I, WILLIAM PHILLIPS THOMPSON, F.C.., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 6, 1ord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, 118 New Street, Birmingham in the County of Warwick
and 322 High Holborn in the County of Middlesex, Civil Engineer, 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 object of this invention is to provide an apparatus for developing illuminating
gas from carbide of calcium or similar carbides, the said apparatus being so constructed
and arranged, that the carbide may be charged into the apparatus without the least
interruption of the operation and without any material loss of gas. The carbide
charge is located within or in such connection with the rising and descending gas-bell,
that by the descent of said bell, i.e. when the stock of gas contained in the bell is
reduced, the carbide will be immersed in the water, whilst when the bell rises, i.e. when
the stock of gas increases, the carbide will be lifted out of the water, thereby stopping
or reducing the further development of gas. The generation of gas, accordingly, is
automatically controlled by the rising and descending hell, or, in other words, by the
rate of delivery going on.
In the accompanying drawing, which forms part of this specification, the improved
apparatus embodying the invention is represented in sectional elevation. A, is the
bell of usual kind, arranged to move up and down in a water-tank, B, guided by little
wheels. To the top of said bell, inside the same, a container C is secured, the lower
part of which is preferably funnel-shaped. A perforated plate, or grate of any
kind, D, is provided within said container, C, which grate serves to receive the charge
of carbide, from which the gas is to be developed. Below the said container, C, a
tank, H, of similar shape to said container but of larger size, is placed within the
tank B. The said tank, H, contains water, as well as the tank, B, but the two tanks B
and H do not communicate with each other. The water contained in the tank B may
contain salt, as usually employed in apparatus for generating acetylene gas, while the
water contained in the tank H is free of such addition of salt. The said tank, H,
communicates by a pipe M with an outside reservoir, L, which serves to fill up the
quantity of water contained in the tank, H, and the level of water in the said tank
may thus be easily controlled by adjusting the level existing within the reservoir, L,
the cover of which may be readily removed.
It will be readily understood, that as the bell A descends, as indicated by dotted
lines, the funnel or container C will be immersed in the water contained in tank, H,
and the water will reach the carbide through the perforated plate or grate D. Gas
being developed by such access of water to the carbide, the bell A will rise again and
the carbide will be lifted out of the water, the production of gas will cease or be
reduced, until the bell descends again. The play will be repeated until the charge of
carbide is exhausted. The slime of the carbide will fall through the perforations or
grating of the support, D), and sink down through the funnel H, into a receptacle, K,
placed below the funnel, H, the said receptacle, K, being connected to the funnel, H,
