TENSION EECHANSM.
Application led. .april 18, 1922. Serial No, 555,122.
To @ZZ/017mm t may concern f Be it lrnown that l, JOHN 0. Molnniv, a citizen ot the United States, and resident of l'li/festlield, in the county ot l-ainpden and State ot lilasschusetts, have invented a new and useful Improvement in Tension lili chanisms, or which the following` is a specilication.
ln gravity operated tension devices there is a tendency oi the` weighted tension washers to unduly vibrate and jump away from their coacting surfaces because ot unevenness in the yarn or oit machine vibrations, thereby exerting' a haini'nering action l5 on the threads suiiicient to vary the tension thereon and at times to cut the threads. This is especially true where the devices are used in connection with stop motions.
The object of my invention is to eliminate 2o thisvibratory tendency on the part of the tension washers, by the inter-position ot washers composed of some suitable yielding' material, such as felt, between the tension washers and their weights.
practical embodiment or my invention is represented in the accompanying drawings, in which` Fig. l represents a view in side elevation ot a portion ot a stop motion with my iinproved gravity operated tension device applied thereto, thc parts being` shown in dotted lines in their usual running position7 and in full lines in thei knocked-oil or stopped position.
Fig. 2 represents a detail section taken in the plane of the line llll of Fig'. l. looking in the direction of the arrows. i l
The tension device includes a suitable support l, having a thread contact surface,
4o which support is carried by the swinging arm 2 of the stop motion; from which support uprises a pin 3. A gravity operated thread tension washer e is loosely mounted on the uprising pin 3, in position to coact with the thread contact surface of the support.
A washer 5 of some suitable yielding` niaterial, such for instance as telt, is looselj,v mounted on the pin 3 on top of the tension washer et. @ne or more, in the present instance, two tension weights 6 and 7 are loosely mounted on the pin on top ot' the yielding washer 5. By locating` the washer of felt or other suitable yielding material between the tension washer and weights, the vibration of the tension washer is materially reduc-ed and all tendency of the washer to cut the yari'i by a hammering action, is eliminated. VFurtherinore, the noise incident to the operation ot the tension cevice is practically eliminated. These telt or other yielding material washers may also be produced very cheaply, thereby ensuring' the objects desired in an inexpensive torni.
A threading' guard 8 may be removably secured to the top oif the pin 3 by a screw 9.
lt is evident that various changes may be 'esorted to in the construction, 'lorni and arrangement of the several parts` without departing from the spirit and scope or" my invention; hence, l do not wish to limit inysel'l" to the particular embodiment herein shown and described, but
l. ln a tension mechanism, an clement having` an unyielding thread contact surface, and a gravity operated tension device arranged to coe-.ct therewith, conipiising` a tension washer, a tension .veig'ht, and a washer ot yielding,` material interposed between the tension washer and .veig'ht.
2. ln a tension mechanism, an element having' an unyielding thread Contact surface, and a gravity operated tension device arranged to coact therewith, comprisinzg` a vertically arranged pin7 a tension washer, a tension weight, and an interposed washer or yielding material, all loosely mounted on said pin.
ln testimony, that l claim the foregoing as my invention, L have signed my naine this 25th day or" March, '1922.
