An Improved Detachable Protector or Guard for the Frame Tubes
of Cycles.
I, CHARLES EDWIN CORBITT, of 57, Market Street, Chorley, in the County of
Lancaster, Ironmonger, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention has for its object, an improved detachable protector or guard
which is made of celluloid, rubber or any suitable material for the frames or tubes
of cycles whereby the enamel upon the tubes is protected from being scratched
or knocked off by the feet of the rider or by the luggage.
In order that my invention may be easily understood I have appended hereunto
a sheet of drawings upon which :-
Figure 1 is a view of a part of the frame of a ladies cycle with my invention
applied thereto.
Figure 2 is a similar view of a gentlemens cycles.
Figure 3 is a cross section on line 1-2 on an enlarged scale.
Figure 4 is a similar section on line 3-4 and Figure 5 on line 5-6.
Figure 6 is a broken off longitudinal section of the cover or protector.
Figure 7 being a cross section of the cover.
One mode of making my cover A is to cut a strip say of celluloid or other suit-
able material and bend it to a half round or crescent shape as shown in the section

page_text: Figure 7 this strip is then twisted in a spiral form so as to clip upon the top down
tube B of a ladies cycle as seen in Figure 1 the corrugations 6¹ formed by the
bending of the strip giving it greater strength & durability.
Instead of the strip being twisted into a spiral form as described it could be
simply attached to the tubes by means of springs or clips.
Another mode of making the cover A would be to simply take a flat piece of
celluloid or other suitable material and twist it into a spiral form as seen in
Figure 2 attached to the bottom frame tube C of a gentlemans cycle and in the
section Figure 4 or instead of it being twisted in a spiral form it could be simply
bent in a half round form as seen in Figure 5 so as to clip round a tube as shown
in this figure or as shown in Figure 2 where the protector or cover A is attached to
the top tube D of a gentlemans cycle by the clips d¹.
Any of the foregoing shapes of my protector or cover can be adapted to any
parts of cycles which are required to be so protected and can be made of celluloid
rubber or other such suitable material.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, what I claim is:
1st. A new or improved detachable protector, guard or cover for the frame tubes
of cycles made corrugated and in the manner described in the foregoing specifica-
tion and shown on the accompanying drawings.
2nd. A new or improved detachable protector, guard or cover for the frame
tubes of cycles made from a flat strip or strips and in the manner described in the
foregoing specification and as shown on the accompanying drawings..
Dated this 1st day of March 1898.
CHARLES EDWIN CORBITT..
