CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 612,280, dated October 11, 1898.
Application filed July 7, 1898. Serial No. 685,329. (No model)To all whom it 7mayf coflce'n:
Be it known that I, JOHN G. SHERRILL, of
Gordon, in the county of Palo Pinto and State
of Texas, have invented a new and Improved
5 Car-Coupling, of which the following is a full,
clear, and exact description.
This invention relates to car-couplings of
the hook-and-catch type adapted for an auto-
matic coupled engagement with each other,
1o and has for its object to provide a car-coup-
ling of the class indicated of novel simple
construction and reliable in operation and
which also affords convenient means for the
release of the coupled cars.
15 The invention consists in the novel con-
struction and combination of parts, as here-
inafter described,and defined in the appended
claims.
Reference is to be had to the accompanying
20 drawings, forming a part of this specification,
in which similar characters of reference indi-
cate corresponding parts in all the figures.
Figure 1 is a side elevation of portions of
two cars having the improved couplings
25 thereon and in coupled adjustment. Fig. 2
is an enlarged partly-sectional side view of
the improved car-coupling substantially on
the line 2 2 in Fig. 4. Fig. 3 is a sectional
plan view showing details of construction
30 substantially on the line 3 3 in Fig. 6. Fig.
4 is a partly-sectional plan view of two coup-
lings in alinement and ready to be coupled
together, the line of section for each coupling
being indicated by the line 4 4 in Fig. 8. Fig.
35 5 is a partly-sectional side view of the im-
proved car-coupling with parts in coupled
condition, the line of section being indicated
at 55'in Fig. 7. Fig. 6 is a partly-sectional
side view of details essentially on the line 6 6
40 in Fig. 4, showing the parts in uncoupled con-
dition Fig. 7 is a front end view of the im-
proved car-coupling in coupled adjustment.
Fig. 8 is a side view of one end of a car-body
and of the improved car-coupling thereon in
45 uncoupled adjustment. Fig. 9 is an enlarged
sectional side elevation on the line 9 9 in Fig.
10; and Fig. 10 is a transverse sectional view
of details, taken substantially on the line
10 10 in Fig. 9.
50 In carrying into effect the features of in-
vention to be described, A represents a car-body of ordinary form, whereon the draw-bar
10 and the draw-head 11 are held by any suit-
able means, so as to project the draw-head in
advance of the car-body at its transverse cen- 55
ter, as usual.
The draw-head as preferably constructed
is substantially rectangular exteriorly and
at the front end may have reinforcing-ribs
formed on the upper and lower sides. The 6o
body of the draw-head 11 is recessed near its
center from the front end rearwardly, pro-
ducing a chamber a, and the upper and lower
walls of said chamber may be oppositely per-
forated to receive a coupling-pin B, which 65
when in place will hold a common coupling-
link within the chamber a should it be de-
sirable to temporarily couple together two of
the improved car-couplings or to couple one
of the improved couplings to any other style 70
of car-coupling.
At the left-hand side of the draw-head 11 a
recess b is formed therein, which is mainly
circular in contour, but cuts through the up-
per side of the draw-head, said recess having 75
sufficient depth to permit the loose introduc-
tion therein of the coupling-hook 12, formed
at its rear end to loosely fit within the circu-
lar wall of the recess b, as is clearly shown in
Figs. 5 and G. The forward portion 12- of the 8o
hook 12 is preferably formed essentially right-
angular, so as to afford a depending limb
thereon for engagement with a loop formation
13, that projects at the right-hand side of a
similar draw-head, when two of the improved 85
car-couplings are to be coupled together, as
will be hereinafter further explained.
At the center of the circular rear end of the
coupling-hook 12 a square or other angular
perforation is produced for the reception of 90
the squared portion of a shaft c, having jour-
nals on each end which loosely engage perfo-
rations in the wall of the draw-head and a
cap-plate thereon.
In the left-hand side wall of the draw-head 95
11, between the chamber a and the recess b,
that receives the hook 12, another recess b' is
formed, the inner portion of which is square
to permit the slidable insertion of the rectan-
gular body portion 14 of a pusher-bar therein, m oo
furnished with an enlarged head 143, which
projects normally at the front end of the
