Improvements relating to Brazing or Hard Soldering.
I, WILLIAM RICHARD BOWERS, Foreman, of 63, Nelson Road, Aston, Birming-
ham, do hereby declare the nature of this invention to be as follows:-
This invention relates to brazing or hard soldering and is more especially applic-
able for the brazing of the constituent tubes of cycle frames to the brackets or lugs
employed thereon.
The invention has for its objects to effect a perfect brazing joint, to minimize
the amount of filing necessary to produce a smooth surface around the joint
after brazing, while further to prevent scale from falling through the tubes.
The invention consists in the use of a thin brass liner or ferrule within the
socket or recess into which the tube is to be brazed, or upon the tube or part which
is to be secured within the socket, such liner or ferrule being preferably provided
of cup shape so as to completely envelope the extremity of the tube to be brazed, or
to completely fill the socket or recess in which the tube or part is to be secured
In carrying the invention into effect in the provision of a brazing joint, a thin
liner or ferrule of cup shape is produced from thin brass by stamping from blank
metal or by drawing as a tube, the liner or ferrule being cut therefrom to the
length required.
In the employment of such a liner or ferrule for effecting a joint between the
tubes of a cycle frame and say the axle bracket of the frame, the smooth bore of the
socket is preferably cleaned with acid, and flux such as borax applied. The thin
brass liner is inserted within the recess, and the extremity of the tube to be con-
nected is filed smooth and cleaned and applied with flux being inserted into the
socket, the liner or ferrule being intermediate.
The process of brazing may be effected in the usual way, either upon the hearth
or with a blow pipe.
It will thus be understood that in accordance with the present invention the use
of brass filings is obviated, and it will be understood that by the substitution of
a brass liner a perfect joint may be secured which minimizes the work of filing,
and prevents any scale in the inside of the tube falling through.
Dated this 14th day of June 1808

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
-
This invention relates to brazing or hard soldering and is more especially appli-
cable for the brazing of the constituent tubes of cycle frames to the brackets of lugs
employed thereon.
The invention has for its objects to effect a perfect brazing joint, to minimize
the amount of filing necessary to produce a smooth surface around the joints
after brazing, while further to prevent scale from falling through the tubes.
The invention consists in the use of a thin brass liner or ferrule within the
socket or recess into which the tube is to be brazed or upon the tube or part which
is to be secured within the socket, such liner or ferrule being preferably provided
of cup shape so as to completely envelop the extremity of the tube to be brazed or
to completely fill the socket or recess in which the tube or part has to be secured.
The invention is illustrated in the accompanying drawings in which Figure 1
represents in section the axle bracket of a cycle frame, and Figure 2 represents in
section a liner or ferrule employed according to the invention, while Figure 3 is
a plan thereof.
Figure 4 represents a section of tubular ferrule that may be employed.
In carrying my invention into effect in the provision of brazing joint, a thin
liner or ferrule A of cup shape is produced from thin brass by stamping from blank
metal or by drawing as a tube, the liner or ferrule A being cut therefrom to the
length required.
In the employment of such a liner or ferrule A for effecting a joint between
the tubes of a cycle frame and, say, the axle bracket B of the frame the smooth
bore of the socket E may be cleaned with acid and flux such as borax is applied.
The thin brass liner A is inserted within the recess of the socket E and the ex-
tremity of the tube to be connected is filed smooth and cleaned and applied with
flux; it is then inserted into the socket E, the liner or ferrule A being intermediate.
The process of brazing may be effected in the usual way either upon the hearth
or with a blow pipe.
It will be understood that in accordance with the present invention the use
of brass filings is obviated and by the substitution of a brass liner a perfect joint
is secured which minimizes the work of filing and prevents any scale in the inside
of the tube falling through.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In brazing or hard soldering the use of a thin brass liner or ferrule for
the purpose and substantially as described and illustrated.
2. In brazing or hard soldering the use of a thin brass liner or ferrule applied
within the socket or recess into which the tube or part is to be brazed or upon
the tube or part which is to be secured within the socket substantially as described.
