v Be it known that l, CHARLES F. ADAMS, a citizen of the United States, and resident of Swampscott, county of Essex, Common wealth otMassachusetts, have invented an improvement in Lasting Machines, of which the following description, .in connection with the accompanying drawings, is a'speciication, like characters'on the drawings rep` resenting like parts in each of the several This invention relates to lasting machines general type shown in the patent to Y Chase No. 571,509 and the-patent to Scarlett and Adams 1,313,121. One prime object o the present invention is toprovide improved mechanism for manipulating the clamping and holding devices of the shoe with the last therein with reference to the wiper heads at the' toe and heel of the shoe whereby the shoe may be pressed against the .wiper plates to the required degree at a preliminary stage of the lasting at the heel, and then given a iinal lasting pressure, all by the manipulation off devices operable in an especially convenient manner and responsive to the will of the operator to an exceptional degree. A urtherfobject is'to provide improved and simpliiied means forr pressing and fitting the heel oi the shoe into the heel pad therefor in the heel wiperhead, this being accomplished in the present embodiment with a combined upward and-yielding backward movement particularly' effective for the purpose in view. A still 'further object is to provideV means whereby the clamping devices for both toe and heelportions oi the shoe may be simultaneously tripped.- and released, or only one of such devices. tripped at will. rihe foregoing and other objects and advantages oi the invention will more fully appear from the following ldetailed description, and the distinctive features, of novelty will be pointed outinthe appended claims.

"The heel/andl toe wiper heads may-be of `usual or any suitable construction comprising .heel and toel `-pads and wipers, a conventional form 'oflheel wiper head" being indicatcd at 5, this headv being mounted on' a'carriage 5ZL adjustable along the ways 4 by means of an operating screw 5bswiveled in the 'frame and engaging a nut ot ysaid carriage, said screw having jat its outer end an operating hand wheel 5. The wiper head 5 is equipped with a. suitable concave heel pad 6.k lA toe wiper head is indicated at 7 also slidably fitted to the-slide waysl` and having Irigidtherewith'witha web or like connection a guide-sleeve and holder 8 for a toe presser head to be further described later. The heel jack pin or spindie Qispivotally mounted at 10 on the top of stoutrod or'post 11 which is in sections and equipped with a suitableyturnbuckle without Ydisturbing the operating connections thereto. The lower end 111L of the post or rod 11 is pivotally connected at 13 to one of a series of spaced apart holes 14 in a bar 15.

riChe bar 15 constitutes a floating type of lever having no single permanent fulcrum but slidably guided vertically with a capability or" tilting, byl 1n-upright post 16 secured to the frame at that end of bar 15 adjacent the rod 11, this post having a stop pn- 17 to limit the downward movement of said lever end. The other end of said lever is lilrew' e vertically guided with a capability of tilting by a higher upright post 18 having a coil spring 19 encircling the same and adjustably pressed down on to the end of said lever by` an adjusting nut 20 threaded on the top portion of said post. A stop pin 19a is provided to limit downward movement of bar 15 on rod 18. rllhe bar 15 has valso pivoted thereto at one of' the holes 14 a bar 21 having a head 22 in its upper end formed with a relatively deep cup recess 23 into which iits the lower end of a rod 24 which carries the toe rest. The rod 24 is slidably fitted through a sleeve 25 .that is threaded into a barrel 26, said barrel having at its upper end a head 27 slidably fitted to the ways 4. Thel barrel 26 houses a compression coil spring 28 abutting the adjustable sleeve 25 and pressing against a stop collar 29 carried at the top of the rod 24 and limitingthe upward movement of said rod bearing the toe rest. The collar 29 has formed therewith an upright sleeve 30 slidable through the head 27 and having threaded thereon an'adjustable upper stop collar 31.r The .sleevey 30 has fitted therein a depending stem 32 bearing at its top a head 33 in which is journaled a roll 34 of rubber or the lilre constituting` the immediate-toe rest element. interposed between the head 33 (and the collar 31 is a coil spring 35 tending to hold said head pressed outward. Spring 35 may, under certain conditions, be dispensed with. The barrel 26 is connected through a two-part rod 36 equipped with a turnbuckle connection 37, to the sleeve 8 which bears the toe presser head, and as stated, is rigid with the toe wiper head 7- this permitting an adjustable setting of the toe rest 34 with reference to the toe wiper headV 7 and to the toe presser head to be now described'. Siidably fitted vertically through the sleeve -8 is a bar or rod 38 having at its top a bearing sleeve block 39 with an interposed spring 40 reacting to normally press said rod and bearing sleeve block yieldingly upward. The bearing block 39 is mounted on the bar 38l witha capability ofl small angular movement with reference thereto, this n being` permitted by a pin and slot connection 39a between said block and bar, the slot in the block 39 being a little elongated laterally to permit ay limited pivoting of said bearing block on said bar, this being for the purpose of permitting the presser foot 70 piece 50 later described to be adjusted laterally enough to center it with reference to the toe of the shoe. The sleeve bloclr 39 has slidably fitted therein a tubularrod 41 bearing at its inner end a head 42 and having 75 enclosed therein a tension coil spring 43 arranged to normally draw the head 42 into contact with the end of the sleeve 39 as shown in the drawings, the tube 41 having along slot 44 at oneside thereof` to aflord 80 clearance for a pin 45 constituting an anchor for said spring'. The head' 42Y is equipped with a vertical bore 461m which is slidably fitted a pin 47 held for limitedivertical movement therein by a pin and slot con- 85 nection 48, a spring 49 being housedin the upper portion of saidbore and reacting to press thepin=47 downward. The pin 47 has mounted upon its lower extremity a toe presser piece 50 comprising a. substantially 90 flat work engaging plate and a sleeve portion 53 providing a 4socket of somewhat larger diameter-than pin 47 andV in which the latter is seated. Across pin 51 extends loosely through apassage 52 in pin 47 and 95 engages at its opposite ends in openings in the walls of sleeve 53. By this arrangement the presser piece is enabled to tilt about pin l51 andy to move slightly in an up-and-down direction as well as to swing with 'head 42 100 as above described. y

