SPECIFICATION forming part of `Letters Patent No. 509,339, dated November 21,1893.

` Application filed Julyl, 1892. Serial No. 439,978. (No model.)

To allwhom it may con/cern.:

Be it known that I, GUsTAvE C.-VoIGT, of Waukesha, in the county of Waukesha and State of Wisconsin, have invented new and useful Improvements in Loom-Qhuttles, of which the following is a description, reference being had to the accompanying drawlngs, which are a part of this specification.

My invention has relation to improvements in shuttles particularly adapted for use in connection with looms for the weaving of rag carpets. The shuttles usually employed in looms of the above character require considerable la-V bor i-n order to properly arrange the weft roll therein, many of the forms of which I am the shuttle during the progress of the shuttle through the shed. In unwinding from a shuttle of this character considerable difficulty is experienced owing to the resist-ance offered by the rough material, and in consequence the employment of a heavy shuttle box is required in order to keep the shuttle in its place upon the track. Other makes of shuttles also employ tin boxes which are placed within the shuttle, with the consequence that the weaver 1s compelled to provide himself with a numexpense and labor.

In order to obviate the difficulties above pointed out, I provide a construction of shuttle as will be hereinafter more fully explained in the specification and shown in the drawings, in Which- Figure 1, is a plan View of the shuttle. Fig. 2, 1s a longitudinal section on the line 5--5 of Fig.` 1. Fig. 3, is an' inverted plan View of the shuttle, and Fig. 4:, is a transverse section on the line 7-7 of Fig. 2.

Like numerals of reference indicate like parts throughout the several views.

Referring to the drawings, the numeral 14 indicates my improved shuttle body of the usual contour, and provided with a cavity or chamber 1,5, extending through the bottom of the shuttle body. This cavity is lined with a thin sheathing 16 extending up the sides thereof, and also constituting-the bottom of the cavity or chamber. The sheathing isV formed with a series of punctures or indentations 17, which, when the rags composing the weft of the carpet are inserted therein, .tend

tobold the same in place an ping thereof.

The numerallS indicates a pivoted bail; which when the rags are being insertedk is thrown to one side, and then subsequently brought to a central p0sition,which not only has the effect of retaining the rags in place, but, also, prevents protruding of the same and consequent rubbing of the rough material upon the Warp, during the passage of the shuttle through the shed.

In the usual construction of shuttles, the aperture-through which the end 0f the weft is passed is arranged upon the side thereof. In my form, I prefer to construct an aperture 19, which runs vertically from the top of the shuttle through the bottom, said aperture having a branching aperture 2O running at right angles inward, and communicating with d prevent slipthe longitudinal cavity of the shuttle.

Practice has demonstratedthat in shuttles provided with a lateral aperture the liability of the shuttle being dragged off its track by the lateral pull exists to a great extent. By arranging the aperture so as to extend through the top of the shuttle, this difficulty is entirely obviated, and the weft maybe passed from the longitudinal cavity through the branch aperture 20, into aperture 19, and thence upward in said aperture through the top of the shuttle.

In Figs. 2, 3 and 4, the bottom of the shuttle is shown as provided, upon one side, the outer with relation to the reed, with a Wire track 2l. This track bears directly on the bed or race, and has. a tendency to -tilt the shuttle slightly toward the reed, thereby more eectually keeping said shuttle to its proper position on the bed.

The great advantage possessed by a shuttle constructed in accordance with my improved plan, is that the rags are permitted to be readily pulledfrom the shuttle during its progress through the shed, which is not the case when the rough material composingthe weft is compelled to be unwouud from a spin- Vdle or bobbin arranged Within the shuttle.

As is Well known, the rags which go to make up the weft of a rag carpet are composed of cloth of any material cut up in narrow strips, diering from one-half inch to one and IOO one-halfinches in Width, these pieces being not often longer vthana foot and-.sewed together to form a continuous weft. It will thus be seen, from the nature of the material, that the same possesses a Very uneven tension and consequently an uneven pull is eX- erted on the shuttle; and from vthe Jllatter yto= the selvage, a tine piece of the same weft thread of course leaving the shuttle with less resistance than a heavy piece, and as this sometimes gives a sudden jerk on the shuttle, when the latter is onits travel through the Warp, it would naturally have a tendency to throw the shuttle off the'track Yifthe weft passed out of the shuttle on the side thereof. By -arranging-theweft aperture .inI-the'top, howeverythe tendency -is to lift the shuttle, and the weight of the same is sufticient'topass -thevheavy pieces out` withoutdisturbing 4the run v'of theshuttle. f' Having-thus'described my invention,fwhat Icl'aim'fandfdesire torsecure byiLet-ters Patent,is-
