Patent GB-190110275-A (GB)
Title: Improvements in Controlling Electric Motors.
Filed: 1901-05-17
Granted: 1901-07-13
Abstract: 10,275. British Thomson-Houston Co., [Day, M. W.]. May 17. Steering - gear.- Relates to means for controlling electric motors from a distance, more particularly appli. cable for use in connection with the steering of ships. The motor 1, connected with the rudder-actuating mechanism 2, 3, 4, has its field winding 5 excited from a source of constant potential, e.g., the ordinary ship's mains 6, 7, and its speed and torque are varied by varying the electromotive force impressed upon its armature 8. For this purpose, the armature 8 is supplied with current from the armature 11 of a directcurrent generator 12, the voltage of which is varied by varying the excitation of its field 13. This variation is effected by means of a rheostat 14, forming a part of the transmitting-apparatus, and composed of resistances connected at intervals to the segments of a commutator 35, over which moves an arm 38 carrying a pair of contacts 33, 34, in connection with the field winding of the generator. When the motor has been started into operation, the current supply to the generator 12, and, consequantly that to the motor 1, is progressively shut off by means of a synchronous motor 17, which ultimately returns the contact-arm of the rheostat to its neutral position. The fixed winding of the synchronous motor 17 is connected at equallyspaced points to corresponding points in the ring winding of a closed-circuit rheostat 26, provided with a commutator 27, over which moves a contactarm actuated through gearing 32 from the rudder or other driven part. By thus shifting the polarity of the ring 26 through a certain angle, a corresponding movement of the synchronous motor takes place. Further details of the mechanism are given in the Specification, and a modification is described in which starting is effected by rotating the rheostat commutator, and stopping is brought about by rotating the contact arm by means of the synchronous motor. For the purpose of indicating the respective positions of the steering-wheel and rudder, a device may be employed consisting of a screw-driven pointer in connection with the steering-wheel and a similar screw-driven pointer operated through the synchronous electric motor from the rudder.

Title: Improvements in Swings.
Inventor: KERR GEORGE SMILEY
Filed: 1901-06-03
Granted: 1901-07-13
Abstract: 11,320. Kerr, G. S., and Kerr, J. H. S. June 3. Swings.-Relates to means for suspending swings for exercise and recreation in doorways and the like. In the arrangement shown in Fig. 1, a cross-bar 2 has hinged to it end pieces 3, which can be clamped by screws 14 &c. against top part of the door frame. The hinges are adjustable along the bar 2 by bolts 9 and slots, and blocks 16 are adjusted against the door frame and clamped by nuts 17. The bar 2 carries one or more cupshaped pieces 21, which are formed with bearings to receive trunnions on the ends of suspending- rods 18. The pieces 21 have long slots to allow the passage of the trunnions, the rods 18 being then turned through a right-angle to seat them in the bearings. The rods 18 may be replaced by cords. In some cases, the pieces 21 are fixed directly to the door frame.

Granted: 1902-06-12
Abstract: 13,028. Gunyon, S. E., [Sesino, P., and Zamboni, L.]. June 26. Door and gate opening and closing apparatus.- -Relates to an apparatus in which a door or gate is opened by the weight of a person treading on a hinged plate and closed by a spring. The apparatus is shown in elevation in Fig. 1, mounted beneath double doors Q, Q. When the weight comes on the free end of the hinged tread plate P, a wedge V connected to the free end of the plate pushes the sliding bar b to one side. On the bar b are racks which gear with pinions t on the pivots of the doors Q, and thus open the doors. The doors are closed by a spring S, which pulls back the bar b to its normal position. There is a tread plate P on both sides of the doors, the wedges of which push the bar b in opposite directions.

Title: Improved Method and Apparatus for Transmitting Heat from one Fluid to another by Means of Plates.
Inventor: STILL WILLIAM JOSEPH
Filed: 1904-03-09
Granted: 1905-03-09
Abstract: 5765. Still, W. J. March 9. Water-heaters, gas.-Apparatus for transmitting heat from one fluid to another is composed of tubes having conducting- discs passing through their walls. The applications to steam boilers, water-heaters, geysers, feedheaters, and radiators are mentioned. Figs. 1 and 2 show longitudinal and end views respectively of an element of a flash boiler. It consists of a series of circular discs 2 2 alternating with spacing-rings 1, the whole being secured together by internal bolts 3. These pass through elongated slots 4 in the plates, and are held in their correct positions, to allow circulation, by small tee-bars 10. The plates or discs 2 are also formed with slots 7 radiating from a hole 8, the slots in the several plates being arranged out of line with each other. The discs 2, instead of being circular, may be oval, as shown in Fig. 14, rectangular as in Fig. 15, heart-shaped as in Fig. 17, spiral or involute-shaped as in Fig. 19, or starshaped. The heart-shaped discs are particularly applicable where only one row of tubes is employed, as shown in Fig. 17. A baffle 32 deflects the heating-gases downwards on to the central portions of the discs before they escape to the chimney. The spiral or involute discs shown in Fig. 19 attain their maximum width at a point 34 opposite the outlet openings for the heated gases ; a baffle is also provided in this case to confine the gases to the spaces between the discs. In apparatus of the vertical type, such as vertical boilers and the like, the discs are preferably rectangular. Fig. 20 shows in plan a geyser fitted with these discs. Each disc has a pair of opposite corners cut away to allow the passage of the flame &c., and the several discs are so arranged that the cut-away corners in one disc alternate with the plain corners of the discs next above and below. In some cases, the securing-bolts 3, Fig. 1, pass through the discs outside the spacing-rings; or they may form part of a frame for securing together the discs and rings of several tubes. The latter arrangement is shown in Fig. 16 as applied to a water-heater, the endplate 18 of the frame being fitted with screw adjustments 29 for the tubes.

Abstract: 6116. Lorenz, C. Dec. 21, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Shooting-galleries.-Relates to an electric apparatus for aiming and shooting practice, a ball q, supported by a jet of water r, being used as a target. When the gun a, carried in the ball socket c, is pointed at the centre line of the jet and the trigger is pulled, the spring-pressed rod d is depressed into contact with the thin conducting-strip g, closes the circuit, excites the electromagnet m, closes the stop-cock p, and so causes the ball to fall. If the gun is not correctly pointed, the rod d does not come in contact with the strip g. In this case, the closing of the cock may be effected by an electric time switch. Coin action.-On inserting a coin, the switch v closes the circuit i, h, l, t, excites the electromagnet s, and opens the cock p.