The postor rod 11 has removably Secured thereto at an intermediate point a stout leaf spring which is bent obliquely outward and downwardly from its securing point on 105 I said rod. The outer surfacefof this spring is engaged by a roll carried by a bracket 56 held at the inner end ofa screw 57 threaded through a nut member 58 fixed to the fra1ne,`said screw being equipped with a il() suitable operating handle 59, at its outer end. For holding the spring 54 pressed against the roll 55 a tension coil spring 60 is provided anchored at one end -to the bracket 56 and engaging the rod 11 at its 115 other end. The rod 11 passes through a slot in the bracket 55 which serves as a guide therefor'and thus by adjusting the screw Y 57 the jack pin 9 may be set in proper posij tion with reference to the heel pad V6 and so 120 as to permitthe proper action ofthe spring 54 for yieldingly pressing the heel into said seat as later more fully "described The lever bar 15 is engaged from below at an intermediate point by a cam 61 having a 12E, curved toe portion 62 extending toward the toe operating mechanism and forming part ot a lever 63 pivotedto the bed at 64, said lever extending in the opposite direction where it is engaged by a tension spring 65 130 operated .trip lever having a fixed anchorage bracket 56 and normally retaining said cam in an inoperative position, the outer end of the lever 63 also having connection with an operating link 66l whose other'end is connected with a lever arm 67 ulcrumed'to the rear of the `frame bed at 68 and having rigid therewith'a treadle lever 69 extending to the front of the bed where it is equipped with a suitable treadle 70. The treadle lever 69 has pivoted thereto at 71 a latch dog 72 yieldingly drawn into engagement with a series of ratchet teeth 73 on a fixed downward projection of the frame by a coil spring 74. The latch dog 72 has a rigid therewith a projecting toe member 75 engageable by a 76 in bell crank form having a toe portion engageable by a depending bar 77 pivoted to the frame at 78, this bar having an upward extension above said pivot to be by a manual trip connection to be presently further explained.

For operating the .toe presserhead with its presser member 50 and also to a limited extent the toe rest 34, a Second treadle lever 79 is provided'pivoted to the rear of the frame bed, as shown on 68 which serves as a 69. The lever 79 is normally drawn upward by a tension coil spring 8O engaged therewith and anchored to the frame. This lever is connected to operate a drawlink 81, this draw link having an intermediate pivot 82 and having fixed at its upper end a head 83 iitted to vertical slide ways 8&1 of a housing 85 fixed to the main frame work. The head 83is provided with a recess constituting a horizontal slide way 86 in which is guided lfor sliding horizontal'movement a bar 87 p formed with an elongated slot 88 in the portion thereof that is guided through the head 83, an outward extension of said bar being fixed to the lower end of the upright toe presser carrying rod 38 as indicated at 89. Y t

