JAMES G. HALLAS, OF WATER-BURY, CONNECTICUT, ASSIGNOR TO THE BENE- DICT & BURNHAM MANUFACTURING COMPANY, OF SAME PLACE.

ELECILRIC RAIL-BOND.

SPECIFICATION forming part of Letters Patent No. 523,278, dated July 17, 1894.

I Application filed May 1, 1894. Serial No. 509.705- (No model.) I

To 00% whom it may concern.-

Be it known that I, JAMES G. HALLAS, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Electric Rail- Bonds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled IO in the art to which it appertains to make and use the same.

My invention has for its object to provide a bond for the rails of electric railroads which shall be inexpensive to produce and which shall be so constructed as to expand and contract with the expansion and contraction of the rails andwhich shall have sufficient spring quality to permit it to yield should the rails be unevenly laid or become loosened in use and furthermore to prevent the metal of the bond from becoming crystallized fromthe continual pounding of the wheels of the cars. With these ends in view I have devised the novel electric rail bond which, I will now describe referring by numbers to the accompanying drawings, forming part of this specification, in which- Figures 1 and 2 are elevations, and Fig. 3 is a plan view illustrating slightly diiferent 3o modes in which I have carried my invention sence of my invention, the gist of which consists in providing the bonds with coils so as to give sufficient resiliency to the bond to give it durability in use by permitting the bond to yield with the expansion and contraction of the rails and by preventing crystallization of the bond itself.

In Fig. 1 Theme shown the bond as provided with a single coil lying in a plane transverse to the plane of the bond.

In Fig. 2 the bond is shown as providedv with a single coil which lies substantially in the longitudinal plane of the bond and in Fig. 3 I have shown the bond as provided with coils both in the transverse and horizontal planes and in the transverse plane have shown two coils instead of one coil as in Fig. 1. Near the ends of the bond they are bent upward then outward again the ends 3 thereof being turned upward at right angles thereby forming angular shoulders at which in attaching are set up, close against the under sides of the rails the ends being passed through holes in the rails and headed In testimony whereofI affix my signature in presence of two witnesses.
