JOHN C. EVENDEN AND CHARLES FROHLICH, OF AMSTERDAM, NEW YORK.

DYEING APPARATUS.

Application filed November 9, 1908.

Specification of Letters Patent.

1'0 all whom it may concern:

Be it known that we, JOHN C. EVENDEN and CHARLES FRoHLIoH, citizens of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Dyeing Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for dyeing, scouring, bleaching or otherwise treating fibrous material, and it more particularly relates to an improvement in apparatus of this character adapted for dyeing materials such as raw cotton and wool, hosiery, knit underwear and cops.

One of the objects of the invention is to provide apparatus such. that the material treated will be uniformly saturated or impregnated with the dye.

Another object is to provide dyeing apparatus whereby the material to be dyed as well as the dye liquor may be easily and quickly handled.

Another object is to provide mechanism whereby the dye liquid may be utilized repeatedly if desired, and which ail'ords improved facilities for maintaining or changing the temperature of the dye liquid.

' A further object is to provide a machine which will occupy a minimum amount of space and which may be operated with little care or attention on the part of the operator.

Other objects will be in part obvious, and in part pointed out herewith.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims:

In the accompanying drawings wherein is illustrated one of the various possible embodiments of our invention, Figure 1 is a central longitudinal section of a machine constructed in accordance therewith; Fig.

.2 is a horizontal sectional view taken substantially on the line 2-2 Fig. 1.

Similar reference characters refer to similar parts throughout both views of the drawings.

Referring now to the drawings, wherein we have shown our improved machine adapted for dyeing yarn in cop form, 1 denotes a rectangular'tank mounted upon suitable supports 2 which may rest upon the ground or floor. This tank, which is adapted to hold the dye liquor and the material to be dyed, is provided, in the present instance, with openings as at 3 and 4, respectively, in its upper wall near either end thereof, said openings being adapted to be closed by cover plates 5 and 6, respectively. Cover plates 5 and 6 are fastened tightly in place as by means of bolts and nuts 7 so as to provide against the escape of the dye liquor during the operation of the machine.

Located within the tank 1 directly beneath each of openings 3 and 4 are perforated receptacles 8 and 9, respectively, said receptacles being lightly spaced from the end walls 10 of the dye tank as by means of spacing members 11, said spacing members and the bars 11 forming suitable compartments in which the receptacles may be set.

12 denotes a closed tank from whichthe dye liquor is supplied to the dye tank through valved conduits 13 which lead into said dye tank at points intermediate said receptacles. The su ply tank is also connected with the end walls 10 of the dye tank by means of conduits 14 and 15, suitably valved, as at 16, which are branched to enter the upper and lower portions of the tank at the ends thereof. The dye liquor may be maintained at the desired temperature by means of a steam conduit 17 located in supply tank 12, and the dye liquor may be supplied to tank 12 through a conduit 18 leading into the upper portion thereof. A drain conduit is provided at 19 leading from the bottom wall of the supply tank and a relief or safety valve is provided at 20 in the upper wall of the supply tank.

A receptacle 21 is provided exteriorly of the dye tank and supported thereon as by means of brackets 22, said receptacle being provided with a removable cover portion 23. This receptacle is adapted for holding a sample of the material to be dyed, and is connected with the dye tank at points adjacent receptacles S and 9 by means of conduits 24 and 25, respectively.

A. piston 26 is located within the dye tank 1 intermediate receptacles 8 and 9. Piston 26 in the present instance com-prises end plates 27 and 28, respectively, of rectangular shape to conform to the interior conformation of the dye tank, spring pressed blocks as at 29, being provided for preventing the passage of the dye liquor between the piston and the walls of the tank. Bars 30 and 81 provide a rigidaconnection for plates 27 and 28, respectively, said bars being provided with teeth as at 31, with which cooperates a mutilated gear 32 mounted upon a shaft 83 adapted to be driven from a suitable source of power.

It will be understood that by means of the construction last above described a rotation of gear Wheel 32 will operate to reciprocate the piston in the dye tank. It will also be understood that mechanism other than mutilated gear construction may be employed for reciprocating the piston.

Conduits 34 which will lead from the bottom of the dye tank may be utilized for draining the tank of the spent dye liquor or for conducting the same to a suitable receptacle when it is desired to utilize the same for another dyeing operation.

Having thus described the construction of this embodimentof our invention, the operation thereof may now be understood.

The material to be dyed is placed in the receptacles 8 and 9 which, for convenience, are made removable, enabling them to be lifted from the dye tank for the purpose of loading or unloading. The receptacles are then inserted in their compartments in the end portions of the dye tank and said tank is then closed by means of the cover plates 5 and 6. At this point it may be noted that while we haveshown the dye tank open at the top, such openings may be formed in the side walls if desired, suitable closures being provided for rendering the tank water tight. After the dye liquor has been heated to the desired degree in the supply tank 12 it may be discharged into the spaces bet-ween the piston and the receptacles 8 and 9, re spectively, by opening the valves in the condui'ts 13. The apparatus is then ready for operation. It will be understood, of course, that tank 1 will be kept filled with the dye liquor, which may be discharged therein by gravity or forced therein by means of suit able pumps. During the reciprocation of piston 26 the dye liquor will be forced alternately in opposite directions through the material in the receptacles 8 and 9, the dye liquor, after passing through the receptacles, flowing into the supply tank 12 through the conduits l4 and 15. A similar circulation of the dye liquor will take place through the sample receptacle 21 by means of the conduits 24 and 25. In other Words, the dye liquor will circulate alternately in opposite directions through the entire apparatus, the desired temperature thereof being at all times maintained by means of the steam conduit 17. l/Vhen it is desired to unload the machine, the valves and conduits 13 are closed and the dye tank drained through the conduits 34. The cover portions are then unlocked and the receptacle-s S and 9 removed from the storage tank and unloaded, when the dyeing operation may be repeated upon fresh material. It will, accordingly, be seen that we have provided apparatus especially well adapted to attain, among others, all the ends and objects above pointed out, in an extremely simple, yet efficient manner. The locating of the piston within the dye tank effects an economy in the use of space, and the provision of the sample box exteriorly of the dye tank results in a great saving of time, since it permits the material being treated to be examined without making it necessary to suspend the operation of the machine while the dye tank is being opened for inspection.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
