WILLIAM G. FELKNER, OF SEBREE, TEXAS.
TRAIN-PIPE COUPLING.Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed November 22, 1907. Serial No. 403,351.
To all whom it may.concern:
Be it known that I, WILLIAM G. FELKNER,
citizen of the United States, residing at Se-
bree, in the county of Jack and State of
5 Texas, have invented certain new and useful
Improvements in Train-Pipe Couplings, of
which the following is a specification.
This invention contemplates certain new
and useful improvements in that type of hose
10 couplings embodying automatically acting
valves that are arranged to close so as to shut
off the flow or passage of the air, water, or
other fluid, and relates particularly in its
present adaptation to an automatic hose
15 coupling of this character for the train pipes
or other pipes of air brake systems of railway
cars designed to instantly and automatic-
ally close the train pipe whenever one
car is detached from a train or a break made
20 between any two cars, although the inven-
tion is of course applicable to the coupling
together of pipes generally.
The invention has for its object a simple,
durable and efficient construction of appa-
25 ratus of this character which may be cheaply
made and installed and which is composed of
comparatively few and simple parts that will
not be liable to get out of order and that will
readily and automatically connect together
30 when the cars are coupled, and the invention
consists in certain constructions, arrange-
ments and combinations of the parts that I
shall hereinafter fully describe and claim.
For a full understanding of the invention,
35 reference is to be had to the following de-
scription and accompanying drawings, in
which:
Figure 1 is a longitudinal sectional view of
a train pipe joint effected by the use of my
40 improved hose couplings, the flexible hose
members being shown broken out in order to
economize space; Fig. 2 is a perspective view
of the joint; and, Fig. 3 is a detail perspec-
tive view on a somewhat enlarged scale of the
45 valve employed.
Corresponding and like parts are referred
to in the following description and indicated
in all the views of the drawings by the same
reference characters.
50 Referring to the drawings, the numeral 1
designates the two train pipes of an air brake
system at the adjoining ends of two cars, and
2 designates the valve casings of my improved
hose coupling, there being one of these em-
55 ployed for each end of a train pipe, that is,
one at each end of a car. Each valve casing2 may be connected at one end in a detach-
able manner to the train pipe, as by the
union or other coupling 3, or by any other
desired means, and the other end of the valve 60
casing has formed integrally therewith, or
secured thereto, in any desired way, a flared
socket portion 4. One end of a flexible hose
pipe connecting member 5 is designed to be
wedged in the socket portion 4 so as to be 65
held by frictional engagement. Each valve
casing 2 is formed with a laterally and pref-
erably angular branch 6 to which one end of
the complemental hose pipe coupling member
5 is connected, it being understood, as clearly 70
illustrated in the drawing, that the flared
socket end 4 of one valve casing faces the end
of the branch 6 of the complemental valve
casing on the adjoining car. Preferably one
end of each hose pipe coupling member 5 is 75
formed with a metallic tip 7 to wedge se-
curely in the socket 4, and the opposite end
of each hose pipe coupling member 5 may be
detachably secured to the branch 6 of the
valve casing by means of the swivel coupling so
8 or other desired fastening. Each valve
casing 2 contains a valve which, in the pres-
ent instance, as best seen in Fig. 3, comprises
a disk-like head 9, a plurality of spaced rods
10 secured at one end thereto, and an annular 85
or ring-like abutment member 11 secured to
the other end of said rod. The valve is
mounted to move longitudinally in the valve
casing, as shown, and the rods extend en-
tirely therethrough, the abutment member so
11 being mounted in the tapered socket 4.
The entire valve is longer than the distance
between the base of the socket 4 and the
valve seat 9.
From the foregoing description in connec- o5
tion with the accompanying drawing, it will
be seen that in the practical application of
my improved automatic hose coupling mech-
anism, when the detached end of a hose pipe
coupling member 5 is pressed inwardly into 1c
a socket 4, it will engage the abutment mem-
ber 11 and move the valve 9 to an open po-
sition and maintain it in such position so
long as the parts are coupled together.
Whenever any break occurs, it is obvious that 105
the tip end 7 of either one or both of the hose
pipe coupling members 5 will be withdrawn
from its corresponding socket and the air
pressure will instantly cause the valve 9 to
seat, to cut off the flow of train pipe air. It 110
is to be understood that one end of each
flexible coupling member 5 is permanently,No. 895,735.
