Certain Improvements in Lubricators.
We, JAMES WARD MILLIGAN, of 36, Lancaster Street, in the City of Birming-
ham, Director and Secretary of Perry & Company Limited, and JOHN CLEMENT,
of 36, Lancaster Street, aforesaid, Pencil Maker, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to lubricators of all kinds and particularly to
those which are used on bicycles and other velocipedes and this invention consists
of the herein described improved means for opening and closing the filling hole
in the top or cap of the oil cup of the lubricator.
In one arrangement of carrying out this invention the lubricator cap which is
by preference made flat has a central oil inlet hole and is arranged to turn on the
oil cup as by an annular lip on the inside of the cap being spun or closed over
a bead or projecting edge formed round the top of the cup. Underneath the
cap and fitting in a recess in the top of the oil cup we provide a metal dise in
which is a central oil hole corresponding with the oil hole in the cap. Between
this, disc and the cap there is a thin metal sliding shutter which has a fulcrum
pin near one edge on which the shutter can turn this pin passing through a hole
in the dise and also taking into a, vertical slot in the side of the cup to prevent the
disc from turning. One part of the shutter has a hole corresponding with the
oil hole in the disc, and in the cap and another part of the shutter is blank so
that when the shutter has been turned on its fulcrum this blank part will close
the oil hole in the cover and in the disc. Fixed to the underside of the cap
there is a projection which engages with a slot in the outer end of the shutter so
that when the cap is turned in one direction the said projection engaging with
the slot of the shutter will turn the shutter so that the oil hole therein will correspond
with the hole in the cap and, in the disc and thus the lubricator will be open for
the insertion of oil through the oil hole in the cap; by turning the cap in the
opposite direction the sliding shutter is also turned and slides between the cap
and the disc and closes the oil inlet hole. Thus to open or close the lubricator it
is merely necessary to turn the cap (which is made with a milled head) in the
one or the other direction. The said projection on the inside of the cap which
engages in the slot in the said sliding shutter can readily be made as an inner
projecting part of a metal ring which is soldered or otherwise fixed in the cap.
Instead of the said disc being prevented from turning in the cup by the fulcrum
pin of the sliding shutter passing through the disc and engaging in a vertical
slot in the cup, the, said disc may be otherwise constructed so as to prevent it from
turning in the cup for instead the said disc may be made with two side projections
which take into corresponding cross slots in the top of the lubricator cup.
Instead of the sliding shutter being made to turn on a fulcrum pin to open
and close the oil inlet hole as in the arrangements above described the said sliding
shutter may be made to slide to and fro across the said disc in a slot or groove
formed therein. In this case the said sliding shutter is made somewhat shorter

page_text: than the diameter of the disc and is operated by two curved cam like parts formed
on the interior of the cap and arranged to engage with the ends of the sliding
shutter so that when the said cap is turned in one direction one of the cam like
parts will act on one end of the sliding shutter and move the sliding shutter along
in one direction so that the hole therein will correspond with the oil inlet hole
in the cap and in the disc, and then when the said cap is turned in the opposite
direction the other cam like part of the cap will act upon the other end of the
sliding shutter and move the same in the opposite direction and thus close the
oil inlet hole.
In another arrangement of this invention which is very suitable for cycle pedals
the lubricator is made with a sliding spring cover so arranged that when in its
normal position the sliding cover is by the spring retained over the oil inlet
hole of the lubricator. The front part of the sliding cover is made with a lip
by which the sliding cover can (as by the end of an oil can spout) be pressed
back so as to uncover the oil inlet hole for the admission of the oil from the
oil can and thus when the oil can is removed the spring causes the sliding cover
to slide along, and cover the oil inlet hole. The said sliding cover is by preference
fitted on and arranged to slide along a guide which also forms a lateral extension
at the top of the lubricator, the said sliding cover being made of an inverted
trough section so as to embrace the guide. The said sliding cover is secured in
position by a transverse pin which passes through the sides of the sliding cover
and through a slotted hole in the guide. Fitting in a recess in the guide there
is a coiled wire spring which acts between, the end of the recess and the transverse
pin on the sliding cover and thus moves the sliding cover forward to close the
filling hole as aforesaid.
Instead of making the said cover to slide as in the arrangement last described,
we may hinge the cover at one end to the lateral projecting part of the lubricator
top and so arrange a spring for the cover that when the cover has been turned
down to a certain position the spring will act upon and close the cover down on
to the oil hole, and when the cover has been raised for a certain distance the
said spring will keep the cover turned up in its opened position.

Certain Improvements in Lubricators,
We, JAMES WARD MILLIGAN, of 36, Lancaster Street, in the City of Birming
ham, Director and Secretary of Perry & Company Limited, and JonN CLEMENT,
of 36, Lancaster Street, aforesaid, Pencil, Maker, 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 has reference to lubricators of all kinds and particularly to
those which are used on bicycles and other velocipedes and this invention consists
of the herein described improved means for opening and closing the filling hole
in the top or cap of the oil cup of the lubricator.
.
We will describe this invention by referring to the accompanying drawings on

of the parts on which the lubricator represented by Figs. 7, 8 and 9 is formed;
Fig. 1 is a sectional elevation, Fig. 12 is an end elevation and Fig. 13 is a part

the lubricator being shewn closed in these figs; Fig. 14 is a part sectional plan
of the same lubricator open; Figs. 15 and 16 are sectional elevations of another
form of lubricator constructed according to this invention said lubricator being
represented as closed in Fig. 15 and open in Fig. 16.
We will first describe the arrangement of our invention represented by Figs. 1
to 4 both inclusive, in all of which the same letters of reference indicate the
same parts.
In one arrangement of carrying out this invention see Figs. 1, 2, 3 and 4 the
lubricator cap A which is by preference made flat has a central oil inlet hole a¹
and is arranged to turn on the oil cup B as by an annular lip on the inside of the
cap being spun or closed over a bead or projecting edge formed round the top of
the cup. Underneath the cap A and fitting in a recess in the top of the oil
cup B we provide a metal disc C in which is a central oil hole c¹ corresponding
with the oil hole a¹ in the cap A. Between this disc C and the cap A there is a
thin metal sliding shutter D which has a fulcrum pin near one edge on which the
shutter I can turn this pin d' passing through a hole in the disc C and also
taking into a vertical slot in the side of the cup B to prevent the disc C from
turning. One part of the shutter 1) has a hole corresponding with the oil
hole in the disc C and the hole a¹ in the cap A and another part of the shutter
is blank so that when the shutter has been turned on its fulcrum in one direction
this blank part will close the oil hole a' in the cover A and the oil hole c¹ in
the disc C. Fixed to the underside of the cap A there is a projection ³ which
engages with a slot in the outer end of the shutter D so that when the cap A
is turned in one direction the said projection a³ engaging with the slot d of the
shutter 1) will turn the shutter D so that the oil hole d therein will correspond
with the hole a¹ in the cap A and the hole c¹ in the disc C (see Fig. 2) and thus
the lubricator will be open for the insertion of the oil through the oil hole in the
cap A and which will run out of the lubricator through the outlet &; by turning
the cap A in the opposite direction indicated by the arrow in Fig. 3 the sliding
shutter D is also turned and slides between the cap A and the disc C and closes
the oil inlet holes as represented in Fig. 3. Thus to open or close the lubricator
it is merely necessary to turn the cap A (which may be milled) in the one or the
other direction.
The said projection on the inside of the cap which engages in the slot d'
of the sliding shutter D can readily be made as an inner projecting part a³ of a
metal ring at which is soldered or otherwise fixed in the cap A.
Instead of the said disc C being prevented from turning in the cup B by the
fulcrum pin of the sliding shutter passing through the disc C and engaging in
a vertical slot in the cup B as represented in the arrangement illustrated by
Figs. 1 to 4 both inclusive, the said disc C may be otherwise constructed so as to
prevent it from turning in the cap A, for instance the said disc C may as shewn
in Fig. 5, be made with two side projections which take into corresponding
cross slots in the top of the lubricator cup B.
Instead of the sliding shutter D being made to turn on a fulcrum pin d to
open and close the oil inlet hole as in the arrangement above described the said
sliding shutter may be made to slide to and fro across the disc C in a slot or
groove formed therein. This arrangement of our invention is illustrated by
Figs. 7, 8, 9 and 10. In this case the sliding shutter D is made somewhat

