JAMES HENRY ASHWELL, OF NEW BASFORD, ENGLAND.

MACHINE FOR DYEING- HANKS.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed October 12, 1907. Serial No. 397,036.

To all whom it may concern:

Be it known that I, JAMES HENRY Asrr WELL, a subject of the King of Great Britain, and resident of Radford Road, New Basford, Nottingham, England, dyer and bleacher, have invented new and useful Improvements in Machinery for Dyeing Hanks, of which the following is a specification.

A machine for dyeing hanks embodying the present invention comprises a tank or cistern containing the dye liquor. In connection with this vessel are arranged a pair of endless chains traveling partly in and partly out of the liquor. These chains carry the dye sticks whereon the hanks to be dyed are hung. The dye sticks are inserted at suitable intervals into the links of the chains in such a manner that they are detachable when required but will not come out of position so long as they are desired to remain. To this end one of the chains is provided with sockets into which the sticks may be thrust endwise and the other chain has sockets into which the ends of the sticks are thrust transversely. The sockets are so contrived that when the sticks are inserted therein and partly rotated they will remain until purposely removed. The chains are mounted on sprocket wheels keyed upon shafts which are supported on a movable frame. Means are provided for raising and lowering the said frame and the chains and the dye sticks therewith when required. One of the sprocket wheel shafts is driven by any suitable means from any convenient source of power.

The hanks are hung on the sticks before the latter are placed in the sockets in the endless chains and while the framing which supports the chains is in its raised position. When the dye sticks are loaded the framing is lowered until the lower portion of the chains is submerged 5 or 6 inches in the dye liquor. The chains are then driven and the hanks are drawn round and round through the liquor until the operation is complete.

In the accompanying drawings, Figure 1 represents the subject of this invention in side elevation, Fig. 2 is a plan view of the chain of dyeing sticks and frame which supports the same, Fig. 3 is an end view, and Figs. 4 and 5 show detached links of the endless chains which support the dyeing sticks.

a is the bark or cistern containing the dye liquor.

b is a frame supported by links 0 pendent from cords cl which are wound on drums eon the overhead shaft f. This shaft f has also the drum 9 for winding up the cord h of the balance weight 2' which cord passes over the pulley j.

7c is a grooved pulley and Z an endless cord thereon by means of which the shaft f may be rotated in either direction. The frame 6 carries bearings for the shafts m n and 0 upon which are mounted wheels 79 p, g Q and r r for the endless chains 8 and t. One of these chains is built up of links a (see Fig. l) and the other of links '0 (see Fig.

The hanks to be dyed are strung on sticks to having rounded and D shaped ends. The rounded ends are inserted in the round holes of the links a while the opposite D shaped ends are inserted in the clips of the links 4). l/Vhen thus inserted and rotated a quarter turn the sticks will remain until intentionally removed. The sticks with the hanks thereon are placed in position in the chains when the frame is in the raised position of Figs. 1 and 3 in which position the chains may be made to advance by means of the hand wheel 00 keyed on the shaft m. When the sticks are loaded the frame 7) is lowered by turning the shaft f in the proper direction until the base of the triangular path of the chain is submerged in the dye liquor to the desired extent. (See dotted position of Fig. 1.) In this position the spur wheel y on the shaft engages with the pinion 2 indicated by dotted and drawn lines respectively in Figs. 1 and 3 which pinion is driven in any convenient way. By means of this gearing the chain of dye sticks is caused to travel and draw the hanks carried thereby through the liquor and around the whole triangular path followed by the chain. In this way the operation of hand dipping is closely imitated and work of equal quality produced. At the same time the output of the machine is far greater than that of hand labor.

1 are guide rods fitted to the frame I), which guide rods slide in guide pillars 2 thereby steadying the frame in its upward and downward movements.

When the frame is raised ready access to the bark at for cleaning the same or renewing the dye liquor is provided.

That I claim as my invention and desire to secure by Letters Patent is 1. An apparatus for dyeing hanks, comprising a tank, a frame located above the tank, means for raising and lowering the frame, a pair of continuous chains carried by the frame, means for causing said chains to travel in a triangular path and dyeing sticks detachably arranged in the chains.

2. An apparatus for dyeing hanks, comprising a tank, a frame located above the tank, a counterweight and mechanism for raising and lowering the frame, a pair of continuous chains carried by the frame, dye- 9o9,51a a ing sticks detachably arranged in the chains, means for automatically locking said sticks in osition and means for causing said chains to travel in a triangular path.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
