UNITED STATES PATENT OFFICE.

ERASTUS E. WINKLEY, OF LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY -CORPORATION, OF PATEBSON, NEW JERSEY, A CORPORATION F NEW JERSEY.

Application filed April 18,

This invention relates to machines for use in the manufacture ofboots and shoes for performing what is commonly termed the leveling operation, and more particularly to machines of that type in which a shoe support and a leveling tool, such as a roll, are relatively movable lengthwise of a shoe on the support to cause the tool to operate progressively along the bottom of the shoe.

lVhile such machines are used principally for shaping the outsoles of shoes, they are also sometimes used to prepare the bottom of a lasted shoe for the reception of the outsole, and the term leveling is accordingly i5 employed herein in a general sense to comprehend such different uses. The invention is herein illustrated in its application to a machine organization of the same general type as that disclosed in Letters Patent No. 1,667,7 61, granted on May 1, 1928 upon an application of E. E. lVinkley and H. A.

Davenport, and in various Letters Patent therein referred to, although it is to be understood that the invention is not thus limi ited in its applicability.

Leveling machines of the above-mentioned type have been commonly so designed as to confine the actionof the leveling roll substantially to the forepart and shank portions of the shoe bottom. Shoes, however', frequently require more or less shaping of the heel end portion of the sole, and it has been the general practice to perform this operation manually, when needed, by the use of a hammer, although it has been proposed to levelthe heel end of the shoe in the leveling machine by the use of a supplemental roll, as disclosed in a copending application of H. A. Davenport, Serial No. 147 ,007, led on November 8, 1926. In order to level satisfactorily all portions of the heel end of the sole by a leveling roll, it is necessary that the roll in its operation pass to the rear of the heel end of the shoe; and this involves the necessity of controlling the roll in such manner as to prevent it from distorting the edge of the sole in leaving the shoe or in returning to a position over the shoe. Y

The present invention, in one important aspect, accordingly provides anV improvement in means for controlling a leveling'tool or roll in leaving an end of a shoe or in returning to a position over the shoe. The in- SHOE-LEVELING MACHINE.

1928. Serial No. 271,051.

vention is illustrated as applied to an organization including a supplemental roll for operating upon the heel end of the shoe in accordance with the general disclosure of the above-mentioned Davenport application, although it is not limited to an organization o that particular character.- For the purposes in view, the construction shown comprises a roll support or receiver which is movable heightwise of the shoe to a position determined by engagement of the supplemental roll with the heel end of the shoe and is automatically locked against any substantial movement in the direction of the pressure applied by the roll from the position thus determined, the locking of the roll support being controlled by the relative movement of the shoe support and the rolls lengthwise of the shoe. Accordingly, as the roll which operates on the heel end of the 'shoe passes to the rear of the heel end,

which resultsk in the construction shown from swinging movement of the shoe Support or jack relatively to the roll, it is supported and held automatically against movement below the plane of the heel seat, so that neither in leaving the shoe nor in its return to a position over the bottom of the shoe is there any danger of damage to the edge of the sole. As herein illustrated, the roll support is carried by the jack and is so mounted and controlled that after it arrives in roll-supporting position it is stopped and held in that position while the jack continues its movement to carry the shoe past the roll. It is a further characteristic of the construction shown that the means for locking the roll support as above described acts also automatically to unlock it immediately upon the return of the roll to a position over the heel end of the shoe in the reverse movement of the jack, to permit the leveling pressure to be again applied.

In operating upon some kinds of shoes it is desirable to prevent a leveling tool or roll that operates upon the heel end of the shoe from operating upon some other portion of the shoe, in order to avoid danger of possible damage to the shoe or danger ofdistorting by the action of the heel end roll the shape produced by another roll. In operating, for example, upon shoes havinghigharched Shanks, it is desirable to prevent the heel end roll from engagingthe ball portion of the shoe which, in the leveling machine, is positioned at a height considerably above the heel-seat.Y In view of this and other considerations, the invention further provides novel means for controlling, with respect to movement heightwise of the shoe, a leveling tool or roll which operateson the heel end of the shoe, or, in another aspect, for controlling different leveling tools or rolls with respect to such movement. As herein illustrated, there is provided automatic means for controllingthe diilerent rolls independently Aof each other, so that the roll which operates at thev heel end is moved into and out of engagement with the shoe at different times from the other roll to avoid contact with portions of the shoe upon which it is not desired that it shall operate.

The above and other features of the invention, including also novel means for manually controlling the tool support with respect to movement toward or from the shoe, and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

` Fig. 1 is a View in side elevation ofa machine in which the invention is embodied;

F ig. 2 is a perspective view of a portion 'of the machine; and

Figs is a view substantially in side elevation on a larger scale of portions of the structureshown in Fig. 1, with the parts as they appear at an intermediate stage in the cycle of the machine.

Leveling machines of the type illustrated are twin machines including two sets of operating instrumentalities for operating` respectively 'on diilerent shoes in different locations in the machine. For the purpose of an understanding of this invention only onel of these sets of instrumentalities is shown in the drawings and will be hereinafter' de `'scribed since it will be understood that meehanism such as illustrated will be substantial.- ly duplicated in the opposite half of the machine, and it is further to be understood that the invention is not limited to machines of the twin type.

For supporting a shoe a tov receive the leveling pressure the machine is provided with a shoe support or jack comprising a heel post 10 and a toe post 12 which are relatively adjustable Vabout an axis at la by means of a hand wheel 16 for shoes of different sizes, the jack as a whole being movable about an axis at 18 to carry the shoe forwardly and rearwardly under'a leveling tool or roll 2O for applying leveling pressure to the forepart and shank portions of the shoe bottom. The leveling roll 20 is mounted on a holder 22y which is supported on a roll carrier 24 pivoted at 26 on the frame of Vdisclosed in Letters Patent the machine for swinging movements in a vertical plane to pressthe roll upon the shoe and to withdraw it from Vthe shoe at different times in the cycle of operations. To cause the roll to operate progressively along the bottom of the shoe the 'jack is swung about its axis 18 by power-operated mechanism, which it is unnecessary to describe in detail lsince it is fully described in prior Letters Patent including those hereinbefore referred to. The cycle of operations, which inay be variously modilied as far as the present invention is concerned, may comprise as heretofore first a full forward movement of the jack to cause the roll 2Ol to traverse the shoe bottom from the toe end to the rear end of the shank, then a plurality of short backward and forward vmovements while the roll is operating` at one side of the shank, thereafter long backward and forward movements to cause the roll to return to the toe end along one side and then to operate from the toe to the rear of the shank along the opposite side, followed by a plurality of short backward and forward movements while the roll is operating `at that side of the shank and'iinally a movement to cause the roll to return to the toe. In thecourse of these operations the roll may be tipped in various ways by movement of its holder 22, as also fully disclosed in the prior Letters lbatent.V

' At the beginning of the operation of the machine the roll 20 is supported in a position somewhat above the level of the toe end of the shoe, as illustrated in Fig. 1, by yieldlable means including a spring plunger 27, as fully disclosed in the Tvllinkley and Davenport patent hereinbefore mentioned. For moving the roll down into engagement f'ith the toe end of the shoe bottom lat the beginning of the cycle ofoperations and for releasing it to permit it to be raised by the plunger V27 at the end of the cycle, there is provided a cam wheel 28 on a cam shaft 30, the periphery of this cam wheel being' arranged to act on a lever 32 connected by a link 34 to a lever 36 on the frame of the machine. The lever 86 is arranged to bear upon the upper end of a plunger 38 which acts through a spring 40 on a lever 42 connccted by a link `44C to the roll carrier 2st. Through these connectionsv the roll 2O is made to bear yieldingly upon the bottom of the shoe. As illustrated, the cam wheel 28 is so formed as to adapt it to relieve the pressure of the roll 20 on the shoe at certain times between the beginning and the end of the cycle; but there is preferably alsov provided means for rendering it ineffective thus to Vrelieve the pressure in operating on shoes that do not require such pressure relief, as No. 1,685,387, granted on September 25, 1928 upon an application of E. E. llfinkley and l?. V. Hart.

fl U

The machine herein shown is further provided with an additional levellingr tool or roll 46 for applying leveling pressure to the heel end of the shoe bottom while the roll 2() is operating upon other portions, especially the shank. This roll is mounted for turning movement in a holder 48 having an upwardly extendingr shank 50 mount-ed in a roll carrier bracket 52 which is secured to another bracket 54 pivoted at 56 on a roll carrier arm or lever 58 pivotally mounted at 60 on the frame of the machine. Y The holder 48 can be turned about the axis of its shank 50 to position the roll 46 at different angles laterally ot the shoe, and it is secured in adjusted position by means of a lscrew 62 whereby the shank 50 is clamped in the bracket 52. rIhe bracket 52 is secured to the bracket 54 by clamping screws 64 which extend through slots in the bracket 52, as shown in Fig. 2, to permit the roll to be adjustably tipped about an axis extending lengthwise ot' the shoe. By movement ot' the bracket 54 about the axis of its pivot 56 the roll 46 mayl be positioned at different distances lengthwise ot the shoe from the roll 20, and the bracket 54 is secured in adjusted position by means of a clamping screw 66 on the arm 58. The means thus far described tor supporting and adjusting the roll 46 is similar tol what is disclosed in the Davenport application v hereinbefore mentioned.Y f

For one of the purposes ot the present invention the machine is provided with novel means for controlling the roll 46 with respect to movement heightwise ofthe shoe into or out of enga-gement with the shoe. It is desirable that this roll be positioned close enough to the roll 20 so that it may operate upon the heel end of the shoe while the roll 20 is operating on the shank portion of the shoe. lVith the two rolls in that relation to each other there are times in the cvcle of the machine when the roll 46 is located over the orepart ot' the shoe, as illustrated for example in F ig. l. It is usually preferable, however, that the roll 46 be confined in its operation substantially to the heel end ot' the shoe, in order to avoid objectionable results such as might arise from its engagement with other portions of the shoe. .Automatic means is accordingly provided for controlling the roll-carrying arm 58 inde pendently of the carrier 24 for the roll 20, so that in the forward movement ot the jack the roll 46 is not moved downwardly into engagement with the shoe until that time in the cycle when it is positioned substantially or approximately over the heel end of the shoe, and so that in the reverse movement of the jack it is lifted out of engagement with the shoe before the parts are in position for it to act to any substantial extent on portions of the shoe .bottom in front of vroll receiver 1702.

the heel seat. For this purpose the cam shaft- 30 carries a path cam 68 whichengages a roll on one end of avlever 7() pivoted at 72 on the frame of the machine, the other end of this lever being connected to a Vrod 74 which is slidingly movable through a bushing 7 6 threaded in one end of a sleeve member 7 8 which is pivotally mounted at 80 on the arm 58. l Between the bushing 76 and a flange 82 on the rod 74 there is mounted a spring 84 through which pressure is applied yieldingly to the arm 58 by the lever to force the roll 46 downwardly against the shoe. The rod 74- carries at its outer end nuts 86 for engaging the bushing 7 6 to afl'ord a positive connection between the lever 70 and the arm 58 to lift the roll 46 from the shoe. The path cam 68 is so formed as to force the roll 46 downwardly upon the shoe when the jack has been moved far enough forwardly to bring the shoe substantially into position for this roll to act on its heel end portion, and to lift the roll from the shoe at the corresponding time in the reverse movement of the jack, the roll thusbeing lowered and lifted in each full reciprocation of the jack in the cycle of the machine.

In order that the roll 46 shall apply its pressure evenly to all portions of the heel end of the shoe bottom, it is desirable that in each forward movement of the jack the 1 heel end of the shoe shallbe carried beyond this roll. In order, however, to avoid danger of damage to the rear .edge of the sole, it is necessary to prevent the roll in that movement of the jack from dropping oil' the heel end of the shoeand also to control it in such manner as to prevent it from delivering a blow on the rear edge of the sole in its ret-urn to a position over the shoe bottom in the reverse movement ofthe jack. The invention accordingly further provides novel means for accomplishing this result. For the purpose in view there `is pivotally mounted at 88 on the heel-supporting portion 10 of the jack an arm 90 which carries a roll-supporting device on its upper end. The arm 90 is provided with a lug 92 engaged by a spring plunger 94 tending to swing the arm forwardly toward the heel end of the shoe and for limiting the swinging movement in this direction the arm carries a rubber -pad 96 arranged to engage the heell end face of the shoe. Slidably mounted in a bore in the arm 90 is a rod or plunger 98 fast on the upper `end of which is a bracket 100 having mounted thereon a U-shaped roll supporting member or The two arms of this member are arranged to extend forwardly at opposite sides of the heel end of the shoe and are provided withyinclined faces 104 arranged vto be engaged by diametrically reduced portions `106 at the opposite'ends of the roll 16, and also with hollows or de -ber rand its supporting bracket downwardly against the resista-nce of the spring as the jack-is moved forwardly to cause the roll to operate along the heel scat, the reduced portions of the roll entering the depressions 108 before the shoe is moved :tar enough to carry'it beyond the roll. The member 102 is provided with a'spindle 112 mounted in the bracket 100 for turnii'ig movement about an axis extending lengthwise of the shoe, so that the member 102 can tip laterally to adjust itself to the direction of the axis of the roll 416. For limiting such tipping movement theV spindle 112 is provided with a projection 114A which etc tends into a slot formed in the bracket 100, as shown in Fig. 2. To prevent turning movement of the roll support about the axis of the plunger 98 the bracket 100 has a pair of downwardly extending arms 116, only one of which is seen in the drawings, these arms being arranged to engage lugs 118 projecting laterally from the upper end of the arm 90. To limit adjustably upward movement of the roll supportV in response to the action of the spring110, one of the arms 116 carries a screw 120 for engaging the lug 118 at that side oi the arm 90. f

It will thus be seen that as the roll 16 operates on the heel end portion of the shoe bottom the roll support, comprising the

members

100 and 102, is adjusted automatically by the action of the roll to height determined by engagement ofthe roll with the heel end ot' the shoe bottom. To rein lder the yroll support effective to prevent any substantial. downward movement of the roll below the plane of the heel seat when the roll ispositioned at the rear of the heel end of the shoe, there is further provided means for locking the support against any substantial downward movement from the position to which it is adjusted in the manner "above described. F or this purpose the arm 90 is provided with a series of upwardly directed ratchet teeth 122 and the downwardly extending arms 116 of the bracket 100 carry apair of pawls or latches 1211 pivotally mounted on a rod 126 which eX- tends acrossA from one arm to the other. The ends of these pawls are spaced apart vertically -a distance less than the distance between adjacent ratchet teeth for the purpose of greater precision. Each pawl is provided with a tail portion 128, and associated therewith is a pawl controller comvprisinga curved arm 130 also pivoted on the rod 126 and having on its lower end laterally extending lugs which carry rods 132 (F ig. 8) projecting upwardly through openings in the tails 128 of the pawls, these rods hai/'ing thereon springs 134 through which the pawls are swung inwardly against the` ratchet teeth in response to swinging movement or' the arm 130 toward the lett (Fig. Such movement of the armV 180 is effected automatically ata time in the cycle before the roll reaches the rear edge of the heel end of the shoe bottom by the action of a portion of the roll-carrying bracket member 5.2 upon a screw 136 adjustably mounted in a holder 138 secured to the upper end of the arm 130. Prior to that time in the cycle the pawls 1211 are held out of engagement with the ratchet teeth by the action ot the arm 130 upon their tail portions 128 under the influence ot a spring 139 the opposite ends of which are connected respectively to the arm 180 and to the member 100. A shoulder 140 on the arm 180 is arranged to engage the member 100 to limit its movement under the force of the spring 139, as shown in Fig-3.1 and 2. V

