COMPLETE SPECIFICATION.
Improvements in Car Couplers.
I, CHRISTOPHER DUTCHBURN, of Highfield, in the County of York and Province
of Ontario, Dominion of Canada, Farmer, 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:-
My invention relates to car couplers of that class in which pins and links are
used, and in which the pins and links are operated through the medium of rock
shafts mounted at the ends of the cars, and extending to the sides thereof to avoid
the necessity of trainmen passing between the cars.
This specification is the disclosure of one form of my invention, while the
claims define the actual scope of the conception.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all figures.
Figure 1 is a side elevation of the invention;
Figure 2 is a sectional view on the line 2-2 of Figure 3;
Figure 3 is a sectional view on the line 3-3 of Figure 2; and
Figure 4 is an end elevation of the invention.
The draw bars 5, carry the coupling heads 6 which have throats 7, and cavi-
ties 8 subjacent to the throats, the cavities 8 being divided by a vertical
partition 9. Extending transversely through each coupling head is a shaft 10,
each shaft carrying two lifting cams 11, fixed on the shafts and respectively
located within the cavities S. The cams 11 serve to lift the links as indicated in
Figure 2, which lifting of the links is necessary to the coupling operation.
Pins 12 slide vertically through passages 13 respectively formed in the rear
of the coupling heads. Each coupling head has a horizontally sliding plate 14,
crossing the passages 13 of the coupling head and serving to support the pins 12,
as shown in Figure 3. The plate 14, of each coupling head is pivoted to a
wing 15, hinged to one side of the coupling head 6 and pressed against the coup-
ling head by a leaf spring 16. Each coupling head has a ledge 17, overhanging
the wing 15 and spring 16, whereby to protect the same.. Each wing 15 has a
cam-shaped lug 18 formed on its inner face, and projecting through an orifice
in the side of the coupling head. These lugs 18 extend into the respective
throats 7. In operation the pins 12 are supported out of the throats 7 by the
plate 14. The link 9" when projected into one of the throats engages the lug 18
thereof and pushes outward the wing 15, which in turn withdraws the corre-
sponding plate 14 and allows the pin 12 to drop into engagement with the
link 9".
Mounted at each end of the car are two rock shafts 20 and 21, having at their
ends crank arms 22 and 23. An intermediate portion of each crank shaft also
has a crank arm 24 and 25. The crank arm 25 is pivoted to a link 26 in turn
connected to the pin 12 of the adjacent coupling. The crank arm 24 is pivoted
to a link 27, which is pivoted in turn to a crank 28, fixed on the shaft 10 of the
adjacent coupling. By these means the cams 11 and the pins 12 may be manipu-
lated readily, without requiring the trainmen to pass between the cars.
Each

page_text: cam 11 has a rib or flange 11" at its outer upper corner. Between these ribs in
each pair of cams the links 9 lie.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The combination with a coupling head having a throat and a ledge extend-
ing out from one side of the throat, of a plate sliding horizontally through the
coupling head and serving to support a pin out of the throat, a wing attached
to the plate and having a lug projecting into the throat, the wing being located
beneath the ledge of the coupling head, and a spring pressing the wing inward
and also located beneath the ledge.
2. In a car coupling, the combination of a coupling head having a vertical
passage run there through to receive the pin, and having a horizontal passage
intersecting in the vertical passage, a plate sliding through the horizontal
passage and capable of supporting a pin in the vertical passage, a wing pivoted
to the outer side of the coupling head and attached to the plate, and a spring
pressing the wing to hold the plate inward, the coupling head having a ledge
overhanging the wing to protect the same.
Dated this 5th day of November 1898.
