Improvements in Means for Securing Movable Screw CoveID
Lubricators and other Vessels.
I THOMAS FLETCHER BRAIME of Rothwell near Leeds, in the County of York,
Engineer do hereby declare the nature of my said invention to be as follows:-
My invention has reference to an improved method of and means for securing,
fastening, or adjusting the screw caps or movable screw covers of oil cups, lubricators,
oil feeders, axles, and other vessels, having movable screw caps or covers.
According to my invention the oil cup, lubricator, oil feeder, axle, or other vessel
having a movable screw cap or cover, has formed at one side in its interior a small
tubular or hollow circular projection, which projection extends from the bottom of the
interior, such a distance as not to interfere with the securing, fastening, or adjusting
of the cap or cover. Within this projection is a spindle having a V shaped or round
head (preferably V); around the said spindle is a coiled spiral or other suitable
spring which bears at the bottom of the tubular projection and against a collar or
projections near the head of the spindle. The said spindle has a slot or oblong hole
through which a pin is passed to prevent the spindle turning round, so keeping it in
combination with the spring in position and so preventing their being lost when the
cap or cover is removed.
On, and around the edge of, that portion below or continued from the threaded,
or screwed, part of the cap or cover, are formed V shaped teeth or projections
which engage with the V shaped head of the spindle aforesaid when the cap or
cover is adjusted.
The spiral spring around the spindle allows the spindle to move up and down to
suit the action of the V shaped head and teeth when the cap or cover is screwed
or unscrewed, thus effectually preventing the cap or cover from being detached or
removed except intentionally, and providing a means by which the cap or cover is
effectually secured or adjusted without the aid of a key, which is usually employed
for such a purpose.

page_text: Further The small tubular or hollow circular projection, instead of being in
the interior, as set forth, may be formed at the outside, with the spindle and
spring arranged as before described; the V shaped teeth or projections being
arranged at the outside of the cap or cover so as to engage with the V shaped head
of the spindle.

page_text: Fig. 10. is an end elevation of axle.
Figs. 11, 12, 13, 134, and 14 are detail views.
According to my invention the oil cup, lubricator, oil feeder, axle or other vessel A
having a movable screw cap or lid B, has formed at one side in its interior a small
tubular or hollow circular projection C, which projection extends from the bottom of
the interior such a distance as not to interfere with the securing and fastening of the
cap or lid.
Within this projection C is a spindle D having a V shaped or round head
(preferably V,) around or at the bottom of the said spindle is a coiled, spiral
or other suitable spring E which bears at the bottom of the tubular projections Cand
against a collar or projections F near the head of the spindle.
The said cup A (or in some cases the tubular projection C) has a slot or oblong hole
through which the pin or finger G of the spindle D projects to prevent the spindle
turning round, and so keep it in contact with the teeth or notches H on the cap or
lid B in position.
The said notches or recesses are on and around the edge of that portion below or
continued from the threaded or screwed part of the cap or lid B and are preferably
V shaped so as to engage with the V shaped head or projecting pin or finger G of the
spindle D aforesaid when the lid or cap
is screwed on.
The spiral spring E around the spindle D allows such spindle to move up and down
to suit the action of the V shaped head and teeth or notches when the lid B is
cap.or
screwed or unscrewed, thus effectually preventing the cap or lid from being detached
or removed except intentionally.
A semi cover J.is also preferably provided so that when the lid or cap B is screwed
on its feed hole K comes over the semi cover J and prevents the lubricant from being
worked out through the feed hole K as shown in Figs. 2 and 3.
The spindle D and teeth or notches H keeping the cap or lid B from working back-
wards so that the oil or lubricant cannot be worked or thrown out through the feed
hole K.
By my improved means the cap or lid B can be effectually secured or fastened, with
the feed hole K over the semi cover J, without the aid of a key, which is usually
employed for such a purpose.
Figs. 4, 5, and show a modification of Figs. 1, 2 and 3. In this modification the
lid or cap B is arrested and locked from the inside, such lid or cover being screwed
into the oil cup and not onto as shown in Fig. 1. The notches or recesses being the
same as in Fig. 1. The slot hole for the projecting pin or finger G being
arranged in the tubular projection C instead of the oil cup or other vessel as shown
in Fig. 1.
Figs. 7 and 8 show my improvements applied to the connecting rod of a
locomotive.
The pipe or tubular projection C is tapped into the connecting rod L, the spindle D
and spring E fitting into such pipe or tubular projection and acting substantially the
same as shown in Fig. 4.
Or instead of tapping the pipe or tubular projection into the connecting rod
as above set forth such tubular projection may be formed by drilling a hole of
the required size into the solid part of the connecting rod as indicated at M in
Fig. 8.
Fig. 9. The tubular projection is in the case of axles formed in the bush, and the
cap or lid B screwed onto the bush as ordinary. When such cap or lid is screwed on
the notches or recesses H engage with the head of the spindle D, and the action
is the same as before set forth.
Instead of forming the notches or recesses and head of the spindle V shaped such
may be formed round if preferred, as shown in Figs. 11 and 12.
Figs. 13 and 134 show V shaped spring N which may be employed in some
cases for engaging with the notches or teeth H so as to lock the cap or lid P,
see Fig. 9.

page_text: Having now particularly described and ascertained the nature of this Iuven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In an oil cup, lubricator, oil feeder, axle, or other oil or liquid lubricant vessel
having the movable screwed cap or lid, the employment of the spring stud or spindle D
engaging with and bearing against the notches or recesses H in the manner and for
the purposes shown and described.
2. In an oil cup, lubricator, oil feeder, axle or other oil or liquid lubricant vessel
having the movable screwed cap or lid, the combination of the screwed lid or cap B,
and recesses or notches H, with the spring E and spindle D, with or without the
tubular projection O, substantially as shown and described.
3. In a connecting rod having a solid lubricator such as Fig. 8, the formation of
the tube or hole M in the solid part of such rod, for the reception of the spring stud
or spindle D, such tube or hole M having a slot for the finger G of the spindle D to
project through, so that the said finger G may engage with the notches or teeth H of
the cap or lid B when such cap or lid is screwed down, substantially as and for the
purposes shown and described.
4. The employment of the V shaped spring N engaging with the notches
or teeth H of the cap or lid P substantially as and for the purposes shown and
described.
