'wmrltleediug devices arranged to operate upon opposite sid is of the Work, and having uorlooug sing surfaces constructed and arranged to all'ord only restricted areas of con avith lat portions ot the work, and. a carrier for one oi: said devices mounted for tiltinc; adjustment about an axis located at a point remote from the work but substantially in. the plane of the Work e;, in the. plane or path oi: that portion of the work which is heiu operated upon by the Work feeding dctires), and extendin in the direction of work teed. As illustrated, the Work feeding members have convex or bulging peripherim-i adopted to aiii'ord only restricted areas oi contact with hat portions of the sole margins, and the 'lfeoding members are further so crmstrueled and. arranged that by mounting the carrier for the tiltable member in the ah:iredescribed manner the areas of contact oi? the members With the opposite sides oi the work will hear substantially the same relation to each. other transversely of the vide means tor openin der the influence oi the feed members Will be the same, ll'lGrSPGClIlVQ of variations in the thickness of the Work. Furthernun'e, the illustrated Work-feeding member is rendered extremely sensitive to variations in the thickness oi? thewvork and. is capable of moving toward or from the cooperating teed member so as to adjust itselt freely to avoid the possibility oi? unduly compressing the sole man gin. and thereby injuring; or detaciug it in any way or interfering With the manual guiding oil the Worlt.

In accordance with a tiurther feature oi the invention. the illustrated machine conipriscs a pivotally mounted carrier in Which. is jourualed a shaft carrying; a lower :lieed roll, a driven pulley carriedhy said shaft, u drivingpulley, and a belt connecting; said. pulleys, the driven pulley being so lot-aired, relatively to the pivotal axis of ti e carrier, that the distance between the pulleys "will remain suhstantially constant irrespective of changes in. the tilting adjustment oi the carrier.

Another object of the invention is to prothe channel and. raising the lip into position to be acted upon by the lip-turning Wl'ieol, so constructed. and :urrauged that it will be capable of following the curves or bonds in the channel of a molded sole without danger 0t leaving the channel or ulululy distorting the channel lip.

\Vil'h this object in View, the illustrated u'iachine is providedWith a channel opening device or plow which is mounted tor-tilting adjustment about an. axis tra'uswrsc to the direction ot wort; feed and suibstautially parallel to the plane oi. the work. As shown the plow not only capable oi? tilting adjustment as above descriheifl but is also capable oi ZllljllE-lidllttill} in the direction of its pivotal. axis in eecrudance withthc Width of the channel. in the sole to be operated upon. I

The invention further consists in jl1)l1)10\*- merits in the. mounting; of the upper teed meluhi-ur and the lip-turninp member, in improved means for drivi'itig said members, and in various details of constraction and arrangonients oi? parts hereinafter described and claimed.

The invention will best be understood by reference to the following description of the preferred embodiment thereof illustrated in the accompanying drawings, in which:

Fig. 1 is a view, partially in side elevation.

and partially in section, of a machine constructed in accordance with the present invention;

Fig. 2 is a detail view, partially in plan and partially in section, on the line 22 of Fig. 1, showing particularly the relation of the operating instrumentalities to the work;

Fig. 3 is a perspective view illustrating the operation of the lip-turning wheel, the

lipraising plow-and the presser foot;

Flg. 4 1s a detail sectional view through c the operating instrumentalities of the ma- 10, an upper feed member or disk 12 and a lip-turning member or wheel 14. \Vhile these instrumentalities operate to feed the Work and turn back the channel lip in substantially the same manner as corresponding devices in the copending application above referred to, various improvements relating tothe construction, mounting and driving thereof have been embodied in the illustratedmachine, as will now be described.

The work-feeding and lip-turning devices above-mentioned are supportedby a frame l6which is made in the form of a housing shaped to enclose the driving mechanism and adapted to be mounted upon a work bench'or other support. J ournaled within bearings 18and 20 formed within theupper portion of the frame or housing 16 is a horizontal main shaft 22. As shown in Fig. l, a longitudinal tongue-and-groove driving connection 24 is provided between the main shaft .22and a driving shaft 26 which is coaxial with the main shaft 22 and is journaled at its inner end within the bearing 20 and at its outer end in a bearing formed in a bracket 28 detachably secured to the rear of the frame 16. The driving shaft 26 carries a pulley 30 adapted to be connected by a belt 32 with any suitable source ofpower. The tongue-arid-groove connection 24: en ables the shaft 26 readily to be disconnected from the shaft 22 by removing the bracket 28, and the shaft 26 and the bracket 28 may be replaced by an electric motor having a motor shaft provided at one end with a tongue adapted to enter the groove in the main shaft 22 to establish driving connection with'the motor.

