Improvements in Apparatus for Supplying Blast to Forges.
I, GUSTAV ELSÄSSER of 124 Charlottenstrasse, Stuttgart, in the German
Empire, Master Smith, 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 :—
The subject of this invention is a contrivance for supplying (and regulating)
air blast to forges, possessing advantages over those now in use inasmuch as it
will prevent overforcing and weakening of the blast (supplied from below),
besides completely avoiding any fouling of the air-passage, as the ashes fall
directly into a special receptacle provided with a sliding door by means of which
they can be cleared out.
The accompanying drawings will help to explain the contrivance.
Fig. 1 shows a sectional elevation.
Fig. 2 shows a plan of the same.
The contrivance consists essentially of a chamber a into which is inserted the
short butt-pipe b in a direction slightly inclined from the vertical, forming a
continuation of the blast pipe c. The upper part of the chamber a is fitted with
a removable lid or centrepiece d, having a raised outlet in its centre, around and
over which is placed the retaining dish e, also removable, which serves to hold
the fuel and is so formed as to allow free manipulation of the heaviest work.
The lower end of the chamber a is furnished with a sliding door f which provides
for the cleaning out of ashes or bits of dross which may fall through the outlet d
into the chamber a, and may be furnished with a handle f¹, the length of which
will depend upon local requirements.
For the regulation of the blast a valve y is provided which serves at the same
time to knock off the slag which may have formed around the work, for which
purpose it is connected with a lever h which acts through the slot g¹ of the valve
rod gwhile its end is pivoted at some fixed point which is not shown in the
drawing.
The length of the lever h, like that of the handle f¹ of the slide f, depends upon
local requirements.
It may be further observed that the contrivance can be adapted for left and
right fires.
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 :-
1. In apparatus for supplying blast to forges, the combination of a chamber
with a short butt pipe for admitting the blast inserted at a slight inclination from
the vertical, for the purpose above mentioned.
2. In apparatus for supplying blast to forges, the combination of a chamber
with a blast pipe or jet conveying the wind or blast iuto said chamber at an angle
with the vertical and a means of regulating the blast, substantially as described.
3. In apparatus for supplying blast to forges, the combination of a chamber a

-slide substantially as described.
