INSULATED JOINT FOR RAILROAD-RAIL SECTIONS.

SPECIFICATION forming part of Letters Patent No. 772,008, dated October 11, 1904,

Application filed June 4, 1901.

To all whom it may concern:

Be it known that I, GEORGE ADAMINEBER, of Stamford, county of Fairfield, State of Connecticut, have invented a new and useful Improvement in Insulated J oints'for Railroad- Rail Sections, of which the following is a specification.

This invention relates to insulated railjoints; and its objects are to improve upon the construction of such joints and increase their strength and eificiency.

Further objects of the invention are to secure a firm splice between the rails with high insulating qualities.

Other 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 having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings.

. In the accompanying drawings, Figure l is a transverse section of arailroad-rail joint embodying my improvement. Fig. 2 is a top view of the same, partly in section. Fig. 3 is an elevation of one side. Fig. 4 is an elevation of the other side. Fig. 5 is a transverse section ofarailroad-railjoint embodying my improvement with some slight modifications of form. Fig. 6 is a top view of the same, partly in section. Fig. 3 not only represents one side of the railroad-rail joint illustrated by Figs. 1 to 4, inclusive, but also one side of the modified form of railroad-joint illustrated by Figs. 5 and 6. Fig. 7 is an elevation of the opposite side of the last-named railroad-rail joint. Fig. 8 is a transverse section of a railroad-rail joint embodying my improvement with some slight modifications of form. Fig. 7 is an elevation of one side of this joint which is illustrated by Fig. 8. Fig. 9- is an elevation of the other side of the joint illustrated by Fig. 8. Fig. 10 is a section, taken transversely to the length of a joint, of certain parts used in the joints of all the preceding figures for insulating a Serial No. 63,124. (No model.)

bolt. Fig. 11 is a similar View of the same parts with some of them detached from others. Fig. 12 is a transverse section of a railroadrail section embodying my improvement and modified as to the insulation of the bolt. Fig. 13 is a perspective view of a strip of insulating material used in my joints. Fig. 14 is a perspective view of a strip of insulating material of modified form.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1 to 4, inclusive, A A designate railroad-rail sections arranged end to end. They may be of any suitable form.

B B designate two angle chairs or shoes having spike-plates and preferably made of rolled steel. Each angle-chair comprises a base or bridge plate I) and an upright or boltplate 6 preferably strengthened at their j unction by means of an outside fillet b and, if desirable, also by an inside fillet 5*. The angle-chairs are provided with spike-receiving recesses b and openings 5, as indicated in Figs. 2, 3, 4, and 6.

C C are bars constituting plates for bolting the rail-joint together, preferably made of steel, arranged on opposite sides of the rail-sections and between them and the uprights of the chairs B B D D designate strips or long thin blocks of insulating material arranged on opposite sides of the webs of the rail-sections and preferably having their edges bent downwardly above the bases and upwardly beneath the heads of the rail-sections. v

E E designate strips of insulating material extending along the bases of the anglechairs and up against the inner sides of the uprights of the angle-chairs. Preferably they will extend up to the top edge of these uprights.

The angle-chairs B E the bars C C, the strips of insulating material D D and the strips of insulating material E E extend the whole length of the joint and lap a considerable length of the adjacent ends of the railsections A A Bolts F secure the .parts together, and of them any suitable number may be used. Sur-.

rounding each bolt intermediate of the uprights of the angle-chairs B B and the bars C C are thimbles or sleeves G G, which may be made of castmetal, preferably steel. They constitute fillingpieces. Intermediate of them and the bars C C are washers H H of insulating material. Outside the uprights of the angle-chairs B B washers I 1 of insulating material, surround the bolts, and outside of these washers of insulating material metal washers J" J surround the bolts. Surrounding the bolts F inside the uprights of the anglechairs B B are bushings K K and these have fitted to them the washers I I and also the washers J J Preferably the bushings will have inside them thin steel sleeves L, with outwardly-turned flanges Z at the outer ends. It will be also advantageous to surround the bushings with steel collars M at one side of the washers I I and to provide these collars with flanges m, bearing against the washers I 1 Thus the bushings K K and the washers I I will be prevented by their metallic armor from injury through abrasion caused by the turning of the bolts.

All the insulating material which I have mentioned will preferably be vulcanized fiber.

The insulating-strips E E for the sake of economy may have their upright portions cut away, as shown in Fig. 141, or like the piece E", as shown in Fig. 13.

In Figs. 5 to 7, inclusive, I have shown the same combination of parts already explained, excepting that the angle-chair B with its appurtenant strip of insulating material E thimbles G and washer H have been omitted and bolts of a shorter size have been substituted for the long bolts.

In Figs. 8 and 9 I have shown the same omissions as in Figs. 5 to 7, and I have also be close to the bar C.

In Fig. 12 I have shown substantially the same construction as in Figs. 5 to 7 but have also shown a modification consisting in the employment of a single bushing K, extending the whole length of the bolts between their heads and nuts, and inside such bushing is a sleeve, preferably of steel, L, which extends almost the whole length of the bushing, but not quite to either of its ends. I have indicated by dotted lines in Fig. 12 that instead of these long bushings short pieces may be employed-as, for instance, two short bushings Z Z, extending through the uprights of the shoes and adjacent parts, and a third short bushing Z through the web of the rail-section.

It will be observed that in all the examples of my invention I have provided for adequate insulation Without weakening the rail-sections by any unusual perforations.

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 constructions shown and described nor enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:
