SAMUEL CORNELIOUS ANDERSON, OF VAN ALSTYNE, TEXAS, ASSIGNOR OF
TWO-THIRDS TO T. J. CLARK AND J. I. SOCKWELL, OF DALLAS, TEXAS.
D RAFT- EQUALIZER.
SPECIFICATION forming part of Letters Patent No. 674,252, dated May 14, 1901
Application filed October 5, 1900. Serial No. 32,143, (No model)To all whom it may concerro
Be it known that I, SAMUEL CORNELIOUS
ANDERSON, a citizen of the United States, re-
siding at Van Alstyne, in the county of Gray-
5 son and State of Texas, have invented cer-
tain new and useful Improvements in Draft-
Equalizers; and I do hereby declare the fol-
lowing to be a full, clear, and exact descrip-
tion of the invention, such as will enable oth-
io ers skilled in the art to which it appertains
to make and use the same.
My invention relates to draft-equalizers,
and has particular reference to that class of
draft-equalizers used upon plows, harrows,
15 grain-binders, and devices of alike character.
The invention consists generally of the
novel construction of the several parts and
their relative arrangement, as will be herein-
after more fully described, and particularly
20 stated in the claims.
One of the objects of the invention is to so
construct and arrange a draft-equalizer that
the draft will be equally distributed among
each of the animals attached thereto, so that
25 one may travel in the furrow, if desired, and
the remainder permitted to move over the
unplowed ground.
Another object of the invention is to cheapen
and simplify the construction of the device
30 without in any way impairing its strength or
d urability.
These and other objects are attained by
means of the mechanism illustrated in the
accompanying drawings, in which-
35 Figure 1 is a perspective view of my iun-
proved device, and Fig. 2 a bottom plan view.
In both views the letter A indicates a short
sup poi tang-tongue, which may be attached to
the forward end of a plow or other object to
4o be moved in any suitable manner.
Fulcrumed to the outer end of the sup-
porting-tongue is an angular lever B, which
has its longer arm b loosely connected to the
longer arm c of a similar angle-lever C, which
45 is also fulcrumed on the supporting-tongue.
The other or shorter arm b' of the angle-lever
B supports one end of a truss or skeleton bar
D. It may be made of wood or metal, said
truss-bar being pivoted to said arm b' by a
50 bolt E. The long arm b is also connected to
the bolt E by a link or rod F. The truss-baris centrally provided with a-cross-bar d and
is strengthened by a brace-rod d', havinggits
ends attached to the ends of the truss-bar and
its center resting in the upper end of a ver- 55
tical standard d2, secured to the central bar
cd. The free end of the truss-bar is connected
to the short arm c' of the angle-lever C by a
jointed rod G. It will be evident that a chain
may be substituted for the jointed rod. 6o
As my draft-equalizer is designed for four
horses working abreast, I attach a double
whiffletree H to the free end of the truss-bar
and a double whiffletree H' to the long arm b
of the angle-lever B. 65
From the construction and arrangement of
my improved draft-equalizer it will be appar-
ent that the animals attached thereto will
have the resistance of the load or pull equally
distributed among them. 70
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is-
1. In a draft-equalizer of the character de-
scribed the combination of the tongue or 75
buckhead of plow with the angle-levers piv-
oted thereto, the skeleton bar pivoted to one
of said angle-levers and the links connecting
said angle-levers and skeleton bar to equalize
the draft, as set forth. 8o
2. In a draft-equalizer, the combination of
the supporting-tongue or buckhead, an angle-
lever fulcrumed at the end thereof, a truss-
bar pivoted to the short arm of said angle-le-
ver, and an angle-lever fulcrumed to said 85
supporting-tongue, to the rear of the first an-
gle-bar, said levers and truss-bar being con-
nected so as to distribute the resistance of
the load among the draft-animals.
3. In a draft-equalizer,the combination with 90
the supporting-tongue, an angle-lever ful-
crumed at the end thereof, a second angle-le-
ver fulcruined back of the first and reversely
thereto of a truss-bar pivoted to the short arm
of first angle-bar, and links, substantially as 95
described, connecting the ends of said truss-
bar and angle-levers, to equalize the draft, as
set forth.
4. Ina draft-equalizer,the combination with
the supporting-tongue, of an angle-lever ful- 100
crumed at the forward end thereof, in such a
manner that the short arm thereof will ex-
