MANWARING'S GEARING OF MOWING MACHINES.

THIS invention, by William Manwaring, of Banbury, is intended to avoid noise and secure durability in the gearing of machines in which space is limited, and it consists in constructing one or both wheels (but by preference one only), in any pair or pairs of wheels gearing into each other, as follows:-The patentee takes two metal discs, having opposite and corresponding recesses or perforations in or through their faces, near the periphery, arranged in a circle at equal distances from each other and from the centres of the discs, and connects such discs by means of teeth or pins of wood, or of any other non-metallic compressible substances, being either driven in, wedged, or otherwise secured by any known means; but prefers simply to drive them into such recesses, the discs being also braced together by bolts or cottars, if required. Each pair of discs so constructed will form a toothed or tumbler wheel, and is used to gear into another wheel of similar or of any other construction.

Figs. 1 and 2 are respectively a section and a plan of my improved wheel. The dotted lines a, a, all, and so on in the latter show the position of the teeth and the recesses, which may be of any other shape, as, for instance, round, oval, &c.; the dotted lines 6, 8, in the same figure, and the parts similarly marked in Fig. 1 represent the boss which keeps the two discs at the proper distances from each other, and through which the bolts or other fastenings c, et, all, connect or brace the said discs together; d is the eye of the wheel in which the axle is keyed; e, el, are the two discs; ff, fu, f, the recesses in the same, and g', g, two of the teeth driven into such recesses.
