This invention relates to insole rib cementers and is designed particularly to apply cement to the inner surface of the insole rib and to the adjacent channel in preparation for the application thereto of a strip of reinforcing canvas.

For manyyears, leather insoles having integral ribs formed by channeling and erected from the body of the insole have-been reinforced by the application of a layer of canvas extending against theinner face of-the rib. More recently, it has been found desirable to substitute strips of canvas for the over-all reinforcing and, in preparation for the attachment of such strips; it is customary to apply an adhesive, hereinafter called cement, to the inner face of the rib, the adjacent channel and a small portion of the midsurface of the insole. One highly satisfactory machine r that P po e is described in Letters Patent of the United States No. 2,400,'163,granted May 14, 1946, upon the application of Hans C. Paulsen. In that machine, the application of cement is eifected by means of a roll mounted on a horizontal axis with its end engaging the face of the rib. In order'for this machine to deal with the rather sharp curvature at the toeof the insole, it is necessary to use an applying roll ofv small; dimensions and, whilethe machine operates satisfactorily with a small roll, it increases the cost of manufacture and the possibility of breakage.

Accordingly, an object of the present invention is to devise a less expensive and more rugged machine of this type. r a

In accordance with a feature of the invention,- the feeding of insoles having pointed toes is facilitated by applying the coating by means of a roll rotating about a vertical axis. This roll is arranged to grip the rib against the end face of an opposed feed roll and can easily-handle ribs having a sharp curvature.

In the illustrated machine and in accordance with other features of the invention, cement 'is supplied to the periphery of the coating roll. by means of a nozzle and the'spreading of the cement in the channel is aided by a non-rotatable member positioned inside the applying rol1 and at its lower end. This spreader and the roll itself are individually yieldable heightwise to care for variations in thickness of the work and to enable a sure contact therewith throughout the cycle of the machine. I v 1 These and other features of the inventionwill best be understood from consideration of the fol lowing specification taken in connection with the accompanying drawing, .in which a Fig. 1 is a side elevation of the head of the machine with the cover removed therefrom;

Fig. 2 is a similar view, but on a larger scale, of the work-engaging parts in their operating position;

Fig. 3 is an angular view, looking at the end portionof the parts shown in Fig.2; Fig. 4 is a detail horizontal section through the lower end of the applying roll on the-line IVIV of Fig. 2 but enlarged and looking down upon a portion of a piece of work; i

Fig. 5 is'an angular view of the applying the nozzle and other associated parts; Fig. 6 is an end elevation of these parts; f Fig. 7 is a vertical section on astill larger scale through the coating roll and its supplying nozzle; Fig. 8 is a section through the nozzle on the line VIII-VlIfofFigJl; and j Fig. 9 is a greatly enlarged view ofthe bottom end of the applying roll, in inverted position, with the parts associated therewith. As will be seen from Figs. 2 and 3. the machine is arranged to apply a coating of cement to the inner surface ll) of a rib [2 formed by channeling an insole l4 and sticking the erected channel flaps together. It is also arranged to apply cement to the bottom of the inner channel "5 and to an adjacent margin I8 01' the surface of the mid-portion of the insole. When the work is in position in the machine, the feather 22 of the insole is gripped between a feed roll 24 mounted at the outer end of a horizontal shaft 26 and the periphery of a supporting roll 28 carried on, a shaft 30 in a tiltable arm 32. The rib fl2jis gripped between the periphery of a coating. roll 34 rotatable about. a vertical axis and the'end surface of the feed roll 24, and means are provided for spreading the cement deposited by the roll 34, as will be later described. This coaction of the rolls 24 and 34 is particularly valuable where sharp-toed insoles are to be treated, espe-"' cially if the ribs have been slashed at the toe. In that case, the vertical roll 34 grips the s'uc-,. cessive slashed portions against the endof the roll 24 and feeds the insole without difliculty.

The shaft 26 of the feed roll 24 is journaled in a web 36 extending outwardly from the side ofa hollow frame38 (Fig. 1) and, within this'frame, there is anarm 40 in which there is journaled a drive shaft 42 connected to the roll shaft 26-by oll,

means of gears 44 and 46. The arm,32 in which the'supporting roll shaft 30 is journaled is tiltably mounted betweenpivot screws 48 extendingflin wardly from ears 50 formed on the inner sideof the frame. Rolls 24 and 28 are connected to turn When the operator presents a piece oi work t themachine, he depresses a treadle connectedtoa treadle rod 66, thereby tiltingpa lever 6& which has an upwardly extending..a.'rrn .';'tll' andlwi'sJal'so connected to a rod 12 yieldably engaging-an, ex: L

tension 14 of the tilting arm 62. The movements This roll itself is received in an enlarged recess I32 (Fig. 7) in the block 60 in which there is positioned a coil spring I34 surrounding the sleeve I20 and urging the roll downwardly. This downward movement is limited, however, by a collar I36 held at the upper end of the sleeve I20 by a setscrewIIiB. Brovision isthus made for a limited upward; moveincntz 'oit the; coating roll such as may be required 'by'thicker work. Within .the sleeve I20 there is a vertical rod I40 the lower end of which has an enlarged portion constituting aifixed spreader I42 to aid in coating the channel.

