No. 24546.—20th June, 1908.—FRANK COOPER, of Christchurch, New Zealand, Implement-manufacturer. An improved shackle for bridle of ploughs and similar implements.

Claim.—A shackle for bridle made to engage bridle top and bottom, having a bolt or stop to permanently hold shackle to bridle in combination with a pin, and further holes to engage holes in bridle to regulate position, substantially as and for the purposes described, and substantially as shown in drawings.

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

No. 24547.—22nd June, 1908.—HENRY JAMES TOPLISS, of Christchurch, New Zealand, Engineer. Improvements in or relating to the covers or lids of churns.

Extract from Specification.—The means devised consist broadly in the use of a cover that fits within the opening, and is held in position by means of a number of arms radiating from and hinged to a block mounted upon a central pin, and the outer ends of which arms are adapted to clip beneath a flange surrounding the opening upon the churn, and to be forced into engagement therewith, so as to press the cover hard upon its seat, by means of a nut screwed upon the outer end of the central pin. A carrying-arm is mounted upon the churn frame, and is adapted to support the cover and to swing it into or out of the churn-opening as required.

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

(Specification, 4s. 6d.; drawing, 1s.)

No. 24549.—23rd June, 1908.—HENRY JAMES TOPLISS, of Christchurch, New Zealand, Engineer. An improved machine for packing bulk butter into boxes or like receptacles.

Extract from Specification.—The machine designed comprises a vertically moving ram or plunger mounted above a table on which is placed a casing to hold the box, and combined with which is a hopper. The casing and hopper are adapted to be moved beneath the ram, which, descending into them, will force the butter (the desired quantity of which has been previously placed within the hopper) out of the hopper into the box contained in the casing. The ram then rises and completes its movement, and the casing may be moved from beneath it and the filled box removed.

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

No. 24552.—24th June, 1908.—WALTER JAMES MALDEN, Agriculturalist, and ARTHUR MALDEN, Engineer, both of “Avalon,” Cranes Park, Surbiton, England. Improvement in the treatment of tars and pitches in order to render them more suitable for industrial purposes.

Claims.—(1.) A process for treating tar with peroxide of manganese and sulphuric acid for the purpose stated, in which the tar is liquified by heat and the manganese and acid added, the temperature of the tar being preferably such as to prevent the evaporation of the volatile oils, the temperature being afterwards raised to a point calculated to produce the desired result or maintained at a lower temperature until such result is obtained. (2.) A process for treating tar with peroxide of manganese and acid for the purpose stated, in which the tar is heated to a temperature ranging up to 148° C. or such a degree above this point as will permit the acid to

be added by the operator with safety, and manganese and sulphuric acid added, the temperature being afterwards raised to a point calculated to produce the desired result or maintained at a lower temperature until such result is obtained. (3.) A process for treating tar with peroxide of manganese and sulphuric acid, in which the tar is first heated until sufficiently fluid and peroxide of manganese and sulphuric acid added in the proportion as 2 is to 1, and then raising the temperature to the desired point and maintaining the temperature until the loss by evaporation equals a known amount in a given space of time. (4.) In a process for treating tars, the addition to the heated liquid tar of 10 per cent. of manganese peroxide, and the temperature of the tar being raised to 50° or 60° C., 5 per cent. of sulphuric acid, the temperature afterwards being raised to 180° C. and maintained until the evaporation is equal to about 1/40 of each 100 parts employed in the last fifteen minutes of the treatment, the mass then being allowed to cool. (5.) A process for treating pitches in which oil or tar is added to heated fluid pitch, or both oil and tar added thereto, the pitch being afterwards treated with manganese peroxide and sulphuric acid in the proportions specified, and in the manner and for the purpose stated.

(Specification, 8s.)

No. 24556.—25th June, 1908.—THOMAS YABSLEY, of Coraki, Richmond River, New South Wales, Australia, Grazier (assignee of Frank Russell, of Spring Street, Sydney, New South Wales, Australia, Publisher). Improvements in stock and farm gates.

Extract from Specification.—According to this invention a vertically swinging collapsible-bar gate is supported on a hanging-post by means of one horizontal pin. A housing, by which the gate when open and collapsed is covered and protected, is associated with the hanging-post. The weight of the gate is counterbalanced by means of a vertical-falling weight which works over a pulley above the hanging-post, and is connected by a flexible line to the top bar of the gate.

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

(Specification, 4s.; drawing, 1s.)

No. 24559.—25th June, 1908.—JOHN LAVERY, of Waubra, Victoria, Australia, Farmer. Improvements in disc ploughs and cultivators.

Extract from Specification.—I accomplish the object of my invention by mounting the rear wheel upon an arm hinged to the framework at the back, with means for adjusting its position laterally. The rearwardly extending arm is also provided with an extension which projects from the hinge upon the near side of the plough, and is provided at its outer end with a connecting-rod attached to a hand-lever having a spring catch and quadrant so that it may be locked in position. Thus, by removing and adjusting this hand-lever, the rearwardly extending arm carrying the rear wheel is adjusted as a bell-crank lever, and the position of the rear wheel with relation to the frame correspondingly altered. The near side wheel is mounted on the outer end of this side extension of the hinged arm with a suitable spring-catch lever for adjusting its height and correspondingly the lateral set of the plough.

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

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

No. 24565.—23rd June, 1908.—RECKITT AND SONS, LIMITED, of Hull, York, England, Manufacturers (assignees of Thomas Robinson Ferens, M.P., of Wilton House, Hull, York, England). Improvements relating to sprinklers for liquids.

Claims.—(1.) A sprinkler, comprising a screw-threaded neck or nozzle provided with a central filling aperture adapted to be closed by an elastic cover or plug, the flange around the said aperture being formed with a hole or perforation through which the liquid is sprinkled, and being also adapted to effect the return to the receptacle of any liquid deposited thereon after sprinkling, substantially as described, for the purposes specified. (2.) A sprinkler having its parts constructed and arranged substantially as described with reference to the drawings, for the purposes specified.

(Specification, 3s. 9d.; drawing, 1s.)
