No. 18511.—29th September, 1904.—WILLIAM PERCIVAL CONOLLY, of Oxford Chambers, Bourke Street, Melbourne, Victoria, Australia, Architect. Safety appliances to prevent dangerous accidents in the shafts or wells of passenger and goods elevators.

———

Claims.—(1.) A safety appliance consisting essentially in a number of movable frames suspended by chains or the like means above or below or both above and below the lift, cage, or elevator, and so arranged that as the lift, cage, or elevator arrives at any one floor a frame rises or falls respectively to the level of each of the other floors of the shaft or well, substantially as and for the purposes set forth. (2.) A safety appliance embodying in combination a set of frames as A, chains or the like as F by which the frames are suspended, trays as G and H for receiving the frames and chains, and means for connecting the chains to the frames, top of shaft, bottom of lift cage, and to the trays, substantially as and for the purposes set forth. (3.) In safety appliances, a frame as A constructed of a staunch rim as A¹, and having its interior filled across with netting or the like, said filling being provided with an opening or openings for the haulage-rope, ropes, or piston to pass through during the working of the said lift, cage, or elevator, substantially as and for the purposes set forth.

No. 18512.—28th September, 1904.—HEINRICH BECK, of 7, Leipzigerstrasse Meiningen, Germany, Engineer. Improvements in electric arc lamps.

———

Extract from Specification.—The advantages of my electric arc lamp for continuous current as well as for alternating current are based upon a new principle for regulating the feed of the electrodes. This principle is characterized by one or both electrodes resting laterally upon a support with its extreme ends, the ends which constitute the supporting-points of the electrodes being gradually consumed by the heat of the arc light, so that the electrodes will descend in a perfectly uniform manner. The lateral edge of the electrode, the end of which rests upon a suitable support, consists in my invention of carbon, or of some material which is converted into carbon by combustion, and which shows a similar behaviour. The lateral edge, the extreme end of which constitutes the resting-point of the electrode, may consist of a special narrow ridge of carbon or the like, which is laterally attached to the electrode, or it may be formed by shaping the electrode itself correspondingly. It is essential in my invention that the electrode with lateral supporting ridge, the extreme end of which rests upon a support, is pointed and hollowed out at the side which faces the arc light in such a manner that a lateral starting or supporting point, so to speak, is provided for the arc light, whereby a quiet burning of the electric arc is produced in the new lamp. The lateral supporting ridge may be provided on both electrodes, but it is also sufficient to have the positive electrode only resting with the end of its outer edge upon a support, and then securing the uniform feed of both electrodes by suitably coupling the electrodes with each other. In order to protect the electrodes against the lower parts of the supporting edges burning out laterally, this part of the electrodes in a modification of my invention is provided with a device for limiting the supply of air—a sleeve or the like, for instance, preferably made of metal, and being of sufficient size and presenting a sufficient cooling surface for transmitting the heat resulting from the electrode to the air without becoming incandescent itself. Inasmuch as the supporting edges are made of carbon or the like, a perfectly uniform combustion or evaporation of the pointed end of the supporting ridges is produced by the electric arc; nor is there any disturbance of the arc or coloration of the same by material dripping down from the supporting ridges. For the purpose of operating and for cutting out electric arc lamps of this kind, igniting and extinguishing devices of most simple construction may be employed.

No. 18515.—24th September, 1904.—BARBARA JOANNA MOUAT, of South Dunedin Post-office, New Zealand, Postmistress. Improvement in draught-regulating for grates and ranges.

———

Claims.—(1.) In the bottom bars of grates or ranges, in combination with same, a box-like projection formed of bars or openings for increasing the draught and bringing the fire towards the front, with a damper for regulating or shutting off the draught as needed, substantially as set forth. (2.) In combination with the fire-bars of a grate or range, a damper furnished with a valve and a box-like projection, arranged so as to control the draught to the fire-bars and said projection, all substantially as set forth, and as shown in the drawing. (3.) A damper placed immediately under the fire-bars of a grate or range to control the draught admitted to same, substantially as set forth.

No. 18517.—24th September, 1904.—HENRY UPTON ALCOCK, of 208-212, Russell Street, Melbourne, Victoria, Australia, Billiard-table Manufacturer. Improvements in convertible and other billiard-tables.

———

Claims.—(1.) In convertible billiard-tables, adjustable props or supports as A hinged to cross-rails as B¹ and combined with springs as A¹, substantially as described and shown. (2.) In convertible billiard-tables, levers as E, e, e¹, capable of being fulcrummed in the end rails B at E¹, lifting the table, and of being supported on a longitudinal shelf E² under the table when not in use, substantially as described and shown. (3.) In convertible billiard-tables, in combination, the adjustable hinged props or supports A, springs A¹, guide-pins D, levers E, and shelf E² arranged and assembled on the legged frame and table, substantially as described and shown. (4.) In convertible billiard-tables, the screwed props A fitted in blocks on under-side of table combined with cross-rails as B¹ and guides as D fitting in slots in the legged frame, substantially as described and shown. (5.) In convertible billiard-tables, the levers E, e, e², having hinged part e³ and fulcrummed in the recess in end rails, combined with the pivoted temporary props a¹ and guides as D, substantially as described and shown. (6.) In convertible billiard-tables, in combination, screwed props as A, rails as B¹, levers as E, and guides as D arranged and assembled on the legged frame and table, substantially as described and shown. (7.) In billiard-tables, the cushion-rails built up in wood sections, as C¹, C³, and C⁴ about an angle-iron bar F, all assembled and secured substantially as described and shown. (8.) In billiard-tables having the cushion-rail built up in sections, securing the facing C¹ in either manner substantially as described and shown.

No. 18529.—27th September, 1904.—PETER CAMPBELL, of 52, Page Street, Albert Park, Victoria, Australia, Moulder. An improved pipe-moulding machine.

———

Extract from Specification.—With my invention the placing of a half-pattern within a half-box, the entrance of the sand therein, and the ramming of the said sand is performed by a machine. In this the pattern rotates in a holder which rotates and to which holder the half-box is affixed. The half-box only travels through half a circle (more or less), whilst the pattern has two motions, one around its own axis and the other around with its holder. Each half-box is treated in the same manner, and then one placed on the top of the other and a complete box and mould thus formed.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 18530.—27th September, 1904.—JABEZ ADAMS, of “Glenmire,” Thomson Street, Constable, and CHARLES ALFRED CROSS, of Brown Street, Plumber, both of Hamilton, Dundas, Victoria, Australia. An improved pipe-wrench.

———

Extract from Specification.—The cycle of operations with our invention is as follows: The jaws of the stationary and U-sectioned handles are separated so that they will encompass the article to be locked. The U-sectioned handle is then pushed towards the said article till its jaw touches the same. The pawl-catch then falls into one of the serrations on the stationary handle. The U-sectioned handle is then pulled towards the stationary handle, and a vice-like grip is conveyed to the article. In the modification the action is the same, save that the finger-hold M has not to be pulled outwardly when the U-sectioned handle requires to be drawn from the stationary handle.
