IMPROVEMENTN HAND MOWING-MACHINES.

Specilcation forming part of Letters Patent No. 47,022, dated March 28, 1865; Reissue No. 8,630, dated March 18, 1879; application filed February 6, 1879; l

To all lwhom 'it may concern Be it known that l, Gr. W. JENNINGS, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Hand Mowing-Machine; and Ido hereby declare that the'followin gis a full, clear, and exact description thereof, which will enahle others skilled in the art to make and use the same, referencebeinghad to the accompanying drawings, forming part of this specification, in which- Figure l is a plan or top view of my invention, partly in section, as indicated by the line a: m, Fig. 2. Fig. 2 is a side view of the same,

vpartly in section.

Similar letters of reference indicate like parts.

The nature of my invention consists in certain improvements in hand mowing-machines, in the gearing, and in protecting and incasing the gearing from the fine-cut grass, from dust, dirt, grit, or any obstructions which might injure, obstruct, or strain the gearing; also, in-

the construction of the main frame of the mower, so as to make a compact, ligh and strong machine, which shall be comp etely .under the control of the operator, and well adapted for the work for which such a machine is designed, all as hereinafter more fully described in the specification and pointed ont in the claims.

A represents an axle, having wheels B B' placed loosely on its ends. The wheels B B are hollow, forming box or cupped wheels.

The whole open face of the box-Wheel B is covered by a side coveringplate, b, which is permanently attached to the axle of the wheel.

The other wheel, B, may be similarly constructed; but it has no internal gearing.

bbare side covering-plates,which completely cover the open faces of the cupped or horl wheels, and protect completely the gearing within said wheels.

The side covering-plates, b b, are secured to the ends of the axle A by screws a. The side covering-plates, b b, are also each provided with a cap or flange, C, irmly secured to 'said side covering-plates, b, the caps C. wholly or partially covering the front and upper portion of the wheels B B.

The coveringplates b b are each provided with a handle, D".

The -wheel B is provided, at the inner surface of its rim c, with teeth or cogs d forming an internal gear, into which a pinion, gears, the latter having its axis e secured to the plate b.v (See Fig. 2.) The pinionD also gears into another pinion, E, whichis attached to or cast concentrically with a bevel-wheel, F, the latter being within wheel B, and placed loosely on the axle A.

The bevel-wheel F gears into a bevel-pinion, Gr, which is placed loosely on a shaft, H,the latter having its bearings in the plate b, and covered by the cap f, which also covers the p in'ion Gr at the outer side of b.

The pinion G is connected with the shaft H, when desired, by means of a toothed clutch, I;- or a friction-clutch may be used instead, and I consider the latter preferable. This'clntcli is operated by a lever, J, at the outer side of plate b, and the handle D", which is attached to it.

with a crank-pin, g, which is fitted and works in a vertical slot, h, in an upright lug, i, at one end of the sickle-bar L, the sickle being placed upon the ringer-bar M, which is .secured by bolts to lips j on the caps C.

From the above description it will'be seen that when the machine is shoved along and the pinion G is connected to the shaft E, a reciprocating movement will be communicated to the sickle, and it will be seen that a very rapid movement may be givenit by a very compact arrangement of parts; and it will further be seen that the finger-bar and sickle may be moved upward or downward from the axle A as a center withoutin the least affecting the sickle-driving mechanism.

rlhe operator, therefore, willhave full control over the implement, and may raise or debecome deranged by use.

. All the sickle-driving mechanism isfully covered and protected from dust, dirt, cut

grass, and other substances which would have The front end of the shaft is provided a tendencyY to choke orclog it and render breakage or a straining of the workingp'arts probable. f

Having thus described the construction and operation of my improved hand mowing-machine, what I clann as new, and desire to secure by Letters Patent, isl. The combination, in ahand or lawn mowing-machine, of two cupped or box wheels,

gearing within 'the periphery of the drivingwheel, covering-plates coveringI the Whole open face of said box-Wheels and gearing, and a cutting apparatus extending across the machine, and suspended at each end by said coveringplates from the axles of said wheels, substantially as shown and described.

. 2. The stationary side plates .fully covering the open faces of the cupped or hollow carrying-wheels, said covering plates being con- Vnected from side to side by a cross-rod exl 4. Ahand orlawn lnowing-machinein which f lare combined two supporting-wheels, one upon each slde of the machine, internal gearing for driving the cutting apparatus, side plates fully covering and protecting theinternal gearing,

a cutting device secured at both ends to said side covering-plates, and the handles for pushing the mower forward, also secured to said side covering-plates, substantially as shown and described.

5. The combination, in a hand or lawn mowing-machine, of the station ary side plates, fullyV covering the open faces of the cupped or hollow carrying-wheels, with a cross-rod extending from one side plate to the other, and to which both side plates are rigidly secured, and a cutting apparatus supported from and'also connecting said side plates, substantially as shown and described.

6. The combination, in a hand or lawn mowing machine, of the side covering lplates mounted on the axles of the main supportingwheels, and inclosin g and supporting the gearing, with the handles for pushing the mower forward secured to said side covering-plates.

7 The combination, in a hand or lawn mowin g-machine, of supporting-wheels upon each side of the machine, turning loosely upon their axles, internal gearing, side plates, fully covering and Vprotecting said internal gearing, axles rigidly secured to said side plates, and on which said supporting-wheels revolve, and a spur gear or pinion, also supported in posi- [tion by said side plates, and engaging with the cogs of the internal gearing, to produce the motion from which the cutting deviceis` driven.
