utility of the present invention are not innism shown in my prior Patent No. 1,260,033,

Be it known that I, A GE O PERBI, aciti- Zen of the United States, residingat Watertown, in the countyof Middlesex and: State of li lassachusetts, have invented anew and useful l/Viping Mechanism, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention is a novel wiping. mechanism. This application and patent is acompanion case to my copending case entitled Shoe lasting machine, filed August14 .1919,

Serial No. 317,498. Said copending. case discloses a complete machine embodying pulling-over mechanism, toe wiping mechanism, heel wiping, mechanism and a shoe holding device .orjack :shiftable so as to change the shoe position after the pullingover to place it advantageously to co-oper ate with the wiping mechanisms. The pres- ,ent case'has reference more. particularly to; the toe wlping mechanism, which is only generally indicated in said copending case. It isto be'understood that; .wlule the wiping mechanism of the present case 1s designed and adapted more particularly to the wiping of toe ends of shoes, many features might,

be :used in wiping mechanisms for the heel ends; also the mechanism hereof would be useful, not merely ,in a complete pullingover and wiping machine, as in said copending case, butalso in other forms-of lasting machines, for-example, the well known bed laster, in which no pullingeover, but only wiping, is performed; and the scope and tended to be restricted in these respects.

The main object }of the present invention is to afford a shoe wiping mechanism operating; in amore eflicient-and convenient manner, and with better results in the product,

as-compared, for example, with the .mecha- ,nism generallyshow'n in'm'y prior Patent No. 1,260,034, patented M arch 19, 1918. An-

other object is to afford an improved con-v ,struction for readily bringing. about the re- ,.versal of the contour of the Wiping plates, so as (to. quickly readapt the machine for right and left shoes, respectively, this being in a way an improvement over themechapatented March 19, 1918. Another object is VTIPING Specification of Letters Eatent. Pgttentfl' June 19,22.

Application filed August 14 ,219.19. Serial No. 317,569. i

Other and more particular objects and advantages of the. present invention will be ,made clear in the hereinafter following description ,of an embodiment, thereof, or will be apparent to those skilled in the art.

To the attainment .of the above mentioned objects, the present invention consists in the novel machine, mechanism, combinations, devices and arrangements herein illustrated, described or claimed.

Fig. 8 is a similar View with the parts readjustedor reversed to give the proper contour for a left shoe.

extreme left. The plates and theirfittings' are mounted on a carrier or first carriage 20, which is cylindrical and is slidably fitted within a second carriage or trunnioned shell 21. This is arranged to tilt longitudinally to give the adjustment in that respect to the wiping plates, and is fnlcrumed upon the succeeding carriage 22, which is of a rotary nature for the purpose of alterlng the direction of wiping action in reversing the machine for right. and left shoes. The base of the rotating carriage 22 rests flatly upon the top surface of a transversely swinging carriage 23, the shifting of which also takes part in reversing the machine for right and left shoes. The carriage 23 is pivoted at its left end to a transversely sliding carriage 24L beneath it, this in turn being dovetailed at the top of what may be termed the base carriage 25.

The fittings below this point are not herein shown and per se form no part of the present invention,but can be ascertained from Fig. 1 of said copending case, where it will be seen that the base carriage 25 is mounted to slide vertically on an upstanding post, fulcrumed at the base of the machine. A. wiping pedal is provided, so that during the wipingaction the operator can lift and lower the entire wiping head, as is required, this being necessary to be done in conjunction with the actual wiping movements effected by the handle '18 before mentioned;

Also the upright post which supports the base carriage is capable of bodily swinging toward. and from the shoe, so as to carry the wiping mechanism conveniently into and from operative position, and when advanced and set in operative position the post is further adjustable toward and from the shoe as desired. by a screw adjusting device These parts omitted herefrom are substantially also disclosed at the lower left side of Fig. 1 of my prior Patent No. 1,260,034.

The dovetail connection of transversely sliding carriage 24 upon the base carriage is well shown in 1 and 6; This sliding takes place upon the reversal of the machine for rights and lefts. Stops are rovided to limit the extent of sliding. For example, at the front side a stop screw 27 is shown, rotatively secured to sliding carriage 24. Beneath it a bracket 26 stands out forwardly from carriage 25. Symmetrical stops 28, 28 are shifted together or apart by the right and left threads of screw 27. Upstanding from the bracket is a block or central stop 29, between the stops 28' and through which screw 27 loosely passes.

l Vhen the carriage 24L is slid back or front from the neutral position shown, one or the other of stops 28 contacts stop 29 and determines the position of the carriage.

The carriage 23 will be thrown acrossthe machine and back by the reversing handle 4-0, afterwards to be described.

The transversely swinging carriage 23 is fulcrumed at 30 to the carriage 24;, so that the free or right end of the carriage 23 may swing rearwardly and frontwardly. The rotary carriage 22 in turn is centrally fulcrumed at the right or free end of swinging carriage 23. The following contrivance is employed to automatically rotate the carriage 22 when the carriage 23 is swung across the machine. Carriage 22, which is disc-like, is provided with a curved rack 31, engaging the large-radius portion 32 of a toothed member mounted on the carriage 23, the small-radius portion 33 of which in turn engages a pinion 34 mounted on the stud 30 before mentioned. at the upper side of the carriage 23. The pinion 34 is held against free rotation, either by being fast on the stud 30. or in the alternative manner which will be described. By this arrangement, when the carriage is swung the toothed member travels around the pinion causing its rotation and in turn the rotation of the carriage 22. It may be desired to rotate the carriage 22 to a greater extent in order to secure the desired angle of wipingaction. To this end, the pinion 3a is rotatable by the following means. It is shown meshing with a pair of sliding racks 35 guided in portions of the carriage 23 and having downward studs or ofisets at their right ends adapted to engage with cams 36 mounted upon the underlying carriage 24.

By this, when the carriage 23 is swung one or the other of-the cams 36, acting on its rack 35, will slightly shift the rack causing rotation of the pinion 34- and increased rotation of carriage 22. The described parts, on carriage 23, will be covered over for protection, the cover being omitted in Figs. 9 and 10 but shown in Figs. 1, 2, 5 and 6.

carriage 23 'swin s, and attached on top' of y, this rim 1s a holc -down or bearing plate 38,

extending over and securely holding in position the rim of the rotary carriage 22,'as

clearly seen in Fig. 6. The top' side of thefiat concentric hold-down plate 38 serves.

also asa sliding surface or bearing for certain parts to be descrlbed, which run along its top.

This handleis/so connected as to perform several functions, namely, first to unlock and reverse the contour of the wiping plates themselves, all of which will be later described,- and thereupon to effect the described reversals of the three carriages 24, 23, 22, which action will now be described. Referring to Fig. 3, a link 41 is shown, extending forwardly from the reversing lever. This is slotted at 42, giving a certain amount of idle motion or play of the lever before the reversing takes place.

- A threaded rod 48 loosely rotates within the bearing in the block 47, but is prevented by a pinand slot, as seen in Fig. 6, from endwise play. The threaded rod'or screw shaft 48 has righthand'threads at its rear and lefthand threads at its front part, and beyond these threads the rod is journaled in bearings or brackets 49," extending upwardly and rightwardly from the swinging carriage. Upon a forward extension of the rod is a hand wheel '50, by which the rod maybe turned for symmetrically adjusting toward and from each other a pair of blocks 51, 51,

' engaged on the rod at either side of the central block 47. These blocks constitute stops or positioning membersfor determining the forward and rearward throw of the swing- This is to give time for the lever to. preliminarily unlock, reverseand relock the 'ment with athreaded rod 66;having a hand rod 66 engages the half-nut in its threaded carriage. viiiach of the blacks 51, and

As before stated, the rotaryicarriage 22 has upstanding bracket portions, at the top of which is trunnioned the hollow shell or tilting carriage 21. Forthe purpose of adjusting the longitudinal tilt, the adjusting wheel 60-is shown, the hub of this having a threaded recess with right and left threads engaging corresponding screws connected respectively to the carriage 22 and the care riage 21. The lateral tilt may be effected by 'the following. By means of aikey 62, a later'al tilting handle 63 is slidingly engaged with the cylindrical carriage 20 within the hollow shell 21, see Fig. 6. The hub portion of the handle surrounds the carriage and extends upwardly within convenient reach. A latch lever 64 holds it in desired adjustjment, but by {pressing this lever, the tilting lever 63 may be thrown forwardly or rearwardly. When seta'nd released a'springpressed half-nut 651s brought lnto engage-- wheel 67 at its forward end, so that by turning the hand wheel a finer adjustment of'tilt .inay be effected, after thetilt has been'a'pproximately attainedby the hahdle63. The

. tion on the hollow shell 21. 'a swivel connection 71 with the rear end of the wiper carrier 20. Thereby throwing plate. ably by rotation in a horizontal plane about portion, while its far end is swivelledon an the handle 18 to right or left advances or retracts the carrier or wiper plates. When the wiping plates have been advanced and the wiping is completed, the parts may be locked in such position by means of toothed rack 72, mounted on the hollow shell 21 and engaged by the extremity of a latch lever 73, pivoted upon the main wiping lever 18. Depressing the latch lever frees the wiping lever for action.

The wiper plates are mounted to the right of the wiper carrier 20. Each wiper plate is reversible in position and has two contours, one for right shoes, one for left shoes. Thus, in Fig. 7, the plates are shown set for a right shoe, the rear plate having a contour 88 contiguous to the contour 84 of the front Each of the plates reverses preferan axis within the body of the plate, and at the opposite side to the right shoe contour each plate has a left shoe contour 81 and 82, respectively, which in Fig. 8 are shown matched up ready for operation on left shoes. I will first describe the action and mechanism for giving wiping movements to the plate, and afterwards the means for reversing them for right and left shoes. Each plate is mounted at its pivot or center 85, above an arc-shaped block or segment 86, having a dove-tail connection 87 upon the enlarged extension or head 88 of the carrier 20. The segments 86 are really curved slides capable of being moved toward and from the shoe by a curved motion about a center sub stantially at the center of the apex of the shoe toe. The contiguous corners of the two wiper plates meet at its center or apex, and therefore the wiping movements of the plates take place without at any time breaking the continuity of the wiping edge.

For causing the wiping movements of the lates, each sliding segment 86 is providedwith a toothed rack 90 engaged by a pinion 91 mounted loosely on a stud upstanding from the carrier head 88. Attached to each pinion 91 is a lower and smaller pinion 92,

engaged by a longitudinal toothed rack 93, secured against movement with the carrier,

by being mounted on a vertical rod 94c.

These parts are shown in Fig. 7,'and in Fig.

The handle has a portion ofthe shell 21' and capable of rotating thereon to accommodate itself to the tilt of the wiping mechanism, but incapable of longitudinal motion with the wiper carrier.

The result of the described eonnections' is that, when the wiper carrier 20 is thrust forwardly relatively to the shell and the vertical rods 94:, the racks 93, remaining stationary, cause the rotation of the pinions 92 and 91, and thereby the concentric swinging apart of the segment slides 86 and swinging together of the wiper plates.

When in either position, namely, for right shoe or left shoe, the wiper plates are looked, as shown in Figs. 7 and 8, by lock pins 99, spring-pressed upwardly into circular recesses at diametrical points on each plate.

Before the plates can be reversed, the locking pins must be depressed, and I prefer to do this automatically An unlocking lever 100, best shown in Fig. 1, is pivoted to the carrier head. It has its right extremity in engagement with the locking pins. It is understood that there is an unlocking lever at each side. The vertical rods 94, previously mentioned, are provided with pins 101, engaging the yoke left ends of the unlocking levers. By this arrangement the rip-pulling of the pins 94 will unlock the wiper plates to permit their reversal. This does, not affect the function of the rods 91-, as holders for the racks 92 before mentioned, as the rods slide freely vertically through the racks,

In order to simultaneously lift both of the rods 9 1-, I provide a reverser slide 103, mounted to be movable to right and left on top of the shell 21 by means of guides 10a 7 on the latter. The reverser slide is slotted at to accommodate a stop pin 106, which limits its advancing and retracting movement. The slide is movable directly beneath the cross rod 107, which extends from side to side and connects the upper ends of the two vertical rods 94:. The slide, in order to lift the cross rod and the vertical rods to unlock the wipers, is provided with a cam, comprising, first, the rip-slanting surface 108, followed by the dwell or horizontal surface 109, and then a down slant 110. In Fig. 1 the slide 103 is moved slightly to the left, the rod 107 is lifted to the dwell 109, and thus unlocks the wiper plates, which may then be reversed, after which the continued leftward movement of the slide would let the rod 107 ride down the incline 110 torelock the plates. I prefer that the same member or slide 103, which thus unlocks and relocks the plates, shall also reverse them for right and left shoes. For this purpose the extreme right end ofthe reverser slide has a pair of downward arms 111 at front and rear. The lower parts of these arms have outward flanges, 112 at the right, 113 at the left. It will be understood that this entire system is moved to right antl left from the reversing slide. Figs. 7 and '8' show the relatlve'posltion of the depending arms 111 and the reversing mechanism. Between the flanges 1'12 and 11 3'en'gages the hooked end of a' small lever 1 15, mounted on a sliding rack 116, which in turn is mounted on the segment 86 which carries the wiper plates. The" rack is'm engagement-with a p1I11QI1'1l7,

"which in turn engages a pinion 118, concenof little upstanding. pins 119 at either sideo'f the pivot 85.

It is now obvious'that, if the reverser slide and the flanged arms 111 be retracted from the Fig. 7 position tothe Fig. 8 position, this will retractthe rack 116 and rotate'the pinion to swing the two wiper plates through a half rotation from the Fig. 7 to the Fig. 8 position. The reverser slide, therefore, when thrust to the left, first unlocks the wiper plates, then reverses them, and then looks them. The hooked lever I15 rides idly be tween the flanges 112, 113, during the locking and unlocking-and the reversing is performed while the dwell portion 109 of the reverser cam is in effect.-

I The wiper plates are shown uncovered, in Figs. 7 and 8, butin practice'they are covered, for example, by the pivoted cover plate 120, which may be swung up for interchanging the plates, but when swung down is secured in position by a screw device 121.

It has been be'forestated that I preferto unlock and reversethe wiper plates in the same action or by the same part as the reversal of the carriages 24 23 and 22 in changin the machine for right and left shoes alternately. Therefore I will now de-,

scribe connections from the reversing lever 10 to the reverser slide 103. Engaging an upstanding studon the vreverser slide isa rock arm122, seefl ig. 5. This is connected. at the upper end' of a rock shaft 123. This rock sha'ftis sectional, having a universal joint 124, sufiiciently indicated in Figs. .1 and 6, and at its lower end the rock shaft has a rock arm 125, from which extend s-rcarwartlly 'a-link 126 to a floating arm 1 27,"piv

oted at one side of the reversing lever 40. H p I v wherein 1s a means foroppositel-y and slmul- This permits a yieldingconnection between the reversin lever and the reverser slide. Theupper end o'fthe arm 127 is yoked" at 128, and springs 1'29, extending across the yoke, engage a block 130, mounted on the lever 40'. c v

The result of these control connections is that, when the reversingrlever 4:0 is thrown, it first acts to shift the reverser slide, and thereby unlock and reverse the wiper plates. The springs 129 are'quitestrong an'ddo not yield materially. During this action the What iS-eeimea is: l p In' a lasting machine slot e2 prevents reversing movement of the carrlages. After the wiper plates' h'ave' been reversed, as described, the reversing lever takes effect to reverse the carriages, and? I during this 'motionthe springs 129 yield si'iificientl'y to avoid obstruc'tingthe proper swing of the 'reversing lever. A convenient device to'present'wiretothe shoe for securing'the' wiped edges before't'h'e removal of the shoe may be as follows.
