[No. 28

lene-gas generators and holders, all substantially as and for the purposes set forth. (2.) In an acetylene-gas generator and holder of the class described, a series of carbide-chambers, each having two receptacles with a water-pipe in the outer receptacle, having its upper end nearly at the top thereof and the other end opening at the base thereof, and two opposite holes in the partition between the receptacles a little lower than the upper end of the water-pipe, substantially as described. (3.) In an acetylene-gas generator and holder of the class described, a generator comprising an outer chamber in which a bell slides, said outer chamber containing a series of carbide-chambers such as described superimposed in a receptacle, and means for supplying water to said carbide chambers whereby the carbide is exhausted from the topmost to the lowermost chamber in succession, substantially as described. (4.) In an acetylene-gas generator and holder of the class described, a gas-holder provided with a water outlet-pipe near the top thereof, and extending to the generator, said outlet-pipe being opened and closed by a valve actuated by mechanism between it and the bell of the gas-holder, whereby the carbide-chambers are automatically supplied with the exact quantity of water to suit the number of lights, substantially as described.

No. 19118.—22nd February, 1905.—ALWIN HUGO EUSEBIUS FISCHER, of North Adelaide, South Australia, Plumber. Improved heating-plates for jacketed water-heaters and for the flues thereof.

Extract from Specification.—I construct the jacket of my water-heaters of an outside cylinder A and an inner cylinder B, but instead of forming the inner cylinder in the usual manner by rounding up a plain sheet of metal I form the same by repeatedly turning the metal alternately inwards and outwards as shown in the drawings, and thereby forming any desired number of thin water-spaces C, which projecting into the heating-chamber of the furnace of a water-heater, or into the flue which conducts the heated air from the furnace, very materially increase the heating-power and effectiveness of the water-heater.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19119.—22nd February, 1905. — ALFRED SPAULDING PATTERSON, of 570–576, Bourke Street, Melbourne, Victoria, Australia, Manager of the Massey-Harris Company, Limited (nominee of Lyman Melvin Jones, Robert Henry Verity, and Charles McLeod, all of No. 915, King Street West, Toronto, Ontario, Canada, Manufacturers). Improvements in mowers.

Extract from Specification.—The object of this invention is to improve the general construction of the mower, and it consists essentially (1) of improvements in the means of carrying the cutter-bar, (2) of improvements in the guide or wearing plates for the heel of the knife, (3) of improvements in the guard or shield for balance crank, (4) of improvements in the adjustment of the pitman, and (5) of certain improvements in the swathboard of the divider by which its liability to injury by contact with obstructions is greatly lessened, and a better track is made for the inner shoe on its next round, all substantially as more specifically described and then definitely claimed.

No. 19121. — 10th August, 1904. — RICHARD KNOWLES PARKERSON, of Ealing, Canterbury, New Zealand, Sheep-farmer. An improved water-motor.

Extract from Specification.—This invention provides an improved water-motor for employment more particularly in rivers and watercourses having a rapid current. The motor comprises a series of vanes or floats carried upon endless chains working over sprocket wheels or drums. Two of the sprocket-wheels are fixed upon each of two horizontal shafts arranged at a convenient distance apart, and the chains connect the opposing sprockets upon the respective shafts. The vanes are connected to the chains in such manner that they lie approximately horizontal when out of the water, and upon entering the water turn over with their faces in a plain at right angles to the current. The shafts are journalled in bearings carried upon pontoons floating upon the water, or upon piers of masonry or the like. There may be a plurality of sets of apparatus as above outlined arranged side by side and connected to form one motor.

No. 19126. — 23rd February, 1905. — GEORGE SKAATS MAYHEW, of 2, Basinghall Avenue, in the City and County of London, England, Engineer. Improvements in or relating to machinery for sawing and planing.

Claims.—(1.) In a machine for sawing thin slices from deals or planks and planing said slices on both sides, an adjustable guide provided with evening and smoothing planes and friction and feeding rollers respectively adapted to even and smooth the slicing-face of the deal and to move it forwards against a saw arranged at the end of said guide, and a spreader adapted to separate the slice from the deal as it is cut by said saw and to lead it to an adjustable guide provided with friction and feeding rollers adapted to move the slice forward through its guide, and smoothing-planes adapted to smooth the back face of said slice, substantially as described. (2.) In a machine for sawing thin slices from deals or planks and planing said slices on both sides, a bed-plate provided with a slot adapted to form a guide for the deal in which one side is formed in sections provided with friction-rollers and evening and smoothing planes adapted to even and smooth the slicing-face of the deal, while the other side of said slot is formed in one piece adapted to be adjusted according to the thickness of the deal and provided with feeding-rollers adapted to feed the deal forwards against a saw arranged at the end of the said guide slot, and a spreader adapted to separate the slice from the deal as it is cut by said saw and to lead it to an adjustable guide provided on the one side with friction-rollers and smoothing-planes adapted to smooth off the saw-marks from the back face of the slice, and on the other side with feeding-rollers adapted to feed the slice forward through said guide as it comes off the deal, substantially as described. (3.) In a sawing and planing machine of the character described, a cutter-head adapted to be automatically operated by a full-sized deal to move across the guide slot to groove the head of the deal, and means for automatically returning the said cutter-head to its position beneath the table after said deal-head has been grooved, substantially as and for the purpose described. (4.) In a sawing and planing machine of the character described, an adjustable spreader adapted to separate the slice from the deal as it is cut by the saw, substantially as and for the purpose described. (5.) In a sawing and planing machine of the character described, an adjustable frame adapted to form a bearing for the back face of the deal beyond the end of the guide, and means for locking said frame in position, substantially as described and shown in Fig. 9 of the drawings. (6.) In a sawing and planing machine, the construction and arrangement of parts substantially as described and shown in the drawings.

No. 19132.—24th February, 1905.—FRANK DUNNINGTON HOPKINS, of San Francisco, California, United States of America, Inventor. Improvements in gun-sights.

Claims.—(1.) A gun-sight having a spot surrounded by a visually contrasting field. (2.) A gun-sight having a spot surrounded by a field of contrasting colour. (3.) A unsight having a black spot surrounded by a white field.
(Specification, 2s. 3d.; drawing, 1s.)

No. 19134.—25th February, 1905. — EDWIN D. BILHAM, of Waimata, Gisborne, Auckland, New Zealand, Station-manager. Improvements in fencing-standards.

Extract from Specification.—The standard is made of angle iron or steel notched to receive the wires of the fence and pointed at one end. A thrust-plate of angle iron or steel is provided with a hole through which the standard is passed after the plate has been sunk slightly below the surface of the ground. Where the tendency of the strain of the wires is to force the standard into the ground I provide holes near the pointed end of the standard and other holes in the thrust-plate through which a piece of wire is threaded. The standard is thus united to the plate, which offers a large surface to the ground.
[NOTE.—The above extract from the specification is inserted in place of the claims.]
