vided with a switch rail or tongue .T, arranged to turn on apivot r. The said switch tongue is mounted on the casting K in the usual way. A pin 3, projecting from the tongue J through a slot t in the casting K, enters an arm a on the sliding rod L, placed in the switch pit below the track rail. To opposite ends of the said rod L, are secured cross bars 11,1), carrying armatures w, 20', which enter the coils a, 0. of the electro magnets M, M. The said magnets are furnished with short cores 1), and areinclosed in lead to prevent them from being acted upon by any water or moisture that may enter the pit.

The electromagnetic mechanism is inclosed in an iron box N, provided with cross bars 0, 0', through which the rod L slides, and on the rod L, between the arm 16 and the said cross bars 0, O, are placed buffers c, to prevent shock when thearmatures are drawn in either direction.

To some fixed support, preferably near the track rail, and in the path of the roller 19 of the contact maker E, are supported contact plates (1, (1 which are surrounded by insulation c. From the contact plate d a wire f extends to the magnet M, while the contact plate (1 is connected by the wire f withthe magnet M, and both of the said magnets are grounded on the wire g. The box containing the magnets is closed at the top by serrated covers in the usual way. \Vhen a car approaches a switch and the driver desires to open it, he depresses the rod 0, bringing the contact roller 1) into contact with the plate cl, as shown in Fig. 1, when the magnet M is energized,and its armature and the rod L attached thereto are drawn over toward the magnet, carrying with them the tongue J, bringing it into the positionshown in Fig. 6. Shouldhe desire to change the switch so as to cause the car to take the side track, he brings the contact roller 1) into contact with the plate (1 thus energizing the magnet M, causing it to draw the rod L and tongue J in the opposite direction.

The armatures w are each provided with a longitudinal groove to admit of the introduction of oil into the magnets.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. .In an electrically-operated railway switch, the combination, with the car and electromagnetic switch moving mechanism, of a contact-maker formed of a sliding springpressed rod, a fixed insulated contact spring, a movable contact spring carried by. the rod, a yielding contact lever, and-contact plates, sub
