NUTT, OF IBEVERL Y, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- OF PATERSON, NEW JERSEY, A CORPORATION OF NEW IIETHOD or COVERING HEELS Application filed January 24, 1929. s m No. 334,716.

This invention relates to improvements in methods of covering heels. The invention is herein illustrated in its application to the covering of a Cuban heel with a one-piece cover the ends of which meet at the middle of the heel breast, although the invention is by no means limited to the covering of heels of that type or to the covering of heels with a single "piece of covering material.

It is a common practice to cover the rear, side and breast surfaces of a Cuban heel with a one-piece cover the opposite end portions of which are overlapped at the middle of the breast face of the heel. This practice results in the formation of an objectionable bulge or ridge in the covered breast face where the meeting end portions of the coveroverlap, a condition which defracts from the appearance of the finished ieel.

One object of the resent invention is to facilitate the formation of a smooth, flush joint between meeting portions of a heel covering.

\Vith this object in view, the invention,

in one aspect, provides an improved method of covering heels which comprises overla ping two portions of a heel covering upon a lneel surface to be covered thereby, and cutting diagonally through both cover portions while said portions remain overlapped to form on said cover portions beveled edge faces transversely disposed at the same inclinations to the adjacent portion of the heel cover surface and adapted to be neatly fitted together so as to form a flush vjoint. Preferably and as illustrated, the trimming is effected by a single progressive cutting operation, for exam le, 'bya single stroke of a knife, the kni e being drawn across the overlapped cover portions so as to form simultaneousl two trimmed edge faces which lie int e same plane. As illustrated the trimming cut extends longitudinally ,in a. direction heightwise of the heel and 1t is inclined in a direction widthwise of the heel 1 Thus skived or beveled edges are produced which. are disposed relatively to one another so thatthe edge faces will overff the cover have been trimmed lap when the cover portions are brou ht together without causing any bulge or ri go to be produced at the joint. Moreover, as

illustrated, the direction of transverse inclination of the trimming cut is inwardly (i. e., toward the heelbreast) and away from the edge of the outermost cover portion, inasmuch as this construction enables the trimmed edges subsequentl tobe brought together without the necessity of stretching either portion of the cover thereby avoiding any tendency ofthe joined cover portions later'to become separated and the joint to become opened up because of shrinkage of the cover material. After the end portions as above e'scribed, the waste material produced by the trimming operation is removed and the trimmed edges are coated with adhesive, preferably anon-elastic adhesive such as celluloid cement, and pressed firmly together so as to form the desired smooth, flush joint The invention will now be more particularlydescribed by reference to the accompanying drawings and thereafter defined 'n the claims.

Inv the drawings,

Fig. 2 is an enlarged of Fig. l;

Fig. 3 is. an elevational viewsimilar to Fig. 1 but illustrating a further step in the a fragmentary sectional view on scale taken along the line'lI-JI trimming of the meeting portions of the cover;

80 heel being positione'dwith its breast face 2 I I D a one-piece cover C has been applied in the usualway, the cover extending around and entirely covering the rear, side and breast surfaces of the heel and being held in'place by suitable adhesive such as rubber cement or other elastic and slow drying adhesive. The'heel H may be supported during the heel covering operation, as herein shown, by means of clamping jaws l0 and 12 arranged to engage respeo'ively the seat face 3 and the top lift-engaging face t of the heel. The cover C is shown in Figs.- 1 and 2 as it appears immediately after it has been'wi-apped around the heel, the lateral margins of the cover projecting beyond the seat and top lift-engaging faces 8 and t, respectively, imposition to be subsequently laid against these faces, and the opposite end portions of the cover being overlapped at the middle of the heel breast and temporarily held firmly together by means of the adhesive initially applied to the cover.

In order -to provide for the formation of aflush joint between the meeting end portio'nspf the cover. C, these cover portions are trimmed, asherein illustrated, in such a Way as to-cause the trimmed edge faces to lie in thesame plane and to be similarly disposed angularly with respect to the adjacent portions of the heel breast surface. To this end, a trimmin tool, such for example as the knife 14 (Figs. 1 and 2), is drawn across the heel cover after being positioned substantially'in the longitudinal and transverse angular relation to the heel shown in I Figs. 1 and 2, with the cutting edge of the .knife extending in a direction hei htwise of the heel breast substantially over t 1e middle of the overlappin portions of the cover. Preferably the knife is first presented to the heel with its cutting edge engaging the cover in a location indicated by the dotted line a: in Fig. l the more accurately to gage the location of the trimming cut. Thereafter the knife may be tilted more or less to bring .it into the longitudinally inclined position shown in Fig. 1 so that as the knife is drawn across the cover it will act simultaneously upon both the outer and inner overlapping cover portions,,cutting through them to the breast surface of the heel to form the trimming cut indicated at'y in Fig. 3. Thus,

as the knife is moved along the heel breast it trims the opposite end portions of the a cover from the top to the bottom of the heel breast in a singleprogressive trimming operation. As cshown,-the trimming knife 14 is also inclined transversely (with respect to its direction of movement) as shown in Figs. 1 and 2, so that the trimming cut will be inclined transversely in a direction widthwise of the heel breast. As a result of this transverse. angular relation of the knife blade relatively to the heel. breast, the

trimmed edges 'of the cover are skived 0r beveled, as illustrated in Fig. 2, and as shown zit-16 and 18 in Fig. 4. Moreover,

the beveled edges of the inner and outer cover portions will be relatively disposed so that the trimmed edge of the outer end portion of the cover will extend in the same angular relation to the breast surface of the heel as the trimmed edge of the'inner end portion of the cover. Thus when the two beveled edges are brought togetherthe fit one against the other. lso, ass own, the direction of transverse inclination of the trimming knife is inwardly (i. e., toward the heel breast) and away from the edge of the outer overlapping end portion of the will cover, thereby causing the beveled edges to Y be so located transversely relatively to each other as to avoid any necessity for stretching either co. er portion in order to fit together the trimmed edge, as will be hereinafter mor; fully explained.

