No. 22069.—13th November, 1906.—PETER MORICE, of Claude Avenue, Neutral Bay, North Sydney, New South Wales, Australia, Stonemason. Improved apparatus for utilising the force of the waves of the sea.

Claims.—(1.) In apparatus for utilising the force of the waves of the sea, a platform such as A, one or more cylinders (open at both ends) pendant therefrom, easy fitting pistons or discs within the cylinders, piston-rods rising vertically from the cylinders, and means for connecting the piston-rods with compression-pumps, as and for the purposes set forth. (2.) In apparatus for utilising the force of the waves of the sea, a platform such as A, one or more cylinders (open at both ends) pendant therefrom, means for adjusting the height of the cylinders below the platform to the varying height of the tide water, piston-rods rising vertically from the cylinders, means for connecting the piston-rods to compression-pumps, a tide-well such as L beyond the reach of the waves, a float and rod within the well adapted to rise and fall with the tide, and means for connecting the float and rod in the tide-well with the gear for adjusting the height of the cylinders whereby such adjustment may be effected automatically as specified. (3.) The general arrangement, construction, and combination of parts in the improved apparatus for utilising the force of the waves of the sea, as set forth and for the several purposes specified.

Claims.—(1.) In sash windows, indiarubber rollers arranged as described for the purpose described. (2.) In sash windows, struts as described in combination with a wedged key such as described which may be a twisting or sliding one, with plain or corrugated bearing surfaces, for the purpose described.

No. 22081.—21st November, 1906.—GEORGE GARIBALDI TURRI, of 364-366 Collins Street, Melbourne, Victoria, Australia, Registered Patent Attorney, &c. (nominee of Vermont Farm-machine Company, of Bellows Falls, Vermont, United States of America, Manufacturers — assignees of Perley Lovejoy Kimball, of Bellows Falls, Vermont, United States of America aforesaid, Manufacturing Superintendent). Centrifugal cream-separators.

Claims.—(1.) In a centrifugal cream-separator, a cover having an annular base and a tubular neck with an annular diaphragm therein, an annular disk of substantially the same diameter as the interior periphery of the bowl between the cover and liquid-subdividers in the bowl, with skim-milk passages between the disk and the cover-base, an annular projection and coincident packing-strip respectively upon the adjacent opposed surfaces of the annular diaphragm and the disk, a series of skim-milk passages located without the circumference of the annular projection and extending through the diaphragm into the tubular neck, cream-passages through the disk and diaphragm within the circumference of the annular projection and packing-strip, and a cream-discharge in the tubular neck below the skim-milk discharge-opening therein. (2.) In a centrifugal cream-separator, a cover provided with a tubular neck which has an annular diaphragm therein near its lower end, an annular disk of substantially the same diameter as the interior periphery of the bowl and located between the liquid-subdividers therein and the cover-base, a closed cream-chamber between the disk and the diaphragm in the neck, a radially adjustable cream-outlet through the disk into the cream-chamber, a passage from said cream-chamber through the diaphragm to cream-discharge opening in the side of the neck, and skim-milk passages between the disk and cover-base and through the diaphragm into the tubular neck. (3.) In a centrifugal cream-separator, a cover provided with a chambered neck and an annular diaphragm therein near the lower end of the chamber, an annular disk of substantially the same diameter as the interior periphery of the bowl and located between the liquid-subdividers therein and the cover, skim-milk passages extending from the bowl between the adjacent opposed surfaces of the disk and the cover-base and through the diaphragm to the chamber in its neck, a closed cream-chamber between the disk and diaphragm, the radial distance of the exterior limit of which chamber from the axis of rotation is within the radial distance from said axis of the skim-milk passages in the diaphragm, a radially adjustable cream-outlet through the disk into the cream-chamber, and a tubular passage from the cream-chamber through the diaphragm to a cream-discharge opening in the side of the neck. (4.) In a centrifugal cream-separator, a cover having a chambered neck with a diaphragm across its lower end, a disk within the bowl between the liquid-subdividers and the cover, a closed cream-chamber between the disk and the diaphragm, a cream-opening through the disk into the closed chamber, and a cream-outlet passage from the closed chamber through the diaphragm. (5.) In a centrifugal cream-separator, a cover having a chambered neck with a diaphragm across its lower end, a disk within the bowl between the liquid-subdividers and the cover, a closed cream-chamber between the disk and the diaphragm, a cream-opening through the disk into the closed chamber, and a cream-outlet passage from the closed chamber through the diaphragm to a discharge-opening in the neck.

No. 22082.—21st November, 1906.—GEORGE GARIBALDI TURRI, of 364-366 Collins Street, Melbourne, Victoria, Australia, Registered Patent Attorney, &c. (nominee of Vermont Farm-machine Company, of Bellows Falls, Vermont, United States of America, Manufacturers—the assignees of Perley Lovejoy Kimball, of Bellows Falls, Vermont, United States of America aforesaid, Manufacturing Superintendent). Centrifugal cream-separators.

Extract from Specification.—The mechanical means for facilitating the separation of cream and blue milk from each other consists of a peculiarly organized structure by which the mass of whole milk introduced into the centrifugal bowl to be therein operated upon is subdivided into what may properly be designated as “thin liquid fillets,” each separately inclosed in a correspondingly shaped compartment wherein the distance to be travelled by the cream globules in order to become separated from the blue milk with which they are associated is the least practically possible, while at the same time the structure itself when the apparatus is taken apart is capable of being readily separated into its component elements to such an extent as to expose their interior surfaces to easy accessibility for cleansing. The individual component element of this structure is a single subdivider consisting of a flat annular plate d, which has affixed to both of its opposite sides and projecting at right angles therefrom a cyclic series of parallel blades e forming involute curves, and which may be provided with perforations f through it between such blades. Several of these subdividers are superposed in such manner as to cause their opposed series of involute blades to interlock with each other, and thus to convert each space between two consecutive blades into two thin tubular spiral passages leading from the inner to the outer margins of the annular plates from which those blades project, &c.

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

Improvements in centrifugal separators.

Claims.—(1.) In a centrifugal separator, the bowl, and the liners located in said bowl one within the other, said liners being supported independently of one another at their upper ends by the inner wall of the separator-bowl, substantially as described.

(3.) In a centrifugal separator, the combination with the bowl and the liners located therein one within the other of a ring secured to the upper end of each liner, said rings having contact with the inner wall of the separator-bowl. (4.) In a centrifugal separator, the bowl, the cover therefor, and the feed-cone supported by the cover, the lower edge of said cone being outwardly flared, substantially as described. (5.)
