Improvements in and connected with Journal-boxes.
We, ANDREW DINGWELL Cox, Inventor, and THERON SHARP, Gentleman,
both of West Winchester, Ontario, Canada, 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 :-
This invention relates to certain new and useful improvements in journal-boxes
of that class provided with an oil-chamber at the bottom of the box, and provided
with a peripheral groove which is adapted to receive a collar secured to the shaft
by means of which and said collar the oil is taken up and caused to be distributed
upon the shaft. I also provide conduits for the oil so that the surplus finds its way
back to the oil chamber and thus prevents waste of the same. By this construction
I am able to provide a journal-box which is self-oiling and which may be used in
any temperature, and with any grade of oil.
To these ends, and to such others as the invention may pertain, the same consists
in the peculiar construction and in the novel arrangement, combination, and adaption
of parts, all as more fully hereinafter described, shown in the accompanying
drawings and then specifically defined in the appended claims.
The invention is clearly illustrated in the accompanying drawings which with
the letters of reference marked thereon form a part of this Specification, like
letters of reference indicating like parts throughout the several views, and in
which drawings
Figure 1 is a perspective view of a journal-box constructed in accordance
with my invention.
Fig. 2 is a central longitudinal section on the line ca of Fig. 1.
Fig. 3 is a central transverse section of the line y y of Fig. 1.
Fig. 4 is a sectional detail view of the oil feeder.
Referring now to the details of the drawings by letter: A is the journal-box,
which is cylindrical in form and is formed at its longitudinal centre with a raised
portion A, to the faces of which the screws or other means for attaching the box
to the hangings may be applied.
B is a shell bushed with babbit metal which forms the bearing for the lower
portion of the shaft, which shell is provided upon its outer lower ends with
shoulders b, which rest upon shoulders, formed in the journal-box A, for that
purpose. Between said journal-box and the shell B, is a suitable oil chamber b³,
which extends substantially the length of the journal-box.
C is a bearing bushed with babbit metal for the upper part of the shaft and is
fitted into the journal-box A, in the same manner as the corresponding bearing B.
The said bearing C is formed in two pieces, as will be seen, so that one piece is
placed upon each side of the peripheral groove hereinafter described.
D, is the oil feeder, which consists of a collar of metal divided into sections two
in number, which sections are provided at their ends with means whereby the
sections may be united. In the present instance I have shown the ends provided
with ears d, through which a pin or screw may be passed to secure them together.
This collar is fitted upon the shaft and is adapted to revolve therewith within a
peripheral groove d', formed in the inner face of the journal-box for this purpose.
The manner of attaching the said collar to the shaft is as follows: I cut away the
inner face of the collar upon opposite sides, and in one side I place a piece of
leather d, or its equivalent, and in the other side is placed a flat spring d³, as
shown, which is adapted to bear against the said shaft, and by reason of its friction
therewith, cause the said collar to revolve therewith, and yet permit such

page_text: lateral movement thereon as may be necessary by the expansion or contraction
of the shaft.
The collar D is provided upon its outer face with a series of inclined or curved
wings or arms d', which are adapted to take up the oil from the oil-chamber in the
lower portion of the journal-box and the inclined slots E, which are provided
within the inner face of the box-lining, serve to cause the oil that is thus carried
upward to be evenly distributed upon the surface of the shaft, and also insure the
return of the surplus oil to the oil-chamber, thus preventing possible waste. While
I have shown but a single feeder in connection with the journal-box illustrated in
the drawings, it is evident that in case the box were long, two or more of these
collars could be used if desired.
F is an arm extending horizontally from the lower portion of the journal-box.
This extension is provided with a horizontal aperture F', communicating at its
inner end with the interior of the oil-chamber in the journal-box, and at its outer
end is provided with a suitable removable cap or cover f, which may be removed
when it is necessary to clean or remove the oil from the chamber. A vertical
aperture near the outer end of the extension and communicating with the
opening is utilized for filling the oil-chamber, and as the entrance of the
aperture is upon a higher level than the top of the oil-chamber it will be
readily seen that by keeping the same filled with oil, that the said chamber will be
supplied, and that the amount of oil within the chamber may be at any time deter-
mined by noting the height of the oil within the aperture.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1. A journal-box for shafts provided with an oil-chamber, and means substan-
tially as described for automatically conveying the oil from the oil-chamber to the
surface of the shaft during the rotation of the same, substantially as described.
2. A journal-box for shafts, the same consisting in a suitable casing, the lower
portion of which is provided with an oil-chamber, and means substantially as
described for automatically conveying the oil from the oil chamber to the surface
of the shaft during the rotation of the same, and inclined oil-ways through which
the surplus oil is returned to the oil-chamber, substantially as described and for
the purpose specified.
3. In a journal-box, the lower portion of which is provided with an oil-chamber,
of an oil-carrier mounted upon the shaft within the box, and provided upon its
periphery with a series of arms adapted to convey the oil to the upper portion of
the box during the rotation of the shaft, and means substantially as described, for
insuring a return of the surplus oil to the oil-chamber.
4. The combination, with the journal-box provided with an oil-chamber in its
lower portion, of a filling aperture communicating with the oil-chamber, substan-
tially as described.
