Title: Improvement in Ploughs for Conduit Electric Railway Cars.
Inventor: GOTTSBERGER JAMES BANKER
Filed: 1900-06-19
Granted: 1900-08-11
Abstract: 11,120. Gottsberger, J. B. Jan. 4, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Electric railways on the conduit system. Collectors.-The ploughs are provided with two sets of shoes, so that the lower set can be dropped and the upper set brought into action when required. The shank A, of usual construction, is supported in guides C under the vehicle by catches O, which may be withdrawn by a connection P, in which case the springs a<1> depress the shank. The two sets of shoes B, B' are mounted by insulated washers on spring plates D, D', and are connected by fuzes &c. to the leads in the shank. The lower set are mounted on a block held to the shank by dowels h and by the head of the rod L lying between the plates M. When the collector is dropped, the rod is caught by stops R, and the weight of the appliance, aided by the springs a<1>, causes these plates M to bend and free the rod so that the lower part may be left behind. Arms L<1> on the rod L engage eye-bolts attached to the spring plates of the upper shoes B, and hold them inwardly until disengaged by the fall of the shank.

Title: Improvements in and relating to Reducing and like Fluid-pressure Valves.
Inventor: AULD JOHN
Filed: 1900-07-06
Granted: 1901-05-25
Abstract: 12,193. Auld, J. July 6. Pressure-regulating valves.-To increase the ratio of lip opening to area in a reducing or pressure regulating valve, a group of two or more small valves A, Fig. 1, are connected to a crosshead A<2>, which is linked to the rod D of a piston C fitted with a diaphragm C<1> and spring E, or otherwise balanced. Each small valve may have a separate balancing piston, and the arrangement may be adapted to double-beat valves. A reducing-valve for supplying a large volume of low-pressure steam is shown in Fig. 6. The low-pressure chamber X is connected by a pipe F<1> to a small valve F, which controls a pipe G through which steam passes from the high-pressure chamber Y to a cylinder a'. When the low-pressure steam falls below its minimum, the small valve opens and admits steam to the cylinder, so as to raise the piston a, and opens the main valve A. By an alternative arrangement indicated in dotted lines, the main valve is actuated by a piston H<2> underneath it. A modification applicable to single valves, double-beat valves, or groups of valves, has the small actuating-valve, but the piston and diaphragm arrangement are dispensed with. The operation of the small valve may be reversed, so that, when the low-pressure steam exceeds a certain pressure, the small valve opens, and admits steam to a piston which closes the reducing-valve. The Provisional Specification mentions the use of an annular valve in order to increase the ratio of opening to valve area.

Title: Improvement in Vapour Burning Lamps.
Inventor: MITCHELL WILLIS
Filed: 1900-10-04
Granted: 1901-02-23
Abstract: 17,618. Mitchell, W. May 17, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Vapour lamps. - The pressure in the reservoir A necessary to force the gasoline from the reservoir to the vaporizing- coil F is obtained in the first instance by means of the air pump B, and is maintained subsequently by the return to the reservoir through the pipe U of vapour generated in the coils F in excess of that consumed at the burner J. When starting the lamp, the air issuing from the outlet b of the air pump B impinges upon and agitates the gasoline, which thereupon gives off a certain amount of vapour. Upon opening the valve c<1>, this vapour traverses the pipe D, the channel e, and the coils F, and is ignited at the burner. The ends F<1> of the two coiled copper tubes F are attached to the upper ends of the U -shaped channeled piece E, and the other ends h<1> are connected to a channeled piece G, of which the outlet nozzle g<2> is controlled by a needle valve I. The bell-shaped depending baffle L, and the cylindrical casing H, H<1>, rapidly conduct from the flame sufficient heat to vaporize the gasoline supplied to the coils F by the pipe U, the filter R, S, and the channel e, and, when the valve I is opened, the vapour escaping to the mixing - tube K is superheated by traversing the narrow channels formed between the parts K, L, H<1> to the burner J. The air-supply holes x in the piece G may be closed by packing as shown at y, Fig. 1, and the chimney holder V is formed with a perforated partition U', air being admitted to the lower part of the holder by a hole u<4>, and to the upper part by holes u<3> to cool the chimney. The piece E is provided with a lug F<4> for supporting the mantle rod, the valve I is built up as shown in Figs. 10 to 13, and the filling-tube A' of the reservoir A is closed by the engagement of a projecting ring a on the stopper A' with packing in the groove a<1>.

Patent GB-190023842-A (GB)
Title: Improvements in or relating to Non-refillable Bottle or like Stoppers.
Inventor: BOULT ALFRED JULIUS
Filed: 1900-12-31
Granted: 1901-05-11
Abstract: 23,842. Boult, A. J., [Brisco, C. N.] Dec. 31. Stoppers; refilling, preventing. -Relates to improvements on the invention described in Specification No. 25,617, A.D. 1898, in which a disintegrable tablet or other mutable body is so acted on by the liquid, on an attempt at refilling the vessel, that it releases a spring-controlled valve, which then closes the neck. The present invention is intended to prevent the mutable body from being affected by any vapour remaining in the neck, or by the humidity of the air. The valve E', E, which normally closes the aperture h of the valve seat G, is made in two parts connected as shown by an angular pin and socket f<4>. The section E is detachably connected by the socket D, d to the valve-operating stem c, the sleeve D' fixed to the socket D telescoping with the sleeve D<2> fixed to the guard B. The disintegrable tablet l<2> is mounted between the spring arms l<1> of the holder H, and holds these arms in the socket d against the action of the spring l<3>. The tablet is enclosed in the chamber formed by the sleeves D<1>, D<2> and the parts E, c, and is thus protected from contact with the liquid in pouring out the liquid &c. The valve is raised, through the action of the cams n, by rotation the stem c to the left, and is returned to its seat, by projections on the socket d engaging the cams n', by rotating the stem to the right. When the valve is raised, the contents can be poured out through the passages p, a<5> and peripheral notches in the parts B', c. The upper surface of the guard B<1> is inclined, as shown, to direct any liquid remaining in the neck back to the ports a<5>. A packing-washer q forms a tight joint between the parts c, B', when they are in the normal position. If it is attempted to refill the vessel, the liquid flows down the central aperture in the guards B<1>, B, and through the apertures d' in the socket D, d into the chamber containing the tablet, which is thereupon dissolved and releases the valve. The section E<1> of the valve prevents liquid from being poured or forced into the vessel while the latter is tilted. In a modification, the tablet l<2> and its spring and holder are replaced by a plug of compressed sponge &c.

Abstract: 527. Boult, A. J., [Higgins, C. M.]. Jan. 8. Stoppers.-Relates to closures for bottles, jars, &c., and is more especially applicable to jars or bottles for containing adhesive pastes &c. The closure consists of an annular rim B, screwed, as shown, or otherwise secured on the neck of the vessel, and a cap or disc C, adapted to close the opening f in the rim B. A packing-washer i, placed in the recess h of the rim B, forms a tight joint with the mouth of the vessel, while the tapered flange m of the rim serves to remove any surplus adhesive from the brush. The cap or disc C fits tightly in the seat k formed in the rim B, and forms a liquid-tight closure therefor. The vessel can be opened by removing the entire closure, or, in case the rim B becomes stuck by the adhesive &c., by removing the part C only. In a modification, the part C is formed with two circumferential zones of slightly different diameters, the larger upper zone fitting the seat k tightly, while the smaller lower zone fits the seat loosely and is adapted for the temporary closing of the vessel. The part C can be removed conveniently by leverage exerted on its rim r.
