IMPROVEMENT IN LOOM.

TO`ALL WHOM IT MAY OONCERN:

Be it knownthat we, JAcoisv SILBERMANN and Gusrnv Unenn, of thefcity and State ofNew York, have invented,lmade, and applied to use, a certain new and useful'lniprovement in WearingfFabrics of Varying' Widths; and we do hereby declare the following to be a full', clear, and exact description of said invention,` reference-'being had to the annexed drawing, making part ot' this specification, wherein-#- v Figure 1 is-a rear view of the loom, showing our improvement, part of the fra-'me being removed, and

Figure 2 is a longitudinal section of the same. l

Similar marks of reference denote the sarne'parts.-

The object of our invention is to weave -areontinuous fabric that is varied in width asv the weaving progreses, and'to eiect the saure without the aid of jacquard-mechanism, and without any portion of the .warpthreads beingsubsequently cutout; i

Oar invention `is primarily intended for weaving neck-ties,- in which the middle portion is narrow, and, the ends gradually widened, so that thenarrower part of said neck-tie may pass aroundl the back of the neck,l and the wider ends be tied together, but oursaid improvement may be applied to weaving any article of varying width to which it may'be'adapted. i

The nature of our said invention consists in areed, with diverging plates vset so as to be raised or lowered in respect to the fabric, in combination with mechanism that raises and lowers said reedin the lay as the weaving? progresses, and also 'causes the diverging reed to'occupy the properJ p osition'inrespect to the divergingwarps passing from the heddles to the fabric, so that there will not be undue strain or wear upon said warps.

In the drawing, a represents the loom-frame; Z, the swords of the lay, hung from thejoints 2; c is the v whip-roller; d,'the breast-beam or roller and e the'point at which the'heddles are applied to the warps. These i parts beingiwell known, and of any ordinarycharacter, doirot require lfurther description, fis the diver-ging reed, set in a frame, z', that' slides in the vertical frame k, o f the lay, andgg are connecting-rods from the frame c to cranks z, upon the shaft Z, that is suspended along the under part of the lay-frame: Neanone end of the shaft l is a crank, m, that has a link, n, connected toA a bent lever, 2J,l on which is a roller, o, in contact with the cam q. r is a spring, keeping the roller o into contact with the cam q, and s is a connection from the lay to .the lever t2, on which is a pawl,'t, to the? wheel t1, that has a pinion, u, gearing with the wheel v, that is connected to the cam q.

The parts are so timed that the cam g willtmake one complete revolutionin weaving each complete article or pattern, and thev cam itself` is to be shaped to produce the desired width of fabric at the proper place. Thus when the roller o rests on the part 12 ofthe cam q, .the link will have swung to the point 4, and allowed the diverging reeds to 'descend-as the laycomes back, thus bringing a. wider portion of the reed down to the line ofthe warps, as that reed comes back to where the warps are wider apart, by the heddles, and in coming for# ward again to beat up the lling, the reed will be lifted by n, and the fabric be narrow. As the cam g turns ,and thevportiou 5 moves the end, 4, of said lever j), in the direction ofthe red arrow, theflink n hangs more nearly vertical, and' does not lift the reed so much, hence the weft will be beatenup by a wider part ofthe reeds, and be correspondingly wider; thus`the fabric can be woven narrower from a wider portion,'or the reverse, and the shape of the cam gis such that the inereaseor decrease of width will occur at the proper time; and it will be 'apparenti that the cam g might have `two or more projecting points, to produce. a corre sponding nurnberroi` variations in the widthof the fabric each complete revolution of the cam q.

The fabric woven vmay be of one thickness, or it may be woven double or tubular, the heddles and shuttle being controlled and moved in the manner 'well known for such characters of weaving. A number of diverging reeds may loe-mounted in lone lay,so as to weave several pieces simultaneously.

What we claim, and desire to secure by Letters Patent, is

Il.A A reed, supported in slides in the lay, in combination with mechanism, substantially as described, that gives an end movement to said reed, each reciproeation of the lay, in order that the wider portion'of the divcrging reed may como into the warps whorcthey staudwvidcl' apart near the l1edd1cs,f0r the purposes and. as sret forth. l

2. The cam q, lever p, 1h11( n, :md shaft Z, ,01 its equivalent, vin combination withthe lay and divcrgng reed, ttcd t0 slide in the lay, and operate in the manner and for the purposesset forth.

In Witness whereof, wp have-hereunto set our signatures, this 20th day of December, 1867. JACOB SILBERMANN,

' GUSTAV UNGER.
