TRAVELING TH RASHER.

SPECIFICATION forming part of Letters Patent No. 389,884, dated September 2 1888.

Application filed July 26, 1887. Serial No. 245.336.

- clare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appentains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

Our invention relates to improvements in traveling thrashers; and it consists in the combination and arrangement of devices, as will be more fully hereinafter set forth, and particularly pointed out in the claim.

Figure 1 is a longitudinal sectional view of a machine embodying our improvements, the same being taken in the plane indicated by the linear of Fig. 2, with a portion of the frame broken away. Fig. 2 is a plan view, the beam 1) being partly broken away. Fig. 3 is a section in detail, showing the front bracketbearing for the cranked brake-shaft. Fig. 4- is an enlarged detail showing the hand-lever \V and certain parts immediately connected to it.

The frame of the machine upon which the operating devices are supported consists of two main longitudinal beams, A B, arranged parallel to each other and extending the entire length of the machine. To the rear parts of these beams are rigidly secured crossbeams C and E. To the front parts of the said beams A B are also rigidly secured cross-beams F and G, and to the outer ends of the beams O and E are rigidly secured longitudinal beams A B. The beams G and E are bolted to the beams A and B, which latter are supported at their front ends by a guide-wheel, N, and its frame, to which the drafttongue is attached.

Between the beams Aand A is a right-hand transporting-wheel,-N, the short axle of which turns in journal-boxes secured to said beams A and A. Between the beams B and B is the left-hand driving and main carrying wheel M, keyed on an axle which is journaled in boxes on said beams B and B.

The frame-work and wheels above described (No model.)

are adapted to receive and sustain thrashing and separating devices.

P designates a platform,which is secured to the beams B B at the side thereof and in the angle formed thereby.

The frame of the guide-wheel N consists of longitudinal bars H and I, upon which the journal-boxes of the axle of said wheel are secured, and also of the cross-bars J which frame may be pivoted or otherwise suit-ably attached to the front of the beams A B between the cross-beams F and G.

Land L are eyes attached to the ends of the bar J, to permit the draft-tongue to be connected thereto.

K is the seat-standards, which are rigidly secured to the beams A and B, and which extend forward and upward, having the drivers seat j and foot-board i secured to their upper ends.

Having thus given a general description of a carriage which is adapted to support thrashing and separating devices, we will now describe the parts which relate to our improved brake forthe driving and transporting wheel M.

It R designate two brake-straps, which are connected by suitable hinges, a, to a strong cross-bar, R,'seeured to the beams B B, immediately behind the wheel M. These brake straps extend forward over the rim of the wheel M, and are flexibly attached to a double crank-shaft, S, having end hearings in the beams B B in front of the wheel M, and provided with a central bracket-bearing, S, secured to cross-beams D and E.

To the outer end of the shaft S is secured a hand-levenW', provided with a detent adapted to engage with a toothed quadrant, Y. On the inner part of the shaft S is secured an arm, (I, to which a rod, e, is attached,whieh extends forward and is attached to a lever, f, pivoted to the beam B. This lever f is also attached by a rod, g, to a hand-lever, h, which is located in close relation to the driver on the seat J, and pivoted to one side of the foot-board i. By means of a suitable detent on hand-lever hand a toothed sector, 1, this lever can be looked forward when the brakes are applied.

The operation is as follows: To ordinarily stop the team, the driver makes use of the hand-lever h; but in the event of more power being required the auxiliary lever \V is used by a person located on the platform P, the brake-straps R It being, by means of either one or both levers, forcibly pressed upon the wheel M. YVhen lever W is disengaged from the quadrant Y, it may be held by a catch, XV, secured to the end of the bar D.

In practice we shall employ a turnbuckle, T, on the wire, attached to the forward parts of the beams B, for the purpose of securing greater rigidity-from the strain due to the application of the brake straps R It to the driving-wheel M.

Having described our invention, what we claim is- The combinatiomwith the main driving and transporting wheel M, of the brakestraps R R, the rear bar, R, to which these straps are hinged, a cranked shaft, S, having the front ends of the said straps attached to it, the bracket S, supporting said shaft, an arm secured to the said crank-shaft, the lever f, pivoted to the main frame, the rod 6, connecting said arm and lever, a hand-lever, It, provided with a detent and sector, and the rod y, connecting the leversf and 7t, substantially as described.

In testimony whereof we ELffiX our signatures in presence of two witnesses.
