FRANK F. STANLEY, OF SVVAMPSCOTT, MASSACHUSETTS.

SOLE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,440, dated April 27, 1897.

Application filed May 4, 1896. Serial No. 5 90,137. (No model.)

To all whom t may concern:

Be it known that I, FRANK E. STANLEY, of

Swampscott, county of Essex, State of Massachusetts, have invented an Improvement in Sole-Sewin g Machin es, of which the following description, in connection with the accompanying drawing, is a specication, like letters on the drawing representing like parts. This invention has for its object to improve the construction of sole-sewing machines of the class using a rotating work-supporting horn. These horns are commonly provided with wax-pots, in which the wax has to be kept heated, and the horn has to carry the heating means, and great difficulty is experienced in making and keeping tight the steam connections.

I have devised means whereby the wax-pot is located at the foot of the horn and preferably on the stationary frame of the machine, by which the horn is supported.

The drawing, in section, shows a rotatable horn and part of the framework of a sole-sewing machine.

The framework A is and may be of the shape commonly found in the McKay machines, it having an arched or other shaped bracket A', which receives a bearing c, provided at top with a collar a', on which rests a shoulder a2 of the spindle E of the horn E of usual shape and size.

The horn has its tip provided with any usual whirl e', which cooperates with the usual hooked needle (not shown) to make the stitch.. The tip is rotated by the shafts b c, the gears h c d d d2 cl3, the latter gear being connected to the upper end of a hollow shaft e, extended through the lower end of the horn-spindle and the bearing c, where it is provided with a gear 4o f, which is engaged and rotated in any usual manner commonly practiced in connection with a horn.

The wax-pot D is herein shown as located at or near the lower end of the horn, it being represented as held in place between stands g.

The threadtin the shape of a cop or ball orin other usual mass is shown as led into the wax in the stationary wax-pot I) and out therefrom through a suitable wiper g, and thence into the lower end of the hollow shaft e, and from said hollow shaft about the tension sheave or device 71J and over other suitable guides h h2 to the usual whirl.

I have not shown anyheating means for the wax-pot D, but it may be of any usual or suitable construction and be heated by steampipes or otherwise, the steam-pipes, if used, communicating with a suitable source of steam-supply.

Making the shaft e at the center of rotation of the horn hollow enables the thread to be taken directly from the wax-pot through the said shaft, and it cannot be wound about the shaft as the latter rotates and the thread can be led from any point outside the horn.

The horn-spindle is surrounded by a waterjacket B, in turn surrounded by a cylindrical jacket C, which is heated by steam or hot water and by conduction heats the water in the jacket B, pipes in communication with the latter jacket being carried up within the horn toward its tip to keep the horn and thread warm.

The jackets B and C are and may be all as provided for in United States Patent No. 503,084, dated August 8, 1893, so need not be herein further described.

The spindle E is removed at its upper end somewhat from the shaft e, so as to constitute thereby a heat-chamber to maintain the shaft properly hot.

The sheave h has its periphery arranged within the line of the central opening of the shaft e, so that the thread from the ball in the wax-pot may be led directly therefrom through the central part of the said shaftand over the sheave without necessarily touching in any way the interior of the said shaft, and in this way the shaft is not at all covered by wax.

The spindle is kept suiciently hot to, by conduction, keep the space in the shaft e warm and the wax on the thread in good working temper.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination with the horn, its spindle, and the hollow shaft extended through said spindle, of a thread-conducting tensionsheave above said shaft and having its periphery arranged within the line of opening` IOO of said shaft, and the stationary wax-pot arranged immediately below the open end of and in direct line with the said hollow shaft, substantially as described.

2. A rotatable horn provided with a hollow central shaft for a threadpassage, means to maintain said hollow shaft hot throughout its length, a whirl, a sheave peripherally alined with the axis of said shaft, and located above the same, a stationary wax-pot located i1nmediately below and in line witlrsaid hollow shaft, and a wi per, all combined substantially as described, whereby the thread may be led from the wax in the said wax-pot, wiped and then led centrally through said shaft over said sheave to the whirl,substantially as described.

3. A rotatable horn, a spindle supporting` the same, -a hollow shaft within said spindle and rotating therewith, said shaft bein g separated froln said spindle in its upper portion to constitute a closed heat-chamber, a hotwater jacket surrounding the lower part of the spindle and shaft, a wax-pot below the shaft, a sheave mounted on the horn above the said hollow shaft, said sheaye having its periphery in the axial line of said hollow shaft1 and a whirl, all combined substantially as described, whereby the thread may be passed through the wax in said waxpot and therefrom through the hollow horn-shaft to said sheave and whirl, substantially as described. In testimony whereof I have signed my naine to this specification in the presence of two subscribing; witnesses.
