T all whom it may concern Be it known that I, RONALD F. MGFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Pulling-Over Machines, of Which the following description, in connec tion with the accompanying drawings, is a s ecification, like reference characters on t e drawings indicating like parts in the several figures. I

This invention relates tomachines for use in the manufacture of shoes and is herein shown fonthe purpose of explanation as enibodied in a pulling-over machine of the type of that shown in United States Letters Pat out No. 1,029,387 granted on my'application June 11, 1912.

One object of this invention is to provide improved operating means for tools for working on shoes and a feature of the invention consists in the combination with such a tool of operating means including a manually controlled spring for effecting initial operative movement of the tool and means to pic]; up the tool automatically where the spring leaves it and move it farther in the same direction while the tool maintains operative engagement with the shoe.

Other important objects of this invention are to facilitate the presentation of the shoe to the machine, to render more easy the adjustments of the upper and the last relatively and to render -more efi'ective the upper stretching operation.

Another important feature of the invention consists in provision for closing the grippers on the upper independently of the au tomatic operation of the machine and, preferably, one independently of another. In

accordance with this feature of the invention the operator can, after positioning the work, close the grippers thereon and then inspect the shoe to ascertain if it is properly prepared for the machines operation. Advantageously the closing mechanism is arranged so that the toe an side grippers can be closed separately. This permits the operator to position the upper first within the toe gripper with the last positioned properly lengthwise and sidewise relatively to the toe gripper and then cause the toe gripper to close upon the upper and hold it while the Specification of Letters Patent.

fierial No. 539,413,

upper is being positioned within the side grippers which may then be closed.' In this procedure the operator is not obliged to place and maintain the upper in proper position to be seized by all the grippers before any of them can be vclosed. This provision is of particular value in a machine which is equipped and arranged as described in prior United States Letters Patent No. 1,080,264, granted June 18, 1910, on an application filed by me to provide gages with relation to which the last and the upper may be correctly positioned in presenting the shoe to require little or no adjustment after pulling to obtain the desired length and position of the toe tip on the last. If desired the side grippers may be closed first and the too gripper closed later. I have shown a finger operated device for closing the toe gripper and a treadle operated device connected to the side grippers for closing them and which may be connected to the toe gripper for closing that gripper also if it has not previously been closed.

Preferably and in accordance with a further feature of the inventio the grippers are, immediately after being closed, yieldingly uplifted sufiiciently to straighten the upper over and about the last and, it may be, partially stretch the upper.- This initial pulling of the upper has several advantages. lfthe upper is gripped and initially pulled at the. toe first it is thereby straightened out lengthwise of the last so that the operator can see if the upper and the last are in the desired relative lateral positions and if they are not he can easily adjust them by moving the last or the toe gripper. This first pull will also straighten somewhat the sides of the upper and enter or assist in entering the sides in the side grippersa It will also render more easy the adjustment of the sides of the upper to place the tip seam ends in desired relation to their gages so that the upper will be seized and pulled with the seam approximately straight and the tip of a predetermined length from the seam to the end of the toe of the last. When the upper has been thus seized and straightened out without'being put under heavy tension any adjustment which may be required for positioning the tip seam or any other portion of the upper by the tip (TD nail straightening mechanism or otherwise can be made without the resistance which exists from the friction of a fully tensioned,upper on thelast. Also adjustments made under these conditions more certainly shift the upper bodily upon the last, as distinguished from increasing the tension at one point and relaxing it at another, than can be done when the upper is strain.

Another feature of this invention is found in the provision for step by step stretching of the upper with a dwell of substantial extent between successive steps during which the tension becomes distributed throughout the entire body of the upper. lit is well known that if leatherfis pulled once and then after a dwell is further pulled the stretch taken out by the two pulls will aggregate more than could safely have been obtained by a single pull. in accordance with this feature of the invention advantage is taken of this fact, with the result of obtaining a pulled-over shoe that is better fitted to its last and which will require somewhat less of upper stock. Similar advantages are obtained in some degree from the arrangement by which the upper can be stretched longitudinally and transversely with a substantial dwell between the stretching pulls in the two directions.

These and other features of thisinvention includingcertain details of construction and combinations of parts will be explained. in connection with the following description of a preferred embodiment of the invention and then pointed out in the claims.

Figure 1 is a side elevation of the machine partly in section; Fig. 2 is a plan view of the gripper operating levers.

