BELASTING MACHINE;

Application filed February 7, 1921. Serial No. 443,043.

This inventionrelates to shoe making, and is illustrated as embodied in apparatus for mounting shoes onlasts. This operat on is of special importance in connection w th since it is the relasting that is primarily rel-asting or second lasting turn shoes, relied upon to give shoes of that sort their final form. In various aspects, however, the invention is not limited to such use.

According to present'practice shoes are usually relasted by hand, and in tur n shoe manufacture especially the operation is very laborious. During therelasting operation, if the heel or shank portion of the shoe-is held stationary while'the last is forced into the shoe, or it the last is hold while the shoe is pulled thereon by means engaging the counter or shank portions or the rear of the sole, the strain longitudinally of the shoe causes a marked narrowing of the forepart of the shoe. As every efiort to force the last into the shoe increases thismarrowing action, while the proper seating of the last in the shoe involves a broadening of the forepart of the shoe due to the forwardly tapering form of the forward portion of the last, such pulling may produce a relasted shoe which seems very tight on the last so long as tension is maintained but which is found to be loose when the tension. is re leased. f

On the other hand, if the shoe is pushed rather than pulled on the last, as occurs in using means engaging the shoe forwardly of the shank, the forward portion of the shoe is broadened as it is pushed on the last, thus permitting easier insertion of the last, and tightening instead of loosening the shoe on the last when the pressure. on it is released. The marked difference between pushing and pulling on the shoe may readily be demonstrated by first pulling manually on the counter portion of a shoe,

. and then pushing on the forward portion.

In thus pushing shoes on lasts, it is desira ble to vary the power applied to the shoes, as lasts of different shapes. and shoes of dif ferent materials and under different conditions require different amounts of power.

plication promptly when the last is properly seated in the shoe, so as to avoid unduly straining the toe of the shoe by pushing it against the end of the last.

One object of the present invention is to provide an improved relasting machine the operation of which will overcome the difficulties and avoid the undesirable results above adverted to in connection with relasting operations as they are usually performed.

To the attainment of the above-stated object an important feature of the invention consists in the provision, in a relasting machine, of shoe-pushing means engaging the forward portion of a shoe and comprising an impositively-engaging part, that is to say a friction surface or a suction member, which will slip when the toe of the last seats in the tip of the shoe, thussuddenly increasing'the resistance to the movement of the shoe. In

this Way the advantages of pushing a shoe on a last are secured, while the friction or suction may be so gaged that the surface will slip as soon as the toe of the last engages thetip of its shoe, thereby avoiding undue strain on the shoe. In the preferred embodiment of the invention] illustrated herein, the pushing means is a rotatable shoe-engaging roll, on the surface of which there may be, if desired, suction or vacuum gripping cups.- i

A still further object of the invention is to improve the seating of the counter portions of shoes on last-s, and inthis aspect the invention consists in the provision of novel mechanism for operating a shoe horn ina close imitationof the best manual manipulation of such a horn in relasting the counter portionot' the shoe. Further to improve the seating of the counter portion of the shoe, and to co-operate with the means, illustrated as a horn, for drawing thispart of the shoe over the last, there is provided means progressively to force theshoe bottom against the last. As illustrated, the shoe-engaging roll which seats the toe portion of the shoe may be moved rearwardly of, and in yielding engagement with, the shoe bottom, to co-operate with the shoe horn in relasting the counter portion of the shoe. e d

Other features of. the invention consist in the provision of an improved last support arranged automatically to withdraw the lasted shoe from the shoe-seatingdevices, and a novel mounting for the roll such that it may be used to cause relative twisting of the last and shoe.

. These and other objects of the invention will be apparent from the following de scription of the invention in connection with an illustrative machine shown in the, append ed drawings, in which Figs. 1 to 7 are diagrammatic views illustrating my improved method of mounting a shoe on a last and showing the various positions of the roll and horn of the machine;

The improved machine shown in illustrative embodiment in these drawing-s comprises a friction roll E, which, as hereinafter explained, may be provided with a suction S'riphing surface in the form of vacuun'i cups, as shown in Fig. 15, and a shoe horn H, which devices are moved by suitable mechanism hereinafter described to assume various relative positions as shown in Figs.

the toe of the last, pushing the shoe rear wardly on the last to the position shown in Fig. 2. Thereafter the roll, freely rotating on its bearingso that it enages the bottom or the shoe with a rolling friction only, is moved rearwardly as shown'in Figs. 3', 4 and 5 while constantly maintained in engagement with the sole by the heavy spring pressure. At the same time the horn H is rocked about the point of the heel of the last to draw the sition'while the last pin 150 is turned up- -wardly to hold he lastedshoe in a convenient position for removal as shown in Fig. 7. This sequence of operations will be discussed in'niore detail after describing the operating mechanism of the illustrative machine shown in the accompanying drawings.

