Improvements in Pedal Axle Brackets of Velocipedes, and in the
Connections of the said Brackets.
I, RICHARD GREEN of the Lion Cycle Company, of Broad Street in the City
of Birmingham, Cycle Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the construction or arrangement of that part of
velocipedes, and particularly safety bicycles, called the bracket, wherethrough the
pedal axle takes, and which said bracket, consists of a tubular and horizontal body
part, having upon the front side of the middle of the waist part of it, a truncated
socket connection, whilst directed through the middle part of the top side of the
said waist, is a second socket or recess, wherein the lower end of the erect part of
a framing next to the rear wheel of a machine, takes, whilst the other and front
socket, receives the lower end of an obliquely directed frame rod, terminating in
the steering post mounted upon the front fork."
In this connection of framing, members, as aforesaid, constituting a part of the
general framing, meet at a point outside the centre or middle of the bracket,
hence an unequal distribution of the weight of the framing of the machine.
My invention has for its object, the arrangement of the said bracket, so that the
weight of a machine shall be evenly distributed, by being centralized or directed
towards the middle or axial part of it.
Besides equally distributing the weight of a machine, the connections with the
bracket are strengthened.
In carrying out my invention, the body part of the bracket is made hollow or
tubular, and with expanded ends or ball bearing ends, within which latter the
antifriction means in the form of ball bearings, roll.
The front and fore middle part of the waist of the said bracket, has directed
from it, a truncated socket or shouldered sleeve, which takes the lower end of the
oblique member, forming the bottom rod of a diamond frame.
The right hand side of the middle of the waist of the said body part, has
directed from it, a bossed eyed socket or recessed snug, wherein or whereupon the
lower end of the upright member of the said diamond frame, takes, and is there
brazed alike unto the radially directed and stay member of the frame as
aforesaid.
Thus, the bracket, which is the suspended bearing of the pedal axle or axis, has
disposed upon the two opposite sides of the waist part of it, outstanding hollow branches
or hollow lugs, for taking or carrying the members of the framing aforesaid.
Upon the two opposite sides of the right hand lug, or bossed eye, are supple-
mentary frame lugs, which carry the fork and horizontally directed framing part
of the rear wheel.
By disposing the carrying lugs or branches of the framing upon the two opposite
sides of the bracket, as aforesaid, a considerable mechanical advantage is
attained.
prefer to make the said bracket and its connection lugs by stamping or drop
forging, by first taking a solid blank of metal, and when in a soft state, by
successive blows, fashion the same into the shape required.
It is then finished by boring, turning and finishing.

Improvements in Pedal Axle Brackets of Velocipedes, and in the
Connections of the said Brackets.
I, RICHARD GREEN, of the Lion Cycle Company, of Broad Street in the City
of Birmingham, Cycle 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 :-
This invention pertains to the pedal axis, bearing brackets of safety and like
velocipedes.
The said bracket, as ordinarily constructed, has the socket member, which
carries the rear and nearly upright member of a diamond frame, disposed
immediately above a vertical line directed through the axis of the body of the
said article, or in other words, the axis of the socket when projected downwards,
intersects or thereabouts, the axis of the bracket.
The framing members at their lower ends, are united together by the said
brackets, which besides constituting a pedal axis bearing bracket, also forms a
junction for the frame members.
The object of my invention is to impart increased rigidity to the general
framing, and to distribute more evenly, the weight of the same.
In carrying out my invention, the body part of the bracket is made hollow or
tubular, and with the ends of the same formed into recessed heads, wherein the
anti-friction balls roll, between the inside surfaces thereof and the cones on the
axle.
Branching upwardly from the middle of the waist of the front side of the said
bracket, is a truncated socket or shouldered sleeve, wherein the lower end of the
oblique member, forming the fore and bottom rod of a diamond frame, takes.
Directed from the middle of the other side of the waist of the said bracket, is a
bossed eyed socket or ring snug, wherein the lower terminal end of the nearly
upright member of the diamond frame takes, and is there brazed, alike unto the
stay member of the frame as aforesaid.
Thus, the bracket, which is the connecting junction of the framing members,
has disposed or located upon the two opposite sides of its waist or body part,
hollow branches or short arms, with sockets or ring formations adapted to take or
carry the lower ends of the principle framing members.
Directed upon the two opposite sides of the bossed eye or ring snug at the rear
side of the waist of the bracket, are nearly horizontal-directed rear-wheel fork
lugs, upon which the tubular ends of the fork branches of the said wheel take.
Figure 1 of the accompanying drawing represents in horizontal section, partly
in elevation, a pedal axis bearing bracket, constructed and arranged according to
my invention.
Figure 2 represents a safety bicycle, fitted or provided with my said bracket.
Figure 3 is a vertical section upon the dotted lines A. B. Figure 1.
Figure 4 is a like vertical section of the said bracket Figure 1, but upon the
dotted lines C. D.
In Figures 1 to 4, a is the bracket, a' the waist part, and a³ the recessed and
enlarged cupped ends, which form the races for the ball bearings to roll within,
b is a truncated socket or shouldered sleeve, directed upwardly from the front side
of the middle of the waist of the said bracket, and wherein, the lower end of the
under oblique member of a diamond frame takes and is there brazed.
Directed from the back of the middle. of the waist of the said bracket, is a
bossed eye or ring lug d, wherein the lower end e, of the nearly upright frame
member e, takes, and is there brazed. fare solid rear-wheel fork lugs, upon which
the ends g, of the hollow branches 9, of the forks of the rear wheel take, and are
there bized.

page_text: The said bearing bracket, with its cognate parts, in the form of sockets, bossed
eyes and solid lugs, is made solid by drop forging or stamping.
By disposing the sockets or hollow lugs b, and d, upon the two opposite sides of
the said bracket, as represented, a great mechanical advantage, in the balancing
and distributing of the weight of the frame is obtained over ordinary brackets
where the bossed eyed ring d, is disposed immediately above the middle of the
waist of the bracket.
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 pedal axle bearing brackets, disposing or arranging the socket, or
the ring lug member, wherein the lower end of the back and nearly upright
member of a diamond frame takes, at the back of the body, or rearwardly of a
vertical line directed through the axis of the said body, as set forth.
Secondly-In a pedal axle bearing bracket, with the socket, eye and lug
members disposed and arranged substantially as set forth.
