clutch 13 to depress the clamping member 27 on to the heel of a shoe positioned on the jack 70. If the work is not properly positioned the treadle is released, when a spring 63 reverses the clutch to raise the clamp for repositioning and clamping. Further depression of the treadle compresses the spring 61 'to increase the clamping pressure and straightens the links 46 to operate the bell-crank lever 36 and allow the plunger 34 to engage a projection inside the rim of a flywheel constantly driven by the pulley 3. The shaft 2 is thus driven for one revolution, operating the nail driving plunger. At the end of the revolution the cam-operated lever 56 releases the latch 53 allowing the rod 60 to rise and the plate 37 to engage the plunger 34, when the member 32 is stopped by a brake. The shaft 1 is driven from the pulley 3 by a belt provided with a pair of jockey pulleys.
