PROVISIONAL SPECIFICATION.
An Improved Car-coupling.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Amos Fisk, and William Cole, both of Lake
Crystal, Minnesota, U.S.A. Inventor.) to be as follows:-
This invention has reference to an improved car-coupling, and the object of the
invention is to provide means whereby railway cars will be automatically coupled
when run together. The invention comprises a draw-head which consists of a
hollow cylindrical piece of metal which is secured beneath the car in such manner
that it projects beyond the end thereof. The mouth of the draw-head is bevelled
in such manner as to cause a link projecting from an adjacent draw-head to readily
enter the same. Within a short distance from the mouth of the draw-head its
upper portion is cut away, in such manner, as to expose the hollow interior.
Near the mouth of the draw-head is pivoted an hook-shaped piece of metal in
such manner that its hook projects downwardly, and engages a depression or slot
formed in the under side of the draw-head. This piece of metal is provided with
a shank which projects rearwardly, and is weighted, for the purpose of keeping the
hook-shaped piece of metal within the depression made for its reception when the
weight is in its normal position, that being when it falls into the hollow rear
portion of the draw-head."
It will be understood that when a link is brought into contact with the hook-
shaped piece of metal the hook is raised, and its weight elevated by the concussion.
Directly the link has passed the hook the weight will fall into place, and the link
be securely retained behind it. In order to disengage the link the weight is
raised, which allows the link to clear the hook and be withdrawn.
Dated this 3rd day of January 1891.

An Improved Car-coupling.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
ondon, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Amos Fisk, and William Cole, both of Lake
Crystal, Minnesota, U.S.A. Inventors), 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 car-couplings, and more especially to that class known
as "hook and link" and the object of the same is to effect improvements upon
car-couplings of this same general character heretofore existing.
To this end the invention consists of the specific detail of construction herein-
after more fully described and illustrated in the accompanying drawings, in
which-
Fig. 1 is a central longitudinal section of my improved draw-head, showing the
link as engaged therein. Fig. 2 is a plan view. Fig. 3 is a perspective view of a
freight-car provided with my improvement.
Referring to the said drawings, the draw-head A. has a longitudinal slot a on top
to receive the locking-dog B which is mounted on a pivot b through the draw-head

in front of said slot, and which has lateral shoulders S abutting against the
curved rear corners R of the draw-head, as shown in Fig. 3. In rear of said
pivot a broad weighted block W is integrally connected with the dog B which
covers the slot a and prevents the access of water or dirt thereto. The forward
end of the dog B turns upwardly, as at U, within the flaring mouth of the draw-
head A, whereby a link C, on entering the draw-head, will be guided beneath the
dog. Upon the lower side of the dog about opposite the pivot b is a hook H
adapted to pass downwardly into a cavity V in the bottom of the draw-head and
to engage the link C, as shown in Fig. 1. When so engaged a tension upon the
link draws the shoulders S against the rear faces R, thereby relieving the strain
upon the pivot-bolt b, the opening therefor in the sides of the draw-head being
elongated, as shown in dotted lines in Fig. 1. On the under side of the dog in the
rear of the hook H is secured a spring D whose free end stands adjacent said
hook and rests normally upon the inner end of the link C, as shown in Fig. 1. By
this means the link is sustained in proper position, and will be caused to enter a
companion draw-head, as will be readily understood. To the inner end of the
block is connected a chain F which may lead through an eye gl at the top of the
car, to uncouple the cars from that point, and a lever H' may be pivoted, as at h to
the end of the car, one end being connected to the chain F, and the other end
extending to one side of the car, whereby the cars may be uncoupled from that
point.
This car-coupling is very simple in construction efficient in operation, and
durable in use, and all longitudinal strain upon the pivot-bolt b is relieved by the
shoulders S. The link may swing from side to side, as shown in Fig. 2, and may
rise and fall, as shown in dotted lines in Fig. 1, but the weight of the weight-
block W is sufficient to prevent its disengagement from the hook H.
Having now particularly described and ascertained the nature of this my
said invention, and in what manner the same is to be performed, I declare that
what I claim is:
1. In a car-coupling, the combination, with the dog B having a downwardly
extending hook H near its front end, and lateral shoulders S in rear of said hook,
and the bolt passing through said dog above the hook, of the draw-head A within
which the said dog fits loosely, said draw-head having a longitudinal slot a in its
upper side, rearwardly facing shoulders R at each side and opposite the forward
end of said slot, adapted to engage said lateral shoulders, and longitudinal slots in
its sides in which said bolts are pivoted, the whole operating substantially as
described.
2. In a car-coupling, the combination, with the dog B, having the downwardly
extending hook H near its front end, a weight-block W at its rear end, and a
spring D connected to the lower face of said dog, with its free end extending
adjacent to said hook, of the draw-head A within which said dog is pivoted at a point
above said hook, said draw-head having a cavity V in its lower face by which to
receive the top of said hook, the whole operating substantially as described.
3. In a car-coupling, the combination, with the draw-head A, provided with a
longitudinal slot a in its upper side, and with a cavity V in its lower side forward of
said slot, of the dog B pivoted near its front end on a horizontal bolt through
said draw-head, a hook H projecting downwardly from said dogs beneath its pivot
into said cavity, and a weight-block W carried by the rear end of the dog above
said slot of the same width as the draw-head, the whole operating substantially as
and for the purpose set forth.
