Patented May 31, 1938 UNITED STATES PATENT OFFICE Claims.

This invention relates to a dyeing apparatus. The object of the invention is the production of dyeing apparatus with which hats or other objects are dyed the same color and shade, by 5' maintaining them at all times during the operation of dyeing in the dye liquor. This condition is secured by dyeing said hats or objects in an operating tank having covers, the operative positions of which can be easily adjusted.

The second object of the invention comprises means wherewith the direction of the ow of the dye liquor can be reversed and thereby efficiently penetrate the hats or other objects operated upon.

The third object of the invention is the production of means wherewith any fumes generated during the process of dyeing can easily escape.

In the accompanying drawing Fig, 1 represents a top plan View of the dyeing apparatus and Fig. 2 shows a section of Fig. 1 on the line 2, 2.

The dyeing apparatus comprises the conical oval shaped dye liquor reversing container designated in its entirety by the numeral 28. The said container is indicated having the conical oval shaped wall 2l, with'the flange 22 at its upper end, and the lower portion of the wall 2l joins with the fiat bottom 23. Drain piping 24 with the outlet valve 25 extends from the wall 2l. Journal brackets 28, which may be provided with stuffing boxes, are indicated with the journal bearings 29, The latter are fastened to the outer face of the wall 2i diametrically opposite each other. A bed plate 38 supports the journal brackets 28. A foundation 32 having the longitudinal gutter 33 and the cross gutter 34 supports the bed plate 38. The drain piping 24 leads to the gutter 34. An electric motor 38 having the armature shaft 39 is supported upon the bed plate 39. A directional relay 49, shown only diagrammatically, is provided for the electric motor 38. A propeller shaft 42 extends through the journal bearings 29 and has fastened thereto the propeller 43.

An operating tank is designated in its entirety by the numeral 5D. The tank 50 comprises the 7 bottom wall 5|, having a plurality of perforations 52. The wall 5l is supported upon and fastened to the flange 22. An oval shaped vertical wall 54 is supported upon the wall 5l and the angle iron 55 connects the walls 5| and 54 and the flange 22. 50' At the upper end of the wall 54 is indicated thereturn shaped flange 58, and the angle iron 59 is interposed between the wall 54 and the said flange 58 and fastened thereto.

A top cross wall is indicated at 60 with the opening 6|. A vent-funnel 62 extends up from the wall 80 over its opening 6l. The upper end of the funnel 62 is provided with the reinforcing band 63, and from the latter extend eyelets '54. To each of the latter is fastened one end of a supporting chain 85. Angle irons 61 extend crosswise upon the cross. wall 80 and are fastened thereto. The cross wall 68 is fastened to the top of the tank by means of the bolts 68.

To the cross wall are hinged a pair of outer covers, each designated in its entirety by the numeral 10, by means of hinge connections 1|. Each of the covers 19 has extending therethrough an opening 12, and has formed therewith a plurality of depressions 13 to form strengthening ribs. A pair of handles 14 extend up from each outer cover 18, and each of the latter is strengthened with the angle iron 15. From the outer face of each of the covers 19 extends a ,supporting hook 18 and the fork shaped clamping hook 19. From the bottom face of each cover 10 extend a pair of journal brackets 83. v

A pair of intermediate or inner suspended covers are each indicated in its entirety by the numeral 85. Each of the covers on its inner side is provided with the upwardly extending curved portion 86 having the edge 81. The said edges 81 are spaced from each other to form a vent opening 88. The curved portions 8B are provided to prevent injury to the objects dyed when the covers 85 are moved to different positions. TheA outer end of each cover 85 is indicated at 89. An Veye bolt extends up from each cover 85 adjacent to its outer end.

From the upper face of each cover 85 extend a pair of journal brackets 92.

Four links are each indicated at 95. Each of said links has its upper end inv hinged connection with one of the journal brackets 83 by means of the pin 93 and its lower end is hinged to one of the journal brackets 92, by means of the pin 94.

It will be noted that the pins 94 are closer to the vertical axis of the apparatus than the pins 93, and thereby the links 95 are positioned in inclined positions, when the inner covers 85 are in their operative positions. By reason of the centers of the pins 93 being horizontally spaced from the centers of the pins 94 ltoward the outer ends 89 of the covers 85, the said covers are forced `to position said ends 89 to bear against the inner end face portion of the wall 54 of the operating tank 58. By this means there is prevented any considerable leakage between the said ends 89 and the adjacent face of the wall of the operating tank 50.

A chain 98 extends from each eyebolt 90, leads through the adjacent opening 'l2 in its cover 10. The chains 96 are adjustably clamped in different positions in the adjacent forked shaped clamping hooks 19 to tilt the covers 85 to different positions.

To operate the dyeing apparatus the outer covers 'l0 are lifted to their vertical positions as indicated in dotted lines at 10a, by means of the handles 14, and are held in place by connecting the supporting chains 65 to the supporting hooks 18. By this means the inner covers 85 are also lifted to their raised positions as indicated in dotted lines at 85a.

The operator then charges the operating tank 50 with the hats or other objects to be dyed, and

dye liquor to about the level of the line is.

poured into the apparatus. The dye liquor will iiow to the reversing container 20 through the perforations 52 of the wall 5i. Next the covers l!) and 85 are lowered as shown in full lines in Fig. 2. The electric motor 38 is now started, by means of which the propeller 43 is turned and the dye liquor ilows from the container 20 to the op` erating tank 50, through the perforations 52 at one side of the wall in the direction of the arrows |05, and penetrates the hats or other objects to be dyed in the said operating tank 50 to dye the same. The dye liquor returns to the reversing container 20 at the opposite side thereof.

The circulation of the dye liquor from the container 2G to and through the operating tank 5D is repeated for a predetermined number of times. The rotation of the electric motor 38 is then automatically reversed by the directional relay 45, by means of which the propeller 43 is turned in the reverse direction for a predetermined number of times. The dye liquor no-w ows in the direction reverse to that shown by the arrows m5, and the hats or other objects are again penetrated by the dye liquor. The

i electric motor 38 by means of the relay 4|) is then reversed to its original direction and the steps are repeated until the hats or other objects are thoroughly penetrated and dyed.

If it is desired to drain the apparatus the outlet valve 25 is opened and the dye liquor Will flow through the drain pipe 24 into the cross gutter 34 and then will be discharged into the longitudinal gutter 33 to a tank or other container as desired.

Attention is called to the fact that the hats 0r other objects dyed remain at all times during the dyeing in the operating tank 50 completely immersed in the dye liquor in said operating tank, to secure the same reaction with the dye liquor to dye all the hats or other objects the same shade and color. In case the level of the dye liquor falls below the level indicated at |00 and below the level of the inner covers 85, the operator lowers said covers 85 by lifting the chains 96 from the fork shaped clamping hooks 19 and lowers the said inner covers 85 to a position as indicated at 85a, to maintain all the hats or other objects below the top level of the dye liquor in this position as well as in the original position of the inner covers 85, the suspension of said covers 85, by the links 95 tends to position the ends 89 of the covers against the inner end faces of the wall 54. The vent opening 88 between the edges 8l of the inner covers 85, the opening 6| and the vent funnel 62 permits the escape of any fumes generated in the apparatus.

Various modifications may be made in the invention and the present exemplication is to be taken as illustrative and not limitative thereof.
