SAMUEL T. THOMAS AND ELIZA ANN EVERETT, ADMINISTRATRIX OF E. EVERETT, DECEASED, OF LAWRENCE, MASSACHUSETTS.

LOOM-BEAM.

Specication of Letters Patent No.

To all whom t may concern:

Be it known that I, SAMUEL T. THOMAS, of Lawrence, in the county of Essex and State of Massachusetts, in conjunction with EDWARD EvERET'r, late of said Lawrence, deceased, have invented certain new and use ful Improvements in the Manner of Making Up a Loom-Beam for Looms, and that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and eXact specification of the same, wherein are set forth the nature and principles of our said improvements by which our invention may be distinguished from others of a similar class, together with such parts as are claimed and desired to ,be secured by Letters Patent.

The figures of the accompanying plate of drawings represent our improvements.

Figure l, is an elevation of my improved loom beam. Fig. 2, is a similar view with the parts differently arranged. Fig. 3 is a central vertical section of the loom beam.

The method hitherto practiced of making up a loom beam consists in warping from a large supplying beam, to the loom beam which admits of no change in the width of the loom beam or in the collection of the yarns or stripes of the same without a corresponding change in the supplying beam. Our improvement consists in warping the yarns from the supplying beam on to sectional loom beams which when placed side by side on a| shaft make up the entire loom beam ready for insertion in the loom. By this arrangement the width of the loom beam can be increased at pleasure and is not as in the old method dependent upon the width of the supplying beam. This manner of making up a loom beam also affords great facilities for varying the arrangement of colors in the loom beam while the width of the stripes can be increased without any alteration in the yarns of the supplying beam. This is done by so placing the sectional loom beams with regard to each other in the loom as to bring the end stripe of one immediately adjacent to a similar stripe of the ne-Xt it being only necessary in thus arranging the sectional loom beams to alternate their direction of revolution while being formed.

a, a a2, in the drawings represents a series of sectional loom beams placed side by side upon a square shaft Z) b. The yarns are first 11,919, dated November 7, 1854.

warped directly on to the sectional loom beam a which as soon as finished is removed from the warping machine and placed upon the shaft Zi. The sectional beams a a2 are formed in a similar manner and placed on the same shaft b b as shown in the drawings. Any number of these sectional beams may be placed upon the shaft b Z2 and when keyed upon the same will form an entire loom beam ready for insertion in the loom. The sectional loom beams a a2 may be so placed with regard to each other in their shaft as to bring the stripes formed by the colored yarns in the same consecutive order as those on the sectional loom beam a as shown in Fig. l, or the sectional loom beam a2 may be so placed with regard to the sectional loom beam a by reversing its position or turning it end for end as to form a stripe of double width in the fabrics as clearly shown in Fig. 2. latter case to reverse the direction of revolution of the sectional loom beam a2 While forming it in order that it may deliver the yarns to the loom in the same direction as the other loombeams. l

From the foregoing description it will be seen that the manner of making up the loom beam of sectional loom beams affords greater facilities for varying the width of the loom beam and for arrangement of stripes or colors than the method heretofore employed as hereinbefore explained.

Having thus described our improvements our claims will be stated as follows:

`What is claimed as our invention and desire to be secured to us by Letters Patent,

Forming the loom beam of sectional parts or beams which when arranged side by side on a shaft form the entire loom beam ready for insertion in the loo-m, by which arrangement the length of the loom beams may be varied and a Variety in the stripes produced by simply varying the relative positions of the sectional loom beams in the loom as hereinabove set forth.
