PROVISIONAL SPECIFICATION left by the said David Thomas and Joseph
Thomas Robson at the Office of the Commissioners of Patents on the 4th April

DAVID THOMAS, of Upper Tulse Hill, Roupell Park, in the County of Surrey, and
JOSEPH THOMAS ROBSON, of Kingston-upon-Hull, in the County of York, Cotton
Spinner. "IMPROVEMENTS IN APPARATUS FOR CLEANING CHIMNEYS OR FLUES."
This Invention is intended to be an improvement on any of the methods now in
use for the cleaning of flues or chimneys, and by it, with the greatest ease and the
utmost dispatch, chimneys or flues can effectively be swept by any ordinary domestic
servant.
It consists of a cast-iron bracket, which can be (and is intended to be) fastened
with bolts and nuts to the outsides of any chimney, whether pot, brick, or metal.
This bracket extends longitudinally beyond the top of the chimney sides, say to a
height of about six inches, and then arches over forming in the centre a bridge, in
which is carried an ordinary grooved pulley. This pulley is provided with an
endless cord of chain or wire equal in length to twice the height of the chimney,
and the endless cord or chain is prevented from getting off the pulley by the bridge
of the bracket, which protects it both at the sides and the top, and so precludes
any possible derangement of the cord. Each end of the cord has attached to it an
eye bolt, which is intended to screw into the centre of the boss of the brush both at
the top and the bottom, or spring books may be used to connect the ends of the
chain to the top and bottom of the brush. This arrangement of endless cord
remains permanently in the chimney, the brush only being detached when not in
use. The same brush will, therefore, do for all the chimneys. In new buildings a
small recess can be made at the side of the fire-place to contain the lower part of
the endless cord ready for the servant's hand.
The brush is an ordinary circular one furnished with bristles or whalebone. Both
at the top and at the bottom of the boss is an iron plate, through which and through
the boss a hole is drilled to admit of the cord passing freely through, and at the
same time prevent its coming into contact with the bristles.

page_text: To clean a chimney the eye bolts which are attached to each end of the cord
require to be screwed into the top and bottom of the boss, having first passed one
of them through the hole which, as before stated, is formed through the boss of the
brush. Any person of ordinary strength can then take hold of one side the cord
and draw the brush right through the chimney. The arch of the bracket being
six inches above the top of the chimney, will allow the brush to come quite out of
the chimney, and thus prevent any possible accumulation of soot at the chimney
top, and does not obstruct the draught in tho slightest degree.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said David Thomas and Joseph Thomas Robson in the Great Scal Patent
Office on the 4th October 1876.
DAVID THOMAS, of Upper Tulse Hill, Roupell Park, in the County of Surrey, and

It consists of a cast-iron bracket, which can be (and is intended to be) fastened

top and the bottom; or spring hooks may be used to connect the ends of the chain
to the top and bottom of the brush. This arrangement of endless cord remains
permanently in the chimney, the brush only being detached when not in use.
same brush will, therefore, do for all the chimneys. In new buildings a small recess

The brush is an ordinary circular one furnished with bristles or whalebone. Both
at the top and at the bottom of the boss is an iron plate, through which and through
the boss a hole is drilled to admit of the cord passing freely through, and at the
same time prevent it coming into contact with the bristles.
To clean a chimney, the eye bolts which are attached to each end of the cord
require to be screwed into the top and bottom of the boss, having first passed one
of them through the hole which, as before stated, is formed through the boss of the
brush. Any person of ordinary strength can then take hold of one side the cord
and draw the brush right through the chimney. The arch of the bracket being
six inches above the top of the chimney, will allow the brush to come quite out of
the chimney, and thus prevent any possible accumulation of soot at the chimney
top, and does not obstruct the draught in the slightest degree.
In order that our said Invention may be most fully understood and readily
carried into effect, we will proceed to describe the Drawings hereunto annexed.

page_text: clamped or otherwise securely fixed to the chimney pot, and it carries the grooved
pulley d. is a wire cord; it is attached at one end to the top of the circular
bruslf, and passes up from the brush over the pulley , then descends through a
passage formed for it through the centre of the brush to the bottom of the chimney,
so as to be within easy reach, and it is then again led upwards to the brush, and
is made fast to it on the under side.
The connections between the cord and the brush may be made in any way which
admits of the brush being readily detached and removed after it has been used, and
refixed when it is next required.
Having thus described the nature of our said Invention and the manner of per-
forming the same, we would have it understood that we do not confine ourselves to
the exact details represented on the Drawings, but we claim the construction of
apparatus for cleaning chimneys or flues, substantially as described.
In witness whereof, I, the said David Thomas, have hereunto set my hand and
seal, this 3rd day of October, in the year of our Lord One thousand eight
hundred and seventy-six.
