ELECTRIC-RAILWAY SWITCH.

SPECIFICATION forming part 0f Letters Patent NO. 561,970, dated June 16, 1896.

Application iiled November 30, 1895. Serial No. 570,612. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM R. DAGGETT, of Dayton, countyof Montgomery, State of Ohio, have invented a new and useful Improvement in Electric-Railway Switches 5 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, reference being had to the accompanying drawings, and to the iigures and letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in electric switches for street-railways, and has for its object to provide an effective and simple switch-shifting mechanism, as will be hereinafter more fully described.

Referring to the annexed drawings, Figure 1 designates a view in perspective of a track having my improved switch devices thereon. Fig. 2 is a top view showing in section the case in which the electromagnets are placed. Fig. 3 is an end elevation of the track, showing the switch and inclosing case in section. Fig. i is a vie-w in perspective of the trolleywires and the cross-wires that are connected with the electromagnets.

In a detailed description of the invention, 1 and 2 designate, respectively, main and diverging tracks.

3 designates the tubular poles to which the cross-wires 4, that support the trolley- wires 5 and 6, are attached.

7 designates an inclosing case, which is provided with a suitably-insulated seat in the ground to a depth that enables the upper side S thereof to lie fiush with the surface of the ground, as shown in Fig. 3, and provides a fiat surface for the switch- tongues 9 and 10 to slide upon.

11 and 12 designate two electromagnets that are inclosed within the case 7. T0 one end of the helix of each of the electromagnets are connected wires 13 and 14, and 4the other end of said helices have a ground connection g g. The wires 13 and 14 are inclosed in and suitably insulated from the tubular posts 3. The upper ends of these wires extend upwardly through said posts and horizontally above the trolley- wires 5 and 6 and are connected to a non-conducting piece 15.

16 designates an armature that lies between the magnets and rests upon flanged rollers 17 17, that are suitably mounted in the case 7.

18 and 19 are lugs or stops on the said armature and on the bottom of the case, which are adapted to limit the movement of the armature as it is attracted in either direction by the magnets.

20 and 21 are pins that project from the 'upper side of the armature and penetrate with Wire 5, when it reaches the wire 13,will v convey current thereto, thus making a circuit for an instant between the trolley-wire and the electromagnet 11, which attracts the armature and therewith the switch in line with the diverging track. The trolley-wheel in contact with wire 6 will perform a similar function to shift the switch back to the main line.

The switch- tongues 9 and 10 are pivoted at a a,the ends farthest from the approaching car. Therefore I am enabled to dispense with the use of a frog.

Having described my invention, I claim- In an electric switch for street-railways, the combination with a switch, of electromagnets on the outside of said switch, an armature between said electromagnets, and connected to said switch, flanged rollers upon which said armature rests and is guided, wires 13 and 14 in the path of the trolley-wheels and adapted to convey current from the trolleywires to said electromagnets.

In testimony whereof I have hereunto set my hand this 21st day of November, 1895.
