Title: A New Race Game
Inventor: CLANNER STEFAN VON
Filed: 1902-11-07
Granted: 1903-10-29
Abstract: 24,441. Clanner, S. von, and JÚkey, C. von. Nov. 7. Race games.-Relates to a race game in which figures b, such as miniature horses, mounted on slides g, are drawn along grooves f by means of cords d, and a winding-drum a. The winding-drum is arranged in a casing filled with spherical or barshaped foreign bodies, which become entangled in the windings, and so vary the speeds of the different moving figures in an irregular manner. In a modification, a projecting piece h, Fig. 8, is formed on each slide g, and is provided with a slit i, which engages a knot k in the cord d. On reaching their destination, the figures are stopped by the drawing- cords branching off more or less vertically, as shown in Fig. 5, and so disengaging the knots k. Barriers, such as inclined planes r, Fig. 9, may be employed, and at these the cords may become disengaged, and the horses be stopped ; or the horses may jump the barriers. The winning chances of eachhorse may be determined beforehand, by surrounding the drum a by a cylinder, divided into as many compartments as there are cords d. Into each compartment a certain amount of foreign matter is introduced, a small quantity representing a greater, and a large quantity a smaller, load to be carried by the horse. Slits are provided in the cylinder to admit the winding-cords, and the compartments are closed by slides. Another modification of the winding arrangement is shown in Fig. 13, in which a separate spool s for each cord is loosely mounted on the drum. The spools sand hand-crank u may be connected by friction to one another, and to the drum by means of a nut t, and washers x. When the nut t is loosened, the cords d may be wound separately off each spool. The winding-drum is arranged in a semi-cylindrical casing w. Projections v on the spools s raise the foreign bodies, which may then drop into the windings.

Title: Improvements in Negative Electrodes for Electric Accumulators and in the Method of Forming them.
Filed: 1902-12-18
Granted: 1903-05-07
Abstract: 28,013. Chloride Electrical Storage Co., [Soc. Anon. pour le Travail Electrique des MÚtaux]. Dec. 18. Secondary batteries.-Relates to negative electrodes, and consists in making them with the active metal in a crystalline form by keeping the electrode, on which is the active mass to be reduced, at an electrical pressure as far removed as possible from that which determines the evolution of hydrogen as a product of electrolysis. For this purposes, the electrode may be made the positive pole of a couple the other member of which has a higher cathodic tension than that of the metal to be produced by the reduction. A list of the principal metals classified with regard to their electronegativeness is given in the Specification. For example, crystalline lead is prepared by reducing an oxide or a salt of lead with the aid of an electrode of magnesium, zinc, or cadmium. The electrolyte may be hydrochloric acid, a solution of the chloride of the metal (magnesium &c.), or a solution of an alkaline chloride. The size of the crystals varies inversely with the density of the current, and, with a given current density, depends on the degree of solubility of the compound used. The capacity of the cell is greater the smaller the crystals. In reducing the metallic oxides, it is advantageous to use an electrolyte which slightly attacks the oxide, forming an insoluble salt or one that is slightly soluble, but it is also possible to effect the reduction in an electrolyte which forms with the oxide a salt which is more soluble in the electrolyte than the oxide itself. The invention is applicable to accumulators having cathodes of iron, nickel, or the like in an alkaline solution.

Title: Improvements in Shaft Boring Apparatus and the like.
Inventor: FRIEH EDUARD
Filed: 1903-07-14
Granted: 1904-05-19
Abstract: 15,602. Frieh, E., and N÷llenburg, R. July 14. D e e p - boring.- For sinking shafts through wet ground, a group of percussive or rotary tools are mounted so that they can be driven directly and close to the point of application. In the form shown in Fig. 4, independent electric solenoid drills F are mounted in tubes C, which pass through a watertight casing A that acts as a float to relieve weight of the boring - head. Current is supplied to the drills from the surface through the ropes T, which support the mud drum J. The lower part A of the head is mounted under the mud drum J by rollers, so that it can be turned by the rods H for the tools to cut all over the floor of the shaft. Flushing- water is sent down through the hollow rods Hand flows up outside the head, depositing the spoil in the drum. The head is shown as feathered on the rods, so that it can be turned by them, or lifted without withdrawing the rods. In other forms, the head may be fixed to the rods and the mud drum may be lifted independently. One tool C<1> is shown as inclined, so that it can cut at the centre, and a similar arrangement of pivoted tools may be thrown out laterally by springs to enlarge the shaft or to cut under the tubbing. The undercutting may also be effected by mounting the head eccentrically on the rods H, in which case the tools should be stepped to cut in terraces. Instead of solenoid drills, any other form of percussive or rotary drills may be used, and one form is shown in which all the drills are driven through spur gearing from a single motor mounted in the head, each drill being retracted against the action of a spring by a crown-cam and being furnished with the usual rifled rotating-gear.

Abstract: 20,945. Allison, C. A., [Word, W. W.]. Sept. 29. Rock drills.-The ends of rock drills are given a cruciform shape and the corners of the wings are bevelled off, to allow for the spread of metal caused by the sharpening, between dies carried by a hammer 1, Fig. 2, and its anvil. The sharpening is performed by narrow-ended dies 17, 18 sliding in guides in a casing 23. The end of the drill 3 is supported by an anvil 4 adjustable on guides 13 by a power screw 14. The dies 17, 18 first operate at the centre, and are moved outwards by a cam-plate engaging pins on the die guides and provided with a handle 29. A horizontal hammer 7 delivers blows to the dies. The hammers are controlled from a balanced treadle shaft 60 which gives motion to a bell-crank lever with pins taking into slotted links 51, 55 connected to the valve spindles, one of which is shown in detail in Fig. 15, where the valve 70 and its chamber are turned through 90‹ with respect to the rest of the Figure. The end 47 of the valve-rod carries a throttle valve 42, working over a triangular hole 44, and a piston 41. The other end of the spindle abuts against the distribution valve 70 of the hammer. When the shaft 60 is free to turn, the pistons 41 cause it to set in a central inoperative position, the valves being in the position shown in the Figure, and steam or air is supplied through small holes 45 to the valve 70, which are held back to fix the hammers in their backward positions. A movement of the treadle either way operates one or other of the valves, due to the slotted links, and the strength of the blows is governed by the opening given to the ports 44.

Granted: 1904-08-18
Abstract: 13,951. Stiefel, R. C., and Nicholson, J. H. June 20. Rolling.-A tube is rolled between continuouslyrotating rolls, and after each pass is returned through the same grooves to the front of the rolls, the upper roll being raised to permit the return. The tube is fed from a trough 17 by the piston of a power cylinder 38 on the trough, and is rolled over a mandrel attached to one of a number of rods 24 fixed at their rear ends in a stop 25 and extending through supports 26. When the tube is clear of the rolls, the upper roll is raised and the mandrel disconnected. The tube is then returned to the trough by a stripper 29 carried by a trolley 28 operated by a cylinder 31, the stripper passing between the rolls to clear the tube from them. The upper roll is then set down and the operation repeated. The supports 26 are mounted on side rods connecting the stop 25 to the roll housings, and are cut away to clear the stripper. The trough is mounted on wheels so that it may be adjusted to bring the tube opposite any pair of grooves in the rolls, rack-and-pinion gearing being used to ensure the parallelism of the trough. One mandrel rod only may be provided, which is then shifted laterally as required. The upper roll is adjusted by a rack, operated by a power cylinder, and connected by gearing with the nuts of the adjusting-screws. The piston-rod of the cylinder carries a collar, engaging an adjustable handwheel, so that the setting down of the roll may be accurately determined. The construction of the stripper and feed-trough may be varied. In one arrangement, there are at each side of the rolls one or more pairs of rollers, which serve to return the tube into the trough 17. The rollers at the front may be reversed to act as feed-rollers, the cylinder 38 being then dispensed with.
