ASSIGNORS 'I O O. AULTMAN 85 OO., OF CANTON, OHIO.

IMPROVEMENT IN GRAIN AND GRASS HARVESTERS.

Specification forming part of Letters Patent No. 10,038, dated September 20, 1853; Reissue No. 726, dated I May 17, 1859.

.To all 'whom it may concern DIvIsIoN F.

, for the driver of the team by which the Ina- Beit known that PHILO SYLLA, of Elgin, in chine is drawn,-

the county ot`Kane and State of Illinois,'and AUGUSTUS ADAMs,formerly of the same place,

, but now residing at Sandwich, in the county ofDe Kalb, in said State, invented certain new and useful Improvements in Machines for Harvesting Grain, Mowing Grass, Src., of which the following is a full, clear, and exact description, reference being had to the annexed drawings, which make part of this specification, and in which- Figure 1 is a view in perspective of a machine, showing one mode of applying said improvements, the finger-beam being raised from the ground to adapt the machine for reaping. Fig. 2 repr-esents a plan of a portion ofthe under side of the machine, to exhibit more fully 'the flexible connection ot' the tin ger-beamwth the main frame. Fig. 3 represents a plan of the machine, the linger-beam resting on the ground to adapt the machine for mowing. Fig. 4c represents a vertical transverse section of themachine at the line l 1 of Fig. 3. Fig. 5

represents a vertical longitudinal section of I the-same at the line 2 2 of Fig. 3; and Fig. 6 represents a plan of the cutting apparatus, the finger-beam, and the coupling-arm for connecting the finger-beam to the main frame. Fig. 7 is a vertical section at the line 3 3 of Fig. 6, showing the provision for allowing play in the joint between the finger-beam I2 and the yielding bar K.

That side of the machine which runs next the standing grain we call the left7 side, and the other, at which the horses are placed, we call the right7 side.

The accompanying drawings represent a machine having a frame large enough to support, in addition to the cutting apparatus and machinery required for mowing, a removable platform placed behind the cutter, (such as is common in ordinary machines adapted to rea-ping and mowing,) an elevated table behind the platform to bind the grain upon, stands for a raker and binders, a dumping-tray to carry the sheaves until a sufficient quantity for a shock has accumulated, and then to dump them in a heap upon the ground, and a stand or place Whenever It may be expedient to use one or more of the several parts or branches of said improvements separate from the rest, such part or parts might be used in connection with frames and gearing more convenient than those herein described, which are proportioned and arranged with reference to the use of the whole of the parts together; and it-is obvious that several parts of the said improvements are applicable to various other reaping or mowing machines in use. One mode of applying each of these improvements to practical use is shown in this machine. It is therefore unnecessary to specify the manner of applying the parts, respectively, to other machines, as the ordinary skill of a constructer is sufcient for that purpose.

`When the tinger-beam ot' a harvesting-machine is so connected to the main frame that it is free to riseand fall at either end, and, while'moving over uneven ground, free to accommodate itself to inequalities in the surface of such ground, and has its upward and paratus into the bank, thereby producing a dangerous strain and often stopping the Inachine. 'lo obviate this difculty in crossing ditches and furrows without interfering with the freedom of the nger-beam to conform to the general irregularities ot' the surface of the ground, which in land adapted to being mowedv by a machine chietly consists of gentle undulations, the saidinven tors have combined with the mechanism by means ot' which the lingerbeam isv connected to the main frame and allowed to rise and fall a stop so arranged that While it will not interfere with the rising of the beam it will arrest its descent at the end next the main frame after having fallen a little below the level of the top of the ditch or furrow, andl will carry the beam, suspended to the main frame, over -the ditch until it strikes the machine to cross them.

' the surface of the ground on the opposite side,

thus preventing the diiculties that would arise from the beam dropping bodily into the ditches and furrows when it is necessary for This stop is the improvement which it is designed to secure under this patent. 1

As the several parts of the machine are fully described in other patents granted to us at the same time and bearing the same date as this, We deem itnecessary to describe particularly in this patent such parts only as relate more irn- Inediately to the improvement claimed herein. The right end of the finger-beam I2 in this machine is connected to the frame by means of a strong link or coupling-arm, J, hinged at its left end to the right end'of the finger-beam and at its right end to a cross-beam, E', of the main frame.

The progressive motion of the frame on its Wheels carries forward the coupling'arm, andthat in its turn carries forward the finger-beam and cutter, and as the lcoupling-arm is rigid laterally only, and its left end (to which the finger-beam is connected) free to rise and fall, the finger-beam necessarily rests on the surface of the ground when not adj-usted fonreaping. Therefore in passing over undulating ground the finger-beam Will rise or fall ateither or both ends and sway up and down Within certain limits, as may be required, Vto conform to the surface of the ground;

The coupling-arm and finger-beam are supported by a yielding bar or brace, K, extending from the junction of the left end of the coupling-arm with the right end of the finger- `beam backward,and connected by a hinge,K2,

to the cross-bar B3 of the frame. Since, however, this machine is designed for reaping as' Well as mowing, and must therefore be capable of carrying a platform whenever it is required to be used as a reaper, and must likewise be capable of carrying the finger-beam at the same time at a height of several inches above the ground, a second yielding bar, K, is provided to support theleft end of the finger-beam, to which it is attached at its forward end, and is hinged to the side rail, A2, of the frame on a pivot, K4.

It' the machine should be crossing a ditch,

with the finger-beam parallel or but little inclined to the same, from the readiness with which the beam conforms itself tothe surface ofthe ground it would of course drop bodily into the ditch, and the cutting apparatus abutting against the bank would cause a sudden shock, that would strain, ifit did not break, the machine. To prevent such difficulties astop is provided, which operates to limit the descent ofthe right end of the linger-beam belowr the level of the track which the driving- Wheel would make when crossing the ditch, but will notrestrict its rising. In thsinstance the stop is made in the form ot' a hook,T, and is attached rigidly in an upright position to the yielding bar K, so as to overhang one ofthe beams A4 of the gearing-frame. rlhe lip tof this hook is generally carried at some distance above the frame; but when the cuttingapparatus is passing across a ditch or other like depression of the ground, then thelip of the hookrests upon the frame, suspending the right end of the finger-beam, With the coupling-arm J and bar K attached, and carrying them over the ditch. When the right end ofthe finger-beam is thus carried over a depression the left end in geueral passes through Without danger, rendering it inexpedient to arrange a stop at that end also.

What is claimed under this patent as the invention of the said SYLLA and ADAMS isf The combination of a stopwith the mechanism for connecting the finger-beam with the main frame and allowing it to rise and fall, substantially as herein set forth.

In testimony whereof We have hereunto subscribed our names.
