(10.) In an improved stump-and-root-grubbing machine, the combination of a king-bolt mounted upon the axle of the front driving-wheels and revolubly arranged within the headstock of the machine, a locking-pin for the retention of same, a draft hook, and a spring link, arranged together substantially as described and illustrated. (11.) In an improved stump-and-root-grubbing machine, a hauling-rope arranged to pass from the front of the machine over or round pulley-blocks and sheaves connected respectively with the purchase-bars and the main lifting-lever, as and for the purposes set forth. (12.) In an improved stump-and-root-grubbing machine, the combination of a draft gear and a hauling-rope, arranged substantially as described and as illustrated. (13.) In an improved stump-and-root-grubbing machine, a spring link for automatically disengaging the draft hook whereby the strain on the draft gear is transferred directly to the hauling-rope, as and for the purposes set forth. (14.) In an improved stump-and-root-grubbing machine, the combination of a hauling-rope, purchase-bars, and main lifting-lever, which is mounted upon a fulcrum, and arranged substantially as described. (15.) The general construction of a stump-and-root-grubbing machine, characterized by a main lifting-lever mounted upon traction-wheels (by intermediate mechanism), and having a lifting-arm or lifting-lever arranged so as to penetrate the ground when in operation for stump-extracting purposes. (16.) The general construction of a stump-and-root-grubbing machine, characterized by a main lifting-lever mounted upon traction-wheels (by intermediate mechanism), and having a lifting arm or lifting-lever arranged so as to be elevated above the ground when the machine is in transit. (17.) The specified improved stump-and-root-grubbing machine, comprising the parts above described, and as illustrated in the drawings, as and for the purposes set forth as a combination of parts.

No. 15760.—15th December, 1902.—WILLIAM MCKENZIE, of Isla Bank, New Zealand, Farmer, and JOHN R. BELL, of Groper’s Bush, New Zealand aforesaid, Farmer. Attachment to lever lifting-jacks.

Claim.—In lever lifting-jacks, a link surrounding the standard and connected by means of a rigid rod to the handle end of the lever, in combination with a series of transverse teeth or serrations upon the front face of the standard with which the link is adapted to engage, as specified.
(Specification, 2s.; drawings, 1s.)

No. 15762.—12th December, 1902.—FREDERIC MOORE, of Lynwood, Marrickville Road, Marrickville, New South Wales, Draughtsman. Oil and grease separator.

Claims.—(1.) In apparatus for separating oil or grease from water, a tank provided with partitions alternately starting from the top and the bottom of the tank, those partitions starting from the top not reaching to the bottom of the tank, and those starting from the bottom not extending much beyond a point midway between the top and bottom, whereby the mixture of oil and water passing between these pairs of partitions shall receive a “send” upwards to a point where most of the oleaginous particles will remain, as set forth. (2.) In apparatus for separating oil or grease from water, a tank provided with alternate baffle-plates extending from the top to near the bottom of the tank and from the bottom to a point approximately midway to the top of the tank, in combination with a spreader-plate to meet the inflow of water and adapted to spread such water in a film over the plate, as specified. (3.) In apparatus for separating oil or grease from water, a tank provided with alternate baffle-plates extending from the top to near the bottom of the tank and from the bottom to a point approximately midway to the top of the tank, in combination with side cocks placed at or about the normal level of the water within the tank and adapted to draw off the superfluous oil or liquid grease which may be separated and lie on the surface of the water, as set forth. (4.) In apparatus for separating oil or grease from water where the inflow is intermittent and comes with a rush, a series of baffle-plates extending from the top of the tank, the preceding plate having a larger aperture beneath it than the next plate in the series, and so on to the last plate, in combination with a series of baffle-plates projecting from the bottom of the tank, but not reaching much beyond the mediate line of the tank, as specified. (5.) In apparatus for separating oil or grease from water where the inflow is intermittent and comes with a rush, a series of baffle-plates extending from the top of the tank, but not to the bottom, and an alternate series of baffle-plates extending upwards from the bottom of the tank to a point midway between the bottom and the top, in combination with a siphon in the last division of the tank, such siphon being adapted to siphon the water, but not the oleaginous matter, from the tank into the outflow-pipe, as and for the purposes specified.
