Patented Oct. 29, 1929 UNITED STATES PATENT QFFICE JOSEPH H. POPE, OF HAMILTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- CHINERY CORPGRATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY HEEL-ATTACHING MACHINE Application filed September to effect the ustmcnt by means of a screwconncction to the member to be moved, but where the range is great, this is slow and troublesome. As a feature of the invention, I facilitate the change by the provision of means for producing both a rapid and gradual adjustment, the former giving an approximate setting of the member,and the latter a more exact positioning, or serving alone when the alteration to be made is slight.

Another feature of the invention involves so positioning the various parts of a holder for heel-portions with reference to each other and to the shoe to which the portions are to be attached that such portions are etl'ectively grasped and accurately presented.

There may be provided adjustments of the holding mechanism or swing-plate as a whole, of the clamping members or j aws, and of the gage or back-stop which co-operates with said clamping members.

A further feature concerns a connection between the clamping members or jaws which will insure their free movement. This connection, which includes a spring acting to force the clan'iping members toward each other, has a movementof self-adjustment along the jaws while engagement with opposite edges thereof is maintained. It preferably comprises a retaining member or casing movable upon the jaws, and a spring carried by the casing and contacting with said.

jaws. There may he means associated with the casing to vary the normal separation of the jaws.

Vv'hen oscillatory clamping jaws are con- 5, 1923. Serial No. 661,072.

nected to move together, as by intermeshing teeth, these teeth may wear, so they do not properly engage. As still another feature of the invention, I compensate for this wear by a variation in the relation between the mountings of the jaws, as by pivoting them upon studs which have eccentric portions.

Such an adjustment as that of the jawpivots just mentioned, when made in connection with a bodily movement of the jaws upon a pivoted carrier through a definite angle, tends to disturb the extent of angular movement, and, to maintain the correct angular relation, I provide, as a feature of the invention, for adjustment of the movement of the carrier, the adjusting means being preferably readily accessible. As illustrated, this adjustment is effected by screws threaded through a member upon the upper extremity of the spindle, by which the carrier is pivoted.

An additional feature of the invention has to do with the control by the holding mechanism of the nail-transferring or loading mechanism. To prevent the deli very of nails by the loading mechanism when a top-lift is being presented by the holding mechanism, the latter mechanism actuates a locking member for the former. This operation, with an oscillatory holder of the character herein described, I prefer to accomplish by means of a yieldable arm, oscillating with the holder and its spanker-plate and engaging a latch, to move it to holder-locking position.

The accompanying drawings illustrate aparticular embodiment of my invention,

At 10 appears a portion of the frame of a heel-attaching machine of the type disclosed in the patent in my name numbered 4456,88?) and dated Feb. 2 1:, 1891. This frame su ports the holder 12 for a die-block 14:, and in it reciprocatcs the sine rods lo. ll; connected by a top girt 18, upon which are carried drivers 20, said die-block and drivers co-opcrating to furnish the nail-driving mechanism. Nails may be delivered to the dieblock-openings by a loader-block 22 carried by the extremity of a loader-arm 24 arranged to swing about one of the side rods 16. The movement of this loader-block is between a receiving position, as appears in Fig. 1 of the drawings, in which its openings are supplied with nails, and a nail-delivering position over the dieblocl in which said nails are deposited in the diebloclvopenings.

Secured at the back of the dio-block-holdor is a supporting bar or elongated bracket 26, having near its enter a horizontal rearward extension 28, passing vertically through which is a longitudinal slot 30. ln this bi'acket entension, beneath the slot, are ways 32 to receive a slide 34, from which rises a tubular post 36 movable along the slot 30. ltotatable in the post is a spindle 38 having fixed at its lower extremity a swing-plate or carrier d0 for a heel-holding device A. and a top-lift-holding devi e B. The swingplate is rotatable by means of a handle 41-2 depending from it, to bring either the heelholder or the top-lift-holder into a position in which the heelportion carried is presented beneath the dieblock for the nailing operation, it being at the same time positioned above the heel-seat of a shoe S supported upon a jaclt 41:41. The axes of the holding do vices A and. B are separated by 90 degrees, and the angular movements of the swingplate to its opposite extremes, in which the respective heel-portions are brought into the attaching position, are determined by screws 46, ll; threaded through a block 4-8 lreyed near the upper extremity of the spindle A. nut 50 upon the threaded upper extremity of the spindle holds the block against upward movement, and by the contact of the latter with the top of the post 36, prevents the downward displacement of the swii plate. The ends of the screws 46 contact with opposite surfaces upon alls 52, 52 rising from the bracket 26 at each side of the slot 30. The swing-plate is spaced from the bottom of the bracket 26, and within this space are clamping aws 54, 54 pivoted 56, 56 upon the upper face of the swing-plate. The outer extremities of the jaws have roughened surfaces 58 adapted to grasp the periphery of a heel near the breast. The aws are connected to move together simultaneously in opposite directions by intermeshing portions or teeth 60, (30. The engaging surfaces 58 are forced yieldably toward each other, to bring the jaws into such relation that they will grasp the smallest heel which is to be attached, by a spring 62, the ends of which contact with the opposite inner edges of the aws near their inner extremities. This spring is contained in a tubular casing or retaining member (34 slotted at 66, 66 sothe ends of the jaws may pass through the casing to receive the pressure of the spring. At the outer edges of the aws, where the casing co-operates with them, are depressions 68, 68 retaining such casing against displacement to any great extent in either direction, yet permitting a free movement of self-adjustment longitudinally of the aws. By this means, binding or cramping of the spring and its retaining member is prevented, this being especially useful when the oscillation of the jaws is CODSlClQIal'JlQ. One extremity of the casing is threaded to receive a nut 70. This, contacting with the inner wall of the depression 68 at this side, may be adjusted in either direction to vary the normal extent of separation between the heel-engaging surfaces 58. It serves to adapt the space between the jaws to the heel of minimum width. which is to be operated upon.

