FRED ASHWORTH, 0F BEVERLY, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, T0 UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY,\A COR- THREAD-WAXING- DEVICE.

To all whom t may concern: l

Be it known that I,l FRED Asnwon'rH, a citizen of the Unitedl States, residing at Beverly,.in the county of Essex and State of Massachusetts,have`invented certain new and useful Improvements in Thread-Waxing Devices; and 'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart'to` which it appertains to make and use the same.

This invention relates to thread waxing' devices, and more particularly to wax pots for waxing `a'plu'rality'of threads for use in a shoesewing machine.

In' sewing machines for sewing utsoles to the bottoms of shoes it is often desirable to use a different kind of thread for the shuttle than is used for the needle. These threads may be of different colors and may be waxed with waxes of different colors or waxes 0f different chemical and physical properties.

The primary object of the present invention is to provide 'a thread waxing device for an outsole sewing machine by which the shuttle and needle threads may be waxed separately with different kinds of waxes and by which different kinds of waxes having different specic heats may be held in proper condition to impreofnate the thread.

In accordance with this object a feature of the invention contemplates the provision in a thread waxing device of a heating member and a plurality of separate wax receptacles independently mounted for movement relatively to said heatin member.

Other features of the lnvention consist in certain features of construction and combinations of parts, the advantages of which will be apparent to those skilled in the art from the follow-ing description.

The various features of the invention are illustrated in the accompanying drawings in which Figure 1 is a top plan View of a wax ot embodying the invention in its preferre form; Fig. 2 is a view in side elevation of the waX pot; and Fig. 3 is a view in rear elevation of the wax pot.

Specification ofLetters Patent.

and 12 consist of hollow receptacles which have the usual receiving compartment 18 for the umnelted wax and a. thread waxing compartment 20 for the melted wax, which is separated from the compartment 18 by v a perforated partition 22. Apertured lugs 24, formed on the front and rear faces of the wax pots, are slidably mounted on rods 26 which are secured in opposite ends of the su port 14.

' fromth'e member 16 and may be shifted on the rods 26 to bring their rear faces directly into contact with the heating member.

The different kinds of waxes for waxino' the shuttle and needle threads may have dif ferent specific heats and require diii'erent amounts of heat to hold them in the proper molten condition to properly impregnate the thread. The temperature of the heating member cannot be varied to any great extent when heating with pressure or exhaust steam, and in order to vary the amount of heat imparted to the wax, the wax pots are arranged to be adjusted toward and from the heating member. To adjust the wax pots, adjusting bolts 32 are rotatably mounted in the outer walls of the wax pots and the inner ends of the bolts are threaded into lugs 34 formed on the lower face of the bracket 14. The adjustment of the wax pots with relation to the heating member permits an accurate control of the amount of heat imparted to the wax and permits practically any kind of wax to be held in a molten state. When it is desired to first melt the wax, the pot may be placed in direct contact with the heating member and after the wax is melted, the pot may be withdrawn from the heating member a sufcient distance to hold the wax in a molten condition and still avoid boiling. Further, if it is not desired to continuously use the shuttle wax, the pot containing the shuttle wax may be withdrawn from the heating member a sufficient distance to hold the wax in a semi-molten condition until it is desired to use it.
