END-EASTING MECHANISM.

`Specification of Letters Patent. Patented June 10 1919.

Application lecl September 14, 1915. Serial N o. 50,629.V

VTo all whom it may concern: j j Be it known that I, MATTHIAS BROCK, a

citizenl of the United States, residing at Boston, inthe county of Suffolk and State ofr Massachusetts, have invented certain' I mprovements in End-Lasting Mechanisms, of

which thefollowing description, in. connection with the accompanying drawings, isa

been in the direction of approximating the i shape of the last to the shape of the human foot so that the present day last is more nearly like the human foot than lasts ever before used.

This type of last is now in general useand is characterized by unsymmetrica'l shapes .on

the two sides of the heel and kalso on the two sides of the toe. In the case of the heel, generally speaking, thelasts are `characterized by extreme fullness on the outer side o f the heel extending through the shank, the inner fside of the heel extending into the shank being correspondingly cut away. This results in an unsymmetrcal relation of the tread face of the last at the heel end to the counter-portion above it. Y

- Under these conditions, itis highly desirable that the endclamping mea-iis of a lasting mechanism be arranged: to conform to these opposite side faces ofthe-last.' In a form of heel lasting mechanism `in wideuse and shown in United States LettersfPatent No. 1,018,477, granted September 12, 1911,`

upon my prior application, andin connection with which the present invention is shown, the heel seat wipers and heelvband are mounted for bodily transverse swinging adjustment together relative'to a toesupport and about a center located approximately atthe intersection of the longitudinal median lines of the forepart and heel part of the supported last'to position the wipers in symmetrical relation to the tread face of the last at the heel seat. No provision is made, however, forladjustment of the heel clamping band to position the band to conform to the opposed full and cutaway side faces of the heel end of the last since the heel band and wipers move together in symmetrical relation.

An important feature of the present invention consists in an end clamping means,- as shown, an end embracing band, and supports for the ends of said band and a support for the embraced end of the shoe arrangedfer preliminary relative bodily adjustment transversely relative to the shoe support and shoe to position the clamping`v means to conform to, or in symmetrical relation to the opposite full and cut away side faces of the end of the last. When the mechanism of the present invention is applied to a lasting machine of the type Shown and described in the patent previously referred to .and to which the band adjusting mechanism is adapted, bodily adjustment of the end embracing band is effected independently of the bodily transverse swinging ad-l justment of the wipers and band, and enables the band to be positioned in unsymmetrical relation to the tread face of the end of the last when lasts of the described type are to be operated upon.

As shown, means for supporting the ends and the middle rear portion of the end clamping band are carried by a yoke which is manually adjustable transversely of the machine and of a supported last to adapt the band for uniform clamping action against the opposed full land cut away sides of right and left lasts preliminary to the closing of the band.- The described adjustment may also be utilized, when needed, for manually applying speciall or extra pressure against a side of the heel end or shank portion of the upper at or near the end portions of the heel stifi'ener after the, band has been closed in order to shape the heel stiffener and upper to the deep concavity at the inner side of the last. By this means, the shoe materials may be positively forced firmly against the side of this portion of either a right or left last.

A further feature of the invention consists in novel means for obtaining shaping pressure against the shoe upper at vthe coi-ners, or rounded portions located .between the rear end and the sides, of the heel end of the shoe and last. As shown, a stili' spring is arrangedl to exert pressure against each corner of the heel as the lshoe is forced into position to be operated upon. These springs are carried by the yoke previously referred to and in the ordinary adjustment of the yoke are effective substantially to equalize the pressure on the two corners of the heel. In another adjustment of the yoke the springs, which act through the usual heel embracing band and its supporting chain, may be caused to elect' greater pressure on one corner than on the lO ther of a particular shoe. j

A further feature of the invention consists in a novel heel band support.. This is pointed out in the claims.

j plunger is transmitted to the band chain' to tension the band ends forwardly. The Y Figure 1 of the drawings is a plan view of a portion of a heel lastingmechanism in which this invention is embodied.

Fig. 2 is a perspective view of the corner pressure applyingl means and the side pressure applying means. A

Fig. 3 is a perspective. view showing novel band supporting means.

