Many persons, young and old, have falls every winter on the ice or snow which can be avoided if their shoes are fitted with ice creepers. A very efficient device of this kind, which any boy can make at home in a short time, is shown in the sketch. These ice creepers need not be removed from the shoes or boots until the winter is past, for they may be worn indoors without injuring the finest floor.
The two plates A may be made from either iron or steel - preferably the latter. An all-steel scraper, or A piece of a saw blade, makes good creepers. Draw the temper by heating the steel to a cherry red and then letting it cool slowly. It may then be sawn with a hacksaw, cut with a cold chisel, or filed into plates of the proper shape, as shown. The teeth are filed to points. The two L-shaped slots are made by drilling 3/16 in. holes through the plates, and then sawing, filing or chiseling out the metal between the holes. The projections at the ends are then bent out at right angles with heavy pliers or the claws of a hammer, and finally the plates bent to fit the curve of the heel.
The creepers are attached by means of round-head wood screws turned into the leather. In this operation place the teeth of the plates just below the bottom of the heel and turn the screws into the ends of the upright slots until the heads just bind. The plate as set when indoors or else not needed is shown at B. To place the plate so it will grip the ice, slide it to the right, which will bring the screws into the horizontal slots, as shown at C. - Contributed by Chelsea C. Fraser, Saginaw, Mich.
