SAMUEL R. HEIDELBERG, OF PALESTINE, ASSIGNOR OF ONE-HALF TO II. IT.
ROWLAND, OF TYLER, TEXAS.
LOCOMOTIVE-PILOT COUPLING.
SPECIFICATION forming part of Letters Patent No. 553,340, dated January 21, 1896.
Application filed September 19, 1895. Serial No, 563,038. (No model.)To all whonq it )zmay concern:
Be it known that I,SAMUEL R. HEIDELBERG,
a citizen of the United States, residing at Pal-
estine, in the county of Anderson and State
5 of Texas, have invented certain new and use-
ful Improvements in Locomotive-Pilot Coup-
lings, of which the following is a specification.
This invention relates to certain new and
useful improvements in locomotive -pilot
io couplings; and it consists substantially in
such features of construction, arrangement,
and combinations of parts as will hereinafter
be more particularly described.
The invention has reference more particu-
15 larly to the means by which the bar is elevated
or raised to a position for coupling, and it has
for its object to simplify such means and to
render the same much more reliable and ef-
fective than heretofore.
20 A further object is the conformability of
the lifting devices or mechanism to the lat-
eral or swinging movements of the bar in the
rounding of curves or sharp bends, and also
to prevent shock and undue strain upon the
25 devices in the application of the motive power
to operate the same.
A still further object of the invention is the
more secure coupling of the pilot or draw bar
with a car or other vehicle, as well as the easy
30 and ready aligning of the bar whenever a coup-
ling thereof is being made upon curves or
bends in the track, and, finally, the invention
has for its object the automatic release of the
jaw of the coupler-head of the bar so as to
35 bring the same to an open position each time
the bar is lowered upon the pilot.
The above objects I attain by the means
illustrated in the accompanying drawings, in
which-
40 Figure 1 is a side elevation in part section
representing my improved lifting mechanism
as located and arranged with respect to the
pilot of a locomotive, the dotted lines repre-
senting the pilot-bar in its raised or elevated
45 position. Fig. 2 is a front elevation repre-
senting the means by which the baris turned
or swung to one side for effecting alignment
thereof with a coupler-section on a car or other
vehicle. Fig. 3 is an enlarged view in detail
50 representing the means for automatically re-
leasing and opening the jaw of the coupler-section of the draw-bar whenever the latter is
lowered into position upon the pilot. Fig. 4
is an enlarged view in part section of the
coupler-section of the draw-bar. Fig. 5 is a 55
plan view of a coupler-section of the ordinary
Janney type. Fig. 6 is an enlarged vertical
sectional elevation of the devices or mechan-
ism by which the lifting of the draw-bar is
effected on the admission of a suitable motor 6o
fluid.
In the practice of my invention I employ
in connection with the pilot or draw bar a
suitable lifting-rod that is actuated by a pis-
ton on admission to the piston-cylinder of the 65
motor fluid, and while various constructions
could be resorted to for the purpose I prefer
the general construction and arrangement of
devices herein shown, and as willhereinafter
be more particularly described. The devices 70
are under the control of the engineer or other
operator in the cab of the engine, and while
I may use either steam or air as the motor
fluid I prefer the latter in a compressed state,
and which, instead of being supplied from 75
the same source as that which supplies the
air-brakes, is stored up in a separate tank or
reservoir located beneath the locomotive or
other convenient point. I furthermore re-
sort to the use of a peculiar form of coupler- 8o
section designed to operate in connection with
any of the ordinary sections of the Janney
type, and in order to enable lateral turning
of the bar for the purposes of alignment I
employ suitable hand-operated devices, also 85
more specifically described hereinafter.
Referring to the accompanying drawings,
1 represents the front cross-piece of an ordi-
nary locomotive, and 2 the pilot or cow-
catcher, which is of ordinary form and which 90
is supported or held in position in any suit-
able manner. Centrally of the said cross-
piece I is arranged an ordinary draw-head 3,
in which is held or supported loosely by means
of a pin 4 the pilot or draw bar 5, which is of 95
the usual or well-known form. To effect the
raising or lifting of the said bar to a horizon-
tal position I employ beneath the pilot and in
suitable supports therefor the devices which
are under the control of the engineer in the Ico
cab of the engine, and which are set into mo-
tion on the admission of air or other suitable
