Improvements in Cranks and Pedals, and Mode of Attachment
to Cycles.
1, GEORGE JAMES DOEL of 27, Easton Street High Wycombe, in the County
of Buckingham, Cycle Dealer, and JOSEPH WATKIN MONEY of 44 Denmark
Street High Wycombe in the County of Buckingham, Cycle Maker, 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:--
The ordinary method of fixing cranks are open to serious objections, the old
fashioned method of fixing cranks have been superceded by what is known as the
cotter pin and nut, the latter method is open to the objections of catching the
riders trousers and causing serious inconvenience and annoyance.
We propose
doing away with the cotter, and similar methods of fixing cranks. The method we
propose to adopt is shown in the accompanying drawings.
Fig. 1 Sheet 1. shows front view with transverse bar A. made in the solid crank
to about half the thickness of boss shown in Fig. 2 Sheet 1. Fig. 3 Sheet 1 shows
end of spindle slotted out to proper depth D. to receive transverse bar A. Fig. 4
Sheet 1. is boss of crank showing method of attachment to driving spindle. Fig. 2
Sheet 1. shows crank attached to driving spindle. The screw Fig. 5 Sheet 1. passes
through transverse bar A. passing into screw hole D', and brings slot D. Fig. 3
Sheet 1. into transverse bar A. thus holding the whole perfectly rigid.
The present crude method of fixing pedals has been an acknowleged failure in
cycle construction. Several methods have been adopted as improvements on the
old method. The pedal nut at the back of crank renders it a necessity to have the
tread of a cycle wider of at least one inch than is necessary with our combination
crank and pedal pin as shown in the accompanying drawings.
Fig. 1 Sheet 2. shows crank and pedal pin properly connected. Fig. 2 and 3.
Sheet 2 are sections of pedal pin on the end of crank Fig. 2 Sheet 1 at B instead
of slot as usual method. We propose a shoulder and tennon C. with screw and
nut E the pedal pin. Fig. 3 Sheet 2. is also forined with shoulder and when
brought into position on crank at B. Fig. 2 Sheet 1. the nut E. being brought into
position brings the faces B. and B2 Fig. 1 Sheet 2 together thus making the pedal
imovable, and so by this combination of crank and pedal the back of crank is
parallel thus contracting the width of tread in the cycle by at least one inch.
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
clain is
1. A method of attaching cycle cranks to driving spindle by means of a slot in
spindle end so as to receive transverse bar in boss of crank being held in position
by means of a screw brought up to face of crank substantially as described in
illustrated in Fig. 1, 3, and 4 on Sheet 1 in the drawings.
2. A method of attaching pedals to cycle cranks by means of a shoulder and
screw tenon substantially as described and illustrated in Fig. 1. Sheet 1. in the
drawing.

page_text: 3. A method of attaching pedals to cycle cranks by means of an eye in pedal pin
and a shoulder on pedal pin to be held in position by a nut on screwed crank head
substantially as described and illustrated in Fig. 1, 2, & 3 in Sheet two in the
drawings.
