No. 19240.—23rd March, 1905.—ARTHUR APPLETON STEPHENSON, of Perth, Western Australia, Gas-engineer. Oil-fuel vapouriser for production of light and heat.*

Extract from Specification.—A is the oil-cistern provided with a pump not shown whereby pressure is obtained. The oil under pressure passes up through pipe a₁, which is connected at a₂ to the cistern, and said pipe proceeds as shown into the tubular chamber b, which is suitably connected to the cistern as at a₁. This chamber is provided with a nipple b₂ at its highest part, through which the vapourised oil passes into another and upper chamber. The chamber b is formed with a flange b₃ and a gallery b₄, said gallery having perforations b₅, whose purposes will hereafter be explained. The tubular chamber c is placed over the nipple b₂, and is formed with a foot flange as c₁ having small holes c₂. Four open-mouthed pipes as c₃ are attached to the chamber c for the supply of air at a normal pressure, said chamber terminates in a conical top and pipe c₄, through which the vapourised oil and air from pipes c₃ passes after being mixed together within the chamber c. The vapour upon issuing from pipe c₄ enters the outer chamber d and strikes against the baffles c₁, which are of fine wire gauze. These baffles cause a certain or surplus amount of vapour to descend and pass through the small by-pass perforations b₅ and c₂ above referred to, where it is ignited at e and acts as the heating or vapourising agent for the appliance as a whole by maintaining it in a heated condition. The holes c₂ are small so as to act as a check on the escape of the surplus vapour. An incandescent mantle may be attached to the chamber for production of light, or the vapouriser used as a burner for heating purposes.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19252.—24th March, 1905.—PETER ELLIS, of Kilbirnie, Wellington, New Zealand, Engineer. An improved motor.*

Claims.—(1.) A motor comprising, in combination, a drum having a series of radially formed cylinders, pistons for each of said cylinders, a casing of larger circumference receiving said drum, and an axle upon which the drum is revolvably mounted, said axle having motive fluid and exhaust passages, each cylinder having a port giving communication with said motive fluid and exhaust passages in the spindle alternately, substantially as specified and illustrated. (2.) A motor comprising, in combination, a drum having a series of radially formed cylinders, pistons for each of said cylinders, a casing of larger circumference receiving said drum, and an axle upon which the drum is revolvably mounted, said axle having motive fluid and exhaust passages, each cylinder having a port giving communication with said motive fluid and exhaust passages in the spindle alternately, and a pulley in adjustable contact with the periphery of said casing adapted by frictional contact to cause the drum and casing to revolve, substantially as specified and illustrated. (3.) In a motor of the type indicated, a drum having a series of radial cylinders fitted with pistons, a casing receiving said drum, a spindle upon which said drum is mounted having passages for the admission and exhaust of motive fluid from said cylinders, the drum and the casing revolving in the same direction, substantially as specified and illustrated. (4.) In a motor of the type indicated, a drum revolvable upon an axle, said axle having passages for the admission and exhaust of motive fluid to and from the cylinders radially arranged in regard to said drum, substantially as specified and illustrated. (5.) A motor consisting of the parts constructed, combined, and operating substantially as specified, and as illustrated in the drawing.

No. 19441.—6th May, 1905.—DAVID MCKENZIE, of Tennyson Street, Grey Lynn, Auckland, New Zealand, Cabinet-maker. An easy chair.*

Claims.—(1.) In an easy chair, two horizontal spiral-tension springs, each with one end attached to the respective front uprights of the arm-rests of the chair, and the other ends being led through a hole or slot in the respective back upright and attached to the back frame of the chair, and which is suitably hinged at its base to a plate on the upper frame of the chair for the purpose above set forth, substantially as described and as illustrated in the drawings. (2.) In an easy chair, the arrangement, construction, and combination of a lower frame mounted on roller-casters pivotedly supporting an upper frame held apart and together by springs and strappings with two strong spiral-expansion springs suitably placed in front of the centre of the sides of the frames, said upper frame carrying arm-rests with front and back supports, and also a back plate with a back frame hinged thereto with two spiral-tension springs attached thereto, the other ends of such spiral-tension springs being attached at the back of the respective back-supports to the said upper frame, and two horizontal spiral-tension springs, each with one end attached to its respective front arm-rest support, and the other running through the back-support and attached to the back frame, all for the purposes above set forth, substantially as described and as illustrated in the drawings.
