' Application September 26, 1946, Serial No. 699,431

The present invention relates to new and useful improvements in looms and more particularly to a warp tension attachment therefor.

An important object of the present invention is to provide a simple and practical warp tensioning attachment for looms of small size which eliminates the necessity of using a. warp beam thereby saving time in the warp preparation and lowers the cost of the loom construction.

A further object of the invention is to provide an attachment of this character of simple and practical construction, which is efflcient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had tothe accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a fragmentary side elevational view of a loom showing the warp tensioning attachment in position thereon.

Figure 2 is a front elevational view.

Figure 3 is a top plan view,,and Figure 4 is an enlarged fragmentary sectional view taken substantially on the line 44 of Figure 2.

Referring now to the drawings in'detail wherein for the purpose of illustration 1 have disclosed a preferred embodiment of the invention the numeral 5 designates the rear vertical beam of the loom frame and 6 and 'l the upper and lower longitudinal beams, the rear ends of the beams 6 being connected by an upper transverse beam 8 while the rear ends of the beams I are connected by a lower transverse beam 9.

A conventional form of comb I is secured in a horizontal position to the beam through which the yarn l 1 passes in an upward direction forwardly to the harnesses and other conventional parts of the loom designated generally at I2.

The yarn ll passes over a transverse block l3 secured to the longitudinal beams 6 adjacent the rear ends-thereof, the block having a groove M in its upper surface.

A tension roll is shown at 15 which is seated in the groove [4 with a slight clearance therefrom, the yarn passing under the roll.

A cord or other flexible member 18 extends over each end of the roll 15, one end of the cord being attached to the vertical beam 5 by means of screw eyes or the like II, the other end of the cords being attached to the upper ends of 65 2,329,374

2 Claims. (Cl. 139-97) coil springs I8 which have their lower ends secured to the lower longitudinal beams I. The block l3 may be provided with openings l9 through which the cords l6 freely pass.

In the "operation of the device the yarn ll passes upwardly through 'the comb Ill which straightens and delivers the yarn evenly between the tension roll l5 and the grooved block l3, the springs l8 exerting a desired tension on the yarn.

In view ofthe foregoing description taken in conjunction with the accompanying] drawings it is believed that a clear understanding of g the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by'the spirit of the invention as herein described and the scope of the appended claims.

I claim:

1. A warp tensioning attachment for looms comprising a grooved block over which strands Ofyarn are drawn, a roller seated on the block, a flexible member extended over the roller and slidably extended through said block, and coil springs anchoring the flexible member to a part of the loom to yieldably urge the roller in the groove.

2. A warp tensioning attachment for looms comprising a grooved block over which strands of yarns are drawn, a roller seated on the block, a flexible member extended over the roller and slidably extended through said block toyieldably maintain the roller seated in the groove of the block.
