IMPROVEMENT IN CQRN-HARVESTERS.

Specification forming part of Letters Patent No. 14,730, dated April 22, 1856; Reissue No. 6l S, dated 4 November 2, 1858.

To all whom Vit may concern.:

Be it known that we, ll.. U. MAUCK and W. T. MCGAHEY, the former of Conrads Store, and the latter of lllcGaheysville, Rockingham county, Virginia, have invented a new and useful Improvement in Corn-Harvesters; and we do hereby declare that the following is a full, clear, and exact description ot` the construction and oper ation of the saine, reference being had to the annexed drawings, forming part of this speciiication, in which- Figure lis atop view ofthe harvester. Fig. 2 is a vertical section on line a: x. Fig. 3 is a front view.

part of the harvester.

The object of our invention is the gathering of Indian corn on the stalk for depositing in shocks, and is designed to cut the stalk, deliver it across the machine, deposit it in the receiver, and eut the stump near the surface of the ground.

The invention consists in constructing in front of the machine a double series of cutters, operated from the rotation of one of the wheels, for the purpose of cutting the stalk and re moving the stumps, and in constructing above the upper cutters frames oscillated by the vibration ot' said cutters for throwing the cut stalk across the machine upon an inclined guide leading to the body of the machine, where radial arms of the main shaft seize the stalk and convey it to the rear of the body, the details of construction and operation being as follows'.

In the drawings, A is the body of the machine, supported so as to run close to the surface of the ground upon the main axle B, upon which are the wheels G C'.

ln front of the machine are the two series of cutters a and b, operated simultaneously from the rotation of the wheels O by the alternate action of the pins c upon the opposite inclined blades, cl d', connected with the cutterbars, or by any of the usual methods of producin g the reciprocation of the cutter-bar from the rotation ot' the driving-wheel; The upper cutters, a, which are the ordinary triangular cutters, vibrate beneath and in contact with the stalk-receivers f, whose edges e are sharpened, so that a shear cut is made between them and cutter a. We do not design, however, to restrict ourselves to this construction of cutter. The lower cutters, b, are also triangular, and by their reciprocation sever the stumps with which they come in contact.

Hinged upon the upper edges of the projecting side pieces, g, are the frames h It', connected by the rod t', and oscillated laterally by reason of connection l with bar in of cutters. Ex tending obliquely forward from the front of the body is the guide u', which submits the stalk to the arms oi' the main shaft B. The front of the body has a curved interior, o, so that arms p of the shaft will carry the stalk under the guides g, whence it is forced to the rear of the body, as will be set forth. The l wheel C' is placed loosely upon the shaft, and has a ratchet-and-pawl connection, t', so that in backing the wheel G will turn loosely, and not act on the shaft.

The operation of the harvester is as follows: It is driven forward, so that one of the stalkreceivers f will embrace each stalk ot' a row as it comes in contact with the said stalks, each stalk passing to the narrow portion of the said receiver and being severed by the cutter a, working under the receiver in operation. As the stalk is cut the vibrating frame h (or h', depending on the cutter in operation) throws it upon the inclined guide u across the machine, whence it falls within the action of the arms p, which convey it to the rear of the body under guides q. Simultaneously with the cutting of the stalks by the cutter a the cutters b sever the stumps from the ground and permit the passage of the machine. Then the stalks of one row are all gathered the machine is turned and driven across the field in the opposite direction, bringing the other receiver j and cutter a in action to gather the next row of corn. In this manner the operation is contin ned, each side of the machine being brought into operation alternately,the loads being de posited for shocking at suitable intervals.

What we claim Vas new and of our own invention, and desire to secure by Letters Patsigned ourl names before two subscribing witent, ismesses.
