UPFER-SHAPING MACE-ENE.

Application filed .Tune' 15,

This invention relates to machinesrfor use in the manufacture of boots and shoes for shaping the upper materials; andis herein illustrated in its application toa well-known type of bed lasting machine; and more particularly as applied to means for shaping the toe portion of the upper materials Itswi'll be'recognized, however, thatin many of its aspects the invention is not limited to a machine of the type shown nor restricted in its applicability to the shaping of the toeend portion of the upper.

In machines which include in their organization means for effecting relative movement between the upper shaping or lasting mechanism and the shoe heightwise of the shoe, for example to accomplish what is usually termed the upwiping ofthe up'peryit is important to terminate such relative move ment at the point Where the wipers and the shoe are in proper relation for the overwiping operation, in order that the upper may be wiped inwardly over the bottom of the shoe in the most et't'ective manner and also in order that the wipers may not lose effective control of the upper between the upwiping and overwiping operations, as they are likely to do if the upwiping operation is carried too far. In the well-known commercail type of bed lasting machine the operator presses the wipers inwardly about the toe by the use of the usual hand lever while he opcrates the treadle to move the wipers heightwiseof the toe, and in determining when to stop the upwiping operation he is governed principally by the decrease of resistance encountered when the wipers pass above the edge of the shoe bottom. In the use of such an organization the tendency is to raise the wipers too far with consequentdanger'of losing to some extent the control of the up-' per, and the best results in lasting require the exercise of considerable care in order to avoid such consequences. V

The present invention, in one important aspect, provides a novelconstruction and arrangement of means for limiting; the abovedescribed relative movement between upper shaping or lasting means and the shoe in the direction of the height "of the shoe; In the construction shown the limit of upwiping movement of the wipers is determined for each shoe by relative adjustmentof parts of the wiper-operating mechanism under control of a device which is positionedby en- 1922.

1 gagementwith the bottom of the shoe." More limit of movement. and the effective length of which is determined by the action of the shoeengaging means. Insurance is thus af-' forded that for each particular shoe the upwipinp; operation-will be terminated at the proper point and the wipers willbe positioned in the most effective relation to the shoe for the overwiping operation without any lossof control of the upper materials.

A further feature of the invention'consists in novel; means for varying the limit of relati ve movement of lasting means and the shoe in proportion to relative adjustment between such means and the shoe. The machine hereinshown. as usual inmachines of the type illustrated, includes means for adjusting the wipers relatively to the shoe by tilting them about an axis iextending laterally of the shoe and for purposes of the invention a connection is provided between the wiper adjusting means and the means for deter- ,n'iining'bv engagement with the bottom of the shoe the limit of upwiping movement of the wipers. as a further means of control to compensate for adjustment of the wipers.

Another feature of the invention consists in novel means for effecting in succession a relative movement of the shoe and the lasting means or wipers for upwiping the upper and a relative movement in the reverse direction for com-pressing the margin'of the upper on the bottom of the shoe. These opupper limit of movement determined as hereinbefore described and which is thereafter broken by further movement of the treadle in the same direction to move the wipers downwardly to compress the margin of the upper. A novel feature of the invention also consists in means for signaling theoperator at-the point. where the relative movement of no I the lasting means and the shoe is reversed to indicate that the overwiping operation should be performed, such means in the construction herein shown comprising a device which becomes operative to oppose yielding resistance to continued movement of the treadle at that point in its movement when the toggle is in straightened condition.

Still another feature consists in novel means for preventingundue drag of the wipers on the upper materials as they are retracted from over the shoe, the illustrative embodiment of this feature comprisng adevice which acts automatically on the reverse movement of the treadle to lengthen the toggle by which downward compressing movement is imparted to the wipers, thereby raising the wipers during their return movement to a position higher than that which they occupy at the beginning of their compressing movement.

In a further important aspect, a novel feature of the invention consists in the provision of means for facilitating correct relative adjustment between a shoe and means for operating on the shoe, this feature of the invention being illustrated herein in its relation to angular adjustment of the end-embracing wipers to position them in substantially parallel relation to the plane of that portion of the shoe bot-tom upon which they are to operate. Machines of the type illustrated include adjusting devices which are utilized to tip the wipers lengthwise and laterally of the shoe, and heretofore such adjustments have been made without any definite assurance as to when the wipers are properly positioned for the most effective action on the shoe.

