Improvements in Machinery for Dyeing, Scouring, and Bleaching
Hanks or Skeins of Yarn.
I, WILLIAM HENRY THORPE, of 2, Royds Terrace, Halifax, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to prior Letters Patent granted to me bearing date
the 10th day of October A.D. 1894 No. 19226 and my present invention consists in
further improvements for perfecting the apparatus therein described.
According to my present invention the carriage or the whole of the apparatus
carrying the hank carrying rollers are made not only to traverse or reciprocate
backwards and forwards in the vessel by an arrangement of cranks and levers but the
said carriage is also made to ride over a semi-circular surface so that whilst the hanks
are traversed backwards and forwards through the vessel they rise and fall therein
to the extent of the semi-circular surface, consequently the hanks rise and fall in the
tank in addition to traversing consequently the liquor is kept in a constant state of
agitation and the position of the banks in the liquor is being constantly changed.
The carriage carrying the hanks is provided with feet so that when the hanks have
been lifted out of the machine and placed upon the floor they rest upon the feet
which permits the treated hanks to be readily removed and fresh ones substituted.
I also place in the carriage a series of horizontal bars placed between each section
of hanks so that the hanks are kept separate and whilst they are traversing up and
down there is no frictional contact between them. The hanks are placed upon
endless chains or webs composed of cloth, wirework, or flexible network constructed
of either rubber, aluminium phosphor bronze, or I may use perforated cloths or sheets
made of metal or any other substance or material. By the use of the endless cloths,
wirework, web, or network, or other flexible material or substance, I am enabled to
dispense with rollers, or otherwise, at the bottom of the hanks which have hitherto
been employed to weigh them down in the liquor. The mechanism herein described
can be applied to new cisterns or to any existing cisterns.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has reference to prior Letters Patent granted to me, bearing date
the 10th day of October A.D. 1894 No. 19226 and my present invention consists in

are
According to my present invention, the carriage or the whole of the apparatus
carrying the hank carrying rollers is made not only to traverse or reciprocate
backwards and forwards in the vessel, by an arrangement of cranks and levers, but the
said carriage is also made to ride over a semicircular surface, so that whilst the hanks
traversed backwards and forwards through the vessel they rise and fall
therein to the extent of the semicircular surface consequently the liquor is kept
in a constant state of agitation and the position of the hanks in the liquor is
being constantly changed. The carriage carrying the hanks is provided with feet so
that when the hanks have been lifted out of the machine and placed upon the floor
they rest upon the feet which permits the treated hanks to be readily removed and
fresh ones substituted.
I may also place in the carriage a series of horizontal bars placed between each
section of hanks so that the hanks are kept separate and whilst they are traversing up
and down, there is no frictional contact between them.
In order that my invention may be fully understood reference is hereafter had
to the annexed drawings forming a part of this Specification in which :-
Fig. 1 is longitudinal elevation of machine for dyeing, scouring and bleaching
hanks or skins of yarn constructed according to my invention, the machine being
broken into three parts to shew the centre and two end portions thereof, which are
sufficient to fully illustrate my invention.
Fig 2 is transverse elevation of the right hand end of Fig. 1.
Fig 3 is sectional end elevation of the carriage or frame carrying the rollers for
supporting the hanks.
Figs. 4 and 5 are side elevations of the bearings in which the hank carrying rollers
are journalled, and
Fig. 6 is a sectional plan taken on line 1-2 of Fig. 3.
Referring to the drawings letter a represents the dye vessel at one end of which is
the main driving shaft 6 driven by strap c and communicating motion through worm d
and worm wheel e to the transverse shaft f journalled in bearings in brackets f¹ bolted
to the end of the vessel a. At each side of the vessel a and pivotted on studs g, g¹, g²
secured to brackets bolted to the sides of the vessel a near the bottom thereof, are
three or other suitable number of vertical levers h, h¹, h2 which are connected together
at a suitable height by a horizontal lever or bar i. To the central levers h¹ of each set
of side levers or it may be to the end levers of each set are secured one end of
connecting rods j, whose opposite ends are attached to crank arms k keyed on each
end of the cross shaft f, the rotary motion of said crank arms giving through the said
connecting rods, an oscillatory or pendulous motion to the two sets of side levers h, h¹
and h².
At the upper ends of each of said levers h, h¹, h² are open ended of forked bear-
ings h³ into which are adapted to enter and journal themselves cross shafts secured
in arms m¹ extending up from and integral with or bolted to a rectangular carriage
or frame m which is thus supported and carried by said pendulous levers h, h¹³, h².
Journalled in bearings in one side of the carriage or frame m are a number of short
studs or shafts n¹ on whose outer ends are secured pinions n gearing one with the
other from end to end of the carriage or frame and receiving their motion by spur
gearing n², n³, from a shaft or stud o carried by lever h which is compounded for
this purpose, the said shaft o being driven by chain and chain wheels o' from the
bottom stud or shaft g which derives its motion by chain and chain wheels p from
the cross shaft f.
The hank carrying rollers are represented at 9 and are of any ordinary construc-
tion. Each hank carrying roller is provided with a square end ql as shewn at Fig. 3,

