LASTIN'G-MACHINE. Y

Specification of Letters Patent;

Patented A an-.16, rat a ToaZZ whom it may 00mm.-

Be it known that I, ANGELO PERRI, a citizen of the United States residing at Groveland, in the county of lissex and State of Massachusetts, have invented certain new and useful Improvements in Lasting-Ma-' chines, of which the following is a specifi cation, reference being had therein to the accompanying drawing.

This invention relates to lasting machines, and more particularly. to a novel shoe holding device or jack and to wiping mechanism cooperating therewith.

In the lasting of shoes a sectional Wooden last is usually employed for giving form' to the shoe. The shoe upper is; required to be assembled with the sole about the last,

as a form, and the lasting process may comprise the steps of first pulling-over the flexible upper about the fore part of the,

shoe and thereafter wiping the extending side margins, and the margins at the heel and toe. Such wiping consists in forcing, smoothing and pressing the overhanging material of the upper into place about the last and sole, where it may be suitably secured preparatory to subsequent operations including attachment of sole and upper. In my prior Patent No. 1,168,963, granted January 18th, 1916, I have shown a machine in which all of the above described steps or operations may be performed, the machine comprising a shiftable jack which holds the shoe, a pulling-over mechanism, and heel and toe wiping mechanisms.

The present invention in its entirety involves not merely the construction of jack herein disclosed, and the novel features thereof per 'se, but also wiping mechanisms for the toe end and the heel end, respectively, of shoes, possessing certain characteristic features giving advantageous cooperation with features of such jack; and the principal object of the present improvement to afford a shoe holding ack and a lasting machine including the same, which will be the same, embodying features of the present invention. The novel jackmay be variously employed, but, as herein disclosed, is more especially designed to be employed in a socalled bed lasting machine, in which the inverted shoe is inserted after having been pulled over, and in which usually both the heel and toe portions of the shoe upper are wiped and secured.

The toe wiping mechanism and the heel wiping mechanism which I prefer to employ in coiiperation with the'shoe holding jack hereof are herein sufliciently illustrated to give a complete understanding of the relation of such mechanisms to the jack and to each other. However, the toe wiping mechanism is not herein shown in complete detail, and neither is the heel wiping mechanism, as these are the subjects of separate patent applications, to which reference should be made for further details. The toe wiping mechanism is completely illustrated and convenient use. for the wiping of both shoes, that is, the right and left shoes of a pair. A machine which may be quickly changed over for this purposeis very ad vantageous in permitting both shoes of a pair to. be completed before operating on other shoes.

Another object is to provide the combination with lasting means of'a jack adapted to hold right and left shoes of various shapes, styles and sizes with the apex-line, that is, the line joining the apexes of the toe and heel of the shoe always standing in the same longitudinal direction, this being preferably accomplishedherein by a transverse swinging of the jack, avoiding any bodily transverse shiftingof wiping mechanism.

It is another object hereof to provide a lasting machine wherein the wiping mechanism may be bodily swung, subsequent and independent to the adjustment of the jack, and substantially about the apex of the shoe contour at one end as a center, in order to set the line of wiping action into proper relation or coincidence with the center line of the shoe at that end.

It is another object hereof to provide a shoe holding jack which may be adjustably swung substantially about the apex of the heel to bring the apex of the shoe toe into longitudinal alinement with the heel apex, in combination with cooperatively adjustable heel and toe wiping mechanisms.

Another object is to provide a jack for a lasting machine, which, including the heel rest and the toe rest and the hold-down, may be bodily swung about a given center or axis. jack which may be so swung as a unit and is provided with relatively movable heel and toe supports adapted to receive shoes of varying sizes.

Another object is to provide a jack, which, by the action of removing a shoe and inserting its mate, automatically symmetrically reverses the position of the jack or otherwise adapts it to the lasting of the' mate. Anotherobject is to provide for alternately locking the jack in its two positions in which rightand left shoes are to be lasted.

Another object is to provide a lasting machine wherein the readjustment of the jack, whether automatic or otherwise, for rights and lefts performs an automatic adjustment upon the wiping mechanism to cooperate therewith; particularly that the lateral swinging of the jack will reset the line of action of the heel wiping mechanism so as to lie in a line coincident with the center line of the heel part of the shoe.

Another object is to provide for the shoe holding jack a hold-down of extremely simple and effective construction and the use of which dispenses with the usual abutment at 0113 end of the shoe, while wiping the other on To the attainment of the above referred to objects and advantages the present invention consists in the novel lasting machine or wiping mechanism, and the novel features of arrangement, design, comblnatlon and detail herein illustrated or described and claimed.

The accompanying five sheets of drawings contain the following figures.

Generally speaking, a bed lasting machine such as that indicated herein may comprise a base 19, upon which are supported the jack or shoe holding mechanism 21, and to the right of the jack the heel wiping mechanism 22, and to the left of the jack the toe wiping mechanism 20.

Since the novelty hereof is not restricted to the construction of the jack mechanism 21, but resides also in the toe and

heel wiping mechanisms

20 and 22, it will be necessary to describe the three mechanisms. The wiping mechanisms, however, being completely described in my copending applications, need not be so fully described herein. It will be convenient to first describe generally the toe wiping mechanism, and subsequently the jack and the heel wiping mechanisms. The same reference numerals will be employed for all three patents.

Referring first to the toe wiping mechanism 28, the description in said application 83,540 may conveniently be condensed as follows.

At the left of the bed is an elevatable support 23, which may be lifted and lowered threaded lug 27 depending from the carriage. Upstafiding from the carriage are brackets 30, which at their upper ends give support to the toe Wiping mechanism or head. At the extreme right of the toe wiping head are seen the wiper plates 60, 61.

The movements and adjustments of the toe wiping mechanism are various. In addition to the longitudinal adjustment toward and from the shoe by the hand-wheel 26 and the lifting and lowering movements by the pedal 24, the toe Wiping head is capable of being bodily tilted longitudinally to different degrees from the horizontal, for

example, as indicated in Fig.1. This tilting is permitted by trunnion bearings 31 at the top of the brackets 30, these giving support at diametrically opposite points to an upright bearing ring 32 carrying the wiping mechanism. The ring 32 may be tilted from the vertical by suitable connections from a hand-wheel 36. Also the wiper plates are designed to have operative movements-toward and from the shoe, the advance of the plates being accompanied by a convergence thereof and their retreat by a swinging apart or divergence thereof. 'Another movement or adjustment, and one which is characteristic of this toe Wiping mechanism, is a movement of inversion, by which the single set of wiper plates is adapted from one shoe to the other, the inversion insuring symmetry of contour. The advancing and retreating wiper devices are so arranged as to be adjustable to various inclines from the longitudinal axis of the machine. This is necessary from the fact that shoes are seldom straight, and the center line of the shoe forepart extends at various inclines from the center line of the rear part. This adjustment is performed in a characteristic way, the swing of the mechanism taking place about a center substantially coinciding with the tip or apex of the contour of the wiper plates. The mechanisms for performing these last two mentioned adjustments are so combined and harmonized that the inversion of the Wiper plates to reverse them in changing from one shoe to another simultaneously and symmetrically reverses the direction or incline of wiping action. Another adjustment is a lateral tilting to accord with variations in shoes, but this requires no particular reference in the present patent. A hand-wheel 145 may be turned for varying the lateral tilt. All parts of the machine are constructed, combined and adapted to enable the quick and ready change-over required to enable. the successive wiping of rights and lefts, thus obviating the practical disadvantages of lastingfirst a number of rights and then a number of lefts, as explained in application 83,540.

The inverting operation referred to, which symmetrically efl'ectsa reversing of the contour and the incline of action of the lateral tilt of the wiper plates, ispermitted by bodily mounting the wiper plates and their supporting devices within a rotatable shell or flanged ring 34, engaged within the upright bearing ring 32. The actual revolving of the shell 34 may be accomplished by a rightwardly projecting handle 130. Suitable stop devices or lugs serve to properly position the revoluble shell when the inverting operation is performed. A lever 150 is connected tov cause the unlocking of the shell when desired to invert it by the handle 130.

The change of incline of wiping action is effected by mounting the wiper plates and their supporting devices upon a laterally shifting carriage 45, which engages with arc-shaped tracks 43 secured to the shell 34, the carriage having special correspondingly shaped ribs 47 for this purpose. As indicated in Fig. 4, the arc-shaped guides and ribs are struck about the center F, which is the apex of the contour of the wiper plates. The adjustment may be actually effected by hand-wheel 120 and suit able connections, which serve tothrow the carriage 45 toward or from a truelongitudinal position to the degree required by the particular shoes being lasted.

