Fig. 9, is a fragmentary section onthe line 99, Fig. 4.

With reference to the drawings, the machine comprises the usual vat body 1, there being provided a valve-controlled port 3 for discharging the. spent dyes. Pivotally mounted on a shaft 4 on the body and adapted to occupy a position in the vat is a perforated receptacle or cage 5, sail cage being adapted to be elevated to a position shown in Fig. 6 for discharging therefrom the articles which have previously been immersed in the dye bath. For this purpose, the cage is provlded at each side with a lever arm 6-, each of these arms being connected by means of it connecting rod 7 with a bell crank lever 8 pivotally secured one at each side of the vat, the pivot point in each instance'being designated by the reference numeral 9. Each of the levers 8 is adapted to engage a cam 10 carriedon the inside of a gear wheel 11 mounted one at each side of the casing on a. shaft 12 journaled in the latter. The gears 11 are rotated -which mesh respectively with the gears 11.

The cage 5 is shown in the normal operating position in Fig. .1, and the cam 10 is such that when the gear ll is rotated in the direction of the arrow in Fig. 1, the bell crank lever 8 is oscillated in such manner as to exert a pull upon the rod 7 which, through the lever arm (3, carries the cage to the elevated position illustrated in' Fig. (3.

Iivotally mounted on a shaft 25 journaled in the body 1, one at each side of the body, is an arm 26, the said arms having journaled in the upper ends a paddle wheel 27. The normal positions of the arms and wheel are illustrated in Fig. 1,-the paddle Wheel being partially immersed in the dye bath whereby rotation of-the paddle wheel in a manner hereinafter described agitates the bath. The arms 26 are adapted to be thrown upwardl and rearwardly by the same cams 10 which operate the cage, and for this purpose each is provided with a cam roller 28 which engages its respective cam 10, the arrangement being such that the cams, when operating to shift the aforedescribed parts to the elevated positions, act upon the arms 26 in advance of the bell crank lever 8 whereby the arms 26 with the paddle are shifted upwardly in advance of the upward movement of the cage and are so made to clear the path of the cage in its movement intothe elevated position.-

As will be noted, the arms 26 also carry a hood or guard 30 which occupies a position over the top of the paddle wheel when the latter is in the normal low position and prevents the splashing of the dye from the vat as the paddle rotates.

For rotating the paddle wheel, there is provided in the present instance an electric m0- tor 33 mounted on a suitable bracket 34 at one side of the body. The shaft of the motor 33 is normally connected by means of a clutch 35 with a. worm shaft 36 journaled on the bracket 34, the worm 37 ,:of this shaft 'meshing with a worm wheel 38 on a short shaft 39 journaled in the bracket 34, this shaft carrying also a pinion 40 which in the normal position of the paddle wheel meshes with a gear 41 on the paddle shaft 42. Suitable. means such as a hand lever 43 is provided for operating'theelutch 35 to connect and disconnect the motor 33 from the shaft 36.

For controlling the operation of the motor 15, a control switch is provided in a suitable housing 45 secured at one side of the body, there being provided for actuating this switch a hand lever 46 mounted 'on one end of a short shaft 56 journaled in a bracket secured to the body, and having"a't its opposite end a lever 47, the switch 45 being a double throw switch to provide for reversal of the motor and the connection between the lever 46, and the switch elements being such that the switch is thrown into its alternative operating positions and into a neutral inoperative position by corresponding movements of the lever 46.

In the present instance, this connecting mechanism between the said lever and the switch elements comprises a segment 50 which moves with the switch blade or blades and located on the exterior of the housing 45, the segment being provided with three pins 51 which, when the lever 46 is shifted from the neutral position, are engaged by elements 52, 52, carried by the lever, the relation between i the elements 52 and the pins 51.being substan tially that of the teeth of intermeshing gears.

An arm 55 is secured to the short shaft 56, to which the lever 46 is secured, and extends downwardly from the shaft, this lever being connected by means of a connecting rod 57 with an arm 58 secured to'a shaft 59 mounted in the body. This shaft 59 also carries a cam 60 adapted to engage one arm of a bell crank lever61 pivotally mounted at 62"in the body and having slung from a pivot pin 63 on the other arm a weighted arm 64. This arm in the normal position of the lever 61, which'the latter is permitted to assume. only when the lever 46 is in the neutral position, is adapted to :bear against the back of a brake shoe 65 which is carried by a sleeve 66 slidably mounted on the shaft 12,' and forces the shoe against a brake drum 67 carried by the gear 18. The cam '60 shown in Fig. 9 has a V-shaped recess oceupiedby the lower arm of the lever 61, and in the normal neutral position of the lever 46,

the lever 61 rests in the bottom of the notch.

as previously stated the In this position,

the ever brake is applied. When, however,

46 is shifted either to the right or left from neutral position, the lever -61 is forced out wardly from the bottom of the notch, and the upper. arm is thereby elevated, carrying with it the weighted arm 64', the pressure of the weight thereby being removed from the brake shoe. An arm 68 fun'tions as astrut between'the lever 61 and the weighted arm 64, as shown in Fig. 4.

Pivotally secured to the lever 47 and extending on opposite sides thereof is a pair of connecting rods 70 and 71 which respectively attach to levers 7 2 .and '7 3 pivotally secured at 74 and 75 respectively .to the body, the

lever 72 occupying a position in the path of one of the arms 26, and the lever 7 3 a position in the path of the arm 6 for a purpose which will be described hereinafter.

The operation of the machine is as follows:

A dye having been placed in the vat 1, an article or articles to be dyed are placed in the .cage which occupies "a position in the vat. The paddle wheel 27 is then set into operation either by starting the motor or by throwing in the clutch 35 after the motor has been started. After the dyeing operation has proceeded a suflicient length of time, the operator may throw the lever 46 to the left,(see Fig. 1) in the direction of the arrow, with the result that the brake 65 is released and the motor 15 started in a direction causingrotation of the gear wheels 11 and the shaft 12 in the direction of the arrow in Fig. 1. At the same time, the lever 7 3 is moved as indicated by the arrow in Fig. .1, and is thereby shifted into the path of the lever arm 6, which is moving downwardly and inwardly toward the vat. The rotation of the shaft 12 by reason of the action of the cam 10 elevates the paddle wheel and the cage to the positions shown in Fig. 6, at which time, as clearly indicated, the arm 6 has engaged the lever-73 and shifted it to the neutral position, thereby stopping the motor and preventing further movement of the cage. The angle assumed by the cage while in this position is such that the wet goods can be allowed to remain in the cage until most of the dye liquor has drained back into the vat through the perforation in, the cage. The goods can then be easily drawn out of the cage and dropped into a movable receptacle or truck placed in front of the machine for the purpose.

After the cage has been emptied, the cage and the paddle wheelcan be returned to their normal position by moving the lever 46 to the right, which will start the motor and drive the cams in the opposite direction shown by the arrow, allowing the cage and paddle to fall byv gravity into their respective positions shown in Fig.1. Movement of the lever 46, however, to the right under the action of the lever 73 elevates the lever 72 into the path of the arm 26 at that side of the body so t at as the latter approaches its normal depressedposition, it bears against the lever 72 and through the connecting rod 70 draws the lever 46 into the neutral position, thereby stopping the motor 15 and applying the brake 65. The mechanism is now 1n position for a furtherdyeing operation. .It will be noted and adapted to occupy a position-in the latter,

start the operation of the machine in either direction, the apparatus needs no further at-i tention.
