WHiFFLETREE-COUPLING.
EPECIFICATION forming part of Letters Patent NO. 320,313, dated June 161 1885.
Application ?led April 13, 1885. (X0 model.)
T0 aZZ whom it may concern:
Be it known that I, \VILLLUI S. \VARD,
of Plantsville, in the county of Hartford and
State of Connecticut, have invented certain
5 new Improvements in \Vhi?lctree-Couplings;
and I do hereby declare the following, when
taken in connection with accompanying draw
ings, and the letters of reference marked there
on, to be a full, clear, and exact description of,
Fig. 2.
In the whi?'letrce, above the opening
in the plate, a recess, Z, is ‘formed.
F is the whit'lletreebolt.
'
This bolt has a
head, m, and its neck n is of angular shape, 55
corresponding to the angular opening a in the
socket.
It is introduced through the plate E _
before the plate E is fixed to the whi?ietree,
with its head in the recess Z in the whi?'letree,
and as seen in Fig. 2. An opening is made 60
10 the same, and which said drawings constitute through the whi?'letree-bar corresponding to
part of this speci?cation, and represent, inA the opening in the socket, and through which
. Figure l, a rear view of the whii’?etree bar
the bolt extends.
The lower end of the bolt
and plate, showing the coupling; Fig. 2, a is screw-threaded, and upon this screw-thread
vertical central section through the coupling, a nut, G, is applied. From the plate E ahook 65

method of applying the whil’tletree to the bar.
This invention relates to the device by
which a whif?etree is coupled to the whii?e
will engage with the ?ange D of the socket, as
seen in‘ Fig. 2.
The whiftletrce is applied by turning it to
treebar of a carriage, the object being the nearly right angles to the whil’lletree-bar, and
construction of the coupling so that the whif~
?etree may be readily detached or applied as
25 occasion may require, and at the same time
form an easy but anti-rattlingjoint upon which
the whi'f?etree may play; and the invention
consists in the construction, as hereinafter de
scribed, and more particularly recited in the
30 claims.
A represents the whil‘?etree, B the whil?e
tree-bar.
On the whif?etreebar the socket C is so‘
cured. This socket is a plate of metal hav
so that the hooked projection H may pass
down to one side of the socket. Then when 75
the hooked portion has arrived into the plane
of the ?ange D the whi?'letree is turned to take
the hook portion H into engagement with the
?ange D.
The extent of the ?ange D is sufficient to 80
prevent the ordinary working ol'the whil?etrec
from taking the hook out of engagement with
the ?ange. The ?anged on the socket, there
fore, forms a central bearing on which the whif
?etree may oscillate, while the ?ange D pre
35 ing a central, preferably angular, opening, a, vents the whi?letree from being lifted from its
through it, and surrounding this opening a is position on the socket. At the same time the

A ?ange, (1, around the central bolt F draws the whillletree down upon the
opening, extends above the upper plane of the spring in the socket with su?icient force to