The depending stem 2a of the toe rest has fixed thereto a bar 90, this bar having a slotted portion extending into thev housing 85 in parallelism with the bar 87. The bar 90 is slidingly guided in horizontal ways of ahead 91 also guided to slide vertically in the housing 85 and lying face to tace with the Vhead 83. The heads 83 and 91 are provided with co-operative shoulders V92 so formed that the head 83 may move upward leaving behind it the head 91 while the head 91is prevented by the engagement of said shoulders from moving up past the head 83, and thus a downward movement of the head 83 under the action of .the treadle constrains the head 91 to move downward with it. .The head 91 is quipped with a hub 93 extending into an elongated slot 911l of the housing 85 and thus the range of movement of the head 91 is limited inv either direction by the as shown to the the same pivot shafty ulcrum for the leverv vertical extent of said slot. The

bars

87, 90

which`as stated are arranged ink parallelism are.4 adapted to be broughtiac'e to 'face when the heads 83,91

this postion a pin 95 housed in a hollow ot are directlyopposite Aand* in the hub 93 and in the bar-90 is adapted to be projected by rest 341; to partake of the movement oi the toe presser head at this time..vv The-pin 951s y provided with a stem 97 having a head 98,..- and overfthis stem is itted the widenednand end'99 vof a trip lever 100.y

vertically slotted The trip lever 100 is pivotedto the housing 85 at 101 and its freeextremityis extended Vto the right `(Fig. 3) toV a point adjacent the upwardfextension ofy the bar 77 as indicated at 102. .At this point along the machine a pusher' pin 103is vslidably itted in the' frame and equipped with an '.enlargedoperating head 104 in positionl and adapted to be l engaged by theknee of the operator-,acoil "9o. to normally. hold the pin 'in an outward prospring105 being disposed around said pin'y jected position. The inner end of the pin 103 within the frame plate 2 has fixed thereon a block 1.06 recessed toreceive andfholdV in co-operative relation the end of the lever 100 and also pivoted as indicated at 103?- to,l j

of the .pivoted bar 77.` Thus the upper end heel'treadle `lever 69 to be assuming the locked in lowered position by the detent 72 andk also the presser` foot 50 to bev held locked Ydownward by the: engagement o the pin 95 as'seen in Fig. 7, the y:toe .treadle 7 9 being thendepressed, push pin 103,* both these devices will'fbe tripped, i. e., the jack pin 9V will be per-I mitted to lower and atthe same time the presser foot 50 will be released Jfor elevation by the spring 40. Means is ralso provided whereby the presser/foot 50 may be tripped to permit it to rise'withoutreleasing the lever 69 and the jack pin. :For this purposer 1 provide a second push pin 107;.having a upon pressing in the head 108 similar to the head 104. and also in convenient position to' be reached by the knee of the operator. This pin which is also' normally 'spring pressed outward engages the -lever 100 at an intermediate point andis adapted on being pushed into, swing said lever so as to withdraw thepin 95 without affecting the block 106 and thus not tripping the detent 72. The webor'plate portion 7a connecting the base oftheto'e wiper head 7 with the bearing sleeve 8. is equipped with a removablepin :109. This pin is adapted to.l 'engage selectively any-one'o' aseries of spaced apart holes 110 in oneside` .of the'. slide way 4, thus locking the toe wiper head and the toe presser piece .orY in any one of according to,

presser'fo'ot 50 J a series ofselective positions.- thej'class of the shoes' to bej lasted. It will be understood that" the reason for the provision of the

bars

87, 90 with elongated slots is so as to permit the action of the locking pin or bolt 95 in'any position ot adjustment ofthe toe wiper head and also in any relative position of adjustf ment Yof the toe rest 34 as effected by the turnbuckle 37. I preferably mount an upright post 111l having a reduced upper end 112 adapted to receive the last, in a lug 113 at a side of the machine frame, so that the operator can place the shoe onthis pin for any desired' manipulation duringor' incidental to the operation offlasting and have it out of the way of the operating devices. Y

' In accordance with my invention jack pin 9 is preferably held on its pivot 10 with a bias towards forward tilting' such as to cause the toe portion of the shoe to tilt. somewhat downward to bring it against thetoe rest when positioned on saidj ack pin. For

this purpose I provide a springfpressedhead' 9a' (F 1g. 13) having its top inclinedasseen" at 9b and Dressed against the bottom surn Vface of the head of the jack pin 9 bythe coil spring 9c housed 1n the top of the post Y 11. Thus the jack pin is normally held tion of the post 11.

tiltedforward to a small extent asv deter mined by the angle of. the incline 9b, but with a capability of being readily swung backward as required in the manipulationo'f the shoein the lasting operation.

