An Improved Railway Vehicle Coupling.
We, CHARLES HENRY WORNER RELYEA, Mechanic of North Adams, JOHN
ROBERT SUTTON, Attorney-at-Law, of Hillsdale and BURR WILBUR, Travelling
Salesman, of Hillsdale, all in the County of Hillsdale, Michigan, U.S.A., do
hereby declare the nature of this invention to be as follows:-
•
:-
In the coupling of this invention the outer end of the drawhead is bifurcated and
consists of an upper and a lower plate. In the inner face of each plate there is a
recess. A jaw is pivotally mounted between the two plates and has an enlarged
head projecting beyond the plates. It has also a pair of lugs which work in the
recesses in the plates so as to permit to a limited extent an angular motion of the
jaw. The jaw is provided with a transverse arm which is engaged by the jaw of
the opposite coupling part when two vehicles are pushed together. The rear end
of the jaw has an inclined slot in which the end of a lever pivotted on one of the
plates is operated by lever mechanism to engage and disengage the jaw. The
front end of the jaw is provided with a pair of laterally extending lugs which have
link pin holes to receive the ordinary link pin.

An Improved Railway Vehicle Coupling.
We, CHARLES HENRY WORNER RELYEA, Mechanic of North Adams, JOHN
ROBERT SUTTON, Attorney-at-Law of Hillsdale, and BURR WILBUR, Travelling
Salesman, of Hillsdale, all in the County of Hillsdale, Michigan, U.S.A., 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 :-
In the drawing Fig. 1 is a plan of two coupling parts constructed in accordance
with this invention. Fig. 2 a side view of one of the coupling parts. Fig. 3 a front
view of the same. Fig. 4 a longitudinal vertical section. Fig. 5 a horizontal
section.
A is a drawhead having a forked or bifurcated front consisting of a top plate a
and a bottom plate a', these plates being preferably in one piece with the drawhead.
In the inner face of each plate is formed a recess a². a³ is a pin hole in each
plate near the end of each recess the pin holes registering with each other. The
top plate is provided near the end of the drawhead with a longitudinal slot a' and
in the bottom plate directly below this slot is formed a recess a³, sloping at its
bottom, being deepest at its front end. a is a pair of ears attached to the upper
part of the top plate, one on each side of the slot at, each ear having a bolt hole a'.
The front end of each plate is rounded off as at a³.
A jaw B is pivotally mounted between the top and bottom plates and has an
enlarged head b projecting beyond the plates. This jaw is formed with

page_text: concavities b' to fit against the rounded parts as of the plates. 63 are two lugs on
the jaw which fit in the recesses a² in the plates so as to permit a limited amount of
angular motion of the jaw. is a bolt hole in the jaw registering with the pin or
bolt holes a³ in the plates and through all of which is passed the pivotal bolt C
arranged to be in the longitudinal central vertical plane of the drawhead so that all
lateral strains may be avoided. The jaw is provided with a transverse arm 6°
engaged by the jaw of the opposite coupling part in coupling together two vehicles,
and is forced backward thereby swinging its own jaw into engagement with the
jaw of the opposite coupling part. The transverse arm normally rests against
shoulder a upon the top and bottom plates the shoulder receiving the impact of the
opposite coupling part. The front end of the jaw has a pair of laterally extending
lugs & having link pin holes to receive the ordinary link pin when necessary to
couple a carriage provided with a coupling part of this invention to an ordinary
link pin coupling part. The back end of the jaw has a rearward and laterally
extending spur 8 and diagonal slot bº.
a
In the ears a is pivotted a coupling pin D having two arms at an obtuse angle
to one another, a bolt E passing through the holes a' and serving as a fulcrum.
The short arm of the coupling pin D normally rests upon the upper surface of
the top plate a. It is weighted at its forward end and has a lug d³ with a hole d'.
The long arm d³ of the coupling pin or lever D passes through the slot a¹ and
normally rests with its lower end in the shallowest part of the recess a³, said long
arm being adapted to swing forward when the weighted end of the short arm is
raised and when thus swinging forward to engage the diagonal slot 6' in the jaw B
and thus press the inner end of the jaw to one side thereby swinging the front end
of the jaw in the opposite direction and serving to move the jaw into its uncoupled
position. In order that the long arm of the pia D may move with less friction in
the diagonal slot it has its corners bevelled as at dº, d², d³.
a
In order to raise the front end of the short arm of the pin D and thereby
uncouple the jaw from any opposite one with which it may be engaged an operating
shaft is provided mounted in bearings f fixed on the vehicle, and having
cranked outer end" and an inner end 2 cranked at right angles to the outer end,
the latter cranked end being attached by a link G to the lug of the pin D in any
suitable manner.
The operation of the coupling is obvious from the above description.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a coupling for railway vehicles the combination of a draw head having its
extremity bifurcated whereby a top plate and a bottom plate are formed, the said
top plate and bottom plate provided with registering pin holes and recesses a²
extending radially from said pin holes, the jaw B pivotted at said pin holes and
provided on opposite sides with projections or lugs of less width than, and arranged
in the recesses in, the adjacent faces of said plates, said jaw having a lateral lug at
its forward end and a transverse arm engaging when in its locked position some
fixed part of the drawhead, the rear end of the jaw being provided with an inclined
slot, and an uncoupling pin or lever D pivotted in the draw bead behind the rear
end of the jaw and in position to engage the inclined slot therein said pin or lever
having its upper end weighted and bent forward, substantially as described and
shewn.
