THOMAS H. SEELY, OF MALDEN, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A COR- IPORATION OF NEW JERSEY.

LASTIN G-MACHIN E.

To all whom it may concern:

Be it known that I, THOMAS H. SEELY, a

citizen of the United States, residing at Malden, in the county of Middlesex and State ofMassachusetts, have invented certain Improvements-in Lasting-Machines, of Which the following description, in connection with the accompanying drawings, is-a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines, and more particularlyto that type of lasting'machine Which'is adapted to Work on different portions of the upper materials successivelyvas described in United States, Letters Patent, No. 58 4,74; 4,dated June 15,-

In machines of this type, devices, such as pincers, are actuated "to grip and pull or updraw the upper materials and overdraw or lay them overupon the innersole, and a Wiper is given movement to engage the upper materials and press or Wipe them smoothly upon the. innersole. The upper materials are secured lasted position by tacks, which are fed singly into an aperture in the Wiperf prior to eachadvance movement thereof and driven by tack-driving means at the conclusion .of the-Wiper ad vance. Machines of this type are also pro overlay theupper materials, and at such time the gripping and'overdraw movements of the pincers may conveniently be dispensed With as may also their plaiting movement, thus relieving the machine of this work, decreasing the machine vibration, and the Wear that Would otherwise-ensue. At other times, itmay be desirable to c0ntinue the gripping and overdravv movement of the pincers without the plaiting move: ment Where the fullness of stock is not eX- cessive, in which case the pincers Will be givena straight updravv and overdraW action.

During the lasting operation on this type of lasting machine, and the driving of the fastenings or tacks, the shoe is ordinarily held by both hands of the operator, While Specification of Letters Patent. Patented Sept. 10, 1918. 7 Application filed November 8, 1915. Serial No. 50,309. I

his foot maintains the starting and stopping treadle; depressed to continue the machine in operation. It is ineXpedient for him to release the shoe or to disturb the position of his foot While the operation of lasting continues, and yet it is desirable that he have personal control of the pincer gripping and overdra-W movements, and be able at Wlll to suspend or introduce such movements, as Well as to suspend or introduce at Will the pincer plaiting movements.

' It is an important object of the present invention, therefore, to improve lasting machines of this type by securing therein the results indicated, andto this end an important feature of the invention comprises the provision in a lasting or like machine adapted to work on different parts of the upper materials successively, of means for suspending or introducing at ill the pincer gripping and overdraW movements independently of other parts of the machine and While such parts continue in previously es tablished operative relation. By the provision of such means, the operator may,

While holding the treadle depressed to con- 7 tinue the machine in uniform operation, and While still holding the Work With both hands, either suspend or introduce the pincer movements and render them operative or-inoperative in placing the upper ma- I terials in lasted position Without at the same time changing the relations of other parts of the machine.

Another broad feature of the invention consists in the provision of improved means movable at W111 to a posltion to control some of the pincer movements to another position to control other of sand pincer movements.

On starting the lasting operation in this type of lasting machine, it is desirable that the pincers should grip and overdraw the upper as the machine makes its first revolution, and thereafter that such gripping and overdrawing action of the pincers be continued. or discontinued iat the will of the operator according to the condition of the work. Another feature of the invention, therefore, consists in means for insuring that the pincer gripping and overdrawmovements will be effective on starting the machine in combination with means .for rendering ineffective or continuing at will the pincer movements following the :first cycle of themachine operation.

Theabove several features of the invention and others not hereinbefore specified as well as certain novel constructions and combinations of parts, will now be described in connection with a ma'chine'of the type referred to in the aforesaid Letters Patent, but itis to be understood that the invention. is not to be considered. as necessarily restricted in its application to this type of machine, nor to the particular details shown and described by .way of explanation of the invention. 7

Fig. 5 is a side elevation on an enlarged scale, showing certain of the parts illustrated in Fig. 1, pertaining more particu-. larly to the pincer control mechanism and tack saver; V e V Fig. 6 is a perspective detail of parts relative to the tack separator; and f Fig. 7 is a perspective detail, partly in section, of the tack carrier slide and wiper. mechanism. V p 7 Mounted upon the column 1 is thehead frame 2 which supports the main driving shaft 8 carrying the pulley 4 which may be connected to any convenient source of power for applying necessary rotative movements to the shaft 3. I j

Pivot-ally mounted on the head frame at. 5 is the pincer updraw" lever 6 which may be actuated from a slide 7 by means of 'a cam block 8 secured to the main shaft, the construction being such that as the main shaft 3 is rotated, the updraw lever will be oscillated upon its pivotal mounting 5 in the head frame.

