Hnite-d taten @aient (tilyia Letters Patent No. 95,864, dated October 12, 1869.

HARVESTER.

The Schedule referred to `in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, RICHARD M. WrLLIAMs,of Rockville, in the county of Montgomery,and State of Maryland, have invented a new and useful Improvement in Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the samereference being had to the accompanying drawings, making part 'of this specification, in which- Figure-1 is a rear elevation, and

Figure 2 is a plan view.

This invention consists, f

First, in attaching the linger-bars and platforms to -the frame-Work of the machine, in such a manner that said linger-bars and platforms may rotate about a common centre in a horizontal plane.

Second, iu a device for pulling cut grain upon the platforms, acting like a stationary reel.

Third, in a de'vicefor removing cut grain fromthe platforms in gavels.

In the drawings- A A' are the main driving-wheels, the axle A of which is supported at its ends in brackets a `a,.pro jecting downward from the under side of the circular frame B, the latter having a rim, b, which serves as a trackifor the friction-rollers c to run on, which rollers support the wheel C, running on a spindle at the centre ofthe circular frame B. w

The wheel C has cogs on the lower part of its rim, by means of which it is connected, through suitable gearing, with .the fixed spur-gear of the main drivingwheels.

Upon the same spindle that forms the axis of Athe wheel C are loosely placed the bands or rings, at the inner ends of the bracket-supports c of the fingerbars, the hub running up far enough on the spindle to admit them, the braeketsupports being connected with the spokes of the Wheel C, and resting on them,

` by wooden pins, which break easilyenough to admit ofthe severance of such connection, against the stress of an obstruction met with by the platforms attached to the lower and outer ends of the bracket-supports c, and too powerful to be removed thereby, thus preventing fracture of more'important parts of the machine.

The attachment of the platforms D to the lower and outer. ends of the bracket-supports cis effected by slotted bars d, on the latter, and set-screws.

On the common spindle, above the extensions, is a rigid circular frame, E, the periphery of which is toothed, with which teethengage the cogs of the vertical shaft e e, revolving in boxes in the bracket-supports c, which vertical shafts rotate the crank-wheels c', the latter communicating their reciprocating motion to the sickle-bars.

As the machine advances, the opposite platforms D revolve in a horizontal plane, cutting a swath about equal in width to the distance from the centre of the frame to the outer end of eitlie1 iinger-bar. This arrangement also quite avoids side-draught.

The wheels C and circular frame E should be of sufficient diameter to afford all necessaryleverage to the rotation of the platforms.

' The finger-bars and platforms, not being required to support any ofthe weight of the machine, may be -h, projecting from it, that hooks at its outer end into a loop,'h, in the centre of the cross-barh, which jpins the tops of a pair of vertical rods, it, that pass down through the beam G, through tubes l Z, aiixed to the under side of said beam, and having a rake-head, k, fastened to their lower ends, the teeth of which project down nearly or quite to the level of the platforms. v v

lhe function of the rake is to sweep the cut grain from the platforms D as they come roun under it.

A foot-lever, k, underthe drvers seat, is so connected with the shaft G', that by a gentle pressure of the foot, the rake maybe raised, and the platform be thus allowedto take two or more revolutions before being cleared of its load, and the driver regulate the size of the gavels vat his option, according to-the lightness orheaviness of the grain.

From the frame F, always in the opposite direc- Y tiou.to the rake, projects a-beam, H, carrying aseries of horizontal lingers, l', which move through the grain, condensing it lfor the operation of the sicklebar, when it shall come round, the length of the fingers being so varied as that those above the sicklebar shall always project over the outermost4 teeth of the latter'.

After the grain is cut, the fingers l uphold it till it settles down on the platform, immediately in the Wake of the cutters,

Having thus described my invention,

What I claim as new, and 'desire to secure by Letters Patent, is-

1. ,The platforms D D and, finger-bars, placed op-y posite each other, and arranged so as to rotate, with their sickle-bars,- in a horizontal plane, about a common centre, substantially as and for the-purposes exrake k, arranged to act as described, and with the planed. extent specified.

2. In combination with the revolving platforms RIOHD. M. WILLIAMS. and the finger-bars, the beam H, carrying the graded l series of fingers Z', arranged tooperate in the manner Witnesses: and to the end set forth. NATHAN K. ELLSWORTH,
