ing boots and shoes, constructed and arranged for operation all substantially as hereinafter fully described reference being had'to the accompanying sheets of drawings, in which- Figure lis a front view. Fig. 2 is a plan View, with a last and upper of a boot or shoe in position to be lasted. Fig. 3 is a longitudinal vertical central section on line 3-3 Fig.

' 2. Fig. A is a cross section on line 4 4 Fig.

l looking to the right. Fig. 5 is a detail plan view of one end below line 5-5 Fig. l. .'Fig. 6 is a detail plan view to be hereinafter referred to. Fig. 7 is a plan view below the parts shown in plan view in Fig. 6. Fig. S is a detail elevation of.some of the operating parts enlarged.

In the drawings A represents a body'or frame supported by a central cross pivot or screw bolt B between two vertical arms C of the vbase plate D which can be secured on any suitable support, the bolt passing through a longitudinal slot E in the body as shown in Fig. 3, by which the body can be moved forward and backward, and by tightening the bolt hold it at such place. At each end of the base plate Figs. l and 3 is a projection Fup through which extends a screw G, having ahead a for turning it, on which screws the endsb of the body A rest and bear for it to be adj usted'as to lits angle of elevation onits pivot, andwhen adjusted by turning up the screws accordingly be held firm in such adjusted position. y

His apin on which the heel J of the last K is placed by` its socket d as shown in Fig. 3, which pin is screwed at e into a block L pivoted atf between two arms g of a bracketM having a spindle or rod N adapted to move horizontally in a socket h of the body, the block extending down a short distance below its pivot as atyl against the inner `side of the rlower end of which is arranged to abut an.

armPon a horizontal' pivot .Qin :the body,

and having secured to a forward extension of the pivot a handle R for swinging the same. This spindle or rod N extends beyond the opening or socket h in the body and has on its outer end a screw nut and around S which abuts against a shoulder it of the socket and against an inner screw nut T on the end of the spindle in the socket, the screwing on or off of which nut T increases or reduces the tension of the spiral spring S.

After the last is placed on the pin by swinging the handle R up, its arnrP will be moved against the lower arm j of the pin block L and cause it and the heel pin H to swing and the last to move forward for the purpose hereinafter described. f

U is a block arranged to slide toward and from the last pin in a dove-tail groove r in the body having a downwardly projecting central lug t through which screws horizontally a screw V having a head uwhich abuts against the end fu of the body and an inner shoulder 'Lo in a socket .fr in the end which allows the free turning of the screw, but pre# vents its longitudinal movement, so thatl in turning the screwin either direction the block this spindle in the socket h is a spiral spring U will be moved forward or backward along wardextension z between arms a of the block U so it can swing up and down thereon within lcertain limits, an open slot Y engagingwith f,

a cross screw bolt A limiting its downward movement, but allowing it to be swung upward a short distance as shown in Fig. 3, and' to be secured in its adj usted position by tightening up the screw bolt A.

The forward or left 'hand end of thev plate W is much thinner than therear portion b which thinner portion is'in the form of two iat arms B having inner curvededges mak-V vcurved arms C D which cross each other as at E being cut away at such place to pass by each other and then extend forward over the IOO plate arms B as shown in Fig. 7. These arms C D beyond their junction are angular in cross section having a horizontal portion e' and a vertical wall f and disposed upon the horizontal portions and within the vertical walls of these arms C D is a chain or flexible band G pivoted by its ends at g to each end of the/curved arms C D as shown in Fig. 7.

In the thicker portion b of the plate W is a horizontal central slot or groove h in which is arranged to slide two blocks m at each having an open longitudinal central socket t open toward each other, in which is a spiral spring u its tension acting to separate the blocks from each other and the inner one m being arranged to bear by its end against the back of the curved pivoted arms C D at their juncture as shown more particularly in Fig. 7. A horizontal screw H screws through the portion b of the plate and bears against the outer end of the outer block n and serves to force the two blocks forward and as an adj ustable bearing against which the block can rest. Disposed on this plate W aretwo plates J K pivoted together at o each having an arm L projecting forward substantially over the curved pivoted arms C D', each curved on its innerside and having a curved slot M which fits respectively over and engages with pins or pivots d of the plate W below it, the two plates abutting together at their meeting edges and each having an opening N in its inner side, on the edges of which are teeth making an internal gear a2, the two plates overlapping each other through their thicknesses at their rear ends, the internal gear d2 continuing across such opening beyond the central longitudinal line of the two plates. With the plateJ engages a gear P turning on a journal d2 of the plate W and another gear Qturning on another'pivot e2 of the plate W engages with the internal gear a2 of the other plate K', and engaging with this gear Q isa small gear R turning on a lpin f2of the plate W and engaging with this small gear R and the gear P is a segment of a gear S turningon a pin g2 of the plate and which gear has a handle T for operation of the same. Taking hold of the handle T and swinging this segmental gear on its pivot g2 causes the gears Q P' to revolve, which in turn act upon `their respectively pivoted plates J K by their internal gears a2 and cause the plates to move from and to each other as desired swinging on their pivot 'u'.

