PROVISIONAL SPECIFICATION.
Improved Apparatus for Straining or Filtering Liquids.
I EDWIN LOWE of Wilton Arms Denton in the County of Lancaster, Inn
Keeper, do hereby declare the nature of this invention to be as follows :—
This invention relates to improvements to be applied to funnels whereby they
can conveniently be made to serve the purpose of filtering or straining liquids
whilst they are being poured through them into a bottle or other vessel, and the
filtering medium can readily be renewed.
The invention consists principally in making the funnel in two parts, namely, the
liquid holder, and the flow tube, which can be readily detached and connected
together again by screwing or otherwise, means being provided for the introduction
between the two of a piece, or pieces, of felt, gauze, cloth or similar porous material
in such a way that the liquid in passing from the holder into the flow the must of
necessity pass through the felt other filtering medium.
For this purpose I prefer to make the lower end of the holder with a short boss
screwed on the outside, and I make the flow tube with a corresponding 'flange at
the top, and I provide a nut screwed upon the inside whereby the two can be
readily connected together in the manner of an ordinary union joint. A space is
left between the two for the insertion of a piece or pieces of felt, gauze, or other
porous material which forms the filtering medium which may be more or less porous
according to the nature of the liquid to be strained or filtered and which can be at
any time renewed or replaced by unscrewing the connecting nut.
I do not desire to confine my invention to the above described method of uniting
the two parts of the funnel, as other methods may be devised which would answer
the same purpose of detaching and re-uniting the two parts, so as to secure the
filtering medium between them.

COMPLETE SPECIFICATION.
Improved Apparatus for Straining or Filtering Liquids.
I EDWIN LOWE of Wilton Arms Denton, in the County of Lancaster Inn-
keeper, 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 relates to improvements to be applied to funnels whereby they
can conveniently be made to serve the purpose of filtering or straining liquids
whilst they are being poured through them into a bottle or other vessel and the
filtering medium can readily be renewed.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the
drawings annexed and the following explanation thereof.
Fig. 1 is an elevation of my improved filtering funnel complete and Fig. 2 is a
vertical section of the parts detached.
The invention consists principally in making the funnel in two parts, namely the
liquid holder a and the flow tube & which can be readily detached and connected
together again by screwing or otherwise, means being provided for the introduction
between the two of a circular piece, or pieces, of felt, gauze, cloth or similar

page_text: porous material c in such a way that the liquid in passing from the holder a into the
flow tube must of necessity pass through the felt or other filtering medium e.
For this purpose I prefer to make the lower end of the holder a with a short
boss screwed on the outside and I make the flow tube with a corresponding
flange e at the top, and I provide a nut screwed upon the inside whereby the two
can be readily connected together in the manner of an ordinary union joint as shown
at Fig. 1. A space is left between the two for the insertion of a circular piece or
pieces of perforated metal, felt, gauze, or other porons material e which forms the
filtering medium which may be more or less porous according to the nature of the
liquid to be strained or filtered; the edges of which are compressed firmly between
the bottom of the screwed boss d and the top of the flange e, and which can be at
any time renewed or replaced by unscrewing the connecting nut f
The straining or filtering disc being readily removable can also be thoroughly
cleansed on both sides before being replaced.
I do not desire to confine my invention to the above described method of uniting
the two parts of the funnel, as other methods may be devised which would answer
the same purpose of detaching and re-uniting the two parts, so as to secure the
filtering medium between them.
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
A filtering funnel made in two detachable and re-unitable parts izt., a liquid
holder and a flow tube, with means for introducing and securing between the two a
perforated strainer or a piece of felt or other filtering medium substantially as
herein before described and illustrated by the drawings annexed.
