Title: Improvements relating to Means for Controlling the Trolley-arms of Electric Tram-cars Driven from Overhead Wires
Filed: 1901-04-15
Granted: 1901-10-26
Abstract: 7701. Milloy, P. D., and International Trolley Controller Co. April 15. Electric railways and tramways with overhead conductors. Relates to a trolley rope holding and pulling down apparatus. Collectors.-The trolley rope 3 is led round the sheave 32 to the spring barrel 2, which takes up the slack under ordinary conditions of running, but, if the trolley runs off the trolley wire, the pull on the rope and sheave liberates the catches 5, so that the spring 4 can come into play to pull down the head 30. This tends rapidly to unwind the rope from the barrel, and throws out a spring pawl 25 thereon into engagement with a fixed rack so as to hold the barrel ; further motion of the spring 4 then pulls down the trolley pole. The head 30 carries a second sheave 38, round which passes the rope 39 normally kept wound on a second spring barrel 37 ; by pulling on the handle 41 at the free end of this rope 39, the head 30 is again lifted until the catches 5 hold the spring 4 in tension. The spring 4 is held by a swivelling attachment in the base 7 of the standard, which is provided with covers at 13 and 21 for access to the working parts.

Title: Improved Method of and Apparatus for Making Coils particularly applicable for Electrical Apparatus.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-02-10
Granted: 1904-02-04
Abstract: 3158. Carolan, E. A., [General Electric Co.]. Feb. 10. Bending.-Relates to apparatus for making coils of comparatively large cross-section for electric and other uses by bending a bar, rod, or strip of copper or other metal or alloy round a mandrel in a lathe or other suitable machine. The bar 34, Figs. 1 and 2, is led through a guide 13 to the mandrel 1, and is held at one end in a rotatable twisting-head 2 driven by the lathe &c. The twisting-head 2 has a central hole in which the mandrel rests loosely, and is recessed longitudinally to receive the end of the bar 34, a sleeve 5 and setscrew 6 being provided to secure the bar. The face of the head 2 towards the guide 13 is of helical form, starting from the rounded-off portion 7 at one edge of the slot and terminating at the other edge 12. The guide consists of a bottom plate 13 with a cap-piece 16 and a cover-plate 23. The plate 23 is adjustable by means of bolts 24 and set-screws 25, and carries a roller 22 for forcing the bar 34 against the guide-surfaces 14, 15 of the plate 13. The cap-piece 16 is secured to the plate 13 by bolts 19, 18, the latter passing through a lug at right-angles to the body of the piece 16. The face of the piece 16 towards the head 2 is of helical form, and is smoothed off at the line of intersection with the surface 15 of the plate 13. In the operation of the apparatus, the bead 2 and mandrel 1 are gripped between the head and tail centres of a lathe, and the plate 13 is secured to the slide-rest, the feed-motions of which are disconnected to allow the slide-rest and guide to move along the mandrel under the pressure of the coiled bar 34. To obtain a coil having windings of rectangular section, the bar 34 is made of trapezoidal section, the angles at the intersection of the inclined edges with the shortest parallel edge being chamfered off to prevent the windings from touching at their inner parts in the case of closely-wound coils. Fig. 5 shows a mandrel 26 carrying a small fin-like screw 28 which may be screwed through the coiled bar to separate the turns to any required small extent. The sleeve carrying the screw 28 is engaged with the mandrel 26 by a pin 30, and is forced against it by a sleeve 27 and nut 29. Fig. 7 shows a finished coil 34 cut from a long length of the coiled bar and provided with brazed angle-pieces 31 and bolts 32.

Filed: 1903-07-24
Granted: 1904-05-26
Abstract: 16,380. Gibson, A. H. July 24. Rock drills, percussive. Valveless percussive drills are driven by connecting the ends of their cylinders to the ends of the cylinder of a separate air-compressor, which is preferably driven through gearing by a rotary motor. One end only may be connected, and the connections may be made through tapering flexible pipes at N<1>, O<1>. A section of the drill is shown in Fig. 2. The piston-rod a is hollow with closed ends. One end is rifled to work in the rifled sleeve d, carrying an ordinary ratchet mechanism e. A passage m admits air behind this end of the piston-rod to increase the effective area at the rear of the piston. An airtight cap j, containing a spring and plate j<2>, closes the rear end of the cylinder and acts as a buffer ; it is held at the sides by spring bolts, which hold the cylinder covers. The feed-nut o is fixed to the cylinder, and the tool is held by a clamping-piece a<2> and U-bolt a<1>. The working of the drill is controlled by a plug valve, Fig. 4, which opens or closes communication between the rear end of the drill and the atmosphere, and thus the compressor may run continuously and may serve several drills. The compressor has a trunk piston A, Fig. 10, driven by a crank in an enclosed chamber, which has removable sides D' carrying the bearings for the crank shaft and also has a removable door W. Gearing of raw hide &c. is placed outside the chamber. The larger working end of the compressor is connected to the rear end of the drill. To make up for leakage, non-return spring valves P, P' are fitted on the ends of the cylinder.

