HARROW.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed. April 21, 1908. Serial No. 428.311.

To all whom it may concern:

Be it known that I, CnAnLEY Wasmxo- TON, a citizenof the United States, residing at Barboursville, in the county of Cabell and State of West Virginia, have invented certain new and useful Im movements in Harrows; and'l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same. i

This invention relates to new and useful improvements in barrows and has relation more particularly to that class known as folding harrows.

It is an object of the invention to )rovide a novel device of this character, whic 1 when being transported or stored away, can be folded in a small compass.

It is also an object of the invention to imvide a novel device of this character, wnich when in operative position will be thoroughly braced, in order that it may meet all the requirements of practice;

It is also an object of the invention toprovide a novel device of this character, wherein means are em loyed acting in conjunction with a handle t iereof for holding the foldable sections of the harrow in operative position.

It is also an object of the invention to )10- vide a novel device of this character which will be sinnle in construction, efficient in practice ttllt comparatively inexpensive to manufacture.

With the above and other objects in view, the invention consists in the details of construction and in the novel arrangement and combination of parts to be hereinafter referred to.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters of reference denote corresponding parts in the several views, and in which,

Figure 1 is a view in to tion. Fig. 2 is a sectional 'l--2, Fig. 1.

In the drawings, 1 denotes a beam, which may be of any desired length. Passing transversely through the front end portion of the beam, is a bolt 2, which is pivotally engaged by a clevis 3, which swings vertically plan of the invenview taken on hne with relation to the beam when in applied position. To this elevis is secured any suitable draft rigging. By having this cle vis ositioned as disclosed, the possibility of unt ue or unnecessary strain on the-draft animals is reduced to a minimum, said strain being caused by any undue vertical movement of the beam.

Intermediate the length of the beam 1 and secured to the sides thereof, through the medium'of the hinges 4, are the tooth beams 5, which ar adapted to be swung forwardly on the hinges and lie nearly parallel with the beam 1 in close proximity thereto. This permits theiharrow to be folded within a small compass, as is believed to be apparent.

The endsof the tooth beams 5 are beveled, so that. their movement in one direction will be so limited a to, )osition the beams 5 on a rearward incliikwiien in an operative position. In order that the strain on the lnnges 4 may be relieved, blocks 6 are secured to the beam 1 and these blocks are engaged by the beams 5, when in their operative position, as is fully shownin the drawings. The blocks 6, herein referred to are employed in conjunction withtheforwardbeams5. 'lheblocks'iacting in conjunction with the rearward beams 5, are of such configuration as to extend beneath a portion of the ends of the beams 5 and said ends of the beams 5 are soformcd as to permit such an arrangement.

Extending transversely through the beam 1 adjacent its ends, is a bolt S, which has se-\ cured thereto, on opposite sides of the beam 1, the ends of a handle 9. This handle .9 is formed preferably of a. metallic bar, bent as at 10, to form a hand grasp and havin the stems 11 terminating ,in eyes 12, to em race the bolt 8. The stems 11 intermediate their length are coiled to form eyes 13. Each of the eyes 13 has passing therethrough, the retaining eye 14 of a hook-member 15, which is adapted to engage a staple 16, or other securing means adjacent the rear end portion of the rear tooth beams 5. The staples 16 are embraced by eyes 17 of hook members 18, which engage staples 19, or other fastening means positioned adjacent the rear end por-- tions of the forward tooth beams .5. said stapics 16 and it) being arranged in a plane preferably parallel with the beam 1.

From the foregoing, it will be apparent that the tooth beams 5 are held in operative position by the handle 9. i

\Vhen it is desired to fold the barrow, it is only neces ary to release the hook members 15 and 18 from their fastening means, as is believed to be apparent.

In order to relieve the stems 11 of the handle 9 from undue strain or pressure, a reinforcing bar 20 is secured thereto, as is fully snown in the drawings. This reinforcing bar may be as desired, but it has been found best to have it terminate at both ends in eyes 21, which embrace the stems 11. It is also to be understood that the stems 11 are suitably bent, or of such an angle as to bring the hand grasp 10 in proper position. In order that the movement of the stems 11 in a downward direction may be limited, pins 22 project from opposite sides of the beam 1 and on these pins 22, rest the stems 11.

I claim: In a barrow, the combination of a beam, tooth beams pivoted thereto, a handle pivoted to the beam adjacent one end thereof,

means for limiting the movement of the hanr CHARLEY $2 WASHINGTON.
