a citizen of the U ted St tes, residing at Blockton', in the c unty 0 Plymouth and State of Massachusetts, h 've invented 'certain new and usefiil Imp ovements in Machines for Qperatin on Welts; and I do hereby declare the ollowin clear, and exact description 0% the invention, such as will e'nab'le others skilled in the art to which it appertains to make and use the same.

The present invention relates to a ma- -Be it known that Jorrgi B. HAnAwAY,

' chine for operating on welts.

In the manufactnreof wlted shoes, the welt after bein'g-attached'to the shoe'is 'subjected-to a beating out operation in order to cause it to lieflat in substantially the plane of the insole. To facilitate the beat: mg out operation the welt is usually slitted or slashed at .certain points and particularly at the toe portion of the shoe. The

slitting or slashing-of the welt has usuall beeupcrformed by means of a hand kni e after the welt is attached to the shoe and before the shoe is presented to the welt beat- 1 ing machine.

.provide a simple an The object of the resent invention is to operating upon welts by which aseries of slits .can be quickly formed in a'welt in a certain and satisfactory manner and the Welt thereby prepared for the operation thereon of the welt beating hammer or other tool of a welt beating-machine.

\V'th this object in-view, the present invention consists in the devices, combinations. and arrangements "of parts hereinafter described and claimed, the advantages of which will beobvi-ous to those skilled in the art from'the followin description.

' The invention is intende primarily as an improvement in welt beating machines, the .means for slitting the welt being associated with means for beating out the welt so that the welt is slitted and beaten out at one operation. Certain features of the invention are, however; appllcable to a machine for operating upon a welt after attachment to the shoe which does not embody means for beating out the welt. Certain features of the invention are also applicable to a machine l'or operating upon a welt or strip of welt material before beingattached to a shoe to 'prepa wthe'welt for easy applicato be a full,

The illustrated embodiment of my invention consists, in general, of means for supporting the welt, means for beating out and feeding the Welt and means for slitting the welt, together with means fol-throwing the welt slitting meansinto and out of operation during the continued operation of the beatingout and feeding means.

Referring to the drawing the means tor supporting the welt consists'of a rotatable work support 1, constructed to enter the crease between the upper .and welt and to support the welt for operation thereon by the beating out and feeding means and welt slit-ting meansit is'mounted on a stud projected'upward from the base 2, providedon its under side with a tongue and groove connection with the slotted arm 3 projected forward from the frame -l of the machine. A bolt- 5, passing through the slot in the arm 3, serves to hold the base 2 in adjusted position thereon.

The means for beating out and feeding" the welt consists of the wheel 6. shown in detail in Figs. 4 and which is splined on the,

front end of the main shaft 7 of the machine. being held in place by a nut which holds aid wheel against a shoulder near the end of the shaft. The surface of the beating out and feeding wheel. 6 is scored or roughened to enable it-to obtain an efficient on the welt for feeding the same. The op 0 crating surface of the roll 6 is normally held in such position with relation to the Iworlt suppor that when the shoe-is presented tothe'maclnne the roll beats with pressure upon the welt thereby beating out and feeding the same during the operation of the machine. The main shaft T is mounted in suitable bearings in'the swinging arm 8 pivoted at 9 between the ears 10 projected upward from the rear part of the frame 4: of the machine. The swinging arm 8 is held from lateal deflection at its front end by the ears ll projected upward from the from part of the frame of themaehine between which eats the swinging arm 8 is adapted to slide vertically. Springs 12 are employed normally to pull the swinging arm 8 downbosses projected from swinging arm 8 can be regulated whereby the pressure of the beating out and feeding wheel upon the welt may be \"flllEd: Stop collars 16 are adjustably secured to the rods 13 above the cars 14 to limit the downward motion of the swinging arm so that the knives of the welt slitting wheel shall not come in contact with the work support. A lever 17. pivoted at 18 to the frame 4 of the machine. bears with one end upon the underside of the front end of the swinging arm and to its -,OIl191 end attached a rod 19 running down to a suitable'treadle mot shownh allords means of raising the front end of the swinging arm. and thereby of raising the beating out and feeding wheel so that the work may be conveniently entered between the wheel 6 and work support- 1.

The beating out and feeding wheel 6 has two functions. one thatot beating out the welt. and the other. that of feeding the welt. and such wheel may be regarded. therefore. either as means for beating out the welt. or as means for feeding the welt. or

' both. In some of the claims I have included as an element. means for beating out thrwelt by which I intend to define as an element of su'ch claim; any suitable means for V beating out the welt witl'tout limiting such element t tl'tespccific forms illustrated in the drawings and irrespective of whether uch l eating out means has the additional In other claims I have included as an element means for feeding the welt by which I- intend to define as an element of such claims means for feeding the welt without limiting on the lower ends of i l r 7 tion 26 of the body 21. receives a fork such element to the specific form illustrated in the drawings and irrespective of whether such welt feeding means has the additional function of beating out thc welt or not.

