7 Claims.

This invention relates to an apparatus for arranging fabric in kiers or tanks, which apparatus is more commonly known as a kier piler.

necessary that the of a rope be piled ough and even treatment of the cloth in its entirety.

It is the purpose of this invention to provide a simple and improvedkier piler.

A better understanding of this invention will be had from consideration of the following drawings in connection with the following description and in which;

Figure 1 is a side elevation of a kier piler constructed in accordance with the invention and is illustrated in position over a kier;

Figure 2 is an end elevation of the same kier piler;

Figure 3 is a side elevation of to that shown in Figure 1;

Figure 4 is an enlarged detail of the cam and associated parts; and

Figure 5 is a sectional detail of slip ring construction.

As can be seen from the side opposite operating the bearing and the drawings, the entire apparatus is supported upon cross beams I which span the kier. These cross beams can be at any desired point above the kier, although for con- Figure 1 shows the cross mounted or travel upon tracks (not shown) positioned above the kiers to be served by the apparatus.

The kier piler itself consists of a feed tube or conduit 3 into which the fabric 4 in rope form is fed by any suitable means. Tube 3 is supported rotatably by a combination journal and thrust bearing 5, illustrated in more detail in Figure 5, and which retains the tube against downward movement while permitting rotation about its longitudinal axis. It will be understood that any standard type of bearing capable of supporting the tube for rotation and carrying the vertical thrust may be employed; The fabric to be treated and piled in the kiersis fed through the entire length of the tube which serves as a feeding means for conducting the fabric to a main drum or pulley l, rotatably supported by suitable bearings, in brackets 8 depending from a table or support 9, carried bythe lower end of tube 3 was to be rotatable therewith.

The entire assembly so far describedis rotatable about a vertical axis and specifically the axis of the tube 3 and is positively rotated in the bearing 5 by means of a motor H driving reduction gearing l3 terminating in pulley l5, all cararcund drum 7 then rotatably supported by the arms 23, also depend ing from the table 9, and then back to and around drum 5. axis in lined relatively to the axis of drum 1 so Although the velocity and weight of the rope of fabric is sufficient to rotate drum 1, it is preferred to positively drive The tangent roll is spring urged or into contact By oscillating loaded with the drum 1 by springs-45.

arms 43, the position of tangent spirit and scope of the invention as 2 roll 4| may be varied about the periphery of drum 1 and accordingly the point of departure of the fabric 4 from drum 1 may be varied depending upon the position of roll 4|. This and the velocity of travel of the fabric will determine the manner in which the fabric is piled in the kier. In order to vary the position of the tangent roll 4|, andcause the fabric to be piled as illustrated in Figure 1, one of the arms 43 is connected by a link 41 to one end of an arm 49, the other end of which is secured to a cam follower shaft 5| which is also rigidly fastened to cam follower 52 which engages a heart-shaped cam 53 secured to cam shaft 54. Cam shaft 54 also carries a pulley 55 driven by a belt 56 engaging a pulley 51 on the drum shaft. The linkage and. cam just described for variably positioning the tangent roll isso designed as to cause proper movement of arms 43 and tangent roll M as to cause the fabric to be piled radially of the kier; one form of piling being shown in Fig. 1. As the entire unit is rotated the fabric will be piled over the entire kier floor. Obviously different cams and linkage can be employed to cause a different throw of the fabric.

From the foregoing, it will be seen that as a rope of fabric is fed into conduit 3 it descends through the conduit and engages drum 1, taking one complete turn therearound passing under tangent roll 4| which through heart-shaped cam 53' controls; the point of departure of the fabric. The position of tangent roll 4| is constantly varied as the entire device is rotated about the axis of conduit 3 thus causingv the cloth to be piled evenly and throughout the entire kier without tangling. It can also be seen from the foregoing that inherently the foregoing mechanism can be used to pile the fabric in the kier in at least two ways, If the linear travel or velocity of the fabric, in feet per second for example, is equal to the product of the number of complete oscillations per second of the tangent roll and twice the radius (i. e., the diameter) of the kier, the fabric will be laid or folded as shown diagrammatically in Fig. 1. On the other hand if the velocity of the fabric is greater, the fabric will be piled substantially evenly over the entire kier floor as before, but the fabric will be in bunched or crowded radial folds rather than in folds or layers ofa single thickness or lamination. The foregoing mechanism is comparatively simple in construction and comparatively light in weight so that it is portable and can readily be moved from one kier to another.

It, will be obvious to those skilled in the art that minor changes may be made in the details of construction without departing from the defined in the appended claims.
