PROVISIONAL SPECIFICATION.
Improvements in Rims or Tyres for Wheels of Bicycles, Tricycles,
and other Vehicles.
I JAMES HUDSON of Tennant Street Birmingham in the County of Warwick, Tube
Manufacturer do hereby declare the nature of the said invention for IMPROVEMENTS IN'
RIMS OR TYRES FOR WHEELS OF BICYCLES TRICYCLES AND OTHER VEHICLES to be as
follows:-
My invention relates to rims or tyres for wheels to be used in those kinds of
vehicles described in the title and it is an improvement upon the patents No. 64-1885
and No. 4675 1885 granted to me. Hitherto these tyres have been constructed either
from plain sheet steel or other metal having a thickened bottom; or from plain sheet
steel or other metal corrugated in the course of its manufacture. But in my improved
invention I construct a rim which shall be suitably corrugated in section, but drawn
from sheet metal having a thickening or swelling in its centre. This thickening is
drawn into the corrugation on the under side of the rim and it is found that great
sirengil is added to that part of the rim through which the apertures to receive the
spokes are drilled or pierced.

AL
Hitherto these tyres have been constructed either from plain sheet steel or other
metal having a thickened bottom; or from plain sheet steel or other metal corrugated
in the course of its manufacture. But in my improved invention I construct a rim
which shall be suitably corrugated in section but drawn from sheet metal having
thickening or swelling in its centre this thickening is drawn into the corrugation on
the under side of the rim and it is found that great strength is added to that part of
the rim through which the apertures to receive the spokes are drilled or pierced.
That my invention may be better understood have annexed drawings thereof
which I will now proceed to describe.
Fig. 1 is a transverse section of a strip of metal having a thickened portion A in the
centre of its width.
Fig. 2 is a plan of the same.
Figs. 3 and 4 are respectively a transverse section and a longitudinal elevation of a
portion of a rim or tyre in which the strip of metal is so drawn and corrugated as to
combine the thickening A at the bottom or inside of the rim or tyre with the corruga-
tions. B at each side of the said rim or tyre.
Tubes made according to my invention are concave on their upper side and convex
having any desired number of corrugations therein on their underside as shewn in
Figs. 3 and 4 where B is the metal of their ordinary thickness and A the thickened
part drawn into the bottom or lower corrugation. The edges of the metal are brazed
together by preference at the bottom of the concave.
Having now described the nature of my said invention and the manner in which the
same is or may be performed and without limiting myself to the precise details herein-
before described as these may be modified without departing from the nature of my
said invention I declare that what I claim is
First. The improvements in metal rims or tyres of wheels for those Vehicles
mentioned in the title hereinbefore described and shewn in Figs. 3 and 4 and illustrated
in the accompanying drawings.
Second. The combination of a rim drawn with any desired number of corrugations
but having a thickened bottom or swelling on its under side as shewn in Fig. 3
substantially as hereinbefore described and illustrated in the accompanying drawings.
