Improvements in Lubricators for Cycles and other uses.
We, WILLIAM EDWARD HOLLIS of Conway House, Woodend Road, Erdington
near the City of Birmingham, Manufacturer, and WILLIAM JOHN CROSS, of 101
Mott Street, Birmingham aforesaid, Manufacturer, and ALFRED VALE of 93 Stirling
Road, Edgbaston, Birmingham aforesaid, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to lubricators or oil cups employed in connection with
the bearings of cycles and machinery generally for facilitating the feeding of
lubricating oil to the same, and has for its object, a simple and practically dust-
proof cup, having no loose cap or cover or other parts liable to be dropped and
lost.
According to our improvements, the cup or body part of the lubricator, which
is provided with an externally screwed and hollow shank whereby it is secured
into position, and a facetted or nut shaped collar at the junction of the stem and
body, has an oiling hole or gap cut within its side through which the spout of
an oil can is introduced when oil is being supplied, whilst socketting into the
inside of the said cup is a cap or cover, the top edge of which is preferably milled
to facilitate its rotation and its side is pierced with a hole or opening corresponding
in size to that in the walls of the lubricator body within which the cap or cover
is rotatable. When the apertures in both cup and cover are coincident, oil can
be introduced into the lubricator, but on the cover being rotated to an extent
sufficient to bring a solid part of its walls opposite to the oil-hole in the cup, the
Baid hole is closed and dust or other foreign matter is excluded.
To prevent the cover being withdrawn from the cup, one of the parts carries a
pin or stud working within a slot or depression in the other part, which arrange-
ment also constitutes a means for limiting the rotary motion of the cover.
Instead of the cover socketting into the inside of the body of the oil cup, it may
tako upon the outside of the same its removal being prevented and the extent of
its rotation being limited by a pin or stud on the inside walls of the outer part
engaging in a depression or groove on the other part, or by suitable equivalent
means.
The arrangement for limiting the rotatory motion of the cover may be effected
by forming a sunken channel or groove in the walls of the one part, and forming
a pin or stud by impressing or indenting inwards a part of the walls of the
other portion of the lubricator, or the stud, made by indenting inwards the metal
of the walls of the cover, may take into a cut out groove or pierced slot in the
body of the oil cup.
To facilitate the rotation of the cover, we propose to provide the top edge or lid
of the same with a series of equidistant or other outstanding small projections,
studs or horns, over one of which the hole in the end of an oil can pipe, may take,
or against which the end of the pipe may come so as to push round the cover and
give the requisite part turn to the same or we may employ two or more oppositely

page_text: or conveniently disposed upstanding projections, arms or horns either alone or
in conjunction with a series of radial studs, or a small upright loop or eye of any
suitable shape may be directed from any part of the cover wherethrough the end
of the oil can pipe may take for turning the lid.
The latter part of our improvements are applicable to other forms of lubricators,
besides those such as described in which the feeding is offected from the side.

We, WILLIAM EDWARD HOLLIS of Conway House, Woodend Road, Erdington
near the City of Birmingham, Manufacturer, and WILLIAM JOHN CROSS, of 101
Mott Street, Birmingham aforesaid, Manufacturer, and ALFRED VALE of 93 Stirling
Road, Edgbaston, Birmingham aforesaid, Manufacturer, 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 lubricators or oil cups employed in connection with
the bearings of cycles and machinery generally for facilitating the feeding of
lubricating oil to the same, and is in part an improvement upon the invention
described in the specification of Letters Patent granted to Alfred Vale (one of the
present applicants) and dated the 15th day of January 1897 and numbered 1088.
The objects of the present improvements are first, to simplify the method of
connecting together the component parts of such fubricators and secondly to
facilitate the rotation of the cover, cap or lid of the same to open or close the oiling
aperture.
Figure 1 of the accompanying drawing represents a side-feed lubricator, of the
type described in the said Specification of Letters Patent No. 1088 and having the
movable cap secured to fixed body or cup according to the first part of the present
invention.
Figure 2 is a part vertical section of Figure 1.
Figure 3 is a horizontal section of Figure 2 upon the dotted line .r.
Figure represents the fixed body part separately, and
Figure 5 a like view of the movable element or cover.
The same letters of reference indicate corresponding parts in the said Figures 1
to 5.
a is the cup or fixed body part of the lubricator, having an ciling hole or gap a', 4
cut within its side through which the spout of an oil can is introduced when oil
is being supplied, whilst socketting over the said cup is a cap or cover b, or hole
or opening 6', corresponding to that in the walls of the lubricator body.
To prevent the cover being withdrawn from the cup, one of the parts carries a
pin or stud working within a slot or depression.

