HARRY MILLER, OF MORRISTOWVN, INDIANA.

RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 346,671, dated August 3, 1886.

Application filed April 22, 1886.

To all whom it may concern:

Beit known that I, HARRY MILLER, a citizen of the United States, residing at Morristown, in the county of Shelby and State of Indiana,haveinvented certain new and useful Improvements in RailroadFrogs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and u e the same, reference be ing had to the accompanying drawing, and to the'letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in railroad-frogs; and itconsists in certain novel features, hereinafter described and claimed.

In the drawing I have shown a perspective ments.

A is the railroad-tie, B the rails, and C the frog. The irog is provided with an extension, D, at one end, to which the rails 13 are fitted. The rails at the other end of the frog are so arranged as to guide the wheels of the passing car into a groove or channel, E. in the crown of the frog. The higher portion, F, of the frog is on a level with the top of the railsIand the groove E is ofa depth corresponding to the size of the flange on the car-wheel.

Upon reference to the drawing it will be seen that my frogisintended for useonly atthejunction of two crossing tracks, and, as shown in the drawing, is arranged for use on two tracks, upon which the cars are traveling from leftto right. For tracks upon which the line of travel is from right to left the frog will be reversed end for end. It will thus be seen that the car-wheel always enters upon the frog at the end opposite the extension D, which end I will call the entrance end of the frog. At the said entrance end I provide two ridges or Serial No. 199,755. (No mrdel.)

ribs, G, upon the frog, arranged slightly outside the rails and parallel to them. These ribs G extend from the end of the frog to the edge of the groove E, which extends across the frog at an angle, as shown. The purpose and advantage of these ridges will be readily comprehended. As the wheels enter upon the frog they have a tendency to turn from their course and follow the other track. This tendency the ribs G check and overcome, for the wheels in turning from their course will strike against the said ribs, and by them will be kept in their course, as will be readily understood. It will thus be seen that I have provided a cheap, simple, and effective device by which the derailment of cars is prevented, and by which the cars are kept to their course.

The advantages of this frog over anyother are, first, it does away with the guard-rail, thereby removing a dangerous foot-trap; second, it can be completed in the machine shop, whereas others are not complete until the guard-rails are spiked down to the ties.

Having thus described my invention, what I claim, and desire tosec'ure by Letters Patent, 1s-

1. A railroad frog having ribs or ridges at the entrance end on each side and above the crown of the frog, said ribs or ridges being located outside the intersecting rails and each parallel with its respective rail, substantially as shown, and for the purpose described.

2. The herein described and shown frog for railroad-crossings, consisting of the frog proper, 0, having the extension D and groove E, and ribs or ridges G, substantially as specified.

In testimony whereofI affix my signature in presence of two witnesses.

HARRY MILLER.
