=TofaZl whom 'it may concern:

Be it known that LCHARLES' DE MINrco,

l a citizen .ai the United States, residing at ifa Revere, inthe'l county of Suiolk and Commonwealth oli-Massachusetts, have invented cert-ain' Improvements in Lasting-Machines,

'of which the. following descriptiomin connection-Withthe accompanying drawings, is va Specification, like reference characters on the drawingsl -indicating like parts in the several figur s.

'This invention relates to last-ing machines. The machine in which the invention is herein'shown as embodied has been designed particularly for lasting the fore parts of turn shoes. A turn shoe is a shoe whichV is assembledfanddasted with thev Vflesh side of theasolevoutermost and those portions of .the'upper material on the outl f .by which the toe is lasted.

been prepared by out-ting away the mar-y ginal portion of the flesh side afound the fore part andthe shank sides to .form a thin edge and a shoulder. A slit is also usually cut into the same side of the sole and inclined downwardly and outwardly l toward t-hev shoulder to form a 'channel for receiving the seam which is to connect the upper to the sole and alip for cove-ring the seam. The. sole is arranged with its flesh' side up and is-tacked^t0 the last at several' points. `The upper materials, assembled with the linings outside and the finished Yside of the leather inside, are then adjusted upon the last and the edges drawn over the y innersole and secured. by tacks at the forward ends of the heel stiffencr and, if de? Sired', at a sufficient number of points along the shank and ball to last the sides of the shoe. 'Ihe shoe is then ready for presentation to the machine of the presentinvention In lasting a turn shoe 1t is very importantvto draw 'fthe-lining tightly, and vit is preferable that it be' drawn relativelytighter than the upper because it is essential to good lasting thatl the lining be free from wrinkles when the shoe is turned right side out. Inasmuch as the lining must be stretched while it extends over or outside of the upper and is to be reversely turned so that itextends inside of the upper on a relatively shorter line about the last, the lining should for the best result be stretched more than the upper. i In hand last-ing the operator frequently pulls the upper and the lining separately, whereby he is ablev to give -a light pull to the upper and then a stronger pull to the lining tostretch it thoroughly. It is also frequently y desirable fin lasting turn shoes, and other types of shoes as well, to pull the upper materials at one portion of the shoe more than at other portions, and sometimes to pull one shoe more than another. An important feature of this invent-ion consists in providing means by which an operator can regulate the movements of ythe machine to cause it to impart at ditl'erent times, for the purpose of drawing the marginal portion of the upper inwardly fronrthe edge of the sole, pulling movementskk ot different lengths in accordance with the requirements of the particular portion of stock engaged. by thepulling means. This regulation may be requiredto'enable the machine to give the required relative pulling strains to differentlayers ofthe upper material, or to give pulling movements of different lengths to difer-entparts of the same shoe-.0r to diierent shoes, as, for example, to givea shorterpulling movement from gripping position inwardly over the last bot-tom while a sho-rt upperfis being pulled than'when an upper of normal length is being operated upon so that overstraining or tearing of the stock may be siavoided.

In machines as heretofore .constructed means has been provided for read1ly adjusting the tension of a springA through which the movements of the grip-pers are effected for updrawing the upper. In vpractice it nia-*y be found desirable to adjust the tension of the updra'w spring Jfor reducing the updrawing strain at rthe samejtime that the length of the overdrawing moyement of the grippers is reduced and vice versa. Means is therefore provide 1n accordance sion of the updraw spring and the device for regulating the overdrawing stroke of the grippers may be actuated simultaneously. In addition to their movements for updrawing and overdrawing the upper the grippers have movements laterally for pla-iting the upper at times. This lateral movement is effected yieldingly through a sprin and it is desirable to be able to regulate t e tension of this spring readily while lthe machine is running. lFor this purpose I have provided a tension-regulating-means by which the operator may either increase or decrease the tension of the plaiter spring by asingle movement of.th hand, and the tension;regulating means is automatically locked in the position to which it is ad- 'usted. lI have also made an improvement 1n the bottom rest against which the shoe is held while being operated upon.

