' 60mi s;-f(ol..12;;r46)f This invention relates t'o the manu facture of welting,{ particularly of beaded welting used as mockwelts' and the like; Y I I I p v I Calhing welt comprises a body flange'for receivcalking weltin Goodyearshoes, nailed shoes,

'ing the stitchingfand an adjoining edge bead the 'combinedvvidth of which is $6 inch in the most desirablefcommercial size. 9 In the manufeature of types-heretofore commercially avail-j able Ya strip i at" inch wide has been required to produce a inch *cal k ingwelt. Saving tof stock is ofgreatirnportarrce and any method by which standard calking welt can be made starting with a narrower stripof'leather is eagerly sought for.

The object of this invention"isftofprovidea method of making ca1k in'g welt of standard width from a strip of leatheronly slightly wider; and to the accomplishment'thereof the steps for practis ing the method will be described inldetail in con nection with accompanying drawingand the scope I of the inventionwill beset forth in the appended claims. I

in the drawing. all the fl'guresb'eingjin perspective,'

Figurel shows stripfof grain faced leather (Figs. 2 land 3 show; respectively, the first preparatory cutting of" the strip arid't he resultf thereof.;-

Figs. 4', Sand 6'show the progressive forming up steps to produce a calking welt from the cutblank of Fig. 3, and V Fig. 7 shows the finished welt, molded and trimmed.

In practising the new method, as illustratedby the accompanying drawing, for the production of inch calking welt a strip I0 only inchwide need be used. This may be leather having a natural grain face or it may be a split having had grain applied to one face as by cementing thereto a grain ribbon obtainedfrom finishing processes in the manufacture of other kinds of welting, or in other ways. In the following description and claims grain faced is inclusive of either a natural or an applied grain. The present method depends on the formation of aU-shaped blank from the grain faced strip before performing the forming upsteps. Accordingly a segment I2 is out from between the two faces of the strip Ill leaving a blank (Fig. 3) having a grain faced wing l4 and a flesh wing it connected at oneedge by an uncut portion l8 of'the original stock, this portion being the flesh remaining after removing the segment l2. At the time the segment I2 is removed the flesh cornerof the stock which becomes the wing connector 8 maybe beveled as wing I6.-

at" 19- llQ facilitate forming upl as presently ex- .plained; It willbe observedfthatthe mirror re'- moving the segment 2 provides a chainfered'inner edge; Thisleaves an obliique'fac'e 2E on the'connectorsto ck; 18 which makes the flesh win'gwider than-the grain'faced wingth'e purpose of which willfbe' plain when the forming up of the blank isf'des cribed; Those skilled in the artwill recognize tliatithesegment 12f, although/composed of splitleather; .is' of commercial value and; is not a'calkingwelt asillustrated by Figs. 4 to 6; ffhe. wingsfldf and' lfij are" opened about "the joinder' of th'e flesh wing 16' with the connector stock'flB' as a hinge, thisbeing the point where there: is the 'least'connector stock to"resist' bending, until the] grainat the connected end, atileast, of the'winggl 4 i stands at substantialri htfangles-to' the. flesh strip l'llinto general alignment withfthe bottom of the 'flesh'wingf Hi1 thus forming an extension thereof. It alsoturns the g 'connector stock l8 to aposition wherein its bevel 2 dslopes upward and outward from the ifs'aid] fleshwing' l6. "j "cement maybe'applied tojthe" inner faces of {the two wings at any time, after the"wings"ha've been opened sufiicientlyto .be contacted .by acerrient roll .or' other applying devic. Any satisfactory kind of enduring cement may be used. The grain faced wing I 4 is now turned back toward the flesh wing I6, the hinge being at the upper edge of the bevel 20, and is pressed into contact with said bevel and with the cemented face of the flesh The final step is the pressing andlmolding to Y shape. In these operations thebead is rounded or otherwise shaped as desired and the pressure is suflicient to form a substantially flat bottom and to preserve the substantially, square corner at the base of the head; It is convenient, during this step, to remove the string 24 which is the excess width of the flesh wing after the forming up operationshave been performed.

An important advantage of this method of producing calking welt accrues from selecting a substantially triangular cross-section for the connector stock 18 which supplies the body stock forthe edge bead. Heretofore the stock of the bead body has been of rectangular cross-section concaved back for fitting to the shoe stock which.

it' contacts. The oblique face 20, which forms the rear face of thebead body, "eliminates cor-1 ners which must be molded down, provides an initial cross-section that approaches the final shape of the bead facilitating molding a narrow top edge, and presents a rear wall that may readily be shaped as desired.

The operations described, when performed," produce a calking Welt having a flrm and strong body for receiving stitches,"a bead that isgrain faced throughout its surface and a fieshbottom that will lie flat and cling to the underlying material of the shoe in which the welting is used.

Variations in the described steps used in the method of manufacture of the calking welt may be made without departing from the principles and scope of the invention as defined by thefollowingclaims. 3

Attention; is called to applicants co-pendin-g application for calk sole welting and the like,

Serial No. 533,993, filed April 30, l931, in which will be found generic claims covering the calk welting herein disclosed and its method of manufacture. The claims of this application are 01 confined to the novelmethod of making one piece welting as disclosed herein and such equivalents as, may be permitted by the prior art.

The nature and scope of thein'vention-havw ing been indicated and the preferred method of 35. manufacture having been described, what is claimed as new, is:

1. The method of making calking welt and the like which comprises removing a segment centrally from a strip of grain faced leather form- 40 ing a U-shaped blank having a grainffaced wing and a flesh wing connected atone edge by an uncut portion of the original stock, opening said wings about the line of joinder of the flesh wing I torsaid connector stock, cementing their inner faces, turning the grain faced wing back upon said connector stock and upon saidflesh 1 wing firming an edge bead, and ressing and om; ing to shape. V V i ing to claim 1 in which the said segment has a ;chamfered inner edge leaving an oblique face on said connector stock between the two wings.

3. The method of making calking welt according to claim 1 inwhich the said segment has a chamfered inner edge leaving an oblique face on said connector stock between the two wings, said face, when said wings are opened, sloping upwardly and outwardly from said flesh wing.

4. The method of making calking welt and the like which comprises removing a segment having an inner chamfered edge centrally from a strip of grain face leather forming a U-shaped blank havinga grain faced wing, a flesh wing wider than the grain faced wing and connector stock at oneedge that is the flesh of the original strip, opening said blank by turning substantially 90-on the lineof joinder of said flesh wing and the connector stock, cementing said wings, then "folding said grain faced wing down upon the beveled face of said connector stock and into contact with said flesh wing forming a grain faced beaded edge,,and molding the welting to shape.

5. Themethod of making calking welt and the like which comprises making parallel slits in one edge and, partway across a strip of grain faced leather and removing the flesh stock between said slits leaving two wings connected at one edge by the remaining flesh stock, cementing the inner'faces ofsaid wings, and then rolling said connector stock'outward and wrapping a portion ofone of said wings about said connector stock I to make abeadand securing the remainder of saidwing to thejother wing to make a body adjoining said bead.

6. The method of making calking welt and the like which comprises removing a segment centrally from aIstrip of grain face-d leather form-- ing a U-shaped blank having a grain faced wing and a flesh wing connected at one edge by an uncut portion of the original stock, opening and cementing the inner faces of said wings, rolling said connector stock outward to lie at the end of said flesh, wing and to turn its grain covered face at substantialv right angles to said flesh wing, laying the lgrainvfaced wing against said connector stock and the flesh wing, and pressing and molding to shape.
