Abstract: 18,550. Maclean, J. Aug. 28. Commutators for dynamos and electric motors are made of a number of segments so built into a ring that the inner ring-surface forms the hearing-surface for the brushes. The segments a, Fig. 2, of wedge shape and insulated from one another by mica e, are held together by two solid rings b, c of vulcanized fibre, parts b<1>, c<1> taking into the dovetailed back part a' of the segments. A circular channel d on one ring takes into a projection c on the other, and screws f hold the whole together. The outer surfaces of the rings b, c may be grooved to hold crossconnections where advisable, while the connections to the segments may be made by means of pins screwed into them through the rings b, c, such pins being brought out at the top or the sides. The commutator is fixed to a dynamo &c. in any suitable way, and the above construction is especially advantageous where the commutators are not of large diameter.

Abstract: 10,677. Steel, M., and Thornton, R. May 9. Carburetting.-In an apparatus for carburetting air or gas, a vessel a is supplied with hydrocarbon through a valve b closed by a spring p, the vessel a being closed by a cover c having an inlet pipe d and an outlet pipe or pipes e. The pipe d is sealed bymercury or other heavy liquid between concentric tubes f, g, the inner of which communicates with a chamber h formed with or carried by the float j. The chamber h has a series of outlet tubes k, each of which may have at its end a deflecting-plate carried by a spring or otherwise, and may be formed with a sliding extension. The spring p is opened by the float j by means of a screw rod q operated by the milled head r or the like. An inner chamber s, depending from the cover c and having a removable bottom t with openings u, may be provided. In a modification, the air issues from graduated perforations in a flange forming an annular space surrounding the float, and can, in addition, pass below the edge of the flange. The supply of hydrocarbon may be controlled by a separate float, in which case the hydrocarbon is delivered to the carburetter by a perforated pipe, preferably arranged helically within the carburetter. To prevent flooding if the valve worked by the external float should stick, a suitable valve in the supply pipe may be operated by the float j. When the apparatus is used in connection with an internal-combustion engine, the entrance to the inlet pipe d may be cup-shaped and provided with a gauze cover 10, and a valve may regulate the quantity of the induced air. Exhaust gases may pass through the jacket 11 for warming the carburetter. For other purposes, air suitably heated may be pumped or blown into the apparatus. If required, the carburetted air may be filtered through gauze and flannel before passing through the outlet e. A number of inlet pipes may be provided, admitting the air or gas to one or more chambers carried by one or more floats.

Filed: 1905-05-04
Granted: 1905-07-27
Abstract: 9424. Carpenter, L., and Holmes, J. J. May 4. Lift valves; check valves.-The tap or cock comprises a combined stop and check valve for use with beer or other casks when connected to drawing-engines, and is designed to prevent leakage by automatically cutting off the flow of liquid in the event of breakage of the pipe. The body of the tap has a perforated inlet branch b, which is driven into the cask in the usual manner. The outlet l is connected to a beer or other engine. A valve-seating e is formed, upon which rests a heavy plug d of any suitable shape. The plug shown is formed with ribs g, thus leaving passages for the flow of liquid. Normally, the pressure of liquid beneath the valve is not sufficient to raise it, but the suction of the drawing-engine lifts the plug, and the liquid then flows past the valve. A thumb-screw i terminated by a washer k enables the valve to be screwed down to its seat when required.

Title: Improvements in Elastic Fluid Engines of the Revolving Cylinder Type.
Inventor: SPONNECK-MAYER ANGELICA MARIA
Filed: 1905-06-02
Granted: 1906-05-31
Abstract: 11,590. Sponneck-Mayer, Angelica Maria Anna. Countess. June 2. Revolving-cylinder type.-In Fig. 1 is shown a two-cylinder, high-pressure, single-acting steam or other elastic-fluid engine in which the cylinders a, a<1> have their covers bolted to a sleeve c fixed to the main shaft b. The piston-rods d, d<1> extend outwardly, and, through crossheads f f<1> and rods g, g<1> drive brackets h, h<1> which support transverse rods i, i<1> provided with bowls or rollers j, j<1>. The rods i, i<1> are guided by slots k, k<1> which move with the cylinders, and the rollers j, j<1> work in cam-grooves l formed in a fixed frame or in plates secured thereto. Thus the axial pull in the rods g, 9<1> causes rotation of the cylinders and shaft, and, by suitably shaping the cam-guide, the torque may be made practically constant. Steam is admitted to and exhausted from the respective cylinders during alternate half-revolutions by the arrangement shown in Fig. 4, in which an inlet port p and an exhaust port q cut in the cylinder covers and a portion of the sleeve c rotate around portions n, r fixed to the frame of the engine and in which are cut a steam-admission port o and an exhaust port r<1>. The cylindrical piece r closes the exhaust during the working stroke, and the admission and cut-off may be varied by slight modifications of the parts. Reversal of the part driven may be effected by interposing between it and the shaft b any suitable gear-wheel reversing- device, or by a reversing-valve as shown in Fig. 11 in which the sleeves n, r instead of being permanently fixed can be turned about their axes through the required angle and then be securely held in the new position. The port o, for example, would, for reversing, be moved into the position shown in dotted lines. A flexible steam connexion to allow of this motion is described. A modification consists in reducing the overall length of the engine by passing the piston-rods through the inner instead of the outer cylinder covers. A modification of the valve shown in Fig. 4, to permit of compound working, is also described, and a third modification consists of a double-acting, compound engine in which, during each half of a revolution, one cylinder receives high-pressure steam on the inner side of its piston and the other cylinder receives low-pressure steam on the outer side of its piston. The Complete Specification describes this engine with cylinders of the same diameter throughout, but the Provisional Specification states that the pistons may be stepped, or that two pistons of different diameters and working in separate cylinders may be fixed to one piston-rod.
