Patent GB-190508158-A (GB)
Title: Improvements in Electric Motor Starters.
Inventor: HORTON ALBERT J
Filed: 1905-04-17
Granted: 1905-11-09
Abstract: 8158. Horton, A. J. Nov. 2, 1904, [date applied for under Patents Act, 1901]. Switches.-In a shunt-motor starting-switch having armature and field rheostats, the field resistance remains short-circuited while the armature resistance is being cut out by forward movement of the handle, and is afterwards varied independently by forward or backward movements. The field rheostat arm 17, Fig. 1, carrying the handle 19, moves over the contacts 2, connected to resistances underneath the base-plate 1, and pushes the arm 11 over the contacts 6 of the armature rheostat by means of stops 16, 15 fixed on the respective arms. The brass sector 8, connected by a wire 32, Fig. 3, to the right-band stud of the field rheostat, engages with an additional brush 10, Fig. 3, on the arm 11, and short-circuits the field resistance. The short-circuit is broken when the arm 11 reaches the extreme right-band position, where it is held against a spring, by a magnet 20, which may be connected across the line, as shown, or otherwise. The field resistance is subsequently varied by moving the arm 17 backwards and forwards. Finally, the brush 18, after travelling over the rheostat shuts, engages the 'dead' studs on the extreme left, and so adds the whole armature resistance 7 to the field, the two left-hand studs of the armature and field rheostats being connected by a wire 33. Further backward movement causes the projection 17<a> on the arm 17 to engage the stop 11<a> and pulls away the arm 11, which flies back to the 'off' position.

Abstract: 26,502. Brosius, S. G. Dec. 19. Razors, safety. The blade H, Fig. 3, which may have two cutting-edges h, is held by clips I at the extremities of spring arm3 D. The arms are pivoted to the handle A by a bolt E, Figs. 3 and 8, which can slide in a slot a in the handle. A plug F pressed downwards by a spring G acts on the bolt to lock it in position, and yet allows it to move in the slot along the handle. The blade when in position lies on rests c<1> on a blade-supporting plate c, Fig. 3, its corners resting against stops c<2>. A spring B acting on the spring arms D holds the blade in position. To remove the blade, it is raised from the plate c by moving the bolt E along the slot a, and then the arms D are swung over at right-angles to the handle and locked in that position by the plug F coming into engagement with a flat portion of the bolt E. The spring arms are then forced apart by the push-bars J and the blade taken away. The clips I are formed with curved jaws I<3>, Fig. 10, and have a square bearing I' which fits in a square bearing d, Fig. 6, in the arm D, one side d<2> of which is a spring arm to allow the clips and the blade with them to be rotated by the head i, so that the edge of the blade to be used may be changed without removing the blade. The bladesupporting plate c may have a guard to protect the edge of the blade that is not being used.

Granted: 1906-07-12
Abstract: 1903. Couper, H. R., and Lindsay, W. H. Jan. 25. Variable-speed gearing ; clutches.-Relates to coilfriction clutches of the type described in Specification No. 2995, A.D. 1893, constructed to allow overrunning so that a number of such clutches may be employed on a common shaft in a variable - speed gearing applicable to lathes, motor-cars, &c. The device comprises a coil clutch 4, and a friction clutch 7, 9 mounted to have a free-wheel action on the hub 13. The main clutch comprises a coil 4 connected at each end to loosely mounted members 3, 7 and wrapped round a drum 1 fast on the hollow shaft 1<a>. The loose disk 7 is clutched to the shaft by a flexible disk 9 with radial cuts 9<a>, carried by a slidable hub 13. When the disk 7 rotates, the coil 4 pulled by the link 6 tightens on the drum 1 and carries round the member 3 with its pioion, pulley, &c. to be driven. The free-wheel clutch arranged within loose collars 9<c>, 22 and a sleeve 11 on the hub 13 may comprise a coil 12 the head 12<a> of which has a limited movement in a recess 14 in the sleeve 11, while the tail 12 is tapered and adapted to be gripped by a roller 15 in a packet 16 also in the ring 11. When the disk 9 grips the disk 7, the rotation of the shaft 1<a> causes the roller 15 to travel up ard grip the tapered coil end 12<b> and so transmit drive. Upon overrunning, the coil 4 loosens, while the free-wheel clutch also comes mto action. In the application to variable-speed gearing, such a clutch device is fitted to each train of gearing so that only the clutch driven at the highest rate operates, the others overrunning. Modifications of the free-wheel device are described. The roller 15 may be replaced by a pivoted segment with a serrated periphery, the tail 12<b> being correspondingly serrated, or the coil end may be simply distorted to curl inwards and grip of itself. Ordinary free-wheel pawls &c. may be used.

Title: Improvements in and relating to Rotary Engines
Inventor: ANDERSON HARRY PERCIVAL HARVEY
Filed: 1907-08-13
Granted: 1908-08-13
Abstract: 18,294. Anderson, H. P. H. Aug. 13. Movable-abutmerat type, with abutment sliding axially. The circular pistons attached to the disk u rotate in a working chamber which is provided with an axially-sliding abutment b. The abutment is supported by a guide q and is reciprocated by a crank m, which is rotated through half a revolution by the cam-operated racks j. The pistons are packed with ordinary split rings. In an engine with two diametrically-opposed pistons, the packing-rings of the two pistons are balanced by connecting them together by a tie-bar u. In an engine having one piston, the rings are connected by a bar with a balance weight on the other side of the shaft. The cross-section of the abutment is arranged so that the pressure of the steam upon the end of the abutment is sufficient to overcome the friction on the outward movement. The abutment passes through a rectangular stuffing-box e. It may be provided with a round bar so that an ordinary stuffing - box may be used. Steam is admitted through the valve y and passes through a reversing- valve b<1>. The valve y is periodically opened by the spiral-edged cam z, which is splined to the shaft and may be moved laterally by the governor. In place of the cam z, a plain cam may be used operating a rod between which and the valve-operating rod a tripping-piece is inserted as determined by the governor. The reversing-valve b<1>, as shown, connects the inlet with the right-hand port, and the left-hand port with the hollow of the valve which leads to the exhaust. By rotating the valve slightly in a counter-clockwise direction, the connexions of the ports are reversed. For use as an explosion engine, the explosion chamber casing, Fig. 4, is fitted above the valve y. The explosive mixture is compressed by a pump or pumps and passes into the chambers d<1>, e' alternately as determined by the valve v<1>, which together with the valve v<2> is operated to open each chamber once in two revolutions of the engine. The mixture is exploded in these chambers, and passes through the ports of the valve v<2> to the valve y. The chambers are scavenged periodically when the valves k<1> are opened. The compression pumps are driven by cam-actuated levers which are made telescopic so that the fulcrums may be moved to vary the stroke of the pump plungers.