The illustrated mechanism is a heel lasting head and includes a part 2, which may be regarded as a frame, relatively to which a last carrier 3 provided with a heel pin 1 is movable by pinion 6 and band wheel 5 to force a shoe into position to be operated upon. The frame has supporting bearings in which a yoke-shaped member 8 is mounted, said member having guide slots 10 cooperating` with guide studs in the frame to direct movement of the yoke transversely of the frame. The yoke supports the front end portions of bar 12 which operate levers la connected at their inner ends with the ends of a heel band chain 15 and having their outer ends connected jby relief springs 1G to the frame 2. The rear ends of bars 12 are connected through al cross-head 18 with a plunger 20. Forward movement of the bars 12 have wedge or incline faces 13 which coperate with abutments 9 fiXed on the yoke 8 to force the bars, levers and band chain ends inwardly at the same time that the band ends are tensioned forwardly. The band chain is supported at its middle by a stud which enters a hole 7 in the yoke and is4 secured by a binding screw. These parts are,'in'the respects described, substantially like the construction shown in United States Letters Patent No. 1,018,477, granted Sept. 12, 1911 on my prior application.

The yoke S supports two likervsprings 25, each of which' has a long vertical arm, a neck,a short vertical arm and a horizontal attaching portion which is adjustably held by a binding screw V26 in a downwardA eX- tension 27 of the yoke 8. vThese'springs are located to bear against the heel band chain n and apply a stiff pressure at the corners of the heel when the shoe is jacked b ack into the heel band by the hand wheel 5 from the dotted line position shown in Fig.r1. The shape and mounting of the springs 25 gives them capacity for adaptation withoutk substantial change of pressure to wide differences in the sizeof heels. v

` The yoke l8instead of being free to slide transversely of frame 2 asin my prior patent, has threaded engagement'with a screw 30 which canl rotate without advancing in the frame 2 and the screw has a large head by which it can be turned to move the yoke transversely of the machine in the direction of slots 10 bodily to movethe chain and heel band transversely to position to conform to the full outer and cut away Vinner sides of the last, the springs 25 acting under these conditions to equalize pressure on the two corners of an unsymmetrically shaped heel part of a last. lUnder certain conditions the described adjustment means may also be used to apply through springs 25 extra or special pressure to one corner or other of the heel.

The described means for moving the yoke 8` constitutes provision for applying pressure, throughj an abutment` 9, a bar'12,` a lever 14 andan end `portion of they heel band, to the side of a shoe.k This arrangement may be employed asa meansfor v manually applying special or eXtra pressure when needed against the heel end or shank of the upper at and near the end portions of the heel Astiffener to shape the heel stiffener and upper to the deep concavity at the inner side of the last after the bandhas been closed and ordinarily will beV used:

pressure equalizing members 35 which are pivoted upon the chain between' their upper and lower` ends and extend from" the top edge' or the band nearly to its bottom edge. The inner band engaging face of each pressure equalizing member 35 iscontoured vertically to fit the portion of the side face .of the heel part of the last to which it is opposed. The member 35 which `is shown at the left in Fig. 3 is contoured to it the forward ,portionof the heel. The members which are' opposed to'the rear end ofxthe heel are diii'erently contoured to` vtit ,the

smaller degree of vertical curvature which is formed on theend of jthe heel. lThe chain is shown asconstructed, .for the purpose of properly carrying said pressure equalizing members, of pairs of linkmembers 36 between which are interposedthe heads of other link membersk 38, connected thereto by vert-ical pivot pins`39.V `The link members 38 are formed with necks l() which constitute horizontal pivots on which the pressure equalizing members 35are mounted for independent pressure equalizing movement. The described construction serves the purpose of applying .suitably proportioned pressure through the lowervand the` upper portions of the bandtoclamp the upper ma. terials, includingV the heel stiffener, iirmly against the side faces ofthe `last from its bottom edge downwardly for substantially the full width of the heel band, which is usually in excess of the width ofthe heel stiti'ener. A heel band-.made in accordance with this'invention molds the heel stifi'ener and the upper to the lastV throughout the width of the stiifener, whereas he'elwbands have usually irmly engagedonly the por-` tion of the upper at and adjacent to the shoe bottom. v
