" IMPROVEMENT IN cORH-HUSKING- MACHINES.

The Schedule referred to in then Letters Patent and making put ottheume I, ERASTUS H. OARVER,.0f Preble, in .the county of Cortland and. State of New York, have invented an Improved-Gorn-Husking Machine, of which the in their normal position.

Figure II is a plan. Figure III is a sectional side elevation, represent ing the parts in a changed position.

Figure IV is a plan of the bed-plateon which the.

ear to be husked is placed.

Like letters designate like parts in each of the fignres.

A represents a table, supported on legs in any suitable manner, and forming the frame of. the machine.

0 is a bent orreturn-lever, having its fulcrum at the bend, which is formed by casting gudgeons or pivot-pins with the lever, and fitting them .in pillowblocks B B, or other suitable'bearings, secured to the table A, the lever passing through the bed of the table, with the long arm 0 projecting from the under side, while the short arm 0. extends above the table in the same direction as the long arm, so as to move up and down with the latter.

The short arm 0 is armed at its end with sharp flattened teeth, (I d, (preferably three in number,) which project'verticallydownward, as clearly shown'.

E is a bed piate, (preferably of cast-iron,) arranged under the teeth (I, and secured to the table by bolts and screws, in any suitable manner.

This bed-plate is formed with a slot, 0, in line of the teeth .d, which, in their descent, as the lever is operated, pass down through. the same, and. into a corresponding slot formed in the table.

The edge of the slots on one side is raised, forming a'ledge, 0, while the opposite side is formed with a curved depression or recess, e, which extends to the edge of the bed, as shown in Figs. II and IV.

F is a reacting spring, extending upward from the table at the rear end of the lever C, and connecting at its top, by a cord or chain, f, with the short arm thereof, which spring operates to elevate, or to assist in elevating, or in bringing back to its original position, the said short arm after it has been depressed in hnsking an ear, as will presently be explained.

G is a short lever, pivoted near the corner of the table, so-as to vibrate in a vertical slot opposite to and running parallel with that in the bed-plate.

To the front or outcr'end of this lever is hinged a link or slotted stirrup, H in which plays a. pin, 6, pro jecting therein from the long arm of lever 0.

J .is a seat, connected to the under side of the to;- hle by means of a hook, k, which enables the position of the seat to be varied as occasion may require.

The mode of operating my machine, constructed as above described, is as follows:

The operator sits astride of the bench J, facing the machine, with the corn to be husked, arranged on his right, and the machine in the position shown in Fig- I, while the sliort arm and its teeth are elevated above theslotted bed beneath. The operator, with his righthand, takes hold of a stalk just below the ear, and, bringing the same in front, places the ear in the concave recess e of the bed-plate, and draws the ear t ward the righttill the butt of the ear is brought in contact with, and is'arrested by the shoulder e, which brings the point where thefear should be severed.

.from the stalk directly under the teeth (I. The lever is now pressed suddenly downward with the left hand, which causes the. teeth to descend, penetrating the stem, during which movement the pin 2 slides down the slot in the stirrup H till it reaches the lower end thereof, which it does before the lever has completed its movement, when t-he'continu'ed depression of the lever depresses also the outer end of lever G, causing the inner arm, which is preferably serrated, as shown, to rise, and force upward the ear, whilethe teeth and arm are completing theirdownward movement,which operation of the lever G'insures the complete severance of the ear, and, at the same time, loosens it from the husks, which are still attached to the stalk, and held by the arm and teeth 0 (l, the teeth in their de- The advantages'of my improved machine are, its

durability and simplicity of construction, its easy mode of operation, and the'facillty and dispatch with which it accomplishes its work.

Vhat I claimas my invention is- I 1. The arrangement of the bent or return-lever '0 with the table A, reacting spring F, teeth'd, and bed E, substantially as and for the purpose hereinbefore set forth.

2. The-combination of the lever G with the-lever O and bed E, arranged and operating as hereinbefore set fO Ith.

3. The link or slotted stirrup H, pine, and levers O G, arranged and operating as hereinbefore set forth E. H. CARVER.