ln the rear end of the plate W in its upper side are two curved slots or grooves U V curving outward from the segment gear pivot g2 as shown in Fig. 7 in which fits respectively a pin h2 on the under side of the pivoted plates J K so that the two plates when swung on their pivot fu by the swinging of segmental gear S the pins j h2 travel up and along their respective groove U V in the plate W and the curved slots M over the pivot d' of the plates first move forward, and then their arms L' move toward each other as shown in dotted lines in Fig. G and in the backward swing of the segmental gear the arms will be moved from each other and then back to their original position. The smallest gear R. is to turn the gear Q in a reverse direction from' that of the gear P for it to move the arm K in the proper direction. Above these curved plates J K is a plate W which fits over the two pins h2 resting on shoulders thereon, and bearing on the top of the segmental gear pivot or pin g2, so that when this plate W is secured in place by screw nuts m2 on the two pins CZ there will be room enough between it and the block plate W for the pivoted plates J K and gears to freely move.

APivoted at b2 between two upright armsY of the upper plate W is an arm A2 whichi extends forward and to the under side of this arm is attached a horizontal segmental plate, B2 the plate being secured by two screws n2 each of which passes freely down through an opening r2 in the arm A2 screwing into the segment plate B2 their heads resting on shoulders t2 of their respective holes in the arm A2 which limit the height of the plate in relation to its supporting arm, but yet allow of seme movement upward of the segment plate shoulders r1.2 on the screw abutting against the segmental plate. VThe underside of this segment plate B2 is hollowed out and has near its curved edge a narrow rib oredge o2 which extends around the plate substantially in the ,and bearing upon the arm, and holding the block C2 firmly in its position in the arm A2. The block has a vertical central opening a2 in it through which freely passes a screw F2 screwing through the screw nut E2 and extending freely through the lower end of the block 'bears upon the upper side of the segment plate B2. The screw presses the segnient 'plate down for the heads of its screws 'n2 to bear firmly in the seats in the arm A2.

H2 is a narrow at bar having at each end a vertical pin m2 each of which projects up through a separate hole ltin the plate B2 and having across pin through its end to prevent detachment of the bar H2 the pins m3 having free movement through their respective holes, so the bar can be moved back and forth or up and down, and when close upto the segmental plate, it lies freely in a recess J2 in the under side of the plate so that the bar can be disposed in the recess and not project beyond the plate but be iush with the same.

An upward angular portion K2 of the arm A2 has a slot L2 through it sidewise in which is disposed a cross pin M2 of two arms N2 between which the angular portion is disposed and which as one at their other end is secured over and to a pin or journal P2 which is IOO IXO

adapted toturn in bearings in the upright arms Y of the plate W the journal extend-v ing forward at 'one end beyond the bearing arm and bent upward to form a handle Q2 as shown in Fig. l so that swinging the handle up through the cross pin engagement with the arm A2 the arm and segmental plate B2 will be swung up from its positionshown in section lines in Fig. 3 and dtted lines in Fig. 1 into the upright position shown in Fig. l.

R2, S2, are two arms joined together and pivoted as one at t2 between two arms T2 of a rock shaft U2 adapted to rock in a bearing in the block U and from the central portion of the shaft U2 projects a segment gear W2 which is arranged to engage with a small pin ion Y2 on a pin o2 turning in a bearing in the block U one end extending out beyond the block and having on its end a handle A2 for operation of the same. These arms extend transversely each way from the central line of the machine then upward, then toward each other, over and above the plates forr their free-ends B2 which are somewhat en-v larged (when the arms are substantially in an upright position) to be over the pins m2 of the bar H2 in the under side of the segmental plate B2 which position is as shown in Figs. 2 and 4. Swinging the handle A2 up into the position shown in Fig. l by its gear Y2 connection with pin or arbor of they two arms they will be raised a little and then swung back into position shown in Fig. l, which Will move them back out ofl the way of the segmental plate, so that if desired the plate can be swung up from its position shown in Fig. 3 in section and dotted lines Fig. l into position shown in full lines in Fig. l.

