Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed April 17, 1911. Serial No. 621,455.

To all whom it may concern.

Be it known that L FREDE-RIOK BENZ, Jr, citizen of the United States, residing at Haledon, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Batten Structures for Narrow-WVare Looms, of which the followin is a specification.

My object in and by the present invention is so to construct the batten-structure of a loom of the narrow-ware class as to secure any of several alternative advantages, to wit, either greater clearance between each shuttle and the warp shed, or, the amount of such clearance remaining unincreased, the employment of shuttles having either larger bows or projecting portions (and hence greater capacity for weft or filling), or increased contact between each shuttle and the block or other support in which it runs.

A further object of my invention is so to construct the framework whereby the shuttle blocks are supported or held in position, and so to combine said framework with the shuttle blocks, as not only to facilitate the positioning of the reeds but keep the several shuttle blocks absolutely true to the position in which they are originally set, that is, so that their shuttle guiding grooves are as perfectly alined with each other as if the whole series of grooves were formed in a single strip or piece.

In the accompanying drawing the single View is a vertical section of the improved batten structure, the harness and a warp shed appearing in elevation and a guide for the goods appearing also in section.

In said drawing the batten structure appears in its rearmost position, leaving a space between the rearmost part thereof and the harness f. While it is the object of the loom builder to reduce this space as much as possible, in order to secure compactness and for other reasons, it must not be less than a certain amount, else the batten will contact with the harness and wear the same.

I-Ieretofore the bracing strip g was secured against the backs of the uprights h, in turn secured to the backs of the batten proper z and shuttle blocks j, and was the part from which (to wit, from the back thereof) the measurement was taken for the preservation of the necessary distance between the harness f and the portion of the batten-structure which most nearly approached the harness. I have ascertained that by re-arranging the said bracing strip and the uprights, so that the former is disposed forward of the latter, any of the advantages which I have above enumerated may be obtained. Thus in-the drawing the bracing strip 9 is shown forward of the uprights it, Which are metallic plates perfectly flat throughout, their positions being transposed relatively to the old arrangement already described, and the backs of the shuttle blocks being recessed .to receivesaid strip. By this transposition of the strip and uprights, the batten proper and the shuttle blocks are brought nearer to the harness by a distance precisely equal to the thickness of the bracing strip.

It will be understood that the apex of the shed j must stand a given distance from the harness f (or from the guide 70 on the 'breast-beam-not shown, over which the woven goods Z passes). Therefore if the shuttle body a and the shuttle bow m remain of the same dimensions as heretofore, appreciably greater clearance will be left between the warps of the shed y" and the bow of the shuttle. Or, if this clearance remains the same, then either the bow or the shuttle may be made larger (so as to accommodate a filling carrier of greater capacity than before) or the body of the shuttle may be made of greater forward to rear dimension so that, upon correspondingly augmenting the forward to rear dimension of the shuttle block, the contact surfaces between the shuttle body and shuttle block will be correspondingly augmented, increasing the Working life of both of them.

It will be observed that my construction involves these additional advantages: The framework, comprising the bracing strip and plates or uprights 71 because the bracing strip, as shown, is let into recesses at the back of the shuttle blocks, is practically interlocked with the several shuttle blocks and bears down upon the subjacent surfaces of said recesses, so that when the said framework is secured to the shuttle blocks and batten proper each shut-tle block must retain permanently the exact position to which it is adjusted by the batten builder; therefore the several grooves in the blocks retain permanently that precise alinement with each other in which they are initially set, insuring the true running of the shuttles in their grooves and the elimination of wear which, because it is irregular or not uniform throughout the entire length of the bearing surfaces of the shuttles and grooves, results in undue vibration and noise. Again, the backs of the bracing strips and batten proper being vertically alined with each other, they form with the uprights or plates reed pockets or recesses to which the reeds may be conveniently introduced from the rear, to be then secured to the backs of the bracingstrip and batten proper, instead of, as in'the old construction, having to be introduced from above down in front of the bracing strip and back of the batten proper.

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

The combination of the batten proper, shuttle blocks arranged thereon, the batten proper and shuttle blocks having vertical rear faces flush with each other, and the backs of the shuttle blocks having horizontally alined recesses extending across them, and means for securing the shuttle blocks to the batten .proper including a framework interlocked with the shuttle blocks and comprising flat upright plates bearing against the backs of'the batten proper and shuttle blocks and a bracing strip arranged against the front faces of and connecting said plates and received by and bearing down upon the lower surfaces of said recesses, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
