MECHANISM ron REGULATING 'rHE 'rE'NsIoN' IN MACHINES-110a wmm'ns AND CONVEYING STRIPS or FABRIC AND'SIMILAR GOODS.
Application filed July 26, 1926, Serial 166 whereby the qualityof the material is im-' paired, or the material is wound and conveyed under variable and unequal tension. To avoid the first mentioned inconvenience it has hitherto only been possible to use slow coupling driving devices whereas special speed regulatorssometimes in combination with special driving means havebeen employed to overcome the variable tension.
The object of the present invention is to provide means for always conveying or F winding the material with the same-tension 29 under all circumstances even if the winding or conveying machine, is suddenly started. For-this purpose either the material to be conveyed or wound, or the flexible driving means of the" machine is passed over a swingably arranged feeler device which causes the desired tension of'the material or determines the power necessary for carrying out the working process. This feeler de vice in the following simply called tension lever has a direct balancing effect upon the winding or conveying machine for maintaining a uniform tension bra uniform con .sumption of power. If on account of any obstacle the resistance of the material to be conveyed rises, the tension lever effects correspondingly great uncoupling of the drive so that only such an amount of material can be conveyed as is admissible without raising the tension of said material. Therefore even a quick coupling of such a machine does not cause a greater tension of the material than that corresponding to the adjustment of the tension lever. The conveying of the material is efl'ected with such a speed only as to cause the tension applied to the material'to overcome the amount of the machine and the brake resistance of the holding means delivering the material, or as is permitted by the delivery speed of'the holding 11 means without raising the tension of the material. If the resistance is greater than the adjusted tension; the material towound or conveyed is not moved at all so that a tearing of the material is absolutely 66 prevented.

The machines according to the invention may be provided with any suitable slidingor friction-coupling. In the examples shown brake band couplings are employed. These couplings may beso constructed that the conveyin machine or the winding drum is started w ien' the brake is pulled and automatically disconnected when the brake is loosened, or else the" couplings may be so constructed that they constantly tend to act as long as they are not prevented therefrom bythe braking action of the brake band. Depending upon the kind of coupling used a negative and positive action respectively of the devices comes into cohsideration.
The mode of operation of the machine -will now be described with reference to the accompanying drawing wherein,
Figure 1 is a diagrammatic view of one form of my invention.
' Figure 2 is a diagrammatic view of another formof my invention.
Figure 3 is a detail plan view of a portion of the same.
I The material 1 is fed from the spool 10 over the idler 9 and the direction of travel is such as toefiectually act upon the hereinafter described mechanism according to the tension of the web of material 1. The spool 10 is mounted on a shaft 11 and has a link connection 14 with a drive shaft 13. The drive shaft 13 includes the clutch-5 and a drive pulley 12. A-lever 2 is pivotally connected to a stationary support and has one end arranged to engage the web 1 to be actuated b the latter according to the tension thereo This lever 2 carries a cam 4 coacting with a pivoted arm 7 that is connected by the link mechanism of connector 16 with the band 6--of the clutch. A coil spring 3 urges the, lever 2 into anormal position so that the lever "will be sure to follow the web 1. A- second sprin 8 is arranged to act upon the arm 7, to tion to operate the band 6 through, the connection 16 and thus it may be seen that as the lever 2 swings about its pivot, the spring 8 will act to increase or decrease the engagement of the band 6 with the clutch and thereby controlling the amount of power transmitted to the shaft 11 and spool 10.
In Figures 2-and 3 I have illustrated the web 1 'a's passing'from the spool 10 over \the idler 9 with a portion of its length so arrangedasto operatively engage one end diaw the same in a direcof the lever 2 This lever 2 is pivoted to' a stationary support and is urged toward the material by the coil spring 3 In this par-, ticular case the arm 7 B has one end pivoted to a stationary support and the other end connected to a spring 8 the brake band 6 has one end secured to a stationary support and its other end connected to the arm 7 to draw the band into tight engagement with the clutch 5 when the spring 8 is allowed tocontract in a manner now to be described. Cam 4 in this particular instance has a relative arrangement to operate and depress arm 7 'when the web of material becomes slack. Thus it will .be seen that in this particular case the braking action on the clutch is in proportion to the tension of the web 1 That is to sayas the lever swings downwardly it will depress the arm 1 7 so as to release theengaging tween the band andthe clutch.
From the foregoing description taken in action beconnection with the accompanying drawing it will be apparent that as the tension of the material 1 increases or decreases, the lever 2 will be swung about, its axle for manipulating the various parts for increasing or decreasing the amount of power transmitted to thefeed mechanism and thus the uniform tension of the material is assured.
The device according to the invention is not to be limited to the conveyance of fabric strips but may also be used vfor conveying and winding cables, wires, threads and the like. Moreover the new device may also be used as a safety device for preventing overloading in the most different stems of power transmission by belts, cab es, chains and similar driving means.
What I claim is:
1. In combination, a drive shaft, web feeding mechanism, a drive connect-ion between the shaft and said mechanism including a friction clutch, a brake band controlling the operation of the'clutch, a, pivotally mounted arm operatively connected to said band, a spring normally acting to force the-arm in one direction, a cam for moving the arm in an opposite direction, and a lever connected to said cam and engaging the web to be operated thereby according to the tension of the web. 1
2. In combination, web feeding mecha msm, driving means therefor mcluding a friction clutch, a brake band having one end secured to a stationary support and passed around said clutch, a pivoted arm connected tothe other end of the band, a spring acting on the arm to draw the band into engagement with said clutch, a cam acting upon the arm to move the same to release the band from the clutch, a lever connected to said cam, and havin a free end operatively engaging the web 1n the travel of the latter.
n witness whereof I have hereunto set my hand. I
GUIDO HORN.