page_text: shorter than the diameter of the disc C and is operated by two curved cam like
parts ele formed in the interior of the cap A' and arranged to engage with the
projections d at the ends of the sliding shutter D as shewn which is made
with parallel sides and is arranged to slide to and fro in the cross groove in the
top of the disc C. When the cap A is turned in one direction as indicated by
the arrow in Fig. 8, one of the cam like parts namely will act on the pro-
jection dat one end of the sliding shutter and move the sliding shutter D along
in one direction that is towards the left hand in Fig. 8 so that the hole in
the shutter will correspond with the oil inlet hole al in the cap A and the corre-
sponding hole c¹ in the disc C, thus the lubricator will be opened as shewn in
Figs. 7 and 8. When the cap A is turned in the opposite direction that is as
indicated by the arrow in Fig. 9 the other cam like part e¹ will act upon the pro-
jection at the other end of the sliding shutter D and move the sliding shutter
in the opposite direction that is towards the right hand in Fig. 8 and thus close
the oil inlet as shewn.
In another arrangement of this invention which is very suitable for cycle
pedals and which is illustrated by Figs. 11, 12, 13 and 14, the lubricator is
made with a sliding spring cover F so arranged that when in its normal position
shewn in Figs. 11, 12 and 13, the sliding cover F is by the spring G retained
over the oil inlet hole of the lubricator cup B. The front part of the sliding
cover F is made with a lip fl by which the sliding cover can (as by the end of an
oil can spout) be pressed back in the direction indicated by the arrow in Figs. 11
and 13 so as to uncover the oil inlet hole for the admission of the oil from the
oil can and thus when the oil can is removed the spring G causes the sliding cover
to slide forward and cover the oil inlet hole. The sliding cover F is by pre-
ference fitted on and arranged to slide along a guide H which forms a lateral
extension at the top of the lubricator the said sliding cover F being made of an
inverted trough section so as to embrace the guide H. The sliding cover is secured in
position by a transverse pin i which passes through the sides ff of the sliding
cover and through slotted holes in the guide H. Fitting in a recess in
the guide H there is a coiled wire spring G which acts between the end 2 of the
recess and the transverse pin i on the sliding cover F and thus moves the sliding
cover forward to close the filling hole of the lubricator as aforesaid.
Instead of making the cover F to slide as in the arrangement last described
and illustrated by Figs. 11, 12, 13 and 14, we may as shewn in Figs. 15 and 16,
hinge the cover F by the pin j¹ at one end of the lateral projecting part H of the
lubricator top and provide the said cover with a spring & so arranged that when
the cover has been turned down to its closed position represented by Fig. 15
the cover will be held in this position by the spring catch of the cover engaging
under the lip of the lubricator top L thus covering the oil inlet to the lubricator
To open the lubricator the small sliding button m at the front of the lubricator
has to be pushed in so as to push in the catch free of the lip h³ and when the
spring turns up the cover F into its open position represented by Fig. 16.
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;-
1. In a lubricator the combination of the oil cup, a disc fitting in the top of
said cup and having an oil hole, a cap also made with an oil hole fitting on and
adapted to turn on said cup, and a sliding shutter arranged between the disc and
the underside of the cap and jointed to the cup at one side and so engaging with
a projection of the cap that when the latter is turned in one direction the sliding
shutter uncovers the oil inlet hole of the lubricator and when the cap is turned
in the opposite direction the sliding shutter closes said oil hole, substantially as
described and illustrated by Figs. 1, 2, 3, 4, 5 and 6 of the accompanying draw-
ings.
2. In a lubricator the combination of the oil cup, a disc fitting in the top of

page_text: said cup and having an oil hole, a cap also made with an oil hole and fitting on
and adapted to turn on said cup, and a shutter arranged to slide in a groove of
said disc and made to take against cam like parts of the cap all so arranged that
when the cap is turned in one direction the sliding cover uncovers the hole of
the lubricator and when the cap is turned in the opposite direction the sliding
shutter closes said oil hole substantially as described and illustrated by Figs. 7, 8, 9
and 10 of the accompanying drawings.
3. In a lubricator the combination of an oil receptacle made with a lateral
extension H at the top, and the sliding spring cover Fembracing and sliding on said
extension, the cross pin i fixed in the sliding cover F and passing through slots ¹
of the extension H, and the spring G contained in the extension H and adapted to
move the sliding cover in the position to close the lubricator, said parts being
constructed and combined together in the manner substantially as described and
illustrated by Figs., 11, 12, 13, and 14 of the accompanying drawings.
4. In a lubricator the combination of an oil receptacle made with the lateral
extension H at the top, the cover F hinged thereto at one end and made to
embrace said extension, a spring in said extension adapted to raise said cover
and means for securing said cover closed and for opening the same, all arranged
and combined together substantially as hereinbefore described and illustrated by
Figs. 15 and 16 of the accompanying drawings.
