Title: Improvements in Switches for Electric Motors.
Inventor: TURNER HENRY HERBERT
Filed: 1897-10-29
Granted: 1898-10-01
Abstract: 25,061. Turner, H. H., Turner, A., Turner, A., and Aveyard, G. S. Oct. 29. Switches for motors are so arranged that the shunt or field circuit is first made and then the armature circuit, the resistances being slowly cut out. Fig. 1 shows the arrangement. A long arm A is pivoted at A' to a nut or contact B mounted on a finelythreaded screw C. The free end A' of the arm A is hooked to engage with the main switch arm F which is coupled with the shunt switch arms. The nut B carries the armature contacts, which rub over the resistance contacts M. On operating the handle N, the main and shunt switches are first operated, and finally the armature circuit closed, the hook A<2> leaving the arm F. On reversing the handle the resistances are first put in, and then the armature and shunt are both shut off by the point of A' engaging the end of the arm F, springs 0, O<1> giving a quick break. A bracket Q serves as a guide and support for the arm A. A glass cover may be arranged over the main switch for use in emergencies.

Granted: 1899-11-11
Abstract: 24,759. Renard, D. A. Nov. 23. Motor road vehicles.-Relates to variable-speed driving-mechanism for cycles, motor cycles, motor cars, &c. The invention is shown as applied to a bicycle. The crank axle A carries a disc C with two or more rings of conical, hemispherical, &c. teeth c', c<2> with which a pinion F on a longitudinal shaft E may be caused to gear. A similar pinion G is carried on the rear end of the shaft E, and may be caused to gear with rings of teeth d', d<2> on a disc D fixed to the driving-wheel hub. The pinions F, G slide on keyways on the shaft, and may be actuated independently, giving four speeds, or simultaneously, as shown, giving two speeds, by suitable levers H, h. The discs C, D may be supported by a roller as shown at I. The conical &c. teeth may be replaced by pinions as shown in Fig. 3. In this case a sliding clutch k serves to lock either pinion to the axle. The disc C may be enclosed in a casing forming a gear case, and the shaft E may pass through the tubular stay L, Fig. 3. Fig. 4 shows forms of gear-wheels used with a double pinion sliding on the shaft. In the case of motor vehicles, the shaft E may be lengthened so that the pinions can gear with the teeth on the opposite side of the axle so as to reverse the motion.

Title: Improvements in Twill Motions of Card Setting Machines.
Inventor: BLACKBURN ABEL
Filed: 1899-05-02
Granted: 1900-04-14
Abstract: 9201. Blackburn, A., and Tetlow, J. R. May 2. Cards, wire.-Relates to card-setting machines. The ratchet-wheel D of the twill cam is actuated intermittently by a spring lever B, which is mounted on the boss of the ratchet-wheel, is operated by a cam F, and is regulated by a screw L. The end of the lever B which is engaged by the cam F is provided with a sliding spring bolt E having a projecting part E' which engages at the proper times with the cam F, the spring bolt E being moved longitudinally in one direction by a bevelled projection on a lever H carried by the reversing-shaft J, and in the other by its spring. The reversal of the shaft J causes the projection E' to pass through a gap in the flange of the cam F, where it is held until the cam and flange have rotated sufficiently to prevent the return of the bolt E until a complete rotation of the cam has been effected. The twill cam is mounted on the carriage, and has upon its face a cam surface which is pressed by springs against a stud projecting from a shell or frame surrounding the carriage screw. In order to avoid back-lash, the screw engages with two threaded sleeves or bushes, one of which is fixed to the frame or shell and the other is connected to the first by springs.

Title: Improvements in or relating to the Tanning and Treatment of Leather and Skins.
Inventor: BOULT ALFRED JULIUS
Filed: 1899-06-29
Granted: 1900-06-29
Abstract: 13,532. Boult, A. J., [Prost, P. A. D., and Godard, A.]. June 29. Tanning; hides and skins, tanned, treating.-The de-haired skins are treated with a solution of a metallic salt which opens the pores of the skin and partially tans it. The skins, when nearly dry, are rendered pliable by rolling &c., and are then immersed in a solution of a salt which will combine with and fix the salt previously deposited and so complete the tanning. The solution employed for the first bath may be sodium sulphate, or, preferably, chloride of sodium together with sulphuric acid. A proportion of tanning or other liquor, or new or spent bark, may be added to this bath to give colour to the skins. The second or fixing bath contains barium chloride or nitrate, a precipitate of barium sulphate being thus formed in the skin tissue. Tanning or colouring liquor may be added to this bath. When mineral tanning is employed, the first bath contains a chromium compound such as potassium bichromate iu addition to the sodium chloride and sulphuric acid, and in the second bath a portion of the barium salt may be replaced by sodium hyposulphite. Leather to be employed for belting, harness, soles, &c., is treated as above described, and is then caused to absorb copaline, tar, resin, &c. in alcoholic solution, with or without wax or other fatty or greasy substances. Sole leather may be tanned by known processes, dried, and roughened on a gripper to open the pores. It is then saturated with a solution containing gelatine, chromic acid or potassium bichromate, and glycerine or molasses. Subsequent exposure to light and air transforms the chromium into oxide, which renders the gelatine insoluble.
