DRAFT ATTACHMENT FOR CULTIVATOES.

Specification of Letters Patent.

Patented June 9, 1914 Application filed November 18, 1913. Serial No. 801,704.

To all whom it may concern:

Be it known that I, ELAN Porn, a citizen of the United States, residing at Tulia, in the county of Swisher and State of Texas, have invented new and useful Improvements in Draft Attachments for Cultivators, of which the following is a specification.

This invention relates to draft attachments for cultivators and especially for tworow cultivators of the type commercially known as the Canton and other cultivators of the same general type.

The invention has for its object to pro duce a draft attachment enabling four or five horses to be used, and including eveners whereby the draft will be equalized.

A further object of the invention is to produce a construction including a drop hitch whereby the weight of the tongue will be removed from the necks of the draft animals, the draft being upward rather than downward.

A further object of the invention is to produce a simple and improved draft attachment Which may be readily appliedto and used in connection with the conventional cultivator without altering the construction of the latter.

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

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,-I igure 1 is a front elevation of a draft attachment constructed in accordance with the invention. Fig. 2 i a f I of the cross bar 19 is a yoke 35. ends of the drop links 29 are connected by top plan view of the same. Fig. 3 is a side elevation. Fig. 4 is a rear elevation. Fig. 5 is av top plan View illustrating a modification. Fig. 6 is a perspective detail view of one of the hitching brackets and related parts. Fig. 7 is a perspective detail view of the drop link and the clevis carried thereby.

Corresponding parts in the several figures are denoted by like characters of reference.

The conventional arched axle 15 is supported on the ground Wheels 16. Connected wlth the axle by means including the hounds 0r braces 17 are the thills or tongue members 18. A cross bar 19 extending beneath the tongues is supported by means of clips 20 that straddle the hounds.

flight and left brackets 20 are mounted adJa n to the outer faces of the tongue members, the rear ends of said brackets abutting on the axle, and said brackets being secured near their rear ends by means of bolts 21 engaging the hound members 17. The brackets 20 are also secured by means of clips 22 engaging the cross bar 19, and

said brackets include arms 23 that extend laterally and outwardly from the forward ends thereof, said arms having rearward extensions 2e. Hook-shaped brackets 25 are secured on the rear face of the axle adiacent to the ends thereof, said hook-shaped brackets being curved rearwardly of the wheels 16, and said brackets being connected by brace rods 26 with the ends of the extension portions 24 of the brackets 20.

Pivotally connected with the arm 23 of each bracket 20 is a lever 13 having an inwardly extending relatively long arm 27 and an outwardly extending relatively short arm 28 with which latter an evener 29 is connected, J said evener being in the nature of a doubletree having drop links 30 comiected with the ends thereof. Connected pivotally with the long arm 27 of each lever B is the upper end of a drop link 29". The drop links '29 are each provided with a series of aper tures 30' for the passage of a bolt 31 supporting the clevis 32, the two clevises 32 serving to support a cross bar 33 with which a whitlietree is connected. The whiffletree 34 is utilized only when five draft animals walking abreast are used, when one of the animals will be placed between the tongues 18, a double team being hitched outside of each tongue.

Secured oneach of the tongues 18 in rear The lower flexible elements, such as chains 36, with the downwardly extending inner limbs of the at the inner ends of the doubletrees 29.

The drop links 30 at the outer ends of said doubletrees are connected by chain 38 with tioned to take into account the fact that the one animal walking between the tongues has to pull against the four animals walking outside of the tongues. When it is desired to use only four draft animals, the one walking in the middle is dispensed with, and the inner ends of the inwardly extending long arms 27 of the levers B are connected together by arigid brace member 41 secured thereon by means of bolts 42, as seen in Fig. 5. A similar brace member 41 may be used to connect together the inner ends of the yokes 35, or said inner ends may be secured in any convenient manner so that the stay chains 37 wvill be effective when the middle swingletree is dispensed with, as in Fig. 5. The levers B, B will thus be converted into what practically constitutes a single rigid cross bar with the ends of which the doubletrees 29 are connected. The peculiarly constructed brackets 20 and yoke 35 permit the useof the drop links 30 and 29, the lower ends of which are connected with the downwardly projecting stubs 39 of the brackets and with the downwardly extending limbs of the yokes, by means of flexible elements, such as chains, whereby the draft is properly transmitted in such a manner that an upward rather than a downward strain will be exerted, and the necks of the draft animals will be relieved of undue weight.

' The general construction of the improved attachment is simple and inexpensive, and it is of such a nature that it may be readily applied to two row cultivators of conventional construction, the arrangement being such that the plants will be cleared by the attachment and that the draft animals will be placed between the rows of plants.

Having thus described the invention, what is claimed as new, is

1. The combination with a two-row cultivator having an arched axle, and tongues provided with hounds connected with said axle, of brackets abutting on the axle and secured on the hounds near their rear ends, a cross bar supported by the hounds and supporting the brackets near their front ends,

i said brackets including lateral arms having rearward extensions provided with terminal downwardly projecting stubs, and draft means including eveners having drop links, yokes secured on the tongues and having downwardly extending limbs, flexible elements connecting the drop links with the yokes and with the stubs of the brackets, and swingletrees connected with the drop links.

2. A draft attachment for two-row cultivators comprising brackets having lateral arms with rearward extensions provided with downwardly projecting stubs, means for supporting said brackets adjacent the cultivator tongues with their rear ends abutting on the axle, yokes straddling the tongues, levers fulcrumed on the lateral arms of the brackets, drop links connected with the inwardly extending long arms of the levers, chains connecting the lower ends of the drop links with the inner limbs of the yokes, a cross bar connecting the drop links and having a whiffletree, eveners connected with the outwardly extending short arms of the lovers, drop links at the ends of the eveners, chains connecting the lower ends of the drop links at the inner ends of the eveners with the outer limbs of the yokes, chains connecting the lower ends of the drop links at the outer ends of the eveners with the depending stubs of the brackets, and whiflletrees connected with the drop links at the ends of the eveners.

3. The combination with a two-row cultivator having an arched axle and tongues, of

a draft attachment comprising forwardly extending brackets abutting on the axle and including lateral arms having rearward extensions provided with downwardly projecting stubs, hook-shaped brackets secured on the rear side of the axle, means for supporting the first mentioned brackets including a cross bar extending beneath the tongue, braces connecting the hook-shaped brackets with the rearward extensions of the forwardly extending brackets, yokes straddling the tongues, levers fulcrumed on Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
