THREAD-WAXING DEVICE.

Specification of Letters Patent.

Application filed August 19, 1912. Serial No. 715,799.

To all tohom it may concern:

Be 1t known that 1, ANDREW EPPLER, a

citizen of the United States, residing at scription of the invention, such as will en-' able others skilled in the art to which it appertains to make and use the same.

The present invention relates to Wax thread shoe sewing machines, and more particularly to thread waxing devices for such machines.

The invention is designed primarily as an improvement in thread waxing devices of the type which comprise a receptacle .for the wax, a heating device extending into the receptacle and surrounded b the wax contained therein, and devices or guiding the thread,into and out of the receptacle.

In thread waxing devices of this character it frequently happens that the heat transmitted by the heating device is not sufficient to melt the wax thoroughly at the point where the thread passes through the receptacle, and that the wax therefore does not permeate the thread, but the thread receives merely a surface coating of wax inthe waxing device. Also the heat of the heating de vice is often not suflicient to melt the wax throughout the receptacle, so that a layer of hardened wax forms about the inner walls of the receptacle, and the wax used up by the thread is not replenished in a sat1sfactory manner by the supply of wax in the receptacle.

The primary object of the invention is to produce a thread waxing device of the character referred to, with an improved heating device which will insure thereduction of the wax to the r0 er consistency to permeate the thread where the thread passes through the receptacle, and the meltin of the wax throughout the receptacle. 1th this object in view the invention contemplates the provision in 'a thread waxing device havin ,a wax receptacle of a heating device exten ing into the receptacle anrhinto the wax contained therein, and provided with anenlargement extendm over and 10- rated adjacent to the base of t e receptacle. By this provision the heat transmlttin surface of the heating device is increase and the wax atthe base of the receptacle and.

above the enlargement is melted and flows in toward the heating device by which it is Patented Mar. 24., 1914.

ned in a thoroughly melted condi tion. Considerable heat is transmitted to the base ofthe receptacle and thereby con- 3 ducted to the side walls of the receptacle and prevents the formation of .a layer 0 hardened Wax about the inner wall of the receptacle. The enlargement in the heating device is preferably constructed so that it'-'=- extends over substantially the entire area of.

the base ofthe receptacle.

In the accompanying drawings illust-rating the invention in the best form at present known to the inventor, Figure l is a plan view of the thread waxin device; Fig. 2 is a front elevation of the t read waxing device with a portion of the receptacle broken away to show the interior of the receptacle;

Fig. & is a section taken on the line 3-3 of Fig. 2; Fig. 4 is a side-elevation of the device; Fig. 5 is an enlarged detail plan of aportion of the waxing device as illustrated in Fig. 1; Fig. 6 is a section taken on the line 6-6 of Fig. ,5; and Fig. -7 taken on the line 77 of Fig. 5.

u 1s a section I The thread waxing device comprises a bracket 1 secured in any suitable manner to the frame of the sewing machine to'which the waxing device is applied; said bracket being constructed to form a cover for the wax receptacle, as indicated at 2. The max receptacle 3 is adjustably secured to the bracket 1 so that it may be raised and lowered with relation to the bracket. To this end a downwardly extending rod 4 is secured to the bracket 1, and the receptacle 3 is provided with a split clamp 5 for clamping the receptacle in position on the rod. The clamp is provided with an actuating bolt 6 having an enlarged head which may be mani ulated by the operator to clamp the receptace on the rod and to unclamp the receptacle when it is desired to lower it on the rod. A collar or washer 7 is attached to the lower end of the rod 4, and-serves as.v

a stop to prevent the receptacle from slipping ofltthe rod when ,it is lowered.

In order to heat the wax in the receptacle a heating device is arranged so that it extends down into the receptacle and into the wax contained in the receptacle. This heating device is provided with an enlargement extending over and located adjacent the base.

a 30 ing device, and by arranging t of the receptacle, and devices for guiding the thread are preferably mounted so that the thread is guided through the receptacle in proximity to the heating device.

In the illustrated embodiment of the invention the heating device is constructed to contain a heating fluid, preferably steam or hot water.

In the construction illustrated the heating device comprises pipes 8 and 9 connected by a plate 10 attached to the lower ends of the pipes and provided with a chamber or passage connecting-the pipes. The pipes 8 and 9 are clamped to the bracket 1 in a position. such that the plate 10 is located near the base of the receptacle. The plate 10 forms an enlargement of the heating device, and is preferably constructed so that it overlies substantially the entire base of the reeeptacle.

In order to clamp the pipes 8 and 9 to the bracket 1, the bracket is provided with recessesl to receive the pipes, as illustrated in Fig. 1', and the pipes are clamped against the bracket by means of a clamping plate 12 actuated by a clamping bolt 13. By this construction the heating device may be clamped in any desired position with relation to the receptacle and the plate 10 may be located at different distances from the base ofthe receptacle as desired.

The pipes 8 and 9 are connected with entrance and

return pipes

14 and 15 for the heating fluid by means of nipples 16 threaded into the tubes 8 and 9 and interiorly threaded to receive the pipes 1a and 15. An angular plate 17 is secured to the side of the receptacle thereby forming a chamber for the reception of lumps of wax which are 40 placed therein. to supply the receptacle, said plate being formed with a series of slots 18 through which the wax may flow when melted into the body of the receptacle. A

th'read truck 19 for guiding the thread through the receptacle is carried by a sup porting frame 20 which is clamped to the pipes 8 and 9. r

The pipes 8 and 9, and the connecting plate 10, form a substa'ntially U-sha "d heatthread truck 19 as described,ll:he threadis guided through th receptacle in proximity to the heating device. The plate 10 furnishes a large heating surface, and the heat from said .5 plate rises through and ra ses the temperature'of the wax througl'ro t ejzlostantially the entire receptacle. Heat i tr: emitted by the plate 10 tothe base of th receptacle, and thcruhv conducted to the walls thereof,"preventh inner .walls' of the receptacle. The wax above the plate and along the walls of the receptacle is mcltedandfiows in toward the center of the receptacle where the heating i1 device extends into therecepta'cle and where in construction as the stripping device illusin the receptacle and comprising a heat con- ,j-the hardening ofthe \vax along the.

the thread passes therethrough. The wax at the center of the receptacle and in proximity to the thread is readily reduced,to, and maintained att-he proper consistency by the heat transmitted by the heating device, and particularly by the pipes 8 and 9 thereof. By the provision for adjustment of the plate 10 with relation to the base of the receptacle, the heat transmitted to the base of the receptacle by said plate may be varied as desired.

The stripping device for stripping the wax from the thread as the thread emerges from the receptacle is substantially-the same trated in the patent to Ashworth, No. 1,015,- 7 72, dated January 30, 1912. This stripping device comprises a compressible block 21 which is perforated to provide a passage for the thread, and which strips the wax from the thread as it passes therethrough. The block is compressed by a compressor 22 which is seated in a cap 23 threaded upon the upper end of a socket 24 mounted on the cover of the wax receptacle. To permit the ready removal of the block, a split sleeve 25 is provided" to receive the block, and the sleeve is fitted into the socket 24. The socket is provided with a dovetailed rib 26. which is received in a dovetailed recess in the cover of the wax pot, and the socket is held in the recess by means of a retaining screw 27.
