'rENsIoiv nEvrcE.
`Appnnanon mreafrune as, i924', sel-iaino; 721,800.
To all whom t may concern.'
Be it known that I, JOHN citizen of t-he United States, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented cer` tain new and useful Improvement-s in Tension Devices, of whichr the following, is a specification. v'
The present invention relates to feeding mechanism 'for vthread or` yarn, and'more particularly to a means for maintaining a uniform tension Vupon the thread.
Some of the objects of the present invention are to provide an improved thread tension device; to provide a tension device for thread which can be accurately adjusted to proportion the tension in accordance with the strength of the thread or yarn passing through the device; to provide a tension de vice which maintains a uniform tension upon the thread and prevents the thread from working out of the device during the feeding operation; to' provide a tension device having a range of tension adjustment corresponding to the range of the strength of threads ordinarily employed; to provide a thread tension device having a pluralit of thread pressure means, one or more of w ich can be caused to operate upon a thread according to the tension desired; and to provide other improvements, as will herein after appear.
In the accompanying drawings, Fig. 1 represents a perspective of one form of tension device embodying the present invention; Fig. 2 represents a longitudinal section of the same showing the thread lengaging surfaces in partially closed position; Fig. 3 represents a transverse section of the device.
Referring to the drawings, one form of the present invention consists of a base block 1() which is provided with apertured ears 11 by which it is secured to a Suitable support in operative relation'with respect to the machine with which it is used. This block 10 is provided with an open slot 12, having oppositely disposed beveled sides 13 in order to form an interlocking joint with an insert 14, which is preferably of porcelain or some like material which forms a substantially frictionless surface. It is this insert 14 which supports the thread as it traverses the tension device, and in the pres-l face formed by 4a pluralityof substantially G. ALLEN, a.
\ /shaped corrugations 15 which project a suitable distance above thev top edge of the.'
block'10. A thread discharge opening 16 is formed in the end corrugationof the'insert 14 to direct the thread to the point of use.
superposed one upon the other. This insert' 17 is likewise of porcelain or other material which wlllproduce a minimum! of friction Y* AIn order-to place a tension upon the thread to a thread passing across its surface and.`
.varying the tension upon the thread, theinsert 14 is provided with a plurality of Vthrough guide openings 24, 25, 26, 27 and 28, which are respectively located in the valleys between abutting corrugations 15 of the base 10 and all of which open through a commonslot 30 in the block 10. In the operation of the device, the thread 31, which is to be placed under a predetermined tension, is inserted throughA one of the through guide openings, for example 26, and then carried transversely of the corrugations to the discharge guide opening 16. lWhen the thread is so located, the closure part 18 is lowered and seats of vits lown weight upon the lower insert 14, and in taking this position five pairs of'opposing surfaces engage the thread 31 and actas a drag or brake to its movement through the device. applied tension is proportional with respect to the strength of the thread which is being drawn ythrough the tension device and is This never great enough to break the thread but is enough to maintain a continuous uniform tension lupon the moving thread for the purpose. ntended.=y Vhere alu-inimmn Otten-a S1011 1s requrred upon the Ythreadyrt' Wrllhe inserted through the guide opening 24 and brought. :over the Aendv Leorrugaton, andY but; v

Having thus described my invention, I cla-im; f f
