` Lette/rs Patent=No. 83,510, dated Octobre/:'27, 1868.

^ MPRO'VED RAILROAD-SWITCH.

Be it known that I, MICHAEL KELLY, of St. Gnarles, inthe county of St. Charles, and State of Missouri, have made certain new and useful Improvements in Railroad-Switches; and I do hereby declare that the following is a full and clear description thereof, refer` ence being had to the accompanying drawings, and

to the letters o'f reference marked thereon.

The obj ect of this invention is to construct a switch,

for railroad-purposes, which shall so 'guide the wheels passing over it -as to vprevent their leaving the rails, although the switch-rails should not be setto those rails onryyhich tlenwhe'els may be travelling.

Itis obvious that in a switch so constructed, no displacement of the switch will cause a train to be thrown from the track.

The invention consists of att-aching, tothe sides of the switch-rails, lugs, on which the iianges of Y the wheels will climb up and mount over the rail, when it should be misplaced. It will be necessary, however, to use, in connection with this switch, wheels of a peculiar construction, having a central flange, and two equall or nearly equal faces or' treads. i

To enable those skilled in the art to make and use my improved switch, I will proceed to describe its construction and operation.

Figure 1 of the drawings is a plan of the improved 4 switch.

Figure 2 is a side elevation o the same.

The switch-rails A are coupled with the rails A of the main track, or with therails B of the side track, in the'usual manner, and they may be thrown over, so as to couple. with either track, by means of the switch- "rods a c, in the usual manner. Attachedv to the outsides of the switch-rails' :are lugs C C', the top faces of which present inclined planes, as shown in iig. 2.

In connection with this switch it will be necessary to use wheels having central iianges, and two equal or nearlyv equal treads or faces, as is exhibited by the wheels D D'. The guard-rails E will be about the same as those in common use by the sides of switch.- frogs, the ends of them being curvedslightly inward, to prevent the wheel-ang'es from striking on the points of them.

The switch being constructed as above described, and the switch-rails being 'set to the side track, as exhibited in fig. 1, .and the wheels D D approaching the switch-rails, the 'iiange d, of the wheel D, lwill strike on thelug C, ai'x'd run up on top of it, and so on over the top of the switch-rail, until the tread of the wheel drops down en .top of the rail again in its proper position. In approaching the ends of the switch-rails, when they are thus misplaced, the inside tread of one of theggwheels will run on the loutside of the switch-rail on one side, and the inside tread of the other wheel on the guard-railE, until the proper position is attained.,-

Having described my invention,

What I claim, is The lugs C C and guard-rails E E, when arranged, relatively to each other, as set forth, in combination with switch-rails A, as shown; for the purpose exr plained.

In testimony of which invention, I hereunto set my hand in the presence of` Witnesses:
