Improvements in Cycle Frames.

page_text: Improvements in Cycle Frames.
1, MIKAEL PEDERSEN, of The Dursley Pedersen Cycle Co., Dursley, in the
County of Gloucester, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to cycle frames of the kind described in the Specification
of former Letters Patent granted to me No. 18371 of 1893, the chief object of my
invention being to adapt such frames for use by ladies.
According to my present invention the bars or stay which heretofore extended
from the ends of the fork of the rear wheel to the top of the fork of the front
wheel and which I hereinafter refer to as the longitudinal stay are arranged
lower down, that is to say, the front end instead of being connected to the front
wheel fork at the upper end of the same is connected to it at the point just above
the front wheel also the seat instead of being suspended between the bars which
extend upwardly and rearwardly from the bottom bracket and the top of the
front wheel fork is suspended between two sets of upwardly projecting bars
namely, the upwardly and rearwardly projecting bar hereinbefore mentioned
and another upwardly projecting bar or stay extending forwards from the endis
of the rear wheel fork, and crossing the aforesaid upwardly and rearwardly pro-
jecting bar wires being arranged between the upper end of the said forwardly
projecting stay and a point where the rearwardly projecting stay crosses the
longitudinal stay or any other suitable point.
With this construction a gap is formed between the front of the seat and the
head of the machine.
Another improvement consists in forming the upper end of the front wheel
fork with a tube or cylinder into which the stem of an ordinary handle bar can
be inserted and fixed. The bar which extends from the bottom bracket to the
upper end of the fork may be connected to a lug on the said fork by a pin, or it
may be provided with a socket or ring which fits over the said upper end of
the fork and works between collars thereon, balls being arranged between the
said ring and collar to form a ball bearing.

ascertained in and by the following statement:-
My invention relates to cycle frames of the kind described in the Specification
of former Letters Patent granted to me No. 18371 of 1893, the chief object of my
invention being to adapt such frames for use by ladies.
According to my present invention the bars or stay which heretofore extended
from the ends of the fork of the rear wheel to the top of the fork of the front
wheel and which I hereinafter refer to as the longitudinal stay are arranged
lower down, that is to say, the front end instead of being connected to the front
wheel fork at the upper end of the same is connected to it at the point just above
the front wheel; also the seat instead of being suspended between the bars which
extend upwardly and rearwardly from the bottom bracket and the top of the
front wheel fork is suspended between two sets of upwardly projecting bars
namely, the upwardly and rearwardly projecting bar herein before mentioned
and another upwardly projecting bar or stay extending forwards from the ends
of the rear wheel fork, and crossing the aforesaid upwardly and rearwardly pro-
jecting bar wires being arranged between the upper end of the said forwardly
projecting stay and a point where the rearwardly projecting stay crosses the
longitudinal stay or any other suitable point.
With this construction a gap is formed between the front of the seat and the
head of the machine.
Another improvement consists in forming the upper end of the front wheel
fork with a tube or cylinder into which the stem of an ordinary handle bar can
be inserted and fixed. The bar which extends from the bottom bracket to the
upper end of the fork may be connected to a lug on the said fork by a pin, or it
may be provided with a socket or ring which fits over the said upper end of
the fork and works between collars thereon, balls being arranged between the
said ring and collar to form a ball bearing.
In the accompanying drawing,
Figure 1 is a perspective view of a ladies' bicycle constructed according to
the invention.
Figure 2 is a sectional side elevation of the upper end of the front wheel fork
shewing the method of attaching the frame and the handle bar; and
Figure 3 is a similar view of the modified construction thereof.
a is the front or steering wheel of the machine, b the rear or driving wheel,
c, c the pedals, d the chain wheel mounted upon the pedal axle, e the chain
and the chain wheel mounted upon the hub of the rear driving wheel b.
h, h are the front tubes, i, i the bottom tubes, j, j the tubes extending up-
wards from the bottom bracket to support the saddle or seat k, is the front
fork and m, m are the stays extending from the bottom bracket and connected at
the upper end to the upper end of the front fork; all these parts are of ordinary
construction.
n, are the longitudinal bars or stays which heretofore extended from the
ends of the fork of the rear wheel to the top of the fork of the front wheel but
which according to my present invention extend from the said rear wheel fork to
a point n' upon the said fork 7, that is to say, at the point where it is connected
to the stays h just above the front wheel a.
o, o are the bars or stays which project from the ends of the rear wheel fork
and cross the upwardly extending bars j, j so as to support the other end of the
saddle which is thus suspended between the upper ends of the stays j, j and
the said stays o, o. P, Pare the wires which connect the upper end of the
stays, to the end of the rear wheel fork as heretofore and q, q are the extra
wires which connect the upper ends of the stays o, o to the points where the
stays n, n and j, j cross one another.
With this arrangement, as will be clear, a gap is formed between the front
of the seat k and the head of the machine.
Figure 2 illustrates the improvements which I apply to the upper end of the

page_text: front wheel fork / to enable the said fork to receive the stem of an ordinary handle
bar. To this end the upper ends of the tubes forming the front wheel fork are
formed or fitted into a tubular or cylindrical portion or socket into which the
handle bar stem s can be fitted and clamped in the usual manner.
The bars or
stays m which extend from the bottom bracket to the upper end of the fork
are united and provided with a slot m adapted to fit over a lug 1 formed upon
the cylindrical portion of the fork and being pivotally connected thereto by
means of the pin t as clearly shewn.
Figure 3 shews the modified arrangement for connecting the cylindrical portion
or socket r of the fork to the stays m, m. In this case the upper end of the
stays m, m is provided with a ring which fits over the cylindrical portion of the
fork and works between collars v, provided upon the said fork end, balls w, w
being arranged between the lower ring and the said collar u to form a ball
bearing to diminish friction.
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 a cycle of the kind referred to, the described construction of frame adapted
for the use of ladies, substantially as hereinbefore described and illustrated in
Figure 1 of the accompanying drawings.
2. In cycle frames of the kind referred to, providing the upper end of the
front fork with a cylindrical or tubular socket into which the stem of an ordinary
handle bar can be fitted, the said socket being pivotally connected to the frame,
substantially as herein before described and illustrated in Figures 2 and 3 of the
accompanying drawings.
3. Cycles constructed substantially as herein before described and illustrated
in the accompanying drawings.
