19 Claims.

This-invention relates to machines for use in the manufacture of shoes and is illustrated herein as embodied in a machine for covering heels.

In an application for United States Letters Patent Serial No. 56,739, filed December 30, 1935, in my name, there is. disclosed a machine for applying a single piece of covering material to the rear and side faces of a heel and forinturning the top, the bottom, and the forwardly projecting margins of the cover against the marginal portions of the attaching, the top-lift receiving, and the breast faces of the heel, respectively. In

' order to complete the covering of Cuban heels,

for example, which have been partially covered by the use of the above-identified machine, it is commonpractice for the operator, after trimming the forwardly. projecting portions of the side cover to the desired widths, to apply the flap to the breast of the heel by hand, the margins of the forwardly projecting portions of the cover being applied to the median portion of the heel breast in overlapping relation.

It is an object of this invention to provide a machine which may be advantageously used to trim the forwardly projecting portions of side covers of heelsv to the desired widths and to lay such portions upon thebreasts of the heels in overlapping relation. With the above objects in view and in accordance with a feature of this invention there is provided in a covering machine means forsupporting a work piece, means for trimming the projecting margins of a cover secured .to the work piece towidths suitable to insure that the margins shall overlap each other when applied to the work piece,.and means for laying the trimmed margins in overlapping relation upon the work piece.

=Theinvention is illustrated with reference to a machine constructed and arranged to trim the forwardly projecting portionsofa cover,.which have been secured to the side and rear faces of a heel, to desired widths, and to lay the trimmed projecting portions of the cover in overlapping order to trim the forwardly projectthe median portion of the breast of the heel and is yieldingly movable widthwise of the breast. In order to brace the forwardly projecting portions of the side cover against the cutting pressure of the blade and to lay the forwardly projecting portions upon the heel breast, the machine is provided with a unit mounted for swinging movement about an axis which passes substantially through the center of transverse curvature ofthe breast of the positioned heel. The unit comprises a pair of anvils which successively bend the respective forwardly projecting portions of the cover toward the heel breast and force the margins of the same against the respective cutting edges thereby to cause the blade to trim the margins to predetermined widths. The unit also comprises a resilient roll positioned between the anvils for'laying' the forwardly projecting portions of the cover in overlapping relation upon the breast of the heel.

In order to enable the roll to lay the trimmed margins in overlapping relation upon the median portion of the breast of the heel the blade carrier is alternately moved by the unit in opposite directions transversely of the heel breast from its centralized position. The unit is moved toward the heightwise median plane of the heel from one side of the heel to trim and to lay one of the forwardly projecting portions of the cover and is then swung toward the plane from the other side of the heel to trim and lay the other forwardly projecting portion of the cover. The

amount of overlap of the forwardly projecting forwardly projecting portions of the side cover,

quicker and more uniformly than is possible by the present hand trimming and laying operation.

,These and other features of the invention, including certain details of constructionand combinations of parts, will be describe-d as embodied in an illustrated machine and pointed out in the appended claims.

In the drawings,

Fig. 5 is an enlarged perspective View partly in section, of mechanism for supporting a covertrimming cutting blade of the machine;

Fig. 6 shows in perspective a heel which has been covered by the above mentioned machine disclosed in application for United States Letters Patent Serial No. 56,739; and

Fig. '7 shows the heel illustrated in Fig. 6 after the forwardly projecting margins of the cover of the heel have been trimmed and have been laid upon the breast of the heel.

The illustrated machine is described with reference to laying the forwardly projecting portions 28 of a cover 22 which has been attached to the rear and side faces of a heel 24 and is commonly known as a side cover, upon the breast 26 (Figs. 3 and 6) of the heel in overlapping relation. The side cover 22 may be laid upon the side and rear faces of the heel and inturned slightly upon the lateral margins of the top-lift receiving, the attaching and the breast faces of the heel 24, as illustrated in Fig.

6, by the use of the machine disclosed in the above-mentioned application for United States Letters Patent Serial No. 56,739. The cover is then snipped in the vicinity of the upper and lower breast corners of the heel to insure that the cover may be laid smoothly upon the heel.

The forwardly projecting portions of the side cover are applied to the breast of the heel 24 positioned and clamped in the machine, by a roll 28 which is preferably made of resilient material such as rubber and is rotatably supported by a bracket 39 which is screwed to sleeves 32 mounted upon a rod 34. Mechanism for positioning and clamping the heel in the machine will later be disclosed in detail. The sleeves 32 may be rotated by a hand wheel 36 or may be operated by a crank lever (not shown) driven by a power-operated clutch (not shown) or other suitable mechanism constructed and arranged to produce the desired swinging movement of the bracket 38. Extending lengthwise of the bracket along .opposite sides respectively of the roll 28 are a pair of anvils 31. 38 which may be made of suitable material and are constructed and arranged to bend the respective forwardly projecting portions 20 of the side cover toward the heel breast 26 as the bracket 30 is swung toward the heightwise median plane of the positioned heel. The anvils 37, 38 are also constructed and arranged to engage the cutting edges 43, 4!, respectively, of a cutter or cutting blade 42 supported by a car rier 44. The roll 28 and the anvils 31, 38 swing as a unit.

The roll 28 is concave lengthwise in accordance with the heightwise curvature of the breast 26 of the heel and progressively lays the forwardly projecting portions 20 against the breast, the bracket 36 being temporarily stopped when opposing anvils 37, 38 (Fig. 3) have forced corresponding projecting portions 28 against cutting edges iil, 4!, respectively.

The carrier 14 is pinned to the rod 34 and is normally urged to a position above the median portion of the heel breast 26, as illustrated in Fig. 3, and is swung under pressure of the anvils 38, 3'! in clockwise and counterclockwise directions (Fig. 3), respectively, after corresponding projecting portions 283 of the cover have been trimmed. In order to cause the carrier 34 normally to assume the centralized position illusreceive the plate 54.

trated in Fig. 3 and to permit the same to be swung under pressure of the anvils 37, 38, a block 43 (Figs. 1 and 2) is pinned to the shaft 34 and engages the upper face of a slide 48 which moves along guides 50 screwed to the main frame and is normally forced upwardly by a spring 52. When the upper end of the slide 48 and the lower face of the block 46 are in surface engagement the carrier 44 is in a centralized position.

In order to trim surplus material from the forwardly projecting portions 23 of the cover when the margins of the same are forced against the cutting edges 40, 4| by the anvils 31, 38, respectively, the blade 42 is mounted for movement lengthwise of its cutting edges. The blade 42 is guided for movement lengthwise of its cutting edges 40, 4| by a plate 54 (Fig. 5) which is positioned between upper and lower carrier portions 56, 58, respectively, secured together by screws 60, the blade 42 being provided with an elongated slot 62 constructed and arranged to The blade 42 is normally moved to a rearward position by a spring 64 (Fig. 2) the respective ends of which engage the carrier 44 and a lug 66 (Fig. 2) screwed to the rear end of the blade 42. Rearward movement of the blade 42 under pressure of the spring 64 is limited by engagement of the blade with the end B! of the plate 54. In order to reciprocate the blade 42 against the resistance of the spring 64 there is provided a slide 68 (Fig. 2) which is mounted for vertical movement in the frame of the machine and has a cam face '10 formed at its upper end. Upward movement of the slide 68 which is operated by a hand lever 72 causes the cam face Hi to force the blade forwardly. The lateral portions of the cam face 16 are slightly rounded to permit the lug 66 to ride up the cam face as the carrier 44 is moved from a lateral to a central or neutral position.

After the left forwardly projecting portion 20 (Fig. 3) of the side cover has been trimmed to the proper length the hand wheel 36 is rotated to swing the roll 28 across the median portion of the breast 28 of the heel 24, thereby to cause the same to lay the margin of the forwardly projecting portion of the cover upon the median portion of the heel breast. It will be noted that the carrier 44 is swung under pressure of the anvils 31,

38 in order to permit the roll 28 to move across the median portion of the breast 25 of the heel. The blade 40 is spaced from the breast 26 of the positioned heel in accordance with the desired amount of overlap of the forwardly projecting portions 20 of the side cover.

After the left forwardly projecting portion 20 of the side cover has been laid upon the heel breast, the unit which comprises the bracket 30 and the anvils 31, 38, is swung about the rod 34 to the opposite side of the carrier 44 in order to lay the right forwardly projecting portion 20 (Fig. 3) of the side cover upon the heel breast. During such operation the anvil 38 forces the margin of the right forwardly projecting portion 29 against the cutting edge 4| and after trimming the forwardly projecting portion, the margin thereof is laid in overlapping relation with the first laid margin as the roll 28 moves in a clockwise direction. The anvil 38 swings the carrier 44 in a clockwise direction against the yielding movement of the spring 52 to permit the roll 28 to move across the median portion of the breast of the heel. The axis of the rod 34 passes substantially through the center of transverse curvature of the heel breastZB.

holes or recesses 12 and 14 formed in the attach ing face and the treadend of the heel, respectively, the jig holes "and 14 of heels of various sizes being located at uniform distances respectively from the breast 26 of the heel. T The jig holes-12 are shaped to receive corresponding rounded studs 16 of a gage 18 and the jig hole 14 is shaped-to receive the' rounded end portion 80 of an adjustable screw 82 which isv turned to permit the operator to place the heel in the machine and to remove the same therefrom. The positioned heel is securely clamped in the machine through the provision of a clamp screw 84 which may be forced against the attaching faceof the heel.
