Title: Improvements in or relating to Gasburners and the Method of Controlling the same
Inventor: LIDDLE EDWIN
Filed: 1903-06-15
Granted: 1903-07-23
Abstract: 13,342. Liddle, E., and Druiff, G. E. June 15. Incandescent gas burners; lighting; extinguishing.-Relates to gas burners, especially incandescent burners fitted with a bye-pass, and to arrangements for controlling the gas supply from various parts of a room or building, and for inter. changing the bye-pass and self-igniter where the latter is used. In one arrangement, the hole B in the plug is much larger on the side remote from the burner than on the side near the burner. Small openings G, H, on one side of the casing, supply the self-igniter and bye-pass respectively. Pipes 1, 2 lead to the self-igniter, a plug G<1> in the pipe 2 controlling the gas supply. An extension of the plug G<1> forms a second plug H<1> for controlling the gas supply to the bye-pass. The two plugs are operated by a thumb-piece H<2>. If the thumb-piece is vertical, gas passes to the selfigniter and not to the bye-pass, while when it is horizontal the reverse is the case. When it is placed at 45‹, both bye-pass and self-igniter are shut off. The main plug has a stop which, in its lowest position, indicates that the main passage is closed. When the thumb-piece H<2> is brought to its horizontal position, a pin in the plug H<1> moves a spring-controlled stop 4 into the path of the stop on the main plug, and so locks the plug in its "full on " position. In another arrangement, for use with overhead self-lighting devices, only one orifice H, Fig. 4, controlled by a plug H<1>, is arranged in the casing of the main plug. For controlling from a distance, a cord pulley a, Fig. 7, is secured to the end of the plug B. The cord can only turn the pulley in one direction, the spring e returning the plug to its original position. The cord is led over pulleys on the gas bracket and on the walls to the various positions from which it is desired to operate the plug. The ends of the cord are weighted, the total weight being equal to the pull of the spring. Thus when one or other of the cords is pulled, the plug turns in one direction, while on raising one or other of the weights, the spring turns the plug in the opposite direction. A metal piece g, engaging in a slot g<1>, keeps the small plug in place, while its ends g<3>, which is bent and bears on the end of the main plug, prevents the latter from binding. A thumbpiece h allows the plug to be actuated by hand at the bracket. The pulley and the part which connects it to the end of the plug may be so shaped as to enclose the spring between them.

When the amount of a purchase is struck on the keys before the rocking frames effect the ejection, longitudinal comb-like bars D, having different distributions of teeth d' for the keys to act on, and also forks d to guide the hangers, are shifted so that the corre- sponding hangers work clear of the corresponding ejectors. Some of the tubular change receptacles, as for instance that for halfpennies and one of two for pennies, are provided both with an ejector G', G', Fig. 2, for the lowest coin and with a ring ejector G<1>, G<3> for the next coin or two coins. The ejector G at the second pence receptacle has the thickness necessary for delivering threepence at a time. For delivering sixpences, there are two bottom ejectors G<5>, G<6> and a ring ejector G<0> which is only operated when they are both simultaneously actuated and so nip the tongue G<x>. When only one ejector is operated, the tongue acts as a brake on the other. The selections made by the comb- like bars are modified by notched bails E, E' which, acting through levers e, draw bolts e<3>, e<4>, Fig. 6, in certain ejectors to open a notch g<0> or let drop a hinged lug g<x>.

Filed: 1904-06-20
Granted: 1904-11-17
Abstract: 13,932. Stacks, H. R. June 20. Variable-speed gearing.-Upon both the driving and driven shafts B, C are mounted a pair of conical discs D, placed face to face and provided with flared grooves d to receive slats M. The hub of each disc is journalled within a collar E, preferably made in two parts and provided with a ring oiler. The collars are movable along the shaft so as to alter the distance apart of the discs, by means of levers F, F', which are pivoted to blocks g mounted on a tie-rod H. The blocks g are pressed inwards by means of springs arranged between the blocks and collars adjustably mounted on the rod H. A screw-rod K, mounted in brackets or frames I, engages nuts located in blocks L pivoted between the ends of the levers F, F<1>. Upon turning the rod K, by means of a hand-wheel, the ends of the levers F, F<1> are brought together or moved apart, thereby moving the discs D so as to increase the diameter of the drum, formed by the slats M, on one shaft and to diminish the diameter of the drum on the other shaft. An open belt, or belts, 0 passes over the drums to transmit motion between the shafts. To keep the slats in position when they are not in contact with the belts 0, a retaining-belt P is provided. This belt P passes around the drums and around idler pulleys Q, Q', S, S. The idler pulley S<1> is mounted on slides T fitted with bolts passing through the brackets I ; springs are interposed between the frame I and nuts on the bolts. By this means, the belt P is kept in tension. The springs acting on the fulcrum block g serve to keep the driving-belts in tension. Separate retaining- belts may be used for the drums instead of the one belt P. To prevent the slats from being tbrown out of the machine in case of the breakage of a belt or belts, a strap V is arranged over the discs, or rods on the discs may be threaded through the slats. The bearing-boxes for the various shafts, except the shaft of the idler S', are supported by set-screws, so that they can be adjusted to alter the tension of the belts, and the oil receptacles can be arranged underneath the boxes in whatever position the mechanism is fixed.

Abstract: 2337. Souza, A. E. de. Feb. 6. Aluminium hydrate and carbcnate.-Relates to the extraction of aluminium compounds from clay or other aluminous or aluminiferous silicates, for use in the production of aluminium or aluminium alloys. The material is treated with acid, preferably a mineral acid, and the solution, which contains the aluminium, is filtered or decanted off. The aluminium may then be precipitated by ammonium hydrate or ammonium carbonate. Or the solution may be treated with soda or potash for the cold precipitation of aluminium hydrate ; the solution may also be boiled, the resulting aluminates of potassium and sodium being soluble in excess of the reagents and in water, and the resulting solution treated as before with acids and ammonium hydrate. If the aluminium hydrate in the clay is free from iron, it may be extracted with sodium carbonate, the hydrate being reprecipitated from the sodium aluminate thus obtained by a current of carbon dioxide, or by hydrochloric acid and ammonium hydrate. If iron is present, it remains in an insoluble form when the clay is treated with sodium carbonate, and the sodium aluminate may be separated by filtration or decantatinn. The hydrate is dried in a steam-heated chamber, and is mixed with lime and treated by the electric arc in an electric furnace, the aluminium vapour being received in a special chamber having a refractory lining, where it is condensed in a reducing-atmosphere of carbon monoxide.
