Thus the heel acts as a templet or pattern to control the trimming or heel-seat fitting operation. l i In the illustrated construction, a heel seat Before attaching Wood heels to shoes it is fitting machine is shown provided with asupusual to trim surplus stock from theperiphport for a loose heel, a gage member readily eral portionof the heel seats of the soles and manually movabletoengage'the heel,and`

As long as heel-seat fitting was performed by hand this was entirely a matter for the skill and judgment of the individual Workman, but now that heel-seat fitting is being done by machinery it has become important to provide mechanical means for insuring such an accurate control of the heel-seat iitting machine organization I0 and the presentation of the work thereto as will insure that each shoe is trimmed to fit the particular size of heel which is to .be attached to it.

It is accordingly an object of the present 35 invention to prov1de a heel-seat fitting machine organization having improved lmechanism for controlling the dimensions to which tlievheel-seat portions of the soles )operated upon are trimmed. With this` objectA in '40 view, a feature of the invention comprises means forpostioning a shoe during the performance of the heel-seat fitting operation and holding" it stationary, a measuring de vice operable to measure a dimension of the .This invention relates to machines for`use in the manufacture of shoes and is illustrated herein as embodied in`a heel seat fitting machine.

, The herein disclosed novel method in the"i of the general type disclosed in Lettersy Patent" of" the Unlted States' No.V 1,307,285, granted J Wentworthand F. H. Perry, is provided to correspond to those of the heel measured. with a drive shaft 10 rotated one revolution at a timeI by beltv 12` acting'through avoinerevolution clutch controlled by a 'suitable treadle. Cams on shaft 10.0perate the varions parts of the/machine according to a predetermined cycle. A lasted shoe is presented to the machine on a support 14 (or a shoe off the last may be presented thereto onfa support of the type shown in the above iden other, into the rand crease of the shoe, and

act to support the margin of the sole. These plates are pivoted on a slide or head 34,

which carries a cam roll 36 operated by a spiral cani '38, turned `by means of a handle 40 which is held in adjusted position by ,al-

lowing a spring pin to seat in one of a series of holes The operative position of support 14 is determined by engagement of the counter of a shoe thereon'with a gage 31, shown in Figs. 2, 3 and 4. In the patented machine the corresponding gage is mounted directly on the slide corresponding to slide 34. For

a purpose hereinafter explained, I have imjproved this construction by mounting counter gage 31 on a supplementary slide as shown in Fig. 4, arranged for adjust-ment longitudinally o f slide 34 by 'turning two adjusting screws 33, one of which is shown in that figure.

The central portion of the heel seat of a ,sole supported by plates 30 is depressed by a matrix roll 44, journaled in the forked end of a lever 46, and the waste marginal portion of the sole which remains above plates 30, is seve ed to form a U-shaped flap by a recipro'c ting knife 48 which follows closely.

after the forward motion of the matrix roll.

` The U-shaped flap so formed is cut oif at thebreast line by reciprocating knives 50.

The initial position vof matrix roll 44 is, adjusted simultaneously with plates 30 'and gage 31, and during the cycle of the machine the roll is picked up by the mechanism for reciprocating knife 48, and carried, forward from this variable initial position to auniform' yforward position such that .knife A48 cuts forwardly tothe breast line, lto cooperate with knives 50 inrmaking angularly'- related cuts vwhich remove ,the waste marginal stock. -l i,

All of the foregoing parts, and the i-actuating, mechanism therefor,may operate,.and'

are lllustrated as 'operating substantially like the corresponding 4parts described in thek above-identified patent, and no extendeddescription is here deemed necessary. Certain of these parts, however, are illustrated as improved in accordance,with the present in- Q with an abutment 62 in alinement with the breast-line position determined by knives 50. To.co-operate therewith, a gage or feeler 64 is mounted on slide 34 in alinement with' the rear end of the heel of a shoe positioned by gage 31. In operating u'pon styles of shoes in which the rear end ofthe counter is in alinement with the rear edge of the heel, abutment 62 and gage 31 will be set in substantial'alinement. In other styles, the position of gage 31V is so adjusted that the breast lineof a shoe positioned thereby will be in alinement with the breast vline of a heel engaged by abutment 62.

By this arrangement, when a heel is i,

placed on support 60 in engagement with abutmentA 62 and gage '64 is moved against the opposite side ofthe heel by setting slide 34 by means of handle 40, and when a jacked shoe von support 14 is swung'back as far as permitted by engagement of gage 31 with the counter, the breast-line position'determined by the junction of the cuts made. by knives 48 and 50 is automatically set to fit the sole for the particular heel being used as i a pattern. Thus the heel is made to serve as a pattern or templet and the shoe is trimmed to fit it. j

Some difiiculty has been experienced in trimming shoes having soles of comparatively flexible leather, in that such soles tend to buckle under the forward push of knife 48 and roll 44. To offset this, teeth 7() are lunA provided on plates 30, to hold the soles against slipping, and teeth 72 are cut on the ends of roll 44, to 'force the roll to rotate at the angular speed determined by rolling engagement of the teeth with the soles. As the center matrix portion 74 of the roll is of materially greater diameter than toothed portions 7 2, the-"angular speed so determined is sufficient to give matrix portion 74 a peripheral speed in 4excessof what would give mere rolling engagement with the work, thus wip'ng the work rearwardly and offsetting Ithe tendency to buckle.

I referto insure rotation of roll44 at the dbsired speed by mounting a pinion 76 on one end thereof, of'a diameter equal to portions This pinion engages a rack 78 secured at one end to slide 34 and supported at the other end by a hanger 80 on arm 46.'

v.To co-operate with the roll 44 in'hold1ng a sole, knives' 5 0 are brought 'into engage-,

ment with the sole during the forward movement of knife 48 and roll Then the ally knives`50 are again bron ht down to cutaway, the wastev stock. T is may be donexby an appropriate design'of cam 82,

Y. which acts through lever 84, link 86, and

slide 88, to provide this double reciprocation of knives 50.

I prefer to cause a correspondin double 'reciprocation of knife 4 8 and rol 44, so

that knives may-remain in engagement with the sole as long as ossible,knife 48 and roll 44 pausing whi e knives 50 are raised out of the way. This is done by'an appro riate designof cam 90, which operates t rough lever 92, link 94,-and rack 96, to reciprocate the slide which 'operates knife ,48. and fmatri-x roll i 1 l In o eration,,a .shoe is placed on support 14 an the corresponding heel on support 60, handle' 40 is turneduntilggagefG/l engages the heel, support 14jis swung back as far as gage 3l permits andfuntil plates 30 seatin the rand crease, and the-'one-revolu-` tion clutch is trippedrwhereup'on the shoe is trimmed to vfit the heel on support `6'0. I

When shoes such as turn "slices having sewed heel'seats are to be'operated upon,

gage 31 is notreally necessary as the lates `so may berelied upon aeanitly to position the shoes. vThis will be apparent when it -heel-seat will is considered that the'stitchmg around the rovideadenite abutment to receive the e ges of the plates 30.- `Many vwelt and McKay shoes, on the other hand,