The arms R2, S2 have a centrall downward extension piece C2 below their pivot which when the arms are in the position shown in Fig.3 projects 'down through a hole or opening D2 in a projection E2 of the sliding block Uand in the operation of the machine this serves as a guide and a hold to the arms for theirp'roper work as will be described later. As the arms are raised to be swung back, the extension piece moves up and out of its opening leaving the arms free to swing back into the position shown in Fig. 1.

F2 is a rest for the toe of the last and conl sists of a plate hollow or concave on its upper surface having a centrally downwardly lextending arm G2 which fits in avertical being reduced in diameter and fitting y1n a socket to2 in the block U its lower portion 104 ltom of the socket-w4 as shown in Fig. 3 in lnfsection, which serves to hold the rest in its `upper position, its movementsup and `down .being limited by a slot d4 in the arm through which projects a pin. e4 of the block U as shown in Fig. 3.

Allthe parts above described relate to the mechanism for operation on the toe of the each side.

boot or shoe while themechanism at the left relates to operation upon the heel of the boot or shoe.

At the opposite end of the body A is an upright or standard J2 which is arranged to vslide forward and backward or to-and from the toe' end of the machine, in a dove-tail groove f4 in the body. A lug g4 projects down from the bottom of the standard into a longitudinal slot .h4 in the body, which receives a screw K2 adapted. to turn in a bearing m4 and prevented from longitudinal movement by the abutment of its milled head. L2 against the portion M2 of the standard and a shoulder n4 of the screw abutting against the other side of the portion m2 as shown in Fig. 3 in section. The upper end or surface of this standard inclines upward or atan angle of about forty-five degrees toward the last, and is divided into two parts, with-a space or groove between them and in dovetail grooves P2 in the upper ends of these parts is arranged to slide up' and'dowmor to and from the last, abar N2, it 'having on its under side a rib which 'projects freely down into the space or groove between the' two parts of the' standard, its under edge having gear teeth or a rack Q2, with which engages a segment of a gear R2 freely disposedin said groove and securedtol a cross pin or shaft r4 adapted to turn in bearings of thel 'standard uprights,which pin at the front end right,`Fig.,1, the bar N2 is caused to move up theincline in its guideways, and to be moved downward or lowered in swinging the handle' up, andVin both Ways in line with the central longitudinal line of the last or machine. Above this upright J2 is a plate T2 which is connected to-a downwardly extending arm U2- pivoted at t4 to the upper endof the bar N2 which arm U2 at its lower end straddles a block` V2 having a pin'W2projecting from Veach side and extending respectively inL slots a4 in the end of each part. A screw u2 passes freely through a socket@4 in this block screwing intothe bar N2. By means of this screw the plate T2 can' be swung on its pivot to loo have it lie at more or less an angle-in relation to the last, within certain limits it being held firmly in position by the screw u2. The plate T2 is attached to the pivoted arm U2 by a transverse groove joint A4 as showninFig.

3 in cross section, so that the platecan move back and forth along such groove of itself within certain limits being stopped' by a screw pin m4 on the under side of the plate at The front end of the plate hollowed out vertically making two shortarms B4 one each side tothe outer ends of which 'is pivoted at a2 the end of a chain or'iiexible T2 .is concave or band C4 the main portion extending back between the arms B4 in a curved line.

` E4, pivoted together at b and each having a projecting arm or narrow portion cl3 having an inner curved flange e3 which extends out over the flexible band and its supporting arms. The plates D4, E4, are on the same horizontal plane and each has a curved groove f5 disposed over a ring washer g5 on a screw pivot F4 screwing into the plate T3 which fits in the groove and the rear end of each plate has a hole G4 through its thickness, which fits over pins h3 on gears H4, J4, respectively, the two gears being side by side, and engaging with each other and disposed in a recess or depression m3 in the plate T3, the gear J4 engaging with a segmental gear K4 turning on a pivot 'n3 of the plate T3, and extending out from its opposite side in an extension L4 which forms va handle for operating the same. Swinging the segmental gear K4 on its pivot operates to move forward through the gear connection the plates a short distance and then the curved grooves f5 traveling over the pins F4 cause the arms d5 to move toward each other.

