The present invention relates to apparatus for forming a channel in a face of a sole in predetedmined spaced relation to the edges thereof.

Apparatus for this purpose requires means to turn a shoe sole, laid fiat on a support, relative to a fixed channeling knife to provide a channel a predetermined distance from the edge of the sole. Apparatus for this purpose has not been satisfactory in that the sole turning was manually effected.

The present invention has, as its general objective, the proivsion of apparatus in which this operation is automatically effected. In accordance with the invention, this objective is attained by providing sole channeling apparatus with a first mount attached to the upper surface of the flat sole support for adjustment transversely with respect thereto and having first rotatable members with their axes disposed at right angles to the support. A second mount carries a second rotatable member and is connected to the support for movement vertically relative thereto into and out of an operative position in which the axis of the second rotatable member is parallel to and close to the support. The second mount has a depending, channel-forming knife adjustably connected thereto. A third rotatable member is mounted below the support with its axis parallel thereto but with its periphery protruding therethrough and in the rotational plane of the second rotatable member.

The first, second, and third rotatable members are disposed and driven relative to each other to cause a sole to turn with its edge in contact with the first rotatable members when positioned with a face on the support between the second and third rotatable members with its edge in contact with the first rotatable member and with the second rotatable member in its operative posi tion.

In the accompanying drawings, there are shown illustrative embodiments of the invention from which these and other of its objectives, novel features, and advantages will be readily apparent.

The sole channeler shown in the drawings consists of a table-like structure providing a fiat support 10 common to the two sole channeling apparatus generally indicated at 11 anud 11A in FIGURE 1. As the apparatus 11 and 11A are shown as identical, except as to certain details 3,325,839 Patented June 20, 1967 of their drive, a description of the apparatus 11 will suflice. The corresponding parts of the apparatus 11A are, however, distinguished by the sufiix addition A to the appropriate reference numerals.

The apparatus 11, as may be best seen in FIGURE 2, consists of a first mount 12, the details of which may best be seen in FIGURE 4.

The mount 12 is slidably supported in the slideway 13 of its base 14 which has a captive screw 15 threaded into the mount 12 to enable the mount 12 to be adjusted relative to the base 14. The base 14 has parallel slots 16 and 17, the slot 17 being within and extending lengthwise of the slideway 13 and the mount 12 has a slot 13 in vertical alinement with the slot 17. The support 10 has a slot 19 through which locking bolts 20 extend with nuts 21 threaded on their lower ends, one bolt 20 extending through the slot 16 and the other bolt 21) extending through the vertically

alined slots

17 and 18. By this construction the mount 12 may be adjusted both relative to its base 14 and, with its base 14, relative to the support 10. In practice, the base 14 has a sole-size scale 22 and the mount 12 has a marker 23, see FIGURE 1, readable with reference thereto.

The amount 12 is shown as provided with a pair of first rotatable members, each generally indicated at 25 and having carbide-coated, replaceable rings 25 clamped to the lower end of a shaft 26 supporting a helical gear 27 and journalled in the chamber 28 of the mount 12 with its axis at right angles to the support 10 and with its ring 25 exposed for engagement with the edge of a sole 29. Also journalled in the chamber 28 is a helical gear 30 in mesh with both gears 27 and a driving gear 31 whose shaft 32 is journalled in the chamber 28 with its axis at right angles to the axis of the

gears

27 and 30.

A second mount, see FIGURE 2, generally indicated at 33 includes a portion 34 provided with end pivots 35 journalled in bearings 36 mounted on the support 10, a portion 37 rotatably supporting a shaft 38 provided with a rotatable member, and an intermediate bridging portion 40 between the front end of the portion 34 and the rear end of the portion 37. The axis of the shaft 38 is parallel to the surface 10 and to the slot 18 and the rotational plane of the second rotatable member 39 is at right angles to and intersects the slot 19.

The mount portion 34 includes a depending arm 41 extending downwardly through an opening 42 in the support 10 and is pivotally connected to the rod 43 of the double-acting, air operated device 44 having

air delivery lines

45 and 46, see FIGURE 9. The air line 45 is controlled by an adjustable, pressure regulating valve 47 having a normal position in which air is delivered to the device 44 to force the second rotatable member 39 downwardly into an operative position against the upper surface of a sole 29 under a selected pressure. The air line 46 is controlled by a valve 48 by which it is held closed except when the treadle 49 is depressed with the device 44 then being operative to raise the second mount 33 to permit the sole 29 to be removed and replaced. An adjustable stop 50 limits the travel of the rod 43 in a mount raising direction.

Secured to the undersurface of the support 10 is a frame 51, see FIGURE 2, having depend-ing bearings 52 in support of a shaft 53 provided with a rotatable member 54, hereinafter referred to as the third rotatable member. The support 10 has a slot 55 in the plane of the second rotatable member 39 through which the periphery of the third rotatable member 54 is exposed to be engaged by the undersurface of the sole 29. The third rotatable member 54 may be an abrasive wheel where marginal roughing of the downwardly disposed sole surface is desired.

At the other end of the shaft 52, there is a gear 56 below and exposed through an opening 57 in the support 10. Adjacent the ends of the opening 57, there are bearings 58 in support of

parallel shafts

59 and 60 provided with

gears

61 and 62, respectively, the gear 61 in mesh with the gear 56 and with the gear 62. A generally indicated universal joint connection 63 joins the shaft 38 and the shaft 60 thereby to enable the second mount 33 to be lowered into and raised upwardly from its operative position. A generally indicated universal joint connection 64 joins the shaft 59 and the shaft 32 thereby to enable the position of the mount 12 to be adjusted as required.

Fixed on a mount supporting structure for the support 10, is an electric motor 66 whose drive shaft 67 is the drive shaft of a speed reducer 68 on whose driven shaft 69 there is a sprocket 70. A chain 71 is trained about the sprocket.

70, a sprocket 72 on the shaft 53, under an idler sprocket 73 on a shaft 74 and about a sprocket 75 on a shaft 76. The shaft 76has a sprocket 77 connected by a chain 78 to a sprocket 79 fixed on the shaft 59A to rotate the gear 61A as the driving gear for the rotatable members of the apparatus 11A.

A holder for the channeling knife 80 is generally indicated at 81 and is detailed in FIGURE 6. The holder 81 consists of a housing 82 having a vertical slideway 83 for a slide 84. The upper end of the slide 84 has a threaded bore 85 to receive the screw 86 held captive by the housing 82 thereby enabling the slide 84 to be moved vertically in either direction by turning the screw 86 in the appropriate direction by means of its head 87. The slide 84 has a channel 88 opening through one face and slidably confining a nut 89. The opposite face of the slide 84 has a slot 90 opening into the slot 88. A locking screw 91 extends through one wall of the housing 82, the slot 90 and is threaded through the nut 89 to enable the nut 89 to be drawn into or released from clamping en gagement with the bottom of the channel 88.

At the lower end of the slide 84, there is an inclined shoulder 92 supporting a knife 80 which is detachably secured against the slide 84 by a clamping jaw 93 slidable in a transverse bore 94 in the slide 84 and movable into and out of knife clamping position by turning the screw 95 in the appropriate direction.

The holder 81 is adjustably attached to the part 37 of the second mount 33, the holder 81 having its housing 82 provided with :a bracket 96 for this purpose. An arm 97 is slidable in channel 98 and has a slot 99 through which a screw 100 extends and by which it and the channel 98 are attached to the mount part 37. A screw 101 threaded into the mount part 37 has a washer 102 engageable with the end of the channel 98 to clamp it against turning from a desired setting.

The bracket 96 is adjustably attached to the arm '97 :by

screws

103 and 104, the screw 103 functioning as a pivot and the bracket 96 having a rearward slot 105 arcuate with respect to the thus established pivot axis and receiving the screw 104. The

screws

103 and 104 are both threaded into a locking member 106. With this airrangement, not only is the knife adjustable vertically and lengthwise with reference to the second mount 33 but also it may be turned to vary the lay of its cutting edge without materially varying its position.

With the apparatus as thus described, and with the second mount 33 raised, a sole 29 is placed fiat on the support with the face thereof that is to be channelled disposed upwardly, its undersurface in contact with the third rotatable member 54, and its edges in contact with the carbide-coated rings 25 of the first rotatable members 24. When the second mount 33 is lowered into its operative position, the second rotatable member 39 engages the upper surface of the sole 29. The several rotatable members are now operative to turn the sole 29 automatically completely about with a channel 107 being accurately formed therein in predetermined relationship to the sole edge requiring only that the soles be manually placed on and removed from the apparatus.