The correct meshing of the projections 60 may be interfered with by their wear, and to take up the lost motion, the pivots 56 are shown as in the form of studs fixed on the swing-plate by nuts 72 (Fig. 9) threaded upon their lower ends. The heads 74 of the studs, about which the clamping jaws turn, are eccentric to the axes of the studs proper. Consequently, the studs may be turned and fixed by the nuts in different positions, thus varying the pivotal points of the aws. Usually, this taking up of the backlash in the intermeshing projections is effected by the operator through a change in but one of the j aw-pivots. The effect of this is to alter the central axis of the pair of aws, which would modify the angle through which the clamping devices turn in presenting alternately a heel and a top-lift. In such event, the desired 90 degrees of rotation may be restored by a change in the extent of projection of the stop-sorews 46.

To change the relation of the heel H, grasped by the jaws 54:, to the die-block-openings, thus providing for the most effective location of the nails in heels of one size or another or those differing in pitch, the slide 34, and thus the swing-plate as a whole, is adjusted. The illustrated means for the pun pose consists of a screw 130 turning in a lug rising from the slide and having threaded engagement with the bracket-extension 28. Since the shift from the heels of mens to those of womens shoes is of substantial extent, it is facilitated by a quick-and-slow adjustment, furnished by a partial nut 132 (Fig. movable in a recess in the bracketextension and carried by a stem 134 and normally pressed into engagement with the thread of the screw 130 by a spring 136. The stem furnishes an actuating portion projecting from the nut-section through a lateral bore in the extension 28, the spring lying within this bore about the stem and being interposed betwen the nut-section and a plate 138 closing the end of the bore. Upon the entren'iity of the stem is a head 14.0 to be grasped by the operator to withdraw the nutsection from engagement with the screw when the quick adjustment is desired.

Located between the jaws 5-1 is a back stop or gage 76 for the heel H, fixed upon the forward extremity of a plate 7 8 arranged to slide in ways in the top of the swing-plate and being slotted at 80 to permit the passage of the spindle 38 and the sleeve in which it rotates. At the opposite end of the plate 7 8 is ascrew 82 arranged to rotate in a yoke 84 fixed to the swingplate. The screw is threaded into the plate 7 8, and when turned moves said plate, and therefore the back stop 76, in one direction or the other, thus changing its relation to the ends 58 of the jaws. This adjustment alters the points along the curved periphery of the heel at which the ends of the jaws engage it, so it may be most firmly held against displacement under the influence of its weight or of jaw-pressure.

Carried in ways 85 in the swing-plate, below the jaws 54, is a slide 86, upon which are mounted top-lift-holding jaws 88, 88. The form of these jaws may be substantially identical with that of the aws 54, 54, so that they may all be stamped out by a single die. They are connected by teeth 90 corresponding to the teeth of the heel-holding jaws, and are arranged. to oscillate about adj ustable pivots 92 imilar to the pivots 56. A pressure device 9% forces surfaces 96, 96 toward each other for engagement with a toplift in the same manner as the heel-j aws.

Between the jaws 88, 88 is a back stop 98 carried by an arm 100, which first extends in a generally horizontal direction below one of the jaws, then turns and descends vertically to the lower portion of the swing-plate, where it again assumes a horizontal direction, being connected to a slide 102 movable in ways 104. A screw 106 turns in a bracket 108 depending from the yoke 84, and is threaded through a lug pr jectin from the slice 102. By the rotation of this screw, the advance or withdrawal of the back stop 98 between the jaws 88 may be effected, so that the correct positioning of the top-lift for heels of different sizes and pitches may be accomplished. This,

" it will be seen, is independent of the similar effect obtained for the heels by movement of the slide 34 with the jaws 54:.