In order to permit the advancing and retreating movements of the wiper plates 60, 61, the latter are su ported at the forward end of a longitudinally sliding carrier 50, mounted at the center of the wiping head or with its axis coincident with the .axis of the transversely sliding carriage 45. The carrier 50 is a generally cylindrical member, but is splined within the circular part of the carriage 45 so as to partake'of any revolution imparted to the carriage through the surrounding revoluble shell. The Wiper plates 60, 61 are at the righthand or forward end of the carrier 50, and thecarrier is caused to move longitudinally by connections at its opposite or left end.

As will be clear from Fig. '1, the parts supported by the carrier 50 are symmetrical, so that the wiping mechanism may be operated in either of two positions, one inverted with respect to the other. As indicated in Figs. 1, 3 and 4, the carrier 50 is laterally enlarged in the form of wings 54, and forward of this point it is designed to accommodate the wiper plates 60, 61 and associated parts.

The swinging toward each other or converging of the wiper plates during their operative or advancing movement may be efl'ected in various ways, for example, as illustrated in said application 83,540, in' which the two plates simultaneously swing about their point of juncture, which is the same center F about which adjustment is effected for incline of direction of wiping action. A. toothed bracket 73 is one of the elements of the mechanism for swinging the plates. I

Both-above and below the wiper plates are blocks 80, whichassist in the wiping operation. The blocks which are above the wiping plane stand between the plates and the abutments or cover pieces 7 5 and give rigid reinforcement during the wiping operations. The blocks 80 which at any time are beneath the wiping plane are capable of yielding, so that contact with the shoe will repress the blocks, and the blocks are made to serve as-gages by predetermining their extent of yield. In order to render the underneath blocks yieldable and the upper ones unyielding, a vertically sliding lock device or bar 90 may be used. This requires to be lifted whenever the wiping head is v inverted. V

The controller or instrument for manipulating the wiper plates may be in the form of an operating lever 100, located convenient for the lefthand and supported by a bracket mounted on the bearing ring 32. The wiping lever 100 extends forwardly and swings rightward and leftward. The lever is provided 'with a latch 103 for looking it and the wiper plates in their advanced positions. The movements of the actuating lever are communicated to the carrier 50 by means of a. downwardly extending tele-- scopic rod 107. The connections between the lever and the carrier, including the rod 107, are such as to freely permit the previously recited adjustments of longitudinal and lateral tilt, as well as the bodily inversion of the wiping head.

Coming now to the jack mechanism 21, this, as already explained, comprises shoe supporting devices permitting the shoe A to be swung horizontally about a, vertical axis or center located at D near or approximately at the tip of the heel. This permits the forepart of the jack to be swung toward and from the operator, or transversely to the longitudinal axis of the machine in adapting it and theshoe to the toe wiping mechanism. It has been explained that the adjustment of the angle of action of the toe wiping mechanism is performed about the point or center F as an axis, F being the apex of the contour of the toe wiper plates. This point, of course, advancesand retreats during the wiping movements. When the plates have been brought up into contact and conformation with the toe of the shoe, the apex F of the plates will coincide with the apex of the shoe toe, which latter may be designated F. Since the bodily-adjust ment of the toe wiping mechanism toward and fromthe shoe is strictly longitudinal in direction, it follows that the point F, and.

therefore the point F, when the plates are in position to conform with the shoe, will always be in the same longitudinal axis, plane or line. It ismy preferred plan that the shoe apex F shall be in the same longitudinal axis as the center D about which the jack swings. In other words, every shoe, straight or crooked, right or left, placed in this machine will be so located that the line FD joining the apexes of the toe and heel will be constant in location and direction.

The diagram, Fig. 11, indicates these relations of the parts. This diagram indicates in full lines a left shoe of decided curvature and in dotted lines a more nearly straight left shoe. The longitudinal axis HH of shoes and for rights and lefts. The centers or apexes D and F are both in this axis when wiping. In order to bring the shoe into the position indicated, the jack will be swung about the center D until the shoe toe apex F lies. in the longitudinal axis HH. This is indicated by the coincidence of the wiper plate apex F and the shoe toe apex F. In this lateral swinging of the jack for rights and lefts and for different shapes and styles of shoes, the jack assumes different positions, which may be indicated by laying out the axis of the jack itself. This axis will seldom coincide with the longitudinal axis H-H. Thus, in the supposed instance the forepart of the jack has been swung out into the direction D-J, which represents the axis of the jack for the left shoe A. With the jack lying in the position DJ and the apex of the shoe toe at F on the longitudinal axis, the toe wiping mechanism will now be adjusted so that its angle of action will lie along the'line K-F. This adjustment is in effect performed by swinging about the apex F. This adjustment, therefore, is readily made, so that the wiper plate contour will conform with the shoe toe and so that the angle of action K-F will substantially coincide with the center line of the forepart of the shoe, as indicated.

The readjustment for a right shoe which is the mate of the left shoe A shown in full lines, it is understood, would be easily effected by a more symmetrical shifting of the points J and K across the axis HH. In other words, it is merely necessary to invert the wiping mechanism, which, as explained, reverses the angle of action, and to swing the jack forwardly until its axis is forward of the longitudinal axis by the same extent that the jack axis D-J is indicated to the rear thereof.

When, however, a decided change in the shoe style is made and a "comparatively straighter shoe A is substituted, as shown in dotted lines, the readjustments will not be symmetrical. The more nearly straight the machine is constant for all shapes of mamas the shoe, the more nearly will the jack axis approach the longitudinal axls. Therefore, the first readjustmentis to swing the ]ack axis from DJ to DJ. This is such as to bring the apex of the shoe toe to the same point F on the longitudmal axls. The angle of action of thetoe wiper plates will be correspondingly adjusted, as indicated at KF, which is the new center line of the forepart of the shoe.

The structure of the jack mechanism is best shown in the partly-sectioned front view, Fig. 6, in connection with the top view, Fig. 5, additional details being shown in Figs. 1, 2, 7, 8 and 9. .The jack comprises a toe rest 155 and'heel rest 156, both supported on a jack base plate 157 of generally square form, located above the top plate or bed of the base 20 of the machine. The jack base plate 157 is movable over the bed by swinging about a center or verticalaxls D, located substantially. beneath the tip or apex of the heel of a shoe or last held on the jack. As will appear, the heel rest is adjustable toward and from the toe rest/ Also, the jack base plate carries a hold-down,which clamps a shoe in position upon the toe and heel rests. 4

This entire jack mechanism is bodily shiftable, the jack base plate for this purpose being secured to a vertical shaft 158. The toe end of the jack base plate is provided with anti-friction rollers 1.59 running upon a machined portion of the bed. Before de-' scribing the swinging movements of the jack and the preferred mode of effecting them, it

.will be convenient to describe the toe and heel rests and the hold-down, all of which swing bodily with base plate 157 about fulcrum shaft 158. The toe rest 155 may for convenience comprise a resilient pad 160 pivotally mounted at the top of an upstanding bracket 161 bolted to the swinging end of the jack base plate. The vertical portion of the bracket 161 serves as a guide fora portion of the hold-down or shoe clamping mechanism.

The heel rest 156 consists of an upstanding member of solid construction, its base 162 being solidly, but slidably, mounted in the jack base plate. The-upper end of the heel rest is socketed in a usual manner to hold interchangeable pins 163. These pins to receive rollers 164 exteiiding transversely from both ends of the sliding heel rest base. This arrangement gives a very firm connection, and at the same time permits the heel rest to be longitudinally slid with facility.

The purpose of the sliding of the heel .rest is to permit relative approach and separation of the toe and heel rests to accommodate the jack to varying shoes and, as indicated,

toothed at 165 to receive a dog 166, which is pivotally mounted on the heel rest to engage and disengage the teeth 165. A spring 167 tends to lift the dog and at the proper time the dog is pressed down into engagement with the teeth by a hunter 168. This for convenience is a spring-pressed device mounted on the hold-down mechanism, so that, when the latter is depressed to clamp the shoe in place, the heel rest becomes automatically locked in position. The mechanism for clamping or holding the shoe down upon the toe and heel rests is best shown in Figs. 6. and 7 and in top view in Fig. 5. This mechanism is fitted and operated from beneath the shoe so as to stand out of the way when inserting and removing the shoe. The members which hold the shoe or press its sole downward are, therefore, in the form of hooks 170, there being one at each side, and these being applied to the shoe at a point between the toe and heel rests, but preferably at the ball of the shoe or near the toe rest. As seen in Fig. 7, the hold-down hooks 17 Gem adapted to be swung inward toward each other over the shoe and to be there pulled down into clamping position.

Convenient mountings for the hold-down hooks and the connections for causing them to swing together and descend in clamping a shoe, and vice versa in unclamping it, will now be described. The operations are controlled by a pedal 185, the connections to are forced apart in the manner subsequently to be described. The dotted lines in the upper part of Fi 7 indicate not only the extent of swinging o the hold-down hooks, but also the extent of vertical movement of their pivots and of the slide 171 carrying the same.

'Each hooked arm 170 is provided near its pivot with a shoulder or contact surface 173 adapted to be pressed upwardly for the purpose of separating the hold-down hooks against the tension of spring 172. For effecting the in and out swinging movements of the hold-down hooks, and also the up and down movements of the'slide 171 carrying the same, I have provided the following simple mechanism. This comprises an actuating bar 174 connected to and extending downwardly from the slide 171. This bar is adapted to be pulled down and moved upwardly under control of a pedal 185. The bar has a block and slot connection with the slide, permitting a limited relative movement. Thus, a lug 175 is formed on the slide 171, this acting as a block and engaging in a vertical slot formed in bar 174: at 176.. The parts are secured in alinement by the equalizing lever 177 pivoted to the block 175. The upper end of the actuating bar 174 has transversely extending contact arms 178 located immediately beneath and adapt ed to contact the shoulders 173 of the holddown arms. This cooperation is effected by the relative movement between the slide and bar permitted by the play of the block 17 5 of the former in the slot 176 of the latter.

When the actuating bar 174 is lifted, its contact arms 17 8 come up against the shoulders 17 3 of the hold-down arms, and the continued lifting movement serves to bodily lift the hold-down arms and the slide 171 carrying them, the spring 172 being strong enough at this time to resist the separation of the arms. After a suitable lifting of the holddown hooks in this way, the slide 171 comes in contact with a stop pin 179 mounted on the guide or bracket 161. This halts the lifting of the slide, and the continued rising of the bar thereafter forces the hold-down hooks and arms apart, until, when the upward movement of the bar is stopped by the block and slot connection 17 517 6, the holddown hooks assume the dotted position shown in Fig. 7. The descending movement of the actuating bar causes exactly the reverse operation, the hold-down hooks first swinging toward each other, so as to overhang the shoe, and then descending, the pedal finally pulling forcibly down and the parts becoming locked in the final position. Before describing the pedal connections, I will mention a device for locking the jack mechanism against accidental transverse swinging. It has been explained that the jack base plate 157 may swing transversely at the toe end about the vertical fulcrum shaft 158 as an axis, this shaft corresponding in position with the axis D, heretofore referred to. It has also be en explained that while the rollers 159 travel over the bed.

To the rear of the rollers 159 the bed is provided with upstanding teeth 180 in the form of a curved rack concentric with the swinging movements of the jack. Above the rack 180 the jack base plate at each side is provided with a spring lifted dog 181. These dogs are adapted to be forced downwardly to engage with the teeth 180 to lock the jack against transverse movement. This is effected automatically when applying the hold-down. The actuating bar 1741 is provided at front and rear with spring bunters 182.

The bunters 182 are similar to the hunter 168,previously mentioned. All of them are mounted on the descending actuator bar 174, and serve on the forcible descent of the bar to effect their respective locking functions. For convenience the hunter 168 is omitted from Fig. 7, although'its bearing lugs are indicated. Each bunter includes a powerful spring which permits its yielding, so as to prevent breakage, the spring being sufficiently strong to overpower the comparatively light springs tending to with- I draw the dogs 166 and 181, respectively, from the teeth 165 and 180, respectively.

When the actuating .bar 174 is pulled downwardly the hunter 168 with its strong spring is caused to press resiliently upon the dog 166, the light spring of which yields.

so that the dog is pressed into contact with the toothed device 165 below. At the same time the hunter 182 analogously presses the dog 181 downwardly into engagement with its toothed device 180. Thus the heel support is locked against longitudinal movement and the jack is locked against the swinging.

The descent of the actuating bar 174,therefore, not merely swings the hold-down hooks together and applies them on top of the shoe to clamp it upon the shoe rests, but also at the sametime automatically locks the heel rest and the jack base plate against accidental movement.

The connections from the pedal 185 for pulling down the actuating bar 174 and as seen in Fi 1, at its righthand end, and provided at its left end with a spring 188 tending to lift it and the pedal. Near the free end of the lever is an upwardly extending rod 189, to which is pivoted a slotted head 190. The-head 190 is guided to slide vertically, having for this purpose recessed cross arms 191 engaging opposite vertical guide rods 192, as seen in Figs. 6 and 9. The circularly flanged lower end of the actuating bar 174 rests directly on top of the cross head 190, and the two are so connected that the pedal movements effect the lifting and falling of the bar, while permitting transverse movements of the bar during adjustments of the jack mechanism across the bed of the machine. The slot at 193 in the crosshead is curved, being an arc struck about the axis D as a center. A pin or bolt-like extension of the actuator bar passes downwardly through the slot 193, and below, as seen in Fig. 7, is provided with ahead or stop in the form of check nuts 19 1. The check nuts are so placed as to produce a running fit, so that the check --nuts easily move transversely during any adjustments of the jack.

With the above described connections, the depression of the pedal 185 operates through the lever 187 and bar 174 to move the holddown hooks over the shoe, depress them into place and lock the heel rest and jack base plate against movement. The pedal and bar are themselves adapted to be locked in this position, so that the operator is relieved from holding down the pedal during the wiping operations, the other pedal 24 requiring to be actuated by him in lasting the shoe toe. For this purpose the pedal 185 is provided with a toothed rack 195 adapted to be engaged by an elongated pawl 196, constituting the lower end of a spring pressed lock lever, the upper end 197 of which is shaped to constitute a convenient handle for effecting the release of the pedal. when the shoe is to be unclamped.

The jack base plate 157 and the entire jack mechanism carried with it may be.

shifted transversely for rights and lofts either by hand or automatically. In either case I prefer to provide symmetrical stops to properly limit the swinging movement, and, by rendering these stops adjustable at will, the angle of the jack may be altered 1n different degrees to suit different styles of shoes.

For these purposes a pair of symmetrically opposite stops 200 may be employed, as seen in Figs. 8 and 5, these being located at a point suitably removed from the axis D of swinging, for example, somewhat to the right of the axis. The jack base plate 157 is indicated as being apertured to afford shoulders or stop contacts 201. Fig. 8 shows the jack centrally located, and therefore in contact with neither sto 200. When swung to either slde, one of the stops will be met, and the displacement to one side will necessarlly be symmetrical to the opposite displacement.

.To permit increasing or decreasing the swlnging displacement ofthe jack, the stops 200 are movably mounted to approach and recede from each other transversely to the machine. They are both guided and actuated for this movement by means of an ad justing shaft 202, having right and left screw-threaded portions engaging threaded recesses in the respective stops, so that, when the shaft is turned by the hand-wheel 203, the stops are moved together or apart.

It should be observed that moving the stops apart decreases the latitude for shifting of the jack. Therefore, to increase the angularity of the jack for a very curved shoe, the hand-Wheel 203'should be so turned as to cause the stops to approach each other to the proper extent. If the stops be thrown apart as far as permitted by the space between the contact shoulders 201, obviously this would centralize the jack and hold it against any lateral movement.

I prefer that, when the pedal 185 is operated to unclamp one shoe and to clamp the next one, this rising and falling movement of the pedal will, without any further attention from the operator, effect the symmetrical reversal of the position of the j ack, throwing it from one incline with respect to the lon 'tudinal axis of the machine suitable for a rlght shoe to an opposite incline suitable for the left shoe, and vice versa. For this purpose the fulcrum shaft 158, about which the jack swings, is constructed to extend downward to where it may be employed as a rock shaft to be rocked by a .suitable cam and stud arrangement under the control of the pedal, to throw the jack alternately rearward and frontward.

Referring to Fig. 6, the jack fulcrum shaft 158 is shown as provided with a sleeve 205 having a leftward extending rock arm and roll 206. The sleeve 205 is connected to the shaft by a spline 207, so that, when the cam roll 206 is actuated, the shaft, and therefore the jack, are swung bodily, while up and down sleeve adjustments are permitted.

In order to throw the cam roll 206 first .one way and then the other to alternately in one of which it will throw the roll forwardly and in the other rearwardly. The wedge cam for convenience is the shape of an arrowhead, having the inclined cam faces,

beneath which are shoulders, and there being falls with the pedal 185 and the hold-down mechanism.

The wedge cam 208 could be thrown by hand from one position to the other. Whenever it is thrown, it results that the next lifting movement of the block 210 will cause the cam to act upon the roll 206 to reverse the jack position. The wedge cam might be thrown before the lasting of every shoe, so as to permit the lasting of first one right shoe, and then one left shoe, and so on; or it might be thrown for every second operation, so that, after a left and right shoe have been lasted, the next pair could be lasted first right and then left, and the third pair first left and then right, and so forth.

Obviously the degree of throw of the ack caused by the cotiperation of the wedge cam 208 with the roll 206 will be constant in amount unless some means of adjustment or a yielding element be interposed. Without either, the cam might tend to throw the jack farther than permitted by the adjustable stops 200, before mentioned; I have provided means for adjusting the action of the cam 208 to conform with the adjustment of the jack stops 200. Referring to Figs. 6 and 8, an enlargement or block 212 is shown formed or securely fixed uponthe lower end of the fulcrum shaft 158. This block, and also the sleeve 205 above it, are provided with bosses which are in alinement. An adjusting shaft 213 extends through both bosses and is threaded where it engages the threaded interior of the boss on sleeve 205. A simple pin and groove device prevents vertical movement through the other boss. When the hand-wheel 214 upon the adjustin shaft 213 is turned, the sleeve 205 is li ed or lowered. In this way the height of the cam roll 206 is adjusted at will. Since the upward and downward movement of the wedge cam 208 is fixed in extent, it is clear from Fig. 10 that an alteration in the height of the cam roll will vary the action of the cam. The higher the cam roll is adjusted,

- the less effect the cam will have in throwto lower thecam roll 206, so that the wedge cam will have a correspondingly increased effect.

It has been above explained that the wedge cam 208 might be thrown or tilted to its reversed position prior to the lasting of each individual shoe, or less frequently. I have shown automatic means for relievlng the operator from attention to this detall. by shifting the wedge cam to its opposite position wlth each operation of the hold-down mechanism performed upon the change .of shoes.

The wedge cam is a very'light member and capable of being thrown across by a light blow beneath the shoulder at the side toward which the cam is tilted. To give such a light blow at one side or the other, a pair of light spring fingers-215 are provided,

so located that on thedepression of the pedal 185 and after the wedge cam has disengaged the cam roll, the lower side of the wedge cam is caused to strike against the spring finger 215 at that side, thus causing the light blow necessary to tilt the cam across to the other side.

For convenience the spring fingers are mounted on the block 212, which is fixed at the lower end of the fulcrum shaft 158. Moreover, by this arrangement, as will be clear from Fig. 9, the spring finger which'is to be operative, will stand properly beneath the wedge cam, while the other spring finger will be swung outwardly so as to be inoperative.

The heel wiping mechanism, whichis explained more in detail in said application No. 97 ,516, is sufficiently shown for the purpose hereof in Figs. 1, 3, 4, 5, and 6', and may be partly described as follows.

At the right end of the machine base is a rising and falling support 218 similar to the support 23, which carries the toe wiping mechanism up and down. The support 218 is lifted or depressed by a crank 219. The support at its top carries 'a longitudinally sliding frame 223, which may be moved bodily toward and from the shoe by a handwheel 225, adapted to be locked when the parts are in wiping position by a lock device 226.

j The sliding frame 223 supports above it a transversely swinging carriage 228, upon which the wiping devices are carried. This carriage is movable transversely upon curved guides 229, which are in the form of arcs struck about the apex of the heel wiper plate contour as a center.

Bv this arrangement one is permitted to adjust the jack to the required incline to cooperate, as before described, with the toe wiping mechanism, during which the apex L of the heel of the shoe remains substantially stationary on account of its proximity to the center D, about which the jack swings, (see Fig. 11). It is, therefore, merely necessary to swing theheel wiper plates about their own apex to adapt them to any adjustment of the jack and shoe.

While this adjustment might be performed by hand and determined by eye, there is herein disclosed an automatic arrangement for determining or effecting the swinging adjustment of the carriage 228, according to the position of thejack. The

carriage shown provided with a depending stud or roller 230 engaging a guiding extension or tail, which is seen as extending rigidly from the right of the jack. This guiding extension is formed with side walls 232, between which is a groove engaged by the stud 230. The groove has a flaring en-- trance, so that, when the. studis retracted, it will readily find its position again in the groove.

When the sliding frame 223 and the wip ing head are retracted, the-stud: 230 may stand tothe right of the guiding extension.

