Be it vknown ythat I, JOHN T. LANCASTER,

a citizen of the United States, residing. at `Beverly, in the county of' Essex and State of Massachusetts, have invented certain Imrprovements in Pulling-Over 'Machinesg'of which` the following description, in connection with the accompanying drawingsgis a specification, like reference y characters on the drawings indicating like parts in thev several figures.

This inventionV relates to machines for v use in the manufacture of shoes and particularly toyupper pulling machines, and is rherein shown as embodied in a machine having means for pulling an upper o ver a last 4at the toe and at opposite sides of the forepart of the last.

In machines of a well known type as .previously constructed the toe lgripperis yield- Y ingly connected with power operating mechanisrnl by which it, Vin company with side grippers, seizes thek upper and pulls it and thenV comes to rest ,holding the upper under tension for inspection and adjustment. When the machine is restarted the ,toel gripper, again in company with and in predetermined time relation to the side grippers,

iis'made' by' the power mechanism to overdraw the upper into position for the wip-` ing and fastening mechanism to ltake control ofthe upper and secure it to thev shoe sole or y innersole. lpendent movement of-*the toe gripper whileL Vthe machine is at rest holding the upperunder tension .but such movement must .be manually eiiected by reaching upto a handle on There is opportunity for Vindelthe front end of the yupdraw lever. That handle must be further elevated to increase theV tension on the upper and lit must vhe pulled down to relax the tension. There is no means to secure the toe vgripper in the position to vwhich it is'manually moved.. All of the power driven 'kupperpulling movements off the toe gripper are yielding'ly effected through spring which must be Weakk enough to insurer against overstraining or tearing the uppers.

The present invention has for an object tojprovide improved means for 'operating grippers and, in one aspect,y 'particularly7 gtQr-QPerating .the gripper .of pa pullnsf specification f Letters-Patent.

invention consists in the combination with a toe gripper of a pulling-over machine and power operating mechanism therefor, of manually controlled means by which the power mechanism may be made to operate the toe gripper as desired. In the embodiment of the invention herein shown,y said means is constructed and arranged toy cause said mechanism to move the toe gripper either in the direction to tension the upper or in the direction to relaX'tension previously applied. Also in the construction shown the power` mechanism may be made to open thetoegripper independently of the normal operation of thehmachine and the grip-per may,` if desired, 'be made by said mechanism to rengage the upper at such feature of this vinvention consists in means to cause power mechanism to` operate the Vother point `as may bey required. Another y toe gripper ofv a pulling-over machine independently' of the side grippers. l The illustrated embodiment of the invention provides means for causing the power vmechanism to move the toe Vgripper either upwardly or downwardly without disturbingjthe side grippers.

i A further featurevof this invention, as

embodied in a pulling-over machine com'-y prising .a toe gripper and upper fastening means and power mechanism connected with the gripper and fasteningl means and having. a normal cycle in which it causes'the gripper to pull the upper andfthehiastening means to fasten it, consists in the provision of manuallycontrolled means which may be l used at the will of the operator to cause the powermechanism to change the'tensionl of the portion ofthe upper held bythe toe gripper;

In still another 'aspect the invention provides novel means Whereb-y the toe `gri-pfper and the side grippers of a pulling-over machine may be moved at the will of the op.- erator to `vary as desired the tension of the upper both longitudinally and transverselyA ofthe last. v.-

These and other `features of the invention including certain details of construction and combinations of parts will now be describedr Wththad 0f ,theaccompanyng drawings, v

which show,7 fill illustrative embodiment of the invention, and will then be pointed out in the claims.

Figure 1 of the drawings is a side eleva-V tion of a pulling-over mach-ine of the type shownl andV fully described in United States Letters Patent No. 1,029,387, granted June 11, V1912, on application ofV Ronald `F. McFeely, and equipped with this invention, and

'Figa 2 is arperspe'ctive view, on a` larger Y scale than Fig. 1, of some of the important parts of the machine provided by this in I pulley. The pinion 2 kdrives continuously a. gear 4, Fig. 1, located at the left hand side of the vertical median plane of the machine and associated with theftoe gripper and the left hand side gripper as will be described. On the right hand side of saidv vertical 1nedian plane is a similar gear and Vconnections therefrom to the, side gripper on that side i of the machine, said connections being duf plicates lof those which will be described for thel'eft hand side of the machine and therefore requiring no explanation. Y

The gear 4 is fast on short shaft carry ing a worm @which engages a worm kgear 8 and thereby drives a vert-ical shaft 10. The vertical shaft carries on its upper end a Worm 12 ,engaging a worm gear 14 by which a shaft 16 extendinglongitudinally of the 7 machine is Vcontinuously rotated in bearings A V formed for itin a bracket'attafched tothe side p f the machine.

. The continuously rotated longitudinal shaft flrhwas on its front end a worm 100, Figs. 1 and 2, engaging a worm gear 102 on Aa short vertical shaft 10.6 which is therefore continnouslydriven. The shaft 106 has on itsY head a beveled gear108 which is located between and adapted to have driving engagement.withl both of tivo beveled gears k110 and 112 which are loose on a transverse shaft 114. The shaft 114 has fastened on it a. pinion 116 which meshes with a larger pinion theV lower end of a lever 120, Figs, 1 yand vLever fulcrumed on .a .plate 122 rigicllvattaehed to the ymachine frame for that :purpose see Fe'- L end-the hub Aof the lever 5.5 ,heegseeriteetahvJamel; ,it baeidrivisa pinion 2V formed on a constantly running `4118 that is engaged by la segmental racl on gagement with a segmental gear 123 that is fastened to the toe gripper andrew lever 124 pivoted on fulcrum rod '146.

The updraw lever 124 supports, near its front end, the toe gripper '125 and at itsrear` 70 end said lever is connected through an adjustably tensione'd'spring 126 with a slide c 127 which carries a roll standing in a track in a' cam block 128 on the cam shaft 55 Y,which is driven at times by a pulley 129 7 belted toa' pulley 131 on the base shaft 1, there being treadle controlled clutch between the pulley 131 and the constantly running pulley carrying pinion 2. Thel side grippers 47 are suspended vkfrom updraw levers 45, fulcrumed onf-rod 146 vand connected .through adjustablv tensioned springs 4 8 with.a slide 49 having a roll standing in a cam` track in the front face of the brake cam50 on shaft A5,5. by which the lmachine is `stopped `automatically with the upper undertension and again at the end ef the cycle of the machine.V This updraw mechanism is'the same as that employed in the machine of said McFeely patent and const itutesv pulling-over means, and power operated mechanism therefor having a normalA cycle of `moveme nt-s and arranged V,to cause lthe grippers yto Vseize the upper and Y come to rest with .the upper under tension for inspection and adjustment, Aas explained in said patent. There is also associated with Y' each gripper atacker which is operated by said power mechanism to fasten the oulled over upper when they machine is res -arted The machinel can be operated to pull 4over shoes precisely as provided for in said Mc@ Feely patent and independently of the new mechanism which is provided by this invention if so desired.Y Y Y i The. new mechanism vconnected, vwith theV toe ygripper updraw lever is Vmanually .controlled by a hand lever 130 fulcrumed on a t stud 132, Fig, 2 and connected 'to the inner @nu of sien n4. t@ Sud@ Sala Shift andere noY pinionllendwise. The pinion has on each ionda ratchet face Vgulapted .to `clutch `with a similar ra-:tchetface on the adjacent end .Y of one or the other of the lcontinuously driven'beveled gears 110, 112 which run in 115 `opposite directions .on the shaft 114 and are free on said shaftexcept when they vclutched to it by the pinion 11.6. The pinion Y is wide enoughsto maint-ain driving engagef ment with pinion 118 in all positions and 120 when it is .clutched to the beveled gear it, will beV turned'in the direction of the arrow on the hub ofV that gear and will notate pinion 118 in the direction` to swing lever Vrearwardly and through segment .Q'Ql' 125 123'will raise the gripper carrying end of tuodraw lever 12,4. The hand lever2130 and .,eonneetene lCerlstitilte the 4illustrated ein g bodment of means under Control of the @essere @aisselle operating through pinion 2 and connections to shaft 114 and updrawlever 124, to in-V crease or decrease the'tension under which the toe gripper holds the upper.` Infpra'ctice the updraw spring 126 may be'adjusted to fa tension which will be only suiiicient to pull up the upper lightly and straighten it on the lastafte`r which the final pull, and it may be the chief upper stretching, will be effected by use of the said means under control of the operator tocause the power mechanism to increase the tension. `The initial pull is a yielding one Athe'extent of 'which'may be measured in units of force. The second pull is unyielding and may be measured in units of length,and it is entirely underv control ofthe operator. The final and most critical portion of the upper stretching operation may-thus be effected in such manner that the operator is afforded the opportunity to observe carefully the condition of the stock and to stop Vthe upper tensioning operation whenlthe condition of the stock andthe position of the tip seam indicate that no further pulling is desirable. To facilitate manual control the clutchY faces on the pinion 116 and the gears 112, 110 are backwardly faced ratchet teeth adapted to slip past each other whenever the resistance to movement of the toe gripper exceeds the force with which the operatorl is pressing the hand lever 130. Y f

A Vcommon practice of many operators is to set the toe gripperv spring-126 to causeV a strong pull to be applied by that gripper longitudinally of the upper to pull theupper forwardly on the last, and duringthe period rof rest the operator reaches up to the toe gripper lever and. manually `relieves the longitudinal tension so that the side grippers can better pull the upper transversely of the last down to the wood between the toe and the instep of the last.- y When a machine is equipped with the illustrated embodiment of this invention the same result can be ac-A complislied much easier and more expeditiously -by swinging the hand lever 130 toward the left, Fig. 2, and causing the power mechanism, through beveled gear 112 and pinion 118, to lower the toe gripper and decrease the longitudinal tension on the upper.

