PULLlNG-'OVER MACHINE.

Appifiestioi'iiiled January 17, T231.

ings, is a speciiioation, like i'eii'ereiiice chai'-` acteis on the drawings indicating 'like lparte in the several tiguies. Y

rthis invention relates to machines tor use in the manufacture ot boots and shoes tor pulling uppers over lasts, an-dhas more r jiiarticularly in View l.improi'en'ients in the 4upper pulling` means lof such machines,

in pnll-ing-over machines for use on adults slices, for Iexainp'le shoes 'et the welt `or McKay 'ty-pe, 'the opposite side g-rippers i-isualiy comprise, at each side of the shoe, `a pair o'lf lgripper jaws tor grippiiigthe upper substantially ait the location the tip seam and another pair of jaws *for Vgrippingl the upper farther rea-rwarclly at the ball ot the shoe. A machine thus equipped, however, is impractical fior use on shoes ot the smaller sizes, such as A-clhild-rens shoes, since the rea-r pairs ot jaws would operate on the upper so tar trointhe toeot' the shoe as to interfere with the proper pulling `over ot the upper7 and tor the further reason `l at it is ditticnlt -to present such a shoe properly to 'the mach-ine without positioning' portions of the `margin of the upper within the rear pai-rs ot" jaws. lt has therelore been the practice Eto Vprovide different machines "for adults work and for childieiis worit, the adults inaehine -beii'rgl known as a -iive-pince-r inaehine and the ehildi ns -inach'ine as a ytl-nee-pincer ainachine. "hiiethe diiii'erence between ithese niacl'iines involves substantially iliot'l-iin-g more than a substitution ot llitter-ent `side `gripper mechanisn'is, `the time required in making such a chan-ge renders it impractiihy under lordinaryconditions, -to `use the saine machine tor "both adults work and clii'ldrens work. This has imposed la substantial limitation Aupon the use oft the pulliiie'-oi'er machine. particuilafrly in factories mening both adults and childrens shoes where 'theproduction et one or the other ot Serial No. 437,785,

these different 'hinds ot shoes is not suti'iciently large to warrant the ii'iaintenance ot a special machine for that work.

Cine object ot this invention, among others, is to provide a construction whereby the sai-ne `machine may be used on both adults and childrens shoes. To this and other eiids,-a teatiire of the invention consists inn novel construction or gripper mechanism having gripper jaws which may be rendered either operative or inoperative at the will oi the operator. As app-lied to a machine such as above described hiiving iront and rear pairs `ott side gripper jaws, the invention provides a construction whereby the rear pairs ot jaws may be rendered inoperative to pu-ll an upper without affecting the operation oi the front pairs oi"J jaws. ln the construction shown the desired resnlt is eliiected by the provision in 'each side ,gripper mechanism ot a device which is readily inovaiole into or out ot' position to .prevent the rear pair ot jaws 'from gripj'iing the opper. lin using the tive-pincer 'machine on childrens work thev margin of the upper may thus be permitted to ef;- tend within the rear pairs ot' jaws, as most convenient in presenting;l the upper properly to the other gripper jaws of the machine, without itlie undesirable result ot pulling` the upper in locations so tar rearwardly7 from the toe end-ot the shoe. rThe invention thus renders .the tive-pincer pulling-over machine .practically a universal Amachine for `both adnltsand childrens work.

ik 'furthe-r liealture ot the invention consists in .a novel construction and arrangement whereby improved results are secured in the ope-ration oft drawingl the upper inwardiy over the bottoni ot the last. in its illustrative einbodi'n'ient the invention provides a novel organization in which the side grippers in their overdrawing` iiioveinents are turned in such manner as to cause the rear portions oi the gripper jaws to inove tarther inwardly -than the front portions, thus inircasinlt;` the extent ot the puli on portions ot the upper at vthe rear ot the jaws with a twisting' eliect to tigliten the upper both inwardlj7 and forwardly over the shoiilde-r at the jniiction oi" the ball and the shank ot the shoe. in the iinichine shown of the machine on childrens shoes it is found that the upper is drawn into closer conthis result is effected in the use of the machine with the rear pairs of side gripper jaws inoperative, the turning of the side grippers resulting from the fact that the pressure for forcing each side gripper inwardly over the bottomof the shoe is applied at the rear of the line of pull through the front gripper jaws. ln such operation formity to the last than heretofore along the sides of the shoe at the rear of the ball line, in such manner that the Vcustomary use ot hand pincers for pulling the upper inwardly at the sides prior to side lasting or to sewing the upper to the insole is rendered unnecessary.

