No. 18918.—6th January, 1905.—JOHN ST. CLAIR GUNN, of Bloomsbury, Kaikoura, Marlborough, New Zealand, Surgeon. Improved apparatus for intercepting and automatically rejecting contaminated rain water.

Claims.—(1.) Apparatus for the purpose indicated, consisting of the parts arranged, combined, and operating substantially as specified and illustrated. (2.) Apparatus for the purpose indicated, comprising, in combination, a cistern, a receiver pivotally mounted therein and projecting therefrom, a counterbalance for the receiver, the cistern receiving water from a roof and discharging it into a tank, the receiver being constructed and arranged to retain a small quantity of water when tilted against the action of the balance weight and to reassume its normal position when said water has evaporated, substantially as specified. (3.) In apparatus for the purpose indicated, the employment of a receiver pivotally supported beneath a down-pipe from a roof and arranged to tilt under the weight of water, the major part of its contents being thereby discharged, and the receiver remaining tilted until the remaining water is evaporated, when it reassumes its normal position, substantially as specified.

No. 18932.—10th January, 1905.—LUDWIG RISSMULLER, of Hotel St. George, 51, Clark Street, Brooklyn, New York, United States of America, Manufacturer. Process of extracting fatty substances from meat.

Claim.—The described treatment of meat for the purpose of the extraction of the fatty substances therefrom, which consists in subjecting the meat first to the action of an alkaline substance to effect an initial separation of the fatty matter from the fibrous matter and to prevent the clogging up the pores by coagulated albuminous substances, and then to the action of an acid to neutralise the alkali and to complete the separation of the fatty matter by the destruction of any soaps or emulsions formed during the first stage of the process.
(Specification, 4s. 6d.)

Claims.—(1.) In a centrifugal separator of the kind referred to, an outlet for the heavier liquid consisting of a slot or slots, such as d, in the drum neck, and an outlet for the lighter liquid furnished with a screw, such as j, situated in the separating hood, substantially as described, and for the purposes set forth. (2.) In a centrifugal separator of the kind referred to, the combination with a slot or slots for the discharge of the heavier liquid, of a plate, flange, or collar, such as m, substantially as described, and for the purpose specified. (3.) In a centrifugal separator of the kind referred to, the combination with a regulating screw through which the lighter liquid is discharged, of members, such as h and l, disposed at the inner and outer sides of the separating hood and screwed to receive the said screw, and the member h having a slot, such as g, for the passage of the lighter liquid, substantially as described. (4.) A centrifugal separator of the kind referred to, having the outlets for the separated liquids arranged and constituted substantially as described with reference to, and as illustrated by way of example in, the drawings, and for the purposes specified.

No. 18934.—10th January, 1905.—JAMES BARCLAY JACKSON, of Gisborne, New Zealand, Road-overseer. An improved road-plough.

Claims.—(1.) In road-ploughs, a share formed of a metal plate, the forward end of which is pointed, bent longitudinally along its middle into right-angled triangle form, substantially as specified. (2.) In road-ploughs, a share formed of a metal plate, the forward end of which is pointed, bent longitudinally along its middle into right-angled triangle form, and provided with sleeves within the angle, corresponding sleeves upon the bottom ends of legs depending from the plough-beam and a rod passing through such sleeves and those upon the share, substantially as specified. (3.) The general arrangement, construction, and combination of parts in my improved road-plough, as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 18946.—12th January, 1905.—JOHN WESLEY DICKINSON, Jun., of 409-411, East Markham Street, Little Rock, Arkansas, United States of America, Secretary and Treasurer of the Dickinson Ball-bearing Wheel and Vehicle Company. Improvements in and relating to ball-bearing vehicle-hubs.

Claims.—(1.) The described process of constructing a wheel for anti-friction bearings which consists in forming the rims of the flanges of a greater thickness than they are to be in the finished wheel, securing the rim of the wheel in a plane and boring a hole through the hub at absolutely right angles to the plane and at the centre of the wheel, truing the interior and exterior surfaces of said rims by removing a portion thereof so as to be perfectly true relatively to the axis of the hole through the hub, then turning the wheel over, and truing the interior and exterior of the rim by removing a portion thereof so as to be perfectly true with the axis of the said hole. (2.) In a ball-bearing, two sleeves, one within the other, the inner sleeve being provided with a cone adjacent to each end and the outer sleeve having the ends thickened and interiorly screw-threaded a part of the length of each end, a ball-cup loosely mounted in the non-threaded portion of each end so as to be moved longitudinally of the bearing, an exteriorly screw-threaded lock-nut within the screw-threaded portion of the outer sleeve, and dust-proof mechanisms. (3.) In a ball-bearing, two sleeves, one within the other, the inner sleeve being provided with a cone adjacent to each end and each end of the outer sleeve being interiorly screw-threaded for a short distance, a ball-cup in each end beyond the screw-threaded portion, means for locking said cup against rotation but permitting free movement longitudinally of the axis of the bearing, and an interiorly screw-threaded lock-nut within the screw-threaded portion of each end of the outer sleeve, and dust-proof mechanism. (4.) In a ball-bearing, two sleeves, one within the other, the inner sleeve being provided with a cone adjacent to each end, and each end of the outer sleeve being interiorly screw-threaded for a short distance and provided with a groove at right angles to said screw-threads and extending inward beyond the same, a ball-cup in each end beyond the screw-threaded portion, the periphery being provided with a projection for entering said groove, an exteriorly screw-threaded locking-nut within each screw-threaded portion of the outer sleeve, and dust-proof mechanism. (5.) In a ball-bearing, two sleeves, one within the other, the inner sleeve being provided with a cone adjacent to each end, and each end of the outer sleeve being screw-threaded for a short distance, a ball-cup loosely but non-rotatably mounted in the non-screw-threaded portion of each end, an exteriorly threaded locking-nut within the screw-threaded portion of the outer sleeve, the outer face of it being recessed and provided with means for rotating the nut, and a yielding washer mounted in said recess with its inner edge in engagement with the inner sleeve. (6.) In a ball-bearing, two sleeves, one within the other, the inner sleeve being provided with a cone adjacent to each end, and each end of the outer sleeve being interiorly screw-threaded a short distance, a non-rotatable ball-cup loosely mounted in the non-screw-threaded portion of each end, a lock-nut in each screw-threaded portion, a dust-cap in each screw-threaded portion outside of the lock-nut, the inner face of the rear lock-nut being recessed, a leather washer in said recess, the inner edge of which overlaps the inner end of the inner sleeve, and a yielding washer between said leather washer and the lock-nut at that end.

Improvements in alternating-current wattmeters.

Claims.—(1.) For an alternating-current wattmeter of the induction type, an iron core having a main polar projection for the shunt coil, projections of different polarity between which and the main polar projection there are comparatively small air gaps, and other polar projections having their faces respectively opposite the air gaps for the series coils, substantially as described. (2.) In an alternating-current wattmeter of the kind described, means for securing quadrature between the portions of the shunt magnetic flux and the series magnetic flux which pass through the meter disc, consisting of a sheet of conducting-material located between the shunt and series pole pieces and radially adjustable with respect to the meter disc, substantially as described. (3.) In an alternating-current wattmeter of the kind described, a closed coil having one side adjustably located in an air gap in the magnetic core of the shunt coil, substantially as and for the purpose specified. (4.) In an alternating-current wattmeter, means for adjusting the distribution of the flux in the core of the shunt coil, substantially as described. (5.)
