2 Claims.

This invention relates to new and useful improvements in stitching awls and has particular reference to a shoemakers stitching awl for producing a lock stitch in the welt, upper and insole of a shoe and is especially useful in repair work wherein it is desired to securely stitch these parts of the shoe together by hand.

The principal object of the invention is to provide a compact awl for the purpose of producing a lock stitch in shoes which embodies a bobbin and a needle so arranged as to enable the shoemaker to quickly and easily stitch the welt, upper and insole of the shoe together in a most effective manner.

Another object of the invention is to produce a stitching awl of the class designated that is extremely simple in construction and that is most effective in operation, and onethat saves time and labor for the shoemaker in hand repair work.

A further object of the invention is to produce a stitching awl of this character that includes a bobbin which folds into the handle of the device when the awl is in operation and that may be readily swung out of the handle for rethreading 25 purposes.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals 30 are employed to designate like parts throughout the same,

Fig. l is a bottom plan view of a shoe with the sole removed and illustrates the method of starting the lock stitch through the welt, upper and 35 insole of the shoe,

Fig. 2 is a plan view of the stitching awl showing the hollow handle section, bobbin and needle set into the end of the awl,

Fig. 3 is a side view of the same partly in sec- 40 tion and illustrates the bobbin recess with the bobbin in operative position therein and further illustrating the hooked needle of the device,

Fig. 4 is a sectional view of the welt, upper and insole of ashoe and illustrates the method of 45 using the awl in producing the lock stitch, and

Fig. 5 is a diagrammatic view showing the completed lock stitch through the various parts of the shoe.

In the shoe repairing trade it is often desirable 50 to repair the soles of shoes by hand in that shoe machines are not always available for this purpose and, besides, handwork of this character is,

bobbin for carrying the thread, which bobbin is handily arranged in the handle of the device to feed the thread while the awl is in use in producing the desired lock-stitch.

Referring to Figures 2 and 3, my improved awl consists of a handle section 6 having a recess 7 formed therein, said recess being open at one side as indicated by the numeral 8. A slot 9 is formed in a portion of the handle and accommodates the looped end ll] of the bobbin H, which bobbin may be formed of wire and may be swung on its pivot l2 out of the recess 1 by means of a handle l3. It will be noted that the enlarged or looped section of the handle I3 serves to retain the thread on the bobbin II and to normally keep said thread from unwinding therefrom except when an additional section of the thread is required in the stitching operation of the awl. In the operation of repairing shoes the thread I4 is threaded through a perforation H) in the end of the handle and a section thereof is wound about the bobbin, said bobbin being swung out of the recess for this purpose. An elongated neck section I6 extends from the handle and is provided with a needle socket ll into which the shank of the needle I8 is fitted which needle is securely held in place by means of a small set screw l9 tapped into the section IS. The needle I8 is comparatively sharp at its outer end and is provided with a hook 20 for the purpose of drawing the thread through the shoe parts as hereinafter more fully set forth.

In the art of repairing shoe soles the worn sections are first stripped away, and as indicated in Figure l, the welt 2! is then app-lied tothe edge of the upper 22 and to the insole 23. The awl needle it is then forced through these parts and aloo-ped section 24 of the thread is placed in the hook 20 of the needle and the awl is then drawn out through the shoe, carrying with it the looped thread, as clearly shown in Fig. 1.

The awl is then inserted through this loop carrying with it the continuous thread from the bobbin and the loose or slack section of the thread is then drawn taut to draw the loop against the welt which operation forms a section of the lock stitch. This operation is repeated by inserting the needle through the shoe and drawing the thread through the. various parts thereof, the spacing of the stitches about the shoe being accomplished by virtue of the trained eye of the operator.

It will be noted that the section I6 is provided with an extension I9. This particular extension In Fig. 4 I have illustrated diagrammatically the operation of the awl in forming the lock stitch and in Figure 5 the completed lock stitch has been shown.

It is to be understood that the form of my invention herewith shown and described is tobe taken as a preferred example of the same and .that various changes relative to the material,

size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a device of the class described, means for producing a lock stitch in shoes, comprising a handle section having a recess formed therein, a pivoted bobbin arranged to swing into and out of said recess, and a hooked needle arranged in one end of said handle and adapted to produce the looped section of said lock stitch.

2. A device of the class described for producing a lock-stitch through the welt, upper and insole of shoes comprising a handle having a recess formed therein, a pivoted bobbin adapted to swing into and out of said recess for carrying the stitching thread, said bobbin having a looped end, and a stitching needle embodying a thread engaging hook for producing the loop sections of said lock stitch.