Connected to the updraw lever 6 is the: pincer bar 9 carrying at its lower end one of the pincer jaws 10. Extending through the pincer bar 9 is the pincer closing rod 11 carrying the other pincer jaw 12, said pincer closing jaw being operatively con nected to an arm 13 mounted upon the shaft 1 1, Fig. 1.

Loosely mounted upon the main shaft 3 is the cam block 15 from which the shaft -1 1 derives. its movements as common" in this type of machines, for causing the p1ncers to grip and release the stock, substantially as more fully disclosed in the patent heretofore mentioned, and as set forth in the patent to" Bates, No;1,029,840, dated June 18,

- From the construction thus far described it will be apparent that upon rotation of the main driving shaft 3' the pincer jaws will be given their updraw; movements and that they wilLbe closed and opened provided the cam block 15 is operatively connected to the main driving shaft 8, otherwise, while the plncers may continue their updraw movements, they Wlll remain open.

In order to lay the upper materials over the innersole, the pincers, in this type of machine, are given an overdraw movement.

after they have been closed upon the stock.

This overdraw movement is effected by a spring-operated thrust rod 16, Fig 1, C011? trolled by a face formed on the rear side of the cam block 15, and connected at its forward end to the'pincer bar, as usual in. this type of machine, the construction being such that when the cam block 15 is rotatably connectedfto the main shaft 3, the pincers in addition to their gripping and 'updraw movements, will be given an overdraw move ment to position the stock over the innersole, ready to be secured in position by suitable fastenings. ll

In lasting certain portions of the shoe, where the stock is excessively full, owing to thecontour of the last about which .it is to be placed, it is desirable to plaittheupper in order that it may be more smoothly ma upon'the innersole, and to this end it has been customary to give the pincer-s, in'addi tion to the r gripping. updraw and overdraw movements, aplaiting movement. This is effected in the present machine, from'the' cam blockl5 which is provided with .the usual track in its frontQsidefronl jwhich is actuated a lever, not sh own,..to" oscillate a' structionof the means; for "imparting the plaiting movement tot/he pincers is not here illustrated and descr bed 'in detail, as it is 'sleeve shaft 17 and a rocker 18. The cone 7 is sufficient soto lay the upper upon the innersole that the fastenings may be insertedto secure the upper about the heel seatin lasted position. It is consequently important to suspend the pincer grippingand overdraw, and plaiting movements at such times, thereby relieving the operator from thenecessity of causing the shoe to dodge the pincers on each'cycle of the machine operation. At other portions of the shoe, however, where the fullness of the upper materials is not excessive, it is desirable to glve to the plncers their grlpping, updraw, and overdraw movements in a straight line, and at such times it is neces- .sary to suspend the pincer plalting movements. At still other times, in lasting that portion of the shoe where the fullness of the upper is excessive, the pincers in additionto their gripping, updraw, and overdraw movements, should be given their plaiting movement, either to the right or left.

During the lasting operation, however, the operators hands are both employed in holding and moving the shoe for the action of the lasting devices upon successive portions of the shoe. His foot is likewise employed to depress the treadle that the machine may continue its operation. It is essentiahhowever, that the operator have under his controlj these various changes in the'pincer movements to" bring them at will into accord with the character of the work pre sented by the-different portions of the shoe,- and this he should be able to do without" changing the established operative relation of other parts of the machine, and without disengaging his hands from the shoe or altering the position of his foot wlth relation to the depression of the treadle.

I is especially advantageous to the-aboveends,l because it enables the operator to change To this end, the present invention contemplates means for enabling the operator to dispense with or introduce the pincer closing and overdrawingmovement independent of' any change in the relation of other of the machine parts, and while stillmaintaining his hands engaged with thework and his footholding the treadle-in-its unchanged depressed position. -The knee-controlled means the operative condition of the pincers by" merely swinging the knee to one side or the other or holding it in the central position, and this he may do without changing-his position with relation to the machine or altering-his foot control of the treadle or his hand control of the work.

To provide these characteristics in the machine, the cam block 15 is loosely mounted upon the main shaft?) and is adapted to be operatively connected thereto by a clutch.

In the present instance, the cam block 15 has pivotally mounted thereon at 19, a latch 20 provided with a lug 21 adapted to engage a recess 23 formed in a collar 24 secured to the main shaft 3. A spring 25 secured to the cam block normally acts upon the latch] 20 to move it ina direction to cause the lug 21 to engage the recess 23 when the latch is free to respond to the demands of'the spring, the construction being such that when the lug 21' and recess 23 are engaged,

the cam block 15 will be caused to rotate with the main shaft and when such parts are disengaged, the cam block may remain idle while the main, shaft continues to rotate.

A clutch controlling lever 26 is pivotally mounted at 27 on-the head frame and its upper portion is provided with means for disengaging the latch from its connection with the collar24- when said leveris moved to bringsaid means into operative relation with the latch andto permit engagement of the latch and collar when the said 'means is moved out of such relation. In the pres ent instance of the invention,'the upper end of the lever 26' is provided with a block 28, Fig. 3, having a cam portion 29 adaptedito engage a lug 30 projecting at the side of the latch 20, the construction being such that if the upper portion of the lever 26 is moved into position toward or adjacent the latch f while thelatter and the connected cam block lug 30 will engage the cam portion of the block 28 and cause the latch to be lifted to thereby disengage the lug 21 from the recess-23of the collar, and thereupon the 1 cam block 15 will be disengaged from opera- 11 5 tive connection with the main shaft and be brought to rest. Opposite the cam portion 29 of the block 28. is a spring catch 31,'the shoulder 32 of which will engage belowthe lug 30 when the latter rides over the cam portion 29 of the latch, and prevent rebound. 7 v Y The clutch controlling lever 26, above its pivot 27, is connected to a rod, 33, Figs. 2

and 4, the other end of which enters a longitudinal recess 3formed in a plunger '35, and bears upon a light spring interposed between the end of'the rod 33 and the end wall ofthe recess, a pin and slot'connection' 36between the rod and -'plu1'1g'er, permitting limited longitudinal movement of the rod 15 are-rotating with the main shaft 3, the 7 Thus ,it will be seen 0 a V..

The plunger 35 has a head portion 38, Fig. 4, adapted to be engaged by a cam face 39 on the end ofa rocker pivotally mounted at 40 and connected by a rod 41 with the treadleoperated starting rod 42, the construction being such that upon depression of the treadle, as usual in this type of machine, the starting rod 42 and'rod 41 will be moved upwardly, thereby turning the rocker to cause its cam face to move the rod 33 against the tension of the plunger spring orv to the left,'Figs. 2 and 4, and place the upper end of the clutch-controlling lever 26 in position to disengage the latch 20 from the collar 24, should the lever remain in such position when the machine makes its first revolution after starting. that when the machine isat rest, the latch 20 is left in position to operatively connect the cam block 15 and the shaft 3 .so that on thefirst revolution of the pincer will be 'given' its but at the completion of the'firstrevolution, the latch will'be disengaged from operative connection with the collar 24 and thereafter the pincer-gripping and overdraw movements will be suspended unless modified, as will be hereinafter more fully described.

This characteristic action of the machine is desirable because without it the operator would have to wait over the first turn of the machine before he could get a pull by the pincers, and inasmuch as the lasting. operation is customarily commenced at a part ofthe shoe'where the upper materials are to be updrawn tail a-loss of time 'andinefi'ective operation of the-machine. j

The lower end portion of the clutch-controlling lever 26 is provided with a pin or lug 43 which, in connection with means to.

be presently'described, and under the con-u trol of the operator, mayfurther determine whether after the first revolution of the ma-:

chine, the'pincers shall continue their gripping and overdraw movements, or shall suspend the same.

In the present instance of the invention,

the pin or pro1ection 43 is provided with an angular portion movement with relation thereto, is the knee lever 45, Fig. 1, carried by suitable bearings 46 for rocking movement with respect thereto," .Qne'end of sa d knee 1ever45 is prof Thev plunger the V end and overdrawn, this would en- 44 preferably formed as vided with a knee'yoke 47 which may be appropriately connected to the knee lever adjustably, as indicated at 48. At the other side of the pivotal connection of the knee lever 45 with the column 1, said lever is provided with a diagonal. way or inclined cam 49 adapted to engage a pin or roll 50 secured to a rod 51 which may be guided in a lug 52 for vertical movement with respect thereto. At its upper portion the rod 51 is provided with a head 53 pivotally connected at 54 with a rocker 55 mounted torock upon a fixed pivotal support 56 carried by the head frame. The rocker 55 at its other end portion has securedto or formed therewith, a finger 57. In the present instance of the invention, said finger'is preferably secured to the rocker by a clamping bolt 58. The finger 57 is provided with a recess 59 corresponding in general shape to the shape of the angular portion of the pin 43 and in the present instance of the invention is substantially shaped. From the construction thus far described, it will be seen that upon rocking movement being imparted to the knee lever 45, the rod 51 will be raised or lowered, according to the direction of the rocking movement and perforce, the rocker 55 will be rocked upon its pivotal mountin}; 56 to either raise or lower the finger 57 relatively tothe end 44 of the pin'43. When portion of the pin 44 and corre, sponding V notch of the finger 57 are in opposed relation as indicated in Figsrl and 5, the clutch-controlling lever 26 will be moved by the rod 33 when the machine is operating to carry its upper end portion toward the latch 20 and effect disengagement of said latch from the collar 24, to thereby suspend the operation of the cam block 15, and perforce, the pincer-gripping and overdraw .movements which are derived therefrom.

