Extract from Specification. — Our invention relates to improvements in brush-holders for electric machines, and the object of the invention is to devise a holder which will not allow the brush to stick in the holder, and whereby the brushes will be in a proper commutating position no matter how much they may wear, and it consists essentially of brush-holding arms moving parallel to the commutating plane, and bearings therefor disposed substantially at right angles to the axis of the commutator, the various parts being constructed in detail as more particularly described.

No. 17953.—25th May, 1904.—ELECTRIC AND TRAIN LIGHTING SYNDICATE, LIMITED, of 112, St. James Street, Montreal, Quebec, Canada (assignees of Isidor Deutsch, of 66, University Street, Montreal aforesaid, Electrical Engineer). Means for controlling the voltage from an electric generator.

Extract from Specification.—Our invention relates to improvements in means for controlling the voltage from an electric generator, particularly those generators subject to sudden variations in speed, and the object of the invention is to cheapen the construction of such devices, and to provide a noiseless mechanism which shall be positive as a regulator in its operations at a minimum expenditure of electric energy, and it consists essentially of a dynamo, a rheostat in the shunt-field circuit of said dynamo, a cylinder and piston operating therein, having a rod preferably provided with annular grooves, a connecting-arm from said piston-rod to the contacts having connection with said rheostat, a solenoid, and suitable admission and exhaust valves and arms for the cylinder, the various parts being constructed and arranged in detail as particularly described.

No. 17964.—25th May, 1904.—ALFRED DIVINE, of Devon Street, New Plymouth, New Zealand, Advertising Agent. Advertising exhibitor and newspaper-file.

Claim.—As an advertising exhibitor and newspaper-file, comprising two brass tubes with finials, made of any other metal, &c., fixed to the wall or woodwork erect, having brass pliable wires, &c., secured to them for exhibiting printing and other papers, as described thereon.

No. 18084.—22nd June, 1904.—JABEZ ADAMS, of “Glenmire,” Thomson Street, Hamilton, Dundas, Victoria, Australia, Constable. Improved nut-wrench.

Extract from Specification.—My invention includes a nut ring or band. This at the top and bottom has collars. Between the said collars are ratchet-teeth. Through the nut-ring is a concentric hole. The internal conformation of this hole is of the same external conformation, whether square or hexagon, as the nut, and it is of such a size that the ring fits comfortably over the said nut. In thickness each front end C of the handle where it engages with the nut-ring is less than the distance between the collars A. The said front end is of circular conformation, so that it agrees with the circumference of the ratchet-toothed portion of the nut ring or band. The body or middle F of the handle is provided with lightening spaces O. Each nut-ring is retained against each front end C of the handle by a metallic strap D. This strap, which is U-shaped in plan, fits between the collars A of the nut-rings, and its legs E are secured or united to the body or middle F of the handle by rivets G or other means. Between one of the legs E of the strap D and the front end C of the handle and in the said handle is a rectangular-shaped recess. Into this recess is placed a plate ratchet Q. The front end of the ratchet Q by the spring H is forced against the teeth B and the rear end presses against the step formed in the handle by the back end of the said recess. If a double-ended spanner is used, as shown in the illustrations, instead of there being a strap at each end of the said spanner there may be one continuous strap, the meeting ends of which can lap or butt and be secured to the handle as desired.

No. 18101.—30th June, 1904.—WILLIAM GEORGE GRAVE, of Thames Street, Oamaru, Otago, New Zealand, Sailmaker. Improved means for securing covers upon animals.

Claims.—(1.) Improved means for securing covers upon animals, consisting of the two girths connected, arranged, and operating, substantially as specified and illustrated. (2.) For the purpose indicated, a girth having a buckle at one end designed to be secured to a strap upon one side of the cover extending beneath the animal and threaded through the cover upon the opposite side; then continued diagonally across beneath the animal, and having a buckle connected to a second strap upon the same side as the first; a second girth connected at one end of the first girth at the point of attachment of the first buckle carried diagonally across beneath the animal and threaded through the cover, and then carried across the animal and secured to the other end of the first girth on the point of connection with the second buckle, substantially as specified, and illustrated in the drawing.

No. 18102.—30th June, 1904.—ALFRED ERNEST BRADLEY and HAROLD GLADSTONE BRADLEY, both of 299, Colombo Street, Christchurch, Canterbury, New Zealand, Plumbers. Improvements in and relating to apparatus for pumping water.

Claims.—(1.) Apparatus for the purpose indicated, comprising in combination a motor, a pump driven therefrom, and means for conveying water from said pump through a jacket surrounding the cylinder of the motor for the purpose of cooling said cylinder, substantially as specified. (2.) Means for cutting off supply of gas to a motor when a tank has been supplied with water, comprising in combination a pivoted ball float within said tank, a plate electrically connected through a battery with an electro-magnet and a terminal engageable by said plate connected by a wire with a tap upon the gas-supply pipe, a lever operating said tap, a balance-weight thereon, and a hooked end of said lever engaging with a projection from an armature in connection with said electro-magnet, substantially as specified. (3.) For the purpose indicated, the parts arranged, combined, and operating substantially as and for the purposes specified, and as illustrated in the drawing.
