LAS Tl NG-MACH IN E.

SPECIFICATION forming part of Letters Patent No. 548,862, dated October 29,1895. Application filed April 22, 1895. Serial No. 546,601. (No model.)

To all whom itmay concern:

Be it known that I, MATTHIAS BROOK, of Boston, county of Sufiolk, State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention has for its object the production of a machine for lasting the toe of a boot or shoe'in such manner that the upper will be drawn about the toe of the last in a smooth and even manner, no matter what the shape of the last, and whether a right or left, means being provided for wiping the upper overthe extreme toe portion of thelast in accordance with'the'shape 0f the latter, the

toe-wiper adapting itself automatically-to the last, whether a right or a left.

In the preparation of boots or shoes for lasting, prior to their treatment by the ma- 'chine to be hereinafter described, the upper is held in place immediately adjacent the toe temporarily by a tack or nail, which is only partially driven in and located at the middle of the bottom of the toe, and means have been provided herein for automatically removing such temporary fastening prior to the action of the end-wiper. The upper is drawn over the sides of the last about the toe'by side-wiper plates, which are so mounted and adjustable as to exert an equal draft upon the Other features of my invention will be'more' fully described hereinafter, and particularly pointed out in the claims.

Figure 1 in side elevation represents a toe lasting machine embodying my invention,

with a shoe in position to be operated upon. Fig. 2 is a top or plan view of the machine shown in Fig. 1, a portion of the bed being omitted. Fig. 3 is avertical longitudinal section taken on the line a: 00, Fig. 2, the shoe being'omitted. Fig. 4. is an under side view of the wiper-plates, their carriers, and the adjusting and actuating devices for the wiperplates. Fig. 4 is a front view of the wiperplates and their carriers; Fig. 5, in elevation and partly broken out, shows the adjusting mechanism. for the toe-support of the last.

Fig. 6 is a' plan view of the controlling-cam to bedescribed; and Fig. 7..is a detail of one of the cam-plates. The bed A, of suitable shape to support the operating parts, has mounted thereon a carriage A, upon the upturned standards A of which ismQunt'e'd a tipping-plate holder B on pivots or tru'nnions a, the said trunnions entering horizontal slots atv in the standards A to permit movement of the plate-holder when adjusted, as will be described.

The tipping-plate holder B has an upwardlyextendedarm b at its outer end provided with a bearing 1), the other end of the tipping-plate holder having a second bearing 19 in 'alignment with the bearing 27', the said bearings receiving therein the journals 0 c of a tipping plate C, the said plate being thus adapted totip at right angles to the axis of movement of the tipping-plate holder B, and preferably .Fig. 3.

V The camD has in its under side a groove (1, (see dotted lines, Fig. 6,) which is'entered by a roller or other stud o tshown only'in Fig. 3) on the upper side of a slide-plate 0 which the journals 0 c are in line withthe central 8c The said tipping plate isadapted to be moved back and forth in a 5 recess 0 in the bars of the tipping plate by partial rotation of the'cam'D.

The slide-plate c is slotted to receive loosely therein a block 0 having a socket formed therein for the ball-like end c of a bell-crank I'oo lever 0 pivoted at c in ears 0 of a bracket l e secured to the under side of the tipping plate by a suitable binder-screw 0, extended through a slot in the bracket, the latter being longitudinally adjustable by means of a rotatable screw 0 in engagement with a thread- 'ed opening in the bracket and rotatable in a lug on the tipping plate, but held from longitudinal movement therein.

The free end of the elbow-lever 0 projects outwardlyin front of the tipping-plate holder 13 and has pivotally mounted thereon at e an end-wiper holder 6', shown in Fig. 3 as socketed to receive therein the cylindrical shank e of the end-wiper 6 consisting, as herein shown, of a curved metallic plate a having secured to its concave face a pad or covering 6 of leather or other suitable material, the shank of the holder being shown in Figs. 1 and 3 as cut away at e to form a shoulder, upon which the pad and its metallic support a rest, the end-wiper being secured to the holder by suitable fastenings.

The holder has thereon at its inner side a cam-surface 6*, held against a roll 20, mounted in ears on the front of the tipping plate 0 by means of an L-shaped spring S, secured to the holder by a suitable screw, as s, and bent around the outer arm of the elbow-lever c and to bear against its hub, as clearly shown in Fig. 3.

Partial rotation of the cam D will, by means of the roll 0 in the groove cl, reciprocate the slide-plate c and rock the elbow-lever c to thereby raise or lower the end-wiper holder 6 and the end-wiper E, mounted thereon. The said end-wiper can rock or swing laterally upon its shank e in the holder to accommodate it to the inclination of the sides of the lasts in a right or a left, as the case may be, the shank being held in place in the holder, as herein shown, by a pin 5, extended through the wall of the holder and entering an annular groove 6 in the shank, permitting rotation of the latter, butpreventing its accidental withdrawal. The cam-surface e guides the end-wiper in its vertical movement, and the springs maintains the cam pressed constantly against the roll 20.

The carriage A has upon its inner end an upturned ear a and a depending foot a longitudinally grooved to receive therein a slidebar a having at its upper end a toe-rest Q of any suitable or usual construction, adapted to support the toe of the last, the said slidebar having secured thereto a slotted block a, held in adjusted position by a set-screw ca to be acted upon by the cam-shaped end a of a rocker-arm at", having at its lower end a stud 01, adapted to enter a hub (L on the foot a the said stud having secured thereto by a suitable set-screw the hub a11 of a handle 0. by which the rocker-arm may be moved, movement of the latter in the direction of the arrow 35, Fig. 5,. permitting the toe-rest e to drop according to the amount of movement of the arm, the slide-bar a being thus moved up or down in the guide portion a as described.

The cam D has two grooves d and d in its upper side, (see Figs. 2, 3, and 6,)the groove 01 being entered by a suitable rollf w on the under side of a slidef, movable in a longitudinal groove or recess 9' (see Fig. 4) in the under side of a slide-bar g, provided with a roll g to enter the cam-groove 01 The slidef is offset at its outerend and extended forwardly to form an abutment f, movable above the end-wiper E and toward and away from the toe of the last, the shape of the cam-groove d being such that the abutment is moved back and away from the path of the end-wiperE as the latter is raised to wipe the upper about the end of the toe, the abutment serving to position the toe of the last when placed in the machine. The slide fhas a lug or projection f extended through a slot 9 in the slide-bar g to bear against the tail of a dog It, pivoted at th to a cap 0*, se-

cured to the tipping plate by suitable bolts 1 10 and by the head of the cam-stud d.

The dog is provided with a pin h to engage an ear h on the under side of an arm k pivoted to the cap at W, the said arm being bent over and downwardly above the abutmentf' and forked to form a claw h, the said claw being adapted to engage a tack or nail partially driven into the middle of the under side of the toe of the last when the latter is placed in position against the abutment, the withdrawal of the abutment, as described, rocking the dog h, by means of the lug or projection f, to thereby lift the bent arm carrying the claw and withdraw the tack or nail from the last. The pin h is so located on the dog that the movement imparted thereto by the movement of the slide fwill act to quickly throw the claw upward and back away from the last.

To take up the recoil of the tack or nail puller and to prevent it flying back partially, I have secured a spring-catch s to the cap (J at one side of the path of the arm h to catch the same when thrown back, as has been described, the spring readily releasing the arm when positively moved into operative position by hand.

The slide-bar g has formed thereon at its outer end and upon its under side a boss 9 in which is secured a pin g, upon which the side-wiper carriers are pivoted at their in- IIO ner adjacent ends, the shape of the said carcarriers to accommodate them to different Widths of toe of a given style or shape of last.

So far as I am aware it is broadly new to adjustably mount the wiper-plates upon their carriers, to thus adapt them for varying conditions in the sizes of the lasts.

