3 Claims.

This invention relates to devices for stripping waste yarn from holders such as bobbins, cops,

spindles and the like. More particularly the invention relates to a knife for cutting through the convolutions forming the waste portion of a 5 wound yarn body so as to permit the ready removal of the waste from the holder for rendering it ready for immediate use in the manipulation of yarn under treatment.

In the artificial silk industry, to which this n invention is especially applicable, although not restricted thereto, the yarn, after spinning, is subjected to various treating and finishing operations, during which it is often transferred from one spool to another before it is ready for shipment. Each time the yarn is unwound from one spool and rewound upon another, the lowest layers are unfit for commercial use due to various defects inherent in the process and accordingly such layers are not unwound from the feed spool but are stripped therefrom. These defects in the manufacture of the yarn exist particularly in the case where the yarn is first wound in a wetcondition upon a spinning bobbin, then washed, dried, and rewound while being twisted onto another bobbin, the yarn in the layers immediately adjacent the hard core of the spinning spool being prevented from shrinking properly upon drying and, therefore, possessing different dyeing properties from the yarn forming the upper layers of the yarn body. Again, when the yarn is transferred from the twisting bobbin to a skeining reel or similar device, the layers of yarn first laid upon the twisting bobbin do not possess the same degree of twist as the upper layers thereof. This variance between the inner and outer layers of yarn onthe spool has resulted in the general practice of the rewinding of the outer layers for normal use while permitting the inner layers to remain on the twisting spool from which they are 40 later stripped.

In the past, various kinds of knives and similar instruments have been used for stripping the waste portions of yarn from the spools and they have proven more or less satisfactory, but they have failed to permit the stripping operation to be performed as quickly and economically, and with as little effort as the present device. One of the earliest methods of cutting thebody of 5o waste yarn for easy removal involved the employment of an ordinary steel knife blade by means of which the body of yarn was slit longitudinally and then removed. It was found that the-cutting of a thin layer of artificial silkyarn from a stiff core involved frequent injury to the bobbin, and its consequent'unfitness for further use. In order to minimize this injury to the bobbin 9. hard rubber knife was substituted for the steel blade in the slitting, of the yarn and, while this lessened the amount of injury to the bobbin, such knife proved inefflcient because it required frequent sharpening and necessitated greater effort on the part of the operator. A further development along this line involved the use of a hard rubber, saw-toothed knife, which proved more succmsful, although such knife required frequent sharpening to maintain its cutting efliciency. However, the hard rubber, saw-toothed knife was very unsatisfactory when used to sever yarn from perforated spools, since the teeth of the knife caught in the perforations of the spools and retarded the cutting operation.

It is, therefore, an object of the present invention to provide a novel'and efiicient cutting implement for severing the waste yarn on bobbins and the like so that such yarn holders may be again placed in service. Another object of this invention is the provision of a device which will permit the quick removal of the waste yarn from a bobbin or spool without injury to the holder itself, with the least 25 possible effort on the part of the operator being involved.

The invention contemplates the provision of a steel instrument for severing yarn from bobbins and the like which has the qualities referred to and which may be used indefinitely without requiring sharpening so as to eifect economies in time, labor and material.

Other objects and advantages will be apparent from the following detailed description when con- 35 sidered in connection with the accompanying drawing wherein- Figure 1 is a view of the assembled cutting device in side elevation;

Figure 2 is a part plan view of the cutting end of the device shown in Figure 1;

Figure 3 is a cross-section of the blade taken on line 3-3 of Figure 1;

Figure 4 is a perspective view of the device;

Figure 5 is a sectional view taken on line 5-5 of Figure l;

Figure 6 is a sectional view taken on line 6- of Figure I Figure 7 illustrates the use of the device in a stripping or cutting operation, and

Figure 8 illustrates a modified form of implement made in accordance with this invention, in that anadJustable-blade is provided.

Referring to the drawing in detail the numeral vulcts, or any other arcuate undersurface l designates a handle. This handle maybe made oi wood hard rubber, phenol condensation prodsuitable material. Secured to the handle is a cutting blade 2 which is T-shaped in cross-section (see Figure 3) Cross piece 3 of the T forms the base of the blade, the cutting blade being constructed of a'wear resistant material such as wrought iron, or which may be more desirable, stainless steel. Y

' which follows the contour of the usual circular holders and the forward portion of the base is beveled and sharpened to form a wedge shaped cutting edge 4. A cutting edge I is formed on the forward upright portion of the T-shaped blade and this cutting edge extends at an acute angle to the base 3.

Handle l and blade 2 are assembled as shown' in the drawing (see Figures 1 and 4).. A slot t is provided in the handle as shown in Figure 4 to permit the handle to fit over and receive the upright portion of the cutting blade. Screws 1 and i are employed for securing the handle and blade together, screw 1 passing freely in-an opening I in one side of the handle, then through an opening 9 in the blade. and being screwed into the opposite side of the handle beyond the blade for causing the walls of the slot 6 to be drawn tightly against the blade when the screw is tightened. The screw 8 may be secured in the handle in the same manner as screw I, but in order that the handle may be adjusted with respect to the blade so as to be pivoted around screw 1 as an axis. the blade may be provided with an arcuate slot (not shown). The adjustment of the handle with respect to the blade may be accomplished by threading the screw 8 into the blade, as shown particularly in Figure 6, and providing slots III in the handle. r

In the modification shown in Figure 8 thecuttingedge H on the upright portion of the T- shaped member may be disposed at different angles to the base 3, the adjustment being eflected by the movement of section I! on which the cutting edge is formed. Section II is pivoted to the upright portion by means of a pintle It and it also has a bolt ll afiixed thereto. An arcuate slot I! is formed in the upright portion of the T-shaped member, the slot fitting over the bolt suiilciently loose so that the section It may be pivoted about pintle I! to a desired position with the bolt moving in slot l5. When the cutting edge II is set at the desired angle with respect to-the base 8, a nut It threaded onbolt II is tightened whereupon section I! and the T-shaped member I are secured in the adjusted position. The lower end or section It is received within a slot ll arranged in base 3 so that the cutting edge will always be presented immediately adjacent the base even when section I! is adjusted to extreme positions.

The operation of the device is more readily apparent by referring to Figure '1 wherein a circular holder l8 is shown. This circular holder supports thereon a representative amount of waste strandular material It. An operator graspsthe device by the handle L and inserts the forward end 4 of the cutting blade 2 beneath the body of strandular material whereupon he pushes the knife longitudinally toward the opposite end of Thesaidbaselhasan' material wound on circular holders. to be understood that, while I have described one 'the operator. The specific design of the cutting surface makes the tool very adaptable for this operation since the arcuate undersuriace of the blade permits the operator to press downwardly withthe necessary force to maintain the position of the upright portion of the blade and also force the wedge-like portion beneath the coils of yarn without injury to the holder. In addition to this, the arcuate conformation of the undersurface oi the blade causes the'blade to move forward in a straight line from one end of the holder to the other and the sharpened edge l of the wedge-like member prevents the blade from moving upwardly, which would thereby otherwise leave some of the lower convolutions of yarn unsevered.

While I have described my invention in its application to the artificial silk industry, it is obvious that the invention may be applied equally well to the severing of other kinds of strandular It is also specific form of my invention, modifications may be made in the shape and arrangement of the parts without departing from the spirit and scope of the invention.
