Improvements in Lubricators for Lubricating the Sliding and
Working Surfaces of Machine Tools and Engines, such as
Turning Lathes, Milling, Shaping, and Slotting Machines,
Planing Machines for Iron and Stone, and the Cross Head Slides
of Steam and Gas Engines.
HENRY BUTTERFIELD, SS, Occupation Lane, Staincliff, in the Parish of
Batley & the West Riding of the County of York, by trade an Engineer, also
WILBEY Fox, Engineer, of 56, Hume Street, Batley, in the West Riding of the
County of York, do hereby declare the nature of this invention to be as follows :-
The object of our invention is the lubrication of the working & sliding
surfaces of machine tools & engines such as turning lathes, milling, shaping
& slotting machines and planing machines for iron & stone, and the cross head
slides of steam & gas engines; so as to thoroughly & economically distribute
the lubricant over the surfaces working together, and prevent the lubricant from
becoming fouled with dust grit & refuse material, from the object, being operated
upon in the machine. The lubricator consists of a narrow box of brass or other
suitable material, provided with a lid to exclude dust etc.; which is fixed on the
face of the part of the machine, travelling over the bed or stationary surface of
the machine to be lubricated. Inside, the box is divided into two compart-
ments by a midfeather. The lower division is open at the bottom; into
which a piece of india rubber on edge is tightly fitted, which projects a little
way out of the bottom, & presses upon the stationary surface.
While the moving
part of the machine (to which the lubricator is fixed,) is in motion, the rubber
travelling over the lubricated surface, sweeps any dust, grit or refuse before it, &
prevents the lubricant being applied from becoming fouled thereby & also keeps
dust, etc. from accumulating between the lubricated surfaces working together, and
in returning, the rubber sweeps the lubricant which has been applied back again
into the lubricator. The upper division of the lubricator is intended to contain the
lubricant which flows from it through holes, or channels in the back of the lubricator
to the surfaces to be lubricated.

improvements in Lubricators for Lubricating the Sliding and
Working Surfaces of Machine Tools and Engines, such as
Turning Lathes, Milling, Shaping, and Slotting Machines,
Planing Machines for Iron and Stone, and the Cross Head Slides
of Steam and Gas Engines.
We, HENRY BUTTERFIELD, of 88, Occupation Lane, Staincliffe, in the Parish
of Batley, in the West Riding of the County of York, Engineer, and WILBEY
Fox, of 56, Hume Street, Batley, in the West Riding of the County of York,
Engineer, 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 object of our invention is the lubrication of the working and sliding
surfaces of machine tools and engines, such as turning lathes, milling, shaping,
and slotting machines, planing machines for iron, stone, and the crosshead slides

page_text: of steam and gas engines; so as to thoroughly and economically distribute the
lubricant over the surfaces working together, and to prevent the lubricant
becoming fouled with dust, grit, and refuse material from the object being operated
upon in the machine.
The lubricator consists of a narrow box of brass or other suitable material, provided
with a lid to exclude the dust. etc. This box is cast on or more preferably attached to
the end or face of that part of the machine travelling over the bed or stationary
part of the machine to be lubricated. The box is divided internally into two com-
partments by a midfeather. The lower division is open at the bottom, into which a
piece of india-rubber on edge is tightly fitted, and which projects a little way out of
the bottom and presses on the stationary surface.
Whilst the moving part of the machine, (to which the lubricator is fixed,) is in
motion, the rubber travelling over the surface to be lubricated sweeps any dust
grit or refuse before it, and prevents the lubricant which is being applied from
becoming fouled thereby, and also keeps dust etc. from accumulating between the
lubricating surfaces working together, and in returning the rubber sweeps the
lubricant back into the lubricator. The upper division of the lubricator is intended
to contain the lubricant which flows from it through holes or channels in the back of
the lubricator, to the surfaces to be lubricated.
And in order that our invention and the manner in which the same is to be
performed may be more clearly and readily understood reference is given to the
accompanying drawings and to the letters and marks thereon, in which,
Fig. 1 is a longitudinal elevation,
Fig. 2 is a plan looking down upon the top,
Fig. 3 is a longitudinal vertical section,
Fig. 4 is a longitudinal horizontal section,
Fig. 5 is a cross vertical section, and
Fig. 6 is an end elevation of a lubricator constructed in accordance with our
invention; whilst
Fig. 7 is a half end elevation of the saddle of a lathe to which our lubricator
has been attached.
The same letters refer to the same parts in all the figures.
.
a is the box or lubricator divided into an upper and lower division by a hori-
zontal midfeather ; and contains in its upper division the lubricant, and in its
lower division the rubber scraper c, which projects slightly below the bottom edge
of the lubricator box. d is a cover or cap to exclude dust etc. from the lubricant
contained in the upper division of a. e. e. are two slot holes for screws, by means
of which the lubricator is attached to the end or face of the moving part of the
machine (ie. the cross saddle in Fig. 7). Small grease holes .. allow the escape
of lubricant, from the upper division containing the same, between the box and the
end or face of the travelling part of the machine to which it is affixed, the escape of
such lubricant being prevented by the rubber scraper c. The back of the lubricator
next to the moving part of the machine is preferably slightly recessed as is shewn
in the drawings Figs. 4 and 5, and thus forms a sort of reservoir for the lubricant
immediately in contact with the working surfaces.
It will be evident that as the moving part travels along the stationary bed of
the machine, any dust or cuttings or turnings which may have fallen on the bed
would be swept away by the rubber scraper, leaving a clean surface which is lubri-
cated by the oil contained in the recess between the lubricator and the face or
end of the moving part of the machine; and besides as a return movement is
made, the oil is swept or carried back by the scraper, thus there is both a reduction
of the wear of the working surfaces and of the amount of oil required for
lubrication whilst both the oil and the wearing surfaces are kept clean and pro-|
tected from dust and particles of metal.
We wish it to be understood that the accompanying drawings are intended as an
illustration merely of our invention, and we do not limit ourselves to the exact
shape nor to the proportious of the parts herein described or shewn, but

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The arrangement of lubricator consisting of a box divided into two parts, the
one for containing the lubricant, and the other furnished with a rubber scraper ;
provided also with passages for allowing the lubricant to pass from the lubricant
reservoir between the rubber scraper and the face or end of the moving part of the
machine, all substantially as and for the purposes herein set forth.
