l HENRY A. OWEN, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO WHITIN lV-IA-- CHINE WORKS,` OF WHITINSVILLE, MASSACHUSETTS, VA CORPORATION OF MASSA-'- l eHUsnTTs.
TENSION DEVICE.
Application filed September 5, 1925. Serial No. 54,658.
To all whom t mag/concern.'
Be it known that I, HENRY OWEN, a citizen of the United States, residing at lhitinsville,` in the county of lVorcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in rlension Devices, of which thel following is a specification.
My invention relates to tension devices for yarn and thread winding machines.
The principal object of the invention is Yto provide a vdevice in which the tension of Vthe yarn may be regulated with precision andl any desired amount of tension maintained without subjecting the yarn to undue strains.
lAnother object of the invention is to provide a construction whereby a desirable cleaning of the yarn is eected. The principle of the combination will be made apparent from the illustrative embodiment shown in the drawing, wherein- Figure 1 is a cross section of a portion of a spooler of conventional type showing my improved tension device incorporatedA therewith;
Figure 2 is a plan view of the tension device;
Figure 3 is a sectional elevation on line 3 3 of Figure 2;
Figure 4l is an end elevation of the tension device; and Y Figure 5 is an enlarged sectional view showing the relative positions of the tension disks and the supporting bearing of the lower disk.
Referring to the drawings, Figure 1 shows the yarn 2 being drawn from a stationary bobbin 4 through my improved tention device and then wound on the rotating spool 5. d I y i The tension device which I have shown herein comprises a base member 7 which is adjustably mounted on some part of the,V
machine preferably. as is shown, on the traversing rod 8. .y The yarn 2 is drawn from the bobbin l'through the notch orguide 6 on the outer edge of the base member 7 and` thence between the surfaces of two rotatable disks, the resistance which they offerto rotation imparts a tension to the yarn. The lower disk 9 made of thin flexible metal is rotatable on a bearing 10 formed in the upper surface of the base member 7. The upsage tothe floor below. v Additional tension to the yarn may be had per disk 11, superimposed on the lower disk 9, is slidably and rotatably mounted on a pin 12 whose axis is at right angles to the upper face of the base member 7. Thevpn 12 is fastened to the bracket 13 which is in a stationary relation with the upper surface of the base member 7. The positionof the pin 12 is such that the centre of rotation of l the upper disk 11 is offset lfromthe centre of rotation of thelewer disk v9. This ec- *centricity ofthe centres of rotation between the disks is an essential factor in eecting yarn in its passage between the disks. -To prevent the matter that is thus removed from the yarn from accumulating and obstruct-ing the motion of the disks the lower disk 9 is provided with ya centrally located circular aperture 14 registering with a circular aperture 15 in thebase member 7 through which the waste matter finds aV pas-- by the usev of one or more'weights 16'- slidably and rotatably mounted on thepin 12 and exerting pressure by their weight on the top of the vhub of the disk 11. f
To facilitate the threading .of the'yarn between the, surfaces of the disks the upper disk has upwardly flaring edgeswhich provides a crevice between the surfaces of theV disks into which the yarn falls from the in- Y clined end 17 ofthe bracket 13.
I claim: l A yarn tension device comprising a base,
` a circular aperture in the base, a disk rotat- .to the upper face of the base and offset from the centre of the aperture in the first disk, a bracket in stationary relation with the base and supporting the pin, the second disk rotatably and slidably mounted thereon, a
notch in the base guiding the yarn betweenH the surfaces of the two disks, and an inclined member to facilitate the threading of the yarn.
In testimony whereof, I have signed this specification.
HENRY A. OW'EN.
