PROVISIONAL SPECIFICATION.
Improvements in connection with Velocipedes.
We, WILLIAM BOWN LIMITED, 308 Summer Lane, Birmingham in the County
of Warwick, Engineers and General Manufacturers and GEORGE EDWARD
ASTON, 203 Clifton Road, Aston juxta Birmingham aforesaid, Machinist, do
bereby declare the nature of this invention to be as follows:-
This invention has reference to an improved method for securing or fixing the
pedals onto the driving cranks of a velocipede, the object of which is to firmly
secure the pedal spindle into the said driving crank without the end of the said
pedal spindle protruding beyond the inner face of the said crank.
"
According to our invention we provide the usual tapped hole at the end of a
driving crank into which the ond of a pedal spindle is screwed so as to remain flush
with the inner 'face of the said crank, also formed at the end of the said driving
crank and at right angles to the tapped hole into which the said pedal spindle is
screwed is another hole placed in such a position that when a cotter pin is inserted
therein it abutts a certain distance into the tapped hole into which the pedal spindle
is screwed, but in order to enable the said pedal spindle to be screwed into the said
crank that portion of the said cotter pin which protrudes into the said tapped hole
in the crank is cut away to correspond with the circumference of the said tapped
hole and a screw thread formed thereon of the same pitch as the thread on the end
of the said pedal spindle, by which means it will be easily understood that when
the pedal spindle has been screwed into the said crank and the said cotter pin forced
"home," the screw threads on the cut away portion of the said cotter pin will bind
upon the screw threads on the end of the said pedal spindle by which means
the said pedal is firmly and securely fixed to the said driving crank.
Dated this 13th day of November 1895.
We WILLIAM BOWN LIMITED, 308 Summer Lane, Birmingham, in the County
of Warwick, Engineers and General Manufacturers and GEORGE. EDWARD
ASTON 203 Clifton Road Aston juxta Birmingham aforesaid Machinist do
hereby declare the nature of onr said invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:
Our invention has reference to an improved method for securing or fixing the

page_text: According to our invention we provide the usual tapped hole at the end of a
driving crank into which the end of a pedal spindle is screwed so as to remain flush
with the inner face of the said crank; also formed at the end of the said driving
crank and at right angles to the tapped hole into which the said pedal spindle is
screwed is another holo place in such a position that when a cotter pin is inserted
therein it abutts a certain distance into the tapped hole but.in order to enable the
said pedal spindle to be screwed into the said crank that portion of the said cotter
pin which protrudes into the said tapped hole in the crank is cut away to correspond
with the circumference of the said tapped hole and a screw thread is formed thereon
of the same pitch as the thread on the ends of the said pedal spindle by which means
it will be easily understood that when the pedal spindle has been sorewed into the
said crank and the said cotter..pin forced "home," the screw threads in the cut
away portion of the said cotter pin will bind uponithe screw threads on the end of
the said pedal spindle by which means the said pedal is firmly and securely fixed
to the said driving crank.
In order that our invention may be clearly understood we have appended
hereunto a full sized sheet of drawings upon which we have illustrated the method
of carrying our invention into practical effect.
Figure 1. is a plan view of a velocipede driving crank A with the end in which
the pedal spindle is secured shewn in section.
Figure 2 is an edge view of Figure 1. shewing the end in which the pedal spindle
is secured in section also.
Figure 3. is a similar view to Figure 2. shewing.a portion of the pedal spindle B
secured in position.
Figures 4.& 5 are edge & front views respectively of the cotter pin and nut.
In carrying our invention into practice we provide the usual tapped hole a! at the
end' of the driving crank A into which the end of the pedal spindle B is secured so
as to remain flush with the inner face or surface. We also form at the same end
of the driving crank and at right angles to the tapped hole a' another hole a³ placed
in such a position that when the cotter pin as is inserted therein it abutts a certain
distance into the tapped hole but in order to enable the said cotter pin to be
inserted after the pedal spindle has been screwed in the portion which protrudes
into the tapped hole is cut away to correspond with the circumference of the said
tapped hole and a screw thread a' cut thereon of the same pitch. as the thread on the
end of the pedal spindle as shown at Figure 5 by which means it will be easily
understood that when the pedal spindle has been screwed into the crank & the
cotter pin inserted by tightening up the nut a which screws onto the end of the
cotter pin as the said cotter pin will bind the screw threads on the cut away portion
on to the screwed end of the pedal spindle thus firmly & rigidly securing and
locking the pedal spindle into the crank.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. The means and method substantially as herein shewn and described
for securing and locking pedal spindles into the driving cranks of velocipedes.
Second. In securing pedal spindles to velocipede cranks the use of a cross
locking pin having a hollowed' and threaded', portion as for tightening against the
screwed neck of the pedal pin by means of a nut a substantially as set forth and
'shown.
