(01. 36—77) 1 2 This invention comprises an improved process of manufacturing a safety shoe having greater projecting end of the inner insole section; The lined upper is then assembled on the last, pulled over, staple side lasted, and heel lasted, all in strength and better shoe making characteristics than have been found heretofore in shoes of this type, by a series of steps which facilitate the the conventional manner and exactly as if no shoe making operations in general and avoid di?i metal box toe were to be employed. After the heel’ lasting operation, the pulling culties which have been heretofore encountered in manufacturing shoes of this special type. For example, the welt sewer has heretofore experi releasing the lined upper so that it may be pulled back to expose the tip of the last with the smooth enced a great deal of difficulty in breaking nee dles by striking the steel box toe. By the proc ess of my invention this difficulty is substantially if not entirely avoided. over tacks at the tip of the shoe are removed thus 10 insole section on the bottom thereon. The op erator may now conveniently place the metal box toe in position upon the toe of the last so that it encloses the toe portion of the smooth in sole section with its transverse tie bar lying ?at ‘ The strength of the steel box toe depends large ly‘upon its having an adequate tie or strut in 15 on the outer surface thereof. The insole tack is now removed from the projecting end. of the in the shoe bottom between its curved sides.

From the fore some extent with the ?exing of the shoe and making difficult the necessary shoemaking oper These difficulties are avoided in accord ance with the present invention by forming a metal box toe with a thin sheet steel tie, or by ' ations. providing it with prongs which may be punched into a portion of the insole which thus becomes a 20 going explanation it will be seen that the base contour of the metal box toe lies within the con tour of the projecting toe portion of the ribbed insole section and that the transverse tie bar is covered and concealed thereby, being now located between the two insole sections which have been separated up to this stage of the shoemaking tie for the box. process.

It may be noted at this point that the tip of the inner section I9" is to be enclosed within the metal box toe and that the inner section is made shorter than the complete ribbed section to compensate for this thickness and to bring the tip surface of the metal box toe into registration with the- end of the ribbed tip section. The composite insole shown in Fig. 1 is now tacked to a last I5 inthe usual manner, the tip I4 being temporarily removed, andv the upper H is pulled over and tacked in accordance with the usual shoemakingoperations.

McKay‘ or Comp-o shoes may be manufac tured in general as above described and in those cases the rib of the outer insole section will be eliminated. The essential characteristic of my improvement is the employment of a composite insole with a displaceable tip portion and any of » the standard shoemaking vprocesses may be car ried out in this manner without being otherwise modi?ed from conventional procedure.
