Application filed August 5, .1918 SeriaLNo. 248,334.

To all whom it may concern Be itknown that I, BENJAMIN F. l\fAYo, a citizen of the United States, reslding at Salem, in the county of Essex and State of Massachusetts, have invented certaln Improvements in Heeling-Machines, of which the following description,1n CQIIIIGCtIOII WItlI the accompanymg drawings, is a specificae like reference characters on the draw;

tlOn, I

like parts in the several in'gs' indicating figures. I

This invention relates to such machines as those employed for attachlng heels to shoes. More particularly does it concern means for supplying the heels or heel parts, as th top lifts, and carrying them tothe attaching positions. It ELl'SOlS directed to carrying or transferring means for the nails employed in securing the heels and top l fts to the shoes.

Anobject of'the invention 1S tO lIICI'GELSB the automatic effect of machines of the character: above-mentioned, enabling them, withf out undue complication or interference Wltll the control of the machine, toperform op-, erations for which a helper is usually employed.

As a D provided means operating lncidentally to different acts performed upon the work, to

control a device for bringing different work portions into cooperation with each piece of WOIk. This control may be exercised by the main work support, as the jack post on gaging'the lasted shoes, and by operating -mechanism, as that which acts upon the;

workin the nailing operation. When a plurality of kinds ofwork portions, as heels and top lifts, are to be presented to the work, I preferably convey them by holding.

devices which are movable in one direction from their normal positions.- plish this, I have shown power means to" which the holders are temporarily connected by a clutch through movement of the work-support. acts oppositely under the influence of the work-support, so that'the holders are'not only brought into cooperation with the work but are also returned to normal.

To accom- Preferably, the power means in one direction only.

means previously mentioned, to effect the successive delivery of the work portions through movement in one direction. I prefer to controlt'h'e delivery from the con-' tainers by means mounted thereon, and an effective way to actuate at leastone delivery means is by the holder which it supplies. To this end, I have shown a portion of the lift top delivering means in the path of the holders, while, to avoid actuation 1n incorrect timing, the companion deliveringmeans is' clear of the holders.

.A further feature of the invention is found in the control of the nail-transferring mechanism by the conveying mechanism for I In the illustrated embodiment of the invention, the transferring mechanism or loader is moved from its nailreceiving to its nail-delivering position by the conveyng mechanism or swing plate and isreturned by a spring. In the delivery position it is preferably retained during the discharge of thenails by engagement with the'conveying mechanism. This, both for the movement and retention of the trans-- ferring mechanism, may be through the cooperation of a progection 1 and a, wall or flange relatively movable over one another.

Operative engagement between these parts may be effectedby the yieldability of one and released by an opening in the wall through which the projection passes upon-movement ,Other. features wi l, hereinafter appear and, together with those already outlined, are illustrated inwthe accompanying drawings, in -which Figure 1 is a side elevation of a portion of a heel-attaching machine illustrating one form ofmy invention; I

The numeral 10 designates the frame of a heel-attaching machine of the character disclosed in Patent No. 1,157,688 to Glidden, dated October 26, 1915. Operating at the top of the machine is a work-spindle 12, carrying at its lower extremity a cap 14 at the under side of which is mounted an adjusting slide 16 for a jack post 18. In the lower portion of the frame operates a crosshead 20, in which is mounted a nail block 22 having openings to receive drivers carried by a driver plate 24 situated at the upper end of a spindle 26. Movable above the nail block is the conveying or holding mechanism for parts to be applied to the work, these parts in the present instance consistingof heels and top lifts. This conveying mechanism is furnished by a swing plate 28 mounted upon a spindle 3O journaled in vertical bearings at the rear of the cross-head and in an arm 31 depending .from the under side of said cross-head. To the top of the spindle is secured a flanged collar 32 having at its upper side a friction washer 34 of some such material as leather. 'The end of the spindle passes through the collar and is reduced and threaded at 36 to receive an elongated nut, a cylindrical portion 38 of which extends through the opening by which the swing plate is pivoted. Between a head 40 at the top of the nut and the swing plate is a helical compression spring 42' acting to force the plate against the washer 34 and compelits movement with the spindle 30 when this is rotated, though allowing the plate to slip on the spindle when a stop member is interposed in the path of the plate or elements carried therewith. Normally free to turn upon the spindle between the cross-head and the bearing in the arm 31 are upper and lower bevel gears 44 and 46, respectively. These gears are constantly driven in opposite directions, as indicated by the arrows in Fig. 3 ofthe drawings, by a bevel pinion 48 meshing with them and fastened upon a shaft 50 turning in bearings in the cross-head. At the outer extremity of the shaft 50 is a worm wheel 52 having in mesh with it a worm 54 fixed upon a shaft 56 j ournaled in the crosshead and connected to a suitable source of power. Either gear 44 or 46 maybe joined to the spindle 30 by a clutch, here shown as of the jaw type and having a member 58 splined on the spindle. The clutch member and the adjacent faces of the pinions have circular series of projections and depressions adapted to secure the member 58 with either of the pinions for rotation. The member 58 is provided with an annular groove, into which extends the points of projections 60 from opposite sides of the yoke-shaped end of a lever 62 fulcrumed at 64 upon the cross-head. Pivoted at 66 to the lever 62 is a bell-crank. lever 68 fulcrumed at 70 on the frame 10. An upwardly extending arin 72 of the lever 68 is curved forwardly toward the work spindle.

