6 Claims.

'I'his invention relates to heel sweeps and the attachment of sweep blades or turning wings thereon.

The principal object of this invention is to provide a heel sweep in the form of a single casting adapted to furnish a support for different size sweep blades and turning wings designed particularly for use therewith, the heel sweep including means to provide a rigid connection with the foot of a plow frame as well as a separable brace means for reinforcing the sides of the heel sweep.

A further object of the invention is to provide a heel sweep adapted to mount varying sizes of blades and turning wings which may be used interchangeably and each of which is adapted for individual adjustment in various positions thereon to plow shallow or deep as desired, the heel sweep including means for rigidly locking the blades or turning wings in adjusted position. This adjustment of the sweep blades or turning wings is of so simple a nature that it may be done in the eld While plowing or cultivating without the need of any special tools other than a wrench.

With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed,

it being understood that changes in the precise 2 embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:

Referring to the drawing:

Figure 1 shows in perspective a heel sweep formed in accordance with the invention and a sweep blade mounted on one of the sides thereof.

Figure 2 shows in elevation a modied form of sweep blade.

Figure 3 shows in elevation a cutter blade.

Referring to the drawing in detail, I0 denotes generally the heel sweep which is formed preferably as a unitary casting of malleable iron or steel and comprises a bight portion II and a pair of diverging side walls I2 and I3, the whole being in effect a V-shaped standard. The bight portion II constitutes the forward portion of the heel sweep I0 and is substantially rectangular in form, being arranged to lie in a plane inclined downwardly and forwardly with reference to the ground engaging surface (not shown). In other words the upper transverse edge I4 of the bight portion II lies in a, vertical plane to the rear of the lower transverse edge I5. Formed integral with the bight portion II is a square lug I8 projecting normally from the surface of the bight portion, said lug I6 being disposed adjacent the upper transverse edge I4 substantially midway between the side edges of said bight portion. In line with the square lug I6 and between the same and the lower transverse edge I5, there is provided in the bight portion II, a, square hole I1, the square lug I6 is adapted to extend through a complemental opening provided therefore in the plow foot (not shown) .to prevent turning movements of the heel sweep thereon, the heel sweep III being rigidly secured to said plow foot by a bolt (not shown) of 'the kind provided with a square shank adjacent the head thereof which bolt is adapted to extend through the opening Il.

Extending rearwardly Iin diverging relation from the bight portion II of the heel sweep and integral therewith are the side walls I2 and I3. Preferably the side Walls I2 and I3 each taper in thickness from the top edge I8 thereof to the bottom edge I9. Each of the side walls I2 an I3 lie in a plane inclined in a downwardly and outwardly direction with reference to a vertical center plane intersecting the bight portion II.

Formed in each of the side walls I2 and I3 are a pair of spaced elongated slots 20 and 2l extending lengthwise of the respective side wall. The outer slot 20 is positioned adjacent the upper edge I8 andthe terminal edge 22 of each side wall, while the inner slot 2l is positioned inwardly with respect to the outer slot 2| and adjacent the lower edge I9 and bight portion II.

A brace 24 comprising a bar portion 25 provided at each end with a flattened ear, 26 and 21, extends between the side walls I2 and' I3 with the

ears

26 and 21 adapted to respectively con'- tact the inside surfaces of said side walls. Each ear, 26 and 21, carries a bolt 28 provided with a countersunk head 29 which bolts extend through the slots 20 for a purpose to be hereinafter described. Adapted for use with the heel sweep I0 are the sweep blades or turning wings 30 (Fig. 1) and 3| (Fig. 2), and scrape blade 32 i Fig. 3). Each blade is particularly adapted for a specific use as is` well known in the art. The blades 30, 3| and 32 are-formed in pairs, that is, a pair of bladesA of the form such as 30 f Fig. 1) comprises a left hand blade 30 for mounting on the heel sweep side wall I3, and a complemental right hand blade 30 for mounting on the side wall I2, as shown in Fig. l. Thus, this invention contemplates not only the use of such blades in like complemental pairs, but also the mounting on the heel sweep of a left hand blade of one pair and a, right hand blade of another pair, as for example, with the right hand blade 30, Fig. 1. There may be used if so desired, a left hand blade 3| or a left hand blade 32. To permit such an interchangeable use of the several blades each blade is provided with a countersunk hole 33 and a vertical arcuate slot 34, the slot 34 dening an arc of a circle about the center of the hole 33 as a center. On each of the blades 30, 3| and 32 the relationship of the hole 33 and slot 34 is identical, which relationship is dependentl on the relationship of the slots 20 and 2| in the heel sweep side walls I2 and I3, such that when a blade is positioned on a side wall, the bolt receiving countersunk opening 33 will register with the slot 2|), while the arcuate slot 34 will register in cross-wise relation to the slot 2|.

Referring to Fig. 1 it will be seen that the sweep blade 30 is attached to the side wall I2 by means of the bolt 28, the countersunk head thereof seating in the countersunk opening 33, and a bolt 35 which extends through the slots 34 and 2|. The bolts 28 serve to clamp the brace 24 and the blades securely to the side walls, thus providing along with the bolts 35 an exceedingly rigid interconnection between the blades, heel sweep and brace. By virtue of the side wall slots and 2|, the blades may be adjusted lengthwise of the side walls |2 and I3 within the limits of said slots. Also with the bolt 28 as a pivot each blade may be angularly adjusted within the limits of the arcuate slot 34.

Thus the character of the work which the heel sweep l0 will do may be varied at will.
