This invention relatesto improvements in ma- ,chine I9 ap l in cemen or Other adhesive,

to t he marginal regionsof articles havingcurved edges. More particularlyit provides improved vrneq a lsm oo applyin c en to the marginal region of o ne side of shoe soleelements, whereby a marg na r ion o predet mi W dt ma be coated with cement more effectively, economically and quickly thanhas been possible with the prior cementingmachines of whioh the applicant is aware.

It is among theobjects of the invention toprois ammbt .meq eni n a i means for engagingjthe m argin of an element which has a curved edge contourprovidingcontinuity of margin all around the element, said means applying cement to a marginal surface and simultaneously feeding the'element on a course to bring the total extent of the continuous margin into the action of the icement applying means, whereby a Work elementmay be initially manually introduced [into the mechanism, and then will be automatically "until a marginal region ext en'clin'gjall aroun d'the element has been coated with cement.

"Another object is to provide a cementing mechanism wherein a pair of work-feeding rotary members on angularlyfrelate'd axes coact'with spaced edge-guides 'tofee'd a workjelement On a course to bring every point on its edge progressively into contact with said edge-guides, Whereby said rotary members engage every portion of the'margin of the element progressively throughout the extentbf said m'argin, an d'one of said rotary members applying cement to said margin simultaneously with theieed of the element.

As illustratedflb animating; ageiierally rectangular top 12 which supported g nerally in a horiqnt l nfib llh i 5 31 H "Ageai housing I6 is mounted on one side of any suitable manner, as by i8."-j One end" portion of a extends tliroiigh housing [6, with it alls of thehousing, and a level by gravity flow through conduit 42 from a suitable supply container which conveniently may be an inverted bottle 44. Conduit 42 is connected to a nipple 48 which opens through the bottom of chamber 48, and the lower portion of wheel 38 is immersed in the cement in chamber 48, so that cement is carried upward on the periphery of wheel 38 as it rotates, the periphery of the wheel, preferably, being formed with the multiple applicating surfaces as indicated at 39 in Fig.5.

Vertically above and parallel with power shaft 28, a shorter shaft 48 has one end portion extending through housing I8 and journalled' in opposite side walls thereof. 'A spur gear 58 is fixed on shaft 48 within the housing I6, and meshes with a similar spur gear 52 on power shaft 28, so that shaft 48 rotates with shaft 28 but in opposite direction.

According to the invention, the wheel 38 on power shaft 28 is adapted for coaction with an angularly relatedwheel 54 for engaging and feeding work between the peripheries of the wheels, the wheel 38 simultaneously applying cement from its periphery to the margin of the under surface of the Work, and the'wheel 54, because of its angular setting, being adapted to urge the work relatively strongly in lateral direction simultaneously with the forward advance of the work between the wheels. Also, to accommodate variations in thickness of the work, the angularly set wheel 54 is mounted for operative yielding as may be required. I v

To these ends, whee1 54 is fixed on a shaft 58 which is angularly disposed, in a horizontal plane,

with respect to powershaft 28, as best seen in Fig.2. Shaft 56 is mounted in suitable bearings 58 on a, pivoted frame 68 whose pivot shaft 62 may be supported in a bracket'64 secured to the top]? of base I8, t he frame having spaced arms 88, 88" engaging opposite end portions of shaft 62. A generally vertically disposed screw 88 is adjustablymounted inframe 68,'with its lower end resting on the top I2 of base I8 'as best seen in Fig. 7. A wing nut 68 is fixed on the upper end of the screw, by which the screw may be rotatecl to adjust the frame 68 about its pivot shaft 82, thereby to vary thespace between the wheels 38 and 54, a locking member 69 being provided for maintaining the screw in any adjusted setting. I

The weight of the frame tends to maintain the lower end of screw 66 in. engagement with the top of base I8, but theframe can move in direction away from the base ifany work or portion of work has thickness greater than the space as provided between wheels 38, 54 by the adjusting screw 86. Acounter-balancingspring l8 acts in opposition to the considerable weight of frame 68, to facilitate yielding of the frame in response to varying thicknesses of work.

I The angularly disposed shaft 56 has a universal-connection at 12 to a relatively short shaft '54 which is mounted in bearing I6 of frame 88, in parallelism withpower shaft 28and driven shaft 48. Shaft 14 has sprocket and chain drive connection at 18 to another relatively short and parallel shaft 88 which is mounted in bearing 82 in frame 88, generally in alignment with shaft 48 to which it is slidably coupled as. indicated generally at 84-. Hence, shaft 48 drives shaft 88 which in turn drives shaft 14 and the universally connected angularly disposed shaft 56.