The several features ofthe invention, in-l cluding certain details of construction and combinations of parts, will be explained in 'the following description and pointed out yin the claims. v

In the drawings, which representa preferred embodiment of my invention in a machine of the type known as the hand method lasting machine, an example of which is shown in Letters Patent of the United States, No. 584,7 44,` granted June 15, 1897, Figure 1 is a side elevation; Fig. 2 is a perspective view of a turn shoe the toe of whichI has' been lasted upon the machine shown in Fig. 1; Fig. 3 is a front elevation of the machine; Fig. 4 is a perspective view of the plaiter-sprin adjusting means; Fig. 5 is an elevation o the machine from the -side opposite to that shown in Fig. 1; Fig. 6 is a rear elevation of a portion of the machine for the urpose of illustrating mechanism for regu ating the overdrawing movement of the grippers; Fig. 7 is a perspective view on a larger scale, showing some of the rincipal instrumentalities concerned in the asting operatlon and a shoe 1n operative vrelation thereto. Fig. 8 shows, 1n section, a

shoe, the upper of which is being pulled by the lasting grippers while the downhold is retaining the feather-edge ofthe sole against displacement by the upper being strained, and the presser occupies its retracted position; Fig. 9 'is a similar view of the shoe on a plane'nearer to the observer and shows the relative .positions of the several parts when the lppers have released the stock andthe wiper is holding the upper in the angle of union between the feather-edge and shoulder of the sole and pressing the -wire -into binding engagement' with the upper; .Fig..l0 is a side elevation showing a modification; and Fig. 11 is a detail rear elevation of parts shown in Fig. 10. Fig. 12 is a side elevation of the starting and stopping mechanism, vincluding the controlling treadle and a portion of the connection between said treadle andlthc cutting mechanism.

` The standard 2 of the machine supports a frame or head 4, in which the driving shaft v80 The grippers, which comprise jaws'14 and 16, are carried by bars 13 Aand 15, the

bar 13 being 'formed as a tube and receiving the bar 15 within it as may be seen in Fig. 7 The bar 13 is 'connected at its upper.

end by a balland socket joint with the front 'end of a lever 18, which is pivoted at 20 to Y the frameran'd is connected at its rear end with a cam 280 on the driver-shaft 6'. This connection between the lever 18 and the cam 280 comprises a block 21 pivoted to the rear end of the lever, a block normally resting on the block 21, and a'spring 23 secured at adjusted tension by a nut 24 on a rod 25. The rod extends downwardly through openings therefor inthe blocks'21 and 22 and the lever 18 to a cam roll'which stands in a cam groove in the front face of the cam block 280. Between the

blocks

21 and 22 is arranged a wedge block 26 having one or more sea-ts, as 27 and 28, shown in Fig. 10, and an operating rod 29 which extends throughA guides in the lever 18 to the front of the machine where it is provided with a handle 30. The grippers are yieldingly uplifted by means of the lever 18, actuated through the spring 23, the tension' of which is initially adjusted by the nut 24. The tension of this' spring and consequent-ly the force with which `the grippers are uplifted may be varied by moving the wedge at any time during-the operation of the machine, as, for eX- ample, when it is desired to strain more orless than usual any particular shoe or a particular portion of the upper stock engaged by the grippers. The grippers are moved downwardly by the lever 18 into position to grip the stock and are then closed by forcing the gripper bar 15 downwardly in the bar 13. This movement is eli'ecte'd by a rockshaft having the arms-32, 34, and ,journaled in bearings formed onthe lever 18, as shown most clearly in Figs. 1 and 3. The arm 32 carries a- 'yielding plunger resting on the upper end of therbar 15. The arm 34 carries a roll which is engaged by an edge cam 35, which turns the rockshaftin the direction to close the grippers. The grippers are opened, when the cam permits, byy a reverse movement of the bar 15 effected by a spring 13? 50 in overdrawingthe upper.

