Application filed February 28, 1922'. Serial in). 540,037;

The present inventionrelates to channel flap turning machines. and is herein illustrated as embodied in a machine for turning back thechannel flaps of soles for McKay shoes; Certain features of the invention, however, are adapted for embodiment in machines for operating upon other kindsof soles. J

In the manufacture of boots and shoes of the McKay type in which the soles are united to the uppers or Vamps by fastenings inserted from theouter finished surface of the sole, it is customary to use channeled soles, a flap being formed inchanneling, which flap is turned over backwards and pressed down, so as to leave the channel open for the reception of the fastenings, the flap being turned back again to its original position after the sole and vamp are united.

In order to facilitate the operation ofsecuring the sole to the shoe it is desirable to have the channel flap turned and set. in a substantially flat position closely adjacent to the face of the sole to insure that the flap will not interfere with the action of the needle in the McKay sewing'rnachine, and it is further desirable that the required turning and setting of the lip shall be ac complished without frictional rubbing of' the sole margin such as would tendto. burn or otherwise injure it. 7

One object of the present invention is to provide a channel flap turning machine having an improved construction and mode of operation enabling it to accomplish the results above set forth.

With this object in view one'feature of the invention consists in the provision of a channel flap turning machine havinga rotaryw orlr feeding member, an independently mounted flap turning member arranged to rotate in a plane'parallel to the plane of rotation of the feeding member, and means for rotating the flap turning member at a higher speed than the work feeding member. As shown, the rotary work feeding member consists of an upper feed disk arranged so that its lower side face will engage the upper surface of the feather or marginal portion beneath the channel flap of a sole, and this disk is mounted in coaxial relation with the flap turning memher and is arranged to co-operate with a lowerfeed Wheel to grip and feed themargin of the sole. By providing separate members for turning the channel flap and for co-operating with the lower feed wheel in the feeding of the work, the flap turning member may be constructedand arranged so that it will engage the channel flap only, and so that it may be rotated at a much higher speed than would be practicable if it were designed also to have feeding engagement with the sole margin. The relatively high speed of the flap turning member enables the latter more effectively to turnthe channel flap over, against the face of the sole and to set the'flap in a substair tially flat position while the relatively slow speed of the upper feed disk insures against injurious rubbing contact with the sole margin.

Other features of the invention relate to the yielding mounting of the flap turning member, and to the provision in this memberof a recess to receive the upper feed member'to'facilitate operation upon soles having thin channel flaps.

The invention further resides in other features of construction and combinations machine Fig. 2 is a view in front elevationthereof;

' Fig. 3 is'an enlarged sectional detail of the head of themachine; 1 4 is a sectional plan viewon the line 4r--4 of Fig. 1, and Fig. 5 is a sectional of Fig. 4:.

Referring to the drawings designates a base having formed integral therewith an upwardly extending portion 11 in which is rotatably mounted a horizontal shaft 12 provided at one end with a pulley 13,.by means of" which power may be transmitted to the shaft from any suitable source of power and at the other end with abevel gear 14.

detail on the line 55 A bearing member 15, formed integral with the portion 11 and atthe top thereof, is provided with a sleeve or bushing 16,.this sleeve described. Near the lower end of the portion 11 is a second bearing men'iber 20, in which is rotatably mounted the lower end ofa hollow shaft 21, the upper end of this shaft terminatin at a point below the lower: end of the sleeve or bushing 16 and being rotatably mounted in a. sleeve 22 threaded into and adjustable in a bearing member 23 secured to the portion 11 by a bolt 24. Secured to the hollow shaft- 21 by a set screw 25 is a bevel 26 which meshe with and is driven by the oevel lei on the driving shaft 12. A coil spring 2'? surrounding the hollow shaft 21 and located between the upper end of the bevel gear 26 and thebo tom of the threaded sleeve 22, hole s the bevel gears 26 and 14: in engagement vith each other. The sprin 27 also functions to cushion the turning roll 6 1, permitting it to yield upwardly relatively to the disk 63 to accommodate dilferent thicknesses of channel flap *ithout requiring readjustment of the parts. Rotatably mounted in the sleeve or bushing 16 and the hollow shaft 21 is a shaft 28 limited in its downward motion by a bushing 29 secured to the shaft by a set screw 30, while a bevel gear 31 is secured to the shaft, adjacent the portion 15, by a set screw Further, the bolt 18 engages the top of the shaft 28 to limit its upward movement. The bevel gear 31 meshes with a bevel 1 Iral which is rotatably to a sham o mom d in the portion 11. parallel to the shaft 12. A table bearing on the portion 11 supports the end of the shaft- 34 at the end remote from the bevel gear 38, and secured to the shaft 3 1- is a worm wheel (not shown) which meshes with and is driven by a worm 36 secured to the top of a shaft which rotatably mounted in bearings 38, 39 and ll) formed integral with the portion 11. Secured to the shaft 37, adjacent to the bearing 39, is a worm wheel. 11 driven by a worm (not shown) secured to the drive shaft 12. The lower end of the shaft 37 extends downward below the portion 11, as clearly shown in Fi 1, and has attached at its lower end a worm 42 which meshes with a worm wheel 18 secured to a shaft 14 mounted in a bearing 45 formed integral with the base 10, a collar l6 secured to the shaft by a set screw 17 preventing inward movement of the shaft. This shaft 4A is located at an angle with regard to the shaft 37 and is connected to a shaft 48 by a universal joint 49,

