GUSTAVE A. FRIEDRIOHS, OF VVOONSOOKET` RHODE ISLAND; ASSIGNOR OF ONE-HALFTO CHARLES A. PROULX, OF VVOONSOOKET, RHODE ISLAND.-

DYEING APPARATUS.

Patented Dec. 12, 1905.

To a/ZZ whom t may concern:

Be it known that I, GUsTAvE A. FRIED- RICHs, a subject of the King of Belgium, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Dyeing Apparatus, of which the following is a specification.

My invention pertains to dyeing apparatus; and it contemplates the provision of a simple and eflicient apparatus designed more especially for expeditiously dyeing textile rovings and adapted to be used to advantage in dyeing other materials.

The invention will bek fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure l is a view, partly in vertical section and partly in side elevation, of so vmuch of a dyeing apparatus as is necessary to illustrate my invention. Fig. 2 is a perspective view with parts broken away, illustrating the holder for material to be dyed and the perforated tube for spraying dye into such material; and Fig. 3 is a perspective view of the cover for @the said material-holder and spraying-tube removed.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which- A is a vat, which is preferably of the open type.

Bis a spraying-tube extending upwardly` from the bottom of the vat and having perforations throughout its length-i. c., from a point adjacent to the bottom of the vat to its upper end.

O is a holder for textile rovings or other material to be dyed, which is removably arranged on the bottom of the vat and around the tube B and D is the cover for closing the upper end of the material holder and the perforations in the upper portion of the sprayingtube.

My invention contemplates the use in the vat A of a' number of spraying-tubes B, material-holders C,`and covers D, relatively arranged as shown and distributed throughout the area of the vat; but as the spraying-tubes B and their complementary material-holders C and covers D are identical in construction I have deemed it suflicient to illustrate but one of each.

As shown in the drawings, the materialholder C is cylindrical in form and comprises an annular base a, an annular head b, upright rods c, grouped about the vertical center of the holder and comiecting the base a and the head b, and aside wall d, ofwire-gauze or other reticulated material, connected to the base and the head and arrangedkwithin the series of rods c, whereby it is prevented from bulging when the holder is charged with textile rovings or other material to be dyed. The said holder O is designed to be filled with rovings or other material to be dyed while it is positioned in the vat, as illustrated g but its being removable Lfrom the vat is advantageous, inasmuch as when it is removed it may be cleared of collected sediment with great facility.

'The cover D comprises a central upright tubular portion e, which is of a size to snugly receive the spraying-tube B, and a flange f, which extends outwardly from and surrounds the lower end of the tubular portion c, and is of a diameter to snugly occupy the interior of the cylindrical wall d of the material-holder C. By virtue of the said cover D being construoted as stated and arranged as shown in Fig. 1, relative to the spraying-tube B and the material-holder C it will be observed that the said cover may be adjusted vertically on the tube and in the holder, so as to adapt the cover to the quantity of material in the holder It will also be observed that as the cover is 'moved downwardly to carry its flange f against the material in the holder its tubular portion e sliding over the spraying-tube will serve as a stop to the dyeliquor and compel the same to pass through the material to be dyed instead of passing up and out of the tube at a point above such material, as it would do were no cover provided. This assured passage of the dye liquor through the material to be dyed obviously contributes to the thoroughness of the dyeing operation and Amaterially accelerates the same.

TOO

G is a pipe connecting the eduction-oriice L ofthe pump and the lower end of the spraying-tube B and equipped with a valve 7c.

H is a pipe connecting the portion of the pipe G between the valve k and the tube B with the portion of the pipe F between the valve h and the induction-oriiice g of the pump and equipped with a valve Z and I a pipe connecting the portion of the pipe G between the valve c and the eduction-oriiice i of the pump with the portion of the pipe F between the valve h and the vat A and equipped with a valve m.

With the valves handkopen and the valves l and m closed it will be observed that the dye liquor will pass Jfrom the eduction-orifice of the pump through the pipe G, the tube B, the material to be dyed, the vat and the pipe F back to the induction-orifice g of the pump, this with a view of assisting in or accelerating the thorough dyeing of the material. When, however, the valves 7c and 7L are closed and the valves Z and m are open, the dye liquor will take the opposite course relative to the vat A, the material to be dyed, and the tube -fi. e., will pass from the eduction-ori- :tice of the pump through the pipes G,'I, and F into the vat and after percolating through the material to be dyed will pass through the tube B and the pipes G, H, and F back to the induction-oriiice of the pump, all as indicated by arrows.

It will be gathered Jfrom the foregoing that in addition to the practical advantages which I have hereinbefore ascribed to my novel ap-.

paratus the same is inexpensive in construction, is easily maintained in properv working condition,` and embodies no delicate arts such as are liable to get out of order aflter a short period of use.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an apparatus for dyeing textile rovings and other material, the combination of a vat, a spray-tube extending upwardly in the vat and adapted to be connected with a source of dye-liquor supply, a inaterial-holder surrounding the spray-tube, within the vat,

and having passages in its side wall, and a cover comprising a tubular portion receiving and vertically movable on the upper portion of the spray-tube and closed at its upper end and a flange surrounding the lower end of said tubular portion and snugly occupying and movable vertically in the material-holder.

2. In an apparatus for dyeing textile rovings and other material, the combination of a vat, a spray-tube disposed in the vat, a material-holder arranged in the vat around the spray-tube and having passages in its side wall, a pump, a conduit intermediate the vat and the induction-oriiice of the pump and having a valve 7L at an intermediate point of its length, a conduit intermediate the lower end of the spray-tube and the eduction-oriiice of the pump and provided with a valve 7c, a valved conduit connecting the portion of the first-mentioned conduit between the pump and the valve h with the portion of the second-mentioned conduit between the spraytube and the valve c, and a second valved conduit connecting the portion of the iirstmentioned conduit between the vat and the valve h with the portion of the second-mentioned conduit between the valve k and lthe pump.

3. In an apparatus for dyeing textile rovings and other material, the combination of a vat, a spray-tube extending upwardly in the vat and adapted to be connected with a source of dye-liquor supply, a material-holder removably arranged in the vat, around the spray-tube, and having passages in its side wall, and a cover comprising a tubular portion closed at its upper end and snugly receiving and movable vertically on the upper portion of the spray-tube and a ilange sure rounding the lower end of said tubular pore tion and snugly occupying and movable vertically in the material-holder.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
