FLOW ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 758,981, dated May, 1904. Application lecl November 24, 1903. Serial No. 182,483. (No model.)

T all whowt it may concern:

Be it -known that I, EDWARD M. LANDrs, a citizen of the United States, residing at Brill'- hart, in the county of York and, State of Pennsylvania, have invented new and useful Improvements in Plow Attachments, of which the following is a specification.

This invention relates to plow attachments, and more particularly to means, in connection with a plow-beam, for regulating the penetration of a plow point and share for forming a furrow of an even depth or to control the degree of penetration of a plow-point in view `proved attachment applied thereto.

of certain soil conditions and requisites in different planting operations.

' The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of a plow-beam, showing the im- Fig. 2 is a transverse vertical section through the beam and a portion of the attachment as shown by Fig. 1. Figs. 3 and 4 are detail perspective views of different parts of clips attached to the beam. Fig. 5 is a` detail perspective View of an adjustable hanger for one of the wheel-supports. Fig. 6 is a detail perspective view of a portion ofthe wheel-support engaged by the hanger shown by Fig. 5.

Similar numerals of 'reference are employed to indicate corresponding parts in the several views. v

The numeral 1 designates a plow-beam which may be Lof any suitable length or contour, and on each side thereof is secured a supporting-plate 2, having terminal ears 3 in reverse position, the said ears being connected by cross-bolts 4, respectively disposed above and below and held in close contact with the upper and lower edges of the beamto prevent the said plate from falling out of place or in any manner moving in a vertical direction in relation to the plow-beam. Secured to each supporting-plate 2 is a guide-clip 5, having a central outward projection 6, inclosing a vertical guide-slot 7, opening out through the side of the clip which bears against the plate 2. Each clip also has end ears or securing extensions 8, with openings 9 therethrough to receive bolts or analogous fastenings '10, which are passed through openings 11`in each plate. The outward projection or offset 6 of the guide-clip 5 has a central opening 12 formed` therein to receive a set-screw 13. The guide-clips 5 are applied at dierent points on their supporting-plates, or, in other Words, one is in advance of the other, as 4clearly in# dicated by the position of parts shown in Fig. 1, and by having the endfastenings of the guide-clips pass through the plates 2 into the beam the said plates are prevented from having longitudinal movement on the beam.

The guide-clip on the right side of the beam, as indicated by Fig. 2, is adjustably engaged by a vertically-disposedhanger-bar 14, rising from a'wheel-support 15, having a socket 16 at its outer end, with a set-screw 17 disposed therein. In the opposite clip a vertical hanger-bar 18 is adjustably mounted and has a lower foot 19 resting on a wheelsupport 20, also provided with an outer socket 21, having a set-screw 22, the socket 21 and set-screw 22 being similar to the socket 16 and set-screw 17 on the wheel-support 15. The wheel-support 20 is in the form ofl a flat bar, as shown by Fig. 6, having a longitudinal slot 23 in its inner extremitypand lower nut-guarding flanges 24. 'Ihe foot 19 has side flanges 25, which partially embrace the opposite side edges of the support 20, and

said foot is adjustably connected to its support by adjusting bolts and nuts '25, as clearlyv shownl by Fig. 2. -The wheel-support 20 is adjustableinwardly and outwardly Ion the foot 19 to vary the distance between the wheels carried by the two supports and accommodate a variation in the distance apart of the furrows formed by the plow, which will be'attached to the beam in any suitable manner and forming no part of the present invention. The wheel- supports 15 and 20 are adapted to have wheels 26 and 27, respectively, attached thereto, the wheel 27 being of materially less diameter than the wheel 26. The wheel 27 `is adapted to travel on the unplowed ground, and the wheel 26 is intended to follow the furrow and move in close contact.

In pracwith the vertical wall of the latter.

IOO

tical use the wheel 26 will be projected materially below the wheel 27, and the degree of depression of said wheel 26 .will depend entirely on the depth of the furrow formed. The vertical adjustment of either wheel-support 15 or '20 may be readily attained by loosening either of the set screws 13 and again tightening the same after the desired adjustment has been made.

The wheel 26 may be applied to the support 20 and the wheel 27 to the support 15, as both wheels are secured in relation to their supports by similar means, which is readily interchangeable.

Each wheel has its hub engaged by an axle plug or stub 28, which is inserted through the hub thereof into the socket carried by the outer end of the support and held against separation by the set-screw engaging said socket. The outer extremity of the plug or stub 28 is formed with a head 29 to hold the wheel in operative relation to its support, and after the parts are assembled either wheel is free to rotate on its plug or stub. To relieve each plug or stub of a material portion of the strain which would otherwise be solely concentrated on the said plug through the operation of Vthe wheel, the hub of the latter has an annular flange 29, embracing the outer extremity of the socket 21. This construction is similar in both wheels.

The improved plow attachment also adapts a plow having the same thereon for use on uneven surfaces or inclines, though it is particularly advantageous in plowing iields or land in furrows and regulating the depth of penetration of the plow-point, as well as serving as a guide for the straight formation of each furrow.

Changes in the proportions, dimensions, and minor details may be resorted to without in the least departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new isw l. The combination with a plow-beam, of

supporting-plates applied to the opposite sides thereof and having guide-clips thereon, the guide-clips of one plate being in advance ol the other, cross-bolts extending through the plates above and below and held in close contact with the upper and lower edges of the beam, a vertically-disposed hanger-bar engaging one clip and having a wheel-support atits lower extremity at right angles thereto, said hanger-bar being adjustable and frictionally held in. its clip, a vertical hanger-bar adjustably mounted and frictionally held in the other clip and provided with a lower foot, a wheelsupport secured against the said foot, the hanger-bars being rendered movable in the clips without detaching the plates from the beam, and wheels differing in diameter and interchangeablysecured on the wheel-support.

2. rlhe combination with a plow-beam, of

supporting-plates applied to opposite sides of the beam and having terminal ears in reverse position, cross-bolts extending' through the said ears above and below and held in close contact with the upper and lower edges ol the beam, a guide-clip secured to each supporting-plate and having a vertical guide-slot which opens out through the inner side of the clip, the supporting-plates forming the inner closing means for the slots of the said clips, a vertically-disposed hanger-bar having a wheel-support at its lower extremity at right angles thereto, the said hanger-bar-being adjustable in one of the clips and frietionally held in the latter, a vertical hanger-bar adjustably mounted and frictionally held in the opposite clip and having a lower foot, a wheelsupport adjustably secured against the said foot, and wheels diifering in diameter and interchangeably secured on the wheel-supports.

In testimony whereof I aiiix my si gn atu rc in presence of two witnesses.