If it is observed, after the final pull on the upper, that successful results in V,the subsequent over-drawing of the' upper into position to be secured to the innersole require that the toe gripper engage the upper at a different distance from the edge,` this gripper may be lowered by power under control of the lever 130 far enough to causeits jaws to be opened by the automatic means characteristic of the illustrative type of ma- `chine and more fully shown and described in United States Letters PatentvNo. 1,030,264, granted on June 18. '1912, upon the application of R. E MeFeely.l Theupper may .then be readjusted in the gripper,` after For causing the toe gripper to maintain-v` the position to which it is moved by the use of the described manual control of the power mechanismy the shaft 114 hasy on its outer end, F 2, two peripheral series of oppositely faced ratchet teeth with which cooperate opposed pawls 140, 142 held to their work by springs 141, 143. The ratchet teeth of both series run outfto a smooth peripheral surface located between them and which, in the central position of the endwise movable shaft and the hand lever130, holds both pawls out of touch with the ratchet teeth.

The use of the present invention on a pulling-over machine v'of the type shown in the said priorpatent is very advantageous, as will 'be understood from the explanation whichhas been given. Further advantages are obtained b-y the use in that machine of Yadditional lmanually controlled means for causing the power mechanism to increase or decrease the tension applied by the side grippers, and manually controlled means for Y this purpose which is adapted. for use in co- .which it can be made to drive one'ory the other of two beveled gears`24, 25'for turning in one direction or the other a beveled gear 32 fast on the lower end fof a short vertical shaft the upper end of which is a screw 35 operating in a block 36 having connection through slide 38 and fork 41, 42 with the rear end of the left hand side gripper lever'45. l i.

The hand lever 30, clutch member 18 and screw 35 constitute manually controlled means by which the power operating mecharuis'm can be made to raise and lower the left hand side gripper. Duplicate means'is provided on the other side of the machine to raise and lower the other side gripper, and the adjacentfends of the hand levers 301for said side grippers are arranged in suoli proxxiniity that they can, if desired, be inanipulated simultaneously. by the same hand of the operator while he en'iplo-ys his other hand iis Y to manipulate the hand'lever 130, whereby the toe and side grippers will all be responsive to simultaneous manual control.

A. brake 145 arranged to engage the shaft 114 serves to hold the shaft adjustedsendwise in either direction with locking pawl 140, or 142 in engagement'with its ratchety .teeth t0 look. the toe'gripper up yor down.l

The brake readily allows the shaft to be moved endwise by lever 130 to central position te cause the tapered ends of the ratchet `teethto force the pawl 1410, or 142, whicherator after each use, and thereby shifting shaft 114V endwise to disengage the'holding pa'wls lfrom their ratchets, an arm 7i is tulcrumed at 73 andV has a connection, not shown, with the brake rod 76 by` which the arm 7&1 is swung upwardly when the brake is released and the machine started for taching the upper. A link 150 extends from arm 7-1 forwardly and upwardly to a swinging cam 152, pivoted at 154, and having a tapering guideway, Fig. 2, for a roll 155 that depends from the hand lever 130. llVhen the cam 159l is swung forwardly one or the other wall ol the guideway will engage the roll and wedge it and `hand lever 1230 to central position. The arm 7 L1 has also a tapering `recessin its upper facethe walls of which are adapted to engage a roll 7:2 on the hand lever 30 and restore said lever and the parte controlled by it to `normal position wlienthe machine is restarted for operating the tackers. A similarly formed and operated arm 7 11 at the opposite side of the machine simultaneously restores the right hand lever 30 to normal position when the machine is restarted. The toe tacker lis shown at 156 and one of the side tackers at 157 in Fig. 1.

A machine of the class described having, in combination, a toe gripper, side grippers, means for effecting relative movement of said grippers and a last to pull an upper both longitudinally and transversely, and Y power operated mechanism` arranged for manual control to permit the longitudinal and transverse tensions of the upper to be changed variably as determined by the operator. l

i4. A machine of the class describedhaving, in combination, a toe gripper for pulling an upper longitudinally, sidey grippers for pulling the upper transversely, constantly driven power operating mechanism, and manual controlling means whereby the operator may cause saidmechanism to operate said grippers to tension ythe upper longitudinally and transversely at 'different respective times.

45. A machine of the class described having, in combination, a toe gripper for' pulling an upper longitudinally, side grippers for pulling the upper transversely, constantly driven power operating mechanism, means for causing said mechanism to effect a relative-movement of the grippers and a last to pull the upper, and meansfor rendering said mechanism effective subsequently to vary alternately the longitudinal and the transverse tensions of the upper.

v 46. A machine of the class described hava last, power driven means for eecting relative movement of sand griippers and the last e to pull the upper; additional power driven means under control of the operator for moving the toe gripper subsequently in a direction to increase the iongitudinaitenslon lof the upper,` and means for locking the' toe gripper to held the upper' under the increased longitl'ldinalI tension.