The lower feed roll it) is carried by a shaft 4.6 which is journaled in a pivotallv mounted carrier 48 and has secured thereto the belt pulley 50. The lower feed roll l0 and the upper feed disk 12 are driven at substantially the same radial speed by means of a single belt 52 which passes over both the pulleys ll and 50, and over an idle pulley 54- and a, driving pulley 56. The driving pulley 56 is secured to a horizontal pulley shaft 58 which is connected with the main shaft 22 by means of intermeshing worm gearing 60. The idle pulley at is carried by a bracket 62 pivoted at (it to the. frame 16 so that it may be adjusted to take up the. slack in the belt :32. The bracket 62 is sccured. in adjusted position by means of a. bolt 65 which extends through an areuate slot in the bracket.

The lower feed roll 10 is of the shape of a. conoidal frustum having convex or bulging sides (see Fig. and comprises an annular member 66 which encircles the sha ft 46 and is clamped between a collar 67 fast on said shaft and a nut 68 which is threaded upon the outer end of the shaft. The annular member 66 is so located that its periphery engages the lower side of the work at a point opposite the point of engagement of the upper feed disk with the work and the periphery of the member 66 is roughened or knurled to increase its tractive eliect upon the work without causing it to mar the work. The carrier 48 for the feed roll 10 comprises a bearing portion, in which the shaft it; is journaled, and a yoke portion 70 the arms of which carry trunnions 72 which are mounted to turn in bearings in the side walls of the frame 16, thus providing for free up and down tilting adjustment of the lower feed. roll 10. The axis of the trunnions 72 is located substantially in the plane or path of the work, or that portion of the work which is being operated upon by the feed members and the lip turning wheel, so that the tilting adjustment of the lower feed roll will not effect any substantial change in the illustrated co-operative relation of the re stricted areas of contact of the feed members with the work. The carrier 4-8 extends through an aperture 49 in the front of the frame 16 and is positioned with the shaft 46 lncllned as shown in Fig. 1 so that the conoilllii lltl dal periphery of the lower feed roll will support flat portions of the work in a substantially horizontal plane. The shaft 46 extends downwardly beyond the bearing portion of the carrier 48 to receive the pulley 50 and is formed with a pair of depending ears 74; between which is pivoted the upper end of a rod 76 the lower end of which is guided for up-and-down movement in a bearing 78. The rod 7 6 is adapted to be connected with a foot treadle (not shown) by means of which the lower feed roll 10 may be lowered to facilitate the introduction of the work between the feed members. A. spring- 8O surrounds the rod 76, between the bearing 78 and a collar 82 upon the rod, and urges the feed roll 10 upwardly into yielding engagement with the work. The collar 82 backed up by nuts 84; which may be turned to vary the tension of the spring 80. Upward movement of the feed roll 10 under the influence of the spring 80 limited by engagement of an abutment 86 formed on the carrier 48 with a stop screw 88 carried by the iran'ie, while down ard movement oil. the feed roll 10 is limited by means of a stop screw 90 arranged to engage with the ears T l. A lock nut 92 on the sto p screw 88 provides means for securing the latter in adjusted position. The axis of tilting adfur ment of the lower feed roll extends substantially at right angles to the axis of the driven pulley 50 an d is located sul)stantially midway between the positions assumed by the lower stretch of the belt 52 at the opposite limits ot adjustment of the lower teed roll. In. other words, the axis about which the lower feed roll may be adjusted is located substantially centrally of the held of displacement of the belt 52 resulting :lirom tilting}; adjustment oi the carrier 48 and the lower iieed roll. Consequently, such adj ustnient oil the feed roll will not appreciably tighten or loosen the belt. It will be apparei'it ill'OUl an examii'iation of Fig. 1 that the lower teed roll so shaped and the axis oi the lower feed roll carrier is so located that said roll will engage the work throughout an area oi substantially the same extent and location relatively to the sole edge and relatively to the point of contact Oil the upper l'eed disk with the work. irrespective oi? up or down moven'ient oil? said roll due to variations in. the thickness of the sole being operated upon. Thus the action of the work under the influence oi? the feed members will be the same irrespective oi? variations in the thickness of the work. By making the lower iced. roll. in the form shown, this roll is par timilarly adapted for feeding those portions oil a sole margin which are list, since a restricted area of feeding contact is obtained which has been 'liound to be sufiicient to insure positive feeding of the sole without interfering with the manual guiding or swing ing of the sole as the lip -turning operation progresses around the margin thereof. Further, the bulging oi? the periphery of the lower feed roll enables the roll to conform substantially to the transverse curvature along the shank portions of a molded sole so as to avoid flattening out this part of the sole. On account oi? thesinall diameter of the lower feed roll the roll. will pass over the abrupt bend at the junction of the shank and forepart of a molded sole oil? the cottage shank type without flattening out the bend and the roll has no tendency to distort or break down the molded contour of any part of a molded sole.

