Langston, 1701 W. Berry, Fort Worth, Tex. Filed Feb. 5, 1962, Ser. No. 171,111 Claims. (Cl. 68-27) This invention relates to thread dyeing devices and is a continuation-in-part of my copending application Serial No. 108,637, filed May 8, 196 1.

The primary object of the preset invention is to provide a simplified construction for selectively dyeing thread different colors.

Another object is to provide a multiple color thread dyeing device which has fewer working parts and one which will not require cleaning as often as other devices for the same general purpose.

Another object is the provision of a thread tensioner in a multiple color thread device, which tensioner is so located and arranged that uniform feeding of the thread through the device is assured.

A particular object of the invention is to provide a device of the described class including splined coaction between a dye marker and its supporting member for convenient yet positive action.

These and other objects will become apparent from the following description and accompanying drawing, wherein:

FIGURE 1 is a front elevational View of a multiple color thread dyeing device in accordance with the present invention.

FIGURE 2 is a vertical sectional view taken on line 2-2 of FIGURE 1.

FIGURE 3 is a broken perspective view of one end of the base plate.

FIGURE 4 is an inverted broken perspective view of the marker supporting body.

FIGURE 5 is a broken front elevational View and partly sectional view of a modified form of the invention.

FIGURE 6 is a vertical sectional view taken on line 6-6 of FIGURE 5, and

FIGURE 7 is a perspective view of one of the markers in accordance with the modified form of the invention.

The form of the invention shown in FIGURES 1 through 4 includes an elongate rectangular base plate 10 having a similarly shaped body 11 mounted thereon. The base plate 10 is designed to be mounted on the head of a shoe repairing sewing machine, not shown, and the body 11 is located to the left of the operator. Also mounted on the base plate 10, and to the right of the operator, there is a vertical spool pin 12 rotatably supporting a spool of thread, and between the spool 13 and the body 11 there is a thread tensioner, generally designated by the numeral 14. The tensioner 14 is comprised of a threaded stud 15 projecting upwardly from the base plate 10, a thumb nut 16 on the upper end thereof, a coiled compression spring 17 around the stud and beneath the thumb nut and a flanged tension disc 18 rotatably mounted on the stud and in turning contact with the upper surface of the base plate.

The upper surface of the body 11 is provided with logitudinally aligned bores 19' for slid-ably receiving cylindrical barrels 20, which, in turn, receive commercially available dye markers 21, such as those manufactured by Carters Ink Co. The dye markers 21 have tubular bodies or reservoirs, not numbered, which are functionally received in the barrels 211. Inwardly directed fianges 22 in the lower ends of the barrels 20 locate the markers 21 for fully inserting the same in place. Smaller bores 23 in the body 11, and coaxial with the first described bores 19, receive the marker ferrules 24 and permit the felt tips 25 thereof to extend beneath the body 11 when the barrels 20 are in their lowermost positions. Each barrel 20 has a forwardly extending projection 26 for manually raising and lowering the dye markers 21. Vertically disposed bayonet slots 27 are formed in the forward face of the body 11 to accommodate the projections 26.

A longitudinal channel 28 is formed in the upper sur face of the base plate 20 and has felt pads 29 therein located beneath and to be contacted by the felt tips 25 of the dye markers 21. While the word felt is used herein, it is to be understood that other absorbent resilient material may be used in place thereof, after the pads 29 are in place, the body 11 is secured to the base plate 10 by screws 30 as shown in FIGURE 2.

Thread 31 from the spool 13 is looped about the tension disc 18 and enters the body 11 through an end opening 32 which communicates with a longitudinal groove 33 in the bottom of the body and which groove connect-s wiflr opposite sides of the small diameter bores 23. The thread 31 extends through the groove 33 and outwardly through another end opening 34. The thread 31 is then threaded in the sewing machine in the usual manner.

The modified form of the invention includes the described base plate 10, channel 28 and pads 29 therein, to gether with the described spool pin 12 and tensioner 14. However, the body 11a is modified to receive special dye markers 35, each consisting of a cylindrical reservoir 36 having a relatively thick wall, a screw cap 37 on the upper end, a depending tubular ferrule 38 integral with the lower end thereof and a felt tip or wick 39 extending therethrough. A coiled compression spring 40 is mounted around and secured on the upper end of the ferrule 38 and makes spring contact with the upper surface of the base plate 10 when the marker 35 is in its lowered position. As in the first described form of the invention the body 11a includes the longitudinal groove 33 in the bottom surface thereof and

openings

32 and 34 in the ends of the body for receiving the thread 31.

Aligned vertical bores 41 extend through body 11a and slidably receive the lower portions of the markers 35. T-slots 42 are formed in the surfaces of the cylindrical reservoirs and are engaged by the inner ends of screws 43 mounted in the forward wall of the body 11a.

Both forms of the invention operate in substantially the same way. Both have splined coaction between the

cylindrical marker reservoirs

21 and 36 and their respective supporting bodies 11 and 11a. In the first form of the invention the projection 26 associated with the markor 21 containing the selected color is first moved laterally and then downwardly to cause the felt 25 thereof to contact the thread 31 moving therebeneath. The weight of the barrel 20 and the marker 21 hold the felt 25 in place. In the second form of the invention the projecting upper end of the reservoir 35 is pressed downwardly and then rotated to hold the felt 39 against the thread 31. Suitable ca-ps, not shown, may be placed over the felts 25 and 39 when the device is not used for long periods of time.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways within the scope of the appended claims.

What is claimed is:

1. In a multiple color thread dyeing device comprising a body for mounting on the head of a shoe sewing machine, said body including at least two vertical bores in side by side relation, dye marker assemblies slidably received within said bores, each said dye assembly including a cylindrical body and a depending marker felt, a base plate beneath said body, means guiding a thread beneath said felts and guide means coacting said markers with said bores, said guide means of sufficient longitudinal movement to permit said felts to contact said thread.

2. In a multiple color thread dyeing device as defined in claim 1, the construction including a thread tensioner mounted adjacent said body and coacting with said thread.

3. In a multiple color thread dyeing device as defined in claim 1, the construction including felt pads supported by said base plate, said pads being located beneath said marker felts.

4. In a multiple color thread dyeing device as defined in 5 claim 1, the construction wherein said means guiding a thread includes a longitudinal thread receiving groove in the bottom of said body.

5. In a multiple color thread dyeing device as defined in claim 1, the construction wherein said base extends 10 References Cited in the file of this patent UNITED STATES PATENTS McGrew July 5, 1955 Troy Mar. 11, 1958 OTHER REFERENCES Germany, printed application N5138, June 14, 1956.
