1 WALTER PHILLIPS of Spon Street, Coventry in the County of Warwick, Works
Manager, do hereby declare the nature of this invention to be as follows:-
The present ordinary lubricator spring opens the oil hole by being removed
towards either side working as on a pivot from its attachment (usually a screw) to a
point at a convenient distance on the outer case of the bearing.
My invention attaches the lubricator spring also to the outer case of the bearing
by means of a screw allowing of movement, but in lieu of the lateral action on the
case of the bearing, 1 give it a parallel or up and down action on the case by means
of a slot which allows of its making a slight movement or slide say of or ths of
an inch on the outer case of the bearing and parallel to the sides thereof.
The one end of the spring consists of a proper cover for the oil hole and may be
indented to snap more closely into the oil hole.
The movement as above described opens or closes the oil hole. By preference my
springs are made of hardened and tempered steel.
To prevent the lubricator spring from turning round I fit over the screw-hole a
square piece of steel with a circular cut out the rim to fit in similar indentations to
fix it in the case of the bearing.
Dated this 20th day of December 1888.

COMPLETE SPECIFICATION.
Improvements in Spring Covers for Oil Holes.
I WALTER PHILLIPS, of Spon Street, Coventry, in the county of Warwick, Works
Manager 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 :-
The present ordinary lubricator spring opens the oil hole by being removed towards
either side working as on a pivot from its attachment (usually a screw) to a point at.
a convenient distance on the outer case of the bearing.
My invention attaches the lubricator spring (a) also to the outer case (b) of the
bearing, by means of a screw (c) allowing of movement, but in lieu of the lateral
action on the case of the bearing, I give it a parallel or up & down action on the case
by means of a slot (d) which allows of its making a slight movement or slide say
of or ths of an inch on the outer case of the bearing and parallel to the sides thereof.
The one end of the spring (a) consists of a proper cover for the oil hole (e) and may
be indented (f) to snap more closely into the oil hole (e). The movement as above
described opens or closes the oil hole (e). By preference my springs are made of
hardened & tempered steel.
To prevent the lubricator spring (a) from turning round 1 fit over the screwhole a
square piece of steel (9) with a circular cut out, (h) having indentations (j) to fit in
corresponding indentations on two opposite sides of the screw hole (k) which
indentations prevent the square piece (9) from slipping round. The square piece is as
wide or thereabouts (not wider) as the inside (d) of the lubricator spring (a), so that
when the latter is screwed on it fits on either side of the aforesaid square piece of
steel (g) and the latter thus prevents the lubricator spring (a) from turning laterally
or otherwise than parallel with the sides of the bearing case (b).

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The contrivance made from metal for oil hole covers, having an up and down or
parallel action on the case or bearing.
Dated this Nineteenth day of August 1889.
