No. 14155. — 24th October, 1901. — EDWARD AUGUSTUS BISHOP, of York Street, Sydney, New South Wales, Pianoforte-manufacturer. A sheet-music cabinet attachment to pianofortes.*

Claim.—In pianos, organs, or other similar musical instruments, the lower door in combination with a cabinet to receive sheet music, the whole being so disposed and arranged that the cabinet may be tilted forward on a pivot or hinge so that the sheet music within the cabinet may be readily accessible to the performer on the instrument, as set forth.

No. 14430.—14th January, 1902.—WILLIAM THOMAS LOCKE TRAVERS, of Wellington, New Zealand, Barrister and Solicitor (nominee of John Sedgwick Peck, of 604, South Dallas Street, Pittsburg, Pennsylvania, United States of America, Engineer). Improvements in systems of electrical distribution.

Extract from Specification.—This invention relates to systems of electrical distribution in which translating-devices are supplied with energy from three-wire direct-current circuits. One object of the invention is to provide an arrangement for transforming three-phase alternating currents into direct currents for distribution on the three-wire system by the aid of three two-circuit transformers and a rotary transformer. The invention further includes means for supplying direct currents on the three-wire system from a single dynamo machine with the aid of three auto-transformers; the said dynamo machine may also be arranged to supply three-phase alternating currents in addition if desired. It has heretofore been suggested to utilise an ordinary three-phase transformer with the secondary winding connected in star fashion to three collector rings on the shaft of a rotary transformer, the balancing or neutral conductor of the three-wire direct-current circuit being connected to the middle or neutral point of the secondary winding of the transformer. In such an arrangement, however, the current flowing through the secondary winding from the balancing conductor of the three-wire circuit will serve to magnetise the transformer core to substantially saturation-point, and thus increase the various losses in the transformer. According to the present invention, these objectionable results are avoided by connecting the neutral conductor of the three-wire circuit to the windings or secondary windings of the transformers in such a manner that the currents flowing to the secondary windings will, by reason of such connections, be in opposition in the two halves of the said winding, and thus neutralise each other so far as magnetic effects are concerned.
Claim.—Systems of electrical distribution arranged and operating substantially as described with reference to the drawings, for the purpose specified.

No. 14435.—15th January, 1902.—JOHN BLACK, Draper, JOHN ALFRED STRINGER, Builder, and ALFRED WILLIAM CLAYDEN, Manager John Scott’s Estate, all of Nelson, New Zealand. Improvements in or relating to the construction of hot-houses and the like.

Extract from Specification.—In carrying out our invention, we construct the sides of the glass house with studs that extend throughout the whole height of the house. These studs are cut away for a distance up from the bottom equal to the height it is proposed to carry the rusticating, so that when such rusticating is fixed upon the studs its surface shall only project slightly beyond the face of the top part of the studs. The top board of the rusticating is rabbeted on its top edge with a deep rabbet. The sides of the studs above the rusticating are also rabbeted. The panes of glass are then placed so that their bottom edges shall rest in the rabbet on the rusticating, and their sides in the rabbets upon the studs, after which battens are laid over the edges of the glass and secured against the faces of the studs, so as to secure the glass.
Claim.—The improved manner of constructing the sides of hothouses and the like, as described and explained, and as illustrated in the sheet of drawings, and for the purposes set forth.

No. 14460.—22nd January, 1902.—JOHN MACPHERSON, of Wellington, New Zealand, Consulting Engineer, and LOUIS PHILLIPS, of Greymouth, New Zealand, Engineer. Improved appliances for delivering tailings from gold-saving dredges, and for other analogous purposes.

Claims.—(1.) In means for delivering tailings and the like, an oscillating lever-arm mounted beneath a hopper or chute, and provided with a receptacle on the end thereof, such lever-arm being connected to means whereby it may be caused to travel rapidly through its arc of movement, and to remain stationary at each limit thereof, as specified. (2.) In means for delivering tailings and the like, an oscillating lever-arm, the top end of which is provided with a receptacle adapted to hold the material to be delivered, and the bottom end of which is connected to a hanging beam that is caused to oscillate by means of a crank-pin engaging with a slot therein, regularly alternately fast and slow motion being communicated to such beam by any suitable appliances, as set forth. (3.) In means for delivering tailings and the like, an oscillating lever-arm and an oscillating beam coupled together so as to work synchronously, a crank-pin engaging with a slot in the beam, elliptical gearing operating the crank-pin so that its rotary motion shall be regularly alternately fast and slow, and gearing for conveying motion to the elliptical wheels, as specified. (4.) In means for delivering tailings and the like, a chute or hopper mounted above a receptacle upon the end of an oscillating lever-arm, such chute or hopper being provided with a sliding door in the bottom thereof, in combination with means whereby such sliding door may be caused to open and close as the receptacle upon the lever-arm comes beneath it and moves away therefrom, as specified. (5.) The general arrangement, construction, and combination of parts in our improved appliances for delivering tailings from gold-saving dredges, and for other analogous purposes, as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 14462.—22nd January, 1902.—WILLIAM CURRIE, of Hillsborough, near Christchurch, New Zealand, Platelayer. Improved ballast-spreading machine.

Claims.—(1.) The improved ballast-spreading machine consisting of the parts combined, arranged, and operating substantially as and for the purposes described and illustrated. (2.) The ballast-spreading machine comprising the curved spreader sides connected to a point which acts as a share, said sides being mounted upon T-headed rails, substantially as and for the purposes specified and illustrated. (3.) In a ballast-spreading machine, the combination of the curves, spreader sides converging to a share to which they are attached, T-headed rails to which the sides are attached, upwardly projecting bars connected by a pin which is engaged by a coupling-hook of the ballast-truck, and stay-rods from such bars to the sides of the machine, substantially as and for the purposes specified and illustrated.

No. 14464. — 22nd January, 1902. — GERALD JOSEPH PEROTTI, of Greymouth, New Zealand, Timber Merchant. Improved amalgamating apparatus for gold-saving purposes.

Claims.—(1.) The improved amalgamating apparatus consisting of the parts arranged, combined, and operating substantially as and for the purposes specified and illustrated. (2.) In amalgamating apparatus, the combination with a revolvable barrel of an axle provided with concave paddles adapted to agitate and to raise material contained with the barrel, substantially as and for the purposes specified and illustrated. (3.) In amalgamating apparatus, the employment of ribs fixed upon the inner periphery of the barrel which contains the material to be treated, substantially as and for the purposes specified and illustrated. (4.) In amalgamating apparatus, a barrel provided with a discharge-opening such as specified and illustrated.

(2.) In combination with a wire-strainer as covered by the preceding claim, the use of clips such as O, O, for splicing the ends of the wire operated upon, substantially as described and illustrated in Figs. 5 and 6 of the drawing.
