the welt hasbeen attachedto, the shoe-is.

, likely to mutilate theedge of thewelt; .Molej over, it is' diflicnlt to position the welt-.acc uw rately enough, if the operation isperformed in. this manner, to cause the welt to contact at all points as it should with the shoeupper.

To obviate these and other difficulties wehave invented the shoe and 'methodpf Letters Patent of the United States No. 1,687,267, granted October 9,1928. In the manufactnre of shoes in acordance with the method of said Letters Patent the welting is fastened to the 1 overlasted portion of the shoeupp the outsole is attached to the shoe. It is an object-of the pres'enti provide a fastening inserting machine particularly adapted to be used as an aid in carrying out the above method. "As illustrated herein, the inventionis embodied in :afitaple inserting machine, which may be of the well. known type disclosed inLetters Patent-of the United States No. 1,016,930, granted February13, 1912, on an application ofWilliam H;

" With the" aboveand other objects and ,tures in'view the invention will now be; described as illustrated in the accompanying drawings andpointed out in the claims.

"After this the 1 inside-former 30 iswithdrawn by mechanism provided for that "purpose and the driver 14 V V descends forcing' the staple {through 3 the s stapleda .,WeltT38 guidedtofasteninglinsent V illustrated in Fig. 3, to make this feeding ing the shoe and the welt past the nozzle of the machine, as indicated in Fig. 2. Preferably the feed roll 46, which engages the surface of the welt oppositethe overlasted portion of the shoe upper, is roughened, as

action more effective, while the surface of thefeed roll/l8 is smooth to avoid injuring the shoe upper. Journaled in the bracket 42 is a horizontal shaft which carries at its forward end the feed roll 46. A bevel gear 52 is secured to the feed roll 46 and meshes with a bevel gear 54 secured to the feed'roll 48 so that rotation of the shaft 50 serves positively to drive both feed rolls. The shaft 50 is power-operated by connections which will now be described. 7

Fast upon the main shaft 56 of the machine (Fig. 1) is a cam member provided with a'cam track 58 in-which is locateda cam roll 60 carried by a lever 62 fulcrumed at 64. Pivoted at 66 to the outer end of the lever is a link 68 the other end of which is attached to the upper end of a rack bar 70 mounted for approximately vertical sliding movement in a slideway 72 carried by the bracket 42. Loose upon the end of the shaft 50 is a pinion 7 4 meshing with the rack bar 70 and, accordingly, rocked first one way and then the otheras the lever 62 is oscillated by the rotation-of the cam shaft 56.

Secured'to the pinion 74 is an arm 76 to which is pivoted a spring held pawl 78 cooperating with a ratchet 80 fast on the shaft 50. Thus it will be seen that the shaft 50 is moved intermittently or step-by-stepin a clockwise direction, as viewed in the various figures of the drawings, thus rotating the feed roll 46 in the same manner and, by reason of the intermeshing relation of the bevel gears 52 and 54, rotating the feed roll 48 synchronously with the feed roll 46 in a direction to feed the shoe to the left, asviewed in Fig. 2.

In-the operation of the machine the end of the welting 38 is passed beneath the nozzle 10 of the machine, and the shoe is held by the operator with the upper and the edge of the welt in engagement with the periphery of the feed roll 48 andinposition to press 7 1 the welt 38 against the periphery of the feed roll 46. Then the machine is started and a staple is formed and inserted through the throat opening 12 of the nozzle 10, securing the end of the welt 38 to the overlastedportion of the shoe upper. The staple, as'illustrated, passes through the insole 81 of the .to rest and another staple isinserted. This operation is repeated progressively along the side of the shoe, around the toe and back along the other side. The welt may be attached, as preferred, either merely from the heel breast line to the toe of the shoe and back to" the heel breast line or about the complete periphery of the shoe including the heel seat.
