Pile Fabrics and the Machinery therefor.
We, THOMAS SCHOFIELD and FREDERIC BARKER, both of Cornbrook, Manchester,
in the County of Lancaster, Mechanical Engineers, do hereby declare the nature of
this invention to be as follows :-
:-
Our invention consists of Improved Brushes, and an arrangement of rollers, by
which each brush is made to act on three of its sides, instead of one; as shown in
accompanying drawings. The description of machines generally in use of this class
is as follows:-The fabric is conducted over a number of rollers placed horizontally
in machine frame, as shown in Fig. 1; the rollers A, being the bearing rollers on
which the cloth is acted upon by brushes B.; the sections C. C. are guide bars to
steady and direct the motion of brushes B. A to-and-fro motion is imparted to the
brushes by means of straps attached to ends of brushes, and to rocking levers I placed
under machine; these rocking levers being worked by a crank and connecting rod D'
from shaft at top of machine.
The object of our invention is to utilize the sides of brushes B., working
against the guide-bars C. C., as brushes; and to effect this we substitute bearing
rollers instead of the guide-bars; as shown in Fig. 2; A. being main bearing
roller as in Fig. 1; and E. E. being side rollers to replace the guide-bars. To allow
and compensate for wearing down of brushes F. F. F., the sides F. are hinged on
to the bottom block F., and are adjusted by means of screws and wedges G. and G¹.
The rollers E. E. are also adjustable. The means used to give to-and-fro motion to
brushes being similar to that now in use, need no special description.

We, THOMAS SCHOFIELD, Dyer, and FREDERIC BARKER, Engineer both of
Cornbrook Manchester in the County of Lancaster, 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 :—
Our Invention consists of Improved Brushes and arrangement of Rollers by which
each brush is made to act on two or three of its sides instead of one, as shown in the
accompanying drawings. The method generally in use for Brushing Pile Fabrics is
as follows;
The fabric is conducted over a number of rollers placed horizontally in a Machine
frame as shown in Fig. 1, in accompanying drawing, the rollers A being the bearing
rollers over which the fabric passes and on which the fabric is acted upon by the
brushes B, the sections C, C, are guide bars to steady the motion of the brushes, the
rollers are binding rollers under which the fabric passes in order that it
firm and tight on the bearing rollers A, the brushes B are pulled backwards and
forward across the bearing rollers A by means of straps attached to the ends of
brushes and to a treadle motion E or rocking levers fixed under the Machine.

The object of our invention is to utilize the sides of brushes B now working against
guide bars C, C, as brushes; and to effect this we substitute bearing rollers in place
of the guide bars C, C, as shown in Fig. 2, which shows the brushes B, B1, B2, working
on three sides, A being the bearing roller as in old method; F, F, being rollers
replacing side bars C, C. To allow for wear and tear of bristles the side brushes B1, B2,
are hinged on to bottom brush B and can be adjusted to bearing rollers F, F, by
means of screws and wedges G or by a simple spring, the rollers F, F, are also
adjustable the means used to give motion to the brushes are same as in old Machine
and need no special mention.
Fig. 3 shows the method of brushing on two sides of the brush, the difference to
the triple arrangement being that the arrangement of bearing and binding rollers are
exactly as in old Machine; we can also use or dispense with the guide bars C, C,
shown in section, they however when used are placed over the centre of bearing
rollers A instead of between as in Fig. 1. It will thus be seen that in a Machine of
similar size and construction to the old one we are enabled by our Improved brushes
and arrangement of rollers to brush the fabric twice or three times as often as can be
accomplished in one run on the old Machine.

page_text: The method for drawing the fabric through the Machine and Plaiting it down, being
the same as in old Machine and needs no special mention.
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. The Improved Brushes and arrangement of rollers by which each brush is made
to act on two or three of its sides instead of one.
2. The arrangement of hinges and screws or springs by which as the side brushes
wear, they may be adjusted to the rollers and the mechanism for effecting the same,
substantially as and for the purpose herein shown and described.
