windows, Causeways, Yards, and for other Purposes.
We DAVID BUTTERFIELD, Ironfounder of Park Street Keighley Yorkshire and
GUSTAVUS ADOLPHUS JOHN SCHOTT Manufacturer of Richmond road Bradford
Yorkshire do hereby declare the nature of our invention for IMPROVEMENTS IN
IMPLEMENTS USED FOR WASHING CARRIAGES WINDOWS CAUSEWAYS YARDS AND FOR
OTHER PURPOSES to be as follows:
This Invention relates firstly to brushes mops and other similar implements used
for washing carriages windows causeways yards and for other purposes and this
portion of our improvements consists in fitting the said implements with a conduit
ending in a rose perforated tube or other suitable arrangement placed above or in the
central portion of the brush mop or other implement. The opposite end of the conduit
is provided with a tap and so arranged that flexible hose may be connected thereto
supplying water under pressure from a tap or reservoir which is forced out in one or
more jets through the Outflow aperture or apertures before mentioned whilst the
implement is being applied to its purpose at the same time.
The tap at the end of the conduit where the water enters serves to admit regulato
or cut off the supply of water as required.
By these means much water and time are saved and in order to illustrate more
clearly the convenience and economy resulting from the use of our improved
implements we will as an example institute a comparison with the mode at present
much in use for washing railway carriages.
The men now frequently perform this work by means of long-handled brushes or
mops and pails of water. They dip the brush or mop into the water and then apply
it to the carriage; the greater portion of the water never comes in contact with the
carriage but is lost between it and the pail whilst a great portion of the time and
labour of the men is wasted and their work of scrubbing constantly interrupted
owing to their having to replenish their brush with water.
By using a brush or mop fitted with our improvements as described the water
comes in contact with the carriage directly copiously and continuously at the very

page_text: same time that the scrubbing process is being carried on which need not be interrupted
until the operation is finished and a considerable saving is thereby effected.
The second series of our improvements relates to portable pails tanks or vessels
from which the water may be supplied to our improved implements as before
described under sufficient pressure for the purpose when the ordinary means before
mentioned of obtaining water at the necessary pressure are not available. Vessels of
various constructions may be used for this purpose and they may be of small size so
as to be portable by hand or of larger size mounted on wheels. They may consist of
an open pail or tank in which a suitable pump is mounted which may be worked by
hand or foot or other power.
Another suitable apparatus consists of a closed tank into which water is forced by
a pump or other means thereby compressing the air contained in the tank and from
which the water is afterwards ejected through an outflow aperture provided with a
tap and arranged at or near the bottom of the tank when such tap is opened, owing to
the pressure previously put upon the contents of the tank.
A third plan is to use a cylindrical vessel filled with water which is forced out
through an aperture at or near the bottom of such vessel by a weighted piston fitted
in the said cylinder and descending therein by its own weight.
Improvements in Implements Used for Washing Carriages,
Windows, Causeways, Yards, and for other Purposes.
We, DAVID BUTTERFIELD, Ironfounder, of Park Street Keighley and GUSTAVUS
ADOLPHUS JOHN SCHOTT, Manufacturer, of Richmond road, Bradford, both in the
County of York 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 firstly to brushes, mops and other similar implements used
for washing carriages, windows, cuuseways, yards and for other purposes and this
portion of our improvements is illustrated in Figs. 1 and 3 accompanying, and
consists in fitting the said implements, which in this instance are represented by a
brush and stale, such as are commonly used for washing railway carriages, shop
windows and for other purposes, with a conduit F ending in a tube G, which is bent

page_text: round the upper portion of the brush head E and provided with a number of
perforations through which the water spurts out in jets, or the conduit F may be
fitted with a rose or other suitable arrangement placed above or in the central portion
of the brush, mop or other implement. The lip H serves to intercept and throw off
any water which would otherwise be running down along the stale, when the brush
is held aloft.
The opposite end of the conduit F is provided with a tap D and so arranged, that
flexible hose C may be connected thereto supplying water under pressure from a tap
or reservoir, which is forced out in one or more jets through the outflow aperture or
apertures before mentioned, whilst the implement is being applied to its purpose at
the same time. The tap D serves to admit, regulate or cut off the supply of liquid
as required.
By these means much water and time are saved.
The second series of our improvements relates to portable pails, tanks or vessels
from which the water may be supplied to our improved implements as before described
under sufficient pressure for the purpose, when the ordinary means before mentioned
of obtaining water under the necessary pressure are not available. Vessels of various
constructions may be used for this purpose and they may be of small size, so as to be
portable by hand, or of larger size mounted on wheels. They may consist of an open
pail or tank, in which a suitable force pump is mounted, which may be worked by
hand or foot or other power, the hose C being connected to the outflow of such pump.
Another suitable apparatus consists of a hermetically closed tank A Figs. 2 and 3
into which water is forced from a water tap, by a pump or other means, thereby
compressing the air contained in the tank, and from which the water is afterwards
more or less violently ejected through an outflow aperture provided with a tap B and
arranged at or near the bottom of the tank A, when such tap B is opened, in pro-
portion to the pressure previously put upon the contents of the tank A. This pressure
depends upon the extent, to which the tank A is filled with liquid and must of course
be proportionate to the structural strength of such tank. We find a pressure of
about 30 lbs. per square inch or three atmospheres sufficient for ordinary use, to attain
which the tank A would have to be filled to two thirds of its capacity with liquid.
All the liquid would be driven out of the tank A by the expansion of the compressed
air above it, but a portion of the liquid would not be ejected with sufficient force to
cause it to spurt out from the tube G, particularly if the brush was held aloft.
To remedy this defect we provide the vessel H Fig. 2 as an intermediary in the
act of filling the tank A. The process of filling is then as follows, as illustrated in
Fig. 2:
At the commencement the vessels II (which we will suppose to be of half the
capacity of the vessel A) and A are empty, that is to say filled with atmospheric air
merely, the cock or tap L is closed whilst B is open. Then let water under pressure
enter through a tube or hose M, it will fall to the bottom of vessel H and rising therein
will press the air contained in H through the connecting tube or hose Ninto the
vessel A, which thus will contain half as much again air as it did originally, that is to
say be under a pressure of 14 atmospheres.
When the vessel H is filled with water, the latter follows the air into the vessel A
and mounts up therein. When it has half filled the vessel A the desired pressure of
atmospheres is reached and the filling process stopped, the cock B is closed, the
tube N disconnected therefrom and the cock L of vessel H is opened, whereby the
water contained in H is discharged, whilst air enters through the tube N and
the vessel H is thus ready for a repetition of the process.
The vessel H may be fitted with a safety valve I, set to blow off at any given
pressure, and a pressure gauge K of any convenient constructions, as indicated in
Fig. 2, which of course act also for the vessel A, whilst the same is being filled
through the vessel H.
On opening the tap B of vessel A, to which the tube Chas previously been con-
nected, the whole of the water contained therein will now be ejected with sufficient
force and, if directed upwards, to a sufficient height for the purpose.

page_text: In the side of the vessel A at the level to which the same is to be filled, we insert
an indicator or gauge 0 of a novel construction. It consists of a circular glass disc
hermetically set in a brass frame provided with screw thread, which is screwed into or
upon a corresponding circular rin fixed in the vessel A and which is also provided
with a screwthread and surrounds an aperture in the side of the vessel A, which
admits the water to the said glass disc; the appearance of the water behind the said
glass disc indicates, that the vessel A has been filled to the required height. A highly
coloured cork of suitable dimensions or other float may be placed behind the glass
disc and by rising with the water will render the appearance of the water behind the
dise more conspicuous. By unscrewing the glass disc and frame the aperture can be
utilised in washing out the tank A.
A vertical tube may be inserted in the centre of the top of the vessel A and reach
to nearly the bottom thereof.
Such vertical tube must be fitted with a tap at its upper end for opening and
closing the same as required and the hose C of the brush may be connected thereto.
We would have it understood however, that we do not confine ourselves to tho
precise details of construction as herein before specified, as such details admit of
modification according to requirements.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare, that what we claim is :
1. Fitting a brush or similar implement with a conduit F, tap D, perforated tube or
rose G, lip H, for use in combination with a flexible tube bringing liquid under
pressure, substantially in the manner and for the purposes herein before specified
and shown.
2. The hermetically closed tank A, aperture and tap B, indicator O, with or
without a vertical tube inserted in the top and descending to near the bottom of the
tank A, combined and arranged substantially in the manner and for the purposes
