PROVISIONAL SPECIFICATION.
Improvements in and relating to Gear Cases or Covers for Cycles.
We, DAVID ROSE, of 73, Glover's Road, Small Heath, Birmingham, Gear Case
Manufacturer, and CHARLES GOULD, of 62, Herbert Road, Small Heath, Birming-
ham, Gear Case Manufacturer, trading as Rose, Gould & Co., of 14, Bath Street,
Birmingham aforesaid, do hereby declare the nature of this invention to be as
follows:-
This invention consists in forming a metal skeleton frame having the rear end
enclosed with metal, that is to say this rear end is made with metal sides a certain
distance which covers in the rear wheel hub and chain, the skeleton frame of
the case is a continuation of the metal end being attached thereto by a screw or by
a lubricator which in the latter case answers the purpose of a screw, or other
suitable means of connection may be employed.
The metal frame is enclosed by a covering of leather or other suitable material
which may have a panel on either side of celluloid which covering is only neces-
sary over the skeleton part of the case and not at the closed in end and which thus
completes the covering in so forming the case.
By this method it becomes a much easier matter to fit the case than the ordinary
leather gear cases and furthermore it enables us to have the adjustment plates
(that box in the rear axle) upon the metal end which obviously cannot be employed
on the leather gear cases now in use. A further advantage is that we are able
to dispense with one of the vertical stays and clips which the ordinary leather
cases require, as by our arrangement the metal end acts in lieu of the second
stay & clip.
By our improvements we are able to make a more substantial case and also more
dust proof and rigid and one that can be much more readily fitted on to the machine
than the usual leather ones.

Improvements in and relating to Gear Cases or Covers for Cycles.
We, DAVID ROSE, of 73, Glover's Road, Small Heath, Birmingham, Gear Case
Manufacturer, and CHARLES GOULD, of 62, Herbert Road, Small Heath, Birming-
ham, Gear Case Manufacturer, trading as Rose, Gould & Co., of Birmingham
aforesaid, 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 reference being had to the sheet of drawings accompanying
this specification and to the figures and letters shewn thereon.
Figure 1 shews the case or cover complete in elevation. Figure 2 renresenta

page_text: an edge view of same. Figure 3 is an elevation of the skeleton frame and metal
end forming the foundation of the case or cover. Figure 4 is an alternative
method.
Our invention consists in forming a metal skeleton frame A having the rear
end B enclosed with metal, that is to say this rear end B is constructed with
metal sides B₁ a certain distance which cover in the rear wheel hub and chain
at that part. The skeletou frame A of the case is a continuation of the metal
end B and made in one therewith or suitably connected thereto by soldering or
by a screw or by a lubricator which in the latter case answers the purpose of a
screw or other suitable means of connection may be employed. Preferably the
skeleton frame A will be permanently attached to the metal end B by soldering
or by being made integral therewith. The frame A will be fastened at the chain
wheel end by a screw C or other suitable means.
Or the metal end B and skeleton frame A may be of this form shewn in Figure 4
and made to open at the rear part by being divided as at D and secured by a
screw Cor lubricator. The metal frame A is enclosed by a covering of leather F
or other suitable material and which may have a panel G in either side of celluloid,
the leather covering F is only necessary over the skeleton part or frame A of the
case and not at the closed in metal end B which thus completes the covering so
forming the gear case.
The leather covering F will be attached on the edge of the skeleton frame by
means of hooks and laces H H¹ or other approved method of connecting the
meeting edges of the leather covering F.
By the above described method of constructing a gear case it becomes a much
easier matter to fit the case than the ordinary leather gear cases and furthermore it
enables us to have the adjustment plates, slides, or clips J (that box in the rear
wheel axle) upon the metal end 13 which obviously cannot be applied on the leather
gear cases now in use. A further advantage is that we are able to dispense with
one of the vertical stays and clips which the ordinary leather cases require, as by
our arrangement the metal end B acts in lieu of the second stay and clip, (the
one stay is shewn at K).
By our improvements we are able to make a more substantial and rigid case
of this kind than hitherto and also dust and weather proof and which can be
much more readily fitted on to the machine than the usual leather ones.
Modifications as to details may be made to suit different requirements without
departing from the essential features in connection with our invention.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
Firstly. A gear case constructed and arranged in the manner substantially as
described and illustrated in the drawings.
Secondly. In gear cases the construction and arrangement consisting of the
skeleton frame A formed integral with or attached to the metal end B, said skeleton
frame having a cover of leather or other material suitably attached thereto said
metal end B being formed to receive the clips and slides for boxing in the gearing
all operating in combination as and for the purpose described and illustrated.
Thirdly. Arranging a gear case with a metal end and sides B B in combination
with a metal skeleton frame A as described and illustrated.
