Title: Improvements in or relating to Safety Valves.
Inventor: DECLERCQ ERNEST FERNAND
Filed: 1899-11-25
Granted: 1900-11-24
Abstract: 23,558. Declercq, E. F. Nov. 25. Safety valves. - In order to compensate for the reduction of pressure under the valve, when it leaves its seat, the valve disc c has a downwardlyextending rod, which carries a disc g and supports a series of spiral surfaces h. A supplementary disc d, working in a suitable chamber, is placed above the valve disc to neutralize any back pressure thereon. The arrangement causes the valve to be lifted from its seat by the pressure on the disc g when such pressure exceeds the normal. In a modification, the spiral surfaces do not extend into the boiler, and are not terminated by a disc.
Patent GB-190000896-A (GB)
Title: Improvements in or connected with Clutch Mechanism.
Inventor: CONTI JAMES TIBURCE FELIX
Filed: 1900-01-15
Granted: 1900-12-31
Abstract: 896. Conti, J. T. F. June 21, A.D. 1899, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Valve gear.-Relates to clutches for use in all cases, as for instance in steering-gears, where a clutch is to be disengaged automatically after a movement of definite extent has been obtained. Figs. 1 and 6 show the application of the arrangement for the regulation by the governor of a Meyer expansion gear, in which the rotation of the valvespindle d in either direction is effected by a projection a engaging with an extension h on the pinions b, c. The object in this case is to make the number of revolutions of the valve spindle a function of the amplitude of movement of the governor and not as hitherto a function of the time during which the clutch continues in gear. The screwed socket f is moved longitudinally by the rise or fall of the governor, so that for each position of the socket there is a corresponding position of the expansion slides of the engine. When the projection a has engaged itself by means of the governor with, say, the pinion b, a continued revolution of the spindle by means of the socket f will cause its disengagement. Instead of the socket f the screwed ring j, which, embracing a muff a about the spindle d, is moved longitudinally by the governor, may be substituted to produce the same result.

Title: Improvements in Uniting Aluminium to Aluminium or other Metals.
Inventor: JOHNSON JAMES YATE
Filed: 1900-04-10
Granted: 1901-04-10
Abstract: 6735. Johnson, J. Y., [Herõus, W. C.]. April 10. Welding.-Aluminium is united or welded to aluminium or other metals by heating it to a temperature below red heat, at which it becomes soft but does not oxidize. If it is to be joined to aluminium, the second piece is similarly heated, and welded to the first by hammering or other equivalent means. The surfaces to be united are thoroughly cleaned before heating. The longitudinal seam of a tube may be welded in this way. Aluminium may be similarly united to other metals, such as silver, which do not become oxidized at a red heat, both metals being brought to their respective welding temperatures. The necessary temperature for the aluminium is ascertained by a slight hammering, to observe whether it has become softened or not.

Title: Improvements in Variable-speed Transmission Gear.
Inventor: HEATLY HARRY
Filed: 1901-02-22
Granted: 1902-02-13
Abstract: 3798. Heatly, H., and Hunt, W. Feb. 22. Variable-speed and reversing gearing for motor cars, textile machinery, &c. The planet-pinions 1, 2, secured together, are mounted in a casing 8,10, fixed on the driving-shaft 9, and gear with a pinion 3 on the driven shaft 4 and with a pinion 5 on the sleeve 6 respectively. The sleeve 6 carries a wormwheel 11, in gear with a worm 12, which is of such a pitch that the wheel cannot drive it, so that the pinion 5 remains dead and the shaft 4 is driven at its highest speed in the opposite direction to the driving-shaft. To vary the speed, motion is imparted to the worm by a variable-speed gear, such as the disc-and-roller friction gear shown. The disc 17, mounted on a stud and pressed into gear by a spring, is driven from the casing 8, 10 by gear-wheels 22, 21 ; the roller 15 is movable along the worm shaft 13 by an arm 24 and sliding-rod 25. As the roller is moved away from the centre of the disc, the worm is caused to rotate in the direction in which the wheel tends to move it, whereby the pinion 5 is allowed to rotate and the speed of the driven shaft falls until at a certain point it becomes zero ; further movement of the roller causes the driven shaft to rotate in the opposite direction. By means of a rod 34 and cam-plate 30 the pivoted bracket 14, which supports the shaft 13, may be tilted upwards to take the worm out of gear ; an arm may be provided on the camplate to shift the roller 15 simultaneously into the position at which the shaft 4 remains at rest. The pinion 5 may be on the driving-shaft and the wormwheel 11 on the casing ; or other trains of gearing may be used. The casing may be driven by belt, chain, &c. from the driving-shaft, which would then carry the friction disc 17. The worm may be of such a pitch as to allow of its being driven by the wheel, and be provided with a brake or other regulating-device.
