"This invention relates to'apparatus by which reinforcing -means may be supplied to a ma- "chine-by "which they are to be attached. Especially, the 'invention is concerned with the deliv- 'er-y to heel-attaching machines of the plates v vention-is tosupply such reinforcements of vary- :ingsizesaccurately, as to theirpositions with :respect to the heel-portion to which they are lto be'nailedandin a manner which will mini- :mize effort onthepart of the operator.

To-attainthis'object, I combine with a heelh'older, as the customary'heel-ringmovable into and out of .co-operation with nailing mechanism, means-for supplying reinforcements to saidholder,-'through=which reinforcements nails are drivenrby ;the nailing mechanism into heels con- :tained in the :holder. The reinforcement may lthus lbe positioned in the holder when this is .s'eparated from the'nailing-mechanism, and said .holder .is then returned to receive a heel for attachment simultaneously with the reinforce- :ment. Preferably, the reinforcements are contained-sin one -or more magazines from which .they are ejected successively into the'holder. To reduce the burden upon the operator, the dellveryrofithereinforcements is made dependent .uponsan'other act'which he must perform, as the transfer of nails to the nailing mechanism. There .isrhereinzdisclosed amovable heel-ring and an iejectonmovableiinto a magazine-tube, there being connections to a mechanism, as that for loading snails into the'die-block of the heel-attaching-machine, for :controlling the movement ofebothsthe'iheel-ring and'the ejector. Themovemento'f the ejector is bestefiected by a spring, -Which=is=..tensioned as the ring is carried into its receiving position, and then permitted to act under tna-control of a cam actuated from the loadingxmechanism. To enable the operator to .chooseiconvenientlyany one of a number of sizes .of-reinforcements for-attachment, as the work in lhand :may :demand, a plurality of magazines may bezprovided, whichzmay be brought selectively. into 1 deliveringrelation to the heel-holder. In the illustrated embodiment of the invention,

these magazines :are :mounted upon a rotatable turret. :A chosen :magazine-may be located in "its deliveringposition'with respect to the holder, by means whi'ch'it carries and which may consisto'f a rollsupporting it as theturret rotates and which, b-ymovement'of the magazine upon the'turret, enters a depression in the surface uponwhich ittravels toproduce the locating effect. "Means, movable by'the operaton'maybe utilized 'to"free"the'turret from the locating means, :as by the'elevation of a magazine to remove its roll fromthe-depression. By means variable in positi'onin each'magazine, thismay be adapted for 'holding reinforcements of different sizes. 'This meansis herein shown as a'postrising through the magazine and a sidewall, both the post and wall being adjustable. 'To guard against the ejected reinforcement being thrown beyond the opening-intheholderwhich it is to enter, means in'the'formofa'wall is provide-d'which'will de- "flect the "reinforcement into the *holder. This wall is 'preferablya'djustable to cause it to act efi-ectivelyup0n the various sizes of reinforcements. g 1

One of *the many forms which my invention 'may'assume is illustrated in the accompanying drawings, in which:

Fig. 1 is a broken front elevation of the apparatus'mounted upon a heel-attaching machine;

:Fig. 2, a top plan. view of the apparatus and more closelyassoci'ated portions of the heeling machine; and

-Fig. 3, an-enlarged vertical section on the line IIIIII"0fFig. 2.

"At 1 ll'appears'a'portion of "the'frame of aheeling machine, such, for example, as is disclosed in Letters Patent of the United States No. "1j157,688,"Glidden, October 26, 1915, this being adapted for the attachment of' a heel to asho'e 'bytheinsertion of nails through the tread-end of-said heeland-the heel-+seat of the'shoe,-Whe're they are-clinched upon "the insole. 'The shoe is presented-upon a ack 12 to be pressed against 'aheel supported-overa die-block [4. Through passages in this die nail-drivers I6 "reciprocate. The *present invention is preferably "combined with aheel-hol'der, such as that of Letters Patent of'the'United-States No. 1,365,802, Standish, January 18, 1921, =which'has a ring or plate [8 mounted in a 'frame 20 and with an ppening 'z z 'formed to receive a'heel, and, in the present instance, -a reinforcing plate, with its treadsurface down and positioned over the'die block for nailing. The reinforcing plates are shown at P-in Fig. 2, eachwbeing of metal of generally horseshoe-shape and-provided with openings'p, through which the attaching :nails are to be the die, to respectively receive nails in its block 29 and deliver them for the attachment of the heel-portions. Interchangeable rings I8 are provided, one for each of the various sizes of reinforcements. These rings are so arranged in the frame 26 that the rear extremities of all sizes of the reinforcements and their rear openings are respectively at the same points in their receiving and nailing positions.

