NEW JERSEY, A CORPORATION OF NEW MACHINE FOR OPERATING UPON BOOTS AND SHOES.

Specification of Letters Patent. Patented July 20, 1915,

Application filed April 29,1913. Serial No. 764,417.

To all whom it may concern Be it known that I, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex {and State of Massachusetts, have invented certain new and useful Improvements in Ma machines of this type which remove the last-' ing tacks from the path of the needle of the sewing machine.

It has been found desirable to bend certain of the lasting tacks in a lateral direction toward the inside of the shoe in order to remove them from the path of the welt needle, and the object of the present invention is to provide a machine having improved mechanism for bending the tacks inwardly toward the channel of the'shoe Without lifting them in the last.

lVith this object in view, the various features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the.

art from the following description.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 represents a side elevatlon of a machine embodying the several features of the invention in their preferred form; and Fig. 2 is a detail showing a section upon the line 22 of Fig. 1. v

The illustrated embodiment of the invention is shown in connection with a tack pulling machine of the type shown and described in the U. S. patent to McKenzie, No. 1,013,944, dated January 9, 1912. This machine is provided with a reciprocating tack pulling claw 1 rigidly supported on the outer free end of a jaw supporting arm 2 which is pivotally supported between its ends by a depending link 4 and has its opposite end connected to a crank shaft 5. The crank shaft 5 is continuously rotated from a drive shaft 6 through a suitable belt connection 7 The link 4 is fulcrumed at 8 secured to the machine frame.

upon a fixed portion of the machine frame and when the crank shaft 5 is rotated the tack pulling claw 1 is moved in a substantially elliptical path. Cooperating with the aw 1s a stat onary jaw 10 secured to the machine frame 11 and arranged to engage and support the tack against the thrust of the movable jaw 1. The tack is properly presented to the cooperating jaws and the shoe is held during the tack pulling operation by a guard 12 secured to the machine frame and extending into close proximity w th the stationary jaw 10. This mechanism is the same as that disclosed in the patent above referred to and in consequence, has been only briefly described herein.

The tack is bent inwardly by a hammer 15 detachably secured in the lower end of an arm 16 fulcrumed at 17 in a bracket 18 The bending hammer is operatively connected with the tack pulling mechanism and is continuously actuated through a lateral arm 20 formed integrally with the arm 16 and connected at its outer end to the jaw supporting arm 2 through a link 21. The tack is positioned in operative relation to the hammer by a. guide or downhold engaging with the upper of the shoe outside of the tack and provided with a tack engaging edge against which the tack is held to determine the extent of the bending movement imparted to the tack. In addition, the downhold is provided with a face extending transversely of the line of feed and operating as a stop to position the tack accurately in the path of the hammer. In the preferred form of the invention the downhold forms a gage for determining the angle of the shoe bottom relative to the path of movement of the hammer and insures that the tack engaging movement of the hammer is directed downwardly and inwardly with relation to the shoe bottom.

In the illustrated embodiment of the invention the downhold consists of an L-shaped plate 25 adjustably secured to an arm 27, which in turn is vertically adjustable upon the bracket 18 through a bolt and slot connection indicated at 19. The plate 25 is supported in an inclined position and the bottom face of the plate forms a gage against which the shoe bottom rests to position the tack in the proper operative relation to the path of movement of the hammer. By providing the combination of the two adjustments above referred to, the extent to which the tack is bent or the angle with which the hammer engages the tackmay be varied within the desired limits. From an inspection of the drawings, it will be readily observed that the tack is accurately positioned by the downhold with relation to the bending hammer and that the path of movement of the hammer when it engages the tack is so directed that there is no tendency to lift the tack from the last and the tendency to loosen the tack in the last is reduced to a minimum. In addition with this construction, as the downhold is located between the hammer and upper of the shoe there is no possibility of so manipulating the shoe that the hammer will contact with and mar the upper.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is i not essential except so far as specified in the mer arranged to engage with the side of a tack, a guide for positioning the tack in the proper operative relation to the hammer, and mechanism for actuating the hammer in a lateral direction to bend the tack away from the guide inwardly toward the channel of the shoe without lifting it in the last.

2. A machine for operating upon boots i and shoes, having, in combination, a downhold bearing upon the upper of the shoe outside of the tack, a hammer supported above the downhold, and mechanismfor actuating the hammer in a lateral direction above'the downhold to bend the tack inwardly toward the channel of the shoe.

3. A machine for operating upon boots and shoes, having, in combination, a hamhammer to bend the tack inwardly toward the channel of the shoe. I

4. A, machine for operating upon boots and shoes, having, in combination, a clownhold provided'witha face extending trans versely of the line of feed to form a stop for positioning the tack, a hammer arranged to engage with the side of the tack, and mechanism for actuating the hammer in a lateral direction to bend the tack inwardly toward the channel of the shoe.

5. A machine for operating upon boots and shoes, having in combination, an L- shaped downhold having a portion extending transversely of the line of feed of the shoe and a portion extending in the direction of feed and arranged for adjustment in two directions to vary the amount which the tack is bent and the angle with which the hammer engages the tack, a hammer cooperating with the downhold, and mechanism for actuating the hammer in a lateral direction to bend the tack inwardly toward the channel of the shoe.
