automatically brought into action in turn in order to generate the gas as each one becomes exhausted, and also to means whereby the generating operation may be stopped when a gasometer comprised in the apparatus becomes fully charged with gas, and restarted when the gas is about exhausted therefrom. Other improvements in the details of construction are embodied, and will be more particularly indicated in the claims.

No. 20843.—14th March, 1906.—ALBERT ERNEST WOODHOUSE, of Amuri, Wellington Street, Kew, Victoria, Australia, Electrical Engineer. Improved conduit for electric conductors.*

Extract from Specification.—This invention of improved conduit for electric conductors has been designed for wiring houses and buildings and for protecting electric conductors. The conduit is preferably made up in four parts, all of which are usually constructed of thin metal—viz. (a) the troughing, which is of a tapering section, wider at the top open part than at the bottom; (b) clip pieces which are secured to the wall or ceiling and engage or grip the outer sides of the troughing in order to hold it in position; (c) removable covers for the troughing and which have inwardly splayed marginal rims for being sprung over the top parts of the sides of the troughing; and (d) joint caps which are made of the same section as the covers and designed to be sprung over the top of same at the joints thereof in order to form the cover-strips: and by thus assembling the several parts forming the conduit an electric bond is secured. By providing the conduit with removable covers the wires can be readily laid and inspected. Further, when so desired the troughing may have insulated material run or moulded into it, having one or more grooves therein in order to receive bare conductors, and the end parts of the troughing may either be butt- or lap-jointed. Furthermore, the said clips and joint-caps may be constructed of a suitable section to be applied to the troughing and covers of conduits of a sectional form—other than those referred to herein.

No. 20936.—2nd April, 1905.—HILARY QUERTIER, of Oraki House, Rattray Street, Dunedin, Otago, New Zealand, Engineer. Improvements in rail-cleaners for tramways and the like.*

Extract from Specification.—This invention provides means for use upon motors, tram-cars, and the like for removing the dust and dirt from tramway rails and from the grooves therein, and collecting the dirt and dust so removed in order that it may be readily taken away. According hereto a rail-plough, comprised of scrapers for removing the dirt from the rail and its groove, and hoppers to which the scrapers are connected to a rod by a spring attachment, the said rod being provided with a lever for adjusting the height of the ploughs from the rail. The plough is double-acting, and has two scrapers and a double hopper, one scraper coming into operation when the vehicle travels in one direction, and the other scraper coming into use when the travel is in the opposite direction. The ploughs are pivoted upon a central axle revolved by a sprocket and tooth wheels and chain from an axle of the vehicle. The ploughs yield when an immovable obstacle is met with, and return again into their operative position. Brushes secured upon axles mounted in a frame, or upon arms pivoted upon the central axle, are revolved by chains and sprocket wheels driven by the central axle. A rod connected to the frame or arm has notches adapted to engage a catch for raising or lowering the brushes, and a spring is provided for keeping the notches normally engaged with the catch. A chain carrying buckets passes around a tumbler or a sprocket wheel secured upon the central axle, and around other tumblers or sprocket wheels mounted on a shaft having bearings above a bin. The buckets are double, and convey the dirt from the ploughs to the bin, independently of the direction in which the vehicle is travelling. The bottom of the bin is hinged, or provided with a door operable by a handle when it is desired to remove the dirt therefrom. The wearing part of the plough is readily removable from the hopper for the purposes of renewal when worn. In a modification of my invention I provide two chains of buckets, bins, and ploughs, one set removing the dirt when the vehicle is travelling in one direction, and the other set when the travel is reversed. In this case the buckets and ploughs are single, and the chains of buckets are driven by a sprocket wheel secured to an axle of the vehicle, and by a chain passing around upper tumblers of the bucket-chains. The brushes are arranged and driven as described in my specification No. 20581, “Improvements in rail-cleaners for tramways and the like,” of 16th January, 1906.

No. 21166.—17th May, 1906.—FREDERIC HENRY TREVELLIAN, of National Chambers, Grey Street, Wellington, New Zealand, Cash-register Expert. An improved cash-register.*

Extract from Specification.—This invention relates to the class of apparatus known as cash-registers wherein a sliding till or drawer divided into compartments is used for containing coins and the like. The object of my invention is to provide apparatus wherein a salesman can make out an invoice or docket, and record a duplicate copy thereof upon a continuous strip of paper, which copy cannot be tampered with and is withdrawn into the apparatus beyond the reach of the salesman by the action of opening the till-drawer. The total of each invoice is entered by the salesman upon a separate strip of paper, which is withdrawn into the apparatus simultaneously with the strip containing the copy of the invoice, but to a distance sufficient only to withdraw one row of figures.

No. 21716.—29th August, 1906.—WILLIAM BALDWIN, of 21 Falmouth Chambers, 117 Pitt Street, Sydney, New South Wales, Australia, but presently of Durban, Natal, Merchant. Improved method of fastening and joining roofing or lining manufactured from fibrous material rendered waterproof.

Claims.—(1.) An improved method of forming joints in roofing or lining material by the application of heat, as described. (2.) An improved method of fastening and joining roofing and lining material by nailing the underlap and securing the laps to each other by the application of heat, as described, and illustrated in the drawings. (3.) Fastening roofing material at the joints or elsewhere to the wood lining or battens by means of heat, as described.
