of York, Spinner, for an Invention of "IMPROVEMENTS IN APPARATUS
PROVISIONAL SPECIFICATION left by the said Robert Sutcliffe at the
Office of the Commissioners of Patents on the 2nd December 1880.
ROBERT SUTCLIFFE, of Castle Mills, Idle, in the County of York, Spinner.
"IMPROVEMENTS IN APPARATUS EMPLOYED FOR CLEANING THE FLUES OF STEAM
BOILERS."
This Invention relates to further improvements or apparatus for purpose
aforesaid, for which Letters Patent, No. 828, A.D. 1874, were granted to me, the
Invention aforesaid baving proved of great public utility and commercial value.
It is found however that hot slag cinders and fuel occasionally forced over the
bridge and upon the perforated steam pipe, described in the Specification of the
Patent aforesaid, and in time burn out and destroy the furnace end of the said
pipe.
My improvements consist in the use of a cast iron cover for the steam pipes,
which I construct of two incline surfaces, or in the form of a dome or arc, the
covering being provided with feet or rests, and the upper part of the cover is so
constructed with openings, and by means of the feet referred to, as not to impede
the full blast or force of the steam used or discharged through the perforated pipe
for the purpose of clearing the flues.

the said Robert Sutcliffe in the Great Seal Patent Office on the 1st June
1881.
ROBERT SUTCLIFFE, of Castle Mills, Idle, in the County of York, Spinner.
"IMPROVEMENTS IN APPARATUS EMPLOYED FOR CLEANING THE FLUES OF STEAM
BOILERS."
This Invention relates to further improvements or apparatus for purpose
aforesaid, for which Letters Patent No. 828, A.D. 1874, were granted to me, the
Invention aforesaid having proved of great public utility and commercial value.
It is found however that hot slag cinders and fire occasionally forced over the
bridge, and upon the perforated steam pipe described in the Specification of the
Patent aforesaid in time burn out and destroy the furnace end of the said pipe.
My improvements consist in the use of a cast iron cover or fire clay cover for
the steam pipes, which I construct of two incline surfaces, or in the form of a
dome or arc, the covering being provided with feet or rests, and the sides of the
cover are so constructed with openings, and by means of the feet referred to, as not
to impede the full blast or force of the steam used or discharged through the
perforated pipe for the purpose of cleaning the flues.
Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the same may be fully understood
I have hereunto annexed a Sheet Drawings illustrative thereof; in which is
shewn a longitudinal section of a boiler having the steam pipe for cleaning the
flues protected by cast iron or fire clay cover.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a longitudinal section of a steam boiler having my improvements
applied thereto; Figs. 2 is a longitudinal elevation of the cover, and at Figs. 3 and 4
are cross sections of two forms of cover.
A, is the steam boiler; B, a steam pipe carried along the bottom of the flue C¹
near the bridge E. The said pipe being covered and shielded by the iron or fire
clay cover F, the latter having feet or stands G, so as to leave ample space or
openings H, H, for the free and effective action of the blast of steam. The said
cover F may be in the form of an arc, angular inverted ^ or other form, so long
as it is adapted to protect the steam pipe from the action of the heat and afford
free egress for the blast of steam.
Having thus fully described the nature and object of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that I claim as my
Invention,―
The application and use of the cover F in combination with the steam pipe B as
and for the purpose aforesaid.
In witness whereof, I, the said Robert Sutcliffe, have hereunto annexed my
hand and seal; this Twenty-seventh day of May, in year of our Lord
One thousand eight hundred and eighty one:
