A New or Improved Means of Fixing Pneumatic Tyres to. Hollow
or Solid Rims.
I, ERNEST PHILIP CLARKE, 124, Holland Park Avenue, Notting Hill, London,
Bicycle Maker, 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 a new or improved means for fixing pneumatic
tyres to hollow or solid rims.
Referring to the annexed drawings which are copies of those filed with my
Provisional Application,
Figure 1, is a cross section of the outer cover constructed according to my
invention,
Figure 2, cross section of locking band.
Figure 3, cross section shewing the outer cover secured to a rim.
The outer cover O which may be made of any suitable material is provided
with thickened edges A. so arranged that the part A¹ will engage in the grooves
or recesses D in the rim E which may be of wood or metal or other material,
as may be most convenient. The locking band F may be made of any suitable
material, such as canvas and rubber and is provided with the projecting edges B
Din B.17

page_text: which, when the cover is in position upon the rim, engage upon the projecting
parts A of the cover C; the band Fencircling the edges of the cover.
G is a
wire or the like which passes around the outside band F and maintains it in
position. By this arrangement it will be seen that the cover is securely held
in the rim, and at the same time one edge of the cover may be readily removed
by deflating the air tube.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In means for fixing pneumatic tyres to solid or hollow rims: the com-
bined construction and arrangement of the various parts substantially as herrin
described and illustrated and for the purpose set forth.
2. In means for securing pneumatic tyres to velocipede wheels and the like;
a cover having enlarged or thickened edges so arranged and adapted that one
part of the enlarged or thickened edges engages in grooves in the rim, the other
projecting edges in the interior of the cover engaging with projections or
depending edges upon a band of suitable material which encircles the inner edges
of the cover; a wire or the like which encircles the said locking band for the
purpose of keeping the whole in position, substantially as described and illus-
trated herein.
