To all whom it may concern":

Be it known that I, ERAs'rUs E. VvINK LEY, a citizen of the United States, residing at Lynn,,i:-1 the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Automatic Shoe-Machines; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ape pertains'to make and use the same.

The present invention relates to machines for use in the manufacture of boots and shoes.

In the method of making'welt shoes devised by me the ends of the Welt on a welted shoe are butted and an ou'tsole having a rounded heel, a rounded and skived shank and a block forepart, is applied to the welt i be produced between the welt and outsole.-

butted shoe in such manner that the rounded heel registers with the rounded heel of the insole. The ends of thewelt. and the shank skiving adjacent the heelv seat terminate a predetermined distance from the rear ends of the insole andoutsole respectively in order that a smooth well fitting joint may Preferably, although not necessarily, the predetermined distance hereinbefore referred to is such that the breast of the heel of the finished shoe bisects the joints between the outsole and the welt asitis found that with this arrangementthejpressure of the heel acts to effectively l'lOld. the outsole and the welt in theirjointed relation. In order to carry out my method of making welt shoes v in a commercial manner Ifhizvedeviseda system of automatic machines for rounding and skiving the outsole, for -butting the welts and for laying the outsole pro erly on the welt-butted shoe. In the best orm of welt butting machine hereinbefore devised by me the welt butting operation is'automatically I performed, afterv the welted shoe has been located at the welt butting station by the operative who depends entirely upon. his judgment in adjustingthe back stop with which the machine is provided so that the ends of the welt maybe butted at the proper point. In order to successfully carry out my novel method ofmaking welt'shoes it is necessary for the operative to adjust the back stop so that thedesired portion of the shoe bottom, usually the breast line of the insole, will register with the welt butting instrumentalities at the welt butting sta- 7 tion. Specifically it'is-found impossible for an operative to determine by inspection the breast li-neof a welted shoe and then adjust the back stop in the welt butting machine so that theshoe is located at the welt butting station with the actual breast line of the shoe registering with the welt butting instrumentalities. v v The object of the present inventionis to produce a welt butting machine by which 'cept to place the welted shoe. inthe machine andremove it therefrom after the completion of the welt butting operation.

the welts of shoes of the same size and style To the accomplishment of this' object, and s'uch'othersas may hereinafter appear, the

features of the invention relate to certain parts hereinafter described and then set forth broadly and in-detail in theappended claims, which possess advantages which will be apparent to those skilled in the art.

Thevarious-features of the present invention will be bestunderstood from an in- .75 devices, combinations and arrangements of.

E. Winkley,

- 1,029,837, June 18, 1912. The welt butting instrumentalities carried by the welt butting head are operated in the same mannerto slide in Ways 2, (Figs. 6 and 7), formed in a bed 3 (Fig. 1), projecting forwardly from the supporting frame 4 for the welt butting head 5. The table 1 is held in posi- 2; tion upon the bed 3 by cover plates 6 carried of the shoe is located adjacent the welt but by the bed and arranged to over-lap the table 1. The table 1 is automatically moved during the operation of the machine from a position convenient for the insertion and re- .25 moval of a shoe, which position is herein after termed for convenience the jacking station, to a position where the breast line ting instrumentalities which position .is herein termed for convenience the welt butting station; To this end the rear end of the table 1 is provided with a bracket 7 (Fig. 3) upon which is pivotally mounted one end of 1 a short link 8 the other end of which is pivoted to an arm 9 (Fig.1) loosely mounted upon ahorizontal rod 10 carried by the frame 4. Pivotally mounted-upon the rod 10 is a second arm 11 which is connected by a link 12 with an arm 13 pivoted intermediate its ends on a pin 14 carried'by the head 5. The upper end of the arm 13 is provided with a roll 15 which is engaged by a groove formed in a cam'16 carried by a cam shaft 17 journaled in the head 5. The cam shaft 17 is 'driven from a suitable source of power througha pinion 18, on a driving shaft 19,-whichme'shes witha gear 20 on the shaft 17. In order to actuate the arm 9,

-whei1" the" arm 11 is oscillated on the rod 10 byf the connections from the cam 16, the arm 9 carries a perforated lugf21 which embracesa;.rod 22 carried by alug23' formed on the 1 arm 11. The lugs 21 and 23 are normally held. contact by a spring 24 coiled around the 22 and interposed between the lug 21 and. a suitable adjusting and locking device 25'. With the construction described the work supporting table 1 is brought fromthe' shoe jacking station to the welt butting station when the clutch (not shown) which controls the driving shaft 19 is thrown-into op--- erhtion by the operative, After'the welt butting operation the work supporting table 1 is returned to the shoe jacking station at which time the clutch hereinbefore referred to is automatically-tripped and the machine brought to rest. The provision of the yielding connection between the arms v9 and 11 permits the extent of movement of the table 1 toward the Welt butting station to be limited independent of the cam 16 so that the shoe may be variably located at the welt buttin station. In the embodiment of the invention illustrated in the drawings the independent means for limiting the extent of movement of thetable 1 toward the welt .butting station takes the form of a pair of cooperating stops one of which, a stop 26, is

carried by the bed 3 (Figs. 3 and 7) and the other one of which, a stop 27, is carried by the sliding table 1 (Fig. 3); p

In order to support a shoe the table 1' carries a slide 28 arranged to slide in ways 29,

beneath cover plates 30 secured to the table. The slide 28 carries a vertical hollow post 31 which slidably receives a vertical spindle 32 provided at its upper end with a last pin '33 (Fig.2) arranged to engage the pin socket in a last 34 which carries a lasted and welted shoe (Fig. 3). The supported shoe is normally maintained elevated by a spring 7 35 coiled around the spindle and interposed between the bottom of the hollow post 31 and a shoulder 36 formed on the spindle. The u wardv movement of the shoe under the in uence of the spring 35 is limited by a plate 37, arranged to engage the heel seat of the shoe. The depending shank 37 of the plate 37 is pivotally mounted between the arms of a yoke 38 on a standard 39 carried by the slide 28. The shank 37 of the plate 37 is provided with a horizontal arm 40 (Fig. 6) which carries a screw 41'the head of which is embraced by a slot 42 formed in a block 43 on the upper end of a vertical rod 44 s'lidably mounted in lugs 45 and 46 formed on the standard 39. The plate 37 is normally maintained in position to limit the u ward movement of .the shoe by a spring 47 coiled around the rod 44 and interposed between the lug 45 and a pin 48 on the rod.

The pin 48 also acts as a stop and cotiper-' "ates with the lug 46 to limit the movement of the plate 37 under the influence" of the spring 47.

In order to lower the supportedshoe and swing the heel seat engaging plate 37 trans- ":versel'y of the shoe to permit the unob- 'str'ucted removal of the shoe from the last pin 33.and the placement of another shoe thereon the machine at the jacking station [is provided with a sliding block 49 (Fig. 4)

mounted to slide. in vertical ways 50 formed in the bed 3. The block 49 is bifurcated and is mounted on the upper end. of a vertical rod 51which is connected to a treadle and-a tension device (neither of which is shown) the construction being such that the block 49 is normally maintained elevated by the tension device but may be depressed against the pin 53 and lower the shoe against the tension of the spring 35. To swing the 'plate 37. transversely of the shoe when the rod51 is depressed the bed 3 carries a pivoted arm 55 (Fig. 3) which is provided at its free end with a roll 56 arranged in the' path of movement of a slot 57 formed in a block 58 carried by the lower end of the heel seat engaging plate rod 44. When the shoe is moved away from the shoe jacking station a the arm 55 is supported by a finger 59 (Figs.

3 and 4) projecting from a block 60 adjustably mounted on the rod 51. When the shoe is at the shoe jacking'station the roll 56 is supported by its engagement with the slot 57. As soon. however. as the block 49 is depressed a sufiicient distance to strike a screw 61 (Figs. 3 and 4) adjustably carried by thearm 55 the latter is actuated in a direction 4 Y to lower the' rod 44 and thus swing the plate 37 transversely of the shoe. After the shoe is removed from the spindle another shoe is v placed thereon and the treadle rod 51- released -to the influence of the tension device.

