s v '25 Claims The present invention relates to. shoe supporting jacks and'particularly to improvements in devicesfor positioning a templet for guiding a shoe engaging tool about a jacked shoe, as in the .ma'chine illustrated and described in the U. S1

Patent'to, Alfred R. Morrill, No. 1,897,526 dated February 14, 1933.

r In the machine ofthe Morrillpatent'the lasted shoe is supported upon a-toe rest-and a heel support, and a templet is securedto the bottomof the shoe by a .clamp member pressing the. templet downwardly against the shoe.- The tem plet is located in position on the surface of the shoe at the toe end by the conical end of 'apin carried by the templet,-engaging an indentation in the bottom of the shoe, and at the heel end by the head of a pin passing through the sole of the shoe and into thelast which supports the shoe. The heel end of the templet is slotted and surrounds the head of the pin, thus preventing lateral movement. The 'lastemployed with the templet in making the shoe is provided with a positioning hole in its bottom'surface to locate the templet properly when the pin is inserted. The last must therefore be specially drilled for use in this type of machine. I

'An object of the present invention is to provide a 'novel and improvedjack for supporting a templet in predetermined 'positio'non the bot torn surface of a shoe carried by a last of ordi-' nary commercial type" in which no special templet positioning pin hole has been formed.

Another object of the-invention is to provide a novel and improved automatically adjustable gaging device for positioning'a templet .on the bottom surface of a shoe, and for retaining the templet in the desired position throughout the which the templet operation or operations for is employed.

With these objects in view, a feature of the present invention contemplates the provision in a jack having a heel support and toe rest on which a lasted shoe may be secured and'means for clamping a templet against the sole' of the shoe, of a gaging device, cooperating with the sides of the shoe upper for positioning'the templet on the shoe sole. As hereinafter described,

the'gaging device .for positioning the templet is provided with a member engaging the slotted end of the templet at the heel end of the shoe.

The jack of the Morrill machine is provided with a clamp mounted on an arm pivoted on .the

jack to permit the clampto swing towards and from operative position, so "that the shoe may readily, be removed from the jack at the end 61' the operation on .the' shoe.

'- While the gaging devices of the present 'invention may be considered broadly to include any suitable means. for positioning the shoe by engagementwith a templet on the shoe and by" contact withthe sides of the shoe upper, and may be associated with the jack in any suitable man- .ner, a further feature of the invention contem plates mounting the gaging device on the armwhich supports the clamp, so that when the clamp is moved towards operative position, the gaging devicewill automatically be moved intocooperationgwith the shoe. To facilitate proper positioning of the gaging device in accordance with this feature of the invention, a guideis provided, for the clamp arm on the jack, arranged to frictionally engage the clamp arm and hold it in -the; position to which it is moved before the clamp isactuated; In order to employ thegaging'device with different sizes of shoesand to prevent the. operation of the clamp by reason of its re- I silient connection with the jack from affecting the gaging'device, the gaging device is pivoted to the clamp arm for movement toward'sandi from the bottom surface of the shoe, and the templet'engaging member ,of the gaging device; Y

isv causedlto move into contact-with'the templet y when the clamp is brought into operating posi tion by. means. acted on by theheel'endofthe shoe. .The gaging device is also'so mountedon theiclamp supporting arm, that it may move] bodily parallel to the plane of the shoe 'soletoaj' positionidetermined' by the gage members.

A:further feature of the invention contem plates the provision in a gaging device for positioninga templet on the bottomfsurface of the.

shoe, having gagesconnected together to move in opposite directions laterally of the shoe, and" ajtemplet'centering', gage, of means for auto' matic'ally preventing movement of the lateral gages after being brought to gaging. position.

The means for preventing-movement of the gages.

may consist 'of any suitablearrangement-for locking the gages in place, and-in the form' shown, mechanism is provided for fr'ictionally' preventing movement of the gages as a result or thrust on the templet centeringf'gage.

- Other features of the invention consist in the novel constructions,-;combinations and arrange-1 ments of" parts hereinafterf described and claimed, the advantages ofwhichwill be understoodby those skilled-in theart from theffollow;

vice taken along the line l-"l of Fig. .5; Fig. 8

is another sectional view taken along the line movable towards and from thetoe. rest 2" for securing arr-inverted lasted shoe, indicated 'at- ID, to the jack. The heel support-is p'rovided with a last pin 9. arranged to engage the. pin hole in the last and to be operated to lock'the To'releasathe shoe,.a releasing finger i4 is located onthe toerest justbelow theshoe; Since the specific construction and operation of the shoe supporting mechanism oftheijack is immaterial so far as the present invention is" (3011-. cerned, further description and. illustration has been omittedfrom this application. 1

.As; in the'machine of..the Morrill patent referred to, thejack may be mounted to tip and turn. and be moved to feed the shoe'with respect to any of a numberof operating devices such as an edge trimming cutter, indicated diagrammatically in Fig- Z at it. The contour of the. sole on the shoe-is shapedby' the. cutter l6, and'the shoe isguidedby thetemplet i8 onthe bottom surface of the shoe; theshoe being forcedto-' wards the cutter until stopped bya guide indicateddiagrammatically in Fig.2 at l9, fixed'to the machine to cooperatewiththetemplet l8.

The templet is secured against the shoegby a;

clamp mounted on the upper end offa supporting. arm 22 and actuated'bya cam lever 24 on the arm." The arm 22 is forkedtat its lower end and is, pivotally mounted on the j'ackiat 26 to swing towards andfrom'a position in which.

the clamp 20 may cooperate with the templetto To locate the toe po' rtionjofi the templet on the bottom of theshce 'theitemplet is provided with apointed 'set-screw or pin 28 projecting from the sole engaging 'surfaceof the templet,

into an indentation formed at a predetermined location in the surface ofa; sole.

In accordance with a feature of theipresentv inventiompthe heel end of the templet is located and held in predetermined position "on the shoe.

by. gaging means cooperatingwith thesides ofthe shoe upp'e1":and;with;the inner surfaces of, a slot, 30; formed substantially parallelto, the sides of. the shoe at the heel and of the templet and to thgfipg h 9 the mple he a g. meansis supported by a frame composed of a pair of horizontal cross bars 32 and 34 (see Fig. 7) secured together by screws 36. The gageframe is connected to the supporting arm 22 for the templet clamp 20 by parallel links :38, a block), and a pivot shaft 42 passing through and secured to a lug- 01 the arm 22,; and journalled -at its ends in upstanding lugs on-the block 40. When the .clamp 23 is moved into operative position, the "gaging means :moves with the arm 22 into contact with the shoe. I

To locate the templet in a central position on the shoe, the gage member which cooperates with the slot 39 of the templet comprises an arm 43 extending from the gage frame over the heel end of the'shoe. The position of the arm 43 relative to the shoe is determined by the gage members which act on the sides of the shoeto center the arm 43, on the heel.

The members of the gage which cooperate with '52- fixed by screwsili, to 'the lower cross bar 34 of thegage frame, so. that the block 5i; is caused to move in. a straight line on the frame producing equal movements of the levers, 64. The arms of the gage levers 44 which cooperate with'the sides of the shoe are, when no shoe is between them,

423, permits the gage to'be maintained'in the same angularrelation to the shoe when these links, swing on their-pivots, and the spring 54.

being shorterthan the links serves to maintain the gage as a whole in an" intermediate position; relative to the clamp supporting arm 22 when not, engaging the shoes; 7 V

I The-gage is also movable on the clamp supporting arm towards and from the bottom surface of the shoe about the shaft 42; which, passes loosely into thejends ofthe block 49. When the gage is disconnected from the shoe, it is rocked about the; shaft 42 to move the gage upwardly away from the templet on the shoe by a spring 51 compressed between one end'of a passage in the arm 22 and a projection on the block d!) which rotates.

abouttheshaft 42 and forms a part of the mounting for the gage. When the gage is moved with the arm 22" towards the heel of the shoe, the lateral gage" levers '44 contact with either side fof" the upper at thef'heel end'of the shoe. ,To

cause the gage to be moved downwardly towards the shoe bottom against the spring 51, the gage is provided with a plate 58 against which the heel end of the'shoe bears after the levers 44 engage the. sides 'of the upper. When the gage is moved with the arm 22 away from the shoe, the up ward movementgof the gage by' the spring 51 is The ' supporting post by a pairof springs BZcarried by upper edge of the guide 68. r

In order to permitthe position of the templet limited by a set screw 59 mounted in a mg on the arm 22 in a position to engage a projection on the threaded into each part, respectively, of the forked end of thearm and engaged at their inner ends in recesses in a two part block surrounding the supporting post 4 for-the jack. The parts of the block so are secured together by scre'wsfil to slide vertically on the post 4 and the block is yieldingly maintained in lowered'positionon the the block and engaged at their upper ends by a split collar 64 fixed to the supportingpost-L To limit the downward movement of the pivot sup-- porting block 6%, a second split collar '66 is'secured to the supporting post beneaththe block 60. When the clamp 2F} templet E8 on the shoe, the arm 22 is raised slightly with the block 60 to compress the springs When the shoe is released from the jack, the heel support 6 is moved away from the toe rest 2 as shown in Fig. 4. The toe of theshoe is lowered relatively to theclamp 29 so that the clamp releases the templet l8. To limit the movement of the arm 22 after the shoe is released the lower part of the arm cooperates with an arcuate guide 68 connected at one end by a pivot 10 tothe lower end of the heel support 6 and surrounded by the forked. lower end of the clamp arm 22. The

free end of the guide 63 is hooked and is engaged by a pin H passing through the arm 22, when the arm is-in its lowermost position. To assist in positioning the gage and clamp, the'guide 68 is forced into frictional engagement with the pin:

H by a spring pressed plunger 12 slidablymounted in the clamp arm andarranged to engage the to be adjusted for different shoes styles or rights or, lefts of the same style, the templet centering gage arm 43 is formed at its forward end with a spherical surface of a diameter to fit closely within the slotted end of the templet. The arm 43 may thenbe shifted at an angle to the length of.

the templet while still retaining a close-fit with the slot 30. The templet gage arm is releasably clamped by a screw l4 tothe upper end ofa shaft 15 mounted in the upper frame cross bar 32, the lower end of the shaft being connected to a guide block 18. By loosening'the screw 14 the posi- 'tion of the templet relative to the center line of the shoe when the lateral gages contact with the upper may be regulated.

The gage arm isheld against rotation with the shaft 16 by the block 59 in which is formed a slot edges to fit more exactly with the sidesof the slot 88.

During the operation of a machine in' which the jack is supported, the edge trimming or other operatingtool is guided about the shoe by is actuated against the faces on the templet the-engagement of the fixed guide I 9 (see Fig;2) along the edges of the'templet'. When the heel end of the shoe is re'ached;fthe thrust on the templetproduced by the guide 19 is imparted .to.

the templet centering gage arm 53 and to the guide block 18 connected with the gage arm, n

The block 50 is also rotated slightly and is thus also held from movement with the guide block 18 by the guide member 52 on the cross bar 34.

Due to the frictional engagement of the blocks 18,158 and the guide member 52, the gage levers B4 are locked against separation from the shoe so that the thrustof the fixed guide ion the templet is automatically resisted by the-gage. The greater the pressure on the templet; the greater will be the frictionaleffect produc'edin the gage so that there is no possibility of shift ing the templet relatively toJtheshoe whilein use. At the end of the operationtheiiack being I moved away from the guide! 9 in the same ma'nf-f her as in the machine of the Morrill patent, the