page_text: which is adapted to enter and engage with a square socket or opening n₁ (see Figs. 3
and 4) in the end of the short stud or shaft n¹ carrying the pinion n whereby when
notion is given to the pinion n and its shaft n', the bank carrying roller engaged
therewith will be revolved. The opposite ends of the bank carrying rollers
passed into open ended bearings r (see Fig. 5) on the other side of the carriage, this
inethod of mounting the hank carrying rollers in the carriage or frame facilitating
their application to, and removal from same.
are
From the carriage or frame m depend vertical arms or bars m³ central with each
pinion n and of the maximum depth to hold the largest size of hank which the
inachine may be constructed to take. These arins or bars m² are provided with open-
ended grooves m³ on their inner sides into which are adapted to enter and to adjust
themselves to any position intermediate of the length of the bars or arms the ends
of rollers 8 as shewn clearly in Figs. 3 and 6. The arms or bars m² are stayed at
their lower ends by horizontal longitudinal rails m' and each end arm at each side of
the carriage is provided with feet m5 so that the carriage or frane can be stood
upon the floor to charge and discharge the hanks of yarn.
The carriage or frame with the parts attached to saune is raised bodily into and
out of the vessel a by any suitable lifting mechanism and can be transferred by said
mechanism to any other vessel or series of vessels for scouring, bleaching and wash-
ing off purposes, there being no parts to disconnect or throw out of gear.
When the hanks have been placed around the top rollers q, and the loose bottom
rollers 8 said rollers are placed into the carriage or frame m, the rollers & being
passed into and falling down the grooves m³ to the full limit of the banks and keep-
ing same distended, while the taper square end q₁ and round ends or studs q² of
rollers are inserted in the bearings n and r.

As soon as the carriage or frame is
fully charged with hanks, it is lifted off the floor by a crane or other means and
lowered into the vessel a, until the upper cross shafts on said carriage enter and
engage with the bearings in the upper ends of the pendulous side levers h, h¹, h³, at
the same time the spur wheels n², n³ gear with each other and the whole of the parts
are in readiness for starting the machine. On the far ends of the cross shafts
mounted friction bowls or pulleys which on the carriage being lowered into posi-
tion as described engage with curved or radial surfaces or ways t secured to the side
of the vessel a, the arc of the curve being that described by the levers h, h¹, h²,
when oscillated upon their bottom fulcrums by the connecting rods j. As the
levers h, h¹, h² are oscillated, they carry the carriage or frame m bodily backwards
and forwards and also give to the said carriage a rising and falling motion to the
extent of the semicircular ways or surfaces which help to support and steady the
carriage.
are
The movement thus imparted to the carriage causes the hanks to be traversed
backwards and forwards through the liquor in the vessel and also to rise and fall
therein, whereby the liquor is kept in a constant state of agitation and the hanks
more fully and completely exposed to the action thereof. The constant rotation of
the hanks by the rollers q ensures the constant change of position of each individual
hank and brings every portion of it equally into the liquor.
The mechanism herein shewn and described may be applied to new cisterns or to
any existing cisterns.
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 :-
1. In machinery for dyeing, scouring and bleaching hanks or skeins of yarn, the
means and methods herein shewn and described for imparting to hanks a vertical
reciprocatory motion in addition to a rotary motion as herein shewn and described.
2. In machines for dyeing, scouring, and bleaching hanks or skeins of yarn, the
combination therewith of a curved surface such as t for the purpose of imparting an
up and down motion to the hanks in the liquor.
