Improvements in Gear Cases for Cycles or the like.
We, WILLIAM HENRY HIGGITT, and WALTER CROWSON, both of 104A Great
Hampton Street, in the City of Birmingham, Manufacturers, do hereby declare
the nature of this invention to be as follows:
This invention relates to improvements in the construction and arrangement
of gear cases for cycles and the like and consists as follows:-We make a metal
case or frame, which at the one end encircles the one cog wheel, and at the other
end a hood is hinged or similarly secured, so that when this frame is placed in
position, it may be secured thereto and to cover the other cog wheel. The one
side of the said case is fixed in such frame and is preferably of metal made in
one therewith. The other side is made as follows:-At each end as much metal
is used as permissible but at the large end that part which is immediately near
the wheel hub is made of flexible leather or the like with overlapping joints to
accommodate its being encircled around the hub, such joints being provided with
lacings or other convenient fastenings. The middle portion of the side which
may be termed the side proper is made of a flexible flap whose upper edge is secured
to the longitudinal edge of the frame. Along the bottom edge of this flap is
preferably attached a metal strip which, when in position fits upon the lower
edge of the frame, and is made so as to be fastened to such lower edge. This
may be done in several ways, but one way is to provide upon such strip a number
of studs or projections agreeing with a number of similar studs or projections"
upon the edge of the frame, by means of which the said flap may be laced to
the frame, when the whole is in position. When upon the cycle, the flexible:
side lies upon the inside that is next the frame of the machine. At suitable parts,
upon the interior of the case provision is made for clips by which the case may
be firmly attached to and carried from the bottom fork stay or other part of the
machine frame.

COMPLETE SPECIFICATION.
Improvements in Gear Cases for Cycles or the like.
We WILLIAM HENRY HIGGITT, and WALTER CROWSON, both of 104A Great
Hampton Street, in the City of Birmingham, Manufacturers, 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 the construction and arrangement of
gear cases for cycles and the like and consists as hereinafter described.

page_text: And in order to more clearly describe this our invention we have appended
hereunto an illustrative drawing upon which are figures and numbers of reference,
similar numbers referring throughout to the same thing or part, and in which:-
Fig. 1, is a front view of a gear case constructed according to this our invention
in its closed form.
Fig. 2, shows the said case from the opposite side to that seen in Fig. 1, and
with the flaps and the hood open.
Fig. 3, is an enlarged cross sectional elevation of the case on line A-B Fig. 1.
4, is a metal case or frame, which at the one end encircles the large cog wheel,
and at the other end a hood 5, is hinged or similarly secured and which is pre-
ferably made entirely of metal or other non-flexible material. This hood may be
further secured in its closed position by screw pin 6 or other suitable device,
and so covers the small cog wheel. The one side 7, of the said case is fixed in
such frame and is preferably of metal made in one therewith. The other side
is made as follows: At the large end as much metal is used as permissible as
for instance at 8, but the part 3, which is immediately near the wheel hub is
made of flexible leather or the like with overlapping joints and lacing holes 10,
to accommodate its being encircled around the hub. The middle portion 11, of
the side which may be termed the side proper, is also made of a flexible flap
whose upper edge 12, is secured to the longitudinal edge of the frame 4. Along
the bottom edge 13 of this flap is preferably attached a metal strip 14, which,
when in position fits upon the lower edge of the frame 4, and is made so as to
be fastened to such lower edge. This may be done in several ways but one way
is to provide upon such strip 14, a number of studs or hook like projections 15,
agreeing with a number of similar studs or projections 16, upon the edge of the
frame, by means of which the said flap may be laced to the frame, when the
whole is in position. The lace is not shown. When upon the cycle, the flexible
side lies upon the inside that is next the frame of the machine. At suitable parts
upon the interior of the case provision is made for clips 17, by which the case
may be firmly attached to and carried from the bottom fork stay or other part
of the machine frame.
18, is a cut away slot of usual form to permit of passage of the case over the
crank, which is again closed up by the slide 19.
20, is again a cut away slot of the usual form to permit of the passage of the
case over the back hub spindle which again is similarly closed up by slide 21.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In gear cases for cycles and the like the combination with the metal or
other non-flexible front 7, of the flexible back parts 9 and 11, with their several
complemental fittings.
2. In gear cases for cycles and the like the general combination and arrange-
ment of the parts constituting this our improved gear case substantially as set
forth and shown.
