This feature is niost'ciemly .Withi its openings 4, its projections 6 and catches 7, can be made in one operation; and the cost of manufacture is therefore but little; nevertheless, a very efiicient thread guide element is produced.

I also attach to the rod 3 a guard 11,

i which extends over the edge of the disk toward the center thereof, and rests at its end upon the disk and over the rivet in the end of the rod 3. This guard will keep the thread from ever getting caught between the disk and the arm 3, whenever any slackening of the thread occurs.

In practice, each disk 4 and rod 3 will be located above a bobbin or spool of thread 12, supported by the stem 1; and the particular opening 5 of the disk which is in use will be directly over the axis of the bobbin immediately below it. From the disk the thread passes through a fork 13, and over a hook 14; both the fork and the hook being supported by a casing 15 on the stem 1. The fork is pivotally mounted on a bar 16 aflixed to the casing 15, and en ages a guard 17 at the outer extremity of t is bar. The thread is held between the fork 13 and the guard 17 and the opposite end of the fork has a projection 18 which engages an arm 19 on a shaft or spindle 20, by which the hook 14 is carried. This spindle is actuated by a suitable device (not shown), in the casing 15 to hold the fork against the guard and after leaving the hook 14, the threa passes certain parts of the machine which control stop mechanism, below the hook 14. Should the tension on the hook 14 become too great, the device above mentioned is overcome and the shaft 20 is actuated to release the fork 14. The thread can then drop clear of the fork; and all tension ceases, thus allowing the stop mechanism, not shown, to operate; and the running of the machine is thus interrupted until the operator gives it the necessary amount of attention. The parts above-mentioned and designated by the numerals 13 to 20 inclusive, well known to those skilled in this art, need not be fully set forth.

The disks 4 on the rods 3 are individually adjustable; and neither the rods 3 nor the collar 2 need be moved in order to shift the disks so as to bring the desired openin into line with the axis of the bobbin 12 elow it. Whenever another opening is to be made ready for use the disks can be turned accordingly in an instant simply by manipulating them as above stated. The collar 2 and rods 3 remain fixed and stationary, and the catches 8 engage and disengage the rods 3 automatically, so that both the turning and the locking of the disks can be done at one and the same time.

The openings 5 will intercept knots or bunches on the thread or yarn, and produce such tension as is needed to cause the thread to swing the hook 14 to move the shaft 20 and release the fork 13. If a bunch or knot should strike the fork 13 and be intercepted, a similar result will follow. It has been found that sometimes a bunch or knot in the thread will get past the fork 13 without the thread being stretched enough to release the fork; but with the guide disk 4, such a mishap never occurs. The thread from the bobbin travels straight through the disk, and the openings are just large enough to permit the easy passage of thread of the proper thickness. Hence, any unusual thickness at once chokes up the opening and subjects the thread to tension, thereby stopping the machine and obviating delays that accidents such as the breaking of the thread might entail.

The edge of each opening 5 is punched up to a slight extent, so as to present a smooth curved surface to the thread passing through it.

Having described my invention, what I believe to be new and desire to secure and rotect by Letters Patent of the United tates is:-

1. In a thread guide construction, the combination of a supporting member, a disk rotatably mounted thereon, said disk having circumferential projections to enable it to be manipulated and a plurality of graded openings arranged around its center, said disk also bein provided with cut and bent portions constitutin catches to engage the member and hold t e disk in various positions, and a guard secured to said member and extending across the edge of the disk toward the center thereof.

2. A thread guide construction comprising a perforated rotatable disk, means for mounting said disk, and a guard for the disk secured to said means and projecting over the edge of said disk toward the center of same.

3. A thread guide construction comprising a disk and means for rotatably mounting said disk, the disk having a plurality of yieldable (portions constituting catches to engage sa i means and hold the disk in various posltions.

4. A thread guide construction comprising a disk and means for rotatably mounting the disk, said disk having a plurality of cut and bent portions adjacent its periphery to engage said means and hold the disk in various positions.

5. In a thread guide construction, a rota,- table disk having a pluralit of pairs of ehordaliy-extending cuts adweent its periphery, the portions of the disk between the cuts 0 each pair being bent away from the disk, each pair of portions constituting a catch, and means for sup orting said disk, 1 to be engaged by said unto es.

In testimony whereof, I have signed my name to this specification this 27th day of November, 1916.
