(2.) In apparatus as claimed in claim 1, sprayers formed of nozzles plugged with concave-faced plugs at their lower ends, each with two converging perforations; the sprayers being provided with means for ready connection to the leading-pipes, and with perforated thimbles or strainers, substantially as described. (3.) In apparatus as claimed in claim 1, the employment around the sprayers of a suitable hood, substantially as described, and as shown upon the drawings by Figs. 8 to 10. (4.) The improved apparatus for spraying liquids on roads or the like, constructed, arranged, and adapted to operate substantially as described, and shown on the drawings.

No. 22375.—31st January, 1907.—GEORGE GIBBINS, of 32 Cowper Street, Footscray, Victoria, Australia, Plough and Implement Manufacturer. Improvements in multiple ploughs and like implements.

Claims.—(1.) In a multiple plough, a cranked axle such as O with vertical portion such as S and wheel-arm such as T (see Fig. 3 of the drawings) attached by any suitable means to or within the frame of the plough, as and for the purpose described. (2.) The sustaining-bracket secured upon the furrow side of the plough-frame adapted to carry the mechanism for lifting or lowering the ploughs in order to cut the desired depth of furrow, substantially as described, and as illustrated in the drawings. (3.) The mechanism illustrated in Fig. 3 comprised of the cranked axle O with vertical portion S and the wheel-arm T, combined with the bracket A¹, as and for the purpose described. (4.) The combination of a multiple plough-frame providing for the expansion or contraction of the ploughs laterally in relation to each other, a short horizontal cranked axle O, with vertical portion S for lifting or lowering the ploughs, a lever to operate the axle O, and a sustaining-bracket A¹ secured at the side of the plough-frame to carry the lever and appurtenances, substantially as described, and as illustrated by the drawings. (5.) The combination of (a) a multiple plough-frame providing for the expansion or contraction of the ploughs laterally in relation to each other, (b) a member consisting of a horizontal axle O, with vertical portion S, sleeved wheel-arm T, and means for oscillating same, (c) means for sustaining and carrying the said lifting and lowering mechanism, and (d) levers and means for adjusting the ploughs laterally and up and down, substantially as described, and as illustrated by the drawings. (6.) The combination and arrangement of parts constituting the improved multiple plough, substantially as described.

No. 22385.—5th February, 1907.—THOMAS JEFFERSON LOVERT, of No. 1518 Marquette Building, Chicago, Cook, Illinois, United States of America, Mining Engineer. Magnetic separator.

Claims.—(1.) A magnetic ore-separator consisting essentially of a rotary electro-magnet journaled in a frame and geared for rotation at a relatively high rate of speed, and a conveyer-belt passing over said magnet and geared to travel at a relatively low rate of speed to permit magnetic parts of the ore attracted to the belt by the magnet to be retained under the pole-changing influence of the rotating magnet, and thereby agitated to shake out non-magnetic material associated with it. (2.) In a magnetic separator, a rotary electro-magnet formed of a plurality of substantially cylindrical independently wound sections having a common axis of rotation upon which they are mounted in endwise relation. (3.) In a magnetic separator, a rotary electro-magnet formed of a plurality of substantially cylindrical independently wound sections having a common axis of rotation upon which they are mounted in endwise relation, each section being formed of a plurality of radially extending members coupled together in series. (4.) In a magnetic separator, a rotary electro-magnet formed of a plurality of substantially cylindrical independently wound sections having a common axis of rotation upon which they are mounted in endwise relation, each section being formed of a plurality of radially extending removable and replaceable separately wound members coupled together in series. (5.) In a magnetic separator, the combination with a rotary electro-magnet formed of a plurality of substantially cylindrical independently wound sections, of a conveyer-belt for concentrates, and supporting wheels for the belt journaled at opposite end portions of the magnet and between magnet sections. (6.) In a magnetic separator, the combination with a rotary electro-magnet and conveyer-belt movable at different relative speeds, of supporting means for the conveyer-belt comprising a chain belt underlying the conveyer-belt, and chain-belt-engaging wheels rotating upon the same axis as the magnet and operating to maintain the chain belt close to but out of contact with the magnet. (7.) In a magnetic separator, the combination of a rotary electro-magnet formed of a plurality of substantially cylindrical independently wound sections having a common axis of rotation upon which they are mounted in endwise relation, a conveyer-belt, driving mechanism for the said magnet and belt operating to move them at different relative speeds, and supporting means for the conveyer-belt comprising a chain belt underlying the conveyer-belt, and chain-belt engaging and supporting wheels journaled at opposite-end portions of the magnet to rotate upon the same axis as the magnet, and operating to maintain the chain belt close to but out of contact with the magnet. (8.) In a magnetic separator, a rotary electro-magnet formed with a series of members having core-shanks, a supporting shaft, and means for removably fastening said core-shanks at their inner ends to said shaft to extend radially with relation to the shaft.

No. 22386.—5th February, 1907.—ARTHUR PARSONS, of Clifton Shoe-works, Newtown, Leeds, York, England, Shoemanufacturer; JOHN ADAM MORTON, of Welford Place, Leicester, England, Leather-manufacturer; JOSHUA COOKSON WRIGHT, of 36 Cross Flatts Place, Beeston, Leeds, York, England, Boots-stores Manager; and BENJAMIN WRIGHT, of 11 Dorset Terrace, Leeds, York, England, Bootmaker. Improvements in and relating to machines for lasting boots and shoes.

Claims.—(1.) A boot and shoe lasting-machine in which the lasting operation is effected by the relative movement between the last and a resilient die or matrix, for the purpose specified. (2.) The aforesaid resilient die or matrix, comprising a frame conforming more or less to the contour of the last and carrying a sheet or membrane of indiarubber or other resilient material having an opening or cavity for the reception of the ankle portion of the last, for the purpose specified. (3.) The combination with the aforesaid resilient die or matrix of means for enabling the last to be forced into the said die or matrix, for the purpose specified. (4.) The hinged wiper-bars for causing the edges of the upper to be pressed on to the insole after the lasting operation, substantially as and for the purpose specified. (5.) In a boot and shoe lasting-machine of the kind set forth in claim 1, the hinged presser-bar adapted to apply the outer sole to the insole after the edges of the upper have been pressed on to the latter as aforesaid, substantially as described. (6.) The aforesaid frame of the resilient die or matrix formed in two parts, between which the edges of the interior cushion portion is held, in combination with means for readily connecting and disconnecting said frame to and from the machine, substantially as and for the purpose specified. (7.) A boot and shoe lasting-machine having its parts constructed, arranged, and adapted to operate substantially as described with reference to the drawings, for the purposes specified.

No. 22391.—5th February, 1907.—HORACE MOTE, of Balmain, Sydney, New South Wales, Australia, Engineer. An improved extension step-ladder.

Extract from Specification.—My invention consists in making the strut at the back of the ladder with rungs, and disconnectable from the front part thereof. When in use the strut is connected to the front part of the ladder by brackets having hooked ends adapted to engage rungs of the strut. When in use as a step-ladder the strut is prevented from spreading by its upper end extending above the brackets and abutting against the front part of the ladder. When it
