` PULLING-OVER MACHINE.

Specification of Letters Patent.

Y.'iimiicaemn mea May a, 1913. serial No. 765,057.

To all whom t may concern Be it known that I, ANeELo PERM, a citizen of the United States, residing at Haverhill, in the county of VEssex and State of Massachusetts, have invented certain Improvenients in Pulling-Over. Machines, of

which the following description, in connection `with the accompanying drawings,is a specification, like reference characters on the drawings indicating like parts in the several figures. Y A Y This invention relates to shoe supporting means for pulling-over -and other upper stretching or shaping machines and is herein shown as embodied in supporting means for a pulling-over machine suchpas is shown in United States Letters Patent No. 1,029,387, granted June 11, 1912 on an application of Ronald F. McFeely.

An object of this invention, among others, is to provide last supporting means which will contribute to the operation performed by these machines of shaping the upper to the last. As herein shown theV last supporting means embodying this invention serves this purpose by engaging the upper on the top of the forepart of a shoe at opposite sides ofthe middle portion of the shoe and Y moving to stretch the portion of upper located between the engaging points. It also serves the upper shaping purpose by engaging the upper on the top of the forepart of a last at or near the middle ofA the last and forcing the upper against the last in the hollow or depression whichis `usually Vfound between the instep and the toe of thelast, particularly if the last has a high toeior prominent toe. In both of these ways this invention assists in overcoming the very common diiiiculty experienced by the upper bridging across this depression from the instep to the toe. This invention may be embodied in mechanism which operates to shape the upper either by pressureor by stretching in the'way above indicated as well as in such mechanism as that herein shown which operates to shape the upper in both of these ways. Y Y

An important feature f of this invention consists in last supporting devices arranged to engage the top fof the forepart of a shoe and to be moved apart in response to last supporting pressure for stretching the stock that is located betweenthermor it may beby movement produced automatically or otherwise after they have contacted with the shoe and before they come into rmlast supporting relation to the work.

Patented nee. a, 1era Another feature of this invention consists i in a last support and means for moving it intoa position opposite to the top of the last and then for moving it into supporting engagement with the work.

These and other features of the invention will appear and be more fully understood in connection with the following description of a preferred embodiment of the invention and will then be pointed out in the claims.

Referring to the accompanying drawings,

Figure 1 is a view, partly in elevation and partly in section, of somuch of a pullingover machine of the type shown in said prior Letters Patent as is necessary for illustrating this invention.

Fig. 2 is a similar View of the parts shown in the lower portion of Fig. 1 showing the changed relation ofthe parts brought about as the operation of the machine progresses.

Fig. 3 is a side elevation of the toe portion of a shoe being pulled over illustrating the manner in which the upper bridges between the instep of the last and a high toe.

The sole-rest 2 and its operating mechanism, the i grippersV 4 and their operating mechanism, and the tackers 5 and their operating mechanism are or may be the same as shown and described in said patent, as may alsobe the general construction of the side clamp arms 6 and the operating mechanism therefor. The rubber covered side clamp lblocks 8 are mountedV to adjust themselves angularly to the requirements of individual shoes, but have no yielding movement outwardly upon the arms 6 such as they usually have heretofore had.

The last supporters are carried by slides 10 which are guided for horizontal movement in blocks 12 secured rigidly to the side clamp arms 6. A spring 13 holds each slide pressed inwardly toward the median line of the machine. Each last supporter 20 is mounted on a carrier 15 which is pi'voted to the slide 10 to swing about a substantially horizontal axis andrests upon the inner end of a lever 16 which is pivoted to the block 12 and can turn about an axis located at 17 but isnormally held with its inner end upraised by means `of a spring 18. An adjustable stopV screw 19 carried by the lever and abutting lar position shown in F ig. 1.V

In the operation of the machine the cycle afl-whichmaybe-1n general as set forth 1n said prior patent, the arms@ are moved toward each" other kfor clamping the upper and.V upholdmg the shoe for the upper securing tacks to be Vinserted after the grippers have given place to-the tackers 5. As the arms 6 move toward each other the adjacent end faces of the carriers l5 engage one another,

the last supporters -20 being at such time located below the shoe and out of touch therewith and each in the` angular position represented in Fig. 1. After such engagement of the carriers 15 with one ane-ther they yield withrelation to the blocks 12 against the resistance of the springs 13. The lower faces of the carriers 15 are inclined as Shown whereby said carriers constitute in effect wedges located between thefront arms of the levers 16 and the last supporters 2O and, therefore, as the carriers yield outwardly' in the blocks 12 they are forced upwardly, moving about their pivotal connections with the slides 10 and therefore carrying the last supportersZO apart as they rise indicated by t ie lower` arrowsin Figa-2'. By

theupward movement of the last supporters against the shoe they press the upper into engagement with the last at the place where the upper is most likely to bric ge between the instep and the toe of the last, particularly if it is a high-toed last. During the described pivotal movement of the last supporters in the direction indicated by the lower arrows in Fig. 2 they rub or stretch the upper toward opposite sides of the last as indicated bv the arrows on the last in Fiff. 2, thus supplementing the action of the grippers which preferably are at this time still pulling upon the upper. ln thesev ways the last supporters cooperate with the grippers to conform the upper to the last and tighten the` upper to a very substantial extent. :When theA lastV supporters are turned into the position shownrin Fig. 2 and the carriers 15 can be moved no farther upwardly, the s upporting levers 1G thereatter yield against Vthe action of their springsjlSlto permitthe side clamp'arms 6 to continue andfcomplete their stroke for bringing the 'clamp blocks 8 into engagement with the shoe at the edge ofthe last bottom. lt is to be .noted that the upper tightening action of the last supporters takes pla'ee prior to the engagement Vpletion of themovement'ofthe arms 6,-s'aid' blocks will be made to cla-mp the" upper firmly to the sides of the last after which the incoming backers-5 willfftr-ip the-,guip-` pers and cause the wipers located on the lower faces of the taekers to lay "the `upper into position to betacked. It will be noted` that the supporting connections for the last. supporters f 20 are so varranged as to afford substantiallyrigid upholding of thev shoe against the impact of the tack drivers.
