y2S Claims.

.This invention relates to lasting machines, and is herein illustrated as. embodied in Va machine for lasting with adhesive. .It is to be understood, however, `that Vfeatures of the invention vare not limited to lasting with adhesive or to use in a machine .ci the exact construction herein disclosed.

vIt fis an object of Vthis invention .to provide a novel and improved lasting .machine which is of relatively .simple :and inexpensive construction, yet eiiicient .and `dependable .in operation. With this end in View, and in accordance with -a feature of the invention, .the herein illustrated machine is provided withnovel and improved means for tensioni-ng the stock rto be :lasted comprising amember having an endless friction surface Ifor engaging one .side of the 'lasting .margin of the stock, and .movable in ya direction extending heightwise `of -a shoe presented to the machine, a second member for engaging ,the .opposite side ofsaid lastingimargin, andmeansfor periodically effecting relative approaching movement of these members .to .cause the .friction surface vto exert a .-frictional .drag on the .lasting .margin thereby to tension .the stock .heightwise Tof the shoe.

.More particularly, the first-mentioned member consists oi an endless .exible element, e. g., a belt, having ia :friction .surface for engaging the outer .side .of vthe l-lasting vmargin of the stock,

while the `second mentioned member comprises n a lasting shield, associated with a .shoe-bottom rest, having .an operating surface `for engaging the inner side .of the .lasting margin and movable, with `the endless member, during the tensioning action. movements of these members, an idler pulley is arranged .to vbear .against the endless `member and means are provided vfor V.causing this idler tpulley .periodically to move .the endless eX-ible `member toward the :lasting shield and into fric- 4tional engagement with thelasting .marginof .the stock.

In order to 'facilitate the lasting operation, and in accordance with a further feature of the Vinvention, the `above-mentioned -novel tensioning means arearrangedaiso .to .effect aieeding of the shoe. Preferably, andas herein illustrated, this is .accomplished by Yproviding means for moving .the endless flexible element, lasting shield and shoe-bottom rest, together and transversely of the direction in which .the stock is being tensiOned. At the completion of these tensioning and feeding actions, the Vidler pulley is operated to `permit the endless iiexible element to move away (from the lasting shield and these members,

.For effecting the relative approaching d together with .the shoe-bottom rest, 'are moved reversely, i. e., back fed, to 'their original positions. This cycle of operations is repeated's'o that the stools is tensione'd in different locations, su'ccessively, along the edge of the bottom of 'the shoe.

During the aforementioned back-'feeding'movement of .the .endless flexible element, lasting shield and shoe-bottom rest, the shoe is held against retrograde movement by'pressin'g means arranged to lay the lasting margin ci the .tensioned stock `down on and to press it against, the bottom of the shoe. This pressing means is operated .in 'time relation 4to the 'tensioning and feedingaction, mentioned above, and, "in accordance with a'further feature of the invention, is adapted to move toward the bottom of the 'shoe with a component of Amovement inwardly 'from the 'edge .of the shoe bottom. Preferably, and as herein illustrated, the pressing means comprises a hammer that'is pivotally mounted on the end of a lever which is itself pivoted to an oscil lated operating arm. The hammer is `yieldingly held in a position such that an Operating lface thereon is inclined to the 'bottom of .theshoe and the lever, on which the ,hammer is mounted, is yieldable relatively to the operating arm. 'The arrangement is such that, as the operating .arm is oscillated, the .hammer firstengages thelasting l-margin of the .stock at the very edge of .the shoe bottom,.then pivots `on the end of the lever and swings down to `bear iiatly against the lasting vmargin -on the shoe bottom, and nallyapplies pressure to the lastingmargin withia definite component of movement inwardly from the edge Lof the shoe bottom, as the lever yieldingly pivots on the operating arm. This combined .pressing and irl-wiping action of the hammerassures tig-htness of the stock by avoiding any tendency of the pressing action alone to iloosenitaround the edge oi :the shoe bottom.

vThe above Yand `other 'features of the inven tion, including various novel details .of construc- 'tion and combinations of parts, will lnow be more particularly described kwith reference vto the accompanying drawings and `thereafter Vpointed 1out in the claims.

