AUGUST R. SCHOENKY, OF SOMERVILLE, MASSACHUSETTS, ASSIGNOR T0 THE REECE BUTTON HOLE MACHINE COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

To all whom 'it Imay concern:

Be it known that I, Accifs'r Ii. Scnonxitv, a citizen of Ithe United States, residing at Somerville, county of Middlesex, State of 1 Massachusetts, have invented an Iniprovenient in T hread-ll'axing Devices, of which the following description. in connection with the accompanying drawing, is a specification. like characters on the drawing repof the wax mass through which the thread passes at a sutlicient temperature to keep it iii a propel' state of iuidity without danger that the entire wax mass will become heated Vto such an extent as to boil over. and also to provide means whereby any excess heat that may 4be delivered to the wax mass through which the thread is drawn will be dissipated without eti'ecting any overheating of the wax mass.

Another object of the invention is to provide a novel wax-containing receptacle which is removably sustained in a receiver or holder so that the receptacle can be readily removed from the holder whenever it is necessary to do so for cleaning it or repairing it.

Another object ofthe invention is to provide a thread-waxing device in which the thread extends transversely through the wax-containing receptacle and the hitter is provided with means to prevent the escape of wax through the thread inlet passage and with novel means foi-,stripping thev wax from the thread as it isgdrawn through the delivery passage.

Other objects of my invention are to improve thread-waxing devices` all as will be more fully hereinafter set forth.I

In order to give an iini'lerstanding of my invention .I have illustrated in the drawings a selected embodiment thereof which will now be described. after which the novel features will be pointed out in the-appended claims. n

In the drawings Figure 1 is an end view of a thread-waxing device embodying my invention; Fig. :2 is a side view of Fig. 1

with parts broken out to better illustrate the construction; Fig. 3 is a section on the -line 3 3, Fig. 2.

The wax which is usually used for waxingv thread iii a wax thread sewing machine becomes solid or semi-solid at normal teinperatures, and it is customary to heat the wax in order to render it sufficiently fluid to permit the thread to be drawn therethrough. It is necessary, howeveizto exercise considerable care in applying the heat to the wax because if the wax becomes too hot it deteriorates in quality and is likely to boil over. thus entailing extra work. In order to avoidthese undesirable conditions I have provided herein a novel wax-containing receptacle and a novel manner of heating the i'eceptacle by which the heat is applied to that portion only lof thereceptacle through which the thread passes whereby the portion of the wax mass through which the thread is drawn is kept at the proper temperature without danger that the entire body of the wax will become unduly heated. In fact with my invention it is not necessary to heat the entire wax mass, but only the particular portion of the wax through which the thread is drawn.

In the embodiment of the invention herein illustrated the wax is contained in a waxholding receptacle 1 which is removably sustained in a holder or casing Q, the latter being constructed to present side walls. the latter having a box-like structure in which the receptacle l is received and being open at the top to permit the receptacle to be i'emoved or placed in position. This top is closed by a cover 3 shown as hinged to the casing at l. said cover constituting the cover for the receptacle l. `The wax-holding receptacle 1'is shown as having an outwardlyprojecting flange 5 at itsupper edge which -overlies the top edgey of the casing 2 and which assists to support the receptacle in the casing. Then the cover 3 is closed it rests againstthe flange v5, as shown, and thus assists in holding the receptacle 1 in place. This wax-holding receptacle 1 is provided near its lower end with a thread inlet passage 6 and a thread outlet passage 7, said passages preferably being situated in alinement with each other so that the thread to be waxed may be drawn transversely through the receptacle, said thread Patented Apr. 4, 1916. f

`being provided to compress the plug more or less thereby to regulate the pressure thereof against the thread and thus determine the amount of wax to be left on the thread; This wax-stripping device is constructed so that the stripping plug 9 can be readily removed when it has deteriorated to such an extent as to make it necessary to replace it by a new plug. The construction herein provided for this purpose comprises a boss 10 extendingfrom the wall of the receptacle 1, and into which is screw-threaded a sleeve 11 having a central opening in which the stripper 9 is received. Said sleeve 11 has screw-threaded into the end'thereofy a plug-compressing element 12 having a concave inner face 13 that engages the end of the plug, said plug-compressing element 12 being provided with a central aperture 14. through which the thread passes. Adjustment of the element 12 will compress the plug 9 more or less, thus regulating the size of the aperture through which the thread is drawn and consequently the wax-stripping effect of the plug. The sleeve 11 is readily removable frnm the boss 10 and when it has been thus removed the plug 9 can be forced from the sleeve by screwing up the element 12. A simple construction is thus provided for removably retaining the wax-stripping plug in position.

In the illustrated embodiment of my invention the boss 10 is formed as part of an element 15' which is rigidly vsecured to the wall of the receptacle 1.

The means associated with the inlet opening 6 to prevent the escape of waX therefrom is. similar in construction to that employed for stripping the wax from the thread in that Vit comprises a compressible apertured plug-16 confined in a sleeve 17 that is screwthreaded in a boss 18 extending from the wall of the receptacle 1, said sleeve having screw-threaded thereinto a plug-adjusting element 19 having a thread-receiving aper- .ture 20. The outer end of the thread-receiv- -ing aperture is flared, as shown at 21, to

permit the thread to have easy entrance. By adjusting the element 19 the aperture in the compressibl-plug 16 can be so adjusted that it will tit the thread suiiciently tightly to prevent the escape of any wax through the passage 6. This construction has the advantage that the plug 16 can be readily removed sides of the receptacle so that the thread to be waxed is drawn transversely through the receptacle.

One feature of my invention relates to the manner in which the portion of the wax mass through which the`thread is drawn is maintained in its fluid condition withbut necessitating the heating of the entire wax mass. I attain this object by makinglthe lower end of the receptacle 1 in which the

apertures

6 and 7 are formed comparatively narrow in one dimension and providing means for applying heat to said lower portion of the receptacle only. One convenient way of making the receptacle is to make it tapering so that it will have a pointed lower end 23, as shown lin Figs. 1 and 3, the

apertures

6 and 7 being -formed in the pointed end. Means are provided for heating the lower pointed end of the receptacle 1, such means being herein illustrated as a heating element 24 having a groove or recess 25 formed in its upper face in which the lower pointed end of the receptacle 1 Ais received, as best seen in Fig. 3. This heating element 4 may be heated in any=suitable way. l have herein shown it as provided with a steam chamber 26 having a genera-l U-shape in cross section so as tov partially embrace the lower pointed end 23 of the receptacle 1, said steam chamber being provided with an inlet pipe 2:8 and an outlet pipe 27 for the passage of steam to and from the steam space 26, said pipes being shown as extending through the slots 200. This heating element 24 is shown as secured to the bottom of the casing 2 by suitable screws 29, said element resting on leveling' screws 30 by which it is properly leveled. With this construction the heat will be applied to that portion only of the receptacle 1 through4 which the thread passes and as the receptacle is pointed 'at its lower end there will be a comparatively small amount of waX in this heated portion of the receptacle. The heat which is developed from the heating element 24 will be sufficient to maintain the wax in the lower end of the receptacle in a melted condition, thus providing for properly waxing the thread as it is drawnl through the receptacle, but the heat is insuticient to heat the entire wax mass in the receptacle 1 to a point that will tend to d .eteriorateA it or would tend to make it boil over.

It lwill be noted that the wax-containing receptacle 1 rests-loosely onk the heating elec ment 24 and is, therefore, readily separable with which thedevice is used. In the presj ent embodiment of my invention said casing has associate'd therewith an arm or bracket 3l by which the device is bolted or screwed to the machine with which it is used.

lVhile I have herein illustrated the steam chamber 26 as having a 'U-shape in cross section, yet I desire to state that the shape andl size of the steam space or chamber may be varied, depending on the pressure of steam which is used and the temperature which it -1s desired to develop.

An important feature of the present invention is the following novel principle involved therein. The combined means illustrated are such as to give a continuouslycontrolled mode of actionl whereby in effect there are two different portions or masses of wax, namely, a comparatively small mass 4which is subject directly to the high heating influence and through which the advancing thread is drawn;`and, secondly, a comparatively mnch larger massA of wax which not only is not directly subject to the high heating influence but is subject to cooling influence, heat passing out of this part of the wax by conduction, convection and radiation. The `particular construction illustrated is valuable for obtaining this condition lof things by reason of the lower or heated portion of the receptaclebeing tapered or restricted in at least one direction so'as to give a small wax volume through which the thread passes; whereas, the upper or enlarged or diverging portion of the receptacle contains the unheated and comparatively large wax mass referred to, gravity serving to replace in the lower and highly heated portion of the receptacle the wax con- -sumed by use, and the upper receptacle portion being thus available for continued new supplies of wax.

The described principle or mode of action, and the structure or means for securing the same, results in the preservation of a sort 'of balance as between theA two different wax portions and the heat conditions," so that the ture. There may be an extremely sm'all amount of wax so maintained in the desired melted condition. The heating means, of course, must be adequate to make up for any losses of heat in this small waxmass, includ- 'ing the 4heat directly extracted by the waxed thread passingout of the receptacle. Preferably,'the normal heat supply is somewhat more than necessary to maintain the described minimum heat conditions, and thus there is insurance against insufficient heating of the wax portion'through which the thread passes. Excessive supply of heat, or a continued supply of a high rate of heating without a proportionate heat subtraction, is incapable of raising the temperature of the melted wax to an injurious degree. This is owing to the' comparatively large mass of wax, which is not subject directly to the heating influence, but which on the contrary is subject to the cooling influences mentioned. It is believed that the action in thus preserving the desired balance of temperature is somewhat as follows. The heating device 2l completely surrounds and con-v .stantly acts upon the critical wax portion sage of excess heat into the larger mass would take place to an extent dependent upon the excess of heat, so that dangerous overheating of the critical wax mass is avoided.- A certain leeway of temperature variation is permissible. The -larger wax mass is capable of absorbing heat at a comparatively rapid rate without losing its function as a .balance preserver, this being due to its capacity for distributing and constantly throwing off its heat.

Generally speaking,thetotal result of the described action is that variations in heat supply or heat excess serve merely to cause variations in the volume or mass of properly melted wax at the bottoni of the receptacle, and the apparatus is so designed that the extreme portion of the larger mass of wax need Vnot ever become softened to the point of actually melting. j

Another advantage resulting from my invention is that the heatingof the wax is not accompanied by the evaporation of any of the desirable ingredients of the wax. Where the entire quantity of the wax in a wax pot is melted and is kept hot, there will be a continual evaporation of the more volatile ingredients of the wax. This is prevented in Ymy invention because the wax mass which i's maintained at the highest temperature and through which the tread passes is entirely sealed by the wax mass at the upper portion ot' the receptacle and which is ota much lower temperature. In fact, the wax mass at the top ot'tlie receptacle may not be melted at all. or at least it is maintained at so low a temperature that a deleterious evaporation does not take place. As a result all ot' the desirable ingredients ot' the wax :fre retained therein and a superior waxed thread can be produced.

IVhile I have herein illustrated a selected embodiment ot' my invention, I do not wish to be limited to the constructional features shown.
