METHOD OF WAXING- THREAD.
Specification of Letters Patent.
Patented Oct. 2'7, 191d.
1909, Serial No. 525,297. Divided and this application filed May 9,
1910. Serial No. 560,174.
To all whom it may concern:
Be it known that I, CLARENCE L. EATON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Methods of Waxing Thread, of which the following description, in connection'with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
The invention to be hereinafter described relates to a method or process of waxing thread, and is a divisional of my prior application, Serial No. 525,297, filed October 29, 1909, now Patent No. 965,379, dated January 26, 1910, wherein an approprlate' means is shown, described and claimed for carryingthe present invention into effect.
The thread used for shoe sewing is ordinarily drawn from a source of supply and passed through a waxing device by which it is provided with a waxing composition. This Waxing composition is formed of various ingredients, such, for instance, as paraflin and rosin, and in order that they be properly applied to the thread, such composition is ordinarily maintained in the liquid state by the application of heat. On the one hand it is desirable that the waxing composition be kept heated to a high tem pcrature and in the liquid state, while on the other hand it should not be permitted to become overheated; because, when so overheated, the ingredients composing the waxing composition become so far" separated that the composition is spoiled so far as its use for thread waxing is concerned,.as is well understood by those skilled in the art; and, moreover, the composition boils and runs over the top of its container when so overheated.
Theaims and purposes of the present in-'v vcntion are to provide a process or method of'waxing thread, whereby the waxing composition may be maintainedat a desirable high temperature and in the liquid state, and yet be effectually prevented from becoming injuriously overheated, all ofwhich in connection with the accompanylng drawings which show a means for carrying out the process or method.
In thedrawingsz-Figure 1 is a side view of any usual or desired form of waxing composition may tank which may be secured to the wax thread sewing machine and used in connection therewith, if desired; and Fig. 2 is an end view thereof with parts broken away to show the elements beyond, said figures illustrating one form of means for carrying the present method or process into practical effect The waxing tank 1 may be of any usual or desired character, and preferably may be formed of cast metal provided with a suitable supporting bracket 2 by which it may be secured to the frame of a wax thread sewing machine, or elsewhere, as indicated 1n Flg. 1, I
Disposed at the bottom portion of the waxing tank'l there is a heating chamber 3 connected at one part by means of a pipe 4 with a source of steam or hotair supply, and at another portion provided with a discharge pipe 5, as indicated in Fig. 1. In these .respects, as well also as with respect to the inlets 6 and 7 for the thread 8 to be waxed, the waxing tank may be of any usual or desired chara'ctenand the waxing be maintained in a heated condition by any suitable or desired means, it being understood that with respect to these features the invention is generally applicable.
As well understood by those skilled in the art, the waxing composition when supplied to the trade is in solid form and among its constituent elements there is paraflin and rosin. For the proper application of this composition to the thread, it is first heated in order to reduce it to a liquid state and maintain it at a sufficiently high temperature to make such composition thoroughly liquid,
less than the full.
ing pulley 18.
sewing operation or after the treated thread has become cold. Moreover, under the conditions above noted, the waxing composition is liable to boil over the waxmg tank and run upon the floor, thus engendering great waste of material. These objectionable characteristics are overcome by the present in-.
As one form of means for practising the.
method or process, the drawings show a waxing tank 1 provided with suitable bearings 9 and 10 in which is supported a shaft 11 having secured thereto a series of buckets 12 which dip into the waxing composition in the tank 1 and, by rotation of said shaft,
stir the composition in the tank and lift portions thereof from the tank and then, as the shaft revolves, said buckets permit the portions of the waxing composition raised.
by them and cooled somewhat to run back into the waxing tank.
As one means .of operating the shaft 11, said shaft is projected through one side of the tank, as indicated in Fig. 1, and provided with a worm wheel 13 which is engaged by a worm 14 on a suitable shaft 15, said shaft 15 being preferably provided with a clutch member 16 adapted to engage a complemental clutch member 17 connected to a pulley 18, or other means, which may be driven from a suitable source of power. The clutch members may be caused to engage by suitable hand operating devices,'as' the wheel 19 secured to the hub of the driv- Obviously changes may be made in the general form and character, both of the tank, heating means forthe waxmg-composition, and the driving or operating devices for thecooling buckets; and it will be clearly apparent that the cooling buckets may be operated in any manner desired, the
characteristics of the invention in this respect being that they be constructed so that when in operation they will dip down into and then permit the waxing composition and lift portions thereof from the tank, thereby enabling suchportions to become cooled to some extent, such portions to run back into the waxing tank. By this characteristic operation it will be noted that not only is the waxing composition kept thoroughly mixed, but it is' prevented from attaining a temperature calculated to injure the waxing composition for cause it to overflow from the tank.
What is claimed is:
1. The process or method of waxing sewing thread which consists in subjecting the waxing composition to heat-to maintain the same in liquid state, removing portions of the liquid composition from the mass from. time to time during the application of heat thereto and returning such portions after they have been sufficiently cooled to prevent separation of the ingredients of the compo- 'sition in the body of the liquid by overheating, and simultaneously commingling and stirring the main body of the mixture and passing a thread through the said main body of the composition at a point where the de sired temperature and mixtureof the composition is maintained.
2. The process or method of waxing sewing thread as it is delivered to the sewing devices which consists in subjecting the waxing composition to the continued action of heat to maintain the said composition in easily flowing liquid form, cooling portions of said liquid waxing composition at intervals during the application of heat to the body of the said composition and causing the lower body portions of the composition to prevent overheating of such lower body portions and consequent separation of the ingredients at such point, and simultaneously drawing a thread through the said lower body portion of the composition where the desired temperature and character of composition is malntalned.
In testimony whereof, have signed my 100 name to this specification, 1n the presence of? two subscribing witnesses.

the said cooled portions to intermingle with Gerreetion in Letters Patent N0. IO HOa [t is hereby certified that Letters Patent No. 1,11 5,et18, granted October 27. 191% upon the application of Clarence L. Eaton, of Boston, Massachusetts, for an improvement in Methods of Waxing Thread, were erroneously issued to Thomas Gustave Plant, as assignee of the entire interest in said invention, Whereas said Letters Patent should have been issued to United Shoe Machinery Company, of Paterson, New.- Jersey, a corporation of New Jersey, as 'assignee by mesne assignments of the entire interest in said invention, as shown by the records of assignments in this office; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent- Oflice.
