sHOE BEPAIR MACHINE.

The invention'relates to shoe repair machines, especially adapted for use in shoe repair shops. i

7 An object .of the invention is to provide a simple and eifective machine for severing the stitches in the edges ofa shoe -sole pre'paratory to repairing the same.

Another object of the-invention is to' provide such a machine capable of manual manipulation.

Another object of the invention is to provide a simple. and effective machine for this purpose which is capable of economical production.

Another object of the invention is toprovide such a machine capable for use inmaking ornamental stitch impressions in the edges of a shoe sole;

Other objects and vention will appear more The invention consists in the combination and arrangementof parts and in the'method of procedure hereinafter described and claimed.

In general the objects of the invention are attained by providing a'revolving table and a cooperating feed wheel adapted to 'engage the edge of a shoe sole on said table and intermittently feed the same by revolving said shoe and table. Co-operating with said table novel features of the inand feed wheel is a reciprocating knife ar-' ranged to sever the stitches in the edges of the shoe sole as it is thus fed to'the knife. Attachments are also provided whereby a knurled or serrated impression wheel may be readily mounted on said feed wheel and a yielding revolving table substituted for said first mentioned table, means for yieldingly pressing said yielding table toward said impression wheel being also provided, whereby ornamental stitchimpressions may be made in th'e'edges of a repaired shoe sole if desired.

The invention will be best understood by accompanying drawings forming a part of this specification, and in whichi Fig. 1 is a side view of a machine embodying the invention; 3 i

Fig. 6 a detailview of the feed wheel. of

the machine and co-operating parts;

Fig.7 a view similar to Fig. 3 but show-- ing a modified form of construction, and

g. 8. a section. taken substantially on line 8-8of Fig. 7.

The form of construct on illustrated Figs. 1 to 6 inclusive comprises a suitable base or standard 10 having'a hollow supporting boss 11 formed integrally therewith. A supporting stemor stud shaft 12 is removably secured in the top of the boss 11 by means of a set screwv 13. A revolving table 14 is mounted upon ball bearings 15.011 the top of the stud shaft 12 andwhereby said table, will readily revolve in a slightly inclined position as best shown in Fig. 2. I I I A suitable frame 16 is pivoted at- 17 on two supporting lugs 18 on the base 10, a suitable stop 19 being'provided on one of said lugs 18 to limit the backward swing of said frame in .one direction. At its side opposite the pivot 17 the frame 16 carries a swinging and sliding bolt 20 slidable in a pivoted bracket 21 and carrying an I adjusting handle 22 threaded thereon to adjust the tension of a compression spring 23 as indicated The bolt 20 carries a hook 2 1 adapted and arranged toengage teeth on av lug 25 on the base lO and whereby the frame 16 may be adjustably and yieldingly, locked inoperative relation with the revolving table 14.

Mounted carrying a head 27 having a knurled. conical feed wheel 28 mounted thereon in co-operative relationship with the edge of the table 14:. The arrangement is such that the frame 16 in the frame 16 is a shaft 26 may be readily adjusted to cause the feed wheel '28 to engage the edge of a shoe sole 29 on the table lt'and feed said edge of said shoe sole by revolving said table as will be readilyunderstood. The shaft 26 carries a ratchet wheel 30 co-operating with a ratchet arm 31 loose on the shaft 26 and carrying a spring held pawl 32 enga 'ing said ratchet.

The pawl arm 31 is given a slot and pin connection 33 with one end of a lever 3 1 fulcrumed on the frame 16 and having its other end connected by a link 35 with a crank pin on an adjustable block 36. The block 36 is readily shdable in a radial slot 37. in a wheel 38 and is adjustable in said slot by means of an adjusting screw 39 as best shown in Fig. 5. The wheel 38 is mounted on a shaft I 40 connected bya gear 41 also on shaft 40 with a gear 42 on a crank shaft 43 operable by means of a hand crank 44 and whereby adjustable movementmay bereadily imparted to the feed wheel 28 and the shoe sole 29.

The gear 42 also meshes with a gearf45 on a shaft 46 in frame 16. Shaft 46 carries a crank pin 47 connected by a crank 48 with the upper end of a reciprocating plunger 49 mounted in a bearing on the outer face of the frame 16 just above the feed wheel 28. A severing knife 50 is removably mounted in v the plunger 49 to operate immediately adjacent the side of the feed wheel 28. By this arrangement it will be apparent that a shoe maybe readily placed upon the table 14vand the edge thereof engaged by the feed wheel 28. Upon operation of the crank 44 the edge of the shoe sole will be intermittently fed step by step under the knife 50 and said knife will be caused to impinge upon and sever the threads 51 in the edge of said shoe sole. By adjusting the block 86 in the slot 37 the extent of the feed of the feed wheel 28 may be varied for different styles of stitches. In this way, it will be noted, that the stitches in the edges of a shoe sole may be readily severed and the sole removed for repair purposes.

In the modified form of construction illustrated in Figs. 7 and 8, I have provided attachments whereby the machine .may be readily used for making stitch impressions in the edge of the sole after a new sole has been applied. To this end a revolving table 14 is provided with a stem 12, smaller than before, and adapted and arranged to reciprocate freely in the opening in the boss 11. Arranged in the boss 11 is a lever 52 pivoted at 53 and projecting through a slot 54 at the side of said boss. 7 52 is connected by the compression spring 55 with pressure arm 56 on a lever 57 fulcrumed at 58 on one of the lugs 18 and whereby the table 14 may be yieldingly pressed, upwardly by exerting manual pressure on the lever 57. A hollow fluted or serrated impression Wheel 59 is providedwith a hub 60 arranged to removably engage the head 27 on the end of shaft 26, a set screw 61 I being provided for securing said impression wheel in place. By this arrangement it will be observed that the knife 50 may be removed and a table with the sliding stem 12 substituted for the permanently mounted table, and an impression wheel 59 mounted upon the head 27, as shown in Fig. 8. When so equipped the edge of a shoe sole 29 may be placed on the table 14 under the impression wheel 59 as indicated in Fig. 8 and ornamental stitch impressions formed in the edge of the sole after the same has been repaired.

It will straighten a sole when wet and also draw the sole away from the upper to The other end of the lever straighten it after nailing a sole to the upper.

While a preferred embodiment .of the in-. vention has been illustrated and described, this is capable of variation and modification without departing from the spirit of .the invention. It is, therefore, not desired to limit the patent to the precise details disclosed,

but to include therein such variations and modifications as fall within the scope of the appendedclaims.
