Improvements in Joints for Tubes for Cycles and other purposes.
We, JOHN MARSHALL STARLEY and WILLIAM STARLEY, both of St. Johns
Works, Coventry, in the County of Warwick, Cycle Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manner or method which we adopt for joining or
connecting tubes together, whether in the same line or at an angle thereto, whereby
we are enabled to effect a neat connection having a smooth surface without pro-
jection thereon, rendering the tubes thus joined together particularly capable of
receiving a high polish and of being plated. We are also enabled to connect forks
or other fittings to the tube by the same method of jointing.
In carrying our invention into. effect when constructing a joint piece or when
joining two tubes together which are to lie in a position at right angles to each
other, we cut the circular or open end of one tube to suit the barrel or half or
portion of the circumference of the other tube to which it is to be connected, and we
saw, cut through or pierce the one tube to receive a plate or strip of metal which
we employ as our joint piece. This strip of metal we make of a width slightly in
excess of the diameter of tube, and of a thickness to suit the slot; or saw-cut in a
tube, and in order to effectually retain this joint strip within the tube until the
brazing in of the same has been effected we prefer to pass a pin or pins right
through the tube and its joint piece to serve as rivets. The other tube to whic!
the one tube herein described as having a joint piece or plate within it is to be
connected we also pierce or cut with a rectangular hole or saw-cut to receive the
projecting portion of the joint plate carried from the other tube, so that the joint
plate passes from one tube to the other serving to connect them rigidly together
when the surfaces of the joint and strip are brazed together in any ordinary manner.
For the greater security of the joint strip within the tube forming the T surface
of the connection, we sometimes form the end of the strip with a projecting rivet or
rivets for entering the hole or holes cut within the upper surface of the tube to
receive them and then to be riveted over, or we pass a plain rivet or pin through
the tube and joint plate to secure it in position.
We effect a joint of any tube to another by employing the same system of the
joint strip and slot or saw cuts within the tubes to receive the strip or plate; the
saw cuts or slots being formed at any angle to suit the required inclination of one
tube to the other.
When arranging our improved system of jointing to suit tubes through which a
shaft spindle or rod has to pass, we form the one end of the strip or joint plate
with a hole within it to permit of the same passing through. We modify the form of
our joint strip or plate to suit the sizes or diameters and inclinations of the tubes
which have to be joined together for any particular purpose; and we effect a joint
from a solid bar or rod to a tube by providing the strip or plate as a portion of the
rod or bar or by piercing it and passing the plate through as herein before described
when joining two tubes together.
We do not limit the application of our invention for the improved method of
jointing tubes without external socket pieces or branch pieces, as hereinbefore
described to tubes required for the manufacture of cycles, but we employ the same
system of jointing tubes or rods and tubes by means of a joint plate or strip to
tubes required for any particular ordinary purpose.

Improvements in Joints for Tubes for Cycles and other purposes.
We, JOHN MARSHALL STARLEY and WILLIAM STARLEY, both of St. Johns
Works, Coventry, in the County of Warwick, 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 following
statement:
This invention relates to the manner or method which we adopt for joining or
connecting tubes together, whether in the same line or at angle thereto, whereby
we are enabled to effect a neat connection having a smooth surface without pro-
jection thereon, rendering the tubes thus joined together particularly capable of
receiving a high polish and of being plated. We are also enabled to connect forks
or other fittings to the tube by the same method of jointing.
In the one accompanying sheet of explanatory drawings we illustrate the methods
we employ when carrying our invention into effect.
When arranging for a joint piece or when joining two tubes together which are
to lie in a position at right angles to each other, we cut the circular or open end of
one tube A Figure 1, Figure 2, and Figure 3, to suit the barrel, or half, or portion
of the circumference of the other tube C to which it is to be connected, and we
saw, cut through or pierce the one tube to form a channel a (Figure 1.) to receive
a plate or strip of metal B, which we employ as our joint piece. This strip of
metal B we make of a width slightly in excess of the diameter of tube, and of a
thickness to suit the slot, or saw cut in the tube, and in order to effectually retain
this joint strip within the tube until the brazing in of the same has been effected
we prefer to pass a pin or pins bright through the tube and its joint piece to serve
as rivets. The other tube C to which the one tube herein described as having a
joint piece or plate within it is to be connected, we also pierce or cut with a
rectangular hole or saw cut C' Figure 2 to receive the projecting portion of the
joint plate B carried from the other tube, so that the joint plate passes from one
tube to the other serving to connect them rigidly together when the surfaces of the
joint and strip are brazed together in any ordinary manner.
For the greater security of the joint strip within the tube forming the T surface
of the connection we sometimes form the end of the strip with a projecting rivet or
rivets B2 B3 for entering the hole or holes cut within the upper surface of the tube
to receive them and then to be riveted over, or we pass a plain rivet or pin through
the tube and joint plate to secure it in position.
We effect a joint of any tube to another by employing the same system of the
joint strip and slot or saw cuts within the tubes to receive the strip or plate, the
saw cuts or slots being formed at any angle to suit the required inclination of one
tube to the other as shown at Figure 4 and Figure 5.
When arranging our improved system of jointing to suit tubes through which a
shaft spindle or rod has to pass as shown at Figure 6 and Figure 7 we form the
one end of the strip or joint plate E with a hole e within it to permit of the same
passing through, or we bend the plates round to clear the spindle as shown in
Figure 8.
We modify the form of our joint strip or plate to suit the sizes or diameters and
inclinations of the tubes which have to be joined together for any particular
purpose; and we effect a joint from a solid bar or rod to a tube by providing the
strip or plate as a portion of the rod or bar or by piercing it and passing the plate
through as hereinbefore described when joining two tubes together.
Figures 9, 10 and 11 show our improved method of uniting the carrier or lug F
to the tube members G H. We employ a plate F with projecting horns F1 F for 5
entering saw cuts within G H as hereinbefore described for the other tubes and we
finish off the end of the tube from the ordinary open end as shown at Figure 10

page_text: (which is a section on the line r s Figure 9) to the closed or rounded end as shown
at Figure 11, the end being pressed or knocked down by any ordinary appliance
before the meeting or joining surfaces are brazed together.
We do not limit the application of our invention for the improved method of
jointing tubes without external socket pieces or branch pieces as hereinbefore
described to tubes required for the manufacture of cycles but we employ the same
system of jointing tubes, or rods and tubes by means of a joint plate or strip to
tubes required for any particular ordinary purpose.
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 :-
1. The connection of tube formed parts of cycles and other like frames by
means of flat web or joint plates which enter slots cut within such joining tubes,
substantially as herein described and as illustrated in the accompanying drawings.
2. The construction and arrangement of bicycle and tricycle frames having their
joints formed by means of loose plates or webs which project from one portion or
member of the frame and enter into a saw cut or slot formed in another portion or
member of the frame.
