THREAD-TENSIONING nnvron Application filed March 11, 1926. Serial No. 93,943.
Myinvention relates to thread tensioning devices and has for its object to provide a device of this class which is adapted toeXert a frictional force on a thread, or filament,
passing therethrough, so that thejthread may be drawn with just enough tension to keep it taut. i
My improved. device is particularly characterized by the fact that it is so constructed that the amount of frictional force exerted on the thread can be readily adjusted within very small limits to meet varying conditions of operation- My device is further characterized by the fact that it presents smooth and unbroken surfaces to the thread, so that there is no possibility of a thread becoming accidentally entangled therein the surfaces of the device being so formed that any tendency of the thread to disengage 2 itself from the device as it is drawn there through will be opposed. The above and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying draw ings in which Fig. 1 is a perspective View illustrating the use of a thread tensioning device CID, bodying my invention.
Fig. 2 is a view in side elevation showing the device of Fig. 1 on an enlarged scale.
Fig. 3 is a in Fig. 2.
Fig. 4 is a vertical sectional View along the line 4l4, Fig. 3.
Like reference characters refer to like parts in the different figures.
Referring first to Fig. 1, my device is illustrated as being employed in connection with a spool or yarn package 1, from which it is desired to draw the thread 2 for any suitable purpose, as for Winding on a large spool or warp beam, a portion of which is indicated at 3. When thethread 2 is subjected to a draft in the direction of the small arrows, it is evident that in the absence of any other force acting on the thread, it would tend to unwind loosely from the package 1, thereby creating slack which i would be undesirable if the thread is to be wound tightly on the beam 3..
In order to prevent slack in the thread 2 plan view of the device shown and toinsure that the thread 2 will be wound on the beam with' a uniform tension, niyimproved tensioning device, indicated generally at 4, isdisposed between the spool 1 and the beam 8, and if desired, the thread maybe passed through suitable eyes 5, 5, in
passing to and from the tensioning device 4. a
being evident that my device may be an ployed for many other purposes in whichit is desired to" place a moving thread under a slight tension, as will hereinafter appear.
referring now to Figs. 2, 3 and 4, my device comprises opposed cup-shaped memhers 6 and 7 loosely surrounding a central arbor or sleeve 8 which is preferably made of porcelain, so that itpresents a smooth frictionless surface where it passes through the members 6 and 7. .The sleeve 8 provides a longitudinal opening through which passes a bolt 9, whereby the sleeve may be secured to a suitable supporting bar 10 by means of a nut 11 coacting with the bolt 9. As
shown, the bar 10 provides a recess or seat 12 for receiving and positioning the end of the sleeve 8, although the seat 12 is not absolutely essential.
As previously stated, the members 6 and 7 loosely surround the sleeve 8 and the upper member 7 is maintained in frictional engagement with the lower member 6 by means ofa number of washers 13 received on the sleeve 8 within the member 7. The memhere 6 and 7 are so formed that they are in engagement with each other onlywithin a narrow annular zone determined by the extent of the flat surfaces 14 and 15 provided by the members 6 and 7 respectively. The lower member 6 presents a curved surface 16 surrounding the flat surface 14, while the upper member 7 provides a similar curved surface 17, from which extends upwardly a frusto conical portion 18.
As clearly shown in Fig. 2, the members loo on the thread beyond the device will cause the thread to be held between the opposed fiat surfaces 14 and 15. The thread will therefore be subjected to a frictional force as it is drawn through the device, which results in a slight tension being imparted to the thread as it leaves the device. This tensionainsures thata thread will bewound on the beam 3 uniformly, andiitis evident that when a number of devices are employed for several packages 1, the devices can'be so adjusted as to insure the same tension in each thread.
The employment of a number of washers 13 for each device makes it possible to very closely regulate the frictional engagement of the fiat surfaces H and 15 with the thread as it passes therebetween, thereby adapting the device to meet varying conditions of operation. It is also apparent that the rounded surfaces 16 and 17 will serve to guide the thread between the opposed surfaces 14 and 15 and that there will be no ten- (lency for the thread to disengage itself from the device and become entangled. Furthermore, the conical form of both members 6 and 7 opposes any tendency for the thread to creep either up or down, and actually serves to direct the thread between the surfaces 14 and 15.
I claim:
In a thread tensioning device, a bolt, a porcelain sleeve surrounding said bolt, an inverted cup shaped member loosely surrounding said sleeve, said cup shaped member having its cylindrical surface and its base surface joined by agently curving surface, a second cup shaped memherwith its base resting oirthe base of said first cup shaped member around a narrow annular zone, said second cup shaped member having an upwardly extending hollow portion of trusteconical shape, said l'rusto-conimil surface merginginto the base of said second cup shaped member by a gently curved surface,
and a plurality of weights located inside said second cup shaped Illfllllllfll around the porcelain sleeve, the whole device being readily threaded and oli'ering a resistance to the passage of thread that is determined by the number of weights in the second cup shaped member. the porcelain sleeve otterinc practically no resistance.
