FLAUZELLE ROBERTS, OF CENTER, TEXAS.
OIL-CUP FOR WAGON-WHEELS.Specification of Letters Patent. Patented Oct. 23, 19114
Application filed January 8, 1917. Serial No. 141,236.To all whom it may concern:
Be it known that I, FLAUZELLE ROBERTS, a
citizen of the United States, residing at
Center, in the county of Shelby, State of
5 Texas, have invented a new and useful Oil-
Cup for Wagon-Wheels; and I do - hereby,
declare the following to be a full, clear, and
exact description of the invention, such as
will enable others skilled in the art to which
10 it appertains to make and use the same.
The present invention relates to a grease
cup attachment for vehicle wheels, and has
for its object to provide a device of this
character which can be readily applied to
15 the hub of any wagon wheel, and which will
enable the wheel to be lubricated at any time
without the necessity of jacking up the
wheel and removing it from the axle.
Further objects of the invention are to
20 provide a device of this character which is
comparatively simple and inexpensive in its
construction, which can be applied to the
wheel without necessitating any material
changes therein, and which will enable a
25 supply of lubricant to be forced into the
axle boxing and around the axle at any time.
With these and other objects in view, the
invention consists in certain novel combina-
tions and arrangements of the parts as will
30 more fully appear as the description pro-
ceeds, the novel features thereof being
pointed out in the appended claims.
For a full understanding of the invention,
reference is to be had to the following de-
35 scription and accompanying drawing, in
which:-
Figure 1 is a top plan view of a vehicle
hub having a lubricating attachment con-
structed in accordance with the invention
40 and applied thereto.
Fig. 2 is a vertical longitudinal sectional
view through the same.
Fig. 3 is a transverse vertical sectional
view.
45 Corresponding and like parts are referred
to in the following description and indi-
cated in all the views by the same reference
characters.
For the purpose of illustration the in-
50 vention is shown as applied to a wagon
wheel of the conventional construction, in-
cluding a hub 1 and spokes 2, the hub being
provided with an axle boxing 3 and being
mounted upon an axle 4. In carrying out
55 the invention a radial opening 5 is boredin the hub :1 and carrieda part of the way
through the axle boxing 3, the lower end of
the large opening 5 communicating with a
small opening 6 which extends through the
axle boxing and leads to the axle. A feed 60
tube 7 is fitted within the opening 5 and has
the lower end thereof threaded into the
boxing 3. The upper end of the feed tube 7
telescopes within a bushing 8 which is fitted
in the upper end of the opening 5 and which 65
is- internally threaded to receive the stem 9
of a grease cup 10. This bushing 8 is in-
tegral with a plate 11 which is adapted to
fit upon the exterior of the hub 1 and may
be secured thereto by suitable fastening 70
means such as the screws 12. An extension
13 projects upwardly from the inner edge
of the plate 11, and terminates in a spring
arm 14 which engages the milled periphery
of the cap 15 of the oil cup to prevent acci- 75
dental rotation of the cap which might
otherwise be caused by the jars and vibra-
tion when the vehicle is in motion. This
upwardly projecting extension 13 is also
provided with a pair of spoke engaging 80
clamps 16 which are designed to extend
around opposite sides of one of the spokes
2 and to be connected by a clamping bolt 17.
The device is thus held securely in position,
and there is no danger of its working loose 85
and becoming lost. The cap 15 is designed
to be filled with proper grease or lubricant
in the usual manner, and this lubricant can
be fed to the axle through the feed tube 7
at any time when it may become necessary 90
to lubricate the axle, by merely screwing
downwardly upon the cap 15. The wheels
can thus be lubricated when the vehicle is
heavily loaded, without the necessity of
soiling the fingers or jacking up the vehicle 95
to remove the wheels.
Having thus described the invention,
what I claim as new and desire to secure by
Letters Patent, is:-
1. The combination. with a vehicle wheel 100
having a radial opening extending through
the hub and axle boxing thereof, of a plate
fitting against the peripheral surface of the
hub and provided with a bushing project-
ing into the opening of the hub, a grease 105
cup fitted in the bushing, a cap threaded
upon the grease cup, an extension project-
ing from one side of the plate and terminat-
ing in a spring arm which engages the cap
to prevent accidental rotation thereof, and 1101,2439,98.
