pening at one side into the gear-housing by a gap substantially the full width of the housing-cavity; a countershaft in its housing; a pinion loose on the countershaft in the pinion-housing and stopped at one end against the side of the housing, and a fork-plate secured to the web of the gear-housing and having its fingers intruding into the pinion-housing at the opposite end of the pinion for stopping the latter endwise. (2.) In combination with a shaft-hanger having a shaft journaled therein, a pinion loose on the shaft and stopped independently of the latter against endwise movement in either direction; a clutch member on the pinion and a companion clutch member fast on the shaft, said clutch members having corresponding sloping shoulders for engagement with each other, the shaft being longitudinally movable in its bearings; a lever mounted on the bearing and connected with the shaft for receiving and transmitting such longitudinal movement, and means on the bearing for holding the lever at the position to which it is moved by the longitudinal movement of the shaft. (3.) In combination with a hanger, a shaft journaled therein; a pinion loose on the shaft and stopped independently of the shaft against endwise movement; co-operating clutch members on the pinion and shaft respectively having sloping shoulders for driving engagement with each other, the shaft being movable longitudinally in the bearings, and means for holding it yieldingly at the position to which it is thus moved. (4.) In combination with a hanger, a shaft journaled therein; a pinion loose on the shaft and stopped independently of the shaft against endwise movement; co-operating clutch members on the pinion and shaft respectively having sloping shoulders for driving engagement with each other, the shaft being movable longitudinally in the bearings; a lever fulcrumed on the bearing and engaging the shaft for giving it longitudinal movement, and a spring plate along which the lever moves, said plate having an angular upraise protruding toward the lever, the lever having the side toward the plate formed with an angle for encountering said angular upraise. (5.) In combination with a hanger, a shaft journaled therein; a pinion loose on the shaft and stopped independently of the shaft against endwise movement; co-operating clutch members on the pinion of the shaft, the shaft being movable longitudinally in its bearings and having an annular groove near the end; a lever fulcrumed on the bearing having a finger which takes into the annular groove of the shaft, and having a second finger which projects past the end of the shaft, and a taper-pointed screw set through the last-mentioned finger for bearing against the end of the shaft in the movement of the shaft which brings the clutch members into engagement.

No. 19557.—6th June, 1905.—ALEXANDER STORRIE, of Invercargill, New Zealand, Implement-maker. Improvements in agricultural implements used for the combined purposes of ridging and sowing.

Extract from Specification.—The invention provides improvements consisting (1) in carrying a roller-scraper, coulter-carrying apparatus, and spreader-chain all from one casting fixed upon the frame which carries the concave rollers; (2) an arrangement of the scrapers for the concave rollers whereby jamming with rubbish is impossible; (3) new apparatus for carrying the seeding-coulters whereby their rise when an obstacle is struck is much facilitated, and whereby certain bars of the frame formerly employed are dispensed with; (4) in the employment of disc-coulters revolvably mounted upon the seeding-coulters. According to my invention the frame members upon each side of the machine which carry the brackets in which the axle of the concave rollers is journaled project upwardly at their ends and carry a transverse bar which extends across the machine from one frame member to the other, said bar being behind and above the axle of the rollers. The coulter revolving or stationary carrying apparatus, spreading-chain, and scrapers for clearing the concave rollers are all carried from this bar in a manner which will be fully described.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19560.—7th June, 1905.—HUBERT VINCENT BLAKE, of Oxford Street Works, Accrington, Lancaster, England, Hydraulic Engineer. Improvements in hydraulic rams.

Claims.—(1.) The improved hydraulic ram in which the casings of the pulse and delivery valves are placed one above the other and formed as one piece of metal, substantially as and for the purposes described. (2.) The improved hydraulic ram in which the combined casing of the pulse and delivery valves is so placed in the ram that the bolts which secure the air-vessel to the body of the ram also secure the said casing in position. (3.) A pulse-valve frame formed in two parts, pivoted together on a bolt so that the band-valve carried by them can be adjusted to more or less fill the valve-casing as required, substantially as and for the purposes described.
(Specification, 3s.; drawings, 3s.)

No. 19563.—7th June, 1905.—THE EMPIRE INVENTIONS COMPANY, LIMITED, a company registered in accordance with the laws of the State of New South Wales, Australia, and having their office at Equitable Buildings, No. 350, George Street, Sydney, New South Wales aforesaid (assignees of Charles Launcelot Garland, of No. 154, Phillip Street, Sydney aforesaid, Mining-dredge Proprietor, George Proudfoot, Railway Contractor, and Marion Bowen, Married Woman, both of No. 13, Montague Street, Balmain, near Sydney aforesaid). Improved fire-escape.

Claims.—(1.) In a fire-escape, the combination with a fixed drum or sheave, of upper and lower extensions each carrying hooks and snubs arranged relatively inwardly and outwardly of the depth of the said drum or sheave, substantially as described and explained. (2.) In a fire-escape, the combination with a fixed drum or sheave having upper and lower hooks and snubs, of a hook for a support or seat set-back of the lower hook and snub, substantially as described and explained. (3.) In a fire-escape, the combination with a fixed drum or sheave having upper and lower extensions, of a groove or channel for the cord or rope, and a lever or cam adapted to be pressed into said groove or channel, substantially as described and explained. (4.) In a fire-escape, the combination with a fixed drum or sheave having upper and lower extensions and a seat or support, of lugs for the attachment of the ends of a life-line or wire rope, substantially as described and explained. (5.) In a fire-escape as set forth, constructing the fixed drum or sheave as a receptacle capable of being sealed for water or cooling medium, substantially as described and explained. (6.) In a fire-escape, the combination with a running-piece for engaging with a life-line, of a support of hook shape terminating in a saddle, substantially as described and explained. (7.) The combination or aggregation of mechanical parts all together forming improved fire-escapes, substantially as described and explained, and as illustrated respectively in Figs. 1 to 4, in Fig. 5, and in Figs. 6 and 7 of the drawings.

No. 19604.—14th June, 1905.—FRANCIS WILLIAM PAYNE and ROBERT McLINTOCK, both of Dunedin, New Zealand, Mechanical Engineers. A hot-blast apparatus for aiding combustion in steam-boilers.

Claims.—(1.) In supplying a forced hot blast to furnaces, the combination of a high-pressure steam-jet for inducing a stream of air, said air being previously heated, with means of regulating the proportions of the steam and heated air, and also of regulating the force of said blast as it impinges on the fuel, all substantially as described, and as explained and as illustrated in the drawings. (2.) In combination, apparatus consisting of means of heating air, inducing same so as to cause the said hot air to impinge on the fuel in a boiler-furnace, with the means of regulation of the relative quantities of air to the steam used, and also of the strength and volume of the said hot blast, all substantially as set forth, and shown on the drawings. (3.) In combination, the apparatus as set forth for heating the air to be forced to aid combustion, with the apparatus consisting of a high-pressure steam-jet, pipes and caps for delivering said hot blast in thin sheets to the fuel, and the means of regulating the amount of said hot air with a given amount of steam in said jet, all substantially as set forth, and as shown on the drawing.
