Leicester, England, assignors to Mellor Bromley & Co. Limited, trading as Samuel Pegg & Son, Leicester, England Application December 26, 1947, Serial No. 793,802 In Great Britain May 11, 1946 Section 1, Public Law 690, August s, 1946 Patentexpires May 11, 1966 This invention relate to machines for treatin textile goods, such as yarns, hosiery and other articles or pieces, hereinafter for brevity termed -goods, in loose form, and comprises an improvement the object of which is to attain certain advantages as will be hereinafter set forth;

A specific example of theinvention applied to a dyeing machine suitable for dyeing, say, loose wool will now be described with reference to the accompanying purely diagrammatic drawings, wherein, 5fFigllIfel is a transverse sectional view of the said machine, I

Figure 2 is a longitudinal sectional view of the same taken" onthe li'ne II II of Figurel, and Figure 3 is a plan view of the casing of the machine, with the top-perforated plates removed and portions of the false 'bottom' broken away toexpose the propeller tunnel.

Like parts are designated by similar reference characters throughout the drawings. j

A I The machine illustrated-includes a wooden casing -l withinwhich is fitted a tank or; vat 2 of sheet metal having a rounded bottom 3. Fitted in; this tank or vat ,-is a removable perforated plate 4, constituting a false bottom, spaced from therounded bottom 3. Thetank or vat 2 is divided-into two equal compartments A and B by a vertical partition 5, of'sheet metal extending from one side or end of the tank or vat to the opposite side. The partition 5 is attached to the false bottom 4 and terminates below the rim of the tank or vat 2. Located in the spaces (see Figure 1) between the false bottom 4 and the actual bottom 3 of the tank or vat, directly under the partition 5, is a propeller tunnel 6 of sheet metal with openings 1 in one side and somewhat shorter openings 8 in the opposite side. Thus, the lower part of the tank or vat 2 is divided into sections and D corresponding with the superposed compartments A and B respectively, and

the aforesaid openings in the respective sides of the tunnel 6 are disposed towards the co-adjacent sections. Conveniently, and as shown in Figures 2 and 3, there ar four opening 8 in the one side and two longer openings I, each intermediate of two of the said openings 8, in the opposite side of the tunnel 6. As shown in Figure 2, a propeller shaft 9 mounted in bearings l0 and fitted with four propellers H, R. H., L. H.,R,. H. and L. H., is mounted in the tunnel 6 so that the arrangement, starting from the left hand of the tunnel is as follows: 1st opening; R. H. propeller; 2nd opening; LQH. propeller; 3rd and 4th openings; R. H. propeller; th opening; L. H. pro- 5 Claims (cits-18v) peller, and finally the 6th opening. This particular arrangement may, however, be varied by reversing the propellers. The openings 1 and 8 are preferably of elliptical or equivalent horizontally elongated form. Hingedly attached to the partition 5 on opposite sides thereof ad: jacent to the top edge, are perforated plates I2 serving as closures for the compartments A and B, andstirrups such as l3 (Figure 1) are removably" mounted on appropriate parts of the machine so as'to extend into the tank or vat 2 adjacent to the free ends of the hinged plates l2 to hold the latter down when in the horizontal position, the hinges 14 being of such a character as -to hold the plates horizontally and permit of them" being lifted. The stirrups I3 are conveniently U-shaped' and each is clamped in position by means of an eye IS with which one leg of the stirrup is engaged, and a handle [6- or wing screw in the eye. Lifting hoops, hooks or eyes such as I! are attached to the partition 5 at the upper edge thereof as seen in Figures 1 and 2.

The machine is preferably electrically motorized, and in such case the motor [8 is mounted at one side or end of the casing l within a cover l9,

. and drives the propeller shaft 9 by means of belt or other gear 20 (Figure 2).

I Considering the machine as built with a minimum of two compartments since what applies to one pair also applies to more than one pair, e. g. two pairs if there are four compartments, the modus operandi is as follows:

With the top perforated plates I2 lifted, the loose wool or other goods to be treated are deposited-in equal amounts-in each of the compartments A and B. The compartments are then covered by lowering the perforated plates l2, and the tank or vat 2 is supplied with the necessary liquid. The motor I8 is then started to circulate the liquid, the direction of circulation being upwards through the compartment B over the perforated top plates I2, downwards through the other compartment A, and through the correof circulation is correspondingly changed. For this purpose, in a motorized machine, automatic reversing gear is fitted. It is considered that with the improved machine the goods will be subjected to uniform conditions during the operation.

It will be appreciated that during the whole of the process there will always be suction in either one compartment or the other. jm consequence, very little effort is required to hold the false bottom 4 and its load in the machine. In this connection the said bottom may, as shown in Figure 1, rest upon supports 2| fixed in the tank or vat 2.

When the treatment is complete the partition 5 and false bottom 4, which in effect are in one piece, are lifted bodily out of the tank or vat 2,, bringing the treated goods with them. The goods and in particular dyed loose Wool forms compact cakes the size of the compartment, and can bev easily pushed off the false bottom into a truck or other convenient container for removal. I

An important feature of the improved machine i that the liquid when running in either direction must go through the goods to be treated thereby reducing to a minimum any turbulance of the liquid. It is considered therefore, that this machine will be ideal for vat colours and all colours where the elimination of air is an important factor.

The whole of the tank or vat above the false bottom provides available space for the goods to be treated, thus reducing floor space to the minimum.

What we claim then is:

1. A machine for treating textile goods with liquid comprising a tank adapted to receive the goods to be treated, a perforated plate disposed within and spaced from the bottom of the tank to provide a'false bottom therefor, 'at-least one partition extending upwardly from the said perforated plate to divide the interior of the tank into separate compartments, additional perforated plates on opposite sides of the said partition at a point above the first mentioned per foratedplate for providing lids for the compartments, means adjii'stably mounted on the tank and adapted to cooperate with said second mentioned perforated. plates to maintain said plates in a substantially horizontal position,'a tunnel under said first menti'ohed perforated plate directly below the said partition and being provided with lateral openings in opposite sides thereof, said tunnel dividing thespa'ce between the first mentioned perforated plate and the bottom of the tank into sections corresponding with the said compartments, and the section being in communication with the compartments through said lateral openings, a rotary shaft located within the tunnel, propellers on said shaft and disposed adjacent the said lateral openings, and means for imparting movem'entto said rotary shaft.

2. A machine as claimed in claim 1 wherein the said additional perforated plates are hingedly connected to the partition.

3. Amach'ine as claimed in claim 1 wherein the saidkpartition i removably mounted within the tan '4.
