Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 21st December, 1904.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 17293.—26th November, 1903.—JOHN WISEMAN, of Auckland, New Zealand, Merchant. Improved means for locking window-sashes at any desired position.*

Extract from Specification.—The means devised consist broadly of a rack that is secured along one of the edges of each sash on its face adjacent to the pulley-stile. This rack extends throughout the whole height of the sash. Within the stile an eccentric cam is pivoted, such cam being provided with teeth on its face that engage with the teeth of the sash-rack. This cam is so pivoted that by its own weight it will lie in contact with the rack, and it is so shaped as to allow of the rack sliding freely past in one direction, but to prevent it sliding in the other.

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

No. 17440.—7th January, 1904.—CHARLES ROBERTSON, of 96, Russell Street, Dunedin, New Zealand, Carpenter. Improvements in laundry apparatus.*

Claims.—(1.) An apparatus for attachment to washing-tubs, substantially as described and shown in the drawings. (2.) In laundry apparatus, a rocking member composed of a plurality of downwardly extending arms, with means to attach the same, and means to allow the member to be rocked.

No. 17559.—23rd February, 1904.—GEORGE GRANVILLE SUTHERLAND and ALEXANDER GORE BRETT, both of Hawera, New Zealand, Commission Agents. An improved moustache-guard for spoons.*

Claims.—(1.) A moustache-guard for spoons, the same consisting of a plate with inwardly curved edges adapted to overlie the bowl of the spoon, and provided with downwardly extending clips at one end adapted to be passed on to the spoon-handle and to engage beneath it, and with a spring clip at the other end adapted to grip upon the under-surface of the spoon-bowl, substantially as specified. (2.) The moustache-guard for spoons, substantially as described and explained, and as illustrated in the drawings.

(Specification, 2s. 3d.; drawing, 1s.)

No. 17579.—26th February, 1904.—THOMAS PATRICK LYONS, of Wellington, New Zealand, Carriage-proprietor. Improvements in or relating to the tires of vehicle-wheels.*

(Specification, 2s.; drawing, 1s.)

No. 17581.—27th February, 1904.—HERBERT JAMES WHITELAW, of Palmerston North, New Zealand, Saddler. An improved clothes-peg.*

Claim.—A clothes-peg made of one piece of metal, and comprising a central loop, sides formed by doubling the ends of the loop upon themselves, the sides being continued above the loop until they meet and form a second loop, and having their extremities flared outwardly, substantially as set forth.

(Specification, 1s. 6d.; drawing, 1s.)

No. 17595.—1st March, 1904.—GEORGE HENRY CLAPHAM and JOHN LAUNCELOT BARLOW, both of Wellington, New Zealand, Metal-workers. Improved dies for use in the manufacture of cake-tins and the like.*

Claims.—(1.) Dies for the manufacture of cake-tins, patty-pans, and the like, formed with working or moulding surfaces of sheet metal and with bodies of a solid metal surrounding the back faces thereof, substantially as specified. (2.) In the construction of dies for the manufacture of cake-tins, patty-pans, and the like, wearing or moulding faces of sheet metal bent into the desired shapes and bodies formed of solid metal moulded around the back faces of the sheet metal while in a molten state, substantially as specified.

(Specification, 2s. 6d.; drawing, 1s.)

No. 17600.—2nd March, 1904.—HENRY RENNER CASSEL, of 3, Princes Street, London, England, formerly of 135, Westbourne Terrace, London aforesaid, Metallurgist. An improved process and apparatus for filtering slimes and extracting values therefrom.*

Extract from Specification.—The operation is as follows: The door i being in place, and the cock m¹ closed, pulp is run into the tank A to constantly submerge the cells B. The cock n² is then opened, and the suction-pump e is started to draw the liquid from the pulp into the cells B, whence it is carried to the solution-tank. In order to prevent the settling of the pulp at the bottom of the tank A, and to provide a circulation of the pulp between the cells, the centrifugal pump k is also set in motion. This will cause the pulp to be withdrawn from the bottom of the tank A through the discharge-door, and to be delivered to the tank at the top above cells B, through the nozzle n¹, or pipes n⁶, thereby establishing a perfect circulation which is essential to the formation of homogeneous cakes. During this operation the pulp gradually thickens against the filter-cells, and additional pulp is supplied to the tank to keep the cells B always submerged. When a layer of sufficient thickness has accumulated on the cells, the valve n² is closed, and valve m¹ opened, whereby the non-adhering pulp is temporarily lifted into the pulp-storage tank g. During this operation suction in the cells B is maintained to prevent portions of the cakes from becoming detached. After the non-adhering pulp has thus been removed, the valve h² is opened to admit water into the tank A to wash out and displace the values still contained in the cakes. These values will by pump e be drawn into cells B. The wash-water may be taken from any source. When the values have been extracted the valve h² is closed, and the water is returned from tank A through pump k into tank h. The pump k is now stopped, the coupling j¹ is disconnected, and the door i is lowered on to the track l² and drawn by suitable means along the track away from the tank. A car r is then pushed under the tank (Fig. 2), and pump e is stopped. The detachers o, or q, are next set in motion to detach the cakes from the cells B, and cause the detached fragments to fall into the car r. If desired, the loosening of the cakes from the cells may be effected by pumping air into the latter.

No. 17606.—1st March, 1904.—EDWARD SMETHURST, of Christchurch, New Zealand, Engineer. Improved means for controlling the speed of screw-propelled ships.*

Extract from Specification.—The special means I employ for effecting the purpose of my invention is a pair of rudders, coaxially mounted, and mechanism for operating the same. The said mechanism is such that the rudders may be normally locked together, but it will be possible for the rudders to be opened out so as to lie athwart the propeller. When the rudders are in this position, the water displaced by the revolving screw will be prevented from escaping rearwards of the ship, the forward motion of which will, under the circumstances, gradually cease. If the rudders are moved so as to form with each other an obtuse angle or concavity next the propeller, the displaced water will not only be prevented from escaping rearwards, but will be deflected forwards in the direction of the ship’s motion.

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

No. 17607.—27th February, 1904.—JAMES GEMMELL, of Incholme, Maheno, New Zealand, Farmer. Apparatus for stacking hay, straw, and the like.*

Claims.—(1.) The general construction, arrangement, and combination of parts composing my apparatus for stacking hay, straw, and the like, all substantially as and for the purposes described. (2.) In apparatus such as described, the combination and arrangement of parts for operating the forks, substantially as described, and illustrated in Fig. 2 of the drawings. (3.) In apparatus such as described, means for operating the prongs so as to alter their inclination to each other, substantially as described, and illustrated in Fig. 3 of the drawings.
