.MACHINE FOR PULLING STALKS-Q i SPECIFICATION forming part of Letters Patent No. 760,877, dated May 24, 1904. 1

Application filed July 2, 190a Serial- Nof164p44. (N model.)

re ally/ham it may concern:

.. Be it known that I GEOR E MIL'roN KIRK? PATRICK, a citizen of-the United States, and a resident of- Ennis, in the county of Ellis and State of. Texas, have invented a new and Improved Machine for Pulling Stalks, of which the following is a full, clear, and. exact description.

-The purpose of the invention is to provide a machine especially designed for pulling up corn and cotton stalks by the roots and break: ing the stalks in small pieces when desired and to provide a construction of the character described which will. be simple, durable, and economic and wherein the stalks will be guided to the pulling-section of the machine, and the pulling-section may be adjusted to suit the average height of the stalks and bodily raised and lowered at any time to permit the pulling-section to be carried out of the way of obstructions when occasion so demands.

- The invention consists in the novel constructionand combination of theseveral parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings,- forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figuresx Figure 1 is a plan view of the machine. Fig. 2 is a transverse section through the pulling cylinders or drums, illustrating the application of cutters to one of them. Fig. 3 is a transverse section through the pulling cylinders or drums, the I cutters being omitted.

Fig. 4 is a longitudinal vertical section taken' practically on the line 4.4 of Fig. 1. Fig. 5 is a detail View of a bearingwbox for one of the pulling cylinders or drums anda controlling-spring for the box, and Fig. Grepresnts plan and endyiews of the pulling-slats and the cutters employed in the construction of the pulling drums or cylinders.

. Theaxle is provided at each end with a loosely-mounted supporting-wheel 11, and these wheels have suitable boxes at their inner faces concealing pawl-and-ratchet connec- -or tongue.

tionsof the usual type between the said wheels and the axles, so that the axle 10 will be turned by the driving-wheels only when the machine "is drawn forward.

The axle 10.near each end passes through

bearings

13 and 14, and the side pieces 15 of the forward frame-section A are secured. to the upper portions of the outer bearings 13,

thus bringing the axle 10 below the said forard section A of the frame. 15 of. this forward frame-section extend rearwardly a desired distance beyond the axle, and the forward members 16 of the said forward frame-section are more or less curved and are connected at their innerends to opposite sides of the pole or tongue, which extends horizontally rearward to therear end of the said forward frame-section, and a drafttree I 18 is pivoted on the tongue 17 being usually connected by chains 19 at its ends with theforward members of the forward framesection A. 7

The rear frame-section B, completing the main frame of the machine, consists of side pieces 20, which at their foward ends are secured to the upper faces of the inner bearings 14, and adjacent to these bearings 14 the side pieces 20 are curved or inclined downward, as is shown at 21 in Figs. land 4; but for the remaining portion of their length the said side pieces 20 are practically straight, and

they extend a predetermined distance beyond the rear of the supporting-wheels 11. The side pieces 20 of therear frame-sectiQn-are connected at their rear ends by parallel crossbars 22 and betweentheir centers and their forward ends by similar parallelbars 23,- as is shown in Figs. 1 and 4.

In -order to strengthen the rear'portion of the forward frame-section A, an arched connecting-bar 24 extends from .one side 15 to the other and is-provided, preferably, with a central member extending down to the pole The drivers seat 25 is supported by a suitable spring-shank 26, and this shank is preferably attached to the tongue 17.

Bearings 27 are located near the left-hand The side pieces ends of the

parallel cross-bars

22 and 23, the bearings 27 being secured to the said crossbars, so as to be stationary, and near the opposite ends of the said

cross-bars

22 and 23 other bearings 28 are slidably mounted on the said cross-bars. These latter bearings, as is shown in Fig. 5, preferably consist of an upper section 28 and a lower section 29, adapted to enter the spaces between a pair of cross-bars, and at the bottom of the lower section 29 a flange 30 is formed at eachside, so as to prevent the bearings from accidentally being drawn from engagement with the cross-bars, yet permitting the bearings to slide freely thereon. Bolts 31 are employed to connect the two sections of the bearings 28, so that by loosening the bolts 31 the lower section of the bearing will drop from the upper one, thus permitting the hearings to be readily detached from their supports.

At the left-hand side of the rear section B of the frame between the cross-bars 22 and 23 a pulling drum or' cylinder C is mounted to turn, and adjacent to the right-hand side of the said rear frame-section, also between the

cross-bars

22 and 23, a second pulling cylinder or drum C is mounted to rotate. Each drum or cylinder consists of a series of spoked wheel's32, having central rectangular openings therein, and through the walls of the cylinder or drum C the rectangular portion of a shaft c is passed,which shaft is cylindrical at its ends and is journaled in the fixed bearings 27 while the shaft 0 for the drum or cylinder C is journaled at its ends in the sliding bearings 28, as is shown in Fig. 1. A series of slats 33 is located on the peripheral portions of the wheels of each drum or cylinder, completing the construction thereof, and these slats 33,which may be termed pulling-slats, are constructed as is shown in Fig. 6, having their ends 34 flattened and provided with apertures 35, whereby the said slats may be secured to the peripheral portions of the end wheels 32 by bolts, screws, or their equivalents. The body portions of the slats or the portions between the ends of a slat are semicircular, as is shown at 36 in Fig. 6. slats 33 are so spaced that the slats of one cylinder enter the spaces between the slats of the opposing cylinder, and the slats act as gear-teeth, sothat one cylinder imparts movement to the other, and the cylinders turn in opposite directions, both, however, in direction of the space between them. These cylinders or drums are open at each end, and the spaces between the slats enable the dirt and small stones that may be raised to drop into the cylinders or drums and pass out through their bottom portions or at their ends, thus keeping the cylinders or drums free from obstructions.

