Improvements in or connected with Hearths for Brazing and the like
purposes.
I, ROBERT JOSEPH JUDGE, of Westminster Works, Montgomery Street,
Birn ingham, in the county of Warwick, General Manager. do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in or connected with hearths for brazing
and the like purposes and is chiefly intended for use in the construction of kerbs,
and window frames or such other structures of considerable size and weight, where
the fire is required at various points; and its objet is to provide means whereby
the hearth proper may be movable to any desired part of the said structure; also
to provide in some cases improved means for the conveyance of the blast to the
movable hearth.
More
I construct a skeleton like framework or stand, and preferably of wrought
tubing, in which there are one or more (according to size required) series of
parallel bars or tubes upon which may rest the hearth proper. This hearth is
made having outstanding flanges or other suitable formations which may rest
upon the parallel tubes and thereby carry the hearth thereon. Hence the said
hearth may be moved to any desirable point along the said framework.
than one of such hearths may be used upon the same framework. The blast is
conveyed to the framework at any suitable point, generally emerging from below
the floor at about the centre of the framework, with its nozzle having one or more
braches to which may be connected flexible blast pipes, whose other ends are con-
nected to the tuyere of the hearth, thus permitting of a certain latitude of move-
ment of the hearth.
In some cases I further make the whole, or certain desirable parts of the frame-
work, of tubular construction and utilize it for the conveyance of the blast. In
such cases I connect the main blast supply at a suitable point to the framework,
and at various desirable points I place taps to which the flexible pipes (as before
mentioned) may be attached.
Thus by these means, a small fire may be concentrated upon any given spot of
the structure by a movement of the hearth, and little or no movement of the
structure, and a number of such hearths may be in concurrent operation.

I ROBERT JOSEPH JUDGE, of Westminster Works, Montgomery Street,
Birmingham, in the county of Warwick General Manager 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 or connected with hearths for brazing
and the like purposes, and is chiefly intended for use in the construction of kerbs,
and window frames, or such other structures of considerable size and weight,
where the fire is required at various points; and its object is to provide means
whereby the hearth proper may be movable to any desired part of the said
structure; also to provide in some cases improved means for the conveyance of
the blast to the movable hearth.
In order that this my invention may be more clearly understood I have
appended hereunto an illustrative drawing upon which are figures and numbers
of reference in which similar numbers refer throughout to the same thing or part.
Fig 1, is a side view; Fig 2, a pian view; and Fig 3, an end view of this my
invention.
Fig 4, illustrates a modification of this my invention.
I construct a skeleton like framework or stand 6, and preferably of wrought
tubing, in which there are one or more (according to size required) series of
parallel bars or tubes upon which may rest the hearths 7. These hearths are
made with outstanding flanges 8, or other suitable formations which may rest
upon the parallel tubes 6", and thereby carry the hearths thereon. Hence the
said hearths may be moved to any desirable point along the said framework.
One or more of such hearths may be used upon the same framework.
The blast is conveyed to the framework at any suitable peint, generally emerging
from below the floor at about the centre of the framework through a pipe 9, with
its nozzle 10, having one or more branches to which may be connected flexible
blast, pipes 11, 11, whose other ends 12, 12, are connected to the tuyere of the
hearth, thus permitting of a certain latitude of movement of the hearth.
In some cases I further make the whole, or certain desirable parts of the frame-
work, of tubular construction and utilize it for the conveyance of the blast. This
is clearly illustrated in Fig 4. In such cases I connect the main blast supply
pipe 9, at a suitable point to the framework, say into the upright pipe 6b, and at
varicus desirable points I place taps 14, to which the flexible pipes 11, (as before
mentioned) may be attached.
Thus by these means, a small fire may be concentrated upon any given spot of
the structure, (work under construction) by a movement of the hearth, and little
or no movement of the structure, and a number of such hearths may be in con-
current operation, as for instance, looking at the plan view in Fig 2, I may carry
an extension of a similar framework in any desirable direction as indicated by
dotted lines, which in the case of the framework being used to convey the blast,
such various frameworks would be suitably, connected direct or through each other
up to the main blast supply.
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:-
