CULTIVATOR.

Specification of Letters Patent.

Application led March 3, 1913.

. Patented Aug. itil, 19114. serial No. 751,768.

To all whom it may concern Be it known that I, ALExUs C. LINDGREN, a citizen of the United States, residing at Moline, in the county of Rock Island and State'of Illinois, have invented certain new and useful Improvements in Cultivators, 0f-

' the rows at the outer sides 0f the wheels.

An equalizer thus hitched, while possessing the advantage of avoiding or straddling the -rows pf plants, is objectionable in the reweight, it hasbeen customary to employ aA tongue truck consisting usually of one or two swiveling wheels so connected to the machine as to give support to the tongue,

and in this manner prevent the weight from coming on the horses necks. This expedient has also been found to be objectionable when the machine is turned at the ends of the rows, or when the machine is backed up as most farmers do,"after making the turn, the wheels of the truck in such operations assuming bad obstructing positions, and frequently being twisted out of shape.

t is the aim of the present invention to avoid these objections attendant upon the use of tongue trucks, and the invention co-nsists in so connecting the truck to the machine that it may be moved or shifted from its supporting, operative position to an inoperative position where it Iwill not interfere with the turning or backing or other movements of the machine.

More specilicall the invention consists in securing the truc to the machine so that it may be raised clear of the ground, and in providing a lever mechanism within reach of the driver, by means of which the truck may be elevated when the machine is turned or backed, so as not to interfere with these movements. Inasmuch as the neck weight of the tongue on the team is only felt when the team is pulling with the cultivating tools 1n action in the ground, which conditions do not obtain when the machine is being turned or backed, it is manifest that the tongue needs no support atsuch times; hence I am enabled by my improved construction to secure all the advantages of a high hitch, and at the same time avoid all the objections of a tongue-supporting truck.

In the accompanying drawings I have shown my invention embodied in the fgrm whichat the present time I deem the 'most suitable for realizing the objects and advantages sought, but it will be understood that the construction may be variously changed and modified within the skill of the mechanic without departing from the limits of my invention; and further, it will/be understood that the invention is not. limited to any particular form or construction of the parts, except in so far as/such limitations are specified i the ,claimsz/ l In the accompanying/drawings: Figure l is a top plan View ofa two-row cult-ivator, having my invention embodied therein; Fig. 2 is a side elevation of the same, with the tongue-supporting truck in its lowered operative, supporting position, as it appears when the machine is being drawn through thefield with the cultivating tools in operation; and Fig. 3 is a similar view showing kthe supporting truck raised fromA the ground to Van inoperative position.

Referring to the drawings, l-represents the frame of a two-row cultivator, which frame comprises a transverse frame-bar 2, to the ends of which carrying-wheels 3-3 1are connected, preferably in such manner that they may swivel or rock on vertical axes in order to enable the machine to be i accurately guided in following deviations in the rows o plants. This frame-bar has the rear ends of two draft tongues 4 4 connected xedly to it, which tongues extend forwardly and are suitably braced to thek lframe-bar by means of diagonally-extend- .ing braces 5, 5 and 6, 6, connected at'their forward ends to the opposite sides of the tongues, respectively, and connected at their rear ends to the transverse frame-bar. The transverse frame member with the two tongues lixedly connected thereto, as described, constitutes in effect a rigid cultivator-frame, which frame gives support to 1 suitable cultivator beams 7 7, etc., equipped with the usual cultivating tools. A short distance in advance of the transverse frame member, a long transverse bar 8 is provided, which is fixed y connected to the two tongues and carries idler pulleys 9, 9 on its ends, around which an evener chain 10 passes, and has connected with its opposite ends double trees 11, 1l, each equipped with two swingle trees 12, 12, for the attachment of the draft animals.

14 represents a tongue-supporting truck, in the present instance comprising two wheels 15, 15, mounted on the ends of a transverse axle 1G having fixed to it between its ends a fore and aft extending collar 17 containing in its side a circumferential slot 18. Within this collar is loosely mounted the rear end of a horizontal fore and aft extending stem 19, which is confined in the collar by means of a pin 20 extending outwardly from the side of the stem and through the slot 18, this arrangement limlting the rocking movement ofthe axle and wheels on the stem. At its forward end the stem is provided with a vertical stud 21, mounted to swivel in a vertical bearing opening in a bracket member 22, which bracket member is formed with a rearward extension 23, having depending stops 24 at its ends adapted to be engaged by the stem 19 and limit the motion of the same as itswings back and forth horizontally around the vertical axis of the stud. The bracket member has rigidly fixed to its opposite sides the rear ends of hanger bars 25, 25, which bars extend forwardly, upwardly and outwardly, and have their forward ends pvoted by means of horizontal transverse pivot pins 26, 26, to fixed lugs 27, 27, depending from the under side of a bar 28 fixedly connected to the under sides of the two tongues some distance in advance of the long bar 8 before alluded to. At its rear end the bracket member 22 has connected rigidly with it the forward end of a fore and aft extending bar 29, which extends rearwardly and upwardly ,and is pivoted at its rear end between the rear ends of two brace bars 30, 30, extending forwardly with their forward ends pivoted as at 31, 31, to the hanger bars 25, 25, respectively, adjacent the point of connection of these hanger bars with the lugs 27.

From the construction ."escribed it will be seen that the sup orting truck is located some distance in avance of the carrying wheels of tbn cuitivator, and is so connecte with tlc cultivator-fi l. ne that it will give support to the draft tongue, while at the same time it is capable of a vertical movement with reference to the frame.

A vertical link 32 is pivoted at its lower end at the junction of the brace bars 30 with the bar 29, and is pivoted at its u per end, as at. f 32', to the lower end of a and lever 33,

pivotally mounted, as at 34, on a standard 35 rigidly connected with the frame of the machine, the said hand lever being provided with the usual locking dog 36 adapted to engage in notches 37, 37, in a segment frame 38 connected with the standard 35.

From the construction described, it will be seen that the tongue truck is connected with the frame of the machine at a point where it will give support to the tongue as the truck travels over the surface of the ground in the position shown in Fig. 2. Further, it will be seen that the truck may be elevated bodily free of the surface of the ground by means of the hand lever mechanism, and locked in an elevated position, as shown in Fig. 3. When the cultivator is in action, with the cultivating' tools in the ground and the machine being drawn by the draft animals, the truck is locked down in operative supporting position by means of the hand lever and its connections, as shown in Fig. 2, and in this position it will prevent the draft on the evener mechanism from causing the neck weight of the tongues to be imposed on the draft animals. Whe-.1 the end of the row being cultivated is reached and the team is turned, the strain on the frame being relieved, the tendency to neck weight is also relieved and the drlver, by unlatching the hand leverand drawing the same toward him, may lift the truck bodily up- 'ward to an inoperative position free of the surface of the ground, as shown in Fig. 3. This will enable the team to be turned freely without obstruction, and also will enable the same to be backed up in starting on the new row, without obstruction being offered by the truck. In starting down the second row, the hand'lever is again unlocked and pushed forwardly, with the result that the truck will be lowered to its former operative supporting position, in which position it will sustain the tongues and prevent the neck /weight from being imposed.

In the operation of the machine with the tongue truck in its lower supporting position, .the latter, due to its swiveling action, will act as a caster wheel and hence will not interfere. with the accurate guiding of the cultivator-frame, '.'hich in the present instance is accomplished by the manipulation of the swiveling carrier wheels before alluded to.`

It will be manifest that while I have shown my invention as applied in connection with a special form 0f two-row cultivator, the invention is applicable as well to other forms of cultivators and like machines, the

essence of the invention residing in the provision of a supporting device or truck adapted, when the machine is in normal operation, to support the draft tongue or device so as to relieve the neck weight on the draft animals, and adapted to be moved from its sup- License porting position to an inoperative position where it will not interfere with the turning or backing or like movements of the machine.

Having thus described my invention, what I claim is l. In an agricultural machine, the combination of a wheeled frame, a ldraft tongue extending forwardly therefrom, a supporting device connected thereto and adapted when the machine is in operation to travel along the ground and give support to the said draft tongue, said supporting device being movable relatively to said tongue and frame to inoperative non-supporting position when the machine is out of operation, and means for controlling the movements of said supporting device.

2. In an agricultural machine, the combi- .nation of a wheeled frame, a draft tongue extendingv forwardly therefrom, a wheeled truck connected thereto and adapted, when the machine is in operation, to give support to the draft tongue, said truck being movable upwardly relatively to said tongue and frame to inoperative non-supporting position when the machine is out of operation, and means for controlling the movements of said truck.

3. In an agricultural machine, the combination of a wheeled frame, a draft tongue extending forwardly therefrom, a wheeled truck connected thereto in position to give' support to the tongue when the machine is in operation, said truck being freely movable about an upright axis situated in advance of the axis of its wheels, and means for moving said truck relatively to the frame and tongue to an inoperative nonsupporting position, when the machine is out of operation.

4. In an agricultural machine, the combination of a wheeled frame, a draft tongue extending forwardly therefrom, a swiveling 'truck connected thereto and adapted to give support to the tongue when the machine .is

in operation, said truck being movable relatively to the frame and tongue up and down, and means for controlling the up and down movements of said truck.

5. In an agricultural machine, the combination of a wheeled frame, a draft tongue extending forwardly therefrom, a wheeled truck connected thereto and movable up and down relatively to the tongue and frame about an axis situated in advance of the axis of the truck wheels, and means for controlling the up and down movements of said truck.

6. In an agricultural machine, the combination of a wheeled frame, a draft tongue extending forwardly therefrom, a tongue supporting device adapted to travel along the ground and give support to the tongue, hanger bars connected at their rear ends with said supporting device and pivoted at their forward ends to the draft tongue, whereby the said supporting device is movable up and down relatively to the tongue and frame, a lever mechanism on the frame, and connections between the lever mechanism and the supporting device.

7 In an agricultural machine, the combination of a wheeled frame, two draft tongues connected rigidly thereto and extending forwardly therefrom, awheeled truck connected thereto between the tongues and adapted to give support to the tongues to relieve the neck Weight on the animals when the machine is in operation, the said truck being movable up and down relatively to the tongues and frame, and means for controlling the up and down movements of said truck.
