PROVISIONAL SPECIFICATION.
Improved Electrical Furnace.
EDWIN BURBAGE PHILLIPS, of Avondale Villas, Uppingham Road, Leicester,
and WALTER HENRY BRAY, of 1, The Avenue, Eastville, Bristol, do hereby
declare the nature of this invention to be as follows:
Applicable to furnaces of the horizontal and open hearth type. Our first im-
provement relates to a convenient means of carrying the "electrodes" which we
do by having a pair of brackets to each being attached two or more wheels or
pinions which run upon suitable tracks on the two top edges of the furnace, a
handle being fixed at the side for the purpose of adjusting, the said brackets
are made to fit on the opposite sides of electrode and having a projection
running longitudinally which fits into corresponding grooves in the said electrode,
which is then clasped tightly by means of a screw which is placed in a suitable
position between the said brackets with a handle attached. By the use of
these slots in electrode and the projections on brackets we are enabled to get
a speedy adjustment and also avoid waste in electrodes. Our second improve-
ment relates to that part of the furnace immediately below and between the
two electrodes and upon which the material is being treated. This portion we
arrange to be gradually lowered by means of a screw or rack and pinion which
is placed on the under side of the furnace. By this means we are able to
increase the quantity of calcium carbide produced and at the same time economise
in the cost of working by utilising the waste heat from the fused material.

We, EDWIN BURBAGE PHILLIPS, of Avondale Villas, Uppingham Road, Leicester,
WALTER HENRY BRAY, 1, The Avenue, Eastville, Bristol, 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: –

Applicable to furnaces of the horizontal and open hearth type. Our first im-
provement relates to a convenient means of carrying the electrodes which we
doby having a pair of brackets, to each being attached two or more wheels or
pinions which run upon suitable tracks on the two top edges of the furnace, a
handle being fixed at the side for the purpose of adjusting, the said brackets
are made to fit on the opposite sides of electrode and having a projection
running longitudinally which fits into corresponding grooves in the said electrode,
which is then clasped tightly by means of a screw which is placed in a suitable
position between the said brackets with a handle attached. By the use of
these slots in electrode and the projections on brackets we are enabled to get
a speedy adjustment and also avoid waste in electrodes. Our second improve-
ments relates to that part of the furnace immediately below and between the

arrange to be gradually lowered by means of a screw or rack and pinion which
is placed on the under side of the furnace. By this means we are able to
increase the quantity of calcium carbide produced and at the same time economise
in the cost of working by utilising the waste heat from the fused material.
For purposes of illustration we will now refer to the annexed drawings in
which:-
Figure 1, is a sectional end elevation shewing our invention.
Figure 2, sectional side elevation of same.
Figure 3, plan view of same.
Figure 4, view of our invention in position shewing the apertures in the floor
of a building for the dropping of the produced carbide of calcium.
Referring to Figures 1, 2 & 3, d are the electrodes which are clipped by means
of the travelling brackets g when required, these brackets are caused to travel in
the required direction through the medium of the hand wheel and toothed
wheels b which engage upon the rack c. s are strengthening brackets for use
with brick work. By this arrangement it will be seen that when the hand
wheel is rotated, the carbons may be gripped between the travelling brackets g
and by the rotation of the hand wheels a, may be caused to approach one another.
For the purpose of saving time, independent adjustment may if desired take place
by releasing the clipping action of the brackets g from the electrodes d when
they may be moved in the required direction, the ends of the brackets g travelling
in the electrodes d.
o is a block which may be raised or lowered through the medium of the
screw rod k pivotally connected thereto at p, this screw rod & being operated
through the medium of the wheel m, and the wheel n connected together by
the band ', said wheel n being operated by the rod and hand wheel h, for
the purpose of lowering the block as the carbide is formed.
e represents any
convenient means of connecting the electrodes to the source of current. In
Figure 4, the screw rod b' is pivotally carried by the bracket 2 and may be
rotated when required so as to allow the block or carbide c to fall into the position
shewn after its formation.
Although for purposes of illustration we have shewn certain details of con-
struction, it will be understood from our specification that these details might
be varied without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. An improved electrical furnace for the purpose of producing a carbide of
calcium, substantially as described and illustrated herein.
2. In electrical furnaces for the production of carbide of calcium, electrodes
adapted to be operated through the medium of clipping brackets, said brackets
being moved or adjusted through the medium of rack or pinion wheels or such
suitable and well known mechanical arrangement, when desired, said electrodes
also being free to be moved independently of the bracket, when released there-
from, said electrodes being connected to a source of current and the carbide
formed between said electrodes, being lowered as required through the medium
of the sliding block or support operated by means of a screw rod or other suitable
arrangement for the purpose of enabling the carbide to be withdrawn from the
electrodes as required, substantially as described and illustrated herein.
