Title: Improvements in Electricity Meters.
Filed: 1899-09-13
Granted: 1900-09-01
Abstract: 18,468. Chamberlain & Hookham and Holden, S. H. Sept. 13. Drawings to . Specification. Thermo-electric batteries.-Thermo-couples consisting of thick bismuth and antimony rods, joined end to end, are used to furnish currents in electric motor meters, the junctions being heated by surrounding coils of wire conveying the currents to be measured, or constant shunt currents. In one form, three such couples radiate from a bismuth block, the antimony ends being connected by flexible metal strips, to furnish a large current to a meter armature. In other forms, the thermoelectric currents are employed to correct errors at certain speeds of the meters.

Abstract: 24,218. Lake, H. H., [Freeman, A.]. Dec. 5. TuyÞres.-Relates to air-supplying apparatus, for use more particularly with locomotive fireboxes, but applicable also in connection with stationary and other furnaces. Below the usual brick arch 5, Fig. 5, which has an opening 7 at its forward end, is a series of tuyÞres through which air, previously heated in coils arranged on each side of the smoke box, is delivered. Above the firehole door is another series of tuyÞres. Fig. 6. The lower tuyÞres comprise a series of air tubes 16 communicating with a transverse pipe or manifold 13, into which steam jets may be delivered to induce a current of air. Round each of the tubes 16 is a water casing 17, of elongated oval section, in communication with the water space of the boiler. The upper tuyeres are constructed and attached as shown in Fig. 6. They are loosely hung on hook-ended stays 28, and are supplied with air through tubes 25. Either series of tuyÞres may be used alone, and the arch 5 may be dispensed with.

Granted: 1900-04-14
Abstract: 2347. Haddan, H. J., [Hartmann & Braun]. Feb. 6. Toothed gearing.-Relates to two-speed gear for cycles &c., arranged to give free pedals when the low-speed gear is in action. The spur-wheel a is connected by a feather and key-way to the crankaxle h, and is movable on it, so that a clutch on its boss engages the spur-wheel d, loose on the axle but fixed to the chain-wheel r or its equivalent. The wheels a and d gear with spur-wheels b, c, mounted on a countershaft. The wheel b is loose, but carries a pawl engaging a ratchetwheel fixed on the axle. The pawl and ratchet allow the chain-wheel to over-run the crank-axle when the gear is in the position shown. The spur-wheel a is moved to change the gear by an eccentric rod u or other mechanism. The clutch may be made separate from the wheel a, both spurwheels a and d being loose on the axle. A roller clutch can be used instead of the ratchet and pawl.

Granted: 1901-08-17
Abstract: 18,034. Sellner, L. Oct. 10. Drawings to Specification. Signals, electric-lamp, colour, and flash.-The five distinctive colour signals, viz., continuous white, continuous red, intermittent white, intermittent red, and alternate white and red, employed in the lamp signalling-system described in Specification No. 19,826, A.D. 1895, are employed in the present invention as the fundamental signals for signalling by the morse or other suitable code. For example, in the morse code, the continuous white light may represent a dot, the continuous red a dash, the intermittent white the space between letters, the intermittent red the space between two words, and the alternate white and red the beginning and end of the signal. A single lantern adapted to produce these five signals is employed, and is connected in known arrangement to a switchboard, the lever of which can be moved as required to one or other of the corresponding five operative positions. The switch apparatus may be marked with the signalling-code, and may register, by suitable known means, the signals transmitted. The colours are not restricted to red and white.

Abstract: 19,576. Lake, H. H., [Soc. I. Reynet et Cie.]. Oct. 1. Signals on engines &c. ; stopping engines &c. i n d i - cators and repeaters, signal; indicating and recording movements of trains; recording signals. - Relates t o apparatus by which a whistle is automatically sounded on a locomotive, and the compressed - air brakes are applied, when a ' danger' signal is passed, and comprises also a speed indicator and a registering-mechanism, which records the distance by which the locomotive passes the signal, the speed at which the signal was passed, and the time during which the driver leaves the whistle in action before resetting the apparatus. The curved bar a, pivoted at b between the rails, is lowered and inoperative when the ordinary signal is at 'line 'clear,' but is raised to the operative position, as shown, by the cam c connected to the signaloperating mechanism, when the signal is put to 'danger.' In its operative position, the bar is adapted to engage the spring-controlled cushioning- roller k and a second roller m on the lever i mounted on the engine, the movement of this lever drawing down the rods o, s, the latter of which opens an alarm steam whistle t, and a cock u in a conduit v of the brake system. The conduit v is fitted with a cock adapted to regulate the supply, the handle of this cock being retained so that it cannot be operated by the driver. The rod o, when lowered, is secured against the lifting action of the spring p and counterweight q, by a pawl r, which is released by the driver to re-set the apparatus. The recording - mechanism is enclosed in a box y, the records being made on a paper strip a<1>. which is marked for time and distance and is driven by clockwork. During the time that the rod o remains lowered, a stylus b<1> is held in contact with the strip a' by the levers x, c'. The speed is recorded on the strip by a punch d<1>, which is operated through the pawl e<1> by the teeth of the ratchet-wheel f<1>. The ratchetwheel is rotated by the lever pawl l<1>, which is operated through the connections k<1>, i<1> from the spring tappet g' actuated by the crosshead z. Other types of speed-registering mechanism may be used.

Abstract: 244. Steenkiste, A. van. Jan. 3. Retting; lubricating fibres; processes.-The flax, hemp, ramie, &c. is placed in an openwork or skeleton basket o, which is divided into compartments and can be run on rails m into a skeleton or openwork drum j, which can rotate on rollers within a boiler or digester a having a perforated bottom p, beneath which are hot-water and steam pipes r. The material is first subjected for an hour to the action of steam and water at 100‹ C., and afterwards to a second treatment for an hour, during which the pressure of the steam is raised to three atmospheres. After the second operation, about 3 per cent. of glycerine, or sulpho-ricinate of soda &c. may be added to the bath to render the material supple. When treating the coarser kinds of fibre, the second operation may be repeated. One end of the digester is hinged, to allow of the insertion and removal of the basket o ; and throughout the operation the basket o and drum i are intermittently rotated at intervals of ten minutes by means of the belt gearing shown in Fig. 1. A pair of ropes t passing over loose grooved pulleys q are connected at intervals by one or more bands or straps u, which rotate intermittently a fast pulley s between the pulleys q on the shaft of the basket and drum.
