Granted: 1900-03-31
Abstract: 11,204. Bond, E. S., and Lee, C. May 30. Gas or explosive-vapour engines.-The combustion chamber is spherical-ended, carries the admission and exhaust valve-chests, and is bolted to the cylinder. The exhaust passage is as straight and as near the cylinder as possible. The carburetting-apparatus, Fig. 5, is suppoited on a trunnion and balanced by a pendulum, so that, when used on motor cars, it may always remain level to enable the valve 19, which is operated by a float in the vessel 20, to close with precision ; the pipe connections 21, 22 are consequently flexible. The governor removes the bowl 35 on the exhaust valve rod 36 out of the path of its cam 34 when the speed is excessive, but presses it against the lever 47 of a supplementary exhaust valve, which is held open till the speed falls. The Provisional Specification states that the cam 34 is employed to close the exhaust valve, and fails to do so when the speed is excessive.

Patent GB-190110302-A (GB)
Title: Improvements in Typewriting Machines.
Inventor: FELL JOHN CORRY
Filed: 1901-05-17
Granted: 1901-06-22
Abstract: 10,302. Fell, J. C., [Union Typewriter Co.]. May 17. Type-writers.-In front-strike and like machines in which the type-bars are packed very closely in the basket, there is a tendency for collision to occur when adjacent bars are operated successively at high speed. To prevent this the order of the type-bars is re-arranged, without varying the order of the keys in the keyboard, cross-connections being employed for that purpose. The re-arrangement is such that adjacent type-bars will rarely be operated successively. In Fig. 6 the lower line shows the order of the characters on the standard keyboard, and the upper line the improved order of the type-bars. The re-arrangement takes place by cross-connections between adjacent keys and typebars. Thus E and X are cross-connected to separate the type-bar E from the type-bar D. Fig. 1 shows a machine of the kind described in Specification No. 15,643, A.D. 1900, with the present improvement applied thereto. The adjacent bellcrank levers 23, 25, which transmit movement to the type-bars, are formed with offsets and curves, shown also in Fig. 5, so as to reverse the order of the type-bars. In the modification shown in Fig. 7, the key levers 28 are made to cross one another, the levers 22 being of the usual form. In another modification, the links 21, Fig. 1, which connect the levers 23 &c. with the type-bars 14, are crossed. Fig. 11 shows a modification in which the type-bar 40, the hub of which is nearest the observer, is arched and bent so as to bring the type to the further side of the bar 39, thus reversing the order of the bars with respect to the links 21. The same result may be obtained by the device shown in Fig. 17. The type-bars are arranged in pairs 44, 46, provided with hubs 42, 48 pivoted in hangers carried by a segmental plate. The link which actuates the bar 44 is connected to the lug 45, which is in the same plane as the bar, but the link which actuates the bar 46 is connected at 50 to a curved arm 49 carried at the further end of the hub 48, the links being thus in reverse order to the bars. In a further modification, the key levers are directly connected by crossed links to the type-bar hubs.

Title: Process for Preparing Cobalt Hydroxide or a Cobalt Ammonium Salt, the Process being applicable for Separating Cobalt from Nickel, Copper and other Metals.
Inventor: FRASCH HANS ALBERT
Filed: 1901-09-24
Granted: 1902-05-08
Abstract: 19,038. Frasch, H. A. Sept. 24. Cobalt hydrates, oxides, and salts.-Metallic solutions or a mixture of oxides containing cobalt are treated with ammonia until all the soluble hydrates, such as cobalt, nickel, copper, and zinc, are in solution. The nickel and cobalt are then precipitated as double chlorides with ammonia, by means of brine or any suitable salt. This method is described in Specification No. 284, A.D. 1901, for precipitating nickel - ammonium chloride alone. The mixed salts, after washing with ammoniated brine, are treated with water, whereby the nickel salt goes into solution, while the cobalt-ammonium chloride is decomposed, the hydrate being deposited. The latter may be again dissolved in ammonia, and re-precipitated as the double salt with ammonia by means of brine. The formula of the salt is:-Co(NH3)2Cl2+4NH3. The processes may be adopted for separating cobalt from nickel, copper, and other metals. A solution of the double salt in ammonia may be used as a plating-solution.

Patent GB-190228612-A (GB)
Title: Improvements in, and relating to, Brake Mechanism applicable to Cycles, Motor Cars, & other Road Vehicles
Inventor: BENNETT GEORGE EDWIN
Filed: 1902-12-27
Granted: 1903-12-24
Abstract: 28,612. Bennett, G. E. Dec. 27. Brakes.-Relates to brake mechanism of the type described in Specification No. 7673, A.D. 1901, applicable for cycles, and other vehicles. The hand-lever acts through ratchet-and-pawl mechanism and equalizing-levers, whereby the brakes may be held on without strain upon the hands of the operator, the pressure may be increased when desired, and the pull on the two brakes equalized. The invention also comprises a stop or abutment for use in connection with the Bowden-wire transmission, and an arrangement by which the pressure of the foot may be exerted on the brake mechanism in cases of emergency. As applied to a bicycle, the front and rear brake connections b, c are attached to a lever d adjustably-pivoted to a sector lever a provided with teeth e. A hand-lever j, center like the lever a, on the stud f, has a spring-controlled pawl k engaging the teeth, while a cheek pawl m is pivoted on the clip g. On lifting the hand-lever j to apply the brakes, the pawl k raises the lever a, the pawl m sliding over the teeth. On releasing the hand-lever, it drops to its normal position, but the lever a is retained uplifted by the pawl m, so that the brakes are still kept on. To remove the brakes, the lever j is pressed down, when the pawl k engages the projection o of the pawl m and is so freed from the teeth, while further depression brings the handlever into contact with the arm p of the pawl m, which is consequently disengaged from the teeth on the lever a, and the brakes may return to their normal position. In a modification, Fig. 3, a socket-piece r provided with a bracket s, on which a cranked hand-lever and the lever a are fulcrummed, is fixed in either end of the handle-bar i. The operation is practically the same as with the first arrangement. In another form, Fig. 5, two bell-crank or other levers u connected by a link v are pivoted by the studs t on the lever j ; in Fig. 7 this arrangement is shown in conjunction with the ratchet device shown in Fig. 3. Both of the levers u may be fulcrummed on one stud, and each of the arrangements may be adapted to be operated by the foot. When a bell-crank or other lever forms a part of the rear brake connection a projecting arm is provided for the operation of this lever by the foot. In an abutment device for flexible connections, such as in the Bowden mechanism, a swivelling guide-tube y, Fig. 10, abuts against a stop z formed by an extension of the clip g. The end of the outer member 1 of the connection abuts inside one end of the tube, while the nipple 2 to which the inner member 3 is fixed may slide in the other end. To form the swivelling point, an adjustable ball supported by the stop z, screws on to the tube y.
