STALK-CUTTER.
Specification of Letters Patent.
Patented Oct. 31, 1805.
Application filed February 7. 1905. Serial No! 244,656.
To all whom it may concern:
Be it known that I, FRANK A. LEE, a citizen of the United States, residing at Bryan, in the county of Brazos and State of Texas,
have invented certain new and useful Imrovements in Stalk-Cutters, of which the following is a specification. \.1This invention relates to improvements in harvesters, and particularly to that class of machines embodying cutting apparatus for severing stalks.
The invention resides particularly in the provision of novel mechanism for adjusting the cutting devices by which the stalks are r5 severed in connection with the general arrangement and structure of adjacent parts of the machine.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.
While the invention may be adapted to 2 5 different formsand constructions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings,
in which Figure 1 is a perspective view of a machine embodying the invention. Fig. 2 is a view showing the general structure of the machine in front elevation. Fig. 3 is a bottom plan 3 5 view. Fig. 4 is a sectional view taken about on the line X X of Fig. 2 looking downward. Fig. 5 is a detail perspective view, partially broken away, showing more clearly the operative devices for adjusting the position of the 4 cutters.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
In carrying out the invention a suitable supporting-frame 1 is provided, said frame embodying transverse and longitudinal bars.
From the frame 1 extends a tongue 2, to which the draft is applied, and said frame is 5 mounted upon an axle 3 of arched formation, such as is commonly employed in machines of the type to which the invention relates. The tongue 2 is provided near its rear end with a draft-bar 4, to which the swingletrees are attached in the customary manner. The
ioo
In order to hold the cutter-frame 11 at an ascertained adjustment, engaging dogs 20 are provided, the latter being suitably mounted upon the bars 9 at the ends thereof and adapted to engage the rack-teeth 13 of the members 10, so as to prevent lowering of the latter after the cutters 12 have been raised by actuation of the shafts 14.
Extending downwardly from the draftbar 4 are spaced guide-fingers 21, which curve toward each other at the lower extremities, and these guide members serve to direct the stalks into the space between the cutters 12 as the machine advances over the field in actual operation thereof.
The cutter-frame 11 is braced from lateral stress by means of vertically-arranged braces 22, connected at the lower ends thereof with the cutter-frame, the upper portions of the braces 22 passing through plates 23, attached to the sides of the frame 1, the braces being freely movable through the plates 23 as the cutter-frame is adjusted by raising and low ering the same.
zg' fit the sides of the cutter-frame 11 and eX- are attached to the members 10 and the braces 22 by suitable securing members 25,
and these plates form a sort of hopper or hood above the cutter-frame. The members 24 of course are elevated and lowered by the adjusting devices, which accomplish the same result in varying the positions of the cutters 12.
Having thus described the invention, what is claimed as new is V In a harvester, the combination of a supporting-frame, supporting-members mounted upon said frame and provided at their upper portions with a plurality of rack-teeth, a cutter-frame carried by the lower ends of the supporting members aforesaid, cutters mounted upon the cutter-fra1ne, shafts mounted upon the supporting-frame, pinions carried by said shafts and in mesh with the rack-teeth of the su porting members for cooperation with the latter to effect adjustment of the cutters, dogs disposed above the pinions and arranged to engage the rack-teeth aforesaid, and curved plates carried by the supporting members at opposite sides of the cutting-frame.
In testimony whereof I afIiX my signature in presence of two witnesses.
