Title: Improvements in Electric Arc Lamps.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-02-27
Granted: 1904-02-18
Abstract: 4645. Carolan, E. A., [General Electric Co.]. Feb. 27. Arc lamps.-A three-carbon enclosed lamp for use on threephase circuits is provided with an induction motor for feeding the carbons simultaneously. The carbons are arranged to proj e c t symmetrically through insulating- bushings 21<1> into the cup 10, in which is held by screws a block of refractory material having, as shown in Fig. 5, channels for the carbons and a central cup-shaped depression to serve as a reflector. The carbons are held in insulated clips 20, formed of sheet metal and movable along the bars 16 by means of the rack bars 18 gearing with the spiral gear wheel 30. The field magnet 2 consists of a laminated iron ring with six inwardly-projecting pole-pieces, the discs being held between end plates 4, 5 provided with brackets 6, 8. The coils are wound alternately in two sets, one set in series with the carbons and the other in shunt, but so connected that the magnetic fields of the two sets rotate in opposite directions. The currents pass in series through steadying inductances (not shown) and the winding of the motor to the carbons. The armature, of the squirrel-cage type, is carried in bearings in the brackets 6, 8, and connected through reduction gearing, as shown, with the spiral gear wheel 30. The enclosing-globe 32 is held against the cup 10 by springs 33 and a stirrup 34.

Title: Improvements in Controlling Devices for Air Brake and other Fluid Pressure Systems
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-03-20
Granted: 1904-02-25
Abstract: 6489. Carolan, E. A., [General Electric Co.]. March 20. Electric locomotives and motor vehicles.-Relates to fluid-pressure systems, such as air-brake systems for electric cars &c., where a compressor is worked by a shunt-wound electric motor and the fluid is maintained at a constant pressure by automatic means, the motor being thrown into circuit when it falls and cut out when it rises beyond certain limits. A. switch S operated by a pressure governor C, controls the shunt-wound motor A, which drives the compressor D, while a valve F controls the supply of compressed fluid to a cylinder G, the piston of which moves the contact-arm 38 of the rheostat B and so regulates the speed of the motor. The lever 31 of the switch is held in its extreme positions by a catch 33, which is pivoted at 34 and terminates in an extension 35 in proximity to a trip 36, so that, when the pressure falls below a predetermined amount, the trip releases the catch 33 from the lever 31, which is thrown down, closing the switch. Current then passes from the supply wire through the wire 12 and blow-out magnet 12<a> to the switch, and thence to the point 13<a>, where it divides, part passing through the wire 14 and the field of the motor, and part through the rheostat and the motor armature. All the resistance of the rheostat is then in circuit, but, when the lever 31 is actuated, the stem of the valve F is drawn down closing an opening 27 to the atmosphere, and opening a passage 28, so that air from the compressor D passes by a pipe 24 to the cylinder G. The piston is thus forced outwards against the pressure of a spring 41, and gradually cuts out the resistance of the rheostat. The motor, thus started, actuates the compressor D to raise the pressure of the system to the desired extent, and when this point is reached, the governor C opens the switch S and the motor circuit, and simultaneously exhausts the cylinder G. to atmosphere through the opening 27, and cuts off the compressed-air supply. The spring 41 then returns the piston and the rheostat arm to normal position.

Title: Improvements in Friction Clutches
Inventor: HUTCHINS THOMAS WILLIAM SKIMER
Filed: 1903-04-07
Granted: 1904-04-07
Abstract: 8004. Hutchins, T. W. S., and Adams, W. April 7. Clutches.-A friction clutch is automatically put into action by variation in speed of the driving- shaft. The pulley 2 is mounted loosely, and the part 3 of the clutch slides longitudinally, on the sleeve 1 key ed to the shaft. The levers 4, centered at 6, tend, when revolving, to throw the clutch into operation by centrifugal force, against the action of the the springs 8. The movement of the levers is controlled hy the governors 7, which are pivoted on the spindles 10 attached to the brackets 14, and have lips engaging the bars 13 fixed to the levers 4. When sufficient speed is attained, the governors expand against the action of the springs 9, and release the levers 4, which in turn expand and throw the clutch into action. In a modification, the springs 8 are normally in tension across the centre 6, and draw the clutch members together when the levers 4 are thrown out of line by the governors 7.
