WILLIAM HAYWOOD DAVIS, OF CHAPEL HILL, TEXAS, ASSIGNOR OF ONE-
HALF TO WILLIAM T. ARMSTRONG AND MILLER F. ARMSTRONG, OF
SAME PLACE.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 480,866, dated August 16, 1892.
Application filed October 10, 1891. Serial No. 408,289, (No model,)To all whom it may concern:
Be it known that I, WILLIAM HAYWOOD
DAVIS, a citizen of the United States, residing
at Chapel Hill, in the county of Washington
5 and State of Texas, have invented a new and
useful Car-Coupling, of which the following is
a specification.
This invention relates to car-couplings,
more especially of that class known as "hook-
to and-link;" and the object of the same is to ef-
fect certain improvements in devices of this
character.
To this end the invention consists in the
construction hereinafter more fully described
15 and claimed, and as illustrated on the accom-
panying sheet of drawings, wherein-
Figure 1 is a perspective view of the end of
a car with my coupling attached, taken slight-
ly from the upper and left side of the draw-
20 head. Fig. 2 is a central longitudinal section
of two draw-heads embodying my improve-
ments, a link being shown as coupled into the
right draw-head and supported by a link-lifter.
Fig. 3 is a front elevation of one draw-head.
25 Referring to the said drawings, 1 designates
the draw-head, which is suitably supported
beneath the car-body 2, and in the upper side
of whose open mouth is pivoted a depending
hook 3, a spring 4 holding the hook normally
30 vertical, as shown.
5 is a pin moving transversely across the
draw-head near the bottom of its mouth and
adapted to pass in front of and retain the
lower free end of the hook 3 in place, and
35 this pin has a notch 6 in its body, which per-
mits the hook to swing forward and allow the
link 7 to pull out when said notch is opposite
the tip of the hook. The pin is drawn nor-
mally inward by a coiled spring 8 on theleft
40 side of the draw-head, and at the opposite side
thereof a rod 9 is connected with the pin,
passes through an eye 10, preferably having
a roller 11, and is connected at its upper end
with a slide-rod 12, moving through suitable
45 guides 13 in the end of the car and having a
handle 14 at each end. By this construction
an operator standing at either side of the car
can move the slide-rod in the proper direction
to draw the pin out and bring the notch 6 op-
50o posite the tip of the hook, when the tensionon the link will cause it to draw out, and when
the slide-rod is released the spring 8 will cause
the pin to return to place and hold the hook
in operative position.
The link 7 preferably has a transverse bar 55
20 at its center, in which is an eye 21, and 22
is a chain having a snap-hook 23 at its end
adaptedto detachably engagesaid eye. Jour-
naled in bearings 24 in the rear end of the car
is an oscillating rod 25, having handles 26 at 60
its ends and a crank 27 at its center, to which
the chain is connected. By this construction
the operator standing at the side of the car
can manipulate the handle 26 so as to lift the
link and guide it into the mouth of an ap- 65
proaching draw-head. If the latterbe of the
construction above described, the free end of
the link will bear the hook to the rear and
pass under its tip,when the spring 4 will throw
said tip down into the link and lock the latter 70
in place; but it will be understood that the
link may be locked into draw-heads of the
usual construction, and this I claim as one of
the special advantages of this device.
I do not limit myself to the use of a link- 75
lifter, nor to the precise details of construc-
tion or the size or materials of parts, and va-
rious changes in and additions to this coup-
ling may be made without departing from the
spirit of my invention. 80
I claim as the salient features of this inven-
tion-
1. In a car-coupling, the combination of
a draw -head, a depending hook pivotally
mounted therein, a transverse pin arranged 85
on the bottom of the mouth of the draw-head
and provided intermediate its ends with a
notch to permit the passage of the lower end
of the hook, a spring for holding the notch
away from the hook, and means for sliding 90o
the pin to bring the notch opposite the hook,
substantially as described.
2. In a car-coupling, the combination, with
the draw-head, a hook mounted on a trans-
verse pivot in the upper part of the mouth of 95
said draw-head, and a spring holding said hook
normally vertical, of a transverse pin moving
across the bottom of said mouth and having
a notch in its body adapted to permit the out-
ward passage of the tip of the hook, a slide- ioo
