Improvements in Lubricators for Cycles and other uses.
I, ALFRED VALE, of 93 Stirling Road, Edgbaston, in the City of Birmingham,
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 my improvements, the cup or body part of the lubricator, which
is provided with an externally screwed and hollow shank whereby it is secured in
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
said 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To prevent the cover being withdrawn from the cup, one of the parts carries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
arrangement also constitutes a means for limiting the rotary motion of tho
cover.
Instead of the cover socketting into the inside of the body of the oil cup, it may
take 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.

I, ALFRED VALE, of 93 Stirling Road, Edgbaston, in the City of Birmingham,
Tanufacturer, do hereby declare the nature of this invention and in what manner
[Price 8d.1

page_text: 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 has for its objects, first, a side-feed lubricator,
and secondly, to provide a simple and practically dust-proof cup, having no loose
cap or cover or other parts liable to be dropped and lost.
•
Heretofore cycle and like lubricators have had their oil feed holes or apertures
at the top, and in which position it has been awkward to introduce the oil, and the
spouts of oil cans have had to be bent or cranked in order to facilitate the oiling
operation, but by constructing lubricators with a side feed hole, this disadvantage
is overcome.
Figure 1 of the accompanying drawings represents in front elevation a side-
feed and dust-proof lubricator or oil cup constructed according to my invention,
showing the oil hole in the side of the same open for the feeding of lubricant
into the interior.
Figure 2 is a like front elevation as Figure 1, but with the said oil-hole closed
for the exclusion of dust.
Figure 3 is a side elevation of Figure 1, showing the pin and slot arrangement
by which the component parts are kept together and the turning movement of
the inner part of the lubricator, whereby the oil hole is opened and closed, is
limited.
"
Figure 4 is a vertical section of Figure 2.
Figure 5 represents a horizontal section of the lubricator, taken upon the dotted
line, Figure 1, showing the oil hole open.
Figure 6 is a horizontal section of Figure 2, upon the dotted line ¹, showing
the oil hole closed.
Figure 7 represents the inner and rotating part of the improved lubricator and
Figure 8 represents the fixed body part of the same.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
The cup or body part al, of the improved lubricator a, which is provided with
an externally screwed and hollow shank a³, whereby it is secured into position,
and a facetted or nut shaped collar a³, at the junction of the said stem with the
body, has an oiling hole or gap at, cut within its side a, 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 b, the top edge b', of which is
preferably milled to facilitate its rotation, and its side 2, is pierced with a hole
or opening 3, corresponding in size to the hole a', in the walls of the lubricator
body a', within which the said cap or cover b, is rotatable. When the side
apertures 63, a, 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 2, of its walls opposite to the oil-hole at, in the cup, the said hole is
closed and dust or other foreign matter is excluded.
To prevent the rotatable cover being withdrawn from the cup, the said cover
carries a pin or stud c, working within a slot a, in the body part, which arrange-
ment also constitutes a means for limiting the rotatory motion of the cover.
Instead of the cover socketting into the inside of the body of the oil cup, it may
take 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 slot, depression or groove on the other part, or by suitable equiva-
lent means.
Figure 9 represents an elevation of this modification, and Figure 10 is a
vertical section of the same in which a is the body part with side oil hole a',
and is the outer cap or rotating cover, having an oil hole 3, and being secured
to the said body part, and limited in its rotatory motion thereon, by the stud or
depression c, taking into and working within the slot as, of the said body.

page_text: As a modification of the last arrangement, the fixed and inner body part a,
may carry the stud c, which takes through a slot 65 in the outer rotating cover b,
as represented in Figure 11.
Figure 12 represents another arrangement of side feed lubricator, in which the
inside and movable cover b, is secured to the inner body part a, by an inward stud c,
in the latter, taking into the slot 62, in the former. The stud may either be
rivetted or otherwise secured after the moving part is placed in position within
the fixed body, or before the parts are assembled. In the latter case the slot b³,
would preferably be bayonet-shaped or have a lead 63, as in Figure 13, to pass
over the stud or pin, the said cover being then removably attached, this form of
cap being also applicable to the arrangement of side-feed lubricator shown in
Figure 12, whilst in the other forms (Figures 1 to 10) the slot in the fixed body
part may have a lead extending to the top edge to admit of the cover being
removable.
Instead of cut out or all-through gaps, I may where possible employ in lien
thereof, sinkings or grooves for the studs, or pins to work within.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
First. A dust-proof lubricator or oil cup, comprising a fixed body part, having
an oil-feed hole through its side, preferably covered by a lid, cap or equivalent
closure.
Secondly. A side-feed dust-proof lubricator or oil cup, consisting of a fixed body
or cup, and a movable cover or cap, each having an oil hole or aperture in its
side, adapted to be brought coincident with one another by the rotation of the
movable part within or upon the other, said parts being secured together, and the
rotatory motion of the cover being limited, if required, by a pin or stud on
the one, taking into or engaging into a slot, sinking or groove in the other part.
Thirdly. The improvements in dust-proof lubricator or oil cups for cycles
and other machinery, substantially as herein described and set forth in the
accompanying drawings.
