Application filed August 14, 1926. Serial No. 129,112.

This invention relates to stapling machines, and has special reference to stapling machines for use in the manufactureof shoes, whereby superimposed parts or layers of material may be secured together by staples.

An object of the invention is to provide an improvement in stapling machines for use in the manufacture of shoes whereby 10 superimposed partsor layers of material may be secured together by wire staples,

thus obtaining astronger. connection be-' tween the parts than has heretofore been obtained. Heretofore it has been a common 5 practice to secure together bystltching the parts or layers of material in shoesupon which the present invention is designed and constructed to operate. The stitching operations have been slow and tedious and the connections obtained did not possess thedesired strength to resist the strains to which the parts are subjected when shoes are worn. By the previous practice of stitching-the parts together the cost was large. My present invention overcomes these0bjections. and affords means whereby the parts or layers of material in shoesmay be firmly connected by wire staples, and where? by the wire staples are covered or protected on'the inside, so that they will not injure the stockings or feet of the wearer, and will also afford a strong and durable connection that will not separate under the strains and stresses to which the shoes are 85 subjected when worn.

The specific advantageous uses of the present invention is in the attachment of bows or. other ornamental attachments to shoes and, as herein illustrated and de- 40 scribed, it will be seen that the invention possesses all of the advantages and overcomes all of the difliculties mentioned and greatlyreduces the cost of manufacture of shoes. 7

Other objects of the invention will be apparent'from the following description, taken in connection with the accompanying draw ing, in which Fig. 1 is a plan view of the present invention attached to an operating part of a stapling machine of'known make, but which heretofore has notl been provided with any mechanism or device capable of application to the uses of the present invention.

. Fig. 3 is a view showing in section a part of-a'shoe in connection with the invention anda staple being driven through the superimposed parts or layers of material.

' Fig. 4 is a view showing'the lining of the shoe slitfor operation of the stapling machine. I

Fig. 5 is a bottom or reverse plan view of a shoeornament constructed to be stapled to the shoe by the present invention.

The known and existing stapling machine, on which the present invention isan improvement and parts of which are shown, comprises a staple forming and driving mechanism 1 from which the staples are successively discharged and driven through the material, through which the staples are applied, by a driver 2. The machine also comprises a supporting element 3 and, in the usual familiar operation of the machine, the driver 2 moves downwardly at the proper time to force the staples through the material and to. clamp the staples against an anvil.

'My present invention is designed and adapted to cooperate with these parts of the stapling machine and, as shown, comprises an anvil supporting element 4 having one end attached to the part 3 of the stapling machine and the other end provided with an. anvil portion 5 in alinement with the driver 2. g

The element 4 is bifurcated, approximately U-shaped in the specific form shown, having one arm attached to the support 3 and the anvil 5 attached to the end of the other arm. The anvil5 has a reduced por;

tion 6 extending into a hole in the ,end of the arm of the element 4 to which itis consign, is shown in Figs.

neeted and is releasably secured thereto by a screw 7. This permits removal and replacement and substitution of anvils 5, as may be desired.

A resilient plate 8 has one end releasably .connect-ed by screws 9 to the upper side of that arm of the support 4 to which the anvil 5 is connected. The plate 8 extends above the upper end of the anvil 5 and is shaped to provide a narrow and elongated depression 10. above the'end of the anvil 5. The side and end .walls, respectively, of'the depression 1O converge downwardly, so that when the ends of the staple passing throu'gh the parts or layers of material enter the de pression and contact with the inclined walls thereof, the ends of the staple are bent toward' each other and clamped against the material. The free end of the plate '8 is pointed to'fa cilitate the operation of passing the same through the slits in a shoe lining.

Suflicient shoe structure is illustrated to make clear a use of the invention in manufacture of shoes. As shown, the shoe comprises a vamp 11, a vamp double 12, a tongue 13,1a stay l t and a lining a number of chine to staple the ornament to the shoe the plate 8 is passed through one of the slits 16, the ornament backing 18 is placed upon the vamp 11 of the shoe across the plane of the slits 16, and the machine is then operated in the familiar manner of a stapling 7 operation forcing the wire staple 19 through the backing 18 and the superimposed vamp 11 and vamp double 12, causing the ends of the staple to enter the clamping depression 10, the inclined walls of which bend the ends of the staple toward each other and clamp them'upon the vamp double. The shoe is then withdrawn and the end of the plate 8 is passed through the adjacent slit 16, and the operation repeated. This securely fastens the ornament to the shoe, so that the ornament will not work loose or become detached when subjected. to the strains and stresses of wear, and provides a -constructionin which the lining shields and covers the clamped ends of the staples so that the staplesewill not damage orinjure the foot or'hosiery of the wearer. This operation may be performed quite rapidly, and in much. less timethan it has been possible heretofore to secure the bows or ornaments to the shoes, resulting in a large saving of time and cost. The lining and the vamp and vamp double may be attachedabove the slits 16, before securing the ornament 1'? to the shoe, by a line of stitching 20.

From the foregoing it will be seen that my invention accomplishes all-of its intendedobgects and purposes in a very sat1s-' factory manner; that the cost, of manufacture is greatly reduced due to i the considerable saving of time; that a better and more durable attachment of the ornament to the shoe is obtained, and'that ,theiusual lining islmade to servethe function-of a shield and protector to prevent injury to the foot and hosiery of the wearer.

The specific constructiom; arrangement and relationship of parts may be varied within equivalent elements, determined by the needs of the user and the operations to be performed. I contemplatesuch varia:-
