Improvements in Machinery for Mordanting, Dyeing, Washing, and
Scouring Hanks of Yarn.
I, WILLIAM HENRY THORPE,, of 2, Royd Terrace, Halifax, in the County of
York, Engineer, 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 :--
This invention relates to a new arrangement aud construction of mechanism for
mordanting, dyeing, washing off, and scouring hanks of yarn in a continuous
process.
Such being the nature and object of my invention I will now proceed by the
aid of the annexed sheets of drawings to describe my improved machine more
fully.
Fig. 1 of the accompanying drawings is end elevation of my improved machine
and Fig. 2 side elevation. A is the mordanting cistern,, B the dyeing cistern
and C the washing off cistern. The rollers for carrying hanks are shewn at D, such
rollers being supported in the longitudinal frame or carriage E arranged at each
side of the machine. The longitudinal frames E are borne or carried by studs
passing through pulleys or tram wheels F which rest and ride upon angle iron
rails G connected to the inside of the cisterns. The frame or carriage E is
reciprocated backward and forward in the liquor by means of an adjustable
connecting rod H attached to face plate I caused to revolve by the longitudinal
shafts J and in order to give a partial rotation to the bank carrying rollers and to
the hanks thereon there is fixed on the axle on one end of each roller, a pinion
wheel L gearing with each other. The pinion wheels L are driven by spur
wheels M fixed on the stud of the tram wheel F so that when the connecting rod H
traverses the carriage backward and forward through the liquor, the pinion wheels
give a partial backward and forward rotation to the hank, carrying rollers
consequently the position of the hanks upon the roller is changed.
In order to keep the hanke in a distended condition and apart from each other so
as to prevent felting and knotting, I place in the bottom of each hauk, a roller N
and upon each roller 1 place a notched bar Oat each side of the machine, the said
bar being kept rigid by means of a pawl a (see Fig. 3) taking into notches 6 on the
vertical rods P by which means it will be seen that the hanka are kept in a
distended state and cannot be felted or knotted with adjoining hanks. When the
hauks have been sufficiently stained, in cistern. A the carriage, together with the
banks, are lifted by pulley blocks and transferred and lowered into the dyeing
vessel B, when the operation of oscillating the carriage backward and forward is
repeated in the dyeing liquor, and when the banks are sufficiently dyed, the carriage
is raised by the pulley blocks and transferred to the washing off cistern C, and if
two carriages are in use, the several processes can be performed very expeditiously
and at a small cost. If necessary the angle iron rails G instead of being connected
to the inside of the cisterns as shewn in the drawings, such angle iron rails could be
fixed on the top edge of each cistern so that the latter could contain a larger
quantity of liquor.
In order to impart to the hauk carrying rollers a continuous rotary motion,
instead of partial rotary motion as already described, I may give the said rollers a
continuous rotary motion; to do this 1 place the tram wheel F loosely on its stud
so that the carriage E can ride backward and forward without imparting rotary
motion to the pinion wheels L; I also employ a worm R (see Figs. 5 and 6) placed
onto a cross shaft S made with a key bed or groove c. The worm wheel Tand also

page_text: spur wheel U are fixed upon the same shaft, the latter spur wheel gearing with one
of the pinions Lou the end of the hank carrying rollers, therefore the said worm R,
through the intervention of the other wheels, will give a continuous rotary motion
to the bank carrying rollers, and the notion will be imparted to them whilst the
carriage is being traversed backwards and forwards in the liquor, this being
permitted to be done by means of the groove cin shaft S.and a key fixed in the
worm Ras will be well understood by those conversant with mechanics.
.
By the construction and combination of mechanism as above described and
illustrated in the accompanying drawings, the machine will be found to be
peculiarly and well adapted for the various processes enumerated, and as the hanks
are in a constant state of agitation in the liquor, there is no possibility of the
colouring matter lodging in the bottom of the cistern, consequently the liquor will
'be of the same shade or strength and fully utilized:
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In a dyeing or scouring machine, the use of hank carrying rollers and
rollers at the bottom of the hanks, the latter being kept in a distended state by
notched bar O, substantially as shewn and described.
Secondly. In a dyeing or scouring machine, the use of hank carrying rollers and
rollers at the bottom of the hanks, the latter being kept in a distended state by
notched bar O, in combination with pawl a and ratchet b as shewn and described.
Thirdly. In a dyeing or scouring machine, the combination of carriage E tram
wheels pinious L, said carriage being traversed backwards and forwards by
connecting rod H, all as described.
Fourthly. In a dyeing or scouring machine, the use of bank carrying rollers,
supported by a carriage traversed backwards and forwards by connecting rod,, in
combination with pinion wheels and worm R for imparting, a continuous rotary
motion to the hank carrying rollers.
Fifthly. The general combination and arrangement of parts comprising a machine
for mordanting, dyeing, washing off or scouring hanks of yarn in manner
substantially as shewn and described.
