PLOW.

To all ttl/omit may con-cem:

Be it known that I, ARTHUR E. BosT, a citizen ot the United States, residing at Waelder. in the county of Gonzales and State of Texas, have vinvented new and useful Improvements in Plows, of which the following is a specification. e

This invention relates to that class of plows in which the foot is tiltably supported so as to enable' the earth engaging blade to be presented at various angles with respect to the'surface of the ground.

The main object of the present invention isto provide a simple and improved construction whereby when the plow foot is tilted it will at the same time be moved upward or downward according tothe direction in which it is tilted so as to preserve the point of the earth engaging implement at the same level.

A further object of the invention is to produce a plow having a heel plate or runner and a tiltable foot on which the earth engaging blade is mounted, the construction Abeing such that the point of the blade will lremain substantially in the same plane as the lower edge of the heel plate or runner at all adjustments of the tilting foot carrying the said earth4 engaging blade.

lVith these and other ends in -view which willv readily appear as the nature of the 1nvention is better understood, the same consists in the improved constructionand novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a plow constructed in accordance with the inventioniwith dotted lines indicating a different position of the tilting'it'oot.' Fig. 2 is a top plan view. Fig. 3 is a sectional view taken through the tilting foot on the line 3 3 in Fig. 1. Fig. 4t is a sectional detail view taken on the line 1 -11sin Fig. 1. Fig. 5 is a sectional detail view taken on the line 5&5 in Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference. The'invention in the present instance has been shown appliedV to a metallic plow beam 7 having a downturned standard 8 having at its lower end a flattened foot portion 9'on which the heel' plate or runner 10 is secured by fastening means, heel plate orrunner having at its front end an upwardly extending nose piecei 12.

cured adjacent to the opposite sides or faces of the standard bymeans of a bolt 13 eX- tendmg therethrough just above thefoot piece 9 are angle braces 14 the rear ends of which serve for the attachment of'the lower ends of the handles 15. The forward ends the upper end of the nose piece 12 by means of a bolt 16 extending transversely therethrough.

The plow foot -F is composed of two spaced bars 17 vhaving slots 18 whereby said bars are mounted upon the bolt 16 so as to be capable of a sliding movement on said bolt, it being noticed that the Abars 17 are spaced apart by the upper end of the nose piece 12, each of said bars being positioned intermediate the nose piece and the forward end of one of the angle brac'es 14.. Thebolt 16 may be provided with a jam nut or Ilock nut 19, and in assembling the parts care is taken to avoid tightening the nut tosuchl an extent as to interfere with the reasonable free sliding movement of the plow. foot with respect to the bolt 16 which extends through the slots in the spaced bars of the plow toot.V Said spaced bars arejalso'conbolts 2O having'spaeare positioned adjacent to opposite sides of the standard 8 which is loosely"engaged thereby. e

The plow beam supports a plate 22 having an arcuate notched edge forming a segment rack 23. l Fulcrumed on the plate 22 concentrically with the rack 23 is a V-shaped lever onbell crank L, the long arm of which 24 constitutes a handle, said handle being connected with the shortarm 25 by means of a. brace 26. The nlever arm 25'and the brace 26 are positioned adjacent to opposite sides of the upper end of the plow foot with which said arm and brace are connected pivotally by means of a. bolt 27 which may be provided with a spacing sleeve 28. The long arm which forms the handle of the lever is'provided with a suitable spring actuated stop member 29 engaging the rack 23 forthe purpose .of retaining the lever and related parts securely at various adjustments.

The plow handles 15, the lower ends of which are secured upon the angle braces 14, are connected together near their upper ends Said handles are also connected with the plow beam by means of pivot member or 'of the angle braces 14 are connected with y lll) braces 3l that are securely connected with the beam by means of a bolt 32 passing transversely therethrough a short distance in advance of the plate 22 which constitutes the lever stand. A ground engaging blade 33 of any suitable type may be secured on the plow foot-at the lower end of the latter by means of a bolt 34. f

From the foregoing' description, taken in connect-ion with the drawings hereto annexed, the operation and advantages of the improved plowwill be readily understood. The heel plate or runner, as is well known, is used for the purpose of maintaining the plow at an even depth. In order to do this successfully, it is obviously necessary that the said heel plate should run in the bottom of the furrow,and it must, therefore, be maintained in substantially the same relation to thepoint of the earth engaging blade in any position to which said blade may be tilted. Various characters and conditions of soil make it necessary to frequently tilt the blade so as to change the angle thereof with respect to the surface of the ground, b ut such tilting, if the plow foot be simply rocked about a stationary axis, would result in raising or lowering the point of the blade with respect to the lower edge of 4the heel plate. By. the present construction7 when the lever L is rocked to tilt the plow foot,

said plow foot will at the same time be slid or moved upwardly or downwardly, according to the direction in which the lever is tilted. The part-s of the plow' structure are so arranged and proportioned that when the upper end of the plow foot isrocked in a forward direction, thus tending to swing the lower blade carrying end downwardly and rearwardly, the plow foot will at the same time be slid or moved upwardly to an extentsulioient to compensate for the downward movement of the lower end thereof, thus causing the point of the earth engaging ,blade to be maintained substantially at the same level, as will be clearly seen by reference to Fig. l of the drawings. It is evident that when the upper end of the plow foot is rocked' in a rearward direction, the plow foot will at the same time be slid or .moved downwardly a suticient distance to obtain the desired result. The adjustment nose piece which is positioned therebetween, l

a plow foot comprising spaced bars having slots engaging the bolt that connects the angle braces with-the nose piece, a suitably supported lever having an arm connected with the upper end -of the plow foot, and means for securing the lever at various ad- -justments; the parts being arranged and proportioned to maintain the lower end of 'the plow foot in substantially the saine horizontal plane at various adjustments of the plow foot.

2. A plow beam having a downturned standard,l a heel plate secured thereon and having an `upturned nose piece, a bolt extending transversely throngh the nose piece, angle braces connecting said bolt with the standard, a plow foot comprising two spaced slotted bars engaging the bolt, one of said -bars being positioned on the bolt intermediate the nose piece and each angle brace with the slots sldably engaging the bolt, a rack plate secured on the plow beam, a V-shaped lever fulcrumed on the rack plate and having a short arm connected pvotally with the upper endof the plow foot adjacent to one side thereof, a brace connecting the relatively long arm of the lever with the upper end of the plow foot,said brace being Pos1- tioned adjacent to the side of the footy opposite to that engaged by the short arm of the lever, and means for retaining thelever ,9nd related parts at various adjustments.

In testimony whereof I affix my signature in presence of two witnesses.
