Inventor: FARMERY GEORGE KENNETH
IPC: F16T1/14
Filed: 1962-01-30
Abstract: 1,025,843. Condensate drains. CLAYTON DEWANDRE CO. Ltd. Jan. 18, 1963 [Jan. 30, 1962], No. 3442/62. Heading F4U. [Also in Division G3] Condensate drains from an air reservoir 3 into a chamber 4 via a seat 7, which chamber leads to an inclined passage 12 opening to atmosphere through a further seat 11. A rubberfaced plunger 13 is disposed in the chamber 4 to coact with the seats, which plunger is operated by a diaphragm 15 subjected to reservoir pressure under the control of the governor valve of a compressor unloading device. The plunger is loaded to the position shown by a light spring 21. A filter 8 is disposed between the reservoir 3 and the inlet 5 to the chamber 4 whilst the passage 12 is shrouded by a rubber sleeve 22 to prevent the ingression of foreign matter. During charging of the reservoir no pressure acts upon the diaphragm 15 and the parts assume the positions shown; when a given reservoir pressure is attained the governor valve causes reservoir pressure to lift the diaphragm and hence the plunger 13 so opening the seat 11 and closing the seat 7 whereupon any water in the chamber 4 is discharged by the residual air pressure in the chamber.

Title: Improvements relating to copying lathes and like machine tools
IPC: B23Q35/10
Filed: 1953-02-06
Abstract: 722,881. Copying lathes. BECKER, H. Feb. 6, 1953 [Feb. 7, 1952], No. 3453/53. Class 83 (3). A copying lathe &c. comprises flat cams and feeling pins for transverse and axial movements of the tool and in which the cams for producing non-circular or eccentric cross-sections of the .work are rotated in synchronism with the work, while those for producing surfaces of revolution on the work are fixed, the feeling movements of the pins being combined to produce a'resultant movement of the tool. A longitudinal slide 32, Fig. 7, is mounted on bed guides 31 and may be moved by screw 37. A cross slide 33 is carried by the first slide and is fed by a screw 38 driven in either direction by a motor 39, Fig. 8, through an electromagnetic clutch 40, 41. The latter is controlled by a switch 42 operated by an arm 43 of a gear sector engaging a rack 44. The rack 44 in Fig. 8 is equivalent to the rack 27 of Fig. 1, and derives its movement from a stationary rack 17 in a casing 1 and a series of further slidable racks and pinions mounted on tracer pins such as 18, 20, 22, &c. The tracers are moved, either by flat cams 12, 14, 16, driven in timed relation with the work, or, by relative sliding movement over fixed templates such as 13, 15. The final movement of the last rack, which operates the control switch for the feed clutch, is an algebraic summation of the tracer movements. The cams are used to control tool movement in elliptical, eccentric, or other out-of-centre movements while the templates control the tool movements to obtain the plan shape of the work which in the example shown, Fig. 2, is a crankshaft. The tool slide 34 may be controlled similarly by feeler pins 54 ... 56, Fig. 8, cooperating with templates - VII, VIII, and rotating cam X.

Title: Cartridge-feed mechanism for automatic firearms
IPC: F41A9/31
Filed: 1937-02-10
Abstract: 490,221. Automatic guns. S O C . D'EXPLOITATION D'INVENTIONS MECANIQUES. Feb. 10, 1937, No. 3945. Convention date, Feb. 17, 1936. [Class 92 (ii)] A feed mechanism for automatic firearms comprises a drum which is rotated step-by-step to feed a cartridge belt or holder to means adapted to strip the cartridges from the belt and to feed them to a shoot leading to the loading mechanism of the gun, the drum being wound by an external source of power entirely independent of the movements of the gun. According to one construction, the drum 1, Fig. 1, is driven by a spring motor 29, the spring of which is maintained in tension by an electric motor which functions when the tension becomes lower than a predetermined value. A rod 30 pivoted to the crank of the spring motor is connected to one end of a pivoted lever 9. A rod 8b connected to this lever is secured to an externally screw - threaded sleeve slidably mounted on a fixed spindle 6 and engaging with an internally screw-threaded bushing 7 also mounted on the spindle. The reciprocating movements of the sleeve, effected by the lever 9, thus tend to impart a rotational movement to the bushing and, by means of pawls 4, 5, the bushing imparts a step-by-step rotary movement to the drum. The upper end of the lever 9 engages in a slot of a shackle 19 integral with a plunger 20 which is urged by springs 21 towards a stripping device 14. The latter has a shaft 23 which engages in an endless slot of rectangular contour formed in a fixed frame A and which is engaged by the forked end of a lever 15 pivoted to a block 17 slidably mounted on the frame. The pivoting movements of the lever and the sliding movements of the block are effected by the plunger 20 and the arrangement is such that the cartridges 11a are stripped from the belt 11 and urged longitudinally along slots 1a in the drum'to the entrance of the shoot 12, through which they are urged by the drum to the loading mechanism of the firearm. In a modification, Fig. 3, the drum 33 is urged constantly in a clockwise direction to feed the cartridges 54 to the shoot 36. The cartridge belt comprises a number of links, each having a tongue 51, and a spur 53 adapted to engage with a perforation 52 in an adjacent link. The cartridges are gripped by claws 50 and, when in position, serve to maintain the spurs in engagement with the perforations. When the drum rotates, the cartridges are stripped by an inclined surface 35 and fed to the shoot. The Specification as open to inspection under Sect. 91 describes also a construction in which an endless-conveyer belt is employed to feed the cartridges, one at a time, to an oscillating member which conveys them to the shoot leading to the loading mechanism. A construction of shoot is also described for feeding the cartridges to two similar coupled firearms. This subject-matter does not appear in the Specification as accepted.
