Ton/ll whom it may concern: \7 t Be it known that LMATTHIAS BROOK, acitizen ofthe United States, residing at Boston,

in the county of Suffolk and Commonwealth of Massachusetts, haveinvented certainImprovements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specifica tion, like reference characters on the drawingsindicating like'parts in the several fignres. v r

' This invention relates to lasting-machines of the type known as the McKay and Cope-' land lasting-machine, and particularly to the mechanism em loyed in that machinefor lasting the sides. the shoe. .The side-lasting mechanism of said machinecornprises a cally-movable cross-head.

As the machine has been heretofore conplurality of girth-fingers located upon each side of the machine and carried by horizontally-movable slides mounted upona vertistructed girth-straps were attached at one end to the girth-fingers on one sideof the ma.- chine andextended across the median line of them under tension.

In theoperation of the machine the crosshead supporting the finger-carrying slides was first raised, whereby the girth-straps attached to each set of girth-fingers were drawn upwardly across-themedian line of the ma chineland' along the sides of the shoe, the

5 springs to which thestraps were connected yielding to allow this-movement, and the upper of the shoe was thereby stretchedsimultan'eouslyupon its two sides upwardly along the sides ofthe last. After'the cross-head had been raised to a position 'wherethe girth fingers were a short distance above the bottom of the last the fin er-carrying slides were moved horizontally or carrying the girth- Specification of Letters Patent.

fingers toward the median line of the machine and folding the upper over the edge of the ing-to 'lower the girth-fingers to the level of the bottom of the last asthey were moved inwardly, whereby the marginal portion ofthe upper was laid over on the bottom of the last in positionto be secured by tacks to the inner sole. This horizontal movement ofthe fin er-carrying slides was eflected by means of evers, which were each connected at one end with a slide and at the other end were acted'upon by a cam-plate, which was auto matically operated to rock the lever for forc-.

In the use of the machine above referred to certain difficulties have been encountered in lasting shoeson what are known as crooked lasts. Theselasts havea large amount of 5 swing or projection on the outer side so' last, the crosshead simultaneously descendthat a greater portion of the width of the last bottom is'on one side than on the other of the,

median line, extending from the center of the 'toe of' the last to .thecenter of the heel. Of course this excess of width is on the right side ofa right last and on the left side of a left last, so that the right and left lasts, are of very different shape; The lasting devices cannot be 'adjusted'to conform tothe shape of either a right or left last, because any adjustment 're quired for one last is the'reverseof that regquire'd for the other.v When the girth-fingers are moved inwardly for overlaying the upper on the inner sole in the operation of lasting a shoe-on a crooked last, the girth-straps on one side of the machine meet the edge of the wide side of the last beforethe, girth-straps on the other sidefreach the edge of the narrow side of thellast. one of the results of this is that the last, especially the toe end of it, is displaced laterally ,in the machine and ing mechanism. Another result-is that inasmuch as the last-supporting means resists the lateral displacement of the last and does not permit the last to be moved freely, the girthfingers on the wide ,side begin to move over the last before those on the narrow-side do, and so the girth-straps are carried over the bottom of the last a longer distance than they .put out of operative relation to the toe-lastshould be on the wide side ofthe last and a sirable to have the fingers moved inwardly less distance than they should be on the narj over the edge of the last ust far enough to row side of the last, and frequently the upper is not drawn over the narrow side of the last far enough to enable the workman to secure it properly on that side while it is drawn over much farther than it should be on the wide side. To overcome this ditliculty and enable the machine to last shoes properly on crooked lasts is one of the objects of the present invention, and to this end I have provided the machine with means for causing the side-lasting mechanisms to adapt themselves automatically to the. shape of the last presented to the machine and to stretch the upper and layit over on the bottom of the last equally on both sides irrespective of whether the last is a right or a left last.

The shape of the edge of the last is fre quently such that the fingers bearing the girth-straps, which extend under the fore part of the last, meet the edge of the last before the fingers bearing the girth-straps, which extend under the shank of the last. In order to permit the girth-straps at the fore part and at the shank to come into bearing with the edge of the last equally, the machine is provided with one set of levers for actuating the girthfingers carrying the girth-straps for the fore art of the last and with another set of levers or actuating the girth-fingers carrying the girth-straps for the shank of the last and also with independently-movable cam-plates for actuating the levers of the shank-lasting devices and the levers of the fore part-lasting devices. The machine is also provided with means for automatically returning the sidelasting mechanisms to their normal lateral positions, in which the girth-fingers on the two sides are each spaced an e ual distance from the median line of the mac line.

In lasting-machines as heretofore constructed the girth-fingers have been so connected to their carryingslides that they could have no independent horizontal movement thereon. In practice the machine is used with one adjustment for lasting three sizes of shoes-as, for instance, 4s, 5s, and 6sand a different adjustment is made for the next three sizes. If the girth-fingers were properly adjusted for operating on a size-4 last and a size-6 last were put into the machine, they would sometimes strike the side of the last as the cross-head rose, and in doing this they would bruise or mar the upper. This was particularly a t to occur if the large last was also unusua wide or unusuall crooked." Another di 'culty found was t at inasmuch as the finger-carrying slides were positively actuated inwardly said girth-fingers were unyieldingly moved over the bottom of the last always to the same innermost position, thus traveling a uniform distance at each operation of the machine irrespective of the size of the last. It is dei l i 1 1 j 1 l 1 fold the marginal edge portion of the upper over the edge of the last as the cross-head is lowered without drawing the girth-straps across the edge of the last. If the machine is adjusted to give this extent of movement to the girth-fingers when a size-i last is in position, it will obviously move the lingers a much greater distance inwardly from the edge of the last when a.wider last, such as a size 6, is in position.

In moving the girth-fingers farther than is necessary for merely folding over the marginal edge of the upper the girth-straps are dragged across the upper at the angle where it is turned over the edge of the last, and in so doing tend to indent the upper and leave marks on it. Also if the inner sole is thin the girth-straps tend to crowd its edges inwardly from the edge of the last and cause it to spring up away from the last in the middle. T o overcome these difiiculties, the girth-tingers of the present invention are so connected to the slides which carry them that they may move horizontally thereon, and yielding means is provided for holding the fingers normally in their innermost posit ions. This arrangement ermits the lingers to move away from the ast without injuring the upper if they contact with the side of the last in rising. This arrangement also permits the fingers which are properly adjusted for overlaying the upper on a small last to yield backwardly in; their carriers when being moved over a larger last and so travel over the bottom of the last only approximately the same distance from its edges as they travel over the smaller last, thus avoiding any tendency of the girth-straps to mark the upper or to crowd the inner sole back from the edge of the last. This movable connection between the girth-fingers and the carrying-slides constitutes an'important feature ol this invention.

In the embodiment of the invention herein shown each girth-strap is attached at one end to one girth-finger and passes through guides on an opposing girth-finger and its carryingslide in such a manner as to hold the two girthfingers yieldingly at the innermost limit of their movement on their carryingslides. Of course. other means might be employed, if desired, for holding the girth-lingers in their innermost positions and permitting them to yield when unusual resistance is encountered.

When the rock-shaft 12 is rcturned'to its normal position for allowing'the main shaft to stop, the sprin 22 'reversely turns the shaft 19 and applies the brake to bring the rest. A pinion 28 is fast on the front or left-hand end of the main shaft 3- (viewing Fi s. 1 and 2) and meshes with a toothed whee 29, fast on a shaft 30, which is journaled at one end in an extension 20* of one of theposts 20 before referred to and at its other end in a suitable support. (Not shown.) The, shaft also has mounted upon it by means hereinafter .described 31, (see Figs. 2 and 3,) which meshes with a pinion and drives a large toothed cam-wheel 32,-

fast on a shaft 33, which is journaled in stands 34* 342,, in the base, as shown in Fig; 1

' The cam-wheel 32 has formed on its left- Fig. 4) a spiral camgroove 34 (Shown in F ig. 3;) A centralcolumn 37 is erected on 'the'base 1., partially inclosing the cam-wheel 32, as most clearly. shown in Fig. l. I The column carries at its top a table 38,and within the column is arranged in suitablegujdes a vertically-sliding cross-head 39", which'has depending from it an adjustable actuatingrod 40, forked at itslower end to straddle and be guided by the shaft 33," above montioned.i (See Figs. 1 and 4.) p

The actuatingrod 40 is provided on oneside with aroller41, 7.

which travels in' the 'spiral-cam-groove 34 in the cam-wheel 32, above described, whereby therotatioh of said cam-wheel in one direc- 39 to be raised,

and rotation in the opposite direction causes yitto be lowered. Th'e'cross-head 39carries upon its upper endvat either side two slides and 9 2.

