Title: Improved Device for Moving a Driving Belt from a Fast to a Loose Pulley.
Inventor: GARLICK EDGAR
Filed: 1903-12-03
Granted: 1904-10-27
Abstract: 26,413. Garlick, E., and Parkin, J. Dec. 3. Actuating valves and cocks.-Relates to a belt shifter which is caused to move a belt from one pulley to another by closing an electric circuit by means of pressing a button &c., but which may be used to turn off the lever of a steam cock. A weight D, Fig. 1, is suspended by a cord wound around a barrel B, which is fitted with a pulley E and spur-wheel F, the latter gearing with a pinion G on a partly-threaded shaft H. A ratchet I, Figs. 1 and 2, on the shaft H is held by a pawl J, secured to the same shaft K as a lever L which rests on a lever M. On completing the circuit through an electromagnet Q, the armature P supporting the cranked end 0 of a pivoted hammer N is drawn within the coil, and the hammer, in falling, strikes the lever M, releasing the pawl J from the ratchet I. The weight D descends and the shaft H is rotated, the threaded portion driving along a nut to which is attached links S secured to the belt forks T. To stop the fall of the weight, the pulley E is provided with a brake, which is normally held out of action by a spring V but which is actuated by the nut striking the lever W. The nut may be used for actuating other stopping-mechanism, such as to turn the lever of a steam cock &c. According to the Provisional Specification, the weight and nut can be brought back by means of a handle, shown in Fig. 1, and instead of the spur-wheels F, G, a chain and chain-wheels may be employed. A spring-actuated barrel may also be used instead of a barrel and weight.

Title: Improvements in the Manufacture of Bottles for use with Screw Sealing Caps.
Inventor: NASH RICHARD GRAINGER
Filed: 1904-05-12
Granted: 1905-03-16
Abstract: 11,005. Nash, R. G. May 12. Bottle necks. - In the manufacture of bottles for use with screw-cap stoppers, the threaded portion of the bottle neck is tapered as regards the diameter at the apices of the threads, while the diameter at the root of the threads remains constant. The amount of taper may correspond with the depth of the screw threads, so that the thread dies out towards the mouth of the bottle, which is formed with a round lip b. In this way, the usual feather edges due to the abrupt termination of the screw threads are avoided, and the round lip on the bottle facilitates the application of the stopper, and also, due to the reduced area of the lip in contact with the lining of the stopper, forms a tight joint.

Granted: 1906-09-26
Abstract: 19,428. Dargie, J. Sept. 26. Torches. - At the instant of lighting a street or other lamp, an elongated flame is projected through the opening l by the ignition by the permanent flame of a lamp c of a blast of air-gas delivered from a pipe a. The airgas is supplied by forcing air .by means of a pump e<1> and a tube f through a carburettor d. The absorbent material in the upper two of the three chambers into which the carburettor is divided by perfoforated partitions h is saturated with spirit supplied through a tube, and the surplus spirit is drawn off through a cock i. Under the control of a cock k, the air-gas ascends the pipe S<11> to the supply pipe a, a valve m shortening the emission of gas and rendering it unnecessary to turn off the cock k while passing from lamp to lamp. The opening l may be closed by a sliding bar n, and the removable tube j is retained in position by a catch o. In a modification intended for use in churches and other buildings, methylated spirit is burned in the lamp c, and a key is fixed on the top of the tube j for operating the gas cocks.

Title: Improvements relating to coin-freed Gas Meters.
Filed: 1906-01-06
Granted: 1906-08-23
Abstract: 438. Durnberg & Co., M., and Olthoff, H. Jan. 6. Ball and float valves; liquidseal valves.-In wet gas-meters, a bell-crank k is rocked, on prepayment, thereby lowering a vessel i containing water away from the end of a pipe c, and thus permitting the passage of gas through the pipe from the chamber a. The consequent reduction of pressure causes the float valve, which consists of a body w attached to the float y and a seating v, to rise, permitting the free passage of the gas. When the quantity of gas paid for is nearly exhausted, the registering - mechanism causes the bell-crank k to be rocked in the reverse direction, thereby raising, the vessel i, which preferably carries a cone r, the latter entering, the vessel c and gradually cutting off the passage of the gas. The pressure in the chamber a is thus increased, causing the valve seating v to be depressed and finally the valve body w, for completely cutting off the supply.
