Improvements in Gear Cases for Cycles.
I, HENRY ALLOTT, of Meadow View, Stockport Road, Lower Bredbury, in the
County of Chester, Dyer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in gear cases for cycles the object being
to render same light yet strong and durable, readily attachable and detachable.
To this end I form my improved gear case of woven fabric, say of cotton fabric
or other fibrous material, such as felt stiffened with shellac or the like. The case
is cut from the said stiffened fabric or material in two longitudinal halves and after
having been blocked or worked to the required shape it is varnished or enamelled
to resist atmospheric influences. The said case halves are made to fit over each
other and the upper half is supported at each end by means of bends secured to
the framework of the cycle and covering a portion of the periphery of the chain
wheels, whilst the lower half is secured to the upper half by means of buckles and
straps or other suitable fastenings at each end.
Dated this 5th day of November 1896.

I HENRY ALLOTT, of Meadow View, Stockport Road, Lower Bredbury, in the
County of Chester, Dyer, 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 relates to improvements in gear cases for cycles the object being
to render same light yet strong and durable, readily attachable and detachable.
And in order that my invention may be more fully understoou I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a side view, Fig. 2 a
longitudinal section, Fig. 3 a sectional plan, Fig. 4 an end view of my improved
gear case, and Fig. 5 a cross section of the same at an enlarged scale.
In carrying out my invention I form my improved gear case of woven fabric,
say of cotton fabric or other fibrous material, such as felt, stiffened say with shellac
or the like. The case is cut from the said stiffened fabric or material in two
longitudinal halves a & b and after having been blocked or worked to the required
shape it is varnished or enamelled to resist atmospheric influences. The said case

page_text: halves are made to fit over each other, for instance as shown more particularly
in Fig. 5, by inserting in the top half a a grooved piece of light sheet metal into
which the lower half b fits. The upper half a is supported at each end by means
of bends c & d covering a portion of the periphery of the chain wheels e & f and
secured to an adjacent convenient part of the framework of the cycle, whilst the
lower half 6 is secured to the upper half a at each end by means of buckles g and
straps or other suitable fastenings.
The bends c & d are preferably made of sheet metal with arms c¹ & d' respectively,
their inner ends & d being bent at a right angle and each formed with a hole
which serve to secure the said brackets as hereinafter described. The said arms
are positioned between the inside of the case and the side of the chain wheels, the
bent parts, passing through the axle holes 1, 1 of the case, being placed on
the adjusting screw i, and d by a screw secured to the bearing k of the crank axle.
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 :-
1st. A gear case for cycles cut out of stiffened fabric, blocked or worked to form
two longitudinal halves a & b and afterwards varnished or enamelled, all sub-
stantially as and for the purpose set forth.
2nd. In a gear case formed as specified in the preceding Claim, bends c, c', c³,
d, d, d arranged inside and adapted to support the upper half of the said case,
the lower half 6 being detachably secured to the upper half a, all substantially as
set forth..
