Improvements in Cycle Pedals.
We, WILLIAM ARTHUR LLOYD, Managing Director of W. A. Lloyd's Fittings,
Limited, of Park Street, in the City of Birmingham, and HENRY KEELING, of
254, Park Road, Hockley, Birmingham, aforesaid, Machinist, do hereby declare
the nature of this invention to be as follows:
This invention relates to width-adjusting pedals for cycles, and has for its
object to simplify the construction and arrangement of the parts of such pedals,
and to render the same more easily adjustable.
The improved adjusting pedal consists of a primary fixed frame and a secondary
movable or adjustable one, with the former having end plates carrying the bearing
cups, in the stepped or shoulder inner ends of which, the open ends of an
axially directed and outside screwed waist, barrel or equivalent, with a milled
or nut-facetted collar thereon and wherethrough the spindle of the pedal passes,
takes and is capable of being rotated when turned by the milled or facetted
collar.
Enclosing the screwed portion of this rotatable barrel is a casing or sleeve
covering, which takes upon the shoulder or stepped inner ends of the ball cups,
and has longitudinal slots formed along its two opposite sides, wherethrough the
shanks of a pair of rack-edge plates carried on the sides of the supplementary
movable frame, inwardly pass and their teeth engage with the screw threads of
the barrel, which, when rotated, slides the rack teeth longitudinally within their
guide slots and gives the movable frame a traversing adjusting movement.
The supplementary frame is preferably of the figure of a letter U, with the
upper and lower edges of the returned ends provided with stops or horns; so
also are the ends of the side plates of the fixed frame, the pedal being reversible,
with both edges formed alike.
The inner ends of the sides of the movable frame have guide studs, blocks or
equivalents on their outside faces, which pass through and are guided by longi-
tudinal slots formed along the opposite side plates of the fixed frame, whilst the
opposite sides of the movable pedal also have adjustable slots or clearances to
admit of the longitudinal traverse of the same over the outer end plate of the
fixed part.
The invention is applicable either to rubber pedals, rat-trap pedals and com-
bination rubber and rat-trap pedals.

We, WILLIAM ARTHUR LLOYD, Managing Director of W. A. Lloyd's Fittings,
Limited, of Park Street; in the City of Birmingham, and HENRY KEELING, of
254, Park. Road, Hockley, Birmingham, aforesaid, 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:-
ܝ ݂ܕܢ
This invention relates to width adjusting pedals for cycles and has for its
object to simplify the construction and arrangement, of the parts of such pedals,
and to render the same more easily adjustable.
.
Figure 1 ofthe accompanying drawing represents a top side plan of an
extending or width adjusting cycle pedal constructed according to our invention.
Figure 2 is a side elevation and Figure 3.an end view of the same.

Figure 4 is a longitudinal section of the said pedal; upon the dotted lines. x
Figure 2.
Figure 5 is a topside plan, but with a portion broken away, of the fixed,part
of the pedal, which is complete in itself, and has fixed side plates and end plates
and spindle bearings, the same as an ordinary pedal.
Figure 6 is a cross section of Figure 4, upon the dotted line.
Figure 7 represents the spindle of the pedal, with its fixed and adjustable
bearing cones, separately."
Figure 8 is a plan of the body of the pedal, separately and Figure 9 is a section
of Figure 8 upon the dotted line 3.
Figure 10 is a plan of the movable part, which is adjustable upon the fixed
frame of the pedal for altering the width, and Figure 11 is a section upon the
dotted line .
Figure 12 is a plan of the screw-threaded waist of the pedal and Figure 13 ans
end elevation of the same.
The improved adjusting pedal consists of a primary fixed frame a and a
secondary movable or adjustable one b, the former being complete in itself and
having side plates a¹, and end plates a², carrying the bearing cups a³, in the
stepped or shouldered inner or mouth ends a, of which the open ends c¹, of an
axially directed and outside screwed rotatable waist or barrel c, having a milled
or nut-facetted collar, thereon and wherethrough the spindle d, of the pedal.
passes, takes and is capable of being 1otated when turned by the milled or
facetted collar.
Enclosing the screwed portion of this rotatable barrel, which is thus, mounted, :
on fixed end bearings carried by the primary frame, is a casing or sleeve.
covering e, one end e, of which takes over the shouldered or stepped part,as, of
the ball cup a³, whilst the other end e³, rests upon a collar ³, of the waist.
Longitudinal guide slots e³ are formed along its two opposite sides, wherethrough
the shanks f¹, of a pair of rack-edge plates f³, carried on the sides f³:of, the
supplementary movably frame b, inwardly pass and their teeth or rack edges f*,
engage with the screw threads of the barrel, which, when rotated, slides the said
plates, longitudinally within their guide slots 3; and gives the movable. frame
a traversing adjusting or extending movement.
The supplementary frame b, is preferably of the figure of a letter U, with 4
the upper and lower edges of the returned end f³, provided with stops or horns f,
so also are the ends.b, of the side plates of the fixed frame, the pedal being
reversible, with both edges formed alike.
The inner ends of the sides of the movable frame have guide studs f, or blocks
or equivalents on their outside faces, which pass through and are guided by 5

page_text: longitudinal slots a", formed along the opposite side plates of the fixed frame,
whilst the opposite sides of the movable part also have adjustable slots or clear-
ances f, to admit of the longitudinal traverse of the same over the outer end
plate of the fixed part.
The invention is applicable to rubber pedals, and combination rubber and rat-
trap pedals as well as to rat-trap pedals as herein described.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
First In width-adjusting or extending pedals, having a fixed frame and a
supplementary movable frame, traversing the said supplementary and movable
part for varying the width of the pedal by means of a rotating screw, confined
within fixed end bearings, and with which teeth on the said movable frame,
engage, substantially as described and set forth.
Secondly: In width-adjusting or extending pedals, having a fixed frame and
a supplementary movable frame, traversing the said movable part for varying
the width of the pedal by means of a rotatable screw or wormed waist, turning
on fixed bearings of the pedal frame, and with which the toothed or rack edges
of arms or equivalents directed from the said movable part and passing through
guide slots in a sleeve within which the said screw is enclosed, engage, sub-
stantially as described and set forth.
Thirdly: In width-adjusting or extending pedals, the general construction,
arrangement and combination of the parts, substantially as described and set
forth.