' As the block49 rises the plate 37 gradually swings transversely of the shoe under theinfluence of the spring 47 the construction be ing such that the plate is repositioned over,

the heel seat of the shoe as the latter is being elevated so as to limit the upward movement of the shoe under the influence of the spring 35. It is apparent that with this construction the welt crease of shoes of all sizes and styles are uniformly brought into the same plane.

The'other arm of After the shoe is placed in position on the last pin 33 and clamped beneath the heel seat engaging plate 37 the operative moves the slide 28, which carries the last pin 33 and plate 37, and the slide '7 9, which carries is pivoted to the cover plate and the other table 1 by the -tinuedf rearward movement of the slide 79 istable 1 the Slide 103 being end of which is pivoted to the slide 28. Pivoted on the lever 88 at 89 is an arm 90 one end of which is normally held pressed against a perforated lug 91 formed on the lever 88 by a spring 92 coiled around a rod 93, secured to the arm the lug 91, and interposed between the lug 91 and a nut 94 on the rod. The other end of the arm 90 is pivoted to one end of a link 95 the other end of which is centrally pivoted on an. arm 96 pivoted in turn at one end to a bracket 97'secured to one of the,

cover plates 30. The other 'endof the arm 96 is provided with a longitudinal slot 98 which embraces a vertical pin 99 secured to the slide 79. The arm 96 is also cone nected bya link 100 to a hand lever 101 pivoted at one end on a bracket 102 secured to one of the cover plates 30.

By manipulating the hand lever 101 the moved toward the ,heel engaging finger 62. It willbe apparent from an inspection of Fig. 2 that the arrangement of the connections for actuat- I v ing the jmove differentially toward the heel engagslides 28 and 79 will cause them to ing finger 62 the construction being such that the slide 79 carrying the toe engaging finger 63 will'move through a greater distance than the slide 28 carrying the clamped shoe in substantially the ratio 5 to 1.

As soon as the counter of. the shoe strikes the finger- 62 the'finger 69 through the connections described is elevated from between the rolls 71 and the slide '28 is locked to the jamming of the rolls. Conpermitted by the yielding connection be-- tween the lever 88 and arm 90. When the finger 63 strikes the toe of the shoe the finger 83 is elevated and the slide 79 is locked to the table 1 by the jamming of the rolls 8 1.

- In order to control the position of the stop '27 in accordance with the length of the shoeas determined by the length measuring fingers 62 and 63 the stop 27 is carried ilpon a slide 103 (Figs 6 and 7)- mounted to. slide iit ways 1045";formed in the bottom of the retained in position in the waysfby cover plates 105 carried by the table and arranged to over-lap the slide. The slide: 103 is provided with rack 90 and embraced by' the movements of the stop 27 and longitudinally of series of holes 119 formed in the arm 111.

shoe interposed between the measuring fingers 62 and 6.3. In the embodiment of the invention illustrated in the drawings the 'connect-ions between the stop 27 and the slide 79 are such that the stop 27 is adjusted by the length measuring movement of the slide 79 in the ratio that the length of the heel seat of the jacked shoe bears to the length of the shoe. That is, the stop 27 is adjusted under the influence of the length measuring mechanism so that when the table 1 is moved toward the welt butting station the stop 27 will contact with the stop 26 and limit the movement of the table teeth 106 (Fig. 3) for a portion of its length when the breast line of the shoe has registered with the welt butting station.

