Claims.—(1.) Means for automatically actuating the emergency brakes of tram-cars, the same consisting of connections between the fender or life-guard and the brake spindle or handle, by means of which the backward movement of such fender will actuate the brake-spindle. (2.) In means for automatically actuating the emergency brakes of tram-cars, the combination with a fender or life-guard pivoted at a short distance from its top, of a crank upon the brake-spindle, and a flexible connection between such crank and the top edge of the fender or life-guard, substantially as specified.

No. 24645.—11th July, 1908.—OSCAR JAMES SEEHAUSEN, of 930 North Halsted Avenue, Chicago, Illinois, United States of America, Gentleman. Improved apparatus for the generation of gas from liquid hydrocarbons.

Claims.—(1.) The combination of a generator, a casing therefor, consisting of an inner and an outer shell providing an air-space, the outer shell having openings for permitting a circulation of air through the said space. (2.) The combination of a generator, including a burner, a casing composed of an inner and an outer shell forming an air-space, a fuel-supply pipe passing through the casing to supply the generator, an air-supply pipe leading into the casing, and a service-pipe connected with the generator and passing out of the casing. (3.) The combination of a generator with a casing composed of an inner and outer shells, means for supporting the inner shell on and spacing it from the outer shell, and a door for the casing. (4.) In a generator, the combination of a vaporiser, a burner arranged to heat the same, a mixing-device, a plurality of by-passes leading from the mixing-device to the burner, and controllable means for varying the supply of mixture to the burner.

No. 24652.—13th July, 1908.—CHARLES GODFREY WHITAKER, Engineer, and VICTOR WHITLEY, Inventor, both of Christchurch, New Zealand. Improvement in the crates for carrying eggs.

Claim.—In egg-crates, spring or other elastic supports arranged on the inside of the crate and between it and the egg-carrying trays, substantially as specified, and for the purpose indicated.

No. 24711.—6th April, 1908.—FREDERICK SAMUEL GREER, of No. 7 Market Street, Sydney, New South Wales, Australia, Engineer. Improvements in the production of visible gas, specially useful for testing earth-pipes and rabbit-burrows.

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

Claims.—(1.) Improvements in the production of visible gas, consisting in bringing together muriatic-acid-laden air and ammonia-gas-laden air. (2.) Improvements in the production of visible gas, consisting in charging air with the fumes of muriatic acid and charging air with ammonia-gas and bringing the resultants together, substantially as described.

(Specification, 2s.)

No. 24908.—9th September, 1908.—FREDERICK WALTON, of 114 Holborn, London, England, Engineer. Improvements in or relating to road-vehicle-suspension arrangements.

Extract from Specification.—According to this invention, the springs employed are of the pneumatic-cushion type, but instead of obtaining the resiliency solely by the displacement of the air, and the variation in the air-pressure caused by the change in the cross-sectional shape of the cushion when subjected to a vibratory force, I employ air or other fluid confined under pressure in a flexible vessel or chamber for maintaining the same in a normal position, and utilise the resiliency occasioned by the resistance offered by such vessel or chamber to deflection or bending movement, or to any departure from its normal position, for enabling the vessel or chamber to act in the capacity of a pneumatic or fluid-pressure spring. By this means a wider range of action is obtained for taking up shocks or vibrations, a considerably lower pressure can be employed, whereby a softer and easier yielding movement is obtained, and a single fluid-pressure spring is capable of acting in the capacity of a deflection spring for absorbing all ordinary shocks and vibrations, and of a combined deflection and compression spring for absorbing abnormal shock or vibration. This effect has hitherto only been obtained by the employment of two sets of springs in the manner above set forth.

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