Considering the features peculiar to the present invention and especially the means for supplying reinforcing plates to the ring I8, there is secured to the left of the machine-frame III, at about the level of the die-block I4, a bracket 30. Rising from the bracket is a vertical spindle 32,

surrounded at the bottom by a bearing or spacing'ring 34. Upon this ring rests the rotatable spider36 of a turret T. At the periphery of this spider is a series of vertical ways 38, shown as six' in number, equally spaced from one another circumferentially (Fig. 2) and each divided into two vertically separated sections (Fig. 1). These ways receive correspondingly separated projections 40 from a bar 4I, to which is attached at 42 the inner side of a vertically extending magazine-tube 44, the horizontal .con-

tour of which may approximate that of the peripheries of the reinforcements which they are to contain. Each tube is partially closed at the bottom by a plate 46, upon'which rests a stack of the reinforcements, upwardly extending lugs 48, at the ends of each of the spaced arms, being secured to the tube and having a crossbar 50 connecting them. At the front of the plate 46 is an opening through which the bottom reinforcement of the stackmay fall when it is pushed forward. I

It is preferable to arrange each magazine-tube to hold a plurality of sizes of reinforcements. To permit this, and considering one only of the tubes, there rises from the bottom a post or cating member L. This may be formed of a strip of sheet-metal, having at its lower-extremity parallel arms 52 and 54, respectively below and above the bar 50. From the lower arm, an upright56 extends substantially to the top of the tube in a direction parallel to the rear curved wall. The member is then bent downwardly and outwardly at 58, terminating in the arm 54. This arm is slotted longitudinally and through the slot passesa' screw 60 threaded into the arm 52. The screw clamps'the post to the bar, allowing the former to be adjusted so the upright 56, for engagement with theinside of the stack of reinforcements P, will hold said reinforcements with their opposite or outer edges in close proximity to the wall of the tube. This places these edges all in the same vertical line, and the mounting of the tubes upon theirprojections 40 is such, that the rear walls of all the tubes are at the same distance from the radii of the spider which pass through the centers of the projections. This prepares for the ejection of the reinforcements from all the magazines into opening 22 of the plate IB for anysize of reinforcement, when this is inreceiving position, by a delivery member movable through an unvarying distance. To locate symmetrically reinforcements varying in width laterally of the tubes, there is in the lower portion of each of said tubes and at each side thereof, an adjustable inner wall 62 of sheetmetal. This may occupy positions close to the tube-Wall for the wider reinforcements; or may be'caused to converge inwardly and-downwardly to centralize narrow reinforcements. At their tops, the walls 62 are secured pivotally by screws 64 passing through their out-turned flanges 66 and flanges 66 of the'tubes. At the bottom, the wall-flanges are widened and provided with arcuate slots I0, through which are screws 12 threaded into the tube-flanges. The walls may, therefore, be bent in and out and secured by the screws 12. The effect of the positioning means upon the reinforcements will be understood upon the comparison of the different magazine-tubes in Fig. 2.

Any one of the tubes 44 maybe brought selectively into delivering position by rotation of the turret T by the operator. That tube at the extreme right of the turret in Fig. 2 is so situated.

In the rotation of the turret, each tube is supported as it travels by a roll 16, rotatable about a horizontal axis at the bottom of the corresponding bar 4i and bearing upon a horizontal surface I8 of the bracket 30., When the magazine-tube which the operator has chosen reaches the delivering position, the roll and the adjacent end of its bar enter a depression 80 formed in the surface 78, the projections 40 slidingin the ways 38. The turret is thereby held-against rotation. To further and more exactly locate the selected tube by means carried directly upon it, its plate 455 has depending from it a projection 82, which, as the tube falls, is received by an opening 84 in the horizontal surface of the bracket 30. To free the positioned tube, so that the turret may be turned to present another for delivery, there is arranged to reciprocate vertically in the bracket a slide 86, having an arm786 extending-beneath theroll. Pivoted below the bracket is a hand.- lever 80, the inner end of which engages the lower extremity of the slide. Upon actuation of the lever, the slide, roll, bar and tube are raised, with said roll above the surface 18. Thereupon, the operator may turn the turret to its new position, the roll travelling from the upper surface of the arm 83 on to and over the bracket-surface. In this elevation of the tube, it is brought to such a level that the lower portion Will travel clear of the ways 94 of a reinforcement-delivering slide 96, arranged to reciprocate horizontally'upon the bracket 30.

