4 Claims. (Cl. 3672)' This invention relates to safety shoes, and more particularly to a safety shoe which protects not only the toes of the wearers foot, but also the instep against objects which may fall thereon.

The provision of a steel metal toe cap in a shoe is well known. It isralso well known to provide steel bridges over the ball joint and also steel shields to buckle over the instep. A shoe having a steel bridge and instep shield while providing maximum protection is heavy, uncomfortable and causes unusual attention when worn on the street. Consequently, such shoes are not popular with workmen and they avoid wearing them'. Shoes having only Ia steel toe cap are readily acceptable Ito workmen, but these otfer no protection to the ball joint and metatarsal arch of the wearers foot.

The shoe of the present invention is most useful to mechanics and workmen, such as plumbers, carpenters, and the other construction workers who do a considerable amount of moving around in the course of their work and also those workmen, such as refrigeration repairmen and movers who go into private homes and oces in connection with their work. A workman wearing a shoe having a steel bridge and instep shield -would not only create unusual attention but would become very foot weary in the course of a days work.

Consequently, i-t is an object of the present invention to provide Ia safety shoe for workman which oiers the protection of a steel toe cap and lighter and comfortable protection over the ball joint and instep of the wearers foot.

It is a further object of the present invention to provide such a safety shoe which is conventional in appearance and may thus be worn to and from work as well as in the course of a days work without creating unusual attention.

Other objects and advantages of the present invention will become apparent to those skilled in the art from the following description when read in conjunction with the accompanying drawing wherein:

FIGURE 1 is a perspective view ot a shoe in accordance with the present invention, a portion being cut away to show the construction of the upper;

FIGURE 2 is an elevational sectional view of the toe and vamp portion taken on the line 2-2 of FIGURE 1;

FIGURE 3 is Ia transverse sectional view taken on the line 3 3 of FIGURE 2;

FIGURE 4 is an exploded view of the toe and vamp portion of a shoe upper in accordance with the present invention.

Adverting now to the figures and particularly to FIG- URES 1 and 2, there is shown a mans shoe having the conventional appearance of a street shoe of the simulated moccasin type and having an outer sole 10, a heel 11, an insole 12 and an upper 13. The upper 13 has a leather outer portion 14 and a leather liner portion 15, and comprises a quarter portion 16, a toe portion 17, a tongue 18 and a lacing means 19 in the vamp portion.

The present invention is concerned with the construction of the toe portion 17 and tongue 118. The toe p0rtion 17 extends from the toe of the shoe to the instep where it is joined to the heel portion 16 -by a line of stitching 20.

A metal toe cap 21 is positioned over the liner 15 at the front of the shoe las shown in FIGURE 4. A cap liner '22 of soft thin flexible material such as cotton ilannel is interposed between the leather liner 15 and the metal toe cap 21 to prevent'chang of the liner 15 and to add to the cushioning between the metal and the wearers foot. A strip of felt 23 which extends from the insole 12 on one side of the shoe to said insole on the other side is positioned so that its forward edge 24 is in edge abutting relation with the rear edge 25 of the metal toe cap 21. 'Ihe felt strip 23 acts as an additional cushioning means in the region of the break line of the shoe upper so that the wearers foot will be protected against the hard relatively sharp edge of the metal toe cap 21 when his foot is bent at the toe joints in walking. The cap liner 22 extends rearwardly beyond the metal toe cap21 t to the rear edge of the felt strip 23.

The tongue 18 has an inner ply 26 attached by a line of stitching 27 to the liner portion 15, and an outer ply 28 attached by a line of stitching 29 to the outer portion 14 of the upper 13.

A safety pad 30 made of a lthickened piece of tough, iiexible resilient material, such as foamed rubber or one of the foamed synthetic plastic resins as for example, foamed polyurethane synthetic resin or the like, is attaced to the outer portion 14 as by a line of stitching 31. This may conveniently be done at the time the moccasin cap 32 is adjoined to the outer portion 14. v v

VThe safety pad 30 extends longitudinally of the shoe from the forward top of the toe portion 17 to the free end 33 of the tongue 18 as shown in FIGURE 2. It is held within lthe tongue 18 by the line of stitching 34 joining together the

plies

26 and 28. The safety pad 30 extends substantially transversely across to the top of the shoe in the region between the metal toe cap and the base of the tongue 18 as shown in FIGURE 1. Thus, the safety pad 30 lies in substantially a foldable plane and is easily ilexed at the break-line of the shoe.

An insert 35 of cotton annel cloth or similar material is interleaved between the metal cap assembly comprising the :metal cap 21, the liner portion 15, the cap liner 22, the -feltstrip 23, and the inner ply 26 of the tongue 18 and the outer portion assembly comprising the outer portion 14, safety pad 30, moccasin `cap 32 and outer ply 28 of the tongue 18. The insert 35 extends longitudinally from the toe of the shoe to the base of the tongue 18. Thus, the metal toe plate is encompassed with a soft mapped cloth which will prevent the shoe from squeaking,

which might result from friction-al rubbing of leather or foamed plastic on the metal toe cap.

IDuring the lasting of the shoe the lower ends of the liner portion 15, the cap liner 22, the felt strip 23, the insert 35, and the outer portion 14 are brought together and joined to the sole of the shoe.

By interposing the safety pad 30 between the metal toe cap and the outer portion 14 and attaching it to the outer portion by means of a line of stitching 31, the outer portion 14 being securely attached to the sole of the shoe, the forward end of the safety pad is securely anchored. Also, the safety pad 30 is securely anchored to the quarter portion 16 by the line of stitching 20. Thus, the safety pad 30 is raised above the wearers foot so that the force of an object striking the shoe in :the region of the vamp yis cushioned not only by the compressibility of the safety pad, but also the tensile strength of the safety pad.

The safety shoe of the present invention is comfortable and llight in weight; and at the same time it affords maximum protection for the toes of the wearer, while protecting the ball joint and arch of his foot against serious injury from all but a crushing blow. Thus a workman of the class described who might inadvertently drop a tool, an appliance part, a piece of lumber, or the like, on his foot while wearing a shoe of the present invention would in all probability not suier a broken bone or serious injury to the ball joint or arch of his foot. Since the shoe may be given the conventional appearance of a dress' slipper, workmen wil'l'- not object to wearing the safety shoe of the present invention.

While there has been disclosed in the foregoing descripton a practical embodiment of the safety shoe in accordance with the present invention, it will be understood by those skilled in the art that variations in the implementation of the concept of the invention are within the purview and scope of the invention.