The means for slitting the welt consists of the welt slitting wheel. indicated in a general way by the reference character :20. The

weltslitting wheel 20 consists of a body 21 provided with radial slits 22 which receive the shanks of knives The shanks of the knives are wider than the slots 22 and projectut beyond the same and are engaged on their projecting edges by a plate 24. which is provided with a series of projecting teeth which engage corresponding teeth on the projecting edges of the knives. which plate '24 is screwed onto a boss on the'body 21, whereby the knives are securely held in place and atthe same time are capable of being adjusted in and out to regulate the distance that they shall project out beyond the surface of the body 21.: The cutting edges ofthe knives lie in planes including the axis of the shaft 7 and the main portion of such cutting edges also lie in the surface of a cone whose apex is in the said axis prolonged beyond the front end of the shaft 7' so that the cuts made by the kniv s in the welt "per in depth from the outer edge of .the w it toward the inseam stitch receiving portions thereof.. The bodv 21 is slidingly mounted on the shaft T but is splined thereto so as to be held from rotation with relation thereto, and a groove 25. m the reduced porl means of which the, body :21 may be moved longitudinally of the shaft 7. In Figs. 1.

i and 12 .of the drawings the welt slitting means or wheel 20 is shown at the llllllb of its forward movement. The beating out and feeding wheel 6 is provided with a rearwardly projected rim which is slotted to receive the ends of the knives 23 which project outwardly beyond the'outer surface of the body '21 6f the wheel 20. such body 21 being smaller than the cavity in the rear side of the wheel 6 formed by the rim 25 so that the said body 21 may be received in said cavity when it is moved to its forward position as shown in the tigur'es above referred to. The sides aliord support for the projecting ends of the knives 23 when the wheel 20 occupies its forward or operative position. In order that the welt may be shtted only at those portions where it is necessary or desirable to slittne welt to enable it to be readily beaten out llat' means are provided for moving the wheel 20 into and out of operative position during the continued operation'ot the beating out and feeding wheel 6. such means con isting of the fnll' 27. above referred to, which is mounted on the forward endof a. reciproeable slide 29 mounted in d suitable bearings 30, integral with. or-seof the slots in the rifn 28' ii i and at the other end to the swinging arm 8 by means of which the lever 33 is normally held in raised position, so that when the lever 33 is depressed by the treadle connected to the rod the cam roll 31 on the side of the slide 29 willbe moved by the slot 32 forward, thereby moving the welt slitting wheel into the position. illustrated in the drawing. \Vh'en the foot is lifted from the treadle the spring 36 will pull back the slide 29 thereby withdrawing the welt slitting wheel from operative'position. The upper por ion of the slot. 32 receives the stud,38 securtdto the side of the swinging arm 8. "The slot 32 is of such a length that the end of the slot engages. the stud 38 when the lever 33 is depressed to the extent of moving the slide 29 to the limit of its'forward inc-cement and pressure then exerted u'pon the treadle connected to the rod 35,.is transpressure is exerted upon the swinging arm eyond that which is exerted by the springs 12 which operates topress the beating out and feeding wheel 6 with greater pressure welt; slitting knives are in operatiom-as during the slitting around the toe of a hoot or shoe, the pressure of the beating out and feeding wheel 6 upon the welt is increased 40 at the time when the greatest pressure is necessary for this purpose as it is well known that more beatingo'ut is required, or greater pressure is required,to beat out the portion of the welt extending around th'eftoe of a 5 bootor shoe. v I

I In some of the claims I have used the expression means for slitting the welt by which I intend to define as an element of such claims any suitable means for slitting the I weltv without limiting such element to the specific form ilhistrated in the drawings as any means for slitting the welt is within the purview of 'my invention. viewed in its broader aspects. p

The :iving means provided for driving thebeating out and feeding wheel 6 and welt slitting wheel 20.consist of the main shaft 7 which is provided upon its rear end with a gear 39 which meshes with a pinion 40 'otlinoimted upon auxiliary shaft all whichis fixedly secured to the rear part oftheframe 4. A fast pulley 4:2 is secured to the sleeve 43 formed integral with or secured to the gear' 40 andthe loose pulley-44 loosely mounted upon the shaft 41 along side of the mitted to the pin 33 whereby an additional;
