Title: Improvements in Centrifugal Governors.
Inventor: LLOYD GUY ERNEST
Filed: 1902-07-28
Granted: 1903-06-04
Abstract: 16.741. Lloyd, G. E. July 28. Governing compound engines. In the arrangement shown in Fig. 33, the throttle valve 40 has on its stem a piston, the upper side of which is subject to boiler pressure, while the lower side is subject to receiver pressure. When the valve 40 is lowered to throttle the steam, the pressure in the receiver is reduced, and the valve is thus further lowered by the pressure on the upper face of the piston, until steam is admitted through the pipe 48 to the cylinder 49. The piston in this cylinder controls a throttle valve in the low-pressure cylinder steam pipe. In a modification, the piston is not on the valve stem, but is connected to the valve by a lever, and serves as a distributing-valve for the cylinder 49, the piston of which may control gear such as described in Specification No. 12,620, A.D. 1901.

Title: Improvements in or relating to Alternate Current Traction Systems.
Inventor: MORDEY WILLIAM MORRIS
Filed: 1902-11-04
Granted: 1903-09-17
Abstract: 24,112. Mordey, W. M., and Hansard, A. G. Nov. 4. Electric railways and tramways.-Relates to alternate-current traction systems, and consists of means for reducing fall of pressure in the return rail or conductor. Fig. 1 shows a diagram of the circuits in the case of a single-phase railway or tramway, having the supply conductor 2, and return rail 4 with return feeder 5 in parallel therewith. Return current is diverted from the rail 4 to the feeder 5 by causing the return current in the rail 4 to set up an assisting electromotive force in the feeder. This is effected by means of a transformer 6 having two windings 7, 8 of opposite direction, in series respectively with the rail 4 and feeder 5, the return current being diverted from the rail 4 to the feeder 5 in a ratio corresponding to the ratio between the number of turns in the coils 7, 8. When the return rail is in sections, these sections may be connected in parallel through coils 7, each to a separate return feeder having its coil 8, or to a common return feeder with its coils 8 in series ; or the return rail sections may be connected through the coils 7 in series, the coils 8 being in series with a common return feeder, Fig. 4, or each in series with a separate return feeder. The invention is equally applicable to a three-phase system.

Granted: 1903-01-15
Abstract: 24,789. Schr÷ter, M. Nov. 11. Fire-escapes and the like.-Relates to a ladder mounted to run on a rail in front of a building, so that it can be automatically brought opposite any window by pushing the button of an electric circuit. A telescopic ladder 7, Fig. 1, is suspended from a trolley 2, which runs on a rail 1 fixed over the windows in front of a building. In case of fire in any part of a building, the nearest button 9 is pressed. This actuates an electromagnetic detent in one of the casings e, and allows a hinged flap to drop opposite the window. Another electromagnetic detent at f is also released, and the ladder trolley 2 is pulled along the rail by the weight 6 till it is stopped opposite the window by the dropped flap. The collision with the flap automatically brakes the trolley and releases the lower section of the ladder, the descent of which is retarded by an air brake. After use, the ladder and detents are re-set, the lower section of the ladder being wound up by a windlass 41 and rope 39.

Title: Improvements in Controlling Apparatus for Electric Motors
Inventor: KLINKENBERG JOHN
Filed: 1904-02-16
Granted: 1904-12-22
Abstract: 3840. Klinkenberg, J. Feb. 16. Lifts.-In a system for controlling motors, particularly suitable for lifts, one handle operates the switches for the field circuits, the armature circuits, the starting resistance, and brakes. The drawings show connections for a shunt-wound motor. The brake is of the known type shown, and the automatic resistance R is preferably that described in Specification No. 19,611, A.D. 1904. To start the lift the lever A is put in position B<1> the current then flows through leads P<1>, P<2> to magnet C, and, closing the switch C', current passes to the field magnets through leads P, P', P<4>, P<5>, M<1>, and thence through leads M<2>, M<3>, to the mains. When the switch C' closes, the brake is removed as the coil C<3> is excited through leads P, P<3> and P<6>. Similarly in the next position B<2>, the switch C<8> is closed and supplies current through leads P, P<3>, P<4>, P<8>, M<4>, and M<5>, and resistance R to the brushes E', E<2>. In the third position, the magnet C<9> is excited and the resistance R is gradually cut out. To stop the motor, the handle is turned back and the operations are reversed, but if the lift starts to drive the motor the handle is at once brought back to position B', and a switch D, coupled to switch C<8>, passes current generated by the motor to the braking-resistance D', which is automatically cut out as the current fails. The magnet F and resistance D' may be dispensed with, a switch being employed in connection with the resistance R. The brake is brought into action on bringing the arm A to the neutral position. The motor is reversed by reversing the handle A. In the first position switch C<8> releases the brake and excites the. fields, in the second, switch C" closes and supplies current to the brushes E<1>, E<2> in the reverse direction, and in the third position, the resistance R is slowly cut out.
