Improvements in Means for Storing and Using Calcium Carbide or the ⚫
like for Acetylene and the like Gas Generating Apparatus.
I, EDWARD SAMUEL BOND, of Crown Works, Booth Street, Handsworth, Stafford-
shire, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in means for storing and using calcium
carbide or the like for acetylene and the like gas generating apparatus, and
primarily intended for use in connection with the generators of such apparatus
as now arranged for cycle and other similar service.
In such apparatus as at present used, the carbide of calcium is placed in a
perforated tube which is carried in the said apparatus. Amongst the objections
to this arrangement are the liability of dust like particles of the carbide to fall
and waste through the perforations; also the unpleasant odour consequent there-
from, and also the difficulty in cleaning such tubes after use, ready for re-charg-
ing. The primary object of this my invention is to obviate these difficulties and
to simplify the use, storage and carriage of this substance.
I prepare tubular cases, of metal or other suitable material having perforated
sides, and further provided with a removable cap at each end. The one end of
the tube is preferably contracted somewhat and taperwise, so that if desired such
end may be telescopically passed into the opposite end of a similar tube (when
the caps are removed) so as to form a tubular continuation. Within these tubes
I now place a lining of thin soluble paper, or other suitable material, and then
within such lining is placed the carbide, and the caps put on the ends. Hence
the carbide which is more or less fine in powder form will be perfectly safe from
waste. These tubes are made in various lengths affording selectively their various
times of burning capacity. By these means the carriage and storage of the carbide
is much improved as the cases may be thus made up and sold so cheaply as not to
demand re-charging, but may be thrown away, or even if such re-charging was
desired, the paper lining facilitates the cleaning process for a recharge.

ascertained in and by the following statement:
This invention relates to improvements in means for storing and using calcium
carbide or the like for acetylene and the like gas generating apparatus generally,
but primarily intended for use in connection with the generators of such apparatus
as now arranged for cycle and other similar service.
In such apparatus as at present used, the carbide of calcium is placed in a
perforated tube which is carried in the said apparatus. Amongst the objections
to this arrangement are the liability of dust like particles of the carbide to fall
and waste through the perforations; also the unpleasant odour consequent there-
from, and also the difficulty in cleaning such tubes after use, ready for re-charg-
ing. The primary object of this my invention is to obviate these difficulties and
to simplify the use, storage and carriage of this substance.
In order to explain more clearly this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, in
which:-
Fig. 1, shows in elevation, this my improved carbide holder.
Fig. 2, is a sectional view of the carbide holder on line A-B, Fig. 1.
I prepare a tubular case 4, of metal or other suitable material having perfora-
tions 5, in its side, and further provided with a removable cap 6, 6", at each end.
The one end 7, of the tube is preferably contracted somewhat and taperwise, so
that if desired such end may be telescopically passed into the opposite end 8 (when
the caps are removed) so as to form a tubular continuation. Within these tubes I
now place a lining 9, of thin soluble paper, or other suitable material, and then
within such lining is placed the carbide (not shown) and the caps put on the ends.
Hence the carbide which is more or less fine in powder form, will be perfectly
safe from waste, when used in tubes perforated in this manner... These tubes
are made in various lengths affording selectively their various times of burning
capacity. By these means the carriage and storage of the carbide is much
improved as the cases may be thus made up and sold so cheaply as not to
demand re-charging, but may be thrown away, or even if such re-charging was
desired, the paper lining facilitates the cleaning process for a re-charge, inasmuch
as the lining prevents considerably if not entirely the adhesion of the products
of decomposition to the sides of the tube, so that the latter may be readily cleaned
for re-charging.
I am aware that absorbent linings have been used in carbide cartridges, but as
their name indicates have been used to control the supply of water to the carbide,
and not to prevent waste of (fine) carbide during storage or transit as no side
perforations have been used with such linings.
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:
1. The combination of a calcium carbide holder 4, having perforations 5, in
its sides, and the lining 9, as set forth and shown and for the purposes specified.
