JAMES CROSS and GEORGE ISAAC JAMES WELLS of Widnes in the County of
Lancaster Chemical Manufacturers IMPROVEMENTS IN APPARATUS FOR RAISING,
CIRCULATING AND DECANTING CERTAIN CORROSIVE AND OTHER LIQUORS
This Invention relates to a special construction of Injector and the combination
of it with a drop syphon The apparatus is especially adapted for raising
circulating and decanting Hydrochloric acid and its compounds and liquors containing
such.
The external casing of the injector which surrounds the nozzle and throat is
constructed of wood which has been previously saturated with boiled linseed oil in
the manner similar to that adopted for creosoting timber. This external portion
in some cases may be made of solid timber where the liquors upon which it is to
operate are at a temperature below 100° Fah but where they are in a boiling state
and at other temperatures the casing is preferably constructed of wood segments
securely jointed together with metallic or other bands-The nozzle and throat we
prefer constructing of earthenware but under certain circumstances they may bo
inade of other substances such as Stone Vulcanite India Rubber or Wood according
to the nature of the liquor upon which the apparatus is to operate in practice. The
injector may fixed independantly or be secured between various vessels for the
purpose of raising, circulating, decanting and emtying, the liquors from one vessel
to another.
An arrangement which may be adopted for these purposes is as follows:-A
horizontal tube of wood constructed preferably as above described for the casing of
the injector is secured against the sides or bottom of vessels containing the liquors
to be treated opposite holes which have previously been bored through their sides
or bottoms-Through these holes are threaded stout India Rubber tubes forming
drop syphons which project to a suitable distance inside the vessels The ends of
these tubes on the outsides of the vessels may be conveniently provided with

page_text: flanges by which the joints between the wood tubes and the outsides of the vessels
can be easily made tight at the same time securing the India Rubber drop syphons
in their places
Upon this horizontal tube is bolted or otherwise fastened the external casing of
the injector which stands vertically and which contains the throat-Immediately
under it the nozzle is fixed to which is attached the steam pipe for supplying the
injector This steam pipe is preferably lined with India Rubber or any substance
not acted upon by the liquor which is being operated upon. At the top of this
vertical casing or tube is fixed a distributing trough, launder, channel or pipe,
provided with a suitable number of orifices which may be opened or closed at
pleasure by small sluice doors paddles or valves. The liquor when raised by the
injector may be circulated from one vessel to another decanted or emptied by
suitably opening the valves of the distributor and adjusting the position of the
drop syphons
