No. 22150.—24th March, 1906.—J. SAMUEL WHITE AND COMPANY, LIMITED, Shipbuilders and Engineers, EDWIN CHARLES CARNT, Engineer, and ANDREW FORSTER, Engineer, all of East Cowes, Isle of Wight, England. Improvements in marine turbines.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

———

Claims.—(1.) A marine turbine of the class characterized by such an arrangement of the blading, and such arrangements for admission and passage of steam thereto and there-through, that the steam supplied to the turbine first acts on portions of the blading in opposite directions so as to balance its own pressure, and afterwards acts on another portion in opposition to the thrust of the propeller, which characteristics admit of a dummy piston being dispensed with. (2.) A marine turbine embodying the characteristics defined in the foregoing claim, and having the whole of the self-balance at one end of the turbine, as exemplified in Figs. 1 and 3 of the drawing. (3.) A marine turbine embodying the characteristics defined in claim 1, and having the self-balance in two parts, one at each end of the turbine, with a steam-inlet at each of the said parts, as exemplified in Fig. 2 of the drawing. (4.) A marine turbine having the characteristics defined in claim 1, and having a portion of the drum at the self-balance part of larger diameter than the remainder of the drum at that part, as exemplified in Fig. 3 of the drawing, and for the purpose set forth.

No. 22171.—7th December, 1906.—EDWARD WILLIAM BARTON-WRIGHT, of 1 Albermarle Street, Piccadilly, London, England, and QUINTON MARINO, of 2 Fitzroy Street, London aforesaid, Engineers. Improvements in the treatment of wood to be used in electro-chemical apparatus.

———

Claims.—(1.) In the treatment of wood for constructing electric batteries or accumulators, submitting the same, in the form of plates, tubes, fibres, or the like, to the influence of ammoniacal-cupreous liquor, and afterwards to a bath of liquid ammonia, from which it is withdrawn, washed in water and immersed in nitric acid, after which it is submitted to the action of sulphurous acid and to a solution composed of alcohol, acetate of ethyl, and caustic potash in various proportions for rendering it porous and permeable by the electric current whilst remaining neutral to the electric chemical reactions, substantially as described. (2.) The improved process for treating wood in the construction of electric batteries and the like, consisting in utilising a bath of pure ammonia solution at the end of the operations or treatment herein claimed so as to render neutral the wood impregnated with the sulphonic liquid, substantially as described. (3.) The improvements in the treatment of wood to be used in electro-chemical apparatus, substantially as described and set forth.

(Specification, 5s. 6d.)

No. 22174.—10th December, 1906.—GIES GEAR COMPANY, of 345 Bellevue Avenue, Detroit, Michigan, United States of America, Manufacturers (assignees of Frank G. Gies, of 345 Bellevue Avenue, aforesaid, Engineer). Improvements in reversing-gear.

———

Claims.—(1.) A reversing-gear adapted for combination with driving and driven shafts axially in line, and consisting of a spur gear and a sprocket, each secured to one of said shafts, a carrier or casing provided with a counter-shaft carrying a spur wheel engaging that of the driving-shaft, and a sprocket, a chain carried by both sprockets, means for arresting the rotation of the casing or carrier, and means for connecting the casing to or releasing it from connection with the driven shaft. (2.) In a reversing-gear, the driving and driven shafts in line, and provided respectively with a gear and sprocket, combined with a casing in two parts detachably connected and supporting a counter-shaft provided with a pinion and sprocket, and a sprocket chain engaging the two sprocket wheels. (3.) The combination with the two shafts, gears, sprockets, segments, and casing, of a single lever and connections, whereby the said lever operates the segments to clamp the casing to the shaft 2 and disconnect it therefrom, and to contract the band about the flange 15 of the casing, through the medium of a lever and wedge. (4.) The combination of the shafts 1 and 2, a casing provided with a counter-shaft, gears 4 and 14, sprocket wheels 5 and 12, a chain 13, a flange on the casing, arms carried by the shaft 2, and means carried by said arms for locking the casing to and releasing it from the shaft 2, together with a brake band for arresting the rotation of the casing.

No. 22178.—10th December, 1906.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of Linotype and Machinery Limited, of 188 and 189 Fleet Street, London, England, the assignees of Jacques Mayer and Christian Augustus Albrecht, of 17-18 Chauseestrasse, Berlin, Germany). Improvements in linotype machines.

———

Claims.—(1.) The combination with a pivoted channelled matrix-guide consisting of two parts 25, 26 adapted to slide endwise over each other, of the specified means by which the act of shifting a series of escapement rods to effect a change of fount in a composing-machine having two or more magazines arranged one above the other makes the top of the said pivoted channelled matrix-guide register with the mouths of the respective magazine. (2.) In the means claimed in the preceding claim, the combination of pivoted channelled matrix-guides 25, 26, reciprocating-plate 22, shift lever 8, and connections between the latter and the said plate. (3.) The combination of two continuous belts, or one continuous belt and one annular surface, adapted to receive and grip between them the matrices of a fount rejected by a preliminary distributor, and by being parallel for only a portion of their course to carry the said matrices so far and then send them on their way to their distributor for character. (4.) The improved preliminary distributor characterized by two continuous belts, or one continuous belt and one annular surface, adapted to carry the matrices of a fount rejected by a preliminary distributor away from the latter, to lift them, and to then drop them towards their distributor for character. (5.) The described combination of shoot, rocking-plate forming part of the top thereof, spring holding it in normal position, bell-crank lever rocking with the said plate, and a bell-crank lever controlling the driving-clutch of the mechanism that drives the distributor-screws, held away from the said clutch by the first-mentioned lever so long as the rocking-plate is in normal position, and pulled towards the axis of the said clutch by a spring as soon as the rocking-plate is rocked out of normal position by a matrix jammed in the shoot.

Claims.—(1.) In machines for making paper bags, having a rising and falling table carrying a platform, the employment of a roller in said rising table and a sensitive finger for drawing each sheet of paper to a gauge on said rising table, substantially as set forth. (2.) In machines for making paper bags, a spring-controlled folding and pressing roller, operated to rub one edge of the paper against a pasting-roller, and then passing it on to the other edge of the paper and pressing it thereon, substantially as set forth. (3.) In machines for making paper bags, a shooting paste-box carrying folding appliances for applying paste to the top portion of the bottom of the bag and folding the top edge of the paper downwards, substantially as set forth. (4.) In machines for making paper bags, a folding-appliance for folding the bottom portion of the bottom of the bag, said folding-appliance carrying spring-controlled flaps for pasting the tabs after having received the paste from the shooting paste-boxes, substantially as and in the manner set forth. (5.) In machines for making paper bags, the employment of four sectors for compressing the tubular bag and drawing it off the mould, in conjunction with spring or spring-controlled tucking-appliances, a presser and a lifting roller, substantially as and for the purpose set forth. (6.) The improvements in machines for making paper bags, substantially as set forth.
