PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
I, GEORGE TOWNSEND, of Hunt End, near Redditch in the County of Worcester-
shire, Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the pedals of Velocipedes and it has for its objects,
rendering the bearings of the pedals perfectly dust proof, and generally simplifying
the construction and arrangement of the several parts whereby a more perfect pedal
is obtained.
I construct my improved pedal in the following manner :-I form the central sleove
for the pedal pin out of a length of steel tube, and I block or roll out the ends to form
the recesses for the ball-bearings, and to receive the side plates which may be made
of malleable castings or wrought iron stampings. The pin is made out of a length
of steel bar. The one end is turned down to form a shoulder to complete the race
or channel-with the recess in one end of the sleeve of one of the ball bearings of
the pedal, and the other end is threaded to receive an internally screwed cone which
-with the recess in the other end of the sleeve-forms the race or channel of the
other ball bearing, suitable balls being interposed between the respective parts. In
the face of this cone is cut a recess within which an extention of the central sleeve
fits to make the bearing dustproof, a packing of india-rubber or other suitable pliant
material being placed within the said recess. On to the outer end of the pedal
pin is screwed a flanged cap adapted to fit over an extention of the central
sleeve to make the bearing dustproof, the inner face of the said cap being fitted
with a washer of any suitable pliant material. Instead of screwing this cap to the
pedal pin it may be screwed or otherwise fixed to-or even form part of-the
outer side plate and thus enclose the outer ball-bearing. On to the cone threaded on
the pedal pin is formed an extension on which are cut two flats, to adapt the said
extension to fit within the slot in the crank, a suitable nut being screwed on to the
end of the pin to lock the cone and pedal at one operation to the crank. As a
modification I sometimes form the recesses for the ball-bearings in the side plates, or in
independent pieces adapted to be fitted to a straight central sleeve and to suitably
shaped side plates, which made out of steel plate stampings. As a further modifica-
tion the side plates may be blocked to a suitable shape to form the dust proof covers,
the ends of the central sleeve being adapted to screw to the said plates.

1, GEORGE TOWNSEND, of Hunt End, near Redditch, in the County of Worcester-
shire, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and claimed in and
by the following statement :-
My invention relates to the pedals of Velocipedes and it has for its objects, rendering
the bearings of the pedals perfectly dust-proof, and generally simplifying the con-
struction and arrangement of the several parts whereby a more perfect pedal is

page_text: I construct my improved pedal in the manner illustrated by the accompanying
drawing, in which Figures 1. 2. and 3. are views in longitudinal section of various
manners in which my invention may be carried into practical effect.
Throughout the several views similar parts are marked with like letters of
reference.
Referring to Figure 1. of the accompanying drawing. I form the central sleeve A
for the pedal pin B out of a length of steel tube and I block or roll out the ends to
form the recosses a a for the ball bearings and to receive the side plates C
which may be made of malleable castings or wrought iron stampings. The pin B
is preferably inade out of bar steel with one end jumped, or set, up to allow of the
formation of the shoulder 6 to complete-with one of the recesses a in one end of
the sleeve A-the race or channel for the balls x. x. etc. forming one of the ball
bearings of the pedal, and the other end is threaded to receive an internally screwed
cone D which-with the recess a in the other end of the sleeve A-forms the race
or channel for the balls & c. etc., forming the other ball bearing. In the face of the
cone D is cut a recess d within which an extension a¹ of the central sleeve A fits to
make the bearing dust-proof, a packing or washer E of india-rubber or other suit-
able pliant material being placed within the said recess.
On to the outer end of
the pedal pin B is fixed by the screw a flanged cap adapted to fit over an
oxtension a² of the central sleeve A to make the bearing dust-proof, the inner face
of the said cap being fitted with a washer E¹ of any suitable pliant material. On to
the cone D threaded on the pedal pin B is formed an extension d' on which are cut
two flats to adapt the said extension to fit within the slot in the crank, a nut D being
screwed on to the end of the pin to lock the cone and pedal-at one operation-
to the crank. Instead of screwing the cap F to the pedal pin it may either form
part of the outer side plate C as illustrated by Figure 2. of the accompanying
drawing, or it may be screwed or otherwise fixed to the extension a² of the sleeve &
as illustrated by Figure 3 of the accompanying drawing.
As a further modification I sometimes form the recesses a a for the ball bearings
in the side plates C, or in independent pieces A' adapted to be fitted to a straight
central sleeve and to suitably shaped side plates as illustrated by Figure 3. of the
accompanying drawing.
In the outer end of the pedal pin B is formed a slot or its equivalent whereby it
can be turned by a screw-driver or its equivalent to adjust the bearings without
removing the pedal from the crank by merely slackening the lock nut D¹ and
retightening it after the adjustment is completed.
It will be seen that by this construction of the pedal, the outer bearing thereof can
be entirely enclosed, still retaining the lateral adjustment of the bearings. I am
aware that pedals have already been constructed with the outer bearing enclosed, but
such pedals have had no lateral adjustment.
I wish it to be particularly understood that I do not limit myself to the exact
details of construction herein before set forth, but hold myself at liberty to make such
changes and alterations as fairly fall within the spirit and scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I 4
claim is ;-
1st. The improvements in pedals for velocipedes substantially as herein described
and shown.
2nd. In a pedal for Velocipedes, making the fixed cone on the pedal pin on the
outer end thereof, and the adjustable cone on the inner end, as and for the purpose 5
set forth.
3rd. In a pedal for Velocipedes, locking the adjustable cone on the pedal pin, and
fixing the pedal to the crank by one nut, as set forth.
4th. In a pedal for Velocipedes, forming the side plates independent of the part or
parts forming the recesses for the ball bearing as set forth.

page_text: 5th. In a Velocipede, the combination of the pedal pin B having a fixed cone or
shoulder b at its outer end, and an adjustable cone D having an annular recess d and
lock nut D on its inner end, the sleeve A having recesses a a with extensions a²
formed in or fixed thereto, the side plates C. C. the washers E and F, the cap F, and
the balls x etc., all combined, arranged, and operating as and for the purpose set
forth.