As well known to those skilled in the art shoes are designed in such manner that there is a predetermined ratio between the length of the shoe and the length of the heel seat. This ratio, however, varies for the difierent sizes and styles of shoes. In order therefore that the machine may invariably position the breast line of shoes of all sizes and styles at the welt butting station the connections between the stop 27 and the slide 79 are adjustable to permit the ratio between the slide 79 to correspond with the known ratio between the length of the heel seat and the length of the shoe of-the size and style which the operative desires to insert into the machine. To this end the arm 111 is provided with a segmental slot 114 (Fig. 3) which embraces apin 115 forming the pivotal con-. nection between the am 111 and the link 112. By varying tlile position of the pin 115 t e tween the movements of the stop 27 and the slide 79 may be varied as desired. To guide the operative in changing the ratio'the arm 111 is provided with a scale 116 which registers with an index 117 on the link.1 12 to indicate the desired ratio. To look the arm 111 and link-112 in their adjusted position the link 112 carries a pivotally mounted spring pressed plunger 118 the head of which is arranged to engage any one of a While the invention has been explained in connection with my system of automatic machines for carrying out my method of making welt shoes it will be apparent to those skilled in the art that a machine embodying slot 114 the ratio bethe features of the present invention may be used to butt the welts on Welted shoes in factories where my method of making welted shoes is not employed. Many shoe 5 manufacturers do not appreciate the importance of positioning the joints between the Welt and the outsole beneath the breast of the heel in the finished shoe. Others appreciate the importance of holding the outsole and welt in jointed relation but take the extreme View that the forward nail at each breast corner of the heel in the finished shoe should penetrate the outsoleand the welt at the jointed points. Still others while employing my method incorporate freak heels in their shoes. The lengths of these heels have no relationto the lengths of the heel seats on the outsoles so that the breast of the heels do not register with the designed breast line on the outsoles. To adapt the machine to the varying conditions in the different shoe'factories the illustrated embodiment of the invention is provided with an adjustment" for arbitrarily changing the point at which the welt is butted. To this end the stop 26 is provided with wings 120 (Fig. 7 whichslide over a plate 121 on the bed 3 and also with a block- 122 which slides in a slot 123 formed in the plate 121. The stop 26 is clamped in adjusted position by a bolt 124 carried by the block 122, which is 1 arranged to jam a washer 125 loosely carried by the shank of the bolt between the bottom a 1 of the plate 121 and the head of the bolt. To A $5 aid the operative in making the adjustment the plate 121. is provided with a scale 126 (Fig. 3) and the stop 26 with an index 127 {to indicate the desired position of adjust-f ment away from the standard position.

.40 a The mode of operation of the embodiment of the invention illustrated in the drawings 1 maybe briefly described as follows: During the time that the welt butting instrumentaliv .ties are thrownout of operationthe table 1 '4 5ica'rrying'the work supporting devices is held j'- "stationary at the shoe jacking station. To

remove the welt butted shoe the operative I. first throws'the handle 101. to theright (Fig;

2) thereby separating the length measuring fingers 62 and 63. The treadle rod 51 is then depressed which lowers the spindle 32"and swings the plate 37 transversely of the shoe thus permitting the unobstructed removal of the welt butted' shoe and its replacement byanother shoe upon the lastsupporting pin- 33. When the new shoe is placed in position uponthe pin 33 the operative first releases the treadle rod 51 topermit the springs 35 and 47 to elevate the shoe and swing the plate 37 into its operative position the construction being'such that the plate is re-; turned to its operative position in t1me to.

' limit the upward movement of the shoe under the influence of the spring 35. The operativenext throws the handle 101 to the fistantially .as described. v

-2.'A'- weltj'butting 1nachine,'fhaving-,v innbutting station, and. automatic means for in- I ment of the stop 27 being proportional to the length measuring movement of the finger 63in the known ratio that the length of the heel seat on the measured shoe bears to the length of the shoe. The operative now throws in the clutch which controls the main driving shaft 19. .The table 1, carrying the shoe, is then withdrawn from the shoe j acking station and moved toward the welt butting station until the stop 27 strikes the stop 26. The table is then held stationary with the breast line of the shoe registering with the welt' butting instrumentalities at the welt butting station. The cycle of operatlons fully described in the patent-hereinbefore referred to now follows whereby the welt is automatically butted. At the end of the cycle of operations involved in the automatic welt butting operation the tablel is, returned to the shoe-jacking station, the

clutch is automatically tripped and the machine is brought to rest.

While the invention has been illustrated and explained in connection with a machine for butting welts it will be apparent to those skilled in the art that certain features of a construction may be advantageously embodied in other machines for operating on partially finished or finished shoes.

. n will also be clear to those skilled inthis class 'of machines, with the general objects of the '"present invention in view, that changes may be made in the details of struc- 'ture, the described and illustrated embodi-. a ment thereof being intended as an exploita-' tionof its underlying essentials, the features ,their true J whereof are definitely. stated in scope in the claims herewith.
