Title: Improvements in Devices for Filtering or Separating Dust from Air and Gases.
Inventor: FRASER WILLIAM
IPC: B01D46/04
Filed: 1912-09-10
Granted: 1913-09-10
Abstract: 20,652. Fraser, W. Sept. 10. Filtering.-In the automatic cleaning of the filter bags of vacuum cleaning and other apparatus by means of brushes, relative movement between the bags and brushes is obtained from a turbine-wheel driven by the current of air or gas that is being cleaned, the turbinewheel being connected through reducing-gear either to the bags or to the brushes. In the form shown, a stationary filter consisting of fabric c stretched over a perforated cylinder is suspended in a depositing-chamber a having a dust-laden air inlet c and an inspection plate b. The purified air issuing through a nozzle f drives a turbine-wheel h connected through reducing-gear l, m, m, o, p, q to a brush g carried by an internally-threaded ring s mounted upon ball bearings upon an annular ledge of the chamber. The turbine-wheel may be mounted so that it is driven by the incoming dust-laden air. The wheel and gear are preferably protected by a reticulated cover v.

Abstract: 9478. Imray, O., [Metallurgica Bresciana giÓ Tempini, Soc. Anon.]. April 22. Breech actions, sliding barrel and breechblock.-Consists in providing automatic pistols with (a) a special safety-device controlled by the magazine, (b) special means for elevating a combined ejector and catch for holding the bolt open when the magazine is empty, and (c) special means for locking a sliding bottom plate for the magazine. The safety comprises a flat spring 38, Figs. 6 and 7, mounted in a cavity in the wall of the casing that is adapted to receive the magazine. This spring carries two projections 39, 40, one of which engages the wall of the magazine, and the other the trigger 15 in such a manner that the trigger is free only when the spring is retained in its cavity by reason of the magazine being in position. The combined ejector and bolt-catch 31, Fig. 2, is raised by a spring plunger 28 in the cartridge lifter. When the lifter is near the top of the magazine, this plunger is pressed by its spring through a slot in the rear wall of the magazine and engages a shoulder on the ejector. The sliding bottom plate 24 is formed with a hole 25, Fig. 3, with which engages a projection on a plate 27 which is pressed down by the cartridgelifting spring 23.

Title: Improvements in or relating to Apparatus for Indicating the Presence and Estimating the Proportion of a Gas Admixed with Air or other Gases.
Inventor: WEBSTER HENRY ROBERTS
IPC: G01N7/10
Filed: 1913-11-13
Granted: 1914-11-13
Abstract: 26,001. Webster, H. R. Nov. 13. Gas analysis.-In a gas-testing apparatus of the diffusion type, continuance of the indication is obtained by arranging that the magnet energized by the current passing through the diaphragm and adjustable contact-rod holds the diaphragm against the rod and so maintains the circuit; or the armature of the magnet may be arranged to make and maintain contact in a shunt circuit, the lamp or other indicator being in that part of the main circuit not replaced by the shunt. In the construction shown, the diaphragm c, when making contact with the rod k energizes the magnet q. The armature w of this magnet forms part of a shunt circuit y and, when attracted, closes it, and so maintains the signal light p until the shunt circuit is opened. This is effected by rotating a spindle l on which the armature is mounted, so as to remove the armature away from the magnet. The contact-rod k is adjustably mounted, the amount of adjustment being determined by a scaled head n. To prevent danger from sparking at the connexions, the whole of the apparatus, except the porous vessel, is enclosed in an air-tight glass cylinder e. A U-tube filled with mercury may be used in the place of a flexible diaphragm, the legs of the tube having different diameters to increase the sensitiveness of the apparatus.

