TROLLEY-WIRE CROSSING.

SPECIFICATION forming part of Letters Patent No, 511,419, dated December 26, 1893.

Application led June 26, 1893. Serial No. 478,782. (No model.)

To @ZZ whom it may concern:

Be it known that I, HENRY GEIsE, of the city of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Trolley-Wire Crossings, of

which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part oi this specification.

zo My invention has relation to crossings for the conducting of trolley wires of electrical railways, and has for its object the construction of a crossing device by which the conducting wires are insulated from each I5 other and from the crossing device and a travel plate common to the two lines is so situated as to be in the path of travel of the trolley wheels of each road. v

Referring to the accompanying drawings, 2o Figure l represents an inverted perspective view of the crossing device forming the subject of myinvention. Fig. 2 is a perspective view of the same with the top plate removed, and Fig. 3 is a transverse sectional elevation through the center of the same.

In carrying my invention into eiTect I rst insulate each conducting wire at the point of intersection, the insulation extending for some distance beyond the grooved guiding 3o arms of the crossing device as indicated at :cin the various figures.

The crossing device comprises essentially three sections, A, B, and C; the portion, B, being provided with a series of radiating arms,

B', extending for some distance beyond the edges of the plate and grooved at b for the reception of the insulated portions of the conducting wires, the grooved portions of the arms being on a plane somewhat lower than the main body of the portion, B, and where the arms merge into the main body, the grooves incline upwardly and the wires are conducted through openings, b', formed in the center of the section, B, and intersecting each other at an angle corresponding to the angle or crossing of the two roads. The conducting wires extending through these openings, b', cross each other above the level of the portion, B, as shown more clearly in Figs.

5o 2 and 3 and are covered by the section, A, the latter having a dome-shaped central portion,

d, the inner face of which is provided with grooves, a', a2, forming guiding channels for the Wires. The lower section, C, which forms the travel plate for the trolley wheels, has its 5 5 opposite edges centrally recessed at c, and into these recesses t the inner ends of the grooved arms, B, and the conducting Wires are guided through the recesses and from thence through the slotted openings, b', and 6o from thence to the guiding slots in the dome,

o. The three sections are held together by a series of bolts, d, extending through openings formed in the sections, A and C, and the section, B, is thus lirmly clamped between the sections A and O and the conducting Wires held in place without danger ot' working loose during the crossing ot the trolley wheels.

Vith a device of this character the trolley wheel after leaving the conducting Wire has 7o a smooth flat surface upon which to travel and as the grooved arms are on a higher level than the wires, the trolley wheels will travel practically on the same level in crossing, as it does when in contact with the wire, as the bottom of the groove of the trolley wheel is in contact with the wire and the periphery of the opposite flanges of the Wheel travel upon the plate, C.

In order to prevent the wearin g away of the 8o insulation and the danger which might result from short circuiting, the grooves l), of the arms, B', are preferably of such depth that the insulated portions, a, of the conducting wires will be inclosed within the groove to S5 such an extent that the trolley wheel will travel upon the opposite flanges, c, of each arm rather than in contact with the insulat ing material, oc.

It desired the travel plate, C, may be formed 9o of insulating material, or may be insulated from the other sections, or all of the sections may be made of insulating material or insulated from each other but this is not considered necessary as the insulated parts of the wire are not exposed to wear and being perfectly inclosed at the point 0E intersection are fully protected from accidental injury or deterioration due to exposure to the weather.

Having thus described my invention, what ico I claim, and desire to secure by Letters Patent, is-- 1. A crossing device comprising, in coxn' bination, conducting wires insulated' at the point of intersection and crossing each other at a point above the normal level of the wires, and a travel plate provided below the point of crossin' g and upon which the trolley wheels of both lines are adapted to travel, substantially as specified.

2. A crossing device comprising, in combination, conducting wires insulated.y at the" point of intersection and crossing each other at a point above the normal level of the wires, and a travel plate also located above thenor'- mal level of the conducting Wires, and upon which the flanges of the trolley Wheels of both' lines areY adapted to travel, substantially as specified;

3. A crossing device comprising, in coinbination", the conducting wires insulated at the point ofintersection, a plate, as B, grooved arins extending therefrom and adapted to suppeirtl and guide the wires, and a travel plate provided below the plate, B, having its lower surface on a plane above the normal level of the conducting wires, substantially as Spec'itiedi 4. The'coinbination of the conducting wires insulatedat the point ofl im ersection, a',l plate,

as B, having central slotted openings;` b, grooved' guiding arms, B', extendingr from said plate, a covering plate, as A, and a travel plate', as C, provided respectively above and below the plate, B, and between which said plate, B, issecured, substantially as` specified.
