Definitions

• This invention relates to improvements connectedwith or applicable to tension imparting or clearing mechanism used on machines for dealing. with yarn, thread, and thelike.
• said tension devices means which insure that the yarn is automatically directed between the rotatable devices, that is, by the mere pressing down of the yarn between co-acting guides, the same is directed lIltO- position exactly ready for entrance between the rotatable devices, with result, that, immediately the pull or tension comes on the yarn, the same necessarily passes intoposition and between the rotatable devices which are to exercise the clearing and tensioning effect.
• the object in view can be carried out by various simple devices, as for example, by using oppositely disposed inclined planes one front and the other back of the tension device, the planes deflecting the yarn and throwing it in exact alinenient with the entrance level at, which the meeting faces Specification of Letters Patent.

• Fig. (3 is a detail view of a modified form of'rear wire.
• the cast-iron bracket a is adapted tobe fixed to a railor support such as b and is held by a pinching screw a or otherwise.
• To the bracket (in is attached a slotted steel guide plate 0 and said. bracket (1.
• the bracket has also a cast projection or upstanding portion a and is bored for the beai-ingpin e to which is fixed the lower disk hich preferably has a shallow central its upper face. Resting upon tl ie' lower disk f is the upper or loose dished disk 9 which is adapted to receive weights or washers g. I. find that for the purpose of iy invention, wire deflecting devices serve well and these I preferably apply to or carry from the cast-iron brackets. In thecase of ascending yarn, I use a wire device which has an upright limb h and is then bent downward and forward, as at 71, to produce an inclined directing plane.
• the upright limb IL- is fixed in a hole a in the cast-iron bracket a, and held by a pinching screw if, or otherwise, and, the lower end of the inclined limb h is bent in, a little at h.
• This inclined limb does not reach down to th'ecastpression on iron bracket 0, but terminates about. the line limb which is. oppositely, disposed 'to the other inclined limb of the first bent wire.
• I show a curved limb i (see more particularly Fig. 5). This limb may be bent or provided witha loop or eye, below' whichthe yarn can pass to prevent lifting of the upper-disk. I have not however found this necessary.
• the wire of the limb o'r -loop i is bent and continued downward so that the complete guide .can be fixed by pushing the two ends into holes aa in the cast-iron bracket as shown.
• I may produce both the yarndirecting planes from one length of wire or in the form of a complete device readily attachable to the cast-iron bracket.
• My invention includes directing inclines
• the yarn isshown as passing upward, then through the tension motion and over the bar or ledge a and around the post constituted by the wire i to ,an ordinary drop wire j and then upward again, but the manner of directing the yarn would vary "e'ry considerably.
• a yarn tension device having a bracket
• a slotted steel guide attached thereto, a for ward bifurcated extension on said bracket having a laterally extending lug, rotatable adjacent tension disksadeflecting guide adjustably securedin said lug in advance of the tension disks and to one side thereof, said guide comprising a wire-having a limb that extends upwardly then downward-and forward and then slightly curvedly inwardly to produce an inclined directing plane terminating in line with the contacting faces of. the disks, a-ncl'a double curved defleeting guide inre ar ofsaid disks, said. guides adapted to throw' the yarn-tangeir;
