I am aware that prior to my invention safety devices, frog-protectors, and footguards for frogs, guard-rails, and switches have been constructed of spring -steel. I therefore do not claim such material in the manufacture of guards as broadly new; but

What I do claim as my invention, and desire to secure by Letters Patent, is

1. A foot-guard for railways, consisting of a spring-steel bar having one end bent downward and extended at an angle with an opening therethrough to receive afastening-spike, and the opposite end bent down and under in a curved line and of bifidate form to provide a double-spring action at the free end of the bar, the said front end of the bar being reduced in width, substantially as and for the purposes set forth.

2. A foot-guard for railways, consisting of an elongated spring-steel bar having both ends bent downward, one of said ends being secured and the other free, the free end being bent under or backward in a curved line and of bifidate form, and a leaf pivoted on the top surface of the bar to modify the resiliency thereof, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses. V Brockville, April 23, 1891.

WILLIAM DRISCOLL.
