UITED STATES PATEN `MACHINE FOR ATTACHING MOLDED COUNTER-S T TURN ySEIES.

Original application led March 7, 1922, Serial No. 541,667. Divided andthis application filed September To all whom t may concern.'

Be it known that I, MILTON L. DODGE, a citizen of the United States, residing at Newburyport, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Machines for Attaching Molded Counters to Turn Shoes, of which the following is a specification.

rIhis invention relates `to machines par-` ticularly intended for attaching counter stifener's and shank pieces in position in the uianufacture of turn shoes, and by which this operati-on may be rapidly and accurately effected, this application being a division of l5 applica-tion Serial Number 541,667 filed March 7, 1922, method for attaching molded counters to turn shoes, inwhich the method herein disclosed is claimed. Heretofore these parts have usually been attached while the last is in the unturned shoe, the shoe `being supported in a nailing machineby a jack having in its top a pintor engagement in hole in the neck of the last.

, movable forwardly for the placing and removal of shoes and is then moved backwardly and raised up into cooperative relation to the'nailing mechanism at each operation. v

' As is well known to those skilled in the ar-t the position of the last pin hole varies greatly with different lasts and the lasts also vary considerably in height.` In 'order to take Careof the variations in the position of the last pin holes laterally of the last, it has M been proposed to mount the last pin ina block free to slide laterally' of the jack so that the operator may move it laterally as it `approaches the nailing mechanism to cor-v rectly position it. The proper lateral positioning of thisblofck, as well'as vertical adjustments for varyingl heights of last requires considerable skill and care on the part of the -operator and slows production very considerably.

is removed before the counter is attached,

and va block, fitting easily within the heel portion of the shoe, is fixed rigidly to the top of the jack. The engagement ot the upper at the heel end of the shoe about this block thus properly centers the shoe so that it is Valways presented in proper position laterally to' the nailing mechanism, no adjustment being required for different shoes.

ing of the shoe relative to the nailing mechanisms, a centering guide may be employed against Vwhich the shoe is moved ybeneuith the nailing mechanism.

By this invention, ther of the counter in correct po. lto a mechanical operation in wh. ercise of special skill or judgmen sary, so that the operation v nia.- ifi speeded, the productifniv of impcrtect or im $5 erior work eliminated, and a poorer quality of labor may be employed satisfactorily. thus materially cheapcning the operation. L F or a more complete understanding or" .this invention, reference maybe `had to the ac- Je companying drawings inwhich f Figure l is a fragmentary side elevation of the machine showing the relation of the shoesupporting jack to the nailing mechamsm. i i i t Figure 2 is a detail plan ci? the sole and counter gage. A i

Figure 3 is a side elevation ot the shoe supporting block used when wood heels are to be employed, other parts being shown in s0 dotted lines. f V Figure 4 `is a top plan of a block used where wood heels are to be employ-ed.

'Referring iirstvto Figure l, at l is indicated a jack post which is slidable forwardly e5 and rearwardly in suitable guides on the vertical movable slide 2.y This machine mav` he of any suitable type of nailing machine, as

yherein shown it being of the well known lightning type.. The jack l has at its Q0 outer end an upwardly extending post 3 which, in the ordinary use or" the machine for nailing heels, is used to supporty the toe of the shoe. At 4is shown an adjustable heel post to 4tho top of which is fixed a block 95 5.. This block inthe present invention isy rigidly fixed to the top ofthe post 4, centering pins 6 and 7 being shown to insure its correct positioning and a set screw 8 being employed to fasten the block rigidly in position. At 10 is shown a nailing block which is designedto receive nails in suitable perforations therein and to receive drivn ing members for driving `the nails into a shoe supported on the jack l. rihis block V35 10 is preferably provided on its lateral sides with downwardly extending tingers 1l and on its rear tace with a finger 12, These iingers may be yof springy material, if desired, so that a molded counter, indicated by 1.1.0

dotted lines at 13, may be pushed upwardly over the block 10, the fingers ll and l2 passing outwardly thereof to retain it in position. Where shank stiieners are to be attached also, these are assembled with the counters before the latter are positioned for attachment-to the shoes. This nailing block,

together with lingers, is Xed in position on the machine in a well known manner. i The jack l may be moved outwardly, away from beneath the block 10, into the position shown in dotted lines, to faciiitate the placing of the-shoe thereon,kthis being done when'the slide `2 is depressed below cooperative relation with the nailing block. lWhen the jack is in this position, an unturned shoe, the

last having been removed, is placed over shoe sole is correctly related to the path ot movement of the jack so that it will be brought into proper cooperative relation with the block'lO, and the counter thereon, without particular care on the partei1 the operator.V

The jack is moved rearwardly beneath the nailing block and the sole of the shoe engages between outwardly curved spaced." arms 2O (see Figures 1 and 2) or a gage 2i.V

This gage 2l is ixed to the upper end of a rod 22V which extends through a guide flange V230 fof a vertically extending track orguide member 23 against theV forward race of which the gage slides. The rod 22 extends downward c through an opening 2a of a bracket 25 which is fixed centrally to a top cross member 26 ot a yoke 27 made'fast at opposite-ends by inturned flanges 28 to the top'of the Vslide 2.' Slight variations in. the

' thickness of the sole are provided for by a spring 30 surrounding the rod 22 and bearing in its lower, end against the top face of the bracket 25 and at its upper end against a pin 31 extending transversely of the rod 22. This vertical movement is for the purpose of correctly positioning a counter-engaging. gage or centering plate 35, which is also carried by the rod-22 against the upper face of the gage 21. The gage 35` has a sloping'inner face 36 which engages beneath the rear end of the counter to properly position it relative to the sole 'in a lengthwise Vdirection so that when the `iack l is pushed rearwardly and the slide 2 raised upwardly, the parts are guided automatically into proper relative position.V The nailing mechanism is then actuated to drive the nails in `the block 10 through the sole-engaging flange of the counter in the usual manner to make 1t tast on the upper race of the shoe sole.

- it is sometimes desirable to move the gages 21 and 35 out or cooperative position with the jack and nailing block, as when shoes to which wood heels are to be applied, are being operated upon. For this purpose the guide member 23 is Xed to the outer end of a screw i0 which is slidable through perorations in a pair of spaced `iaws 4l upstanding from a bracket 42 which Vis made "fast to a fixed part ot' the machine frame 43'. rThreaded on the screw 40 between the jaws il is a knurled nut d4, by turning which the guide member 23 may be moved tor-V Vwardly or backwardly relative to the niachine frame and into and out of cooperative relation with the'jack and nailing block. In order to permit this motion without binding, the perforation 24 of the bracket V25 through which the rod 22 passes is formed daring outwardly toward both ends from an intermediate position to permit ready rocking of the rod 22 with reference to the bracket. The position ot` these parts when the gages are out of operative position is shown in dotted lines in VFigure 3 in which also a modified construction of jack block particularly intended for use withV wood heels is shown at 50.

As is well known the outer edge of 'theV heel portion of the shoe'to which a wood heel is to be attached is beveled loil, 4and betere the shoe is turned'the upper is unattached tothe heel portion ont the sole. When a wood heel is VIto be aiixed therefore, the block rhas a marginal upwardly extending iange portion'l, as shown in Figures 3 and et, withinwhich the sole extendsand against the top of which the edge of the counter may rest. The block dinayY be of a width sutlicient to substantially fit the width of the sole if desired, as shown Vin full lines in Figure 4, but in order that-a single block may serve for several sizes of shoe and therefore recpiireY infrequent change of blocks for different sizes, they may be made somewhat narrower than the shoe to be operated upon as indicated in dotted lines at 52 (see Figure 4t). When such a narrow block is elnployed itis an easy matter for the operator to center the sole laterally-on the block by placing his fingers beneath the edge of the sole and in contact with the edge of the block, the upper, as before stated, being unattached at this point to the sole and offering no obstruction to this action. The sole and counter gages are not used at this time, and in order to position the jack correctly rearwardly beneath the nailing block with these gages out of position, an adjustable stop herein shown Vas comprising a Vcap screw 55 is kthreaded in a boss 56 projecting vinwardly from the yoke member 26. This cap screw may be adjusted and then fixed in position by a lock nut 57 thereon so that when the jack 1 is pushed inwardly to impinge on the head thereof, it is correctly positioned for vertical movement into operative relation to the nailing block. While as before stated the last is removed prior to the attachment of the counter and before the shoe is turned, it is usually preferable to turn the toe portion of the shoe before the counter is attached, this being shown in dotted lines in Figures 1 and 3. When this is done the toe portiony may be supported, when the shoe is initially' placed on the jack, by means of the toe rest 3, and when 'the jack is moved upwardly and the sole is engaged between the heel block and the nailing block, the forepart of the shoe is raised upwardly off the toe rest by the engagement of sole and counter between the blocks 5 andlO substantially as shown. If the forepart of the shoe is not turned prior to the attaching o' the counter, the toe rest is likely to intertere with the downwardly extending uppe v of the shoe.

Having thus described certain embodiments of this invention it should be evident 'to those skilled in the art that many modifications and changes might be made therein without departing from its spirit or scope as defined by the appended claims.
