No. 29087.—3rd March, 1910.†—LOUIS LUMIÈRE, of 262 Cours Gambetta, Lyons, France, Manufacturer. Improvements in acoustical instruments.

Claim.—A sound-box for acoustical instruments comprising a movable wall and a stationary wall, in which the inner face of the movable wall bears such a form in relation to the inner face of the stationary wall that the surfaces of successive sections taken concentrically with the delivery-orifice of the sound-box between the inner faces of the two walls are substantially equal, so that the instantaneous pressure of the air at all points of the surface of the movable wall is substantially uniform.

(Specification, 2s. 6d.)

No. 29091.—2nd February, 1911.—CHARLES HONOUR, of 1524 Sixth Avenue, New Westminster, British Columbia, Canada, Engineer. Can-containing and pouring vessels.

Extract from Specification.—This invention relates to a containing-vessel within which a can of condensed milk or cream or other liquid sealed in a can may be placed for use on the table, the containing-vessel being provided with sealing-valves by which the pouring and venting apertures in the can are sealed when not in use, and with a handle and spout for convenience in pouring.

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

(Specification, 5s. 3d.)

No. 29164.—23rd February, 1911.—FRANCIS HAROLD DOWDEN, of Nireaha, Wellington, New Zealand, General Store Manager. An improved composition of matter and container for closing punctures in pneumatic tires.

Claims.—(2.) For the purpose indicated, a composition of matter consisting of matai-juice, flour, and water, substantially as set forth. . . . (4.) For the purpose indicated, the collapsible container having its neck screwed internally to fit the nipple of a pneumatic tire, and a stopper adapted to fit the said neck, substantially as set forth.

(Specification, 1s. 6d.)

No. 29182.—25th February, 1911.—CECIL GEORGE MCKELLAR, Assoc. Mech. Eng., of Christchurch, New Zealand, Civil Engineer. Improvements in and relating to the rear-wheel fittings of cycle-frames.

Extract from Specification.—A pair of plates which are adapted to be secured to the rearward extremities of the tubing forming the back forks of the cycle, such plates being each provided with the usual slot to receive the axle of the wheel and allow of sufficient movement for chain-adjustment purposes, while upon the inner surface of such plates, at a point above the slot, is formed an inwardly projecting ridge which is adapted to rest upon the outer end of the bearing-cone or upon a fitting mounted upon such cone. In order to provide for their attachment to the forks, the forward ends of such plates are formed into shanks adapted to fit within the tubing, special means being employed to secure such shanks in place during the brazing of the joints.

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

(Specification, 5s. 9d.)

No. 29185.—27th February, 1911.—JOSEPH FREDERICK WATERHOUSE LYONS, of 31 Glasgow Street, South Dunedin, New Zealand. Improvements in hat-pins.

Claim.—For the purpose indicated, a hat-pin pointed at both ends and having a circumferential groove near each point, and a removable spring-protector upon each end of the pin and engaging the groove thereof, as set forth.

(Specification, 1s. 6d.)

No. 29190.—1st March, 1911.—ENOCHE STEVES MILLER, of 117 Harvey Street, New Westminster, British Columbia, Canada, Accountant. Street-car fenders.

Claims.—(1.) In a car-fender, a net-carrying frame the vertical side members of which are pivotally mounted on the front end of the car, and means for imparting a rotational movement to such vertical side members by connections from the adjacent car-truck frame on a transverse line through the axis of the pivot on which the car-truck moves on taking a curve. (2.) In a car-fender, a net-supporting frame so connected to the front end of the car that the front end of the fender may be laterally swung to one side or the other by connection to the adjacent truck on which the car is carried, means for supporting the fender with its front rail clear of the track in a manner that it will yield backward and downward to the track-level on engagement with an obstacle, and means for lowering said front rail to the track-level by the application of the foot when required.

[NOTE.—Here follows one other claim.]

(Specification, 7s. 3d.)

No. 29192.—7th March, 1910.†—SIDNEY ADOLPH HORSTMANN, of 10 Norfolk Crescent, Bath, England, Engineer. Spring wheel for road-vehicles.

Extract from Specification.—According to my invention, I employ spokes which are incompressible or nearly so in the direction of their length, but are capable of deflection, and act as springs only in a direction at right angles to the plane of the wheel. The inner ends of these spring spokes are attached rigidly to the hub—either in two flanges on the hub, or to a single flange, or in a single row (in which case they must alternately be bent out to one side and the other of the plane of the wheel). The outer extremities of the spokes are attached by short jointed or flexible connecting-means (making an angle to the spoke) to the rim in such a manner that pressure upon the rim causes the spokes to be deflected in a direction at right angles to the plane of the wheel. By this means I am able to obtain long springs of great strength, which are only subjected to a very small proportional deflection, so that the elasticity of the springs is not easily impaired.

No. 29193.—1st March, 1911.—EDWARD CASPAR, of Invercargill, New Zealand, Engine-driver. An improved lime-kiln.

Extract from Specification.—The invention consists, broadly, in providing the bottom portion of the wall of the kiln with a number of separate passages opening out through the wall and extending down to the bottom of the kiln. The openings into these passages are covered by gratings, and are situated below the fire-level of the kiln. The kiln is charged with the limestone in such a manner that the large stones are arranged down its centre, while the medium-sized material is arranged concentrically around them, and then the fine material around the medium and inside the wall of the kiln. To provide for this arrangement of the charge a pair of cylinders of different diameters are arranged one within the other so as to form an annular space between. These cylinders are lowered together into the top of the kiln, and the larger cylinder is made of such a size as to leave a clear annular space between it and the kiln-wall. Thus three chambers are formed, an inner circular chamber and two concentric chambers around it, to receive respectively the three different grades of material. The upper end of the kiln is covered over, and the cover is provided with chambers built thereon to receive the crushed limestone. These chambers are provided with flue-passages extending up through them, and serving to convey the heat given off from the kiln beneath so that such heat will act on the limestone in the required manner to convert it into the carbonate of lime.

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

(Specification, 6s. 3d.)

No. 29196.—1st March, 1911.—FRITZ DEIMEL, of 8 Luisenufer, Berlin, S. 42, Germany, Manufacturer. An igniter acting through a spark produced by friction.

Extract from Specification.—My igniter comprises a pyrophorous body—i.e., a so-called sparker—and a scraper arranged movable relatively to one another outside a receptacle which contains the combustible, and is normally closed by a hinged cover, and the apparatus for producing sparks is constructed in a very advantageous manner, inasmuch as a part of the same—e.g., the scraper—is attached to one end of a spring which automatically returns the scraper into its normal position, the other end of the spring being attached securely to the receptacle.

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