t is vdesirable that before a shoe is mounted on the jack the means for supporting the roll at the heel end shall be swung away from the shoe-supporting portion of the jack, that is, to the left -from the position that it occupies iirFig. 1, so as not to interfere with the presentation ot the shoe. For this purpose there is conveniently utilized mechanism such as provided heretofore for use in jacking the slice, features of which are described and claimed in a. ccpending application of E. E. inkley and H. A. Davenport, Serial No. 12,287, led on February 28, 1925. This mechanism comprises a pivoted'hand lever 1/12 having arms that extend at opposite sides of the heel post 10, as shown in Fig. 2, and con- Vnected by'means fully described in the Aabove-menti.onedV application to a bar 141- which acts on a swinging heel-pin carrier 14.6 to tip the shoe in a direction to force its. toe end down uponv a toe rest 1118. It will be understood that such jacking of the shoe is effected by downward movement oic the hand lever, and that prior to the jacking operation the lever occupies position higher than that in which it is shown in the drawings. l'n order to utilize this lever to control the roll support, the arm 90 is provided with a projection having portions at the opposite sides ci the arm on which are formed inclined lower Faces 152, and the two side arms oi the lever 142 are provided with rolls 154 in position to engage these inclined faces ant thereby to force the arm 90 rearwardly against the re sistance of the spring plunger 9e. lNhen the shoe is jacked by downward movement of'tlielever, the arm 90 is released and is swung toward the shoe by the plunger 94 until the pad 96 engages the end face of the shoe.

In the operation of the machine, a shoe is first mounted on the jack and the lever 142 isthen moved downwardly by the operator to jack the shoe firmly on the toe rest 148 and to release the arm 90 and permit it to be swung toward the heel end of the shoe in the manner above described. The jack is then vswung forward manually to the position indicated in Fig. 1, as usual in machines of the type illustrated. Upon the starting of the machine the jack is swung forwardly by its cam and the forepart and shank-leveling roll 20 is moved downwardly to engage the shoe in the well-known manner characteristic of machines of this type. Downward movement of the heel end leveling roll 46, however, is delayed until the heel end portion of the shoe arrives substantially in position to receive the pressure of the roll. The roll 46 is then forced downwardly by the action of its cam 68, and is held in its lowered position under the influence of the spring 84 until such time as in the reverse swinging movement of the jack the roll 20 is caused to return to the toe end of the shoe, whereupon the roll 46 is lifted by its cam to prevent it from engaging the shoe for any substantial distance forwardly of the heel seat. It will be understood that in a cycle of operations such as hereinbefore described the roll 46 is thus. lifted twice in the cycle in time relation to the return of the roll 20 to the toe and is depressed twice in time relation to the progress of the roll 20 from the toe end rearwardly. If the cycle includes, as hereinbefore described, a plurality of short reciprocations of the jack to cause the roll 20 tov operate repeatedly along each side of the shank, the roll 46 simultaneously operates repeatedly along the heel seat. Each time that the roll 46 operates rearwardly along the heel scat, its reduced end portions 106 engage the inclined faces 104 of the rollsupporting member 102 and depress this member and itflsupporting bracket 100 to a osition determined by engagement of the roll with the heel seat face of the shoe, the reduced portions of the roll entering the depressions 108 just before the shoe is in position to pass from under the roll. Each time that the shoe is moved forwardly far enough to carry' its heel end beyond the roll 46, the pawls 124 are moved into engagement with the ratchet teeth 122 by the action of the roll-carrying bracket 52 on the arm 180, so that the roll support is locked against any substantial downward movement from the position determined by the roll in engagement with the heel 'seat` The roll is thus supported at such a height as to prevent it from drop Ding downwardly at the rear end of the shoe in such manner as to bend theedge of the sole and in position for the shoe' to. be moved under it again ywithout damage to the sole. Itl will be un- 'supporting parts against the resistance of the spring plunger 94 while the shoe is moved forward to cause the roll 20 to operate along the 'rear end` portion of the shank. In the reverse swinging movement of the jack'the shoe is returned toward the roll support until its rear end face engages the pad 96, and then the roll support 'is carried rearwardly with the shoe simultaneously with the withdrawal of the pawls 124 from eng-agement with the ratchet teeth, so that the roll 46 is again permitted to apply its pressure to the heel end portion of the sole. Y

The invention is herein illustrated with reference to the application of leveling pressure to a slice of the stitchdown type, but it is to be understood that it is not limited to use in operating on shoes of that particular type but is generally applicable to machines for leveling various kinds of shoes.
