PROVISIONAL SPECIFICATION.
Improvements in and in the Production of Velocipede Ball Pedal
Plates.
I, JAMES SIMEON EDGE the younger of Coleshill Street, Birmingham in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
Heretofore, the plates, or the sides of velocipede ball bearing pedals, have been
produced by the process of stamping, or raising metal when in a heated and soft
state, between dies. A said pedal plate consists essentially of a cruciform shaped
piece of metal, with its middle part cupped and inwardly necked, wherein the bearing
balls, and a collar of the spindle respectively work.
The object of my invention is to reduce the cost of production of the said ball
pedal plates, by making them in two or more parts, which are cut out and raised
from sheet metal.
In making a ball pedal plate according to my invention, I proceed as follows.
I cut out from sheet metal, a cruciform shaped blank, and by means of press
or shaping tools, I hemispherically cup inwards, the middle part thereof, and with
the extreme inside part pierced and slightly necked, wherein the lattor the inner part
of the ball bearing collar of the spindle, works.
The bearing balls lie and work within the hemispherical cupped part, and between
the collar as aforesaid.
The opposite horizontal arms of the said plate, constitute the pierced ears which
take upon the ends of the rods of the treads, whilst the vertical arms, form the
horns or foot guides to the pedal.
Disposed and arranged in front of the middle and ear parts of the plate as afore-
said, is a supplementary covering or dust plate, outwardly cupped of the same
hemispherical inside diameter as the cup of the other part, but with its pierced
middle of a less diameter than the cup, and greater than the inner piercing of the
principle plate.
Thus, the ball bearing pedal plate, consists essentially of two coincident plates,
(one without horns) cut out and shaped from sheet metal, and with the concaved
pierced parts, presented to each other, wherein the ball bearings are disposed and work.
The open pierced part of the outside plate is covered by a milled head or nut,
which takes upon the screwed end of a spindle.
I wish it to be observed that the ears of the covering plate are extended to the full
length of the ears of the primary plate, and which like the said primary plate, take
upon, and are affixed to the ends of the rods of the treads or rubbers.
According to another form of my invention, a cruciform blank, with a pierced
middle, is cut out from sheet metal, and within the said pierced part, a cup, raised
from sheet metal, is therein affixed.
The piercing of the plate, is of a size less than the outside diameter of millings upon
the cup, in juxta position to an outside collar.
The cup within the plate is affixed by pressure, which forces the millings thereof,
which are of hard metal, into the soft metal of the plate, and with the collar of
the cup coming against the metal of the boundary edges of the pierced middle.
The independent cup may if necessary be affixed within the plate, by collar-bulging
the cup, on the two sides of the said plate, and then subsequently bardening the metal
of the cup.

Improvements in and in the Production of Velocipede Ball Pedal
Plates.
I, JAMES SIMEON EDGE the younger of Coleshill Street, Birmingham in the County
of Warwick, Manufacturer, 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:-
Heretofore, the plates, or, the sides of velocipede ball bearing pedals, have been
produced by the process of stamping, or raising metal, when the same is in a
heated and soft state, between dies. A said pedal plate consists essentially of a
cruciform-shaped piece of metal, with its middle part cupped and necked, wherein
the bearing balls, and a collar of the spindle respectively work.
The object of my invention is to reduce the cost of production of the said ball pedal
plates, by making them in two or more parts, which are cut out and raised from
sheet metal.
In making a ball pedal plate according to my invention, I proceed as follows-
I cut out from sheet metal, a cruciform shaped blank, and by means of press
or shaping tools, I hemispherically cup the middle part thereof, and with the
extreme inside part pierced and slightly necked, wherein the ball-bearing-collar of
the spindle, works.
The bearing balls lie and work within the hemispherical cupped part, and between
the collar as aforesaid.
The opposite horizontal arms of the said plate constitute the pierced ears, which
take upon the ends of the rods of the treads, whilst the vertical arms form the
horns or foot guides to the pedal.
Disposed or arranged in front of the middle, and ear parts of the plates as afore-
said, are supplementary covering or dust plates, with their middles pierced and
shallow cupped, which when placed upon the front face of the other plate as afore-
said, the said cupped parts and piercings come coincident.
Thus, the ball bearing pedal plate consists essentially of two coincident plates,
(one without horns) cut out and shaped from sheet metal, and with the concaved
pierced parts presented to each other, wherein the ball bearings are disposed and
-work.
.
The open pierced part of the outside plate is covered by a milled head or nut, which
takes upon the screwed end of the spindle.
I. wish it to be observed that the ears of the covering plate are extended to the
full length of the ears of the primary plate, and which like the said primary plate,
take upon, and are affixed to, the ends of the rods of the treads or rubbers.
•
According to another form of my invention, a cruciform shaped blank with a
pierced middle is cut out from sheet metal; and within the said pierced part, a cup
raised from sheet metal is therein affixed.
The piercing of the plate is of a size less than the outside diameter of millings
upon the cup, in juxta position to an outside collar.
The cup within the plate is affixed by pressure, which forces the millings thereof,
which are of hard metal, into the soft metal of the plate, and with the collar of
the cup coming against the metal of the boundary edges of the pierced middle.
The independent cup may if necessary be affixed within the plate, by collar
bulging the cup, on the two sides of the said plate, and then subsequently hardening
the metal of the cup.
Figure 1 of the accompanying drawings represents partly in elevation, and partly
in horizontal section, a velocipede pedal, having hall-bearing pedal plates, made from
sheet metal, and in accordance with one form of my said invention. It will be seen
that each ball pedal plate, or pedal side, is composed of two plates, viz. :-a bearing
and tread carrying plate, and a supplementary, or dust plate.
Figure 2 represents a front end view of the said pedal, and figure 3 is a cross
section upon the dotted lines-A B.

