Claims.—(1.) In means for producing differential reciprocatory motion, a shaft to which rotary motion is conveyed, two wheels of different diameters rigidly mounted upon the shaft and each provided with teeth upon a portion of its periphery, the teeth of the smaller wheel being adapted to engage with the teeth of a rack that forms part of or is connected to the appliance to be reciprocated, while the larger wheel is adapted to engage with a small pinion when the teeth of the smaller wheel have passed over the rack, such pinion being secured upon a shaft loosely mounted in bearings, a spur wheel also secured upon such shaft, and engaging with the teeth of the rack, as specified. (2.) The improved means for operating pump-plungers and the like consisting of the different parts constructed and arranged in the manner described, and illustrated in the drawings, whereby a slow motion in one direction and a quick return motion is obtained without reversing the rotation of the main driving-shaft, as specified.

Claims.—(1.) A pair of poles placed one on each side of a racing-track and formed with vertical slots therein, sliding-pieces fitting within the slots, a tape stretched across the track and secured at its ends to the sliding-pieces, and means whereby the sliding-pieces and tape may be retained in their lowest position and be caused to travel upwards when released, as specified. (2.) A pair of poles placed one on each side of a racing-track and formed with vertical slots therein, sliding-pieces fitting within the slots, a tape stretched across the track and secured at its ends to the sliding-pieces, a cord one end of which is secured to a sliding-piece on one side and passes over pulleys on the tops of the poles to the sliding-piece on the other side (to which it is connected) downwards and round a pulley mounted upon the pole on that side and again upwards over other pulleys on the tops of the posts, a long helical spring one end of which is secured to the free end of the cord while the other end is secured to the ground, and means whereby the spring and cord may be held in tension and released therefrom, as and for the purposes specified. (3.) The general arrangement, construction, and combination of parts in my improved device for starting horse and other races, as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 13970.—5th September, 1901.—REUBEN SPARROW, of Richardson Street, South Melbourne, Victoria, Engineer, and NICOLAY FAHRENHOLTZ JENSEN, of 21, High Street, Malvern, near Melbourne aforesaid, Nurseryman. An improved hub-brake for cycles, automobiles, and other road vehicles.*

Claims.—(1.) An improved hub-brake for cycles, automobiles, and other road vehicles characterized by an adjustable grooved brake-wheel, a downwardly extending bracket and clip to which the lower end of a spring brake-band is clamped, a wire having a short shouldered sleeve fitting between lugs on the upper end of said brake-band, said wire having a mushroom-headed stud, all combined and arranged substantially as set forth. (2.) In a hub-brake for cycles, automobiles, and other road vehicles, a grooved friction brake-wheel having radially sliding screws or studs fitting into inwardly projecting sockets, said screws having grooved heads and fitted with rotating nuts bearing against the face of said sockets, substantially as set forth. (3.) In a hub-brake for cycles, automobiles, and other road vehicles, a spring brake-brand secured at its lower end to a bolt passing through and clamped to a downwardly extending bracket or arm and clip, the other end of said bracket or arm fitting over the spindle of the drive wheel, and clamped between the back fork and adjustable cup or cone. (4.) In a hub-brake for cycles, automobiles, and other road vehicles, a spring brake-band mounted on a bolt, passing through the lower end of a downwardly extending bracket or arm and clip and secured by a nut, and an idle pulley on said bolt under which the actuating wire passes, substantially as set forth. (5.) In a hub-brake for cycles, automobiles, and other road vehicles, a wire connected to a spring brake-band and having short lengths of adjustment-chain and a mushroom-headed stud or pin with outwardly bent lugs on the lower end adapted to engage the looped ends of a double link, substantially as set forth.
(Specification, 3s.; drawings, 1s.)

No. 14208.—11th November, 1901.—CHARLES AUSTIN BRIGGS, of Wellington, New Zealand, Accountant. Improvements in fire-escapes.*

Claim.—A fire-escape ladder composed of a number of treads of metal or other material, formed with flat surfaces on their sides, and of chains passing upon each side of each tread at both ends thereof, such treads being secured firmly to the chains by means of bolts passing through the sides of the treads and through the links of the chains on each side, as specified.

No. 14226.—14th November, 1901.—MURRAY CORRINGTON, of 40, Wall Street, New York, United States of America, Engineer. Improvements in automatic fluid-pressure brake-apparatus.

Claims.—(1.) In an automatic fluid-pressure brake-mechanism, the combination, with a train-pipe, an auxiliary reservoir, and a brake-cylinder, of a primary piston and valve controlling the release of air from said cylinder, and a means for causing said piston and valve to move to release-position, which consists of a valve-device for opening an exhaust-passage from one side of the primary piston and at the same time closing the passage by which fluid-pressure is normally supplied to the same side of the said piston. (2.) In an automatic fluid-pressure brake-mechanism, the combination, with a train-pipe, an auxiliary reservoir, a brake-cylinder, and a recharging-passage for charging air from the train-pipe to the reservoir while the brakes are applied, of a primary piston and a valve controlling the release of the brakes and a means for causing said piston and valve to move to release-position, which consists of a valve-device for opening an exhaust-passage from one side of said primary piston and at the same time preventing the pressure which flows through said recharging-passage from getting to the same side of said piston. (3.) In an automatic fluid-pressure brake-system, ports and passages in the triple valve adapted to register with ports and passages in a side plate bolted on to said triple-valve casing, or with ports and passages in a valve-mechanism attachment to be bolted on to the triple-valve casing in place of said side plate, so that with the side plate in position on the triple-valve casing the brakes may be operated in the usual way and released during the recharging of the auxiliary reservoirs; but when said valve-mechanism attachment is bolted to the triple-valve casing in place of the side plate, the auxiliary reservoirs may be recharged while the brakes are on, and the brakes may be positively released after the auxiliary reservoirs are so recharged, substantially as set forth. (4.) In an automatic brake-mechanism, means whereby the auxiliary reservoirs can be charged when the brakes are applied, and the brakes released after the reservoirs are charged, substantially as described with reference to the drawings.
