WARE-THREAD PLATE.

1 Application led April 21, 1924. Serial No. 708,046.

To all -zcwm z't may concern.'

Be it known that I, HERBERT V. W. SCOTT, a citizen of the United States, residing at Paterson, in the county of Passaic and State 5 of New Jersey, have invented certain new and useful Improve-ments in Warp-Thread Plates, of which the following is a specilication.

My invention relates to warp thread plates for textile machines; and is not only used for threading-in a warp, but in many cases the. threads continue to run through the plate after both the warp and the plate are placed in the machine. It is not only used in jacquard machines, but is also used for making of warps in any textile 'machine Where a Warp is used, as for instance, in warp knitting machines, broad silk looms, carpet looms, etc., etc.

In textile warping, the yarn is lirst wound on spools, and a large number of these spools are placed on a jack or creel.' The ends of the threads from these spools are threaded through the holes of the warp thread plate which is placed directly in front of the warping mill. Then as the threads are run through the plate onto the mill, they are gauged by the lay-out of the plate holes to conform with the machine uge or cloth 30 count desired. Hence the p ates vary in shape according to the machine with which they are to be used and the number of threads per inch desired. The plate shown in the drawings has 168 holes laid out in six rows on a four inch plate; others might have an equal number of holes laid out in four rows on a six inch plate; while others might have a total of, say, only 80 holes, etc.

The object in view is to provide a plate that will prevent the yarn from being cut by any rough edge or surface. I have found out by experience that silk running at a high speed through holes in a metal plate will cut the metal regardless of its hardness and the grooves and irregularities thus formed, will in turn, abrade and cut the threads.

`Minor obj eets of the invention will appear in the subjoined description. v The inventionconsists in the construction and arrangement of the parts, and the method of assembling the same and,

' e them in rigid relation to each other', as wi be hereinafter described and claimed, refer-- section, on an enlarged scale, showing one y form of eyelet or bushing'as it appears em-' bedded in the plate.

The numeral l indicates the plate,l which is provided with a plurality/ofsuitably arranged holes 2; and these holes are provided 1n turn with eyelets or bushings 3 to take up the wear. A

I have found in practice that porcelain is an admirable material to use in making these bushings, because of its great smoothness andgreat resistance to wear; but I do not limit myself to the use of any one material, either hard or soft, for these eyelets or bushings, using whatever material may be found most desirable to meet any given' case, since my device is not limited to the silk industry, but as already statedis used wlth any textile machine whatsoever where warps are used.

The eyelets are secured in the plate in any ordinary or preferred manner. In practice I have found that mould casting is usually satisfactory. The small eyelets are placed on plus inside the mould, and the molten instal, or alloy, poured in.

'I hese eyelets or bushings are made in any deslred form, that illustrated in Fig. 2 of the drawings 'being a good form. In this form the eyelet is provided exteriorly with an annular swell 3a, so that when the molten metal hardens around it, the eyelet will be soy very firmly held in the plate, which is comparatively thin.

Whenever itis deemed necessary to do so, a little antimony may be added to the metal or alloy (from which the plate is more' often made), to cause the metal as it cools to contract around the eyelets, and in that way grip them very t' htly.

The addition olthe l gives it great stren h for its size.-

To those skilled gd the art,

parent, since inan al1-metal plate, however l los y porcelain plate is very brittle, and e'onse'- quently easily broken; but with my arrangement any suitable material, either metallic or non-metallic, may be used for the plate.

Having now described my invention, what I claim as new and desire to protect by Letters Patent is l. In a device of the character described, a plate formed from molten metal by casting, and having wear eyelets previously formed of a different material, said eyelets being arranged in position conforming to the configuration of the plate to be formed,

1 and cast in the plate simultaneously with its formation, the molten metal being poured around them; whereby the complete eyelet plate is formed at a single operation, and the plate and eyelets are from a practical point of View integral in formation.

2. In a device of the character described, a plate formed from molten metal by casting, and having wear eyelets previously formed of a different material, said eyelets being arranged in position conforming to 'the configuration of the plate to be made, and cast in the plate simultaneously with its formation, the molten metal lbeing poured around them; whereby the complete.

eyelet plate is formed at a single operation,

the eyelets beingy arranged between the planes formed by the opposite sides of the plate, whereby not to project beyond said planes.

3. In a device of the character described, a plate formed from molten metal by casting, and having wear eyelets previously formed of porcelain, said eyelets being arranged in position to conform to the configuration of the plate to be formed, and cast in the plate simultaneously with its formation, the molten metal being poured around them in the plate, whereby to# utilize the shrinkage of the metal in cooling to rigidly secure the eyelets in the plate without the use of cement, the eyelets being of a length equal to the thickness of the plate with their open ends ush with the sides of the plate; whereby to provide a' plate of practically integral construction without projections on either of its faces.

4. In a device of the character described, the combination with a plate having openings therein for the threads, of bushings cast in said openings, said bushings being exteriorly provided with annular swells.

In testimony whereof I aiix my signature.

HERBERT V. W. SCOTT.
