We, FRED PRIESTLEY of Woll Head, Greetland, neat Halifax. Publican, and
ABRAHAM JONES of Grattan Street, Burley Road, Leeds, Mechanical Engineer,
both in the County of York, do hereby declare the nature of this invention to
be as follows
-
The object of our invention is to construct pedals for velocipedles in such a
manner that they may be readily converted from racing pedals to ordinary pedals,
and vice versa.
According to our invention we form the pedal fame of sheet metal, so as to have
a bearing surface on the edge of the metal at both sides of said pedal
The edges
of the metal are bent in, so as to form a clip, and plates are provided having
similar clip edges, the said plates being provide with bolts or other fastenings for
attaching them to the pedal fiame on each side of the spindle. Strips or other
pieces of india rubber or similar elastic material are placed between the plates and
the pedal fame, which latter are clamped together by the fastenings before referred
to in such a manner as to leave two strips of portions of elastic material projecting
on either side of the pedal frame.
When it is equined to employ the pedal for racing purposes, the plates and
elastic material are unclamped from the pedal frame, when the edges of the metal
act as a beating sui face for the foot of the idea; and when the pedal is required
for ordinary pui poses the elastic material can readily be fixed in position by means
of the plates and clamps.
The pedal fiame may be of the ordinary square type, but we prefer to bend it so
as to come to a point at the back and front, the surface being cui ved to fit the
bend of the foot. In this manner the side strain on the muscles of the foot and
leg is greatly relieved, the foot being enabled to rest in a natural position.

We, FRED PRIESTLEY, of Well Head, Greetland, near Lalifax, Publican, and
ABRAHAM JONES, of Grattan Street Builey Road, Leeds, Mechanical Engineer,
both in the County of York. do hereby declare the nature of this invention and
in what manner the saine is to be performed to be particularly described and
ascertained in and by the following statement:-
The object of our invention is to construct pedals for velocipedes in such a
manner that they may be readily converted from racing pedals to ordinary pedals,
and ce versa.
In order that our invention may be clearly understood, we will proceed to describo
same with reference to the accompanying diawings, in which similar letters rofer
to like parts in all the figures.

Figures 1, 2, and 3, are respectively, plan, cross section, and fiout elevation, of
a racing or rat-trap" pedal of the ordinary square type; and Figures 4, 5, and 6,
are similar views of the same pedal, shewing our invention applied thereto
Figure 7 is a plan of a racing pedal of a modified form; and Figures 8, 9, and 10,
are respectively a plan cross section, and fout elevation of the same pedal, with
another portion of our invention applied thereto. Figure 11 is a detail view
According to our invention we construct the pedal in the ordinary form, having
a sheet metal frame A with a bearing surface on both sides of the pedal B, B, are
pieces of india rubber which are provided with metal plates C, C, and suitable holo3
allow of the plates C, C, and rubber B, B, being firmly bolted to the frame A, A,
by means of bolts D. The india rubber is thus held firmly between the plates C, C,
and the frame A, A, leaving a portion of the rubbor B, B', projecting up above
the edge of the pedal fiame, as best seen at Figure 5.
When it is required to employ the pedal for racing purposes, the plates C, C,
and india rubber pieces B, B, are unbolted from the pedal frame, when the edges
of the frame A, A, act as a bearing surface for the foot of the der; and when
the pedal is requned for ordinary purposes the elastic material can be readily fixed
in position by means of the plates C, C, and bolta D.
In the fuzz six figures ne bave shown, ont loveation applied to an ordmary pedal,
having straight sides, but we have found straight sided pedals are liable to stiain
the muscles of the foot and leg, owing to the side pressure ou the foot whilst
riding, so in order to obviate this disadvantage we have constructed the pedal in a
bent form, so as to bring the beating of the foot in the centre of the sole, and this
form of pedal can be seen on reference to Sheet 2 of the accompanying diawings.
The plate A is preferably formed in one piece, being bent so as to form projecting
portions E and F in the centre of the pedal at the back and front. The plate A
is cut so as to form a suitable curve to suit the shape of the foot (as seen at
Figure 11).
When it is required to convert this pedal into one with an india rubber tread,
we bolt the rubbers B, B, and plates C, C, into position, and a pedal is thus
obtained as seen at Figures 8, 9, and 10.
It will be readily seen that the strain on the muscles of the foot and leg, is
greatly reloved when employing the pedal above descubed, as the foot is enabled
to be inclined or twisted and is not held in an unnatural position, the strain being
taken by the centre of the sole.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In pedals for velocipedes and the like, the elastic pieces B, B, and plates C, C,
substantially as and for the purposes set forth.
2. The combination of the frame A, A, the elastic pieces B, B, the plates C, C,
and bolts D, D, substantially as and for the purposes set forth.
3. The pedal having a frame A, pointed at the back and front and shaped to
the curve of the foot, substantially as and for the purposes set forth,
4. The general arrangement, construction and combination of the various paits
forming our invention for improvements in pedals for velocipedes, substantially as
and for the purposes set forth.
