Claims.—(1.) A machine for drilling, cutting, or splitting stones or rocks, and in which the drilling-device a, connected to a toothed sector r, which may be regulated horizontally and vertically at any point of the supporting column s, is movable horizontally or vertically according to the position of the said sector, and this by means of an endless screw fitted to the said drilling-machine, and gearing with the sector for the purpose of grooving and splitting rocks, as described and as shown. (2.) A drill consisting of several cutting-teeth, each of which is provided with an outer flat triangular face, two adjacent faces inclined inwardly, and an inner triangular face, as described, and as shown in the drawings. (3.) The application of the machine claimed in No. 1 for bringing down masses of rock, the machine after having made the groove being brought into position in order to drill the hole for bringing down the rock, and remaining in this position after having drilled the hole, the drill being replaced by a hammer l in order to cause the wedge to advance, placed in the axial line of the hole, so as to bring down blocks without the use of any explosive whatever, as described, and as shown in the drawings.

No. 14168.—28th October, 1901.—JOHN WILLIAM HARDLEY and SAMUEL HARDLEY, Jun, both of Ashburton, New Zealand, Plumbers, &c. An improved spouting-bracket.

Claims.—(1.) A supporting bracket for house spouting or guttering, consisting of an inner piece upon which the spouting or guttering rests, and an outer piece placed against the face of and fastened to the inner piece in such a manner that its tendency shall be to spring against the inner piece, such outer piece being formed on its outer extremity with a curved portion adapted to fit upon the curved outer edge of the spouting, as specified. (2.) A supporting bracket for house spouting or guttering, consisting of an inner and an outer piece secured together in such a manner that the tendency of the outer piece shall be to spring upon the inner, the extremity of the outer piece being formed with a curved portion and with an extension thereto, in combination with a stay-piece the bottom end of which is adapted to be fastened to the extension of the outer spring-piece, while the top end is adapted to be fastened to the roof or other part of the building, as specified.

No. 14327.—12th December, 1901.—DAVID HERLIHY, of Aorangi, Feilding, New Zealand, Farmer. An improved tank for measuring milk and other liquids.

Claim.—In means for measuring off milk and other liquids, a tank or receptacle provided with an inlet-pipe, a glass-covered slot extending throughout the height of the tank, and a gauge parallel with the slot with markings thereon corresponding to the capacity of the tank at different heights, as specified.
(Specification, 1s. 6d.; drawings, 1s.)

No. 14378.—30th December, 1901.—THE BRITISH CHARRIER WOOD-CARVING COMPANY, LIMITED, of 49, St. Mary Axe, London, England, Carved-moulding Manufacturers (assignees of Leon Constant Henri Charrier, of Vendome, Loir-et-Cher, France, Engineer). Improvements in wood-carving machines.

Extract from Specification.—The object of this invention is to provide an improved construction of such machines, wherein the various operations are performed in a more efficient manner than heretofore, with great certainty, and in such manner as to increase the output of the machine. To this end, and according to our invention, we provide the machine with a suitably supported and counterbalanced reciprocating beam, which is adapted to carry a number of independently working tools and pressers, whilst the said beam also serves to actuate other tools carried by the frame of the machine above the table, and the said beam also acts in conjunction with a movable part of the frame below the work to actuate other tools, and also to automatically clear said tools from the work independently of the movement of the beam, in order to be clear of the tools at the proper time. We also provide the machine with mechanism adapted to so coact with the other parts of the machine that the work is fed with greater ease and accuracy.
[Note.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the descriptive part of the specification is inserted instead.]

No. 14382.—30th December, 1901.—WILLIAM FREDERIC SINGER, of Bridgeport, Connecticut, United States of America, Inventor and Manufacturer. Refrigerating systems.

Claims.—(1.) In a refrigerating system, and in combination, a gas-compressor, a circulatory pipe-system leading into said compressor, means for removing the heat of compression, an expansion-valve in said pipe-system whereby expansion of the contained fluid is permitted and the portion of said pipe-system beyond said valve converted into a refrigerating coil or chamber, and means interposed between said compressor and said expansion-valve and connected with and operated by the reduced pressure in said refrigerating-coil for regulating the flow of fluid through the system, substantially as described. (2.) In a refrigerating system, and in combination, a gas-compressor, a circulatory pipe-system leading into said compressor, means for removing the heat of compression, an expansion-valve in said pipe-system whereby expansion of the contained fluid is permitted and the portion of said pipe-system beyond the said valve converted into a refrigerating coil or chamber, a fluid-controlling valve in said pipe-system between said compressor and said expansion-valve, and a tube connecting said refrigerating coil with said fluid-controlling valve whereby the flow of fluid through said system is automatically regulated by variations of pressure in said refrigerating-coil, substantially as described.
