WILLIAM H. STANSELL, OF PITTSBURG, TEXAS.
WH IFFLETREE.
SPECIFICATION forming part of Letters Patent No. 712,975, dated November 4, 1902.
Application filed May 3, 1902. Serial No, 105,802. (No model)To aUZ whom it imay concern:
Be it known that I, WILLIAM H. STANSELL,
a citizen of the United States, arid a resident
of Pittsburg, in the county of Camp and State
5 of Texas, have made a certain new and use-
ful Invention in Whiffletrees; and I declare
the following to be afull, clear, and exact de-
scription of the same, such as will enable
others skilled in the art to which it appertains
Yo to make and use the invention, reference be-
ing had to the accompanying drawings, and
to letters of reference marked thereon, which
form a part of this specification.
Figure 1 is a plan view of my invention as
15 applied. Fig. 2 is a section on the line 2 2,
Fig. 1. Fig. 3 is a section on the line 3 3,
Fig. 2.
The invention relates to doubletrees; and
it consists in the novel construction and com-
20 binations of parts, as hereinafter set forth.
In the accompanying drawings, illustrating
the invention, the letter a designates the main
bar of a doubletree provided with the plated
bearing b in its middle portion for the recep-
25 tion of a d raft-pin. To the ends of the double-
tree are also connected loops c for a chain con-
nection to the end, of a pole; but these loops,
are not rigidly attached to the doubletree-
bar. To the upper and under plane surfaces
30 of the doubletree at its ends are secured loop-
bearings d, in which play forward and back
the slides e, said slides being in pairs and
having their front and rear ends perforated
for the reception of pins or bolts, as indicated
35 at ff'. By means of the front bolts f, which
usually have threaded ends and thumb-heads,
the forward ends of the slides are connected,
and the forward loops g for the singletrees are
pivoted to said slides in such wise that they
40 can be easily removed when necessary. The
boltsf limit the backward motion of the slides.
By means of the rear bolts f' the chain-loops
c are pivoted to the rear ends of the slides.
Between the rear ends of the plates of each
45 pair of slides is located the outer loop or bar-
rel end h of a curved. plate-spring, the inner
end of which is bolted to the back of the
doubletree-bar near its middle portion. These
plate-springs extend laterally from their at-
50 tached portion toward the ends of the double-tree in opposite directions, curving somewhat
to the rear of said ends and having at their
ends the loops or barrels h, through which
the boltsf' pass, such bolts, therefore, serv-
ing to connect the rear ends of the slides to 55
the springs. These springs are designed to
be made somewhat tapering from their at-
tached portions toward their loop ends, so
that they will have an increasing tension. The
barrels of these springs limit the forward 6o
movement of the slides on the doubletree-bar.
By this device the initial shock of the draft
strain is designed to be obviated, a gradually-
increasing pressure on the shoulders of the
team being provided for by the springs and 65
slides connected to the singletrees. As the
barrels of the ends of the springs hold the
slides in direct relation to the loop-bearings
of the doubletree-bar the free motion of the
slides is not apt to be interfered with by ob- 70
lique draft strain, this being further obviated
by the. pivoted connection-loops at the ends
of the slides.
Having described .this invention, what I
claim, and desire to secure by Letters Pat- 75
ent, is-
A doubletree, having the guide-loops at its
ends, and at top and bottom, the upper and
lower pairs of slides adapted to play in said
loops, the forward pivoted connection-loops 8o
of said slides, the pivot-bolts for the same,
the rear pivoted connection or chain loops for
the slides, the singletrees having a connec-
tion with the forward loops, the leaf-springs
secured tothe doubletree,and having terminal 85
barrel connections located between the rear
ends of the slide-plates, and the pivot-bolts
connectingsaid slides,barrels and chain-loops,
the pivot-bolts for the forward loops limiting
movement of the slides and springs in one 90
direction, and the barrel connections limiting
movement of the slides and springs. in the
opposite direction, substantially as specified.
In testimony whereof I affix my signature
in presence of two witnesses.
WILLIAM H. STANSELL.