For purposes of this invention the machine herein shown has mechanism which is associated with and controlled by the wiperadjusting means for indicating visually to the operator the angular position of the wipers. While the proper position which the wipers should assume for the most effective results may be determined in different ways, the machine herein shown is further provided, as an important feature, with means for measuring the inclination of the shoe bottom. More particularly, the constructions shown comprises a hold-down having members for engaging the bottom of the shoe at different locations and mechanism operated by relative movement of said mem bers to indicate to the operator the inclination of the shoe bottom both lengthwise and laterally of the shoe. By observing the measured inclination of the shoe bottom, and by correspondingly adjusting the wipers as determined by their indicating mechanism, the operator is thus enabled quickly and accurately to set the wipers in accordance with the requirements of the shoe.

Still another important feature of the invention consists in novel wiper operating and controlling means having particularly in view the correct conformity of the wipers to the shoe and effective pressure of the wipers on all parts of the shoe which they engage. For the purposes in view, the construction shown comprises a novel organization including compensating mechanism whereby the wipers adjust themselves to the toe with relative pressures automatically proportioned as between the end and the sides of the toe, and also as between the opposite sides of the toe, in response to the resistance which they encounter, and which may be substantially equalized at all points U about the end of the shoe. This construction is particularly useful in a machine of the type herein shown wherein the wipers are utilized to wipe the upper heightwise of the shoe, since they adjust themselves to the different contours of the shoe at different levels while maintaining an effective wiping pressure at the sides of the toe as well as at the end of the toe. For the purpose of preventing premature closing of the wipers. the construction shown also includes means for preventing such closing movement until the wipers have been advanced substantially to the end of the toe, including also provision for shifting movement of the wipers toward the right or the left upon their engagement with the shoe. Since it is desirable on some kinds of work that in the overwiping operation the wipers receive advancing and closing movements in fixed proportion to each other, the invention further provides means for preventing compensating action of the wipers as they are advanced and closedin the ovcrwiping of the upper. To facilitate these different operations of the wipers mechanism is provided for locking or releasing different parts of the operating connections as required at different times in the operative movements of the wipers. For operating and controlling the wipers in the manner described, the construction shown comprises various relatively movable parts, including a system of relatively movable racks and pinions. and features of the invention are also to be recognized in different combinations and relations of these parts.

The above and other features of the invention, including also various combinations and details not hereinabove particularly set forth, will now be described with reference to the accompanying drawings and pointed out in the claims.

The illustrated machine comprises generally a suitable frame 20, a heel support 22, a toe support 24, devices indicated at 26 for lasting the heel end of a shoe,'and devices to be further described for operating on the toe end of the shoe. Power maybe delivered to the machine for jacking the shoe by means of a belt engaging pulley 28 (Fig. 10), which operates through a cyclic clutch to turn a crank 30 (Fig. 1), which in turn operates the main cam shaft through pawland-ratchet connections as described in United States Letters Patent No. 1,37 3,482, granted April 5 1921, on application of Matthias Brock. i

The toe-lasting devices are carried by a head 40, arranged to be tilted about spindle 42 by manipulation of handle 44, the spindle 42 being mounted in bearings in an upper slide 45 which is mounted to be shiftshowing the lower part.

ed angularly with respect to a laterallymovable slide {IE6 by the use of hand wheel 50, slide 46 being arranged to be moved automatically widthwise of the shoe during the up-wiping movement of the lasting head, as shown in United Stat-es Letters Patent N0."1,390,755, granted Sept. 13, 1921, on applicationoir' Matthias Brock. Slide 48, which supports slide 46, is longitudinally movable under the control of handwheel e19 on a vertically movable slide 52 arranged to be raised and lowered by a link 54. Tlhese various parts may be, and are illustrated as being, similar to the corresponding parts shown in the above-identified Letters Patent.

As has been explained, the raising and lowering of slide 52 is arranged to be con trolled by means, illustrated as comprising a holddown 6O engaging the shoe, which acts as a feeler controlled by the shoe to vary the effective action of a treadle in such a manner that the wiper members are raised to a predetermined height with respect to the height of the shoe bottom, whereupon further movement or treadle 62, in the same direction after or during the inward movement of the wipers, moves slide 52 in the opposite direction to apply heavy pressure to the wiped-over upper materials of the shoe.

