Specification Accepted, 27th Apr., 1888
I, WILLIAM HUMPHREY WHEATLEY of 156 Strand in the County of Middlesex
Consulting Engineer and Patent Agent, do hereby declare the nature of this
invention, and in what manner the same is to be performed to be particularly.
described and ascertained in and by the following statement :-
The objects of my invention are economy in the use of the Lubricant, to provide a
continuously lubricated Car Axle journal, to confine and protect the lubricant and
prevent deposits of said dust or other gritty material upon the Car Axle journal and
in the Lubricant. I attain these objects by the mechanism illustrated in the
accompanying drawings in which
Fig. 1. is a vertical cross section of a car axle box showing the device and its
relation to the car axle journal.
Fig. 2. is a sectional view on line 2 Fig. 1.
Fig. 3. is a view in perspective of the frame and spring with roller removed.
Similar letters refer to similar parts throughout the drawings.
Two metal bars D' D' of a suitable length to be placed in a car axle box joined by
two bolts a, b, and a flat metal rubbing bar d, constitute the frame of my device in
which is journaled the Roller E.
The flat metal rubbing bar d, encloses the end of the frame nearest the roller E
and inclines so that the lower side is in such proximity to the roller as to permit the
Roller E to slightly rub against it to remove any excess of oil while serving the
journal A.
The Roller E is journaled in the frame at c and revolving in the lubricant confined
underneath it by the frame engaging with the journal A keeps it continuously
lubricated.
In order to relieve the roller E from the violent action of the car axle journal and
to allow it to engage with it yieldingly I support the end of the frame under the
roller by the steel spring F which is made from one piece of steel wire bent in the

page_text: form of a bow having the two ends coiled and affixed to the bolt b, the bow resting
upon the bottom of the car axle box B.
In the construction of the frame I cast or forge the bar D³, the bolts a, b, and
rubbing bar d as one piece, this enables me to place the device under the car axle
journal A in the box B without removing the box B from its position, the parts above
mentioned are easily placed in proper position in the car axle box when the other
parts including the roller may follow in their proper order and secured as shown in
the illustration. The bolt a is beveled on the side contiguous to the roller and near
enough to the roller to permit it to slightly rub against it to remove any excess of oil
when the movement of the car is reversed, and prevents the splashing of the oil or
lubricating material causing unnecessary waste.
h
An apron projects from the side of the bar D' which is intended to serve as a
cover for that portion of the lubricant in the box B not enclosed by the frame.
A metal cover is placed over the top of the frame so as to fit up closely to the
roller E thus enclosing completely the lubricant in the car axle box and preventing
it from splashing or dripping from the box; and also excluding sand and dust.
I attach to the upper side of the apron on the bar D2 or to the bar D¹ or to both
when it may better serve my purpose a vertical thin brass plate or shield H which is
cut circular in form on its upper edge so as to conform with the exposed segment of
the journal A and fits closely to the same. In the usual method of construction of
the car axle box B, the rear end thereof and occasionally both ends contain an aperture
or opening through which dust and sand penetrates the journal box and is deposited
on the axle journal and oil beneath it, also permitting the oil to escape or drip from
the box while the car is in motion.
The brass plate or shield H is intended to cover the apertures and this more
effectually confine and protect the lubricant and journal.
The axle of the Roller E has two brass washers or flanges g, g, secured to it.
On the spool thus constructed I wind between the flanges or washers canvas, cloth,
felt, or other porous material to form the roller of my improved device.
Being aware that heretofore lubricators have been constructed by having rollers
of various kinds engage with the car axle journal I do not in this specification claim
such a combination broadly but what I do claim and desire to secure by Letters
Patent is
1. The combination of the Roller E journaled in the frame D1 D2 at C. the beveled
bolt a, bolt b, flat rubbing bar d, metal cover and bow spring F as and for the
purpose above set forth.
2. The combination of the flat rubbing bar d, the beveled bolt a, and cover k for
the purpose of cleaning the roller as above described.
3. The combination of the washers or flanges g, g, axle x, wound with canvas, felt
cloth or other porous material to form a roller for a lubricating device as above
described.
4. The combination of the Roller E, metal frame D¹ D² beveled bolt a, bolt b,
rubbing bar d, apron h, cover k, bow spring F, and vertical brass plate or shield H,
for the purpose of constructing a car axle Lubricator as above described.
Dated this 14th day of February 1888.
