((31.12-80) ber haVing a surface which advantageously en- My invention relates to machines for applying an adhesivecoating, it being particularly'concerned with cementing the-channels of shoesoles.

7 When, in channel-cementing, the channel-bed is comparatively fiat and does not vary greatly in width, as is commonly the case -in -lliittleway Work, less difficulty is encountered in the desired application of the adhesive to the bed and to the 10 i .ne-r side of the channel-flap than, for example, when operating upon welt shoes. In shoes of the welt type, while the channel-bed. at the forepart of the sole is usually flat, this is not true at the shank, and; especially in womensjsh'oes, "where it is curved laterallyand is wider than at l the forepart. Withsuch an applying device as an extruding nozzle, which has the flap-coating and bed-coating portions in fixed relation proper delivery of the cement throughout the entire zu: length of the channel of a welt shoe maybe impossible because of the need for keeping'the nozzle outlet almost in contact with the work. The difiiculty is increased by abrupt changes in the form of the bed, asat the ball-line or juncture'of' :5 theiorepart and shank. The varying width and contour of the bed also gives trouble in obtaining .a uniform application of cement. Further, in

welt work, the channel-flap is often relatively thick, and in its turned-back position may be :m heavily wrinkled and lie close to thetread-sur- 7 :55 operation smoothly; Without cramping, andin a position convenient-for manipulation bytheyop erator; to bringthe flap free from irregularities to and hold it in its cement-receiving relation: by

At 20, the nozzle-body overnangsand rests upon the bracket and, is clamped] I thereto for ready removal by a. double-armed 55 thereon.

Flow through the passage 42 i The point of this screw is turned against an inclined edge upon the overhang 2t, and the round.- ed. ends 26 of the arms'are forced against the under side of the bracket to fix the nozzle in place The cement isdelivered to the work through two nozzle-sections '33 and 32 (Figs. 10, 11 and 12), which may be of metal or other rigid material and which respectively coat the inner face of the channel-flap and the bed of the channel.

, The flap-nozzle is made up of two plates 34 and 36, the former resting against a vertical face 38 at the end of the body I8. The outer plate 36 is held against the inner, and said inner against the body, by screws 40. Extending downwardly along the body and opening through the face 38 is a passage 42 (Fig. 9) to which cement is delivered by way of a pipe 44 rising from the may be governed bya screw 48 threaded through the body 18,. with its end extending into the passage; Through the plate 34 of the nozzlesection til is an opening 58, which registers with the passage 42 and with the upper extremity of a groove 52 in the plate 36. Opposite the lower portionof this groove is a recess 54 in the plate 34, and from the groove and recess lead grooves 56. registering with eachother and forming a passage opening through the end of the nozzlesection to coat the root of the channel and a small fraction ofthe channel bed. Along this passage, the plate 36 is cut away to furnish a,

discharge-slot 58 (Fig. 10) of 'sufiicient length -to extend for the full width of. a chanel-fiap applied to. it. The point 5"] of the section 30, entering the angle or root of the channel, furnishes agage .to position the work as the operator advances it. .To this point, the walls 59 and 6| adjacent to the discharge-slot are inclined down- 7 ,The bed-section 32 of the nozzle has an arm Eitprovided with lugs 62, 62 lying at opposite sides of a projection from a bracket 64 attached to the side of the body IBV Through the bracket projection and the arm-lugs is a pivot-pin 38, its axis approximately. intersecting the gaging end-portion 51 of the nozzle-section 30. Thus, the nozzle-section 32. may move toward and from the channel bed in a plane substantially parallel to section 30 about an axis coinciding with the point atwhich it is guided. Extending through the arm Bil is a passage 58 (Figs. 9 and 12) leading through an end-face 10. With it registers an'opening llfrom a recess 14 in an inner plate 13 of the nozzle-section 32. A second plate '18 of .this nozzle-section closes the outer side of the'recess l4,v both plates being secured to the arm bya screw 80. The inner side of the plate 18 is recessed at 82, the wall along the lower portion of this recess forming. with the lower edge ofthe plate 16, a slot 84, which will extend in a generally horizontal direction across the the point ofv the nozzle-section 32.

