RAYON TRUCK.

Application filed September-14, 1928. Serial No Si)5,958.

This invention relates to stretchers for rayon silk.

It is the custom in handling skeins of rayon silkto support them on bars formed of aluminum tubes and to support the skein and bars assembled on a rack for the purpose of dry ing the rayon silk. The rack on which the aluminum bars have uniformly heretofore been supported have been made of iron or some other similar material that would cause the aluminum skein bars to become roughened and damage the rayon silk which came in contact with the roughened places.

It is the purpose of this invention to provide a rack for the support of the skein bars in such a way that the bars will not become lacerated and torn so as to damage the threads supported thereby.

It is the particular object of this invention to provide a frame for supportingthe aluminum bars carrying the skeins of thread on which there are provided supplemental cushion members made of soft and yielding material to immediately support the aluminum skein bars.

This is accomplished by providing the frame bars with a cushion surface of some other material than steel or iron. The other material used may be aluminum, copper, brass or fibrous material formed in such a way as to form retaining means for the skein bars.

For the purpose of illustration there is presented herewith in the drawings a preferred embodiment of this invention, which is shown by way of illustration and to which the in vention is not intended to be limited.

Fig. 1 is a side view of atruck showing a plurality of means for supporting and stretching skeins of rayon silk.

Fig. 2 is an end view with part of the operating means broken away.

Fig. 5 is a cross section of Figure 3 on line 5-5. b

Fig. 6 is a view showing one end of one of the cushion bars.

Fig. 7 is a View showing one of the skeins of thread and its skein bars.

Fig. 8 is a section on line 88 of Fig. 1. The device which is the subject matter of shape and has extending upwardly therefrom at each corner upright posts indicated by the numeral 3, which are adapted to support the stretching and supporting means for the skeins o-f rayon silk thread.

E Xtending across the upper ends of the upright post at each end of the truck is a cross beam or bar indicated by thenumeral 4, which tends to hold the upper ends of the posts.

There are shown inthis drawing two .sets of stretching and holding means for the skeins of thread. Each set is composed of similar parts locatedon each side of the frame. The stretching means is composed essentially of two bars extending longitudinally over the truck frame on each side of the truck. The upper bar is fixed to the frame and is indicated by the numeral 5. These barsare attached to the uprights of posts 3 by means of bolts or rivets indicated by the numeral 6. y

Associated with each fixed stretcher bar is a movable bar indicated by numeral 7, which is supported beneath the fixed bar and guided 7 in slots formed by the guide bars 8 and the uprights 3. .Just beneath each one of the fixed bars and attached to the upright post 3 are brackets 9, which have extending therefrom ears indicated'bythe numeral 10 by which the brackets are attached to the up right posts. The lower ear of each of these brackets serve to space the guide bar 8 from the upright for the accommodation of the movable stretcher bars. The lower ends of the guide bars 8 are attached to the upright by means of rivets 11.

It is understood that the guide bars 8 pro? vide guiding slots for both upper and lower movable stretcher bars. There are two sets of the brackets 9, each having a bracket attached to each one of the uprights. I

In each of the side pairs of brackets there extends a hand wheel shaft indicated by the numeral 12, which is locate the brackets Ill? 9 so as to have up and down movement there in. On one end of each of the hand wheel shafts on one side of the frame is a hand wheel indicated by the numeral 13, while on the other end of each of the four hand wheel shafts is a sprocket wheel indicated bynumeral 14. Connecting the two upper sprocket wheels and the two lower sprocket wheels are sprocket chains indicated by the numeral 15. By means of this sprocket wheel and chain construction each shaft of the upper set or the lower set of stretching members may be operated by turning one of the hand wheels 18. Each of the hand wheel shafts are threadec as indicated by the numeral 16 and receive thereon in threaded relation therewith nuts 17 stretcher bar.

7 Extending from each side of the nut are ears 18 to each of which is pivotally attached 7 attached to the stretcher bars 5 or to the stretcher bars 7 The hand wheel shaft is located between a fixed bar and a movable bar and has a toggle connection therewith by means of the nuts 17 and the links 19 by which the stretcher bars may be moved to or from eachother. Each end of the hand wheel shaft has at least two screw thread sections in which the threads are in different directions so that in the turning of the shaft the nuts thereon will move toward or from each other. hen the nuts are caused to move toward each other the stretcher bars are sep arated and when they are caused to move from each other the stretcher bars are made to approach each other.

The stretcher bars 5 and 7 are composed of such material assteel or iron and are adapted to have strength and rigidity. For the purpose of providing a soft and smooth surface for receiving and carrying the skein bars there is provided a cushion bar or a series of cushion bars indicated by the numeral 20. These bars may be made in section and are shown here as composed of 6 sections for each These cushion sections are attached to the stretcher bars by means of rivets or bolts indicated by the numeral 21. The bearing surface these cushion bars is scalloped orserrated in form," as at 22, PTO".

viding cavities in which the skein bars 23 may rest.

This device is used in connection with skeins of thread'24c which is supported by the skein bars. There are two bars for each skein of thread. One pair is supported by the upper stretcher bar while the other pair is beneath the movable stretcher bar and is adapted to seat in one of the notches therein. lVhen the proper number of skeins and the skein bars have been assembled on the stretching device the hand wheel is rotated so as to bring the nuts on each part of the hand wheel shaft to ward each other, thereby spreading the stretcher bars apartand stretching the rayon silk carried thereby on the skein bars. \Vhen the rayon silk has been. thus assembled and properly tensed the truck with the rayon silk thereon may be conveyed by the rollers to any suitable place for drying or other purpose. It has been found in actual practice that this stretching device with the cushion bars is very effective in that it does not cause the skein bars to become lacerated or roughened so that the silk is damaged.

Having thus described my invention, what I wish to protect by Letters Patent and claim as new, is set down in the following claims:

1. In a device of the class described, a sup port, a plurality of stretcher bars carried by said support, means for moving said bars to and from each other, and a protective cushion member provided for each stretcher bar.
