PROVISIONAL SPECIFICATION.
A Means of Collecting Hops or other Ingredients when Boiling or
in Circulation in a Copper or similar Vessel.
I, FRANCIS HENRY FORTESCUE of 01 West Smithfield London E.C.
Brewer's Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention consists of a boiling fountain or similar contrivance for preventing
over boiling in the copper and which has a sliding or fixed cage or strainer which
can be raised or lowered at will by means of slings.
This fountain, which is fixed inside the copper, causes a circulation of the liquid
containing the hops, which circulates up through the fountain, out at the top and
then descending to repeat the process passes through the raised strainer in which the
circulating hops are entrapped and from whence the wort escapes clear and free
from all hops, sediment or other foreign substances.
The strainer can be made cone shaped, cylindrical, square or in any other
suitable form, and with a separate loose or fixed plate or cup independant of the
strainer.
It will be seen that the great advantage of my invention lies in obviating the
necessity of running off the liquid into hop backs through a sieve or outside
strainer.
This invention may also be applied to all purposes where the straining or collecting
of foreign matter in boiling liquids is desired.

COMPLETE SPECIFICATION.
A Means of Collecting Hops or other Ingredients when Boiling or
in Circulation in a Copper or similar Vessel.
I, FRANCIS HENRY FORTESCUE of 61 West Smithfield, London, E.C. Brewer's
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 :-
This invention is designed to effect the automatio separation or collection of solid
matter from boiling liquids while boiling, thereby dispensing with the usual sub-
sequent straining or filtering operation.
The apparatus employed consists of the well known boiling fountain, composed of
one or more vertical or nearly vertical tubes, through which the heated liquor
ascends and overflows; and a suitable permeable or perforated receptacle, of
sufficient fineness of mesh to retain the solid matter which it is desired to
separate.
as it
My invention is especially adapted to the boiling of hops by brewers,"
prevents bolling over and dispenses with the necessity of running off the liquor
into hop-backs, that is through a sieve or outside strainer. It is however applicable
to all purposes in which the straining or collecting of solid matter or floating
substances in boiling liquids is necessary.
I will now describe the invention with reference to the boiling of hops, and as
illustrated by the accompanying drawings, in which

page_text: Fig. 1 shows one form of my apparatus furnished with a fountain having a straight
centre tube, and
Fig. 2 shows another form in which the upper end of the fountain tube is
ourved.
The fountain which consists of the hollow perforated base a, and the tube b, is
placed or fixed inside the boiler as shewn in Fig. 3, and when the liquor containing
the hops is heated, it passes upwards through the tube b, out at the top and falls
again into the boiler. In its descent it passes when desired, through the wire cage
or perforated receptacle c, c, or e, and the solid matter is thus detained previous
to drawing off the wort.
In the case of Fig. 1 the straining receptacle a, is placed around the tube b
and is arranged to slide vertically thereon. This strainer may have a perforated
bottom, or may have no bottom but be fitted to sit closely on the base a, or on a
horizontally fixed plate or cup attached to the tube b. It can be raised or lowered
by a sling or slings, or may if preferred be fixed in a suitable position, and the
bottom may be arranged to open and shut.
In Fig. 2, the straining receptacle. is suspended under the orifice of the bent
tube, before the wort is withdrawn.
In both cases the hops are entrapped and retained, while the wort escapes clear
and free from solid matter.
The strainer can be of any preferred size shape or strength, and can be fixed as
in c, Fig. 3, the tube b, or top of the tube, 6, revolving, so that the strainer is not
in use until the boiling is completed, when the tube being turned so as to pour
the liquor on it the strainer is brought into operation and caused to perform its
function.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :=
The combination with a boiling or circulating fountain fitted at top with a cap
or hood, or a fixed or revolving cowl or bent tube, of a loose or fixed cage or
strainer of any suitable size, shape or mesh,, the whole forming an automatic
separator or collector of solid or spent matter in boiling fluids during ebullition,
as herein described and set forth.