The arangement for securing together the component parts of the oil cup, and
also if necessary, for limiting the rotatory motion of the cover is effected by
forming a sunken channel or groove, in the walls of the cup part, and forming
a stud, by impressing or indenting inwards a part of the walls of the cover
portion of the lubricator, or the stud 6³, made by indenting inwards the metal of 5

page_text: the walls of the cover, may take into a cut out groove or pierced slot a³, in the
body of the oil cup, as represented in vertical section in Figure 6 and horizontal
section in Figure 7.
Instead of the indented stud being formed upon the cover and the groove or
slot upon the cap, the walls of the former may be grooved, channelled or gapped
to receive an indentation or bulged stud made on the outer periphery of the latter.
To facilitate the rotation of the cover, we propose to provide the top, edge or
other suitable part of the lid of the same with two, or a series of, equidistant or
other outstanding small projections, studs or horns, over one of which the hole in
the end of an oil can pipe may take, or against which the end of the pipe may come
so as to push round the cover and give the requisite part turn to the same or we
may employ two or more oppositely or conveniently disposed upstanding siukings,
projections, arms or horns either alone, or in conjunction with a series of radial
studs, or a small upright loop or eye of any suitable shape may be directed from
any part of the cover wherethrough the end of the oil can pipe may take for
turning the lid.
Figure 8 represents a side elevation of a lubricator the lid of which is provided
or formed according to one form of this part of our invention and Figure 9 is n
plan of the same.
In this form, the edge a¹, of the lid a, is provided with a series of equidistant
studs or projections c, against or between which the pipe of the oil can may be
brought to bear to rotate the cover.
Or said cover may only have a pair of opposite studs c, on its edge, as represented
in plan in Figure 10.
Figure 11 represents a plan of another form of lid, in which the edge a', has a
number of separated gaps a³, formed in it to constitute engagements for the oil
can pipe, or only a pair of such gaps a³, may be provided as in the arrangement
shown in plan in Figure 12.
Figure 13 represents an elevation, and Figure 14 a plan of another modification,
in which a pair of upstanding studs a³, are disposed on opposite sides of the cover,
and Figure 16 is a plan of an arrangement having four such studs a³, equidistantly
set around the edge of the cover. Or the studs which can be of any shape may be
disposed in any number, and in pairs or otherwise, at the edges or in other
positions upon the top of the lid, so long as they form an efficiout engagement
for the stem of an oil can or other small instrument in rotating the cover.
Figure 16 is an elevation of a lubricator, the edge b', of the cover b, of which
is provided with sinkings or interspaced holes 63, to receive the end of the pipe,
whilst
Figure 17 represents another form in which a pair of similar depressions or
holes 6, are formed in the top b', of the lid b.
In the arrangement shown in side elevation in Figure 18 and in plan in
Figure 19, the same object is arrived at by providing a small loop b, of suitable
size across the top b', of the lid.
Figure 20 is a modification of the last form, in which two such loops b³, are
arranged crosswise, although they may be disposed in a parallel pair, either at
the middle of the cap or at opposite or other parts of the sides.
Or a single curved and upstanding loop, may be situated near the top edge i³,
of the said lid b, as represented in Figure 21, or it may project outwardly from
the said edge as shown in the plan of the lid Figure 22. Two or more loops
similar to those represented in Figures 21 and 22 may be disposed in suitable
positions around the top or at the edges of the said cover or lid, and further, if
required, any two or more of the said several forms of rotating engagements may
be combined in or provided upon a single lid or lubricator cover.
Parts of our improvements are applicable to other forms of lubricators besides
hose such as described and represented, in which the feeding is effected from
the side.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
First. Iu lubricators or oil-oups of the kind herein described, securing the
movable cap or cover in position upon the fixed body or cup, and forming a stop
for limiting the motion of the movable part relative to the other, by making a
small indentation, bulging or depression on the one part taking into a depression,
groove or gap in the other part, substantially as described and set forth.
Secondly. In lubricators or oil cups having rotating or movable covers, caps,
lids or closures, providing or forming upon the same with outstanding projections,
studs or equivalents, or with sinkings or depressions, or with loops or equivalent,
constituting an engagement for the spout of an oil-cau or other small instrument
in rotating the said movable cover or the like for opening or closing the oiling
aperture, substantially as described and set forth.
Thirdly. The improvements in lubricators or dust-caps for cycles and other
machinery, substantially as described and set forth.
