Claims.—(1.) Improved rail-joint for railways, consisting of abutting rails each having its end formed doubly diagonally with the tread and the web (with base) at opposite angles, and ordinary fish-fastenings or the like, substantially as described and explained. (2.) A rail having parallel doubly diagonal ends, substantially as described and explained.

No. 25855.—21st April, 1909.—GEORGE LEWIS, of Wellesley Road, Napier, New Zealand, Plasterer. An improved method of joining plaster slabs.

Claim.—The improved method of joining plaster slabs, consisting in forming the adjacent edges of the slabs with dovetailed rebates, so as to constitute a dovetail recess between them, and in filling such recess with plaster in which a strip of scrim or like material is imbedded in such a manner as to extend across the joint, substantially as specified.

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

No. 25856.—14th August, 1908.—ERNEST CLARK, of “Brooklyn,” Pearl Street, Northcote, Victoria, Australia, formerly of 35 James Street, Windsor, Victoria, Manager. An improved method of, and apparatus for, retreading and repairing the covers of pneumatic tires.

[NOTE.—This is an application under the International and Intercolonial Arrangements, the date given being the official date of the application in Australia.]

Extract from Specification.—My improved method consists in preparing strips of rubber dough of a suitable length and variable widths. These strips are moistened by the application of benzine, naphtha, or the like, and then pressed together with the widest strips at the bottom and the narrowest at the top. The rubber dough, prepared as above described, is placed on a section of the tire to be repaired, which tire has been previously cleaned, and the section is then placed in an apparatus devised for shaping, pressing, and vulcanising the prepared rubber to the outer surfaces of the tire-covering.

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

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

No. 25872.—27th April, 1909.—JAMES HODGKINSON, of 4 Halton Bank, Eccles Old Road, Pendleton, Manchester, England, Engineer. Improvements in and connected with apparatus for use in evaporating liquid from brine for the production of salt, or for evaporating liquid from other solutions.

Extract from Specification.—I take steps for constant feeding or charging of fuel to the fire or fires, and I use such a stoker as the Hodgkinson or like stoker, in which the fuel is fed by rams elevated above the fire-doors against an elevated or top coking-plate, which serves to evenly feed the fuel upon a dead-plate forming a coking-bed below the door and immediately above reciprocating fire-bars. The reciprocating fire-bars are self-cleaning, and the fuel is taken from the bottom of the coking-bed, and as it is consumed is traversed from the front to and over the back of the furnace-grate, and the furnace-doors are never opened during evaporation, and thus the temperature will only vary a degree or two if the stoker has proper attention. I take steps to prevent interior incrustation, the appliance used for this purpose also sweeping the product to an outlet, from which it is mechanically lifted, and I also agitate the liquid to assist evaporation, and to break up any surface film. The entire heat both of steam and furnace gases, due to the working of the main or other pan, is or may be beneficially utilised to impart heat to brine in auxiliary or successive pans, or to heat a supply of brine for passage to the evaporating pan or pans. The steam produced in one pan is superheated by the furnace gases when being utilised to heat an auxiliary pan.

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

(Specification, 10s.; drawing, 5s.)

No. 25873.—27th April, 1909.—THOMAS CLAUD DURHAM, of 111 Fifth Avenue, New York, United States of America, Gentleman. Improvements in razors.

Claims.—(1.) In a razor, the combination with a blade, of a co-operating safety-guard lying beyond the edge of the blade, substantially as described.

[NOTE.—Here follow eight other claims.]
