ROUNDING-MACHINE.

Specification of Letters Patent..

Application filed April 10, 1912. Serial No. 639,925.

To all tolto/n it may concern Be it known. that I, Anonsr R. SciIonNKY, a citizen of the 'United States, residing at Somerville, in the county of hliddlesex and State. of h'hresachuset-ts, have invented certain new and useful 1improvements in leunding-Machiues, of which the following is a specitieation, reference being had therein to the accompanying drawing.

My invention relates to machines :for roughly trimming or rounding the extending edges of boot or shoe soles prcliminzv rity tov the final sole stitching operation thereon. For example, in the manufacture of a welt. shoe the outsole is sometimes tem.- porarily attached to the insole, upper and welt. `while the upper is occupied by a wooden last, whereupon, before the stitching together thereof,-t.he trimming or round ing of the outward extension (consisting of loutsole and welt.) is to be performed.

An object of the present invention is to perfect the operation of such a rounding or trimming machine, and to include therein novel, functions Vtending to render the trimmed shoe in more perfect condition for the subsequent operation of stitching on a solc sewing machine, such for example as that referred to in my co-pending application Serial No. (380,356, tiled Feb. 27,'1912. Other objects and advantages will appear in the hereinafter following description or will be obvious tothose skilled in the art.

My invention contemplates .in a sole rounding machine in combination with the `rounding or trimming means or tool and the mechanism for operating it, a glittering knife or tool constructed and located to cut a shallow groovearound the top side of the extension (welt) above the outsole, near the edge. thereof, for the line of stitching to be subsequently applied.

My invention also consists in the further lcombinations, details and constrnctifm of parts hereinafter described and illustrated.

I will first describe one form of solo rounding machine embodying my unprovelnient, and will thereafter point out the novel features in the claims.

In the accompanying drawings forming a tion of the upper portion of a. machine embodyingmy improreimnt. Fig. Q is a lefthand 'elevation differing from Fig. l in that certain of the left-hand parts are removed to more clearly show the interior.`

Fig. il is a front elevation of a detail portion of the machine shown in Figs. l and 2 including tool for grooviug or guttering the top side of the extendingr welt. Fig. il: is a frontelevation of the machine and parts shown in Figs. l and Fig. 5 shows in cross-section a portion of a shoe on which are indicated operations adapted to be performed by the machine of Figs. 1 and 2.

Similar letters of reference designate corresponding parts in the several figures of the drawings.

The purposes of the present improvement may be partly explained by reference to Fig. o showing in crossseetion an incompart hereof, lFigure l is a 4left-hand elevaplete shoe and indicating Operations adapted to be performed by they machine hereof. The main purpose of a machine of the present type is to trim or round the extending sole and welt, and this ligure indicates the reciprocating trimming tool C which serves with each intermittent feed movement t0 trim oft a portion of the leather along the line indicated at a'. The shoe X is supposed to contain a' last during the preferred operation of the present machine. The shoe out.-

'sole and welt are clearly indicated in the tigure. [thas been found that in the. subsequent process of stitchin; v together the outsole and welt, it is extremely desirable that there should be formed in advance of the line 0f stitt-.hinga slight, groove or gutter in the welt, t his serving to receive. the lino of stitch ing, thusI not only facilitating the sewing operation, but improving the appearance of the shoe by avoiding extensive projection of the` stitches above the surface of the welt. The. formation of such glitter in the welt has not heretofore heen satisfactorily pertornud. and when done upon the sole sew.- ing uuu-bine, it has constituted an undesirable additional burden to the operation of that nun-hina intcrtcrirm with the accuracy and facility of the stitching operation.

I have conceived overcoming the .objection mentionedby the present invention of' a rough ,trimming or .rounding machine(A which serves to simultaneously trim the sole and to form the slight groove or gutter on the top sideof the welt, these two operations being performed by instrumentswhich act simultaneously' and in harmony so groove or cliannelfon the one hand and the outer edge ofthe sole on the .other hand is.

- secured. At g/ is indicated such a groove or A fore part ofthe shoe or else is to be limited gutter as may be formed in the top side of the welt by a machine embodying my invention. As will hereinafter more fully appear, it is not desired that sucliwelt gutter should extend entirely ,around the shoe, but on the contrary its forma tion is to be limited to the to that part of the shoe wherein the position of the trim 'line m is determined not from the crease of the shoe but by a guide bearing against the last within the shoe upper.

It will he noted -that a great advantage' lies in the formation of the groove y in the prese-nt machine .simultaneously with the trimming ofthe sole because this rough rounding machine is inherently one, .of heavy strong characteristics constructed for the heaviest kind of work vand is well able to take up and to form both etiiciently and accurately the making of the welt groove y, whereas the lighter and more delicate'sole sewing machine Awith vits coperatiug aivl and needleis thereby relieved' of a burden for which it is not well adapted. Y

It should bementioned that where it isl desired to form a lip on the outsole opposite to the welt. groove 1/ for the reception and concealment' of the lower connecting stitches, that can be done on the present machine as indicated at e.

Thus the present machine is capable of performing the three operations indicated.

hy thecuts at ai, 1/ and le, fully' preparing the shoe for the succeeding operation of sole sewing. v

From the above it will be seen that I-have devised not only a new machine, but a new mode of procedure, and Ibelieve that I am the first t'o propose the method of manufac# turing a` welt shoe comprising the step of preparing it. for the sole sewing operation, which ste consists in rounding the sole with a trimming tool and simultaneously, as the rounding progress in producing a gutter around the welt in a. given relation to the trimmed edge. This method more specifically considered comprises the featuresthat'the glittering of the welt takes place only around the fore part'. of the shoe, that suoli guttering takes placeonly while Athe shoe is being guided from its last` and that inta'ddition tofthetrimmingnand the weltY that an-l .exact4 predetermined relationbetween the '10.

.deep groove 'by which holds the shoe, or

lip formed. vby cutting the deep channel aroundtlie bottom edge of the sole simultaneously with the other operations. N

Y"Hereinafter I refer tothe toolaoting on the welt as a gtittering toolA since it de- .presses or cuts a -mere gutter `or shallow groove for the stitches to` lie in; Whereas the knife acting'on the lower sideof the solf.; it a channeling tool since produces a cutting as indicated toform a lip Ywhich may be opened .out duringl or before stitchingg. and thereafter .closed to i conceal and protect the stitches. The former tool `vis a Welt guttering tool, the latter an .outsole channeling orl lip-cutting tool.

In` order'.to Afacilitate understanding the 4following detailed description ot mechanism I will here statethe order of.description,

which. will be as follows. First, Itivill describe a clamping or supporting means bears during the trimming and other operal tions. Second, I will desciibethe tool and operating mechanism for feeding and progressively trimming or rough rounding the sole or extension, including th extending welt, Third, I Wi-ll describel the guiding means which determines the line` of trimming, which will be seen to comprise a 'crease guideanda last guide with atreadle Afor throwing one or the .other into or out of againsit which it` ment and no limitation. thereto is intended excepting as stated in the appended claims.

Indeed in some cases the type andi details will be understood by those skilled in the art, so that at times a general rather than a specific description may be hereinafter employed.

A convenient clamping or supporting means against which the shoe may bear during trimming is as follows: General portions "of the machineframe are" shown, for example, while A and A2 hand and right-hand overhanging arms which su port the shafts and certain other parts.- ther special frame portions will be indicated hereinafter by the references a, a', etc. It will beunderstood that the machine may have a downwardly extendindica te the left-l Losanna iiigvsupporting post a, which is only partly shown, but which would ordinarily extend to the floor where it may be suitably secured and where it may be provided with seen, is opposed by guide and feed members hereinafter to be referred to. The portion I) of the support B against which the sole actually contacts, is a rotating roll mounted on a central pin, which at its upper end is connected to a plate n', and at its lower eiid to a collar b2, both ot' which are carried upon the uprightbar b3,'which in turn is Vcarried at tlie for 'ard' end Zi of a longhorizontal slide bar 44 suitably sngjiported in tbe frame of the machine, so as to be capable of sliding ,backward and forward. The slide bar b4 has a strong spring b which is adjustable as to its compression by a screw 5; said spring tending to yieldingly maintain the support B in the forward position indi-- cated in the drawings, there being a suitable stop to determine such forward position.

To open up the parts for the reception of a shoe at the beginning of an operation, the upright bar l1 and horizontal slide b are pushed backwardly through a lug bl, Fig. i, formed upon portion b, and contacted by a. lug 's upon an arm 7) extending froml a short shaftl 51, whose inter end is profvided with a forwardly extending arm Zi, by which the shaft may be oscillated for throwing the army and lugs to move back the support B, thereby enabling the operator to insert the extending` solo and welt of theshoe r between the support B and the opposing parts. The arm bu may be depressed by a chain and treadle or otherwise.

A convenient trimming or rough rounding tool and operating mechanism may bc as follows: I prefer a reciprocating form of tool C adapted to make successive cuts through the sole .and welt as the latter are caused to advance under the guidance of suitable guides. Opposed to the trininiinmiool C is 'shown a member l), which mayser'vc as an anvil against which the blows of the tool C are received. and may serve also as a supporting member cooperating with the sup port B, the work passing between them, and may 'serve also as one of the elements of the -feeding mechanism for causing a step-bystep advance of the worlt.

i To properly guide the trimming tool C in its reciprocating movements, it is shown ,Zontal shaft W.

mounted upon a heavy arm c extending upwardly to where at its upper end it has a hub or sleeve loosely mounted on the horitlie main orpower shaft 1V an eccentric c indicatediin dotted lines, engaged by an eccentric strap 02,'liaving a projecting arm c pivotally connected to the heavy arin c already mentioned. By vthis arrangement the rotation of the main shaft W causes the trimming tools reciprocatioii.

Any convenient means for feeding the work forwardly may b'e employed. For example, the member l) already mentioned may cooperate with the support B for this purpose. The member l) is seen at the lower rnd of a vertical bar d, which is secured by For reciprocating the trimming knife C, I prefer to mount upoir bolts d', d or the like to an arm Z2 extending from a. sleeve or hub d surrounding the shaft Vif', see Fig. 4. 'Py any convenient means which will not be further described, the hub d may be controlled to vibrate lengthwise of the shaft and alsohto oscillate about the shaft. By suitably proportioning the cams which effect this the memberl) may be given any desired movement within a small compass. For example, when the work is clamped between thsupport B and the member l), the latter 'may move bodily to the operatos left, thus feeding the work to the left, and may then swing out of contact with the work and back to the right again, rengaging the work but in a new position preparatory to a succeeding movenient to the left. The support B being ro-l tary readily permits this stcp-by-step feeding. During the back movements of the member D the work is held by the support B cooperating with a guide E hereinafter to be referred to. By this arrangement the work is intermittently fed forward, for example, a quarter inch at a stroke, and the trimming knife C at each stroke chops or cuts to that extent progressively around the extending solo of the shoe.

1 will now describe convenient., guiding means appropriate for an embodiment of my invention. Preferably the guidingr means will include two separate guides E and l". As shown herein, the guide E is a crease guide, while the guide 1* is a last guide intended to bear against the lastor form contained in the shoe. The guide E is shown as a shank-guide intended to be replaced around the tore part of the shoe lby the guide F. f

Referring first to the details of the crease ibo guide E, this will be seen to be a U-sbaped i member, its central opening serving to accommodate the member l) already referred to. The guide E is supported from an arm e, being secured thereto by attaching screws e. The arm e extends rearwardly to where it is mounted at el to oscillate aboutie xed axis. A spring c3 to press the latter'upwardly so as to yieldingly maintain it in the position shown, a. portion ot it at e4 bearing against the coi ner al* of the arm cl2, which acts as ya stop.

