METHOD OF AND MACHINE FOR QPERATING U PON SOLES Filed July 1, 1927 2 Sheets-Sheet 2 Fig. 2.
' of the sole.
To insure uniformity in the widths of corresponding parts of the reduced areas along the opposite lateral margins of the shank portion of the sole, and also to provide for 10- cating the ends of the reduced portions at the desired predetermined points, the invention in one of its machine aspects consists in the provision of means for operating upon the margins of soles, comprising an operating tool, a sole supporting templet, and uv gage, the operating tool and the templet being adapted for relative movement to transfer the point of operation of the tool along the margin of the sole, and the templet having a portion wider than the sole to control the operation of the tool at one part of the sole margin and another portion'narrower than the sole to enable the sole itself, in eo-operation with the gage, to control. the operation of the tool at another part of the sole margin. 1
As herein illustrated, a rotary cutting tool is arranged to co-operate with a sole supporting templet which is adapted to be manipulated to cause the margin of the sole to travel progressively past the cutter, and a table, inclinedrelatively to the axis of the cutter, is arranged to support the templet so that the cut will be made at an angle to the surface The illustrated gage consists of a roller mounted upon the table and arranged to project above the templet into the plane of the sole, and the templet is made larger than the sole at the forepart and heel portion to hold these portions of the sole away from the cutter. t its shank portion, however, the templet is narrower than the shank portion of the sole toenable the gage roller to leave the templet and engage only the edge of the sole, thereby gaging the cutting operation along the shank from the sole itself instead of from the templet. Between the forepart and shank portion of the templet and between the heel part and shank portion of the templet the opposite. margins of the templet are shaped to co-operate with the gage roller to cause the cutter to begin and end its cutting operations at the desired points at the ends of the shank portion of the sole.
Invention is also to be recognized in the provision, for use in a shank. reducing machine, of a sole supporting templet having means for holding a solev in fixed relation thereto, the templetprojecting beyond the a toe and heel portions of the sole to hold corresponding portions of the sole away from an operating instrumenta-lity'of the machine and having a shank portion which is narrower than the shank portion of the sole and which is arranged relatively to the latter to permit a. reducing operation tobe gaged from the edge of the sole itself. I
The invention will be explained with reference to the accompanying drawings, in which Fig. 1 is a view in side elevation of a machine embodying the invention in certain ofits aspects and showing also the templet with a sole positioned thereon, the templet and sole being in section in the vertical plane of theaXis of the cutter;
Fig. 2 is a front elevational view of the machine; I
Fig. 3 is a plan view of the templet and the work showing the templet resting upon the work table and being guided by the edge gage roll and showing the work being operated upon by the cutter;
Fig. 4 is an edge view of the templet and the work; and
Fig. 5 is a cross-sectional view taken along the line V-V of Fig. 4:.
In Figs. 1 and 2 of the drawings there is shown the head 8 of a rotary feather edging or shank reducing machine, such as that disclosed in United States Letters Patent No.
r 1,003,981., granted Sept. 26, 1911, on applicaend a cutter head let. The shaft 12 is adapted to be driven from any suitable source of power by means of a belt 16 passing over a pulley 18 fast on the shaft between the bearings 10. The construction of the parts thus far described is substantially the same-as that of corresponding parts shown in the Letters Patentabove referred to.
The illustrated cutter head 14 is of the so called barrel type, being of substantially cylindrical form and being provided with a plurality of cutter blades 20 having cutting edges pi'ojlecting beyond the periphery of the cutter To position the work at such an angle rela 'tively to the axis of the cutter head that the blades 2O will bevel the margin of the work there is provided an inclined table 22, and to guide the work while it is being moved inanu ally past the rotary cutter so that the shank reducing cuts will be located as desired there is provided a templet or pattern 24 which is adapted to support and carry the work and to c'o-operate with an idle edge gage roller 26 on the table.
