No. 10619.—26th May, 1898.—GEORGE BROUGHAM HUBERT AUSTIN, of 60, Armadale Road, Armadale, near Melbourne, Victoria, Architect. Improved mechanism for assisting in the propulsion of cycles.*

Claims.—(1.) My improved mechanism for assisting in the propulsion of cycles, consisting in the various mechanical devices constructed, combined, and operating substantially as described and explained, and as illustrated in the drawings. (2.) In mechanism for assisting in the propulsion of cycles, a saddle as A, carried by a short tube as a¹, resting upon ball-bearings as a² within a larger tube as B, and having a cross-bar as b, passing through slots in said tube B, and a screwed cap as b¹, substantially as described and explained, and as illustrated in Fig. 1 of the drawings. (3.) In mechanism for assisting in the propulsion of cycles, a tube as B, fitting loosely within the downwardly projecting tube, as C, of the frame of the machine, and having slots as b⁴, in which work rollers as b³, removable fixed in said tube C, and either with or without guide-wheels as b⁵, substantially as described and explained, and as illustrated in the drawings. (4.) In mechanism for assisting in the propulsion of cycles, a tube as B, actuated by the weight of the rider, and fitted near its lower end with a pallet or rack as B², engaging with studs as D¹ or cogs on a wheel as D, gearing directly or indirectly with the crank-shaft or hub of the drive-wheel, substantially as described and explained, and as illustrated in the drawings. (5.) In mechanism for assisting in the propulsion of cycles, a saddle as A, pivoted at its forward end as at A¹, and having its rear end connected to a pair of levers as A⁸, fulcrumed on the saddle-support, and having their front ends connected to a tube as B, extending into a downwardly projecting tube of the frame of the machine, substantially as described and explained, and as illustrated in Figs. 13 and 14 of the drawings. (6.) In mechanism for assisting in the propulsion of cycles, a tube as B, actuated by the weight of the rider, and extending into a downwardly projecting tube, as C, of the frame of the machine, and fitted at its lower end with a piston as F, working within a short cylindrical chamber as F¹, having an inlet-valve as F² and outlet-valve as F³ and pipe as F⁴, substantially as described and explained, and as illustrated in Fig. 10 of the drawings. (7.) In mechanism for assisting in the propulsion of cycles, a tube or tubes as B, actuated by the weight of the rider, and extending into the downwardly projecting tubes, as CC¹, of the frame of the machine, and connected to a lever or levers as B⁴, having a rack as B² engaging with gearing leading to the crank-shaft or hub of the drive-wheel, substantially as described and explained, and as illustrated in Figs. 15, 16, and 17 of the drawings. (8.) In mechanism for assisting in the propulsion of cycles, a tube or tubes as B, actuated by the weight of the rider, and extending into the downwardly projecting tube, as C, of the frame of the machine, and gearing at its lower end with a pinion, as D, upon a spindle carrying a quadrant rack gearing with a loose pinion upon the crank-spindle, with which it is connected through the medium of pawls or their equivalent, substantially as described and explained, and as illustrated in Figs. 18 and 19 of the drawings.

(Specification, 12s. 6d.; drawings, £1 7s.)

No. 10715.—21st June, 1898.—P. AND D. DUNCAN, LIMITED, of Christchurch, New Zealand, Implement-manufacturers. Improved levers and riding-gear for ploughs.*

Claims.—(1.) In any plough, a stud as 1, having attached to it a seat, a raising-lever, and a steering-lever, and fixed to the frame by plates and bolts or the like, substantially as and for the purposes described. (2.) In any plough, a bridle as 10, pivoted horizontally to the frame of plough, and having a chain or the like connecting it to the raising-lever, substantially as and for the purposes described. (3.) In any plough, a raising-lever pivoted on a stud—said stud being securely fixed to the plough-frame—having a lug as 18, or the like, to which a chain or other connection from the bridle shall apply the motive-power, or part thereof, for the purposes described. (4.) In any plough, the combination of a stud as 1, carrying raising- and steering-levers as 7 and 8, and seat as 4, with a bridle as 10, pivoted horizontally to the frame, and provided with a chain or the like connecting it to the raising-lever, substantially as and for the purposes described.
