UNITED STATES PATENT OFFICE.

\VALLACE R. \VOOD, OF OLIYET, MICHIGAN, ASSIGNOR OF ONE-HALF TO EARL C. COREY, OF SAME PLACE.

BEAN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 596,466, dated December 28, 1897.

Application filed July 2, 1896. Serial No. 597,879. (No model.)

To aZZ whom it may concern:

Be it known that I, \VALLACE R. \VOOD, of the village of Olivet, in the county of Eaton and State of Michigan, have invented a new and useful Improvement in Bean llarvesters, of which the following is a specification.

My invention relates to bean-harvesters; and it consists in the improvements hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a plan view of a bean-harvester embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of the same with the front crosspieee of the frame removed. Fig. i is a detail view of part of the connecting and diseonneeting mechanism, and Fig. 5 a vertical section showing the clutch-spring.

The same letters and figures of reference refer to the same parts in all the views.

AA are the outside and 1313 the inside longitudinal beams of a rectangular frame. 0 is the rear and D the front cross-piece of said frame.

E F are the wheels which carry the frame A 13 C D and the other parts of the machine.

G II are yokes passing over and upon both sides of the beams A A from above to a point below said beams.

I is a shaft or axle having the wheel E keyed upon its outer end, said shaft being adapted to turn in bearings in the lower end of the yoke G.

J is a shaft similar to the shaft I, but located upon the opposite side of the frame A I; C D. The shaft J has the wheel F keyed upon its outer end. Said shaft is adapted to turn in bearings in the lower end of the yoke H.

K K are two steel shoes lying side by side and parallel to each other toward the rear of the machine, but diverging symmetrically from each other at their parts toward the front of the machine. Said shoes rise upward in a curved line toward their rear ends, as shown at a, Fig. 2. Said shoes are rigidly secured at their forward ends to the lower ends of standards I. L. Said standards extend approximately vertically from the forward ends of the shoes K K to a point above the frame A D C D, and are pivoted at b h to the beams B I so as to turn in a plane at right angles to said beams.

M is a coil-spring acting to press the upper ends of the standards I. L apart and consequently to press the shoes K K toward each other.

N is a wheel keyed upon a shaft )1, which shaft is adapted to turn in bearings upon the beams B I and is located vertically above the shoes K K.

I l are arms extending radially from the periphery of the wheel N. The arms I. I extend between the parallel portions of the shoes K K, and said shoes are forced against said arms by the spring M.

Q Q are parts of clutches rigidly secured to the wheels E and F.

R R are sprocket-wheels upon the shafts l J.

r r are parts of clutches rigidly secured to the sprocket-wheels R R. Said sprocketwheels are adapted to turn freely upon the shafts I J, except when clutched to the wheels E F by the intermeshing of the teeth of the clutch parts Q r Q r.

S is a counter-shaft extending transversely across the frame A l C D in front of the wheels E F and adapted to turn in bearings on said frame.

(Z (Z and are sprocket-wheels upon the shaft S.

T is a sprocket-wheel upon the shaft 11. The

sprocket-wheels R R and (Z (Z are connected by sprocket -chains ff, and the sprocket- Wheel 6 is connected to the sprocket-wheel T by a sprocket-chain g.

\V IV are arms rigidly secured to the lower ends of the yokes G II and pivoted to the shaft S.

2 is the seat for the driver.

3 is a shaft extending transversely across the rear end of the frame A 13 C D. l 4 are drums or pulleys on said shaft.

5 5 are ratchet-wheels upon the shaft 23.

6 (3 are pawls adapted to engage the teeth of the ratchet-wheels 5 5.

7 7 are drums or pulleys pivoted in bearings upon the upper ends of the yokes G H.

8 8 are chains secured to the pulleys l 4 at the peripheries of said pulleys, passing thence over the pulleys 7 7, and having their other ends fastened to the machine-frame A 13 O l).

9 is a lever by which the shaft 3 may be turned.

it h are grooved wheels forming part of the sprocket-wheels R R.

i 2' are levers pivoted to the yokes G H and provided with forks y at their lower ends, which forks fit into the grooves of the pulleys h 7L. Said forks and pulleys constitute the well-known shifting-gear by which the clutches Q 0' may be engaged and disengaged.

p p are plates secured to the sides of the beams A A and having their upper ends bent inward.

1O 10 are springs, one of which is shown in Fig. 5, acting to throw the clutch parts Q a Q 0'' into engagement. The upper ends of the levers 'i i are bent inward, and the relative position of said levers i i and the plates p p is such that when the upper ends of said 1evers are in contact with said plates said clutch parts are separated. IVhen said lever is not in contact with said plate, the springs 10 10 cause said clutch parts to engage with each other. (See Fig. 4.)

The revolution of the wheel N causes the arms P P to remove any vines that may have caught between the shoes K K.

Having fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a bean-harvester the combination of the frame, A B, the shoes, K L, said shoes being curved upward and parallel at their rear ends and being adapted to move toward and away from each other, and the spring, M, acting to force said shoes together, substantially as shown and described.

2. In a bean-harvester the combination of the frame, A, B, the shoes, K, L, pivoted to said frame and adapted to swing toward and from each other, the spring, M, acting to force said shoes toward each other, the wheel, N, having arms P, extending between said shoes and means for rotating said wheel substantially as shown and described.

3. In a bean-harvester the frame, A, B, a shaft, S, wheels, E, F, axles, I, J, the shoes, K, L, the wheel N, bearing in said frame and extending between said shoes, sprocketwheels on said axles and said shaft, sprocketchains connecting said sprocket-wheels, the wheel, N, being connected to said shaft by sprocket-gearing, substantially as and for the purpose described.

4. In a bean-harvester the frame, A, B, pivoted to a shaft S, the yokes, G, H, provided with arms, W, \V, said arms being pivoted to said shaft, said frame being secured to said yokes by an adjustable attachment, shoes, K, and L, pivoted to said frame, the wheel, N, pivoted in said frame and extending between said shoes, said wheel being geared to said shaft, wheels, E, F, having axles, I, J, hearing in said yokes, said shaft being geared to c said axles, substantially as shown and described.
