Improvements in or connected with Oil Holes and Oil Hole Covers,
applicable to Velocipedes and other Machines.
JAMES WILLIAM FLAVELL, of 201 Albert Road Aston, near Birmingham, in
the County of Warwick, Machinist, do hereby declare the nature of this invention
to be as follows:-
My improvements consist in forming a spring clip which fastens round the barrell
of a cycle hub, in the said clip, I make or form a conical hole, the cone of which
takes into a hole in the hub barrell. On the said clip I raise or form one or more
ears or projections, hinged to which is a spring lid or cover, having a corre-
spondingly conical or other shaped projection which fits into the conical hole in the
spring clip. Instead of employing a spring clip, I may use a spring metal piece or
body, for the before mentioned lid or cover to be hinged or fastened to, in which
case I fasten the said spring metal piece or body to the barrell of the hub or any
other convenient part, by a hollow screw through which the oil passes in the
ordinary manner. By this method they may be attached to any article requiring
lubrication.

COMPLETE SPECIFICATION.
Improvements in or connected with Oil Holes and Oil Hole Covers,
applicable to Velocipedes and other Machines.
I JAMES WILLIAM FLAVELL, of 201, Albert Road, Aston, near Birmingham
in the County of Warwick, 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 :-
This invention has reference to oil hole covers for velocipedes and other purposes.
In order that my invention may be clearly understood I have annexed the
accompanying sheet of drawings which illustrates same.
Fig. 1 is plan view of an oil hole cover in a closed position constructed according
to my invention. A is the spring clip which clips around the barrel of the hub B.
In the centre of the said clip A. I form a conical hole a (or I may insert a conical
cup) through which the lubricant passes, which takes into the ordinary oil hole
formed in the said hub barrel B. Raised or formed out of the extended portion b
of the said clip A are two ears or projections c, hinged to which is the lid or cover d
having a conical projection which fits into the conical hole a formed in the spring
clip A. A suitable spring e is provided for keeping the lid or cover d firmley on
its seating.
At Fig. 2 I have shewn a different method of constructing the oil hole_cover.
In this case I form the lid or cover d so that it follows the same plane or radius as
the spring clip A.
Fig. 3 shews another method for keeping the lid or cover d on its seating without
the use of the spring e.
On the end of the said lid or cover d I form two or more
ears which are hinged to the spring clip A. The said ears fextend below the
inner surface of the said clip A so that they bear upon the barrel of the hub or

page_text: other article to which the oil hole cover is attached, by which means the said lid
or cover is firmly held on its seating.
Fig. 4 shews another method of constructing the oil hole cover. Instead of
forming the part C so as to clip the barrel of the hub, shewn in dotted lines at B
I secure the said part C to the said barrel B by means of the cupped hollow
screw D or equivalent and construct the lid or cover d in any of the different
methods as above described. The lubricant passes through the hole in the said
screw D. It will easily be understood that the method of constructing oil hole
covers as described and shewn at Fig. 4 can readily be applied to any other article
or machine which requires lubricating and where it is necessary to keep the dust
and dirt from entering through the lubricating hole. Instead of the lid or cover d
being hinged in the manner as above described and shewn on the drawings it may
be hinged so as to move in the same horizontal plane as the body portion of the
said oil hole cover.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would have it under-
stood that I do not confine myself to the precise details of construction as herein
shewn and described as they may be varied without departing from the nature of
my invention, but what I wish to claim is :-
Firstly. In a spring clip oil hole cover providing the same with a lid in the
manner substantially as herein shewn and described with reference to Fig. 1.
Secondly. Providing a spring clip oil hole cover with a lid in the manner
substantially as herein shewn and described with reference to Figs. 2 and 3.
Thirdly. The method of attaching oil hole covers substantially as described
and shewn at Fig. 4 in combination with a cup or hollow screw or equivalent.
Fourthly. Oil hole covers substantially as herein shewn and described.
Dated this 3rd day of August 1894.
