SAFETY SHOE Filei March 26, 1956 25 Flaps".

ARTHUR H. Ru. nRn.

ATTORNEY Patented May 4, 1937 UNITED STATES eATssr orrics 12 Claims.

My invention relates to safety shoes and it has for an object to provide means to fit over the toe of a shoe to resist deformation of the latter by impact.

In many occupations requiring the handling and lifting of objects of various kinds, the hazard of personal injury because of accidently dropping articles on feet of workers should be guarded against. As the toe portion of a shoe is ordinarily well located for injury, in accordance with my invention, a stiff and impact-resistant shield is provided arranged to cover the toe.

A further object of my invention is to provide a shoe toe shield having means so that it may be readily attached to and detached from an ordinary shoe.

A further object of my invention is to provide a shoe toe shield having rearwardly inclined pins for insertion into rearwardly-inclined openings provided in the shoe sole, together with looking pins for insertion in openings provided therefor in the sole after insertion of the inclined pins in their openings.

These and other objects are effected by my invention, as will be apparent from the following description and claims taken in connection with the accompanying drawing forming a part of this application, in which:

Fig. 1 is a side elevation of a shoe showing my improved shield applied thereto;

Fig. 2 is a side elevational View of the shield drawn to larger scale than Fig. 1;

Fig. 3 is a front elevational view of the apparatus shown'in Fig. 2;

Fig. 4 is a longitudinal sectional view taken along the line IV-IV of Fig. 3;

Fig. 5 is a detail sectional view taken along the line VV of Fig. 3 and,

Fig. 6 is a detail sectional view taken along the line VIVI of Fig. 4.

Referring now to the apparatus more in detail, in Fig. 1, I show an ordinary shoe, at It], provided with the usual toe portion and having a sole l I, which, as is usual, has an outer exposed marginal portion I la. My invention is concerned with the provision of an armor or shield for the toe portion of a shoe and this will now be described.

The armor or shield comprises a body l2 conforming to and arranged to fit over the toe of a shoe, such body being made of any suitable stiff or impact-resistant material, such as steel and the like; and, if desired, stiffness and strength of the shield may be increased by forming the latter with ribs l3. As shown, the ribs I3 extend transversely of the toe and stiffen the intermediate portion thereof joined to the lower upright marginal portion. The upright marginal portion has adequate stiffness, not only because of its curvature, but also because the substantially vertical or upright disposition renders the material thereof highly efiective to resist any compression impact stresses. Furthermore, it is unnecessary to provide the ribs at the extreme toe portion for the reason that the latter is adequately curved or arched in a compound manner to be highly resistant to deformation in all directions. As the marginal portion is adequately strong without having ribs, the surface thereof is not deformed with the result that, not only may a closer fit of the shield with respect to the shoe toe be had, but also space is left for the fastening devices, as will be described.

The shield is held in place by front and back rearwardly-inclined pins l4 and I5 extending from the bottom edge l6 thereof, the pins l4 and I5 being arranged to fit rearwardly-inclined openings I l and I8 provided in the outwardlyextending marginal portion Ila. of the shoe sole.

The shield also carries movable locking pins l9 arranged substantially at right angles to the bottom edge It, the locking pins being arranged for insertion in locking pin openings 20 as shown in Fig. 1.

To assemble the shield with respect to a shoe, inclined openings I1 and iii are provided in the marginal portion of the sole by means of an awl, or the like, and then the shield is placed in position, with the inclined pins l4 and I5 arranged in the openings I! and I8, respectively, the locking pins l9 being retracted to the position shown by the dot and dash lines in Fig. 2.

The proper positions for the openings 20 may then readily be determined and such openings provided in the same manner as the openings H and I8, or the openings 20 may have been located and. provided at the same time as the openings El and 18.

With the pins 1 4 and IS in their inclined openings I! and I8 and with the locking pins 19 retracted, the next step is to insert the locking pins in the openings 20, and this is done by moving the locking pins from the position shown in dot and dash lines in Fig. 2 to the full line position thereof.

The locking pins are associated with spring means carried by the shield, the spring means normally serving to bias the pins H! to unlocked position and the pins being held in locked position by means of suitable abutments 22 carried by the shield.

Preferably, the spring means is provided by wire elements 23 connected to the shield at 24, the wire elements conforming to the shape of the shield and having its end portions constructed to provide the pins l4 and I9. With this type of construction, the locking pins are held in locking position by means of the abutment-s engage ing above the wires 23; however, if the wires 23 are deflected outwardly so as to freely pass the abutments 22, the spring effect in such wires will cause them to assume the dot and dash line position shown in Fig. 2 with the locking pins in unlocked position.

From the structure so far described, it will be apparent that the shield may be firmly locked to a shoe sole by the cooperative action of the front and back inclined pins M and I5 and the locking pins IS, the inclined pins l4 and I5 serving to anchor the shield in place and the locking pins preventing disengagement of the pins I and I5 from their openings I! and H3. The bottom edge It of the shield is preferably serrated,

' as shown at 25, so that such edge will bite into the upper surface of the shoe sole to resist being flattened or deflected by blows.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon asare imposed by the prior art or as are specifically set forth in the appended claims.

What I' claim is:
