A tension ing the cloth a pair of similar devices will be member 31 is arranged below the rolls 14 and 15 used, said devices being disposed, respectively, to and is mounted for pivotal or swinging movement engage the opposite side edges of the cloth as it on a shaft 32 secured to the base, as at 33. The 75 is being fed. In the drawing only one device is member 31 is held in place on the shaft by a nut illustrated and will be hereinafter described. The 34. The member 31 is in the form of a curved device will include suitable means for attaching or arcuate plate, or, in other words, the member the same to the machine with which the device is curved in profile. The member 31 is substanworks, such means being shown in the drawing, tially triangular in shape and has a curved edge so consisting of a plate 10, which carries suitable 35. A cloth guide in the form of a rod 36 is sefastening elements or bolts 11 to bolt orsecure cured to the plate 10, as at 37, in relation to the the same to a selected part of the machine. A tension member 31, and said rod 36 is curved comtop cloth-guide plate 12 is secured to the plate plemental to the curved edge of the tension .30 10, as at 13, and extends laterallytherefrom, the member 31. The shaft 32 on which the tension upper and outer edge of the plate being well member 31 swings, is disposed parallel to the axis rounded so that the cloth may readily pass over of the rolls 14 and 15. The rod 36 has a terminal or be guided by the plate 10. Use is made of a 38, which is beveled, as at 39, to readily accompair of cloth-feed and guide rolls 14 and 15, which modate the cloth. Means is provided to cause the 35 cooperate with each other to feed and guide the plunger 29 to move against the action of the cloth. The roll 14 is mounted to rotate on a fixed spring 30, to allow the mounting 19 to swing and axis provided by a shaft 16 secured at one end, the roll 15 to move away from the cloth when the as at 17, to the plate 10, and extending laterally cloth under abnormal tension exerts pressure on with respect thereto. The roll 141s held in place the tension member 31, causing movement of 49 on the shaft by a nut 18. The roll 14 is freely the latter. This result is accomplished most satrotatable on the shaft 16 and is made of metal, isfactorily by reason of the cloth passing between preferably brass. A mounting 19 is supported the curved edge 35 of the member 31 and the for swinging movement on a shaft 20, secured, curved rod 36, in conjunction with the abnormal as at 21, to the plate 10 and extending laterally tension on the cloth. The said last means con- 45 therefrom. The mounting 19 is freely swingable sists of a rod 40, having one end secured to the on the shaft 20, The roll 15 is rotatably suptension member 31, as at 41, and its opposite ported in the mounting 19 on a shaft 23, whose end having spaced beveled members or collars 43 opposite ends are received in slots 24 in the fixed thereto. The rod 40 extends through a hole mounting, the shaft being held against displacein the bracket 26. A lever 44 has a fixed fulcrum 50 ment by washers and nuts 25. The axis of the 45cm the bracket 26, said fulcrum-45 being disshaft 20 is parallel to the axis of the shaft 23, posed at one end of the lever, and the opposite and the former is disposed above the latter. It end having ahole therethrough to receive the rod will be apparent that the roll 15 is adjustable as to, so that said end may be disposed between the applied to the mounting 19 and removable theremembers or collars 43. The lever also has a hole i from. The roll 15 consists of a core having a or slot to accommodate the plunger 29. The

plunger has a member or collar 46 fixed thereon to cause the plunger to move in response to the operation of the lever.

In use the device is disposed so that the axes of the rolls 14 and 15 are disposed at an angle with respect to a horizontal plane. The cloth C is passed between the rolls l4 and 15 and also between the curved edge 35 of the tension member 31 and the curved rod 40. The roll 15 will be urged by the spring 30 in a position to cooperate with the roll 14 to feed and guide the cloth downwardly, as indicated by the arrow in Fig. 2. When for any reason the cloth is under or is subjected to an abnormal tension, or in other words, when the cloth is tensioned or stretched causing a reduction in its width, the tension member 31 will be subjected to pressure by the cloth, causing the member 31 to swing, and through the intervention of the rod 41 and lever 44, cause the plunger to move rearwardly. This will withdraw pressure on the mounting 19, thereby allowing the roll 15 to yield from its cooperative relation with respect to the roll 14 so as not to act on the cloth C. When the cloth has regained its normal tension and width, pressure will be withdrawn from the tension member 31, and as a consequence the spring 30 will function to cause the plunger to bear on the mounting 19, and thus move the roll 15 toa proper feeding and guiding relation with respect to the roll 14. The spring 30 also will cause th tension member 31 to bear against the cloth, through the intervention of the collar 46, lever 4 1, one of the rollers 43, and the rod 40.
