Claims.—In the manufacture of crackers and the like, means for feeding the material in a continuous manner, endless baking-bands continuously moving at right angles to the direction of the feed for baking the same in sections, means for indenting the material and locking the filaments thereof together at points to secure compactness with lightness of structure, and means for discharging the baked product upon a conveyor, substantially as described and shown. (2.) In the manufacture of crackers and the like, a set of baking-irons comprising opposite plates having similar face distributions of projections separated by deep intervals, such projections being oppositely placed with reference to each other, and in contact, or approximate contact, when the irons of the set are placed together, whereby the material between the irons will be fastened or locked together at the ends of the projections, while in the intervals between the projections its fibrous or light structure will be preserved inviolate, but in compact form, substantially as described and shown. (3.) In the manufacture of crackers and the like, a continuous-baking machine, comprising an endless chain of baking-links upon which the material is received, an endless chain of baking-links adapted to cover in the material upon the links of the first chain, means of engagement whereby the links of the two baking-chains are run in exact relation to each other, and means for heating the baking-chains, substantially as described and shown. (4.) In the manufacture of crackers and the like, a baking-machine comprising an outer endless chain of links, an inner endless chain of links, means of engagement between the outer chain and the inner chain, baking-irons connected to said links, and wired for electric heating in connection with brushes of said links, conductor bars in contact with which the brushes of the links move, and means for automatically cutting off the electric action where it is unnecessary, substantially as described and shown. (5.) In the manufacture of crackers and the like, an oven having a feed opening, and within such oven an endless chain of baking-links upon which the material is received, and endless chain of baking-links adapted to cover in the material upon the links of the first chain, means of engagement whereby the links of the two chains are run in exact relation to each other, and means whereby the material is fed to the baking-chains in a continuous manner, substantially as described and shown. (6.) A set of baking-irons having means adapted to form a cracker of filaments of material extending in a more or less undulating manner in one direction and composing superficial ribs, and having in the depressions between such ribs series of indentations, whereby the filaments are fastened or locked together at points to secure a compact form without destroying the lightness of the structure between such indentations, substantially as described and shown. (7.) In the manufacture of crackers and the like, a continuous baking-machine involving an endless chain of linked stoves having means for heating and means whereby the food-material is continuously fed to and delivered from such machine, substantially as described and shown. (8.) In the manufacture of crackers and the like, the combination with an inner endless chain of stove-links, of an outer endless chain of stove-links engaging said inner chain, and extending beyond the same to form a reception-loop for the feed and discharge, substantially as described and shown. (9.) In the manufacture of crackers and the like, the combination of an oven having an opening for the feed, and side-by-side trackways, of a long outer endless chain of stove-links, and a shorter inner endless chain of stove-links having the same pitch line, sprocket wheels for such chains, and means of engagement whereby the links of the chains will be held in exact relation to each other in their movement, substantially as described and shown. (10.) In the manufacture of crackers and the like, the combination with an oven, its trackways and contact bars, of the endless chain of stove-links, the link-conductors, the stoves or baking-irons connected to such links, the wiring of such stoves, and the spring brushes attached to the links and adapted to engage the contact bars, substantially as described and shown. (11.) A cracker consisting of filaments of material extending in a more or less undulating manner in one direction and composing superficial ribs extending in the direction of the filaments, and having in the depressions between such ribs series of indentations, whereby the filaments are fastened or locked together to secure a compact form without destroying the lightness of the structure between such indentations, substantially as described and shown.

No. 17153.—28th October, 1903.—JAMES PALMER CAMPBELL, of Wellington, New Zealand, Solicitor (nominee of the British Westinghouse Electric and Manufacturing Company, Limited, of Westinghouse Building, Norfolk Street, Strand, London, England, Manufacturers). Improvements in fluid-pressure turbines.

———

Claims.—(1.) A fluid-pressure turbine having fixed fluid-guiding passages formed in a ring or rings secured to the casing, said ring or rings being provided with annular flanges which are interleaved with corresponding flanges on the rotary portion of the turbine which carries the moving blades, substantially as and for the purpose described. (2.) A fluid-pressure turbine having fluid-guiding means, constructed substantially as described with reference to Figs. 2 and 3 or to Figs. 4 and 5 or to Figs. 8 to 10 of the drawings. (Specification, 7s.; drawings, 2s.)

No. 17154.—28th October, 1903.—JOHN EDWARD COOPER, of Phoenix Villa, 9, Chatsworth Road, Stratford, London, England, Engineer. Improvements in connection with anti-friction mechanism as applied to railway and other vehicles.

———

Claims.—(1.) The construction of parts in which anti-friction mechanism of the kind described is employed in combination with horn plates and springs with the axle guide-boxes, adapted to be adjustable with the motion of said springs, whereby such anti-friction mechanism is applied to the axle-shafts of railway-carriages and other vehicles in combination with the springs on which the said carriage or vehicle is mounted, the several parts being arranged and operating together substantially as described with reference to Figs. 1 to 9 inclusive of the drawings. (2.) Anti-friction mechanism for use in connection with the axle-shafts of railway-carriages or the like vehicles, in the construction of which a journal-box for the lower or main shaft is connected to a transom plate by bolts, the transom plate being in turn bolted against the bearing-spring buckle by straps passing horse-shoe fashion over the upper or journal-box of the anti-friction shaft, so that by wooden packing-pieces inserted between lugs on the lower or main axle journal-box and the transom plate provision is made for a rigid connection between the journal, journal-box, and collar of the main shaft or axle and the journal, journal-box, and rolling discs of the anti-friction axle and the bearing-spring buckle which comes between, all arranged, combined, and operating together substantially as and for the purpose described, and illustrated in Figs. 10 and 11 of the drawings. (3.) The special arrangement of bearings in the journal-box of the main axle in which sectional bearings of less extent than a semicircle are fitted in seats in the journal-box of like form, so that, whilst the journal is held rigidly in position in respect of any upward movement or change of position, it is in free rolling contact with bearings which can themselves be removed or inserted without disturbing either shaft or journal-box, substantially as described, and illustrated in Figs. 12 and 13 of the drawings.
