IMPROVEMENT IN HAY-GATHERERS AND SHOCKERS.

The Schedule referred to in these Lettere Pat-ent and making part ox :ne same To all whom yit may concern Beit known that I, CLARK M. TERRELL, of Oskaloosa," in the county of Mahaska and State of Iowa,

l have invented certain Improvements in Combined Hay-- Gatherer, Shocker, and ledder.; and I' do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a sideelevation of my improved machine, showing the guiding-wheel, one of the drivingwheels, the gearing for driving the rake cylinder, and the frame-work.

- Figure 2 is a plan or top view of thevv parts above enumerated, and of the rake-cylinder.

Figure 3 is a sectional elevation of the gathering or rake-cylinder. l

Figure 4 is a sectional end elevation of so much of the machine as is necessary to the devices for raising and lowering the rake-cylinder.

Figure 5 is an elevation of one of the cylinder-heads, showing its inner side, which is constructed with a cam-shaped groove, wherein the ends of two rods are 'made to move by the revolution of the rake-cylinder for the purpose of reti-acting, at the proper point, the rake-teeth.

Corresponding letters refer to in the several figures.

My invention relates to improvements` on a combined hay-gatherer, shocker, and tedder, for which Letters Patent of the United States were granted to me on the 17th of September, 1867.

Such improvements consist- First, in the combination and arrangement of the cylinder-heads, retracting-rods, and rake-teeth.

Second, in the combination with the rake-cylinder of mechanism for adjusting the same vertically.

Third, in constructing the platform upon which the out grass is delivered by the rake-cylinder with a hinged flap, infront, so that it can accommodate itself to various positions of such cylinder.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, in the drawings, lepresents the truck ofthe machine, which is mounted upon two driving-wheels, B and a swiveling guide-wheel, B', in front.

The driving-wheels are placed loosely upon the axle corresponding parts C, having pawls b pivoted on the inner sides of their hubs, which, as the machine is drawn forward, engage with ratchet-wheels C', fastened on the axle, thereby turning the same. In backing the pawls will slip over into and driving a pinion, D', which latter is secured upon the elongated outer end ofthe rake-cylinder shaft. Thus the latter is revolved in a direction reverse to that in which the driving-wheels move in the forward motion of the machine.

E represents the rake-cylinder, which is pivoted to the axle C by means of'two arms or bars formed upon the outer faces of its'heads, and extending the proper distance to the rear, the position of the cylinder being in front ofthe axle C. v

The cylinder has secured in it, one near each end. disks E, which are centrally perforated to receive and be secured upon the shaft E2. This shaft has its bearings in boxes formed in the hars of the lcylinder-heads, projecting some distance through one of 'them tzi receive the pinion D'. The periphery of the cylinder is provided with two longitudinal series of slots opposite each other, through which the rake-teeth are projected.

FF represent two rake-heads, extending from end to end of the cylinder, along opposite sides of its wall, and secured in the disks El.

Upon each one are pivoted teeth Fl, having substantially the forms shown in figs. 3 and 5, and corresponding in number and position with the slots in the cylinder, through which, in the revolutions of the same, they are alternately projected by their own gravity, and again retracted by means of two rods F2, which are also pivoted by their arms f to the rake-heads.

These two rodsextend through the cylinder, one within the curvature of each series of rake-teeth, and project at each end into cam grooves in the cylinderheads.

G G represent two disks or heads which coverthe ends of the rake-cylinder. Bars Gr1 are formed upon them,

running diametricall y across their outer faces, and, ex-

tendingbeyond them to the rear the proper distance, are pivoted to the axle, for which purpose they have seats formed in them near their outer ends, so thatthey can receive such axle and beheld thereto by means of caps in the usual manner. Seats can also be formed in these bars in the center of the heads to receive the cylinder-shaft, which is retained therein by caps se- Y cured to the bars, as shown.

The inner surface of the cylinder-.heads is constructed with an eccentric cam-groove, G2 into which the ends of the rods F2 project. The position and formation of these cam-grooves, and' the arrangement of the rods F2 therein, is such that in the revolutions of the cylinder, its heads with the cam-grooves, of co'urse being stationary, one of these rods shall be gradually forced toward the center of the cylinder as the rake-teeth upon which it is to operate rise above the ground, entirely retracting such teeth into the cylinder by the time their outer ends are in a vertical line with the axila-aud thus holding them until they have passed mit-ting the rake-teeth upon which it operates, and

`which are by this time below the platform, to again project through theslots in the cylinder, which they' will do by their gravity alone.

I H represents a rock-shaft placed in bearing on top of the machine, extending entirely across the same. Its ends are cranked in a horizontal direction, and connected by means of two connecting-rods H to eyebolts ha, which are secured in the bars G1 of the cylinder-herds, serving at the same time to secure oneend of the caps covering the cylinder-shaft.

The rack-shaft H is provided with ahand-lever h1, secured upon it near the drivers seat, by which it can be turned and the rake-cylinder raised or lowered.

A hook, 71.2, fastened on the frame may. be placed over it when it is desired to hold the cylinder in an elevated position.

'lhe connecting-rods pass through slots in the side beams of the truck, and they are on this part provided with screw-threads, and nuts H2 put on them, imping- 'fing upon the upper surface of the beams. By changing the position of these nuts the rake-cylinder can be stationed at any desired elevation.

I I represent a series of slats or ngei's, which are y secured to a cross-barof the truck ofthe machine, in front lof the rake-cylinder, overhanging the same, as shown,rtheir office being to prevent the cut grass which has been elevated by the rakes to roll back'.

K represents the platform upon which the cut grass is delivered by the rake-cylinder. Its front end is provided with a hinged flap, K', resting upon the cylinder, and rising and falling with the same. This platform is to he so arranged on the truck that it can be turned up or entirely removed when the machine is to be used as a tedder.

The front end of the flap consists in a piece of sheet metal, so that it can lay close on the cylinder, and thus prevent the hay from becoming choked at this point.

L represents the shocker platform, which is to be constructed substantially as shown in the drawings. It is pivoted at its front end to the truck, and its rear end, i'om which ,the teeth project, is hung by chains l to eyeboltsL', which pass through and are guided in the `side beams 'of the truck, and are actuated by springs L2 in the manner set forth in my said former Letters Patent. When traveling with the machine from one field to another the shocker platform is detached from the eye-bolts L, and turned up tothe position shown in fig. 1, in which position it is held by attaining-its chains to hooks La on the sides of the truc M M are two metallic bands, which serve to separate the hay which is being raised by the rake-cylinder from that remaining on the ground, and t0 Drevent the hay from clogging the gearing. V

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

1. The arrangement of the grooved cylinder-heads G, the pivoted rake-teeth F1, and retracting-rods F, substantially as and for the purpose set forth.

2. The arrangement of the rake-cylinder E, connecting-rods H, nuts Iii, and cranked rock-shaft H, as a consequence of which the 'position of such cylinder vertically can be determined, and it be allowed to rise above such determined point in case it meets with any obstruction which makes such movement neces Sary. i

3. The combination of the platform K and ilap K with the vertically-adjustable rake-cylinder E, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

CLARK M. TERRELL.
