exerted on a given piece or lump is substantially in proportion to the work required. The piece or lump being thus broken up, its parts promptly move forward to the next zone of reduction, and so on until the desired disintegration is reached. The ultimate size of the particles, to which a given material is reduced, depends in general upon the amount of impact and attrition to which the material is subjected. This is best regulated by varying the number of reducing zones, or the rate of passage of the material there-through, or both, as will be more fully explained.

Claims.—(1.) In race-starting machines, the combination with a tape or barrier attached at its ends to links slidably mounted upon vertical guide-rods secured to posts arranged on the respective sides of the track, of a cord suspended over a pulley upon the top of each post and at one end attached to the corresponding link and at its other end to a weight and elastic or spring connection, and means whereby the links may be held at the lower ends of the guide-rods, and may be simultaneously released, substantially as and for the purposes specified. (2.) In race-starting machines, the combination with a tape or barrier attached at its ends to links slidably mounted upon vertical guide-rods secured to posts arranged on the respective sides of the track, of lever hooks pivoted one on each post adapted to engage with the respective links and hold them at the lower ends of the guide-rods, cords attached to such hooks and carried upon pulleys to one of the posts, a hand-lever pivoted on such post to which the cords are secured, and means whereby the links may be drawn up the guide-rods when released from the hooks, substantially as specified. (3.) The general arrangement, construction, and combination of parts in my improved starting-machine for horse-races, substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 24875.—2nd September, 1908.—JOHN CHARLES PRESTON, of No. 255 Sussex Street, Sydney, New South Wales, Australia, Civil Engineer. Improved incandescent-oil lamp.

Claims.—(1.) An improved incandescent-oil lamp, comprising an oil contained with air-compressing device therein or thereon, a pillar tube terminating in a ring or vaporising tube and discharge nozzle or nipple, a U-shaped mixing-tube over said nipple discharging in an incandescent mantle, and a hood and guard and mantle-holding ferrule supported by the ring and vaporising-tube, substantially as described and explained. (2.) The combination and arrangement altogether of the parts or integers for the purposes set forth, forming an improved incandescent-oil lamp, substantially as described and explained, and as illustrated respectively in Figs. 1, 2, and 3, and in Figs. 1, 2, and 4 of the drawings.

No. 24880.—3rd September, 1908.—FREDERICK COTTERELL, of 43 Lonsdale Street, Melbourne, Victoria, Australia, Glass-beveller. Improvements in glass-bevelling machines.

Extract from Specification.—Undergear that will give the required rigidity and support beneath the grinding-edge of the machine-table whilst the glass is being bevelled by means of grinding-discs, and at the same time allow of any angle of bevel to be ground perfectly straight, smooth, and uniform on the sides or edges of plate or sheet glass. And as my second improvement: Overhead gear carried by a suitable framing and provided with weighted balance levers so that the grinding pressure can be controlled and regulated on the sides or edges of the glass whilst being bevelled, and, further, means for adjusting certain parts of the overhead gear so that the grinding-discs may make any required width or size of bevel on the sides or edges of the plate or sheet glass.

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