Improvements in the Construction and Arrangement of Cycle
Framings.
I, JOHN WILLIAM KENNELLY of 7 Barnabas Road, Leicester, in the County
of Leicester, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction and arrangement of the parts of cycle
frainings, particularly for safety bicycles; and other like two wheeled velocipedes,
and which said invention has for its object, increased strength in construction,
combined with lightness.
The invention consists primarily in crossing the horizontal and oblique members,
commonly called the bottom and top neck tubes, directed from the top and bottom
ends of the neck or steering post, and which terminate at the junction of the pedal
axis bracket, and upper part of seat tube or member respectively.
In carrying out my invention in connection with a safety bicycle frame, I connect
the lower end, or lower terminal part of the steering post, which rakes forwardly,
or is directed obliquely to the axis of the front wheel, to the upper part of the seat
tube or seat member, which curves downwardly, and terminates on the top side of
the pedal axis. bracket, by two horizontal or nearly horizontal parallel directed
members, or bottom neck tubes, which are separated from each other by a distance
not greater thau, or about equal to the diameter of the top neck tube, which pro-
ceeds obliquely downwards from the upper end of the steering post, passes between
the two horizontal members as aforesaid, and terminates at the junction of the
lower end of the seat tube with the pedal axis bracket.
The crossing of the front parts of the members, takes place at a short distance
from their connections with the upper and lower ends or parts of the steering post,
which is an obliquely directed tube or sleeve wherethrough the steering axis sur-
mounting the forks of the front wheel, passes.
The rear part of the framing, consists of an ordinary fork, with the branches or
side members of it, directed and expanding outwardly from the rear side of the
pedal axis bracket, and with the ends, middle gapped as usual, and above, or
proceeding from the top sides of which ends, are obliquely directed hanger stays,
connected to the seat tube or pillar under, or in juxta position to the lug of the
rear end of the bottom neck tubes or parallel members.
Thus we have a diamond frame, terminated at its lower end by a pedal axis
bracket, and at its fore and upper part by the post or neck, with the forward ends
of the respective members, crossing each other at a short distance from it, and
making, as it were, a secondary enclosed figure of a triangular shape, coming in
vance of the said diamond shape of the general frame, which is bisected by the
seat tube.
adva
The connection lug at the forward end of the parallel members, consists of an
eye, with branches directed rearwardly of it; the former embraces the lower end
of the post, while the branches take into the fore ends of the tubes of the latter.
The rear lug of the parallel members, is alike that on the fore part of the
machine, but with the eye taking around the pillar upper end of the seat tube.
The lug at the upper end of the top neck tube, is a socket eye, with a branched
end taking into a tube, or the lower end of the said tube is connected to a branched
lug, made in one stamping with the pedal axle bracket, and common to both the
seat tube and the top neck tube.
As a modification of my invention, I may employ in substitution of a single top
member, two tubes running in parallel and oblique directions, aud at short distances

page_text: apart, and with a single tube taking between them, to take the place of the two
horizontal and separated bottom tube members as aforesaid, so that the primary
part of the framing consists of parallel and side by side oblique members, with a
single horizontal member going between the aforesaid at a short distance from
their forward connections with the post, to which they are connected.
Instead of the ends of the members taking or fitting upon branches of lugs, con-
nected to the respective parts of the framing, the said ends may pass through
eyes or holes made through branches carried by lugs, bossed eyes or other like
connections.
Frames thus constructed, are endowed with considerable strength combined with
lightness, and further, that the frame is both flexible or springy, and on a rider
mounting, imparts a forward movement to the front wheel.

COMPLETE SPECIFICATION.
Improvements in the Construction and Arrangement of Cycle
Framings.
I, JOHN WILLIAM KENNELLY, of 7 Barnabas Road, Leicester, in the County
of Leicester, Engineer, 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 :-
My invention relates to improvements in the construction of the frames of safety
and other cycles, and has for its object, obtaining strength with lightness, imparting
steadiness and rigidly to the pedal axle bearing bracket, distributing more evenly
the weight of a rider, and further in reducing the tendency to cross-straining of the
frame members, thereby preventing rupture or fracture.
My said invention consists primarily in crossing the horizontal and oblique
members, commonly called the bottom and top neck tubes, directed from the top
and bottom ends of the neck of the steering post, and which said tubes or members
terminate at the seat tube carrying the pedal-axle-bracket at its lower end.
In carrying out my invention in connection with a safety bicycle frame, I connect
the lower end or the lower terminal part of the steering post neck, which rakes
forwardly, and down which the steering post passes, in a ball head. to the upper
part of the seat tube or seat member, which curves downwardly, and terminates
on the top side of the pedal axis bracket, by two horizontally directed or nearly
horizontally directed parallel members, or bottom neck tubes, which are separated
from each other by a space, greater than or equal to the diameter of top neck tube,
which proceeds obliquely downwards from the upper end of the steering post neck,
passes between the two horizontal members as aforesaid, and terminates at the
junction of the lower end of the seat tube member with the pedal axis bearing
bracket.
The crossing of the front parts of the members, takes place at a short distance
from their connections with the upper and lower ends or parts of the steering post
neck aforesaid.
The rear part of the framing consists of an ordinary fork, with the branches or
side members of it, directed and diverging outwardly from the rear side of the
pedal axis bracket, and with the ends middle gapped as usual, and above or pro-
ceeding from the top sides of which ends, are oblique hanger stays, connected to the
seat tube or pillar, under or in juxta-position to the lug of the rear end of the
bottom neck tubes or double rod members.
Thus, we have a diamond frame terminated at its lower end by a pedal axis

page_text: bracket, and at its fore and upper part by the post neck, with the forward ends of
the respective members, crossing each other at a short distance from it, and making
as it were a secondary enclosed figure of a triangular shape, coming in advance of
the said diamond shape of the general frame, which is bisected by the seat tube.
The connection lug at the forward end of the parallel members, consists of an
eye, with branches directed rearwardly of it, the former embraces the lower end
of the post, while the branches take into the fore ends of the tubes of the latter.
As a modification of my invention, I may employ in substitution of a single top
neck member, two tube members running in parallel and oblique directions, and at
short distances apart with a single tube member taking between them, and taking
the place of the two horizontal and separated bottom tube members as aforesaid,
so that the primary part of the framing consists of parallel and side by side oblique
members, with a single horizontal member going between the double tube
members.
Instead of the ends of the members taking or fitting upon branches of lugs,
connected to the respective parts of the framing, the said ends may pass through
eyes or holes made through branches carried by the lugs, bossed eyes or other like
connections.
Figure 1 of the accompanying drawings, represents in side elevation a safety-
bicycle framing, constructed, and the parts of the same arranged, and combined,
according to one form of my invention.
Figure 2 represents a vertical cross-section of the said framing, on the dotted
lines A. B. Figure 1, showing how the single and oblique spanning or bridging
member of the one part, passing between double spanning members of another part,
and which said last named members together constitute, as it were, a trussed beam,
hence great strength and rigidity.
Figure 3 represents a topside plan of Figure 1, showing more clearly the dis-
positions of the members with respect to each other.
The same letters of reference indicate corresponding parts in the several figures.
Circumferentially embracing the lower part of the steering post or steering rod
of a machine, and contiguous to the crown located at the junction of the fork with
steering post or rod as aforesaid, is a hollow neck or sleeve, raking rearwards
from its lower end, and forming the fore part frame member of a ball head
machine.
b is a seat tube or rest member directed at the back part of the frame proper,
and which is terminated at its upper end by the seat or pin bar, or other like
seat connection, and at its lower end by the pedal axis bearing bracket c.
Directed horizontally or nearly so, from the upper part of the seat or rest
tube b, and terminating in the lower part of the neck or sleeve a, are two tube or
rod span members d, d, running parallel (or nearly so) to each other, and disposed
at short distances apart.
Passing between the said double rod members d, and with the extreme outer
ends of the same, terminating in the upper part of the said neck or sleeve a, and
the pedal axis bracket c, respectively, is an obliquely directed and single tube or
rod spanning member e, which with the other members constitute the primary
framing of the machine.
The after or back wheel framing consists of tubes or rods f and g, terminating
rearwardly in a bracket or junction piece h, and forwardly in the rest member b.
As a modification of my new or improved aforesaid framing, the double bridging
or spanning members tubes or rods d, may be replaced by a single rod or tube
member, directed between and used in conjunction with, two oblique and separated
tube or rod members, arranged side by side, and taking the place of the single
member e.
Figure 4 represents my improvement or improvements applied to the framing of
a ladies safety bicycle.
a is the hollow neck or sleeve part encircling the steering post, h is the seat tube
or rest rod, c is the pedal axis bearing bracket, having a depending extension &³,

page_text: directed from its lower side, e is an oblique and single spanning tube or rod
member, directed from the front part of the extension c, to the top of the hollow
neck or sleeve a.
The other spanning or bridging part of the framing, consists of double tube or
rod. members d, running side by side, and with the single member e, coming or
passing between them, and also with the said dual members d, terminating at the
pedal axis bearing bracket e, and lower part of neck or sleeve a respectively. The
positions of the spanning members may be changed; thus if desired two side by
side tube or rod spanning members may be replaced by a single spanning member d,
and a single spanning member may be employed in lien of the double members.
My said improvements are equally applicable to machines having heads 'con-
structed other than as described and represented.
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 safety bicycle and velocipede framings, making up the middle of the
same, or that part lying between the post or neck, seat or rest and bracket
members, a, and c, of double tube or rod bridging members d, d, and a single
tube or rod member e, the latter member e, coming or passing between, and crossing
the former double members d, d, substantially as described and set forth.
Secondly: In safety bicycle and velocipede fore part framing, making up the
same essentially of post or neck and seat or rest members, with the middle framing
part between, composed of double tube or rod members, and a single tube or rod
member, and with the ends of the said double tube or rod members, and the single
tube or rod member, terminating in the upper and lower parts of the posts or neck a,
the upper part of seat or rest tube or rod b, and in the pedal axis bearing bracket c
respectively, substantially as described and set forth.

arrangement of the parts of the same, or the fore part framing of the same, as
described and set forth in Figures 1, 2, and 3.
Fourthly In the framing of a ladies' safety cycle, or the fore part framing of
the same, the general construction and arrangement of the parts substantially as
described and set forth in Figure 4.