12, and has contacting with it the edge of a cam arm 74 upon a lever 7 6 fulcrumed at 7 8 on the cap 14 of the work-spindle. The opposite arm of the lever 76 contacts with a projection 80 from the ack post 18, the relation being such that, as the. jack post is moved inwardly, the lever 76 shifts the bell-crank lever 68 to raise the clutch member 58 into engagement with the upper gear 44, thus turning the spindle 30 and swing plate in an anti-clockwise direction as viewed from above. A. spring 81 maintains contact between the levers 68 and 7 6 and projection 80, so that, upon opposite movement of the jack post. the bell-crank lever is swung inwardly to shift the clutch member into engagement with the lower bevel gear and reverse the movement of the spindle and swing plate.

Carried uponthe upper surface of the swing plate are heel and top lift holders having breast gages 82 and 84, respectively, adj ustably clamped in position by screws 86 and 88 passing through slots in the side arms-of the gages. The heads of the screws are located in depressions extending along the slots, so that the tops of the screws are substantially flush-with the upper surfaces of the gages. Fork members 90 and 92 of the holders cooperate with the breast gages, their shanks moving in ways 94 and being retained in place by screws 96 passing through slots in the shanks. The forks are automatically moved toward and from the breast gages in the oscillation ofthe swing plate. For this purpose, a bell-crank lever 98 is fulcrumed at 100 on the swing plate and has a rounded end entering between lugs 102, 102 proj ecting from one side ofthe shank of fork 92. Carried by the cross-head at the left-hand edge of the swing plate is a pin 104, in the direction of which the lever 98 is normally urged by a spring 106, this also tending to move the fOIK toward the breast gage. At the inner side of the shank of the fork 92 is an arm 108 contacting with an arm 110 upon the shank of the fork 90. These arms are held in contact and the fork 90 toward the breast gage by a spring 112. When the swing plate is at its initial or exof contact, the springs draw the forks to-' ward the breast gages to clamp the heels and top lifts in the holders for presentation to the work and nailing mechanism.

Situated side by sideat the left of the nail block, alined with the heel and top lift holders when these are in their initial position, are heel and top. lift containers or' magazines 114, 116, respectively. These containers are in the form of tubes, of a crosssectioncorresponding to the parts they are to contain, and are supported by arms 118,-

118 fixed to. the frame 10. Mounted on the container 114 are supporting means, shown as comprising spindles 120, 120 rotatable in bearings secured to the containerwall. At

the inner end of each spindle is a lever 122, the lower end of which is curved at 124 beneath the end of the container tube, giving a horizontal supporting surface for the bottom heel of the stack. The upper extremity of each lever at 126 is provided with a vertical yieldable engaging surfacewhich may be furnished by a spring 127 extending into,

an opening in the side of the container tube for contact with the second heel of the stack. Therelation between the ends 124 and 126 is such that, when the former. is beneath the container supporting the heels therein, the end 126 is withdrawn from its opening, leaving the heel opposite and those above free to move downwardly, but, as the lower end of the lever is swung to one side and just be fore the bottom heel drops, the succeeding heel is engaged by the springs 127, supporting the stack until the levers are moved in the opposite directions. Fixed to the for ward ends of the spindles 120 are arms 128 and 130 joined to one another by a slot and pin connection 132. The arm 130 is a portion of a bell-crank lever, the other arm 134 of which extends downwardly and liesin the path of a projection 136 rising from the upper surface of the swing plate. In the clock; wise movement of'the swing plate, the pro 136 by its contact with the other side of the arm 134 restores the levers 122 to their. normal positions.

At the bottom of the conta ner 116 1s a bracket 138 supporting a horizontal slotted guide arm140. In this guideway moves a top'life supporting slide 142., whichis drawn normally beneath the container by a spring 144, thus supportingthe stack of top lifts. The clockwise movementof the swing plate carries the top lift breast gage 84 beneath the heelcontainer without interference with its elements, which are out of the line of travel, but when the top lift container is reached, the securing arm of the gage'strikes the forward end of the slide 142, forcing it back in the guideway, as is best seen in Fig. 7, and permitting the lower top lift to drop into its holder upon the swing'plate. Upon reverse movement the arm of the breast gage supports the succeeding top lift until the slide can be drawn by its spring beneath it to sustain the remainder of the stack. It should be observed that in this delivery position for both the heels and top lifts, the forks are drawn back by the mechanism already described, so the work portions may be freely introduced. to the holders. I The clockwise or restoring movement of the swing plate is unimpeded between its extreme positions, these being indicated in full and dotted lines at the left and right, respectively, of Fig. 2. In the opposite or heel and top lift conveying movement of the swing plate, a latch 146pivoted upon an arm 148 fixed to the lower extremity of the spindle30 and normally raised by a spring 150 seated in a chamber depending from the arm, comes-in contact with a stop projection 152 from the. arm 31. movement of the swing plate under the influence of the spindle to stop when the heel holder is alined with the nail block, the frictional connection between the plate and spindle slipping to permit this. When the operator bringsthe nailing mechanism into action to drive the nails through the heel, a

' the top lift holder arrives in position over the nail block, at which timethe swing plate is at its extreme limit of movement in this direction, and is stopped by contact with a portion of the cross-head. Pivoted at 156 on the cross head at the opposite side of the nail block from the con-1 tainers, isnail-tra-nsferring or loading mechanism, the oscillating arm 158 of which carries a loader block 160 perforated to receive nails from the usual distributing mechanism (not shown). A spring 162tends to turn the loader arm toward the right into contact with a stop member 164. The customary loader gate 166 is pivoted at 168 on theunder side of the loader arm, serving to sustain the nails in the perforations of the loader block after they have been supplied by the distributing mechanism and until This causes the they are transferred to the nail block. This gate is latched in its nail-supporting position by the engagement of an opening or depression in it with a projection 170 from the loader arm. lVhen the gate is released from the latch, a spring 172 carries it from be neath the loader block to permit the downward passage of the nails. It may be reset by contact with the stop 164 when the loader arm is moved against said step by the spring 162. The loader arm is carried into delivery position with its perforations alined with those of the nail block by engagement between a flange 17d, shown as depending from the inner edge of the loader arm, and a projection 17 6 carried by the swing plate. This projection is movable in a socket 178, being held upwardly'by a spring 180 seated in the socket beneath the projection. On its side toward the flange 17% the projection is inclined so that, upon contact between the projection and flange in the anti-clockwise or conveying movement of the swing plate, the projection may move across the flange by its depression in the socket. Then, when the swing plate is turned in the opposite direction,the projection carries the loader arm with it, sliding along the inner face of the flange 1%, being directed across an opening 182 in the flange by a gate 184:. This gate is pivoted onthe side of the opening toward the axis of rotation of the loader arm and held by a spring 188 in contact with the flange at the outer side of the opening. The

' swing plate projection 17 6 rides over the end of this gate, and in so doing the edge of its socket contacts with a lug 190 on the loader gate, disengaging the latter from the projection 170 to deliver the nails. As the projection 1'76 strikes the flange 17% after slipping from the point of the member 184, it jars the loader block, facilitating the passage of the nails therefrom. This occurs at the end of the clockwise movement of the swing plate and loader arm. Upon anticlockwise rotation of the swing plate and the travel of the projection in the opposite direction or toward the axis of the loader arm, it contacts with an inclined face 192 upon the end of the gate, raising it and allowing the projection to pass through the opening 182-. Theloader arm is thus released and is turned by its spring against the stop 16 l,resetting the loader gate. 7

To summarize the operation of the machine, the nailing of a heel and top lift upon a shoe may be considered to have just been completed, the swing plate and loader arm occupying the positions indicated in dotted lines in Fig. 2. At vthis time, the swing plate projection 176 will have crossed the loader arm flange, in a position to move along its inner side upon the clockwise rotation of the swing plate. The operator now swings out the jack post to remove the shoe with the attached heel. As an incident to this act, the connecting lever system brings the clutch member into engagement with the bevel gear 4:6, rotating the swing plate to the left. The projection 17 6, sliding along the flange, carries the loader arm with it, and,

when the loader block reaches the position in which its openings are alined with those of the nail block, the socket of the projection frees the loader gate from its latch 170 by contact with the lug 190, delivering the nails to the block where they are supported upon the drivers. At the same time, the breast gage Se and the projection 136 have actuated the delivery means ofthe top lift and heel containers, respectively, to supply these parts to their respective holders, the forks of which are drawn back to receive them. At this time the parts are as illustrated in full lines (Fig. 2). The operator new places the lasted shoe to be heeled upon the jack post spindle and swings it in until the heel seat is above the nail block positioned by the band clamp (not illustrated). In so doshifts the clutch member into engagement with the bevel gear 4%, so that the swing plate is rotated in an anticlockwise direction until stopped by the engagement of the latch 146 with the projection During the first portion of the movement of the swing plate, the'projection 1'76 travels along the loader arm flange toward the gate 18 1, raising it so that the projection may pass through the opening 182 to free the loader mechanism for its return by its spring to the nail-receiving position. Upon actuating the treadle, the heel nailin operation is performed, and the nailing mechanism in rising trips the latch 146, freeing the swing plate. The friction, which has been slipping during nailing, thereupon carries on the swing plate until the top'lift is positioned beneath the heel from which the points of the nails are projecting. The machine is now operated to spank on the top lift and, the parts being in the positions shown in dotted lines in Fig. 2, the operations upon another shoe may be performed.

It is to be noted that, after the containers have been supplied with heels and top lifts, the operation of my improved machine is entirely automatic, save for the introduction and removal of the shoes to be heeled, and that, because of the location of the containers at one side of the work and opposite the nailtransferring mechanism, the work-engaging elements are left free for manipulation by the operator, and the conveyance of heel parts and nails is by an organization simply and effectively controlled.
