9 Claims.

This invention relates to shoemakers' tools, and more particularly to a manually operated cutting tool particularly adapted for severing the rear of the front sole of a shoe preparatory to removal of said front sole and applying a new half-sole thereto. i

In the past, before applying a half-sole to a shoe, it was customary for the Shoemaker to remove the worn front sole by peelingf it from the front or toe end toward the heel, and `then making a cut crosswise of the shoe adjacent the instep portion with a knife. Thev cut so made was generally somewhat inclined requiring the shaving of the new sole to a thin `beveled edge. The fit between the inclined surface of the remaining portion of the old sole and the thin beveled edge on the new sole was often uneven and unsightly, causing the new half-sole to loosen and spring apart at the joint lduring the subsequent wearing of the shoe.

One object of the present invention is to provide a shoemakers hand tool of the above nature in which the above and other disadvantages have been overcome. This has beenjaccomplished by the provision of a novel iormof sole cutting tool which is adapted to permit the Shoemaker to sever the rear endof the. worn front sole transversely at the instep with a single rectangular cut forming a square shoulder to which a similarly formed new half-sole may be readily tted and eiciently secured. y

Another object of this invention is to provide a shoemakers tool of the above nature Ahaving means to rmly clamp the tool to the shoe while the transverse cutis being made, and in which the rectangular knife will make a Vertical cut and a forwardly extending inclined cut simultaneously in one motion ofthe' tool transverse to the axis of the shoe.

A still further object of this inVentiOn to provide an improved shoemakers sole-cutting tool of the abovenature which will be relatively inexpensive to manufacture, simple in construction, compact, and very eicient and durablein use. .v

With these and other obects in view, which will appear as the description proceeds, there have been illustrated in the accompanying drawings two forms in which the invention may be conveniently embodied in practice.

In the drawings:

Referring now;A to the drawings,v wherein ylike reference numerals. indicate corresponding; parts fthroughout. the several views the numeral l`It) denotes vtheupper.` end of a shoeftree rwhich is e215 adapted to receive and `support `a sl,1oe 25. `v The m shoe `tree Ill is adaptedto have, its.,l0wer` end seatedin a .flat base (not shown) whereby Lthe 'shoe-to be half-soled maybe located .in agconvenient position/close to ythe shoemakersiseat..f- ;0 The shoetree Ill has a laterally extending lug. I `protruding from fone side thereof,"which lug I I,v lis provided with a hole I2.in its outer end' for a purpose `to be later described. The improvedshoemakers to'ol of this invert-@55 tion comprises a frame I3 .of arcuate forni, ha'v- .ing upstanding end plates I4 an d|5l.` an upstanding side ilange I6, and a depending., sid-e ange I'I. i In order to detachably lock thairame I3.i n the operatingV position shown in'1ig."1, ;40 provision is made 'of aL bracket, I9 secured Vto the end plate I4, as byscrews I8,said.bracket having a slot 20 through wl'lichr an elongated depending bolt 2| may pass. The bolt 2| has a hook portion 22 at its lower end adapted to be. 45 engaged in the hole I2 in the lug II. The bolt" "2 I` isscrew-threaded at its upper end'to permit a thumb' nut 23 to be screwed downwardly .against the bracket I9, which serves as a fulcrum for holding the frame I3 in operating position 50v upon the sole 24 of a shoe 25 supportedupon theshoetreel. t

In order to permit the .opposite end of the frame I3 to be manually held down by the shoemaker, provision is'made of a handle 26 riveted 55 vto a bracket 21 which in turn is secured to the end plate I5, as by screws 28. The handle 26 extends awayfrom the frame I3 and may be used to hold the frame flange I1 downwardly upon the shoe sole 24 as indicated in Fig. 1.

To prevent slipping of the shoe 25 laterally .with respect to the shoe tree I0, the tool is provided with a pair of laterally spaced-apartl dependingspikes o r points 29 and 30 formed on the lower endsof a pair of threaded studs 3| and 32which studs are adjustably screwed into the bottom-wall 33 of the frame I3 and are Ylocked in place by lock nuts 34. The studs 3I and 32 normally extend below the downwardly extending side flange I1 tol 'cause the spikes 2:9 and to' become slightly embeddedin the sole 24 before the flange I1 engages the same.

In order to more rmly attach theshoe 25 upon the shoe tree I0, provision is made of anl angular` clamping pad 35,v covered with leather 36,v and extending 'dqwnwardly along one yside of said shoe-tree'l. The pad `35 Ihas an inclined f lateral prjection which is pivotally secured --by a srew 3s to attacker 39 which' in turn is 25 secured to and eX'te'r'ids "aeross the bottom wall 33 fthe frame fm yaiiacenx; tothe vena plate I4.

