PROVISIONAL SPECIFICATION.
A Combined Water Filter and Pump.
We, JAMES DIXON and JOHN SKIRROW, of 21 York Place, Leeds, in the
County of York, Water Filter Manufacturers, do hereby declare the nature of
this invention to be as follows:-
Our invention has reference to pumps, especially that class employed in pumping
water for drinking and domestic purposes, and it consists in combining a filtering
instrument with a pump. We prefer to screw or otherwise fasten a filter of
suitable construction to the outlet end of the pump, so that all water passing there-
through will be filtered and rendered fit for domestic use simultaneously with being
drawn ;
but we may also combine filters with pumps used for manufacturing
purposes, so as to filter the feed water of steam boilers issuing from canals, rivers,
and other like places. By combining water filters with pumps they will be found
of great service in agricultural districts, also for military expeditions, and other
uses.

COMPLETE SPECIFICATION.
A Combined Water Filter and Pump.
We, JAMES DIXON and JOHN SKIRROW, of 21 York Place, Leeds, in the
County of York, Water Filter Manufacturers, 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 :-
Our invention has reference to pumps, especially that class employed in pumping
water for drinking and domestic purposes, and it consists in combining a filtering
instrument with a pump. We prefer to screw or otherwise fasten a filter of
suitable construction to the outlet end of the pump, so that all water passing there-
through will be filtered and rendered fit for domestic use simultaneously with being
drawn; but we may also combine filters with pumps used for manufacturing
purposes, so as to filter the feed water of steam boilers issuing from canals, rivers,
and other like places.
In order that our invention may be better understood, we will now refer to the
annexed drawings, and although we do not limit ourselves to the adaptation of any
particular description of filter to a pump, we prefer to use the one illustrated in the
This
drawings, of which Fig. 1 is elevation and Fig. 2 vertical section of same.
filter comprises a case or shell A made of any suitable material; the casing being

enclosed by covers B and C, which are screwed onto the said case.
of the casing A is filled with ground quartz D, which is not absorbent like felt,
sponge, and other porous material, and therefore will not become foul if properly
attended to. In the centre of the case or shell we employ a distributing disc E,
shewn in Fig. 3, suspended or placed in such a way within the case as to divert the
flow of water from a straight course through the filter, thereby breaking the said
water into a spray and throwing it into all parts of the filtering substances, whereby
the filtering power of the material is increased. The distributing disc E is provided
with arms F, which rest upon the metal rings G, such rings supporting wire screens
or strainers H provided at each end of the case or shell. The covers B and C at
each end of the shell have screwed openings K whereby the filter can more easily

page_text: be attached to the pump shewn in Fig. 4 which represents a well known form of
portable pump.
If the ground quartz becomes in any way foul by continuous use, it may be
easily cleaned by unscrewing the filter off the pump and applying it in the reverse
way so that the water rushing through in the opposite direction will remove the
impurities.
By combining a water filter with a pump as illustrated in Fig. 4 it will be found
to be of great service in agricultural districts, and also for military expeditions and
other like uses.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combining of a filter with a water pump for purposes and in manner
substantially as herein shewn and described.
