This invention relates primarily to machines for operating upon soles. The invention' is illustrated as embodied in a machine designed for providing an insole with positioning surfacesto be utilized in shoemaking operations.

Ina co-pending application of thepresen't' applicant filed February 12, 1925, now Letters Patent No.'1',674 ,O60, granted June 19,1928, I isdisclosed a method and, a machine relating to the lasting of the toe offa shoe, a characteristic of which is that'a last andinsole are each provided with a plurality'ofpositioning sur-;

' faces in spaced locations, preferably provided by positioning holes, by'theuse'of which-the v insole, the last and the shoe upper materials,

which are to be shaped thereon, may be posi-- Y tio'ned quickly and accurately in relation'to lasting devices of a lastingmachine j'JAn lmportant object of'the present inveni tion is t o "provide a machine-particularly adapted for. use in preparing such an insole which positioning' holes may be formed in; an insole in definite, predetermined relation! to the edge contour of the insole and also, in the case of a welt insole, .to'the insole rib and preferably in relatively close proximity to the rib.

' To this end, the invention, inone aspect, comprises an improved machine for operating I described. In the particular embodiment of 5 the inventionherein illustrated,"themachine is. constructed and arranged to provide an in sole with three positioning, holes in predetermined, spaced relation to thecontourjof I the insole and adapted tobe used in carrying outthe method claimed in Letters PatentNo. 1,674,060hereinbefore referred to but, in some aspects, the invention is not limited to such embodiment and use.

The invention will now be described indethe treadle mechanism not illustrated);

may be of any known-or suitable construction;

The other arms24 'of'the bell cranks are connected by a tensionspring 26 which tends to'move'the free e'nds of thegages 16 toward each other 1 but their movement of approach is limited by and, more specifically, a machine by the use'of the engagement of an adjustable screw stop 28 w th a lug 30 formed as anextension of one ofthe bell cranks 20;? Another pair ofside gages336-are likewise-provided with studs 38 pivoted in the-solefsupport and connected toof approach stop'aa.

Because the gages are geared together, thecontacting surfaces of the two gages ofeach pairare always at equal distances from this centeriline, aswill V be developed hereinaftenf g The sole support l0flisisecur-ed firmly in predeterminedposition'to the machine frame which, as -illustrated, inoludesan over- ,7

hanging arm provided with a vertical bearing 52. inflwhich mounted a1 vertically erally and angularlg relative to the punches. I i

3. In a machine r punching in an insole a plurality of positioning holes in predetermined relation to the insole contour, the combination of a sole support, a power shaft, a plunge'r,-actuating connections between said shaft and said plunger, a punch holder and a yielding stripper carried by the plunger, 1 three punches mounted on the holder and so located as to form positioning holes in the Y insole, one near the toe end thereof and two rearwardly therefrom and near the sole coni ,tour, means for maintalnlng said plunger,

holder and punches in predetermined angular relation to each other and to the sole support, and yieldingly pressed gaging devices for contacting with the curvilinear contour of the toe portion of the insole at'least at four separatedpoints and thereby locating the insole on the support in predetermined position relatively to the punches. 5 V In testimony whereof I have signed my name to this specification.
