Cambridge Cycle Manufacturers do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to provide the means of forceing wired tires quickly
on to the rims of wheels. The machine consists of a bed-plate or frame, and a clamp
(one side of which forms the segment of a circle) with a lever attached. The wheel
to he shod is secured to the bed-plate or frame. The wired tyre having first been put
by hand into the groove of the rim as far round as it will go. The segmental clamp
is then put over the remaining portion of the tyre and operated by the lever until the
edge of the segment coincides with the edge of the rim. The tyre is then pushed off
the segment into the groove of the rim and the wheel is shod.

COMPLETE SPECIFICATION.
An Improved Machine for Putting Wired Tyres on Velocipede and
other Wheels having Grooved Rims.
We, CHARLES JOHN HOWES, and GEORGE NEVILLE HOWES, of 13 Regent Street,
Cambridge, Cycle Manufacturers, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
The object of this invention is to provide the means of forcing wired tyres quickly
on to the rims of wheels.
The machine consists of a bed-plate or frame and a clamp, (one side of which forms
the segment of a circle), with a lever attached.
The wheel to be shod is secured to the bed-plate or frame. The wired tyre having
first been put by hand into the groove of the rim as far round as it will go. The
segmental clamp is then put over the remaining portion of the tyre and operated by
the lever until the edge of the segment coincides with the edge of the rim, the tyre
is then pushed off the segment into the groove of the rim, and the wheel is shod.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of a machine constructed according to our invention, Figure 2
is a vertical section and Figure 3 an end elevation of the same.
a is the bed-plate, b is the segmental clamp, c the lever by which it is actuated the
two being connected together by the rod c¹ whose end is provided with a double hook
to receive the segmental clamp b, d is the wheel and e is the tyre to be put onto it, the
latter is only shewn in Figure 1. ff are uprights provided at the base with pegs to
drop into the holes g g in the bed-plate, these uprights hold the wheel whilst the tyre
is being put on. For small wheels a single upright placed centrally on the bed-plate
is sufficient. The edge of the clamp 6 is grooved in the middle as shewn at Figure 4
and towards its end the lower side of the groove is cut away as shewn at Figure 5, the
object of this is to allow of the tyre being readily transferred from the clamp to the
wheel.
The machine is provided with several segmental clamps of different curvatures to

page_text: suit wheels of different radii. It. is to be observed that although it is better that the
clamp should have the same curvature as tho wheel a small variation is permissible.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. The segmental clamp in combination with apparatus for, actuating the same and
for holding the wheel.
2. Our improved machine substantially as described and shewn in the drawings.