7 opposite the V lug of the'finger43, and the finger will in this disposition of parts, move the clutch-controlling lever 26 out "of enga'gement with the latch 20'to thereby permlt the latch to operatively engage the cam' block 15 with the main shaft 3, and perforce, cause the "pincer-gripping and overdrawmovements.

From the construction thus far described, it will be seen that whenthe machine is at rest. the latch 20 is in position to operatively engage the cam block-'15 with the main shaft 3, and when the operator depresses 125.

the usual treadleto start the-.machine, thelatch-controlling lever 216 will be moved into position to engage the latch and free-the cam block when the machine has made one,

revolutionmld the Pincers; have been given 139 one gripping and overdraw movement.

[Should the operator: determine at-this time to continue thegpince'r-gripping and overdraw movements, he will after depressing the treadle to'start the machine, move the knee lever to the right or left to thereby cause the finger 57 to move and retain the ."clutch-controlling lever 26 out of engaging position with the latch 20 asthe cam block continues its rotation. ,iIf, however, the operator determines that, after the first revolution of the machine and the pincergrlppmg and overdraw movement incident thereto, such pincer-gripping and overdraw movements shall be suspended, he will not move theknee lever, but permit it to remain in central position with theV notch of (the finger, 57 and the V end portion of the pin 43 in opposed relation, which permits the upper end of the clutch-controlling lever26 to be held bythe plunger spring 34 in clutch-disengaging position.

*The described control of the pincer-gripping and overdraw movements by the knee lever orothe'r equivalent means actuated by the body of the operator other than his hand or foot, is not tied up to any other elements of the machine construction so that such other 1 elements may remain in previously disposed relation while the operator changes at will the operative or, inoperative condition of the pincer-gripping and overdraw movements. r 7

As hereinbefore noted, it is desirable at times to plait the upper during the pincergrippmg and ove'rdraw movements, and at other times to suspend such plaiting movement of tllepPlIlCGI'S whlle still contlnulng their gripping and overdraw movements to therebyeffect a straight pull upon the upper 'materials; and to this end, the present as will now be described. 7 p Mounted on the rocking sleeve 17 of the usual 'pincer-plaiting mechanism, is the col invention con-templates that the same means for controlling the pincer-gripping and over draw movements as by the knee lever,

shall be available to the operator for controlling the plaiting jmovementsof pincers,

lar60 which, by its "movement to the right or left, determines the direction andamount .ofplaiting movement givento'the pincers and by its central position, suspends such plai'ting'movements. The details of the pincereplaiting 7 mechanism are not here1n shown, because such pincer-plaiting mechanism'forms no essential part of the present invention, and is well understood by those skilled in the art.

The yokefil for moving the sleeve to the ri ht or left or to central position, is pivotally mounted upon the head frame, and

in the present instance of the. invention, upon the same axis 56 as the rocker 55, Figs.

1 and 5. Said yoke 61 is connected to the sleeve 60 by the pins 62 which travel in the pathway 68 formed centrally of the collar 60. The yoke 6l-exte'nds beyond its pivotal r nounting toforin an arm 642 Whiclr'carries a pm or roller 65. The pin or roller 65 engagesfa 'cam slot formed inthe head53. This cam slot is formed with inclined: end portions 66 and, 66 as indicated in Fig. 5, which, when thefknee lever'is turned in one or the other directions, will act thro'ugh the pin or roller 65 of the yoke to movethe yoke longitudinally of the rocking sleeve 17 in one direction or-the other, according to whetherthe knee lever is swung to the right or left to thereby determine the direction and amount of the plaiting movement of the pincers. v

.As' before noted, it is desired at times to give the pincers their gripping and overdraw movements while su'spendingthe operatlon of the plnc'e'r-plaitlng mechanism in order to give to the pincers a'straight pull;

and at other times it is desirable to give to the pincers not'only their gripping and overv draw movements, but also their plaiting movements' To this end, the cam; slot in the head 53 has a short, straight portion 67 which permits the knee levertobeswung to the right or left a short distance without turning the yokeupon its pivot, such dispressions 68 adapted to engage the apex of the l en d 44' of the 15111.43; the construction being such that when the knee lever has been swung to the right or left'a sufficient distance to insure the gripping and overdrawing movements'of the pincers, but not sutIiciently far to introduce the plaiting movements, this fact will bemade' evident by the shallowjrecesses 68 engaging the V endof the pin 43. Should the operator desire at anytime to introduce theplaiting movements of the pincers while continuing their gripping and overdrawing movements, he has only to move the knee'lever a greater distance in order'to ca'use'the inclined p'ortions 66 or 66 of the camjsl'ot to move the yoke either to the right or left, according V to the direction of plait desired, andsuch movement 'merely gives additional movement to the finger, 57 without changing the pincer-gripping and overdrawing operation.

When the pincer-gripping and overdrawin movements are suspended, the upper materlals are laid over the edge of the inner- This wiper cure the upper in lasted position, are supsole sufficiently by a wiper. may be of any character suited to its purpose,but as illustrated in the present instance of the invention, the wiper is mounted for movement in an inclined path relatively to. the edge of the shoe to conform to the direction of the plaits in the upper materials, as fully described in the United States Letters Patent to Bates, No. 1,029,840, dated June 18, 1912. While this character of wiper and its action may be advantageously employed in some cases, the invention herein is not dependent upon this particular form of wiper, but such wiper may be omitted and dependence placed upon the V usual tack carrier 'or tack block for wiping the upper materials into lasted position, as will be readily understood.

A lever 70, Fig. 1, is fulcrumed at 71 to a suitable bracket mounted upon the head frame, and at its upper end engages the cam slot 72 of a cam .7 3 secured to the main shaft. The lower end of the lever 7 0 is connected to the slide 7 4 which constitutes the tack carrier slide, the construction being I such that upon rotation of the main shaft 3, the lever 70, and perforce, the tack carrier slide, will be given suitable reciprocating movements.

. The tackcarrier slide 74 carries the tack carrier 75 having an opening 7 6 therethrough, for receiving a tack from the tack feeding means, and presenting the tack to the driver. recipro'cated to carry the tack carrier back and forth, and when the tack carrier reaches asuitable position in its rearward movement, a tack is transferredfrom' a raceway into the aperture 7 6 of thetack carrier and then the tack carrier is moved forward into V which engages a whlch is under 'proper' timed relation to the operation of and may act to wipe the overthe pincers,

' then forces the tack carried in the aperture of the tack carrier through the upper materials to secure them in lasted positionf, f Pivotally mounted at 77 Fig. 7, of the tack carrier 75, is the wiper 78 which will partake of the reciprocating movement of the tack carrier7 5; andin order that the wiper 7 8 may be given the inclined direction already described, the rear end portion of the wiper is provided with a roll 79 U guide 80, the position of I the control of an arm 81, Fig."7,'connected to the swing member 82, Figs. 2 and 5. The swing member 82 is pivoted at 83' and at 84. it is connected to the means for controlling the plaiting mechanism wherebythe direct-ion of the U guide ber 89, separator 86.

The tacks or fastenings which are to sethe tack separator 86 by the rack and segment 87, 88, respectively,1the latter being formed as part of a yielding member 89, as usual, and normally under the influence of a spring 90 against'the tension of which the yielding member 89 may be appropriately moved by means of a cam 189 on the tack carrier slide and a roll 190 on the yielding memto effect reciprocation of the tack vention, the yielding member 89 is composed of two parts, the segment carrying portion and the operating portion 91, said two portions of the member-89 being substantially of the construction heretofore common in this class of devices, and the construction being such that while the tack separator 86 may be recipr'ocated to detach a tack from the raceway and deliver it to thetack carrier when such separator movement is not obstructed, yet when there is obstruction to the tack separator movement, the two portions of the member 89 may-yield to permit the ack separator to; remain at rest. The general construction and operation of the parts relating to the tack separator and tack supply may be as heretoforecommon in the art.

Changes may of course be made in the various constructions and details of the invention as hereinbefore explained, without departing from the true scope thereof as pointed out by the claims; but the described construction has been found a convenient and good,practical 'form of the invention.
