Granted: 1903-04-30
Abstract: 11,003. Preston, A. G., and Wild, R. May 13. Brakes.-The hand-levers of a brake for a wagon or other vehicle are connected by levers and rods or by racks and pinions which remove the handlever on one side from the rack or other retaining- device as the hand-lever on the other side is moved by the brakesman. Similar devices are described in Specifications Nos. 4716 and 5099, A.D. 1896. Fig. 3 shows a plan of one form of the invention. The hand-levers a are provided with staples l, which ride over the vertical bars k<1> connecting the levers k on the upper and lower ends of the spindles h. The levers k on one side move the lever i and the rod j<1>, which moves the levers i, k and the hand. lever a on the other side. If the hand-levers a are placed on the vehicle at corners diagonally opposite, the levers i are connected by two rods and a bell crank. The spindles h may be connected by a rod having at its ends racks which gear with sectors on the spindles.

Title: Improvements in and relating to Railway Frogs, Crossings Switches and the like.
Inventor: ERVIN GEORGE MCCLELLAN
Filed: 1902-09-26
Granted: 1903-03-19
Abstract: 21,002. Ervin, G. M. Sept. 26. Crossings; points and switches. - Relates to means for securing the wearing - plate or block in frogs, switches, switch mates, crossings, &c., whereby the removal for replacement is facilitated.

Patent GB-190301814-A (GB)
Title: Improvements in or relating to Pneumatic Hammers and like Percussive Tools.
Inventor: GREEN MARK HENRY
Filed: 1903-01-26
Granted: 1903-06-11
Abstract: 1814. Green, M. H. Jan. 26. Percussive hand tools.-Fig. 1 shows one form of the tool for chipping, caulking, &c., and Figs. 2 and 3 show modifications in which the valveshifting means are modified. An open-ended, tubular, annularly-ribbed valve g and a solid piston c with reduced parts all, a<111> are used in all cases. In the form shown in Fig. 1, compressed air reaches the rear of the cylinder through channels j, j<1>, j<11>, port 9, and holes 4, and the exhaust takes place through channels k<1>, k, space g<111>, and channel 11, always open to the atmosphere. The valve is moved forward by the difference of pressure upon the outer faces of the ribs 1, 3, live air, leaking into the space 10, acting on the rib 3, and the space 5, bounded by the rib 1, communicating with the passage e', open to the atmosphere by means of the channel g<11> and the neck a<111>. During the rear movement of the piston, live air reaches the front of the piston by means of channel j<11>, port 6, space g<111>, and channels k, k<1>. The exhaust takes place through holes 4 now opposite the channel 11. The valve is moved back to the position shown, by live air passing from the live-air channel m to the channel l across the neck a<11>. The channel communicates with the space 5. In the form shown in Fig. 2, the channels l, m, Fig. 1, are replaced by the channel p leading to the space 10 and the exhaust channel q perforating the cylinder. Channels p, q are intermittently connected by the neck a<11>, and act in the same way as the channels e', g<11> and neck a<111>, live air leaking into the spaces 5, 10. In the form shown in Fig. 3, the channels l, m, Fig. 1, are supplemented by channels r, v opening rearwardly into the space 10. A channel s<1> opens into the space 5 and into the cylinder at a point in the same transverse section as the channel s leading directly into the atmosphere through the cylinder wall. A live-air channel u communicates with the channel g<11> which, in this case, does not lead to the space 5. Thus the valve is shifted forwards by live air passing along channels u, g<11> and v, w to the space 10, and by means of exhaust channels s, s<1> leading to the space 5. The valve is shifted back again to the position shown by live air passing along the channels m, l to the space 5 and by means of the channel r, which communicates with the space 10 at t and with the exhaust through channels k, 11.

Title: Improvements in Steam Traps.
Inventor: MORGAN JOHN GRIFFITH
Filed: 1903-09-01
Granted: 1903-10-01
Abstract: 18,851. Morgan, J. G. Sept. 1. Steam traps.-The water of condensation passes through the hollow pivot C, arranged in the partition D', of a rocking vessel D, into the chamber D<3>, causing that chamber to fall against a set-screw G<1>. The steam inlet is by this movement closed, and the pipe F brought into communication with the discharge outlet in the pivot. When empty the vessel D is caused to rock back till it rests on the screw G by the counterweight E. The hollow pivot C is divided by a partition into a steam inlet C<2> and a water outlet C<3>, which have ports a, d communicating by corresponding ports and passages in the sleeve D' and partition D', with the top of the chamber D<3> and the pipe F respectively. The ports a, d are so arranged that when one is in register with its sleeve port the other is cut off. Stuffing-boxes H prevent leaking. Lateral shifting is prevented by screws I passing into grooves C' in the pivot.

Inventor: LEVI GIORGIO
Filed: 1904-06-18
Granted: 1905-04-20
Abstract: 13,875. Levi, G. June 18. Alkaline aluminates, carbonates, and hydrates; alumina.-Relates to the production or alkali and alumina from silicates such as leucite, sodalite, and nepheline. The mineral is digested under pressure with a solution of alkaline carbonate, or alkaline or alkaline earth hydrates. In an example, powdered leucite is heated with potash and water in an autoclave provided with a stirring- device. The product is filtered hot, and washed with potash and with water. The solution of potassium silicate thus obtained is treated by any known means to separate out the potash. The insoluble portion, consisting of alumina, silica, and impurities, such as iron, is treated with hot concentrated potash solution, or fused with solid potash; lime is then added to remove the silica, and, after again heating, the product is cooled and filtered. Alumina is obtained by known means from the filtrate, which consists of pure aluminate solution.
