Title: Improvements relating to the Regulation of Dynamos.
Inventor: STRICKLAND FREDERIC
Filed: 1901-03-05
Granted: 1901-04-20
Abstract: 4695. Strickland, F. March 5. Dynamos, regulating.-Relates to the regulation of dynamos driven from shafts liable to variation of speed, e.g., dynamos employed for lighting trains and other vehicles and for ignition purposes in gas engines, petrol motors, and the like. The armature a is mounted on a sliding shaft b, driven by a friction clutch c, fast and loose pulleys, or like means, normally maintained in driving position by a spring d. When the electromotive force reaches a predetermined limit, the increase in the attractive force between the armature and the field magnet causes the shaft to be moved longitudinally so as to disengage the driving-gear. A nut g serves to adjust the force of the spring d. In cases where the dynamo is used in connection with secondary batteries, as in train lighting, the commutator is provided with an insulating-extension and with two pairs of brushes, one pair of which, viz., those connected to the secondary batteries, normally bear on the insulating-extension, and only come into contact with the commutator proper when the voltage exceeds a predetermined limit.

At the back bottom edge of the vehicle body 1 is placed a hopper 2, which leads into a chamber 12 passing up the back, along the top, down the front, and underneath the body. In this chamber a conveyer 4 is guided by pulleys 15, 16, 17, 18, and is operated either by hand from the wheel 31 or by the motion of the vehicle from the wheel axle or hub 10 and mechanism 9. The hopper is provided with a flap door 12<a>, and the rear of the body is formed with discharge doors 19. In order to dump sticky clay or the like from the buckets as they pass along the top, racks 50, Fig. 7, are secured to the cart, and the buckets are provided with pins which impinge on the teeth of the racks and so jog the buckets. For dealing with rags, straw, or the like, rakes may be placed between the buckets, or the edges of the buckets may be toothed. A ratchet arrangement may be interposed between the driving-mechanism 9 and the hand-wheel 31, whereby the latter may be rotated when the vehicle is at rest ; or a hand-operated clutch may be interposed between the wheel hub and the sprocket-wheel which drives the mechanism 9. In a modification, the buckets may travel in the reverse direction, or only along the back and top of the cart. The buckets may have ordinary means for keeping the loaded buckets normally upright, tipping them at a certain point, and returning them inverted to the hopper.

Title: Improvements in Gearing for Motor Cycles, Motor Cars and the like.
Inventor: CAREY ARTHUR BASIL
Filed: 1904-05-09
Granted: 1905-03-23
Abstract: 10,661. Carey, A. B. May 9. Motor cycles ; driving-mechanism ; brakes.-Relates to a three-speed epicyclic driving-gear for motor road d vehicles and motor cycles. In Fig. 1, the invention is shown applied to a shaft a driven by an engine directly or through a chain or like wheel i. Between toothed wheels b, b<1> of different diameters keyed to the shaft a is a loose sleeve c<1> bearing a driven sprocket c, or the like, and arms or discs d, carrying planet pinions e, e<1> meshing with the wheels b, b<1>. Loose wheels f, f<1> are provided with internally - toothed flanges f<2> in mesh with the pinions e, e', and with flanges f<3> on their outer sides internally coned to receive clutches h, h<1> sliding on the shaft a. The clutches h, h<1> are operated simultaneously by levers k or otherwise. The wheels f, f<1> may be gripped separately by band brakes g, g<1>. When the clutches are in engagement, the gear revolves as a whole, transmitting the highest speed, and the brakes may be used for braking. When the clutches and the brakes are disengaged, the motor runs free. When the brake on one side is applied, the epicyclic gearing on that side comes into action, a diminished speed being imparted to the bearings of the planet pinions and consequently to the driven sprocket c, the gearing on the other side running free. An application to the hub of a motor cycle or tri-car driving-wheel is shown in Fig. 2, where a hollow shaft a<x>, carrying the driven sprocket &c. i at one end, sliding clutches h<x> at both ends, and sun-wheels b of different diameters, one at each end, rides upon the usual fixed spindle j. Discs dx at the sides of the hub c<x>, which is recessed, carry planet pinions e meshing with teeth on inner flanges of loose wheels f, outer flanges f on which are gripped internally by expanding brakes g<x>. The invention may be applied to a hub in which a spindle revolves in external bearings, when the arrangement will be similar to that shown in Fig. 1, the discs d being larger and provided with flanges for spoke heads. The clutch h is in this case carried by rods passing horizontally through bosses on the chain-wheel i, the clutch h<1> being carried by similar rods passing through bosses on a chain - wheel arranged for pedalling on the other side of the hub.

Abstract: 14,730. Brier, H. June 30. Ice-making.-Relates to ice-making machines in which an eaeily-liquefiable gas, such as ammonia, is employed as the cooling-agent, and in which there is a receiver D, placed between the condenser or cooler B and the regulator E. A valve G is introduced in the pipe between a condenser and the receiver in order to maintain a higher pressure on the condenser side than on the receiver side, thus ensuring more efficient liquefaction of the cooling- agent in the condenser. One form of valve is shown in Fig. 2, consisting of an ordinary lift valve loaded with a spring. The condenser communicates with the opening g<3>, and the receiver with the opening g<4>. A dead weight or a weighted lever is sometimes employed in the place of a spring. A spring-loaded double-beat valve, Fig. 4, formed with its upper part of larger area than its lower part, may be used. In another form of valve, Fig. 5, the surface g<10> exposed to the condenser is of less area than the surface g<6> exposed to the receiver. The bottom of the valve communicates through the opening g<9> with the evaporator C. The liquefied gas passes through the holes g<8> in the valve.
