Specification of Letters Patent.

Patented Mar. 17?, 1914- Application filcd May 12, 1913. Serial No. 767,102.

To all whom it may concern Be it known that I, Josnrn WV. Romans, a citizen of the United States, residing in l/Voodbury, county of Gloucester, and State of New Jersey, have invented certain Improvements in Insulating and Supporting Mechanism, of which the following is a specification.

My invention relates to insulating sup ports for third rails of electric roads, and its primary object is to provide a simple, compact and e'ilicient construction that will permit the use of narrower ties or bearings than have heretofore been required.

In the usual practice of the prior art it has been customary to use an insulating support for the rail and a support for the protecting board placed side by side upon the tie, which necessitates the use of ties of considerable width, as well as sound ends of considerable breadth.

It is a desideratum to have a construction which permits the use of ties of moderate width and ends which may not be wholly sound or of full width. This is accomplished by my invention in which the insulating support for the rail fits over the base of the support for the protecting board, and in the preferred construction such supports have a common median plane approximately coincident with the screws by which the said base is fixed to the tie.

In the accompanying drawings, Figure 1 is a transverse vertical sectional view of part of a track having my improvements applied thereto; Fig. 2 is an elevation of a section of said track at right angles to that shown in Fig. 1; and Fig. 3 is a bottom View of the insulating support.

The mechanism, as illustrated in the drawings, comprises the tie 1, the rail 2 for carrying the rolling stock, the third rail 3 for carrying the current, the insulator I which bears upon the tie and carries the rail 3, and the supporting strut 5 having the base 6 which is fixed upon the tie by the lag screws 7 and the top arm 8 to which is fixed the protecting board 9 by the bolts 10.

The insulator 4; is provided with the top seat 11 for the rail 3, the central bottom channel 12 which fits over the base 6, the recesses 13 which fit over the heads of the lag screws 7, and the channels 14: which extend transversely to the channel 12 to facilitate evaporation and secure ventilation.

This construction thus brings the base of the protecting board support within the sides of the insulator and permits such support and insulator to be placed upon a comparatively narrow tie or narrow part of a tie, so that a narrow tie or a tie with a defective or only partially sound end may be used, which would not be practicable with the former construction having the base of the protecting board support placed at the side of the insulator.

Having described my invention, I claim:

1. In an insulating and supporting mechanism, an insulator having a seat adapted for supporting a rail and a bottom channel extending transversely to said seat from side to side 01 said insulator.

2. In an insulating and supporting mechanism, an insulator having a seat in the top thereof and a channel in the bottom thereof, said channel having terminal recesses.

3. In an insulating and supporting mcchanism, the combination with a tie, oi. an in sulator having a bottom channel extending longitudinally of said tie and a supporting device having a base resting on said tie within said channel.

4. An insulating and supporting device comprising a top seat, a channel extending transversely thereto, said channel having terminal enlargements, and bottom channels extending transversely to said channel first named.

5. The combination with a tie, a rail and a protecting device for said rail, of a protecting device support having a base extending longitudinally of said tie, lag

screws passing through said base into said cess and supported independently of said 10 tie, and an insulator having a channel fitfirst device. ting over said base, recesses within which In testimony whereof I have hereunto set the heads of said screws are disposed and a my hand this 6th day of May, 1913, in the seat for said rail. presence of the subscribing witnesses.
