SPECIFICATION forming art of Letters Patent No. 738,862, dated September 15, 1903.

Application filed september 20, 1902. Serial No. 124,193. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE ADAM WEBER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Insulated Joints for Railroad-Rail Sections,

of which the following is a full, clear, and exembodying my improvement, and Fig. 2 is a top view of the same.

A A designate railroad-rail sections of any suitable form arranged in line.

B designates an angle-chair, preferably made of rolled steel and comprising abase l) and an upright 12 preferably strengthened at their junction by means of an outside fillet 17 It may also be provided with an inside fillet bflwhich will still further strengthen the structure O and C designate piecesof packing ma terial or blocks, which may be of wood. They are arranged on opposite sides of the rail-sections and preferably extend across adjacent ends of the same longitudinally, (designated by 0'.) One of these pieces of packing material is arranged intermediate of the upright or bolt plate 12 of the angle-chair B and the webs of the rail-sections A A The other piece of packing material (designated as O isarranged intermediate the other sides of thewebs of the rail-sections, and a metal bar orband, designated as D and which preferably will be made of rolled steel and extends across adjacent ends of the railsections and approximately the length of the said pieces of packing materiahis arranged contiguously thereto. E designates bolts for securing said parts together by passing through said upright of said angle-chair, said pieces of packing material, and said metal bar.

In order to prevent an electric current pass ing from one of the adjacent rail-sections to the other, it is necessary to insulate said sections and the above-mentioned parts, so as to insure a break for the stoppage of the current at at least one point in each electric contacting part or parts, which would otherwise form an electrical connection between the two railsections. My preferred construction for accomplishing this result is as follows: Insulating material is arranged along the entire sur faces of both the upright and base or bridge plate of the angle chair and intermediate not only said upright and the packing con= tiguous thereto, but said base and the base of the rail-sections. Such an insulator is desig natedin the drawings as F and may, as there shown ,extend continuously downwardly along the entire side of the upright and thence along the base of the angle-chair.

The ends of the adjacent rail sections are insulated from each otherby suitable means as, for example, by insulating material K, as shown; but this is unnecessary when the rail ends are separated by an air-space;

The washers E and E of insulating material, arranged intermediate the heads of the bolts and the upright and metal bar, respec tively, and sleeves or bushings P, also of in= sulating material, surrounding the bolts, as shown, throughout that portion of said bolts which pass through said upright and said metal bar, insulate the bolts from both said bar and said upright.

It will be seen that accordingto my construction where all the bolt ends and heads are insulated current cannot pass from rail to rail through either the chair or metal bar with* out passing insulation at two points because of there being insulation between both rail ends and the bar and chair. This double insulation, though preferred, is not, therefore, essential. v

Obviously some features of the invention may be used without other features and may be embodied in Widely-varyin g forms. Therefore, Without enumerating equivalents or lim-- extending across the joint, two insulatinga blocks one betweensaid bolt-plate and the rail ends and the other between said band and the rail ends and both extending across the joint, a plurality of bolts extending through the bolt-plate, insulating-blocks, rail ends, and band, insulating-bushings adapted to in sulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other, substantially as set forth.

2. In an insulated joint for railroad-rail sec tions, the combination of a rail-chair comprising a bridge-plate for supporting the rail ends and a bolt-plate at one side of the Webs of the rail ends, a metal bandv arranged on the other side of the Webs of the rail ends and extending across the joint, packing material between the rail ends and said metal band and between the rail ends and the bolt-plate, bolts extending through the bolt plate, packing material, Webs of the rails and metal band, means for insulating the bolts of at least one of the rail-sectionsfrom the metalband, means for insulating the bolts of at least one of the rail-sections from the bolt-plate, and means for maintaining the rail ends from contact with each other, substantially as set forth.

3. In an insulated joint for railroad-rail sec-- tions, the combination of an angle-chair comprising a base for supporting the rail-sections and an upright at one side of the webs of the rail-sections, a metal bar constructed independently of the angle-chair and arranged on the other side of the Webs of the rail-sections and substantially parallel to the upright of said angle-chair and extending across the joint of the railsections, bolts extending through said angle-chair and said bar for securing those parts together, and insulating material for the bolts, the upright of the angle-chair and the said metal bar for preventing electric communication between the rail-sections, for substantially the purposes set forth.

4. In an insulatedj oint for railroad-rail sections, the combination of an angle-chair comprising a base for supporting the rail-sections and an upright at one side of the webs of the rail-sections, a metal bar constructed independently of the angle-chair and arranged on the other side of the Webs of the rail-sections and extending across the joint of the rail-sections, packing material on each side of the Webs of the rail-sections extending across-the joint of the rail-sections, and arranged between the said upright and said metal bar, bolts for securing the parts together, and insulating material for the bolts forpreventing electric communication between the rail-sections, for substantially the purposes set forth.

5. In a joint for railroad-rail sections, the combination of an angle-chair comprising a base 1" or supporting the rail-sections and an upright at one side of the rail-sections,a metal part constructed independently of the angleehair and arranged on the other side of the Webs of the railsections and substantially parallel to the upright of said angle-chair and backing at each side of the rail-webs, and bolts extending through the upright of said angle-chair and said bar for securin g the parts together, and means for insulating the bolts of at least one of the rail-sections from both the angle-chair and the said metal part, for substantially the purposes set forth.

1 6. In an insulated joint for railroad -rail sections, the combination of an an gle-chair com- 2 prisin g a base for supporting the rail-sections, and an upright at one side of the Webs of the rail-sections, a metal bar constructed independently of the angle-chair and arranged on the other side of the webs of the rail-sections and extending across the joint of the railsections,packing material intermediate of the rail-sections and said metal bar, and bolts for securing the parts together, for substantially the purposes set forth.
