INSULATED RAIL-J 01N T.

Application tiled January 13, 1908.

To all whom it may concern.'

Be it known that I,REUBEN W. SMITH, a citizen of the United States, residing at Marietta, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements in Insulated Rail- Joints, of which the following is a specification.

This invention relates to rail joints of the insulated type, and has special reference to a novel and practical joint of this'character comprising means for providing a .solid metallic bearing 'support at theunder sides of the rail heads, and also maintainin a complete and effective insulation throng out the entire joint.

As a general object, the invention has in View a construction wherein no insulation is interposed between the heads of the rails and the metallic bars next to the same. This admits the heads of the 'rails taking a4 solid and direct bearing on the -joint bars, while also .permitting of such a dis osition of the insulating material as to re ieve the same from the pressure of the load without detracting at all from the efficiency ofthe insulation. In other words, the invention provides' a structure in.which a solid metallic bearing is secured for the rail heads, anda complete insulation of the joint is effected by an arrangement of insulation upon which practically no fiber strain is imposed..

With these and many other desirable `objects in view which will `readilyappearto those familiar withthe-.art as the nature of ,A the invention is better undertood, the same consists in tliejnovel constructiomcombination, and arrangement of parts hereinafter more fully described, illustrated and claimed.

The essential features of the invention are susceptible to embodiment in diferent'kinds of structures and in dierent ways without affecting the scope. of the invention, but a preferred embodiment of the latter is shown in the accompanying drawings, in which: l

. A rail joint constructed according to t e design and plan of thepresent invention embodies in its organization the service rails R, the side joint bars l, and the usual series' of joint bolts 2. These joint bolts are l-tted with any of the approved bolt insulating c xpedients 3 such as usually resorted to for 1nsulating the bolts from the joint bars, b ut the characterizing feature of the present 1nvention resides in the employment of joint bars having a direct metallic bearing with the rails, and which bars are discontinuous, that is termi-nate at or near the meeting ends of the rails, and therefore do .not extend continuously throughout the jointas do the ordinary angle bars or `splice bars commonly employed in rail joint structures both of the' standard and insulated types., It will therefore be observed that the joint is provided `withwhat may be termed two-part or d1- vided joint bars, so that there are separate joint bars or joint barsections for each rail,'

the same being arranged respectively upon v 'opposite sides of the' rails and tho-roughly insulated from one another in a manner to be presently explained. A

As indicated,` the separate joint bars for each rail are oflengths approximately equaling one-half thelengtli-'of the joint so as to terminate at or near thejoint between the meeting ends of the rails, and in the carrying out of the invention-these separate joint bars may be of any conventional or approved design according to the type of rail joint to' inthe lillustrated.embodiment o'f the-invenj tion, each joint bar consists of'the'- main 'upright section or'girder 4 formed at its upper edge with the usual' thickened bearing head 5 having a direct metallic bearing against edge the upright sectionfor girder 4 of each angle bar l has formed integrally therewith .anouttu1ned foot flange 6 overlying; the rail flan-ge and formed with an inclined bearingv face 7 ha1ving directmetalliccontact with the inclinedupper face'of fia-nge.
