COMPLETE SPECIFICATION.
Improvements in Brazing Apparatus applicable to Portable Forges.
I, RICHARD JONES, of 6, Croydon Street, Bryanston Square, in the County of
London, Engineers Fitter, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
-
My invention relates to improvements in brazing apparatus applicable to port-
able forges, which consists of a blow pipe attached to a universal joint connected
to a vertical tube between the bellows and the tue iron.
And in order that my invention may be thoroughly understood I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a back elevation of the half ball joint.
Fig. 2, is a side elevation of Fig. 1, the dotted lines indicate the blast way.
Fig. 3, is a top view of the half ball joint, the dotted lines indicate the con-
struction of the interior mechanism, the small arrows indicate the travel of the
gas and the large arrow the blast.
Fig. 4 is an elevation of a portable forge with the apparatus attached.
Fig. 5, is a front elevation of the valve.
Fig. 6, is a side elevation.
Fig. 7, is a plan of the valve.
Fig. 8, is a vertical section of the inside cup a¹, drawn to an enlarged scale.
Fig. 9, is a side elevation of Fig. 8.
Fig. 10, is a plan of the cup at e¹.
Fig. 11, is a plan of the inside of the half ball joint & showing the gas way
holes f¹.
Fig. 12, is a plan of the cup at h¹.

In carrying my invention into practice I connect to the bellows b an elbow f
with a short piece of barrel vertically and to this said barrel I connect a tee y
with a tube leading to the tue iron c. To the tee
elbow gl a vertical tube which is provided with a
said flange I fix by bolts a corresponding flange
half ball joint e.
I connect by means of an
flange at the top, to this
situated at the base of the
The half ball joint d is constructed with a handle & fixed to a centre screw /
attached to the inside valve turning the gas on or off, the said half ball joint d
is attached to the half ball joint e by means of a crutch m bolted at each end to
the side of the half ball joint. In the centre of the crutch m I provide a
swell n which I drill and tap in order to receive a set screw o the end of which
presses against the centre of the cup situated at the back of the half ball
joint e. At each end of the half ball joint d is a male screw for the purpose
of connection by unions the gas tuber and blow pipe s.
is provided
with a series of ridges u for the purpose of being readily operated on by the
fingers.
The union
The inside cup a¹ is provided with a gas box and gas way holes these

page_text: said holes correspond with two holes f¹ in the half ball joint d. In the cup a¹
is also a blast way c¹ or box which conveys the blast through the blast hole d¹
into the blow pipe s.
In the tee g I provide a valve a for shutting off or regulating the blast from
or to the forge when using the apparatus for brazing, this I form by cutting
a slot in the tee and in the said tee I insert a slide w with a hole a. The
slide is formed with a head y in the front and a set screw z in the rear so
that in operating with the slide it is impossible to pull or push the same out
of the slot before described.
Tubes, are telescopic one being fixed to the tee piece g, and the other
carrying the flange i for the purpose of raising the blow pipe or working the
same circulary on its axis.
The object of my invention above described is to provide an apparatus to be
attached to a portable forge for brazing and manipulating the blast from the
blow pipe in any direction.
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 an apparatus for brazing attached to a portable forge, the combination
of the various parts constructed and fitted together in the manner fully described
in the above specification and illustrated in the accompanying drawing.
2. In an apparatus for brazing attached to a portable forge, the combination
of the half ball joint e joint d crutch m swell set screw o male screws handle k
centre screw and flange j substantially as herein described and according to
the accompanying drawing.
3. In an apparatus for brazing attached to a portable forge, the combination
of the slide whole heady set screw and slot to form the valve in the
tee g, substantially as herein described and according to the accompanying
drawing.
Dated this 23rd day of May 1898.