The'slides 90 support the lasting devices which operate at the'fore partof the last, and

to this end they are grooved transversely, as

shown most clearly in Fig; '6, to receive loosely blocks 91,-lwhich aresocketed for the of finger-carriers 94, which support girth fingers 98. The stems of the'finger-carriers may be clamped in the blocks 91 by means ofset-sereWs 95 tohold the girth-fingersi'in any desired position, or v said stems may be left free to turn in their sockets, so that. the girth-fingers may autoanativnll'y adjust themselves to the contour of the :u'ljacent edge of the last to which they are pr( sented. The girth-lingers are arranged in pairs opposite each. other, and to &

the inner free end of each finger is attached one end of-a girth-strap 100, which extends from the finger across to the opposite side of the machine and through a guide-loop 102 on the opposite girth-finger. The outer free end of each girth-strap is secured to a spring 110, which holdsthe girth-strap always under tension.

' nected to springs 119 for holding them under tension.

' The last having the upper, toe-'stifiener, heel-stiffener, and inner sole thereon is supported upon an adjustable heel-post 120 and a toe-pad 122 in position immediately above the girth-straps and is held against upward movement by a downhold 128., The downhold is supported upon a cap-plate of the toe-lasting mechanism, being connected thereto bya pin-and-slot connection at 130, which permits the downhold to have a pivotal and also a longitudinal movement. The downhold has a lug or stud 128 on one side, which is adapted to engage under a fixed projection 129 for fastening the downhold in its operative position after it has been turned down upon the shoe and then moved rearwardly. Thespring 132 retains the downhold in position with the lug 128 engaged under the projection 129, as shown in dotted lines in Fig. 1.

The toe-lasting mechanism, which will preferably be the same as that shown in United States Letters Patent N5. 601,933, dated April 5, 1898, and therefore will not be described herein, is mounted for longitudinal adjustment upon the table 38 and comprises, among other parts, an' abutment 100, against which t e toe of thelast may be positioned. ,The table 38 also supports a heellasting mechanism, which will preferably be the same as that shown in my pending application, Serial No. 686,319, filed July 19,1898, said mechanism comprising among its parts a heel-band 157. The heel-lasting mechanism is movable longitudinally of the table by means of a hand-wheel 143 for clamping the last between theheel-band 157 and the abutment 100*.

When the cross-head 39 is raised by the ac-, tuating-r'od 40 and the spiral groove 34 in the cam-wheel 32, the slides. and finger-carriers mounted on said cross-head will be likewise raised to cause the girth-fingers to draw the girth-straps tightly about the body of the last to stretch and conform the upper to the shape of the last. The extent of the upward movement imparted to the cross-head is sufficient to carry the girth-fingers to a point somewhat above the level of the bottom of the last.

To prevent accident, which might occur if the main shaft 3 were not stopped promptly when the side-lasting devices had reached the limit of their movement, the pinion 31, before mentioned, is mounted upon a sleeve 31, loosely engaged about the shaft 30, (see Figs. 2 and 3,) and clutched to the latter bya suitable clutch, shown as comprising a disk 61, fast on theend of said sleeve 31 and adapted to be engaged by a coiiperating clutch member 62, which is splined upon the shaft 30. The clutch member 62 is grooved circumferentially to receive the end of a lever 63, (see Fig. 2,) which is fulcrumed at 64 and provided at its opposite end with a stud running in contact with the face of the camdisk 65, fast on the shaft 33. (See Fig. 1.) When the shaft 33 has rotated its proper distance, if the main shaft is not stopped by the workman, the cam will disengage the clutch members 61 and 62 and stop the rotation of the shaft 33 and therefore sto the rotation of the cam-wheel 32, by which t 1e side-lasting devices are actuated.

