Patent GB-190107617-A (GB)
Title: Improvements in Electric Meters.
Inventor: VAUGHAN-SHERRIN JOHN
Filed: 1901-04-13
Granted: 1902-06-13
Abstract: 7617. Vaughan-Sherrin, J. April 13. Electricity, supplying, in general.-An electrolytic meter has a cell a containing fixed and movable electrodes of copper, zinc, or other metal, in copper sulphate solution or other electrolyte, through which the whole current is passed by a reversing switch k, so that the movable electrode alternately increases and decreases in weight. The movable electrode is hung from a rocking beam c, balanced by an adjustable weight d. The beam c carries a mercury cup and a pin to make contacts with a stationary pin g and cup r in its extreme positions ; a current is thus supplied to either of two electromagnets j, s, which act on armatures to throw the mercury cup switch k, and reverse the current through the cell a. The contacts and cups are preferably arranged so that the main circuit is not broken during the reversal. A counter, operated by a ratchet-and-pawl connection with the switch k, may register the number of reversals, and the quantity supplied. Cups n<5>, p<5>, and contacts on the switch k, open the circuit of either electromagnet j, s after it has effected a reversal. A disclaimer refers to Specifications No. 4762, A.D. 1878, and No. 4391, A.D. 1880, [Abridgment Class Electricity, Measuring &c.]. The Provisional Specification mentions modifications in which both the electrodes are carried by beams movable on one fulcrum, or both electrodes may be stationary and the cell suspended from the beam. Coin action; coin-discharging mechanism.-The coin falls from an inclined shoot upon a counterweighted switch (not shown), depressing this into mercury cups to close the supply circuit. The coin is displaced by an arm of the reversing switch k, when the equivalent quantity has been supplied, and the supply switch then falls back, opening the circuit. The Provisional Specification describes a modified arrangement, in which the coin falls from the shoot into a helical groove in a wheel driven from the counting-mechanism.

Patent GB-190319439-A (GB)
Title: Improvements in Hydraulic Presses.
Filed: 1903-09-09
Granted: 1904-07-14
Abstract: 19,439. Davy Bros., and Crowe, E. Sept. 9. Testing armour plates.-The valves of hydraulic presses of the kind described in Specification No. 24,537, A.D. 1902, used in testing armour plates, are controlled by hand so that the descent of the press-head can be readily regulated. A press is shown in which the pumps P communicate with the press cylinder A by the pipe a and with the lifting-cylinders C by the pipes c, c'. By the arrangement of valves shown, the pressure can be applied to the cylinder A for the working stroke, or to the cylinders C for the return stroke ; or the main and lifting cylinders can be connected at the same time with the exhaust, or with each other and the exhaust, so that the press-head may descend under its own weight. The high-pressure distribution valve E controls the communication of the pumps and also of the cylinders C with the cylinder A, the pumps being always in communication with the cylinders C through the bye-pass M and the screw-down valve N, so that, by regulating the opening of the latter valve, the movement of the ram B can be slowed or stopped. The valve G allows water to flow from the exhaust J to the cylinder A when the ram B is descending the idle part of the stroke. The exhaust valve F has a number of orifices k<1> leading from the annular space f around the valve to the space k above the valve. The body of the valve F is of two diameters, the portion above the annular passage f being of larger diameter than that forming the inner wall of this passage. The orifice of the pilot valve K is greater than the total area of the passage k<1>, so that water can escape from the space k more quickly than it can enter, with the result that, as the pilot valve K is raised, the pressure from the main cylinder acting in the passage f will raise the valve F until the area of the orifice of the valve K is equal to the collective area of the orifices k<1>, the valve F being thus made to follow the motions of the valve K. The exhaust valve F and the highpressure distribution valve E are controlled by a hand-lever L and, by the introduction of a pin-andslot mechanism in the connection to the valve E, the valve F is raised slightly before the valve E commences to close, in order to relieve the pressure on the latter.

Ironing-machines.- Machines for ironing, smoothing, or glossing linen &c., are provided with guards which are automatically brought into operation when the work is being fed to the machine in order to prevent the operators from being injured. The articles to be ironed are fed between a roller a, Fig. 1, and an iron or bed b by means of a bar c pivoted at c<1> to the bed b. The guard-plate d is connected to a tube d' carried by links e, e<1>, which are mounted respectively on studs f fixed to the frame of the machine, and on studs e<2> attached to the bar c. When the hinged bar c is moved, by means of a rod c' operated by a foot-lever, to the position shown by the dotted lines in Fig. 1, in order that the articles may be introduced between the roller a and bed b, the guard d is moved by means of the links e, e<1> into such a position that it prevents the hands of the operator from coming into contact with the roller a. The ends e<3> of the links e are bifurcated to allow the links to be removed during cleaning operations. In modifications of the invention, shown in Figs. 5 and 7, the links e are dispensed with, and bowls h are mounted upon the tube d'. The bowls h are supported and guided by inclined surfaces g<1> of brackets g fixed to the frame A. As shown in Fig. 5, the brackets g are adjustably connected to brackets k fixed to the frame A. As shown in Fig. 7, the brackets g are open in front, and allow of the displacement of the plate d. The plate d may be operated independently of the bar c. The actuating- mechanism may be replaced by cams, cranks, &c.

Abstract: 11,972. Taylor, R. May 26. Syringes.-Relates to a device for filling bottles, or for injecting liquids under pressure, and is specially applicable for directing a jet of fluid in surgical operations, for instance in cleansing a wound. The part of the device which carries the nozzle, or outlet, is adapted to be moved axially relatively to the body part, whereby a spring-controlled valve is opened. In the form shown in Fig. 1, a nozzle j, formed with a flange j<1> adapted to rest on the mouth k of the vessel to be filled, is adapted to slide on a tube d d connected through a reservoir a and a pipe b to a liquid supply. The nozzle j is connected by a wire m to a spring- controlled slide valve g, which closes an opening in the pipe d. In a modification, a tubular valve may be used instead of the slide valve. In some cases, the chamber a may be made sufficiently large to contain the desired amount of liquid, the tube b being dispensed with. Or, the chamber may consist simply of a conical funnel, when the device is to be used for filling bottles and it is desired to cut off the liquid supply suddenly. In the form shown in Fig. 3, the chamber a is provided with a jacket o of rubber or other resilient material. The chamber is closed by a plug c and the rubber jacket by a plug p, and a spring-controller valve is connected by a pin q to the plug p. The valve is opened by the pressure of the hand, or the mouth of a vessel, against the plug p. In Fig. 5, the device is shown provided with an india-rubber valve v adapted to be opened by pressing upwards the collar j<1> of the nozzle d. In the arrangement shown in Fig. 6, a fiexible tube 5 is normally closed by a pinch-cock 4. The pinching-members are held in their closed position by a rubber band 6, and are moved apart, when required, by pivoted levers 3, 7 operated by sliding the nozzlej. Two of any of the above-described types of injectors and bottle fillers may be combined in one apparatus, for instance to supply a mixture of oxygen and hydrogen or of hot and cold water. The valves may be operated independently, and both outlets may unite in one nozzle.

Title: Electrical Locomotive
Inventor: FAIRWEATHER WALLACE
Filed: 1904-06-14
Granted: 1904-07-14
Abstract: 13,428. Fairweather, W., [Brown Hoisting Machine Co.]. June 14. Electric locomotives.-Relates to means for preventing the motor-driven wheels of electric locomotives suspended from a single rail from gripping the sides of the rail when rounding curves. Figs. 1 and 3 show the elevation and plan of an electric locomotive suspended from the I rail A by the wheels B, B', C, C' which are driven by the motors D, D', E, E<1>. The wheels and motors are mounted in pairs upon the frames F, F<1>, which are connected to the under part of the locomotive by swivel connections P, P<1>. The frames F, F<1> have projecting arms L, L' which are connected to one another at p by a bolt working in slots formed in them. The motors are driven at equal speeds, and, consequently, when rounding curves, there is a tendency for each pair of wheels to twist out of a radial direction and grip the rail, but, as the forces thereby exerted at the bolt p are in opposite directions, no such twisting can occur, and the locomotive passes smoothly round the curve. Any number of pairs of wheels may be similarly linked. The trolley wire and trolleys are shown at w, t, t<1>, respectively.
