page_text: I, WILLIAM ROBINSON, of 32 Melton Street, Middlesborough-on-Tees, in 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:-
My invention relates to a construction of lubricators in which lubricant, such as
grease, is used: A part of the lubricator which is arranged to bear against a shaft
or journal to be lubricated is made of woven or finely perforated. material, it may
.be of fine wire gauze, or of canvas. Through this (when the shaft or journal is
rotating) lubricant will pass in sufficient quantity to lubricate it. Such lubricators
may be constructed in various forms according to the requirements of particular
applications.
In one arrangement a reservoir is provided in the form of a cup or box with
a tubular neck, in which is fitted a separate tube open at its upper end, and pro-
vided at its lower end with woven or finely perforated material such as above
referred to, the arrangement being such that this last mentioned end of the tube
can take a bearing against the shaft or journal to be lubricated, thus conveying
lubricant to it from the cup or box which is or may be provided with a suitable
cover.
According to another arrangement, the separate tube is dispensed with. In this
case the cup or reservoir is of a somewhat flattened form in cross section, its lower
end being provided with woven or finely perforated material as above referred to,
and the lubricator being so applied and guided that its woven or finely perforated
end may take a bearing against the shaft or journal to be lubricated.
According to another modification the lubricator is constructed in the form of a
box with a lid, and with one of its sides made of woven or finely perforated
material, and of a contour corresponding to a portion of the circumference of the
shaft or journal to which it is to be applied.
Referring to the accompanying two sheets of illustrative drawings, Fig. 1 shows
in vertical section a lubricator according to my invention.
Fig. 2 is a broken longitudinal section of the separate tube and its woven or
finely perforated cap f to an enlarged scale.
Fig. 3 is a sectional plan of the tube in the line A. B. of Fig. 2.

page_text: Fig. 4 is a longitudinal section (taken in the line C. D. of Fig. 5,) of another
arrangement of my lubricator as above referred to.
Fig. 5 is a sectional plan (taken in the line E. F. of Fig. 4).
Fig. 6 is a plan.
Fig. 7 is a sectional plan in the line G. H. of Fig. 8, and
Fig. 8 is a transverse section in the line I. K. of Fig. 6, of another modification
of my lubricator as above referred to.
Referring to Figs. 1 to 3, a is a cup or box with a tubular neck b and a cover c
hinged at d. e is a tube provided at its lower end with woven or finely perforated
material which forms a cap, and is secured in the example illustrated by a ring g.
The cup or box being charged with lubricant is supported in any suitable manner
as well understood above the shaft or journal to be lubricated, so that the woven
or finely perforated material at the lower end of the tube e rests upon such shaft
or journal, of which a part is represented at h. In the modification illustrated in
Figs. 4 and 5, the separate tube e is dispensed with. a is a box of flattened
tubular cross section constituting the reservoir, and having a woven or finely
perforated bottom f, fastened in any convenient way, such as by soldering, if it be
of metal, but canvas may be employed, as already stated. This form of lubricator
is suitable for bearings of various descriptions. The lubricator is arranged to pass
through and be guided by the bearing to which it is applied, and may be caused
to bear upon the shaft or spindle to be lubricated by the action of its own weight,
assisted or not as desired, by the action of a spring or other convenient means.
Referring to Figs. 6, 7, and 8, the reservoir a is in the form of a box, having
one of its sides f made of woven or, finely perforated material, and of a contour
conforming, or approximately so, to that of the shaft or journal h to be lubricated,
c is a lid hinged at d, and capable of being opened as indicated by dotted lines.
This form of lubricator, when applied at the side of a shaft or bearing may be
kept up to it by a spring or its equivalent. Or the box may be so arranged as to
tend to slide downward against the spindle or shaft under the action of its own
weight, assisted or not as desired, by a spring or its equivalent.
.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner it is to be performed, I declare that what I claim is :-
The improved lubricator substantially as hereinabove described with reference
respectively to and shown in Figs. 1 to 3 inclusive, Figs. 4 and 5, and Figs. 6 to 8
inclusive of the drawings.
