Improvements in Pedals for Velocipedes.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-
My invention is intended to accomplish a two-fold object: first, the production
of an extremely light, graceful, and simple "rat trap" pedal; second, the
production of a simple and economical pedal which is convertible from the rat-trap
form to the rubber block form and vice-versa.
In the accompanying drawing,
Figure 1 is a plan of my improved pedal.
Figure 2 is a side view of the same.
Figure 3 is a partial sectional end view.
Figure 4 is an elevation of one of the rat-trap plates detached from the
pedal.
Figure 5 is a sectional elevation of one of the bolts and a rubber block located
thereon in lieu of the rat-trap plate.
As is well known, the rat-trap pedal is used when it is desired to make a very
firm engagement between the pedal and the foot. The so called rat-trap plates are
placed edgewise and have their edges provided with teeth or equivalent projections
adapted to penetrate more or less into the shoe.
A is the portion of the crank or arm to which the pedal is attached. B is the
shaft upon which the pedal rotates. C is the cylindrical sleeve or hub of the
pedal. D D are the end pieces of the pedal. These are applied to the ends of
the hub at right angles to the latter in the usual manner, the distance between
being a little more than the width of the foot. E, E are bolts located one at each
side of the hub, C, and parallel thereto and extended through the ends of the
end pieces D.
Above and below each bolt E each end-piece D has formed in its edge a notch d.
F, F are the rat-trap plates. The body of each of said plates is as long as the
space between the end pieces, DD and each end of each of said plates F is
provided with a small projection d', extending into the notches d. At points along
the longitudinal axis of said plate, the latter has cut into it transverse slots f, and
the alternating portions of metal f', between said slots and between the outermost
of said slots and the ends of the plates F, are bent to opposite sides of the
longitudinal axis of the plate sufficiently to extend around opposite sides of the
bolt E to which the plate is applied.
The lateral bending of the metal along said longitudinal axis thus serves a
two-fold purpose, namely, to secure the plate to the bolt E, and to bring the edges
of the plate directly into the plane of the bolt. The engagement of the
projections d' in the notch d, prevents the rotation of the plates F, upon the
bolts E. Said plates F, are provided with teeth.
It will be observed that the plates F are of such form as to permit them to be
made out of sheet metal by a single stroke of a die, and that the notch d, may be
formed in the end-piece D, at the same time that the latter is stamped from sheet
metal in a die, and that no further fitting or rivetting is required in applying said
plate F to the pedal.

page_text: It will also be observed that the plates F, may be readily removed by the
removal of the bolts E. When said plates have been so removed, the ordinary
rubber pedal blocks F (Figure 5) may be applied to said bolts in lieu of said
plates F. Thus it is easy to supply the market with either a desirable form of
rat-trap or rubber pedal or customers may be furnished with a pair of rat-trap
plates and rubber blocks G, and then said customers may use the pedal as a rat-trap
pedal or as a rubber pedal."
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents, I declare that what I claim is :-
:-
1. A pedal having a hub C, end pieces D, D, bolts, E, E, plates, F. F. having
toothed edges and slotted transversely along the longitudinal axis and having the
metal between the slots so formed and between the outermost of said slots and the
ends of said plates extending alternately to opposite sides of said bolts, and said
plates F being suitably secured against rotating with reference to the medal,
substantially as described.
2. In a pedal, the combination of the hub C, end-pieces D D provided with
notches d, bolts E E, extending through said end-pieces parallel to said hub and at
opposite sides to the latter plates F having toothed edges and projections d',
extending from said notch d, and slotted transversely along longitudinal axis, and
the metal between the slots so formed and between the outermost of the said slots
to the ends of said plates F, extending alternately to opposite sides of said bolts,
substantially as described.
