Title: Improvements in Water Valves.
Inventor: MILNER ARTHUR
Filed: 1899-09-14
Granted: 1900-07-14
Abstract: 18,584. Milner, A. Sept. 14. Lift valves; actuating valves.-A water supply valve in which the operating-parts are within the valve-chest and which is suitable for controlling the water supply used for quenching coke is shown in Fig. 1. The inlet I is normally closed by the vaive H, the spindle of which carries a piston C working in the upper part of the casing. A passage K in the casing connects the water inlet with the chamber J above the piston so that the pressure on the piston keeps the valve closed. By means of an auxiliary valve L the pressure can be removed from the piston by opening the aperture K<1> leading to the discharge chamber, thus allowing the water under the main valve H to raise it and pass into the discharge chamber. In a modification, the connecting - passage is formed outside the casing.

Patent GB-190004816-A (GB)
Title: Improvements in Journal Bearings.
Inventor: DAVIES GEORGE
Filed: 1900-03-14
Granted: 1901-01-26
Abstract: 4816. Davies, G., [Lee, W. T., and Mellor, N.]. March 14. Rollers and roller heads.-Relates to covers of caps for bearings for the journals of rollers used in spinning and winding machines &c. The bushes 5 are preferably of wood, so prepared that it does not need lubrication, and the journals 3 preferably turn within them. The cap 9, Figs. 3 and 4, is fixed to the pivot 10 which is preferably surrounded by a spring 12, though in some cases the weight of the cap, and the fact that the pivot is at one side, may be relied on to hold it in place. When the cap is lifted so that the projections 14 are clear of the bearing 2 it may be swung round on its pivot. When swung aside, the tail end 9<a> of the cap may rest on a rib 15 formed on the hanger or other part which supports the bearing. The pressure of the spring causes sufficient friction to prevent the cap from being accidentally displaced. The cap may be formed with a downwardly-extending flap, which covers the end of the bearing. When the pressure on the roller &c. to be supported is invariably downwards, a slotted bush 5<a> may be used, as shown in Fig. 4. In this case, when the caps are swung aside, the roller may be lifted out without disturbing the bushes. If the bearings are closed at the ends, the flaps on the caps are unnecessary. If on the other hand the upward openings are reduced, so that the bushes can only be removed endways, the caps need not cover the bearings. It is, however, preferable that they should do so, to keep out dirt &c. In the modification shown in Fig. 5, a cover 7 of springy material is substituted for the caps. This cover is retained in place by flanges 8 or by a single flange, above or below.
Patent GB-190005897-A (GB)
Title: Improved Means for Advertising
Inventor: REEVES JOHN HORACE
Filed: 1900-03-29
Granted: 1901-03-23
Abstract: 5897. Reeves, J. H. March 29. Magic - lanterns. - Advertisement discs 8, 9, carried on arms 6, 7, are brought into position between the lenses 3, 4 of a magic-lantern arrangement so that the advertisements are thrown on a screen, by means of a chance device operated electrically which determines the disc to be brought into position. One or other of the coloured discs 12, 13, mounted on the arms 10, 11, is at the same time, and on a similar chance principle, brought into position behind the advertisement disc. In front of the lens 3 is a shutter 15, which constitutes one of the counterweights of a clockwork mechanism, so that it is lifted as the clock runs down, and by pulling it down the clock is again wound up. The shutter is connected by a wire with a pivoted lever 16 having a contact screw 54, which, when the shutter is lifted sufficiently, abuts against a contact 55 on the crank cam 29, and thus makes the circuit of the electromagnet 18. The magnet attracts the armature 28, which lifts the arm 29, causing the lever 16 to be tilted to pull down the shutter, an insulating-screw 39 abutting against the arm 29 to separate the contacts 54, 55. The armature 28, through the rod 4, operates triggers 27, which operate two balls 44, one representing an advertisement disc, and the other a coloured disc, on two bagatelle-like board 19; the balls on their return down the inclined boards, are deflected by stops or pegs 20, so that it is a chance which of two channels 24 each ball will travel on returning to its first position. Each channel has a thin contact plate 46, which the ball presses on to a contact 47, thus energizing the electromagnets 18 to operate the corresponding disc, there being an electromagnet corresponding with each of the advertisement and coloured discs, which are connected with the armatures 38 of the electromagnets. The armatures 38 are held down by catches 35, until these are withdrawn by the lever 16 on again pulling down the shutter; the lever 16 has a crossbar 33 which operates the arms 31 of the catch device. Some of the parts may be operated mechanically instead of electrically, and the shutter may be dispensed with.