The machine-is enclosed in a suitable casing 20 and is driven by an electric motor 22 which drives worm 24 through a belt 26. Wei-11124 meshes with and drlvcs a constantly rotating worm gear 28 to which is secured a, gear 30 which meshes with and drives a constantly rotating gear 32. I

Upon depression of atreadle 34 a rod 36 is moved downwardlyagainst the tension of as 3rin '38 shown in Fi 9 to rock a lever 1g. 11) to pull upwardly on a wedge 42 which throws a suitable clutch 44 against This the tension of its enclosed spring. causes shaft 46 'tofirotate as long as the trea-dle 34is held down. 'Fixedly mounted on shaft 46 is apinion 100 which rotates therewith, and as shown in Figs. 8 and 9 this pinion meshes with a gear 102 to rotate a pinion on a shaft 104 which, through suit able sprockets and a chain 106, rotatesthe rollR '1 M WVhen the treadle 34 is oscillated to the right in Fig. 10 about pivot48 it rocks the bell crank lever 50 to the right in Fig. 12 compressing a spring 52 and moving a pawl 54 upwardly. This pawl foroes a rod 56 upwardly against the tension of aspring 58 until the pawl rides off the point'GO, whereupon the spring. 58 forces 'rod 56 downwardly again until the abutment 62' seats on the pawl. Upon releasing the treadle, the spring 52 swings it to the left in Fig. 12, causing the aawl 54 to be rocked downwardly to snap over the point carried by rod .56. As

shown in Fig. 11-, when the rod 56 is moved upwardly y the operation ofthetreadle it trips aHorton clutch 64 which is provided with several abutmentsbti. This clutch secures together the constantly rotating gear 28 and'the shaft 68 during that part of a rotation which serves to bring succeeding abutments 66 in contact w'th the pawl'l'O actuated bythe rod'56, as-is usual in the opera that a complete rotation of shaft 68 is designed to operate the various mechanisms of the machine through one complete cycle, and that the various stops may be positioned so that the machine will stop after each succeeding operation has been fully performer on the shoe, 'whereupon the operator may again'move treadle 8 1 to trip the clutch for the performance of the next succeeding operation. More or fewer of these abutments 66 may be provided, as desired, fewer stops being needed by the more skillful operatives. Loosely mounted on shaft 46 for rotation relatively thereto is a series of operating devices, and fixedly mounted on shaft 68 is i a corresponding series of cams to actuate them in proper sequence. This part of the actuating mechanism is shown in detail in Fig. 13, and partly in dotted lines in Fig. 9.

The frame 108 which carries the roll R is loosely mounted on the shaft l l'which is carried by a bell crank lever 110. One end of this bell crank lever is supported by a heavy spring 112 surrounding a rod 11 1 supported by the casing of the machine. The

spring 112 is supported by an adjusting nut 116 in order to permit adjustment of the force which it exerts. This spring 112 is in tended to force-the roll R upwardly int-o constant, adjustable, yielding engagement with the sole of the shoe being operated upon as shown in 9, when the bell crank lever 110 is released.

The lower end. of the bell crank lever 110 bearsa cam roll 11.8 which is arranged to ride on a earn 120 carried by the shaft 68. When this cam 120 engages the cam roll 118 it forces the cam roll upwardly, thereby pull.- ing the bearing 101 and the roll it downwardly while compressing the spring 112. The cam 120 is so constructed and arranged that at the starting position it engages the roll 118 and therefore maintains the friction roll it in a lowered position. The first tripping of the Horton clutch rotates the shaft 68 only far enough to release thecam roll 118 from engagement with cam 120, as shown in Fig. 9, and stops before actuating any of the other mechanisms. The roll R is at this time in the position shown in Fig. 9 and in this position it may be rotated by depressing the treadle 3 1-. By the engagement of the roll ll with the sole of the shoe the roll pushes the shoe rearwardly to seat'the toe portion on the last. Fig. 2 shows the completion of this operation.

