- 12 Claims.

The invention relates to feeding mechanism for cloth or like material in endless bands, and more especially to apparatus for feeding the cloth through a suitable vat containing liquid, as in the dyeing of cloth. Apparatus of this nature has been devised with a reel located between the vat and the pleating reel and driven by the latter so that a continuous hand of cloth may be passed through in a number of turns. Difilculty has been experienced with this form of the apparatus in connection with the feed due to resulting tension on the goods and piling up of the goods in the apparatus trough.

The invention has for an object the provision of means, in apparatus of the aforesaid type, tor maintaining at all times the desired tension on the goods during its return passage, as well as to maintain a uniform teed thereof.

another object of the invention resides in the provision of apparatus which will accommodate various weights of goods.

in carrying out the invention, the driving intermediate reel is designed to act also as a compensating reel in providing the same with a conical periphery with respect to which the cloth is displaceable as by causing the said reel to he axially adjustable, by bodily displacing the goods, or by effecting both operations. The displacement is to be effected, moreover, in accordance with the amount of material delivered by the said compensating reel, as by allowing the material in its passage from said compensating reel to the pleating reel through the usual. trough to first pass upon a balance pan located in advance oi said trough, the amount accumulating on the pan determining the degree of reciprocation of the reel and/or the material.

To enhance the eilect of the conical drive surface of the compensating reel on the band of material passing thereover through the bodily displacement of said band, a bifurcated element'is located in advance of the said reel and is likewise reciprocated under the action of the weight of the material accumulating in the balance pan, but this reciprocation, which is arranged to be parallel to the rotatlonalaxls of the compensating reel, is in a direction opposite to that of the said reel.

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings, in which:

Fig. 1 is a plan view of a. dyeing vat and associated apparatus for passing material therethrough shown in phantom lines, the portion embodying the novel features of the invention being indicated in full lines.

Fig. 2 is a similar end view; and Fig. 3 a front view thereof, with counterweight removed.

Referring to the drawings, ill designates a suit- 5 able frame for supporting the feed and drive mechanisms for the material which is in the nature of an endless band ll, said material being delivered into a suitable dyeing vat or tank It designed to contain, for example; a dyeing solution. w This feed is effected from a pleating reel ii of the usual type, the endless band passing successively between adjacently and horizontally disposed separated plus it located over the one end of the vat and. is withdrawn from the latter by is a drive reel is. Suitable guide rolls it and Ill are provided to direct the band in its course through the vat; and a transverse trough or the like it returns the material withdrawn from the vet by the drive reel l5 to the far end of the W pleatingreel it.

The said drive reel is rotated from the pleating reel ill by means of a sprocket chain 19 and driving pin iii, said pleating reel being driven from suitable prime mover (not shown) and connected with the shaft it of the former. The apparatus hereinbefore described is similar to that in general use, and no claim is made to the same. However, dilhculty has been experienced in connection with the passage of goods over the drive reel due to difference in the feed rate and the withdrawal rate of the goods and accumulation of the same in the vat, or to the use of goods of different weights in the same apparatus.

In accordance with the invention, provision is 35 made to compensate automatically for any such tension chances and secure a uniform delivery from the reel ill, avoiding substantially slippage of goods with reference to said reel. This is accomplished by constructing the reel ill of conical 4m periphery, the slats 25 thereof being accordingly inclined, and by arranging said reel as a Whole to be reciprocable axially. In addition, and to enhance the compensating action, provision is made also to move the goods bodily over the 4g periphery of the reel and in a direction parallel to its axis of rotation. Both of these actions are made dependent upon the weight of material delivered from the reel and occur simultaneously in directions opposite to each other.

To this end, the spindle 26 on which the reel 15 rotates is connected :with a reclprocable rod or bar 211 having a rack portion 28 designed to be engaged by the pinion 29 on a shaft 30. This shaft carries also a pinion 3| engaging a. rack portion 32 of a further rod or bar 33 reciprocable in a direction parallel to the rod 21 or rotational axis of the reel l5.

The arrangement is such, furthermore, that the respective pinions engage their racks at points 180 apart so that as shaft 30 is turned, reel l5 would be moved in a direction opposite to a bifurcated member constituted by pins 34 extending upwardly from the inner end of rod 33 and located in advance of the reel IS. The goods from the tank are designed to. pass between these pins from guide roll l6 to the surface of the reel I5, and are shiftable accordingly along said surface but in a direction opposite to any axial movement imparted to the said reel as a whole.

Motion for securing this opposite and simultaneous reciprocation is controlled by the material being treated as the same is delivered from the reel I5 and falls, not into the trough l8 as is the customary practice, but first onto an intermediate pan 35 of a balance comprising a lever having a pan arm 36, the lever at its far end having an adjustable weight 38 to determine the amount of balancing material upon the pan 35 required to throw the balance. reciprocable in a direction at right angles to the rotational axis of the reel and a stem 39 attached to its underside ,engages the free end of lever arm- 36 and may be guided, for example in a suitable tubular member 40 secured to the vat, in order to steady the action.

As the pan rises and falls in accordance with the weight of material thereon, the lever arm 36 will be correspondingly angularly moved; and this angular movement is communicated to the axle ll of a wheel 42 to which said lever is secured by fastening means 43. In turn, the angular movement of the wheel is communicated by the driving means 44 to the shaft 30 of the pinions,

effecting thereby the aforesaid reciprocations.

Thus, when material accumulates unduly upon pan 35 or is delivered thereto by the compensating reel I 5, the said pan will be depressed together with arm 36, which will cause the rods 21 arid 33 to be oppositely reciprocated in directions to carry the material to a slower rotating portion of the reel periphery. Conversely, if the amount of the material on the pan is reduced, the pan will rise and the arm 36 of the lever will be elevated, and the rods will be respectively reciprocated inv the reverse directions and the materialsubjected to a faster rotating portion of the reel periphery. By this expedient, the feed is regulated of the material in its return to the pleating reel and objectionable tension is avoided which may cause chafe marks and color streaks.