In Fig. 12 I show a modiiication of the' invention lwherein instead o'thaving a separate controlling screw 57 and hand wheel 59 for adjusting` the. upright post 11 of the jackpin, the bracket 5G?L corresponding to the. bracketiG is mounted rigid with, and is controlled from .the heel wiper carriage 5a. For this purpose the wiper carriage 5n has depending therefrom land rigid therewith an arm 1111, the lower end of which is formed with a sleeve 115 in which is adjustably clamped a bar 115 which has secured at its inner end the bracket 56a as .by means oit a clamp device 11'?.V The bracket 56@ in this form -may be equipped with a roller abutment 55 to cooperate with the spring 54 just as in the first described form. The bracket 56a has rigid therewith and depending thorefrom an arm 118 equipped at its lower end with an inward extension having a bearing collarA 119 pivotally secured thereto and adapted to guide and position the lower por- In this form the lower end of the bar 11 instead of havinga fixed pivotal connection with the bar 15, has instead a bearing block 13l to slidably engage the top of the bar 15, said block being held in operative relationY to said bar by the sleeve 119 and being slightly moved along Ythe barz as the heel wiper'carriage 5f" is adjusted, so that the relation ofthe jack pin 9' tothe heel pad@l is preserved.` This construction is ofadvantagejin that it permits the entire'heel controlling and heel wiper mechanism to moved as a unit by manipu-` lation ofv the hand wheel 5C, as is required for moving the shoe'lorward to a'small extent after the preliminary lasting steps, to bring the Vtoe' of rthe shoe fully intothe toe wiper seat for the completion of the toe` lasting. To permit Vsuch small lateral'ad'- justment ot the jack pin as may be requisite for properly centering the heel transversely, in this form of the invention the connection at 117 may be formed to 'permit a slight. swiveling at' this.. point to the extent necessary for this purpose.

I consider the construction of the toe rest 311 as a roller, in connection with the de-v scribed provisionfor: adjusting the heel wiper head and the jack pin 9 forward simultaneously, .especially asin F ig. 12, to be'avaluable and important i'eature of the invention since thereby after the preliminary stage of the lasting operation and after the toe issemilockedon the restl 34, the shoe with the heel wiper mechanism operatively engaged therewith may be movedbodily 'torward to the small extent required by manipulation of' the hand wheel 5C so as to bring the toe up closely into the toe wiper pad and into proper operative relation with the toe wipers for the final operative vengagements therewith.

It will beunderstood that the provision of the lost motionshown between'the end of the stem 24a-nd the-bottom of the cup socket 2S is for the purposeofpermitting the described small downward movement of the toe rest 34 in the'preliminary stage of the lasting operation. The described adjustment of the stop collar` or nut31 on the stem 30 permits a yielding setting of the toe rest so that the spring 35 may be Vput incompression to a desired variable degree at the initial stage of the'lasting operation and prior to compression ofthe springQ.V

The operation of the machine is Vas follows, it being understood that the wiper heads and other operative instrumentalities have been set in proper relative position for working upon the particular size and shape ot shoe to be lasted: Y

he shoe when placed upon the last ,supporting spindle 9 will, if the'parts are properly adjusted, have its heel seat surfaceV slightly below the heel wipers and spaced a short distance from the heel pad carried by the heel wiper head. L'Ihe operatork now" places his foot upon treadle'70 depressing the same slightly, thereby lifting the jack post,fwhich at this time lis free to rise,the lever 15, thek left hand extremity off'which is resiliently held downwardly against the pin 19L by means of thel spring l19, .turning about the pin 19a as a fulcrumy during this movement. it the same time the post is caused to swing backwardly under action of f hand lasting the cam 54, it being understood that this cam, being removable, may be interchanged for cams or different shapes. Such movement of the jack post brings the rear portion or the shoe iirmly against the heel pad and substantially in the plane of the heel wipers, the wheel 5c being manipulated to move the shoe forwardly until its tip lies closely adjacent but out ot contact with the toe pad carried by the toe wiper head.

