F. L. ASHENHURST mmnow unc'mmn'r FOR nous ru a Aug. 9. 192a 2 Quota-Shut 2 Inventor FL.A shen/7z u's Attorngy v Patented Sept. 16, 1930 UNITED STATES FRED L. ASHENHU'RST, or LINGLE, WLYOMING H'ARROW ATTACHMENT Ton rLows Application filed August 9, 1928. Serial No. 298,528.

- The present invention relates to means by which a relatively small harrow section may be attached to a conventional plow.

An important object of the invention resides in the provision of a device of this nature which is exceedingly simple in i'tsconstruction, strong and durable, inexpensive to manufacture, thoroughly efficient and reliable in use and otherwise well adapted to the purpose for which it is designed.

l/Vith the above and numerous other objects in View as will appear as the description proceeds, the'invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of the device embodying the features of my invention,

Figure 2 is a perspective View of the bracket beam, I

Figure 3 is a top plan view of the attachment,

' Figure 4 is a rear end view of the bracket beam, v

Figure 5 is a transverse section through an intermediate portion of the bracket, and

Figure 6 is an enlarged detail view showing one end of the bracketbealn attachedto the plow beam.

Referring to the drawings in detail, it will be seen that the numeral 5 denotes a conventional plow beam with a plow 6 mounted thereon.

The numeral 7 denotes generally a well known form of harrow. The numeral 8 denotes a bracket beam with a lateral oblique extension 9 at one end. v This extension 9 is at the front end and terminates in a down wardly oflset arm 10 which is secured to the beam 5 as is indicated at 11 by suitable means so that the bracket beam extends rearwardly therefrom.

At the rear end the bracketbeam 8 is in spaced parallelism with the plow beam 5 and is provided with a pair of downwardly and si'dewardly inclined arms 12 which diverge. downwardly from each other. An arm 14 is secured to the front end of the bracket beam of the harrow 7'.

- unit is raised;

An inverted Ushaped member 15 has its apex fixed as at 16 to an intermediate portion of the bracket beam 8 and depends therefrom. The legs of the memberl5are disposed in a plane parallel with thearms 12, but areof lesslength than the arms. Chains 16 are secured to the lower end of the arm 14 andto clevises 17 on the front end ofthe side member of the harrow 7.

Chains 19 are secured to the extremities of the arms 12 andnto rear portions ofthe sides The entire assembly when attached to the plow as just described'permits the drawing of theharrow section through the: field directly in rear of and parallel to the plow.

It provides further for the simultaneous raising of the'plow structure when the plowing Theobject of theinventi'on resides in the accomplishment of the harrowing of the. soil in conjunction with and at the same operation of plowing of the soil. i

This results in the saving of time i. and accomplishes the harrowing of the soil as soon after plowing as is possible which results in 'a'betterharrowingbecause of the i very freshness of the soil itself.

It is thought that the construction, utility and advantages of the invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in detail merely for the purposes of exemplification' since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I. claim as new is:

10 and depends therefrom in a vertical plane. 1. In combination, a plow, a plow beam on the plow, a harrow, a bracket beam having at its forward end an obliquely disposed extension secured to the plow beam a rigid arm depending from the forward end of the bracket beam, a pair of rigid arms depending from the rear end of the bracket beam and diverging downwardly from each other, an inverted U-shaped member secured to the intermediate portion of the bracket beam, to V depend downwardly therefrom, chains at the extremities of the arms and" secured to the harrow.

2. In combination, a plow, a plow beam on the plow, a harrow, a bracket beam having on its forward end an obliquely disposed extension secured to the plowv beam above the plow and at its rear end in spaced parallelism withthe plow beam, a rigid arm de-- pending from'the point of juncture between the ofiset and parallel portions of the bracket beam, a pair of. V-shaped rigid brackets secured to the parallel portion of the bracket beam having the legs thereof disposed in the same plane of inclination, chains secured at the extremities of the arms and at the extremities of the legs ofzthe brackets and to the harrow. t

3. In combination, a plow, a plow beam on the plow, a harrow, a bracket beam having on its forward end an obliquely disposed eX- tension secured to the plow beam above the plow and at its, rear end in spaced parallelism with the plow beam, a rigid arm depending from the point of juncturebetween the offset and parallel portions of the bracket beam, a pair of V-shaped rigid brackets secured to the parallel portion of the bracket beam having the legs thereof disposedin the same plane ofinclination, chains secured at the extremities of the arms and at theextremities of the legs of the brackets and to the harrow, the legs of the forwardly disposed V-s'ha'ped vbracket of less length than the rearwardly disposed V-shaped bracket.

In testimony whereof I aflix my signature.