Ordinarily while the shoe is being guided b y the engagement of guide E in the crease rated position in a yielding manner by 'means oi? a supporting yarm f turning on short shaft f and acted upon by spring f2 arranged for convenience to surround the shaft f. rl'he guide F is shown connected at the frontend of the arm f through a plate beneaththe arm e tends f3, which extends from the arm to theV right shown in Fig. et, and a movable arm f* pivoted at f5 to plate f3 and extending downwardly to where at its lower end it car-v ries the guide F. A spring f bears upon the pivoted arm Jf4 tending to holdit in the normal position shown, but permitting it to yield forwardly when its guiding operations so require.

For causing the descent of the last guide F from the inoperative position of Fig. l to the guiding position of Fig. t2, rny convenient means may be employed, saclrfor example as the chain f7 extending from the arm f downwardly to a treadle or the like, which upon being depressed at the operators will brings the last guide into play so that thel shoe will ybe guided :trom the last instead of from the crease. For limiting the descent of' thc last. guide a stop f8 may be employed connected by a triangular extension f from the.I guide carrying arm f, the stop f8 being so located and constructed as to cooperate with a hub or collar flo surrounding theA shaft YV by contacting with the same as seen in Fig. Q, when the lastguide is in proper operative position.

l have. thus described a duplex guiding means comprising the crease guide E which normally guides the shoe from the crease,

and the shift able last guide which may be` brought into play to force the shoe slightly farther down, and so shaped as to guide the shoe from the last rather than the crease. lt will he understood that in certain types of shoes it is desirable in trimming the sole along the shank part to guide the work from the crease and to thereafter change the manner oi' guiding so that in trimming around the fore part of the shoe the extent of projecting sole 'is 'determined no Ilonger .trom the crease'but from the last or fori-n ot the shoe. i

l. will now describe a means for guttering the top side ci" the extension, thatuis to say the welt of the shoe, automatically and simultaneously with the progressive trimming lot the sole edge. lt will be under- 'stood that while the extending edge is being trimmed the work fis clamped or supported between the rotatable support B on the one-hand and the member D and guide E opposed thereto, while the trimming knife C recipiocates. The bottomlof the outsole lies toward vthe support B, while the top side of the welt 1s contacting with and held -by members l) and, li now' in such a combination oi parts we piace' between or approximate to the members D and E a glittering tool G adapted tobe made to eX- tend into the path of the work, as seen in Fig. 2, it will simultaneously 'with the trimming operation and as the-latter progresses score' or depress or cut in `the top side of the Welt a gutter or shallow groove, whose po- `sition`relatively to the trimmed edge or other part of the shoe will be. accurately determined, for example by locating the tool G in a fixed' relation to the trimming knife C. Such an arrangement is here indicated, and we therefore have a machine whic.. simultaneously'and progressively both trims the sole edge and gutters the top of the welt near its edge.

I prefer that the guttering tool G. shall not always be in cutting position as shown in Fig. Q, but shall be shiftable from cutting position tothe noncutting position indieated in Fig. 1. A convenient mode of permitting this shitting is to constructthe gut-tering tool or knife of a piece of flexible metal of substantial length. rlhus the tool G is shown as consisting of a generally Y-shaped piece ot metal when seen from the iii-ont, and its upper branches are secured as by screws g to the side portions et the U-shaped crease guide The. glittering 11 iii.

tool by this arrangement is not only aorded jV support but is renderedable to shift.

