H. w. UNGER YARN INSPECTING MACHINE Filed July 9, 1921 Patented June 26, 1923.

httatfia HERVEY W. UNGE PJ, OF FALCONER, NEW/V YORK.

YARN-INSPECTING MACHINE.

Application filed July 9,

T all whom 2'25 may concern:

do it known that I, llnnvnr W'. Unonn, a citizen of the United States, residing at the village of Falconer, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Yarn-Inspecting Machines, of

which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to mechanism for yarn millsand particularly to yarn inspection; and the object of the improvement to provide a machine in which a number of yarn ends may be conducted from the creel frame to ayarn roll or rolls and caused to travel over a series of different colored inspection boards and rewound or made into hanks or' skeins', the different colored surfaces of said boards being placed at the best angle for reflecting the light through the many strands of yarn as they run freely over said boards, t ereby giving the inspector opportunity to seeall imperfections in the yarn and correct the same; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspective view of the yarn inspection machine showing the preferred arrangement and construction of the same. Fig. 2 is a' top plan view of i the inspection hoard rack showing half of the-boards turned with theblack side toward the operator, and the other half with the white or light colored side, to best reveal the imperfections in the different colored threads when inspecting. the same; and Fig. 3 is a side elevation of the inspection board rack as shown in Fig. 2, showing the ratchet wheels, one to each board, for adjustably holding the same at the desired angle; and Fig. 4 is an elevation of one of said inspection boards showing the metal capped ends and manner of rotatably mounting in the side rails, the side rail being shown at one end with a portion broken away to show the axial pins on the capped ends of said board. Fig. 5 is a perspective view of one of said metal caps for said board with the ratchet attached thereto; and Fig. 6 is a lengthwise sectional view of the metal cap as shown in Fig. 5, showing the preferred integral attachment of the ratchet wheel to said metal cap; and Fig. 7 is a sectional view of the metal cap for the opposite end of the 1921. Selial No. 483,446.-

inspection board from that with the ratchet wheel. Fig. 8 is an end elevation of a triangular form. of inspection board or bar to provide three different colored surfaces for inspection; and F ig. 9 is an end elevation of a rectangular form of inspection board or bar to provide four inspection surfaces.

Like characters of reference refer to cor responding parts in the several views.

The numeral 10 designates the supporting if anie of the machine whichhas the front standards 11 with the rearrwardly projecting lower frame portion 12 upon which the inspec-tionframe mechanism is supported.

The lower frame portion 1'2 has the yarn reed or comb 13 on its rear end through which the threads or strands of yarn 14 are inser d in threadingthe machine, thence iassing beneath the roll 15 and upward over the roll .16, whichroll 16 is supported upon

standards

17 and 18 sufliciently higher than the front standards 11 to give a slight downward incline to the yarn as it' passes down over the rotatable inspection boards'or bars 19 which are .rotatably supported upon the

side rails

20 and 21. The side rails 20 and 21- .extend from the supports Hand 18 to the front standards 11'. The threads then pass through a second yarn reed or 001111922 andover a roll 23, thence downward-to the yarn beam or roll-2d.

It is apparent that the operator or yarn inspector standing in front ofthe machine at the standards 11 can quickly glance over the strands of yarnas theyswiftly pass over the inspection boards 19, noting any sluhs or knots or other imperfections as shown at 25 in said yarn, which imperfections can be quickly corrected,thereby giving yarn of substantially the same size or diameter throughout. its length so that it will weave smoothly into a piece of cloth.

The inspection boards or bars 19 are preferably arranged with different colors on the difi erent sides thereof, as for example, black on one side as shown on three inspection boards at 26 in Fig. 2, and white as shown at 27 on three others, the dark color giving more perfect inspection of light colored yarns, and the light color giving more perfect inspection of dark colored yarns as will be readily understood. The inspection boards or bars may be triangular or quadrangular in cross section when additional colored surfaces are desired.

The angle of inclination for the inspection boards 19 is according to the light in the different portions of the day or the placing of the machine in relation to the light openings or windows. I

An inspection board 28 is provided on the

standards

17 and 18 so that in threading up the machine, the yarn ends may be inspected as they are raised over the roll 16, such inspection continuing until the yarn ends have been started onto the yarn beam 24, after which the larger and far better field of inspection on the rotatably adjustable inspection boards or bars 19 are used for such inspection.

The inspection mechanism as hereinbefore describedis preferably built upon a multiple drum spooling machine so that the operator can inspect the yarn and operate the multiple drum spooler at the same time, and the arrangement of the inspection boards 19 in their spaced relation aids greatly in this combined arrangement of the two mechanisms. The inspection boards 19 are mounted on the

rails

20 and 21 in spaced relation sufliciently apart to permit the light to pass down through the yarn and inspection boards to the rolls and spools beneath the same so that the eye of the inspector instantly detects an end reeling upon, the wrong spool, or any other error in spooling the yarn and at the same time continues his inspection of the yarn.

In running yarns having different colors twisted into the same, it is apparent that a portion of the inspection boards 19 may be turned for one color, and another portion for asecond color, and a plurality of colors may thus be cared for, each color being best inspected over its particular inspection boards. Where more than two different colored surfaces are required, the inspection boards or bars may be made as hereinbefore stated, in the triangular or quadrangular or even a larger number of surfaces so that a plurality of colors are always at the command of the operator of the machine,

What is claimed as new is:

1. The combination in a frame having a plurality of spools over which yarn is run. of a plurality of spaced inspection boards mounted thereon over which said yarn is also run, the parts being so located that said spools can be seen through the spaces between said boards.

2. The combination in a frame having a plurality of spools over which yarn is run, of a plurality of spaced adjustable inspection boards mountedthereon over ,which said yarn is also run, the parts being so located that said spools can be seen through the spaces between said boards.

3. The combination in a frame having a plurality of spools over which yarn is run,

of a plurality of spaced rotatably adjustable,

inspection. boards mounted thereon over which said yarn is also run, the parts being so located that said spools can be seen through the spaces between said boards.

1. In a yarn inspecting machine,a plurality of rotatably adjustable inspection boards each having a plurality of different colored. surfaces thereon, and means for running strands of yarn over said inspection boards.

5. In a yarn inspection machine, a plurality of rotatably adjustable inspection boards, said inspection boards each having different colors on the different sides thereof, and means for running the strands of yarn over said inspection boards 'on said machine.

6. In a yarn inspection machine, a plurality of rotatably adjustable inspection boards having different colors on the different sidesthereof, metal caps with axial pins for rotatably mounting the ends of said boards, a ratchet at one end of each of said boards to hold the same in the adjusted position, and means for running the strands of yarn over said boards.

In testimony whereof I have afiixed my signature in the presence of two witnesses.