A slide-plate 140 is mounted within the cross-head 39 and is arranged to be reciprocated vertically in guideways 142 therein. The slide-plate supports a cam-plate, or, in the present instance, a plurality of camplates 150 and 170, (see Figs. 3 and 5,) from which the girth-fingers o crating at the fore part and at the shank of the last, respectively, derive their horizontal movement, and said slide-plate is provided with a depending adjustable actuating-rod 144, which is forked at its lower end to straddle and be guided by the shaft 33, as shown in Fig. 3. The ac tuating-rod is provided with arollcr-stud 146, standing in the spiral groove 36 in the camwheel 32, before described, so that said camwhcel gives to said slide-plate a risingandfalling movement. The cam- grooves 34 and 36 are so shaped that the slide-plate and the cross-head are moved together during the rise of the cross-head, and thereafter the slide-plate has a further upward movement, while the cross-head is slightly lowered by the portion 34 of the cam-groove 34 (see Fig. 4,) for causing the girth-fingers to move the girth-straps for folding the upper over the edge of the last and laying it down upon the inner sole.

' The cam-plate 150 is pivotally connected byastud 152 to the upper end 154 of the slideplate 140, above described, and is provided at either side near its lower end'with guiding means, (shown as oppositely-inclined slots- 1 56,) which receive studs 158 on the lower ends oflevers 160. (See dotted lines in Fig. 5.) The levers 160 are fulcrumed on stud 162, projecting from the cross-head in; the upper'en'd of the cross-head and are connected to the transversely-movable slides ,nected'to the/stud. 1.52 at the upper end 154 or" the slide-plate 140a1'1d 1s provided at elther sidenear its .lower end with guiding 1 76,)whi'ch-receive studs 1 78 on the lower end of levers-L80.

ates the difficulties heretofore experienc'dfin lasting shoes on crooked lasts with machines;

of this class in which the girth-fingers. were positively moved together through the same distance and the girth-fingers or=g1rth-straps withxthe edge of the last which first contacted tended to force the last laterally as they moved over itYuntil such time as the fingers or straps on the opposite side came into bearof the last unequal distances, the fingers operating at the wide side of the last moving over it a much greater distance than the fingers operating on the narrow side-of the last, and frequently the girth-fingers didnot lay the upper over upon the narrow side of the last far enough to permit it to be secured to a girth-fingers which operate uponthe'shank of the last, are actuated by the independentlyrnovable cam-plate 170 and levers 180, as. it 18 found that it is desirable to permit the fingers actingon the shank to move relatively to those acting on the fore part of the shoe,

so as to enable said twosets of fingers to adapt themselves to the contour of the edge of'the last. If desired; each of the fingers acting at the sides of the shoe might be mounted on an independent slide and actuated by an independent lever, so that said fingers might be permitted to move relatively when they met the edge of the last, and such a construction would. be within the scope of the present invention.

' It will be understood thatthe cross-head is raised and the irth-fingers moved inwardly for lasting the shoe by a rotation of the main shaft inone direction'and that the girth-fingers are moved outwardly and the cross-head is lowered, thus restoring the parts to their original positions by a rotation of the main shaft in the reverse direction.

The cross-head 39 is provided on its lower end at eachsideof the machine with lugs 190 in position to engage the movable cam-plates 150and 170 when they are lowered into their 4 starting positions. These lugs serve to shift the earn-plates laterally and restore them to their central normal position, in which position the girth-fingers upon tthe o posite sides of the machine are positioned t e same distance from the median line of the machine.

