LASTING .MEOHANISH.

Patented Sept. 12, 1911.

Application filed March 19, 1910. Serial No. 850,434.

To all whom it may concern:

Be it known that I, MAT'IHIAS BRooK, a citizen of the United States, residing at Boston, in the county-of Sulfollcand State of Massachusetts, have invented certain Improvements in Lasting Mechanisms, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on t1 several figures.

' This invention relates to machines for use in forming shoes and particularly to heel lasting mechanism, and has for its object to provide improved heel clamping means. i

One feature of this invention consists in providing improved means for actuating a into the shank of the last.

eelembracing band to cause it to clamp with equal pressure the opposite sides of the heel portions of shoes upon right and left.

lasts which are laterally unsymmetrical.

As iswell known,- many lasts in use at the present time are fuller at the outer side of the heel portion, which corresponds with the outer side of the foot, than they are at the inner side of the heelflportion, particularly. at that part of the last which merges Any adjustment of the heel-bandrclosing mechanism which is arranged to cause it to close farther on one side than on the other for one last is, (if course, wrong for the other one of a pair of lasts. vention, therefore, means is provided for equalizing thepressure of the'band-closing .mechan'i sm'at the two sides of thelast. This means may advantageously be arranged to ermit the band -closing mechanismto ad just the two end portions of the band relativel in accordance with the shape of the last efore the final pressure for clamping faces These inclines cooperatewith abut-' men'ts which cause the slide bars to move. inwardly and force the end jo'rtion's of the band against the sides of the as't assaid bars advance.

Y In accordance with a preferred embodinient of'this inventioh the abutment-s at the in its closing e drawings indicating like parts in the In accordance with the present intwo sides are connected for movement laterally together to position the slide bars automatically as the band closes against the fuller side of the lastl In this positioning movement the portion of the band first contacting with the fuller side of the last pauses movement while the other end portion of t e band is forced up into similar contact with the less full side of the last and thereafter the two end portions of the 'band are caused to clamp the shoe equally at the two sides of the heel. are shown as formed upon the op osite ends of a transverse bar which is gui ed by pins and slots and has free movement transversely of the last.

The two abutments A movable connection is, employed be tween the ends of the band and the adjacent ends of the slide bars in orderto permit the slide bars to continue their advance movement for closing the end portions of the hand against the shoe after the advance movement of the band has been stopped by its engagement with the heel end of the last. A convenient form of movable connection for this purpose includes an angle lever fulcrumed on a slide bar and connected at. one end to the band while its other end is con nected by a s ring to a fixed part of the machine. VVit'i this arrangement the end 'portion of the band is forced inwardly by the turning of the angle lever. Thespring Frireturns the parts to normal position'wher.

the slide bars are retracted.

A novel feature of this mechanism consists inthe rovision of an adjustable angle lever forme to permit the lateral position of f e... end portion of the band with relation t4 the slide bars to be varied for shoes of diflierent sizes.

machine for the groups'of sizes comprised mcns, womens and childrenssh-oes.- 13% the pgesent invention asingle an 1e 'leve, can adjusted to support the proper position for all the difl'etent' widths of shoes. The construction employed prises an angle block, having the usual fularm 0 the lever and lm armfwluchis adjustable lengthwise in said block for conpoint and the outer spring-engagednection with the band. Thisjiidjuptiilile arui which car is herein shown :1 srr threaded ltltl which is secured in znljnslvxl position in tho angle hlocltl 'y nnitub'lr loul; nni's.

' and a transverse'shifting of t fixed portion of the machine head over which the, late 286 is movable and these pins stan in slots formed in the arms of the plate near the lugs 285,- This arrangement of the lugs on the movable plate 286 .permits lateral movement of the lugs together e bars in company and effects an equalization of the inward pressure of the band 'at its two ends. This insures that the band shall clamp the 'upper against the hollow inner side. of the .last with the same force as it is clamped against the relatively full outer side of. the last. This equalization of the pressure at the two sides, in the region of.'tl1e ends of. the heel stiifener, is of great importance in securing good lasting, especially on such crooked and irregular lasts as many of those I wedgefaces of the relatively a now in use.

lhs advised, it is new by this invention to provide, for advancing and closing of the ends of the heel or we band, a mechanism which includes cooperating devices one of ,which, as the slide bars 192, has cam faces to effect closing'of the band ends and one of which, as the plate 286 and its abutments 285, is mounted for self adjustment'transversely of the machine to equalize the band closing pressure at the two sldes of the shoe. M is -to be noted that the equalizer, which isthe plate 286, is independent in this embodiment of the invention from the means which produces the band. 7

In the use of the invention ashoe is properly supported vertically and the last and the heel band are relatively actuated longitudinally and laterally, -.during which movement the heel is thrust against the middle portion of the band and the ends of .the

band are closed snugly against thesides of the shoe. This latter actuation is" eflected by the forward movement of the crossheakl 190 which moves longitudinally toward the right in Fig. 1 the bars 192 which support the levers 194. which in turn support the frontendsof the band. The 006 era- ting vancing members 284 and 285, which are formed respectively on the slide bars 192' and the equalizer 286, swing or turnthe slide bars 192 toward the center ofthemachine and 11love the band supporting levers 194 bodily inwardly toward-the shoe to clamfp the ends of the hand against the sideso the shoe.

' If the shoe isless full on "one side at the end of the handthan on the other side the equalizer 286 moves freely ifrom thele'ss full side to the larger side and thusprovides egual pressure onboth sides." The rear end o theband is supported by thestem 271 in r. the head of the machine"which constitutes theca'rrier upon which all thedescribed parts are movable Of course it is-iimmw terial whether the inclinedfaces 284 are the advance moven'ient' of formed on the bars 192 or on the studs of the part 286 for the effect is't-he same in either case when these parts are relatively moved longitudinally of the shoe.

If it is desired to adjust the band for shoes of different widths this is effected by manipulating the nuts 198, 198 .and screw 280 on the levers 194 in an obvious way. If the band is to be removed the fingers 274 are sprung downwardly against the springs ing screws if the screws have been tightened, and the band can then be ,readily pulled out of its holders. 1 When restored it is pressed close up against the under face of the wipers.
