HENRY M. PARIS, OF KINGSTON, TEXAS.

CGTTON-CHOPPER.

To all whom it may concern:

Be it known that I, HENRY M. PARIS, citizen of the United States, residing at Kingston, in the county of Hunt and State of Texas, have invented certain new and useful Improvements in Cotton-Choppers, of which the following is a specification.

My invention relates to new and useful nnprovements in cotton choppers.

The object of the invention is to provide a machine having a frame on which cotton chopping mechanism may be arranged and particularly to arrange mechanism whereby the frame may be adjusted with relation to the axle of the machine, the adjustng mechanism including springs for assisting in raising the frame.

Finally the object of my invention is to provide a device of the character described which will be simple, strong, durable, eflicient and comparatively inexpensive to construct.

With these and other objects in View my invention has relation to certain novel features of construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawings, wherein:

Figure 1. is a side elevation of my device, Fig. 2. is a plan view of the same, Fig. 3. 18 a side elevation of one of the levers used on my device, and Fig. 4. is an end elevation of the same.

In the drawing the numeral 1 designates an arched axle which is supported between the ground wheels 2. A frame 3 fixed to slide up and down on the axle 1 carries near its forward end hoes 4 adapted to chop the cotton and means for operating the hoes which consists of a transverse shaft 5 carrying a sprocket 6 at one end a bevel gear 7 near its center; the sprocket 6 has connection with a sprocket 8 carried by the ground wheel 2 through a chain 9 while the bevel gear 7 meshes with a bevel pinion 10 mounted on a longitudinal shaft 11 which is supported in bearings 12 and 14.

A large sprocket 15 is mounted on the end of the shaft 11 transmitting power through a chain 17 and sprocket 18 to a crank shaft 16 to which the hoes 4: are attached. The upper ends of the hoe handles are pivotally connected to levers 19 and 20 loosely mounted on a shaft 21 directly under the shaft 11.

To raise the frame 3 with relation to the Specification of Letters Patent.

Application filed October 4, 1909.

Serial No. 520,922.

axle 1, I have provided a shaft 22 supported from the axle 1 by bearings 23 and 24 while racks 25 are carried by the frame 1 arranged to mesh with toothed segments 26 and 27 which in turn are fixed to the shaft 22.

A lever 28 having a foot 29 rigidly fixed on the end of the shaft 22 is used to revolve the same and to swing the segments to raise or lower the frame. A plunger lever 30 pivoted to the lever 28 near its center carries a lug 31 near its lower end which normally extends through the lever 28 and engages in apertures 32 in a suitable rack carried by the frame as best shown in Figs. 3 and 1.

A spring 34E assists in raising the frame while rear wheels 35 keep the same from rocking or binding. An idler 3G hingedly connected to the frame is held against the chain 9 by a spring 37 so as to keep the same adjusted when the frame is moved.

Cultivator beams 38 hitched to the axle 1 extending beneath the frame, are provided with suitable cultivator feet 39 and blades 40 as well as a means for raising and lower ing the same with relation to the frame said means comprising a shaft 41 mounted on the frame, arms 4-2 made rigid thereto and links 43 which connect with the beams 38.

A lever 44 fixed 011 the shaft 41 and arranged to rock the same is within easy reach of the operator who should occupy the seat 45 carried on the frame. It is obvious that the operator can raise or lower the gangs at will or may look them in a set position by allowing a plunger 4:7 to engage with the teeth carried on a rack 48. This plunger 47 is normally held out of engagement by a. ring 49 secured to the top of the leverfta which is slipped over the plunger operating means.

The distance between the cultivator beams 38 can be regulated by a lever 50 fixed on a shaft 51 which is mounted in the frame 3. On the shaft 51 an arm 52 extends forward and has connection with a chain the ends of which after passing over pulleys 5 1 cross and are fastened to the beams 38. The beams 38 are normally held apart by springs 55 but may be drawn together by pressure on the lever 50 which will rock the shaft 51 and the arm thus tightening the chains The draft attachment 56 is positioned so as to work independently of the frame 3 and is supported by brace rods 57, 58 and 59 which have connection with the axle 2.

Thus the center of draft attachment remains the same while the frame may be raised or lowered to meet varied conditions.

For interrupting the transmission of motion to hoes at and shaft 11, a clutch 57 is mounted on the shaft 5 and connected with the same so as to slide into engagement with a clutch hub 6 on the sprocket 6.

WVhat I claim is:

1. In an agricultural implement, the combination with a frame supported on an arched axle, of racks fixed to the frame at its junction With the arched axle, a lever supported from the axle having connection with segmental gears adapted to engage with the racks to bodily raise the frame with relation to the axle, and springs fastened on the axle having connection with the frame and arranged to assist in raising the frame.

2. In an agricultural implement, the combination with a frame supported on an arched axle, of vertical racks fixed to the frame, a shaft extending transversely through the frame and supported from the arched axle and carrying segmental gears arranged to engage with the racks carried by the frame, a hand lever fixed on the shaft and arranged to rock the shaft and the segmental gears and to raise the frame vertically, and springs arranged to assist in raising the frame vertically with relation to the axle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HENRY M. PARIS.
