PROVISIONAL SPECIFICATION.
Improvements in Gear Cases for Bicycles, Tricycles, and the like.
I, CHARLES STAMPER, of 61 Wilmslow Road, Didsbury, in the County of
Chester Tinsmith do hereby declare the nature of this invention to be as
follows:-
•
This invention relates to gear cases, such as are employed for the purposes of
protecting and lubricating the gearing in bicycles, tricycles, and the like; the
object of this invention is to afford a ready means of access for examination or
repairs of the gearing without necessitating the removal of said case after it has
been fitted in position..
I effect this by constructing an opening such as a in Fig. 1, on the accompanying
sheet of drawings, which represents a side view of a gear case as ordinarily
employed.
b
I form a groove around the edge of the aperture a as shown in the sectional
view Fig. 2, in which to slide the edges of a plate a¹ as Fig. 3, of the size and shape
of the aforesaid opening a. The upper part of said plate is semicircular and has a
longitudinal groove & formed thereon.
When the plate is in position over the aperture a, it is securely held and the top
joint covered, by sliding a semicircular cover as c, Fig. 4, along the top of the case
so that the edges c¹ and c of said cover fit into the grooves on cover, and 6* on
the top of case respectively.
In a modification of my invention I form the top of the plate a' so that it will
fit entirely over the top edge of the case and dispense with the cover c.
By these
means when the cover c is withdrawn, the plate a' can be drawn up, and the interior
of the case and its contents exposed to view.
Dated this 1st day of December 1893.

Improvements in Gear Cases for Bicycles, Tricycles, and the like.
I, CHARLES STAMPER, of 61 Wilmslow Road, Didsbury, in the County of
Chester, Tinsmith 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 gear cases such as are employed for the purpose of
protecting the gearing in bicycles, tricycles, and the like from dust and dirt while
travelling, and also to gear cases that are constructed so as to afford in addition
thereto the means for lubricating said gearing.
The object of this invention is to afford a convenient and ready means of access
for examination or repairs of the gearing without necessitating the removal of said
case after it has been fitted in position, or interference with the means that may be
employed in combination with the case for lubricating the gearing. I effect this

page_text: object in the manner hereinafter described and as illustrated in the accompanying
sheet of drawings in which
Fig. 1 represents the side view of a gear case with my invention applied. Fig. 2
is a transverse section of the same drawn through lines A. A. Figs. 3 and 4 are
sectional views of the same drawn to an enlarged scale.
Fig. 5 is the side view of a case with cover to aperture removed.
Figs. 6 and 7 are respectively side and end views of the cover for the
aperture a.
In these views similar letters refer to similar parts.
In the side of a gear case that may be constructed either in the manner that is
described in the Specification of the Patent No. 9283 of 1886 or of other preferred
construction, I form an opening such as a in Fig. 5 on the accompanying drawing
which represents the side view of a gear case as ordinarily employed.
I form a groove around the edge of the aperture a in which to slide the edges
of the plate al as Fig. 6 of the size and shape of the aforesaid aperture a, and
constructed either of metal or other material, or of a transparent substance as xyloite.
The upper part of said plate is semicircular and has a longitudinal groove bl
formed thereon. When the plate a¹ is in position over the aperture a as in Fig. 1
is is securely held, and the top joint covered by sliding a semi-circular cover as c
Fig. 3, along the top of the case so that the edges c' and c³ of said cover fit into
the grooves on the plate a, and 6 on the top of the case respectively.
In a modification of my invention I form the top of the plate a' so that it will
fit entirely over the top edge of the case and dispense with the cover c.
By the means I have herein before described, when the cover c is withdrawn, the
plate a can be drawn up and the interior of the case and its contents exposed
to view.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed i declare that what I
claim is
In a gear case that is employed for the purpose of protecting the gearing in
bicycles, tricycles and the like from dust and dirt, and which may be also con-
structed so as to afford nieans for lubricating said gearing:
1st. The formation of an aperture that may be closed and opened by means of a
covering plate such as a sliding in grooves as b, and secured by a semicircular
cover as c in the manner and for the purpose substantially as herein before
described.
2nd. The use of a covering plate such as a constructed either of metal or other
material, or of a transparent substance, in the manner and for the purpose
substantially as herein before described.
3rd. The use of a covering plate as a' constructed with a semicircular top to fit
over the semicircular top of gear case, in combination with grooves b and the
aperture a¹.
4th. The combination of an aperture as a with a covering plate as a¹, grooves
and cover in the manner and for the purpose substantially as herein before
described.
Dated this 30th day of August 1894.