passage to the body-passage 42 (Fig. 9) Flow lever 22 fulcrumed upon the body and having through these passages 68 and 42 may be pro threaded through its connecting yoke a screw 24.

portioned correctly by adjustment of the screw 48 which controls the passage 42 directly and forces the balance of the cement delivered by the pump into the passage 68. The edge of the nozzle-section in which is the slot 84 is drawn yieldably down by a tension-spring 90 joining a lateral projection from one'of the lugs 62 to thenozzle-body. This allows the section to float over the bed of the channel, it rising and falling as the contour of said bed or the angle at which the operator presents the work varies. At all times, it remains in' correct applying relation.

"The edges 9! of the nozzle-section 32 at each side of the slot 84 are shown as arcuate or curved inwardly. Thiscurve preferably lies between an are which would approximate the maximum transverse curvature of the channel-bed, as at the shank of a shoe, and thechord of the arc, this corresponding to the comparatively flat bed at the forepart. This mean nozzle-contour will give a proper delivery of cement to the bed about nozzle retain it against discharge; To avoid interference with the cementwhich has been laid upon the channel bed by the slot 84, the edge 9! of the plate 78 is higher than'the corresponding edgeof .the plate 76, as are also both the similarly located edges ofthe' plates 3% and 3B of the nozzle-section 36 (Fig. 8).

Cement is introduced into the passage 42 through a flexible tube or conduit 92 extending from the pipe 44 and which may be joined to a source of cement under pressure, as a pump, indicated at 94 (Fig. 4) The: pump may be actuated through spur-gearingfifi (Fig. 5) from. a

main driving shaft 98 journaled transversely at the rear of the head and receiving power through a pulley Hi0.- IM which may be opened and closed through a shaft I06 joined to its stem and underthe control of a treadle-rod It! in a manner later tobe described. Included in these controlling connections is a'shaft section I08 having at its ends universal-joints, one .of which is readily separable. 1 Upon freeing the nozzle by releasing the v v clamp-lever 22, this separable connection and th flexibility of the tube 92 permit the operator to immerse the nozzle in a tank -I I0 containing a. solvent for the cement, 'so the nozzle may not become clogged when the machine is notin, use.

From the tank,.which is attached to one side of the head, projects achamber in to receive the hose88. of the nozzle-section 32 as the nozzle is placed in thetank, as shown in Fig. 2, with its lower extremity separated from the bottom wall. A hinged cover I I4 is provided for the tank. and,

inwardly from one edge, extends aslot H6 of suflicient width to receive the'nozzle-body and the clampinglever 22, with the nozzle-overhang 20' resting upon the outer surface of the cover. When thus positioned, the lever may be forced by the screw 24 into engagement with the inner cover-face to secure'the nozzle as it was upon the head-bracket I6. With the nozzle mounted in this manner, the cover may be swung down In the nozzle-pipe 44 is a valve ings of.the nozzle immersed in thezsolvent; A r

If there is contact] j between the finger-edge I04 and the sole-surface,

the spring I'I l will yield and thus reduce the. pressure upon the sole'to an unobjectionable minimum.

The flap-lifting and pressing movementof the finger I is preferably effected byoscillating I90 pivotedto an upstanding arm of said lever. The opposite end of the rod-is articulated .to a generally vertical lever, I92 fulerumed upon the head and having at its lower extremity a Te this spindle,'between the. carrierl-lever I68 through afcoii'ne'otingrod I roll I94 lying in acarn-track in' a. disk I96 fast 2 upon the main shaft 98 The surface I82 of ';the finger-isthereby-rapidly pressed upon and withdrawn from the work, alternatelyholding' itsmodthly against the surface 590f the nozzle over the deliveryslot 5B and freeing it to facili- Itate the feed. To position the *fin fir with respect to the nozzle for operation upon :channel 'fiaps of different thicknesses, a preliminary ad 'justment may be madeat I18. -To give a finer adjustment and one which may be used when the machine is in operation, the cam-lever I92 is fulcrurned upon an eccentric-I97 fast upon I a supporting spindle I98 rotatable in the head 1 i2. Secured to the spindle is'an arm 200 pro- "videdriwith aspring latch-pin 202, which may engage anyone-of a'series of openings in a stationary segment-204.] The turning of the spindle will-shift the lever 'I'92'jand, throughthe rod I90, alter the angle oi the carrier-lever I68 and,

.eonsequentl'y, the space'b'etween the finger-headmsurface I82 and'the,nozzle-surface 59." 'The extent of' movement of the lever I92 will remain the same but the loqusjof its movement, and

hence. the mevement of the finger" I60, will be changed.

The ieed-rolii22, is tau-at into active rem:

Projecting outwardly i'roinand arranged toturn about the spindle tilt is the horizontal arinof a hell-cranklever are, this, at its outer extremity, having. an opening through which passes the treadlerrod Hi1. Fast upon the rod near its upper endis a cellar 222, and between this andthe' bell-crankis intern-osed a compression-spring 2 M. An

upwardly extending arm of the bell crank is joined by a link 2H5 to the arm 12% of the ieedroll. When the .treadie -rod is drawn down,,the movement is yieldably transmitted to the arm swing the iced-roll toward the nozzle. Because of the pivoting. oi the arm about the driving shaft QE t-his talresplace without interference with the gearing As to the corresponding movement of the finger Hit by the treadle-rod, a

short, inwardly projecting portion of the supporting arm led (Fig. .13) has pivoted to it a extending arm or the lever was connected to the treadle-rod. When the'rod'is drawn-down,

the lever 224, acting through the spring 2M and link 220, yieldably swings in the supporting arm HM to bring the surface see-or the ringer into contact with the outer face of the channel-flap to lift it and force it toward or into-engagement with the nozzle-section so. The extent of movement of the finger toward the nozzle is limited by contact of a surface 232 '(Fig. 13),. upon the arm [M with the machine-head. This shifting of the finger by movement of the arm it in no Way interferes with thefiap-smoothing oscillation im-. parted to saidfinger through the lever 168.

Since, during the use ofthe machine, this oscillation continues uninterruptedly, a balance of the elements may he estahlished which will minimize vibration of the apparatus as a whole.

At this time, the pin contacts withthe bottom. of the slot, swinging the lever 23 iand rotating the shaft ifiii to open the valve. As a result of this sequentialoperation; the-.roll 522 is first brought lightly against the work ancLuponcontinned depression ofthe rod, produces its feeding movement, with the channel-flapforced in'proximity to or against the nozzle, and then, and only then, cement is delivered by the nozzle to the channel. Conversely, uponrelease of the .treadlerod, the flow. oicem'ent is topped, and a m the work releasedlbythe feed-r011 and finger.

=In'the meet this apparatus, the feed-roll I22 is soadjusted hy'manipulation. of the lever I48 that the flat end-surface; of said roll will lieclose tothe nozzle-sections 39,32 but will clear the edge of the soles or a shoe to ,beoperated upon, whatever may be its extension or'thickness. When in its active position; as shown in Fig. 7, theperiphery of theroll willbe in position to engage'the shoe-upper U in proximity to the :crease. The fiapapressing finger i613 may beso located upon its holder-lever 110 that the surface I82 of the finger head .will'b'esuificiently separated from the edge 59 of the nozzl-section 3% to give a space through which the finger may have its flap-pressing movement. The finger may be more exactlyadjusteieven when the machine is in operation, by'shifting' the readily .moved eccentric ar n 2%; By altering the angle of the holder-leverl'lfi upon the carrier lever 558 by turning the screw M2, the edgelll i of the fingerhead i813 may be adjusted along the'edge 55 of the.

nozzle-section fililto cause this portion of the finger to lie.sufliciently close to the tread-surface of the sole to insure liftingthe. channel- ,flap, without excessive pressure upon the sole.

