SPLITTING ATTACHMENT FOR LOOMS.

Specification o1 Letters Patent.

Patented July 24., 191 '1.

To all whorn it may concern;

Be it known that I GEoRon'CHAMPoUx, a citizen of the United states, residing mon Falls, county of Strafl'ord, State-of New Hampshire, have invented an Im rovement in- Splittin Attachments .for ms, which the 511 tion with the-accompanying drawing, is a specification, like characters on the drawing.

re resenting like parts.

his invention relates to a device attached or splittin the. cloth directly. behind' .the ell into'a pluralityof i StliESf .Such attachment may act to cutthe clot when-it is woven in the usual manner or when it'is woven in such a manner as to provide central selvage strips.

The object of the invention is to provide an attachmentof this character which shall be simple andeflicient in its action and insure 'the maintenance of the cloth in contact'with the cutting edge. a

' Another object of the invention is to provide a ciitting blade and a cooperating toothed roll mounted .opposite the cutting edge of the blade and acting to maintain the cloth in contact with said cutting edge.

These and other objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings illustrate so much of a loom as is sufficient for a disclosure of the present invention. The attachment may be associated with an kind of loom and hence the mechanism 0 the loom itself forms no particular part' of the invention.

'For purposes of illustration the breast beam, sand roll and take up roll of an ordinary type of loom are illustrated, being associated with a preferred form of the invention.

In the drawings,

Figure l-is a side elevation partially in cross section of the breast beam and immediately adjacent parts in a loom with an attachment embodying. the present invention in position and showing the fabric being woven;

Fig. 2 is a.to plan view of the construction shown in ig. 1, the fabric being illustrated as being woven with a center selvage;

Fig. 3 is a side elevation of the rearward end of the attachment shown in Fig. 1;

fa somewhat different form 0 at Sal-v of owing description, in connecbehind the fell.

Fig. 4 is a view similar to Fi 3, showing f the attachment;

-5 is a view in cross section taken on .the line 5-5 of Fig. 4.

In the ordinary type of item a breast beam 1 extends across the front of the loom between the side frames. In the rear of the.

breast beam is located 'upon the shaft 2 the sand roll 3 which is positively driven and acts to draw the woven cloth ,through the loom. From the sand roll the woven cloth passes over an idler 4 to the cloth roll 5 upon which it is wound. In' 1 the fell of the cloth is indicated at 6.

The cloth may be woven in any usual and suitable manner and may be of a uniform character of weave throughout, the splitting attachment being em loyed in this case to split the woven cloti into a strips of the desired width. 1' the cloth may be woven as indicated inFig. 2 with one or more longitudinal strips 7 iar weave to form a sort of selvage, the splitting attachment acting in this case to split the fabric centrally of the strip 7,- thus leaving a selvage at each of the opposite split edges.

The splitting attachment illustrated is secured to the breast beam of the loom and projects rearwardly over the cloth directly For this purpose a bracket 8 is shown secured by a screw 9 or in an other suitable manner to the breast This bracket projects rearwardly slightly above the plane of the clot Near its rearward end the bracket 8 isof a pecul-- lurality of provided with 'a vertical transverse aperture 10. A cutting blade 11 has its shank 12 located in the aperture 10 and is adjustably secured in place by a set screw 13. By reason of .this adjustment the cutti blade may be raised or lowered to present'its ed e in pro er cooperative relation to the perip cry 0 the p ane of the cloth and in cooperative relation to the toothed roller hereinafter described. This cutting blade is provided with a sharp cutting ed e 14 and the blade is so shaped and moan that the cut ting edge 14 extends at an acute angle across i the plane of the cloth and in the direction of the warp. The cutting edge may be a she straight edge such as an ordinary kni e edge, as illustrated in Fig. 3, or this edge may be serrated or provided with fine teeth as in the ease of the edge 15 shown in Fig. 4, the teeth being all cut on one side so that the blade may be easily sharpened by grinding the opposite side.

The bracket Sextends rearwardly beyond the aperture 10 and at its rearward end is bifurcated to present the arms 16 in'which is journalei'l, by a screwjournalpin 17, a roller 18. This roller is thus mounted opposite the cutting edge of the blade and the periphery of the roller is so located with respect to the cutting edge. that it presses upon the cloth, is engaged and rotated by the cloth, and acts to maintain the cloth in contact with the cutting edge. and thus secure the efficient and constant action of the blade to s )lit the cloth.

lrefera ily the roller 18 is provided with peripheral teeth which catch in the cloth 'and insure-the. action-of the roller.

As shown in FigQ-tliind'I-i there is a single cir- 'cumfe r eutial i row' 'lJ of these peripheral teeth wlnleas shown m Flgs. 4 and 5 there are two slightly separated circumferential rows 20 of these peripheral teeth, the two rows being, positioned one at each side of the cutting blade :soth'at the cloth is forced down more or less"at both side's'of the cutti'ngedge-of the blade.

In the op eration of the loom as the cloth isdrawnforwardly it IS drawn against the inclined cutting edge of the blade and thero'ller presses thc'clotll against the edge and insures and maintains the contact of the cloth with the edge so that the cloth is accurately and surely split along the desired line. One or more of these attachments are secured to the breast beam at such intervals as will result in splitting the cloth into the rcifilired number and width of strips.

aving fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a loom, a cutting blade, means for supporting it with its cutting edge extending at an acute angle across the plane of the cloth and in the direction of the warp, and a roller provided with two circumferential rows of peripheral teeth engaging the cloth at each side of, and actingto maintain the cloth in contact with, said cutting edge.

2. In a loom, a. breast beam, a. bracket secured to and projecting rearwardly from said breast beam above the plane of the cloth, a cutting blade adjustably secured to said bracket and supporting the cutting edge of the blade at an acute angle across the plane of the cloth and in the directionof the warp, and a roller journaled' in said bracket and provided with two circumferential rows of peripheral teeth engaging the cloth at each side of, and acting "to maintain the cloth in contact with, said cutting blade.

In testimony whereof, I have signed my name to this specification.

GEORGE CHAMPOUX.