Cam-plates n are secured to the carriers is in any suitable manner, herein shown as by a screw and dowel connection at k, the said cam-plates overlapping on the upper side of the slide-bar g, and they are provided with slots 'n', entered by rollers or other suitable studs 0 on a bar 0', longitudinally movable in a transverse slot 0 in the under side of the cap 0*, and connected at o to a casting 0 pivoted at 0 on the cap, the said casting having pivoted thereto an adj Listing-handle 0 provided with a lug to enter between the teeth of a segmental rack 0 to thereby hold the handle and bar 0 in adjusted position.

It will be obvious from an inspection of Fig. 4 that movement of the bar 0' in the transverse groove of the cap-plate will swing the cam-plates n and the attached wiper-plates It about the pivot 9 the direction of movement of the bar 0' to the right or to the left determining the direction in which the carriers will be swung, whether for a right or for a left last. After the carriers have been thus adjusted according to the last the partial rotation of the cam will, through the rollg move the slide-bar g outwardly, thereby moving the wiperplates forward over the upper, the cam-plates n at such time acting to close the wiper-plates m, moving them about their pivotal point.

It will be obvious that if the proper adjust ment of the wiper-plates to the sides of the last has not been made prior to the moving forward and closing of the wiper-plates the adjustment may be provided after such forward and closing movement equally well.

The adjustment of the wiper-plates to the last according as it is a right or left enables the wiper-plates when closed to move over -the upper uniformly and to wipe the same over the last equally throughout the extent of the wiper-plates.

In the wiping of the upper over upon the last it is very desirable to prevent the insole from being pushed or crowded back thereby, and to obviate this I have provided a holddown, shown as an arm a", pivotally mounted V on the pin h and having at its outer end a downturned boss 4' to receive therein a screw r having upon its lower threaded end a holdingdown plate r adapted to bear upon the outer side of the insole and against the upturned flap frequently made in the inner sole, especially in Goodyear shoes. A check-nut r on the screw 0*, between the lower end of the boss and the foot r maintains the latter in adjusted position.

The armr is slotted at r to allow slight longitudinal movement of the arm, and at its under side I have provided a locking-catch 1' to engage a shoulder 0 in the forward end of the cap to normally prevent the lifting of the downhold due to the action of a spring S, mounted upon a suitable stud 0 and having its free end extended beneath the arm r, as shown clearly in Figs. 1 and 2. A pin 'r on the under side of the catch is located in the path of movement of the cam-plates n when they are moved forward to close the wiper-plates to positively move the arm 1ongitudinally to withdraw the locking-catch r from beneath the shoulder 0 the spring S immediately throwing the downhold up and back on its pivot 71 until its upturned end r meets and is stopped by a block or projection 1 on the cap. This withdrawal of the downhold takes place before the complete closure of the wiper-plates.

The construction described makes the withdrawal of the downhold. automatic; but it will be obvious that if desired the pin 0 could be omitted and the downhold unlocked by hand.

The inclination of the tipping plate 0 from front to rear must be adjusted according to the spring of the last, and this is herein accomplished by means of an adjusting-screw 25, extended through a block t, pivoted between ears t on the arm b of the tipping-plate holder, the screw terminating in a ball i held in a socket t on a bent arm A projecting rearwardly and upwardly from the carriage, said arm having a slot A therein entered by a pin 0 extended through the tipping-plate holder and serving as a guide for the latter when being adjusted.

Rotation of the screw t in one or the other direction will rock the tipping-plate holder B on its trunnions a to adjust the inclination of the tipping plate to the spring of the last.

The cam D is operated by means of a suitable hand-lever D in one or the other direction. In Figs. 1 to 4, the parts being in position to last the toe of the boot or shoe, movement of the handle D in the direction of the arrow 75,- Fig. 2, causes the various movements of the parts, as hereinbefore described,

the shapes and relative arrangement of the cam-grooves d, 01 and (1 being clearlyshown in Fig. 6.

To steady the tipping plate C and its attached parts in a yielding manner, I have interposed springs, as S Fig. 1, one at each side, between the tipping plate and its holder B, said plate and holder being'provided, preferably, with ears to form seats for the ends of the springs.
