COMPLETE SPECIFICATION.
Acetylene Gas Generating and Storing Apparatus.
I, EDVARD BJÖRNRUD, of No. 15, Bjerregaardsgade, Christiania, Norway,
Mechanic, 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 present invention relates to an acetylene gas generator constructed on the
principle of the automatic deposit of the carbide in the water.
The invention is illustrated in the accompanying drawings.
At the upper part of the generator there are a number of cylindrical or conical
chambers a, the number thereof corresponding to the size of the apparatus, which
chambers serve for the introduction of the carbide in fixed quantities, according.
to the size of the gasometer. These chambers a are closed gas-tight at the top
with a cover b pressed down by means of an eccentric lever c, and they are pro-
vided at the bottom with movable flaps which shut gastight abutting against
the thick outside ring e fastened to the bottom of the chamber a. The flaps d
are fastened to the arms f which are firmly joined to the axes g. These axes are
supported revolubly in bearings h h attached outside the chamber a.
The arms f
are provided with cylindrical weights which balance the carbide in the
chambers a.
The arm is connected with the vertical pipe which is closed at the bottom
in order to prevent the gas escaping during its production. The pipe or shaft k
which forms the axis of revolution.passes through the pipe m which latter is
firmly fixed to the plates. This outer pipe m only serves as a bearing for the
shaft k; the said shaft is revolved by means of a horizontal ratchet wheel device n.
The hollow shaft o of the ratchet wheel.device rotates the shaft k being connected
to the shaft by set screws . When the ratchet wheel revolves the arm j will
be revolved with it and will successively strike against the weights i and thus
open the flaps & through which the carbide drops.
The revolving of the ratchet wheel n is effected by the lowering of the bell A
by means of the chain p; the arm will then by striking against the weight i
with its oblique front edge, gradually open the Haps .and in this manner allow
the carbide to fall gradually into the water. The water is supplied from. the
gasometer through the cock q.
The arm is placed above the arm j and revolves therewith. If the bottom
of a chamber is opened by the arm j the arm will rest over the chamber and
prevent the opening of the chamber by the eccentric levere for the introduction
of carbide.
As the arm has also à similar oblique hinder surface, the weights i will aid
in the movement of the arm j.
During the rising of the gas bell, the ratchet wheel device is moved back again
by means of the weights through the chain which is fastened to a radial
arm revolving loosely around the top of the shaft k. Said radial arm. carries
a ratchet which works in the teeth of the ratchet wheel n or any other suit-
able mechanism may be used.

The cock serves for running off the waste lime sludge after the gas has been
generated. The grating prevents solid objects stopping up the outlet cock and
serves to divide up the carbide better during its decomposition.
The pipe a conveys the gas from the generator to the gasometer and the casing y
forms a water seal which prevents the gas escaping back to the generator. The
pipe in the gasometer is a safety pipe.
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 acetylene gas apparatus with carbide chambers arranged in the upper
part of the generator, which chambers are opened by a mechanism in operative
connection with the gas bell of the gasometer, the arrangement of flaps a form-
ing the bottoms of the carbide chambers, which flaps close the chambers under
the influence of counter-weights whereby an arm j revolved from the gasometer
strikes against these weights which raises the weight and consequently opens the
flaps, substantially as described.
2. In an apparatus substantially as set forth in Claim 1, a series of excentric
levers which close the covers of the chambers so arranged that the lever which
belongs to that carbide chamber the flap of which is open, is accompanied by
the arm and the opening of the carbide chamber prevented, substantially as
described with reference to the accompanying drawing.
