A Brazeless Joint for Improvement in the Mode of and Means for
Connecting Tubes of Cycles, Motor Cycles, and the like.
SAMUEL WALKER, 29, Hendon Road, Sparkhill, Birmingham, Stores Superin-
tendent in Cycle Components Factory, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to the connecting together of tubes of all diameters and
gauges which constitute the frame of all kinds of cycles. In carrying this invention
into effect I make all the lugs of the form known as flush joints or otherwise that
is the lug is turned to fit the inside of the tube so that when tube is placed on the
lug the outside diameter of the tube is flush with outside diameter of the lug or
otherwise and the tube comes square and flush with projection on lug. Hitherto-
fore the tube has been brazed soldered or sweated to lug so as to make a permanent
joint. This invention consists in making a joint which shall be more readily
accomplished give a good sound connection and yet be easily detached. To carry
this into effect I encircle the tube where it fits the lug with a clip so as to grip
the tube on the lug to prevent any sliding or revolving motion of the tube.
drill a hole out of centre through the clip on one side breaking into the tube and
lug and out on the other side of clip. Through this hole I put a cotter pin or bolt
of any form with or without a head parallel or taper and lock it in place by means
of a nut. The clip may or may not be slit through and the lug and tube slit or
not slit a short distance so that by tightening the nut an enormous pressure is
applied to the tube the pin preventing any movement thus obtaining a good sub-
stantial joint. It will be obvious that any form of clip may be used and of any
section but for meatness and for greatest strength a sectional thicker in the centre
and external ends and form with a radius is the most advantageous and also that
any form of pin may be used round, taper, oval with flats, square wedge or a pin
screwed into člip. This invention may not only be applied to frames of cycles, motor
cycles and the like but to anywhere where it is necessary to connect tubes together
at an angle or in the same straight line when a liner in place or the lug would be
used to advantage one clip serving instead of two as is necessary when a lug is
used and tube is jointed at an angle as in the case of cycle frames.

page_text: Superintendent in Cycle Components Factory, 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 improvements in tubular joints, and its object is to
provide an improved method of connecting tubes.to each other or similar junctional
parts.
I attain such objects by the means illustrated in the accompanying drawing, in
which:
Fig. 1, shows in section this my invention as applied to a cycle lug.
Fig. 2, is a view in elevation of my invention.
Fig. 3, is a sectional view of the invention on line A-B (Fig. 2).
Fig. 4, is a view in elevation of the junctional fitting as prepared for the attach-
ment of the tube.
Fig. 5, shows the tube ready for attachment to the junctional fitting..
Similar numbers refer to similar parts throughout the several views.
6, is the junctional fitting, which may be tubular or solid. The outer surface for
a given distance from its end is reduced in diameter to a depth equal to the thick-
ness of the tube 7, so that the latter may be passed thereon up to and against the
shoulder S. Thus the exterior diameter of the lug is equal to that of the tube
so as to form a flush joint.
In the underside of the fitting 6, the cross gap 9, is made to accommodate the
clamping screw pin 10, as hereinafter described, and in the underside of the tube 7,
the cross gap 11, is made to agree with the gap 9, so that when placed together in
position, they shall coincide with each other. The tube 7, may if desired, have
one or more slits 12, made for a short distance along its length, but generally I
find this not to be necessary. 13, is a clip which encircles the tube 7, having the
gap 14, and the screw pin 10, passing through the clip, and through the gaps 9
and 11, so that when the latter is firmly screwed up, the whole is very rigidly bound
together; thus forming a secure tubular joint without brazing or similar methods
now in use.
It will of course be readily seen that the fitting 6, may be substituted by any
other part to which it is desired to attach a' tube.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is;-
1. Making a tubular joint by means of the combination of the fitting 6, having
the end reduced to receive the tube, and with shoulder 8, and gap 9, and the tube 7,
having gap 11, clip 13, clamped by pin 10, passing through gaps 9 and 11, sub-
stantially as set forth and shown.