By means ofy this construction, the pad 35 may be `swung to adjust itsel yto the agularity of the shoe 25 where it contacts the saine.

The bracket 3`9Uekten`ds rlaterally beyond one side of the ,i`ram'em|j'3 andhas va portion -40 (see Figwfi) bent upwardly' and backwardly over itself to Yifo'rr'nja 'taperedprotective guard for the Y hcrizontalwcuttingf, blade portion 4I rof a cutting kni`fe j42. Theeutting'knife 42 further includes a vertically disposed vcuttingblade portion f 43 tion 4'I.- The blade portion 43 i-s provided with an upper vertical shank portion 4.4, which is adaptedto be adjust'ably received in `a vertical dvepro-vided in the ziront face of a slide "..arfd hdirectlyYazijajce'ntthe .blade portion 4I `by niean'sof 'a eurved'at tongue 49 formed on the lower edge of the "clamp plate 41 (see Figs.

The

carrier v (Fig. 3) has a side wall lSI spaced fro-rn the verticali-partition 53 and which extends downwardly from.`itstop wall 58 to embrace an arcuateupper. guide ra`-il 62 .Whichextends from th'e end Yplate I4 to ithe end plate I5 f the'frarne I tree. I0.

I0 and is secured thereto by screws 63 (Fig. 4). Disposed between the partition 53 and the wall 6I, and journaled on studs 64 are aplurality of horizontal friction-reducing rollers which ride on the upper and lower edges of the rail 62 to guide the carrier 50' and the cutting knife 42 transversely across the shoe sole 24.

For the purpose of frictionally retaining the carrier 50 adjacent the end plate I4, in which position the horizontal cutting knife blade 4I is lo protected by the tapered guard portion 40 of the vbracket at the end of the cutting stroke, pro- Vision is made of a catch leaf-spring 66 secured at "one end to the vertical side flange I6 by a screw l69. AThe spring 65 has a forwardly convex 15 ifree end 61 which is adapted to engage a head 68 of one of the roller studs 64.

Modified form The modified form of the invention shown in 20 Fig. 7 differs from the first form described above by having a pair of sole-engaging pointed teeth 1D andI corresponding to the spikes 23 and 3Q, supra, located Yon the under surface of a bar 12 which is pivotally secured by a bolt 14 to the 25 frame side iiange 13, corresponding to the above dt-scribedv side ange I6. Inthis manner, the teeth 10 and 1I 'are permitted to adjust themselves kso as to uniformly penetrate into the surface of a shoe sole 24 of uneven thickness. "30

A horizontal handle 15, corresponding to the handle '526 'of the previously describedV form, is in vthis instance pivotedl by a bolt 1B to a lug 11 extending from a frame endplate 13, correspondring to the frame endvplate I5, supra.v A curved *35 extension 19, which is integrally joined to the handle `15, is adapted to engage the side of the shoe25 and clamp it to the shoe tree Il! `and to simultaneously draw the clamppad 35 tightly# against the other side of the shoe 25.

'Operation V`rear extremity 84 of the ysole 24 may then be readily lifted therefrom, and gripped by pliersq.,

not shown, to facilitate the peeling of the old 5'0 sole forwardly from the' shoe. Itl will be understood that the vertical shoulder 8f] and the inclined cut82 will be severed in one operation of the tool rapidlyand eciently.

It will also 4be understood that prior to theg5 operation just described, the shoe 25 will be placedon the shoe tree I0 in the usual manner with the hook end/220i the elongated bolt 2| vengaged in the -hole I2 of the lug I I, and the thumb-nut end'swungfthrough the slot`2ll in the-"60 bracket I9. The thumb-nut 23 maybe tightenedthe desiredamount, and the-frame I3 will be :swung downwardly over the shoe sole 24 by the horizontal handle 25 (or 15) to cause theVM -DOintS 29 and 30 (or. 10 and 1I) to become ern-65 bedded vin ythe leather sole 24,- the iiange I1 Ialso engaging the sole to hold it rigidly upon the shoe After the sole has been out, .the tool is .then raised again away from the shoe 25 and shoe '7o tree I0, andthe worn half-sole stripped orpeeled off `as describedabove.A .A new vhalf-sole may then be readily attached to the shoe by nailing,

stitching, cementing, Yet 'vc.,-a smooth and more durable joint being produced at the rear of the"'7`5 ha1f-sole than could be produced by previous methods and tools. y

While there have been disclosed in this speci` cation two forms in which the invention may he embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the speciiic disclosures, but may be modied and embodied in various other forms without departing from its spirit. In short, the inven tion includes all the modiiications and embodiments coming within the scope of the following claims.