Ii after bringing the 'presser root down to operative position it is found desirable to change its position it may be released ,for readjustment'by actuating trip pin'107. l

By reason of the spring abutment of the last supporting'spindle 9, the shoe is caused at this time to bear somewhat heavily upon the toe rest 34, whereby the shoeis subjected to a preliminary clamping action. Furthermore, bythe employment or the wedge member 9@l the last supporting spindle is prevented from swinging 'rearwardly beyond the vertical to as great an extent as it is possible for it to swing orwardly,this arrangement being particularlyy desirable in connection withlasts in which the rear'porltion is hinged to the forward portion and which might buckle under the lasting pressure it the last pin were permitted to swing 'far rearwardly.

The pulling-Over tacks at the tip O the toe are now removed and the upper leather at the tip is stretched iirmly by means of pincers, vand the wipers are drawn close up to the toe, the upper stock being spread outwardly over the wipers.

The operator now slides theV presser toot 50 outwardly over the toe portion of the shoe and dopresses the treadle 79, thereby bringing the presser foot down onto the surface .of Athe shoe adjacentthe toe and within the lip of the innersole.

As the presser foot 50 is brought downwardly into contact with the shoeit is free to rock slightly about the pivot 51, and also to move vertically upwards due to the 'enlarged opening 52 in which the pin -51 is mounted, thus accommodating itself to irregularities in plane or' the shoe sole, while the operator may, by oscillating the sleeve 39 about its mounting upon the upper Yend oi the rod 38, swing the presser root into proper lateral relation to the toeregardless or the style of last employed.

In depressing the treadle 7 9, the springs 40. 419 and 35 are compressed, these springs all being relatively lighter than the spring 2S which supports the toe rest. As the toe presser foot moves downwardly depressing' theY spring 35 or the toe rest as above noted, the shoe moves downward slightly and the toe portion is caused to bear rmly against the toe pad while the upper stock is tightly stretched by its engagement with the wipers.

time the jack post can movement of the treadle 7 9;and when spring 35 has become substantially fully compressed, the locking pin 95 snaps into the slot 88 and locks the toe presser root and the toe rest together.

Continued downward Amovement of the treadle 79 thereupon tends ,to move the toe rest and toe'presser root rocked about its supports suiiciently to cause an even lbearing or. the wipers around the toe, whereupon the wipers are moved all'the way in and the shoeis moved bodily forward into closev contact with the toe pad by manipulation of the hand .wheel 5c. The toe ytreadle is now released whereupon. the

spring pressure or spring 28 'orcesthe .toe rest 34 upwardly holding thelshoe forcibly against the under surface of the wipers@l i The operator now adjusts the heel portion or the shoe by further manipulation or the treadle 70 until the proper wiping level, which may have been ldisturbed during the toe lasting operation, is attained, whereupon the heel wipers .are brought partially in, and as the operator addsgradual pressure to the treadle 70 the wiper head is rocked to level the wipers relatively to theheel seat: and then the `wipers are drawn completely in, thereby wiping in the heel portion or the upper. f j Atthis point of the operation while both heel andtoe portions areheld beneath the wipers, the'operator forces treadle 7 0 downwardly to its Jfurthest extent. As at this only riseV very slightly the lever 15 tends to turn aboutk the p1n17 as a ulcrum, compressingspring 19, and the brought into contact with vthe Ilower end of 23 at the'upper endl of the rod21fis L rod'24 whereby the toe restis lifted positively to-put an additional pressure against the toe wipers, it being noted Vthat at'this time both'the heel and toe. are4V underpositive pressure which is substantially equal- V ized 'by the rocking lever 15.

While the parts are under sure, wheel 5 is operated kto bring inal pressure between the heel pad and the shoe, and while this pressure is `.maintained the treadle 70 is released and the: heel wipers are retracted, the operator now -taclring the heel in the usual manner. Y y

rl`he toe wire is now fastened at` one side of the toe, the wheel 5 manipulated' `to slightly release :the pressureonthey toe pad and while the operator holds theftoe treadle 7 9 depressed he retractsthe toe wipers sunt-.1

this final prescient-ly to permit placing the wire around the toe. The operator then moves the wipers inwardly to wipe in the wire and fastens it to the second tack. He now retracts the toe wipers, releases the presser foot by means ot the trip pin 103 and removes the shoe from the machine, thus completing the operation.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and l therefore desire the pres- 'ent embodiment to be considered in all respects as illustrative and not restrictive, re'- erence being had to the appended claims rather than to the foregoing description to indicate the scope o1 the invention.
