Improvements in the Construction of Joints for the Framework and

•
I, ARTHUR COMINGS HIDE, of Ivy Villa, Harewood Road, Merton, in the
County of Surrey, Manager of Works, do hereby declare the nature of this
invention to be as follows:-
My invention relates to an improved construction of the joint pieces made out of
sheet metal and used in the construction of the frame and other parts of cycles, and
it consists in so shaping these pieces that their abutting edges interlock with each
other.
Hitherto these junction pieces have either been inserted in the tubular members
of the frame or if they have been placed outside or over the members of the
frame they have had tubular collars placed over them to keep their abutting edges
together while the joint has been brazed, but according to my invention the joint
pieces can be placed outside or over the tubular or other members of the frame
without the use of tubular collars.
According to my invention 1 shape the abutting edges of the joint pieces so that
they can be dovetailed together when the said edges meet, the dovetailed pieces or
pins being set back so that the edges of the piece or pieces can be brought
together round the member of the frame to which it is to be fixed, and the said
dovetailed pieces or pins are then hammered or pressed inwards to engage with the
dovetailed recesses.

COMPLETE SPECIFICATION.
Improvements in. the Construction of Joints for the Framework and
other Parts of Cycles.
I, ARTHUR COMINGS HIDE, of Ivy Villa, Harewood Road, Merton, in the
County of Surrey, Manager of Works, 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 an improved construction of the joint pieces made out of
sheet metal and used in the construction of the frame and other parts of cycles,
and it consists in so shaping these pieces that their abutting edges interlock with
each other.
Hitherto these junction pieces have either been inserted in the tubular members
of the frame or if they have been placed outside or over the members of the frame
they have had tubular collars placed over them to keep their abutting edges
together while the joint has been brazed, but according to my invention the joint
pieces can be placed outside or over the tubular or other members of the frame
without the use of tubular collars.
According to my invention I shape the abutting edges of the joint pieces so that
they can be dovetailed together when the said edges meet, the dovetailed pieces or
pins being set back so that the edges of the piece or pieces can be brought

page_text: together round the member of the frame to which it is to be fixed, and the said
dovetailed pieces or pins are then hammered or pressed inwards to engage with the
dovetailed recesses.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing which shows-by way
of illustration a T-shaped socket or joint piece constructed according to my
invention, the several Figures 1, 2, 3, 4, 5 and 6 showing the socket or joint piece
in the several stages of its construction.
In the several views similar parts are denoted by like letters of reference.
In constructing a T-shaped socket or joint piece I take a suitably shaped blank
and stamp or press it into the shape shown by Figures 1 and 2, alter which I bend
or block it into the shape shown by Figures 3 and 4 when it is ready for use.
The abutting edges a, a, and a', a', are shaped to interlock the one with the other,
the teeth and indents being shaped to fit each other. The teeth are throughout
the stages indicated by Figures 1, 2, 3 and 4 left in their original positions with
respect to the body of the piece so that they stand out clear of the indents c when
the edges a, a, and a', a', are brought together as shown by Figures 3 and 4.
In use the tubes or the like are inserted in the two parts of the socket or joint
piece and the edges a, a, and a', a', are brought together to clip the said tubes or
the like and the teeth b are then hammered or pressed down to engage with the
indents e as shown by Figures 5 and 6 and so hold all the parts securely together
while the joints are brazed.
The teeth and indents may be of a dovetail or other suitable shape.
I am aware that metal tubes have been constructed from strips of sheet metal
having interlocking edges and I therefore do not broadly claim the uniting of the
two edges of a piece of sheet metal by means of interlocking joints as this method
of construction only lends itself to such articles as can be stamped or blocked into
the finished shape after the edges are secured together which is not possible with
the joints in the frames of cycles.
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 :--
The improved construction of joints for the framework and other parts of cycles
substantially as set forth and illustrated by the accompanying drawing.
