WHEELED HARROW.

SPECIFICATION formingpart of Letters Patent No. 574,102, dated December 29, 1896.

Application filed April 11, 1896. Serial No. 587,090. lNo model.)

To all whom it may concern: 1

Be it known that I, DAVID C. MILLER, acitizen of the United States, residing at Cedarville,in the county of Smith and State of Kansas, have invented certain new and useful Improvements in Wheeled Harrows; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a barrow, and particularly to a. wheeled harrow, and its novelty will be fully understood from the following description and claims when taken in connection with the annexed drawings.

The object of the invention is to provide a wheeled or sulky harrow having a seat for the operator and an improved means whereby the wheels and their axles are automatically turned or directed to follow the draft or course of the harrow.

A further object of the invention is to provide a novel and peculiar hound and an automatic means operating in connection with the hound to fix the latter with the harrowbeams and to disconnect it from said beams to compel the sulky to follow the course of the harrow.

Further objects and advantages peculiar to this machine and accruingfrom its novel c011- struction will be hereinafter disclosed.

The invention consists in the novel construction and arrangement of parts, as will .be hereinafter fully described, and set up in the claims.

In the accompanying drawings, forming part of this application, Figure 1 is a top plan view. Fig. 2 is a section on the line 00 0c of Fig. 1 with parts broken away and seat removed. Fig. 3 is an enlarged plan view of the hound. Fig. 4 is an enlarged elevation of the automatic attachment which comprises the foot-bar, its bolt, and spiral spring. Fig. 5 is a front edge View of a modified form of hound.

The same numeral references denote the same parts throughout the several figures of the drawings.

The harrow, which is intended to precede the sulky, is of ordinary construction, having a front swing-bar 1, to which is attached a doubletree, and from which the main harrowbeams 2 extend in the ordinary V-shaped form to a point where they are housed by a clevis 3 and secured to the sulky-axle 4c. The said point of the beams 2 is held in the clevis 3 by a bolt 5, passing through the latter and through top and bottom plates 6 and 7 respectively, secured to the said beam ends 2. Thus the harrow and the sulky are pivoted together by thebolt 5, and the harrow-beams have bracerods 5.

Between and near the pivoted ends of the harrow-beams2 is tenanted therein a plat form 5, leaving a space 9 between said platform and the pivoted ends of the beams 2.

Opposite the platform 8 is secured to the under side of the beams 2 the hanger'guides 9 for the hound 10, the ends of the latter being secured to the axle 4 near the wheels 11. This hound is provided cent-rally with two inclined lugs 12 and aninterveningnotchl3, and upon each side of these lugs 12, toward the ends of the hound, is formed similar inclined lugs 14. The hangers are large enough to allow free passage of the lugs 12 and 14 as the harrow and sulky are turned upon the point 5.

The automatic device for holding the hound fixed with the harrow-beams 2 consists of the foot-lever l5, hinged or pivoted at 16 to the under side of the platform 8, so' as to swing vertically. The lever has an offset or notch 17, and when the harrow and sulky are fixed together this offset 17 engages the notch 13 of the harrow and prevents the harrow or sulky from swinging on the pivot 5. The free end of the lever is provided with a foot-rest 18, which is operated through the opening 9 to disengage the lever with the hound and allow the latter to slide through the guide-hangers 9, in accordance with the course of the harrow,said hound being stopped from unnecessaryor too free movement to the right or left by the lugs 14, which engage the lever 17, while the latter-is held in engagement with the hound by the spiral spring 19. This spring is located on top of the platform and surrounds the guide-bolt 20 of the lever 15, said bolt being operated through the slot 21 in the platform 8.

It will be observed that the spring holds the lever in normal position, and the latter has only to be pushed downward until the notches 17 and 13 are disengaged, when the YCO pressure is released, and the lever will. automatically be returned by the spring 19 and kept in engagement with the hound, as and for the purpose hereinbefore described.

Referring to the modification shown in lii g. 5, the hound 22 has a central notch 23 and depending shoulders instead of lugs 12 and tion by the driver to the sulky, harrow, or i any other part of the machine.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with aharrow, a sulky to which it is pivoted, a hound having lugs and an intervening notch,an automatic in cans l l I for fixing the hound to the sulky comprising the foot-lever pivoted at one'end to the l1ar row-platform, a guide-bolt secured to the lever and working through the platform, and a spiral spring between the bolt-head and the platform, substantially as set forth.

2. The combination with a harrow having supporting-beams, a platform at the intersection of the rear ends of said beams, a sulky pivoted to said ends, a hound immovably secured to the snlky-axle and operated in guidehangers secured to the said beams, a foot-lever pivoted to the platform, a bolt secured to the lever and extending through the platform and a spiral spring around the bolt upon the platform adapted to eontrolthe movementof the lever, as set forth.

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