During the seating of the counter portion of the shoe-on the last, the shoeengaging roll 1 is intended to be moved rearwardly to bring the bottom of the shoe progressively against the last under pressure derived from the spring 112, thereby aiding the shoe horn in drawing'the counter portion of the shoe over the last. The spring 112 may have a tension of from 200 to 500 pounds, 300 pounds being a suitable tension for ordinary turn shoes, and is designed to lose not more than or pounds of this tension during the upward movement to engage the roll with the bottom of the shoe. A link" 122 is secured to the roll-carrying frame 108 on a bearing 124; and is also secured to a bell crank lever 126 loosely mounted on the shaft 40. The opposite end of the bell crank lever 12 bears a cam roll which contacts with a cam 128 fixedly mounted on the shaft 68 to rock the bell crank lever'126 to oscillate the frame 108 to the right in Fig. 9. As it is desired to be able to adjust the extent to which the shoe-engagingroll It moves to the left in Fig. 9, the extreme end 130 (Fig. 13) of the lever 126 is designed to contact with an adjustable abutment 132 as shown in dotted lines in Fig. 9. The adjustable abutment 132 is threaded through a portion 12s of the casing of the machine and can be rotated by gear 136 actuated by a rotatable handle 138 (Fig. 10). By adjusting the abutment 132 further to the left in Fig. 9 the initial position of the friction rollR is moved to the right in the same figure. The,

abutment engages the end 130 of the bell crank lever 126 and lifts the-roll carried by I this lever from engagement with the cam 128, which would otherwise permit it to rock further. Bell crank lever 126 is biased counter-clockwise (as viewed in Fig. 9) by a spring 300 secured to the frame of the machine, tomaintain engagement with cam 128 or with abutment 182, asthe case may be.

In seating. certain kinds of shoes, particularly those'which are to be mounted on very narrow and crooked lasts, it is desirable to move one side of the shoe rearwardly of the last more rapidly than the other side, thereby twisting the shoe relative to the'last. As shown in Fig. 10 this is accomplished by the use of a concave roll R which may be moved axially by a hand lever 1-10 while the roll R is rotating, to seat the toe portion of a shoe on the last. While the angular movement of vall parts of the roll R is the same it will be evident that the linear movement of an article engaging the higher partof the roll will be greater than that of an article engaging the lower part. In general, the l 5t forced. against that side of the shoe which has the slower rearward movement; that is, the last is crowded relatively in the direction in which the handle 1 10 is moved. The best line in a shoe is secured when the last is crowded toward the inner side of the shoe, and therefore the handle will usually be moved in the direction of the inner side. This brings a thicker portion of the roll B. into engagement with the outer side of the shoe, moving the outer side rearwardly faster than the inner side. The twisting so produced orowcs the lastfimnlyagainst the inner side of the shoe, securing a fineness of line heretofore obtainable only by manipulation of the shoe with a shoe hammer subsequent to the relastiiigoperation.

One form of construction of the roll is shown in Fig. 15. According to this construction the surface of the roll is formed with vacuum cups 142 which, when pressed against the sole, adhere thereto by suction. The roll is formed with a wear resisting surface 144, such as rubber and canvas, containing the vacuum cups 142, beneath which is a highly resilient layer 146 which is illustrated as being made of sponge rubber, but which might readily be made in the. form of a pneumatic or other cushion.

A last pin 150 is mounted in a support 152 7 support from the position shown in Fig. 9 to the-position shown in Fig. 7. The abutment 160 is mounted for manual releasing of the latch, which may at times be desirable quickly to withdraw the last from the shoe-seating devices, to avoid injury or marring of the shoe. The abutment 162 is arranged to be engaged by an abutment carried by the reciprocating shoe horn support as hereinafter explained. The last pin support is carried by a curved neck 164 which is high enough so that the upper of a. high shoe may be received therein. tects the shoe horn and its reciprocatng support, which move inside thereof.

The shoe horn H is pivotally mounted in a reciprocating support 200 which is carried by an oscillating bell crank lever 202 14) mounted on a bearing 204. The bell crank lever 202 is made up of two arms, the arm-206 carrying the reciprocating support 200 and the arm 208 carrying a cam roll arranged to engage the cam 210 (Fig. 13) to oscillate the bell crank lever about the pivotal bearing 204. The two

arms

206 and 208 are connected by a rod 212 carried by the arm 208 and the rod 212 carries an adjustable abutment 214 bearing against a spring 216 which engages a projection on the arm 20.6. This provides for yielding oscillation of the arm 206. A second adjustable abutment 215 makes possible a variation inthe initial relative position of the

arms

206 and 208, by crowding the arm 206 upwardly against the spring 216. Mounted on the bearing 204, in engagement with a rack surface 218 on the shoe. horn support 200, is a gear 220 (Fig. 9). This gear 220 is rotated This curved neck also pro-.

also carries an abutment 232 constructed and arranged to engage the abutment 162 ofthe latch for the last pin to release the last pin at the end of the cycle of the machine. Bell crank lever 224 is biased counter-clockwise by a spring 301 to maintain engagement with cam 226. a

A preferred construction of the shoe horn is shown in detail in Fig. 16, and is also indioated in Fig. 8. In this form a second member 234is mounted on the bearing 228 to form with the horn H a jaw. to grip the counter portion of the shoe. This member 234 is urged'into engagement with the shoe horn H by a spring 236 andsaid'member is in the form of a bell crank lever of which one end 238, on the downward movement of the shoe horn at the end of thecycle, will engage an adjustable stop 240 which causes the opening of the jaw for the insertion of the next .shoe. The jaw automatically closes during the very first part of the upward movement of the shoe horn support. It will be observed that the tension of spring 236 may be adjusted by means shown at 242 to avoid sufficient pressure to injure any of the various kinds of shoes. g

It will be observed that by the illustrative preferred construction of the machine, the shoe is held in such a way that there are no obstructions to interfere with the operative in guiding it and in operating on it in the usual way with a shoe hammer. This is much facilitated by holdingthe'shoe right side up, as shown.

In operation, at the beginning of the cycle of the machine the last pin 150 is in the position shown in Fig. 7 A last partially inserted in a shoe is seated on the last pin and swungdownwardly and rearwardly into the substantially horizontal position shown in Fig. l. The initial position of thehorn H is such that during this movement of the last the horn will normally find its way be: tween the last and the shoe as shown in Figs. 1 and 9, and will maintain the last in engagement with the last pin until the roll R is raised into engagement with the sole of the shoe. The operative now arranges the shoe in suitable co -operative relation to the shoe-engaging roll R, and the I trcadle 34 is swung tothe right in Fig. 10 'toutrip the Horton clutch. This rotates the shaft 68- just far enough so'that cam 120 is rotated out of engagement with the cam roll 118 and bell crank lever is thereby released, whereupon the spring 112 moves the shoe-engaging roll R and its frame 108 upwardly, the oam'roll 118 following the retreating surface of thecam to prevent any sudden or jarring release of the roll, until the roll engages the sole of the shoe, as shown in Fig. 9, under the'heavy adjustable spring pressure provided bythe spring 1152. At this time the first stop 66 on the Horton clutch comes into action and the clutch is thrown out to stop the rotation of shaft 68.

The operator now depresses the treadle 3 1 to throw the clutch 44L, causing the shoe-engaging roll to rotate and push the shoe rearwardly on the last. As previously plained, during this rearward movement of the shoe he may move the shoe-engagingroll It axially by operation of thehandle M0 to cause one side of the shoe to be moved rear wardly more rapidly than the other side thus allowing for .seatingshocs on very nar row and crooked lasts. l/loreover, during this, operation, he may manipulate the shoe relatively to the last by the use ofa shoe hammer, exercising his skill and judgment in co-operation with the force exerted by the machine, to improve the seating and appearance of the shoe.

It would naturally be thought that the seating of the shoe on the last during this operation would be facilitated by urging the upper rearwardly at the same time as the sole. It is found, however, that in reality the reverse is the case and that the seating of the shoe is actually facilitated by retarding the rearward movement of the upper. This may be because the nnportant feature of this operation is to seat the relatively unyielding sole in proper relation to the bottom of the last, and this is more easily done if the upper is not at this time stretched into its final position on the last. The upper is thereafter readily drawn into place partly by its own elasticity and partly during the pulling of the heel up into place on the last. in the case of some kinds of shoes which are diliicult to seat properly, this part of the operation may be facilitated by glancing or wedging blows struck with a shoe hammer against the toe portion of the upper of the shoe duringthe rearward movement of the sole to urge the upper relatively forward with respect to the sole.

The toe portion of the shoe having been properly seated-in this way the treadleBt is released, stopping the rotation of the shoe engaging roll under power, and leaving the roll free to turn in contact with the sole of the shoe during thebodily rearward movement of theroll. It is to be noted, however, that the roll may againjbe rotated, if desired, at any time in the subsequent operations, by depressing the treadle 3% The Horton clutch is again tripped whereupon the frame 108 is oscillated by the bell crank lever 126 to move the friction roll rearwardly into the successive positions shown in Figs. '3, 4 and 5. Shortly after this movement of the roll is inaugurated the bell crank lever 224 isoscillated to reciprocats the shoe horn support 200 while at the sametime the bell crank lever 202 is oscillated,.yieldingly to move the shoe horn forwardly. The resultant of these two motions is a movement of the bearing 228 in the path shown in a dotted line in Fig. 9, first rocking the shoe horn H about the heel of the last as a fulcrum against the tension of spring 230 into the position shown Fig.

and then drawing it upwardly as, shown the last, while simultaneously leveling the sole against, and conforming it to the shape of, the last. The shoe horn is moved up wardly far enough to withdraw it from the shoe and the reciprocation of the support 200 stops just before the abutment 232 thereonengages the abutment 162 to release the latch holding the last pin. During the latter part of this movement of the shoe horn the roll R moves forwardly into the shank of the shoe as shown in Fig. 6 whereupon the Hortonclutch is thrown out and the machine comes to rest. I

As the shoe is now holdunder heavy pressure of from 200 to 500 pounds, which shapes the shank firmly into engagement with the last, this a very good time to secure the upper portions of the shoe about the last. This operation is usually performed by inserting the block B and lacing, as illustrated in Fig. 6, but it may be done in some kinds of shoes by buttoning and in pumps by tacking aprotruding portion of the lining to the last. If preferred, fasteners may be used such as are disclosed in Letters Patent of the. Unit-ed States No. 1,496,020, granted June 3, 192%, upon application of Charles F. Pym. The expression securing the up,- pers about the lasts in the appended claims is intended. to cover broadly any suitable 'last pin and allowing it to carry the relasted shoe into the substantially vertical position shown in Fig. 7. The horn continues its motion downwardly to its initial. position.

As has been previously pointed out, the action of the machine inpushing thefshoe 0n the last broadens the forepart of the shoe Jim during the relasting operation andronse quently when the pushing pressure is relieved the shoe contracts by its own elasticity and this contraction is aided by the action of the shoe horn in pulling the hen up into place on the last so that as a result the forepart of the shoe is contracted into tight engagement with thelast. At the same time undue straining of the shoe after engagement of the toe of the last with the interior toe portion of the shoe is prevented by the friction and suction surface of the roll R. The force exerted by the friction or suction may be varied by adjusting the tension of the spring 112 so that the roll will slip as soon as the toe portion of the shoe i's seated without injury to the shoe. Furthermore, the duration of the rotation of the shoe-engaging roll is under the control of the operator, who may release the treadle 34 at any time, and it is often practicable to stop the roll when the seating of the too is complete and in this" way to avoid injury to the shoe.

The pressure of the roll against the sole pulls the toe of the sole downward relatively to the last. In relasting a turned shoe, therefore, the last is maintained out of engagement with the toe portion of the sole, until it has passed the channel lip. Thereafter the point of the last cams against the toe of the shoe to lift the sole into engagement with the last.

It will be noted that the mounting of the 1 shoe horn is such that its motion is almost exactly that of a manually operated shoe horn and in this respect is much superior to previous mountings in which such compound motion is not attained; The upward motion of the shoe horn is positive while the oscillation of the shoe horn support is a yielding motion through the spring 216. For this reason it is possible to move the arm 208 of the oscillating shoe horn support slightly in excess of the required amount, whereby the shoe horn is constantly and yieldingly urged to pull the shoe rearwardly of the last about the rear top corner of the last as a fulcrum.

The above-described method of operation lSClQllDECl in my co-pending application'No. 518294. filed Nov. '28, 1921, which is as to such subject-matter a division of this applishoes, unless such meaning is required by the context. Theterm impositive, used to describe certain means recited in various claims, is intended tocover broadly the use of a friction, suction, or other surface which mayslip under excessive resistance, as distinguished from a rigid or merely yielding connection, which cannot slip. It is not the intention to limit these claims, unless other specific limitationsappear, to the use of such a surface directly to engage the surface of the. shoe itself.
