@uitrit giedre @stru-t @with Letters Patent N 93,298, dated .Aug-ust 3, 18695 IMIPROVED RAILWAY-SWITCH.

The Schedule referred to in these Letters Patent and making part :if the same.

To all whom itmay concern:

Be it known that I, CHARLES GREENMAN, of Scott township, county of Wayne, and in the State of Pennsylvania, have invented certain new and useful Improvements in Self-Adjusting Railroad-Switch; and do hereby declare that the following is a full,.clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construetion of a Aself-adjusting railroad-switch, and in the ar rangement of the devices hereafter set vforth and explained.

Theaccompanyilug drawing represents a plan view of my invention.

Letter A represents the bed of the road, upon which are placed thestationary rails B and the movable ones The movable rails are pivoted to one of the ties at one end, so that they can be moved baek and forth on the steel plates D; andeach has a spring, E, bearing against its side, of sufficient strength to shove the rail back into place after it has been moved.

Secured to the side of the rails() are the pieces G, (one of which tapers to a point,) which arev heid just far enough apart, by means of bolts, to allow the anges on the car-wheels to pass between.

As the wheels move ou to the movable rails, the flanges strike against the pieces\G, causing the rails O to move sideways far enough to throw the train on to the other track.

Through one end of each of these pieces and movabie rails there is an opening made, through which the guidesH pass, so es to guide the rails upon th ground. i

These movable rails represent the means by which the switch is changed from one track to the other, toward the right, without requiring the attendance of a switch-tenden In case it should be desirable to run on the lefthand track, a lever connected with the staple fi, in the right-hand movable rail, will enable a person so to adjust the rail as to direct the train on to the left-hand track.

Should the train be on the right-band track, and it is desirable to back down on to the .single one, the movable rail on the left hand can beoperated in the same way.

As soon as the .flanges on the wheels have moved the rails C, and the train has passed by, the springs E l immediately move the rails into place again.

I:`[avi n,-;f` thus described my invention, What I claim, and desire to secure by Letters Patent, is

lhe pieces G, secured to the sides of the movable l rails C, in combination with the said rails, splings E, uides H, and plates I), when arranged and operating substantially as shown. l Y

In testimony that I claim the foregoing, I have hereunto setmy hand audseal, this 28th day of May,

CHARLES GREENMAN. [n s.]
