DYEING-MACHINE.

Application filed March 25, 1921.

To all whom t may concern.' y

Be it known that I, JAMEs A. GRUNDY, citizen of the United States, Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Dyeing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to dyeing machines, applicable to the dyeing of yarns, and speciically to that known type of such machines which comprises an exterior container for the dye liquor and a dyeing vat, havin a perforated bottom, supported Within, an in spaced relation at its base and sides to the exterior container, both vat and tank being open at top, and where-in means, usually mechanical, are provided to produce an agitation and circulation of the dye liquor through the vat and in the .region of the yarns suspended therein; such machines operating in conjunction with a skein supporting frame, movable vertically, by appropriate hoisting means, into and out of the Vat.

My invention in a dyeing machine of the type stated has for its several objects to improve and simplify the structure by a novel construction and relative arrangement of some of the elements, including a rectangular contour of the exterior container and interior dye vat, constructing latter of even width but lesser length than the former so as to form circulation spaces at each long end, and so combining said elements in spaced relation thereto, not only at the respective ends but at base as before, to form complete circulatory channels both upwardly through and over the end walls of the dye vat, also mounting the inner or dye vat below the plane of the open top of the container, and by constructin the vertically movable skein-supporting fame in such manner that it lwill operate as a cover for the container when in operative position, in spaced relation to the top of the vat and thereby provide a closed passage way between the adjacent end walls of the vat and container for an inclosed circulation of the dye liquor; also the provisions of means forming part of the combined cover and frame whereby the yarn skeins may thereafter be separately moved on rotatable car- Speeifcation of Letters Patent.

riers in the frame during the dyeing operation; also the provision of perforated tubular means whereby compressed air may be used if desired in lieu of steam or of air under atmospheric pressure only, to produce a more effective initial agitation and, successively thereto a more perfect circulation of the dye liquor, from the spaces .between each channel end of the interior Vat and exterior container over the walls of and toward the center of the interior dye vat and through the perforated base wall there-- of whereby as a final result of the initial application of the dye' liquor to the yarn in manner and by the means aforesaid there will be produced a uniform shade of color throughout the skein; and finally, by an arrangement of the steam pipes for heating, relatively to the air` pipes for agitation and circulation, to connect and blow out the air pipes whereby any clogging of the latter by the dye stuffs used is readily removable.

To these ends my invention consists of the elements constructed and combined as hereinafter described, to effect the objects stated, the novel and characteristic features of the machine being as pointed out in the appended claims.

In the accompanying drawings illustrating the same:

Fi ure 1 is a longitudinal section through the yeing vat and its container tank; the yarn carrying frame; and above it a hoisting mechanism suspended over the vat, for operating the yarn carrying frame.

Fig. 2 is a horizontal section taken on line 2-2 of Fig. l-and looking in the direction of the arrows.

Fig. 3 is a sectional plan view taken on the line 3 3 of Fig. 2. y

Fig. 4 is a section through the air vents in the steam or air pipes.

Fig. 5 is a detail of one of the yarn carryin sticks and a crank for turning same.

eferring now to said drawings the eX- terior container for the dye liquor is shown as a rectangular tank consisting of end and side walls and base walls, each indicated at l0; is open at the top and adapted to be closed during the dyeing operation, by the top of the yarn frame operating as a remov- 13, the top edge of each of which is below the plane of the side walls of the container, and extend from and between the opposite long sides of the tank and in spaced relation to the opposite end walls thereof, the interior vat having a base wall 1l which extends between and is secured to the under edges of the partitioning

side walls

13, 13. and in spaced relation to the base of the container. This base wall 11 of the vat is perforated throughout substantially its entire surface, as at l1 (see Fig. 3). The rectangular elements are preferably somewhat greater in length than in width, for a reason to be presently stated. By this construction there is formed an interior vat and an exterior container with spaces between the basal walls of said elements and between the relatively narrow `ids of each` this construction being de- #.dely advantageous because it has been found difficult, indeed practically impossible, by any known means, to force a circulation of the dye liquor over the long side of -an interior vat, whereas to force it over the relatively narrow ends is comparatively easy, besides making it equally easy to reverse the direction of the circulation.

The

end walls

18, 13 of the interior or dye vat are of lesser height than the

end walls

10, 10 of the exterior container or tank, as shown in Fig. 1, in order that the circulation may be over these end walls of the vat, and toward the center thereof. The open top of the tank or container, as also of the interior vat is closed only when the machine is in operation, by means of the top portion of a yarn carrying frame 17 whic 1 forms a lid 1S the extreme ends 2O of which rest upon the end walls 10 of the tank; this lid forms part of the yarn-carrying frame 17, both of which are thereby adapted to be raised and loweredby any known hoistingr device such as indicated at 27 in Fig. `1. This construction enables the yarn-carrying frame, when lowered, to pass into the interior or dye vat, while the slightly inclined ends 20 of the movable cover 18 rest over without interfering with the channel spaces between the ends of the vat and tank and, by their inclination, tend to direct the course of the circulation 0f the dye liquor over the

walls

13, 13, of the vat.

That portion of the vertically movable cover which operates, in part, as the yarn carrying frame 17 has rotatably mounted therein a series of skein-holding members 21 which are squared, in cross section, as indicated in Fig. 2, and rounded at their ends to rotate in the side walls of the frame. as shown in said Fig. 2. The extreme ends of the yarn carrying members 21 are adapted to be rotated, such as by a crank 23 the end of which may be inserted in holes 22 in the end of the members 21 as a convenient means of removable attachment. These yarn-carrying members are preferably placed in staggered relation in the Yframe whereby they may be arranged closer together and thereby provide a greater yarn-supporting capacity in a given space, as by this arrangement the increased space required when turning the carriers 21, originally set square in horizontal parallelism, is materially lessened. The purpose of turning the carriers 21y is to allow that portion of the yarn skein (indicated at 26 in Fie. 1l which rests initially upon the square side of the carrier to then rest upon the angular edge of the carrier and be directly acted upon by the dye liquor, the skeins being supported on the carriers as indicated in dot and dash lines, 24 and 25, the former showing their position initially and the latter their position when the carriers are turned in their bearings.

Means for heating the dye liquor, preferably to a high temperature, approximately 212 F., are provided by a main steam supply pipe 30, controlled by a valve 31, connected with a manifold 32 and with a series of perforated pipes 332 extending adjacent to the base of the exterior tank or container (see Fig. l) and to the upper end of the steam supply pipe 30 and below the valve 31 therein is provided a by-pass 60 and a valve 61 governing it (see Fig. 2) whereby connection can be made, when desired, to the air piping system hereinafter described to blow out the latter and prevent any clogging of it.

It has been found in practice that mechanical and other known means to agitate and circulate the dyeing liquor are frequently inefficient for such purpose, in the respect that the yarn suspended at the center and at or near the opposite ends of the dye vat will not be fully and evenly reached by the dyeing liquor, nor at its initial strength in the beginning of the operation, and hence the yarn frequently takes on a sha-de somewhat lighter in parts than at other parts; which is obviously due to slow and inefficient initial agitation of the dye liquor at the beginning of the operation and in part to ineffective means to effect the successive circulation of the dyeing liquor throughout the tank in the region of the suspended yarns, and it is equally obvious that the quality and value of theA dyed product is injuriously affected by a lack of uniformity of color shade effected by such method and means of dyeing it.