S6 acting cn a pin 437 vwhich extends from the bal'1 lvthrougli a slot in the bar 13, as shpwn in Fig. 1. f

The grippeis are given movements out- 's wardly fronifthe machine 'for drawing the upper over the sole on the bottom of the last, and to this end the bar 13 is extended p through a block guide 40 which is supported *by the forked front end of `a longitudinally movable slide rod 42, which is mounted in the frame and carries a roll'44 for engagement with a cam 46 by which the slide rod 1s moved rearwardly to drawthe grppers toward the machine and into their gripping 15 position. Reverse movement of the slide rod 42 for actuating the grippers to pull Athe upper over the last is effected by a spring*-n actuated arm 48, the spring for which may havejits tension varied by means of the arm 49 which is secured in adjusted position by a pawl and ratchet, as shown inv Fig. 5. As has been explained7 it is important to regulate the pull effected by the grippers in accordance with the different requirements of different shoes and diierent portions of the upper material of the same shoe, and for this purpose means is provided which is under control of the opera-tor and which can be adjusted while the machine is running for controlling the movement of the grippers to pull the upper materials over the last. The mechanism by which this is accomplished may be varied, but in the machine herein shown a readily operable device is arranged for limiting the range of. movelment of the grippers by adjustably limitlng the movement of the slide rod 42. To

' this end a rockshaft 50 is arranged in bearings in the frame, as shown in Figs. l, 3, 6

40 and 10, and has an arm 5.2 connected to a slide 54 which is forked at its free end to embrace the slide rod 42. The slide 54 is arranged tobe guided between arear face 55 of the frame and a bracket 56 and to exv tend more or less between said face 55 of the frame and the head 45 of the slide rod where it vforms a stop to limit positively the normal length of movement or stroke of the grippers inwardly over the ledge of the last rThe forked ends of the sliding stop 54 may \be of uniform thickness, as in Fig. 6, or` may be relativelyl thin at their end portions, as'shown in Figs. 10 and 11, so that when. said'end portions 55 are interposed a limitedtdistance between the head 45 and the face 55 theyvill shorten the range of movement of the grippers to a certain extent. When the 'slide is further introduced between the head and frame the thicker portions will shorten to a greater extent the stroke of the grippers for-v pulling the upper over theilast. 'It will be observed that in thus regulating the move-- ment of lthegrippers for pulling the upper materials over the bottom of the shoe the gripping position remains the same and the outer limit of the movement is varied.

For actuating the rockshaft 50 there is shown in Figs. 1, 3 and 6 an arm or handle 58 appliedh in convenient position to be reached by the operator. A spring 59 connected to the arm and to the fixed part holds the arm and parts controlled by it in the positionsl to which they are adjusted.

In Figs. 10 and 11 is shown a modification in which the slide 54 is arranged to be actuated simultaneously with the adjustment ofthe wedge block 26. Ari-arm 60 replaces the handle 5S and is connected by a link 61 with one 'arm of an elbow lever 62 fulcrumed on the lever 18, and having its other end. joined to the wedge block` by a link 64 so as to be actuated by the slide rod 29.` The connection between the arm 60 and the rockshaft 50 is made yielding through the spring 65 so that movement of the operating handle may and if the head 45 of rod 42 prevents the immediate adjustment of the stop slide 54 when the slide rod 29 is moved the spring will effect such adjustment when the vrod 42 is retracted. lVith this construction, the

force of the spring 23 through which the uplifting movement of the grippers is effected and the extent of the forward movement-of the grippers may be varied by the same adjustment. It sometimesoccu'rs that in the rapid reciprocation of the slide-rod 42 fortake place at any time, I

wardly and backwardly the grippers are drawn backwardly by their momentum beyond their gripping position adjacent to the edge of the last and therefore do not prop- .erly grip the stock and sometimes strike against other parts of the machine. To pre- 'vent this overthrowing of the grippers the slide rod 42 is shown as provided with an adjustable stop 43 arranged in position to engage the frame yot the machine if the rod is carried backwardly too far by the momentum of the moving parts. l

Mechanism is provided, which is arranged to be rendered operative at the will of the operator, for giving to the grippers movements Jfor plaiting the upper. This mechanism includes means for moving the grippers laterally from one side of the median line of the machine, in which they usually operate, to positions at either side of the median line. To this end a knee lever 68 .c provided, Athe'rear arm of which has an inclined guideway, las shownin Fig. 5 receiving 'a roll 71 on'a verticalrod 70 which, through a bell-crank lever 72, controls the position of a sliding collar 74 on a sleeve shaft 75. The sleeve shaft receives a rocksha-t 76, which has a stud Tia-extending through a spiral slot 79 in the sleeve shaft and intp the slidingr collar 74. Movement of the collar 74,orwardly or backwardly, by the knee lever 68 therefore adjustsI the rockshaft 76 which carries on its front end a pinion 80 that meshes with a rack on a segmental block 82. The segmental? block is guided in a rocking head carried by the sleeve shaft 75. The sleeve shaft and its head 85 are continuously oscillated by a lever 86, pivoted to the frame and having on one end, see Figs. 3 and 5, a sector and on its other end a roll standing in a groove in the side of t-he cam block 35 by which the ippers are closed yas before described.

ovement of the knee lever actsthrough the parts` described to set the segmental block 82 in the center, or at either side of the center, of oscillation of the head 85. The grip ers are connected with the segmental loc `82 for movement laterally and also rotatively for plaiting the upper when this disposition of the upper material is required to ltakecare of the fullness of the marginal portion ofthe upper materials about the toe' of the shoe. lThe segmental-block 82 may be regarded for convenience as an actuator which when set in the center of vpscillation of the head 85 is inoperative, and iwhile set on one sidel of that center will move the grippers in one direction and While set on the other side will move the grippers in/ an opposite-direction. The segmental block has,-

pivotal connection'with a link 90 joined by a connecting rod 92 with a plunger 94 supiortedin bearings in the guideblock 40` eretofore referred to as receiving the grippers. A yielding connection is arranged between the plun er 94 and the guide block in order thatl t e-force may beyieldinglytransmitted to, the grippers for moving them laterally. To this end the plunger'is connected at 95 with the lower arm of a-T-c shaped lever 96 thatis fulcrumed at 97 to the-guide block. 40 and supports a crossbar 98. The guide block carries a plunger 99 acted upon by a spring 100, the tension of .which is determined by a cap 105, which is adjustable in the block 40. Itwill now be understood that movement is transmitted anism through the lever 96 and connections to the spring 100, and by the spring, yield'- -from the plunger 94 and its actuating mech'- for mpving the latter laterally firstv in oney direction and then in the reverse direction.

in time relation with the closing, uplifting,` and overdrawing movements of the grippers which are effected by cams on the same shaft 6 asvthe cam from which the lateral movements are produced.

The direction of the irst movement of r the grippers, toward `one side of the median line of the machine vwhile holding the stock whereby a plait is formed'in one direction or toward the opposite side tocarry the Stock in that direction to formia plait, is

"provided on one side with a rack and a pinion 106 is mounted in the guide block 40 inengagement with the rack. The pinion is carried by a shaft 10S on which is an operating arm 110 and a ratchet wheel 112,

while a spring-pressedpawl 114 is mounted on the guide block in position for engaging -the ratchet wheel to lock the parts in the position to which they are adjusted for determining the tension of the spring 100. The operator can readily increase the ten- -sionof the spring by pressing down the operating armv 110, While by depressing the tail of the pawl to free the ratchet the eX- pansion of the spring may be allowed to act automatically to raise the cap 105 any required distance forreducing the tension of the spring and therefore-varying the force with which the grippers will be moved laterally. It should be understood that these adjustments may be made while the machine is running and in accordance with the requirements of the work at any particular time,-as, for example, by the condition o r nature of the stock to be gripped and plaited. The extent of the lateral movement of the grippers toward either or both sidesof the median lineof the machine may be determined by an adjustable collar or collars 115, mounted on one .of the arms of the guide block 40 which are movable endwise in the forks of the slide lrod 42.

sol

For turningthe grippers in time relation `with their lateral movements to facilitate the plaitingof the stock the link 90 is connected to a lever 120 which is mounted on an ladjustable fulcrum block 122 and joined yieldingly at its upper end to a connecting rod 124 that carries a rack bar 125 meshing -With rack teeth formed on the peripheral upgripper bar 13, as illustrated away about its margin to form a shoulderv and a thin or feather edge o'n that face over which the upper is laid. The stitches 4Which connect -the upper to the sole"pass through the upper and into the sole in the angle i'io formed by ,the shoulder and feather-edge,

passing thence through the portion of the sole between the shoulder and the base of the channel and 1'oe'ing laid in the channel,

lian4 toe of y 'anchored y where they are covered by the channel lip. It is desirable for the purpose of preparing the shoe for .the sewing operation to force the upper material into the angle of union formed by the feather-edge and shoulder. Also, as'herein shown, the upper is temporarily secured in lasted position about the the shoe by a binder of wire which is `the;` uller-over, the Wire being drawn snugly ind the overworked upper material of the sole. To avoid against the shoulder f danger of this -wire slipping up out of bindf between with Ya presser 130 connected by ing position, itjis very important that the upper 'be forced into said angle of union the feather-edge and the shoulder the wire. To this shown is provided thus forming a seat for end the machine herein the' foot 132 of a longitudinally moving slide 134 which is guided in the frame, as shown 111 end of a lever 1,35. .Jhe lever is pivoted to an adjistarble fulcrum block at 136 and s actuate om a gro v in a cam 138v on t e oilkr V""130. The cam is formed to advance the presser over the shoe after the grippers have pulled the upper and before they open to release it and to cause the presser to force the upper snugly into the angle of union.

In addition to the presser 130 the machine is preferably provided with a wiper 140 which is rigidly connected to the frame of the -machine and forms a stationary block projecting forwardly vto the limit of the for- Ward movement of the presser 130. The shoe is fed along with relation to the wiper While held against it, so that it serves to crease the upper into the angle and orm it to the desired position. The presser and wiper also serve to seat or to force into binding lposition the'wire by which the upper is held. For this purpose their ends are ofv a suitable thickness to engage the wire w, which, passing from a reel 142 through a suitable tension device 144 and a guide 146, is fastened to a tack, as at t in Fig. 7 and held taut in the path of the reciprocating presser and between the end of the stationary wiper and the upper material which stands against the shoulder lof the sole. These relations are shown in Figs. 8 and 9, Fig. 8 being a sectional view'in a vertical plane passing betweenithefpresser and the wiper, and Fig. 9 being a sectional view in a plane passing vertically through the stationary wiper. When the lasting is finished the wire is anchored to a tack' t on the farther side ofthe sl oe and securely holds the upper until the 'shoe is ready to begsewed, by which time the upper material will" have become suiiiciently set in its lasted position so that it will remain sewed. .The

