JOSEPH VERTUNNI, F LONG BEACH, CALIFORNIA.

HEEL-CUTTER.

Application filed February 28, 1916.

To all whom it may concern:

Be it known that I, JosnPH VnR'rUNNI, asubject of the King of Italy, residing at Long Beach, in the county of Los Angeles and State of California, have invented a new and useful Heel-Cutter, of which the followin is a specification.

My invention relates to the art of shoe repairing.

The principal object of the invention is to provide a machine which will cut ofl' the worn portion of shoe heels preliminary to placing new lifts on such heels. In the art of cobbling the replacement of heels 'is a common occurrence, and it is necessary in such replacement to remove a portion of the old heel which is ordinarily secured by nailing. Various devices have been developed which would cut through the leather of the heels and the nails which secure them in place, cutting the heel oif squarely so that any lifts could be readily attached thereto. My invention provides an improved machine for doing this, embodying in such ma chine all the desirable features of previous machines, and combining these features with certain new features in such a manner that a new and improved method of operation will be secured.

Further objects and advantages will be made evident hereinafter.

In the drawings which are for illustrative purposes only: Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is side elevation of the same machine. Fig. 3 is a plan view on an enlarged scale of the table of the machine with the various parts attached thereto, the shoe shown in the other views being omitted. Fig. l is a section on the line w w" of Fig. 3, looking in the direction of the arrows. Fig. 5 is an enlarged view of the shoe securing means.

In the form of my invention illustrated in the drawings, 11 is the table of the machine, this table being secured on a standard 12, which extends down and may be secured to a floor 13. Journaled in the standard 12 is a driving shaft 15 provided with a tight pulley 16, and a loose pulley 17 for the reception of a driving belt, not shown. Mounted on the overhanging end of the shaft 15 is a driving wheel 18. Secured to the top of the table 11 is a bracket 19 having a slotted head 20 in which a shaft block 21 slides, this shaft block being adjusted up and down by means of a screw 22. Secured Specification of Letters Patent.

Serial No. 81,047.

on the shaft block is an idler shaft 23 on which an idler wheel 2% is free to turn, the idler wheel 2% being in the same plane and directly about the driving wheel 18. An endless band saw 25 passes over the wheels 21 and 18, passing through saw recesses 26 and 27 formed in the table 11, and having its teeth projecting in the direction of the arrow A. Guards 28 and 29 partially cover the saw 25, and prevent the operator accidentally coming in contact therewith. Guides 30 are formed in the table 11, and a lower slide 31 is mounted to slide freely in these guides across the table in the direction of the arrow 32. Guides 33 are formed in the top of the lower slide 31 extending in a direction at right angles of the guides 30, and an upper slide 3d is mounted to slide in the guides 33 in the direction of the arrow 35. An extension 36 is formed on the lower slide 31, and a handle lever pivot pin 37 extends upwardly therefrom. A handle lever 38 is pivoted on the pin 37, this lever having an extension 39 with a slotted hole 40 in the extreme end thereof, the slotted hole 40 engaging an upper slide pin ll which is fixed at the rear of the upper slide. A screw 12 is rotatably secured in the eX- tension 43 formed in the side of the table 11, a hand-wheel 1d being secured to the extreme end thereof by which the screw 42 may be actuated. The screw 12 extends between the guides 30 and is threaded into the lower slide 31.

or the purpose of securing the shoe, a lower block is formed on the upper slide 3 1-, and an extension arm 51 is provided extending up and over the block 50, being provided with a projection 52 in which a lever 53 is pivoted on a pin 54. An operating handle 55 is formed on the front of the lever 53, and a latch 56 is provided, this latch being forced into engagement with teeth 57 formed on the extension arm 51. A spring 58 tends to force the latch 56 into engagement with the teeth 57. An upper block 60 is secured to a standard 61 which has a slotted hole 62 formed in the top thereof, this hole being engaged by a pin 63 carried by the lever 53. A compression spring 64 tends to force the block 60 against the heel of the shoe 71.

The method of operation is as follows: The driving wheel 18 being rotated by means of a belt on the pulley 16 through the shaft 15, drives the band saw 25, this saw passing continuously around the wheels 18 and 2 1. The operator places a shoe 71 on the upper slide 34 with the heel resting on the lower block 50, the upper portion of the heel being clamped in place by the upper block 60. To further secure the shoe the operator presses down on the handle 55, the latch 56 engaging one of the teeth 57 and securely locking the block 60 in place on top of the heel 70. A graduated scale 80 is provided on one of the guides 30, and the lower slide 31 may be adjusted back and forth in the direction of the arrow 32 by means of the hand-wheel H. The saw recess 27 is of sufficient depth to allow the saw to extend well into the body of the table 11. The operator manipulates the hand-wheel tt to move the heel to its proper position in front of the saw, the amount of such movement being readily gaged on the scale 80. WV hen the heel is in the proper position, the operator seizes the lever 38 and draws it in the direction of the arrow 91, this causing the upper slide 34- to move away from him in the direction of the arrow 35, and

to pull the heel 70 against the saw 25, this saw cutting through the leather and nails of the heel to produce a firm and level foundation for new lifts.

I claim as my invention 1. A heel cutter comprising a table having saw open recesses indented at either side thereof, said recesses extending laterally of the saw blade out through the side edges of the table, a driving shaft journaled below said table, a driving wheel mounted on said shaft outside its bearings, an idler shaft, means for supporting said shaft above said table, an idler wheel on said shaft, a band saw mounted on said driving and idler wheels and passing through said saw recesses in said table, a lower slide mounted in guides on said table in such a manner to slide across said table in a direction parallel to the plane of the band wheels, screw means for adjusting the position of said lower slide, an upper slide mounted in guides on said lower slide in such a manner as to slide in said lower slide at right angles to the direction of motion of said lower slide, means by which an operator can cause said upper slide to move in said lower slide, and means for securing a shoe to said upper slide in such a position that said movement of said upper slide in said lower slide throws the heel of said shoe against said saw.
