INSULATED TWIN JOINT.

SPECIFICATION forming part of Letters Patent No. 739,469, dated September 22, 1903.

Application filed May 2a. 1903.

To all whom it may concern.-

Be it known that I, GEORGE A. WEBER, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Insulated Twin Joints, of which the following is a specification, illustrated by drawings.

This invention relates to insulated railjoints, but more particularly to insulated twin joints or to the insulation of any desired number of rails nested together and provided with insulated joints between the rail-sections.

The object of the invention is to enable one or more rails to be efticiently insulated at the joints, while at the same time afiording a tear and is simple in construction.

Further objects of the inventionwill hereinat'ter appear; and to these ends the invention consists of a rail-joint for carryingout the above objects embodying the features of construction, combinations of elements, and arrangement of parts, substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which- Figure 1 is a top planviewof an insulated twin joint embodying the invention. Fig. 2 is a transverse sectional view of the same on the line as wot Fig. 1 looking in the direction of the arrows. Fig, 3 is anothertransverse sectional view of the same on the line y y of Fig. llooking in the direction of the arrows. Fig. 4 is a top plan view of another joint,

' showing the insulation of several rails nested row for double track, or running gauntlet/T as the term is used. One ormore tracks must Fig. 5 is atransverse sectional View semi No. 159,074. (no model.)

andit may then be desirable to insulate the v joints of two or four'or six or any desired number of tracks, the rails of which are nested together. At those portions where one track merges into another the rails will not be parallel, which .further adds to the difficulties of suitably insulating such a joint.

In Fig. vl an insulated twin joint is shown, in this instance'the joint being at a point where the tracks are'converging, and the parts of the joint are therefore adapted to the angle formed by the rails.

i The ends of the rails Aand Bare insulated fromeach other, as are the ends of the rails O and-D, the rails A and B forming the main rail an'dOand'D forming what is called the slip-rail? or guard-rail, and all of the rails are suitably braced and secured together toform a simple,oompact,' and. efficient insulated rail-joint. Suitable rail-supports are shown for 'the rails, in this instance railchairs E'and F being illustrated. Each chair comprises an upright G anda base, in this instahce the base H of one chair being shown I considerably narrower than the base I of the other chair; Sinoe'the rails are not parallelto'each other, the inner edge of the base of one of the rail chairs must be constructed at an angle, and in this instance it is found pref erable to construct thechairhaving the narrow baseH with anedge J, arranged at an directly upon the insulation K, whilebeneaththe base of the rail 0 is arranged an additional layer of insulation L, which may be fastened to the other layer K by means of angle to the upright G. The base I of the I suitable rivets O, of insulating material. This arrangement is provided in order to slightly l raise the rail 0. Provision must be afforded for permitting the rails A and C to lie at an angle with the base of one rail overlapping that of the other, because the rails are not parallel to each other. In this instance the upper portion of the base of the rail A is cut away or tapered along a line coincident with the point P, so that the base of the rail 0 may overlap and lie upon the base of the rail A. The tapering proceeds in the direction of the convergence of the rails. According to this construction the bases of the rails are not reduced in width or made narrower and thereby weakened.

Between the converging rails are arranged the filling-blocks Q, which may be either of metal, as steel, or of wood, and between the webs of the rails and the uprights G of the angle-chairs are arranged the filling-blocks Rot suitable material"as, for instance, wood or metal. In Fig. 1 they are shown of metal, and they do not extend across the joints in this instance. The parts of the joints are held together by suitable bolts S, which are insulated from the uprights of the anglechairs by suitable insulating-collars T. Beneath the heads of the bolts and the nuts are arranged metallic washers U, which are insulated from the uprights of the angle-chairs by means of insulating-washers V, whereby the bolts are insulated from the metallic parts of the joint, which would cause a short circuit were the path of the current to be continuous.

In the form of joint shown in Fig. 4 three nested rails are provided with insulated joints. In this instance a and b constitute the tread-rail, upon which a portion of the tread of the wheel runs, 0 and cl constitute the service-rail, which takes the principal part of the wheel-loads, ande andfconstitute the guardrail, all of the rail ends being insulated at the joints.

Two rail-chairs g and h are shown provided with uprights 'L, and the base 3' of the chair 9 is narrower than the base of the chair h.

A piece of insulation Z extends over the bases of the chairs and insulates the bases of the rails from the chairs. The guard-rail fand service-rail d in this instance are shown rest ing side by side upon the insulationl and supported by the bases of the chairs, while the tread-rail b is arranged with its head in contact with the head of the service-rail d. The same construction applies for the rails a, c, and e at the other side of the joint. As shown particularly in Fig. 5, the base of the rail b is cut away and so recessed thatit may be extended over the base of the rail d to bring the heads of the rails into contact with each other. Suitable filling-blocks 0 are arranged between the webs of the rails, these filling-blocks being of metal.as, for instance, steel-or they may be of wood. Suitable filling-blocks p, which may be of wood, are arranged between the webs of the outside rails and the uprights of the angle-chairs. The bolts q secure the parts of the joint together and, as shown, are suitably insulated from the uprights of the rail-chairs.

This invention is not tobe understood as being limited to the construction shown in the drawings, for the drawings are to be taken as merely illustrative of the broad principle involved in this form of insulated joint. Any desired or suitable number of converging railsections may be combined and nested and provided with insulated joints, and it is not essential to the invention that the rail-sections should be converging, for they may be parallel, and any desired number of rail-sections may be utilized in the parallel form of joint.

Obviously some features of this invention may be used without others and the invention may be embodied in widely-varying forms.

Therefore, without limiting the invention to the construction shown and described nor enumerating equivalents, I claim, and desire to secure by Letters Patent, the following:

i 1. An insulated rail-joint,comprisingaplurality of rail-sections and a suitable support for the same, the base of at least one of the rail-sections being cut away to aiford provision for the overlapping of the base of one of the other rail-sections, means for insulating the rail sections from the support, fillingblocks arranged between the rail sections, and insulated bolts for securing the parts of the joint together, for substantially the purposes set forth. 7

2. An insulated rail-joint, comprising converging main and slip-rail sections and a suitable support for the same, the base of one of the convering rail-sections being cut away to afford provision for the overlapping of the base of the other converging rail section, means for insulating the rail-sections from the support, filling-blocks arranged between the converging rail-sections, and insulated bolts for securing the parts of the joint together, for substantially the purposes set forth.

3. A rail joint, comprising two opposite rail-chairs each having a base and an upright, main-rail sections and slip-rail sections supported upon said chairs in converging lines, the base of one of the converging rail-sections being cut away to afford provision for the overlapping of the base of the other converging rail-section, insulation between the bases of the rail-sections and the bases of the anglechairs, filling-blocks between the rails and between the rails and the uprights of the angle-chairs, and insulated bolts for holding the parts of the joint together, for substantially the purposes set forth.

4. An insulated rail-joint,comprising a plurality of rail-sections and a suitable support for the same, the base of at least one of the rail-sections being cut away to aitord provispecification in the presence of two subscribing witnesses.
