51. REGIS PAPER COMPANY, OF NEW YORK, N. Y. A CORPORATION OF NEW YORK SEWING Application filed' April 20, 1925. Serial No. 24,364.

This invention relates to sewing, and more particularly to lubricating the thread and preventing the overheating of the sewing machine needle.

A sewing machine cannot be run at any considerable speed in sewing certain kinds of material, such as paper, without overheating the needle, unless some provision is made to prevent this result. According to this invention' the thread is lubricated, a' blast of' air is directed against the needle, and vaporizable liquid is supplied in close proximity to the needle. Other features of the invention will appear as the description proceeds.

In the accompanying drawing forming part of this specification, Fig. lis a somewhat diagrammatic elevation of a sewing machine adapted to carry out this invention; Fig. 2 is a somewhat diagrammatic section substantially on the line 22 of Fig-1, showing the relation of the air nozzle to the needles.

The particular construction of the sewing -machine is immaterial. One form of sewing head 10 is shown having an arm 11 supporting the needle operating parts. A pipe12 is attached to this arm in any convenient manner, as by clips 13, and is bent downward toward the needle and terminates in a nozzle 14:. Preferably this nozzle is of an adjustable type so that, by turning thetip 15 of the nozzle, the size of the opening may be varied. A stop-cock 16 is provided for shutting olf the air completely, when desired, without as changing the adjustment of the nozzle.

In the construction shown, a bracket 17 is attached to arm 11 and is adapted to support a receptacle 18. The receptacle 18 is pro- Vided with a roller 19. A thread 20 is led from any suitable source through an eye 21 on the receptacle, beneath the roller 19 and out through another eye 22 to suitable tension means 23 on the sewing machine, from which it passes to the needle in the usual manner.

Thereceptacle is filled, or partly filled, with a lubricant24. The preferred form of lubricant is soft soap, or a mixture of soap and water. f The sewing machine maybe provided with one or more needles. In the form shown the thread lubricated. In order that the' there are two needles 25 and 26, as shown in Fig. 2. Thread 20 is led to needle '25, and another thread 27 may be led through receptacle 18 on one side of thread 20 and forward through any desired tension means to needle 26.

In the arrangement shown in Fig. 2, it is clearly indicated that nozzle 14 is adapted to play a jetof air 28, indicated in that figure, primarily against needle 25, but a little out of direct alignment with that needle, so that a portion of the blast passes on unimpeded to needle 26. In this way both needles are cooled by a blast through one nozzle. A small nozzle is used, and a narrow blast is directed exactly onto the needle or needles, so that a minimum power for producing the blast is necessary. IVhile-the blast may be directed against the needle alone and produce suificient cooling, it is preferable to have it contact the thread, and to have the thread moistened by some liquid, such as water, Which-is vaporized by the action of the air and produces an additional cooling effect in the immediate vicinity of the needle.

In order to avoid friction of the needle on the thread as well as friction of the thread through the material and against other parts of the sewing machine, it is desirable to have an proper amount of lubricant may be used and that it may remain in the desired condition, it is preferable to use a lubricant that is not vaporized by the action of air at ordinary tempcraturesa A lubricant such as soap is preferable to such a lubricantv as oil, in sewing paper, because soap is not absorbed by, and does not materially affect the condition of, the paper around the needle holes, as does oil. Vaporizable liquids other than water might be used for their cooling effect, and lubricants other than soap might be mixed I with the cooling fluid, but soap and water form a desirable combination which is not costly and is readily obtainable, and the two substances are completely miscible and easily applied.

It is evident that the presence of a vaporizable liquid inthe-thread will have a cooling effect on the'ncedle even in'the absence to v of a specially directed jet of air, as there will be always some vaporization of the l1qu1d adjacent the needle and consequently some cooling effect, which will increase automatically as the temperature of the needle increases. A vaporizableliquid might be supplied in the vicinity of the needle by means other than the thread, either with or without the jet of air. Therefore, while moistening the thread with a vaporizable liquid, lubrieating the thread, and directing a jet of air against the needle and adjacent thread are features which may be combined advantageously and work together to produce a result which is more than the sum of their separate results, it is possible to obtain beneficial results from less than the complete combination disclosed. h

Numerous other changes in the exact combination disclosed might be made within the scope of the invention claimed and still retainsome of the benefits of this invention. The scope of the invention is indicated by the following claims.

What I claim is:

1. The method which consists in moistening a thread with a vaporizable liquid, passing the moistened thread through the eye of a needle, sewing paper with the needle and thread at such a rate of speed as to heat the needle, and directing a jet of air against the needle and the moistened thread beside the needle. 2

2. The method which consists in moistening a thread with a vaporizable liquid and a lubricant miscible with the liquid, passing the thread through the eye of a needle, sewmg paper with the needle and thread at such a speedas to heat the needle, and directing a jet of air against the needle and against the thread beside the needle.

3: The method which consists in moistening thread with soap and water, passing the thread through the eye of aneedle, seving paper with the needle and thread at such a speed as to heat the needle, and directing a jet of air against the needle and against the thread beside the needle. Y

4. In a sewing machine, to operate the needle, in position to direct a regulated blast of air against the needle to prevent its overheating, a pipe leading to said nozzle and a stop-cock in said pipe.

a needle, means anadjustable nozzle the thread adjacent to the 5. In a sewing machine, a needle, means to operate the needle, means to guide thread through the receptacle on its way to the needle, and means to direct a jet of air against the needle.

6; In a sewing machine, a needle, means to operate the needle, areceptacle, means to guide thread through the receptacle to the needle, and means to directa jet of air against a receptacle for liquid, I