In this position the jack may be adjusted for changes in shoe style. Upon bringing the wiping head toward the shoe, the operator is relieved. from the need of determining the position of the swinging carriage or the line of wiping action, since the engagement of the stud and guiding extension automatically determine that. Further, when the jack is thrown symmetrically across from one side to the other in changing from rights to lofts, and vice versa', the swinging carriage 228 isqcause'd to correspondingly swing in the reverse direction. Thus, the actionof the pedal in unclamping one shoe and clamp- ,ing the next automatically determines or effects the-position of the heel wiping head.

This is important additionally because mini-' mizing the diliiculty of resetting the machine in changing over from rights to lefts,

' thus tending to render practical the plan of lasting the right and. left shoes of a pair before lasting otherpa-irs. y

Above the swinging carriage 228 are opposite brackets 234 having trunnion bearings 235 at the top, between which are supported a longitudinally tilting shell 237, in-

side of which is contained a laterally tilting barriage 240. The wiperplates 270 and,

their actuating mechanism,including the operating handle 280, are all mounted on the carriage 240, and therefore partake of the lateral tilting movements of that carriage.

and the longitudinal tilting movements of the shell 237 and the swinginlgemovements of the carriage 23 i. -As descri d insaid application No. 97 ,516, it is proposed that,

when the-jack is reversed in position, or

when the carriage 234 is correspondingly re versed, one or both of these actions will effeet the symmetrical reversal of the lateral tilt of the wiping plates and .the carriage 240 supporting them. The details of the connections by which the operating handle 280 moves the wiper plates toward and from the shoe, and causes them at the'same time to swing toward and from each other, are

better shown and described in said applicationNo. 97,516.

The operation of the above described lasting machine may be as follows: The shoe containing the last will first be engaged upon the heel rest, and then moved toward the left until snugly seated on the toe rest. If there has been a change in the shoe style operated upon, the jack will be swung transversely to a slight degree until the shoe toe apex is brought into the longitudinal axis, or. in alinement with the shoe heel apex. During this setting of the jack the toe wiping mechanism will have been brought approximately into position, so that the wiper plates may serve as a gage in adjusting the shoe and jack. It will be understood that during this adjustment the symmetrical stops for the jack will be properly readjusted to correspond with the new position of the jack. As soon as the operator is satisfied that the shoe is lying in the proper positionthe pedal 185 will be completely de pressed, this applying the hold-down clamps torfirmly' press and hold the shoe upon the jack, and at the same'time locking the heel rest against sliding and locking the jack against swinging. The pedal is held locked in its depressed position, and the operator may remove his foot. The heel wiping head to the position of the shoe. After the proper adjustment of-the longitudinal and lateral tilt of the wiper plates, the hand lever will be worked to perform the wiping operation. The in-turned margins of the upper will be tacked or otherwise secured at the completion of the heel wiping operation. The

heel wiping mechanism may be left in contact with the shoe for the toe wiping operation, although the described hold-down is sufliciently efi'ective and rigid to dispense with the need of additional backing up of the work. The toe wiping mechanism will be set accurately as to the angle of wiping action, if not already set, and, after'adjust- -ment of the lateral and longitudinal tilt, the

hand lever. will be worked in conjunction with the lifting pedal to perform the wiping in the usual manner. The wiped-in margins will be secured. Both wiping heads may be retracted from the shoe. The 'hold down pedal will-now be unlocked and allowed to rise under the influence of its spring. This causes the hold-down hooks to lift and separate, so that the shoe may be retracted. Also the lifting of the pedal symmetrically reverses the jack from one incline to the reverse, the laterally tilting wedge cam having been reversed in position'fupon the previous downward movement of the pedal. The shoe is now removed and its mate inserted. The

jack having been already set, the hold-down clamps are applied by the depression of the pedal, which, as before, becomes locked preparatory to the wiping operations. The depression of the pedal, as before, reverses the tilting wedge cam, so that, on the next rise of the pedal, the jack will be thrown transversely across to resume its first position.

It will thus be seen that I have described a lasting machine and wiping mechanism embodying the novel principles of the present invention and attaining the objects and advantages thereof; and further advantages in the described structure will be apparent to those skilled in the art. Many matters of mere design, arrangement, detail or sub-combination may be variously modified without departing from the underlying principles of the invention, and, therefore, there is no intention to limit the features excepting in so far as the same are recited in the appended claims.