M4 is a lever having a hook end T5 pivoted at t3 to a block n4 havinga spring P4 between its arm a5 and the block N4 which acts to force the arm 'L05 outward, its movement being limited by a set screw 'v5 screwing through a socket 'L05 in the arm into the block N4. This block is pivoted to a pin Q4 of an arm R4 of the body in a slot S4 against which p'in Q4 is arranged to bear a pin T4 extending up into a socket U4 in the block N4 and having a spiral spring V4 in the socket bearing against the pin 'l4 to hold it against the pivot Q4. The block N4 has another slot W4in`its end opposite to the hook lever'in which is disposed a cross pin w4 of a lever A5 pivoted at B2y to the arm R4 having a handle C3 for operation of the same. l

As the lever A5 is swung up, by its connection with the hook lever M4, it is swung up and forward so that its hook r3 will be brought over and bear upon the upper on that side of the last, and then pressing firmly down the leverA5 the lever hook r3 will hold firmly down the edge of the upper on the last, but by a yielding pressure. Moving down against its socket pin spring V4 and from the changed position of the block N4 and the lever M4 in its slot in the block as shown in dotted lines in Fig. 8, the lever M4 will be locked in position, and can be easily unlocked and returned to its normal position Fig. 8 by swinging down the handle lever A5. A plate V2 secured by the screws F4 above the plate D4 and E4 and 4 screw nut e3 over the pin n3 holds the plates and other parts in place but so as to leave them free for their operation.

In front of and secured to each flexible band G and C4 is secured a piece g3of suitable soft material such as leather to prevent injury to the upper of the boot or shoe being lasted.

The operation of the machine is substantially as follows: The machine with all its v parts when in its normal position is as shown in Fig. 1 ready to receive the last and upper of the boot or shoe to be lasted. The upper G4 of the boot being placed on the last K the last is placed in the machine by placing its heel socket d over the heel pin H as shownin section in Fig. 3. The toe of the last is then pressed down on the toe rest F3 between the two arms or ends of the flexible band G and curved arms C D', and then the upper G4 at the toe smoothed by hand back or away from the last over and upon the two arms C', D', the segment ribbed plate B2 is then swung over and pressed down irrnly upon the edge of the upper on the arms C', D' at the toe by swinging down its handle Q2; the handle A2 of the arms R2, S2, is thenswung down to the right, which brings the two arms R2 S2 for-` ward and their ends B3, over the pins n3 of the bar H2 in the ribbed plate`l32and continuing the movement of the arm, the two arms R2, S2, are pressed firmly down onl the bar pins n3 which press the bar H2 firmly down against the inner sole H4 on the last and pressing it and the last firmly down into the upper upon its spring yielding seat F3 which stretches and tightens the upper at the toe upon the last, its edges at the toe being held firmly between the ribbed plate B2, and the arms C D at such time; when so held the handle R is raised which through its arms P swings the last pin I-I forward and presses and forces the last toe firmly and strongly against the flexible band G', and thus lirmly holds the toe of the upper between it and the ilexible band, and when so held the ribbed plate B2 is 4swung up out of the way into the position shown in Fig. l, and then the arm T is swung forward orto the left Figs. 2 and 6, which moves forward ortoward the last the two curved arms L of the plates J K', and then toward each other over the toe of the last which firmly wipes and rubs the upper over the inner sole at the toe. The arm S3 is then swung down which through its segmental gear R3moves the block N3 up until its flexible band04 connected thereto closes and bears against the upper at theend of the heel of the last; the arm L4 is then swung for` ward which causes the two plates D4, E4, to move forward over the edges of the upper at the heel, and then their armsdi swung toward each other which rmly wipe and rub the edges of the upper at the heel over and holds them firmly on to the heel of the last. The lever A5 is then swung down which swings the curved arm M4 up and its bearing endr5 over and upon the edge of the upper at a4 as shown in Fig. 2 which presses and holds it irmly upon the last at such place. With the last and the upper secured as described and as is shown in plan view in Fig. 2 the side h3 of the upper is ready to be lasted, which is done by hand or in any suitable lasting machine, and then this side of the boot is secured by tacks and also around the toe and heel. The hooked lever M4 is then swung down and out of the way and the opposite side of the boot lasted like the firstside, and secured by IOO tacks as before, when the last and the upper are removed from the jack, and another last vand upper placed therein and operated upon ing released from its hold by the segmental.

ribbed plate B2.

Thesegmental plate B2 is held firmly down and securely holds the upper over and down upon the arms C', D', by its supporting arm A2 being locked by the cross pin M2 of the lever Q2 then being at the outer end of the slot L2, as shown in Fig. 3, in cross section, for from the relative positions of the slot L2, the pivot b2 of the arm A2 and the lever pin M2 and its pivot P2, the arm A2 is locked and held from swinging up and consequentlythe plate B2 is prevented from movement.

The barN3 carrying the lasting plates, che., is arranged on the inclined gnidewaysy and surface, for it and the parts carried by it when not in use to be moved down out of the way of the last and upper so the operator can have free access to the upper when otherwise handling and operating.
