a Our invention relates to fabric attachments for looms. In accordance with our invention, we provide a fabric splittingfelement, which; is 5 adapted for attachment to-the breastbe'amof splitting erally horizontally arranged arm extending over 'a portio of -the fabric passing to the,

sand roll); 'Thevcuttingfelement is arranged-, beneath this generallyhorizontal arm to engage with the fabric and split the same and is carried by the arm. The arm extends over and covers the cutting element, thereby protecting the hands of the operator from con-.

tact with the cutting element. Inclined 1, wings are preferably provided near the cutting element and serve to support the fabric and hold the same taut. so that the cutting.

operation may be properly carried out. The 1 I 3 splitting element as a whole is adjustable longitudinally of the breast beam so-that the fabric may be cut into strips of any desired,

width and any suitable number of splitting v elements may be mounted upon the breast beam depending upon the number of strips into which the fabric is to be cut.

The fabric is preferably woven with a longitudinal strip 10 formed by omitting some of the warps.)

Particular attention is called to the fact that the free or forward end of the arm or strap 20 projects over the blade or cutting element 26, covering the same longitudinally and laterally and extending laterally beyond the blade 26 for substantial distances. The arm thus serves as a guard to protect the hand of the operator from contact with the blade 26.

The attachment is extremely simple, is formed of few parts, is strong, durable, and may be readily adjusted within wide limits.

The operation of the device is as follows:

The carriage 15 is mountedupon the rail 11 and the upstanding rib 14 enters the groove or recess 16. The carriage is moved longitudinally of the rail to the selected adjusted position and the bolts 18 are then screwed up and clamped to the carriage in this selected ition. The inclined wings 22 engage beneath the split edges of the fabric while the blade 26 is supported in an inclined position in advance of these wings to cut or split the fabric, as it is traveling in the direction of the sand roll.

It is to be understood that the form of our invention, herewith shown and described, is to be taken as a preferred example of the size and arrangement of parts, may be resorted to, without departing from the spirit of our invention, or the scope of the subjoined claims.

Having thus described our invention, we

claim covered by the free end portion of the arm.

3. A cloth splitting attachment for looms, comprising a generally horizontal arm, means for attaching the arm to the breast beam of the loom, a depending shank secured to the arm, wings arranged upon opposite sides of the shank and attached thereto to engage beneath the fabric, a bracket secured to the shank, and means for clamping a blade to the side of the bracket.

A cloth splittin attachment for looms, comprising a general y horizontal arm, means for attaching the arm to the breast beam of the loom, a depending shank secured to the arm, wings arranged upon opposite sides of the shank and attached thereto, one wing having a slot formed therein, a bracket secured to the shank and extending below the win a blade engaging one side of the brac et and passing into the slot, and means to clamp the blade to the bracket.

In testimony whereof we aflix our signatures.
