Serial No. 334,254.

@ locked with each other in succession by the movementof a slide which embraces the two stringers, and to be disengaged fronieac-h other successively by movement of the slide in the opposite direction;

In order that the strips which constitute the stringers for the" fastener may become firmly united during vulcanization to the quarters or flies of the overshoes' in which they are incorporated,- it is important that the fabric strips should be" uniformly andcompletely coated with rubber cement. It has been found most convenient to apply the cement to the fabric strips after the jaw members and slide have been assembled thereon and while the two fabric strips are joined at their proximateedges by the intercalated jaw members of the fastener; The two fabric strips are permanently joined atthe lower part of the assembly andthen their opposed marginal edges are engaged by movement of the slide to the upper end of the assembly. Substantially all the surfaces of the fabric strips overlap or extend into the margins of the flies of the oversh'o'e while the intercala'ted series of jaw members project slightly beyond the edges of theflies. lVhi leit is important to coat thoroughly the entire area of the fabric strips, it is equally important to leave the fastener members,

which constitute in eiiect a longitudinal rib in the workpiece, free and clear from cement.

In one aspect, my invention contemplates a machine designed for coating rapidly, accurately and uniformly throughoutarea upon both sides of the rib such a work piece as that described. An important feature of the invention contributing to this result consists in spaced work feedi-iig niember'sjaiid means for maintaining a supply of liquid adhesive located above the work and having provision for flowing the adhesive by gravity upon a selected area of the work as it is ademcee by the feeding members. Such a machine is adapted for continuous operation upon work pieces presented in" rapid" siicc es sion to the machine. Moreover, it permits the source of liquid adhesive to be located close to the point of application so" that a umform supply is insured and the under tainty of intermediate ti'ans'ferringniechanism' is obviated.

Another important feature of m invention consists in the provision or separate units, each including a driven work feeding member and means for delivering liquid ad'- hesive over a" defined area of material edvanced by the feeding means.- An advantage of this construction is that the-units may be relatively and bodily adjusted Without disturbing their operative organization and thus the location of the bands of applied adhesive may be varied to suit therequireinents of the work. This is particularly ilisetul in ha-ndling ribbed workpieces of the character desc'ribed', in' that the units may be arranged to yield to permit the passage of the fastener slide or other irregularity in the effec the width of the ribwithqut interrupting the continuous application of the adhesive. Myin'vention also includes'improyedmeans' for feeding' a ribbed work strip, The fe ding means is exemplified in the illustrated embodiment of the invention by a paif of spaced disks driven-about vertical axes and arranged to engage the work on either side of its rib, combined with a supplementary feeding member arranged tofact upon the rib itself as the work passes from the feed disks. As herein shown, the supplementary feeding member comprises an endless-carrieroperating. in a path substantially tangential with respect to" the disksand serving. to advance the w rkp y regent a t ve 9 t e disks. This arrangement facilitates the continuous presentation of work by the operator to the machine and improves the accuracy of its travel through the machine. This combination of feeding means acting upon the margin of a ribbed strip with other feeding means acting upon its rib has not been known heretofore and is believed to be broadly novel.

Preferably, the feeding and adhesive-applying units of the machine are carried at the free ends of a pair of pivotally mounted arms and the feeding disks are driven by mechanism disposed concentrically with the axis about which the arms move. This construction permits the relative adjustment or temporary separation of the units without in any way interfering with their driving connections and constitutes simple and reliable mechanical construction for effecting the desired results.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which Fig. 1 is a plan view of the machine;

Fig. 2 is a view in longitudinal section;

Fig. 3 is a view in rear elevation, partly in section;

Fig. 5 is a View in perspective on an enlarged scale, of the mounting for one of the cement reservoirs; and

Fig. 6 is a view in cross section, on an enlarged scale, on the line 6-6 of Fig. 1 looking toward the rear of the machine.

As already stated, the illustrated machine is designed for applying two bands of rubber cement to a work piece which comprises the fabric strips 94 of an overshoe fastener which are permanently secured together at one end by afastening member 97 and are connected at their proximate or meeting edges by two series of intercalated jaw members 95. These are engaged with each other, or disengaged, by the movement of a slide such as the slide 96, shown in Fig. 1. The work strips are fed in successively from the front of the machine and are advanced by the operator to a pair of flat, rotary feed disks 34 and 134 and their margins pass beneath the two cement reservoirs 42 and 142, from which cement is discharged so as to form two continuous bands upon the fabric strips 94, one located on either side of the longitudinal rib formed by the metallic fastener members 95. As the work leaves the feed disks 34 and 134, it is immediately engaged by a supplementary feeding device comprising an endless belt 82 and transferred to a belt conveyor which removes it from the machine.

The machine comprises a bed plate 10 having bearings for a horizontal drive shaft 12 which carries tight and loose pulleys on its outer end, as shown in Fig. 1. The shaft 12 carries at its inner end a bevel pinion 14 meshing at its lower side with a bevel pinion 18 which is pinned to a vertical shaft 20 journaled in brackets 24 and 25 secured to the bed plate 10. Pivotally mounted to swing upon the upper portion of the vertical shaft 20 are two horizontal arms 30 and 32. The arm 30 is forked so as to embrace the end of the arm 32 and the arm 32 is forked to embrace a pair of sprocket wheels 26 and 28, the upper of which is pinned to the shaft 20 and turns with it and the lower of which is fast to the upper end of a sleeve 22 which, at its lower end, carries a bevel gear 16 driven by the bevel gear 14 at its upper side. The bevel pinions 16 and 18 are of the same size and, accordingly, the sprocket wheels 26 and 28 are driven at equal speed and in opposite directions.

Each of the arms 30 and 32 is forked at its free end and carries a stationary vertical shaft 36 or 136. Upon the shaft 36 is journaled a sleeve 35 having a fiat disk 34 at its upper end and a sprocket wheel 38 secured to its lower end. The sprocket wheel 38 is connected through a chain 29 to the lower sprocket wheel 28 on the drive shaft 20 and the disk is, accordingly, continuously driven thereby regardless of the angular position of the arm 30 aboutthe axis of the shaft 20. The arm 32 which carries the shaft 136 is similarly provided with a disk 134 mounted upon a sleeve which is driven by a sprocket chain 27 from the upper of the two sprocket wheels 26 on the drive shaft 20. The two arms are connected by a tension spring 31 which tends at all times to move them together. In this movement they are limited by adjustable stop screws 58 and 158 projecting outwardly from an angular bracket 56 secured to the bed plate 10. The spring 31, therefore, acts to hold each of the arms against its respective stop screw while permitting it to yield and swing outwardly at all times. The disks 34 and 134 are normally spaced from each other by a distance substantially equal to the width of the rib formed by the fastener members 95. The degree of separation may be regulated by setting the stop scr-ews 58 and 158, as will be apparent, or the position of both arms together may be adjusted in a transverse direction.

The shaft 36 has secured to its upper end by a set screw 41 an arm or bracket 40 having a square-sided recess in which is adjustably mounted a sliding block 44 in which is inserted the delivery end of an overhead cement reservoir 42. The lower end of the reservoir is converted by an angular plate 48 into a duct for discharging cement directly upon the sur face of the disk 34 in a defined segmental area adjacent to its periphery or upon the surface of the work piece carried by the disk. The reservoir 42 is radially adjustable with respect to the disk by reason of the sliding block 44, which may be moved in the recess of the arm and clamped in. adjusted position by the set screw 46. By the radial adjust ment of the reservoir the location of the band of cement applied to the work may be controlled and brought nearer to or further from the line of the fastener members 95.

The arm 40 carries a forwardly extending projection having'a downwardly extend ing flange 52 on its lower surface which eX- tends parallel to the direction of feed and engages the surface of the work plate 91. The flange 52 acts as an edge gauge, contacting with the edge of the fabric strip 94 and guiding the work in a straight line path into the range of the feed disks.

The shaft 36 carries at its lower end a bracket having a hub with a plane lower surface and arranged to slide upon a transverse bar 54 secured to the bed plate 10. The

bracket 60 carries at its outer end a forked upright arm 62, in the upper end of which is mounted a series of parallel scraper plates 64. As herein shown, three of these plates engage the upper surface of the disk 34 and three engage its lower surface and edge. The action of the scraper plates 64 is to remove from both surfaces of the disk 34 all surplus cement and return it to a receptacle 66 carried by the bracket 60, from whence it is returned by a pipe 68 to a suitable storage container. When the machine is operating with no work under the reservoirs, the full charge of cement will be carried to the scrapers and removed from the disk by them. When the work is passing through the machine upon the disk 34, however, the entire charge of cement is delivered directly to the surface of the work piece.

The shaft 136 carries a reservoir 142 and scrapers 164 corresponding to those carried by the shaft 36. It will be apparent that each of the arms 30 and 32 carries a complete unit comprising a driven feed disk, a

cement reservoir and scraping mechanism and that in the pivotal movement of the arms these units are carried intact toward and from each other without any disturbance of their various functions, the only effect being to locate the bands of applied adhesive closer to or further from the'centrally disposed rib of the work piece.

Auxiliary or supplemental work-feeding means are provided in the shape of an endless belt 82 and two conveyor belts 90. Secured to the forward part of the bed plate 10'is an angular bracket 70 providing bearings for a iorizontally disposed drum 72 having a central grooved pulley for the endless belt 82. This is driven by a pulley 74 upon a transverse shaft 76 j ournaled in bracketsextending beneath the bed plate 10 and having at its outer end a sprocket wheel which is driven by a sprocket chain 7 8 from a sprocket wheel on shaft 12 located inside the fast and loose" feed disks 34 and 134. The belt 82 is substantially triangular in cross section and engages the rib of the work by its upper flat surface. The bed plate carries another bracket 84 in the upper end of which is mountd a k 86 providing bearings for an idle roll 88 located above the roll and cooperating with the feed belt 82 to engage the rib of the work piece as it leaves the feed disks 34 and 134 and advances the work to the belt conveyors 90.

The drum 7 2, as already explained, is driven through the belt 82 and the shaft 7 6 by the sprocket chain 78. The drum 72 also drives the two flat conveyor belts 90 which are spaced from each other so as to receive the rib of the work piece between them and which serve to carry the work piece out of the machine.

At the entering side of the feed disks, the mahine is provided with a stationary work plate 91 supported by rods above the bed plate 10 and covering the arms 30 and 32. The plate 91 is provided with a centrally disposed groove or channel to receive'the rib formed by the fastener members95, thus permitting the fabric strips 94 to lie flat on the surface of the plate. The plate extendsrearwardly between the feed disks and into proximity to the roll 88, as shownin Fig. 4. In the sectional view of Fig. 6, only the material at the bottom of the groove in plate 91 appears. The plate cooperates with the flanges of the projections 50 and in guid ing the work properly to cementing position.

The operation of the machine will be understood from the foregoing description but may be summarized as follows. The work strip to be cemented is placed upon the work plates 91 by the operator, with the fastener slide at the rear, and pushed toward the right, as seen in Fig. 1, until its margins are engaged by the feed disks 34 and 134 which are rotated in the direction indicated by the arrows in Figs. 1 and 4. Previously, the arms 30 and 32 have been adjusted transversely to accommodate the work in hand and thereservoirs 42 and 142 have been filled with cement. When the work piece has been moved into the range of the feed disks 34 and 134, it is drawn towardthe right and two bands of cement are discharged directly upon its surface by the ducts forming the lower ends of the reservoirs. As the work strip passes fromthe feed disks, it is immediately engaged at its central rib by the driven endless belt 82 and idle roll 88, so that the 'portion of the work strip leaving the disks is kept taut and advanced until it reaches the belt conveyors 90'. By these, the cemented work strip is carried from the machine to a drying beltor: other placeof disposal. During the passage of the work through the machine the rib passes bet-ween the spaced edges of the feed disks 34 and 134 which are free to be displaced outwardly to permit the passage of the fastener slide 96, which is wider than the fastener rib itself. If it is desired to cement both sides of the margins of the fabric strips 94, the work piece is reversed and passed through the machine a second time after the cement has become partially dried.
