No. 22519.—6th March, 1907.—Thomas Bowrey and John Bowrey, of No. 359 Pitt Street, Sydney, New South Wales, Australia, Scale-makers. An improved automatic weighing-machine for grading sheep and other like purposes.*

Claims.—(1) In an improved automatic weighing-machine for grading sheep and other like purposes, the use of a dial bearing two sets of figures, so that when the carcase of a sheep is weighed the indicator or hand on the dial will point both to the gross weight ascertained and calculate the decrease customarily allowed for the cooling of the body, substantially as described; (2) the attachment of a rod from the overhead machine, as ordinarily made, running down to and connected to that end of the beam furthest from the dial end; and (3) the fixing of an air-valve underneath the beam at the dial end which will so operate as to cause the indicator or hand on the dial to remain motionless on the mark of the weight ascertained, and there remain steady until the load is removed, substantially as described.

No. 22747.—29th April, 1907.—George Richard Hale, of Napier, New Zealand. Improvements in scaffolding-brackets.*

Claims.—(1.) A scaffolding-bracket, comprised by a horizontal member having an eye with springy sides at its inner end and a bolt passing across the eyes, a diagonal member pivoted at its upper end to the outer end of the horizontal member and formed with a vertically extending portion beyond the pivot, and a stop-piece upon the horizontal member with which the vertical portion of the diagonal member engages when turned on its pivot, substantially as specified: (2.) In scaffolding-brackets, a horizontal member provided with an eye at its inner end, having springy sides, and adapted to fit on to a wall-hook, and a bolt passing across the eye, provided with a thumb-nut on its end, by means of which the sides of the eye may be caused to grip the hook, substantially as specified. (3.) In scaffolding-brackets, a horizontal member and a diagonal member pivoted at its upper end to the outer end of the horizontal member and having a vertical extension beyond the pivot point, and a stop-piece upon the horizontal member with which such extension engages when the two members are turned outward on their pivot joint, substantially as specified. (4.) The general arrangement, construction, and combination of parts in my improvements in scaffolding-brackets, substantially as described and explained, and for the several purposes set forth.

No. 22882.—20th May, 1907.—Thomas Edgar Carter, of 88 Victoria Street, Auckland, New Zealand, Music-teacher. Improvements in window-sash lifting and locking appliances.*

Extract from Specification.—The means devised consist in the use of a tooth pinion mounted in the pulley-stile of the window and gearing with the teeth of a rack extending along the adjacent edge of the window-sash. The pinion is mounted on a spindle projecting into the room, and is operated by a handle secured upon its end. Combined with the rack are antifriction rollers, which are mounted therein and run on the face of the pulley-stile. On the other edge of the sash a similar roller is mounted at the bottom and at the top end, and combined with each roller is a flat spring that bears against the face of the adjacent pulley-stile. Special means are provided whereby the pinion-spindle may be prevented from turning, so that the sash may be held at any height, and locked from being further opened or closed from the outside.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 23129.—12th July, 1907.—Frederick Hurston Frankland, of Wellington, New Zealand, Indent Agent. An improved system of disinfecting water-closets and the like.

Claim.—The improved means for disinfecting water-closets and the like, the same consisting of a jar composed of porous material and adapted to fit within the water tank or cistern, and having the required disinfecting-material sealed therein, substantially as specified.

(Specification, 1s. 9d.)

No. 23203.—25th July, 1907.—Albert John Fortescue, of Arncliffe, near Sydney, New South Wales, Australia, Manufacturer. Improvements in devices for connecting the ends of metal tires for vehicle-wheels.

Claims.—(1.) In devices for connecting the ends of vehicle-wheel tires, the combination with one end of a tire of a connecting-plate riveted or otherwise secured thereto, a recess in the rim to receive said connecting-plate, and a pin through said rim, connecting-plate, and opposite end of the tire, substantially as described and explained. (2.) In devices for connecting the ends of vehicle-wheel tires, the combination with one end of a tire of a connecting-plate riveted or otherwise secured thereto, a recess in the rim to receive said connecting-plate, a pin through said rim, connecting-plate, and opposite end of the tire, a felloe-plate retaining said pin in position, and a bolt or bolts securing said felloe-plate, the rim, connecting-plate, and tire together, substantially as described and illustrated.

No. 23337.—13th June, 1907.—Alfred Harris Warmsley, of “Avondale,” Ilford Lane, Ilford, Essex, England, Engineer. Improvements in apparatus for producing combustible gas from petrol or other spirit or oil.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) In apparatus of the kind set forth, comprising an air-blower, an engine for working the blower, a carburettor, a valve device for supplying petrol or spirit to the carburettor, and a gasometer, a valve or valves controlling the admission of air to the carburettor, the said valve or valves being operatively connected with the movable gas bell or holder, and constructed or arranged so that when the bell has risen to a predetermined height, or to its uppermost working-position, the supply of air to the carburettor is automatically shut off, and remains so until the bell has fallen to a predetermined extent, or to the lowermost working-position, when the supply of air is again automatically admitted to the carburettor and generation of gas again commences, substantially as and for the purposes described. (2.) In apparatus of the kind set forth, a valve for controlling the air-intake of a blowing-engine, the said valve being operatively connected with the movable gas bell or holder and so arranged as to be automatically actuated to close the said air-intake by the combined actions of the moving gas-bell and the suction in the air-intake caused by the action of the blower, to be held on its seat by the suction and to be moved off its seat again by the moving gas-bell, substantially as and for the purposes set forth. (3.) In apparatus of the kind set forth, the combination of the balanced suction-valve for opening and closing the inlet of air to the blower, the rotary valve in the main air-pipe for opening and closing the main air-supply pipe, and means for operating the said valves by the movements of the gas bell or holder, substantially as described and shown. (4.) In apparatus of the kind set forth, a valve in the main gas-supply pipe, the said valve being operatively connected with the movable gas bell or holder so that when the bell falls to an abnormally low position the valve is automatically actuated so as to shut off communication between the main gas-supply pipe and the gasometer or bell, substantially as and for the purposes set forth. (5.) In apparatus of the kind set forth in claim 4, the combination with the valve of a weighted connection thereto, a weighted cross-bar or lever for normally holding the valve open, and an attachment on the movable gas holder or bell adapted to actuate the said lever so as to release the valve and allow it to close by its weight, all arranged and operating substantially as and for the purposes described with reference to the drawings. (6.) The parts of the apparatus for producing or generating gas from petrol, spirit, or the like, constructed, combined, and operating substantially as described with reference to the drawings and for the purposes set forth.
