Granted: 1905-05-04
Abstract: 28,486. Gibbon, T. H. Dec. 27. Wheel track for vehicles are formed by enlarging the upper face of tramway rails ; various devices are described for setting these rails in the roadway and for fastening them to bridge girders. Figs. 2 and 9 show one form. The bed-plates B are made concave beneath to grip the roadway, and are provided with tongues 12 which are bent over the base flanges 42 of the rail G. The upper surface 10 of the rail is made broad, and one edge 10<2> has ridges or flanges 12<a> on which tram wheels can travel. The other edge has a flange 13 to increase the grip on the roadway. The ends of the rails are formed so as to overlap each other and form a continuous joint. The webs of the rails have equidistant slots to receive the ends of the tie-bars E, which are fixed by sliding into the slots and then giving the bar a quarter-turn. Wedge keys are then inserted to fill up the slots. In the modified form shown in Figs. 3, 4, and 10, a continuous sleeper C is used, having a groove 3 to receive the vertical web 4 of the rail. The bed-plates A are connected to the sleepers C by sliding the T-piece 2 into the hole 1 and then giving the bed-plate a quarter-turn. T-shaped holes 5 are provided in the longitudinal sleepers in the vertical part of which the tie-bars are inserted. The web 4 of the rail is then let down into the groove 3, and held in position by wedge keys. Fig. 6 shows a method of attaching the rails to the girders of bridges. A strap J is passed round the girder and is fixed in position by the key F. This strap has a hook which engages with a hole in the vertical web of the rail. Longitudinal wooden sleepers form supports for the upper surface of the rail.

Title: Improvements relating to Brake Mechanism for Railway and other Vehicles.
Inventor: BROWN HARVEY EZRA
Filed: 1905-02-01
Granted: 1905-11-02
Abstract: 2023. Brown, H. E. Feb. 1. Brakes.-Relates to means for automatically reducing the pressure of the brake blocks on the wheels of railway or other vehicles as the speed is reduced and the coefficient of friction increased. The tangential pull of the brake blocks, when it exceeds a certain limit, is arranged to act through rods and levers upon the lever which applies the blocks, in such a manner as to reduce the force acting upon it, whether that force be applied by an automatic pressure or vacuum brake or by other means. In an arrangement shown in Fig. 1, adapted for a vacuum brake, the brake blocks a are connected by rods a' to levers b, each having two fulcra b<1> so as to act in either direction of running. Springs prevent the levers from moving until the pull exceeds a certain limit. The levers b then act through a rod c and a pawl h upon a toothed quadrant g fixed to the brake lever g. A stop i acting on the tail h<1> of the pawl h disengages it when the pull on the rod c ceases. In a pressure brake, the rod c may act through a lever and a pawl upon a toothed rod connected to the piston-rod. In the case of a bogie vehicle, the rod c is jointed to permit lateral motion, and the stop i is connected to a bracket on the bogie by a jointed rod, parallel to and carried by the rod c.

Title: Gas Turbine with a Rotating Explosion-chamber and Automatic Valve Motion.
Inventor: FRANZ STEFFENS
Filed: 1905-04-10
Abstract: 7847. Steffens, F., and Rothe, C. April 9, 1904, [date applied for under Patents Act, 1901]. Void. [Published under Patents Act, 1901.] Gas turbines.-The drums 1 are connected together as shown'in Fig. 1 (Sheet 1), to compensate the axial end-pressure, and they contain within them a rotating explosion chamber which is subdivided into several subdivisions. The turbine sucks in the combustible gas past the valve 9. A switch may be actuated so that either of the sparking- plugs 15, 16, 17 are put into action. As soon as the gas is ignited, the valve 9 is closed and the supply temporarily stopped. The.valve 9 may contain within it a contact-maker, Fig. 3 (Sheet 3), to economize the current. By actuating the plugs 15, 16, or 17, more or less gas is ignited, thereby regulating the power. To prevent waste of gas on stopping, an atmospheric valve 25 is opened. Several modifications of the internal chamber are described. In one, a spirally-wound tube is used; in another, the subdivisions are formed by baffles; and, in a third, provision is made for cooling by making the chamber of concentric tubes and arranging them so that the cooling-medium may pass through alternate interspaces. Blades are attached to the spaces when utilizing the atmosphere. In the turbines shown in Fig. 3 (Sheet 2), the power required for sucking the gas-mixture is saved by connecting the alternately - operating valves 9 together and providing fans.

Abstract: 16,916. Kyle, T. D. Aug. 21. Preserving fish. - The fish as it arrives from the sea is placed in a tank a provided with a perforated cover i and containing sea-water which has been concentrated to lower its freezing-point. The temperature is lowered to near zero by means of the coils d of a refrigerating- system. By means of a pump f, the water is circulated through a filter e containing compressed sponge and a perforated tray b, in the bottom of the tank, containing animal charcoal whereby impurities and obnoxious gases &c. are removed. The fish is then removed from the first purifier and, after being gutted and cleaned, is placed in trays, also filled with concentrated sea-water, which rest on refrigerating-coils j, whereby the temperature is reduced below that in the tank a. Purification of the sea-water is accomplished by circulation through charcoal filters p and also a sponge filter as before, the series of trays being connected together by pipes o, n for the purpose. In this condition the fish may be kept for daily sales. If for storing, the fish is removed from the trays m<1>, sorted into smaller trays u and covered with pure sea-water, and placed in a rapid freezer c and frozen into solid blocks, after which they may be placed in cold storage until required. A collecting- ship may be employed, provided with the first purifier, to keep the fish in good condition until it reaches the central depot.
