(5.) In railway-couplings as set forth, the combination with draw-hook such as 5 having pivoted cradle such as 7, 8, and a shackle such as 10, of a supporting-lever such as 18 and a cross spindle such as 13, of a stop-bar such as 19, a depending spring lever such as 21, angle-rests such as 20, and tail such as 22, for the purposes set forth, substantially as described and explained and as illustrated in the drawings. (6.) The combination and arrangement together of the mechanical parts or integers for the respective purposes set forth, constituting an improved coupling for railway vehicles, substantially as described and explained and as illustrated in the drawings.

Improvements in the manufacture of mantles for gas-lighting.

Claims.—(1.) In the manufacture of incandescent mantles for gas-lighting, precipitating the salt or salts with which the fibrous material is impregnated by means of an organic base or a mixture of organic bases, substantially as and for the purposes set forth. (2.) An incandescent mantle or material for the manufacture of incandescent mantles, manufactured as described.

No. 23782.—4th December, 1907.—HERBERT MANSELL HARDY, of Miller Street, Unley, South Australia, Accountant. An improved method of, and means for, securing sash-cords, and constructional details connected therewith.

Claims.—(1.) An improved method of, and means for, securing sash-cords, consisting of attaching one end of the cord to the window-frame by means of a sliding clip which is accommodated in a suitable slide-carrier in a recess in the frame, said carrier being retained by a sliding cover or other form of locking-device. (2.) In an improved method of, and means for, securing sash-cords, a vertical slide-carrier provided with grooved edges for the accommodation of a sliding clip, said carrier preferably extending horizontally along the top of the sash at right angles to its body portion, and being provided with grooved edges for the accommodation of a sliding cover or locking-plate. (3.) In an improved method of, and means for, securing sash-cords, a sliding clip designed to be accommodated within grooved edges of a slide-carrier as above claimed, and preferably terminating in a portion which is bent at right angles to the body part, so as to be retained in position by a sliding cover or other form of locking-device, said sliding clip being provided with notched edges or projections for gripping the sash-cord. (4.) In an improved method of, and means for, securing sash-cords, a sliding cover which works within suitable horizontal grooves, preferably formed in a horizontal extension of a slide-carrier. (5.) In an improved method of, and means for, securing sash-cords, the combination of a slide-carrier, a sliding clip having notched projections thereon, and a sliding cover for locking the sliding clip in place, substantially as described.

No. 23784.—4th December, 1907.—WILLIAM JOHN CROSSLEY, of Crossley Brothers, Limited, Openshaw, Manchester, Lancaster, England, and THOMAS RIGBY, of The Square, Fairfield, Manchester aforesaid, Engineers. Improvements in and connected with the manufacture of producer-gas.

Extract from Specification.—This invention relates to improvements in and connected with the manufacture of producer-gas, and has for its object the manufacture of producer-gas free from tar, from fuels containing tarry matter, such as bituminous coal, lignite, peat, wood, &c. It is mainly intended for the gasification of bituminous coals, most of which cake hard together during the period the volatile matter is being expelled from them. As a consequence, when used in an ordinary gas-producer these caking coals are very difficult to work, as the caked fuel causes scaffolding and the formation of holes and cavities in the fuel-bed. According to this invention the fuel is spread as described in a layer on a grate or other suitable support, and the fuel is in the first place partially burned and subjected to heat, in such a manner that the volatile matter is expelled, and the tarry matters contained therein consumed, the resulting heat causing the volatile matter to be expelled from the fresh fuel as it is fed in. The air supplied for the combustion of the volatile matter given off from the fuel is termed the primary air-supply. The resultant from this first process consists mainly of carbon and ash, and when the fuel so treated is bituminous coal, the product is a coke free from tar. This resultant, called coke, is according to our invention passed into a gas-producer arranged to receive it. The products of combustion of the volatile matter and primary air will usually be passed, either alone or in conjunction with an additional supply of air, through the hot fuel in the gas-producer. (This additional supply of air is referred to as the secondary air-supply.) In the result the gas produced is free from tar, and most of the heat of the volatile matter is recovered and utilised.

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