SPECIFICATION forming part of Letters Patent No. 744 834, dated November 24, 1903. Application filed April 15, 1903. Serial No. 152,743. (No model.)

T at whom it ntay 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 Joints, of which the following is a specificat-ion, accompanied by drawings.

My invention relates to railroad-rail joints,

IO but more particularly to that class known as insulated joints. The objects of myinvention are toimprove upon the construction of such joints and increase their efficiency with simplicity of conr5 struction and additional strength of parts.

To these ends myiuvention consists of apparatus for carrying out the above objects embodying the features of construction, combinations of elements, and arrangement of parts, substantially as hereinafter fully described and clailned in this specification and shown in the accompanying drawings, in which Figure 1 is a side view of a rail-joint embodying my invention. Fig. 2 is aplan view of Fig. 1. Fig. 3 is a transverse sectional view taken on the line-X X of Fig. 1.

In the construction of insulated rail-joints it is not always necessary to provide insulating material beneath the bases of both rails, but only beneath one of them, and therefore suitable compensation must be afforded for the other rail, beneath which no insulation is placed, in order to maintain the railsin sur- ;5 face. Suitable blocks or cleats or thickened portions of metal in the form of plates may be provided upon the base of the angle-chair to maintain the rails in surface and alinement; but according to myinvention a compact, strong, and efficient joint is obtained,

while the use of blocks or cleats or thickened portions vof metal upon the rail chair is avoided.

Referring to the drawings, an insulated joint is shown in which the rails A and B,

supported upon the rail-chair O, are of the same weight and height. There is a sheet of insulating material D arranged beneath the base of one of the rails, as B, and in order to compensate for the thickness of the insulating material D in this instance the anglechair is corrugated, as shown, overa portion of the base E. The corrugations F are of sufficieut height above the level of the plane surface of the base E to bring the rails into surface, and at the same time a firm support is provided for the end of the rail, which is not deranged by traffic.

The corrugations F may be formed upon the base of the angle-chair by any suitable means, and they may extend either longitudinally of the chair, as shown, or transversely thereof, as desired. These corrugations may have any suitable or desired size and dimensions to meet the conditions required. I am not to be understood as limiting myself to corrugations of the form shown, for rail-chairs such as shown in my copending applications, Serial Nos. 152,739 and 152,742, filed April 15, 1903, may be used with the insulated joints 7:: described and with other insulated joints.

I have chosen to illustrate one form of insulated joint for carrying out my invention, and I am not to be understood as limiting myself to this particular form of joint. In the form of insulated joint shown it will be seen that suitable insulating filling-blocks K, in this instance of wood, are arranged adjacent the webs of the rails, one of said blocks being arranged between the webs of the rails and the 89 upright of the angle-chair and the other block being arranged between the longitudinallyextending strengthening bar or band L, which may be of metal, and the webs of the rails. Suitable bolts 0 secure the parts of the joint together, and means are provided for insulating the bolts from the upright of the angle-chair and from the strengthening-bar L, suitable insulating-washers P and sleeves Q being provided for that purpose. Means are 0 provided for maintaining the insulation D firmly in position beneath the base of the rail 13, in this instance said insulation being extended upwardly between one of the blocks K and the upright of the angle-chair, so that 5 when the nuts R are tightened the upwardlyextending portion of the insulation is tightly clamped between the block K and the anglechair.

I do not herein claim, broadly, an insulated [o0 rail-joint embodying the strengthening strap or band extending across the joint opposite the upright of the chair, as insulated joints embodying this feature in various forms are claimed in my copending applications, Serial Nos. 63,124 and 63,125, filed June 4, 1901; Serial No. 87,053, filed December 24, 1901;

Serial No. 124,193, filed September 20, 1902,

and Serial No.'133,770,filed December 3, 1902, nor do I herein broadly claim the insulated step-joint disclosed in my copending application, Serial No. 147,613, filed March 13, 1903.

Obviously some features of my invention may be used Without others, and my invention may be embodied in widely varying forms.

Therefore, Without limiting myself to the construction shown and described nor enu merating equivalents, I claim, and desire to secure by Letters Patent, the following:

1. An insulated rail-joint comprising the meeting ends of rails, an angle-chair having a base and an upright, one portion of the base of the angle-chair being provided with corrugations integral with the chair, one of said rails being supported upon the corrugations, and the other of said rails being supported upon a sheet of insulation upon the uncorrugated portion of the base of the chair, fillingblocks arranged along the Webs of the rails, one of said blocks being arranged between the webs of the rails and the upright of the angle-chair,a metallic strengtheningbar or band extending across the joint outside of the other blocks, and bolts for securing the parts of the joint together, said bolts being suit-ably insulated by insulating Washers and sleeves, for substantially the purposes set forth.

2 An insulated rail-joint, comprising the meeting ends of rails and means for supporting said rails in surface consisting of a baseplate having a corrugated portion for one of the rails, means for insulating one of the rails from said base-plate, bolt-plates and means for insulating said bolt-plates from the rails, and insulated bolts for securing the parts of the joint together, for substantially the purposes set forth.

3. An insulated rail-joint, comprising the meeting ends of rails and means for supporting said rails in surface consisting of a baseplate, one portion of its surface being pressed outwardly beyond the remainder for one of the rails, means for insulating one of the rails from the base-plate, and insulated means for maintaining the rails in alinement, for substantially the purposes set forth.

4. An insulated rail-joint, comprising the meeting ends of rails and means for supporting said rails in surface consisting of a railchair having a base and an upright, a portion of the surface of the base being pressed outwardly beyond the remainder of thesurface for one of the rails, insulated means for maintainiug the rails in alinement, and insulated bolts for securing the parts of the joint together, for substantially the purposes set forth.

5. An insulated rail-joint, comprising the meeting ends of rails and means for supporting said rails in surface, consisting of a baseplate, one portion of its surface being pressed outwardly beyond the remainder for one of the rails, means for maintaining the rails in alinement, and means for insulating the rails from each other, for substantially the purposes set forth.

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