Patented Jan. `9, 1940 UNITED 'STATES f PATENT ori-ics 'v t 2,186,155 MACHINE FOR'NAILING `SHOE BOTTOMS Louis P. Tremblay, Iiewiston, Maine, assigner to United Shoe Machineryy Corporation, Borough of Flemington, N. J., a corporation of New Jersey Application April 22, 1938, ,Serial No. 203,629
v ,12 Claims.
tween the heel-seat of the shoe and a full-length Asole or may be attached to the heel-seat and In either case, they commonly taper from their maximum thickness at the back ofthe shoe to a reduced forward edge in the Vicinity of the breast-line, giving a positive support for the entire arch od? the wearers foot. The length of this wedgeportion is such'that it cannot be attached properly by a single nailing, so the customary practice is `to'operate upon 'it by either two or three heelattaching machines. For example, the usual five nails may be inserted through the heel-seat of the shoe intothe rear of the wedge, then a pair of nails driven at the archabout midway of the wedgefand finally a second pair inserted at the thin edge of the wedge, somewhat to therear yof the breast-line. 'Ihe driving of the iirst set presents no special diiculty, kbut in connection with the other two sets,the 'counter-portion 'of the upper is spaced from the rear Aof the jack, so its locating effect upon the work is lost, and the inclinationl and curvature of the wedge at itsforward extremity requires such an angle between the jack-top upon which the shoe is supported and the hold-down by which `the clamping pressure is applied to the bottom, that there is a component vof the force tending to displace the work rearwardly. It is an object of the invention to both position the wedge-portion accurately with respect to the jack-top and to retain it against displacement during thek operation of the machine.
In the attainment of the aboveobject,y .there is combined with a jack Vor other shoe-support and a head or memberby which :pressure is exerted upon the treadsurface,a member mounted upon the lpressure Ymember-tor contact withthe rear of the'Wedge-portion. kBy thus bringing tcgether the wedge-contacting member and the pressure member, the former may be locatedmost conveniently in the correctl wedge-gaging and wedge-retaining relation yand'there held, regardless'o'f the position ofv thepressure member. To properly applythe work-clamping force, the pressure member is adjustable, and to arrange for the insertion of the set of nailsat the chosen points, the contact member may be 'retained 'in different positions upon `the' pressure member;
In the vparticular form of the invention disclosed herein, there is a jack of a machine adapted for the inside-nailing of heels andupon which a shoe may be supported for transverse movement,
together with a cio-operatingpressure-head. The pressure-head carries a tread-block upon which is mounted a gage member arranged to position the shoe in its transverse movement. On this block aslide may be movable longitudinallyA of a jacked shoe, said slide having upon it a fork or abutment situated at thev rear of the wedge-portion. The slidemay be movable in a recess in a plate secured to the tread-block and may be provided with teeth engaged by a detent movable upon'the plate. The arrangement of these teeth is preferably such that the slide is movable freely vforward to place the abutment in the desired wedge-engaging position, while rearward movement under the iniluence of displacing forces eX- erted upon the wedge'is prevented. The detent may, however, be released to permit rearward adjustment of the slidel and abutment. If desired,
an adjustment ofy the abutment-fork uponk the f slide heightwise of the wedge may be provided. In connection with the terms wedge or wedgeportion, it is to be understood that this invention Acomprehends equally its co-operation with a 'wedge which is inserted between the heel-seat and sole ofv a shoe and with one which, at its forward extremity, ymeets a short sole. The wedge may be considered either as a filler-portion or as a heel.
In the accompanying drawing, which illustrates a particular embodiment of the invention,
Fig.'1 shows inside elevation portions of a jack and the hold-down of the machine for attaching heels by inside-nailing, and with which is associated my improved positioning and retaining means, and
Fig. 2 is a section on the line II-II of Fig. l.
At I0 appears the upper portion of a shoe-supporting jack, in vertical passages in which operate drivers I2 for the insertion in the jacked work of nails N supplied tothe passages. A pressure-head, a portion of which is shown at lll, is movable toward and from the jack, serving, in the usual manner, to clamp thereon a shoe and a heel-portion to be attached. Guided in segmental Ways I6 in the head is a tread-block I3 adjustable as to angle, fore and aft of the jack, by a worm and worm-segment 2l). justmenttransversely Aoi the jack, the block lll has a lower section 22 whichmay be varied in position in ways 24 upon the upper section and fixed in place by a screw 26. Because ofthe rather steeply inclined surface which the block 22 is called upon to engage with work of the character to which this invention especially applies, the lower tread-surface 28 is correspondingly inclined. This furnishes a mean relation between the elements of the gearing 20, such that there may be substantial adjustment of the angle of the block in opposite directions, the worm still remaining in full mesh with the segment.
The under, tread-contacting .surface 28 of the block 22 is herein disclosed as upon a plate 30, secured upon the block by screws 32 and dowelpins 34. In the upper side ofthe plate is a slot or recess 36, this slot extending longitudinally of a jacked shoe. In lthe slot, ay slide-bar 38 is movable and has at its forward extremity a depending angular portion 40, upon which is mounted an abutment, shown as in-the form of a fork 42, the arms of which may be padded at 4Q. Accidental withdrawal of the bar is prevented by a pin 45 rising from its inner end. The fork is for'engagementby such a work-piece as a wedge-portion W, which preferably has been partially attached to the insole z' of a shoe S by nails n. The fork may be secured to the bar-portion 4D at different distances from the bar, and therefore from the tread-surface of the wedge W, by a slot-and-screw connection 46. Formed in one edge of the bar are ratchet-teeth 48 ,inclined inwardly and rearwardly. In the plate 38 adjacent to the ratchet-teeth is a recess 50, in which a detent 52 is pivoted for engagement with the teeth under the influence of a spring 54. A projecting tail 56 of the detent Vlies outside the recess, where it may be actuated by the operator to release the bar. l Y A It may be assumed that the shoe S with its partially attached wedge-portion W comes to the nailing machine which is equipped, in accordance with the present invention, for the insertion of the nails N at the forward extremity of the wedge. To prepare for the location of the desired area of the wedge over the drivers I2 which are to be used, the operator may either press the bar 38 from him, the detent 52 yielding, or he may release said detent by pressure upon the tail 56 and then draw the bar to the proper point. The inclination of the tread-contact-surface 28 upon the block 22 will approximate the angle at which lies the outer surface of the wedge or the overlying surface of the outer sole s when the insole z is in most complete engagement with the jacktop, or the angle of the surface 28 may be more exactly adjusted by the gearing 20, this movement being in the plane of angular adjustment of the block. Having jacked the shoe, the operator lowers the pressure-head I4, and before the surface 28 contacts with the work, he slips back the shoe upon the jack-top, until it is correctly located by its engagement with the fork 42. Then, final clamping pressure is applied, and the attaching nails driven. In addition to the effective vertical pressure, the action of the inclined surface 28 upon the inclinedwork-surface will produce. a horizontal component, theeect of Which will be to tend to displace the wedge and, with it, the shoe rearwardly, or toward the end of the wedge of greatest height. This force, however, is resisted by the fork, which holds the work securely in place against displacement. It will be seen that since the locating and retaining abutment is mounted directly upon the angularly adjustable tread-block, and since its own adjustment is always parallel to the tread-engaging surface of the block,.when the abutment has been arranged in the chosen relation heightwise of the wedge, it will always so remain, regardless of adjustments.
