BLAN POFF, OF TULIA, TEXAS.
DRAFT ATTACHMENT FOR CULTIVATORS.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, BLAN POFF, a citizen
of the United States, residing at Tulia, in
the county of Swisher and State of Texas,
5 have invented new and useful Improvements
in Draft Attachments for Cultivators, of
which the following is a specification.
This invention relates to draft attach-
ments for cultivators and especially for two-
10 row cultivators of the type commercially
known as the "Canton" and other culti-
vators of the same general type.
The invention has for its object to pro-
duce a draft attachment enabling four or
15 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
20 be removed from the necks of the draft ani-
mals, the draft being upward rather than
downward.
A further object of the invention is to
produce a simple and improved draft at-
25 tachment which may be readily applied to
and used in connection with the conventional
cultivator without altering the construction
of the latter.
With these and other ends in view which
80 will readily appear as the nature of the in-
vention is better understood, the same con-
sists in the improved construction and novel
arrangement and combination of parts
which will be hereinafter fully described
85 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
40 the precise structural details therein exhib-
ited, but that changes, alterations and modi-
fications within the scope of the claims may
be resorted to when desired.
In the drawings,-Figure 1 is a front ele-
45 vation of a draft attachment constructed in
accordance with the invention. Fig. 2 is a
top plan view of the same. Fig. 3 is a side
elevation. Fig. 4 is a rear elevation. Fig.
5 is a. top plan view illustrating a modifi-
50 cation. Fig. G 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.
55 Corresponding parts in the several figures
are denoted by like characters of reference.The conventional arched axle 15 is sup-
ported on the ground wheels 16. Connect-
ed with the axle by means including the
hounds or braces 17 are the thills or tongue 60
members 18. A cross bar 19 extending be-
neath the tongues is supported by means of
clips 20 that straddle the hounds.
right and left brackets 20' are mounted
adjacent to the outer faces of the tongue 65
members, the rear ends of said brackets
abutting on the axle, and said brackets be-
ing secured near their rear ends by means of
bolts 21 engaging the hound members 17.
The brackets 20' are also secured by means 70
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 24. Hook-shaped brackets 25 are 75
secured on the rear face of the axle adja-
cent to the ends thereof, said hook-shaped
brackets being curved rearwardly of the
wheels 16, and said brackets being connect-
ed by brace rods 26 with the ends of the 80
extension portions 24 of the brackets 20.
Pivotally connected with the arm 23 of each
bracket 20 is a lever B having an inwardly
extending relatively long arm 27 and an out-
wardly extending relatively short arm 28 85
with which latter an evener 29 is connected,
said evener being in the nature of a double-
tree having drop links 30 connected with the
ends thereof. Connected pivotally with the
long arm 27 of each lever B is the upper 90
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 sup-
porting the clevis 32, the two clevises 32
serving to support a cross bar 33 with which 95
a whifiletree 34 is connected. The whiffle-
tree 34 is utilized only when five draft ani-
mals walking abreast are used, when one of
the animals will be placed between the
tongues 18, a double team being hitched out- loo
side of each tongue.
Secured on each of the tongues 18 in rear
of the cross bar 19 is a yoke 35. The lower
ends of the drop links 29' are connected by
flexible elements, such as chains 36, with the 105
downwardly extending inner limbs of the
yokes 35. The downwardly extending outer
limbs of said yokes are connected by chains
37 with the lower ends of the drop links 30
it the inner ends of the doubletrees 29. 110
The drop links 30 at the outer ends of said
doubletrees are connected by chains 38 with1,099,817.
