Hartford, Connecticut, United States of America, Superintendent of Tool
Making.]
We, JOHN JAMES HENRY STURMEY, Journalist, and WILLIAM ISAAC ILIFFE, Printer'
both of 19 Hertford Street, Coventry, Warwickshire, 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:-
.
Our invention relates to oil cups such as are commonly fitted to velocipedes and
other machinery, and has for its object to provide an oil cup so constructed as to
embody in the fewest possible number of pieces a device capable of ready attachment
to a machine or a part thereof without injury to the oil cup, and one that shall be
durable and efficient in use as well as simple and cheap in construction.
And in order that our invention may be readily understood and carried into effect
we will describe the saine with reference to the accompanying drawings, wherein
corresponding parts are marked with the same letters of reference.
Figure I is a view in side elevation of our improved oil cup.
Figure II is a detail side view of the inner or fixed member, and of the outer
member in section, before the parts are secured together.
Figure III is a detail top view of the device with parts arranged as shown in
Figure 2.
Figure IV is a view in vertical central section through the cup.
The fixed member a of the oil cup is hollow so as to provide free passage for the oil
and has through its side wall a port or opening a¹ through which the oil may be
introduced. The outer end of this fixed member is solid so as to form a head to
receive blows by means of which the said fixed member may be driven tight into a
hole in the machine or part of the machine to which the oil cup is to be secured.
The head may, if desired, be provided with a slot 6¹ to receive the point of a screw-
driver by which this member may be screwed into a threaded hole, or the head may
be squared to receive a wrench for the purpose of screwing it into place.
The outer surface of the fixed member a is provided with a locking shoulder c
preferably angular in outline of cross-section, and this forms the means by which the
rotary member is held against lengthwise movement on the fixed member a while
being left free to rotate in sliding contact therewith.
The outer member d is a sleeve fitting snugly on the outer surface of the fixed

page_text: member so as to make a practically dust proof contact and yet leaving the parts free
to turn on each other except for the frictional resistance to rotation needed to
prevent the accidental movements of the parts one on the other.
This movable member or cap d of the oil cup is enlarged at one end, and
counterbored leaving a comparatively thin lip d', which projects beyond an inner
shoulder adapted to fit against the shoulder c on the fixed member.
The lip
d¹ of the outer member is turned down upon the locking shoulder in any con-
venient manner, the parts binding on each other, with a frictional grasp which
may be aided by making the annular lip flexible in any convenient manner.
The oil-hole ³ through the outer member is so located as to register with the
hole a in the inner member when the parts are turned into proper position. In
order to close the passage, the sleeve or cap d is moved around on the fixed
member a a sufficient distance to throw the openings d³, a¹ out of register.
The oil cup as thus constructed consists of but two pieces, the fixed member a
and the movable member d, the devices for uniting the parts so as to permit
the rotary movement of one on the other being appurtenant to the respective
parts, and the means for attachment are simple and involve merely the bending
of a portion of one part over a locking shoulder on the other. The main feature
of the improvement resides in that feature of the construction which enables the
oil cup as a whole to be secured in place on a machine by driving it firmly into
a hole therein, or by screwing it into place when such method of attachment is
preferred. The oil cup as a whole is assembled and ready for use when put upon
the market and is so simple in construction and positive in the means for uniting
the two parts as to provide an extremely durable device which by the closeness of the
fit of the moving parts is dust proof and sufficiently tight to prevent the leaking of
oil. Another feature of the improvement resides in the means of securing the
sleeve or movable member on the fixed member without regard to the particular
construction of either end of the fixed member.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed we declare that we are aware that oil
cups have already been constructed in two parts capable of relative rotation so that
holes in each may be made to register or not according as it is desired to open or
close the passage for the introduction of the lubricant into the oil cup, and we do not
claim such construction broadly, but what we do claim is :-
1. In an oil cup, the combination of a fixed member having an internal locking
shoulder and an oil port, a rotary member formed by a sleeve held in sliding contact
with the fixed member by a lip on the sleeve turned down upon the outer surface of
the locking shoulder, the said sleeve terminating short of the ends of the inner
meinber, and the oil-hole in the outer member or sleeve adapted to register with that
in the inner member, all substantially and for the purpose set forth.
2. In an oil cup, the combination of an inner member having a locking shoulder
and an oil port and its outer end adapted to receive a tool for securing the fixed
member in place, a rotary member formed by a sleeve held against lengthwise
movement on the fixed or inner member and free to rotate thereon, each end of the
outer member terminating short of each end of the inner member, and an oil hole in
the outer member adapted to register with the oil hole in the inner member,
substantially as described.
3. In an oil cup, the combination of an inner member having a locking shoulder
and an oil port and with its outer end adapted to receive a tool for securing the fixed
member in place, a rotary member formed by a sleeve with a socket having one wall
.consisting of a lip turned down upon the locking shoulder and whereby the two parts
are held against relative lengthwise movement, each end of the outer member
terminating short of each end of the inner member, and the oil hole in the outer
member adapted to register with the oil hole in the outer member adapted to register
with the on hole in the inner member, substantially as described,

page_text: 4. The improved oil cup substantially as herein described with reference to the
accompanying drawings.