As best shown in .hlig. 4;. the upper teed. disk 12 has a slightly bulging lower :l'ace adapted to engage the upper side oi? the feather of the sole at a point directly above the annular member 66 of the lower feed roll. The upper portion of: the upper teed disk 12 is of truncated conical. term and is normally contained within a similarly shaped. recess in the lijrturning wheel ll. The feed disk 12 is provided with a smooth pe riphery adapted. to engage the base oil [he turned channel lip to assist in. guiding the sole. The teed disk is threadedly connected with the reduced lower extremity of the shaft 4-2.

The shaft 42 carrying the upper ieeddisk i2 is journaled at its upper end within a bearing 96 lorn'ied within a housing member 98 detachably secured to the front oi? the frame 16, while the lower portion oil the shaft 49, is journaled within the sections 38 and ll) of the sleeve which carries the lip turning,- wheel. The pulley it, carried by the shaft 42, is located between upper and lower ball thrust bearings 100 and 101, which prevent endwise displacement of the shalt.

The lip-turninpwheel fl l is shaped as shown in Figs. 2, 3 and it, and is provided with tour equally spaced apart projecting arms each having upon. its under side an. upwardly and. outwardly curved work-engaging surface adapted to wipe across the inner face at the channel lip as the wheel i l: rotates so as to turn the lip baclcward and lay it down against the upper face oi" the sole. A central conical recess or socket 91 forniedin the lower side of the lip-turning wheel. to receive the upper teed disk 12.

The lower section it) of the lipturuinn wheel shaft is journaled in a suitable bushing 1.02 which is threaded at its lower end within abearing 104: formed in the lower portion oi? the housing 98. The lip-turning wheel shaft is supported in the bearing 104: by means o'lt an annular flange lilo which is formed at the upper extremity oil? the lower shaft section 4:0 and rests upon a ball bearing 108 which is interposed between the bearing lO l and the flange 106. The upper section. 38 oi the lip-turning wheel shalt is as they are yieldingly pressed into feeding against said gear and at its lower mounted to turn freely upon the shaft 42 and inasmuch as the gear 36 is iiast upon this shaft section, the latter is prevented from being axially displaced by engagement of the gear 36 with the bearing 101 and with the gear 34. The upper and lower sections of the lip-turning wheel shaft are coupled together to turn in unison by means which permits the lower shaft section to move longitudinally relatively to the upper shaft sectionso that the lipturning wheel may yield relatively to the upper teed disk in accordance with variations in the thickness of the portion of the lip which is being engaged by the lip-turning wheel. This coupling means comprises two tongues which depend from the upper shait section at diametrically opposite points and are slidably received in similarly disposed eripheral notches in the flange 106. A spring 112 encircles a hub 111 depending from the gear 36, the spring hearing at its upper end end against the' flange 106. The force of the spring 112 tends to hold the lll ktllllling wheel yieldingly in a lowcr position deter-- mined by engagement the flange 106 with the bearing 108, but permits the lip-turning Wheel to yield upwardly relatively to the upper feed disk as may be necessary to accommodate variations in the thickness of the lip. To hold the upper ball race of the bearing 108-.in hall-retaining position as the lip-turning wheel and the .tiange 106 yield upwardly, a spring 11.0 is seated in a socket ol the flange 106 and arranged to press downwardly upon the upper ball race of said hearing. The lowermost position of the lip-turning roll 1 1 is determined by engagement of the ball. bearing 103 with. the upperend ot the bushing 102. The lower end of the bushing 102 projects below the bearing 10st and is notched as shown at 103 to receive a suitable tool by which it may be turned to raise or lowerit in the bearing 104 and thus to vary the lower the lip-turning wheel. A lock nut 105 is provided to secure the bushing 102 in ad- I on account of the slight transverse bulge in the periphery of the lower teed roll 10 and the convex or rounded contour of the lower face of the upper feed disk 12 these usted position.

.members are, enabled to embed themselves to a. very slight extent in the sole material engagement therewith and thus they are caused to grip the sole so as to resist edgewise movement of the sole away from the edge gage. It is desirable that the sole shall be continuously urged toward the edge gage while it is being fed so as to render it unnecessary for the operator to exert constant pressure against the sole while it is being operated upon. 0 To this end the lower feed position of roll is pivotally mounted, as above described, in such a manner that it will more upwardly and rearwardly under the force of the spring 80 and will thus exert an inllucncc tending to cause the sole to hug the edge gage. Furthermore, the larger end of the lower teed roll is arranged to engage the sole at a point nearer the sole edge than the smaller end of said feed roll and as a result the roll will tend to swing the sole toward the edge gage on account of the greater lineal spccd ot the feeding surface at the larger end ol? the feed roll. The tendency of the sole to hug the edge gage is further facilitated by the mounting oi the upper teed disk with its axis inclined to the horizontal. at th angle shown in the drawings. The inclination oi the axis of the upper feed disk and the similar inclination of the axis of tho lip-turning wheel enables the operator more easily to watch the progress of the lip-turning operation.

To locate the channel lip transversely relatively to the lip-turning wheel, an edge is provided. The edge ga go 120 is in the form of a roller which is pivolally mounted upon a carrier 122 having a horizontal shank 124 which is received in a socket formed in a bracket or cross-bar .120 which bridges the aperture 40 and removably secured to the frame. The shank 12 i of the edge gage carrier extends horizontally at right angles to the direction of lord and is rigidly secured within its socket by means of a clamp screw 128 which may be loosened to permit adjustment of the edge gage in accordance with the width ol the feather and the lip of the sole.

Before the lip is acted. upon by the lipturning wheel, a preliminary clnuinel-opening or lip-raising operation is pertlbrined by means of a plow 130, best shown in Fig. 3, which is located finrwardly oi the lip turning wheel and is arranged to enter the channel and to raise the lip to a position just above the plane of the lip-turning wheel so that the lip may be properly engaged and acted upon by the wheel.

The plow 130 formed with a pointed tip shaped to enter the channel and raise the lip as the sole is fed. The plow is mounted for free lateral tilting movement about an axis perpendicular to the direction ol feed of the sole and in addition the plow is adjustable transversely of the direction 01 work feed in accordance with the width of the channel in the particular run of soles being operated upon. To this end the plow is fixedly secured to the outer extremity of" a trunnion 132 which is mounted with provision for axial adjustment in ball bearings carried by the bracket 120. 'As shown the ball bearings comprise inner ball races 13!- and 136 rigidly secured to the trunnion 132 and outer ball races 138 and 140 which are Ill] llii

slidable axially within a cylindrical bore M2 in the bracket the bracket 126 is split as shown at i ll in such a way that it may be contracted to clamp the outer ball race to secure the plow in adjusted position transversely with respect to the channel. A. binding screw 1&6 is provided for contracting the bracket 3. 6 so as to clamp the ball race 138. The plow is curved as shown in l ig. 3 to avoid interference with the lip-turning wheel 14; and the point of the plow while located as close to the lipturning wheel as practicable is llQVQillllGlQSS oit'set forwardly from the axis or the trunnion 132 about which the plow is tree to tilt. gonsetpiently as the plow tilts in following the up or down curves in the channel of a molded sole the point of the plow will be raised or lowered as the case may be to insure that it will remain within the channel.

immediately after being acted. upon by the lip-turning roll, the bt-ickwardly turned lip passes beneath a guide linger 150 which assists in setting the lip and prevents the solo from being tilted by the operator so as to cause any portion of the sole to be injured by the rapidly rotating lipturning wheel. The guide finger 150, best shown in Fig. 3, is arranged to project transversely across the channel lip and is provided with a cylindrical shank. portion 152 which is rigidly secured in a socket in the bracket 126 by means of a clamp screw 154:. The screw 154; may be loosened to permit adjustment oi? the guide linger transversely with respect to the direction of work feed.

inasmuch as the edge gage, the plow 130 and the guide linger 150 are all mounted upon the removable bracket 1%, they may be conveniently assembled before the bracket secured in place, and the bracket may be renamed at any time to render the parts mounted thereon more conveniently accessible for adji'lstment.

The machine, as herein described, is of topic and rugged construction. 'lhe mechanism of the machine is compactly arranged. and, with the exception of the instrumentalities which engage the work, is enclosed within a casing which protects the mechanism tron: injury and from accumulations of lint and dust. l urtherinore, the construction and arrzmgcment oi? the driving mechanisziin such that the machine is capable of operating a t high speed substantially without objectionable vibration and noise.
