No. 27879.—10th June, 1910.—OLAVE TAPP, of 61 Main Street, Palmerston North, New Zealand, Engine-fitter. A vacuum pump which can be driven by means of a belt, or by fixing a steam-cylinder to make it a combined engine and pump on the same base.*

Extract from Specification.—This invention relates to vacuum pumps that have a piston rotated by means of a connecting-rod striding the cylinder coupled to a crosshead sliding on a round guide. The air-inlet valves are cup-shape, held in position by means of a spiral spring. The air-outlet valves are flat, sliding on a square stud held against the cylinder-face by means of a spiral spring. The steam-cylinder mounted on four standards fixed to the air-cylinder and the piston-rod bolted to the crosshead make it a combine steam engine and pump. By removing the steam-cylinder, four standards, uncoupling the piston-rod, and removing the eccentric, can be used as a belt-driven pump.

No. 28613.—20th October, 1910.—RONALD JOHN LIVINGSTONE HILDYARD, of 103–105 Queen’s Bridge Street, South Melbourne, Victoria, Australia, Engineer. An improved process or method for the manufacture of steel or metal wheels.

Claim.—An improved method or process of making wrought steel or iron wheels in which the wrought spokes having been first riveted to the tire, the said wrought steel or iron tire is then heated by means of a heating apparatus and made hot so as to expand it; that while being in this state of expansion the inner ends of the spokes are placed in a suitable mould, and cast metal is poured into same to form the hub or centre; that so soon as the molten metal is run into the mould to form the hub the tire is allowed to cool off, and so simultaneously contracts with the contraction caused by the cooling-off of the molten hub or centre, and thus overcomes the excessive strain.

No. 28976.—11th January, 1911.—WILLIAM FLOOD, of 49 Edgeware Road, Enmore, near Sydney, New South Wales, Australia, Engineer. An automatic reversible stop and lock for doors, gates, and the like.

Extract from Specification.—I provide a door-stop screwed to the floor, having two shoulders (aa′) against which the door strikes; this stop is fixed to the floor in operative position, when the door (d) is opened it strikes the stop at shoulder (a), causing the said stop to turn on screw outward, thus allowing door to pass beyond the shoulder (a) to the shoulder (a′), which it strikes; this causes said stop to revolve to its normal position, the door being held between the shoulders (aa′), forming a lock, and kept in an open position till released, which is done by turning shoulder (a) outward.
