2` Claims.' (C1. is-188) This inventionrelates to a dyeing machine for dyeing wool, rayon, cotton and the like, the general 'object of the invention being to keep the material immerseddn the `dyeing liquid at all times, thus insuring'a `uniform color and penetration to all parts of material by the dyeing liquid. lAnother object of the invention is to provide means for supporting the material in loops in the machine'with means for slowly turning the loops at4 intervals and in opposite directions.

. Another object of the invention is to provide means'for adjusting the lower supporting means of; the loops to suit the` length of the loops.

'Ihisinvention also consists in certainy other features of construction and in the combination and .arrangement of the severalparts to be hereinafterfully described, `illustrated in the accom` panying drawings and specically pointed out inthe appended claims. o l, 4 -I`n .describing the invention in detail, reference will behad to the accompanying drawings where-` inilike` characters denote like` or corresponding parts throughout the several views,- and in which: Figure 1 is an elevation of the invention show-` ing'theframe raised from `the tank.

In these drawings the letter A indicates the www@ ,11S provided .with a Short` #QP Piece at one end thereof and a vertically arranged` transversely extending partition member 2 extending across said end portionof the tank and a horizontal plate 3 `covers the top of the space formed by the partition member 2 andthe adjacent end wall of the tank. This plate 3 is formed with a large circular openingv 5v in itsl center and a plurality of holes 6' are arranged in the plate between the center hole or opening and each end of the plate. A shaft 6 passes vertically through the top piece I and is journaled inthe o bottom of the tank as shown at 'I and a sleeve 8 is fastened to the shaft and carries a propeller 9 which is located ingthe lower part of the `space formed by the partition member 2 and the adjacent end walls of the tank. A motor M is fas'- tened to the. top piece I and gears 9 connect the motor shaft with the `upper, end of theshaft 6 Thus the dyeing liquid placed in the tank willlbe i agitated and `caused to-circulate and this liquid is heated by steamintroduced into the pipes I which have horizontal parts II in the bottom of the tank which are provided with perforations I2.

A frame Bis adapted to be placed in the tank through the open top thereof` and to be removed therefrom by means of a suitable hoist to be connected to the stays I3 connectedv to the stationary parts of` a` cover C,V these `stationary parts being connected by uprights I4 to thetop of the frame B. The cover C is `provided with the hinged doors vI which carry` the eyebolts I6 which are to receive bars for holding the frame from shifting while in the tank.

The Aframe B includes the four corner posts I'I,

the two posts -at one side of the frame being connected together by a side beam I8 and the other two posts being connected together bya side beam I9. The inner face ofthe beam I8 has a pluralityof vertically arrangedslots ory grooves therein opening out through the upper edge of the beam and terminating at their lower ends in circular recesses 2l, see Figure 8. grooves land recesses are to receive the rounded reducedends 22 of bars 23 of square shape in cross section, the other endlof each bar having a reduced part 24 whichis of square shape in cross section. `The beam 1I91carries a plurality of rotary bushings 25, one of which is arranged opposite each recess 2 Iwand the inner end of each bushing has a square recess 26` therein for receiving the square end'24. `The .outer end of each bushing has a shank 2'I extending therefromof non-circular shape in cross section which receives the pair of collars 28 between which is placed the toothedwheel 29, the parts 28 'and 29 being held These tightening the chains 49.

on the shank by a nut 30 .as more clearly shown in Figure 12. A shaft 3| is journaled in one of the posts'which supports the beam I9 and carries a pair of sprockets 32 and a small sprocket 33, a chain 34 passing over the small sprocket and over a sprocket 35 on a shaft 35 rotatably supported on a part of the cover C. A shaft 36 is carried by the sliding block 31 at the other end of the row of wheels 29 and this block can be adjusted by means of a set screw 38. A pair of sprockets 39 is fastened to the shaft 36 :and a` pair of endless chains 40 pass over the sprockets 32 and 39. Portions of the two chains 40 are connected together by the bars 4I for engaging certain teeth of the wheels 29 so that each time a'bar 4I strikes a tooth the Wheel will be' partly turned and, of course, this motion will be imparted to the bar 23 to which the wheel is attached. By only providing a few of the bars 4I l the square bars 23 will only be partly rotated at infrequent intervals and by making the drive for shaft 35 `a reversible one the chains will cause the square bars 23 to be rotated or partly so rst in one direction and then in the other. Of course, the block 31 and the screw 38 provide means for Lower side beams 42 areislidably arranged on the posts I1 and one beam has recesses 43 in its inner face While the other beam has transverse holes 44 passing therethrough. Round rods 45 are adapted to be passed through the holes with one end of each rod engaging a recess 43 and the other end fitting in a hole 44. After the rods 45 are put in place a bar 46, slidably supported on the outer face of the beam 42 which has the holes 44 therein is moved to place the holes 41 therein out of register with the holes 44. Of course, when the rods 4.5 are to be putin place or removed the sliding bar 46 is adjusted to place its holes 41 in registry with the holes 44.' As shown .in Figure 5, this sliding bar 46 slides through the guides 48 carried by the beam 42 and it is held in the position shown in Figure 5 by the clamping device l49. Each beam 42 can be slidably connected `with the posts I1 in any suitable manner though I prefer to form notches in the inner portions of the beams 42. through which the posts I1 pass and then plates 42' are fastened to the inner faces of the beams 42 to cover the notches so as to slidingly hold the beams to the posts.

