PROVISIONAL SPECIFICATION.
Improvements in or relating to Mechanism for Singeing Circular
and other Brushes.
We, NORMAN KNOWLES, of Egyptian Mill, Bolton, Cotton Spinner, and
WILLIAM PHILIPSON, of Holland Street Iron Works, Astley Bridge, near Bolton,
Engineer and Machinist, both in the County of Lancaster, do hereby declare the
nature of our said invention to be as follows:-
This invention relates to improvements in mechanism for singeing circular and flat
brushes and consists in the construction and means whereby the bristles of circular
and flat brushes can be uniformly and scientifically singed, by which the sharpness
and effectiveness of the same are maintained throughout their entire length, the
latter being utterly impossible under the old or present system of singeing. On a
suitable framework are mounted bearings to receive the circular or other brush or
brushes to be operated upon. To the framesides are secured, in any convenient
manner, slide bars provided with means of adjustment to determine the position of
the singeing bar or block according to the amount required. The slide bars are
constructed to allow of the free movement of a heated bar or block provided with
guides, which can be slid backwards and forwards from end to end with a rod by
hand, or automatically by means of a right and left hand screw or screws, chains, or
other mechanical micans. As the heated bar or block is traversed backwards and
forwards on the slide bars the circular brush or brushes can be rotated by hand or
automatically as desired.

We, NORMAN KNOWLES, of Egyptian Mill, Bolton, Cotton Spinner, and
WILLIAM PHILIPSON, of Holland Street Iron Works, Astley Bridge, near Bolton,
Engineer and Machinist, both in the County of Lancaster, do hereby declare the
nature of our said 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 improvements in mechanism for singeing circular and flat

elevation of upper end of machine framing with one of the slide bars swivelled or
raised to allow of the brush being placed therein or removed therefrom-Fig. 7 in
a part front elevation of our improved machine for singeing flat brushes, and "Fig. 8

In all the figures the same letters are employed to indicate corresponding
parts.
A. A. are the framesides of the machine: B the stay-rod; (1. shaft carrying
the cams D: E slide blocks or bearings: F and G slide bars: II the brush to be
operated upon, and I the singeing bar or block. On the framesides A. A of the
machine are mounted the slide blocks or bearings E to receive the centres of the
circular brush H when placed in the machine to be singed. The latter is effected by
sliding the bar or block T- -when heated-to and fro on the slide burs F and G by
the rod K or its equivalent. The bar or block I is provided with the hole L to
receive the end of the rod K, which may substituted by other means according to
the kind of article or tool employed for moving or sliding the said heated bar or
block 1. The latter is fitted with the guides S to determine its position on the slide
bars Fand i. In the case of eirentar brushes they can be rotated by the hamlle M
when the heated bar or block 1 is being slid on the slide bars Faid G, to allow
of singeing being uniformly and scientifically performed. The slide bar F is secured
to the swivelling ends N by the nuts () to allow of its being lifted, as in Fig. 6, when
a brush is being placed in the machine or removed therefrom. The slide bar F can
he adjusted by means of the screws P in the swivelling ends N operating on the
arts on the upper ends of the framesides A. A. For adjusting the brush II that
is placed in the machine to be singed the slide blocks or hearings E carrying the
same are raised or lowered by rotating the shaft and cains D. The cams D
operate on the projections R secured to the slide blocks or hearing, E.
In constructing our improved machine for singeing flat brushes the slide blocks or
bearings are provided with the bearers T to receive the plate U for supporting
the flat brush Ì as in Fig. 7 and 8.
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 :-
1. Singeing circular and other brushes by means of a heated bar slid to and fro on
slide bars, substantially as described.
2. In a machine for singeing circular and other brushes the use of the adjustable
slide bars, substantially as describeł.
3. In a machine for singeing circular and other brushes the means for adjusting
the brushes to be operated upon, substantially as described.
4. The construction, combination, and arrangement of parts forming our improved
machine for singeing circular and other brushes, substantially as described and illus-
trated by the drawings.
