PROVISIONAL SPECIFICATION.
Improvements in Machines for Dyeing, Bleaching, or otherwise
Treating Fibres in a Raw, Spun, Woven, or Intermediate State
of Manufacture.
I, AUGUST GRAEMIGER, of Bent Street, Cheetham, Manchester, in the County of
Lancashire, Chemist, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in that class of machines for dyeing,
bleaching, scouring or otherwise treating cotton, wool, silk or other animal or
vegetable fibres in a raw, spun, woven or intermediate state of manufacture, in which
the liquor is forced or drawn through the fibres by means of a pump.
The object of my invention is the employment of a pump or cylinder containing a
piston, which latter carries or is composed of the fibres to be treated and which when
actuated causes the liquor to be drawn or forced through from one side of the same
to the other, either in a continuous or intermediate manner.
This may be accomplished in various ways.
The said cylinder may be formed open and employed in a liquor tank or it may be
closed and employed separately, suitable pipes and valves or taps being provided to
permit of circulating the liquor. The said piston is either formed hollow, with a
perforated or skeleton face, or it may consist of a perforated disc only, unto which
the fibres to be treated are placed, or the latter themselves may serve as the piston by
suitably securing the same to the piston rod, preferably by means of perforated discs
or frames.

COMPLETE SPECIFICATION.
Improvements in Machines for Dyeing, Bleaching, or otherwise
Treating Fibres in a Raw, Spun, Woven, or Intermediate State
of Manufacture.
I, AUGUST GRAEMIGER, of Bent Street, Cheetham, Manchester, in the County of
Lancaster, Chemist, 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:—
My invention relates to improvements in that class of machines for dyeing,
bleaching, scouring or otherwise treating cotton, wool, silk or other animal or
vegetable fibres in a raw, spun, woven or intermediate state of manufacture, in
which the liquor is forced or drawn through the fibres by means of a pump.
The object of my invention is the employment of a pump or cylinder containing a
piston, which latter carries or is composed of the fibres to be treated and which when
actuated causes the liquor to be drawn or forced through from one side of the same
to the other, either in a continuous or intermittent manner.
This may be accomplished in various ways.
The said cylinder may be formed open and employed in a liquor tank, or it may
be closed and employed separately, suitable pipes and valves or taps being provided
to permit of circulating the liquor. The said piston is either formed hollow, with a
perforated or skeleton face, or it may consist of a perforated disc only, unto which

page_text: the fibres to be treated are placed, or the latter themselves may serve as the piston by
suitably securing the same to the piston rod, preferably by means of perforated discs
or frames.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a vertical section,
T
Dan alevation of the lower part of the vessel or cylinder. with liquor tank in
Fig. 4 is also a vertical section and
Fig. 5 a plan of the machine showing its application for wool top dying.
A is the base, B tbe vessel or cylinder, C the piston and D the liquor tank of the
machine.
The piston C composed of or carrying the fibres to be treated, may be employed in 1
'an open vessel or cylinder B, as illustrated in Figs. 1, 2 & 3, or in a closed one
employed separately, as shown in Figs. 4 & 5.
The fibres to be treated may be placed into a hollow removable piston, resting on a
shoulder b, formed on the piston rod c, see Figs. 1, 2 & 3, and the face a of which is
perforated and centrally formed with a hollow perforated boss d onto which is secured,
preferably by means of a cotter e, passing through the same and the piston rod c, a
frame or perforated disc a³, which serves to prevent the fibres to be treated from
leaving the hollow piston C.
In lieu of treating the fibres in a hollow piston C as described, they may be placed
on a frame or perforated disc a as shown in Figs. 4 & 5, in which case the fibres
constitute the piston C, where the form of the fibres in which they are treated will
permit it, another perforated disc or frame a¹ being placed on the top thereof, similar
as shown in Fig. 1.
The vessel or cylinder B is mounted on a base A and when open at one end, see
Figs. 1, 2 & 3, employed inside a liquor tank D, furnished with an inlet hand
outlet and steam pipe k, the piston rod c passing through a stuffing box / employed
in the bottom of the liquor tank D. The closed end of the vessel or cylinder B is
furnished with an inlet and outlet valve m & n in communication with a two way
tap o and pipe p in connection with the liquor in the tank D.
Fig. 1 shows the piston C at the end of its outstroke, the liquor having been
drawn or permitted to run into the vessel or cylinder B from the tank D through
the pipe n, tap o, pipe m² and valve m. On the return stroke of the piston C the
valve m is closed automatically by the pressure of the liquor, which causes the same
to be forced through the perforations in the piston face a and fibres under treatment
and frame or disc a¹ to the other side of the piston C. Communication is then cut
off by means of the tap o, between the lower end of the vessel or cylinder B and the
liquor in the tank D, and thereby opened between the latter and the valve n. The
next outstroke of the piston C closes the valve n and produces a vacuum in front
thereof in the vessel or cylinder B which draws the liquor from the tank D through
the open end of the vessel or cylinder B and the piston C or fibres to be treated to
the other side thereof and on its return stroke opens the valve n and returns the
liquor into the tank D, thus thoroughly impregnating the fibres. This operation may
be repeated as often as deemed necessary.
When employing a cylinder with both ends closed, see Figs. 4 & 5, the upper end
thereof is made readily removable for the purpose of facilitating the substitution of
the fibres to be treated and the bottom end furnished with an inlet and outlet h & i
and valve h¹ & i¹, respectively, which are closed when the piston C is in action and
through which the liquor enters and leaves respectively, or may be replenished
periodically. On the piston U being actuated the liquor in the vessel or cylinder B
forces its way through the same and the fibres under treatment alternately from one
side thereof to the other, thus thoroughly impregnating the same with liquor.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
"In machines for dyeing, bleaching, or otherwise treating fibres in a raw, spun,
woven or intermediate state of manufacture"
1st. A closed liquor vessel or cylinder B, with readily removable end f, liquor
inlet and outlet pipe and valves i, h, i¹, h¹, containing a reciprocating piston C,
composed of or carrying the fibres to be treated, adapted to force the liquor through
the same, alternately, from one side thereof to the other, thereby impregnating the
fibres under treatment with liquor, substantially as set forth with reference to Fig. 4.
2nd. An open liquor vessel or cylinder B with automatically operated liquor inlet
and outlet valves & n, containing a reciprocating piston C, composed of or
carrying the fibres to be treated and adapted to force or draw the liquor through the
same alternately from one side thereof to the other from a liquor tank D surrounding
the vessel or cylinder B and thereby impregnating the fibres, to be treated, with
liquor, substantially as set forth with reference to Fig. 1.
