18 Claims.

My invention relates to apparatus by which glue, or other adhesive, may be applied to workpieces, it being especially adapted for use'in con-.

nection with the gluing of heel-portions, as heelplate, the latter being perforated. The pot, to-

bases or lifts, to prepare them for nailing to shoes. Herein it is disclosed as an attachment for the heeling machine which is the subject of an application for Letters Patent of the United States, filed in the names of- John F. Standish and Lester S Macdonald on May 28, 1937 and bearing the Serial No. 145,320.

In gluing attachments for heelers, there is commonly provided a roll rotatable in a glue-receptacle and turned sumciently during each operating cycle of the associated machine to present a freshly coated surface to which the operator may apply the cup of the next heel to be attached. As the glue is lowered in the receptacle by its use, the roll brings up varying quantities. When the receptacle is first filled, the application to the heels may be excessive, but, as the work proceeds and the charge upon the roll diminishes,the heels may receive too little glue. It is an object of this invention to present for application, in a manner convenient for the operator, substantially unvarying quantities of an adhesive regardless of its depth in the receptacle. This object I attain by combining with the receptacle an adhesivesupplying member, which may consist of a plate, and an applying member, preferably a roll, the supplying member being arranged to lift the adhesive from that in the receptacle, while the applying member moves toward and from the receptacle to take it from the supplying member. By this arrangement, as the members travel along each other, there may be produced a delivery to the applying member, which, within working limits, is independent of the depth of the adhesive in the receptacle and which is distributed uniformly upon said applying member. To avoid an unduly heavy coating upon the applying member, the supplying member is preferably perforated, so, upon engagement between the two members, the excess of the adhesive may escape under the pressure from the path of the applying member. For the gluing of the cups of heels, the applying member preferably has a transverse contour approximating that of the heel-cups and the contacting surface of the supplying member is best 'complementally formed. As herein disclosed, the apparatus has a glue-pot with which are associated slides carrying the supplying membr and the applying member and oppositelyreciprocated to establish contact between said members. This movement may be effected by reciprocating one of the slides and connecting the other to it by racks and an intermediate pinion. The applying member is preferably in the form of a rotatable, convex roll and the supplying-member a concave gether with the plate and roll or other glue-supplying and -applying members, are shown as covered by sections hinged at opposite sides of the pot and meeting above it. Such heel-attaching machines as that previously referred to have elements operating through definite cycles successively controlled by the operator, and, to insure the correct presentation of the applying member with a fresh coat ofthe adhesive ready to receive contact of the heel to be attached, I so reciprocate the members of the applying apparatus from an element of the machine, that their movement stops at the end of an operating cycle with the applying member raised from its receptacle and the supplying member lowered therein.

The accompanying drawings illustrate a particular embodiment of the invention,

As fully set forth in the previously-mentioned application, a. heeling machine, to which this applying apparatus maybe attached, has a frame l (Fig. l) carrying nailing mechanism l2 and an opposed heel-engagin Pressure-head l4 movable toward and from the nailing mechanism in guides l6. Successive loads of nails are transferred by a reciprocatory loader-block ill to the nailing mechanism, for insertion in the work, from a foot-plate 20 through which they are delivered. The actuating mechanism for the loader-block includes a spindle 22, oscillating in the frame under the control of a hand-lever 23 once during each operating cycle of the machine.

It is usually desired to apply to each heel, before it is nailed, a coating of an adhesive over the cup. My improved applying apparatus for this purpose is shown at A. Secured to one of the guides I6 is a bracket consisting of a. depending bar 24 carrying at its lower extremity a mounting plate 26. Pivoted at opposite sides of the lower portion of the plate to swing horizontally are bolts 28, 28,'arranged to enter slots in spaced lugs 30, 30 projecting from the bottom of a receptacle 32 for glue or other adhesive. This glue-pot has a cover preferably comprising opposite sections 34, 84, each of which is pivoted upon a lug 38 at one side of the top of the plate 26. The cover-sections meet at the center to furnish a complete closure for the pot and rise considerably above it to give a space, the purpose of which will later appear. By loosening thumb-nuts upon the bolts 28, 28 and swinging aside said bolts, the pot may be removed readily for cleaning, leaving the cover undisturbed. Guided in spaced vertical ways 38, 38 in the plate 26 are slides 40, 42'having their opposite ends bent inwardly and downwardly toward the interior of the pot. Projecting horizontally from the down-turned end of the arm 40 is a spindle 44, which is normally situated above the pot. About the spindle is freely rotatable an applying roll 46, best of some such yieldable material as soft rubber, and with its convex periphery approximating in contour the transverse contour of the heel-cups which are to be coated. By'having the form of the roll-surface a mean between the extremes of the heel-cups, the yield of the roll will allow it to conform properly to the entire range of work. Fixed to the overhanging end of the slide 42 is a horizontal arm 48 projecting from a plate 50, which in the lower position of the slide preferably reaches from a point somewhat above the top of the pot nearly to the bottom thereof. Horizontally the plate is concave, its contour being substantially complemental to that of the roll. Itis provided with numerous perforations 52, through which glue may pass, and at its upper extremity 54 is flared out,- wardly to permit the reception of the roll by the concavity without interference. The v adjacent edges of the slides 40 and 42 carry rack-teeth 56 and these are connected by a pinion 58, the outwardly projecting spindle of which is free to rotate in a plate 62 attached to the bracket-plate 28 between the slides.

One of the slides, as that carrying the plate 50, is extended downwardly at 64 below the plate 26. At its lower end, it is joined by a link 66 to a bellcrank-lever 68 fulcrumed upon the frame. The lever is connected by link 10 to an arm I2 fast upon the end of the spindle 22 outside the frame. Normally, or when the heeling machine is at rest with the loader-block I 8 in its rearward position beneath the foot-plate 20, the roll 46 is raised to the extreme of its upward travel above the pot 32, and the plate 50 is correspondingly lowered, a considerable portion being immersed in the glue, which is indicated at G in Fig. 2. The operator depresses the lever 23, causing oscillation of the spindle 22. As a result of this, the loaderblock 18 containing a load of nails advances and delivers them to the nailing mechanism l2. By the connection between the spindle and the depending portion 84 of the slide 42, this raises said slide and through the pinion 58 simultaneously lowers the slide 40. The roll 46 is thereby carried toward and into the pct 32 above the glue-level, while the plate 50 rises bringing up a coating of glue upon its concave face. This relation is indicated in dotted lines in Fig. 2. In these opposite movements of the roll and plate, they travel relatively in contact with each other, transferring glue from the plate tothe entire periphery of the roll. Any excess of the adhesive, which with an imperforate plate might be pushed before the roll and gather in a ridge upon its surface, is permitted to escape through the perforations 52. The coating upon the roll will be smoothed upon it by the travel along the plate and when the nail-supplying mechanism stops with the loaderblock again beneath the foot-plate, the roll will be again in the position illustrated in 1'18. 1 and carrying a substantial uniform coating of the adhesive about its entire periphery. It is so located above the pot, that, with the cover-sections opened (Fig. 1), it will be convenient for the operator to draw the cup of the heel over it to receive a coating. By the simultaneous oppomte reciprocation of the applying and supplying elements, the extent of movement and the time required to deliver to the roll its coating of adhesive are reduced, and, while the applying member is raised to give the operator ready access to it, the

supplying member is lowered so a considerable portion is within the glue. This, together with thedistribution of the adhesive by the rolling of the applying member over the perforated plate, gives a substantially uniform coating in spite of lowering of the adhesive level during the use of the apparatus. The heel thus coated is placed upon the heel-seat of a shoe at the nailing mechanism l2, the head I 4 lowered to apply pressure to the work and the machine started for a single operating cycle, during which the nails are driven into the heel. Thus, successive nail-delivering,

heel-cup-gluing and heel-nailing operations are performed. When the apparatus is not in use, the pct 32, together with the glue-applying and -supplying elements, may be completely enclosed by swinging up the cover- sections 34, 34. This reduces evaporation from and spoiling of the adhesive. The pot is removed for cleaning by simply releasing the bolts 28, all the other elements of the apparatus remaining in place upon the bracket.
