Improvements in or in connection with Washing and Dyeing
Machinery for Piece Goods.
We JOSEPH HUDSON of Audlin Street Meadow Road Leeds in the County
of York Engineer, and HENRY PALLISER RICHARDSON of Holderness Terrace
Burley Leeds in the County of York Agent do hereby declare the nature of this
invention to be as follows:-
Our invention refers to that class of washing and dyeing machines for piece
goods in which the fabric is passed between a pair of squeezing or drawing
rollers, and has for its object to provide means for automatically stopping the
machine in case the fabric becomes doubled, or folded between the rollers, through
inattention or otherwise; which might result in tearing or damaging the piece.
One of the rollers of such machines is generally driven from a driving shaft
in line with the axle of the roller, by means of a sliding sleeve carrying a couple
of long pins or bolts, which when moved in the proper direction, come in contact
with the projecting lugs or ends of a split brake strap, embracing a pulley on
the axle of the roller.
Now our invention consists in the first place, in utilizing the rise or lift of
the top roller, (when mounting over a doubling or folding of the fabric), to
bring into action a withdrawal of the above mentioned sleeve carrying the pins
or bolts; and thus to disconnect the axle of the driving roller from the driving
shaft. This we effect by connecting the bearings or guide blocks on the axle of
the top roller by means of rods with a pair of bell crank levers, hung to brackets
or lugs on the top of the frame of the machine. The vertical arms of these
levers are connected together by means of a connecting rod. The horizontal arm
of one of the bell crank levers, that on the side next to the driving shaft, is
connected with a vertical rod, which operates a catch supporting a hinged
weighted lever, in such a manner; that on the rise or lift of the top roller, the
weighted lever is liberated. A second lever on the shaft carrying the weighted
lever is connected with the before mentioned sleeve, in such a manner; that the
fall of the weighted lever withdraws the sleeve, throwing the bottom roller axle
out of gear with the driving shaft, thus bringing about a stoppage of the machine.
In the second place our invention consists in utilizing the reduction of speed
of one, preferably the top roller, (occasioned by any doubling, folding, or other
irregularity, which might lead to tearing or damage of the fabric), to bring into
action the withdrawal of the above mentioned sleeve, so as to stop the machine.
For this purpose we arrange that the said roller, by means of a pulley on the
axle of the roller, shall drive a gravity- or spring- centrifugal governor; and we
connect the moving sleeve of said governor with the before-mentioned vertical
rod for operating the catch supporting the above mentioned hinged weighted
lever, and in such a manner; that a reduction from the normal speed of the
governor causes the hinged weighted lever to be released, stopping the machine
as above described.
In the last place our invention consists in the introduction of springs between
the tightening up nut and the ends of the before mentioned split brake strap, so
that the pressure drawing the two halves of the strap together is regulated by
the compression of the springs, whereby a better adjustment of the brake or

page_text: driving power on the pulley is obtained, which reduces or obviates any risk of
breakage of the teeth of the pinion on the driving shaft.
Our improvements are applicable to belt driven as well as to spur wheel driven
machines.

Improvements in or in connection with Washing and Dyeing
Machinery for Piece Goods.
We JOSEPH HUDSON of Audlin Street Meadow Road Leeds in the County
of York Engineer and HENRY PALLISER RICHARDSON of Holderness Terrace
Burley Leeds in the County of York Agent 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 refers to that class of washing and dyeing machines for piece
goods in which the fabric is passed between a pair of squeezing or drawing rollers
and has for its object to provide means for automatically stopping the machine in
case the fabric becomes doubled, or folded between the rollers through inattention
or otherwise; which might result in tearing or damaging the piece.
One of the rollers of such machines is usually driven from a driving shaft in line
with the axle of the roller, by means of a sliding sleeve carrying a couple of pins
or long bolts, which when moved in the proper direction come in contact with the
projecting lugs or ends of a split brake strap embracing a pulley on the driving
shaft.
Now our invention consists in the first place in utilizing the rise or lift of the top
roller, when mounting over a doubling or folding of the fabric, to bring into action
a withdrawal of the abovementioned sleeve carrying the pins or bolts; and thus to
disconnect the axle of the driving roller from the driving shaft. This we effect by
connecting the bearings or guide blocks on the axle of the top roller by means of rods
with a pair of bell crank levers, pivotted to brackets or lugs on the top of the frame
of the machine. The vertical arms of these levers are connected together by means
of a connecting rod. The horizontal arm of one of the bell crank levers, that on
the side next to the driving shaft, is connected with a vertical rod, which operates
a catch supporting a hinged weighted lever, in such a manner; that on the rise or
lift of the top roller, the weighted lever is liberated. A second lever, on the shaft
carrying the weighted lever, is connected with the before mentioned sleeve, in such
a manner; that the fall of the weighted lever withdraws the sleeve, throwing the
bottom roller axle out of gear with the driving shaft, thus bringing about a
stoppage of the machine.
The invention may be modified by dispensing with the catch, and connecting the
vertical rod directly to the lever, above designated the weighted lever, which
however in this case is not weighted, and the lever is opposite handed to the
weighted lever. This modification is not quite so sensitive as the first described
arrangement, inasmuch as in the former the lifting of the roller merely effects the
release of the aforesaid lever, whilst in the latter it lifts the lever and moves the
Bleeve.
In the second place our invention consists in utilizing the reduction of speed of
one, preferably the top roller, (occassioned by any doubling folding or other
irregularity which might lead to tearing or damage of the fabric), to bring
into action the withdrawal of the above mentioned sleeve, so as to stop the

