Specification of Letters Patent.

Patented Apr. 16 1191?.

' To all whom it may concern Be it known that I, ANGELO .PERRI, a citizen of the United States, residlng at Groveland, in the county of Essex and State of .Massachusetts, have invented certain new and useful Improvements in Lasting-Machines, of which the following is a specification, reference being had theremto the step in the manufacture of shoes.

prise the steps offirst--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 curedpreparatory' 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 pertains more espe cially to a wiping mechanism adapted to use at the toe end of the shoe, although various features hereof might be effectively otherwise employed;'and the principal object of the present improvement is to afiord I a wipingmechanism which will be simple and durable in construction, and eflicient and convenient in operation.

The present application, therefore, discloses one form or illustration of a toe wiping mechanism embodying the present invention. It maybe ;variously employedserted after having been" pulled-over and in which usually both the. heel and toe portions of the shoe upper are wipedand secured. On the other hand, the mechanism hereof may be substituted in such a machine as that of said Patent N 0. 1,168,963 for the toe wiping mechanism there shown. Or the mechanism hereof might, in some cases, it

desirable, be employed by itself solely for the Wiping of toes of shoes.

The toe wiping mechanism herein illustrated is shown for convenience of such design as to be particularly adapted to employment in a bed lasting machine, and for this purpose to be combined with a jack or work holder which properly holds the shoes, and a heel lasting or Wiping mechanism arranged in suitable relation thereto. The jack and the heel wiping mechanism, which I have designed to coiiperate with the. toe wiping mechanism hereof, are not shown in detail or claimed herein, but are thesubjects'of separate patent applications, Serial Numbers 96,748 and 97,516. I

Among the particular objects to which the present invention is directed is to provide a toe wiping mechanism adapted to eflicient and convenient use for the wiping of both shoes, that is, the right and left shoes of a pair. A mechanism which is quickly re-.

versible for this purpose is very advantageous as permitting the operator to complete his work on both shoes of a pair before operating upon other shoes. It is very desirable that a wiping mechanism shall be free from the necessity of separate adjusting' operations to adapt it for the right and left shoes of a pair. Ordinarily separate wiping plates or blades have been used for the two shoes of a pair, and it is an aim hereof to provide that a single set ofw iping plates serves both for the right and the left that. a single set of wiping plates may be simply inverted to convert them for use on the other shoe of a pair. By'such improvement the adjustment of the plates for one shoe dispenses with any further adjustment for the other shoe, and symmetry in the two shoes is insured.- I also propose the plan of employing movable, or retractible,

or repressible, reinforcing parts for the wiping plates, and, by arranging such reinforcing parts both above and below, great strength and durability are secured while permitting the one'set of plates, which are of comparatively light construction, to be shoe. It is a plan and object to so arrange 3 effectively employed with either side upperstitute parts and objects of the present invention, and further objects and advantages of the mechanism hereof will be elucidated in the hereinafter following description or will be apparent to those skilled in the art.

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, combination and detail herein illustrated or described and claimed.

The accompanying seven sheets of drawings contain the following figures:

Figure 1 is what may be considered a front elevation of a lasting machine or wiping mechanism embodying the present invention, the wiping plates standing at the extreme right and the shoe being supposed to be held to the right thereof in inverted position and with the toe directed leftward toward the illustrated wiping mechanism. The jack, which is supposed to hold the shoe in this position, and the heel Wiping mechanism, which would stand to the right beyond the jack, arefor convenience omitted from this figure, as well as certain underlying supporting parts.

Fig. 2 is a right elevation of the mechanism shown in Fig. 1.

Fig. 3 similarly is a left elevation of the mechanism shown in Figs. 1 and 2.

Fig. 4 is a top plan view thereof. Fig. 5 is a plan View of certain parts shown on a smaller scale.

Fig. 6 is a central vertical section on the plane '66 of Figs. 2, 3 or 4.

Fig. 7 is a plan view similar to Fig. 4, but with many of the upper portions of the machine omitted, and further details indicated. Fig. 8 is a plan partly in section taken on the plane 88 of Fig. 1. Fig. 9 is a top plan view of one of the movable reinforcing parts or guards detached. Fig. 10 is a top plan View of one of the segments or carriers of the wiper plates. Fig. 11 is a section on the plane 1111 of Figs. 7 and 8. Fig. 12 is a similar section showing the position of the parts during the wiping operation.

Fig. 13 is a general front elevation showing a suitable arrangement of base parts and mechanisms in a bed lasting machine. This corresponds to Fig. 1 of each of said two other separate patent applications.

