HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 223,356, dated January 6, 1880.

Application filed September 20, 1879.

To all whom it may concern Be it known that we, RICHARD H. JONES and JOHN L. OWENS, of Minneapolis, in the county of Hennepin and State of Minnesota,

have invented a new and useful Improvement in Harvesting Machines, which is fully described in the followin g specification, reference being had to the accompanying, drawings, in which-- Figure 1 represents a plan view of a machine embodying our improvements, the grainplatform being mostly broken away; Fig. 2, a side elevation of the same, partly in section, on the line 00 m, Fig. 1 Fig. 3, a front elevation of the shoe; and Fig. 4, a detail section taken on the line 3 y, Fig. 1.

Our invention relates to that class of machines adapted for use either as a mowing or reaping machine, usually known as combined machines.

The invention consists in special combination of mechanism for tilting or rocking the cutting apparatus.

It also consists in Special devices and com- 2 5 binations of devices, all of which will be hereinafter more fully described, and pointed out definitely in the claims.

I11 its main features the machine may be of any ordinary and wellknown construction,

0 and these parts will only be referred to in this description.

The machine, as shown in the drawings, is rigged as a reaper. There are, of course, the usual supporting and driving wheels A on a 5 main axle, B, on which is mounted a main frame, 0. This frame is formed from a single bar of wrought-iron bent in a rectangular form, the two ends being joined at the inner front corner and projecting slightly forward,

4.0 to provide for the attachment of the pole D,

as shown in Fig. 1 of the drawings.

The frame is set upon its edges, and the inner side bar is bent outward at the front end, to form an arm, 0, projecting laterally in 5 front of the inner drive-wheel. This frame is fastened to two lugs or arms, 0, mounted at their rear ends loosely on the main axle and extending forward, being provided with upright flanges c, to which the sides of the frame O are bolted. The counter-shaft has its bear ings in these arms O, and an angular box, D,

is fitted and fastened to the rear outer corner of the frame, which boX forms the bearings for the crank-shaft.

The shoe E is of ordinary construction, except that it is extended upward at its front end some distance, so as to form a projection, 6, above the shoe proper, in which is a vertical slot, 0.

A bridge, F, adapted to support any ordi- 6o nary combined revolving rake and reel, and the gearing for driving the same, is bolted to the front and rear ends of the shoe.

The finger-beam G is attached to the shoe in the usual manner, and the grain-platform H is fastened to the shoe and finger-beam.

A draft rod or bar, I, is mounted at its forward end in the outer end of the arm 0, being passed through a hole in the arm adapted to receive it. This draft-bar extends rearward, and is passed through the slot in the forward end of the shoe to the rear end of the latter, where it is inserted in a suitable bearing-hole in the rear lug of the shoe, and secured by pins it, arranged, respectively, in front and rear of the lug. The shoe is thus free to turn on the draft-bar, and the joint at the rear end thereof must be sufficiently loose to permit the shoe to vibrate vertically about that point as a center to a limited extent.

A brace-rod, 1, is attached to the forward end of the draft-bar, and extended thence forward and inward to the place to which it is fastened.

The coupling-bar J is connected at one end to the rear end of the draft-bar, just inside of thelug of the shoe, by passing the draft-rod bar through it, the other end being hinged to some part of the main frame in the usual way.

Arock-shaft, K, is mounted in suitable beargo in gs supported on the draft-bar, and is provided at its rear end with a crank-arn1,k. In this instance the bearings of this shaft are in a post, is, fastened to the draft-bar just in front of the shoe, and in one arm of a notched seg- 5 went fastened to the arm 0 and to the upper end of the draft-bar. The crank-arm k is arranged to project laterally from the rock-shaft, and a link, L, is pivoted at its lower end to the outer end of the crank, its upper end being hinged or pivoted to the shoe by means of a pin, 1, or any other suitable device.

A lever, M, is fastened to the forward end of the rock-sh aft, and is provided with a spring catch or latch,m, which engages with a notched segment, N, arranged transversely of the machine, and fastened to the draftbar and arm 0, as stated above.

Now, it is evident that the oscillation of the rock-shaft K will vibrate the crank-arm on its rear end, thereby pulling down or lifting up the link L, and, through its attachment to the shoe, vibrating the latter on itsjoint at the rear end of the draft-bar. This will, of course, tilt the finger-beam, so as to depress the ends of the fingers for the purpose of picking up lodged graiif or g "ass, or elevate them to pass over an obstruction, or for any other purpose, the diiferen t positions of the tin ger-beam being shown in dotted lines in Fig. 2 of the drawings.

The oscillation of the rock-shaft is effected by the lever M, and the finger-beam is locked in any adjustment. desired by means of the springcatch on the lever and thenotched seg ment.

It will be understood, of course, that when the machine is used as a reaper the grain-platform is supported at its outer end by an ordinary grain-wheel, which forms the fulcrum on which the finger-beam and platform vibrate at that end of the machine.

Theinn'erend of the finger-beam is raised and held up at the proper distance for cutting grain by any of the usual devices for this purpose. In the drawings a lifting-lever, O, is shown, which is connected by a chain, 0, with a stiff arm, P, extending outward from the fingerbeam, the lever being provided with the usual devices for securin git in any adjustment. The inner end of the finger-beam is lifted up to the desired height for cutting grain, and held in this position by means of this lever, and then, by tilting the shoe, as above described, the cutting apparatus will be brought to the level position required, and may be tilted in either direction from this position in which it is set, as above described.

The in achine maybe converted from areaper to a mower, and vice versa, in the usualmanner.

In each style of machine the tilting of the finger-beam has been found of great advantage, especially in lodged grass or grain, and the mechanism herein shown and described for effecting this' vibration of the finger-beam is simple, cheap, and efficient, and of course may be applied to machines differently constructed than the machine here shown.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The frame 0, formed of one piece, with the two ends overlapping at the inner front corner and projecting forward for the attachment of the pole, and with a bent end, 0, projecting inward and adapted to support the rod I, all as and for the purpose set forth.

2. The shoe E, provided with a slotted upturned end, 0, in. combination with the rod I and with the rock-shaft K, said shaft being mounted in bearings at both ends, supported upon the draft-rod, and connected to the slotted end 0 by the crank-arm 7t" and the link L, the parts being constructed and operating as set forth.

3. The combination, with the arm ca-nd the draft-bar I, supported upon the end of the said arm, of the segment N, supported at one end upon the draft-bar I and at the other upon the arm a, and carrying the rock-shaft K, the parts being constructed and operating in the machine as and for the purposes set forth.