When the nail-delivering movement of the loader-arm 28 effects the advance of the heel-ring I6 to its reinforcement-receiving position, it also causes the slide .96 to eject a reinforcement P from the magazine-tube which is in delivering position. In this feeding action, the forward extremity of the slide enters-openings 98, 08 in the vertical wall of the tube just above the bottomplate 46, there being a division at I00 in the slide to permit it to pass the post L. A link I02, adjustably connected to .the slide '96 in a slot I04, is joined to an arm I06 pivoted at I08 uponthe bracket 30. A torsion-spring I I0, surrounding the arm-pivot, urges a roll IIZ rotatable upon the arm against a cam-surface, I I4 upon a lever H6, fulcrumed at I I8 adjacent to the pivot I08. .A link I26 unites the cam-lever to the loader-arm. As said loader-arm, carries in the openings of its block 29 a load of nails tothe die I4, the link 26 turned clockwise (Fig. 2) :until the load is deposited $111 .the die-block-passages. 'movement of the arm, the link 26 carries the .heel-ringla from above the die-block to beneath .the'positioned magazine-tube and there temporrarily holds it. As the link 26 acts, the link I20 'advances the: frame .20 of .the ring '18 .aso that, "whentheiload of .nailsis deposited in the die- ;passages, thering-opening22 is beneath theselectedmagazine-tube. During the travel of the ring, a portion a of :thecam-surface H4, concentric- -with the axis of its fulcrum H8, is moving alongtheroll-l I 2, so the arm I06 and the slide -f96:rema'n'stati0nary. But when the ringis ready for'ithe reception of its reinforcement, the roll isifreed by-a portion of the cam-surface at b having an abruptly decreasing radius. The spring 1| l ilz'now acts to urgethe slide through the openings- 98. intothe .magazine-tube, where it engages theireinforcement at the bottom of the stack and :forcesthis forward beneath the'arm 52 of the post L to descend through the opening in the .plate dfi into the: opening 22 of the ring. To presvent=the ejecting force from throwing-the reinforcement beyond the ring-opening, a stop or deflecting member is located in the path of said reinforcement above the forward edge of the opening. IItmayconsist of a wall I22-(Fig. 3), :inclineddownwardly and outwardly beneath the arm' 52 of the'post-L, and then bent outwardly, upwardly and inwarolly where it is adjustab ly secured by *sloteand-screw connections I24 (Fig. .2) tothe bar of the'magazine-tube. Its position, toward and-from the delivery-opening from the tube at the front of the plate 46, may be varied to cause it to act most effectively for reinforcements of different dimensions and weights. Upon entering the ring-opening 22, the reinforcement rests upon ahorizontal plate I26, which is secured to the die-block-support 25. The upper surface of thisplate is flush with the upper face of the die-block. When the loader-arm is swung back to receive the succeeding load of nailsin the block 29, the ring l8 will be restored to its normal relation over the die-block. In its travel, the reinforcement contained in the ring-opening slides In using my improved supplying apparatus, thev operator places in the frame 20 a ring vl8 having an opening 22, of such contour-that there will fit within its lower portion the reinforcement P to be attached, while in the upper portion will fit a heel orheel-lift to, which the attachment is to be made. The two heel elements will be in a'definite transverse relation to each other, so if the upper is a rubber lift in which are washers, the openings of said washers will register with the openings 10 of the reinforcement. The magazine-tubes 44 of the turret T may contain all the sizes of reinforcements which the operator will be called upon to use during his days work. Each tube will have its post L and walls 62 adjusted to hold the stack in proper position. The nailing design of the die-block l4 and of the loader-block 29 will, of course, also correspond'to that of the openings p. If the desired size of reinforcement is not contained in the magazine which is located in delivering position by its roll 16 and projection 82, the operator will depress the lever to free the magazine and will then rotate the turret, the rolls of all the magazines travelling over the bracket-surface 18. The slide-arm 88, which effects the-release of the magazine, will be kept raised until-the-one chosenarrives in position,

whereupon it is released andthe roll and projection of such magazine will descend and lock it positively'in the correct relation. The arm 28, .withaloadof 'nails'inits block 29, may now be magazine-openings fii. bottom reinforcement P in the stack advances openingi22'upon the plate i 25. the-reinforcement to be thrown beyond the opening 22-is prevented by its engagement with the =Wa11' i -22, which deflects it downwardly into the *rnent'to the shoe. tinue until another size of reinforcement is required-when the turret is shifted, as already de- During this isoscillatingthe lever l [6, so its concentric camsurface a moves along the roll H2, holding the ejecting slide 96 against movement by its ten- --sioned-spring I it). But when the surface b of the cam'reaches the roll, as the ring I8 attains its receiving r-relation, the roll is released and the springacts to advance the slide quickly into the The slide, striking the this from the plate 46, so it falls through the opening in said plate and is deposited in the ring- Any tendency of ring. If, during the ejection, the reinforcement resists movement, as because of projecting burrs, the spring-actuated slide will stop without injury to the parts. Upon restoration of the loader-arm 228: to its normal position, the cam-surface b withdraws the slide 96 from the magazine and retensions the spring H8. The ring H8 containing the *reinforcement returns over the die it, said reinforcement sliding'first upon the plate I 26 and then upon theupper face of the die. With the loadereblock back in its nail-receiving position at the-foot-plate of the distributor, the openings p of the reinforcement are in registration with the die block-passages. The operator, thereupon, applies to the ring-opening 22 a heel or heelportion H with its tread-end resting upon the reinforcement, lowers the jack I 2 upon which a shoe-has been placed until the heel-seat of said shoe is upon the heel and starts the power-oper- 'ation of theattaching machine.
