the upper insulation plate 5 constitutes the f 'u rail head insulation and is interposed be tween the under side ofthe rail head and the upper edge of the splice bar. Correspondingly, the separate lower insulation plate constitutes the base insulation for the joint and includes flange section 8 overlying the rail flange and has formed integrally therewith an upstanding web portion Qlying next to the web of the rail. The said flange s'. tion 8 of the base insulation is also formed integrally at its outer edge vwith a horizontal inwardly extending base section of in sulation 1() which'underlies the rail base and forms with the/flange section 8 a cud which completely receives and insulates the rail base flange.

In the embodiment of the invention shown l in Figs. 1 and 2 of the drawings, the rail head insulation, consisting of the upper insulation plate underlying the rail head at each side of the rail, is disposed wholly above th'e top line of the joint bolts, and therefore has no contact or engagement with such bolts that would require any machining of the said upper insulation plate to meet varia- I tions in bolt spacing,

thereby permitting the said plate to be manufactured in standard size and quantities. regardless of bolt spacing. This is provided for by the novel manner in which the upper and lower insulation plates are constructed and interlocked. As plainly shown in F ig. 1 of the drawings, it will bel observed that the upper.

insulation plate 6 not only lies wholly above the line of the bolts, but is also formed at its lower end edges with cut out portions l1, forming shouldered retaining seats .which receive the upper shouldered ends 12 of extension holding ears 13. These are extended upwardly from the main' web portion of the base insulation plate 8 and project a sufficient distance from the body of the plate so as to extend above the line of the bolts, and thereby interlockV with the retaining seats 11 of the upper insulation plate. Furthermore, it will be observed that this construction involves the formation between oppoproviding a maximum clearance between the joint bolts and the holding ears of the'base insulation plate, it will be noted, in the form of construction shown in Figs. l and 2, that the said base insulation-plate is provided at the central-portion thereof with a single or douhlefholding ear 13-13 to meet the situation of separateV upper insulation plates 6 being employed for the separate rails.

' bolts of the joint.

13y df a cut away space 1.4.

.preferably provided at its side edges with side locking tenons 16 engaging side keeper slots 17 in the web portions of the base insulation and at the bottom with a bottom locking tenon 18 which engages and interloeks with bottom keeper slots or notches 19 formed at the centers of the base sections 10v of 'the base insulation.

It will thus be seen that the combination ofinstrumentalities described, including the insulated end post, provide a very effective interlock for the various pieces of insulation to prevent longitudinal displacement thereof, while at the same time permitting such pieces of insulation to be made in standard quantities without having'to be mad chined for different spacings of bolts, and also permitting the various pieces of insulation to be independently removed orV replaced as the condition of the joint may require.

The same principles of construction will apply to all applications of the invention as may be exemplified by the modification of Fig. 3 of the drawings. In this modificam tion, the upper insulation plates are` illustrated'as being provided at their extreme inner ends only with deepened portions forming shouldered retaining seats 20, into which project the single extension holding ears 2l which are formed at the central part of the base insulation and project upwardly through the space between the two center In this form of construction cut away bolt clearance spaces 22 are provided above the web portion 9 of the base insulation, said spaces being of greater longitudinal extent than themaxi mum customary spacing of four-bolt joints. Fig. 3 shows them in use with Va six-bolt joint. They can thus be used in joints with' six or more bolts, usual spacing of the bolts. Also, in the modified constructiomthe combined width of the central holding ears 21 is less than the least customary spacing between the two eentagal bolts of a joint. Y

Other modifications and forms of construction may be resortedto, within the scope of the appended claims, without departing from the principle or sacrificing any of the advantages of the invention.