In the drawings,

Fig. .2"is a View in side elevation 'of the machine shown in Fig. l .and 'with a portion of the machine .fr'ame broken away to show the operating mechanism; i

Fig. 3 is a view in side elevation, with certain parts in section, of a portion of the operating mechanism in a position assumed during the operation of the machine;

Fig. 4 is a view in front elevation of the operating mechanism in the position shown in Fig. 3; and

Figs. 5 and 6 are views in side elevation, with certain parts in section, of other portions of the operating mechanisms in two different positions assumed during the operation of the machine.

Referring now to the drawings, the operative elements of the machine include a constantly running belt I0 for tensioning the stock to be lasted, also operable to impart a feeding movement to the shoe, a hammer I2 for laying the lasting margin of the tensioned stock down on, and for pressing it against, the bottom of a shoe, a lasting shiel-d, or abutment, I4, for supporting the lasting margin of the stock as it is engaged by the belt, and an idler pulley I6 for moving the belt periodically into engagement with the stock. During the operation of the machine, the shoe being lasted is supported by the operator and held against upward movement, in response to the tensioning action of the belt, by means of a bottom rest I8 associated with the aforementioned lasting shield I4. The belt I0, idler pulley I6, lasting shield I4 and the shoe-bottom rest are all movable as a unit laterally of the machine to effect a feeding movement of the shoe. The hammer I2, which presses the lasting margin of the tensioned stock against the shoe bottom, is operated in time relation to the action of the tensioning and feeding instrumentalties, just mentioned, and operates to hold the shoe against retrograde movement, while these instrumentalities are moved reversely, or back fed, to their original positions. During this back-feeding movement, the idler pulley is shifted rearwardly of the machine to permit the belt to move away from the stock.

The operating elements are supported on, and operated by mechanism contained within a head construction comprising a pair of vertically extending side plates 20, 22, secured at their lower ends, by bolts 24, 24 to a base member 28. This base member is mounted on the upper end of a column 30 of a suitable height to b-ring the operating elements of the machine to the proper level for the operator. A treadle 32 is arranged to be supported on the iioor by means of a bracket 34 and from this treadle a treadle rod 36 extends upwardly through a bore 30 formed in the base member 28, A compression spring 40, interposed between the upper surface of the base member 28 and a collar 42 on the treadle rod, ginds to hold the rod in the position shown in The belt I0, which may be formed of rubber, fabric or other suitable material, is of the wellknown V-type so as to present a flat friction surface II and is mounted on a lower drive pulley 50 and an upper pulley 52, see Figs. 1 and 2. The drive pulley 50 is secured to a shaft 54 which is journaled in bearings 56 and 58, carried by the plates 20 and 22 respectively. This shaft extends beyond the plate 22 and is provided with a power input pulley 60 which is driven, from a motor, or other source of power (not shown), by means of a belt 62. The upper pulley 52 is formed integrally with two face cams 64, 66 and a side cam 68 and this whole assemblage is rotatably mounted on a bushing 10, carried by a shaft 'l2 that is adjustably secured to the upper ends of the plates 20 and 22 by means of clamp nuts 14, 14, see Fig. 1.

The idler pulley I6 is supported on an arm 80 which extends downwardly from a bracket 82 that is rotatably mounted on a shaft 84 by means of three spaced and apertured ears 86, 08 and 80, see Fig. 4. Also rotatably mounted on the shaft 84, and positioned between the ears 86 and 88 of the bracket 82, is an upwardly extending arm 92 which carries a cam roll 94 adapted to engage the cam 64, Figs. 2 and 3. The ears 86 andV 88 of the bracket 82 extend rearwardly and support a boss 96 having a bore 98 in which is positioned a plunger |00. This plunger is yield- `ingly urged against the arm 92 by means of a compression spring |02 the strength of which may be varied by means of a threaded plug |04. When the cam 64 is in the position shown in Fig. 2, the idler pulley I6 bears lightly against the inside face of the belt |0 and the spring |02 is substantially relaxed. However, when the cam 64 assumes the position shown in Fig. 3, the idler pulley I6 will be projected outwardli7 to move the belt. toward the lasting shield I4, yieldingly through the action of spring |02, and to the position shown. The lower end of the arm 92 is formed with a surface |06 against which a stop screw |08, in the bracket 82, bears when the parts are in the positions shown in Fig- 2. By adjusting the screw |08 the initial position of the pulley I 6 with respect to the belt, Fig. 2, may be Varied.

