JOHN F. BOYD AND JOHN FRAZIER, OF RUSHVILLE, INDIANA.

ATTACHMENT FOR GRAIN -DRILLS.

Specification of Letters Patent.

Patented June 18, 1918.

Application filed February 2, 1918. Serial No. 215,132.

To all whom it may concern.

Be it known that we, JOHN F. BOYD and JOHN FRAZIER, citizens of the United States, residing at Rushville, in the county of Rush and State of Indiana, have invented new and useful Improvements in Attachments for Grain-Drills, of which the following is a specification.

This invention relates to an attachment for grain drills that is used for planting wheat or other grain in corn fields, the purpose of the attachment being to lift corn stalks that have fallen down to an out-ofthe-way position where they will not obstruct or be injured by the passage of the grain drill.

The invention has for its object to provide a hood or attachment of the class described .whichwill be simple in construction, durable, easily applied and effective in operation,

A further object of the invention is to provide a simple and improved device of the class described which when occasion demands may be readily moved to an out-ofthe-way position for traveling over the roads.

With these and other ends in view which will readily appear as the nature of the invention jisbetter understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings:

Figure 1 is a side view showing the device applied to a conventional grain drill parts of the device having been broken away.

Fig. 2 is a front view of the same.

Fig. 3 is a top plan view of the hood or device detached.

Fig. 4 is a longitudinal sectional view of the same.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame structure of the improved device comprises a bottom rail 15 formed of angle iron or steel, the same being bent to an approximate U-shape. Riveted or other wise secured on the vertical flange or web of the base rail are uprights 16 of the flat iron or steel, said uprights being of different heights, the same increasing in height from the free rearward ends of the limbs of the U-shaped base rail and toward the bridge portion at the front end of said rail. Secured on the upper ends of the uprights 16 is a top rail 17 consisting of a strip of flat iron or steel which, owing to the variation in the height of the respective uprights, will occupy a downwardly and rearwardly inclined position with respect to the base rail.

The uprights 16, or some of said uprights, may be reinforced intermediate their upper and lower ends by a reinforcing strip 18 as best seen in Fig. 4. Bolted or otherwise secured on the base and top rails as well as on the uprights and the reinforcing strip is a hood 19 which will be preferably constructed of galvanized iron of suitable gage, said hood conforming to the conformation of the frame being of substantially U-shape when seen from the top and with its side portions or wings tapering downwardly and rearwardly. The hood is provided in the forward portion thereof with a vertical slot 20 reinforced by a frame 21 of strips of iron or steel.

Grain drills which are specially constructed for planting grain in fields of standing corn are usually provided with furrow openers consisting of shovels or disks, a disk having been shown at 22 in Fig. 1. Such grain drills are also customarily equipped with a vertically disposed draft bar 23 having a clevis 24 for the adjustment of which the draft bar is provided with a plurality of apertures 25. The improved attachment is mounted in position on such a drill by means of the bolts 26 on which the outermost disks are mounted for rota tion, bolts of extra length being provided for this purpose and the base rail being provided at the rearward end of each of its limbs with an opening 27 for the passage of such bolt. The rearward upright 17 rising from each limb of the base rail is preferably equipped with hooks 28 adapted to engage and to rest upon parts of the frame of the grain drill, it being obvious that for different makes of ain drills different supportin means will be provided. In any case, owever, pivotal supporting means drill to i on uneven'roads without being obstructed thereby. Theslots 20 in the front portion should be provided for the rearward ends of the limbs of the base rail and additional supporting meansshould be provided for supporting the hood in proper position with its forward end raised slightly above the ground. When thus mounted, as seen in Figs; 1 and 2,'the draft clevis of the grain drill should project through the slot 20 in the forward end of the hood and it will be obvious that as the ain drill thus equipped moves forwardly, c lbwn stalks will be engaged by the hood and pushed in the proper direction without injury.

The hood 19 is provided near its forward end with a cross bar 29 with which is connected a rod or chain 30 having a hook 3-1 which may be engaged with one of the apertures 25 in the draft-bar 23 for the purpose of assisting in sustaining the hood in position for operation. By shifting the hook to an aperture nearer the upper end of the draft bar theliood will beraised suififrom the ground to enable the ground ciently which the hood is mountedjto travel of the hood is'obviously to bemade sufficiently longto enable such adjustment of the hood to take,

Having described the invention what we claim as new is:

1. A device of the class describedjcomprising a U-shaped base'rail, a U-shapedtop rail, uprightssupporting the top rail in downwardly and rearwardly" inclined position with respect to the baserail and" a U-shaped hood supported on the frame structure, the wings of said hood being tapered'rearwardly and downwardly;

2. A device of the class described, comprising a U-shaped base rail,a U-shaped top rail, uprights supporting the top rail in downwardly. and rearwardly inclined position with respect to the base rail and a U-shaped hood supported on the frame structure, the wings of said hood being tapered rearwardly and downwardly, and means engaging the rearward ends of the limbs of the base rail for pivotallysupporting the device on a grain vdrill.

3. A- device. of the class described, comprising a U-shaped base rail,'a U-shaped top rail, uprights supporting the top rail 1n downwardly and rearwardly inclined posi- 'tion' with respect to the base rail and a U-shaped hood supported on the frame.

structure,- the wings of said hood being tapered rearwardly and downwardly, and

means engagingthe rearward ends of the limbs of the base'rail for pivotally supporting the device on a grain drill; the hood being provided with a: vertical slot at the forward end thereof-for the passage of the draft clevis of the drill.

4L A coin stalk lifting attachment for grain drills' comprising a hood substantially U --shape in plan and ha'Ving forwa'rdly" converging sides, said hood having an opening at its front end for the passage of the draftflclevis of the drill and I being provided with means whereby said hood may-besecured to the drill and-*carried thereby.
