Improvements in Yarn Dyeing Machines.
I, JOHN GEORGE HASLAM, of Lehigh Avenue and Howard Street, Philadelphia,
in the County of Philadelphia, State of Pennsylvania, United States of America,
Dyer, do hereby declare the nature of my 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 more particularly relates to dyeing machines in which a yarn
carrying frame is suspended in a dye vat by lifting devices (by which it may be
raised from the vat or inserted therein), and is combined with mechanism for
reciprocating it in the dye liquor for the purpose of subjecting the yarn to the
proper action of the liquor.
With the apparatus shown in the Patent to Wostenholme No. 2060, dated
5th February, 1889, it is necessary to disconnect the yarn frame from the lifting
devices to permit it to be reciprocated in the liquor. In my improved apparatus
this disconnection is unnecessary as the yarn frame is so supported by the lifting
devices that it may be reciprocated therein without disconnection.
My invention also includes improvements in the devices for reciprocating the
yarn frame to move the yarn through the liquor, and embraces automatic locking
devices upon the reciprocating arms or levers by which the yarn frame may be
automatically locked in the arms or levers, when it is lowered into the vat.
Another improvement relates to the construction of the yaro frame, and to
supports for the yarn sticks and embraces improved devices for adjusting the
supports for the yarn sticks, to bring the sets of sticks nearer together or further
apart to suit the size of the skeins.
In the Wostenholme Patent No. 2060, dated 5th February, 1889, upon which the
present invention is an improvement, the adjustment of the yarn sticks is accom-
plished by the movement of the supports for the lower set of sticks. The
adjustment can consequently be made only when the yarn carrying frame is lifted
from the liquor. By my improved construction, I accomplish the adjustment
through the supports for the upper set of yarn sticks, so that it
may be accomplished
from the top of the yarn frame, and while the frame is lowered in the vat and the
yarn submerged in the liquor.
Another feature of my invention consists of the employment of indicating devices,
by which the number of reciprocations that have been imparted to the yarn frame
is indicated, so that the attendant or operator is notified when the yarn has been
sufficiently worked in the liquor.
My invention also relates to other improvements of construction and arrangement
of parts which are hereinafter fully described and particularly set forth in the
claims.
I shall now refer to the drawings for the purpose of describing the construction
and mode of operation of my improved dyeing machine.
Fig. 1 is an end elevation of my improved dyeing machine;
Fig. 2 is a longitudinal vertical sectional view of the same on the line 1-2
of Fig. 1;
Fig. 3 is a transverse vertical sectional view of the same on the line 3-4 of
Fig. 2;
Fig. 4 is an horizontal sectional view on the line 5-6 of Fig. 1;
Fig. 5 is a plan view of the end of one of the levers which support and reciprocate

page_text: Fig. 6 is a side elevation of the same;
Fig. 7 is a vertical sectional view ou the line 7-8 of Fig. 2, showing the support
of the yarn carrying frame on an enlarged scale;
Fig. 8 is a detail view illustrating a modification of the devices for adjusting the
yarn sticks;
Fig. 9 is a detail view of one of the supports of the yarn sticks; and
Fig. 10 is a perspective view of the support of the yarn carrying frame.
A is the vat, which may be of any convenient shape and construction.
B is the yarn carrying frame preferably of a rectangular shape.
This yarn carrying frame is preferably constructed of the uprights B' connected
at the top and bottom by the end cross pieces B2, B³, and B³, B³. The lower cross
pieces B³, B³, I prefer to use as the supports for the lower set of yarn sticks.
B, B, are longitudinal rods connecting the lower cross pieces B³, B³.
D, D, are the supports for the upper set of yarn sticks carried upon the end
uprights B', B, and for purposes of adjustment, I prefer to make these supports D
movable upon the uprights B', B¹. For this purpose prefer to employ the
rods D', D', carried by the end pieces B¹, B', and extending up through the
longitudinal piece C, with adjusting nuts D' upon the ends of the rods D', D',
provided with internal screw threads, engaging the threaded ends d of the rods D'.
By this means it is apparent that the supports D, D, may be raised or lowered
upon the uprights B', B', and may thus be adjusted with reference to the lower
supports B3, B³, to suit the length of the skeins of yarn to be treated. The
supports D, D, may be connected with the rods D', D', by braces d', d¹, for the
purpose of more firmly supporting them.
E are the upper yarn sticks carried by the supports D, D, and F are the lower
yarn sticks carried by the supports B³, B. It will be seen that the adjustment of
the yarn sticks is accomplished from the top of the yarn frame by moving the
upper supports D, D, so that the adjustment may be accomplished without lifting
the frame from the vat; and through the upwardly extending rods carried by the
supports D, D, the adjustment may be made even when the frame is submerged in
the vat.
For the purpose of permitting the yarn sticks to be easily inserted in their
respective supports, and to be readily removed therefrom, I prefer to form each
support with a series of sockets e, open at their ends to permit a longitudinal
movement of the end of the yarn stick in the socket so that they may be easily
inserted and removed. E is a longitudinal locking bar carried by the
Eupports D, D, and B3, B³, extending over and closing the open ends of the
sockets e, and supported by supports f. To insert or remove the yarn sticks,
the locking bar E' is withdrawn when the sticks may be moved longitudinally to
free the ends from the sockets e, or to insert them therein. The locking bar E
when in place, locks the ends of the yarn sticks in their sockets. To prevent the
skeins adjacent to the ends of the sticks becoming entangled in the sockets
the
sockets may be provided with a projecting guard e¹.
e,
For raising or lowering the yarn carrying frame to immerse it in the dye liquor
and to lift it therefrom, I employ a cylinder G provided with a piston, which may
be operated by gas, air, steam, water, and is provided with a piston rod H, connected
with the yarn carrying frame B.
The cylinder G is connected as at g with the pipe I, J, through which the gas,
air, steam or water may be fed to the cylinder or discharged from it to raise and
lower the piston in the well known manner.
The supply and discharge of the water are controlled by the valve h. The
cylinder G may be suspended or suitably supported from the wall or ceiling, but to
permit the yarn carrying frame B to be moved away from the vat A, when it has
been lifted from it, I prefer to connect the cylinder G with a movable trolley or
carriage I running on a guide or track I, and to make a portion of the pipe I,
as J, flexible or jointed so as to permit the movement of the cylinder.

page_text: By this construction the sprocket wheel S may be adjusted to put the proper
tension upon the chain S' since the wheel S and pinion Q are carried by the
lever R, which may be adjusted through the bolt and slot connection with
the lever R'.
The levers M; M, may be vibrated in any other convenient manner.
By the
vibration of the levers M, M, the frame B is moved up and down in the liquor, to
subject the yarn to the action thereof, by moving it up and down in the liquor, and
by suspending the skeins more or less loosely upon the yarn sticks, as described
in the Patent of Wostenholme, 2060, dated 5th February, 1889, the skeins will
move away from contact with the sticks during the reciprocation, thus permitting
the liquor to penetrate all portions of the yarn equally, and rendering unnecessary
the turning of the yarn sticks, as is now generally practiced for the purpose of
shifting the yarn. In the machine herein described it is a simple matter to
properly support the skeins so as to permit this movement; by reason of the great
ease with which the yarn sticks may be adjusted through the adjusting nuts D².
A modified form of these devices for adjusting the yarn sticks is shown in Fig. 8.
In this construction in place of the rods D', the racks D³ are employed, operated
by a pinion D carried in a bracket d' of the end frame pieces B' and locked by a
dog d². By releasing the dog d³, the pinion D* may be turned to raise or lower
the frames D.
To indicate the number of reciprocations of the frame B in the liquor and show
when the yarn has been subjected sufficiently to the action of the dye liquor, I
employ a rotary ratchet disc T operated by a pawl t, through a lever T¹, and
link, from one of the levers M. The pawl t is carried by the pivoted lever T
which is in turn connected with the lever M through the link t¹, so that upon each
vibration of the arm M the pawl will turn the disc T the extent of one ratchet
tooth. A pawl is employed to prevent backward rotation of the dise T. The
disc T may be provided with a dial face and a stationary finger or index U may
be arranged adjacent to it, so as to indicate by the figure upon the dial under the
finger or index U the number of reciprocations that have been imparted to the
yarn carrying frame. This indicating device may be further provided with an
alarm V operated by a pin or projection upon the disc T, so that when the
disc has been turned a given distance, corresponding with the desired number
of reciprocations of the frame B, the pin or projection v will strike the alarm and
operate it, indicating to the operator that the yarn has been sufficiently treated,
when by shifting the friction clutch P, the further vibration of the arms M, M,
may be stopped, and the frame may be lifted from the vat by the lift G, and
may be removed and replaced by another frame with fresh yarn.
While I prefer the minor details of construction that have been shown, I do
not limit myself to thein, as it is apparent that they may be varied without
departing from the invention.
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 :-
First. The combination with the yarn frame and vat of the lifting devices herein
described.
Second. The combination of the reciprocating yarn frame with a support in
which the yarn frame may be reciprocated without disconnection.
Third. The support consisting of the frame K having the hinged or removable
member K'.
Fourth. A yarn frame having the supports for the upper set of yarn sticks
independently adjustable with reference to the supports for the lower sticks.
Fifth. The yarn stick supports having sockets e and adjacent extension e'.
Sixth. The rocking arms or levers M having the notched ends and weighted
locks N for automatically locking the trunnions of the yarn fame.

page_text: Seventh. The driving mechanism herein described for operating the rocking
arms or levers M.
Eighth. The yarn carrying frame constructed as described.
Ninth. The means for adjusting the supports for the upper set of yarn sticks.
