This invention relates to shoe machinery,
and particularly to an improved machine for cutting or skiving the heel end of-soles, the object being to provide a machine which will accurately skive the heel end of a sole, whereby it will be properly shaped.
Anotherohject of the invention is to provide a skiving machine for cutting the sides and ends of theheel portion of-the sole of a shoe, whereby this heelportion. will prop- I erly fit a wooden heel or other'heel of a shoe when the shoe is being completed.
r A further object, more'specifically is to provide a skiving machine for cutting the heel end of a sole in such a way that both the sides and oneend are properly chamfered.

' In the construction of shoes it is necessary to especially form the heel portion of the sole is a sectionalview through Fig 1928. Serial No. 291,344.
to properly receive the heel. This is particularly true in respect to wooden heels and in the present invention a machine has been provided-which at one operation slzives the heel portion of the sole in a substantially perfect manner. This skiving results in chanifering the edges of the heel portion so that the heel portion will fit properly against the wood heel. lVhen this operation is done by hand it IS quite often done inaccurately and poorly. so that certain adjustments and compensating additions must be made to secure a proper fit. In a machine embodying the invention the heel portion is always properly cut and consequently saves much time in the manufacture of the shoe. As shown in Figure 2, the machine embodying the invention is provided with a base structure 1 which may be mounted on any suitable support 2. Arranged on the base 1 is a platform 12 held in place in any desired manner, and straddling this platform is a yoke 3 having a slideway a for purposes hereinafter fully set forth. A pair of guideways 5 is also bolted or otherwise secured to base 1 and each guideway 5 provided with an upstanding bracket 6. A pin 7 extends through the brackets 6 a 1d through a lever 8 forpivotally mounting this lever, as clearly shown in Figure 2. Lever 8 at one end carries a con tact roller 9 bearing against the cam 10 and at the oppesite end is pivotally connected at 1! to sliding block 12 arranged in the head 3' oi olte 3. screw is connected with the block 12 4 head plate 1+1- so as to support the spring 15 acting'on the screw head 16. By reason of this arrangement spring 15 has atendency to keep the parts substantially in the position shown in Figure 2 with the knife 17 elevated. \Vheneverthe operating or large end 18 of cam 10 is acting on the roller 9 block 12 is forced downwardly so that the knife 17 will be moved in the position shown in Figures 5 and 7, whereby the cut or discarded portion CIA ' ders V in guide 5 but 19 of sole 520 is severed from the body of the sole. As shown in Figures 1 and 2 the solo is placed on the support or platform 12' with the trout or-toe end against the :rdjust able abutment or stop 21, whereby "he end ol portion of the solo will extend to Immediately after the roller passes the for- V ward end of the heel portion 28, us shown in Figure 5, knife 1? will move downwardly to ou off the portion 19 as it cuts the shoultion'oi the skived heel portion 28, as shown in F gure 8, thus pernntting the sole 20 to be manually removed and s new one substi vtuted. After the new one his been substituted the some operation is performed and so on as long as the machine is in operation.
As shown in Figure 6, the die 2-3 is provided 'withroughened portions 31 which prevent the sole from slipping during the cutting oporation. The roller 24 by reason of its mounting has a very limited or slight resilient ac,- tioh and consequently can be readily forced overthe end 22 end then moved, as shown in, Figure 3, for depressing the center of the sole. As shown in Flgures l and 2- the roller 24 is mounted on a yoke 32 which is screwed, riveted or otherwise rigidly secured to e sliding .plete 33 slidably mounted in the guide or runwaysS. The plate 33 iits rather snugly allows a very slight resilient ction in order that the roller 24 may pass over the end; 22 also curries the knife 27, which is Yrernovably' secured in pliice by screws; A block 34 is pivotelly connected with-the plate 33 by pinBS si-iid' bloclc halving a threaded bore 36 for receivingone end of the screw 37, the opposite end being threaded into'the enlarge.-

When the machine is operating the sol'e'piece indicated by 20 is placed on the plzitformlQ end the lever l9 is lowered. This lever carries a presser foot 50 which presses against the sole near the end of die 23 and thereby holds the sole inposition' while the roller-2 L functions The presser foot 50'may be held inoperative position by the-weight of lever 49 or'if dcs ired, additional removable 'wei hts maybe used or merelythe pressure of the hand of the operator.
