A New or Improved Lifter for Removing Pneumatic Tyres from
Cycle Wheel Rims.

Lancaster, Comb Manufacturer, do hereby declare the nature of my said 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 lifter for removing pneumatic tyres
from cycle wheel rims and consits of a specially shaped handle or lever tapering
from one end to the other, the outer end being curved or bent to allow of the
same being pressed or placed under a pneumatic tyre for the purpose specified.
The lifter may be composed of either horn, bone, vulcanite with or without

In all the figures the same letters are employed to indicate corresponding
parts.
A. is the specially shaped handle or lever tapering from the bottom end B to the
other end or point C; the latter being curved or bent as shown in the drawings
to allow of the same being pressed or placed under a pneumatic tyre for the
purpose of lifting or removing the latter from the rim of the cycle wheel. The
lever A is composed of either horn, bone, vulcanite, or other analogous materials,
such as, strong wood, papier-mache, woodite, metal and the like. When made of
wood, papier-mache, woodite, metal and the like the aforesaid handle or lever A
may be strengthened by means of the rib I as shown in Figs. 6, 7 and 8; and
when made of vulcanite or other analogous materials of a mouldable nature may
be strengthened by the insertion of the wires K of any suitable width and
thickness.
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:-
The new or improved lifter for removing pneumatic tyres from cycle wheel
rims, the said lifter being composed of either horn, bone, vulcanite with or
without strengthening ribs or wires, or other analogous materials, such as, strong
wood, papier-mache, woodite, metal, and the like, substantially as described and
as illustrated in the drawings.
