Patent GB-190503180-A (GB)
Title: Improvements in and relating to Centrifugal Pumps.
Inventor: HARRIS ELMO GOLIGHTLY
Filed: 1905-02-15
Granted: 1906-02-15
Abstract: 3180. Harris, E. G. Feb. 15. Centrifugal pumps.-In a centrifugal pump, the amount of discharge is regulated by a vane 13, which extends into the delivery pipe and may be removable and replaceable by others of different sizes. The vane may be pivoted, as at 14, and adjusted by means of a pinion 16 engaging with a rack 17. In the case of a compound pump, the regulating-vanes are operated by a common shaft 15. The pump case is provided with a tangential inlet 10, arranged eccentric to the axis of the impeller and so proportioned that the tangential velocity of the entering water equals the velocity of the wheel where it enters. This opening is preferably so arranged that the angular extent of the inlet opening is approximately equal to the angular extent of the discharge, as shown in Fig. 3, in which case wheels with radial blades are used, but the opening may be differently proportioned and arranged on the opposite side of the wheel as shown in Fig. 8, in which case wheels with helical blades are preferably employed. The pump is primed by means of a pipe 21 which may be connected by an ejector 22 or by a pipe 27 to a suction pump. The pump wheel consists of a disc 8 having inclined vanes 12 ; air under pressure is admitted to the back of the wheel. which is roughened or provided with shallow radial blades for the purpose of expelling any water at the back. In the case of a compound pump, the blades 12 are on opposite sides and inclined in opposite directions, and air is led first by the pipe 25 to the back of the high-pressure pump, any which leaks past the wheel being drawn from the centre by the pipe 24 and delivered by the pipe 23 to the back of the low-pressure pump; finally, any air which leaks past the low-pressure wheel is removed by the ejector 22. Gauges 26 indicate the progress of air through the pump. In the case of the threestage pump, blades are provided on both sides of the third wheel ; in this case, no air is intentionally led into the case, but any air which may leak into it is removed by tubes connected to the centre of the casing.

Title: Improvements relating to the Starting of Internal Combustion Engines; especially applicable to Motor Cars.
Inventor: DADGE BENJAMIN NELSON
Filed: 1906-09-21
Granted: 1907-08-08
Abstract: 20,937. Dadge, B. N. Sept. 21. Gas and like engines, starting and igniting in. To prevent road-vehicle and other engines from being started while in gear, provision is made to prevent the closing of the ignition circuit until the speed-varying lever is in its neutral position. In all cases, it is necessary to break the ignition circuit when stopping. In Figs. 1 and 2, the apparatus is shown applied to a road-vehicle engine, the lever 1 having broken the igniting-circuit 2, 5, 15, 21, 20, 12, 11, 18, 19, 17 by being moved over the contact 4 into its extreme left-hand position. From this position the lever can move into engagement with the contact 4, but any further advance is arrested by the projection 6 and lever 7, 9. To close the igniting-circuit, the speed-varying lever 22 is moved over to its central position, thus disengaging the engine, if this has not already been effected, and completing the electro-magnetic circuit 13, 11, 18, 19, 17, 2, 4, 10 through the contacts 23, 24. The electro-magnet 10 being excited releases the lever 1, which' may then move over to complete the igniting-circuit through the contact 5. A separate switch may be inserted in the electromagnetic circuit, so as to break the circuit in the event of the levers 1, 22 being so arranged as to otherwise close the circuit when-the engine is standing idle. Dry-cells may be used to excite the electro-magnet, when a magneto is used 'for generating the igniting-current.