The above and otherv features of the invention, includingcertain details of construction and-combinations of parts, will now be described with reference to the accompany ing drawings and pointed out in the claims. Y i

For purposes of illustration-the invention is herein shown as embodied in a type of machine the general organization of which is substantially like that shown in United States Letters Patent No. 1,030,522,

granted on June 25, 1912 upon an application of F. McFeely, but it will be' understood that in many of itsnovel aspects the invention is not limited to machines of that particular type. In view of the detailed disclosure in said prior patent of the general organization of the machine, the present description will be confined only to such parts of the structure" as it is necessary to l refer to for an understanding of the invention.

In the drawings:

Fig. 1 is a view'partly in side elevation and partly in section showing the upper pulling means of a machine ofthe illustrative type as equipped with the improvements of this invention and illustrating the operation of the machine in pulling a childs shoe,

Fig. 2 is a side one of the side plates removed,

Fig. 3 is a vertical section on the line 3-3 of Fig. 2, Y

F ig, 4 is a section on the line 4 4 of Fig. 2, and Fig. 5 is a section substantially parallel t0 the plane of the shoe bottom through the grippers and associated parts and illustrating the character of the overdrawing operation.

It will be understood that in machines of the illustrative type the upper of the shoe elevation of a portion of grippers with the cover is pulled over the last against the resist-.

ance of a sole rest 2 by means of a toe gripper and opposite sidegrippers connected respectively to atoe updraw lever t and opposite side updraw levers 6 to which operative movement is .imparted yieldingly throughsprings 8 and 10 by the movement of cam slides 12 and 14 operated respectively bycams 16 and 18 on the cam shaft 20. The toe gripper comprises a gripper casing 22 on which are mounted a pair' of gripper jaws 24, and a gripper bar connected at its upper end to the upd 'aw lever fl and operated in the usual manner first to close the jaws on the upper and then to move the jaws and the casing to pull the upper. The side grippers in the illustrative type Aof machine present at each side of the shoe a front and a rear pair of gripper jaws 28 arranged respectively to engagey the upper of an adults shoe substantially at the location of the tip seam and farther rearwardly at the side of the forepart, the'two pairs of jaws at each side being mounted respectively on separate gripper casings 30 and 32 slidingly mounted on a single gripper bar 34 which is connected at its upper end to the corresponding side updraw lever 6. The details of the side gripper mechanisms will be Vmore particularly described hereinafter, but it will be understood that, similarly to the operation of the toe gripper, the side gripper jaws at each side of the slice are closed by the movement ofV their gripper bar 34 which acts subsequently to move the jaws and the casings 80 and 32 to pull the upper. After the upper; has been pulled the machine comes automatically to rest .to permit inspection of the Work and any necessary adjustment.

Upon a subsequent starting of the Inachine the overdrawing and upper fastening operations are performed, the grippers being forced inwardly over the shoe bottom by overdraw springs 36 and by the assistance also of a toetacker arm 38 and opposite side tacker arms 40 which are forced inwardly against the respective grippers into position for driving the upper' fastening tacks, .these arms being` provided also with the usual oiverlaying devices for wiping the upper inwardly and -holding it at the tacking points. In their inward movements the several tacker arms press against tripping members 42 on the diiierent grip-- pers, and when the pressure becomes great enough these members are operated to break the connections between the gripper bars and the gripper jaws and permit the jaws to open and release the upper. Following the tacking operation the parts of the machine return to their starting positions.

By reference to Figs. 2 and 3 it will be seen that, similarly to the construction shown in said prior patent, each pair of side gripper jaws comprises a iixedjaw and a pivoted jaw on the associated gripper casing, and that in each of the casings 30 and 32 there is llt) retrasos' a closing slide 444 provided with a roll 46 to engage the pivoted jaw and close it on, the upper stock through upward movement of the closing slide relatively Vto its casing. Movable laterally in each of the closing slides 44 is a slide block `48, these blocks receiving the opposite ends of an equalizer bar 50 which is pivoted on a central block 52. The gripper bar 34, which extends downwardly inte both'casings 30 and 3Q, carries a pivoted latch 54 which, in the starting position of the machine, is arranged to hook under the block 52, as shown in F ig. 3, the latch being held in operating position by means of a spring plunger 56. lhen the parts are in this position lugs 5S on the gripper casings are in engagement with portions ot the frame of the ymachine and springs GO in the gripper bar are under compression betwen the bar and pins 6201i the gripper casings. The closing slides 44 are thus relieved of upward pressure and are positioned suiiiciently low in the casings to per. mit the aws to stand in open position. When the gripper bar 34 is moved upwardly upon the starting ot the machine, the springs GO expand while holding the gripper casings in their lowermost position, and the bar thus acts through the latch 54 to raise the block 52 and through Vthe equalizer bar 50 and the closing slides to close the pivoted jaws on the upper stoel; with substantial equalization oi pressure of the two pairs of jaws on the stock through the action of the equalizer bar. As soon as the jaws have been closed with suiiicient pressure the gripper casings begin to move ,upwardly with thejgripper bar to cause the jaws to pull the upper, the equalizer bar andv the relatively movable closing slides and casings permitting relative movement of the dili'erent pairs ci' gripper jaws in proportion to differences in resistance of the different portions of the upper. It will be noted b-y reference to vFig.l 3 that the tripping members 42 on the opposite side grippers are pivoted on the blocks 52 with their lower ends in position, to engage the lower hooked ends oi the latches 54, and through pressure of the side tac-lier arms in the overdrawing movement of the grippers the members 42 are operated to push the latches-l from under the blocks 52, thus releasing the blocks and breaking the connection between the gripper bars and the closing slides 44, which permits the gripper jaws to open and release the upper.

