i- I INSULATED RAIL-JOINT.

Specification of Letters Patent. 1

PatentedMay 20, 1913.

Application filed February 21, 1912. Serial No. 679,020.

To all whom it may concern Be it known that I, JOHN P. NOONAN, a

citizen of the United States, residing at North Side, Pittsburgh, in the count of Allegheny and State 'ofPennsylv-ania, ave invented certain new and useful Improvements in Insulated Rail-Joints, of which the following is a specification. I

My invention relatesto. the construction of insulatedrail joints employed to connect together the ends of the ralls in constructing a railway track, and more particularly relatesto the construction of insulated joints used in connection with. railway tracks employing wooden rail ties.

One object of my invention is to provide an insulated rail joint having novel means whereby the strength of the joint is materially increased with but a slight increase in the weight or amount of metal used in making the splice bars used in forming the joints.

Another object of my invention is to provide a rail jo1nt having means whereby the metal splice bars are efl'ecti-vely insulated from the track railsand having improved means whereby the bearing surface of the splice bars on the wooden ties is very largely increased and a more durable and lasting rail joint is obtained.

Still further objectsofthe invention will appear as the invention is more fully described hereinafter.

Referring to the. accompanying drawings forming part of this speclfication, Figure 1 is a lon tudinal side elevation of an insulated rall joint as constructedand arranged in accordance with. my invention and applied for, use to connect the ends of the track rails. Fig. 2 is a transverse section of the same, and Fig. 3 is a plan showing a detail of the splice bar as formed in accordance with this invention. a

In the drawings, the numeral 2. designates track rails having their adjacent ends secured together b means of trackbolts 3..

A wooden block 4 is'shaped to snugly fit between theopposite inclined faces of the head 5 and flange 6 and against the faces oftlie web 7 of the track rails one of these blocks being provided on each side of the web of the track rails.

Secured on the outside of the wooden filler blocks are the rolled metal splice bars 8 forming the novel feature of this invenwidth of the horizontal base flange.

' vertical direction,

. face of these tion As will be seen by reference to the drawings, the splice bars comprise flat horizontally extending flange portions 9 and 10 and vertical flange'portions 11 which extend upwardly from about the middle of the The base flange-formed by the flange portions 9 and ends 10 of they flange portion 10 extend horizontally on opposite sides of the vertical flange portions 11, so as. to provide a-wide flat bearing surface which bears on the rail ties 12 of the track.

The outer horizontally projecting portions of the base flange 10 located between adjoining ties 12 are bent downwardly. The

downwardly bent portions 10 extend for some distance on either side of the middle of-"the length of the metal splice bars in a arallel with the upwardly extending firings portions 11, and inclined portions 10 connect the vertical flange portions 10" with the flat portions 10 of. the horizontal base flanges 10. r The inwardly projecting base flange portions 9 extend beneath the'flanges 6 of the track rails 2 and a sheet of insulating material 13 is inter" osedbetween the upper surange portions 9 and the bot- ;tom surface of the rail flanges 6 so as toin-' sulate the rail flanges from the metal splice bars. The .side edges 13 of the sheet of fiber or other insulating material 13 are turned upwardly so as to extend between the marginal side edges of the rail flanges '3 and the adjacent surface of the vertical flanges 11 of the splice .bars. I 1

Thebolts. 3 securing the splice bars to the rails extend through suitable registering j holes provided in the vertical upwardly extending flanges ofthe splice bars, in the wooden filler blocks and in the web of the rails, and a ferrule or washer 14 formed of fiber and threaded on the bolts is located in the holes in the rail flanges so as to prevent contact ofthe metal bolts with the metal of the rail flanges.

The advantages of myinvention' will be apparent to those skilled in the art. By the I is very materially stifiened and strengthened and bending of the splice bars is 'pre-' vented. I

Modifications in the construct-ion of the splice bars and in the wooden filler blocks may be made Without departing from the spirit and scope of my invention as defined in the appended claim.

I claim A rolled splice bar comprising a base, an inte ral substantially vertical. flange exten ing lengthwise of the base at thelongitudinal center thereof, the middle portion of the base at one side only of the flange hav.

ing a girder portion bent downwardly into 5 a substantially vertical part and inclined parts connecting the ends of the vertical part with the horizontal part of the base, the base at the op osite side of the flange being continuous rom end to end of the 20 splice bar, substantially as described.

In testimony where0f,I have hereunto set my hand.

JOHN RNOONAN.