the shaft 48 being rotatably mounted in a bearing 50 slidably mounted in a frame member 53 that in turn is secured, by bolts 52, to a lug 7 2 that is adjustably mounted on portion 11. Formed integral with and at the lower end of the frame member 53 is an outstanding lug 54 in which is slidably mounted a bolt 55, the upper end of which is threaded into the bearing member 50 while to the lower end of which is attached the eye 56. Check nuts 57 on the upper end of the bolt are utilized to adjust the tension of a coil spring 58 mounted on the bolt 55 between the check nut-s57 and lug 5-1, which spring tends to force the bearing member 50 to its uppermost position. Check nuts 59 on the lower end of the bolt 55 limit the upward movement of the bearing member 50. Secured to the eye 56 is a. rod 60 which extends to the usual treadle (not'shown). Se cured to the outer and free end of the shaft 48, by screw 61, is a beveled corrugated feeding wheel 62 which is arranged to support the sole; secured to the lower end of the shaft 28 is a beveled disk 63 that co-operates with the feeding wheel; secured to the lower end of the hollow shaft 21 is a serrated flap turning member in theform of a roll or disk 64 that co-operates with both the beveled feeding disk 63 and the feeding wheel 62. The feeding wheel 62 is of suliiciently small diameter to insure that it will not break down or flatten the more or less abrupt bend at the forward end of the shank portion of a molded insole. Secured to the bearing member 20 by a screw 65 is a guide 66 that co-operates with the channel flap turning roll 64. The periphery of the feeding wheel 62 may be transversely rounded as shown in Fig. 1, the better to adapt the wheel to oper-- ate upon soles of certain types, such, for example, as soles for so-callod cottage-shank shoes, in which the shank portion of the sole is molded so that it has more or less transverse curvature. Vl hen the feeding roll is thus rounded, the cross-sectional contour of its periphery will conform substantially to the transverse curvature of a molded sole so that the feeding wheel will contact with the sole substantially throughout the width of the wheel, and accordingly will not break down or destroy the molded transverse curvature of the sole. When, however, a flat portion of the margin of a sole is fed over a lower feeding wheel having a transversely rounded periphery, such as shown in Fig. 1, the wheel will. have a much more restricted area of contact 'with the sole and consequently a. minimum amount of resistance will be offered to the turning or swinging of the sole as it is fed along. An edge gage is adjustably secured to the frame portion 11 to guide the sole by engagement with the edge of the feather. The flap turning roll 64: is countersunk or recessed. to a suliicient depth to receive the beveled disk 63, as clearly shown in Fig. 3, and the disk 63 may be adjusted relatively to such flap turning roll by means of the bolt 18. The periphery of the disk 63 engages the shoulder at the root of the turned channel flap and thus has a gaging function supplementing that of the edge gage 80. By turning the bolt 18 the position of the feeding disk 63 relatively to the recess in the flap turning roll (Sal may be adjusted to vary the amount of projection of the disk 63 from said recess according to the thickness of the channel flap so that in cases where the channel flap is very thin the dislrrnay be raised until its feeding surfacr. is located only slightly below the bottom of the flap turning roll. Such adjustment also varies the effective width of the peripheral face of the flap turning roll according to the thickness of the shoulder at the base of the turned channel flap. The feeding wheel need not necessarily be corrugated as shown inasmuch as good results may he obtained by using a wheel having a smooth feeding surface. The wheel 62 being of comparatively small diameter, it has practically no tendency to flatten or destroy the mold of the sole.

it will be noted by reference to l and 2, that the shaft 28 is inclined at an angle to the perpendicular, and that shaft as is inclined at an angle to the horizontal, this construction making it possible to operate on a sole 69 that is held in a substantially horizontal plane, as the working face of the feeding wheel 62 is substantially horizontal. Further, the beveled disk 63 is held to the work at the most efficient angle, and it will be noted, by reference to Fig. 3, that the contact of the feeding wheel 62 with the sole 69 is practically a line contact while the disk 63 engages the sole practically at only a single point. This latter feature makes it possible to turn the channel. flap of different styles of formed solcs such as soles for cottage shank shoeswithout danger of deforming the soles. The turning of the flap is further faciitated by the shape of the radial teeth or Work-engaging portions of the flap-turning member, said teeth having their lower or operative surfaces inclined upwardly and outwardly, as shown in jl ig. 3, that as each tooth passes across the lip it ftuictions to turn the lip by an easy cain action which gently raises the lip and irces it back gradually. The tapering feeding wheel 62 is arranged with its iar er end engaging the sole nearer the edge of the feather, and since the lineal speed of the feeding surface of the Wheel. is greater at the large than at the small end, the feeding wheel will tend to impart a rotating or circular motion to the sole fed across it. This action causes the sole to hug the edge 80 as the sole is fed and relieves the operator of the necessity of continuously and carefully pressing the sole against the edge gage. The tendency of the sole to rotate against the edge gage as it is fed also facilitates very materially the turning of the sole at the toe and ball, the two critical points in the manipulation of the sole.

The frame member 53 is adjustable toward and from the base and portion 11 by means of a bolt 70 screwed into the portion '11 and cooperating with the slot 71 in the rearwardly extending lug 72 on the member 53 and by a bolt 73 in the base 10 ongaging with a rearwardly extending rod 74:. Fingers 67' and 68, on either side of the shaft 28, see Fig. 4, are arranged in guideways 75 and 76 respectively, gibs "W and. 78 secured to the portion 11 by bolts 79 holding the fingers in adjusted position. The free extremity of the finger extends into the channel forward of the flap-turning roll and is shaped to raise the channel flap sufficiently to insure that it will he properly ongaged and turned. by said roll. The linger 68 serves to prevent the portion of the sole which has been operated upon from curling upwardly and thus insures against injury thereto by the flap-turning roll.

The various worms and Worrn wheels are so proportioned that the hollow rotatable shaft 21 and therefore, the serrated flapturning rol 64, rotates considerably faster than the beveled disk 63 and the feeding wheel 62, these two latter rotating at prac tically the same speed. Thus the contact of the periphery of the disk 63 with the base of the channel flap is substantially a rolling contact and there is no frictional rub or tendency to cut, glaze or burn the flap.

The operation of our improved machine will be readily understood. The operator adjusts the disk 63, flap-turning roll. 64,

feeding Wheel 62, and fingers 6'? and 63 to function properly on the size and type of sole of which is is desired to turn the flap. The machine is then started in motion, and the treadle (not shown) is operated to lower the feed wheel 62 to allow the sole 69 to be placed in position, as shown in Fig. 3. There being but a. single line contact between the solo 69 and the feed. wheel 62, while the evcled disk 63 touches the solo at but single point, there no possibility of deforming the sole when ever the shape may be. The guide 66 re ccives the turned over flap as it leaves the turning roll and provides a substantial hearing area upon the turned flap this point,

thus helping to guide the sole 69 positively and surely, and preventing the sole from being thrown out of engagement with the rapidly rotating serrated turning roll 6st. The guide 66 is particularly useful when soles having more or less pointed toes are being operated upon to prevent the lispturning member from-tearing or injuring the flap at the toe of the sole. The guide 66 serves to retain the pleat-ed effect imparted to the flap by the turning member at the toe of the sole.
