Title: Improvements in Mechanical Stokers for Furnaces.
Inventor: ROBERTS DAVID
Filed: 1903-05-22
Granted: 1904-03-03
Abstract: 11,732. Roberts, D. May 22. Mechanical stoking; grates.- Relates to mechanical stokers of the endless-chain grate type, and of the type wherein the bars move to and fro and the fuel is forced upon them by mechanical action. The grates are made in sections adapted to be independently operated at different speeds, in order that fresh fuel upon some sections may be brought quickly in between the mass of incandescent fuel on others. In the endless-chain grate shown in Fig. 1, mounted upon a frame c, and capable of being run into position upon the wheel d, the sections f, e are arranged alternately, and are mounted upon pulleys at the back which revolve on or with the shaft h. The front ends of the sections are carried on pulleys upon the shafts i, k, which may be rotated at various speeds by spur-wheels and eccentrics operated by the shaft n. When a sudden demand for steam arises, one set of sections may be made to travel faster and carry fresh fuel, which is fed on to it, through the door t, from hoppers s, between the incandescent fuel upon the other sections. The grate shown in Fig. 4 has reciprocating bars, which are mounted on rollers u<1>, the two sections being adapted to be operated by suitable mechanism attached to the shafts x, w, which may rotate at different speeds as in the previous case. Hoppers z feed fuel into casings y, which are provided with mechanism of ordinary construction, such as a link and eccentric, for actuating the fuel-forcing mechanism.

Abstract: 13.125. Rudge-Whitworth, Ltd., and Pugh, J. V. June 11. Securing wheels on axles; spokes.- A method for fixing wheels of motor cars &c. to their axles is shown in Fig. 28. The inner ends of the wooden spokes 3 meet and form a virtually - solid nave. They are gripped by the discs 1, 2, which have internal ribs engaging longitudinal grooves on the axle. Ribs 4 on the disc 1 engage radial grooves between the spokes. The disc 2 has face ratchet-teeth engaging similar teeth on the wooden spoke ends, which are preferably faced with metal. The parts are forced together by a nut on the axle, and, by rotating in opposite directions, are locked on the axle. Fig. 29 shows a modificition, in which the nut is dispensed with, the discs being held together by screw bolts 5, which pass through holes shaped to allow a slight relative rotation of the parts. Fig. 31 shows a modification in which the disc 1 has an internally-ribbed sleeve 6, fitting into a recess 7 in the disc 2. The ribs 4 on the disc 1 are dispensed with and the parts are tightened by means of the collar 8, bearing ratchet-teeth, and the nut i. Fig. 32 shows a method of fixing the hub of a wire-spoked wheel to the axle. A disc 10 having a ribbed sleeve 11 engaging grooves on the axle c, and provided with face ratchet-teeth, engages similar teeth at each end of the hub 9. The parts are tightened by a nut on the axle. Wheels thus fixed are interchangeable with wheels which rotate on their axles.

Granted: 1905-09-07
Abstract: 21,211. Kieseritzky, P. R. Oct. 3. Grant of Patent refused. Secondary batteries.-Negative plates of diminished capacity are regenerated, and new plates are prevented from decreasing in capacity, by immersing wood or the like, which has been treated with an alkaline fluid, in the electrolyte. Certain chemical compounds in the wood go into solution and prevent the plates from flaking. The prior treatment with alkali, such as caustic soda or potash ; sodium carbonate, or ammonia, removes certain injurious organic acids and resins from the woods. Slabs of treated wood may be placed between the positive and negative electrodes, between the cell wall and the electrodes, or in a perforated iron or lead pocket in the cell. Wood wool and shavings, or fibres of analogous organic substances, such as bamboo, reed, straw, turf, &c., may be compressed into slabs before or after treatment with alkali, and used in a similar manner.