Each beam 42 can be adjusted vertically on its posts I1 by means of they handle lever 50 pivoted to one post by a p`in 5I which may be placed in any one of a row of holes 52. Diverging links 52 are pivotally connected at their upper ends to an vintermediate' part of the lever and have their lower-ends pivoted toa beam 42 as shown at 53. Each lever is held in adjusted position through means ofan arcuate bar 54 depending from a part'of the upper portion of the frame vand having an arcuate longitudinally extending slot 55 therein, the side walls of which are notched as shown at 56 and a latch button 51 is carried by a handle part 58 rotatably arranged in the lever 50. Thus by turning the part 58 the latch button can be removed fro-m a' pair of the notches 56 and the lever adjusted upwardly and downwardly and the latch button placed in another pair of notches as shown more clearly in Figure 1'0. As shown inlFigures 10 and l1 the latch button includes a rectangular part which has a sliding t in a pair of the notches 56 and a circular part which is connected with a nut 58" on a threaded part of the shank of the part 58.

Thus by turning the member 58' in an anticlockwise direction the nut 58" will be fed toward the end of the threaded part carrying the button 51 with itv until the rectangular part of the button passes out of the space formed by a pair of the notches 56. Then the parts can be adjusted to another pair of notches and the member 5B' is turned in a clockwise direction which will cause the nut and button 51 to move inwardly to place the button or the rectangular part thereof in said other pair of notches.

Brackets 59 are carried by the posts adjacent the under parts of the beams I8 and I9 and these brackets support the rods 58 and brackets 59 extend upwardly yand inwardly from the beams 4.2 and support the rods 60. The rods 58 and 60 prevent spreading movement of the Ayarn supported on the members 23 and 45, as shown in dotted lines at 6I in Figure 3.

It will be seen that the square bars can be raised at their ends which engage the grooves 26 and recesses 2|, after the frame has been lifted tothe position shown in Figure 1 and the loopslof yarn placed over them so that'the loops will be suspended from these bars 23. Then theV round bars 45 are moved outwardly through the holes 44 after the bar 46 has been adjusted to v place its holes in registry with the holes 44 and then these bars 45 are replaced and passed through the lower ends of the loops of yarn after which the bar 46 is moved to the position shown in Figure 5 and locked in position by the clamping device 49. Then the lever 50 is adjusted to cause the bars orrods 45 to properly engage the lower ends of the loops. ered into the tank, the motor M started to agitate and circulate the dyeing liquid in the `tank and the shaft 35 is started to operate the chains 40, the upper reaches of which ride over the collars 28 and every time a rod 4I strikes a tooth vof a wheel, said wheel will be partly rotated and this movement willbe imparted to the rod 23, the square end of which is placed in the square recess 26 of the bushing 25 being so moved. Thus. the loops of yarn are partly revolved at intervalsA 'Ihen the frame is lowi andas before stated by reversing the shaft 35' l this partial revolving motion can be reversed.

Uprights 63 extend upwardly from the top of the tank'for supporting the cover member C in position shown in Figure 2 and an upright '64 extends upwardly from the top of the tank and carries` a stub shaft 61 having a tongue on its inner end for engaging a groove 68 in the shaft 35 when the frame B is in lowered position. A

pulley or gear 69 is fastened to the shaft 61 and is suitably connected to a reversible motor, not shown. A removable bar is arranged at one end of the bottom of the frame, Ysaid bar being provided with -a latch 66 at each end thereof -for holding it in position and by removing the'bar loading or unloading of the frame is facilitated. It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may bey made in the construction and in the combination and arrangement .of the several parts pro-` vided that such changes fall within the scope of the appended claims.
