SPECIFICATION forming part of Letters Patent N 0. 770,342, dated September 20, 1904.

Application filed November 13, 1903. Serial No. 181,008. No model.)

To all whom, it may concern:

Be it known that we, GEORGE A. WEBER and PERCY HOLBROOK, citizens of the United States, and residents 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 specification accompanied by drawings.

This invention relates to insulated railjoints; and its objects are to improve upon the strength and efficiency of such joints with simplicity of parts.

Further objects of the invention will here- 5 inafter 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 a joint embodying the invention. Fig. 2 is a 5 transverse sectional view of a joint having a single shoe-angle. Fig. 3 is a sectional plan view of Fig. 1 on the line as a". Fig. 4 shows a modified form of shoe-angle.

Referring to the drawings, A and B rep- 3 resent the meeting ends of rails which in Fig.

1 are supported upon the bases C of the railchairs D, which chairs, as shown in this instance, are provided with the inwardly-bent portions E and the upright portions F, the latter portions forming bolt plates. The chairs, as shown, are provided with fillets or spiking-ribs R, extending from the juncture of the inwardly-turned portion E and the base C of each shoe-angle. These spiking- 4 ribs R are of sufficient length to afford provision for the spiking-holes S, through which the spikes T are driven. These holes could be slots. As shown, the flanges G of the bases of the rails are adapted to extend beneath the inwardly turned or bent portions- E of the chairs, and the base of at least one of the rails is insulated from the chair by means of the insulation H, which may extend up along the upright.

The uprights or bolt-plates F are suitably insulated from the webs of the rails either by insulating-washers-I over the bolts, as shown in Fig. 2, or else by comparatively thin insulating material, as fiber or other suitable material, extending the length of the joint, as shown in Figs. 1 and 3. The uprights F are insulated from the shanks of the bolts K by means of the usual insulating-sleeves L, and insulating-washers O are provided heneath the heads and nuts of the bolts, with metallic washers P outside of the same.

According to the construction described it will be seen that the uprights F or bolt-plates of the shoe-angles are brought close up to the webs of the rails adjacent thereto, being separated therefrom by the comparatively thin insulation J. It will thus be seen that a very strong and compact joint is formed.

In Fig. 2 but one shoe-angle D is used, with an opposing bolt'plate or band S, of metal, opposite the bolt-plate F of the shoe-angle and suitably insulated from the bolts and from the rails, as in Fig. 1. This construction is also efficient and strong.

In the rail-joints shown the modified form of shoe-angle illustrated in Fig. 4 maybe used. In this form there is no spiking-rib or fillet; but the bent portion of the shoe at the juncture between the base and the inwardly-turned portion is slotted to afford spiking facilities.

According to this invention it will be seen that on account of the thin sheet of insulation used for insulating the bolt-plates from the webs of the rails the bolt-plates are thereby brought very close to the rail-webs and are situated between the heads and base-flanges of the rails and wholly inside of the outer edges of the rail-tread that is to say, the bolt-plates are inside of vertical planes passing through the outer edges of the flanges of the rail-heads. The advantage of this construction resides in the fact that the bolt-plates which form the trusses of a bridge are practically a part of the rail-webs and are not, as in ordinary constructions, situated at a considerable distance from the rail-webs.

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,

We claim, and desire to obtain by Letters Patent, the following:

1. An insulated joint, comprising the meeting ends of rails, a shoe-angle having a base, an inwardly-turned portion, and an upright or bolt-plate extending therefrom, with a spiking-rib or fillet at the juncture of the inwardly-turned portion and the base, a side bar or bolt-plate at the other'side of the joint opposite the upright of the shoe-angle, suitable comparatively thin sheet insulation for insulating the upright of the shoe-angle and bar from the webs of the rails, said boltplates being thereby situated between the heads and base-flanges of the rails and wholly inside of the outer edges of the rail-tread, bolts for securing the parts of the joint together, and means for insulating said bolts from the shoe-angle and bar, for substantially the purposes set forth.

2. An insulated rail-joint, comprising the meeting ends of rails, shoe-angles each comprising a base, an inwardly-turned portion, and an upright or bolt-plate extending therefrom, with a spiking-ribor fillet at the juncture of the inwardly-turned portion and the base, the inwardly-turned portions of the shoe-angles extending over the flanges of the bases of the rails, means for insulating the base of at least one of the rails from the shoeangles, suitable comparatively thin sheet in- 4 sulation for insulating the uprights of the chairs from the rails, said uprights or boltplates being thereby situated between the heads and base-flanges of the rails and wholly inside of the outer edges of the rail-tread, bolts for securing the parts of the joint together, and means for insulating said bolts from the shoe-angles, for substantially the purposes set forth.

3. An insulated joint, comprising the meeting ends of rails, a shoe-angle having a base, an inwardly-turned portion, and an upright or bolt-plate extending therefrom, a side bar or bolt-plate at the other side of the joint 0pposite the upright of the shoe-angle, suitable comparatively thin sheet insulation for insulating the upright of the shoe-angle and bar from the webs of the rails, said bolt-plates being thereby situated between the heads and base-flanges of the rails and wholly inside of the outer edges of the rail-tread, bolts for securing the parts of the joint together, and means for insulating said bolts from the shoeangle and bar, for substantially the purposes set forth.

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