APPARATUS FOR USE IN SHOE MANUFACTURE Filed March 7, 1951 3 Sheets-Sheet 2 May 11, 1954 J. s. KAMBQRIAN APPARATUS FOR USE IN SHOE MANUFACTURE Filed March 7, 1951 3 Sheets-Sheet 3 Patented May 11, 1954 OFFICE APPARATUS FOR USE IN SHOE MANUFACTURE Jacob S. Kamborian, West Newton, Mass. Application March 7, 1951, Serial No. 214,318 19 Claims. (01. 12-17) This invention relates to apparatus for use in shoe manufacture and more especially to the manufacture of the California or slip-lasted shoe.

In the manufacture of the foregoing type of shoe, the upper, sock lining and wrapper strip are joined in inally by a line of stitches with the wrappe strip folded upwardly against the upper. Adhesive is then applied by hand by means of a brush or the like, to the heel end portion of the sock lining, the heel tuck is laid on the adhesive coated surface either before or after the adhesive has dried in accordance with the type of adhesive used, and following this, the wrapper strip is turned by pulling upwardly or downwardly, depending upon the position of the shoe, so as stand upright from the plane of the sock lining. A platform together with a cushioning material if the latter is to be used, is then placed on the sock lining and tuck, the wrapper is folded about the edges of the platform and heel inwardly over their bottoms, and an outsole is attached to complete the bottom structure.

The orincipai objects of this invention are to provide apparatus for applying adhesive to a predeter 'ied area of the heel end portion of the sock ling prior to the application of the rel; piece without waste of adhesive, either by lying an excess of adhesive to a larger area than is necessary, or by a loss of adhesive through delivery of an excess thereof to the applicator so that it bleeds and drips to the floor or accumulates and becomes encrusted on the applicator it- Another object is to provide an applicator which may be used with equal success upon sock linings f arious size without adjustment or the need for substitution of an applicator of one size for another. A further object of the invention is to provide an iratus for holding the upper during the tion of the adhesive thereto and for thereafter pressing the tuck piece against the adhesive coated surface when it is laid thereon and holding it place while the wrapper is that at the end of the turning operation, firmly united to the sock lining and upper is ready for bottom treatment, and a means which is interposed between the d shoe after the latter is withdrawn, thereby preventing accidental dripping of adhesive on the work during the turning operation.

Other objects are to provide an apparatus of extr 'ne' simple construction which substantially eliminates direct contact of the operator with the adhesive, so that there is less likelihood of soiling the hands and/or the work; which protects the operator from accidentally touching the heated parts of the apparatus; which speeds up production by eliminating transfer of the work from one apparatus to another for successive operations of cementing and turning; in which the adhesive is delivered to the applicator its surface to spread under pressure and hence is always dependable in contrast to gravity fed applicators, and yet will not drip adhesive; and which may be manually operated, thereby eliminating an expenditure of power. Still further objects are to provide equipment in which the adhesive can be kept liquid throughout delivery from the container in which it is stored, to the point of application and is conducted through closed passages so as not to be exposed to the air, and hence may be kept in good condition.

In accordance with the foregoing objects and as herein illustrated, the device has a jack upon which may be placed a partial assembly consisting of an upper, sock lining and wrapper strip stitched along a common margin with the exposed side of the heel portion of the sock lining uppermost, and an applicator arranged to apply adhesive to a predetermined area of the sock lining at the heel end. The foregoing parts are arranged for relative movement about axes at right angles so that the applicator may be moved into contact with the shoe part on the jack and while in contact therewith, may be moved over the adhesive. The applicator has an acting face shaped to engage the central area of the heel end of the sock lining, leaving a substantially horseshoe-shaped area, marginally of the sock lining, and has delivery orifices peripherally of its acting face through which the adhesive is expelled outwardly over the horseshoe-shaped area which is to be'coated, adhesive being excluded from the central portion of the sock lining by contact of the acting face of the nozzle therewith. A container for adhesive is connected by a conductor to the nozzle, and a combination valve and pump is interposed between the container and the nozzle which is adapted to supply the adhesive to the nozzle under pressure. A presser foot is carried by the nozzle and is selectively movable therewith into engagement with the jack. Normally, during application of the adhesive, the presser foot is held deflected in an out-of-the-way position. There is means, however, for swinging the presser foot into operative position when the nozzle is lifted away from the jack without disturbing the orientation of the nozzle, so that a portion of it under lies the acting face of the nozzle and accordingly, when the nozzle is again moved toward the jack, the presser foot will engage the jack ahead of the nozzle for the purpose of pressing the tuck piece against the tacky surface of the sock lining and will hold it during the turning operation.

