A New or Improved Method or Means of Cleaning the Outside
Surfaces of Stone or Brick Buildings.
We, HENRY SLADE CHILDE, Civil Engineer, of Homegarth, Wakefield, and
ARTHUR HUTCHINSON SMITH, Mechanical Engineer, c/o Henry Smith, of St.
Johns Square, Wakefield, both in the County of Yorkshire, do hereby declare
the nature of our invention to be as follows:-
This invention relates to a new or improved method or means of cleaning the
outside surface of stone or brick buildings and has for its object to obviate the
tedious and costly means heretofore adopted for this purpose and to dispense to a
great extent with the necessity of repainting such surfaces.
According to our invention I employ the principal of the sand-blast in cleaning
stone or brick walls or other surfaces. The blast which may be produced by steam
or compressed air should be regulated according to circumstances, the force being
such that only a thin layer of the outer surface of the wall should be removed in
order that a fresh or renovated surface may be exposed.
The apparatus employed may be of the ordinary sand-blast jet construction
connected by a long flexible tube with a steam generator or with a rotary fan or
other suitable air compressing or forcing apparatus.
In using the apparatus it may be suspended from a carriage travelling on a
framing fixed to the upper part of the building so as to travel over the whole
surface thereof, or it may be carried in any other suitable manner and directed
either by hand or by suitable connections from below.

A New or Improved Method or Means of Cleaning the Outside
Surfaces of Stone or Brick Buildings.
We, HENRY SLADE CHILDE, Civil Engineer, of Homegarth, Wakefield, and
ARTHUR HUTCHINSON SMITH, Gentleman, c/o Henry Smith, of St. Johns Square,
Wakefield, both in the County of Yorkshire, 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 a new or improved method or means of cleaning the
outside surfaces of stone or brick buildings and has for its object to obviate the

page_text: tedious and costly methods hitherto in use for this purpose and to dispense to a
great extent with the necessity for re-painting such surfaces.
In carrying out our invention we employ the principle of the sand-blast applied
to the outside surfaces of stone or brick walls or buildings whereby the same are
quickly and thoroughly cleaned.
The said sand-blast which may be produced by steam or compressed air should
be regulated according to circumstances the force being such that only a thin layer
of the outer surface of the wall should be removed in order that a fresh or
renovated surface may be exposed.

The apparatus employed may be of the ordinary sand-blast jet construction con-
nected by a long india-rubber or other flexible tube with a steam generator or
with a rotary fan or other suitable air compressing or forcing apparatus.
When applying the apparatus for cleaning the outer walls or surfaces of a
building it is preferably suspended from a truck or carriage travelling on a fram-
ing fixed to the upper part of the building.
By this means the said apparatus may be carried both horizontally and verti
cally over the whole surface of the building to perform the work required.
Or the apparatus may be carried in any other suitable manner and be directed
and operated either by hand or by a suitable connections and mechanism from
below.
The action of the sand-blast upon the surfaces of walls or buildings effectually
cleanses the same by readily removing all stains and incrustations from the said
surfaces and reducing them to an even and finished appearance.
It also permits a thin coat of paint to be at once applied thus saving consider-
able time and labour in comparison with the methods hitherto adopted, or the coat
of paint may be dispensed with the sand-blast itself, by removing a thin layer of
the outer surface producing a sufficiently clean and finished appearance.
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) In an improved method or means for cleaning the outside surfaces of stone
or brick buildings the application of a sand-blast to the said surfaces for creating
a smooth and finished appearance to the same substantially as described.
(2) In apparatus for cleaning the outer surfaces of stone or brick buildings the
application of sand-blast mechanism in connection with a steam generator or a
rotary fan or other suitable air compression, or forcing apparatus and operated by
hand or by any suitable mechanism substantially as described.
