PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of the Rims of Wheels of
Velocipedes and other Vehicles.
1, MIKAEL PEDERSEN, of Kingsley House, Dursley, in the County of
Gloucester, Engineer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in the manufacture of wooden wheel rims
chiefly of velocipedes, and also applicable to other wheels.
According to my invention the length of wood of the required section from
which the rim is to be made is bevelled or scarfed from each end for any required
distance as usual but I form the two bevelled surfaces which come together with
longitudinal grooves or mortices, the grooves on one surface corresponding with the
parts or tongues between the grooves on the other surface, so that, when the two
surfaces are brought together and pressure is applied, the tongues on one surface
are forced into the grooves on the other surface, whereby a very secure joint is
formed, glue being employed if necessary.
In practice the width of the tongues is advantageously slightly greater than that
of the grooves. The tongues and grooves may if required be made with inclined or
receding sides so as to dovetail one within the other in which case the parts are
slid one into the other instead of being pressed together.
Dated the 14th day of December 1894.

MIKAEL PEDERSEN of Kingsley House, Dursley, in the County of Gloucester,
Engineer 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 improvements in the manufacture of wooden wheel
rims chiefly of velocipedes, and also applicable to other wheels. According to my
invention the length of wood of the required section from which the rim is to be
made is bevelled or scarfed from each end for any required distance as usual but
I form the two bevelled surfaces which come together with longitudinal grooves or
mortices (A. Fig. 1) the grooves on one surface corresponding with the parts or
tongues between the grooves on the other surface so that, when the two surfaces
are brought together and pressure is applied, the tongues on one surface are forced
into the grooves on the other surface, whereby a very secure joint is formed, glue
being employed if necessary.
In practise the width of the tougues is advantageously slightly greater than that
of the grooves.

page_text: I sometimes make the tongues and grooves with inclined or receding sides so as
to dovetail one within the other in which case the parts are slid one into the other
instead of being pressed together.
Having now particularly described and ascertained the nature of said
my
invention, and in what manner the same is to be performed, I declare that what
I claim is
The combination of longitudinal grooves and tongues with a bevelled or scarfe
joint for making wooden rims, substantially as set forth in the Specification and
particularly shown in the drawings on Sheet 1.
Dated this 13th day of September 1895.
