No. 20857.—14th March, 1906. — HENRY LEDGARD, of Princess Street, Hawera, New Zealand, Blacksmith. A nailless horse-shoe.

Extract from Specification.—The special feature of this invention is the means for preventing the heel portion of the plate from shifting at the heel of the hoof. This is done by providing beaker-shaped pieces (14), (15) integral with the plate, each of these pieces having a portion (16), (17) turned down to lie next the frog (18) of the hoof.

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

No. 20890.—21st March, 1906.—MATTHEW TEASDALE, of Thames, Auckland, New Zealand, Plumber. An improved lantern.

Extract from Specification.—The construction devised consists of two metal bands adapted to loosely encircle the body of the bottle, one at the bottom thereof and one at the top, and which are rigidly connected together by means of rods at intervals around them. A candle-holder fits upon the bottom of the lower band, and is adapted to be fastened thereto and removed at will. A cone-shaped cover fits upon the top of the upper band and covers the neck portion of the bottle. This cover is provided with the requisite escape for the heat from the lantern. A handle is attached to the upper ends of the rods connecting the two bands together.

No. 20908.—24th March, 1906.—WINDOW GLASS MACHINE COMPANY, of Farmers’ Bank Building, Pittsburg, Pennsylvania, United States of America (assignees of John Henry Lubbers, of 506 McClintock Avenue, Alleghany County, Pennsylvania aforesaid, Glass-worker). Method of and apparatus for drawing hollow-glass articles.

Extract from Specification.—This invention relates to the drawing of hollow-glass articles, and is designed to provide for chilling the interior of the hollow article at or near the drawing-point, thereby enabling articles of thicker glass to be drawn than where outside chilling is used, and also equalising the heat of the molten bath of glass, which is more liable to chill in its outer portions. The inside chilling also enables the glass to be drawn at greater speed than formerly, and is of especial advantage where heat is applied to the bottom of the pot. The invention is designed to chill the glass by air or gaseous fluid, which is introduced through the bait, the air being supplied at the same level, or substantially the same level with respect to that of the glass bath, throughout the drawing operation. By thus supplying the air its effect in chilling is substantially uniform throughout the drawing, and the chilling effect is much stronger than where the air is introduced through a central hole in the pot. The invention is further designed to provide for withdrawing the hollow article and the supply-tube from each other after the drawing operation is completed, this being preferably accomplished by drawing the supply-tube upwardly out of the article after the drawing of the glass article is completed. The invention also relates to the exhaust or relief of a small portion of the air supplied to the interior of the article during drawing through a small hole which is opened by the operator after the forming of the cap, so that a constant opening is provided through which the excess air is passed out as it becomes heated within the article. This has been found desirable, especially in connection with a graduating valve by which the supply of the air is controlled, since the small outlet prevents the gradual enlarging of the article during drawing, which is otherwise liable to occur.

No. 20927.—30th March, 1906.—CARL ADOLF FREDRIK RAMSTRÖM, of Observatoriegatan, 21 Stockholm, Sweden, Clerk. Improvements in liners for centrifugal liquid-separators.

Extract from Specification.—This invention relates to an arrangement in the plates, the discs, or the partition walls of liners for centrifugal liquid-separators, especially centrifugal milk-separators. The plates, discs, &c., may be mounted at the side of each other, or above each other, or they may be arranged in any other known manner or in a new manner to form together a body, filling the drum to a greater or less extent, and provided with a plurality of narrow spaces or cavities occupied by the liquid. The said plates, discs, &c., may have a bent, curved, broken, or any other suitable shape, or they may be straight and mounted in an oblique position in the drum, or arranged in any other manner so that they divide the radius of the drum or a line parallel to the axis of the drum into short pieces. The said arrangement consists in the acting surfaces of the said plates, discs, &c.—i.e., the surfaces of the same with which the liquid is in contact—being finely rifled or toothed (channelled) with the rifles mounted so close to each other that they are separated from each other only by a very thin rib, sharp-edged if necessary. By the said arrangement, especially if the rifles are formed by a pressing operation, the plates, &c., will be strengthened, so that they can be made very thin and light, the effect being besides increased very considerably. Either the one side of the plates, discs, &c., may be rifled, while the other side is smooth, or both the sides may be rifled. The arrangement last mentioned forms an essential part of this invention, especially if the rifles in the one side cross the rifles in the other side.

No. 20954.—4th April, 1906.—FREDRIK WAGNER, of Vasagatan, 42 Stockholm, Sweden, Merchant (assignee of Henrik August Bertheau, of 6a Urvädersgrand, Stockholm, Sweden, Engineer. Improvements in explosion-motors.

Claims.—(1.) In such explosion-motors, in which air and fuel are sucked in by the one and same valve, a device serving to separate the air from the fuel at the suction, so that the fuel does not accompany into the cylinder, but remains in the ignition and evaporation chamber communicating with the cylinder, characterized thereby, that between the comparatively spacious chamber and the valve is placed a screen or partition-wall in such a manner that the fuel let in through the valve is compelled to enter the ignition and evaporation chamber for mixing with the therein entering combustion air when the motor makes its compression stroke. (2.) In such explosion-motors as claimed in Claim 1, the arrangement that the ignition body, consisting of some fire-proof, heat-absorbing material, suitably soapstone, is enclosed in one or more, also suitably soapstone, casings in such a manner that there is free passage and communication around respectively between the inner ignition body and the surrounding casings, of which the outer one is surrounded by the ignition chamber, for the purpose of keeping the ignition body protected against being cooled off. (3.) A constructional form of the arrangement claimed in (2), characterized thereby, that the innermost placed ignition body (a) as well as the nearest surrounding casing (c), made, for instance, of soapstone, are constructed as in each other placed cylinders, provided with studs or flanges (b), respectively (d), and suitable admission orifices (i) for the driving-gas mixture.

No. 20957.—2nd April, 1906.—OTHO CROMWELL DURYEA, of 2903 Dalton Street, Los Angeles, California, United States of America, Mechanic, and MORRIS COLUMBUS WHITE, at present residing at Clun House, Surrey Street, London, England, Mechanical Engineer. Improvements in or relating to the fuel and lubricant supply for internal-combustion engines.

Claims.—(1.) In an internal-combustion engine, feeding the lubricant into the explosive mixture. (2.) In an internal-combustion engine, the combination with a fuel-inlet 12 of a lubricant-inlet 13, whereby the lubricant is introduced into the air-passage and the whole mixed and supplied together to the engine. (3.) In an internal-combustion engine, the combination with a fuel-inlet (12) of a lubricant-inlet 13, both fuel and lubricant being drawn in by the air with the charge passing through a passage 11. (4.) The combination with an internal-combustion engine of a carburetter or vapouriser pivoted for the purpose described. (5.) In an internal-combustion engine, fuel or lubricant feeding mechanism automatically or otherwise adjustable relatively to the engine for the purpose described. (6.) The combination with an internal-combustion engine of a fuel-receptacle such as 5 adjustable relatively to the engine and attached thereto, substantially as described. (7.) The combination with an internal-combustion engine of a pivoted fuel-receptacle 5, a lubricant-receptacle 6, and regulating and vapourising mechanism co-operating therewith, sub-