Means to employ fluid pressure, prefer ably compressed air, to agitate the dye liquor in the region of the suspended yarns at the beginning and conclusion of the dyeing operation, and to intermediately set up a circulation of the dye-liquor at each end, successively` of the combined tank and vat and then in reversed order, over the end walls of the vat toward the center thereof,

as a system of piping, described as follows:

A main air supply pipe 40, controlled by a valve`41, connects with a series of perforated pipes 42 arranged horizontally within the tank, just above the steam pipes 33 and, of course, below the perforated base of "the interior dye vat. These pipes 42 are perforated to discharge laterally into the compartment 16`which is formed by the spaced relation between the perforated base of the vat and the bottom of the container. These perforated pipes 42 are disposed transversely of the length of the vat, and connect with a supply pipe 44 arranged at right angles thereto and which connects the series of pipes 42 with the main air supply pipe 40. A valve 45 controls the supply pipe 44.r Two

similar air pipes

46 and 50, are respectively arranged inand near the base of the

compartments

14 and 15, which are formed by the spaced relation between the ends of the vat and tank. These pipes are perforated to discharge upwardly. The air ipe 4'6 is connected With and supplied) by pipe 48, which is controlled by valve 49. The other similar air pipe 50 is connected with and supplied by pipe 52 which is controlled by valve 53.

The remaining novel feature of my device is as follows: It sometimes happens Athat the ingredients used in the dyestuff mixture used in making up the dye liquor will tend to clog the openings 43-47 and 51 in the air pipes 42-46 and 50, and the air is of insufficient force to fully remove these obstructions and open these perforations immediately it is applied. To overcome this objection I employ a tubular connection 60 leading from the main steam supply pipe 30 to the main air supply pipe 40 by tapping said pipes below the respective control valves 31 and 41. Interposed between these two pipes I locate a control valve 61. When it is desired to open the clogged air pipes I close the valve 4l thereby shutting off all air supply and

open valves

31 and 61 thus establishing steam' communication with the air supply system and by opening valves 45-49 and 53 allow steam pressure to flow freely therethrou h, thereby softening and blowing all clogging substances from the perforations.

The operation of the device other than as already explained, is as follows: The dye liquor is placed in the tank 10 and brought to a boiling heat by means of steam which is admitted through main steam supply pipe 30, controlled by valve 31,v carried to a` manifold 32, and thence to the erforated pipes 33 through which it is A equally to the liquor in the basal compartment 16 and thence dischargedupwardly through the openings 11a in the perforated istributed base 11 of the vat, to the liquor therein, wherein the yarn-carrying frame has been previously lowered, its inclined covering ends 19 and 20 resting on the end walls of the exterior container in spaced relation to the top of the walls of the interior vat, and

hence providing a removable cover of closed circulatory passage between them when the yarn carrying frame is in assembled relation tothe dye vat and container.

, The dye llquor being thus heated, it is important that a thorough agitation of it should then promptly ensue so that at its initial strength at the beginning of the operation it should reach every part of the suspended skeins and impart thereto the same shade of color initially. To effect this a volume of compressed air, under a pressure of about thirty pounds to the inch is forced through the air pipes in the compartment `16 and discharges upwardly through the perforated base plate of the vat and hence in the region of the suspended yarn. Air under such compression will, when released from the perforated pipes, expand instantly and produce a violent agitation of the dye liquor, and this entirely apart from and in addition to the effect of its velocity under the pressure used to force it through the pipes. After this application of compressed air, it is equally important to set up a circulation of the liquor, this being effected by opening the valves which govern ,the perforatedl pipe 46 which discharges into compartment 14, driving the liquor upward and over the adjacent end wall of the vat and toward the center thereof and thence downward through the perforated base wall of the vat. A reversal of the direction of circulation may then be effected by closing valve 45 and openingthe valve 53 and discharging compressed air through the perforated pipe 50 .and through the compartment 15 at the opposite end of the machine.

The marked utility of my invention in this regard is not merely in providing a circulation. of the dye liquor comparable with that produced by mechanical means or even by air under atmospheric pressure, either of which is, in substance, merely a stirring, but by employing compressed air as the agitating and finally as the circulating medium and by means of the arrangement of piping and appropriate manipulation, a perfect circulation. and in reversible directions, as well as a preliminary and most thorough, as dis tinguished from a merely local, agitation of the dye liquor around the suspended yarns at the be inning of the dyeing operation, may be e ected, resulting, in a more completeapplication to the yarn of the dyeing lifquor at its initial strength and consequently e Having thus described my invention, Il claim:
