The nozzle 2i is'i supported on a han er H14 (Fig. 1), (shaped somewhat like a Lorraine. .oross) which isfjoinedto the member 98 by upper and lower pairs ofparallel links H16, I01 thus permit.

ting upward nioye nent ofthe nozzle against the" compression of a spring I08 carried by bent rods I09, III. A carrier III) for the nozzle is notched to receive the lower end I I2 of the hanger I04 and this notched portion is joined to the hanger by a horizontal pivot pin II4 (Figs. '1 and 3). The proper positioning of the band of cement upon the margin of the sole, a narrow clean margin outside the cement being usually desired, is determined by a guide roll I I6 freely rotatable upon a vertical pin I I8 in the nozzle carrier. This roll rests against the peripheral edge of the platform sole I2 as shown in Fig. 1. The heightwise position of the nozzle carrier is determined by a roll I20 (Figs. 1 and 6) riding upon the bottom of the shoe and freely rotatable upon a screw pin I22 threaded in a thick plate I24 which is a part of the nozzle assembly.

The nozzle 20 comprises a plurality of identical applying fingers I26 having thin midportions (Fig. to reduce friction and gumming. These fingers are tiltable upon a pivot pin I28 passing between an outer side flange I30 and an inner side flange I32 of a delivery block I34 and these parts I24, I26, I34 together with a frame plate I36 are mounted upon the nozzle carrier IIO by means of screws I38 (Fig. 3). The delivery block I34, and the frame plate I36 have a cylindrical passage to receive a hollow stem I40 projecting laterally from a block I42 into which is threaded a nipple I44 to provide for the connection thereto of the supply tube 22 (Fig. 4). The open end of the stem abuts the carrier IIO (Fig. 3) and a packing I46 received in a groove in the outside of the stem I40 prevents leakage of the fluid cement as the nozzle carrier and the nozzle rock with respect to the stem.

The block I42 and its stem I40 are held in place on the frame plate I36 by means of an outer.

frame plate I48 joined to the other frame plate I36 by means of screws I50, I5I which pass through spacer sleeves I52. The fingers I26 are urged downwardly, until their transverse portions contact the upper side of the block I34, by means of wire springs I56, the ends of which are wrapped around and thus secured to a cross pin I58 while their free ends are curled at- I60 (Fig. '4) andreceived in grooves in the upper faces of the fingers I26. Displacement of the springs about the pins is prevented by an abutment pin I59 bearing against the midportions of the springs.

' The trailing side I62 of the spacer block I 34 is curved about the center of the pivot pin I28 and the forward edge face I64 of each finger is similarly curved to rest against this curved face I62. The hollow stem I40 has a vertical slot I66 opposite the center of each finger and in the spacer block I34 a small passage I68 opposite each of these slots communicates with the curved face I62 and then with a recess I in the inner face of each finger which is joined by a passage terminating in an outlet or delivery point I'I2- opening into a groove I14 in the bottom workcontacting face of each finger. It will be noted that the fingers are lifted against the tension of their springs I56 to conform to the shape of the bottom of the shoe as the height-measuring guide roll I20 determines the spacing of the nozzle as a whole from the work. The motion 01' the fingers is relatively small and in whatever position they assume within the scope of the apparatus the cement will flow freely through the passages I68 and out of outlets I'I2 into the grooves N4 of the applying fingers. It will be noted that each of the individual fingers I26 is provided with a tail I80 to prevent the finger from 4 dropping off the edge of the sole as the nozzle approaches the shank portion by contact with the work near the point of delivery, as illustrated in Fig. 2 and that these tails also may contact the springs on pin I58 to limit the upward movement.

In the operation of the machine upon a particular shoe which is mounted upon its support I6, the cement will flow through the tube 22 to the block I42 and thence through the nozzle fingers onto the work. This nozzle, if used in the machine of the parent application, will be carried about such a fractional portion of the periphery of the shoe as is desired and will be guided heightwise by the roll I20 and laterally by the guide roll II6, the latter being held by a spring, not shown, in contact with the periphery of the sole. As the nozzle rides around the shoe, the individual fingers will yield heightwise as necessary so that they are always in contact with, the platform sole I2 and thus may be depended upon to deliver a uniform band of cement through the whole width of the margin I0. The chain which supports the nozzle will hold it in its approximate position by action of the guide tracks 36, 40 and their grooves, the chain being driven by power. Inasmuch as the hanger 90 which supports the nozzle by means of parallel links is rigidly integral with one of the links of the chain, then the row of nozzle outlets I'I2 (Fig. 5) will maintain an approximately radial position with respect to the periphery of the sole. As the nozzle reaches the place where it is desired to stop the band of cement the power delivered to the chain is cut off by the operator.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

' l. A coating nozzle comprising a fixed block having a supply duct adapted to be connected to a source of coating material, yieldably mounted fingers on the nozzle having work-contacting faces and having other faces sliding along a surface of the block, said fingers having passages from said sliding faces to their work-contacting faces, said block having matching passages from the duct to the aforementioned surface of the block adjacent to the fingers, one set of passages being elongated adjacent to the meeting ends of said passages to permit relative movement therebetween without disconnecting the passages.

2. A nozzle comprising a series of fingers mounted on a horizontal pivot and extending laterally therefrom, to permit swinging toward and away from a piece of work, and a block having an arcuate face, a transverse duct, and a series of passages from said duct to the arcuate face, said fingers having curved faces concentric with and meeting the arcuate face of the; block and having other work-contacting faces,

said fingers also having a series of passages interconnecting said faces, one of said series of passages terminating at said meeting faces in grooves extending in the direction of swinging movement of the fingers to provide a continuous connection between the passages in various positions of the fingers.

3. A nozzle adapted for traversing movement with respect to the upper surface of a piece of work, said nozzle being provided with a horizontal pivot and comprising a block having a transverse duct and an arcuate face upon the trailing side thereof which is concentric with said pivot. -said block having passages between the duct and the arcuate face, and a series of flat fingers car ried by the pivot having curved faces adjacent to their trailing ends extending downwardly past said arcuate face in sliding engagement therewith, said trailingv ends terminating in workengaging faces and having passages between said faces which are adapted to be alined with the' passages in the block.

4. A nozzle comgrising a series of fingers arranged side by side and pivotally mounted for taining said fingers in contact with the work, means for delivering coating material to the curved work-contacting faces of the fingers, said fingers having upturned tails the lower surfaces of which form extensions of said work-contacting faces to limit the downward displacement of the fingers by contact with portions of the work near the point of delivery.
