" IMPROVE-
MENTS IN MACHINERY FOR WRINGING PURPOSES, AND FOR RECOVERING THE
MATTERS WRUNG OUT." A communication from abroad by Friedrich Bernhardt, of
Fischendorf, in the Kingdom of Saxony.
The Invention has for its object to press out soap, grease, or other substances
from woven fabrics, wool, yarn, or other compressible material, and to recover the
said substances so wrung in order to use them again. It is especially applicable
for recovering soap and grease from wool, yarn, or endless woven fabrics, which
have been charged with soap for washing, where the pressed out liquid containing
soap and grease can be used again after the addition of a suitable quantity of
alcali; and it consists chiefly of two revolving cylindrical rollers of which the
lower one revolves on a fixed preferably horizontal axis supported on one side of
the roller, the axle of the upper roller being carried in a fork pressed down by a
spring (preferably a spiral spring encased in a cylinder), which during the operation
is compressed by a piston and cam or other suitable contrivance placed in its
position by means of a lever moved by hand, either directly or indirectly, and if

spring is released, the material to be pressed placed between the rollers, pressure
applied, and the rollers revolved by means of spur wheels fitting in their axles, one
of which may be driven by a pulley or other means. Before going through the
rollers the material passes through a narrow tube or guide, which is suspended from
the axle of the upper roller in such a manner, that it can be turned round the
latter as well as round an intermediate joint, and be lifted or lowered together
with the said roller. The machine is also provided with guide rollers for guiding
the material into and out of the press rollers, and may be made wholly or partly of
metal or other suitable material.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVE-
MENTS IN MACHINERY FOR WRINGING PURPOSES, AND FOR RECOVERING THE
MATTERS WRUNG OUT." A communication from abroad by Friedrich Bernhardt, of
Fischendorf, in the Kingdom of Saxony.
The Invention has for its object to press out soap, grease, or other substances
from woven fabrics, wool, yarn, or other compressible material, and to recover the
said substances so wrung in order to use them again. It is especially applicable
for recovering soap and grease from wool, yarn, or endless woven fabrics which
have been charged with soup for washing, where the pressed out liquid containing
soap and grease can be used again after the addition of a suitable quantity of
alcali; and it consists chiefly of two revolving cylindrical rollers of which the lower
one revolves on a fixed preferably horizontal axis supported on one side of the
roller, the axle of the upper roller being carried in a fork pressed down by a spring
(preferably a spiral spring encased in a cylinder), which during the operation is
compressed by a piston and cam or other suitable contrivance, placed in its position
by means of a lever moved by hand, either directly or indirectly, and if desirable
with the assistance of a counterweight. For working the machine the spring is
released, the material to be pressed placed between the rollers, pressure applied, and
the rollers revolved by means of spur wheels fitting in their axles, one of which
may be driven by a pulley or other means. Before going through the rollers the
material passes through a narrow tube or guide which is suspended from the axle
of the upper roller in such a manner, that it can be turned round the latter as well
as round an intermediate joint, and be lifted or lowered together with the said
roller. The machine is also provided with guide rollers for guiding the material
into and out of the press rollers, and may be made wholly or partly of metal or
other suitable material. The construction of the machine will be further described
and more fully understood by reference to the accompanying Drawings, Sheets I. and
II., in which Figure I. represents a front elevation, the marginal disc of the lower roller
being partly removed, and the appliance for guiding the driving belt omitted; Figure
II., a side elevation with section through line A, B, of Figure I.; Figure III., a plan';
Figure IV., a partial front elevation with the upper roller lifted; Figure V., side
elevation of the guide channel C; Figure VI., section of the latter through line D, F ;
Figure VII., cross section of the same through line G, H; Figure VIII., detail view of
ring ; Figures IX. to XVI. show various arrangements for producing the pressure,
and for raising or lowering the movable roller b by a lever. By supporting the '
roller a on one side only while the other roller b can easily be lifted, an endless
fabric may be inserted without opening the seam, &c. In turning the axle o by
means of the lever p¹ which is balanced by a counterweight p³, the cam n can be
placed in the position shown by dotted lines in Figure II. In bringing the cam into
the position just described, the fork e with the roller b is lifted under the influence
of the counterweight p" and the cam d to the position shown in Figure IV., after
which the fabric to be wrung can be placed between the rollers. The lowering of
the roller b is effected by the two cams n¹, n¹, which are firmly connected with n
(and which move against the rollers 1, 1, applied on the piston 7), when the lever p
is brought back from the dotted position into its original place; by this motion of
the cam n the strong spring x between the two pistons and h is again com-
pressed. The spring and pistons are arranged as follows:-A tube is cast on
the fork e and carries the piston h which is made adjustable by means of the
nut i. Upon the piston follows the spring capable of being compressed by means.
