Patented Dec. 23, 1 930 UNITED STATES PATENT OFFICE WALTER CLYDE STEWART, OI GASTONIA, NORTH CAROLINA, ASSIGNOR T0 EMANUEL FROHMAN, OF GASTONIA, NORTH CAROLINA YIARN-TENSIONING DEVICE Application filed June 5, 1929. Serial No. 368,628.
This invention relates to a tension device for textile machinery, and more especlally .to winders, spoolers, and the like in which it is desired to give an adjustedtension to the thread for said purposes.
An object of my invention is to provide a tensioning device for thread and the yarn, in which the tension can be adjusted and in which there iseliminated the possibility of lint and foreign articles lodging in the tensioning device to prevent the proper'opera- 'tion of the same.
Another object of my invention is to provide a tensioning device which is capable of being adjusted to suit various sizes of yarn, and in which the tension can be properly adjusted, and in which there is little possibility of lint and foreign articles becoming lodged in the tensioning device, and preventing the proper function of the same.
Some of the objects of myinvention having been statedother objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of a portion of a spooler frame showing my invention applied thereto Figure 2 is an enlarged perspective view of my tensioning device, and associated parts of the machine. to which it is adapted to be secured Figure 3 is a cross-sectional view through my tensioning device and being taken along the line 3-3 in Figure 1;
Figure at is an end view of my tensioning device.
Referring more specifically to the drawings the numeral 10 indicates the transversely disposed shaft on which the members 11 are adjustably mounted, said members 11 being adapted to hold the bobbin loosely,
said bobbin being indicated by the reference thread goes through the guide member 17 which is mounted on the rod 18 and the thread is then wound on to the spool '19 which is positively driven by means ,of the pulley 20 driven by the belt 21.
My adjusting device comprising the member- 22 which is pivotally and adjustably mounted on the bolt 16 as above described, and this member '22 projects outwardly and has the curved portion 23, with the projecting portion 24 which prevents the tensioning means proper from dropping out of the division in which the same is mounted. A bolt 25 pierces the member 22 and also the member 26, which member 26 is curved as at 27 to engage the tensioning device 28, which tensioning device 28 has the ball 29 mounted therein, and has the downwardly and inwardly sloping ,wall portions 80, in which the ball 29 is adapted to rest. These 'wall portions 30 extend all the way through the member 28, and the thread is adapted to be passed upwardly through this passageway, and between the ball 29 and the wall portions 30. This member 28 has rounded, upward and lower surfaces, and is preferably made of porcelain, and the ball 29jis preferably of chilled steel, and this ball 29 can be varied in size and weightto suit the size of the thread which is beingpassed through the tensioning device,
- This tensioning device 28.has the slot 32 cut in one side thereof with the inwardly slanting portions 83 and 34 so that the thread can be instantly passed into the tensioning device, and due to thefactthat it is held by the winding and spoolingoperation on the opposite side of the'passageway than where the slot occurs, and there is no danger of the thread coming out of the slot except when removed manually by the operator.
In order to adjust the tension under which the thread is held the device may be'adjusted in various positions as shown by the dotted lines in Figure 1, it being evident that as the tensioning device 15 is raised upwardly in the dotted lines which is shown in Figure 1 that the tension will be decreased and the greater tension will be secured when the dev1ce is in the position as shown in full lines.
IOU
It is of course understood that this device can be adjusted in any desired position as to angularity with respect to the horizontal and the dotted lined position shown in Figure 1, is merely one of the adjusted positions into which this device may be placed.
I also find that I can use balls not only of diiferent sizes made of steel in order to adjust the tension for various sizes of yarn, but I also have found that by using balls of various material such as glass, porcelain, and other materials that the tension can be regulated in this manner as Well as by changing the angularity of the tensioning device with respect tothe horizontal.
It is thus seen that I have provided the tensioning device in which the possibility of lint and other material lodging in the device is removed due to the fact that the ball 29 is in a constant whirling motion while the thread is being passed therethrough, and thus all lint is entirely removed from the slot, so that it is impossible for the tensioning device to become out of order on account of lint lodging therein, as occurs in many tensioning devices which has heretofore been used. It is of course evident that whena different size of ball is desired to be inserted into the device, that the member 26 is re-. moved and this allows the member 28 to be taken out and a new ball inserted in place of the one which is in the tensioning device at the time, and then the arts are mounted back into the position as s own in the drawings and the projection 24 prevents the ball from escaping from the device regardless of theangularity at which the device is adjusted.
In the drawings and specification I have set forth a preferred'embodiment of my invention, and although specific terms are employed they are used in a' generic and descriptive sense only, and not for pu oses of limi tation, the scope of the invention being set forth in the appended claim.
I claim- A tensioning device having a funnel shaped passageway with a ball-member in said passageway, and means for adjusting the tension of thread which is adapted to be passed therethrough. v
In testimony whereof I afiix my signature.
