UNITED STATES PATENT OFFICE
RICHARD FIELDS ADAMS, OF PALESTINE, TEXAS.
AUTOMATIC OILER.
Specification of Letters Patent. Patented Jan. 17, 1911.
Application filed June 8, 1909. Serial No. 500,804.To all whom it may concern:
Be it known that I, RICI-HAIlD FIELDS
ADAMS, a citizen of the United States, re-
siding at Palestine, in the county of Ancler-
. son and State of Texas, have invented a
new and useful Automatic Oiler, of which
the following is a specification.
This invention relates to automatic oilers
for vehicles, particularly for railroad cars
or coaches and consists in the novel con-
struction and arrangement of parts as here-
inafter shown and described.
The object of the invention is to provide a
simple and an efficient mechanism for oiling
15 journal bearings of a vehicle of the char-
acter indicated while the vehicle is in mo-
tion.
In the accompanying drawings :-Figure
1 is a bottom plan view of the device show-
20 ing parts thereof in section. Fig. 2 is a
transverse sectional view of the device.
Fig. 3 is a detail view of a yielding link
which forms a part of the device. Fig. 4
is a perspective view of a portion of the de-
25 vice with parts broken away and parts re-
moved. Fig. 5 is a cross sectional view
through a valve which is a component part
of the device.
In the accompanying drawing 1 desig-
30 nates the body of a railroad car or coach
having end sills 2 and drawheads 3. Se-
cured to the body 1 of the car are trucks 4
having side frames 5 which carry journal
boxes 7 for the axles 6. An oil reservoir 8
35 is suspended from the under side of the
body of the car by straps 9. Leading from
the said reservoir is a main feed pipe 10
provided with a main valve 11 for regulat-
ing the flow of oil from the reservoir
40 through the said main feed pipe and an
auxiliary valve 12 for regulating the flow
of oil from the main pipe through its
branches 13. The branches 13 extend along
the under side of the body of the car and
45 terminate in Y-shaped branches 14 over-
lying the journal boxes 7 and communicat-
ing with the journals. To inclose the valves
11 and 12 and secure them from being un-
duly tampered with a casing 15 is provided.
50 This casing may be hung to the bottom of
the car if desired. Positioned longitudi-
nally of the casing is a beam 18 which is
secured to the under side of the car body
and supports the automatic regulating de-
55 vice which will now be described.
The stem 19 of the valve 12 terminates ina transversely disposed arm 20, to the ends
of which the inner ends of springs 21 are at-
tached. Yielding links 22 are also attached
at their inner ends to the ends of the arm
20. The outer portions of the yielding
links are slidingly fitted in brackets 23 car-
ried by the beam 18 and are connected in-
directly to the drawheads 3. Each yielding
link 22 is preferably formed of a pair of 6
rods each terminating at one end in an eye
to engage and slidingly fit the shank of the
other. The coil springs 24 are arranged in-
termediate the eyes and operate to hold said
eyes spaced when in normal position. The 70
distance between the terminal eye of the
rod connected with the valve stem and the.
bracket 23 is made great enough to permit
the valve to be wide open when the eye is in
contact with the bracket. When the parts 75
are in this position any further movement
of the drawhead will not be transmitted to
the valve stem but will be taken up by the
coil springs. The outer ends of the coil
springs 21 are secured to the brackets 23 and so
exert pressure on the arms 20 counter to the
operating movement of the yielding links 22
whereby to normally hold the valve closed.
Secured to the free end of each yielding
link 22 is a lever 25 which is pivotally se- 85
cured to the under side of the body of the
car. A link 27 is attached at one end to the
lever 25 and also to one end of a coil spring
30. The other end of the link 27 is attached
to one end of a lever 29 fulcrumed to the car 90
body 1. The said coil spring is secured at
its opposite end to the car body 1 and exerts
a pressure on the lever 25 in the direction of
the drawhead 3, the purpose of this coil
spring being to modify the jerky motion im- 95
parted to the lever by the drawhead.
The free end of the lever 29 is attached to
a connecting rod 32 which extends through
the casing and is secured at its outer end to
the rear end of the drawhead 3. As may 100
readily be seen by this construction when
the train is in motion the drawhead is pulled
out of its normal position and so held. This
motion is transmitted through the connect-
ing rod 32, lever 29, link 27, lever 25, and 105
the yielding link 22, to the stem 19 of the
valve 12, opens the valve 12 and holds it
open. When the train comes to a stop the
motion is reversed, and aided by the coil
spring 21 the valve stem is returned to its 110
normal position and held there until the
train is put in motion. In this way when
