(2.) In a heel-building machine, a lift-support, laterally movable clamps for embracing the lifts, a pivotally mounted arm, a head mounted on said arm capable of swinging therewith over the lifts contained between said clamps, and means movable with the arm for bringing said laterally movable clamps towards each other when the head is swung over the lifts. (3.) A heel-building machine having, in combination, a support for a plurality of heel-lifts, devices for centring the lifts upon said support, and means for sustaining said support, and centring-devices for simultaneous pivotal movement about an approximately horizontal axis into an inclined lift-receiving position. (4.) A heel-building machine having, in combination, a support for sustaining a plurality of lifts, devices for centring the lifts upon said support, mechanism for inserting nails in the lifts, and means for swinging said support and centring-devices about an approximately horizontal axis from operative relation to said mechanism into an inclined lift-receiving position. (5.) In a heel-building machine, in combination, lift-sustaining means comprising clamping-members arranged to receive the lifts of a heel between them, a presser-head mounted for tilting movement and arranged to be moved to and from a position in which it bears upon the said lifts, and means actuated by the movement of said presser-head for closing and positively opening the clamping-members. (6.) In a heel-building machine, in combination, a nail-supplying device, means for sustaining the lifts of a heel, a nail-driving mechanism mounted for angular movement, a presser-head mounted for tilting and vertical movement and arranged to be moved alternately to and from a position in which it bears upon the said lifts, and means operated by the movement of the presser-head to move the nail-driving mechanism to register alternately with the said nail-supplying device and the said sustaining-means for the lifts. (7.) In a heel-building machine, in combination, means for sustaining the lifts of a heel, a presser-head mounted for movement to and from a position in which it bears upon the lifts, a nail-supplying device, and a nail-driving mechanism arranged for movement with the presser-head to register alternately with the lift-sustaining means and the nail-supplying device.

No. 23912.—14th January, 1908.—JAMES BOND GROVE, of 34 Ghuznee Street, Wellington, New Zealand, Motor and Cycle Engineer. An improved tread-holder for pneumatic tires.*

Claims.—(1.) A holder for the tread of a tire, comprising a ring upon one side of the wheel to which the tread is attached by straps or the like, an inner concentric ring surrounding the hub of the wheel and attached to the first ring by spokes, and a ring upon the other side of the wheel to which the tread is attached by straps or the like, substantially as set forth. (2.) A holder for the tread of a tire, comprising rings upon each side of the wheel, straps or the like attaching the tread to the rings, inner concentric rings attached to the first rings by spokes, substantially as set forth. (3.) A holder for the tread of a tire, comprising rings upon each side of the wheel, straps attaching the tread to the rings, inner concentric rings attached to the first rings by spokes, the rings upon the inner side of the wheel being in two parts united by bolts or the like, substantially as set forth. (4.) The combination and arrangement of parts comprising the improved tread-holder for tires, substantially as and for the purposes set forth, and illustrated on the drawing.

No. 24242.—9th April, 1908.—WILLIAM PERCY ROUGH, of Abel Smith Street, Wellington, New Zealand, Metaphysician. Improved apparatus for the manufacture of carburetted air, and enriching same for lighting, heating, and power purposes.*

Extract from Specification.—The hydrocarbon liquid in the sealed feed-tank is delivered in small doses to a pipe from whence it can gravitate to the carburettor, wherein it meets a steady stream of air of a necessary proportional volume to gasify it. The carburetting of air at a lower temperature than the prevailing atmosphere is an important feature of the invention, insomuch as it eliminates possibility of condensation in the pipes leading to points of consumption. Another important feature of the invention consists in the enriching of the carburetted air to quality desired. The gas on leaving the gas-holder before entering the service-pipes passes through an enricher or second carburettor, which is not immersed in water, and receives its supply of hydrocarbon fluid from the sealed feed-tank by means of a pipe, to which is attached a regulator which regulates the supply of hydrocarbon liquid in quantities necessary to enrich the gas to quality desired by the adjustment of the regulator valve. Motive power is necessary for maintaining the apparatus in operation. This may be variously obtained, as by an electric motor or a gas-engine driven by the gas manufactured by the apparatus, or, when as little machinery as possible is desired, by the descent of a weight which is wound up at intervals as required by human labour. A wire cord, by which the motive-power weight is suspended, may be wound many times round a barrel or driving-drum, which is geared by means of a pawl to a ratchet-wheel keyed to the spindle of the blower-wheel. For the purpose of rewinding the motive-power weights the driving-drum is turned in the opposite direction to that in which the blower-wheel revolves, the pawl riding over the teeth of the ratchet-wheel, permitting the blower-wheel to remain stationary during the rewinding. The apparatus consists of a blower for forcing air into the carburettor, a sealed feed-tank for supplying the hydrocarbon fluid, the generator containing the carburettor and the gas-holder, and the additional carburettor or enricher, together with the necessary gearing and driving-power.

No. 24578.—10th July, 1907.—WILLIAM JOHN CARLIN DOWNEY, of South Perth, Western Australia, Australia, Law Clerk. Improved combined wind-gauge and vernier-elevator.

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

Extract from Specification.—In this invention the first chief feature consists in the means whereby the ladder with its sight-bar and vernier-elevator as a combined whole is made to traverse bodily across the barrel of the rifle, said movement being obtained by two milled wheels fixed to the ends of a screw-threaded spindle which interscrews into the seat-block on which the ladder slides, the whole being held on the ordinary bracket of the rifle. The second chief feature consists in the locking and unlocking means, whereby the vernier-elevator and sight-bar may be rapidly moved up and down the ladder, and without the use of the elevator-screw. The third main improvement consists in the employment of a rotatable orthoptic disc, which is secured to the top of the ladder, and formed with notches and openings to coincide with the back sight of the ladder.

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