lt is desirable that a gutter shall be cut around the welt only at the fore part of the shoe, and I have shown means for automatically eiiecting the shifting of the tool Gr into active position when passing around the tore part of the shoe, and out of active position when the shoe shank is being trimmed. This is accomplished in the present einbodiment of my invention by a device moving with the guide F and acting upon the `guttering tool lo throw the latter into cutn tingposition when the guide F is brought into guiding position. Thus whenever the operator guides the slice by the last, he depresses a treadle to force the iastguide F downwardly'from the position of Fig. l to the position of Fig. 2. Mounted upon' eachV side of-the last guideis 4a properly positioned roller g', whichupon the descent of the guide F comesinto contact 4with a projectiony or curved portion` of the' tool G,

' that isfaccomplished,bylallowing the guide F andthe arm' carrying it to rise, thus permitting the glittering tool to return to inx operative position as shown in Fig. 1. Byf` this arrangement the `treadl'e chain f1'eonstitutes @controlling means for alternately or intermittently putting the respective guides, into operation, and for also auto matic-ally putting the guttering or grooving tool Gr into andoutof action.

Referring to Fig. 5, the work of the trimming knife C. is indicated by-the line of trimming or cutting, while the work of the welt gutteringrtool Gr is indicated by the shallow. groove or gutter y on the top side of the weltbetween the trim line :n and shoeof the outsole by` eutting'a deep grooveor tom of the outsole.

channel, I have indicated a channel or lip cutting knife H, which is mounted for conyenience at the front end of the plate b already mentioned, beneath which the rotatable support B islocated. It will be seen from Figs. 1 and 2 .that the knife H is so shaped and located as to form a deep slanting-cut, producing a decided lip in (the, bot-- X This cut and lip are clearly indicated at z in Fig. 5, the lip being such as to enable it vto be widelyopened during or before a subsequent stitching operation,and then closed for the protection of the stitches. The relative position of the lip. forming knife H and the trimming knife C determines lthe distance. of the channel from the edge. As the distance of the gutter y from the edge is also determined rby the relative position of the guttering tool G and the trimming knife C, it is easily arranged that the gutter y shallbe produced directly opposite the extremity 4 of the cut z as shown in Fig. 5, which is the preferred arrangenient.` VIn this way the guttering knife (if `eooperates not only with the trimming tool but with the lip forming knife.

As an auxiliary expedient, though not per se forming any part of the present improve-l ment, I Ywill mention the adaptability of the lip forming knife H to shift slightly `relatively to the trimming knife. Thus in Fig.'2 the knife H is a certain distance beneath the l nife,C, while the shoe is being guided by the Alast guide F, and at thesame time the glittering tool G is in operation.

engagement with link bw. By

This is the operation around, the fore part of4 theshoe. Suppose it be desired on passing 4from the fore part of the shoe to the shank to displace thelip to a position nism is indicated for accomplishing this as follows.` blz indicates a swinging arm turning about an axis or shaft bi, mounted in the forward part'b* of the horizontal slide slightly farther from the shoe edge, mechaalready mentioned. The vertical bar 3 falready mentioned, may be fitted to slide verti.c'ally, inclosed between the two sides of part b1, and its movement may be effected b an interior connection such as a rack and pinion, so that by swinging the arm 612 the support B and of the lipforming knife H may be determined. The rear end of swinging armwb12 is connected with the arm f which swings the vlast guide F. This con` nection consists of a link b15having a ball and socket connection above and below, and a spring' b1 holding the arm 612 up in secure such an arrangement the lifting of the last guide F upwardly from the position of Fig. 2 to the position of Fig. l, permits 'the upward move,-` mentof' link b1 and thereby of swinging arm b1, the forward c nd of which causes a slight depression of bar b3 and lip forming. knife H to their position show n in Fig. 1.

The operation of themachine hereof will be well enough understood from the above description of the mechanism. Such operation consists essentially of a simultaneous ,progressive sole trimming, welt guttering and lip forming around the fore part of the shove or when guided from the last, and a 4simultaneous sole trimming and lip forming IWhat I claim and desire kto 'secure by Lctl terslatent is:
