PROVISIONAL SPECIFICATION.
Improvements in Means for Strengthening Tubular Parts of Cycle
Frames.
We, WILLIAM ARTHUR LLOYD and JOHN BLYTH, Directors of W. A. Lloyd
and Company Limited, of Lionel Street, in the City of Birmingham, do hereby
declare the nature of this invention to be as follows
1
This invention relates to means for strengthening the junction parts of the
tubular members of cycle frames, and consists in introducing, at the junctions of
the sockets with the tubes, lining plates or stays, of a double T-ended cross section
with the heads preferably curved to the same radius as the inside walls of the
tubes.
Heretofore the connection of a tube to a socket has been made by brazing,
without employing an internal support at the junction of the tube part with the
Bocket.
Thus, in securing the tubular members of a frame together, we employ at the
angles, ordinary sockets, and fit within them and the adjacent part of the tube,
tightly fitting internal and break-joint supports or cross stays of a double T-ended,
I or shallow H cross section, by means of which transverse strength is given to the
framing at the junction parts.
In order to allow the solder to run between the opposed edges of stay, socket
and tube, we propose to make the edges of the stay serrated or channelled or we
pierce the same with small piercings.
To make one stay accommodate itself to varying sized tubes and sockets, the
heads may be fitted with slid-on tubular sleeves or thickening pieces.
Instead of employing double T-ended stays, we may employ stays of a cruciform
or like section with T or plain ends.
The stays may be fashioned from flattened tube, or from suitable pieces of strip
or sheet metal or by stamping or casting.
Further, the stays may be made of hollow and of any suitable section.

We, WILLIAM ARTHUR LLOYD and JOHN BLYTH, Directors of W. A. Lloyd
and Company Limited, of Lionel Street, in the City of Birmingham, 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 relates to means for strengthening the junction parts of cycle

page_text: frames, which are made up from thin-walled metallic tubings, and consists in
introducing, at the junctions of the sockets with the tubes, lining plates or stays,
of a double T-ended cross section with the heads preferably curved to the same
radius as the inside walls of the tubes.
Heretofore the connection of a tube to a socket has been made by brazing,
without employing an internal support at the junction of the tube part with the
socket.
Thus, in securing the tubular members of a frame together, we employ at the
angles, ordinary junction sockets, and fit within them, and the adjacent part of the
tubes tightly fitting internal and break-joint supports or cross stays of a double
T-ended, I or shallow H cross section, by means of which transverse strength is
given to the framing at the junction parts.
In order to allow the solder to run between the opposed edges of stay, socket
and tube, we propose to make the edges of the stay serrated or channelled or we
pierce the same with small holes.
To make one stay accommodate itself to varying sized bores of tubes the heads
may be fitted with slid-on tubular sleeves or thickening pieces.
Instead of employing double T-ended stays, we may employ stays of a cruciform
or like section with T or plain ends.
The stays may be fashioned from flattened tube, or from suitable pieces of strip
or sheet metal or by stamping or casting.
Further the stays may be made of hollow and of any suitable section.
Figure 1 of the accompanying drawing represents a cycle framing with the
thin-walled tube members strengthened or reinforced at their junctions with the
lug sockets by break-joint supports or cross stays constructed according to our
invention.
Figure 2 represents upon an enlarged scale, a section of one of the lugs upon the
dotted line Figure 1, showing more clearly the section of the stay and how the
foot or cross ends of the same take a bearing against and follow the contour of
the inside periphery of a tube and strengthen the same at its junction with a lug
socket.
Figure 3 represents a section of the stay or break-joint support separately.
Figure 4 is a side elevation of the same and Figure 5 a topside plan thereof,
showing how the faces presented to the tubes inside periphery may be serrated to
allow solder to flow between the ends of the stay and the faces of the tube during
brazing. Holes may be drilled or sinkings formed in the stay ends for the same
purpose.
In Figures 1 to 5, a is a cycle frame, a', a³, a³, a², a³, the framing tubes, and
b, b¹, b³, b³, b, b, 6, the sockets of the junction lugs, whilst c, c², c³, c³, c², c³, are the
internal stays or break-joint reinforcements, located and brazed within the said
tubes at their junctions with the said socket and each consisting of a vertical
stay c', with cross ends c, curved to the inside contour of the tube and serrated
at c to facilitate the brazing.
Figure 6 represents an elevation of a modification of our invention in which the
stay is of a cruciform figure, and Figure 7 is a section of the same in position
within a tube.
Figure 8 shows our invention applied to a D sectioned tube, and Figure 9
represents the same applied to a double convex sectioned tube or fork member and
secured in the longer direction of the same, whilst Figure 10 shows such a stay
applied transversely.
Figure 11 is a section of our break-joint stay or internal tube support made
from sheet metal.
We wish it to be understood that our invention is applicable to the strengthening
of thin-walled tubings at parts other than their junctions with the lug sockets of
cycle frames.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. Strengthening or reinforcing the junction parts of cycle frames by
introducing within the tubes at their junctions with the lug sockets, break-joint
pieces or webbed internal stays having T-sectioned head ends preferably curved to
the same radius as the inside walls of the tubes, substantially as described and set
forth.
Secondly. Strengthening or reinforcing cycle tubes or parts of them, by
introducing within them, webbed internal stays having T-sectioned head ends
preferably curved to the same radius as the inside walls of the tubes, substantially
as described and set forth.
