PATENTED JUNE 11, 1907.

MATTHEW H. MAHAR, OF BAY CITY, MICHIGAN.

DERAILING-SWITC H.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed August 80,1906. Serial No. 332,698.

To all whom it may concern;

Be it known that I, MATTHEW I-I. MAHAR, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Derailing-Switches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved derailing switch for use at railway crossings, side tracks and at other places where it may be desired to derail a car or train; and it consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Fignre 1 is a side elevation of a derailing switch embodying my improvements; Fig. 2 is a top plan view of the same; Fig. 3 is a vertical, transverse sectional view of the same, taken on the plane indicated by the line aa of Fig. 2; and Fig. 4 is a similar view, taken on the plane indicated by the line bb of Fig. 2.

The track rail 1 is of the usual construction. On the inner side thereof at a suitable point is my improved derailing switch point 2, which is pivotally mounted at one end, as at 3. The upper side or tread 4 of the derailing switch point is inclined longitudinally, as shown in Fig. 1, and at the free end of the said switch point the tread thereof is at a higher plane than that of the rail 1. The said elevated tread portion of the switch point is curved laterally, as at 5, to extend transversely over the rail 1 when the said switch point is closed against the said rail, as shown in the drawings. The said tread of the pivoted derailing switch point is provided with a longitudinal groove 6 to receive the flanges of the wheels of the car or train, the said grooves being curved laterally, as at 7, at the movable end of the derailing switch point.

It will be understood that when the derailing switch point is set as shown in the drawings, a train approaching at the directlon indicated by the arrow in Fig. 2, will have its wheels raised by the inclined tread of the derailing switch point, so as to cause its wheels to rise from the main rail 1 and run to one side of and become disengaged from said rail.

Any suitable switch mechanism may be attached to and employed for operating my improved derailing switch point, and I do not desire to limit myself in this particular.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

In combination with a railway rail, a derailing switch point at one side thereof, bearing against the same, pivoted at one end, movable toward and from the rail, and having an inclined tread rising from its pivoted point and provided with a longitudinal groove laterally inclined on the side next the rail, that portion of the tread at the free end of the derailing switch point being higher than and curved laterally to extend over and to project beyond one side of the tread of the first-mentioned rail, substantially as described.

In testimony whereof I have hereunto setmy hand in presence of two subscribing wit- IIGSSGS.
