24 Claims.-

My invention relates to machines for attaching heels to shoes, it concerning more particularly the means for presenting heel-portions, as a base and top-lift, to a jacked shoe for their attachment.

In heeling shoes, it is sometimes desired to use bases and top-lifts which have been prebreasted, or brought to a condition at the breast-surfaces at which only a finishing operation is required after attachment. This is advantageous, because '10 it avoids the danger of cutting the outsole during breasting or of exposing a depression in the sole adjacent to the heel after the breast-cut has been made, the depression being Vcaused by the pressure applied in the heelerto a sole in temper. When thus operating upon prebreasted heels, it is not satisfactory to locate them in their holders in the usual manner by contact of a fixed fork with the rear surface in connection with an opposite yieldable breast-bar, Differences 2o in the amounts previously taken from the breasts will prevent accurate registration of the top-'lift yand base and will vary the pitch of the attached heel. Consequently, it is desirable tolocate'the heel-portions by contact with the breast, and, for

this purpose, the breast bar is normally fixed upon its swing-plate or carrier, while the rear fork is yieldable.

With such an arrangement as that just described, when there is a change in the character of the heel to be attached, it may be necessaryto shift its portions, as the base and top-lift, for- Wardly or rearwardly upon the carrier. I facilitate this operation, as an object of my invention, by providing means to move one of the heel-contacting members of one of the holders for a heelportion, as that for the base, and through connections to this, effect the correct movement of a contact member for the other holder, orrthat for the top-lift. Thus, by a single action on the part of the operator, the elements are simultaneously located in both holders. Since it may be preferable not to impart the same movement to the members, I may furnish means for varying the relative normal positions of the members.Y VIn 4 this way, for example, when the'eattachmentv of .the heel is completed, the base may be caused to project somewhatoutside the top-lift. The breast of the base may then be scoured into registration with that of the lift, using the latter as a gage.

In the embodiment of the invention Aherein disclosed, the breast-barsV of the ybaseand liftholders are movable upon a swing-plateV and V`are connected by a bar having sliding engagementY with each. By a projection Vfrom the connecting 5 barguided in the plate, a movement-of one breastbar will be communicated to the other in a deniterelation. `By altering the position of the projection upon Vthe connecting bar, the initial relation between the breast=bars may be varied to give departures fromiexact registration `:of the 5 breasts of thebaseLand lift.

When a jacked shoe to which a heel-base has been nailed is brought into engagement with a top-lift in its holder for the spanking operation, the `shoe may be turned slightly about the longi- 10 tudinal vaxis of the jack, especially `if a bandclamp .is.not employed, so `the breasts of the two heel-portions will be out of registration angularly about such axis. lIt is another objectof my invention to correct this condition. For this .purl5 pose, the heel-contacting member, as the breastbar, which is employed to determine the position of the heelportion,is arranged to swingunder the inuence of the work so it may thereby restore the disturbed registration. Further, the member 20 may be provided with means to change the position of the Work to aid in thecorrecting action. As herein disclosed, the breast-bar of the toplift-holder'has a supporting or body-portion, a work-contacting portion and an intermediate 25 yieldable portion. This work-contacting portion has a downwardly and inwardly inclined surface which the breast of the attached base upon the jacked shoe will engage when spanking pressure is applied. The forces thus created `tend to turn 30 the shoe with its base upon the jack and also to turn the yieldable contacting portion of the breast-bar and thus the top-lift in the holder. In this manner, substantial registration between the heel-portions is assured. Y Y 35 In the accompanying drawing, illustrating one of the several possible forms which my invention may assume,

At l0 (Fig. l) vappears a fragment of the frame of a heel-attaching machine, such as is disclosed in Letters Patent of the United StatesY No. 1,157,688, Glidden, October 26, 1915, upon which frame is vertically movable a crosshead l2, the die-block I3 ofr which has openings to receive nail-drivers lli. VBetween Ythe die-block .and a 55 jack i6 a shoefas shown at S in Fig. 2, is Y f with the base.

clamped for the base-nailing and top-lift-spanking operations.

A swing-plate or like carrier I8 is pivoted on the cross-head at 2B and by connections at 22 may be oscillated to present above the die-block, in operating position, either a base-holder b or a top-lift-holder t. The base-holder has a bar 24 which will locate by contact with its inner edge a heel-base, indicated at B in Fig. l. From this barprojects rearwardly a shank 26 guided in ways 28 on the plate. By a screw 30, mounted at 32 to turn upon the swing-plate and threaded to the shank, the breast-bar may be adjusted in or out to change its relation to the points of insertion of the nails which are carried upon the drivers I4. The breast of the base will be held against the bar 24 by a fork 34, having its shank 36 guided in ways 38 upon the swing-plate and urged against the rear of the base by a spring 40.

The top-life-holder t has a rear fork 42, mounted and urged outwardly by a spring 44 in the same manner as that of the base-holder. It is opposed by a breast-bar 46, the shank of which is guided upon the swing-plate, as is that of the associated holderbut without adjusting means connected to said shank. This breast-bar for the top-lift is made in three parts: The support or body 46 has secured to it a layer of yieldable material 48, which may be of rubber vulcanized in place. To the free face of this rubber there is attached, also by vulcanization, a work-contacting plate 5I), which may be considered as a yieldable breast-bar. By thus connecting the plate 50, it may be swung or displaced angularly, having a limited movement of oscillation about avertical axis, as that of the jack I6 when this is in operating position. At the inner upper edge of the plate 50 is a downwardly and inwardly inclined surface 52 leading to the work-contacting surface 54. This surface 52 is so located that it will be engaged by the corner of the breast-edge of an attached base as this descends for the liftspanking operation, unless said edge is already in position to register correctly with the top-lift. When out of registration, this contact will exert a turning force upon the shoe S about the lastpin 56 of the jack, thus tending to correct the location of the breast of the base with respect to that of the top-lift in the holder. At the same time, the contact-plate 50 is subjected to an opposite turning force and, yielding upon its mounting, will tend to bring the lift into registration This -double action shortens the time Vrequired to eiect registration, this being especially useful because of the rapidity of the spanking movement and the short distance through which it occurs.

To communicate the adjusting movement of the base-breast-bar 24 to thetop-lift-breast-bar 46, these two bars are formed with longitudinal ways 6B and 62, respectively. In these ways, the angularly disposed arms of a bar 64 are movable. This connecting bar 64 is compelled to move in a predetermined path by a projection from its under side, this being shown as a roll 65 arranged to travel along a slot 68 in the plate I8. 'Ihe slot preferably lies along a line extending through the swing-plate axis 20 and bisecting the angle between the center lines of the holders b and i, which pass through the same axis. The roll 6 5 may be varied in position upon the bar 64 by adjustment along a slot 10, in which it is clamped by a bolt I2. With the roll located at the center ofthe juncture of the arms of the bar 54, movement of thebreast-bar 24 by the adjusting screw 30 will correspondingly carry the breast-bar 445 with its plate 5l] in or out, from initial positions at which registration would be effected between the breasts of a base and a lift in the holders. The difference in the direction of travel of the two breast-bars will be compensated for by the capacity for relative movement between said bars and the connecting bar. Any adjustment or the breast-bar for the base will thus be transmitted to that for the lift to give throughout the entire range unfailing registration. If, on the other hand, a projection of one breast-edge beyond the other is desired, then the roll S6 is shifted in its slot so the arms of the bar 64 will change the normal relation of the breast- bars 24 and 46 in the proper direction. When the roll is xed in place, this locates the contact-surfaces of the breast-bars at different distances from the axis of the swing-plate, and one of the breast-surfaces of the attached base and lift will project beyond I the other. As long as the roll is retained in its chosen position, this relation between the two breast-bars will be maintained for all adjustments by the screw 3l).

In the use of this organization, the operator by the screw 30 positions the breast-bar 24 to give the desired location of the heel-base contacting with it with respect to the nailing mechanism of the heeler. In so doing, he communicates the adjustment through the connecting bar 64 to the top-lift-breast-bar 46 without further attention. Exact breast-registration or a definite amount of overlap will have been determined by adjustment of the roll 66. A heel-base B and a top-lift 'I' being in place in the holders b and t upon the swingplate I8 and a shoe S upon the jack I5, during the iirst half of an operating cycle of the heeling machine, the holder b is over the die-block, and the base is nailed in place upon the shoe by the action of the drivers I4. During the second half of the cycle, the connections 22 bring the holder t over the die-block. The nailing operation will have left the base upon the jacked shoe with the desired angular relation between its breast and that of the top-lift, and the application of spanking pressure will nd the heel-portions correctly located, unless the operator has turned the shoe angularly about the last-pin 5S of the jack. In that case, however, the displaced corner at the breast-edge of the descending base will engage the inclined surface 52 of the contact-plate 555 upon the breast-bar forthe top-lift, exerting upon the work a force tending to turn the breast of the heel into registration with the surface 54 of the plate and of the top-lift-breast. Simultaneously, the intermediate portion 48 of the breast-bar yields, so that a further corrective movement of the contact-plate itself in the opposite direction is. caused. Thus, the breasts of the base and top-lift are brought to the desired relation.
