ALONZO IV. ALLEN, OF PHILADELPHIA, PENNSYLVANIA.
SPECIFICATION forming; part of Letters Patent No. 781,861, dated Februar '7', 1905.
Application filed November '7, 1903. Serial No. 180,148.
In /t// IF/101M it may concern.-
Be it known that I, ALoNzo W. ALLEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Thread or Yarn 'lension Devices, of which the following is a specification.
This invention relates to means to secure an even and proper tension on threads and yarns by the employment of gripping and carrying members composed of a material which presents a smooth glazed surface not easily worn or grooved and not liable to abrade or damage the thread or yarn in its passage under pressure to keep it to a desired tension. \Vhere knots or enlargements occur, there is great liability to fray if the tension members are not pefectly smooth or ungrooved. Heretofore the tension in similar devices has been produced by metallic disks between which the thread or yarn passed and also over the surface of the spindle. \Vith silk or hard thread and yarn grooves are soon out which not only destroy the spindle and disks, but on account of the rough worn grooves causes destructive abrasion and the catching of knots and enlargements in the rough grooves through which the thread or yarn must pass.
By this invention the wearing of the parts and the damage to the threador yarn is overcome and a perfect tension is secured.
The invention is illustrated in the accompanying drawings, wherein similar parts are designated by similar characters of reference, in which Figure l is an elevation view of the disks mounted upon a stand adapted for use on winding-machines. Fig. 2 is a view of the left end of the stand and a disk. Fig. 3 is a Fig. 5 is a view of the 1 6 is an end z:
to a machine using a threador yarn tension, is employed to support a spindle 2, on which are placed a spring 3, disks & 5, a carrier 6 between the disks, a nut 7, and a lock-nut 8 on a thread at the outer end of the spindle 2. A round section-guide 9 is secured movably to stand 1, and a plate-guide '10 issecured to the base 11 of stand 1. The parts just described are similar to those heretofore used for the purpose, with the exception of disks 4. and carrier 6, which in the present invention are made of porcelain, which has so far been found the preferable material for the purpose specitied.
The edges 12 of disks I are inwardly curved to guide the thread or yarn, and at the center of their inner or working faces 13 they are provided with countersinks or recesses II of suiiicient depth and diameter to clear the carrier 6, placed loosely on spindle 2, so that it is free to rotate if the lead of the thread or yarn in its passage produces friction sufiieient for the purpose. A hub projecting from one disk and entering a recess in the opposite disk might be employed; but for various reasons the separate carrier with uniform hubs is deemed the preferable form to employ.
I claim 1. In a tension device for threads and yarns, disks of porcelain having a recess at the central face of each disk, a porcelain carrier within the recesses, and of a diameter and length to avoid frictional contact with the disks recesses, and over which the threads and yarns are guided, in combination with means to mount the disks and carrier for free rotary movement, and means to press the disks together.
In a thread and yarn tension device,a pair of porcelain disks having central recesses within their adjacent faces, a porcelain carrier incloscd by the recesses and freely rotatable therein, in combination with suitable means to mount the disks and the carrier on a machine, .for free rotary movement and means for yieldingly pressing the disks together.