The girth-fingers 98, operating at the forepart of the last, are mounted in ,guideways formed by walls 191 on the finger-carriers, and said fingers are-connected to the fingercarriers by means of a pin-and-slot connection comprising pins 192 and slots 194. This connection ermits the girth-fingers to have a horizonta movement in their uideways during the operation of the mac ine, this movement being independent'of the movement of -the slides 90. For the urpose of holding the fingers normally in t eir innermost position, as shown in Fig. 6, each girthstrap extends througha guide-loo 102 on the finger opposite to the one to w iich it is attached, and after passin through said uide-loop the strap passes ownwardly and inwardly over a roller 104, mounted on the finger-carrier, and from thence upwardly over other rollers 106 and 108 on its way to the tension-spring 110, as clearly shown in Fig. 6. By this arrangement the girth-strap acts to hold the two opposite girth-fin ers yieldingly in their innermost positions w iile permitting said fingers to be moved outwardly. This construction is of advantage in that if the girth-fingers on either side of p the shoe meet the side of the shoe when the cross-head is being raised they can yield outwardly until they have passed over the side of the shoe, and this is done without bruising or marring the upper, whereas if the fingers were rigidly connected to the finger- -carriers they. would scrape against the upper in such a case and injure it. Another advantage is that inasmuch as the fingers are not positively forced inwardly over the bottom of the last they will stop after having moved far enough to fold the upper over the inner sole and will not draw the girth-straps across the angular edge of the last and indent the upper-lor force the inner sole away from the edge of the last.

In using the machine the shoe is put into place whileithe cross-head is in its lowermost position and the girth-fingers are spread apart, the heel-band being open. The heellasting mechanism is next advanced to bring the heel-band into engagement with the heel end of the last and clampthe last between the heel-band and the usual abutment on the toe-lasting mechanism. The machine is then started by depressing the foot-piece 13 of the treadle-arm 13 of the rock-shaft 12 to put the friction-disk 6 into engagement with the pulley 4 and cause the main shaft to be started and the cam-wheel 32 to be rotated in the direction of the arrow thereon in Fig. 4. This .results in raising the cross-head by means of the cam-groove 34, acting on the actuating-rod 40. The rise of the cross-head continues until the portion 34 of the camgroove begins to act on the stud of the actuating-rod, after which the cross-head is slightly lowered. The slide-plate 140 moves up- Wardly in unison with the cross-head while the latter is rising and continues to rise during the short downward movement of the cross-head; Y During this independent upward movement of the slide-plate and the cam-plates carried thereby the girth-fingers are moved inwardly to cause the girth-straps to fold the upper over the edge of the last. The combined inward and downward movement of the girth-fingers causes the girthstraps to lay the marginal portion of the upper over upon the inner sole. If the workman fails to release the treadle-arm at the right time, the cam 65 disengages the clutch members 61 62 and stops the machine at the time the lasting devices reach the limit of their movement. If the last is crooked, the girth-straps in moving inwardly meet the edge of the last sooner' on one side than on theo'ther, andthe cam-plates swing ,on their pivo't,allowin the levers 160 and 180 .actu-.

'a'ting the girt -st ra s which first meet the. last to pause, while t ose actuating the'-girth-' ,straps at the opposite side of the last concome into-bearing with the edge of t tinue to move untilv those girth-stra s also hieflast, after which the levers on both sides are lnovedtogether to cause the girth-straps to act uniformly on the two sides of the shoe.

Ifqthecontour of the edge of the-last is such that the girth-straps for lasting the fore part meet the last before those for lasting the shank, or vice versa, the girth-straps first meeting the edge of the last are stop ed and 'ait until the other girth-stra s on t e same side come into bearing with t e edge of the last. This causes the cam-plates 150'and 170. to move relatively until the two sets of girth-straps come into bearing equally with the edge of the. last, and thereafter said camplates move together, so that the girth-straps ot the fore part and -of.the shank actun'iheel and toe shaft isturned in the reverse direction to that in which it was first turned. .This causes the cam-wheel 32 to'be turned backwardlyorin' thcxopposite direction to that "indicated by the arrow in Fig. 4, whereby the slide-plate and the cam- plates 150 and 170 are, first drawn downwardly for moving the lowered to itsinitial positionj' m-plates en'- said camplates totheir initial central positions with the lasting devices on each side spaced the same distance from thejmediany line of the machine, so that ';they areflprep'ared' to actnext-either on a right shoe or a left shoe.

If' the girth-fingers meet the side of the/last when-the cross-headis being raised or low cred, they will yield outwardly without'injuring the uppenof the shoe; If a shoe-is being lasted which is larger or wider than the size of shoes for which the machine has been adjusted, the girth-fingers will-yieldbackwardly in their carrying-slidesv after having moved over the last only approximately the 1 stm'le rlistance as they would have moved over .thesinaller last 'for which they were adjusted.