Generally speaking, there may be a base 19 on which is supported a suitable shoe holder or jack 21, and to the right of the jack, a heel wiping mechanism 22, and to the left of the jack the toe wiping mecha nism 20. A support 23 may be connected to the base to be lifted and lowered by a pedal 24, as is required in the usual wiping operations. The toe wiping mechanism is carried on a carriage 25, which may be longitudinally slidable on the liftable support 23 by means of a dovetail engagement. Sliding may be effected by the turning of hand wheel 26 fixed on a threaded shaft mounted in the support and engagingin a threaded depending lug 27 of the carriage for the purpose of bodily adjusting the wiping mechanism toward and from the shoe position.

At the near and far sides of the carriage are a pair of upstanding brackets 30, and these at their upper ends carry between them the entire toe wiping mechanism 20 hereof, which as a whole is conveniently termed the head.

It will be convenient to outline at this point the usual or necessary motions, adjustments or operations involved in toe-wiping, and afterward take up the different parts of the mechanism for effecting or enabling the desired results.

One movement is the longitudinal adjustment of the entire toe wiping mechanism and the carriage 25 toward and from the location of the shoe A, this being efiected by the hand wheel 26 before mentioned.

Another movement is the raising and lowering of the wiping mechanism during and as a part of the wiping operations, this being effected, as before stated, by the pedal 24 acting on the support 23.

A longitudinal tilting adjustment of the entire wiping mechanism is necessary to properly set the wiping plates to operate upon different styles of shoes. This adjust-' ment may be effected by swinging the entire wiping head about trunnions 31 provided at the top of the carrying brackets 30, and the amount oftilt may be, for example, that indicated in Fig. 1 by the broken lines BB and C,C.

The operative wiping movements of the wiper plates, which are supposed to take place in conjunction with the lifting and lowering movements before mentioned and after all the true adjustments have been made, is shown herein as consisting of an operative advance of a pair of wiping plates accompanied by\ a swinging or converging movement during the advance, and the retreating movements of the plates being accompanied by a separation or a swinging apart movement or divergence thereof.

The more important features of the invention hereof pertain not so much to the above enumerated movements and adjustments as to the further features of adjustment now to be enumerated.

Where the contour of tos differs extenreplaced by another pair or set of the proper contour, the interchange is complete and no further interchange is necessary for the mate, since, according to this invention, the

same set of plates is made to serve for wiping both the right and left shoes of a pair. The movement or shifting or adjustment of the single set of plates to adopt it from one to the other shoe, consists herein substantially in an inversion thereof. The two shoes of a pair are always symmetrical and,

A. very desirable change in adapting the machine for the other shoe of a pair con-- sists in an alteration of the line of action or advance of the wiping mechanism. Shoes with variations of styles.

. axis so as to properly face the shoe.- This alteration is shown as performed herein by a bodily shifting adjustment of the wiping plates and their operating mechanism, and the change may be accompanied by a slight swinging of the shoe A about a suitable center or vertical axis D provided on the jack. This adjustment is so provided in the present invention that when the proper angle or swing has been determined and secured for one shoe of a pair theact of in.-

verting the wiping mechanism for the othershoe automatically reverses to the proper degree the line of action or operation of the wiping plates, thereby utilizin and preserv ing the adjustment already e ected and dispensing with a new adjustment for the second shoeof each pair. This matter is generally indicated in Fig. 5 in which the full.

lines indicate the wiping mechanism set'to the proper line of operation for a left shoe,

the shoe also shown in full lines, and indicating also in dotted lines the inverted position of the wiping mechanism in which it is adapted for the mate or right shoe, shown also in dotted lines, the shoe swinging about the vertical axis D provided on the jack, for example, just to the rear or near the extremity of the heel.

Another necessary adjustment is the lateral tilting of the wiping mechanism to ac-' cord with different shapes of shoes. Thus in This in- Fig. 2, while, for convenience, the parts are shown in a normal or untilted position, a

broken line EE has been added showing a suitable amount of lateral tilt to accommodate the plates to shoes presenting such tilt at the toe portion. Whatever tilt'is secured by adjustment for one shoe of a pair must be reversed for the other shoe, and it is a art of this invention that the mere inversion of the wiping mechanism as before recited to change the same from right to left shoe, and vice versa, is automatic and without further attention accomplishes the reversing of the lateral tilt.

I have, therefore, provided a very advantageous machine or combination wherein merely a single set or pair of wiping plates is required to be interchanged for a difierently shaped set or pair when a change occurs in the contour of the shoes to be last-- ed, and in which .the mere inversion of such set of wiper plates serves not only to symmetrically reverse the contour thereof. to adapt them for the other shoe of a pair, but simultaneously, and without attention from the operator, reverses also the line of wiping action, and also the lateral tilt of the wiping plane necessary in changingrover from one to the other sho'e of a pair. hus, a single and quickly performed adjusting movement automaticallyeifects three readjustments and completely changes the machine over from rights to lefts, and vice versa. The ease, exactness and efficiency of such changing over from rights to lefts, and

vice versa, renders it practical to performthe lasting of shoes in the'manner before recited, namely, by completing the lasting of each pair before proceeding. with the lasting of other shoes. The absence of numerous laborious and cumbersome readjusting operations gives this desirable result and tends to render more available commercially a class of machine which, at best, has but slightly advanced-the art overthe practiceof lasting by mere appliances.

It is true that some manufacturers have largely adopted lasting machines but at a certain sacrifice in perfection of output and where they have been willing to permit the lasting to be performed by operating first upon a great number of right 'shoes and then upon a great number of left shoes. The last mentioned mode of manufacture is replete with objections which are overcome by the present invention. The pulling-over of shoes is properly and effectively done only when the two shoes of a pair are attended to in immediate succession, and this is the usual practice. The leather constituting the upper has to be steamed for the pulling-over and wiping operations to render it soft and pliable, and it is very desirable that the two shoes of a pair in this soft steamed condition should, after the pulling-over, -be immedimore easily done when the operator takes them up in immediate sequence.

The bodily longitudinal adjustment of the toe wiping mechanism toward and from the shoe and its lifting and lowering being understood need not be further mentioned. The interchange of wiping plates for others of different contour is to be understood and need not be further mentioned excepting to state that in certain cases the contour of plates might be somewhat altered without detachment. and replacement, for example, by adjustment. There remains to describe the operating movements or the advance and retraction of the wiper device or plates, the adjustment of the angle or direction of action, the adjustment of the longitudinal tilt, the adjustment of the lateral tilt, and the inversion of the wiper device which auto matically and symmetrically reverses the contour in changing over from rights to lefts and at the same time symmetrically reverses the angle or direction of action and the lateral tilt previously determined.

Generally speaking, the trunnions 31 at the top of the brackets 30 support a ringshaped bearing which is hung between them so as to swing about a transverse horizontal axis to permit adjustment of longitudinal tilt. A flanged member or shell engages the bearing ring, and is capable of revolution therein for bodily inverting the wiper 0r wiping plates and associated parts. This shell in turn is provided with transverse ways or guides struck upon an arc with the -tip or apex of the retracted wiper contour as a center. A laterally shifting carriage is mounted to slide circularly upon the arcshaped guides. In turn this transverse carriage contains at the center of the system a longitudinally sliding carrier, at the forward end of which are carried the wiper plates and the means for causing them to approach each other as the longitudinal carrier advances. This general arrangement being understood, I will now describe the details of the fittings referred to, and will then explain the various modes of adjustment and movement involved and the results and operations permitted thereby.

"Beginning with the trunnion bearings 3 at the top of the brackets the connections therefrom to the actual wiping plates 60, 61, may for convenience, be as follows, to secure the objects mentioned.

A bearing ring 32 is pivoted or hung between the trunnions 31, this ring being formed in two vertical halves secured together at the top and bottom by bolts 33. The bearing ring 32 incloses a revoluble member or shell 34 which is double flanged to embrace the ring 32, as clearly seen in Fig. 6. The shell 34 is formed in separable upper and lower halves for facility of assembling. This shell carries within it a large part of the mechanism to be described, all of which revolves with the shell when the latter is inverted, as will be described. Some of the mechanism to be described, however, is not revoluble with the shell but is otherwise mounted, for example, on the bearing ring 32. This refers to the manipulating and adjusting levers and parts which retain their position during inverting operations.

The longitudinal tilting adjustment of the entire wiping mechanism or head may, for convenience, be performed bya manipulating part such as hand wheel 36, see Figs. 1 and 2, having connections by which the bearing ring 32 is tipped or slightly swun about the horizontal axis aflorded by the vtrunnions. The hand wheel is fixed upon a short shaft which is connected by engaging bevel pinions 37, 37 with a worm 38, see also Figs. 3 and 6, the worm engaging a longitudinally arranged rack 39 secured to the bearing ring 32 for convenience by insertion between the bolted-together halves of the ring. Turning the hand wheel 36 quickly alters the longitudinal tilt to the extent desired, for example, as indicated by the broken line B,B, Fig. 1.

I will now describe the fittings by which the revoluble shell 34 has the lateral shiftable carriage 45 connected to it. The shell is shown provided with transverse cross bars 41, 41 upon which bearing plates 42, 42 are permanently screwed. These bearing plates are parallel and face each other, providing space between in which the transverse carriage moves. Each bearing plate 42 is provided with an arc-shaped way or track 43.- The carriage '45 is provided with upper and lower plate- like extensions 46, 46, bearing against the, plates 42, and each extension 46 is provided with a rib or tongue which is arc-shaped and slidingly engages in the grooves or ways '43 formed in the bearing plates 42. The carriage 45 comprises not only the two flat portions 46, but also a circular or barrel-shaped portion 48 containing within it certain mechanism hereinafter to be described.

As will be seen from Fig. 7, the tongue and groove connection 43, 47 between the revoluble shell and the transverse carriage is in the form of an arc struck approximately from a center indicated at F which is the apex of the curve or. contour of the wiper plates. Bythis arrangement whatever change of adjustment is made as to the angle of action of the wiper plates the direction is always at. right angles to the contour of the shoe at the extreme tip thereof. The point F, as will further appear, is also herein shown as constituting the point of contiguity of the two wiping plates, which swing toward each other about said point during the advancing or operative movement thereof. By the described arrangement the adjustment of the angle of action about the point F gives a convenient and satisfactory coiiperation with a shoe holding device permitting the shoe, right or left, to be swung into position about an axis near the tip of the heel, as already described.

The carrier by which the wiping plates are put through their operative movements of advance toward the shoe and retreat, is

shown herein, see Figs. 1, 3 and 6, as a generally cylindrical member 50 inclosed within the hollow interior of the circular or barrel portion 48 of the transverse carriage 45. The carrier 50, for purposes of construction and assembling, is made in upper and lower halveswhich are axially hollowed out, ex-

cept at the foremost end, and each of the two' halves has secured to it a square bar or spline 51 engaging in a corresponding longitudinal recess in the transversecarriage'; This arrangement permits the carrier to he slid longitudinally within the carriage while at the same time it is compelled to partake of any revolution which may be imparted to thleucarriage and the surrounding revoluble s e The wiping plates themselves and certain associated mechanism,.including the devices to cause the plates to swing toward and from each other, are all mounted at the right hand end of the carrier so that any longitudinal movements given to the carrier are imparted to the wiping plates. The mecha- V or halves, the upper half and-the lower half. I

in either of two positions, one inverted with respect to the other. As already stated, the carrier 50 is formed in two separate pieces The construction of the upper and lower halves is substantially the same. Each is Eff provided near its forward portion with an outwardly extending semicircular flange 53, which in Fig. 6 is shown abutting against the transverse carriage 45, the latter thereby forming a backstop limiting the sliding motion of the carrier.

As further seen in Fig. 6 and in plan view in Fig. 7 the carrier 50 extends forwardly of the flange 53, where it is enlarged or laterally extended in the form of transverse wings 54 and arc-shaped branches 55 at.

Besides the front elevation, Fig. l, and i the right elevation, Fig. 2, showing a view of the forward end of the wiper devices, we now refer more particularly to the longitudinal vertical section, Fig. 6, the plan views, Figs. 7 and 8, and the detail views, Figs. 9 to 12.

The wiping plates 60 and 61 hereof are fitted to move forwardly with theadvancing movement of the carrier 50, and at the same time, analogously to the toe wiping plates in said prior Patent 1,168,963, to

swing toward each other in such way as to maintain at all times a continuous wiping edge. This is accomplished by fittings which permit the plates to swing about the center F located in the wiping contour and at the tip or extremity of the curvature thereof.

Each'plate is swung in the arc of a circle with a center at the point F, and the mounting consists of large-diameter, annular bearings located at a substantial radius from the meeting point F of the plates, this construc- One of the wiping plates 60 is shown separately in Fig. 10 in association with the connected arc shaped oscillating carrier or segment. Each plate comprises the thin, bladelike edge portion 62, which is securely pinned within a central groove at the forward edge of a stock 63. This stock at its rear side is provided with a dovetail recess.

engaging a correspondingly shaped portion 66 of the oscillatingsegment 67 The stock 63 is provided with a pair of upstanding tongues or guide ribs 64, to be engaged by corresponding grooves in the relnforcing block to be hereinafter mentioned.

The oscillating segment 67 comprises the arc-shaped slide 68, which engages in a correspondingly shaped guide or groove in tion avoiding wear and looseness of action.

the carrier 50. The connections are indicated in Fig. 8, the groove in the carrier being formed between upstanding portions 69, 69, 69, 69. Fig. 8 shows that these fittings are similar for both of the wiping plates 60 and 61.

The actuating arrangements the oscillating segment 67 and the Wiping plates 60 and 61 to swing simultaneously with the advancing and retreating movements of the carrier are very simple, consisting, somewhat as in said prior Patent 1,168,963, of toothed racks 70 on the oscillating segments engaged by intermediate pinions 71, loosely mounted on the securing bolts 56, before mentioned, and engaging straight, lon itudinal racks 72 formed on bent brackets 3 secured rigidly, but adjustable, by bolt-and-slot devices 74 to the opposite sides of the transverse carriage 45. Obviously the forward movement of the carrier 50 relatively to the carriage 45 causes the pinions 71 to rotate counterclockwise, thus swinging the wiper plates 60, 61 toward each other.

For steadying the wiper device, that is, the two coiiperating wiper plates, each consisting of stock 63 and plate 62, I have provided above and below the same a rigid abutment 7 5 engaged by mortise and tenon, as clearly indicated in Figs. 7 and 11, with the forward end of the carrier 50, including the two curved branches thereof; and these abutments serve also as protecting cover pieces. The abutment pieces 75 are detachably held in position by means of upstanding lugs 76 thereon, engaged by spring-pressed hooks or latches 77 mounted on the carrier 50.

The actual supporting or backing up of the wiper plates is performed, not solely by the rigid fixed abutments 75, but by a device or blocks 80, which, as will be more fully explained, serve also as gages to assist the wiping operation. The block 80 which is above the wiping plane always constitutes the reinforcing means for firmly holding the wiping plates down against bending, deflection or injury; while that block 80 which is beneath is made to serve as a gage for determining the extent of wiping movement and at the same time as a resilient clamp for pressing the upper snugly in place against the last of the shoe. The upper and lower devices are similar in construction, and their difference in function resides merely in their relative location at the time of operation.

Instead of constituting each reinforcing or gaging device of a single member or block co-extensive with both of the wiping plates, I prefer to constitute it of two separate blocks 80, 80, one co-extensive with each wiping plate or 61. One of the blocks for causing 80 is shown detached in Fig. 9, and the two of them in proper position are shown assembled in Fig. 8, while Fig. 2 shows one of them in front elevation and Figs. 11 and 12 show them in vertical section on the plane 1111 of Fig. 8.

As seen in Figs. 6, 11 and 12, each block 80 is constructed with a body having parallel upper and lower sides slidin'gly engaging against the opposed faces of the wiping plate stock 63 and the abutment or cover piece 75, respectively. Forward of the body portion is the edge portion 81, having, as seen in Figs. 8 and 9, a contour corresponding with that of the wiper plate, and firmly and intimately contacting the wiperplate, as 'seen in Figs. 6 and 11, so that each wiper plate is normally snugly encompassed above and below by blanks 80.

To permit the resilient yielding or retracting movement of the underneath blocks 80, or rather, to permit them to be repressed during the wiping action, each of them is rendered movable or slidable with respect to its corresponding wiping plate, and for this purpose each block 80 is provided with guideways or grooves 82, as indicated in Fig. 9, adapted to engage the guide ribs or tongues 64 provided, as before mentioned, on the wiping plate stock portions 63. To maintain each block 80 normally in its advanced position, shown in Figs. 8 and 10, spring 83 is provided, this being arranged to press forwardly at the rear side of the block 80 and being, for convenience, inclosed in a barrel 84 permanently provided on the oscillating segment 67. The rear edge of each block 80 has an upward flange 85 engaging behind an internal shoulder in the abutment or cover piece 75 for the purpose of limiting and determining the normal forward movement or position of the block. The stop and shoulder are shown in contact in Fig. 11 and in the upper part of Fig. 12. Each block 80 is further provided with a notch 86 normally engaging a pin 87 standing up from the stock 63 to determine the forward movement or position of the .block.

The extent of retracting or repressing movement of each block is limited by the contact or stopping action of the edge part 81 of the block against the forward portion of the wiping plate stock 63, these two members being properly shaped to co6perate in this stopping function, as indicated in the lower part 0 Fig. 12.

Fig. 12 indicates the gaging and clamping functions of the underneath blocks 80. It is to be understood that the wiping plates are shaped not merely for the proper contour of the shoe operated upon, but of the proper width or extent of forward IO]C- tion from the stock. Thus, as seen 1n Fig. 12, the width of the wiping plates, in conlit) junction with the stopping action referred to, determines the extent or width of wiping movement over the last of the shoe. For instance, it is desirable to gage or limit the wiping action so that the upper willbe laid snugly against the upturned lip of the sole;

and the plates will not be able to strike or injure the lip or displace the sole from its proper position on the last. This improve-'1 ment renders unnecessary any care to prevent excessive wiping movement.

Fig. 12 also indicates the before-mentioned clamping action of the resiliently acting blocks 80. Throughout all wiping diiiicult may be the lasting of a given shoe,

each block 80 is always performing its function in tending and assisting to smoothly shape and press the upper into its final desired position. The springs are not so strong as to cause any possible injury to the upper, or to hold it against the incidental stretching motions involved in the wiping operation. It should be noted also that, like the wiping plates, the contour of the two blocks 80 of each pair is always substantially continuous, since their contiguous corners substantially meet at the point or center F about which the plates and blocks are swung in their converging movements. i It is to be understood that the wiping op-. eration includes an upward wiping movement against the toe of the inverted shoe for the purpose of smoothing thatout before the subsequent inward or advancing and converging wiping movement is performed to wipe and press and gather the over-extendround-edged, and capable of wiping mg margins 'of the upper about the sole.

The described upward wiping movement may involve both upward and downward movements in performing this difficult oper-. ation to the best advantage, and therefore there may be not only an upward, but a downward, deflecting strain on the wiping plates and 61. These plates; while comparatively thin, are not sharp-edged, but are motion in either direction. the

During vertical wiping motions it willbe noted that I the wiping-plates are reinforced, as indicated in Fig. 11, both aboveand below in the most effective manner, the underneath blocks 80 being in their advanced or reinforcing position until the subsequent hori- =zontal wiping movements are performed,'as indicated in Fig. 12,-whereupon the shoe.

bya

' For convemence,

itself performs the service of repressing the underneath blocks 80 to the extent that may be required.

A supplement to the above described wiping devices, which may sometimes be desirable, is a contrivance for locking in their forward position the blocks 80 which lie above the wiping plane, and, therefore, are to serve merely as reinforcers. A vertical sliding lock device 90 in the form of a bar with a button at each end is fitted for this purpose in the forward portion of the carrier 50, as best seen in Fig. 6 and in top view in Fig. 7. This lock bar is adapted to be moved by hand upwardly or downwardly by the buttons at the ends, and in either position is yieldingly held by one or the other of a pair of round-nosed spring pins 91 provided in suitable sockets in the carrier 50, and adapted to enter slight depressions in the bar. An arc-shaped extending portion 92 is provided at the forward side of the lock bar 90 midway of its length, as' seen in Figs. 6 and 8, and this is adapted to stand behind and embrace the rear edges of the reinforcing blocks 80, which at the time are uppermost, and thus prevent relative retraction thereof. Thus, in Fig. 6, the lock portion 92 stands behind the uppermost pair of reinforcing blocks 80, firmly lockingthem against any possible movement away from the wiper plate edges to be reinforced. The undermost blocks 80,however, are free to be repressed, being beneath the lock portion 92. Upon the inversion of the'wiping mechanism, the operator may shift the block endwise to reverse its function. By setting it in an intermediate position, 'both sets of plates 80 may be locked forwardly.

Having thus completely described the wiper devices at the forward end of the v longitudinal sliding carrier 50, I will decontrolling the degree of .j elevation of the wiping plates and the amount of pressure by which they bear downwardly, is accompanied by the manipulation of the controller or the lever which controls the longitudinal advancing and retreating and the converging movements of the plates, the operator by these means working the leather of the upper under his continuous inspection into the desired shape.

manipulation of the wiper plates may be in tilt of the wiping head, but, as the ring is the eontroller for the I the form of a lever 100 located in a position not revoluble, the controlling lever maintains substantially a constant and accessible location. Since, however, the wiping head and shell mounted revolubly within the bearing ring are frequently to be bodily inverted by a rotation effected by the handle 130, the actuating connections from the lever to the longitudinal carrier 50 must be such as to be operative in either position of the wiping head.

Referring particularly to Figs. 1, 3 and 4, the lever 100 is ,seen to extend toward the front from a pivot located at the rear upon a short bracket 101 secured directly to the bearing ring 32. The lever 100 swings horizontally to right and left about its pivot and its movements are communicated to the carrier 50 by means of a second downwardly extending connector or rod 107, which may elongate and shorten during operation and during the various adjustments. The telescopic rod 107 is provided with a downwardly hanging extension or lug 10S engaging in a slot 102 in the control lever 100, as best seen in Fig. 6. In this way the lever 100 imparts its movements to the rod 107. The latter extends downwardly from a pivot provided at its upper end connecting it to a cylindrical head 109 revolubly mounted at the extremity of a bracket 110 extending rigidly leftwise from the non-revoluble bearing ring 32. The telescopic rod is eccentrically connected to the cylindrical head 109, said head being provided with an annular groove 111, which is engaged by the retaining screw 112. This permits the head to swing to accommodate the parts to lateral adjustments of the wiper mechanisms. Also the head may be inverted if desired, and thereby the position of the pivot and the eflective length of the rod 107 altered.

The lower end of the telescopic rod 107 is connected to actuate the longitudinal carrier 50. This may be effected by means of a cylindrical plug mounted snugly but revolubly within a suitable recess in the left end of the carrier, as best seen in Fig. 6, this plug having an extension 116 to which the lower end of the rod 107 is pivoted. By this arrangement the carrier may be revolubly inverted without changing the actuating connections.

By the described arrangement, when the control lever 100 is thrown to the right, it serves to force the carrier to the right, thus advancing the wiping devices toward the shoe. It is sometimes advantageous to lock the described mechanism .in advanced position, and for this purpose the operating lever 100 may be provided with a locking lever 103, having a latch at its extremity and a spring tending to throw the latch into engagement with the teeth formed at the upper side of a fixed bracket 104 secured to the bearing ring 32. The latch engaging the teeth holds the devices in any advanced position until the depression of the latch lever the wiping action or movement relatively to the axis of the apparatus; and third, to symmetrically reverse the transverse tilt of the wiping head; thus completely, in-one shifting movement, converting the machine from one adapted to left shoes to one adapted to right shoes, and vice 'versa.

This eliminates many adjustments, manipulations, and movements as compared with prior machines such as that of said prior Patent No. 1,168,963, in which latter two separate sets of Wiping plates are employed, both requiring to be detached and replaced by others upon change of contour; and in which one set of plates has to be thrown out of position and the other set thrown into position in changing over from lefts to rights, and vice versa; and in which, upon such interchange of plates, readjustments of both the angle of action and also of the lateral tilt are required rately made.

I will now describe more in detail the devices for securing adjustment of the angle or direction of wiping action. This adjustment, as before stated, consists in transversely shifting the transverse carriage 45 more or less until an angle is secured which corresponds with the so-called swing or angularity existing between the fore and rear'parts of shoes of different styles. This setting of the angle will be performed usually by the judgment of the operator, he

"first lifting the wiping head and sliding it bodily toward the shoe to bring the wiping plates (in their retracted position) into close proximity to the inverted shoe and last.

Referring particularly to the plan View, Fig. 7 in addition to Figs, 3 and 6, it should first be remarked that, as before stated, the curved tongue-and- groove devices 43, 47 are in the form of arcs struck approximately about the center or apex F of the wiping plates for the purposes previously mentioned. The transverse carriage shifts bodily more or less about this center, carrying with it the longitudinal carrier and the wiping devices. The transverse adjustment may be effected from a hand-wheel 120 and connections mounted on the revoluble shell 34 beneath the transverse carriage. The handto be sepawheel is fixed on a short sliding shaft 121 mounted in the cross bar 41 of the shell, and the shaft is provided with a gear wheel 122 engaging a rack 123 formed at the underside of the transverse carriage and located in a recess providedfor the purpose in the parts 41, 42 of the revoluble shell.

In order to lock the carriage in the desired adjustment the following contrivance ting the machine for one shoe of a pair, is

symmetrically reversed when the wiping head is inverted to operate upon the other shoe, so that no further adjustment or judgment is required and symmetry in the shoes is better insured. I

I will now describe the means foradjusting the transverse tilt of the wiping head to suit corresponding "variations in shoes of different styles. A usual tilt is indicated by the broken line E-E,. Fig. 2, and'to secure such tilt the wiping plates herein are not adjusted relatively to the revoluble shell 34,

but, on the contrary, the capability of the shell to assume different rotary positions is made use of for the purpose. In a general way the arrangement is that in revolving the shell into position, it comes up against a suitable stop, which stops and holds and locks it in place with the desired predetermined tilt; and the extent of tilt is changed by adjustment of the stopping and locking device. In inverting the head by reverse revolution of the shell, a similar stopping and locking "action takes place; and, instead of separate adjustments, I have so provided that a single adjusting contrivance serves to symmetrically adjust the stopping and looking means in both directions, so that, when they are set for one shoe,,the inversion of the head automatically brings the parts to position withthe requisite tilt for the other shoe.

The actual revolving of the shell 34 may be accomplished by an outwardly projecting handle 130. j

The stopping devices for determining the positions comprise respectively, for the left shoe, a stop lug 131 provided on the revoluble shell and a stop dog 132. in the path thereof, and, for the right shoe, a similar stop lug 133 on the shell and stop dog 134. The stop lug and-dog for the left shoe are shown engaged. Springs 135 tend to move the dogs into their operative position shown. The stop lug and dog for the right shoe can be engaged by releasing the dog 132 and revolving the shell leftwise in Fig. 2 until the lug 133 engages the dog 134.

In additlon to Fig. 2, Fig. 4 should bereferred to, and Figs. 3 and 1.

Each stop lug consists of a separate member rigidly secured by a bolt and slot device 136 to the face of the revoluble shell. These bolt and slot devices permit relative adjustment between the lugs and shell when desired, it being understood that they would be adjusted correspondingly and there secured. The finer adjustments for variations in slightly different shoes will be separately performed, as hereinafter to be described. Each lug 131 serves to bring the shellto proper stopped position by engagement with the dogs and, in order to. lock the parts in this position, each lug is provided with a locking extension 137 having an inclined outer face to facilitate the-entry of the dog into the notch formed between the stopping face and the locking face.

Each of the dogs, which are centrally piv oted, is provided with an extension or tail 138 by which, as will be later described, the dogs may be swungfor releasing or unlocking the shell to permit revolution.

Each stop dog is mounted, preferably in a loose manner, upon a short horizontal pivot stud 139 which is supported, as seen in Fig. 4, by a small upstanding and hollow bracket 140 bolted to the bearing ring 34. The sides of this bracket are slotted at 141, as seen in Fig. 3, so as to permit the studs to shift concentrically when adjustments are performed. The stud is provided with a collar 142 engaged in the hollow interior of the bracket 140.

In order to efiect simultaneous and symmetrical adjustments of the two stop dogs 132, 134, to change the transverse tilt of the 143 being engaged by a threaded shaft 144 having reverse threads at its two ends so that when turned, by handwheel 145, the blocks a 143 and, therefore, the dogs are caused either to mutually approach or recede.

The shaft 144 is mounted in a central block 146 serving as a bearing both for rotation and for thrust. This block is mounted by a dovetail engagement 147 upon the bracket 110, before mentioned, in such way as to permit, the block to adjust itself vertically as required by the shifting movements of the dogs and threaded shaft. A

pin 148 in the bearing block 146 engages a groove in the shaft 144 to prevent endwise movement, as seen in Figs. 2 and 6. I

In order to release the dogs, a lever 150 is provided at the top of the machine, this being normally lifted by spring 51' and having downwardly extending side arms 152 arranged to bear upon and depress the tails 138 ofboth dogs when the lever is pulled down. This unlocks the shell from the dogs and permits it to be revolved as desired, the

release of the lever permitting the springs 135 to become efl'ective so that one of the responding dog upon the completion of the rotary ad ustment.

The operation of the particular mechanism above described may conveniently be substantially as follows: The left shoe A of a pair of shoes in properly pulled-over and softened condition is attached to the jack 21 in inverted position, with the toe directed toward the toe wiping mechanism. It is to be understood that the proper set or pair of wiping plates 60, 61 corresponding 2 to the style of the shoe A have been secure in place. The shoe held in the jack will then be swung about the axis D to the full line position shown in 5.

The entire toe wlplng head is lifted by the pedal 24 and is slid toward the shoe by the hand wheel 26 for the purpose of in-.

specting the relative angles, tilts, etc. While the parts are in this condition, the. operator usually by eye, but possibly with the assistance of simple accessories, makes the following adjustments or such of them as are found to be necessary. 4

He adjusts the longitudinal tilt of the wiping mechanism by means of the hand wheel 36 so that the wiping plates will stand in a plane parallel to the sole of the shoe. .For example, the head may be tilted to the extent indicated by the broken line B-B i ig. 1.

The lateral tilt may also be adjusted if necessary by means of the hand wheel 145 which shifts the positions of the stop dogs 132, 134 and in adjusting them revolubly tilts the entire wiping head and the shell .34 to the desired angle, for exam le as in;

" dicated by the broken line EE 0 Fig. 2.

- present invention may be employed without If such a jack is em loyed as that illustrated, the angle or irection of wipingaction may also require to be adjusted for; changes in style of shoe. This ad ustment any shifting or change of angle of action. For example, if a different type of jack were stop lugs will engage and lock with the cori so as to lock the reinforcin employed wherein the shoe is' pivoted to swing at the toe rather than the heel end, the

wiping action would never need to be shifted downwardly the margins so as to flatten out as much as possible all folds and wrinkles, and this result may be enhanced by the illustrated form of pedal 24 which permits the foot to be shifted so as to apply the operators Weight in pulling down instead of lifting the wiping mechanism.

At the completion of the described operation the handle 100 is manipulated to retract the wiping plates and the wiping head is then lowered to its normal position.-

Immediately the operator may remove the left shoe, shown'in full lines, and replace it by its mate, the right shoe being shown in dotted lines, in Fig. 5. This replacement may be accompanied by a slight swinging of the jack about the center D, as indicated. Accompanying this change the operator by the handle 130 revolves the shell 34. Pulling forwardly the lever 150 releases the dog stop devices and permits such revolution v to be performed, and upon releasing the lever the continued revolving motion brings the parts into the symmetrically opposite stopped position. This revolution has not only inverted the wi ing plates, thus symmetrically reversing t eir contour to suit theright shoe, but has also automatically, svmmetrica-lly reversed the lateral tilt, and if the wiping action has been performed at an incline, as seen in full lines Fig}. 5, this also is reversed symmetrically so t at the'wip ing takes place in the direction indicated by the dotted lines in Fig. 5. The locking bar 90 for the reinforcers should now be lifted blocks 80 above the wiping plates and to re ease those below the wiping plates The wiping operation as performed on the left shoe may now be repeated for the right. shoe, and the op'erators memorybeing fresh he is able to secure to best advantage symmetrical results in the two shoes.

It willthus be seen th at'I have described a lasting machine or wiping mechanism em:
