This invention relates to improvements in yarn treating apparatus and has particular reference to a device for twisting or curling the filaments of chenille yarn about the core thereof.
' An object of the invention is to provide an improved apparatus of simple and practical construction which will efficiently twist or curl the filaments of a yarn by the use of a series of juxta posed elements through which the yarn is passed in and which are arranged to form spaces therebetween into which the filaments are received and twisted or curled about the core of the yarn as it is moved relative to said elements.
Another object is to form each of a plurality of yarn twisting elements of two plates which are separable from each other and arranged edge to edge, with the adjacent edges having registered recesses that combine to form apertures through which the yarn to be treated is passed.
The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawings which illustrate a preferred embodiment of the inventive idea.
In the drawings:
Figure 1 is a perspective view of a yarn treating apparatus constructed in-accordancewith the invention.
Figure 2 is a transverse sectional view taken substantially on the line 22 of Figure 1.
Figure 3 is an enlarged fragmentary detailed view, similar to Figure 2, and showing the spacing arrangement between the yarn treating elements of the apparatus.
Figure 4 is a fragmentary perspective view of one of said elements consisting of two separable plates which are hingedly supported upon the base of the apparatus.
Figure 5 is a longitudinal sectional View through the apparatus in its operative position, and
Figure 6 is a similar view showing the cover of the apparatus raised and the plates of one of the yarn treating elements separated.
Referring more particularly tothe accompanying drawings the numeral 1 indicates a base which may be of rectangular formation and the opposed side Walls of which are provided longitudinally thereof each with a row of openings 8 aligned with the openings in the other side wall so that yarns to be treated may be passed through the aligned openings. Within the base 1, two chambers are formed into which extend the valve controlled burner pipes Ill. The chambers 9 extend completely through the base I and at the ends thereof remote from the ends from which the burners project, said chambers are provided with heat exhaust fiues II. In the upper surface of the base i, and between the upper edges of the side walls thereof, there is formed a recess l2 adapted to receive a series of yarn treating elements [3 arranged longitudinally of the base and in juxta-position to each other. A cover M is provided for the elements i3 and said cover is ,T hingedly connected to the base! at l5 so as to 10 rest upon the upper edges of the side walls there of, the free end'of said cover being provided with handles I6 which enable the cover to be raised and lowered relative to the base.
7 As best shown in Figure 4, each of the elements l3 comprises a pair of upper and lower elongated plates I1 and 18 which extend lengthwise of the base 1 within the recess l2 therein, and which have adjacent ends projecting from the base at the handle end of the cover M, as shown in Figure 1. The other ends of the plates ll, I8 are loosely mounted for pivotal movement within the base by the two rods l9 and 20 which extend respectively, through openings 2| and 22 in the ends of said plates and project from the side walls of the base I. The pivotal mounting is such that the two plates of each element [3 are disposed in substantially vertical alignment with the lower edge of the upper plate resting upon the upper edge of the lower plate. In actual op- 3 oration, the upper and lower plates may shift slightlyrelative to'each other due to the passage of a yarn back and forth between the same, but this shifting is resisted to some degree by the weight of the'cover I4 which rests directly upon the upper edges of the upper plates H, as best shown in Figures 2 and 5. In order to provide apertures through which a yarn is passed, the lower edge of the upper plate and the upper edge of the lower plate are provided, respectively, 4 with registering recesses 23 and 24 which combine to form said apertures when the plates are in the operative position of Figure 5. These apertures are aligned with the openings 8 formed in the side walls of the base 1 so as to facilitate 45 the feeding of. the various yarns through the apparatus from one side to the other thereof. With the plates l1, l8 s'o arranged, the various elements I3 extend completely across the recess 12 in loosely abutting relation so as to provide intervening spaces shown as greatly enlarged at 25 in Figure 3, and which, in eifect, constitute grooves for receiving the filaments of a chenille yarn as the latter is passed through the apertures in said elements and which act to impart a twist to said filaments to curl the latter about the core of the yarn. The loose mounting of the plates l7, I8, on their pivots 19, 20, combined with the reciprocating movement of the yarn which is usually imparted thereto as it passes through the device, permits said plates to separate sufiiciently to allow the filaments to enter the grooves between the plates. By pivotally mounting the plates IT, IS of each element l3 on the base, or otherwise separably supporting the same thereon, it is possible to very readily clean the elements periodically of accumulated filaments in the spaces between said elements which become detached from the yarn during the twisting operation. This cleansing of the elements is accomplished simply by raising the cover [4 to the position of Figure 6 and then pivotally swinging the upper plates [1 of the various elements i3 to the position shown in said figure, thereby affording easy access to the plates and the spaces therebetween.
In practice, with the parts of the apparatus shown in the position of Figure 5, and with the burners l ignited, the ends of a plurality of chenille yarns are first passed through the various openings 8 and the apertures in the elements l3 from feeding reels on one side of the apparatus to take-up reels on the opposite side, in a manner well known in the art. Suitable mechanism of a conventional type, not shown, is used to draw the yarns through the apparatus either in a steadily advancing movement, or in a movement in which the yarns are continuously reciprocated as they are advanced through the device. During either of said movements, it has been found that the yarns will have a slight torsional twist imparted thereto which is probably due to the inherent quality of the yarn and also to their passage around guide pulleys or idlers interposed between the apparatus itself and the feeding and take-up rolls. This torsional twist of the yarns, however slight it may be, cooperates with the spaces or grooves between the elements l3 into which the filament of the yarn will enter, to twist or curl said filaments about the core of the yarn and the application of heat to the yarn as it is passed through the apparatus causes the filaments to remain in their twisted condition as the yarn exits from the device and is curled on its take-up reel.