tothe foremosttack inserted by,

bolts 131 to Figs., 5 and 7, andl connected to thelower equipped with a contact piece or workgengaging foot which is rotatable about an axis perpendicular to the face of` thel sole, and as herein shown thefoot 150 has a serrated lower face and is connected by a vertical pivot stud 151 with the shank of thea-.down-v hold, which, in turn, is clamped in a bracket extending forwardlyl from the; frame. v The bottom rest also preferably .v supports the downhold 152 which extends over the shoul' der of the sole and bears on the featheredge to hold it from being displaced by the upper during the operations of' working the upper into lasted position. The' downholdisslidably mounted in a guidewayin the upper face of the shank ofthe bottom rest and is adjusted and moved toward and. from an operative position by a pinion 154,'engaging recesses in the body of the ,downhold as lown in Fig. 7 and actuated/by a. handle In the usfof the machine al shoe in the' hands of the operator will be presented bottom uppermost to the' edge restB and bottom rest 10, the rotatable foot 150 of the bottom rest engaging the sole of the shoe, and `the downhold 152 -will be advanced into position over thel shoulder vof the ,sole into engagement with the y feather-edge. The binding wire willy be ydrawnythrough 'the tension device 144'and'anchored to the tack t. The upper materials, including the upper stock and the lining or either o these,

VIf the upper material is short, so -that it cannot be pulled bythe normal stroke of the grippers `Without. danger of drawing it out of place on the lastfonis weak, so that it is liable tobe torn, or if the upper alone is tobe pulledwithout the lining, then the slide 514 willbe moved range of the overdrawing movement of the grippers, and preferably the wedge y26 will be out of operative position, as. shown in Fig. 1. With the arrangement shown in Fig. 1 the adjustment of the slide*r 54 and of the wedge 26 is effected by their

respective handles

58 and 30, while in the construcwill be adjusted simultaneously by means of the handle 30 and the connection between the wedge and the rockshaft 50. ,If a strong pull upon the stock is desired, as, for example, in a case Where the upper materials are inelastic or` wherev the lining wedge 26 may` be adjustedto=increasevthe tension of the spring y will be positioned out "of: the `path of the head 45 of the overdraw rod 42, whereby the force with which the grippers are uplifted While beingU bottom rest is preferably` will be increased/andthe -grlppers mayhave their full strokeior pulling the upperv over as may be required, will.A then be presented in into operative position vfor shortening the.

The pawl will automatically lock the spring at any tension ceeds the'wi're, h aving been anchored to the tack t, is drawn from the reel through the `tension` device and the guide 146' and wrappedl about the toe of the shoe. The reci'rocat'ing presser 130 forces the upper rm into the` angle of lunion between the preferably .presses the 4wire against' the upper to seat it securely in holding positxon.-A The wiper 140 remains continuously in engagement 'with and serves to form the'upper into the desired position and to hold the upper from slipping back until the shoe shall have been turned `far enough for the wire to bind the ul per firmly. The rotatable foot v150 of the' ottom rest facilitates the turning 0f the shoe for presenting Vsuccessive portions of the lupper to the grippers and 1t -will-be observed in Fig. 7 that the foot lli of the lbottom rest may be so positioned that it engags the v.sole approximately at thecenter a out which the shoe is turned in lastin aroundthe toe end of theshoe so that ere is little or no occasion for movement of the foot of the bottom rest over the surface of the sole. .When the lasting is completed to the farther side of the' shoe the wire will be anchored to the tacks t and` then cut from the strand of wire senting it tothe cutting' device.

The cutting device preferably comprises a stationary cutter 160 and a swinging cutter A162 pivoted at 163. A rod 164 connects the upper arm of the swinging cutter bar with a lever 1 5 fulcrumed at 167 and connected b a 1in 168 and rod 169 with a treadle 1- 0 which "is ulcrumedI at'171.

.The treadle -also has connection by means of a rod '172 with a starting and stopping mechanism shown in Fig. 12 and which may of any usual .or preferred form. vThe connection betweenthe treadle and the cutting device and the connection between the ltreadle. and the lstarting and stopping 00 mechanism are preferably so arranged relatively that.- one of vsaid parts may be actuated independently of the other,` and as herein shown there issufficient lost motion y between the treadle and the starting and 66 stopping mechanism to allowfof the cuttingby simply pressing down either the handle' Ifor laying'it in position to which it is adjusted.