Patent GB-190323523-A (GB)
Title: Astatic Magnet, and Process for the Making of same.
Inventor: ZACHARIAS JOHANNES
Filed: 1903-10-30
Granted: 1904-08-11
Abstract: 23,523. Zacharias, J., and Lasker, E. Oct. 30. Magnets.-An astatic magnet is formed of one homogeneous piece, by magnetizing the latter in a perfectly-symmetrical manner about its centre of symmetry. As examples of bodies having approximately a centre of symmetry, there are mentioned a ball, a hemisphere, a cylinder, and a parallelopipedical bar. Either a permanent magnet or an electromagnet may be used for magnetizing the body ; in the latter case, the current need only pass during magnetization, thereby allowing the article to be symmetrically brought up to or removed from the magnet without any risk of disturbing its magnetism. To magnetize a steel cylinder, the lower ends of a permanent horse-shoe magnet have soft wedge-shaped pole shoes, the edges of which are at a distance apart nearly equal to the diameter of the cylinder. The centre of the cylinder is brought horizontally upwards towards these edges and then withdrawn, so that throughout the movement its centre of symmetry is exactly in the axis of symmetry of the magnet. To magnetize a plate, the shoes of an electromagnet are coned so that their points almost touch in the centre of symmetry of the plate, which is brought up before, and removed after, the current has been turned on. In any case, the object to be magnetized may be rotated or otherwise moved while under the influence of the magnet, but so as not to effect the symmetry of the arrangement, or the components of the field may be altered, or the field may execute a movement after the object has been introduced. The magnet produced is in all cases perfectly astatic, and is extremely sensitive to light, heat, electricity, magnetism, or other radiating energy, the angle of movement being constant for the same magnet, the same form of energy, and the same amount of energy. It may be used for purposes of instruction, for measuring various forms of energy. or for transforming one form of energy into another, which is then utilized, such as for transforming heat directly into mechanical effect.

Title: Improved Method of and Apparatus for Incandescent Gas Lighting.
Inventor: TRESENREUTER GUSTAV
Filed: 1903-11-13
Granted: 1904-01-28
Abstract: 24,745. Tresenreuter, G. Nov. 13. Incandescent gas lamps. - Increased luminosity is obtained with a mantle of less superficial area, and with a smaller supply of gas than usual, by admitting to the ordinary mixing-tube a insufficient air t o ensure complete combustion, and supplementing the air by oxygen, supplied at the same pressure as the gas by an external tube or ring l, which is bent inwardly at its upper edge n, and discharges below the outlet of the mixing-tube a. The ordinary atmospheric flame v is thus enveloped in a film u of oxygen, and the completion of the combustion is ensured by the employment of a mantle w closed at its upper end, so that the products of combustion can only escape through the meshes of the fabric. The mantle is suspended by an asbestos thread from a holder t, mounted by a clamp s on the supply pipe or pipes k, q. The gas supply through the nozzle is controlled by a screw below it.

Abstract: 4997. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Feb. 29. o-Hydroxy-diazo-naphthalene sulphonic acids are prepared from diazotized naphthylamine di- or polysulphonic acids in which the amido group and a sulpho group occupy the ortho position, by treating them with alkaline or alkaline-earth carbonates, bicarbonates, or acetates, as in Specifications Nos. 6615 and 23,993, A.D. 1902, and No. 27,372, A.D. 1903, and, either during or after the substitution of the hydroxy group, with chlorine or a hypochlorite, or other equivalent oxidizing- agent, whereby the displaced sulpho group is oxidized to sulphuric acid and prevented from disturbing the subsequent production of azo bodies. Dyes, artificial.-The above diazo bodies yield o-hydroxy-azo colouring-matters when condensed with an azo colouring.matter component, such as #-naphthol. In an example, the acid sodium salt of #-naphthylamine-1 : 5-disulphonic acid in a mixture of water and sulphuric acid is diazotized with aqueous sodium nitrite, and the free acid is neutralized with soda. The temperature is kept at 25-30‹ C. and an aqueous mixture of calcined soda and sodium hypochlorite is added drop by drop. The substitution is complete when a test portion does not yield a red colour with a dilute caustic soda solution of #-naphthol. To the solution, which must not react with starch-iodide paper, #-naphthol in caustic soda is added, with further addition of caustic soda and common salt. After long stirring at a temperature of 40‹ C., the colouring-matter is filtered off, pressed, and used in the form of paste. alpha-Naphthylamine-2: 4-disulphonic acid may be similarly treated, or else, after diazotizing, calcined soda is added. The whole is now cooled to keep the temperature below 15‹ C., and gaseous chlorine, preferably diluted with air, is passed in until the substitution is complete. The process is then continued as before.
