An Improved Mount or Spring Cover for Tube Ends.
I WILLIAM CHATER LEA of 21 Great Sutton Street, Clerkenwell London, in
the County of Middlesex do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved mount or spring cover for the open ends of
tubes & tubular forks of all sections as used in the construction of velocipedes in
particular, but is applicable to all tubes for whatever purpose use, and has for
its objects the rapid putting into position & adjustability to variations in the sizes
My improved.
of tubes or tubular forks & security from jarring out of position.
mount is constructed in the following manner. The top, or outer part may be flat
or rounding or any convenient shape or section to match tube end to be covered.
From this top extends two or more legs of any convenient section & curve, made
from an elastic metal or material, the extremities of which are turned inside &
upwards, shaped & meeting in the centre, form a spring by which the legs are
forced outwards against the inner sides of tubes or tubular forks. The extremities
of legs may also be turned ontwards to grip the inner sides of tubes or tubular
forks.
The cover may be made in one or more pieces.

An Improved mount of
1, WILLIAM CHATER Lea, of 21 Great Sutton Street, Clerkenwell, in the
County of London, Manufacturer, 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 caps or covers for closing the open ends of tubes or other
apertures of any section, and comprises the improved means hereinafter described
for holding or fixing the same in position. My improved cap or cover for tube
ends is especially designed for closing the open ends of tubes and tubular forks
used in the frames of velocipedes but is obviously also applicable to tubes used for
any other purposes, or to any other apertures.
In the accompanying drawing
Figures 1 to 4 are top, side, and end views showing one form of my improved
cap or cover intended more especially for closing the ends of oval tubes.
Figure 5 is a view illustrating the method of applying the said cap or cover to
the open end of a tube, the latter being shown partly in vertical section for that
purpose.
Like letters indicate corresponding parts throughout the drawing.
a is the head of the device which when the latter is in position in the tube end
forms the cap or cover for closing the aperture. Firmly secured to or formed on

page_text: the head a, which latter is preferably constructed of a shape to correspond or
approximately to correspond with the transverse section of the tube to which it is
intended to be applied, are legs or projections b. These legs or projections b,
which may be formed of any suitable elastic metal or material, are of a J-shape
the turned-up portions or tails & thereof abutting as shown so as to form strong
springs and the said lower or free ends being normally retained thereby extended
or further apart than the upper ends.
Upon inserting the spring legs or projections & into the open end of the tube to
be closed, the springs will be compressed and the legs or projections become
squeezed together, as shown in Figure 5, so as to firmly retain the cap or cover in
position therein, whilst at the same time admitting of its being readily removed
therefrom when desired.
It is obvious that my improved cap, cover, or tube stopper can be very readily
placed in position, and, moreover, that within certain limits, a device of one size
will be applicable to tubes of varying dimensions.
The lower ends of the legs b may in some instances be advantageously turned or
curved outwardly so as to grip the inner side of the tube or hole. The head a may
be of any desired form, either flat, rounding, and raised and ornamented in any
suitable manner or otherwise, and may be constructed either in one piece or in
several parts as found most convenient.
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 :-
1. A cap, cover, or stopper for closing the open end of a tube or other aperture,
having spring legs or projections which, when compressed and inserted into the said
tube or aperture, will expand therein so as to retain the said cap, cover or stopper
firmly in position substantially as described.
2. The improved cap, cover, or stopper substantially as described and illustrated
in the accompanying drawing.
Dated this 26th day of Mar 1896.
