' LIP TURNER.

Application filed November 24, 1924. Serial No. 752,020.

This invention relates to lip turners yand is particularly directed to a lip turner adapted to operate upon marginally split innersoles such as that disclosed in `our copending application, .tiled November 24, 192/1, Serial Number 752,021, for inner soles ilor stitched down shoes. A A

InA formi-ng in-ner soles of the type disclosed in our copending application, it is necessary to turn a very thin lip which has been slit from the body portion of the sole and in turning thin lips of leather` or similar material extreme diliculty has been experienced, and with fthe 'formerly constructed machines, this operation has been impossible. v i

Objects of this invention are tol provide a lip 'turning machine adapted to de'liect and turnthe lip eta marginally slit stripol:

" leather or similar material, to provide a ma chine `which will rapidly separatethe relaA tively thin lip from the body portion of the material, and which will told the lip over againstthe body portion and firmly rpress it into position in a rigid and efficacious manner. y

Further objects are to provide an extremely simple compact machine for folding the lip ot marginally slit inner soles, in which the machine aids in the feeding ot the inner sole, and in which yielding means areL provided for holding the inner sole in position while it is being fed, andl tor pressing the lip downwardly into place.

An embodiment of the invention is shown in the accompanying drawings, in which z- Figure 1 is an elevation of the' machine partly in section.

Figure 2 is a. transverse `sectional view lon the line 2-2 of Figure 1.

Figure 3 is a fragmentary view of the lower portion of the rotating members with the sleeve and sole shown in section showing the folding arm in one position during its rotation.

Figure 4 is a corresponding view showing the arm in another position.

The machine comprises an upright standard 1 extending 'from a basepplate 2. This standard is provided with bearings Jiior the rotary shaft and sleeve. In the form shown three bearings 3, l1 and 5 areillustrated, al-

though, obviously, the exact details ot construction maybe varied. The bearings Il and 5 slidably and rotatably carry a sleeve which is provided" with a driving vpulley 7 at its upper end and with al collar 8 inter- V mediatethe bearings l and 5.v Ahelical` spring k9,llooselysurrounds the sleeve and `bears at one end against the collar'A and at the other end against the bearing fl. A shaft 10 extends the entire length of the machine and passes` through the 'hearing 8l and through the sleeve 6. lt is provided with a driving pulley 11 at its upper end and with a collar 12 intermediate the bearings 3 and 4l. A spring lloosely surrounds the shaft! and bears at one end against the collar 12 and at its other end against, the hearing 8. p Y i l The lower end olifthe shaft 1() vis provided with a! circular disk lll and the lower end ot the sleeve 6 is provided witha radial tolding arm Any suitable means. not shown, may be provided 'for raising the `shaft 10V and the sleeve 6 during Vthe positioning ot the work.

In usingrthe machine the marginally slit sole 16 is positioned upon the base plate 2 and theqdisk 14e is positioned between the lip 17 and the projecting port-ion 18 et the body of thevsole. The spring 13 forces the shaft downwardly and holds the marginalportion 18 ofthe sole in closecontaet with the hase plate 2. Itis to be particularly noted that Lthe shaft 10 and the sleeve G are rotated in opposite directions, as shown by the arrows in Figure 2. The disk la rotates in' a man'- ner to aid the feeding of 'the sole, as illus trated in Figure ,2, and the radial arm 15 sweeps around in areverse direction and folds the lip 17 over tightly against the body portion, as shown clearly in Figure 4s. The radial arm merely slides oil the undeected forward portion ot the Vwork when in the opposite position from that shown in Figure 2. s y y It is to be noted that the springs 9 and 13 hold the disk 1li` and the arm 'l5 closely against the work and compensate for any irregularities in the work.

. This machine can operate at a very rapid rate and the work can be quickly fed through the machine with assurance that the very 'thin lip 17 will ybe accurately folded into position, as shown yin Figure Al.

'It will further befseen that an extremely simple and'substantialtype oit machine has been provided which, although of simple construction, nevertheless electively perlit) liorms the relatively diiiicult operation of separatinand folding the thin lip over against the body port-ion.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously enibodied and is, therefore, to be limited only as claimed.

Vile 4claim l. A machine tor turning the lip ot split material comprising positively rot-ated means for separatinfr the lip trom the body of the material, and other independently, positively rotated means tor folding said lip over against saidbody, said last mentioned means being rotated at a` higher speed than said lirst mentioned means.

2. A machine for turning` the lip oit split material comprising rotary means tor separating` the lip from the body ot the material and reversely rotating' means for tolding' said lip over against said body portion.

3. A machine for turning` the lip ot marginally split leather comprising a rotary shaft, a dish carried by said shaft and adapted to deflect the lip from the body portion o1 the leather, and a reversely rotating sleeve mounted upon said shaft and yieldingly body portion.

5. A machine tor turning the lip of a marginally split leather member compi-ism@T a standard having a base plate against which the body portion ot said leather rests, a

vertical shaft carried by said standard and terminating in a circular disk at its lower end adapted to enter the slit and vdeflect the lip upwardly, yielding means :tor pressing` the disk against said body portion and holding said body portion againstsaid base plate. a reversely rotating sleeve loosely mounted upon said shaft, resilient means urging said sleeve downwardly towards said disk, and a radial arm carried by the lower end ot said sleeve and adapted to engage the upturned lip and fold it over against said body portion, said rotating disk aiding in the 'feedingv of the leather.

In testimony that we claim the toreseoinf; we have hereunto set our hands at lVausau. in the county ot Marathon and State ot Wisconsin.
