shoe base or holder 20 and is held in position by stove bolts 22 through the corrugated rubber pad 21 or the ribbed metal pad 21a and screwed into the inverted shoe base 20 and the shoe top 13.

A safety spring member, or plate 17 is bent at its inner end around the pin 23, between the side walls 16a and 16b of the upright back portion 16, through each wall of which projects the hinge pin 23. The safety spring member 17 is recessed at 17a for a spring 2&- which is coiled tightly around the pin 23 at this point, with one end fastened to the top center of the safety spring member 17 at 2taby suitable means. When not in use the safety spring member 17 will be held in the enclosure formed by the upright back portion 16-, by the action of the spring 2 1.

WVhen in use as an'additional safety measure the safety spring member 17 is swung down and either pinned to the ground by a peg 25 thrust .through the hole 26. in the safety spring member 17 and into the ground, or fastened to wood floors or the like by means of a nail 27 through the hole 28', as shown in Figs. 4 and 1 respectively.

2. A safety shoe as in claim 1, the plate being provided with a spring which normally holds it in folded position.

3. A safety shoe as in claim 1, and a pad fastened to the bottom of the fixture to engage the surface on which the ladder stands.

In testimony whereof, I do affix my signature.