The shaft 84 is journaled at one end in a bushing IIO, threaded into the plate 20 and held in place by means of a lock nut I|2, Fig. 4. On the other end of this shaft, a sleeve I I4, having an enlarged portion providing a shoulder IIS, is secured, and this sleeve is journaled in a bore I|8 in theplate 22. Also rotatably mounted on the shaft 84, between the ear 90 of the bracket 82 and the sleeve I I4, is a lever |20, to the outer end of whichthe shoe-bottom rest I8 is adjustably secured by means of a screw |22, and an arm |24, which is positioned adjacent to the ear 88, of the bracket 82, and is separated from the ear of thisv bracket by a bushing |26. A compression spring |28, interposed between the bushing IIO and the ear 86, on the bracket 82- tends to hold the shaft 84, together with the bracket 82 and arms |20 and |24, to the right, Fig. 1, with the shoulder IIS on the sleeve ||4 against the plate 22. During the operation of the machine, however, these parts are shifted to the left, toward the hammer I 2 and to the position shown in Fig. 4, periodically, by means of the cam 68 which acts through a lever |30'. This lever is pivotally mounted on the plate 22 by means of a block |32 and trunnion shaft |34 and has at one end a cam roll |36 for engaging the cam 68. A screw |38 is threaded through the other end of the lever |30 and is arranged to engage the end of the shaft 84. A lock nut I 40 is provided for holding the screw I 38 in adjusted position.

On the inner end of the lever |20 there is a stud |50 which is embraced by a bifurcated end |52 on a lever |54, Figs. 2 and 3. This lever is pivoted to the plate 22 by means of a stud I 56 and is connected to the treadle rod 36. When the treadle 32 is released and the rod 36 elevated by the spring 40, the lever |54 is swung in a clockwise direction to the extent determined by a stop pin |58 on the plate 22. This movement of the lever |54 swings the lever I 20, in a counterclockwise direction and to the position shown in Fig. 2, and moves the shoe-bottom rest I8v and lasting shield I4 outwardly and -upw-ardlyaway from the belt I8: When the parts are in this position, the outward movement of the belt; I8

bymeansof the cam 64 and idlerpulley I6 is notsuf'cient tQbring ,the friction surface II of the belt into contact with the lasting shield I4. However, when the treadle is depressed, the `shoebottom rest |8 and lasting shield I4 will be swung downwardly and Aimvardly toward the belt-and will assume the positions shown in 3 in which the swinging movement of the lever |54 has been arrested by an eccentric Vstop |59 which is mounted on the plate 22.` Now, when the belt I0 Vis moved outwardly by the pulley i6 its friotion surface |v willcontact the lasting shield le, or the lasting margin of stock interposed between the shield I4 and the belt, e. g., the lasting marV gin of the cover C of a platform shoe comprising an upper U and platform? assembled on alast L. Theshoe-bottom rest i8 which-bears against the platform P prevents upward movementof the shoe in response to the frictional drag now imposed on the lasting margin of the cover C by the friction surface II of the beltrlii, which is moving in the direction indicated by the arrow in Fig. 3. The lasting shield I4, which is pivotally mounted onV the end of the arm |24 and guided on the shoe-bottom rest by means of a pin |66 and a slot |62, is, however, free to move upwardly. Thus, each time the belt I8 is moved outwardly by the pulley I6, operated by the cam 64, it presses the lasting margin of the cover against the shield I4 and then tensions it in a vertical direction, the lasting shield moving upwardly with the stock during this tensioning action, see Fig. 3. Whenthe belt In is withdrawn, as the cam 64 assumes the Yposition shown in Fig. 2, the frictional drag on the stool; ceases and the lasting shield is returned to the position shown in Fig. 2 by the action of a springpressed plunger |64, associated with the arm |24`and bearing against a surface |66 on the bracket 82, see Figs.l 5 and 6;

While the idler pulley I6 is in the position shown in Fig. 3 and the belt Il) still exerting a frictional drag on the .lasting margin of the cover C, the cam 63 operates the lever |39v to shift the shaft 84, bracket 82, together with the idler pulley i8 and the arms |26rand |24, which carry the shoe.bottom restv I8 and the lasting shield lli, respectively, to the left and tothe positions shown in Fig. e, and thefshoe is moved along a corresponding distance. At, the compleN tion of this feeding movement of the shoe, the belt Il! moves away from the lasting shield and out of engagement with the lasting marginof the cover, cam 64 having now rotated from the position shownin Fig. 3 toward that shown in Fig.V 2. The idler pulley i6, together with the belt I0, the lasting shield ifi and the shoe-bottom rest I8 are next moved reversely, i. e., back fed, by the action of the spring |28 that is now permitted by the cam 88 which has rotated away vfrom the position shown in Fig. 4, Thus these parts are returned, i. e., back fed, to the position shown in Fig. 1. This cycle of tensioning and feeding actions is repeatedso that successive portions of the lasting margin-of the cover C are brought into engagement with, and tensioned by,the fries. tion surface I I on the constantly running belt is,

At the completion of each feeding-action and just before the frictional engagementvof the belt I0 with the lasting margin is terminated, by the rearward movement of the belt as above explained, that portion of Athelasting margin of the-tensioned-stock-justrbeyond the belt, i. e.,

6; to the left, Fig 4,- is -laid down on and .pressed firmlyzagainst the shoe bottom, i. e., platform P, bythe hammer I2. The lasting margin of the cover and/or -the bottom face of the platformv having been Apreviously treated with adhesive, this action of the hammer-|2 will cause the cover to be secured tothe platform. Thus, as the operation proceeds, successiveportions of the lasting margin `of the cover are first tensioned by the belt and then-laid down on and secured in lasted position to the platform.

The hammer .|2-'ispivotally mounted on the outer end of a lever |18, by means of a pin |12 in the arm and an arcuate slot IM formed in a rib E16 on the hammer, Figs. 2, 5 and 6. A -coil spring |18, connected at one end to the arm |18 and at the otherv end to the hammer, tends to hold the hammer yieldingly in the inclined position shown in Figs. 2 and 5. The lever |18 is pivotally mounted, by means of a stud |86, on an arm |82 which is itself pivotally mounted on a cross shaft |84 that is supported by the plates 2G, 22.` Also-pivotally mounted Von the stud I 85| is a lugl.. The lever |18 has an end |88 which bears against a plunger |98 that is mounted in a thimble |92, threaded into the arm |82. A compression spring |94, in back of the plunger |98,.tends toswingvthe -lever in a clockwise di rection about the axis of the stud I 88 to the extent permitted .by the head of Va stop screw |96, threaded intorthe arm I 82. A coil spring |98, stretched between the upper end of the arm |82 and a crossbar 200, carried by the plates 26, 2.2, holds the arm |82, yieldingly, in the position shown inl Fig.v 2 and with the head of the stud |88 against a-stop pin 202 that extends inwardly from the plate 28.

The hammer is operated by oscillating the arm 82 about the axis of the shaft |84 and this action is effected by the cam 66 in the following manner. A lever 2li), having a cam roll 2l2 mounted `on its upper end, is pivotally supported on the plate 20 by means `of a stud 2M. At the lower end of this lever there is an operating nose 2|6 whichis adapted to engage the end of the lug |86 ywhen thislug is swung upwardly to the positionshown in Figs 5 and 6. A coil spring ZIB, connectedto the nose 2'I6 and to 'the crossbar 288, tends `to hold the cam roll '2I2 against the cam 66 andthe `lever 2li) in the vposition shown in Fig.A 2; For swinging the lug |85 up wardlyto bring its end into 'alinement with the nose 2|6- on the lever 2|9, a lever 22E) having a spring finger 222,` engaging the lug, is provided. This lever is pivotally mounted on a crossbar 22d, carried-'by the plates 20 and 212, and is provided with'a bifurcated-end arranged to embrace the treadle rod 38. A collar 225 is secured to treadle rod 36v in a `position toswing the lever 228m a counterclockwise direction, and to the position shown in Figs. *5'and 6, when the treadle 3211s depressed, thus elevating the lug |86 so that Aits end is in front ofthe nose 2|6. When the treadle 32 isreleased, however, a coil spring 228, connected to the lever 228 and also to the crossbar 208, returnsthe lever l22|) to the position shown inFig. 2,- detennined by a stop 238, and permits the lugalSS-.to swing downwardly away from the noseY 2|8, thus terminatingthe action of the hammer I2.

The action of thehammer I2 may best be understoodby-reference to Figs. 2, 5 and 6 of the drawings. In Fig.` 2, the treadle 32 is released and the lever 2|() now merely oscillates without the -nose2|6. engaging the lug |86 and the ham- .aaaaiacY mer I2 is, accordingly, idle. In Fig.' 5 the hammer I2 is shown in a position assumed `at the beginning of its action and when the arm |82 has been swung inwardly by the cam 66 and lever 2li), the treadle now being ydepressed to elevate lug |86. The hammer is now engaging the lasting margin of the cover C and is holding it against the edge of the platform P. The end |88 of the lever |18, however, is still being held against the stop screw I 95 by the plunger |90 and the spring |94 and the hammer I2 is held in the inclined position shown by the Spring |18. Now, as the arm |82 is swung still further toward the shoe, by the cam 66 and the lever 2|0, the hammer I2 is moved to the position shown in Fig. 6 in which it lays the lasting margin of the cover C down on and presses it against the bottom face of the platform P. As the hammer moves from the position shown in Fig. 5 to that shown in Fig. 6, it first pivots on the end of lever il() so as to lie flatly on the bottom of the shoe. Then, as arm |82 continues to swing outwardly, the lever IIS turns on the stud |80, against the resistance of spring IM. As the `arm I 82 thus turns, the hammer moves inwardly from the edge of the shoe while still applying yielding pressure to the lasting margin of the cover C. Thus the hammer has an appreciable component of movement inwardly from the edge of the bottom of the platform P so that, in addition to laying the lasting margin down and pressing it against the platform, the hammer also has a denite inwiping action. This in-wiping action is very important since it tends to draw the lasting margin inwardly from the edge of the bottom of the platform and thus augments the tensioning action of the belt I8. Also, in the absence of such wiping action, the pressing action of the hammer alone might tend to loosen the cover C around the edge of the platform P.

In operating the machine, the shoe is presented thereto, by the operator, bottom up and with the lasting margin of the stock to be lasted, e. g., the cover C, inside of the lasting shield I2, with the treadle released and the operating elements of the machine in the positions shown in Fig. 2. As the treadle is depressed, the operator holds the bottom of the shoe upwardly against the shoe-bottom rest I8 land then permits the shoe to move inwardly, toward the belt Iii,

with the shoe-bottom rest and lasting shield. Immediately, the tensioning and feeding actions begin as the idle pulley I6 moves the belt I8 outwardly to cause its friction surface to exert a frictional drag on the stock and the cam 68 operates to shift the belt I0, lasting shield I4 and shoe-bottom rest I8 in a direction to feed the shoe. Depression of the treadle also initiates the action of the hammer I2 which lays the lasting margin of the cover C down on, and presses it against, the bottom of the shoe, i. e., the platform P, with an in-wiping action as described above. The operator merely supports and guides the shoe as the lasting operation proceeds. When the lasting operation, which may be continued around the entire periphery of the shoe bottom, or along only a portion thereof, has been completed the treadle is released and the shoe is removed from the machine.

While the herein illustrated machine is particularly adapted for, and has been described as, performing the so-called cover-lasting operation, it will be understood that it is not limited to such use. On the contrary, it is designed for, and capable of, performing a lasting operation on conventional shoes wherein the lasting margin of the stock, i. e., the upper, is secured to a shoe-bottom member, i. e., an insole,'with adhesive.
