NEW JERSEY.

T his invention relates to shoe sewing machines and more particularly to a wo-nk supin shoe sewing machines of thewelll'cnown McKay vpe. the work supported during the operations. upon a horn ended withinthe shoe, I'leretofore, such work supporting l-i-or-ns have been provided .with a guard between 'Wl'Ll'C'l] and the'body of the hofrnthe thread pa-see to the usual whirl located in thin? tip .o;'t the horns Such guards have becninadcof a sin lepiece of metal and serve the pu )ose of protecting the lining ofthe shoe in (the wax thread as the latter is drawn throu the whirl during the sewing operation. In the event of thread breakage considerable inconvenience and delay has been heretofore encountered in reaching the broken end of a thread between the guard and the body portion in order to re-t-hrea-d the whirl, and usually in such instances the usual "practice has been to pry open the tip of the guard with a screw driver or other implement. This procedure resulted oftentimes in breaking off the tip of the guard, thereafter exposing the shoe lining to the wax thread.

The object of the present invention is to provide an improved horn for sewing machines in which in the event of thread breakage, ready access may be had to the end of the thread between the horn guard and the body portion of the horn, so that the whirl may be readily re-threaded. thus eliminating the breakage of the tips of the horn guards. h To this end the invention consists int-he work supporting horn for sewing machines hereinafter described and claimed.

In the accompanying drawings illustrating the preferred embodiment of the invention Fig. 1 is a vertical sect-ion of the im- I proved horn; and Fig. 2 is a front elevation of the horn guard.

The improved horn illustrated in the drawing comprises the usual upwardlycurrcd body portion .1 which is, secured to the usual base notshow in position to enter the shoe and support it during the saw ing operation. The body portion 1 is provided with a whirl 4 in the upper'end portion thereof of the usual construction, driven from the cam shaft of the sewing machine in the usual manner through a norm FDR snwme MACHINES.

pinion 6 on the upper endfof an inclined shaft 8, itself driven from a vertical shaftlO by cooperating gea1sl2 and 141.

; The body portion1of the horn is pro .vided with a guard 20 for protecting the lining of theshoe from. the wax thread as the latter passes upwardly between the guardaruil the body portion 1 of the horn on its ay to the .whi-rl 4;. In ,order to aiford ready access to the thread between the guard and body portion so that in event of thread breakage "theopcrator-may quickly and conveniently ireachthe end oft-he broken thread to re-thri-zad the whirl, provisionis made for permit-tinga. portion of the guardto ,be swung o-utvviardly from the body 3 ,portion ;of the guard. For this purpose the guard 20 ism-ade 'inntwo parts, a lower part 24 rigidly secured to the body portion 1 by screws 26 and anupper or tip portion 28 pivoted upon the upper end of the lower or stationary portion 2 1. The tip or upper portion 28 of the guard is provided with a tongue 29 which fits into a corresponding groove 31 in the lower or stationary portion 28 of the guard, as shown in Fig. 2. A pivotal pin 33 extends through the tongue 29 so that the tip or upper portion 28 of the guard is capable of pivotal movement outwardly about the pin '33 as a center. A spring 35 secured by screws 36 to the face of the lower or stationary portion 24 of the guard, bears against the upper or tip portion 28 thereof to yieldingly hold the latter in an operative position, as shown in Fig. 1, and to permit the tip or upperportion of the guard to be conveniently and easily swung outwardly.

The thread as it comes from the usual wax pot, not shown, passes between the guard 20 and the body portion 1 of the horn, entering through an eye 40 formed in a support 42 secured by screws 44 to the under face of the guard, as shown in F 1. The thread is led around a guide pulley 46 journaled in the support 42and thence over a second guide pulley 48 journaled in the upper end of the stationary portion of the guard and thence under the tip of the guard to the whirl 4:. I

From the foregoing description of the construction of the improved horn it will he breaks access is afforded to the broken end apparent that in the event that the thread restored to operation, in the event of thread breakage, with a minimum delay.

' While' the preferred, fornr the inven' tion contemplates the pivotal and yielding mounting of the upper or tip portion of the c guard, it is to be understood that viewed in its broader aspects the invention contemplates any construction of horn in which one portion of the horn guard may be swung outwardly to afford the desired access to the end of a broken thread.

Having thus described the invention what is claimed is:

1. A work supporting horn for sewing machines of theMcKay type having a body portion provided with a whirl, and a horn guard removably secured to the horn extending longitudinally of the horn between which and the body portion of the horn the thread passes to the whirl, the horn guard having 30 provision whereby the tip portion thereof may be swung outwardly with relation to the rest of the guard to afford ready access to the end of a broken thread thereunder.

2. A work supporting horn for sewingmachines of the McKay type having, in combination, a body portion provided with a whirl, and a horn guard removably secured to the horn extending longitudinally of the horn between which and the body portion of the horn thethread passes to the Whirl,'t-he upperportion of the horn guard being pivoted to the lower portion of the guard to enable it to be swung outwardly to afford access to the end of a broken thread thereunder. I

3.1x work supporting horn for sewing machines of the McKay type having a body portion provided with a whirl, a horn guard extending longitudinally of the horn under which the thread passes to the whirl, comprising a lower portion removably secured to the body portionof the horn, an upper portion pivoted to the lower portion, and a spring for yieldingly maintaining the upper portion in an operative position and for permitting the upper portion to be swung outwardly to afford access to a broken thread thereunder. r
