lows: The reducing-valve for the air-whistle
signal is coupled onto the return-pipe from
the drum to the engineer's brake-valve, and
then a cut-out and release-cock is coupled to
5 the whistle-pipe, intended to charge the whis-
tle-line or close the same, the whistle-line
pipe being connected with the inlet-opening
19 in the bottom of the locking-cylinder.
Under this arrangement no person can tam-
io per with or turn off the air from any car or
at the rear end of the tank of the engine
without first having the release made by the
engineer or the man in charge of the engine.
It is evident that the attachment may be
I5 made to any angle-cock, and that by placing
the locking-piston at the bottom instead of
at the top of the angle-cock a more conven-
ient disposition is made of the said locking
device.
20 having thus described my invention, I
claim as new and desire to secure by Letters
Patent-
1. A train-pipe angle-cock having a manu-
ally-operated plug provided with an aper-
25 ture or recess, a locking device provided with
a non-rotatable stem or rod adapted to enter
the aperture or recess of the plug, and a con-
nection for fluid-pressure, separate from the
train-pipe, adapted to actuate said locking
30 device and secure the plug in position with-
out previous movement of the plug, substan-
tially as described.
2. A train-pipe angle-cock having a manu-
ally-operated plug, a locking device provided
35 with a cylinder attached to the bottom of thevalve-casing, immediately below the plug, a
tension device intervening the cylinder of the
locking device and the plug, having bearing
against both, the said cylinder being provided
with a spring-controlled piston the rod of 40
which is adapted to enter an opening in the
plug, the cylinder being connected at a point
below the piston with fluid-pressure under
control of the engineer and independent of
the train-pipe, as and for the purpose speci- 45
fled.
3. The combination, with an angle-cock
comprising a body, a valve or plug mounted
to turn therein, a handle connected with the
said plug to turn the same, the plug being 50
provided with an opening in its bottom, and
a flange extending downward around the bot-
tom portion of the plug, of a locking device
comprising a cylinder secured in the flange
portion of the casing and connected with fluid- 55
pressure under control of the engineer, a pis-
ton located in the said cylinder above its con-
nection with the fluid-pressure, a piston-rod
polygonal in cross-section, attached to the
piston and adapted to enter the opening in 60
the plug, a spring normally holding the pis-
ton in lower position and the piston-rod within
the cylinder, and a tension-spring seated in
the upper end of the cylinder and having
bearing against the bottom of the said plug, 65
as and for the purpose specified.