, The coupling at 84 is such that adjustments and movements of frame 88 which carries shaft 88 do not interfere with the driving connection between shafts 48 and 88. This is made possible by the three-part coupling mechanism illustrated, in which part 88 is fixed on shaft 48 and part 88 is fixed on shaft 88. Coupling part 88 has the diametrically disposed rib 81 on its face which is toward coupling part 88, and part 88 has a similar diametrically disposed rib 89 on its face which is toward part 86. Between the parts 86, 88 is the third coupling part 98 which has its opposite faces diametrically grooved at 9|, 9|" for reception of the ribs 87, 89 of parts 86, 88 respectively, the grooves 9|, 9I" being in right angular relation as indicated in Fig. 7. With this coupling construction, it will be apparent that coupling part 88 may move along the groove 9I' of part 88 a considerable amount in either direction without reducing the effectiveness of the drive connection between shaft 48 and shaft 88. Or both of the coupling parts 88, 98 may move together in either direction along rib 87 of part 88 without affecting the drive connection.

It is a feature of the invention that work, such as a shoe sole element 92 (Figs. 8 and 9), when fed between the wheels 38, 54, is engaged at its margin, with wheel 38 applying cement or other adhesive to the under side of the engaged margin, and with the two wheels coacting to feed the work edge against a pair of guide rolls 94, 88. The work rests on a suitable work support 98 as it is manually moved into wheel engagement. In Fig. 8, the sole element 92 is shown in full lines shortly after having been inserted between the wheels, and the successive broken-line representations of the sole element show various positions of said element as it moves generally counter-clockwise to receive a coating of cement all around its under margin. The general band-nature of the coating is indicated at 88 in Fig. 9.

The guide rolls 94, 98 are arranged in spaced relation in positions to engage the edge of the work as the work advances between the wheels, with the wheel 54 strongly urging the edge of the work against both rolls, so that the latter guide the work in such manner that the applicator wheel 38 coats the under margin all around the sole element.

Another feature is that the main body of the work, inward from the engaged margin, is effectively maintained generally in the plane of the engaged margin by a generally dish-shaped roll I82 which automatically adjusts itself to accommodate varying thicknesses of the work at the region of its engagement by roll I82. As best seen in Fig.6, the dished. roll I82 has a tapering axial hole I 84 through which .the endportion of shaft 58 loosely passes, with a washeiQI 88 secured against its extreme end. Acoil spring I88 engages between the washer and the dished roll Ingresilientl biasing roll I82 against; the outer face of feed wheel 54. The surface oflroll I82 which is thus urged against wheel 54 preferably is convex toward the wheel as at H8. The peripheral wall of the dished rollf I82 is adapted to engage the main body of the work whose margin is gripped between the feed wheels 38, 54, and the roll I82 readily can adjust itself on shaft 58to accommodate variations in the thickness of the work, yet always maintains' the body' of 1 the, work generally in t l e of it gr p d m r i ti' As the d S roll I82 is loose on shaft 56,1 and' not driven thereby, it can follow along bribe work,

of thewheel carries more'or less: cement upward on its periphery for application .to the undenmarginal surface ofthe work. The amount of cement thus carried up may :ber'egulatedby adjusting the stripper plate 1 12 toward or from the wheel by means ofthe knurle'dlfingerlnut Ill-4.

' The stripper plate .l l2iis shown'cut out at .113 for fitting loosely around :the peripheral portion of the wheel 38, the plate 112 being connected at M6 to a carrier plate llli whicli is sl'idably mounted between-the part of cement cont'a'iner -60 and the work-supporting plate -98, which is removed in Fig. 4. Carrier'plate =li 8 has a slot It!) therein through which a screw 1-20 extends for securing support platailain place, along with the smalll'erscrews t22i outward from the carrier'p late. As shown -in-Fig'. 3, the screw I-Zfl extends-loosely through the part 41 and has the fingernut i2 1 onits end for securing "the screw and plate 98 in place.

Adjustment'of the carrier plate H-B may be elifected by the knurled nut H4 which has'rigid with it a flange H5 engaging'in a'transverse slot I26 in the carrier plate. Nut 1 I' l-rs" threaded on a screw $28, and when the nut is'turned on screw H23 the fiange merges the 'carrier plate toward 'or from the wheel-3'8 to reduce or enlarge the'space betweeiistripper ;pl ate"ll2 and the wheel.

At the opposite side of wheel 38, a fixed member Hill is set close against the periphery of the wheel to act as ada'm ffor accumulating cement adj acent to the region of ceme iit'application'ftc the work. It wil1 be apparentfrom theioregoing descri tion that I have provided,efiectivemechanismfior applying cement uniformly all along the margin of asole, element orthe like whichauto natically advances to bring the entire extent of the margin,

all around the sole element, intolth'e actionof the tion away from wheel 38 to accommodate varying thicknesses of work and to facilitate removal of the work after a cementing operation thereon has been completed.