After the adjustment of the back stop in accordance with the character of the top-lift operated upon, it may be desired to vary the relation of the clamping jaws to said back sto This permits the engaging portions of the aws to be brought into contact with the periphery of the top-lift at a greater or less distance from the breast, so the retention of the objectmay be assured. Were the jaws to engage the top-lift at points too far toward the rear, it will be obvious that the curvature of the periphery would tend to cause its ejection by the pressure against it. This adjustment may be effected for the jaws 88 a movement of their supporting slide 86. To this end, a screw 110 turns in a lug depending from the slide, and is threaded into the lower portion of the swing-plate. Rotation of this screw, by its engagement with the lug causes a movement of the slide 86 to change the distance of the engaging extremities of the jaws from the back stop.

Above the jaws 88 is located the usual spanker-plate 112, this being forced against a top-lift grasped between the jaws 88 to force it upon the ends of the previously-driven nails which have been left projecting from an attached heel. To allow the forward edge 114 of the spanker-plate to be differently positioned longitudinally of the jaws, so that it will serve with different sizes of top-lifts as a gage by which the operator may determine the proper angular relation of the toplift between the jaws, it is fixed to a block 116 movable along a screw 118, the inner end of which turns in the swing-plate. The distance through which the spanker-plate must be moved for this purpose may be considerable, as when a change from the nailing the heels of mens to those of womens shoes is made. The use of a threaded adjustment only in this connection would materially delay the operator. I therefore provide both a quick and a slow adjustment of the spankerplate. The screw 118 passes through an unthreaded bore in the block 116, and at one side of this bore, in a recess in the block, is located a threaded section 120 furnishing a partial nut. This section is fixed upon a plate 122 movable in a depression at the outer side of the block. The plate, above the nut-section, has a horizontal stem 12% (Fig. 6) projecting into a bore in the block and being provided at the oaposit-e side of said block with an enlargement or head Surrounding the stem between the inner end of the bore and the head 126 is a spring 128, which acts to hold the section 120 normally in engagement with the thread of the screw 118. By pressing upon the head 128, the operator may entirely free the screw 118 from threaded engagement, so the spanker-plate may be carried back and forth by direct movement. This furnishes a very rapid adjustment when the difference in size between the parts to be held is considerable. Upon release of the head 126, the spring 128 carries the nutsection 120 into engagement with the thread of the screw. Then, by turning said screw, the spanker-plate may be moved more slowly and with greater precision. In this way, the spanltenplate may be finally accurately adjusted; or this rotary threaded adjustment may be utilized when the distance through which the spanker plate is to be shifted is relatively slight.

A slot 142 in the loader-arm receives a pin 144i rising from the usual safety-bar 1-l6 mounted to reciprocate upon the bracket 26. This safety-bar, by the engagement of the slot with the pin, is moved when the loader is carried over the die-blocl to prevent movement of the starting lever of the machine, as is made clear in Patent No. lei-6,885, pre viously mentioned. This guards against actuation of the machine when the loader-block is in a position in which it would be struck by the descending drivers. By locking the safety-bar, the oscillation of the loader-arm may also be prevented, since the presence of the pin 144 in the slot 142 holds the loaderarm when the safety-bar cannot be recipronted. Such a locking of the safety-bar I employ when the swing-plate is in top-littpresenting position to avoid the possibility ot a load of nails being deposited upon the top of the spanker-plate. To bring this about, there is arranged to slide upon one of the walls 52, at right angles to the safetybar, a latch 1 18 (Figs. 1 and 8) having a locking projection 150 for engagen'ient with a depression 152 in the rear side of the safetybar. To maintain a normal withdrawal. of the latch from the depression 152, a spring 15% (Fig. 7) is situated in a recess in the top of the wall 52 between the end of said recess and a depending portion ot' the latch. Fixed upon the top oi the spindle 38 is a spring-arm 158. The angle at which this arm projects from the spindle is such that as the top-lift-holding device B approaches the die-block, the end of this arm engages the rear portion of the latch, and forces it against the spring 154C into the satety-bar-depression 152. Therefore, before the spankenplate arrives beneath the dieblock-openings, the safety-bar is locked, and upon an attempt to move the loader-block over the die-block, the wall of the slot 142 contacts with the now locked pin 144:, so that a delivery oi. nails upon the top of the spanlter-plate is impossible. The yield of the arm 158 circum'l erentially of the spindle 38 allows for an excess of its movement over the travel of the latch 148.
