I Application led October 25, 1918. Serial No. 259,691.

To all whom t 'may concern:

Be it known that I, DAYTON I-I. GmsoN, a citizen of the United States, and a resident of Rushville, county of Rush, and State of Indiana, have invented a certain new and useful Attachment for Seed-Drills; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This'invention relates to attachments for seeding drills and is designed primarily for use in connection with wheat drills, such as is used in sowing wheat between the rows of standing corn.

The prime feature of the invention is the provision of means for turning down corn or moving same out of the path of the drill as it is moved forward between the rows of corn.

A further feature of the invention is the provision of means for applying the propelling power for the drill at a point in the rear thereof.

A further feature of the invention is the provision of means for bodily elevating the drill when the end of a row is reached, whereby it may be readily turned and entered in the next succeeding space to be drilled.

` A further feature of the invention is the provision of means for regulating the depth -to which the drill hoes may enter the soil.

A further feature of the invention is the provision of means for guiding the drill as `it passes between the rows.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings, which are made a part of this application, Figure 1 is a perspective view of a wheat drill showing the improved mechanism attached thereto, parts being broken away. Fig. 2 is a sidevelevation of the wheat drill and attachments therefor, showing parts thereof in section. Fig. 3 is a top plan view of the mechanism employed for bodily elevating the drill, and to which propelling power is applied. Fig. 4 is a top plan view of the corn turning hood.` Fig. 5 is a rear end elevation thereof and Fig. 6 is a fragmentary top plan view showing the manner of guiding the attachment and the drill to which itis attached.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, l indicates the seed drill, which may be of any preferred make, and having frame members 2, a power wheel 3, furrow making disks 4: and seed containing hoppers 5, said drill being of the variety employed for drilling wheat between the rows of standing corn. When drilling wheat between the rows of standing corn considerable difficulty is encountered by some of the stalks of corn falling over into the spaces between the rows, heretofore requiring some one to precede the drill and turn the stalks of corn, or position them to one side of the path of the drill. To overcome this objectionable feature, and at the same time dispense with the extra helper, a hood or shield 6 is positioned forwardly of the drill 1 and is tapered, or arranged similar to a cow-catcher for a locomotive, the shield being preferably constructed of sheet metal and extending over a frame 7 said frame preferably comprising a strip of metal positioned at the rear en of the shield, a central bar 8 and side bars 9, the shield extending over the center bar Si and having its lower edges attached to the side bars 9. The forward end of the shield 6 is supported by a wheel 10, which is mounted upon a shaft 11, extending through the side bars 9, said shaft being connected with frame 2 by means of straps 12, the upper ends of which are pivoted to the frame members 2 while the shaft 11 passes through the lower ends thereof. By this means the shield is pivoted to the frame of the drill, and although supported at its forward end by wheel 10, the straps 12 project forwardly from the frame members 2 and thus drive the shield forwardly as the drill moves forwardly. The rear portion of the hood 6 is supported from parts of the frame members 2 by hanger bars 13 and as said hanger bars have pivotal connection with their coperating parts the forward end of the shield 6 may swing upwardly or downwardly in conformity with the surface of the ground over which same is traveling. The side bars 9 are elevated slightly above the surface of the soil, and in order to pick up stalks that are lying fiat upon the ground, a guard or nose piece 14 is attached to the forward end of the head and projects below the hood the same distance as the wheel 10 extends below-the hood so that the guide will skim the upper surface of the ground and pick up any stalks of corn that may be lying upon the ground.

IVith this construction as the drill is moved forwardly, the stalks of corn will be picked up by the guide 14, and owing to the contour of the hood or shield the stalks of corn will be moved laterally out of the path of the drill' and deposited adjacent the rows of standing corn, and to prevent parts of the stalks from accidentally swinging inwardly under the outer disk 1, the side bars 9 may be extended rearwardly of the rear edge of the hood, and in addition to this, guide arms 15 may be attached. to and extend rearwardly of the ends of the side bars 9, thus insuring that no parts of the stalks or ears of corn will move into the path of the outer disk.

It is to be understood that the drill may be moved forwardly either by motor power or by draft animal, but in the present instance I have shown means for operating the drill through the medium of a draft animal, and to this end a truck 1G is mounted in the rear of the seed drill 1, the frame 17 thereof being pivotally attached to the rear portion of the frame members 2 of the drill, the wheels of the truck being positioned substantially at the longitudinal center of the frame 17. Extending forwardly from the axle 18 of the truck are rigid rails or bars 19, said rails being pivoted at one end to the axle 18, and at their forward ends to the forward ends of the frame members 2, said rails passing above the frame members 2 and also above the cross bar 20, at the forward end of the frame 17 so that when the rear end Aof the frame 17 is pressed down the cross bar 20 will strike the under face of the rails 19, and as the ends of said rails are anchored the entire drill, together with the shield 6, will be thrown upwardly and disengaged from the ground, and while in this position the truck may be moved forwardly carrying the drill so as to position the drill between new rows of corn, or in spaces not previously drilled.

Pivotally attached to the axle 18 and extending rearwardly therefrom are shafts 21 between which the draft animal is placed for propelling the truck, and drill attached thereto, forwardly, the shafts being pivoted to the axle so that they can be thrown upwardly or downwardly as may be desired. The rear ends of the shafts are connected together by a brace bar 22, to which is attached the usual form of swingletree 23. The

lshafts 21 are exteriorly 0f the side bars of the frame 17, and in order to utilize the shafts as levers for depressing the frame 17 for lifting the drill, which is attached to the opposite.V end thereof, a latch 24 is provided between the shafts 21 and the pivotal connection between the latch and shafts are so arranged that 'when the shafts are thrown upwardly above the rear end of the frame 17, the latch will swing forwardly and assume a vertical position, and when so positioned the lower end of the latch will rest upon the upper edges of side bars of the frame 17 when downward pressure is directed against the shafts 21, and as the shafts are elevated a considerable distance in order to permit the latch t0 swing over the frame 17 they will be in position to apply a strong leverage on the rear end of the frame 17 thus enabling the attendant to readily support the seed drill in elevated position while the same is being shifted from one position to the other at the end of the rows. After the drill has been turned at the end of the field the operator releases the latch 24 by swinging salne rearwardly through the medium 0f a pull rod 25, which extends longitudinally of the shaft to a point adjacent the rear end thereof and in convenient reach of the operator, and as shown in Fig.` 1 when the shafts are lowered to their normal position the end of frame 17 will'hold the latch 1' in inoperative position between the shafts. The inoperative position. of the latch 24 is shown in Fig. 1, while the operative position thereof is shown in Fig. 2.

In order to manually guide the drill as it is moved forwardly, a guide handle 26 is provided, one end of which 1s entered in a socket 27 in the brace bar 22, and as 1t is sometimes necessary for the operator to be adjacent one side of the path of the drill and draft animal in order to obtain a proper View forwardly of the drill, a socket 27 is placed adjacent each end of the brace bar 22, and a guide handle may be. entered in either of the sockets as may best suit the occasion.

. In order'to limit the depth to which the disk 4L may enter the soil a regulating rod 28 is extended across the rails 19 at the rear end of the frame members' 2, said regulating rod being substantially U-shaped, the depending ends thereof being provided with threads 29 which coperate with nuts 30.

The depending vends of the regulating rod pass through the frame members 2, and by placing a nut above and one below each frame member the horizontal portion of the regulating rod may be adjusted to various distances over the rails 19 thus varying the depth to which the disks may enter the soil. The downward movement'of the rear end of the frame members 2 and disks carried thereby is stopped by the horizontal portion of the regulating rod 28 striking the top edges of the rails 19.k l

In operating the device, the draft animal is positioned between the shafts 21 and secured in the usual manner to the swingletree 23, and as the draft animal moves forwardly the drill will likewise be moved forwardly. When the end of the row is reached and it is desired to turn the drill, the operator swings the rear end of the shafts 21 upwardly until the latch 24 swings into position over the rear end of the frame 17, when the operator applies downward pressure to the rear end of the shafts 21 and tilts the frame 17 on the axle 18. As the forward end of the frame 17 is pivoted to the frame members 2 of the drill, and in view of the fact that the rails 19 extend above the cross bar 20 of the frame 17, and are attached at their forward ends to the frame members 2, said swinging action of the frame 17 will result in bodily lifting the drill 1 until the parts thereof and the shield carried thereby are out of contact with the ground, and while still supported in this position the truck may be moved to any desired point, carrying the drill therewith. As soon as the drill is positioned to make thc return trip the operator releases the downward pressure on the shaft 21 and gives a rearward pull on the pull rod 25, thereby releasing the latch 24 and permitting the shafts to resume their normal position.

The invention claimed is:

1. The combination with a seed drill including a frame, of a hood adapted to travel forwardly of the drill for removing stalks of corn that may be in the path thereof, and means for yielding attaching the hood to the frame of the drill.

2. The combination with a seed drill, including frame members, of a tapered hood adapted to travel forwardly of the drill,
