Improvements in Oil Cups.
I, JAMES MACPHAIL, of Blue Island, County of Cook, and State of Illinois,
United States of America, Mechanical Engineer, 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: -
My invention relates to an improved and useful oil cup for bearings, and is
intended to produce an oil cup that can be cheaply manufactured, and that will
be durable in its construction, effective in operation, and incapable of getting out
of order. My improved oil cup is intended primarily for use on farming imple-
ments, but it will be understood that it can be used wherever bearings are to be
oiled.
Fig. 1 is a plan view of my improved oil cup.
Fig. 2 is a section of the same on the line 2-2 of Fig. 1.
Fig. 3 is a similar section with the cover elevated to permit of the insertion of
the oil.
Fig. 4 is a plan view similar to Fig. 1 but with the cover and the spring
removed.
Fig. 5 is a front elevation of the cover.
Fig. 6 is a side elevation of the cover, and
Fig. 7 is a rear elevation of the cover.
In the drawings, A represents a portion of a cylindrical casting forming a portion
of the bearing for a shaft, and B is the oil cup proper which may be cast with
the part A. On its outside the cup B may be of a cylindrical shape, and its
interior surface may have the same general shape. An aperture D leads from the
oil cup to the bearing for the purpose of permitting the oil in the cup to reach
the bearing.
In order to protect the cup from dirt I provide a cap or cover G which consists
of a flat plate having the outline shown in Fig. 1, and having the wing K pro-
jecting therefrom at substantially right angles thereto. This wing K projects
into the interior of the cup B and has a concave bearing surface H which engages
with the convex bearing surface E which forms one edge of the aperture C
forming the top of the cup. Projecting forwardly from the wing K is a lug L,
which is opposed in position to a lug F which projects rearwardly and downwardly
from the upper portion of the inner front wall of the cup B. A helical spring Mis
interposed between said lugs F and L, and it will be seen from an inspection of
Figs. 2 and 3 that the action of this spring M co-operating with the lugs F and L
is to hold the cover G firmly down upon the top of the cup B and prevent any
dust or dirt from entering said cup. When one edge of the cover is lifted to the
position shown in Fig. 3, the spring M is put under increased tension and im-
mediately returns the cover G to its normal position as soon as it is released.
pair of ribs J are located on the under side of the plate or cover G and serve to
strengthen said cover and to assist in holding the cover in its correct position, as
A

page_text: when the cover is down, the ends of the ribs J are substantially against the front
edge and sides of the aperture C. For convenience in raising the cover I form a
portion N of the cover G which overlaps the cup B as clearly shown in Fig. 2
and forms a projection to be grasped in raising said cover.
The two principal parts of this oil cup are cast, and they with the spring M,
constructed and combined as shown, furnish a dust proof cup that can be cheaply
constructed and cannot readily get out of order.
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
1. An oil cup consisting of the cup proper having an aperture, and a pivotal
bearing surface on one edge of said aperture, with the cover having a pivotal
bearing surface co-operating with said other bearing surface, and a spring inter-
posed between said cup and said cover to hold it normally closed, substantially as
described.
2. An oil cup comprising the cup B having the pivotal bearing surface E and
the lug F, with the cover having the bearing surface H and the lug L, and the
spring M interposed between said lugs.
3. An oil cup comprising the cup proper having the pivotal bearing surface
and the lug F, with the cover having the lug L, and the overlapping portion N,
and the spring interposed between said lugs, substantially as described.
4. The oil cup comprising the cup B having the aperture C, the bearing surface E,
and the lug F, with the cover G having the bearing surface H, the ribs J, and the
lug L, and the spring M, all co-operating, substantially as and for the purposes
described.
5. An oil cup comprising the cup proper having an aperture, said apertura
having a pivotal bearing surface on one edge thereof, with the cover for said
aperture having a pivotal bearing surface on one side thereof co-operating with
said other bearing surface, an arm projecting into said cup, and a spring in said
cup interposed between said arm and cup to hold the bearing surfaces in contact
and the cover closed, substantially as described.
