metallic casing. (2.) In a candle-protector, a cap as specified in claim 1, in which the metallic ring encircling the candle is joined to the casing by a metallic cone, which latter thus forms a receptacle for melted wax. (3.) In a candle-protector, a cap as specified in claim 1 or 2, in which the upper edge of the casing is turned in in proximity to the flame, substantially as and for the purpose described. (4.) In a candle-protector embodying a cap and guiding-means for same as specified in claim 1, a perforated socket for the foot of the candle, the cap being so arranged that, when the candle is almost consumed, it forms with the socket a chamber in which the stump is melted, and from which it flows out through said perforations. (5.) A candle-protector comprising, in combination with a gravity-operated candle-cap forming a well for the melted wax, a frame such as a carrying a guide-rod, said cap sliding on said rod and being prevented from rotating thereon by engagement with the frame, said frame also carrying a socket for the candle-foot, substantially as described. (6.) A candle-protector, as specified in claim 5, comprising supporting-means and fixing-means, substantially as described. (7.) The improved candle-protector, substantially as described and illustrated.

No. 22396.—6th February, 1907.—WILLIAM McEACHERN, of Rosewood, New South Wales, Australia, Civil Engineer. Improvements in measured-charge delivery-device.*

Claims.—(1.) A container or feed-device, having side openings and a bottom opening, with over (and wider than) said bottom opening a shield having sloping sides, in combination with a slide having apertures to receive each an equal measure of goods, each slide movement inward or outward being limited by stopping-means and enabling delivery of goods through the said bottom opening. (2.) A container or feed-device having side openings and a slide to pass through them, the slide and the container-bottom being apertured as described, and the slide projecting beyond the container, as described and illustrated. (3.) A container or feed-device, having a slide for withdrawing measured quantities of goods, and an apertured base which projects from the container, substantially as described and illustrated. (4.) The appliance as illustrated in Fig. 1, as described, for the purposes set forth. (5.) The appliance as illustrated in Fig. 2, as described, for the purpose set forth.

No. 22408.—8th February, 1907.—GEORGE FELL HUTCHINSON, of Kapuni, New Zealand, Farmer. An improved hydraulic vacuum pump.*

Claims.—(1.) Means for obtaining a vacuum, the same consisting of a cylinder or cylinders connected with the vessel from which the air is to be drawn, in combination with means for causing a current of water to flow through each cylinder, and a valve for each cylinder adapted to alternately open and close the inlet end thereof, substantially as specified. (2.) Means for the purpose indicated, consisting of a water-conveying trough, vertical cylinders opening at their top ends into the trough and connected at their bottom ends to inclined pipes, pipe connections governed by outflow-valves between the cylinders and the vessel from which the air is to be drawn, and a valve mounted above the top end of each cylinder and adapted to fall and close such end and to be raised and open it, substantially as specified. (3.) In means for the purpose indicated, in combination, a water-trough, a pair of vertical cylinders extending downwards from the bottom of the trough, a rocking-beam pivoted above the cylinders, a rod depending from each end of the beam, a valve on each rod adapted to fit over and close the top end of the cylinder beneath it, connections between the cylinders and the vessel from which the air is to be drawn, and outflow-valves governing each of such connections, substantially as specified. (4.) The general arrangement, construction, and combination of parts in my improved hydraulic vacuum pump, substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 22487.—28th February, 1907.—ARTHUR STANLEY HUDSON, care of A. H. Hudson, 303 Queen Street, Brisbane, Queensland, Australia, Station Employee. Improvements in pliers for marking the ears of sheep and other animals.*

Claims.—(1.) In improvements in pliers for marking the ears of sheep and other animals, means consisting of fixed lower and movable upper jaws parallel to each other, and carrying male and female cutters respectively (removably attached thereto), operated by means of a pair of handles pivoted one to the other, as described, and as illustrated in the drawings. (2.) In improvements in pliers for marking the ears of sheep and other animals, means by which the jaws are caused to move parallel when being opened and closed, consisting of a guide and guide-pin and bearing-surfaces on the support to which the upper handle is pivoted, as described, and as illustrated in the drawings. (3.) An improved plier for marking the ears of sheep and other animals, consisting of a pair of parallel jaws carrying removably attached male and female cutters, handles for operating same, means for causing the jaws to move parallel when in operation, and a spring or springs for keeping the jaws normally open, as described, and as illustrated in the drawings.

No. 22506.—4th March, 1907.—ROBERT EDWIN REARDON, of 388 Rideau Street, Ottawa, Ontario, Canada, Inventor. Improvements in sights for fire-arms.

Extract from Specification.—My invention consists, broadly, in a bar to be applied to the leaf or standard of various types of rifle-sights, and it comprises: 1st, a wind-gauge having an adjusting-device consisting of a screw having a head so shaped that upon the turning of the same an adjustment equal to degrees or fraction of degrees may be indicated by the sense of touch; 2nd, a vertical adjustment of the eye-piece, also by means of a screw having the same features as that of the wind-gauge, the range of adjustment being made to extend to a maximum of 100 yards or more above or below the point to which it has been set; 3rd, a sighting-piece carrying two sighting-apertures so positioned that one of the apertures may be used when the sight is in the vertical or horizontal position; 4th, a sighting-aperture of a U- or V-shaped form, centrally positioned on the diameter or chord of a half-circle or segment.

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

No. 22513.—6th March, 1907.—WILLIAM ARTHUR CALDECOTT, of Consolidated Goldfields Building, Simmonds Street, Johannesburg, Transvaal, Metallurgist. Improvements in means for effecting the separation of liquids from crushed-ore products.*

Extract from Specification.—This invention appertains to the separation of liquids (water, cyanide or other solvent solutions, water washes, and the like) from crushed-ore products. The invention is designed more particularly for effecting the direct continuous separation of sand (the coarser and heavier particles of pulverised ore) from the mill pulp or crushed ore in a condition suitable for treatment in the leaching-vats. The invention in part is also applicable for effecting the separation of gold-bearing solutions from pulp containing ore-slime and sand, or ore-slime or sand, or for clarifying the gold-bearing cyanide-solutions or water from suspended solid matter preparatory to the precipitation of the precious metal from such solutions or water, or for any other analogous purpose. According to my invention, as applied more particularly to the separation of sand from mill pulp, or when the mixture to be treated contains a large percentage of solids, I first treat the pulp or mixture in an apparatus designed for continuously effecting the removal of the bulk of the liquid and slime from the pulp, and subsequently effect the separation of the remaining liquid by means of suitable filtering apparatus. Instead of running the whole or part of the pulp entering a cyanide-works into the ordinary sand collecting or settling vats, as is presently the practice, this pulp may be run into one or more of the apparatus for removing the bulk of the liquid and slime, and the concentrated residue, consisting of the sand and a small proportion of the slime, be delivered direct to the filtering apparatus, whereby the greater portion of the remaining liquid will be separated, and the moist residue be in a suitable condition for immediate and direct treatment in the leaching-vats.

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