T 0 all whom it may concern.

Be it known that I, REUBEN W. SMITH, a c tizen of the United States, residing at Ma- IlGi/lil, in the county of Lancaster and State of Pennsylvania, hav'einvented certain new and useful Improvements inlnsulated Rail double-base for supporting the rail ends,,

which base is intended to secure an e'llectivc stiil'ening and bracing of the base at the cen tral portion of the joint, and to resist and correct any tendency of the main rail supporting base section or sections from being forced or sprung away from a firm bearing contact beneath the rail ends.

The improved double-base construction contemplated by the present invention is designed to have special utility in connection with that class of insulated rail joints embodying a two part or sectional supporting base for the rail ends, whereby a separate, individual supporting base section is provided for each rail end, thereby admitting of such a disposition of the insulation that there is no insulating material required to be interposed between the rail bottoms and their} supporting basesections. Furthermore, in this type of insulated rail joints, the present invention is intended to generally improve the reinforcing and stiilening of the joint, while at the same time preserving the two part or divided supporting base wherein each ase section aii'ords one rail end the support of the ties on both sides of the meeting point of the rails, Without contact with the corresponding base section carried by the other joint bar.

With these and many other objects in view, which will more readily appear as the nature of the invention is better understood, thesemeconsists in the, novel construction,

. base 6-6 is. a.

combination, and arrangement of parts hereinaftermore fully described, illustrated and claimed.

The essential features of the invention above indicated are necessarily susceptible to a variety of structural modifications without departing from the scope thereof, but certain preferred embodiments of the invention are shown in the accompanying drawings, in which: i I

Figure 1 is a side elevation of an insulated rail joint constructed in accordance with the present invention. Fig. 2 is .a bottom plan view thereofl Fig. 3 is a longitudinal section of the joint, showing the rails in elevation. Fig. 4 is a cross sectional view of the joint, the line of section being on the line 44 of Fig. 3. r

Like references designate corresponding parts in the several figures of the drawings.

As indicated, the present invention is specially applicable to those types'of insulated rail joints embodying a two part supporting base for the rail ends, and wherein each base section affords a support for one rail end. Hence, various forms of insulated rail joints involving said featuremay be provided with the special reinforced base structure claimed herein. Likewise, the improvements claimed, may be associated with. side. joint bars of various designs, irrespective of whether these joint bars constitute the upright members of joint shoes or chairs, or are in the form of the wxmventional angle bars or splice bars ar ranged over the rail bases and disposed beneath the rail heads. However, a practical embodiment of the invention is illustrated by the type of joint shown in the ('lrawings, and the latter will now be particularly referred to. 111 said illustrated embodiment olthe invention the joint shown includes in its constructibn the service rails 1 and 2-, the opposite side joint bars 3 and 4, the usual series of joint bolts 5, and the two part or divided rail sup ortin'g base comprising the separate, indivir ual or single base sections 6, each ofwhich is arranged to provide a support for one rail end on both sides of the meeting point of the rail ends without contact with its corresponding or complemental' base section. In this construction, it will be observed. that the two part ordivided detached base, that is, sepa rate from the side joint bars 3 and 4 in the a lurahty of vertically arranged fastenin bo ts 9 located at each side of the joint an -55 passing through alined bolt holes 10, 11,-1md

sense of not being permanently formed therewith or united thereto, thereby admitting of an adjustment and clamping action for the 'oint parts which is of a practical value in holding and maintaining the same in firm bearing contact with the rails.

In addition to the feature of having each of the individual or single base sections 6 of such dime sions as to afford a wide and substantial supporting base for one rail end, each of said sections is formed at one side with an integral supporting arm extension 7, which is preferably continued out to the 0pposite end of the joint from the section of which it is a part so as to find a supporting rest on the opposite tie or sleeper, thereby carrying out the function of each base seci tion affording one rail end the support of the ties on both sides of the meeting point of the rails. This function is a characteristic of the two part or divided supporting base referred to, but in addition to such function, the said supporting arm extensions 7 of the opposite base sections 6 afford means for admitting of a supporting fastening connection between each of said sections and one of the side joint bars'of the joint.

The fastening connection referred to is preferably utilized in connection with side joint bars of the conventional angle bar formation, and with what may be termed a supplemental supporting sub-base 8 cooperating with the separate individual base sections 6-6 in the manner to be now explained.

This 'su plemental supporting sub-base 8 preferably consists of an extra base plate section arranged horizontall T beneath the main base sections 6-6 at t 1e central part of the joint, and of such dimensions as to extend the full'width of the joint so as to' be coextensive with the 'width of the two part base made up of the sections 66, while also extending a material distance to both sides of the meeting point between the rail ends, thereby bridging the joint between the adjacent inner ends of the separate base sections 6-6 and acting as a stiffening and bracing support for such ends of said base sections. double base referred to, wherein the main base 6 .6 for the rail ends is supplemented by another centrally arranged sub-base 8, and the several elements com rising this double-base are maintained in t eir pro er relation through the medium of the sa d astening connection, which serves to con 1e themain base to the side joint bars 3 an 4.

The fastening connection may consist of any suitable and practical expedients that wil subserve the necessary functions, but is usually provided for by the employment of This construction provides the.

12, respectively provided in the side joint bars, the individual base sections 66, and in the opposite end portions of the sub-base 8. In connection wlth this fastening, it will be noted that the same is renderedspecially effective by reason of the side bars 3 and 4 being-of angle bar formation so that thesame may be formed at their lower edges with the horizontally arranged foot flanges. 13 projecting beyond the base flanges of the rails. This admits of the fastening bolts 9 being located beyond the base flanges of the rails and serving to draw the parts together with a sufficient spring clamping action to insure the holding of the base sections 6 in firm contact with the rail bottoms, and the subbase 8 in firm supporting engagement beneath the inner ad acent ends of the base sections 6 at the center of the joint.

The insulation of the joint herein described terposed between the joint bars and the rail sides, and each of which sheets is continued at the bottom, along one end portion thereof, into a bottom apron extension 15 which is dropped into the gap between the side edge of one base section 6 and the supporting arm extension 7 of the other base section. Also, the insulation of one base section 6 from the other at the center of the joint, may be conveniently provided for by the usual insulating end post 16, whose base is widened so as to lproject below the rail bases into the interva between the base sections 6. Any of the 1 conventional bolt insulating expedients 17 osition, between t 1656 parts, of a base insuating sheet 18. Also, suitable bolt insulation 9 is provided for the bolts 9 and is preferably arranged between the same and the sub-base8 as plainly shown in Fig. 4. Of course, other insulating expedients could be resorted to without affecting the invention.

While oneform of oint has been described and illustrated to exemplify the invention, it will be understood that the same may be embodied in other designs of joints, and also various changes in the form, proportion, and minor details of construction resorted to without departing from the s )irit of the invention or sacrificing any of t e advantages thereof.
