March 21, 1939. .1, BAZZONI MACHINE FOR COVERING HEELS Filed June 3, 1937 Patented Mar. 21, 1939 UNITED STATES PATENT OFFICE MACHINE FOR COVERING HEELS Application June 3, 1937, Serial No. 146,303

13 Claims.

In United States Letters Patent No. 2,095,962, granted October 19, 1937, on an application filed in my name, there is disclosed a machine by the use of which the top projecting margin of a cover attached to the side and rear faces of a heel may be quickly and effectively inturned upon and secured to the attaching face of the heel.

It is an object of this invention to provide an improved machine of the type disclosed in the above-mentioned patent. With the above object in view, and in accordance with a feature of this invention, there is provided a. machine comprising a wiping tool bodily movable in an orbital path, means for operating the tool, and means for guiding past the tool a heel, a partially applied cover of which has a margin extending beyond an edge of the heel, to cause said margin of the cover to be applied to portions of the heel located adjacent to said edge.

The above and other features of the invention, including certain details of construction and combinations of parts, will be disclosed as embodied in an illustrated machine and pointed out in the appended claims.

In the drawing,

Fig. 1 shows in side elevation the illustrated machine, a portion of which has been broken away, in the process of applying the projecting margin of a cover which has been partially applied to a heel, to the attaching face of the heel;

Fig. 2 is a front elevation of the machine; and

Fig. 3 is a perspective View showing in detail the work locating gages and the wiping tool of the machine during the laying of the margin of the cover upon the attaching face of the heel.

The machine is illustrated with reference to applying the top projecting margin of the leather cover 22, which has been secured to the rear and side faces of a heel 24, to the margin of the attaching face 26 (Fig. 3) of the heel. Preparatory to applying the cover 22 to the heel 24 the flesh side of the cover, as well as the portions of the heel surfaces which are tobe covered, are coated with rubber cement or other suitable adhesive, the projecting margin 20 being adhesively secured to the attaching face of the heel upon being pressed against the same.

In order to apply the projecting margin 20 of the cover to the attaching face 26 of the heel, the heel and its cover are guidedv past a wiping tool 28, which is movable at a high speed in an orbital path 30 (Fig. 1), by

gages

32 and 34. The flexible wiping tool-28 has the general form of a plate the lower work engaging face of which is convex.

The gage 32 comprises an angular plate 36 which may be secured in different adjusted positions in a guideway 38 (Fig. 1) of the machine frame through the provision of a slot and screw connection M3, and which is bifurcated at its upper end to provide work engaging fingers 42 and a tool receiving slot 44. The gage 32 also comprises an angular plate 46 which has a pair of flanges 48 engaging opposite sides of the angular plate 36 and the upper end of which is provided with work engaging fingers 59. The angular plate 48 may be secured in different adjusted positions upon the angular plate 355 through the provision of a screw and slot connection 52.

Formed integral with the gage 34 is a deflector 54 which causes the projecting margin 20 of the cover to be bent progressively toward the attaching face 26 (Fig. 3) of the heel as the operator rotates'the heel guided by the

gages

32 and 34 past the wiping tool 28 in the direction indicated by arrow 56. The gage 34 comprises a pair of spaced rolls 58 which are engaged by the covered rim of the attaching face, the gage being adjustable along a guideway 60 (Fig. 1) of the frame of the machine through the provision of the screw and slot connection. 62. The lower end of the gage 34 is cut away to provide a slot 64 for receiving the wiping tool 28 during a portion of its orbital movement. Since the rolls 58 are engaged by the extreme upper ends of the side and rear faces of the heel and. the gage 32 is engaged by the attaching face 26 of the heel during movement of the heel past the wiping tool 28, the

gages

32, 34 may be described as being constructed and arranged to be engaged by angularly disposed faces of the heel.

The wiping tool 28 is riveted or otherwise secured to a carrier 66 (Fig. 1) mounted for sliding movement in a rotatable or pivotally mounted bearing 68 which is mounted in stationary bearings 10. In order to insure against the heel being splashed by oil, openings 12 are formed between the stationary bearings 10 and the mov- =17 able bearing 68. The rear end of the carrier 66 is pivotally connected to a crank '14 mounted upon a shaft 16 which is operatively connected through intermeshing gears 18 and 80 to a drive shaft 82. are readily accessible through the provision of a cover 84 secured to the frame of the machine by screws 86.

As the operator turns the heel guided by the

gages

32, 34 in the direction indicated by arrow The operating parts of the machine 56 (Fig. 3), the projecting margin 20 of the cover is progressively bent toward the attaching face 26 of the heel by the deflector 54 and is then forced against the margin of the attaching face of the heel by the wiping tool 28.

The wiping tool 28 conforms to the shape of the attaching face of the heel as it forces the projecting margin of the cover against the attaching face by a succession of strokes, each of which progresses toward the edge of the margin of the cover and is disposed at substantially right angles to an adjacent portion of the rim of the attaching face of the heel.

Although the machine has been described with reference to laying the projecting margin 20 of a cover which has not been skived to the attaching face 26 (Fig. 3) of the heel, it will be understood that the above machine may be advantageously used for laying margins which have been skived, for example, by the use of the machine disclosed in United States Letters Patent No. 2,029,304, granted February 4, 1936, on an application filed in my name.

Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
