Granted: 1903-03-12
Abstract: 8023. Hall, R. F. April 7. Gas or explosive-vapour engines.-A six-stroke cycle engine using heavy oil has three radial cylinders driving the same crank-pin d and enclosed in a water casing. The inlet-valve cams have two swells i<4>, i<5>. One admits a small charge on the first out-stroke which is wiredrawn and compressed on the in-stroke, and then the other swell admits the remainder of the charge, the whole being compressed on the second in-stroke ; the fifth stroke is an explosion stroke, and the sixth an exhaust stroke. By these means, the charge is thoroughly mixed, and so much heating of the air supply is not necessary. The air supply to the carburetter and the mixture passing from it by pipes k, m are heated in the exhaust-silencing pipe i<8>. The inlet valves i<3> are worked through levers o, o<1>, o<2> of different lengths, which are mounted on a ring n and adjusted by a rack and pinion n<3>, n<4>, so that the cylinders may be brought into operation in succession at starting, a special vaporizer being employed with the starting- cylinder. The ignition is timed by a ring q<1> similar to n.

Abstract: 12,996. Jackson, (formerly Jackson), C. L. Rothwell-, and Edge, J. June 10. Ironing-machines; mangling and wringing machines.-Relates to calendering, mangling, and like machines, in which the pressure of the rollers is regulated by hydraulic rams. At each end of a roller b, a small hydraulic cylinder e is fitted in slideways of a frame a of the machine, and is supported by an adjusting-screw f, working through a nut g in the top of the frame a. One end of a bolt i is passed through a ram h of the cylinder e, and its other end secured by a pin to a collar m, which fits into a recess in a block k, supported by bolts l from a flange of the cylinder e, the block k having secured to it two straps n, which support the spindle of the roller b. A coiled spring y encircles the part of the bolt i between the end of the ram h, and the block k, the springs being strong enough to lift the roller b when the hydraulic pressure of the rams is removed. Each end of the spindle of the lower roller c is carried in a bearing o, supported upon a ram p, fitted in a hydraulic cylinder q, which is mounted in slideways in the frame a, and rests on an adjusting- screw r fitted in a nut g, secured in the frame a. In operation, the position of the rollers is first adjusted by the screws f, r, respectively, to suit the diameter of a roller d, so that only a very slight movement of the rams is necessary to apply the final pressure. Instead of applying the improvements to both top and bottom cylinders as shown, they may be applied to only one of them, and, when the bottom roller only is actuated, the springs j are dispensed with so that the roller falls by gravity. Instead of the springs j, any other form of springs with the addition of levers, may be arranged outside the frame a.