page_text: Figure 4 represents in front elevation, the bearing and tread carrying plates
separately. Figure 5 is an edge view of the same, and figure 6 is a transverse
vertical section taken through the pierced ears.
Figure 7 is a front elevation of the dust plate, figure 8 a vertical section through
the pierced ears of the same, and figure 9 an elevation, showing the shallow sunken
middle part.
Figure 10 represents a vertical section of the two plates, put together, and with
their concaves presented to each other, to form a partly boxed bearing recess, wherein
the ball bearings work, and the coned collar or bearing nut of the spindle, takes.
The same letters of reference indicate corresponding parts in the several figures.
u, a are the treads of the pedal, & the spindle, and c, d the ball bearing pedal
plates, constituting the sides for the pedal, and the part bearings for the balls e,
whilst the other bearings for the balls, are upon the inner and outer ends of the
spindle, viz. the inner end has a solid collar, which works within the cupped bearing
of that end of the pedal, whilst the other and outer end of the said spindle, has a coned
inner end bearing nut f, which screws upon the screwed outer end of the said
spindle, and upon which, a lock nut g also takes, and determines the said bearing nut
having an affixed position, which is common to all pedals.
The treads are connected within the frame formed by the ball pedal plates, by square
rods, with heads h³.
The bearing and tread carrying plate c, shown separately at figures 4, 5 and 6,
consists of pierced ears c², foot guides or horns c³, hemispherical sunken or cupped
middle part c, with middle piercing and neck c; and which said plate is made from
a blank, cut out from sheet metal, and of the configuration of the outside of the
plate to be formed, and then by dies and pressure, and piercing tools, the curva-
ture, hemispherical cupped part; and open neck, are-formed.
This said plate with its hemispherical sunken cupped part, and neck with open
middle, constitute the inner part of the pedal plates, whilst the dust plates, or outer
covering plates, shown separately in figures 7, 8, and 9, are produced in a like
manner to that of the aforesaid plate, viz. :-a sheet metal blank is taken, of the
outside configuration of the plate to be made, and then by dies, pressure, and
piercing tools, the blank is fashioned into the dust plate, consisting of pierced ears d³,
shallow sunken middle part d', and pierced middle part d³.
Although I have represented that the dust or covering plate d, is secured in
front of the primary, or bearing and tread carrying plate c, by the rods passing
through the coincident piercings of them, yet the said outer or dust plates may be
connected to the inner plates by riveting, or by a closing process or processes.
Figure 11 represents partly in elevation, and partly in horizontal section, a
velocipede pedal, with ball-bearing pedal plates, made according to another form of
my invention; and which said ball-bearing pedal plates, or pedal sides, are made
froin sheet metal, by a piercing, raising, and shaping process.
Figure 12 represents an outside edge view of the same. Figures 13, 14, and 15
represent the parts constituting the ball-bearing pedal plates, separately, and figure 16
represents an inside elevation of the said ball-bearing pedal plates, showing how the
metal of the boundary edging of the central hole of the pedal plate, which is of
softer metal than the bearing-cup is forced into the millings on the periphery of the
said bearing cup, and thereby preventing the displacement of the parts one with
another. Figure 17 represents a section upon the dotted lines F G figure 16.
a are the treads of the pedal, the spindle, c, d are the ball-bearing pedal plates,
e are the balls, working within the cupped bearing, f is a bearing and adjustment
nut, and a lock nut.
In the ball-bearing pedal plate, c is the plate, with pierced ears c², foot guides c',
and pierced middle part c³, wherein the cupped ball-bearing d, is affixed by a closing,
or forcing-in process.
Thus, the bearing d, consists of a hemispherical shaped cup, with a neck ď², annular
shoulder d³, and millings d'.

:
The plate c, is of softer metal than the cup d, and is affixed within the piercing c³,
by forcing the metal surrounding the said piercing e, into the interstices, and around
the inillings d', as aforesaid.
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 1
claim is :-
First Making ball-bearing pedal plates, or pedal sides, from cut out sheet metal
blanks, subsequently raised and fashioned into shape, as set forth.
Secondly Making ball-bearing pedal plates, or pedal sides, from raised and
fashioned sheet metal blanks, consisting essentially of an inner plate, with hemispherical
cupped and necked pierced middle part, and an outer plate, with a shallow cupped and
pierced middle part, substantially as described and set forth in figures 1 to 10.
Thirdly: Making ball-bearing pedal plates, from two parts, and from sheet metal,
and connecting the said parts together, by the rods of the treads passing through
coincident holes in them, as set forth in figures 1 to 10.
:-
Lastly Making ball bearing pedal plates, or pedal sides, from a cut-out and
pierced blank, of the configuration required, and a cupped, or a cupped and necked
.bearing, which is affixed within the middle of the said plate, by metal displacement,
collar bulgings, or by other means, substantially as described and set forth.