It 'isnecessary that one of the cylinders or drums should be tension-controlled with -re- These spect to the opposing drum or cylinder, so that when the thick butts of stalks pass between them one of the cylinders will give, so as to permit the ready upward passage of the stalk. Therefore the cylinder 0 is made movable to and from the cylinder 0, and one end of a spring 39 has bearing against the outer end of each of the sliding boxes 28, the other end of each spring having bearing against a block 40, held to slide in the spaces between the pairs of

cross-bars

22 and 23. These blocks 40 are held in adjusted position by suitable bolts 41, screws, or the like, passed into the blocks through slots 42, made in the crossbars, as is indicated in Fig. 5. Under this construction it will be observed that greater or less tension may be brought to bear on the movable drum or cylinder C, as may be required.

When it is desirable to cut the stalks in lengths as the stalks are pulled, one of the drums or cylindersthe drum or cylinder C, for examplehas sundry of its pulling-slats 33 removed and cutters 37 substituted, as is shown in Fig. 2, one of the cutters being shown in detail in Fig. 6. These cutters are likewise flattened at their ends and are provided at such points with apertures for fastening devices, and the body portion of the cutters is more or less triangular in cross-section, as is shown at 38 in Fig. 6. The pulling-slats 33 may be made of wood, although metal is preferably used for the purpose; but the cutters 37 are made exclusively of metal.

The stationarily-mounted drum or cylinder (1 is provided at the forward end of its shaft 0 with a beveled pinion 43, which meshes with a beveled gear 44, loosely mounted on the axle 10, and the inner face of the hub of this beveled gear 44 is provided with a clutch 45, mounted in the usual manner to slide upon the axle 10 or to turn therewith. This clutch 45 is operated through the medium of a footlever 46, having a suitable span connection with the clutch, whereby the clutch may be brought into or out of engagement with the aforesaid wheel 44, which may be termed the driving-wheel.

A hand-lever 47 is pivoted in the tongue 17 and extends above and below said tongue. The hand-lever carries asuitable thumb-latch 48, which engages with a rack 49, also carried by the tongue 17, as is shown in Fig. 4. Atthe lower end of the hand-lever 47 a chain 50 is attached and extends rearward over a pulley on the tongue 17 to a connection with the center of the forward bars 23 of the rear frame-section B. 9

By means of the hand-lever 47 it will be observed that the rear frame-section B may be raised and lowered, and consequently the pulling cylinders or drums C and C may be raised and lowered from or to the ground, as occasion may requireas, for example, in

avoiding an obstruction and bringing the drums quickly down to operative position again after the obstruction-is passed. r

The rear end of the rear frame-section B is adjusted separately, so that in operation the drums or cylinders C andC may be brought nearer to or farther from the ground in the following manner: Bearings 51 areattached to the rear member of the rear cross-bars 22, and in these hearings the shanks 52 of casterwheels 53 are looselymounted, and above and below the saidv hearings on the said shanks 52 of the caster-wheels sleeves 54: and 55 are located, being adjustably secured to the shanks 52 by set-screws or their equivalents.

In order that the stalks may be accurately directed to the contacting-points between the two drums or cylinders C and C, I employ what I term gathering-arms 56, which are attached usually to the rearv end of the forward frame-section A at each side of the tongue or pole 17 and are carried forward beyond the front end of the said frame, where the arms 56 are curved outwardly in opposite directions, forming directing members 56, as is particularly shown in Fig. 1. I

The machine is operated by the driver from his seat and is of simple and durable construction, as one man and one team can operate the machine under all circumstances. The cylinders or drums C and C commence to pull the stalks at their tops, thus uprooting them, and should the stalks break off during the gripping and pulling operation the cylinders will continue to take hold of the stalks'unless they should break off near to the ground. As has been stated, by reason of one drum or cylinder being tension-controlled and having sliding movement relativeto the other ample space is provided between the two drums or cylinders for the ready passage of the thick sections of the stalks, and the cylinders or drums will continue to take hold of the stalks unless they should break off near to the ground. The gathering-arms 56 gather and convey the stalks to the point of contactbetween the pulling'dr'ums or cylinders, which immediately draw them from the ground.

The machine does not require a skilled person to operate it and can be driven over stumps or other obstructions by operating thehandlever 47. All parts are interchangeable, and therefore can be easily repaired and parts substituted. The pulling device may be readily raised and lowered as occasion may demand and operated at any desired height from the ground. It will be understood that changes in the form and proportions of the minor details of construction may be resorted to without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