The hold-down is mounted on a sliding rod 64, and is lowered in the customary manner by a link 66 connected to treadle (58. A bracket 70 is securely clamped on rod (5 and on this bracket. is formed a supporting face which is formed with an undercut groove slidingly to receive a rack block 74. The bottom projecting portion oibracket 7 0 has a threaded hole for a threaded adjusting bolt 7 2 passing through and secured against longitudinal movement in block 74sliding in the groove formed in the rack bracket, to raise and lower the block on the 7 bracket. A sector 76, meshing with rack 74, is secured to, a rock-shaft 77 (Fig. 10) having a lever arm 78 (Fig. 1) adjustably secured by passing a pin through one or several holes to a link 80 connected to the link 5a which operates slide 52. The rocking of sector 76 by downward movement ot the hold-down thus serves to move a roll carried by the bifurcated end of link 5 k in a slot 82 in a lever 84:, which is fulcrumed at 86 on a bracket attached to the machine frame and is connected to treadle 62 by means of a

toggle

88, 90. By this arrangement movement of link 5% by link 80 varies the effective length 01 lever arm 8% so that completely straightening

wipers exactly up to the desired predeter mined posit-ion, here shown as being the position required for wiping inwardly over the shoe bottom. Further movement of treadle 62 in'the-salne direction, during or we I after the over-wiping operation, shortens the toggle and brings the wipers down on the wiped-over materials with a hoary ironing pressure.

in order to coordinate the position of the wipers with that of hold-down 60, the iatter adjustable on its supporting rod 6%, bcing loosely mounted between flanges 2st, 96 formed on a sleeve which is threaded on rod 6} and about which the hold-down may swing to and from position over a shoe in the machine. The sleeve is arranged to be turned by a handle 92 that is fast on the flange 96 to adjustthe hold-down verticall to coordinate its position with that of the wipers. he hold-down is held in adjusted vertical position by a suitable spring ratchet device 98, one part of which is carried by rod 64 and the other by flange ea, and wh'ch is arranged to permit turning in either direction, while preventing the setting from being accidentally disturbed, and which locks the sleeve to rod 641.

F or the double purpose of serving as a counter-balance for the wiper-head in compressing the upper materials of a shoe against a last, and as a stop to assist the operator in determining when to move the Wipers inwardly, a sliding rod 100 is yielc ingly urged toward the left in Fig, 1 by a spring 102 engaging a collar on the rod, far as permitted by locknuts on the end of the rod (not shown), which en age the frame through which the rod slides. This rod is so constructed and arranged that just as

toggle

88, 90 is straightened, raising the wiper-head to its highest position, its head 10a is engaged by a set screw 106 in an arm 108 clamped on a rock-shaft 110 which carries treadle 62 (Figs. 1 and 10). In order to insure the breaking of toggle 88., 90 on the reverse movement, the knuckle of the engaged by a spring pressed plunger a.

By this arrangement, on the upward movement of the wiper head, while the wipers are held in engagement with the upper materials of the shoe in the usual manner, plunger 112 is pushed to the right, until enga ment of set-screw 106 with head 10a notifies the operator to move the wipers in- 'dly over the shoe bottom. While treadle 62 may be held stationary during this mo tion of the wipers, this is not essential, as the vertical motion of head 52 is comparatively slow while the toggle is justapproaching and receding from its straightened po sition, a considerable arc of movement of member 00 at this time having comparatively small vertical component. During further manipulation of treadle 62, spring 102 is compressed and acts to counter-balance the weight of the wiper-head during its downward motion in compressing the upper materials upon the shoe bottom. When i'naterials by undue friction from the wipers as they are retracted. For this purpose, the secondary toggle shown in for member 90 shown in secondary toggle ismade up of L l, 116 which are pivoted together "is nber 11 1 is in two parts, the terminating in an abutment face 6 anged toengage either of two 4 ul y related faces 120, 122 on thebottom of member 116.

116 and 68 during the first. part of the return movement, and whenit is released the secondary toggle 114i, 116 acts as aunit to form a primary toggle with member 88. This compound toggle arrangement automatically provides for retracting the wipers at a higher level, and prevents any possible drag on the work.

It will be observed that aciustmcnt of the wiper-headby handle-4 1, rocking it about spindle 42, changes the vertical position of the wipers and therefore disturbs the coor' dination of the wipers and hold-down 60. [in important feature of my invention provides for convenient compensation for this adjustment, preferably by means controlled by the adjustment itself. As illustrated, the spindle controlled by handle 1- is connected by means of a universal oint to a telescoping drive shaft 182, which is connected by a second universal joint to the threaded adjusting bolt 72. Thus manipulation of handie as to adjust the head about spindle 42 iii) automatically raises or lowers rack block 74 to compensate ion-the movement of the:

' The novel wiper-operating and compensating mechanism shown in Figsi'l, 7, 8, 1-2 and 13, is controlled, as stated above, by hand, lever 144-, which is pivoted at 180. on

Pinions Q22] and {238*iare secured on spindles" which extend upwardly through

slots

248 and 250 in cover plate 218, and which carry segmental ratchet arms 252 and 25 1 (Fi 8).

