Granted: 1898-06-04
Abstract: 8739. Wikstr÷m, M. April 14. Horse clippers and the like.-Fig. 1 shows a treadledriving gear applied to driving shearing-appliances, the apparatus for converting the reciprocating movements of the treadle into rotary motion being strapped on the shearer's back. It may, however, be carried about the level of his shoulder, by a bracket or support resting on, or embedded in, the ground. The forward end of the treadle-lever rests on the ground, and near the latter is a foothold provided with a toe-strap. The rear end of the lever is connected to a strap L wrapped round a pulley G, Figs. 2 and 3. To one end of this pulley is attached a spring contained in a casing U, while the other is provided with a flange I, to which is secured a ring N by bolts 0, O. Ratchet levers Q, Q pivoted to this ring are forked at their inner ends to embrace studs R projecting from the flange I. Thus, when the pulley G is rotated in the direction of the arrow, Fig. 3, the pawls Q grip the flange M and rotate it and the flywheel and flexible shaft B. When the spring rotates the pulley in the other direction, the pawls move out of engagement with the flange M. For convenience of carriage, the treadle-lever may be made to fold in the middle.

Patent GB-189819033-A (GB)
Title: Improvements in Valve Gearing with Governor for Water-power Machinery.
Inventor: STUMPF JOHANN
Filed: 1898-09-06
Granted: 1899-09-06
Abstract: 19,033. Stumpf, J. Sept. 6. Governing or controlling pumps. -Relates to au arrangement of valves and valve gear, under the control of a governor, by which the power given out by a waterpressure engine is varied from the maximum to nil. The arrangement also allows the action of the engine to be reversed, so that it works as a pump, in which case it could be employed where large quantities of work are required to be absorbed by brake action. Fig. 1 shows the arrangement applied to an engine in which plungers a coupled by rods p drive a crank shank d. The pressure admission valves f open outwards from the plunger chambers e, and the exhaust valves g open inwards. Springs f<2>, g<2> tend to open the valves. The closing is regulated by the valve gearing, which consists of eccentrics F, G, rods k, h, bell-crank levers k<1>, h<1>, spring buffer rods k<2>, h<2>, and levers k<4>, h<4>, which act on the stems of the valves by means of arms k<5>, h<5>. The lever k' of the admission-valve gear is mounted on a bracket which is provided with plungers l working in small hydraulic cylinders l<1>, l<2>. The position of the plungers in the cylinders, and consequently the position of the bracket k<1> and the time of closing of the admission valves, are regulated by the governor R, which acts upon a piston slide valve m shown to a larger scale in Fig. 2, so as to admit pressure-water to one or other of the cylinders l<1>, l<2>. In full working, the admission valves are not closed till nearly the end of the stroke, but, if the gear comes into such a position as to cut-off at 75 of the stroke, the engine works for the rest of the stroke against the pressure, owing to the opening of the admission valves to the other plunger chamber, and the result is that only À5 of the full power is developed. Similarly, if the cut-off is made at half stroke no power is developed, and if at less than half-stroke the motor acts as a pump. A similar arrangement of gearing and governor is described as applied to a differential motor. A modified form of gearing regulated by hand is shown in Fig. 8 as applied to a differential motor, by means of which the direction of rotation may be reversed. Admission and exhaust valves are worked from one eccentric. The eccentric-rod k is suspended by a short link K from one arm of a bell-crank lever K<1>, the position of which can be regulated by a hand-lever o.

Patent GB-189826703-A (GB)
Title: Improvements in Primary Batteries.
Inventor: HARRISON HAYDN THIES
Filed: 1898-12-17
Granted: 1899-11-04
Abstract: 26,703. Harrison, H. T. Dec. 17. Primary batteries.-Relates to means for automatically feeding the electrolyte or depolarizer to the cells of primary batteries. The invention is shown in Fig. 1 as applied to cells B, each of which is made up of two porous cells D, each containing a carbon element F, and of a metal element F' placed between the cells D. The cells D are closed except where the pipes E for the supply of liquid enter them. The liquid is supplied through a valve H to a trough A divided by partitions C into as many compartments as there are cells B. The trough A is preferably slightly tilted, or the partitions C gradually diminish in height from the end where the liquid enters to the other end of the trough, in order that the cells may not be shortcircuited by conduction through the liquid. The gases evolved escape through a pipe J and a pressure-regulating trap or tank K. The supply valve H is kept open by the attraction of the solenoid I, which is operated by the battery current, and a shunt circuit is arranged which causes the valve H to be closed when the last compartment of the trough A is filled with liquid. This, as shown in Fig. 2, is effected by breaking the main circuit to the solenoid I at R by means of the electromagnet P, which comes into action when the liquid rises in the last compartment of the trough above the contact M so as to shunt the resistance O. Fig. 3 shows a modification of Fig. 2 in which a suitable number of turns or a separate winding T of the electromagnet P is connected in series with a resistance S and with the whole number of cells. When the electromotive force of the battery rises above a certain point, or the current discharge falls below a certain point, sufficient current flows to break the circuit at R, thus causing the valve H to be closed. The object is to economize electrolyte when secondary batteries are used in conjunc tion with the primary batteries. In the Provisional Specification is described a method of controlling the valve H by means of a float valve in the last compartment of the trough A.

Title: Improvements in Free-wheel Bicyles and other Velocipedes and in Brakes for the same.
Inventor: PUGH JOHN VERNON
Filed: 1899-09-18
Granted: 1900-07-28
Abstract: 18,799. Pugh, J. V. Sept. 18. Brakes ; clutches ; driving-mechanism.-A freewheel mechanism for bicycles and other velocipedes comprises two toothed rings d, e, having inclined teeth d', Fig. 3, and flanges d<2>. The ring d is fixed to the hub a of the back wheel, and the ring e is mounted loosely upon the spindle of the wheel. A chain-wheel f is provided with internal teeth engaging with the teeth of the rings d, e, and this chain-wheel is free to slide laterally, being kept in gear with the ring d while the rider is pedalling forwards ; at other times the chainwheel slides into gear with the ring e, and the rear wheel runs freely. The brake of the rear wheel is connected by a rod or other means to the arm i<2>, Fig. 2, of a ring i, carrying spring- pressed pawls k which engage with the teeth of a ratchet-wheel h, keyed to the ring e. By means of this arrangement, the brake is applied whenever the rider back-pedals. In a modification, the ring corresponding to the ring e is formed with radial projections, instead of a flange, which engage with inclined slots in the flange of a fixed disc. The ends of the inclined slots are enlarged, and receive the ends of a number of yielding and radial arms forming parts of a disc arranged between the ring and the flanged disc previously described. By these arrangements, the ring is capable of rotating through a small angle, if necessary, to bring the teeth of the rings into register, and allow the chain-wheel to pass from one ring to the other. When the rider backpedals, the ring corresponding to the ring e, Fig. 1, moves laterally and bears against the lock-nut by which the other ring is fixed to the hub, and the cycle is retarded, or brought to rest.

Abstract: 14,136. Murphy, E. E. Aug. 7. AÙrating liquids. -Relates to apparatus for carbonating water and other liquids, and consists in providing an apparatus in which the carbonating operation is controlled directly by the accumulation of the carbonated liquid, the carbonation automatically ceasing when a predetermined quantity has been accumulated, and automatically starting when the accumulation has been reduced. The apparatus consists of a storage chamber A with a draw-off pipe B controlled by a valve B<5>. The chamber A is supplied with aÙrated liquid which has been formed by mingling gas and water in the mixing-chamber G. The gas enters through the passage O<1> past a spring valve O<2>, and the water enters through a pipe N, strainer L, and spray-producer J. The chamber G is filled with metallic sponge. Any gas which escapes from the liquid in the storage chamber passes up the passage G<6> and becomes mixed with the inflowing fresh water. The reduction of pressure caused by drawing-off liquid from the chamber A causes the valve O<2> to be opened and a fresh supply of gas to be admitted, while the increase of pressure caused by the accumulation of aerated liquid in the apparatus closes the valve O<2>, and thus shuts off the supply of gas.