of the second piston 6, the spindle m, which latter is guided in the tube of e and

page_text: e,
the
the nut m. The machine frame z encloses the spring and accessories in shape of a
cylinder. A chief part of the machine is the channel c attached to the fork e and
serving to guide the fabric to be pressed, so as to prevent any folds passing upon
the rim of the roller a. The channel c may be turned round the axle of the roller
b as well as round the bolt ct. It can be opened from below by a simple lid c
and on the roller b being lifted it is raised by means of the pin c on the fork
lever c., and the suspension rod C. In lowering the fork e with the pin c', the
channel c follows the motion and comes into the position shown by Figure I. To
prevent the fabric being clipped near the hinge of the channel c by shutting the
lid, one side of the channel is provided with several projections (preferably cast on)
which pass through corresponding slits of the lid c, and protect the slit formed
between the opened hinge and the channel c. In order to prevent any injury
arising from the projecting edge of the lid c, on the side of the hinge, the ring c, is
applied. To the side of the roller a is attached the spur wheel k¹ gearing into the
wheel, which latter is rigidly connected with the roller b; a stoppage of b can
therefore not occur when the spring a is compressed. In order to counteract the
lateral pressure on the fork e caused by the wheels k¹, h, the axle of b is guided
in a slot be of the machine frame z; y is a roller usually attached to the washing
machine; the dye trough or other convenient supports 8, t, u, v, w, designate the
mechanism for guiding the driving belt. The machine or more especially the
roller a is set in motion by the pulleys r, r, and the spur wheels q, q. The
mechanism for producing or removing the pressure as well as for lifting or lowering
the moveable roller b by means of a lever can be varied without departing from
the principle of this Invention. In the construction shown by Figures IX. and X.,
the counterweight balancing the roller b is applied on the lever g, and since the
other end of is connected with the fork e by the rod f, the weight removes the
roller b from a (Figure X.), as soon as the pressure caused by the lever p¹ ceases. A
link p is also attached to the lever pl capable of turning on a pin and enclosing the
upper pin of the suspension rod f. The roller b is lowered in the following
manner: As soon as p¹ is drawn down by the rod p,, the slide pe presses from the
top on the rod f, at the same time raising the counterweight and causing the
roller to fall. By the cam n on the shaft o the roller b and lever g¹ are finally
brought into the position shown in Figure X. In Figures XI. and XII. the counter
weight p³ is made sufficiently large to balance the lever pl as well as the roller b,
the fork e, and the rod f¹. The rod f' encloses with the slide at its upper end a
bolt attached to p', which bolt lifts the rod fl with the fork e and roller b as soon
as the lever pl is lifted. In the arrangement shown by Figures XIII. and XIV., the
slide p is replaced by the bellcrank lever' P. In the arrangement shown by
Figures XV. and XVI., the counterweight p is replaced by the spiral spring resting
upon the ring h', and acting when the cani n assumes the position shown by dotted
lines in Figure XVI. The effect of x is removed by the two cams n', n², firmly
connected with n, and acting upon the rollers U,, with which the upper piston ỉ is
provided. Claims.-1. A wringing machine for endless fabrics.
2. The con-
struction of the channel c, the whole substantially as described and illustrated.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Twenty ninth day of October, A.D. 1879.