F or purposes of this invention the rear gripper casing 32 of each side gripper mechanism has doveta-iled therein, at the back of the outer cover plate G4, ay locking member 66 which may be moved from the full line position shown in Fig. 2 into the dotted line position in which it projects within the opening in the rear closing slide 44 in which the block 48 ismounted, this block being cut away or recessed on its outer side (Figs. 2 and 4) to admit the locking member.l lVhen the locking member is thus in its inner position it serves as a stop to prevent such upward movement of the rear slide 44 relatively to the casing B2 as to closel the rear gripper aws. When the machine is operated under these conditions the rear pair oit jaws at each side will not be closed, notwithstanding the `fact that the rear jaws and their casing 32 may be moved bodily upward by the act-ion of the. equalizer bar 50 which acts-as usual to close and operate the 'lront pair oi' jaws when vthe gripper bar is moved upwardly. ln using the machine on a childs shoe, for example, the margin of the upper may be positioned within bot-h the front and rear pairs of side gripper jaws, as convenient in presenting the shoe to the machine, but the rear pair olf jaws at each side will be inoperative to grip and pull the upper and the upper will be pulled only by the 'front pairs o't side gripper jaws. the manipulation of the locking slides 6G the machine may be changed very quickly for operation either on childrens shoes or on adults shoes. To assist inmoving the slides GG in or out, each slide in the construction shown is provided with a groove GS to receive the edge of a screw driver or other suit-able tool. vTo insure that the slide will remain in either its inner or its outer position, a spring plunger 70 is provided ior engagement with suitable recesses in the back tace of the slide. The construction shown is thus simple and convenient and out of the way ot other parts of the machine, but it will be understood that the invention is not limited to the details ot' the mechanism herein illustrated for locking or releasing the closing slide.

It will be understood that in machines ot the illustrative type each side gripper mechanism is so mounted on the updraw lever and in theV guiding i1 ame that it may turn about an axis extending transversely ol' the plane of the shoe bottom. lVhen both pairs of gripper jaws are in engagement with the upper there is no substantial turning movement of the gripper one way or the other in the overdrawing operation by reason vofthe fact that. the upper opposes substantially the same resistance to the inward movement oiE both pairs of gripper jaw". Vhen the rear pair ot side gripper jaws, however, is rendered inoperativeas above described to adapt the machine, 'tor example, i'or operation on childrens shoes, the work offers no resistance to the inward movement of the rear pair otl side gripper a vs in the overdrawing and overlaying operation aside from the resistance to the inward movement of the side gripper as a whole by reason of the engagement of the :front pair of jaws with the upper. It will also be evident that the inward pressure of the side tacler arm against the tripping member 42, which as above explained assists in forcing the gripper inwardly o-ver the shoe bottom, is at the rear ofthe line of pull throughtlic front pair of jaws. The result is that the pressure against the member 42 serves to turn the gripper about its connection with the updraw lever, swinging the rear portion of the front pair of jaws Afarther inwardly than the front portion with a twisting effect on the upper stock in such direction as to tighten portions of the upper at the rear of the jaws inwardlyA and forwardly over the shoulder at the junction of thereforepart and the shank of the shoe. rlhis action is assisted, moreover, by the operation of the side overdraw springs 36 which are in engagement respectively with opposite ends of a plate 72 that extendsv across the gripper, since the rear springencounters less resistance than the spring at the front end of the plate. The result is that on a childs shoe the upper is pulled more-perfectly in conformity to the contour of the last than heretofore, and it is found that when shoes have t-hus been operated upon by the machine there isno necessity as heretofore for pulling the upper inwardly at the rear of the ball of the shoe preparatory to side lasting or to sewing the upper to the insole.

In using theV machine with the rearpairs of side gripper jaws inoperat'ive it is desirable to prevent the driving of the tacks which, in operating on adults slices, are driven in position to hold the portions of the upper which Vare operatedupon by the rear pairs of jaws. This may be done by the use of the tack controlling mechanism with which machines of the illustrative type are commonly provided, as shown in United States Letters Patent No. 1,135,957 granted on April 13, 1915 upon an application of R. F. ,McFeely Having described the invention, what 'I claim as new and desire Vto securek by Letters Patent of the United States is 1.