In order to extend the trimming cut through the unsupported margins of the cover which extend beyond the seat and top lift-en aging faces of the heel, the knife 14, after being drawn across the heel breastas desc ibed, may then be drawn successively across the projecting cover margins in such a way as to flatten them'a ainst the seat and top lift-engaging faces of the heel,

and thereafter to out through them to the surface of the heel, th-iscompletely severing from the heel cover the material partially separated therefrom by the cut initially made across the heel breast. To facilitate the laying of the cover margins against the seat and top lift-engaging faces of the heel without danger of overlapping the adjacent end portions of the cover, it

may be desirable to continue the trimming cut through the projecting cover margins by means of scissors. This operation is shown in Fig. 3 as being accomplished by means of scissors 20 arranged to cut at a substantial angle to the cut 1 made by the knife 14 so as to form two oppositely inclined cuts a in each overlap ing end portion of the cover at opposite en s of the bevel cut 1 The scissors ma be readilymanipulated to vary the angle of cut as may be desired to provide adequate clearance for the projectin lateral margins of the cover as they are Folded back against the respective end surfaces of the heel.

After the trimming cut 1 has been extended from edge to edge of each of the.

overlapping portions of the cover, as by means of the inclined cuts 2, so as to completely to sever from the cover the waste pieces indicated at w, w in Fig; 2, these waste pieces are removed, it being necessary to raise somewhat the outer end portionof the cover before being able to remove the loo ios

waste piece end portion of the cover is rendered practicable by, the employment of a .nomelastio While the outer end smoothly against the Such manipulation of the cover portion a;

not project beyond on the contrary, will exactly register with solidatin v the heel the cover portion a s slow-drying adhesive such as rubber cement, inasmuch-"as the elastic adhesion thus produced between'the end portions of the cover may be readily broken when it is desired to remove the waste trimmed from the inner end portion of the cover. Thereafter, the adhesion may be readily re-established by merely pressin the trimmed end portion of the cover bac against the heel surface.

ortion of the cover remains in raised position thebevelededges 16 and 18 are coated with non elastic adhesive such as celluloid cement, bymeans such as a brush 22, as shown in Fig; 4. Thereafter the raised portion of the cover (indicated at a in Fig. 4) is pressed backwardly against" the heel breast and the beveled edge 16 is pressed firmly against the beveled edge 18. The adhesive originally applied to the cover and to-the heel will then cause the temporarily raised portion of the cover to adhere to the heel breast while the adhesive applied to the beveled edges 16 and 18 will insure that the beveled edges 16 and 18 will be securely fastened together. Because of the fact that the end portion a of the cover (on which the beveled edge 16 is formed) originally overlapped theopposite end portion of the cover, the" portion a, will be slightly longer (measured in a direction widthwise of the heel breast) than,required .to cover that portion of the breast which still remains to be covered. Consequently, in

order to insure that the beveled edge 16 will the beveled edge 18but,

the edge 18, the cover portion a may be manipulated while being-laid, as by'me'ans of wipin strokes in the direction of the arrow 6 in ig. 4',so as to efiect the desired accurate registration of the beveled edge faces 16 and 18 and to press the cover tightly and heel breast surface.

will result in somewhat compressing orconthe'cover material widthwise of reast, thereby smoothing out'the cover and removing any fullness which'may be present therein. This action makes allowance for subsequent shrinkage of the cover such as might result in opening up-the 'oint between the meeting edges 16 and 18. t is to. be noted that if the beveled trimming cut is made so that its transverse inclination is inwardly aw'ay'from the edge of 'the'outennost of the overlap ing and ortions of'thecoven as hereinbe' ore descri ed,:

it will not be necessary in any 7 case to stretch theend ortion of the covergwhich is finally to bela d in lace, sothat even if- I ould not be manipulated for the purpose of compressing it to the joint,

' beveled edge widthwise of the heel breast there will be no inherent tendency for the portion a of the over to pull'away from the other end ortionthereof. It is desirable that the a heisive employed for coating the beveled edges 16 and 18 will be of non-elastic character which is unaffected by moisture or varying atmospheric conditions, and which conse "quently will hold the edges permanently and ri 'dly in place.

hen a.-hee1' cover has been applied as above described, njotonly will the presence of an objectionablebulgeor ridge at the meeting ends of the coverbe avoided, but, as shown at 22 in Figs. 5' and 6, a smooth flush joint willbe portions and one which ermanently secures the end portions toget er and presents a neat and attractive appearance. A joint of this character is articularly well, adapted for securing itoget er'and celluloid covers. In the case of celluloid covers it is practicable, by buflihg or polishing the surface of the cover adjacent entirely to obscure the joint, thus giving cover.