The invention will nowbe described in greater detail with reference to the accompanying drawings, wherein:

Fig. 5 is a plan view of the apparatus shown in Fig. 3, looking down at the top thereof;

Fig. 6 is a vertical diametrical section through the applicator, showing the details of the combination valve and pump;

Fig. 7 is a bottom view of the applicator nozzle; and

Fig. 8 is a perspective view of the bottom portion of the upper at the heel end, with the upper partially turned and with the tuck broken away to show the area to which the adhesive is applied.

Referring to the drawings (Fig. 3) the apparatus has a rigid base plate I0 suitable for attachment to a bench or table from which rise fore and aft, pedestals I2 and I4. A jack I6 is bolted in an upright position to the forward pedestal and has at its upper end a forwardly and downwardly inclined plate I8 which corresponds substantially in shape to the heel end portion of a shoe for reception of a partial shoe assembly S consisting of an upper u, sock lining l and wrapper w joined along common margins by a line of stitching t with the wrapper strip folded upwardly against the upper. The partial assembly is placed, foot opening down (Fig. 1), so that the plate I8 engages the inside of the assembly at the heel end.

The rear pedestal I4 rises upwardly from the base plate beyond the upper end of the jack I8 and has at its upper end a vertical socket 22 in which is set a post 24 having a head 30 at its upper end. A set screw 26 is threaded through the rear side of the pedestal and by rotation, its inner end may be brought to bear upon the post to lock it against rotation and to anchor its lower end in the socket. A block 28 is rotatably mounted on the post between the top of the pedestal and the head 30 of the post, and provides a support for a bracket 32. The lower part of the bracket is bifurcated so as to straddle the block and is fulcrumed on pivots 34 extending from opposite sides of the block for rocking movement about a horizontal axis and for swinging movement about the vertical axis of the post, for purposes which will appear hereinafter.

The lower end of the block 28 is shaped to provide a cylindrical surface 36 (Fig. 1) and in this surface there is formed a dimple 38 (Fig. 4). A plate 49 is secured to the pedestal so that a part thereof overlaps the recessed surface 33 opposite the dimple. At the inside of the plate there is formed a well in which is seated a stiff spring 42 for holding a ball 44 seated in the dimple. As thus constructed, the spring pressed ball limits rotation of the block on the post, that is the block will turn in either direction through a small angle but will be stopped by jamming of the ball against the shoulders of the dimple.

A container 46 for receiving a quantity of adhesive is made fast to the bracket 32 and has a cover 48 closing its top, and a false bottom 50 (Fig. 1). Extending forwardly from the container and integral therewith (Fig. 1) is a hollow arm 52 which provides an inclined passage 54 running lengthwise thereof, the upper end of which is in communication with the interior of the container 46. The outer extremity of the arm 52 terminates in a cylindrical boss 56 having a vertically elongate bore 58 therein, which is in communication with the lower end of the passage 54 in the arm by way of an opening 68. In the vertical bore 58 of the boss 56 there is disposed a hollow barrel 82 (Fig. 6) which has an external shoulder 54 engaged with the lower end of the boss 58. The upper end of the barrel is threaded at 88 and a cap 68 is placed on the threaded end and engages the upper end of the boss 58 so as to fix the barrel 62 in the bore in the boss. An opening or slot 10 (Fig. 1) in the wall of the barrel 82 affords a direct communication from the interior of the barrel by way of the opening with the lower end of the passage 54.

Within the barrel 62 near its lower end (Fig. 6), there is an internal annular shoulder I2 on which there rests an annular valve seat I4 having a transverse septum 15 provided with an axial bore 18 surrounded by a plurality of openings 80. A valve disc 82 having a stem 84 fast thereto and extending through the bore 18 is held against the under side of the septum I6 so as to close the openings 80. To this end, the stem 84 has at its upper end a head 86 between which and the web 16 there is mounted on the stem a compression spring 88. As thus arranged, the valve disc 82 will normally remain seated until positive pressure is applied from above it so as to move it away from its seat.

The lower end of the barrel 62 has an enlarged portion 90 to the end of which is fastened a nozzle head 92 by means of a cooperating dovetail groove 94 and dovetail 96 formed on the re spective parts. The nozzle head 92 has an end face corresponding substantially in shape to the heel end portion of the sock lining but is somewhat smaller (Fig. '7) so that when it has contact with the sock lining, it engages the central portion thereof, leaving a horseshoe-shaped margin peripherally of the heel end (Fig. 8). The nozzle head is hollow, having an opening 98 therein which forms a continuation of the chamber of the tubular barrel. A plurality of passages I80 extend laterally, downwardly from the opening 98 through the wall of the head and terminate in discharge openings or orifices I02 in the substantially vertical peripheral edge face I04 of the head 92. The bottom or end face of the nozzle head 92 has a flat surface I88 marginally thereof which when brought to bear upon the sock lining, as will appear hereinafter, prevents adhesive extruded from the orifices I02 from flowing inwardly between the end face of the nozzle and the work. The central portion I08 of the end face is concave so as to minimize the possibility of the marginal edge of the nozzle being held out of close contact with the sock lining by unevenness in the work. Thus adhesive extruded from the orifices I02 will flow outwardly therefrom so as to coat only the marginal portion of the sock lining as illustrated in Fig. 8.

Above the valve in the barrel there is located a plunger III! which has a rod H2 extending therefrom upwardly through the cap 68. A knob I I4 is fastened to the top of the rod I I2 and provides means for forcing the plunger III) downwardly in the barrel. A collar H6 is threaded on the rod below the knob H4 and may be ad- J'usted by rotation thereon to limit the downward movement of the plunger H0. A compression spring H1 is placed within the barrel 52 between the lower end of the plunger I It and the upper side of the valve seat 14 so as normally to hold the plunger III] at the top of the barrel with its lower end above the opening Ill in the barrel. Thus adhesive in the container 46 is free to gravitate through the passage 54 into the barrel 52 below the plunger I I0, but is prevented from running through the nozzle 92 by reason of the closed valve 82 until the latter is forced open.

The container 45, arm 54 and barrel 62 are kept warm by means of heatin elements. As illustrated, a heating element H8 is placed against the under side of the false bottom 56 of the container 46 and along the under side of the arm 52, being retained there and concealed by a cover-plate I29 fastened to the under side of the container at and arm 52. A hollow boss I22 is formed integral with the container 46 in which is placed a switch I2 and control I25 through which current is supplied to the heating element and the temperature thereof is regulated. A boss F28 is formed integral with the side of the barrel 62 in which there is placed another heatin element (not shown) supplied with current through a conductor I38. This latter heating element may be controlled by the same switch as the heating element I I 8 or by an independent switch.

As thus constructed, when it is desirable to apply adhesive to the heel end of a sock lining, the operator places the partial assembly on the jack, bottom up, then grasps the knob H4 and pushes down on it so as to bring the acting face of the nozzle 92 into engagement with the contral portion of the exposed surface of the sock lining by tilting the arm 52 and container id downwardly on the bracket 32. After the nozzle is brought firmly into engagement with the sock lining, the knob is further pressed down so that the plunger H moves downwardly in the barrel 62, closing the opening 60' and applying pressure to the adhesive within the barrel 62 below so that the valve 82 is unseated, and adhesive is extruded through the orifices I02 of the nozzle head. While thus held down, the applicator may be swung about the vertical axis of the post so as to slide the face of the nozzle transversely of the sock lining a limited amount, and hence to spread the extruded adhesive uniformly and into close proximity with the seam peripherally of the lining. This limited swinging movement is afforded by the spring pressed ball 44 seated in the dimple 38 (Fig. 4) heretofore explained, making it possible to use an applicator of a given size for shoes of several sizes within a given range of sizes, since it may be moved laterally enough in opposite directions to insure spreading the adhesive outwardly to cover an area larger than the actin face of the nozzle.

As soon as the knob I I4 is released; the spring H? returns the plunger III] to its top position, the valve 82 closes, and a slight vacuum is created below the valve 82 which serves to prevent adhesive from bleeding or oozing from the orifices I532. The applicator is returned from its depressed position to its elevated position by springs I25 to be described hereinafter.

There is also mounted on the arm 52 a presser foot I34 which is shown in full lines in Fig. 3 in its operative position.- The presser foot has a leg portion 136 fulcrumed at its upper end at 6 I38 to the arm 52 and has at its lower end a foot M0. The leg and foot are of hollow, U- shaped cross section and large enough to embrace the barrel 52 and nozzle 92. The acting face M2 of the foot is flat and substantially heelshaped, being about the size and shape of the adhesive coated marginal portion of the sock lining. When swung down into operative position from its retracted position (shown in broken lines), the acting face M2 extends beneath the acting face of the nozzle so between the nozzle and the jack. Normally, the presser foot is held retracted at an angular position with respect to the nozzle, and is only moved into a position beneath the nozzle after adhesive has been applied to the sock lining and a tuck has been placed on the adhesive coating surface. The presser foot is then used to press the tuck into engagement with the sock lining and hold it pressed against the jack While the wrapper Edd is pivotally connected to the presser foot and has its opposite end connected to one arm of a bell crank I fulcrumed on a pin I 18 at the under side of the arm 52. Two springs I5l are stretched between a pin fast to the link Hi4 and to the opposite ends of the fulcrum pin I 48 respectively and normally hold the presser foot retracted or in normal position. A chain or other flexible member I 52 is connected to the other arm of the bell crank Hi6 and extends downwardiy over a sprocket or equivalent element i 54 journaled on the pedestal I4 and further down treadle (not shown). By drawing the chain downwardly the bell crank I46 may be swung clockwise and hence through the link it, the

oator are held elevated above the jack of stiff leaf springs I25 (Figs. 1 and 3). of each spring is fastened to the pedestal behind the block IZ'I which in turn is fastened to the pedestal by the set screw 26 and the other end of each spring is engaged beneath one end respectively of the fulcrum pin I .8. The springs are bent over the block 28, passin between the spaced legs of the bifurcated part of the bracket member 32, and are sufficiently stiff to sustain the Weight of the foregoing parts.

In operation, the partial assembly of the upper, sock lining and wrapper is placed over the jack as shown in Fig. 1 and then the acting face of the nozzle s2 is brought into engagement with the exposed surface of the sock lining by depressing the knob lid. Just before the nozzle is brought into firm engagement with the sock lining, the operator has an opportunity to adjust the assembly on the jack so that it will be correctly positioned. By further pressing the knob its, adhesive may be extruded from the nozzle onto the surface of the sock lining along the margin at the heel end thereof, as illustrated in Fig. 8, and if the sock lining is considerably larger in area than the applicator, the latter may be swung transversely in opposite directions to spread the adhesive over the entire marginal portion of the sock lining exclusive of the central portion thereof. Having spread the adhesive, the applicator is raised from the work and an uncoated tuck piece p is laid on the. adhesive coated surface of the sock lining, whereupon the chain I52 is drawn downwardly to swing the presser foot I34 beneath the nozzle into operative position. By continued by a pair One end downward movement of the chain, the arm 52 together with the applicator and presser foot I34 may be brought down so as to engage the acting face N2 of the presser foot with the tuck piece and press it firmly against the sock lining supported by the jack. While thus clamped between the presser foot and jack, the operator grasps the wrapper w and turns it, that is, folds it outwardly and upwardly so that it stands upright from the plane of the sock lining (Fig. 8). The chain I52 is then released and the springs 125 elevate both the nozzle and the presser foot from the jack, whereupon the partial assembly is removed for application of the platform thereto. A quick setting adhesive is preferably employed so that during the interval in which the tuck is held clamped against the sock lining while the upper is being turned, the tuck will be united permanently to the sock lining.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