machine. For this purpose we arrange that the said roller, by means of a pulley
on the axle of the roller, shall drive a gravity, or spring centrifugal governor;
and we connect the moving sleeve of said governor with the before mentioned.
vertical rod for operating the catch supporting the above mentioned hinged
weighted lever, and in such a manner, that a reduction from the normal speed of
the governor, causes the hinged weighted lever to be released, stopping the
machine as above described.
In the last place our invention consists in the introduction of springs between
the tightening up nut and the ends of the before mentioned split brake strap, so
that the pressure drawing the two halves of the strap together is regulated by the
compression of the springs, whereby a better adjustment of the brake or driving
power is obtained; which reduces or obviates the risk of breakage of the teeth of
the pinion on the driving shaft.
Our improvements are applicable to belt driven as well as to spur wheel driven
machines.
And in order that our invention and the manner in which the same is to be
performed may be more readily and clearly understood, we have annexed hereto
the accompanying drawing; in which Fig. 1 is a side elevation, and Fig. 2 an end
elevation of a cloth washing machine to which our invention has been applied.
a indicates the side frames of the washing machine. b is the bottom roller,
and the axle of the same. c is the top roller, and c¹ c¹ are loose collars or
bushes on the axle of the roller. The axle 6' is in line with the main driving
shaft d. e is the usual brake strap and pulley on the end of the shaft d, and e' e¹ are
the lugs on the strap. is the sleeve mounted with a groove and feather arrange-
ment on, and capable of sliding along the roller shaft b². gy are long pins or
bolts, which pass through slots or guide holes in the ends of the carrier ; this
latter being fixed to the end of the axle b'. When the sleeve is pushed towards
the brake strap, the ends of these long pins 9 come in the way of the lugs e¹ of the
brake strap, as shewn in the drawing, and the axle b' is then driven from the
driving shaft d.
•
The collars or bushes c' on the axle of the top roller are connected to the
horizontal arms; of the bell crank levers jj, by the vertical rods or bars ; the
vertical arms being connected by the connecting rod i. The horizontal arm j; on
the side of the machine next the driving gear, is connected with the vertical rod k;
which at its lower end is attached to the catch m. The catch m when in the
position shewn, supports the weighted lever n by means of the short sneck piece n¹
on the shaft o in the raised position; but when the catch is drawn back by the
vertical rod k, it allows the weighted lever n to fall. The weighted lever is keyed
on the shaft o, and a forked lever p is also keyed ou the same shaft o; the end of
the fork lever p carrying a pair of runners, which fit in the groove round the
Bleeve f
It will be evident that when the top roller is lifted by any doubling of the
fabric, as above referred to, that this motion is transmitted to the vertical rod k,
which pulls back the catch m, releasing the weighted lever n, and this latter
falling, draws back the sleeve fand pins 9 throwing the machine out of gear.
g
In the modification above referred to, the lower end of the vertical rod k is
attached directly to the end of the lever n; which in this case is not weighted,
and is on the opposite side of the axis o to that on which it is shewn in the
drawing.
For the purpose of utilizing the reduction of speed of say the top roller for
bringing about a stoppage of the machine, we provide the spring centrifugal
governor q, and connect the moveable sleever on the spindle of the same to the
rod k¹ by means of the lever s, shaft o¹ and lever t. The spindle of the governor
is provided with a small pulley, indicated in Fig. 1 by the dotted circle u; which
is driven by belt, cord or chain from the large pulley, (indicated in Fig. 1 by the
dotted circle ), on the end of the axis of the top roller c.
Fig. 3 shews at x the springs for regulating or softening the blow of the lugs e¹

page_text: and the
of the brake strap e against the pins g. The spring, between the bolt
circular box w, is still further compressed when the end of the bolt y strikes
against the side of the pin g, as shewn in the drawing. The bolt z serves to
prevent the strap e becoming too loose on its pulley.
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 :-
1. Washing and dyeing machines for piece goods characterized by the use of
mechanism whereby the rise or lift of the top roller, occassioned by a doubling
or other irregular increase in the thickness of the piece passing between the top
and bottom rollers, is utilized for bringing about a stoppage of the machine.
2. In washing and dyeing machines for piece goods, the combination of vertical
rods connected to the axle of the top roller c, levers jj, connecting rod i, and
vertical rod k; the latter being connected to mechanism controlling or actuating
thereby the forked lever p, for bringing about a withdrawal of the sleeve for
of a belt fork on the rise or lift of the top roller.
3. In washing and dyeing machines for piece goods the arrangement and
combination of belt fork rod or the sleeve f, lever p, shaft o, weighted lever n, and
-sneck piece n¹ and catch m, with the vertical rod k, and means for lifting the latter
on the rise of the top roller c.
4. In washing and dyeing machines for piece goods, the combination of a belt
fork rod on the sleeve f, lever p, shaft o, and a second lever ou the shaft o,
-connected to the lower end of the vertical rod k, with means for lifting the
latter on the rise of the top roller c.
5. In washing and dyeing machines for piece goods, the use and construction
of automatic stop mechanism substantially as and for the purpose herein set forth.
6. In washing and dyeing machines for piece goods the means for automatically
stopping the machine by and on a reduction of the speed of the top roller
substantially as herein set forth.
