RAIL-BOND.

SPECIFICATION forming part of Letters Patent No. 583,902, dated June 8, 1897.

Application filed March 19, 1897. Serial No. 628,299. (No model.)

To all whom it may concern:

Be it known that we, SAMUEL H. HARRING- TON, residiu g at New York, NY, and GEORGE E. SOMERS, residing at Bridgeport, Connectiout, citizens of the United States, have invented a new and useful Improvement in Rail-Bonds, of which the following is a specification.

Our invention is designed to facilitate the securing of a rail-bond in a hole drilled at an acute angle in a rail. is designed to simplify and cheapen bonds made for this purpose.

In the accompanying drawings, Figure 1 shows in elevation a rail-bond provided with our device. Fig. 2, in perspective, shows the essential portion of our device detached from the rest.

A designates a rail having a hole a at an acute angle with its surface; B, a bond end having a cylindrio portion 1) and a shoulder b; C, a sleeve having one end 0 diagonal of its length.

lhe same letters refer to like parts in both views.

In the example of our invention illustrated in the drawings the web of the rail A is drilled at a in a slanting directioni. e., at other than a right angle to its surface. The end B of the rail-bond is cylindric, its body 17 being of a size to fit snugly in the hole a. Above the body I) is a shoulder 1), adapted, if the bond were used in a hole drilled at a right angle with the web, to bear against the web and to act with the clench formed at the opposite side of the web by swaging the free end of the bodyb to hold the bond in the rail. This has heretofore been a customary way of making and securing rail-bonds, and we have illustrated it in dotted lines in Fig. 1 of the drawings.

In full lines in Fig. 1 we have shown a sleeve 0 of an internal diameter to fit snugly on the body I) of the bond end B. ()ne end a of the sleeve G is out diagonally of its length, as clearly shown in Fig. 2 of the drawings. The squarelycut end of the sleeve bears against the shoulder h of the bond end, while the diagonal end 0 bears against the web of the rail and acts with the clench at the free end of the bond to secure the bond to the rail and to increase the contactsurface.

In experimenting with a machine for drilling rail webs or bases at an angle other than a right angle with their surfaces a bond was first used the ends of which had an integral angular shoulder swaged on them. This is found in practiceboth expensive and unsatisfactory. It is much cheaper to form the cylindric bond end with the ordinary shoulder and to apply thereto the sleeve herein described. The sleeve may well be made from ordinary tubing by sawing it diagonally into lengths sufficient to make two sleeves, then separating these by an ordinary crossout.

It is understood that our diagonal sleeve may be used with a bond formed of a single rod or of a cable, with one in which the bond end is milled to form a body and a shoulder, or with one in which a separate ferrule is used-i. e., that the form of bond used forms no part of our invention or any limit to the use of our device.

What We claim as our invention, and wish to secure by Letters Patent, is as follows:

1. In combination a rail-bond having a shoulder near its end and a separate sleeve adapted to slip over said end and to bear against said shoulder, one end of said sleeve being diagonal of its axis, substantially as described.

2. In combination a rail-bond consisting of a connecting portion and a shouldered end and a separate sleeve adapted to slip over said end and to bear against said shoulder, one end of said sleeve being diagonal of its axis, substantially as described. g
