No. 24302.—24th April, 1908.—GUSTAF EMIL OHRN, of Herrang, Hafverosund, Sweden, Engineer. Improvements in apparatus for magnetic separation of ore.

Claim.—Apparatus for separating ores magnetically, in which the ore-pulp is made to flow in the upper part of a comparatively deep current horizontally past and in proximity with a multipolar system of magnets, but is separated therefrom by a moving non-magnetic screen, which is out of contact with the stream of water, whereby the most magnetic particles are drawn upwards out of the water to the said moving screen and carried along some distance thereby, while the less magnetic particles are floated along the surface of water under the attraction of the magnets, and thereby separated from the non-magnetic particles, which sink downwards, substantially as described.

(Specification, 2s. 9d.; drawing, 2s.)

No. 24311.—8th June, 1908.—CLAUD H. WILLIAMS, of Muriwai, Auckland, New Zealand, Station-owner. An improved fencing-dropper.

Claims.—(1.) A wooden dropper for wire fences, having a series of channels in one face, each channel receiving one of the wires of the fence, and link wires one for each fencing-wire, each link passing through a hole in the dropper, and having its ends adapted to be bent over the fence-wire lying in the adjacent channel, substantially as specified. (2.) A fencing-dropper constructed, arranged, and operating substantially as specified and illustrated in the drawing.

(Specification, 1s. 9d.; drawing, 1s.)

No. 24318.—29th April, 1908.—DAVID EDWARD BIGELOW, of Equitable Buildings, Collins Street, Melbourne, Victoria, Australia, Mining Engineer. Improvements in revolving screens.

Extract from Specification.—A revolving screen consisting of a drum the periphery of which is composed of wire screen-cloth, having dished or concave sections in combination with means for feeding the ore or metallurgical products on to the upper outer surface of the said screen, with spray-pipes and means for removing the oversize products from the bottom of the said drum, and for removing the fines from the interior of the said drum.

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

No. 24337.—28th April, 1908.—ANNIE MARGARET PONNINGHAUS, of 30 Portland Place, South Yarra, Victoria, Australia, Married Lady. An improved apparatus relating to the heating of liquids.

Extract from Specification.—This invention includes a bottom-piece 2 forming a fire-grate (Fig. 2). Through the middle of this is a fire-bar hole 3. Within the interior of the said bottom-piece is a liquid-heating ring 4 through which liquid passes. Resting upon the said bottom-piece and near the fire-door hole are fire-bars 5. Beneath the said fire-bars is an ash-pan 6. Above the said bottom-piece is an upstanding sidepiece or lip 44 retaining the bottom of a shell 7. The said shell may be secured to the said upstanding sidepiece. The top of the said shell has thereon a cover 8. Inside the said shell, and therefore above the bottom-piece, is a fire-box 9. Above the said fire-box is a chimney or flue 10. Leading into the fire-box is a fire-door 11, &c.

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

(Specification, 8s. 6d.; drawing, 1s.)

No. 24338.—28th April, 1908.—ANNIE MARGARET PONNINGHAUS, of 30 Portland Place, South Yarra, Victoria, Australia, Married Lady. An improved machine for washing or otherwise treating clothes or other articles.

Extract from Specification.—On reference to the drawings it will be seen that there are included two side-frames marked 2. The said two side-frames are united by a crosspiece 3. To each side of the said crosspiece 3 are attached the inner ends of buffer-springs 4 (Fig. 1). The said buffer-springs 4 may extend to the buffer 5 hereinafter referred to, or they may be short as shown. Instead of spiral springs being used, plate-springs may be employed, or any suitable material having sufficient resiliency. Embracing portion of the top of each sidepiece is a top-piece 6. This is preferably secured to the side-frame by a bolt 7 (Fig. 1). Each top-piece has an opening or pocket 8 therein. In each opening are beds 9. Upon each bed rests one end of an upper pivot-pin 10. This pivot-pin consists of a piece of plain round metal passing into the opening 8, the ends of which pin rest, as stated, upon the said beds 9 and as shown in Fig. 2. The two top-pieces 6 at the wringer end of the machine—i.e., the end opposite the bow or other shaped operating-lever 11—have wringer-board lugs 12 thereon. To these is secured a wringer-board 13, to which may be attached a wringer of any well-known character. Suspended from each upper pivot-pin 10 is a link 14. This consists of a piece of rectangular-sectioned metal, the upper and lower ends of which have a half or three-quarters (more or less) round bend 15 thereon. Pivoted in the lower ends of the links 14 are lower pivot-pins 16. The said lower pivot-pins 16 pass through holes in the lower ends of droppers 17, the upper ends of which droppers are attached to the sides of the open-topped box 18 referred to, &c.

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

No. 24339.—28th April, 1908.—ANNIE MARGARET PONNINGHAUS, of 30 Portland Place, South Yarra, Victoria, Australia, Married Lady (assignee of Wilhelm Bartholdt Didrick Ponninghaus, of 30 Portland Place, South Yarra, Victoria, Australia, Machinery Importer). An improved machine for washing soiled or used articles.

Extract from Specification.—My invention (referring to Figs. 1, 2, and 3) includes a framework 1. This may be of any suitable conformation, and supports a rotatable barrel or drum 2. In the barrel or drum bottom is a draw-off plug 3. The top of the said barrel or drum is open, and around the top edge is a gutter or recess 4 in which reposes a ring of jointing material 5, such as cork. Protruding inwardly from the inner surface of the barrel or drum, and integral therewith or attached thereto, are two, three, or more water-elevators 6. Protruding outwardly from the outer surface of the barrel or drum, and integral therewith or attached thereto, and diametrically opposite each other, are lugs 7 and 8 (Fig. 1). Extending over the open top of the drum is a door or cover 9. Protruding outwardly from the outer surface of the said door or cover, and diametrically opposite each other, are lugs 10 and 11 (Fig. 1). The said door or cover rests upon the aforesaid jointing-ring 5 in the gutter or recess 4 of the barrel or drum, and is retained thereto by a hinging-clamp. On reference to Fig. 1 it will be seen that this consists of a bolt or threaded member 12 pivoted by a pivot-pin 13 within the aforementioned lugs 7 protruding from the barrel or drum. The said bolt or threaded member 12 passes between the aforementioned lugs 10 protruding from the door or cover, and is retained thereto by a wing or other nut 14. The door or cover 9 is locked to the barrel or drum 2 by a locking-clamp. On reference to Figs. 1 and 3 it will be seen that this consists essentially of an intermediately pivoted hook-pointed forked lever 15 having a crosspiece 16. The said lever is pivoted by trunnions 17 to an internally threaded nut 18, with which said trunnions are integral. In combination with the above is a bolt or threaded member 19 pivoted by a pivot-pin 20 within the aforementioned lugs 8 protruding from the barrel or drum. The said bolt or threaded member 19 passes between the aforementioned lugs 11, protruding from the door or cover, and is retained thereto by forcing the lever 15 from a horizontal plane into the position assumed in Fig. 1, &c.