The table 22 is mounted'so that its inclination may be adjusted to vary the angle of bevel of the reducing cut. To this end, the rear portion of the table is pivoted at 28 to a block 30 carried. by a bracket 32 which is secured to the front portion of the head 8 below the cutter shaft and the front portion of the table is connected by means of an extensible link 34 with a collar 36 carried by a hand screw 38, the shank of which is threaded through the lower portion of the bracket 32. The link 34 is pivoted at 40 and 42 to the change the inclination of the table 22 by manipulation of a right and left threaded turn huekle 44-, which coil. ltesthe iilitldle portion of the link. i i
Prerision is alsoniade whcrehyany change ingular or tilting adjustment the H ole 22 may be compensated for by appropriate vertical. and horizontal adjustment ot'the table and whereby the table may be adjusted to accommodate soles of different 7 thicknesses and. widths. To-efiectthe vertical adjustment of the table its pivotal supports 28' and are adapted to be moved in unison. hy adjustinent vof the hand screw 38 and forv this purpose the collar 36 and the block 30' j are connectedwith the hand screw for upandi-down movement in unison therewith the coma-r36 being confined between the head of the hand screw and a collar 46 pinned to the shankiojt the screw 33, while vthe block lO is ponIiI'iMlbetweenla collar48 and a nut 50 each cl which is secured to the hand screw. Toloclc the table in its vertically adjusted position whindihg screw 52 extends through a vertically elongated slot 5-1 in the bracketSQ rand-is threaded into the block 30, the bind ing screw 52heing provided with a suitable checknut '56. I
To enablethe table 22 to be adjusted hori zo 'itally, the. bracket- 32- is threaded' upon the .i'orward extremity of a horizontal adj Listing screw 6,0which extends through thehead 8 and is held ag inst lengthwise displacement by n'leans of an ar1n62 rigid with the head 8 and=arran'gedto straddle the screw hetween the :heaul 64 ofthe' screw and a'collar 66- pinned. to the shank portion of the screw. The bracket 32' is held agaiustturning about the adjusting screw 60 by means oi: a stud: 68 which extends from the rear (Ff-tile bracket'32iinto a socketin a portion ofzthe head 8.- To look the table in its horizontally adjust-ed position a binding screw 70 is provided,th'e end of which is a-rrai'lged to engage the sh ank of" the adjusting screw The telnplet 24'- consists of flat 1 plate which isadapted to support a sole while the sole is being operated'ugon the outline of; the 'teniplet correspondingin a general way to Etheloutline 0f the-sole except'thatthe portions. of the teinplet which support the forepart: and heel portions or the sole are wider than the'correspond-ing portionsoi the sole for the purpose ofi'h'olding these portions of I thesoleiaway from the reducing knife while that partof the-ten1pletwhicl1 supports the shank portion of the sole'is'narrower than the corresponding portion of the sole to in surelthatthe: edge of: the sole rather than the edge. otthe templet will engageth e gage roller 26 to guide the,work jduring operations-upon the-[shank of the sole: To posi tion the :-.sole 1 upon: the templet an d positively? to hold llllGglrSOiiG a gainstgedgewise I displace G1 nie-ntrelatively 't oztheilteinplget'while tl re 'solef rearward of the heelbreast line H are spaces 1 tei'npletlslope} inwardly toward th'esole edge.

edgdfofzthe sole-at the shank where the sion is made for flattening out the edge of the sole and insuring that it will be held in contact with the templet while it is being operated upon. This result is accomplished by means of a presser foot 7 8 (Fig. 2) havi mg a curved work-engaging portion located just in advance of the line of contact of the cutter with the work and arranged to travel along the margin of the sole as the sole is fed past the cutter. The presser foot 7 8 is provided with a vertical shank portion 80 slidably mounted in bearings formed on a bracket 82 carried by a guard 84 which encircles the cutter and is suitably mounted upon the head of the machine. The presser foot 78 is urged downwardly by means of a spring 86 secured at one end'toa portion of the bracket .82 and at its other end to a collar 88 fixed to the shank ofthe presser foot. The collar 88 by engagement with the upper portion of the bracket 82 functions to limit the approach of the presser foot and the movement of the presser foot toward the table 22. As shown, a forked projection 90 on the collar 88 slidingly engages a vertical stationary guide rod 92 to hold :the presser foot from turning in its bearings in the bracket 82- If desired, and as herein shown, a second presser foot 94 may also be employed to hold the sole against the templet and the templet against the table, the second presser foot 94 being arranged to gage the sole at a point substantially opposite that being acted upon by the-cutter. The presser foot 94 is shown as being mounted in a bearing 96 formed at the front of the guard 84 and'it is urged downwardly by means of 'a suitable spring (not shown) which maybe confined within the bearing 96 and the tension of which may be varied by means of an adjusting screw 98.
The cutter guard 84 may be adjusted axially of the cutter to vary the transverse relation of the presser foot to the work. As shown, the cutter guard 84 is secured to a horizontal shaft 100 slidably mounted in a bearing 102 .iformed at the upper portion of the head 8 by'means of an adjusting screw 104. The shaft 100 together with the cutter guard 84 and the presser foot carried thereby may be adjusted. A binding screw 106 is pro- Tvided for securing the shaft 100'in adjusted position.
In using the apparatus herein described for shank reducing an outsole for a McKay sewed 'shoethesole, after being grooved and chaniziele'd in the usual manner upon the grain side,
is placed channel side down upon the templet with the toe and heel ends of the sole engaged and located by the curved shoulder 7 4 of the templet and the sole thus held against edgewise displacement relatively to the templet. The templet is placed on the inclined table 22 and positioned with the edge of the pattern at the heel end against the gage roller 26. Vhile holding the edge of the templet continuously against the roller 26, the operator manually feeds the templet in the direction of the arrow in Fig. until the entire margin of the templet, except the portion at the cx treme heel end thereof, has been moved past the gage roller. At the beginning of the operation the portion of the templet at the heel end of the sole holds the sole away from the cutter so that the latter is permitted to act upon the sole. When one of the portions of the templet reaches the roller, however,
the sole is moved into the path of the cutter at such a point that the cutter begins its shank reducing action at a predetermined point, preferably at the heel breast line. The sole is brought into contact with the cutter by movement of the sole toward the cutter in the plane of the sole or, in other words, by edgewise movement of the sole. Inasmuch as the templet is narrower than the sole at the shank, the edge of the sole is brought into engagement with the roller 26 very shortly after the cutter has begun its operation and there after, throughout the length of the shank portion of the sole, the sole is guided relatively to the cutter by engagement of the roller 26 with the edge of the sole itself. As the forward end portion of the shank of the sole is brought into the field of operations of the cutter. one of the curved edge portions 76 of the templet engages the roller 26, causing the sole to be moved away from the cutter at such a point as to terminate the shank reducing cut at a predetermined point, preferably at the ball line. The templet then serves to hold the sole away from the cutter until the .along'the shank is gaged from the edge of the sole itself instead of from the templet.
Having thus described my invention, what I claim as new and desire to secure by Letters edge of the Patent of-the United States is:
