Letters Patent No. 110,772, dated January 3, 1871.

lMPROVEME NT IN CORN-HUSKERS.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern:

Be it known that I-, ABEL Mnnwm, of St. J oseph, in the county of Berrien and State of Michigan, have invented a new and useful Improvement in Corn-Huskers rand I do hereby declare the following to be a full, clear, and exact description thereof, reference being had'to the accompanying drawing forming part of this specification, in which' Figure 1 is a side elevationot' my invention, with a port-ion of the frame broken off, showing the working parts of the machine; and

' Figure 2 is a vertical transverse section of the same. I

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

My invention has for its object a device by which corn may be separated from the husk; and

The nature of my improvement consists in a vertical moving cutter-bar, provided with a device for cutting the husk from the cars, which acts uniformly with the vertical movement of an oscillating cutter for separating the same.

To the lower end of said cutter is pivoted'an automatic tilting lever, communicating with the cuttinglever, whereby the uniform movement is obtained.

In the accompanying 'drawing- A indicates the frame-work of the machine, which may be as shown, or it may be of any suitable form that will receive the moving parts.

B is a cutter-bar, which is so arranged as to move vertically upon guides or wayssecured within a mortise cut through the platform 'of theframe.

The upper end of said bar is bent outward at a right angle with its edge, and is provided-with a cuttor-blade, O. 1 I

Secured to the lower side of the platform is a depending brace, D, to the lower end of which is pivoted an automatic tilting-lever, E, which is joint-ed at one end to the lower end of cutter-bar B.

J (noted to the opposite end of said lever is a vertical bar, 1 the upper end of which is secured within a mortise, (I, cut through said platform, and is fitted in a manner admitting of a free and easy vertical movement.

Said bar is provided with a vertical groove or channel, 6, within which is secured a stripping cuttingtool, G.

The lower end of said tool is secured to the flanges of bar F, by means of pivot, j, passing through the same, and is bent outward at a right angle with its edge, and provided at or near the'outer end with a lug-pin, g, resting against the outer side of spring H,

secured to the lower end of said bar.

Secured to the posts of the frame, below the platform, is a girt, I, upon which is a lug, 71, so arranged as to come in contact with the outward-projectin g end of stripping cutting-tool G, as the same is moved upward by the action of lever E, thus imparting to said tool an oscillating movement.

I provide said c utter-bar B with a slot or mortise, '5, within which is secured a vertical rod, j.

Around said rod is a spiral spring, I, the lower end of which rests upona guide-plate, m, secured to the upper side of the platform.

Attached to said cutter-bar is a pitman, J, extending downward to treadle L, secured to the frame of the'machine.

Secured to the upper side of the platform is a plate, M, which is provided with vertical uprights, not, the inner sides of which are cut away, forming a recess, into which the ear to be husked is placed.

The operation of my invention is as follows:

The ear to be husked being in said recess, power is applied by the foot of the operator to treadle L, which communicates with cutter-bar B by means of pitinan J, imparting to the same a simultaneous downward movement, with an upward movement of stripping cutting-tool G of bar F, by the automatic tilting movement of lever E, thus bringing the lower end of said cutting-tool in contact with lug It, imparting to the same an oscillating movement, by which the ear is separated from the husk as it is disengaged by cutter-blade O.

Spring 1 then rccedesas the foot of the'operator is removed from the treadle, and by which the cutters are adjusted-to receive another car.

Having thus described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the cutter-blade O, the cutting and stripping-tool G, constructed and arranged to operate in the manner shown and for the purpose set forth.

7 2. The combination and arrangement of the cutterbars B and F, cutter-blade 0, cutting and strippingtool G, lever E, lug It, springs H and I, rod J, and

treadle L, substantially as. and for the purpose described.

ABEL MERWIN. Witnesses G. H. Fnos'r, N. H. Snnnnunnn.
