CORN-HEADER.

Application filed April 22, 1915.

To all whom it may concern:

Be it known that I, Gnoaen 1V. Kmnow, a citizen of the United States, residing at Yates Center, in the county of \Voodson and State of Kansas, have invented a new and useful Improved Corn-Header, of which the following is a specification.

This invention relates to a device for cutting the heads from Kath corn, sugar cane and the like, and more particularly to a device of this character attached to a board adapted to be substituted for the end gate of av farm wagon or it may be secured to the end gate.

The object of the invention is to so construct a device of this character that it may be easily operated by one man and which will effectively hold the grain in position while being cut.

lVith the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts to be more fully dcscribed and claimed.

In the accompanying drawings: Figure 1 is a rear view of an end gate equipped with this improved cutter; Fig. 2 is a horizontal section taken on the line 22 of Fig. 1; and 3 is a transverse section taken on the line of Fig. 1.

in the embodiment illustrated the device constitt this invention is shown applied to an end l 1 to 1 of ordinary construction aving the usual transverse cleats 2 spaced the ends thereof to assist in retaining operative position, but obviously it a av be secured to any suitable support.

This improved cutting device comprises a grain retaining or rest bar 3 preferably constructed of steel which is secured to the oute face of the gate 1 at the upper edge thereof and provided with large teeth i which project above said gate edge and performs the double function of a grain rest and as one member of a knife guide. A bar 5 arranged parallel with the bar 3 forms the other knife uide and is secured to the gate 1 by bolts 6 and 7 at its opposite ends. On the bolts 0 and 7 are arranged spacing elements 8 in the form of washers to hold said bars spaced a sufficient distance to permit the knife 10 to be described to enter between them. The bolt 6 is arranged Specification of Letters Patent.

in the path of the free end of the knife to form a stop for limiting the downward or closing movement of the knife, the knife having a notch 10 at its free end for engaging said bolt.

The knife 10 is fixed at one end to one end of a lever 11 and disposed at an acute angle thereto as shown in Fig. 1 with its cutting edge 9 arranged toward the lever. The portion of this lever 11 to which the knife is secured is normally arranged parallel with and below the bar 5 and is designed to engage the lower edge of said bar 5 for limiting the opening movement of the knife. The teeth l on bar 8 are inclined toward the fulcrum of knife 10 so that when the knife is forced down into 'itting engagement with the grain, the latwill be held against slipping.

The bolt 7 which connects one end of the bars 8 and 5 with the ate 1 passes also through the inner end of knife 10 adjacent its connection with lever 11, and forms a fulcrum therefor and for the lever 11, said blade having an opening in which the spacer 8 on bolt 7 fits and forms a wear sleeve or bearing for the blade. The free or front end of the lever 11 is offset laterally outward to position it away from the gate 1 when the device is applied. A coiled spring 12 is secured at one end to the rear end of lever 11 at one side of its fulcrum and at its other end to a bracket 13 secured to the gate 1 in a plane below said lever, and exerts its tension to raise the knife and hold it in open position as shown in Fig. 1.

A knife closing device is shown in the form of a stirrup 13 having a connecting rod 14 extending upwardly therefrom and provided at its free end with a laterally ex tending eye 15. The stirrup l3 and its connector 1d are preferably made from a single rod bent to form the stirrup, one end of said rod having an eye 16 through which the rod 14 passes. Another rod 17 depends from the offset end of lever 11 opposite to that to which the spring is attached, and extends through the eye 15 of the rod 1-1: and has a laterally extending eye 18 at its free end which is slidably engaged with said rod ll, said rod passing through said eye. A clamp 19 engages the two rods 14 and 17 and is held in engagement therewith by a set screw or bolt 20. It will thus be seen that the connection between the lever and the stirrup may be adjusted to vary the relative positions of said members at the will of the operator.

In the use of this device, the parts being as shown in Fig. 1, a bundle of grain is placed across the toothed bar 3 below the knife 10 and is held against slipping by the teeth 4 of said bar. The operator then depresses the knife 10 by placing his foot in the stirrup 13' and exerting downward pressure thereon, whereby the knife is closed against the tension of its spring and severs the heads from the stalks, the former droping into the wagon body and the latter outside. VVhen pressure is removed from the Eoplesof this patent may be obtained for five cents each. by addressing the stirrup the spring 12 returns the knife to normal open position.

I claim:

A heading device comprising a bar with means at each end for spacing it from a suitable support. a lever having an ofi-set portion, a cutting blade rigidly attached at an angle to or near one end of said lever and pivoted on one of the spacing means of said bar, and operating means for said lever, said off-set portien of the lever being out of the plane 01" the said bar.
