I, JOSEPH HENRY HUGHES, of Park Lane, Aston juxta Birmingham in the
County of Warwick, Machinist do hereby declare the nature of this invention to
be as follows:-
This invention has reference to velocipede pedals whether rubber, rat-trap or a
combination of rubber and rat-trap, the object of which is to provide a pedal so
that the rubber blocks or equivalent or rat-trap bars can easily be detached, and to
reduce the cost of manufacturer.
According to the present method of manufacturing velocipede pedals the rubber,
felt or cork blocks are secured to the pedal by means of a pin or stretcher
fastened to the ball race plates, the rat-trap bars being also secured to the said ball
race plates.
Now my invention consists in fastening or securing the rat-trap bars in any
suitable manner (but by preference I employ pins and nuts as they are easily
detached) to the centre of the centre cover or tube in which the pedal spindle
revolves in the ordinary manner, or instead of fastening the said rat-trap bars
to the centre cover or tube I may if desired secure the rat-trap bars directly onto
the centre of the pedal spindle and provide the same with a suitable adjustable
bearing, ball races being also provided in the centre of the said pedal spindle so
that the said rat-trap bars can revolve thereon. When desired I may dispense with
the serrated edges on the rat-trap bars and insert blocks of rubber, felt, cork or
any other suitable yielding material between the said bars either at right angles
to the pedal spindle or parallel with the same, or I may use a combination of rubber,
felt, cork or other suitable yielding material and rat-trap bars.

COMPLETE SPECIFICATION.
Improvements in Velocipede Pedals.
I, JOSEPH HENRY HUGHES, of Park Lane, Aston, juxta Birmingham in the
County of Warwick, Machinist, 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 has reference to velocipede pedals whether rubber, rat-trap or a
combination of rubber and rat-trap, the object of which is to provide a pedal so
that the rubber blocks or equivalent or rat-trap bars can easily be detached, and to-
reduce the cost of manufacture.
In order that my invention may be more clearly understood 1 have illustrated
same on the annexed sheet of drawings.
Fig. 1 is part sectional plan of a rat-trap pedal constructed according to my
invention.
Fig. 2 is front elevation of Fig. 1 but not in section-and-
Fig. 3 is plan of a rubber pedal constructed according to my invention.
A is the centre cover or tube in which the pedal spindle B revolves. The rat-
trap bars C, C¹ and stretchers a, a' which are formed like a double T piece are

in any other suitable manner.
The ends of the centre tube A are provided with screwed dust caps E, E¹ for
making the pedal perfectly dust-proof.
At Fig. 3 I have shewn my invention as applied to a rubber pedal or equivalent.
In this case 1 employ two sets of stretchers F, F¹ which are fastened onto the
centre tube A by the pins G, G¹ in the same manner as the stretchers a a¹ of the
rat-trap bars C, C¹. The rubber blocks H, H' or equivalent are then secured
between the said stretchers F, F¹ by the pins and nuts I, I' in the ordinary
manner.
Instead of fastening the stretchers a a¹ or the stretchers F, F' onto the centre
tube AI may if desired fasten them directly onto the pedal spindle B and dispense
with the centre tube A. In this case suitable adjustable ball bearings would be
provided under the said stretchers a a' and E E' for the said pedal spindle B to
revolve in; and the bearings which are usually provided at each end of the
spindle B may be dispensed with if required.
When desired I may dispense with the serrated edges on the rat-trap bars C, C'
and insert blocks of rubber, felt, cork or other suitable yielding material between
the said bars C C¹ either at right angles to the centre tube A (as shewn in dotted
lines at Fig. 1) or parallel with the said centre tube A. Or I may use a
combination of rubber, felt, cork or other suitable yielding material and rat-trap
bars.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood
that I do not confine myself to the precise methods of constructing velocipede
pedals as herein illustrated and described as they may be varied without departing
from the nature of my invention but what I wish to claim is :-
Firstly. In a velocipede pedal making the rat-trap bars detachable in the
manner substantially as herein shewn and described.
Secondly. Securing the rat-trap bars or rubber blocks or equivalent to the centre
tube A in the manner substantially as herein shewn and described.
Thirdly. Connecting the rat-trap bars or rubber blocks or equivalent to the
centre tube A, whether detachable or otherwise substantially as herein
described.
