UNITED STATES PATENT OFFICE.

RICHARD H. PURNELL, OFV ROSEDALE, MISSISSIPPI.

COMBINED STALK `CUT'TER AND RAKE.

SPECIFICATION forming part of Letters Patent No. 679,991, dated August 6, 1901. Application filed September 10, 1900. Serial No. 29.601. (No model.)

To @ZZ whom; t may concern:

Be it known that I, RICHARD I-I. PURNELL, a citizen of the United States, residing'at Rosedale, in the county of Bolivar and State of Mississippi, haveinvented new and useful Improvements in a Combined Stalk Cutler and Rake, of which the following is aspeciication.

My invention relates to combined cottonstalk cutters and rakes, one object being to provide a sim ple and effective machine of this character in which the knife or cutter is supported in a substantially horizontal plane without regard to the inclination of the arms which support the cutter.

A further object of the invention is to provide means for preventing `undue lateral strain on the cutter-supporting device and to improve the general structu re of this class of machinery. 1

The construction of the improvements will be fully described hereinafter in connection with the accompanying drawings, which form part of this specification, and their novel features will be particularly pointed out'l in the appended claims.

In the drawings, Figure 1 is a plan view of a combined cotton-stalk cutter and rake embodying theinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a view in perspective of the knife or cutter, showing the under side thereof.V Fig. 4 is a view in perspective of one of the holders or brackets for supporting the rake-teeth, and Fig." 5 'is a transverse vertical section, and Fig. 6 is a longitudinal vertical section with the rake detached. Fig. 7 is a detail perspective view of the lever connection with the yoke.

The reference numeral 1 designates the axle of the machine, carrying a frame 2, provided With a forward extension 2, having par,- allel vertical iianges 3, between which is secured the draft-tongue 4. A seat-standard 5 is secured to the rear end of the tongue 4 and carries a seat 6.

7 and 8 designate brackets projecting upward from the frame on opposite sides of the seat-standard, and each of said brackets is provided with a horizontal sleeve 9, to `which is secured adjustably by means of a pin 10 the upper end of a rod 11.

12 and 13 designate parallel arms formed at their upper ends with sleeves or bearings 14, through which the axle 1 extends, said sleeves or bearings beinglocated upon the axle outside of the brackets 7 and S of the frame 2. These arms 12 and 13 are connected together by a yoke 15, having a central eye or loop 16, through which the axle. 1 passes. The rear ends of the arms 12 and 13 are formed Vwith eyes or loops 17, which serve as bearings for the oppositely-projecting arms 18 of a transverse frame or cutter-bar 19, to the under surfaceof which is secured a knife or cutter 2O by means of bolts 21. This knife is formed with an inclined cutting edge 22 to elfect a shear cut, and from the under side of said cutter depends a wing or blade 23, adapted to enter the ground and take up a portion of the lateral strain uponthe cutter, thus relieving the supporting-arms 12 and 13. .Upon the outer ends of the arms 18 are secured brackets 24, to the upper ends of which are pivotally secured the rear ends of the arms 11, the forward ends of said arms 11 being formed with a plurality of perforations 25 to facilitate the adjustment of the arms with relation to the brackets 7 and 8.

26 designates a lever bifurcated at its lower end and adapted to straddle the segmental rack 27, supported upon the frame and having a downwardly-extending arm 28, connected by means of a link 29 to a bracket 30, secured to the yoke 15. The lever 26 is provided with the usual locking-.dog 31, connected by a pull-rod 32 to a bell-crank lever 33, fulcrumed adjacent to the upper end of the lever 26. The arms 12 and 13 and the cutter carried thereby are adapted to be adjusted by the movement of the lever 26, and the adj ustability of the arms 11 regulates the depth of penetration of the cutter. A characteristic of the improved construction is that the arms 1-1 are substantially parallel to the arms 12 and 13, so that the cutter is maini tained at all timesin a substantially horizoni tal plane.

The rake, which is adapted to be dragged behind the machine, comprises a frame consisting of parallel bars 34, connected by end bars 35, having journals 36 projecting from the outer sides thereof, and a plurality of blocks or holders 37, ione of which is shown detached in Fig. 4. The holders 37 are recessed at their ends to adapt them to fit over IOS the side bars 34: of the frame to which they are bolted, and said holders are also formed with central openings 38, through which the rake-teeth 39 extend. i

Upon lthe journals 36 of the rake-frame are arranged eyes or clips 40, connected by suitable connections 41 to links or eyes 42, mounted upon the axle within the outer ends thereof vinside of the carrying-wheels 43 of the'machine.

The working position of the rake-teeth is best illustrated in Fig. l2 of the drawings, whichshows the rake-teeth supported in inclined position by .means of the rake-frame.

The utility and operation of the machine will `be apparent' from the drawings in connection with the foregoing description, and I will have it understood that I reserve the right to make all such modifications and "ariations in the details of the mechanism as may fall within the scope and spirit of the invention as expressed in the following claims.l

Having thus fully described my invention, what I claim as new', and desire to secure by LcttersPatent, is-

l. In acotton-stalk cutter-,the combination,v

with a supporting-axle; of a frame having brackets projecting upwardly therefrom; -a pair of arms pivotally supported uponsaid axle; a cutter-bar carried bythe rear ends of vsaid arms; parallel arms adjustably secured at `their forward ends to the brackets of the framev and at their rear ends to arms ro- P Jectlng from said cutter-bar; and means for l raising and lowering said arms.

' 2. Inacotton-stalkcutter,the combination,

with a supporting-axle; of a cutter-bar adjustably supported in rea-r of said axle; and

otally supported upon the axle below said brackets; a cutter-bar supported in bearings at the rear ends of said second pair of arms; connections between the ends of said cutterbar and the rear ends of the adjustable arms; a cutter secured to said cutter-bar; and means for raising and lowering said arms.

4. In a cotton-stalk cutter,the combination with a supporting-axle; of a frame having upwardly-extending brackets; apair of longitudinally-adjustablearmspivotallysecured lat their forward ends to said brackets; aseoond pair of arms pivotally secured at their forward ends to said axle; a yoke pivotally supported upon the axle and connecting said second pair of arms; a cutter-bar supported .in bearings at the rear ends ofthe lowerarms;

connections between said cutter-barand the vrear ends of the adjustable arms; alever for raising and lowering said lower arms; and a link connection between said lever and yoke. In `testimony whereof I aiiix my signature in presence of two witnesses.
