Abstract: 187,590. Sullivan Machinery Co., (Assignees of Holmes, M. P.). Oct. 17, 1921. [Convention date]. Operating clutches. - In clutch controlling- mechanism, the operative end of the clutch shifting-lever is movable in the direction of the length of the lever relatively to its pivoted end. As applied to a mining-machine, a forked clutch lever 6, comprising relatively rotatable telescopic sections 17, 18, is adjustably pivoted at 7 to the machine frame 1, and is rocked for actuation bv an eccentric 8. This eccentric engages a hole 19 in the lever-part 17 and is mounted on a transverse shaft 9 carrying a level wheel 12, Fig. 1, adapted to be rotated by a toothed quadrant 11 on an operating- lever 10. The forked lever 6 carries rollers 16, Fig. 2, contacting with a flanged member 13 integral with a part 14, which actuates by toggles 15 the driving-member 3 of an expanding friction clutch. The driven clutch member 2 carries a gear wheel 4 associated with the feed-mechanism of the machine and adapted to be connected by the clutch to a vertical shaft 5. The mode of connection of the parts 17, 18 obviates the provision of a slot for the eccentric 8 and equalizes the pressure from the two rollers 16. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also a reference to U.S. Specification 1.347.811. This reference does not appear in the Specification as accepted.

[Also in Group XXV] A rivet comprises a pin 12, Fig. 1, with a head 24 and a stem having a plain cylindrical part 28 followed by grooves 34, a break-neck 38 and a pull-shank 42, and a collar 14 having a substantially uniform external diameter and symmetrical end portions 46, 46<SP>1</SP> of gradually increasing wall thickness in the directions from the ends toward the centre of the collar. The collar is swaged into the grooves 34 after the parts 20, 22, secured by the rivet, are clamped tightly together and the head engages the appropriate one of said parts. Swaging is effected by an anvil 52 of a tool 50 having a surface 54 engaging the collar such that, as the collar is pushed and the pin pulled, the collar will not be swaged into said grooves until a force is achieved adequate to clamp the parts &c. After completely swaging the collar (Fig. 6), a continued pull on the pin fractures the breakneck. Specification 629,098 is referred to.

Filed: 1924-11-07
Abstract: 230,011. British Thomson-Houston Co., Ltd., (Assignees of Hull, A. W.). March 1924, [Convention date]. Vacuum tubes. - A screening grid between the control grid and the anode of a thermionic valve, and the leads for the electrodes are so arranged that, by applying a suitable potential to the screening grid, capacity coupling between the control grid and anode is eliminated. For this purpose, the screening grid 5, Fig. 1, extends beyond both ends of the control grid 3 and anode 4, and the lead 18 for the control grid is connected at the opposite end from the foot 6 in which the anode lead 20 is sealed. The screening grid 5 is mounted on supports 12, 13 embedded in the foot and spaced by a block 11 of insulating material, in which the supports for the control grid and cathode are embedded. The potential of the screening grid is maintained slightly positive to that of the control grid. In a modification, the lead 18 passes through the foot and is sealed inside, and insulated from, a metallic sheath, which may be earthed or maintained at a fixed potential, for instance, by employing it as a connection between one end of the cathode and the heating battery. In another modification, a metallic coating on the inside or outside of the wall of the bulb is connected with the screening grid, so as to intercept elertrostatic lines of force passing from the anode around the ends of the screening grid. The coating may be maintained at, or near, earth potential. In the arrangement shown in Fig. 4 the screening grid consists of annular discs 29 threaded on rods 30. Discs 31, of a diameter nearly equal to that of the bulb, may be mounted at the ends of the grid; similar discs may be used in the arrangement shown in Fig. 1. Specification 188,707 is referred to.

An electromagnetically actuated valve comprises a valve closure, which may be a single ball 8, Fig. 1, movable between seats 9, 11 or a double ball valve, controlling flow from a fluid supply 2 to an outlet 3 and from the outlet 3 to exhaust 4. The valve is actuated by a solenoid 22 and an armature 16. The electrical circuit, Fig. 5, comprises a non-linear resistor 43, whose resistance reduces in accordance with the magnitude of the voltage, connected in parallel with the solenoid coil 22 and half-wave rectifiers 41, 42 connected in series and parallel with the coil. The resistor 43 comprises electrodes 44, 45 having separate connections 48, 49, 51, 52 to the supply 46, 47 and the solenoid whereby in the event of one connection breaking, no current flows to the coil. The arrangement of rectifiers and resistor reduces the energy of any spark which might occur in the solenoid circuit. The rectifiers and resistor are in a housing clamped to the valve body. The coil is wound on an aluminium bobbin 19 as a precaution against sparks. The valve may be actuated manually by a push button 31. Specification 958,124 is referred to.
