(01. 12 142)- :This invention :relates as methods 16f -tsole :Mn'rHonFonnotmnmemnn;songs f .roundingpand hillustrated herein with refer- .the-lattenfrom "thebottom of .the sole through the .upper margin thereof. The :shoe 'is'support- .ed against the thrust :of the knife by a =feeding member. commonly called .a :feed ,point, which enters the =welt "crease and engages the upper margin of the sole or welt zoppositelto the knife. When-the-machine is inproper adiustmentthe :knife and feed point. justzmeet-at the: end of the cutting stroke of the knife.
:However, all the cutthqgstrokes .ofithe knife are :not of precisely the same .lengthibecause of the islacktin the joints of the ';driving mechanism resulting from the usual'bearing clearances, and the wear which accompanies the ordinary use ofithe machine.
Consequently, the knife, from time to time, 'will engage the feedpointr making a: shallow. indentation therein. This tends to dull :the knife. llponibeing dulled, the effectiveness :of .the knife is diminished :not' only :for this; reason, but also because the knife -is shortened, ."causing ,the rounding cutto be incompletezatithe upper-zmar- :gin of the .sole. until the i knife :is .;r.esharpened and readjusted, there may be :azthin fringe or projection extending from the :upper ridge :of the sole aedge at lNEIiOlIS points :along it 'which 'should betrimmeditherefromzin order that theiproper guidance act the shoepiduring .the

However, mechanism is not to be. claimed herein, .butlforms @the subj ectmatter of my applicationlserial No.1210;395, filed on February 7 .10, 1951, -.a division -.0f this application. g
.The :aboue :and-otherieaturesaof :the invention .Will now he -described detail with reference to the illustrative. machine shown. in thea-ocompanying drawin'gs, and will be defined linnthe claims. 7
In .the drawings,
Ti-g. -1j is 1 a; side -.elevation:.of ia .tp'ortion-of the head of a rounding and channeling :machine embodying theinvention;
Fig. 2 is asectional .-.plan view, .the,..section being taken horizontally at-rthe .levelofthe chopping knife through the sole and the .feed .point;
and g '3 is a :rear elevationzaof the rfeed point, illustrating the relation of-. the. spnr-thereon(and the rounding cutmademponrthesole. In the eillustrated. -machine, :Wh-iChii-S the same asthe--above-amentionedPerrymachine except as will-v be specifically pointed: cutbelow, l0 indicates the continuously;reciprocatingtchoppingtknifc, l2 the-knife carrier, 14 ithe slideway.;in- -which (the carrier move horizontallmxl 6 the -bottomrest. 18 .the oscillating support for :the bottom rest, the feed point, 22 the icreasesguidefiandzdthe .forepart guide. As usually ccnstructedptherfeed point has --set into itsrearward side awwork-engaging plate 16 which positioned 1v on the feed point by dowels 528 91,116,318 :secured thereto :by a screw-30. I
The novel-structure- ;provided Joy -inueni i n isafe cutt r- 1min: 19 f tsii by either the crease guide or the forepart guide :24 in a manner which is well understood in this art. One out into, but not through the sole is flush therewith. As shown in Fig. 3, the spur has the shape of a slim. wedge,- -its cutting edge being disposed at the right hand side of the feed- The operating characteristics of themachine will now be briefly summarized, but only .to the extent necessary for an understanding of the present invention.
The bottom rest IS-is adapted to seat upon the bottom of'ashoe S and hold the latter with the upper marginof thesole against the crease guide 22 or feed point 20, both of which extend intothe' welt crease of the shoe. The bottom rest l6 and feed-point 20 are oscillated together from-right'to left (when the machine is viewed from the front) to impart a feeding movement to the shoe, 5 and during the remainder of one cycle of operation are returned to their original positions at the right hand ends of their strokes.
The operation'of the continuously reciprocatin chopping knife is so timed that its cutting stroke, directed toward the feed point, terminates when the feed point is at the mid point of its return stroke. At this time the return stroke of the feed point-is momentarily interrupted, and'the' feed point is quickly reciprocated toward'and away" from the bottom rest so that the thrust of the knife upon the shoe, formerly taken by the crease guide, is resisted by the feed point whenthe sole is cut by the chopping knife. Thus, during each part of the return stroke of the feed point zo its sole engagingsurface is flush with or very slightly forward of that of the crease guidefwhereby back feeding action of the feed pointduring its return stroke is avoided.
In the above-mentioned Perry machine the chopping-knife, corresponding to the knife I8 disclosed herein, isso adjusted in the carrier that it just meets the feed point at the end of its cutting stroke. In the present machine on the'other-hand, the choppingknife I0 is so ad- 'justed'on the carrier l2 that its out extends well i 7 sole edge, is completed by making another out along the same outline directed from the upper margin of the sole toward the bottom thereof, these two outs being of such depth that each opens into the other. This cut or incision made into the upper margin of the sole is produced, in the operation of the illustrated machine, by the spur-32 which, as stated above, is disposed at the level of the knife. and also is offset slightly to the right of the knife so that any interference between'them is avoided. i
To summarize my improved method and the operation of the machine, the shoe S is presented to the machine in the usual way with its bottom resting upon the bottom rest l6, and with the crease guide 22 and feed point 20 extending into made by the rapidly reciprocating chopping knife Awhich makesa series of overlapping cuts, along the desired outline of the sole edge, extending point, facing toward the rightlinthadirection 7 of the return stroke of the feed point) .and at the level of the choppin knife l8. 1
fromrthe shoe bottom toward the upper margin of thelsole'. Each cutting stroke of the chopping knifeoccurs'between successive feeding strokes of the feed point and bottom rest, and also during the interruption in the return stroke of the feed point. A second cut in which the severance of the chip C from the shoe is completed, is made during each part of the return stroke of the feed point by thespur 32, this being a draw out in the upper margin of the sole, which, like each cut made by the chopping knife, extends along the desired outline of the rounded sole edge. The incision made by the spur 32 is also made slightly in advance of the path of the knife 19 and is of such depth that the cutting edge of the knife enters into it near the end of each cutting stroke. 7
Although the feed point does not bear upon the upper margin of the sole with any appreciable force during its return stroke, the solelmargin is substantially in engagement with the feed point at this time. Accordingly, the plate 34 is in such a position that it supports a limited length of the upper margin of the sole immediately adjacent tothe incision made by the spur, and thus insures against any deformation of the upper margin of the sole as a result of the cutting action of thespur. I
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
'1. That improvement in methods of rounding soles which consists in alternately making an incision in one side of a sole by a draw out extending along'the desired outline of the sole edge, and completing the severance of the sole by making another out along said outline directed from the other side of the sole into the incision;
2. That improvement in methods of rounding solesiwhich consists in 'making an incision in the upper margin of a sole along the desired outline-or theisole. edge, supporting a limited length ofithe said upper margin along each side of the said incision from the beginning thereof, andcompleting the severance of the sole by cuts directed from the bottom thereof into the said incision.
3. That improvement in methods of rounding soles whichconsists in making an incision in the upper. margin of a sole by a draw'cut directed along the desired outline of the sole edge, and completing, the cut through the'sole by a succession of chopping cutsextending from the bottom of the sole into the said incision.
