Shoe 24 ShOWIl in dotted lines. This 50 ture is the provision of a foot protector including main shell, as shown, is formed by a pair of intera pivotally connected toe portion and instep porfitting Shells 25 and 25 having a teleSCODihg COH- tion with a single yielding means adapted to hold nection 21 at the top. Preferably the telescoping both portions on a shoe. connection comprises a ilat section 28 on the A further feature of the invention resides in shell 25 and a plate 29 which, as shown, may be 55 advantageously connected to the shell 26 by rivets to form with a at oiset top section 3D thereof a socket 3| adapted to snugly and slidably receive the hat section 28.

With the telescoping connection provided by the present invention it is possible to move the shells 25 and 26 laterally relative to each other to divers wide and close-spaced positions, and thus adapt the main protecting shell 2| to t shoes of different widths.

Now of particular importance it is to be noted that there is provided in the offset section 30 an aligned series 32 of holes 33, 34, 35, 36 and 31, in the plate 29 a series 32 of holes 33', 34', 35', 36 and 31' in alignment and registering respectively with the holes in series 38, and in the flat section 28 of the shell 25 a series 38 of holes 36, 40, 4|, 42 and 43 deposed at an angle to the aligned series 32 and 32' in the shell 26. As shown, a U-shaped spring 44 is secured to the underside of the plate 26 and is positioned so that the spring arms 45 thereof extend contiguous the series 32' of holes therein so that when a locking pin 46 is, for example, inserted in the mating holes 35 and 35' in the shell 26 and the hole 4| in the shell 25 the spring arms 45 snap into the pin groove 41 to hold the pin in position. In this manner the intertting shells 25 and 26 are locked from movement laterally relative to each other,

With this construction, also, it will be readily appreciated that when it is desired to adjust the shells 25 and 26 to accommodate shoes of different widths it is merely necessary to withdraw the locking pin 46, move the shells laterally relative to each other to bring the desired other holes in register and then insert the pin 46 in the registering holes.

Thus, assume that it is necessary to adjust the shells to a wider spaced position than shown. In such a case the shells 25 and 26 may be moved relative to each other until the hole 3T in the offset section of the shell 26 is in register with the hole 43 in the flat section of the shell 25 and the locking pin 46 then inserted. Similarly, if it is necessary to adjust the shells to a more closespaced position, they may be moved until tbe hole 33 in the offset section of the shell 26 is in register with the hole 39 in the at section oi the shell 25. It will be appreciated that the intertting shells may be locked in intermediate wide and close-spaced positions by moving the same so as to bring into register other of the holes.

For maintaining the shells 25 and 26 in proper position relative to each other longitudinally and for guiding them during their lateral movement there is carried between the offset section 30 and plate 29 in the socket 3| a pair of spaced guide pins 48 and 49 entering laterally extending slots 50 and 5| in the at section 28 of the shell 25.

If desired, however, instead of utilizing a pin and slot means to maintain the shells in proper position longitudinally relative to each other, there may be utilized the cooperating rib construction shown in Fig. 5. As there illustrated, a pair of transversely extending ribs 52 and 53 are formed on the shell 26 to respectively cooperate with ribs 54 and 55 in alignment therewith on the shell 25. Thus, adverse relative longitudinal movement of the shells is prevented by the engagement of the ribs. These ribs also serve to strengthen the shells, and thereby make possible the attainment of considerable strength even though light gauge metal is used. In all other particulars the construction shown in Fig.

5 is identical with the form illustrated in Figs. l through 4.

To provide a Support for the main shell 2| abutments 56 and 5l are formed on the bottom edges of the intertting shells 25 and 26 respectively. Preferably, and as shown, these abutments are provided by flanges 53 and 59 extending inwardly at the lower edges of the shells 25 and 26 and adapted to rest upon the Welt 68 of a shoe. In addition to serving as supporting means the flanges may also serve as a gripping means to engage between the welt and the shoe upper. However, as shown, spaced lugs 6| may advantageously be formed to extend inwardly from the flanges 58 and 58 to grip the shoe and to provide additional means for supporting the protector 28 on the shoe.

While the flange type abutment is preferred, a modified abutment 62 may be provided by curving slightly inwardly the lower side walls of the shells as shown in Fig. 3A. This modicd form of abutment is more fully described in my prior Patent No. 2,017,670.

Whether the abutment utilized is of the preferred form or the modified form shown in Fig. 3A, it is thus seen that when the intertting shells are adjusted laterally to the proper position and locked by means of the pin 46 that the protector 20 is effectively supported on the welt 60 so that should any objects be dropped upon the shoe the foot of the wearer would be fully protected from being crushed or otherwise injured due to an inadvertent slipping of the protector from the welt.

For insuring the maintenance of the protector in position on the shoe there is provided a novel yoke member 63 adapted to be inserted under the shank or instep portion 64 of the sole 65, having upstanding side anges 66 and 6T with hooked portions 68 and 69 respectively extending over the welt at opposite sides of the shoe.

Preferably this yoke member 63 is of a width in excess of that of the narrowest part of the shank portion E4 to enable its being easily inserted in position, but is narrower than the forward ball portion 'l0 of the sole and forward portion of the shank so that when pulled forwardly it will wedge against the rear sides of the latter portion. An eTective means for thus pulling the yoke member forwardly is provided by spring connectors 1|, each comprising a coil spring 'I2 havinga button 13 secured to the forward end adapted to be inserted in a suitable button opening 14 and pulled into an associated rearwardly extending slot 'l5 in each olthe side walls of the shells 25 and 26, and having a plate section 'I6 secured at the other end with a loose rivet connection to the respective upstanding side flanges 66 and 61 of the yoke member.

With this advantageous construction the yoke member is urged into wedging engagement with the sole and the protector is held firmly in posi tion on the shoe with the abutments resting upon the welt and drawn inwardly to grip the sides of the shoe upper. It is to be particularly noted that a foot protector constructed in the manner above described may be most easily adjusted to t shoes of diiTerent sizes and that when associated with the shoe may be easily and securely maintained in position by merely inserting or snapping the yoke member under the shank portion of the sole.

If desired, in order to protect the instep portion as well as the toe portion of the foot from injury from falling objects the intertting shells person wearing the protector.

25 and 26 comprising the main shell 2| may be extended rearwardly. Preferably, however, when it is desired to provide a shield for the instep portionof the foot there is provided a second main shell 11, of metal or other rigid material, shaped to provide a chamber 18 to envelope the instep portion of the shoe as shown in Figs. '1 through 9. This instep protecting shell 11, as in the case of the toe protecting shell 2 is formed by a pair of intertting shells '|19 and 80 having a telescoping connection 8| at the top. As also in the case of the intertting shells 25 and 26 lthe telescoping connection comprises a flat section 82 on the shell 19 and a plate 83 which, as shown, may be advantageously connected to the shell 80 by rivets to form with the nat offset top` section 84 thereof a socket 85 adapted to snugly and slidably receive the flat section 82.

For enabling a locking of the intertting shells 10iand 80 relative to each other in divers positions of lateral adjustment there are provided, as with the intertting shells 25 and 26 enveloping the toe portion, a series 86 of holes 81, 88, 89, 9|)A and 9| in offset section 84, a series 86 of holes 81', 88', 89', 90 and 9| in the plate 83 of shell 80 in register with the respective holes in the series 86, and another series 92 of holes 93, 94, 95, 96 and 91 in theV flat section of the other shell 19 disposed at an angle to the registering series 86 and 86 in the shell 80.

Also, a locking pin 98 with a locking groove 99 is provided, adapted to be inserted in position when the intertting shells 19 and 80 are moved laterally relative to each other to bring a selected mating hole in the series 92 in register with mating holes in the series 86 and 86. A U-shaped locking spring |00 may be advantageously secured to the underside of the plate 83 so as to position the spring arms |0| thereof contiguous the series 86' of holes to snap into the groove 99 of the locking pin.

Likewise, as with the intertting shells 25 and 26, there is provided for maintaining the shells 19 and 80 in proper position relative to each other longitudinally, and for guiding them during their lateral movement toward and away from each other, a pair of spaced guide pins |92 and |03 carried between the offset section 84 and platel 83 in the sock-et 85 and movable respectively in transversely extending slots |04 and |95 in the flat section `of the shell 19.

To support the instep protecting shells 19 and 80 there are formed thereon abutting flanges |06 and |01 respectively, which extend inwardly tn rest upon the welt of a shoe similarly to'the abutments 56 and 51 on the toe protecting intertting shells 25 and 26.

In addition, there are also provided on the shells 19 and 80 downwardly extending abutting lugs |08 and |09 respectively adapted to engage with the floor or other walking surface to further support the shells when aA heavy object is dropped thereon. Preferably, these lubs |08 and |09 are of such a length that they are normally main,n tained slightly clear of the walking surface by the fianges |06 and |01 resting on the shoe welt, but are close enough to the walking surface to quickly engage the latter when a heavy object strikes the protecting shells. This construction is advantageous in that it offers a supplementary support that when necessary will positively engage the walking surface, but which normally will be maintained clear thereof so as not to interfere with the walking of the workman or other Preferably the set of flanges |08 and |01 as well as the set of lugs |08 and |09 are used. However, either set oi these lugs may be used alone.

In order that the instep protecting intertting shells 19 and 80 may be maintained in proper re,- lation with the toe protecting interfitting shells 25 and 28 there are provided on the shells 19 and 80 pivot fingers ||0 and Ill adapted to be inserted in` the button openings 14 at the head of the button slots 15 in the shells 25 and 28. With this construction it is seen that a pivotal connection is provided between the toe and instep protectors and |2 so that the latter protector may movel upwardly and downwardly as the shoe sole is flexed during walking.

Also, it is to be particularly noted that when thus pivotally associated the forward portions of the instep protecting shells 19 and 80 are spaced above and slightly overlie the rear portions of the toe protecting shells and 26 so as to provide complete protection for the forward portion of the foot.

It is further seen that the inwardly extending abutting flanges |05 and |01 on the shells 19 and 80 are of such a width as to maintain the side walls of the latter sufficiently clear of the shoe upper to permit the spring connectors 1| to` pass on the inside thereof'.

To associate the two-part protector shown in Figs. 6 through 8 with a shoe the same general operations are entailed as when associating the single protector 20. In addition, it is merely necessary to properly adjust the shells 19 and 80 of the instep protector to the proper spaced relation to be supported on the shoe welt and to grip the shoe upper in the same manner as the shells 25 and 28 of the toe projecting part 29. IThe spring connectors 1| serve effectively maintain both protectors 20 and H2 in position on the shoe. nels 1| may also serve to locate and maintain the second shell 11 relative to the shoe.

If desired, and as shown in Fig. 6, a pivot connection ||3 may be provided between the intertting shells 25 and 28 of the toe protector 20 at the forward end thereof. With such a construction it is possible to disp-ense with the locking pin 49 as the pull of the spring connectors will serve to maintain the abutments and 51 on the' shoe welt and the gripping lugs or iianges r lil in engagement with the sides of the shoe upper.