Slides

220 and 232 respectively carry spaced

lugs

256 and 258, be-

1 tween which are pivoted locking pawls 260 .and 262 (Figs. 1, 8, and 13), normally spring-pressed upwardly, but which can be depressed against ratchet

arms

252 and 254 to lock pinions 222 and 23o respectively to slides 220 and

Lugs

256 and 258, with their pawls, move in slots 26 1 and 266 in cover plate 218 as shown in Fi 13 and in dotted lines in Fig. 8.

The locking and unlocking of the various parts is controlled by rock shaft 216 which is manipulated by sliding handle 186 back and forth. Shaft 216 carries an arm 268, in the end of which is a spring-pressed plunger 269 13) to engage and depress pawl 260, and there is also mounted on the shaft a sleeve 270 formed with a lug (Figs. 8 and 12) to operate plunger 286 ant an arm 274- which has an intermediate portion to engage theend of pawl 2&6, and which is formed with a head 275 carrying a springpressed plunger 273 to operate pawl 262.

Rocking the shaft 216 in one direction, by pulling handle 186 toward the operator to its first position, thus operates plunger 286 to release slide 230, allows pawl 2et6 to lock slide 226 to plate 150, and leaves

pawls

260 and 262 in upper or idle position, thus releasing

pinions

222 and 288. in this position movement of hand lever letsforward moves the whole wiper mechanism carried by plate 150 forward, for example to carry the wipers against the end face of the shoe, the wipers being free to turn tpgether'to the right or the left in fixed relation to each other, to adjust themselves to the position of the toe by diiferenial movement of slides 289, but being locked against closing by pawl 246.

Moving handle 186 to rock shaft 216 to its intermediate or second position releases plunger 236, allowing pawl 284i to lock slide 280 to the head 40 through ratchet 2 18, and trips pawl 2 l6 to release slide 226, but does not operate pawls 26D and 262, so that

pinions

222 and 288 may turn. New movement of hand lever 14% operates slide 226, pinion 222 rolls on rack 22% to advance rack 226, pinion 228 rolls on the stationary rack 280 to advance rack 282 at twice the speed of rack 226, and therefore racks 289 turn pinions 24:0 and 2&2 to close the wipers. As pinion 288 is at this time free, it acts as a compensating connection between the wipers, and as the pinion is moved bodily forward to close the wipersit will turn if the resistance encountered by either of the wipers is greater than that encountered by the other, and thus substantially equalize the pressures of the wipers against the shoe at the opposite sides of the toe. Moreover,

since the pinion 2221s free to turn and acts as a compensating connection between the wiper carrier and the closing slide 226,-it serves at the same time to proportion the forward pressure of the wipers automaticaL ly to their closing pressure, and it may be substantially to equalize these pressures. 'ihat is, pinion 222 pushes on rack 224: to advance plate 150 (.and with it the wipers) and at. the same time the pinion 222 may roll on rack 22st and pinion 228 on rack 280 to close the wipers. This results in a selfadjustment of the wipers to the shoe, however the contour of the shoe may vary, and is especially advantageous in the upwipe, since successive horizontal sections of a last and shoe at different levels may diil'er materially in outline. As the operator holds the wipers closed about the toe in the upwiping operation, they are thus at all times in the most effective position relatively to the last and shoe, throughout this operation. This insures adequate wiping pressure at the sides of the toe aswell as at the end of the toe.

Rocking shaft 216 by moving handle 186 toward the machine to its third position leaves rack 230 locked to the head, or stationary with respect to the relatively movable plate 150, and also leaves rack 226 free from pawl 2 16, but additionally operates to lock pinions 222 and 238 by depressing

pawls

260 and 262. Pinion 238 being thus locked, there is no differential or compensating relative movement of the Wipers, which, however, are closed over the shoe bottom as slide 232advances over plate 150. Looking the pinion 222 prevents movement of slide 226 relatively to plate 150, and thus eliminates the opportunity for self-adjustment or com-' pensation as between the advance and the closing of the wipers. Pinion 228 rolls on the relativelystationary rack 230, however, and thus advances rack 232 to close the wipers. This insures a definite relation between the closing and forward movements of the wipers in a manner which retains, for the over-wiping operation, the advantages of the manner of operation of machines of the type shown in the above-identified Letters Patent. 7

To secure the utmost benefit from the in proved wiper operation, the wipersshould be adjusted to the inclination of the shoe bottom with great exactness. To facilitate such adjustment, handle 14i is arranged to operate an indicator, shown as a graduated drum 282 (Fig. 8), and handle 162 operates a similar indicator comprising a graduated drum 28a. Each drum is in the form of a gear loosely mounted on the spindle operated by its as sociated handle and is driven therefrom by suitable reduction gearing 286 (Fig. 11).

