T 0 all whom it may concern Be it known that I, FnLicn FRANCESCO LARIVEI, a subject of the King of Italy, residing at Bath, in the Kingdom of England, have invented new and useful. Improvements in Machinery for Dyeing and Treating Textiles, of which the following is a specification.

This invention relates to improvements in machines for dyeing or otherwise treating hanks ofyarns, slubbing and other textiles, in which the material undergoes the desired treatment immersed in the liquor. The object of the invention is to provide an effective mechanical means which, besides causes the material to be raised off the sticks by sudden falling contact with the liquor, whereby acomplete uniformity of treatment is obtained. 7

According to the present invention a frame, suspended in a dye vat and carrying the hanks of fibre or the like either on sticks, rollers or in a closed perforated cage, and partly immersed in the liquor and partly out, is first mechanically reciprocated up and down, the

upward movement taking place at a different speed than the downward movement, and then the motion is changed so that the said frame or cage is longitudinally reciprocated to and fro in the vat, in contradistinction to such machines in which the hank carrying frame remains stationary immersed in the liquor, or is moved uniformly and 8111111]:

taneously in both vertical and horizontaldirections. I p

The mechanism for reciprocating the frame up and down may be combined with means to hoist the frame clear of the vat when it is desired to remove or replace'the sticks carrying the fibre.

The invention is more particularly described with reference to the accompanying drawings, in which Figure 1 is a plan view-of the device in one form; Fig.2 is a corresponding side elevation. V

A vat 1 of any usual form is mounted adjacent to the driving'mechanism supported on standards 2. .A frame 3 is suspended within the vat 1 by means of a rope 4 passing over pulleys 5. The frame 3 is recessed at its sides as at 6, to receive the sticks 7 adapted to carry the hanks offibre to be dyed or otherwise treated by the liquor in the vat 1. A rail 8 is adapted to lie over the depressions only.

6 to hold the sticks in position, and this rail 8 can be locked by'meansjof'finger-pieces 9 turning on pivots l0.

When the to and fro horiZonta-l'motion is desired, pinion l3is slid into gear with the fully toothed wheel''A and the frame is connected to a reciprocating connectingrod 11, by a detachable pin .12 passing through the bracket 13 on the frame 3 and said connecting'rod '11. Frame?) is first lifted to a certain level to. allow of the insertion of bearing rollers 14: on spindles 15" in bearings16 on the top of-the sides of the vat 1. A step 17 maybe'arranged' at the" side. of the vat 1 to allow of this operationbeing conveniently performed.

The bearingrollers 1 .1: support a 'longi- H tudinal cross rail'18 having lateral brackets 19 integral with it, adapted to be connectedto eyes 20-011 the frame 3by detachable pins 21 connected to shortchains 22-on the frame to prevent accidental loss. The frame 3 can furtherybe guided in its to and fro movement by means of bars-23% fastened detachup and down reciprocation of the frame 3,

the cord 4 is attached to the peripheryof pulley 28. 1.

The difference inflspeed of the vertically reciprocating frame when moving. up. and

down can be obtained .by meansof gears or drums of different diameter. In a preably by set screws 24 on theside of the vat ferred arrangement, however, the high speed is obtained in one direction by allowing the driving shaftto. rotate freely by reason ofthe weight of the frame connected to it, so that the yarn, at the fall of the frame, is

raised off the sticks-by the maximum resist ance of the liquor created.by.the..extreme velocity ofv the fall. shaft 36 mounted .inbearings ,;on frame 2, is continuously rotated in one direction On this shaft36, which .carriesa, worm wheel 38 driven by a worm 39 on a:

For this purpose the I shaft 40 having fast and loose pulleys 41, -12, are mounted gears MC and'32. The gear 32 is toothed on a limited length of its periphery only. It is obvious that if pinion 43 is kept out of gear, the shaft will rotate in one direction as long as pinion 31 engages with the toothed portion of a mutilated wheel 32 causing the rope f to coil itself on pulley 2S and thereby raise the frame 3; but as soon as the last tooth of the mutilated wheel disengages self from pinion 31, shaft 30 thus set free, will reverse under the weight of frame 3 and will thereby be lowered into the vat uncoiling the rope 4 from pulley 28 in its fall. When the toothed portion of the continuously rotating wheeliiil comes again to engage with pinion 31, frame 3 is again raised and fallsback into the vat in the same manner andthus the difierential up and downinotion will continue as long as desired. If required,

- means maybe provided to allow the guioing of frame 3 in vat 1' up and down, without later on interfering with the to and fro movement.

Should now it be desired to revert to the to ,and fro movement, the rope 4 is disconnected from the pulley 28, the pinion 4:3 is then slid. into gear with the fully toothed pinion l4: onshaft 3,6. The shaft 30 then rotates continuously in the same direction.

The rotation of shaft 30 is communicated to aparallel shaft 4:5 through pinion gearing 46, 1:? The shaft as. has a-hevel wheel 48 keyed to, it which drives the. bevel wheel 49 on shaft 50 which carries a disc 51 having a crank pin carrying the connecting rod 11,

reciprocating this, whereby the frame 8 is moved to and fro in the manner previously described.

When it is desired to remove the sticks 7 from the frame 3, or. remove frame 3 from the vat for any reason, the rope is connected to a pin on the periphery of pulley 29 and shaft 30 .is given a rotation so that the rope 4 is wound on pulley :29 and frame 3 is raised above the vat. Rails can then be slid in under the frame and this removed. To lower the frame rope l is first coiled by hand round the periphery of pulley in a direction opposite to that in whichthe shaft 30 rotates, and thus when the machine is set in motion, shaft 30 in its rotation uncoils rope 4:, whereby the frame 3 is lowered into the vat. The rails 18 are detachable from the frame 3 so that they canhe used with a number of frames.

It is obvious that a single driving mechanism as shown on the stand 2 can operate the movements of frames in anumher of vats, that is to say that for instance to obtain the up and down motion, a. rope or ropes 52 may pass along with or be connectedto the rope 4, to connect to the rails l8 of-tlie frame working in connection with vat. Again the vat'l may be subinto a number of compartments in each of which a frame 3 may be arranged simultaneously or separately operated from the d ng mechanism on the stand.

, T larly if the shaft 4-5 is run alonga combination of separate vats or subdivisions of one vat, the to and fro horizontal motion is easily obtained by connecting each vat or each subdivision of one vat to shaft 45 through similar arrangementsv of bevel wheels 48, 49, shaft 50, disc 51, and rod 11.
