Improvements in and in the Manufacture of Certain Parts of
Cycle Pedals.
I, ALFRED WHITEHOUSE, Manager of the St. George's Engineering Company
Limited, of Pope Street, in the City of Birmingham, Cycle Manufacturers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of cycle pedals, and
in the manufacture of certain parts of them, and consists, in the one part, in a
new adjustment for the bearings of pedals, and a lock for the same; in another
part, in a flush end plate dispensing with end caps, and in a further part, in making
the end bearing sockets or races and the framing in two transverse sectional parts.
In carrying out one form of that part of my invention relating to adjustment
and locking means for the bearings of pedals, the outer end of the spindle, pass-
ing axially through the centre or waist of the pedal, has an annular channel, groove
or ball bearing race formed around it, and takes within a cylindrical socket or
chamber, formed integrally or otherwise upon the inner side of the outer end
plate, the other side of which is completely closed and is left quite smooth or flush
or has no outstanding collars, dust caps or the like as are common to ordinary
pedals. The inside of the said closed socket or boxed-in bearing chamber is inside
screwed to receive a like outside wormed cup or barrel, screwing therein for adjust-
ment and having its inward edge coned or otherwise formed with a part ball race,
between which and the groove or annular race on the spindle end the anti-friction
balls of the bearing come. The outward part of the adjusting cup has flats or
facets at parts, whereby its rotation for adjustment inwards or outwards by a
spanner or similar instrument is facilitated, whilst it is plain bored axially through-
out its length to take the plain outer end of the pedal waist or centre which sockets
truly or make a dust-proof fit therein and is carried at the inner end by the other
end-plate of the pedal, the usual ball race being formed at the junction of the two
parts for the reception of the inner spindle bearing.
Taking upon the outwardly extending end of the adjusting barrel or cup is a
lock or ring nut, which, when screwed up tight against the opposed end of the
socket or bearing chamber, locks the cone in its adjusted position within the said
chamber.
The inner end of the spindle is provided with a collar which lies flush within
a corresponding sinking in the outer face of the end plate.
According to another form of this part of my invention, the inside walls of
socket or box chamber are plain for receiving the plain outside periphery of the
forward end of the adjusting cup or barrel, which sockets therein, the inside of the
axial hole through which is screwed and takes upon the like screwed outside end
of the waist, which also carries, inwards of the cup, a lock nut capable, when screwed
home against the end of the cup, of making or locking the same fast within its
adiusted position.

Improvements in and in the Manufacture of Certain Parts of
Cycle Pedals.
I, ALFRED WHITEHOUSE, Manager of the St. George's Engineering Company
Limited, of Pope Street, in the City of Birmingham, Cycle Manufacturers, 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 follow-
ing statement:-
This invention relates to improvements in the construction of cycle pedals, and
in the manufacture of certain parts of them, and consists, in the one part, in a
new adjustment for the bearings of pedals, and a lock for the same; in another
part, in a flush end plate, whereby the employment of end caps is obviated, and in
a further part, in making the end bearing sockets or races and the framing in
two transverse sectional parts.
Figure 1 of the accompanying drawings represents a longitudinal vertical section
of a cycle pedal, having a flush outer end plate, and being provided with bearing
adjustment and lock and with the framing and end bearing sockets being made
in two sections, in accordance with one form of our invention.
Figure 2 is a side elevation of the said pedal, which is of the rat-trap type.
Figure 3 is an enlarged section of the outer end bearing of the pedal, show-
ing the means for adjusting, and locking the adjustment of the bearings.
Figure 4 is a plan, with a part of the framing in transverse longitudinal section,
of the said pedal.
Figure 5 is an elevation of the outer end of the pedal, showing the flush end
plate, and Figure 6 is an elevation of the inner end.
Figure 7 is a longitudinal section, similar to Figure 1, but showing the whole
of the parts of the bearings and the transversely divided sectional halves of the
framing, separated or dis-assembled from one another.
Figure 8 is a transverse section of the pedal, upon the dotted line *, Figure 4.
The same letters of reference indicate corresponding parts in the said Figures 1
to 8 of the drawings.
In the improved construction of pedal embodying my invention, as represented
in the aforesaid figures, the outer end a¹, of the pedal spindle or axis a, passing

page_text: axially through the centre waist or tubular sleeve b, of the pedal, has an annular
channel, groove or ball bearing race a³, formed around it, and takes within a
cylindrical socket or chamber c¹, formed integrally or otherwise upon the inner
side of the outer end plate 2, of the framing c, the other side of which is com-
pletely closed and is left quite smooth or flush or has no outstanding collars, dust
caps or the like as are common to ordinary pedals. The inside of the said closed
socket or boxed-in bearing chamber is screwed to receive a like outside wormed
cup or barrel d, screwing therein for adjustment and having its inward edge d³,
coned or otherwise formed with a part ball race, between which and the groove
or annular race on the spindle end of the anti-friction balls e, of the bearing come.
The outward part of the adjusting cup d, has flats or facets ³, at parts, whereby
its rotation for adjustment inwards or outwards by a spanner or similar instru-
ment is facilitated, whilst it is plain bored at d, axially throughout its length
to take the plain outer end 61, of the pedal waist or centre b, which sockets truly
or make a dust-proof fit therein and is carried at its inner end by the other end
plate 3, of the pedal frame, the usual ball race c, being formed adjacent to the
junction of the two parts for the reception of the inner spindle bearings c.
Taking upon the outwardly extending part of the adjusting barrel or cup is a
lock or ring nut f, which, when screwed up tight against the opposed end of the
socket or bearing chamber, locks the cone-ended cup in its adjusted position
within the said chamber.
The inner end of the spindle provided with a collar a³, which lies flush within
a corresponding sinking, in the outer face of the end plate c³.
The pedal frame may be made as usual of separate side and end plates, or may
be made up as follows:-
The inner and outer end plate c³, ³, are respectively made integral with two
opposed half-length side-plate sections c7, 8, with the meeting edges c, c¹0, of the
half lengths or half sides being shamfered and shouldered and arranged to over-
lap so as to admit of them being connected together by screw pins cll, or by
rivetting or otherwise.
The inner end plate may have only the ball race or annular sinking made
integral with it, or it may have both the waist and ball race formed in one piece
with it, whilst the outer end plate may have the socket or cylindrical ball chamber
made integral therewith, or the said socket may be made separately and attached
in position by screwing, rivetting or otherwise.
Figure 9 represents a rat-trap pedal in which the bearing adjustment and
locking means is constructed according to a modification of my invention.
Figure 10 is a longitudinal vertical section thereof, and
Figure 11 is a topside plan of the said pedal.
In this modification of my invention, the inside walls of socket or bearing
chamber c, are plain for receiving the plain outside periphery of the forward
end d¹, of the adjusting cup or barrel d, which sockets therein, whilst the inside
of the axial hole, through the said adjusting cup is screwed and takes the
upon
like screwed outside end 61, of the tubular waist b, which also carries, inwards
of the cup, a lock nut f, capable, when screwed home against the end of the cup,
of making or locking the same fast in its adjusted position. The waist or barrel
may be made either as a separate element, or in common or integral with the inner
end plate.
Figure 12 represents in longitudinal vertical section, Figure 13 in plan and
Figure 14 in part section upon an enlarged scale, a rubber pedal with the bear-
ings and adjustment constructed according to another modification of my inven-
tion, in which the adjustable bearing cup or barrel d, is provided with a milled
collar d', at its outer end for facilitating its adjustment, whilst instead of closing
in the bearing chamber c¹, by an integral end as represented in the previous forms,
I employ a removable disc, c", which constitutes a locking device for the bearing
cup
and is wormed at its edges to screw into the interiorly threaded mouth of the
said cap, key spanner sinkings c¹, being provided in the outer face for worming

page_text: the same into and out of position. Instead of the bearing race being formed at
the end of the cup or sleeve, as in the preceding arrangement, the interior of the
said sleeve is provided with an annular bearing collar d', having a coned surface d³,
between which and the ball race a³, of the spindle a, the balls e, of the inner end
bearing come.
Thus, in making the adjustment of the bearings, the cup or sleeve is screwed
into the bearing chamber to the required extent so as to take the coned internal
collar up to the proper distance from the balls and then the locking disc is screwed
into the chamber from the outside until it abuts against the inner end of the said
cup so that the disc and cup mutually lock one another and the cup is prevented
from worming further inwards and thus binding upon the balls.
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 In cycle pedals, enclosing a ball-raced end of the spindle in a boxed-
in chamber or socket, located upon the inner side of an end plate of the pedal
frame and adapted to receive an adjustable sleeve or barrel, which is ball-raced or
coned and constitutes the adjustable element of the bearings, and between which
and the ball race on the spindle, ball bearings, are disposed, the whole of the
parts being locked together by a lock nut or disc.
Secondly: In cycle pedals, enclosing the outer and ball raced end of the
spindle in a boxed-in or closed socket or chamber located upon the inner side of
the outer end plate, and being inside screwed to receive an outside screwed and
cone ended or ball-raced adjustable barrel, sliding over a plain part of the tubular
waist and receiving a lock nut by which the said sleeve is locked in adjusted
position to the said chamber, and by which arrangement a flush outer end plate
is obtained, substantially as described and set forth in Figures 1 to 8.
Thirdly-In cycle pedals, enclosing the outer and ball raced end of the spindle
in a boxed-in or closed socket or chamber disposed on the inner side of the outer
end plate and adapted to receive an adjustable cone-ended sleeve or barrel screw-
ing on a wormed part of the tubular waist and locked in its adjusted position by
a lock-nut, also screwing on the said waist, substantially as described and set
forth in Figures 9, 10 and 11.
Fourthly: In cycle pedals, enclosing the outer and ball raced end of the
spindle in an open ended and internally wormed socket, carried by an end plate
of the pedal frame and adapted to receive an adjustable sleeve or cup, provided
with an internal ball race and locked into an adjusted position by a locking disc
screwed into the said cup, substantially as described and set forth in Figures 12, 13
and 14.
