Application filed March 3, 1911.

To alt/whom #may concern.' i

Be it known that I, BERTRAND S. SUM- Mnns, a citizen of the United States, residing at Port Huron, inthe county of St. Clair and State of Michigan, have invented certain new and useful Improvements. in Dyeing Apparatus, of which the following is a specification.

My invention relates more particularly to dyeing vats. and means for securing a'proper circulation and supply of liquid thereto. In apparatus ofi this character it is essential that the dye be evenly distributed throughout the material to be treated and that fresh bodies. of: dye be continually brought into contact with the material treated in order to get: an even hue. of the required depth. Various apparatus has been devised. for this purpose but none of it completely meets the requirementsof the art.

In my apparatus the liquid is caused to surge through the material treated in a vertical direction and at the same time to give a slight lateral motion or displacement thereof. And I further provide means for continuously drawing off the liquid-from the bottom of the vat and supplying itagain at the top thereof, either with or without treatment of the liquid or additions thereto during its absence from the vat.

The accompanying drawing discloses. a

preferred form of my apparatus, though itwill be apparent from an understanding thereof, in connection with the detailed description which follows, that various modifications may be made in the apparatus without departing from the scope of my invention.

The view illustrates the apparatus in a diagrammatic way in side elevation with certain parts shown in section.

In the particular embodiment shown A refers to a tank which is divided by a partition B into a dyeing vat C and a chamber D into which the liquid from the dyeing vat may be partially withdrawn, the partition B being cut away near the bottom as at E to provide a passage between the two compartments of the tank. The vat C is provided with a perforated false bottom G which extends across the same at a point above the connection between the compartments D and C and the compartment C is further provided with a perforated cover plate H between which and the false bottom G the material to be treated is confined.

Cl is a heatingcoil.

Vithin the compartment D a plunger J is arranged to reciprocate loosely and linked by a connecting rod K to an eccentric pin L on a disk M which may be rotated for the purpose of reciprocating the plunger. As shown, the chamber D and plunger are rectangular, but it will be evident that other for-ms might be adopted or the chamber I) formed separate from the vat, in which case it might be cylindrical and if desired a diaphra m be substituted for the plunger, such modication being obvious equivalents of the construction shown.

A System of piping leads from the bottom ofthe tank A through the pump C, shown diagrammatically as of a rotary type, to a point above the tank, the system including pipe connections I?, 2, R, S and T. The last named section is provided at its end with a swiveled section U, which is adapted to be swung from the full line position above the vat C over to the dotted line position above the compartment D- so that the liquid may be discharged ldirectly into either the.one compartment or the other. A drain pipe X is connected to the pipe section P and suitable valves V, V and V2 are interposed in the positions shown for regulating the flow through the various pipes. A storage tank Y is also connected by pipe section Z leading from its bottom with the circulating pipe system as shown, a suitable valve V3 being provided to control the communication, and a return pipe a provided with a valve VA1 leads from t-he discharge side of the pump to a point above the storage tank Y.

In normal operation the liquid dye is placed in the storage tank Y, the swivel pipe section U swung to the dotted line position over the compartment D, the valves V3 and V2 opened and the remaining valves closed. The pump is then started in operation and the dye discharged into the compartment l). By discharging the dye into this compartment rather than directly into the compartment C the un'evenness which would result from the discharge of the fresh body of dye in one location in a circumscribed area upon thematerial being dyed is avoided. After the dye has been discharged fl'oni the storage tank Y in sufcient quantity into tank A the valve V is opened and the valve V3 closed, Whereupon in the continued. operation of the pump the liquid is withdrawn from the bottom of the tank and discharged into the top of the vat C, the swivel section U having been swung over into suitable position for this purpose. If at any time it be de sired to withdraw the liquid from the vat the valve V2 may be closed and valve V4 opened, when the continued operation of the pump will discharge the liquid into the storage reservoir Y. I have found that the operation of the plunger J gives a surging motion to the liquid in the vat C causing itl to rise and fall therein through the perforations in the false bottom G and at the same time giving to the material being treated a horizontal motion or jogging, the combined action being particularly effective in securing penetration of the dye to all parts of the material, and this action combined with the continuous circulation of the liquid through the pipe system above described secures great uniformity and quickness of action of the dye.

wWhat I claim is:

l. In an apparatus for subjecting material to the action of a liquid, a tank for dyeing substances, means connected with said tank for imparting an up and down motion to the liquid contained therein and for pro ducing a. lateral motion of the contained material, and means for circulating the liquor contained in the tank.

2. In apparatus for subjecting material to the action of a liquid, a dye vat, means for causing a surging motion of the liquid therein and other means for continuously withdrawing liquid from one part of the vat and supplying it to another part thereof.

3. In apparatus for subjecting material to the action of a liquid, a tank, a partition dividing the tank into a vat and a plunger chamber, there being connection between the vat and the plunger chamber, a plunger in the plunger chamber and means for withdrawing the liquid from the botto-m of the tank and supplying it to the top thereof.

4. In apparatus for subjecting material to the action of a liquid, the combination of a. tank having a partition therein dividing it into a dye vat and a plunger chamber, a plunger working in the plunger chamber, a system of pipes and a pumpfor withdrawing liquid from the bottom of the tank and discharging it into the top thereof, a storage tank connected to the system on the suction side ofthe pump and a connection from the exhaust side of the pump to the storage tank for restoring liquid thereto.

5. In an apparatus for subjecting material to the action of a liquid, a vat having a substantially vertical -wall at one end, an opening at the other end, and means connected with the opening for forcing a current of liquid back and forth througl'i said opening, and a perforated bottom located above the opening and spaced from the bottom at its juncture with said Wall whereby the rebound of the liquid from said wall will produce a to and fro motion of the material being treated.
