of Nebraska, have invented certain new and useful Improvements in Broom-Corn Harvesters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to broom-corn harvesters, and particularly to those in which the stems of the heads or brushes are out to a proper or desired length before being discharged from the machine.

A further object is to construct a machine of the character described that will be comparatively simple in construction, durable in use, efficient, and well adapted to the purpose for which it is designed.

\Vith the above and other objects in view, which will readily appear as the nature of the invention is better understood, said invention consists in certain novel features of construction and combination and arrangement of parts, which will be hereinafter fully described aud claimed, and illustrated in the accompanying drawings, in which Figure 1 is a view of one side of the machine. Fig. 2 is a view of the opposite, side thereof. Fig. 3 is a top plan view. Fig. 4is a front end elevation. Fig. 5 is a transverse vertical section through the straightening rolls and the delivery-apron on line 5 5 of Fig. 1. Fig. 6 is a longitudinal vertical section taken through the cutter-bar, reel, and conveyer and straightening-rolls, as indicated by dotted line 6 6 of Fig. 3.

The forward end of the shaft 65 is bent at right angles to itself to form a crank 66, to theinner end of which is connected one end of a chain 67, which passes under a guide-pulley and is connected at its free end with an operatinglever 68, by which the fork 64 may be raised and lowered to discharge the heads at intervals or as desired.

69 denotes the drivers seat, mounted upon the frame 1, and 70 denotes a bar to which the tongue draft devices (not shown) are attached. The upper end of said bar is connected to the end of a lever pivoted to the standard 10 and having an adjustable pawland-rack connection with the said standard, by means of which the draft of the machine may be raised or lowered. I

In operation the machine is intended to be driven through a field of standing corn, the diverging arms 14 being adapted to gather in a row of stalks similar to the ordinary cornharvesting machines and to conduct them to the cutting apparatus, where the heads are severed from the stalks, the reel also aiding in knocking the heads back against the knives. After the heads are cut off they fall packers, and spring-fingers 26 and straightened out and forced upon the platform 30, with their ends projecting forwardly and in position to be trimmed off by the cutting- Wheel to the proper length, the heads being forced along the platform by means of the endless slotted belt 32 and discharged upon the delivery-fork, from which they are dumped at the will of the driver.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation, and advantages of my improved broom-corn harvester will be readily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for harvesting broom-corn, the combination of a main wheeled frame, of an auxiliary frame carried by said main frame, gathering and cutting mechanism carried at the forward end of said auxiliary frame for cutting the heads from the standing corn, straightening-rolls, an endless conveyer for conveying the gathered heads from the gathering mechanism to the straightening-rolls, spring-fingers for aiding in straightening said heads, packing-blades for pushing said heads across the rolls and onto a table or platform, an endless conveyer arranged above said platform to convey the heads across said platform, a cutting-wheel arranged to trim off the stems of said heads, gearing for operating the several parts, and a delivery-fork for discharging said trim med heads, substantially as described.
