Abstract: 340,434. Lubricating universal joints. RANSOMES, SIMS, & JEFFERIES, Ltd., and GARRETT, F. A., Orwell Works, Ipswich. Feb. 4, 1930, No. 3789. [Class 12 (ii).] In a Hooke's joint for cardan and other shafts, wherein the centre part of the cross is formed as an oil reservoir whence oil is centrifugally fed to the pins, the oil is fed in small doses under the control of a check valve actuated intermittently under its inertia by the vibration set up by the angular transverse oscillation of the cross. A valve box 9 houses opposed valves 11 arranged on or near the joint axis and pressed on to their seats by a light spring 13. The valves have heavy slightly conical spigots 11. The strength of the spring and the valve weight may be so arranged that the valve only opens when a predetermined speed is reached. The valve box is carried centrally on ducts 8 through which oil flows centrifugally in small doses from the reservoir 7 through the restricted opening 15 to the cross pins 2. There are hardened steel discs 4 at the ends of the pins and packing 5 is provided for the closed bushes 3. The reservoir has a side screw-plugged filling hole and an anti-vacuum valve 21 as claimed in Specification 338,968, [Class 12 (ii), Lubricating passages &c.]. To avoid starvation of the valve due to tendency of the oil to cling to the sides of the casing when stationary, radial wires 23, shown dotted, are provided. In a form in which a single check valve is used, its spigot is wholly enclosed in its housing. According to the Provisional Specification, the pins, discs, and ducts 8 may be provided with oil-holes or ducts to lead oil to different parts as required.

Filed: 1935-02-06
Abstract: 434,329. Machine guns. PARR, C. E., 169, Higher Road, Urmston, Manchester. Feb. 6, 1935, No. 3809. [Class 92 (ii)] A recoil-operated machine gun has a cartridge conveyer ring 9, see plan, Fig. 4, with a number of radial firing chambers 10 which are brought successively behind the barrel 1 by rotation of the ring about a vertical axis, the cartridges being fed radially to the chambers, when the gun is in action, from a hopper 22, Fig. 2, by way of a shoot 24. The cartridges in passing down the shoot are supported by their rims and change their inclination from vertical to horizontal before resting on a tray 25 from which they are forced into the chambers by a pusher 30 reciprocated by the recoil of the barrel. The recoiling parts comprising the barrel 1, breech block 4, conveyer ring 9, and hopper 22 are mounted on a carriage 2 which slides on discharge in guides on the mounting 3 which carries a pawl 44 engaging a ratchet wheel 43 on the carriage to rotate the conveyer ring. The breech block has an eccentric surface 19 to extract the empty cartridge cases gradually from the chambers as the ring 9 revolves in the direction of the arrow 47, the cases ultimately falling through apertures 12. The chambers remain empty during a portion of the rotary movement to facilitate cooling. As an empty chamber arrives opposite the tray 25, the pusher 30, operated by fixed pins 34 and bell-crank lever 35, loads the chamber and a rod 40 connected to the pusher stresses a spring 29 connected to an arcuate pivoted arm 26 for moving the cartridges down the shoot. A handle 46 serves for moving the carriage 2 back by hand for starting the gun. Firing is effected by a trigger-operated lever 52, Fig. 1, carrying a depending rod 55 with pins 57 engaging a pivoted rod 50, a lump on which contacts with the sear 62 as the parts return after recoil.

Title: Gear roll chamfering
IPC: B21H5/00
Filed: 1973-01-25
Abstract: 1386043 Rolling gears LEAR SIEGLER 25 Jan 1973 [27 Jan 1972] 3838/73 Heading B3M A composite rolling and chamfering die enables teeth to be rolled on a gear-wheel, and the teeth to be chamfered at one end, the die having a conventional central section to one side of which a chamfering die section is attached. The die may have a chamfering section 80, Fig. 2, on either side of the central section 14. The gear-wheel is initially rolled by the central section, is traversed axially to chamfer the teeth at one end, and is traversed in the opposite direction to chamfer the other ends of the teeth. The gear is finally rolled by the central section to remove protuberances caused by the chamfering dies and to finish form the teeth. The die teeth 104, Fig. 4, may be helical, whereas the aligned chamfering teeth 118 are tapered. This causes the acute edges of the gear teeth 106 and 108 to be chamfered by the surfaces 114, when the teeth are traversed laterally. If a spur gear is rolled, slight chamfers may be provided on all four corners of each tooth. The sections 80 are attached by a transverse pin 90 to the central section 14 and are angularly adjustable by means of pairs of screws 94 (Fig. 3, not shown). The die 14, Fig. 1, is carried in a machine frame 10, and the gear W is traversed axially relative to the die. The gear is supported on a table 60 which can be fed laterally by a screw 48 or can be rocked about a pivot 62, either motion leading to a suitable traversing motion. The table 60 is also able to be fed vertically by a toggle assembly 28 and to be adjusted vertically by a screw 24.

Abstract: 433,141. Protective cut-out arrangements. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, Newcastle-on-Tyne, and GREGORY, R. W., Makendon, Causey Way, Hexham, Northumberland. Feb. 9, 1934, No. 4346. [Class 38 (v)] [See also Group XXXVI] An electric transmission or distribution system having an earthed neutral point is protected against transient earth faults by providing an automatically reclosing circuit-interrupting device in the neutral earthing connection, such device acting to break the connection and quickly remake it, on the occurrence of an earth fault. In the arrangement shown in Fig. 1, the neutral point A is connected to earth through a fuse C and switch arm D. In the event of an earth fault, the fuse blows and momentarily interrupts the circuit, which is immediately reclosed by the movement of the switch arm D on to a contact D<1> connected to the neutral point A. In an alternative arrangement, Fig. 2, a series of fuses C, E, G are successively brought into circuit by the release of switch arms D, F, a further switch arm-connecting the neutral point A directly to earth on the blowing of the last fuse G. A hand-operated switch J, which may be interlocked with the cover of the tank B containing the switches and fuses, is provided to enable the neutral point A to be earthed independently of the switches and fuses. In a modification, Fig. 5, the neutral point is earthed through a fuse K connected to a pivoted latch lever L which normally holds a second fuse M in an inoperative position. When the fuse K blows, the latch lever is released, and the fuse M drops into a position in which it bridges the gap in the circuit caused by the blowing of the fuse K.
