Title: Improvement in Controllers for Electric Motors.
Inventor: DAVIS HARRY PHILLIPS
Filed: 1898-08-30
Granted: 1899-08-05
Abstract: 18,584. Davis, H. P. April 25, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Motors, controlling.-Apparatus for controlling the power and speed of electric motors, particularly railway motors of large capacity. The switch for varying the resistance in circuit with the motors is separated from the switch for varying the connections of the motors, and the two switches are connected by gearing so that the operation of the resistance-varying switch will at the proper time cause the second switch to alter the connections of the motors from series to parallel or vice versÔ. In order to reduce sparking, the resistance is divided into a number of sections, and a portion of each section is cut in or out'simultaneously as the operating-handle is revolved. Reversing and cut-out switches are also provided, and these are connected by interlocking devices with the switch for varying the connections. Fig. 2 shows the form of apparatus employed for controlling a pair of motors. The operating-shaft 3 carries, by means of radial arms 9, four contact-brushes 10, which move over four sets of resistance contacts 7. A step-by-step movement is ensured by a lever 13, pivoted to one of the arms 9 and engaging with notches in a fixed ring 11. The shaft 3, by means of segmental bevel gearing, operates a shaft at right-angles to it, and the latter is geared to the spindle 25 of the contact-drum d, which varies the connections of the motors. The reversing-switch d<1> is actuated through segmental gearing from a shaft 29, and is connected with the central switch d by interlocking gear, which prevents movement of the latter during reversal. The switch d<2> for cutting out one or the other of the two motors is similarly actuated from a shaft 29<a> and also interlocks with the switch d. After the motors have been changed from series to parallel, their field magnets are shunted through resistances by a further rapid movement of the switch d, communicated to it from the shaft 3 by additional bevel bearing. A modification of the controller for use with four motors is also described. In this form, a combined cut-out and reversing-switch is employed on each side of the switch which varies the motor connections.

Title: Improved Methods and Means for Carburetting Air and Enriching Gas for Illumination, Heating and Power Purposes.
Inventor: HARTRIDGE JAMES HILLS
Filed: 1901-01-18
Granted: 1901-12-31
Abstract: 1173. Hartridge, J. H. Jan. 18. Carburetting.-Air or gas is carburetted by a spraying or an absorption method, or by a combination of both. The spraying process takes place in a cylindrical vessel a, Fig. 1, having a bell top b dipping into a water trough c, which has outlets d at different levels. The bell is adjustably weighted. The liquid hydrocarbon enters through the tube j, and rises to a level governed by the ball cock l. The air or gas to be carburetted enters through a tube e having a nozzle so arranged as to draw liquid up the suction pipe m, the nozzles of the two pipes being set at about a right-angle. The pressure in the carburetter is above that of the atmosphere ; that of the air is much greater. The pipes e and m are preferably arranged so as to give the sprayed mixture a whirling motion. The carburetted air or gas leaves through the outlet pipe i. The absorption method takes place in an apparatus represented in Fig. 3, wherein the hydrocarbon is fed into a vessel q up to a certain height determined by the ball cock l from a supply tank p, and then flows slowly past a valve 1 down a coiled tube o immersed in water of any desired temperature in a tank a. At the lower end of the tube, a connection is made with the air or gas under pressure. The upper part of the coil and the top of the vessel q are connected by a tube 2. In a modification, the tube is kept full of liquid, the air bubbling upwards through it. In another modification, the air bubbles may be made to take a spiral course through the hydrocarbon contained in a cylindrical annular vessel by means of a spiral inverted trough or a spiral device placed in the inner vessel. In the first case, the inner vessel, and in the second, the annular space, contains heated water. An arrangement of levers is described whereby the supply valves on the hydrocarbon pipe and on the air pipe are simultaneously operated and adjusted according to the demand.
