INSULATED RAI L-JOINT.

SPECIFICATION forming part of Letters Patent No. 772,010, dated October 11, 1904. Application filed November 23,1903. Serial No. 182,268. (No model.')

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 Rail- Joints, of which the following is a specification accompaniedby drawings.

This invention relates to rail joints, but more particularly to that class known as. insulated joints, having suitable insulation provided for insulating one rail from the other.

The objects of this invention are to improve upon the construction of such joints and simplify them, while at the same time affording high efficiency of insulation.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of an insulated joint for carrying out 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 transverse sectional view of an insulated joint embodying the invention, having two rail-chairs. Fig. 2 is a transverse sectional view of a joint having one rail-chair. Fig. 3 is a plan view taken on the line w of Fig. 2, showing insulating-washers between the metallic filling-pieces and the uprights of the chair. Fig. 4 is a longitudinal side view showing insulation under one of the rails only. Fig. 5 is a transverse sectional view of a joint having one rail-chair and showing a different mode of insulating the metallic filling-pieces. Fig. 6 is a transverse sectional view showing an insulated bar between the filling-pieces and the webs of the rails. Figs. 7 and 8 are sectional views of joints having filling-pieces of insulating material, as wood. Fig. 9 is a sectional view of a joint in which the fillingpieces are in the form of straps of insulating material, as wood. Fig. 10 is a plan view of Fig. 9.

Referring to the drawings, A and B represent the meeting ends of rails to be insulated from each other, and C represents rail-chairs at each side of the joint, each having a base D, an upright E, and a spiking rib or fillet F. Beneath the base of at least one of the rails is arranged insulation G to insulate said rail from the chairs. In Fig. 4 the insulation G is shown beneath one of the rails, while the other rail is supported upon a block H.

Between the webs of the rails and the uprights of the chairs are arranged the fillingpieces I, of any suitable material, as metal, or insulating material, as wood, in this instance they being shown of metal in the form of spools.

In Fig. 1 the insulation G is extended upward along the inner faces of the uprights E to insulate the metallic filling-pieces I from the uprights. As shown in the drawings, the filling-pieces I bear directly against the webs of the rails in Figs. 1 and 2, which permits the uprights of the chairs to be brought as close as possible to the rails.

In I Fig. 5 another mode of insulation is shown in which a strip of insulating material or insulating-washers J are arranged between the metallic filling-pieces and the webs of the rails, while said filling-pieces are permitted to bear directly against the inside faces of the uprights of the chairs. Insulating-sleeves K are provided for preventing contact between the filling-pieces I and the bolts L. The bolts L for securing the parts of the joint together are insulated from the uprights of the chairs in this instance by the usual insulating-sleeves K and washers O. Instead of using insulating-washers J between the filling-pieces I and the webs of the rails a continuous insulating-strip may be used.

In Fig. 2 a metal bar, band, or strap I is arranged at the side of the joint opposite the upright of the chair, this strap being suitably insulated from the bolts by the sleeves K and washers O and being further insulated from the webs of the rails by insulating-washers Q, arranged at each bolt-hole.

In Fig. 6 a short insulated bar R, of metal, is shown between the metallic filling-pieces and the webs of the rails for strengthening purposes. This bar need not extend the entire length of the joint and, as shown, is insulated from the Webs of the rails either by a continuous strip of insulation or by insulatingwashers Q.

In Figs. 7 and 8 the filling-pieces are of insulating material, as wood, or any other suitable insulation, and the insulation between them and the railsand chairs is omitted.

In Figs. 9 and 10 the filling-pieces are in the form of straps 25 of insulating material of any suitable character, as wood.

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

Therefore, withoutlimiting the invention to the construction shown and described nor enumerating equivalents, I claim, and desire to secure by Letters Patent, the following:

1. An insulated rail-joint, comprising the meeting ends of rails, a rail-chair having an upright, the webs of the rails and the said upright forming opposed portions of the joint, metallic filling-pieces in the form of thimbles or sleeves arranged between said portions and bearing directly against one portion but insulated from the other portion, bolts for securing the parts of the joint together, and means for insulating one rail from the other, for substantially the purposes set forth.

2. An insulated rail-joint, comprising the meeting ends of rails, a rail-chair having an upright, metallic filling-pieces in the form of thimbles or sleeves between the rail-webs and said upright, bearing directly against the railwebs but insulated from the upright, bolts for securing the parts of the joint together, and means for insulating one rail from the other, for substantially the purposes set forth.

3. An insulated rail-joint, comprising the meeting ends of rails, rail-chairs one at each side of the joint, the rail-webs and the uprights of the chairs forming opposed portions, the uprights being opposed to the rail-webs, metallic filling-pieces in the form of thimbles or sleeves between said opposed portions at each side of the joint, and insulated from one opposed portion but bearing directly against the other opposed portion, between which the said pieces are arranged, bolts for securing the parts of the joint together, and means for insulating one rail from the other, for substantially the purposes set forth.

4:. An insulated rail-joint, comprising the meeting ends of rails, a rail-chair at each side of the joint, metallic filling-pieces in the form of thimbles or sleeves between the Webs of the rails and the uprights of the chairs, said filling-pieces being insulated from the said uprights, but bearing directly against the railwebs, bolts for securing the parts of the joint together, and means for insulating one rail from the other, for substantially the purposes set forth.

5. An insulated rail-joint, comprising the meeting ends of rails, a rail-chair, metallic filling-pieces between the webs of the rails and the upright of the chair, a metal bar or band at the opposite side of the joint, bolts for securing the parts of the joint together, insulating-washers for insulating said metal bar or band from the rail-webs, said washers being arranged between the band and the railwebs,and further suitable insulation for breaking the electric continuity of the rails, for substantially the purposes set forth.

6. An insulated rail-joint, comprising the meeting ends of rails, a rail-chair, suitable means arranged between the webs of the rails and the upright of the chair for maintaining the rails in alinement, a metal bar or band at the opposite side of the joint, insulated from the webs of the rails by insulating-washers arranged between said band and the rail-webs,

bolts for securing the parts of the joint together, and further suitable insulation for insulating one rail from the other, for substantially the purposes set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE A. WEBER.