The driving mechanisms of the pullingover machine and those other mechanisms not herein specifically described may be constructed and arranged in accordance with said prior patents to which reference may be had for a full explanation of the pullingover machine or they may be constructed and arranged in any other suitable way.

The driving mechanisms comprise a shaft carryinggripper cams 2 and Each cam receives a roll 5 on aslide 6. The rear slide has an upwardly extending stem 7 encircled by a spring 8 held under tension by anut 9 against theblock 10 which receives the forked end of the updraw lever .12. There are two of the stems 7 and associated parts rising from therear slide 6, one being hidden by the other in Fig. 1. These stems held under full pulling connect with the two side gripper levers as The front appears in the plan view Fig. 2.slide 6 has a single stem 7 and associated parts connected with the reafiend of the Each of the gripper levers is fuicrumed at 15, and the front arm. of each lever is formed in two sections, that by the spring is, the main lever terminates short of the gripper attaching point, as clearly shown in Fig. 1, and the second lever, or lever arm ection, 121 is pivoted on thefulcrum rod 15 and overlies the front end of thelever 12. A connection is provided which normally unites the lever sections. This connection is shown as'in the form of a slidingbolt 20 carried by themain section 12 and pressed forwardly by a light spring into a recess in thelever section 121. A spring 22 of sutlicient strength to apply a light upper stretching pull to the gripper with which it is as sociated is arranged under tension between thelever section 121 and the front end of the other section. vers for the side and toe grippers is formed alike in the respects above mentioned and the grippers are suspended from thefront sections 121, 121, 131 and extend downwardly through guideways in theframe portion 121. The guideway for each side gripper is wider than the gripper carrier and the latter is formed with oppositely inclined shoulders reguided to normal position longitudinally of the shoe each time it is lowered. In this respect, as also in the construction and plan of operation of the grippers themselves, the

present machine is like that shown in my prior Patent No. 1,030,26-i and includes the spring which is under com 'aresslon when the grippers are openedby the downward movement of the front arms of the gripper levers, this movement being positively effected by the rise of theslides 6 as will be clearly understood.

The toegripper lever section 131 supports apush rod 30 which extends to the seat for thelatch 20 associated with the toe gripper and into position where the endwise backward movement of the rod will press the latch out of Its seat and allow the spring 22 to uplift thelever section 131 and the toe gripper connected therewith. In this up lifting movement the toe gripper is closed 170 and uplifted yieldingly for seizing and straighten-- by the spring lengthwise about the last.

ing the upper In addition which the toe gripper may be closed and initially uplifted, there is provided a 'trcadle 35 connected by a rod about onearm 36 of a rock shaft. The rock shaft has on its front side, lugs or fingers 38 arranged to engage a shoulder on thelatch 20 in each of the gripper levers. This arrangement is such, as clearly appears in Fig. 1, that depression of the treadle turns the fingers 38 downwardly and backwardly in the direetion to withdraw thelatches 20 from th seats in thefront sections 121, 131 of gripper levers. and thus free the spring in each gripper lever.

the springs uplift the gfront seetiens of ea h.

by means of which it is a to the push rod, by means Each of the gripper lemenses v rectly engaged by the fingers 38 are pivoted to the main portions of'the latches and n ormally held in the path of the fingers by light springs, as shown by full and dotted "lines in l igsll and 2.. This treadle o erated mechanism above described will ose all of the ers or Will close the side grippers on y 1" thejtoe gripper has been proviously closed by the o eration of the push Irod 30,, If it is desire is to close the side grippers first-and the toe gripper at a later time the shoulder-carrying section of the latch fort-ho toe gripper will be turned downwardly about its pivotal connection to the main portion of the latch and a suitable wed 'e or other device inserted in the joint at the. upper side of the pivot. Whenever this wedge is'w'ithdrawn, the. spring at the lower side of the pivot Will force the shoulder again into position for the latch, of the toe gripper lever to be operated by its finger 38. With this construction of the maclune, the 0 orator may first position the shoe with relation to the toe gripper, the inner ed of which is preferably concavecl to assist in centering the toe end of the last, and then, while holding the shoe in correct relation to this gripper, may actuate the push rod to trip thelatch 20 for cousin the toe gripper to be closed. and uplifted for lnl? tially pulling the upper.

tory fox-Ward pulling has beenirequently done by the use of hand pincers just before presenting the shoe of thennaehine. This invention enables the machine'operator to dispense with such use of hand a incers by moving the machine gripper or last, In. this movement the upper is straightened longitudinally of the last and the sides brought into condition for being conveniently positioned in the side grippers. This positioning may advantageously be eii'ected I by the" two hands of the operator, one at ither side of the shoe, inasmuch as the upper. is held and the shoe partially supported by the toe gripper and the usual heel rest of the pulling-over machine. When an upper having a tip is ,beingpresented the operator may-position the tip seem at the two sides of the shoe with relation to the front edges of the side grippers to obtain preparatory to the 1I1S8li7 1011 of the npper nto the side grip-- pers. Prior to this invention such prepararise of theffront ends of and are forced backwardly the desired angular relation of the seam to the longitudinal axis of the last sired length of ti 4 It" should be urther explained that the machineherein shown is provided with the means, including a hand lever 160andcon-- nections to the sole rest126 for actuating the,

sole rest as shown in saidprior patent No. 1,029,887. This means may be employed for moving the last. lengthwise, within the gripped and lightly held upper for positioning the last and the upper as a whole before the final updraw.

In the foregoing statement it has been as-' sumed that the shoe innersole has been tacked to the last as isccustomary in the better grades ofshoes and that the last may be moved by the sole rest through its conand the deneotion. withthe inner-sole. If the innersole is loose on the last bottom, as in some kinds of shoes, the sole restfand its actuating mechanism may be employed for positioning the inner-sole -'lengthwise relatively to the last and the apps The machine is equipped with the usual tip straightening mechanism comprising.

thehand lever 292 andrack bars 250, 256 I fully shown in said prior patents for moving the side grippers lengthwise of the last in opposite directions to effect any adjust ments of the upper longitudinally around the last which may appear to be required afterthe upper has been pulled over the last under initial tension. The grippers can also I '1 be manipulated by the handles on the front In the broadest-aspect of the invention it is not essential that the toe gripper pull the sections of thelevers 121, 131 for shifting the upper transversely of the last. These adjustments can be made While the upper is held under initial light tension by the springs 22 after thelatches 20 have been tripped by thedevices 30, 35.

An important advantage is gained by the I provision furnished by this invention for adjusting the last and upper relatively while the upper is held under a light tension. The adj ustmcnts are thereby more easilyefiected. but perhaps the in the fact that the upper is positioned in correct, or substantially correct, relationto "the last'before the main or final stretching greater advantage is found operation so'that the upper is stretched and shaped tot-he last inits permanent thus providing a better fitted shoe.

The machine is also equipped with the, starting and stopping mechanism, including the treadle X, of my earlier patents by position,

which rotation ofthe cam shaft ',-may be i caused to pull down theslide 6 and, yild ingly through springs 85 pull down the rear-'- ends of the gripperfllevers 12'and 13.- In this movement, which is accompanied by a said 4 levers,v the faces 24 ion the sections, 121, 131 until they reach latches 20 engage inclined lower sides of the. gripper chine may then come to rest arms oflevers 12 'and 13, the springs 22 are again put under tension until contact is made between said arms and the sections whereupon the latter will be uplifted for further raising the grippers to effect full stretching of the upper. The maautomatically to permit reexamination of the shoe and any further ad ustment that may be required after this second step in'the upper stretching operation, 'or this automatic stop in the machines operation may be dispensed with and the machine caused to proceed to overdraw and fasten the upper in the manner described in said prior patent.

From the foregoing description of the machine, in which its operation is also explained, it will be seen that the grippers may be closed and lightly/uplifted successively or simultaneously by the use of tripping de vices under control of the operator, and the shoe materials and the last may then be relatively positioned and .the final or full stretching of the upper machine as a second step. after the starting treadle X has been depressed. The arrangement by which the stretching is effected in two steps with a substantial dwell between permits the upper to take the form of the last under the initial tension of the first step and enables more stretch to be taken out of. the upper in two steps than could saiel y be done if the upper werepulled in a single step. It will be noted that in the power driven operation for efiecting the second pulling step, the springs 22, which are inthe initial operation, are put strumental in under tension and secured under tension ready to be trippedin the work upon thenext shoe presented to the machine. Stops arcprovided on thelever sections 121, 131 to engagecushions 122 on, the frame otthe machine to prevent danger of breakage it the tripping devices are actuated when no shoe is in the machine. When they are so actuated the springs 22 are liable to throw the lever sections upwardly with considerable force.