In the illustrated embodiment of my inspaced points, and includes mechanism operated by such engagement to measure and indicate the transverse and longitudinal inclinations of the shoe bottom. The operation of this indicating mechanism is shown in Figs. .345 inclusive, and is effected by three shoe engaging plungers, one of which, indicated at 288, engages near the point of the toe, the others, 290 and 292, engaging at opposite sides approximately in the vertical plane of the tip seam (Fig. 1).

As shown in Fig. 5,

plungers

290 and 292 are pivoted on an equalizer bar 294, and

slide through sleeves 296, which can be adjusted by a right-andleft-threaded screw 298 for shoes of different widths. Bar 294: is pivoted on a vertically movable slide 300, forn'ied with a rack on one side of its upper end (Fig. 3), and carries a segmental rack 302 meshing with a pinion 304i fastened on the same spindle 306 as a second segmental rack 308, which meshes with a pinion 310 carried by th indicator drum 812. Pinion 810 and drum 312 are loosely mounted on the spindle which connects bar 294 to slide 300, and so move vertically with the slide. The transverse inclination of'the shoe bottom measured by this mechanism is read through an opening 314 in the casing of the hold-down. A suitable pointer may be provided if desired.

The longitudinalinclination of the shoe bottomis determined by measuring the dif ferential movement-of plunger 288 and slide 300 (which may be regarded as controlled by a median point between 'plungers 290 and 292). The rack teeth on slide 300 engage a pinion 316, which meshes with teeth on plunger 288, permitting such a differential movement. As shown in Fig. 6, this movement is measured bythe action of a pinion 818 meshing witha second set of rack teeth on one side of plunger 288, this movement being transmitted through a large pinion 320 to a second small pinion 322 carried by measuring drum 324:. The longitudinal inclination of the shoe is read on this drum through an opening 326.

By this arrangement, when the hold-down is brought against the bottom of a shoe in the machine, dials or drums 312 and 32st indicate exactly the transverse and longitudinal inclinations. By operating

handles

44 and 162 to obtain corresponding readings on

indicators

282 and 284, accuracy of adjustment of the wipers to the shoe is insured.

As all four of the indicators include means to multiply the motion which is measured, the readings are practically micrometer readings, making possible an accuracy which could not be attained even by a skilled operator by eye measurements alone, and this accuracy is readily attainable by a relatively unskilled operator.

In operation, a last and shoe are acked in the machine in the usual way, the heel being lasted as with the present commercial mabottom, hand lever 144: is manipulatedto bring them up to the shoe. During this preliminary advance of the wipers, they have no closing movement, but are free to turn together to the right or left to adjust then'iselves to the position of the'toe.

During the wiping of the upper materials upwardly against the sides of the last by manipulation of treadle 62, the wipers are held by the operator closed about the toe of the shoe by means of hand lever 144, and sliding handle 186 is at this time held in its middle position, in order to allow the wipers a compound compensating or differential motion, to equalize the pressure tending to move each wiper against'the shoe and the pressure urging them bodily forward against the toe of the shoe, thereby securing uniforinity of pressure as between the sides and end of the toe. Thus the wipers remain throughout the upwiping operation in effective engagement with the upper materials all around the toe, regardless of variations in the contour of the last at different levels. The upper limit of this upward movement is automatically set by the hold-down, acting through rack block 74.

Immediately following the upwiping operation, the upper materials are gathered and wiped inwardly over the shoe bottom by further manipulation of hand lever 144, the wipers being locked against all differential or self-adjusting motion by shifting sliding handle 186 to its extreme position away from the operator on hand lever 144. This arrai'igement retains a great advantage of the present commercial machine, in that the advancing and closing movements bear a predetermined definite relation to one another. There is, however, this additional advantage that the wipers have previously automatically and exactly adjusted themselves to the contour of the shoe bottom during their upward wiping movement, and are thus set for the most eITective action during their inward wiping movement. During the inward moven'ient of the wipers, the upper materials are compacted against the shoe bottom by further depression of treadle 62, this operation being facilitated by reasonof the fact that it is not necessary to reverse the operation of the treadle, High quality work is rendered more certain by the impossibility of raising the wipers above the shoe bottom far enough to loosen the upper materials atthe end of the upwiping operation, and

'3 during the first part of the closing movement of the wipers, before they are pressed heavily toward the shoe bottom.

After the upper materials are secured in place, by tacking or wiring, as the case may be, the' various parts are returned to their initial. positions by releasing treadle 62, returning hand lever 1dr, and unjacking the shoe by operating the usual knee lever (not shown).
