We, JAMES PENELTON, of Carden Street, in the City of Guelph, in the County
of Wellington, and Province of Ontario, Canada, Merchant, GEORGE SLEEMAN,
of Waterloo Avenue, in the said City of Guelph Brewer, and JOHN MCHARDY, of
Gordon Street, of the same place, Merchant, 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 :-
The object of the invention is to provide a car coupler which is simple and
effective in construction and which locks automatically when the cars come together.
and it consists, essentially, of a double-headed pin with flattened oblong heads and
a weighted rod attached substantially midway between the heads and in a plane
parallel to the flat surfaces of the heads, and draw-heads each provided with a
locking chamber with openings oblong in section leading thereto, and adapted to
receive the oblong heads when their flat surfaces are horizontal, so that when the
cars come together both oblong heads enter their respective locking chambers so as
to be free to move and make a quarter revolution by reason of the weighted rod,.
the flat surfaces of the oblong heads thus assuming a vertical position so as to
lock against the walls of the locking chambers, substantially as hereinafter described
and specified.
Figure 1, is a perspective view showing the device in position on the end of a car
ready to couple with another car.
Figure 2, is an enlarged perspective detail partly broken away showing one of
the oblong heads of the device within the locking chamber of a draw-head of a car
to be coupled and before the oblong head on the other end of the pin has been
moved into its locking chamber, the flat surfaces of both heads being horizontal.
Figure 3, is a longitudinal sectional view through the draw-heads showing the
cars coupled, the oblong heads having entered their respective locking chambers:
and their flat surfaces having assumed a vertical position by the action of the
weighted rod which has fallen to a vertical position so as to lock the heads within
their respective chambers.
In the drawings, like letters of reference indicate corresponding parts in the
different figures.
In Fig. 1, A, is a body of a car provided with draw-head B, with a flaring
opening of usual form leading down to the oblong opening C. In the view shown,
the larger faces of the openings are shown horizontal as the preferable form,
instead of being vertical, as might possibly be the case with the re-arrangements
of the parts of the device.
D, is the metal coupling pin which is double-headed with flattened oblong
heads D', D", with the Hattened surfaces of these oblong heads shown substantially
in the same plane.
E, is a weighted rod which is fixed substantially midway between the oblong
heads D', D, of the pin in a plane substantially parallel to the upper and lower
surfaces of the oblong opening C, preferably by means of the collar F.
E', is a weight attachable to the end of the rod E, and E" is a chain which may-
be connected to an end of one of the cars which are coupled. This chain may be,
utilized for the purpose of obviating the necessity of the brakesman going between
the cars for the purpose of setting the device, for the purpose of coupling, or for
}

page_text: the purpose of uncoupling. It is obvious that when it is desired to couple cars, the
flattened surfaces of the heads of the pin D, must be turned into such a position as
to be capable of entering the opening at the end of the draw-head. As the
openings in the end of the draw-heads are shown in the views given here with their
larger faces horizontal, the pin must be turned into such a position that the flattened
oblong heads of the pin may be in a substantially horizontal position so as to
readily enter within the oblong openings in the end of the draw-heads. In Fig. 2, in
which one of the draw-heads is shown with a part broken away, G is one of the
locking chambers, of which there are two-G, G¹, both of which are shown in the
sectional view in Fig. 3, near the ends of their respective draw-heads. These
chambers are of sufficient size to permit of the heads of the pin to move freely
therein, and are provided at their upper and lower walls with circular holes H, so
that the draw-heads may be utilized for the ordinary pin coupling if both cars
be not provided with the device. In this Fig. 2, a car has been moved up towards
the car indicated in Fig. 1, and the head D has passed through the oblong
opening C', and has entered the locking chamber G, while the front wall of the
chamber has impinged against the collar F, and is about to move the oblong head D',
at the other end of the pin from its seat on the oblong opening C, already referred
to in Fig. 1. In this Fig. 2, as well as in Fig. 1, the coupling has not yet been
effected, consequently the weighted rod E, is in the substantially horizontal position
shown in these figures.
Should the locking chambers G, GI, be provided with rear walls, as indicated in
the drawings, the impact of the head against one of these rear walls may suffice
to move the other head from its seat in the opening on the adjoining draw-head so
that it may enter its locking chamber so as to be in a position to move when
locking is effected.
Figure 3, shows the device locked. In this view it will be seen that both of the
heads D', D" of the double-headed pin have entered their respective locking
chambers and being free to move, the weighted rod E, has fallen down by the force
of gravity to the perpendicular position indicated in this fig., and has caused the
double-headed pin to describe a quarter revolution, thus bringing the oblong heads
on either end of the pin into locking contact with the walls of the locking
chamber. The corners of the oblong openings C, C', should be preferably
rounded, as indicated in the drawings, so as to facilitate the entrance and exit of
the heads of the pin from their respective locking chambers. When it is desired
to uncouple the cars, the weighted rod E, is raised again to the position shown in
Figs. 1 and 2, so as to bring the flat surfaces of the oblong heads of the pin into a
substantially horizontal position so that they may be able to pass through either
of the oblong openings C, C', as may be desired. If it is desired to retain the
double-headed pin specially to either of the cars, the chain E", is utilized for the
purpose of attaching it thereto, so that when the car becomes uncoupled, the pin
remains with the car for which it is designed.
-b
Although the method shown of having the larger surfaces of the oblong
opening C, C', in a horizontal position, is preferable, it is obvious that these oblong
openings might be made with their larger surfaces vertical, in which case the
position of the weighted rod would have to be moved round on the pin ninety
degrees so as to cause the larger flat sides of the heads of the pin to be substantially
vertical when the pin is in a position to enter the end of the draw-head for coupling
purposes, in which case, as before, when both heads are within their respective
draw-heads, the dropping of the weighted rods to their vertical position will cause
the beads to move round through a quadrant of a circle so as to come into locking.
contact with the walls of the locking chamber, as already described.

tion and in what manner the same is to be performed, we declare that what wer
