Improvements in Condensers and Towers for the Condensation of
Acid and Corrosive Gases.
I DOUGLAS HERMAN of West Park St. Helens in the county of Lancaster Chemical
Engineer do hereby declare the nature of this invention to be as follows :-
:-
The object is to provide for condensing acid and corrosive gases, apparatus having
the following advantages; efficiency, durability, resistance to the action of the gases,
with facility for erection and renewal in whole or part.
The invention consists essentially in constructing the condensers and towers of a
series of glass pipes or tubes, carried or borne by bearers, each of the said pipes or
tubes having at one end an external flange or projection, and at the other an internal
flange or projection, the whole being placed if desired in a suitable casing.
A further improvement consists in making the ends of the pipes or tubes having
internal flanges or projections, of less diameter than the ends having external
flanges or projections, and fitting the ends of the said pipes or tubes one within the
other.
Another improvement consists in supporting all or some of the said tubes,
constituting a condenser or tower, by bearers placed outside the glass pipes or tubes.
Coke or other suitable material offering a large surface for the condensation of the
gases is placed and supported in each of the said pipes or tubes.
Air, water, or other cooling or condensing fluid is employed in any usual manner.
Dated this 14th day of December 1887.

I DOUGLAS HERMAN of West Park St. Helens in the county of Lancaster Chemical
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 :-

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a view part in elevation and part in vertical section and fig. 2 a plan of a
condenser tower under my invention. a are glass pipes formed at the top with
external flanges and at the bottom with internal flanges & the lower end of one tube
fits within the upper end of the tube beneath. d are glass grids resting on the internal
flanges c, the interior of the tubes is filled with coke or other suitable material
preferably bits of waste or broken glass. e are cross-bearers of wood metal or suitable
inaterial built into or carried by the walls of a tower. fare curved blocks resting on
the crossbearers and furnished at their upper ends with strips of indiarubber or
resilient material which fits under the external flanges of the tubes and so sustains
them in position.
It will be evident that the shape and disposition of the parts constituting my
improved condenser tower may be varied without departing from my invention but
I have found the construction shewn to answer well in practice.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is.
First. Condensers and towers consisting of a series of glass pipes or tubes having
flanges and borne by bearers substantially as herein set forth.
Second. Constructing condensers of a series of glass pipes or tubes having external
and internal flanges and fitting one within the other substantially as set forth.
Third. The combination of glass pipes or tubes with bearers and grids substantially
in the manner and for the purpose set forth.