On the upper arm of this bell crank I92 is a flanged stud 200 which is positioned for engagement in the forked end 202 of a rod 264 (Fig. 1) which is slidably mounted in the side of the frame 38 of the machine and is normally pressed outwardly therefrom by a spring 266. A collar 208 limits the through a flexible tube 2I2' (Fig; 1) which is clampedto a supply pipe 2I4 having at its'lower end-asleeve 2| 6 surrounding a'hollow stud 2I8 which communicates with the passage 2). The mid-portion of this stud'is' reduced, and two pas sages 220 at right angles to each other connect the reduced portion of the outside of the stud to the central passage therein. This arrangement permits free swinging movement of the supply pipe and the tube as the block 60 is moved in and out and does not interfere with the positioning of the "nozzle with respect to the applying roll.

Adjustment of this positon is effected by loosening a clamp screw 222 (Fig. 7) threaded in the nozzle body I84 and passing through the slotted end of a mount 224 the face of which is groovedto coact with a rib on the body portion I 64. In this mount is a stud 226 held in position by'a setscrew and the stud passes through an outwardly extending portion of a support 228 (Fig. 6) adapted for heightwise adjustment upon the block66 with the aid of a rib 236 after'which the support may be secured in adjusted position by means of a clamp screw 232 passing through an elongated slot in this support. The tilted position of the nozzle upon the support 228 to bring the outlets I" close to the roll 34 is maintained-by a drawbolt 234 in the support engaging the side of the stud 226.

As will be plain from Figs. 1 and 2, the nozzle I14 is mounted on the near side of the applying roll toward which the ingoing work moves as it is 'fed'forward, and it will be noted from Fig. 2' that an extension lip 236 is provided on the lower end of the nozzle which rests in the channel I6 of the insole and helps to hold the latter against the supporting roll 28 so that, if the insole happens to be made of poor material, there will be less opportunity for the feed wheel 24 and the applying roll 34 to ride accidentally over the rib. It frequently becomes necessary to supply the latex in such quantities that the applying roll is flooded and, then, in order to prevent the latex from working up between the side of the applying roll and the recess I32 (Fig. 7) in which it rotates, the periphery of the roll is provided with a helical groove 238 tending always to push the latex downwardly out of this joint.

As a further aid in spreading the cement which has been applied to the insole, there has been provided a tiltable drag 240 surrounding the far side of the applying roll and hence its leaving side, considered with respect to the direction of movement of the work as indicated by the arrows in Figs. 4 and 9. This drag 246 tapers downwardly toward the leaving side of the roll and terminates in a depending lip 242 (Figs. 6 and 7) 6 which rides in the channel I6" for the reason that the drag is tiltably mounted upon a screw 244 and is urged downwardly by a spring 246 to bring the lip portion 242 against the work. The lip 242 is not quite as wide as'the channel to avoid binding on the work at the toe end thereof. In order to provide for adjustments in setting 'up the parts of the machinewhich are associated with the applying roll 34, the pivot'screw 244, passing through a sleeve 248 (Fig. 2) which is integral with the drag 240, is threaded in the lower end of a hanger 250 (Fig. 3) adjustably attached to the side of the block 60 by a screwand-slot connection 252. The upper end of this hanger 25B ,is received. in a recess 254 in the block 60. It will also be seen. from an inspection of Figs. 2 and 3 that the drag 240 has an integral flat plate 256 on the upper portion of which there is adjustablyattached by screws a strip 251 (Fig.

6') having an outwardlyextending. ear 258 to which one end of .the spring 246 is attached. The other end of the spring is looped about. a pin 260 in the block 60.

p In the operation of the machine, an insole turned with; its heel end away from the operator is moved laterally until itgperiphery-contacts the edge gage 90. If, however, we are dealing with a so-called cookie insole, then, the screw 94 will be loosened-and this edge-gage moved out of the'way to prevent interference with the extension inthe shank of that kind of insole. At the. same time, the outside of the' rib I2 is pressed against the guide 92 and; the treadle depressed which will raise the supporting roll 28 to lift the feather of the insole into contact with the'under side of the feed roll 24 and the channel of the insole into contact with the tip 236 on" the nozzle and with the bottom end of the applying roll. This action will also be accompanied by a movement, to the right, of therod 84 which will slide the block 60 and draw the applying roll 3 1 against the inner face III of the rib where it will be rotated in such a direction that its periphery moves with the rib of the insole asthe latter is carried awayfrom the observer in Fig. 1.

Since theinward movement of the block 60 will also be accompanied by an opening of the valve H8 in the nozzle. the coating material will flow through the outlet openings IIl into contact with the side face of the applying roll 34, entering the grooves I46 to flow down against the insole and through the passages I48 (Fig. 9) into the,

annular portion I50 at the base of the applying roll. The cement will then be spread upon the mid-portion 20 of the insole to form the marginal band I8 with the assistance of the grooves I44 in the lower end of the spreader I42 and will be spread out in the channel I6 by the ribs I52 and the extension I54 also at the lower end of this spreader.

Variations in thickness will be accommodated by the upward yielding of the spreader I42 against the resistance of the spring I64 (Fig. '7) and the roll 34 itself may yield upwardly against the resistance of the spring I34. A further spreading action is accomplished by the depending drag lip 242 which is held in yieldable engagement with the work by the spring 246.
