Improvements in Thill-couplings.
I, ACHILLES STEVENS, of Newport, in the County of Newport, and State of
Rhode Island, Inventor, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to thill-couplings; the object of the invention being to
provide a simple, yet strong device of the kind.
The invention comprises an axle-clip having a pair of projecting spaced ears.
A finger extends over each ear in such manner as to form a groove between its
underside and the circular contour of the ear.
The thill-iron, which is mounted on a pin, fits between the ears, and has lugs
which extend on opposite sides of the iron and fit into the respective slots where
they are retained by the fingers.

I, ACHILLES STEVENS, of Newport, in the County of Newport and State of
Rhode Island, U.S.A., Inventor, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:―
This invention relates to that class of thill coupling which enables the thills to
be thrown back when out of use and to be readily detached when desired, for repair
or other purposes..
The object of the invention is to provide a device of the kind aforementioned
which will be of simple through strong and durable construction.
Reference being had to the drawings;-
Fig. 1 is a perspective view of my improved coupling secured in position to the
bolster and axle.
Fig. 2 is a central vertical section taken through the coupling, bolster, axle,
thill-iron and one of the thills.
Fig. 3, is a vertical section taken on the line of Fig. 2.
Fig. 4, is an end view of the coupling, the bolster and axle being in section,
and the coupling partly broken away to illustrate the manner of detaching the
thill-iron and thill.
My improved coupling comprises the usual clip 1 by means of which the body 2

page_text: of the coupling is secured to the bolster and axle in the way well known in con-
nection with this class of coupling.
The body 2 is bifurcated to form ears which are perforated to receive a bolt 4,
and which are also formed with overhanging fingers 5 forming curved openings 6.
The rounded inner end or head of the thill-iron 7 has a transverse perforation,
in which is fitted a leather or like packing 8, and a transverse slot 3. A bar 10
is secured to the upper portion of the head of the thill-iron, and has lugs 11 which
project into and travel in the openings 6 when the thills rise or fall.
The thill-iron is placed over the bolt when held in the position shewn in Fig. 4,
and will be retained thereon, when raised, by reason of the lugs 11 engaging
beneath the fingers 5. When out of use, the shaft can be raised into a substan-
tially vertical position; the backward inclination thereof being limited by the
lugs 11 coming into contact with the extreme inner ends of the openings 6.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed; I declare that what
I claim is
The hereindescribed thill-coupling comprising a body portion suitably attached
to the bolster and axle of a vehicle, bifurcated to form forwardly projecting trans-
versely perforated ears, and having forwardly projecting curved fingers extending
over said ears, a bolt adjusted through the perforations in said ears, and the thill-
iron having its inner rounded head transversely perforated to seat a leather or
suitable packing and a transverse groove enabling said head to be placed in posi-
tion over the aforesaid bolt, and the projecting lugs on said head for preventing
displacement thereof when in use, all substantially as and. for the purposes
described, and as illustrated in the drawings hereunto annexed.
