JULY 13.] THE NEW ZEALAND GAZETTE. 2225

No. 29608.—25th May, 1911.—SYDNEY FREDERICK BUCKINGHAM, of Mangatainoka, Pahiatua, New Zealand, Labourer. An improved hose connection or coupling.

Extract from Specification.—Broadly speaking, the invention consists of a pair of claws, each of which is set opposite to the other, and each of which is articulated in one of the sections of the hose to be coupled. The claw is mounted in a recess in its own section of the hose-end, and when closed up to effect a joint it fits into a corresponding recess in the other section. A cam or eccentric lever is mounted in the other section of hose-end in such a way that when the said lever is turned so as to bear snugly against its own section of piping the cam tightens on the hook of the claw and prevents the claw from coming loose. The opposing claw is mounted in the other section, and its corresponding lever is similarly worked. In each hose-end is mounted a rubber ring or rings which take into a corresponding recess or recesses in the other hose-end to which it is to be joined. Pins on the hose-ends are placed oppositely to one another to facilitate fitting the ends together and to keep the ends in position when the joint is made.

(Specification, 3s. 3d.)

No. 29609.—9th June, 1910.†—JACOB WATKINSON and ALBERT EDWARD PAYNE, both of 138 Cambus Road, Canning Town, London E., England, Electricians. An improved apparatus for regulating or controlling the pressure of the current in an electric circuit.

Extract from Specification.—The invention consists in the combination with a series of resistances composed of separate pieces of graphite or similar material clamped together in groups and suitably connected to contacts, of a pivoted switch-arm carrying a roller or rollers or blocks mounted on resilient arms, which rollers or blocks are adapted to bear upon the contacts, and the said switch-arm may also be provided with flat spring arms to further insure an efficient contact.

No. 29651.—1st June, 1911.—STANLEY CARR, of Bowen Street, Chatswood, Sydney, New South Wales, Clerk. Improvements in laundry appliances.

Extract from Specification.—Means for removing clothes from laundry-boilers in which provision is made, by a peculiarly constructed holder, for retaining the clothes during the boiling operation in such positions that ebullition-cavities will be naturally created as the clothes are first placed in the holder, thus dispensing wholly with the necessity for disturbing the clothes with the stirrer, as is usually done. Means are also provided for securing the suspending parts of the holder in such a position as will insure their being undisturbed and always readily accessible for the attachment of the lifting and removing appliance, which in this invention is of a kind peculiarly adapted for the speedy transport of the holder with but a comparatively small expenditure of energy. The said holder is provided with a self-contained means for tipping it and emptying the contents into the laundry-tubs.