It should be observed thatsince the nozzle is stationary, adjustment-of either the feed-roll or the finger is without effect upon'the relation of the other of theseelementsto thenozzle, which need not he disturbed'unles" its; adjustment is desired.

With themachine in operation, thefee'cl-roll is rotating and theringer is oscillating-constantly, but normally both are. raised by the rod, ml,- under theinrluenceof the customary treadlespring, to the'positions illustrated in Fig. 4 of the drawings 7 the sole, assembled with its upper, tothe nozzlesection the nozzle-point ill lying at the root at of the channel, (Figs. fland 3), and the sole being substantially horizontal, in which position it may best be seenand manipulated. I The slot 84 in the nozzle-section32 is drawn yield'ably by. the spring into-delivering relation with the channel-oed b. Upon lowering thetreadle-rod, the connections to it swing down the arm Silt to bring the rounded edge l2! of the roll 122 into con-' tact with the shoe-upper carry in the supporting arm led to present the surface 32 of the finger l 66 in pressing relation to the channelfiap c. Thework thus being ready for advance, the rod-connections open the valve act; ,so cement .is delivered through thenozzle slot 58 to the inner face of the channel-flap, through the slot B l to the channel-bed and through the passages fitiandiilt to ,theroot of the-channel. The operator; aided by the rotation of the roll l2'2, feeds the work forward, the nozzle-point E'l serving as a gage throughout its travel. The fingerhead 4%, acting in its oscillation between the sole and. thelaid-back flap, raises the latter, yie1ding if the rounded edge ,ii-A contactswith the out the wrinkles, which were produced when the channel was opened, and positions the flap to re ceive cement from the slot v 8. As the channel is moved along the. noz-Zla'the walls ofthe slot 35 in the section 32, under-the influence of the spring Sim-float over. the .channel-bed, accommodating themselvesboth to thechan'ges of transverse contour and the angle of the channel resulting from the differing former the bed, as between the iorepartwandshank, and .from the positionin operator applies'the channel of r j tread-surfaceof the sole, and forces theflap up i f to thejnozzleesection ill at 553. This smooths which the operator holds the work; The action will be better understood upon comparing the showing of Figs. 8 and 14 of the drawings, in which the nozzle appears, respectively, in co-operation with the channel at the forepart and at the shank of the shoe. The effect of the spring upon the section 32 also causes this to respond to changes in the contour of the bed which might be too abrupt for the operator to follows We: the forepart of the shoe, in its feed, is rocked on the gage-point 51 of the nozzle, theupper will move over the edge [2| (Fig. 4) of small curve-- ture of the roll I22. At the shank, the increased rocking made necessary by the form of the shoe will transfer the area of contact to the. rollperiphery I23 of greater curvature. In each instance. these lateral movements. through different angles and in the change from one tothe other, will, because of the corresponding curvatures of the roll-periphery and their blending into each other. be effected smoothly, without interference with the advance of the work. Having'coated the entire channel, the operatorreleases the treadle-rod I01, which is raised by its spring. The valve I04 is first'closed. then'the feed-roll and finger are returned to their elevated positions clear of the nozzle. and the com leted work may be removed from the machine. If the operator wishesto clear the nozzle in event of clogging, the roll-arm I26 may be secured by the latching pin I53, where it will not be daubed by dripping cement. At the closeof the working period. release of the clamping lever 22 allows the entire nozzle to be separated from the connection to the shaft-section M8 and from the head of the machine and be clamped upon the receptacle III]. with its cement-delivering portions immersed in the solvent.
