Year: 1868

page_text: LETTERS PATENT to Philip Bauer, James Johnson, and William
Jones, all of Manchester, in the County of Lancaster, for tho
Invention of "CERTAIN IMPROVEMENTS IN APPARATUS TO BE EMPLOYED
FOR LUBRICATING REVOLVING SHAFTS OR AXLES."
Sealed the 14th August 1868, and dated the 20th February 1868.
PROVISIONAL SPECIFICATION left by the said Philip Bauer, James
Johnson, and William Jones at the Office of the Commissioners
of Patents, with their Petition, on the 20th February 1868.
We, PHILIP BAUER, JAMES JOHNSON, and WILLIAM JONES, all of
Manchester, in the County of Lancaster, do hereby declare the nature
of the said Invention for "CERTAIN IMPROVEMENTS IN APPARATUS TO BE
EMPLOYED FOR LUBRICATING REVOLVING SHAFTS OR AXLES," to be as follows:-
Our Invention relates to the lubrication of shafts, axles,. spindles, or
rollers which revolve in horizontal or slightly inclined bearings,. and
is designed to supply the lubricant thereto from a cavity in the lower

page_text: part of the bearing by means of bowls or rollers kept in contact with
the shaft or axle of the springs.
The improvements consist in mounting two or more metallic rollers
or bowls on a spindle or rod parallel to the shaft, so that one or the
uppermost portions of the peripheries of the rollers are in contact with
the revolving shaft, and the opposite or lowest parts of the peripheries
are immersed in oil or lubricant contained in a chamber in the bottom
part of the bearing "journal" or axle box, the bowls being kept in
constant contact with the revolving shaft by means of springs applied
to the bearings which support the shaft carrying the bowls, whereby
constant lubrication of the rotating shaft is effected. We would remark
that we are aware that bowls of cork, wood, and soft material have been
previously mounted on separate unadjustable spindles and revolving in
a chamber in the lower part of the bearing containing lubricant, but the
chief feature of the Invention consists in the use of metallic or hard
rollers all mounted on one spindle, which has springs applied to keep
the bowls constantly in contact with the shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philip Bauer, James Johnson, and William Jones
in the Great Seal Patent Office on the 20th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, PHILIP
BAUER, JAMES JOHNSON, and WILLIAM JONES, send greeting.
WHERAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenticth day of February, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Philip Bauer, James Johnson, and William
Jones, Her special license that we, the said Philip Bauer, James John-
son, and William Jones, our executors, administrators, and assigns, or
such others as they, the said Philip Bauer, James Johnson, and William
Jones, their executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might

page_text: make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "CERTAIN IMPROVEMENTS IN APPARATUS TO BE EMPLOYED FOR LUBRI-
CATING REVOLVING SHAFTS OR AXLES," upon the condition (amongst others)
that we, the said Philip Bauer, James Johnson, and William Jones, by
an instrument in writing under our hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Philip Bauer, James Johnson,
and William Joncs, do hereby declare the nature of the said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Drawings :-
Our Invention relates to the lubrication of shafts, axles, spindles, or
rollers which revolve in horizontal or slightly inclined bearings by means
of bowls, rollers, or discs kept in contact with the shaft or axle by
springs.
The improvements consist in mounting two or more metallic rollers
or bowls on one spindle or rod parallel with the shaft so that the
uppermost portion of the peripheries of the rollers are in contact with
the revolving shaft, and the opposite or lowest part of their peripherics
are immersed in oil or lubricant contained in a chamber in the bottom
part of the bearing journal or axle box, the bowls being kept in constant
contact with the revolving shaft by means of springs applied to the
bearings or rod supporting the shaft carrying the bowls, whereby
constant lubrication of the rotating shaft is effected.
In order that the Invention may be more fully explained and
understood in detail we have hereunto attached a Sheet of Drawing
made about full size, similar letters being marked on corresponding
parts on all the Figures alike.
Fig. 1 represents a longitudinal vertical section of a bearing or
pedestal of the ordinary kind supporting a revolving shaft, having applied
thereto our improved self-acting lubricators; Fig. 2 represents a vertical
transverse section of the same; and Fig. 3 represents an arrangement

page_text: of axle box, shewn in section, to which is applied the self-acting
lubricator.
In Figs. 1 and 2 a, a, is the shaft or axle, 6 the "steps" or brasses,
and c the pedestal or plumber block supporting the shaft a, all being
old and well-known parts of the supports or bearings for revolving
shafts; d, d, are two metallic rollers or bowls mounted and secured to
the rod e running parallel with the shaft a; the upper portion of the
peripheries of these rollers are in contact with the shaft a, and the lower
or opposite portions are immersed in the oil or lubricant contained in
the chamber or receptacle e¹ formed or constructed in the bottom of the
pedestal c; the bowls d, d, are kept in constant contact with the shaft a
by means of the coiled spring fapplied to and exerting a pressure upon
the bearing g supporting the rod e, the ends of the said rod being
governed or guided by the grooves h, h, formed in the sides of the
pedestal immediately underneath the vertical centre of the revolving
shaft a; the oil is fed into the chamber or receptical c through the
"duct" or thoroughfare i, the slotted plates k embracing the bowls,
seen in Fig. 3, being employed for the purpose of regulating the flow
of oil from the chamber e to the shaft a. Thus it will be seen that when
bowls d, d, by reason of their
the shaft a is revolving it will cause the
frictional contact with such shaft also to revolve and transfer the oil
or lubricant in the chamber e in a continuous stream to the shaft or
:axle the amount of which is governed or regulated by the slotted
plates; the surplus oil not used falling again into the chamber e effect
so long as the shaft or axle is in motion a constant and regular
circulation of the lubricant from the chamber e on to the shaft and into
the chamber again. We would remark that we are aware that bowls
of cork, wood, and soft material have been previously mounted on
separate unadjustable spindles and revolving in a chamber in the lower
part of the bearing containing lubricant, but the chief feature of our
Invention consists in the use of metallic or hard rollers, all mounted
ói 'one spindle-which has springs applied to keep the bowls constantly
in contact with the shaft.
Having now described the nature of our said Invention, together
with the method of carrying the same into practical effect, we would
wish it to be distinctly understood in conclusion that we claim,
the novel, employment, application, and use of metallic or hard
rollers kept in contact with a revolving shaft or axle by means of

page_text: springs to be employed for lubricating such shafts or axles, as
herein-before described, set forth, and fully illustrated in the Drawings
attached.
In witness whereof, we, the said Philip Bauer, James Johnson,
and William Jones, have hereunto attached our hands and seals,
this Nineteenth day of August One thousand eight hundred
and sixty-eight.
