Improvements in Machines for Washing, Soaping, or Scouring Piece
Goods.
We, DUNCAN STEWART, and ROBERT WALKER, of London Road Iron Works,
Glasgow, in the County of Lanark, North Britain, Engineers, do hereby declare the
nature of this Invention to be as follows, that is to say :-
Our said Invention relates to the class of machines for washing, soaping, or scouring
piece goods in which the fabric gathered together into the form of a "chain" or rope
is passed repeatedly through a vat containing the washing or other liquid and between
squeezing rollers; and our object is to render the washing action more effective and
expeditious.
In carrying out our Invention we add to the machino a roller over which the several
convolutions of the fabric pass just before entering between the squeezing rollers;
and whilst the fabric is passing over this added roller we subject it to a rolling or
rubbing action produced by a concave plate provided with an inner surface of wood
or other suitable material, and made to reciprocate in the direction of the length of
the roller by means of a rapidly rotating eccentric or crank. The acting surface of
the concave plate may be corrugated or otherwise suitably roughened.

Improvements in Machines for Washing, Soaping, or Scouring Piece
Goods.
We, DUNCAN STEWART, and ROBERT WALKER, of London Road Iron Works,
Glasgow, in the County of Lanark, North Britain, Engineers, 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, that is to
say :-
Our said Invention relates to the class of machines for washing, soaping, or scouring
piece goods in which the fabric gathered together into the form of a
"chain" or rope
is passed repeatedly through a vat containing the washing or other liquid and between
squeezing rollers; and our object is to render the washing action more effective and
expeditious.
In carrying out our Invention we add to the machine a roller over which the
several convolutions of the fabric pass just before entering between the squeezing
rollers and whilst the fabric is passing over this added roller wo subject it to a
rolling or rubbing action produced by a concave plate provided with an inner surface
of wood or other suitable material, and made to reciprocate in the direction of
the length of the roller by means of a rapidly rotating eccentric or crank.
acting surface of the concave plate may be corrugated or otherwise suitably
roughened.
The
A machine as made with our improvements is represented on an accompanying
sheet of explanatory drawings, figure, 1, being an end elevation of the machine, and
figuro, 2, a front elevation of a part of it.
At the base of the machine there is a shallow trough or vat, A, which contains
the liquid for treating the fabric and which has fitted in it two rollers, B, round and
under which the fabric, C, is guided so that each convolution of it passes through tho
liquid. The fabric, C, is entered over a guide roller, D, from which it passes to the
further immersed roller, B, then under both rollers, B, and thence upwards between
guide pins, E, fixod on a bar, F. On the ends of the trough or vat, A there are fixed
end frame standards, G, made with bearings for three rollers, H, J, K, the two
latter, J, K, being arranged as a pair of squeezers for expressing the liquid out of the
fabric. The other roller, H, is the additional roller over which the fabric, C, passes
before passing between the squeezing rollers, J, K. After passing between the
squeezing rollers, J, K, the fabric returns down to the trough or vat, A, and passes
under the rollers, B, and through the liquid and then up again to the upper rollers.
In this way the fabric makes several circuits and the several convolutions or loops are
kept properly spaced apart along the rollers by the guide pins, E.
Whilst passing over the added roller, H, the fabric is subjected to the rolling or
rubbing action of a number of wooden bars, L, fixed to concave plates, M, and made
to reciprocate along the roller. The plates, M, havo rods, N, fixed to them and guided

page_text: in eyes in brackets, P, at each end of the machine these guide eyes being elongated
so as to allow the plates, M, to be at different distances from the roller, H, according
to the thickness of the fabric, C, that is being operated on. The plate, M, at one end
of the machine is connected by a rod, Q, to a bellcrank lever, R, centered on a bracket, S,
the other arm of the bellcrank lever being connected by a universal joint to the rod, T,
of an eccentric, U, on a shaft, V, driven by gearing from the shaft of the roller, H.
The rubbing bars, L, are by preference made with corrugations on their acting
surfaces.
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 :-
In machines of the kind heroinbefore indicated for washing, soaping, or scouring
piece goods, providing reciprocating rollers or rubbers to act on the fabric whilst
passing round a roller substantially as herein before described.
