SPECIFICATION forming part of Letters Patent No. 498,505, dated May 30, 1893.

Application filed December 31, 1,?891. Serial No. 416,701. (No model.)

To all whom it may concern:

Be it known that'I, OTIs E. BROWN, a citi-I zen of the United States of America, and a resident of the city of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful ImproveinentsinWax-ThreadSewing-Machines, of which the following is a full, clear, and exact description.

The object of this invention is to provide improved appliances with relation to waxthread sewing machines of which the Goodyear rapid stitcher is a well known type, for the purpose of heating the wax thread, and most especially the terminal portion thereof which is carried to the needle.

To,this end the invention consists, in the combination of a steam jacketed trough, an oscillating take-up arm moving in the arc of a circle in the trough, mechanism connected with and oscillating the take-up arm, a stationary, longitudinally chambered shaft located above the trough and on which the take-up arm oscillates, means for introducing steam into the said shaft, a steam pipe connection between the shaft and the jacketed trough, and a steam conduit leading from the latter.

In the accompanying drawings the present improved appliances are shown together with so much of the sewing machine as necessary to indicate their availability.

Figure 1 is a side View of a part of the post, the take-up mechanism and the shuttle-case of a Goodyear rapid stitcher and of the steam circulating conduits. Fig. 2 is an elevation of the principal parts shown in Fig. 1, taken at right angles thereto. Fig. 3 is a sectional. View hereinafter referred to. I

In the drawings Fig. 1, A represents the post of the well known Goodyear waxthread rapid stitcher.

B is the shuttle-case.

C is the take-up arm having a roll at its extremity, and oscillating forward and backward into and out of the curve sided trough D, on a center stationary shaft 0. and by means of the usual, cam-operated lever and linkconnections, parts thereof being indicated at b. The stationary shaft or is longitudinally chambered.

61 represents a steam pipe of small diameter which is understood as leading from any suitable steam supply, and has a portion thereof indicated at d formed into a loop having the side by side sections thereof curved to conform to the periphery of the shuttlecase B; and the said steam-pipe, of itself, or another section coupled thereto is extended from the said loop portion to a connection at a with one end of the chambered shaft for steam ingress thereinto. The said chambered shaft at its end opposite to that of its steamconnection e has coupled thereto a steam egresspipe, indicated at f which thence extends to the jacket-chamber, g of the said trough. This trough has thejacket chamber inclosing its front and both ends the different chamber portions being all in communication for free circulation of steam therein;

and h represents the steam outlet-pipe extending from the said jacket chamber to waste or otherwise.

The loop formed section C6, of the steam receptacle-conduit which is disposed in an arc form and overlies the shuttle-carriers, is, as shown in Figs. 1 and 2, closedin by the'shield or hood, 2', which has foot-lugs by which it is secured to the rim of the shuttle-case.

From the foregoing description and the illustrations referred to, it will be. apparent, that, with a suitable steam supply furnished for ingress to the pipe-section, d, the steam circulates adjacent the shuttle-case and passes thence to and through the shaft on which the take-up arm for the needle thread is mounted to swing, and thence to, and through, and awayfrom the jacket-chamber of the trough. Consequently, as is manifest, the wax thread carried on the shuttle and its terminal portion passing out from the shuttle-case and the Wax thread of the needle by reason of its engagement with the heated take-up arm and roll and. also of the movement of said take-up arm and roll'in and out of the jacketed trough, will be heated and so maintained heated to thedegree required for the eifective working of the threads in making stitches as well known in wax-thread sewing machines of the type before mentioned.

In Fig. 3, there is shown as applied relative to the shuttle-case, in lieu of a loop section of the steam conduit, an are formed casing, inclosing the chamber (1 to which the steam inlet pipe, (1, therefor is coupled for communication at one end and to which the steam egress pipe d therefor, has the connection at the other end. This latter form of the radiating heater for the shuttle-case performs the same function as the loop but the arrangement shown in Fig. 3 may be performed where a greater steam volume is desired for a correspondingly increased degree of heat adjacent the shuttle-case.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

The combination of a steam jacketed trough
