[No. 85

lever is operated to force out one of a number of tickets pressed together by a spring, a connecting-rod from said hand-lever arranged to oscillate a portion of a tube and deliver a ball to a race conducting said ball to indicating-mechanism, two wheels in said mechanism arranged opposite to each other in the same plane and having corresponding recesses in their peripheries, means for revolving one of said wheels from any convenient source of power whereby the ball carried in a recess in the revolving wheel moves the other wheel through part of a revolution, motion being imparted thereby to drums or rollers having numbers upon their circumferential peripheries indicating the number of times the hand-lever has been operated and consequently the number of backers of a competitor, substantially as and for the purposes specified. (3.) The combination, in apparatus for the purpose described, of an inclined race to which an official issuing a ticket upon a competitor delivers a ball from a containing-hopper, said ball travelling in said race to a shute or tray from which it is delivered upon the periphery of a wheel having recesses each adapted to receive one ball, the wheel being constantly revolved from any convenient source of power, a second wheel having its periphery opposed to the first and having similar recesses in its periphery arranged at similar pitch, said second wheel being normally stationary but caused to move through part of a revolution when the revolving wheel carries a ball in one of its recesses so that it engages in one of the recesses in said second wheel, and indicating-apparatus operated by the movement of the second wheel, substantially as specified. (4.) The combination, in apparatus for the purpose described, of an inclined race to which an official issuing a ticket upon a competitor delivers a ball from a containing-hopper, said ball travelling in said race to a shute or tray from which it is delivered upon the periphery of a wheel having recesses each adapted to receive one ball, the wheel being constantly revolved from any convenient source of power, a second wheel having its periphery opposed to the first and having similar recesses in its periphery arranged at similar pitch, said second wheel being normally stationary but caused to move through part of a revolution when the revolving wheel carries a ball in one of its recesses in said second wheel, and indicating-apparatus operated by the movement of the second wheel, an inclined shute conveying said ball passing from said wheels to similar wheels in similar mechanism provided to indicate the total number of backers of all competitors, substantially as specified.

No. 13187.—23rd November, 1900.—HENRY JAMES JONES, Engineer, and JOSEPH BAKER, Watchmaker, both of Stratford, New Zealand. Improvements in the generation of acetylene gas, and in appliances therefor.*

Claims.—(1.) In acetylene-gas generators, a cylindrical water tank or chamber whose top end is open and whose bottom end is tapered downwards and is provided with a removable slime-chamber in combination with a bottomless gas-generator and holder fitting within the tank, a cage or basket suspended within the generator or holder, a feeding-tube in the centre thereof, and an outlet-pipe leading from the holder to the outside of the appliance, all as and for the several purposes specified. (2.) A generator of acetylene gas consisting of a bottomless chamber fitting within a water tank or reservoir, such generator having a basket or cage suspended within it upon rods closely fitting within sleeves secured to the top of the generator, the top ends of the rods being secured together by means of a cross-piece, as specified. (3.) A generator for acetylene gas consisting of a bottomless chamber fitting within a water tank or reservoir and provided with a basket or cage suspended therein, in combination with a central feeding-tube secured to the top of the generator and whose bottom end opens into the basket or cage therein, such feeding-tube being provided with means whereby the top and bottom ends may be opened or closed simultaneously, as set forth. (4.) The general arrangement, construction, and combination of parts in our appliances for the generation of acetylene gas as described and explained, as illustrated in the drawing, and for the several purposes set forth.
