lifts, one may wishfto apply, asillustra'ted in 9, a coating S of the-adhesive; this being inter rupted near its outer edge by an uncoated band s corresponding in curvature to :the periphery of the article. "Ilnsarrangement causes the assembled heel-portiohsto beheld firmly together at the periphery',-so there will be to the purchaser of such heels no appearance ofchecking or tend-' ency to separation between the layers. "Yet.

when the heel is trimmed-afterattachment to a depth entering the uncoated band-$ n'o-adhesive will appear at the surface to impair the finish,

and there'will be no evidence of separation be tween the lift and rand, on accou'ntof the compressing operation to which the heeljhas been subjected. This effectisobtairied by providing 1 in the applyingsurface of the roll 24 a groove I35, from which the adhesive is removed before I the work is reached by the side of the roll rising To dispose of-the excess o'fithe adhesivesubstance which is brought up by theiroll from the trough, and to ,clean-"thegroove I35, a scraper is that it will lay no coating uponithe work' From the plate, at each side of the edge I38, isa curved projection-I42 (Figsn iand 7) lying close to the end of the roll. These projections prevent the adhesive from working along theends' of the roll to the shafti The curvature oftheprdjctions causes the adhesive to bedefiected outwardly, so it falls clear of the ends of the roll-. The plate I36 'adjustably secured by aslot-and-screw connectionJM to the fiattenedsu'rfaceof a carrier rod I46 extending through a horizontal bore in, a pivoted holder or. support I48, beingnorma'lly' fixed against movement in the bore by a set-screw I50. 'Ihis'permits adjustment of the scraper I36. with respect to the support I48. in-a plurality of directions. A pivotal mounting of'the holder is furnished by ahorizontal spindle I52 supported inlugs I54, I54' (Fig. 1) upon the arm 34, this spindle passingthrough depending portions of the holder, and of a horizontal extension I56 thereof." A screw I58 extends through an opening in an upwardly projecting lug of the'holder I48, andis threaded into the'arm 34. A spring I60, interposed between the arm 1 and holder-lug, urges said lug against the head of-the screw, the adjustment of the latter determining the approach of i the edge I38 of the 'scraper to the roll '24, and therefore the extent to which the'adhesive is removed from the applyingsurface; A stop-screw I62 (Fig. 7), threaded through. the holder and contacting with the arm; fixes the minimum spacing between the roll and scraper. The alteration' in the position of the mans and of the scraper upon "said rod provides initial adjustments of the scrapertransversely' of and .toward and from the'roll. If the application-of an uninterrupted band of adhesive isdesired, asappears in Fig. 10, the applying roll will have a continuous pocketed peripheral surface, and the edge I38 of the scraper-plate I36 will'be unbroken, thisarrangement being illustrated in Fig. 8.

Considering now'theengagerhent of the rolls -22 and 24 with the i work, the first -mentionediroll. is shownas having-about itsperipherm'lying along I elements of the conical 'surfaceQaseries of elm-.1

gated teeth I64 (Figs. 2 an-d -3) which effectively engage the work to feed it forward. rThe'normal' angle between'the adjacent contact-peripheries of the rolls, or. at'thebite, is substantially. equal. to that 'betweenthe opposite faces ofthe article upon which they are to operate, as a beveled rand.

For variations in the thickness of the work, considered from pointto point longitudinally, theapg itsspring 40.

(Fig. 3), within whichlis located the lower extremity of the shaft- 20.} Theshaft-end H2 is spherical, with-a reduced neck between it andthe: body of the shaft, to provide clearance'forthe gyration or tilting of the roll. "Arranged to turn in a transverse bore inutheshaft-portion. I72 is Ia cylindrical pin. Ifl4,.whichis capable of. angular movement about the cylindricallbody-portion I16. I

of a screw I"I8. This, screw is threaded into the roll 22 at one side,.and,'after passing through the' of the screw; Since thereis acapacityfo-r-tilting of the roll about theaxis of the screw I18 and about the axis ofthepin I14,'said roll is mounted for universal. movementiandzcan be caused to maintain full contact. with work of Qdifferent transverse inclinations as the shaft 20 rotates. 'To'yieldably maintain theroll'22 in a' definite position generally corresponding "to the "normal or average bevel 0f. the work, said roll has at its upper end, at. right angles to the axis; a finished surface I82 (Fig. 11). surrounding an annular flange or neck I84 uponthe-g roll. On this s urface. I82, at opposite. sides of the flange, bears the forked end of-a leaf-aspring I88 (Fig.1) ad'-' justably secured by a 'slot -and-screwiconnection I88 to-a curved'portion I90. of a bracket I92.- The center of curvatureof the: bracket-portion I90" preferably lies approximately at the center of the joint J. The bracket isfixed to the frame I0-for vertical adjustment by. slot-and-screw connections 'I94.- The roll 22 will be'heldupon its universal mounting by the pressure of the spring I86 at a predetermined normal. position, which def. pends upon the angle of the spring, yetit can.