Abstract: 1363. Griesbach, R. C., and Venner Time Switches, Ltd. Jan. 17. Mechanically tripped switches.-A switch in a prepayment electricity meter is set during prepayment and mechanically tripped at the conclusion of the supply. During prepayment, a disk 29 with a gapped rim 30 is set forward so as to remove the gap 31 from opposite a pin 44 on a floating lever 37 pivoted to the arm 39 of a spring-controlled bell-crank lever 40. A pin 12 on a flange 11 of the coin drum then rocks the bell-crank 40, and, the pin 44 being brought into engagement with the rim 30 of the disk 29, a pin 36 on the lever 37 rocks a lever 34, Fig. 4, which moves a spring contact 32 into engagement with a fixed contact 33 and closes the consumer's circuit. The parts are retained in this position by a catch 46 which co-operates with a pin 45 on the lever 37. The working of the meter gradually returns the disk 29 until at the conclusion of the supply the pin 44 escapes through the gap 31, and the switch is tripped open.

Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: PATERSON THOMAS WATSON
IPC: F02M3/08
Filed: 1915-07-20
Abstract: 10,493. Paterson, T. W. July 20. Spray carburettors.-A primary and a secondary jet are provided, the flow of fuel from the primary jet increasing, and that from the secondary decreasing, with increase of suction, and vice versa, and the secondary jet supplies, in addition, a by-pass leading to the periphery of the throttle valve. Float-feed apparatus is also described. The fuel nozzle comprises two tubular portions 7, 8, of which 8 is screwed into the passage 6, and. 7 is adjustably screwed into the casing 8<a>, adjustment of the part 7 being necessary to vary the spraying-orifice 15 between the two parts. The part 7 has an extension 7<b>, Fig. 3, which enters the lower part 8 and also surrounds a tube 9, which extends through the whole nozzle and is open to the atmosphere at its upper end. Between the extension 7<b> and tube 8 is another tube extending from the plug 11, shown more clearly in Fig. 3, the whole of the tubes forming annular chambers a, b, c. The annular chamber a is fed from the float chamber through restricted passages 13, 14 in the plug 11, which are sufficiently large for maximum delivery, and the chambers b, c are fed through an orifice 12, the chamber c communicating through extension 7<b>, chambers d, 18, and passages 19, 20, 21, Fig. 1, with the edge of the throttle valve 22. At starting, this by-pass only is in action; but as the throttle is opened, the by-pass is cut out, and fuel flows through the annular passages a, b to the outlet 15. With an increase of suction, the flow through a increases, but that through b decreases, owing to air passing down the tube 9 impinging on the orifice 12 and retarding the flow therethrough. On 400 a decrease of suction, the flow through b increases and that through a decreases. The tube 9 is adjustable to vary the delivery through b. Fuel accumulates in the chambers a, b, c when the engine is stopped, and the amount of mixture through the by-pass is determined by adjusting the extension 7<b>, the lower end 7<c> of which is bevelled to allow air from 15 to flow through with the fuel. The float valve 4 is guided in the stem 25, controls the passages 26, 27, and is independent of the floatchamber cover.

Abstract: 17,209. Schweizerische Industrie Ges. Dec. 16, 1914, [Convention date]. Disk apparatus.-The helical blades of rifling-rods for rifling gun barrels are ground while in position on the rod, in a machine in which the rod and the grinding-tool are moved relatively to each other in accordance with the pitch of the blades. The rod 7 is gripped in a pair of sleeves 5, 6 mounted for rotation in standards 3, 4. The sleeve 5 is screwthreaded to the same pitch as the rifling-blades and works in a corresponding nut 20 secured in the standard, so that longitudinal movement of the sleeve and rod is accompanied by the corresponding rotary movement. The grinding-disk 16 is mounted on a compound slide-rest, and the standards 3, are carried by a slide 2, which may be adjusted longitudinally to bring the blade under treatment into correct position in reference to the disk, and then locked by clamps 24. The nut 20 is formed with a flange having two notches adapted to engage a catch 22, whereby it may be locked in two positions 180 degrees apart. The grinding-disk may be moved relatively to a stationary rifling-rod in accordance with the helical line formed by the blades, or one of the two parts, disk or rod, may be moved longitudinally and the other rotated.
