Improvements in and relating to the Attachment of Toe Clips to
Cycle Pedals and the like.
I, THOMAS BOURNE, Cycle Accessories Manufacturer, residing at 361, Rotten
Park Road, in the City of Birmingham, do hereby declare the nature of this
invention to be as follows:-
This invention relates to pedals and toe clips for cycles and other machines,
and consists in certain improvements in the pedal and toe clip's construction hav-
ing for their object. the easy affixment of the said toe clip to the pedal so as to
render it detachable at any time.
The toe clip according to this invention, which can be either made from strip
metal or wire, has its free and pedal connection ends formed with a slight enlarge-
ment or a collar upon them, such collar or enlargement having a reduced circular
neck inwards of its end of a breadth approximate to the thickness of the metal
of the pedal's side plates. These enlarged parts or collars are permanently
attached to the free ends of the toe clip or made in one piece therewith, and the
construction of the said clip is preferably that which gives to its pedal attach-
ment ends a lateral springiness always tending to distance the said ends if forced
laterally to each other.
The side plates in the rat trap pedal constructed according to this invention
have each two longitudinal and central piercings "within them, each piercing
comprising a large part, equivalent to the size of the collars on the free ends
of the toe clip, and a reduced part corresponding with the size of the necks in
the toe clip's free ends, the said large part to form a gate or entrance to the
said reduced part. The piercings or slots within the side plates, as aforesaid,
are arranged opposite each other, that is to say, the two in the one side plate
are opposite the two in the other side plate and their larger and smaller parts
are also opposite, and, preferably, the former inwards of the latter.
To fix the toe clip to the pedal the free collared ends of the former are pulled
laterally towards each other, which tensions the said free ends, so that they can
he introduced together through their respective gates in the one side plate, over
the pedal hub, and through their respective gates in the other side plate, but
only sufficiently through these last two piercings to engage the reduced necks
with the reduced parts of these piercings, when on the free ends of the toe clip
being released they separate and seat themselves with their necked ends in the
smallest portion of the slots.
When connected, the inner portions of the branches of the free ends rest within
the smallest parts of the slots in the forward side plate, and, if necessary, may

page_text: be locked in this position by a thin plate pivottedly connected to the face of the
inner side of the forward side plate, the ends of which thin plate may be slightly
concaved and sprung into position between the toe clip free members, forming,
as it were, a stay or distance piece between them. Or loose catch plates may be
hingedly connected to the inside of the forward side plate outwards of the toe
clip free ends, adapted to embrace the branches of the said toe-clip and hold them
within the reduced portions of the slots.
It is preferable that the slots in the side plates be key-hole shaped, but any
shape of slot of two sizes to constitute a gate and a stop may be used.
In adapting this invention to pedals of more than two treads the side plates
forming the same are shaped concave in cross section from their outer sides,
and have the longitudinal key-hole shaped slots in them as previously described,
the said slots in any one plate being in such a position as to be common to the
toe clip for two treads, so that the said toe clip can be adjusted and fixed to suit
any one tread.

COME DEPUTATION.
Improvements in and relating to the Attachment of Toe Clips to
Cycle Pedals and the like.
I, THOMAS BOURNE, Cycle Accessories Manufacturer, residing at 361, Rotten
Park Road, in the City of Birmingham, 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 relates to pedals and toe clips for cycles and other machines, and
consists in certain improvements in the pedals' and toe clips' constructions hav-
ing for their object the affixment of the said toe clips to the pedals so as to render
them easily detachable at any time, inter-changeable to the pedal's treads, and
also inexpensive in their production.
According to this invention a toe clip is constructed with free ends which are
to be connected to a pedal, and are fitted with collars having necks or reduced
parts or shanks inwards of the extremities of the free ends, and a pedal is formed
having side plates containing longitudinal piercings or slots of two sizes, or one
running into the other, and forming, in combination, holes similar in shape to
a key hole. The necks of the collars, as aforesaid, engage the smaller parts of the
slots and the collars themselves form adjacent abutments on both sides of the
side plate's faces.
In order that this invention may be clearly understood the same is illustrated
in the accompanying sheet of drawings, Fig. 1 being an end elevation with part
broken in section of a connected-up toe clip and pedal, Fig. 2 a top side plan of
Fig. 1 with one of the side plates broken into and shown in section, Fig. 3 a side
section of Fig. 2 upon the dotted line, Fig. 4 a like view as Fig. 3 but with the
free ends of the toe clip shown as being introduced into the slots of one of the
side plates, and Fig. 5 a view of the toe clip, Figs. 1 and 2, separated from
the pedal. In these views the toe clip a, which can be made either from strip metal
or from wire, has two free and pedal connection ends as formed as part of it,

page_text: the said ends being each fitted with a collar or enlargement a³ having a reduced
circular part neck or shank a formed upon it inwards of its extremity; the said
necks or shanks being of a breadth approximate to the thickness of the metal of
the pedal's side plate to which it is connected, and of a depth sufficient to form
its adjacent faces or sides into substantial abutments. These enlargements or
collars are permanently and rigidly attached to the free ends a² of the toe clip, or
are formed in one piece therewith, and the construction of the clip a is preferably
that which gives to the ends a² a lateral springiness always tending to distance
the said ends if they should be forced together. This springiness of the ends a² is
used to keep the parts of the toe clip which engage the side plates in their proper
positions for engagement.

The pedal shown in the drawings constructed according to this invention is a
rat trap" one, and each of its side plates ², c, is formed with a pair of longi-
tudinal piercings or slots d, d, of two sizes, the one or largest part of the said
piercings being slightly larger than the size of the collars a³ on the free ends of
the toe clip, and the other or smallest size of the said piercings being equivalent
to the size of the neck at of the said collars. The said slots or piercings 'd, d,
resemble in shape a key hole, their largest parts d² being innermost.
To connect the toe clip's free ends a² to one of the side plates c2 the said ends are
first pressed towards each other which puts them into tension, and the extremities
of the collars or enlargements a³ are first introduced through the large sized.
parts d of slots d, d, until the necks or shanks as of them come into position
opposite the sectional thickness of the side plate when by freeing the toe clip's
free ends the necks or shanks a can be introduced into the small sized parts
of the slots d, d; the said necks taking up positions at the outer extremities of
the slots they engage, and their faces or sides forming abutments against the
inner and outer faces of the pedal plate. It is found in practice that the connec-
tion of the toe clip and pedal described is sufficiently rigid for all reasonable
purposes but, if necessary, two stiffly-jointed catch plates g, g², as shown in
Fig. 6, may be used for holding the free ends of the toe clip in their distending
positions in the parts of the slots of the pedal's side plate with which they engage;
the said catches being adapted to be thrown back on their joints h to release the
said toe clip's free ends.
In Fig. 7a modified form of the toe clip is shown, the free pedal connection
ends a² in this case being formed with a number of necks or shanks a inter-spaced
by enlargements or collars a³ to constitute abutments.
This invention is applicable to all cases of pedals having side plates, or their
equivalents, of a rigid structure, such as would be the case where the pedal had
only its tread faces of rubber, the body of the side plates being of metal.
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
claim is:-
First. A toe clip whose pedal connection ends are free and formed with collars
or similar parts which have reduced necks or shanks inwards of their extremities,
in combination with a pedal whose side plates have in them longitudinal piercings
or slots of two sizes running into each other, which said slots will admit of the
collars' free introduction through their one parts, and the engagement of the
necks or shanks with the other parts, so as to attach the toe clips free ends thereto,
substantially as set forth.
Second. In combination a toe clip whose pedal connection ends are free, adapted
to spring, and formed with collars or their equivalents a³, having necks or
shanks a within them, and a pedal whose side plates have within them longi-
tudinal key hole-shaped piercings or slots d, d, of two sizes, which said slots are
adapted to receive and engage the parts a³, at, of the toe clip's free ends a², sub-
stantially as set forth in Figs. 1 to 5.
Third. In combination, a toe clip whose pedal connection ends are free, adapted

page_text: to spring and formed with collars or their equivalents a³, having necks or shanks a
within them, a pedal whose side plates have within them longitudinal key hole
shaped piercings or slots d, d, of two sizes, which said slots are adapted to receive
and engage the parts a³, as, of the toe clip's free ends a², and jointed catches g. 9,
attached to the pedal's side plate so as to engage the free ends of the pedal's toe
clip when in position in the slots, and form a holding means thereto, substantially
as described and set forth with reference to Fig. 6.
