IMPROVEMENTS IN CARDING ENGINES
Year: 1885

page_text: I THOMAS SMART of North Woodchester near Stroud, Glos. Foreman of Carding.
Engines do hereby declare the nature of my invention for IMPROVEMENTS IN
CARDING ENGINES to be as follows:-
The object of this Invention is to prevent the waste of wool which occurs in the
process of Carding, through the Fly, throwing a considerable quantity out from
the Engine, which being scattered about the Shop is either wholly lost or much
depreciated in value. The quantity thrown out varies greatly with different kinds
of wool and the condition in which it is worked.
To effect this purpose I use a round fibred brush working in connection with the
Fly and the Doffer, which working at a much slower speed and in an opposite
direction to the Fly and in the same direction as the Doffer gathers all the fibres of
Wool (that the Fly would otherwise blow into the Shop) and deposits it on the
Doffer which revolving in the same direction takes it in to the Engine again,
therby saving a great loss of wool.
The revolving brush may be made of bristle, or (card wire set at any angle to
avoid its getting clogged up with wool) or any other suitable material.

page_text: the Engine, which being scattered about the Shop, is either wholly lost or much
depreciated in value, the quantity thrown out varying greatly with different kinds
of wool and the condition in which it is worked and in order that my said
Invention, and the manner of performing the same may be properly understood
I hereunto append a Sheet of Explanatory Drawings.
Figs 1. & 2 show side & front elevations of portions of a Carding Engine to
which the New Revolving brush No 1 is attached. Fig. 3. shows an enlarged end
view of the brush covered with card filleting. Fig. 4 shows an enlarged end view
of a bristle brush.
From these views it will be seen that the brush consists of a Roller covered with
card, or with bristles.
.
I prefer to place the brush between the Fly or Swift and the Doffer but it may
be placed between the Fly and the Cylinder as shown by the dotted circle 2.
If card is used, angle card must be put on in the direction shown in Fig. 3 and it
is essential that the surface speed of the card shall be greater than the surface speed
of the Doffer or Cylinder so that the wool which is thrown off by the Fly and
caught by the brush shall be cleared off it again by the Doffer or Cylinder. The
New Brush may be driven in any convenient way, the most usual being either
from the Fly or Cylinder Shaft, as shown in Figs. 1 & 2.
The brush runs in Bearings not shown which are ajustable in either direction.
In order to prevent the wool working out endways from the brush and the Fly
I fit plates at each end of the brush, &c. as shown at 3. Fig. 1.
Having now particulary described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare what
I claim is
1.-The use of a Revolving Brush covered with bristles and placed between the
Fly or Swift & the Doffer or Cylinder, so that the greater proportion of the wool
thrown off by the Fly is caught by the Brush and laid on the Doffer or Cylinder
again.
2. The use of a Revolving Roller covered with Angle Card, put on as shown in
Fig. 8. The surface speed of the Card being greater than that of the Doffer.
3.-The use of fixed plates at the ends of the Revolving Brush as shown at 3.
Fig. 1. to prevent the wool working out endways.
