CORPORATION or NEW JERSEY RAIL BOND Application filed January 29, 1927. Serial No. 164,488.

My invention relates to rail bonds and to that class of rail bonds intended for application to the rail by welding.

The object of my invention is to provide 5 a bond which is simple, cheap and economical in manufacture and which is easy and economical in application, and which is high- 1y eflicient, both mechanically and electrically.

My invention resides in the new and novel construction, combination and relation of the various parts herein disclosed and shown in the accompanying drawing.

In the drawing:

Fig. 1 is a top plan view of my invention.

Fig. 2 is a side view of Fig. 1.

Fig. 3 is a rear view of one of the terminals.

Fig. 4 is a view of one terminal taken on 20the line 4'4 of Fig. 1.

Fig. 5 is a view in partial section of the bond terminal positioned on a rail base ready for attachment.

Fig. 6 is a view of a terminal similar to but before the cables have been attached thereto.

In the preferred embodiment of my invention I employ two main parts, namely; a body member which is composed of one or terminal members 2 secured to the ends of the body member or members. The body portion is preferably composed of stranded copper cable and the terminal members are composed of ferrous material, such as drop forging of steel, malleable iron casting or sheet steel formed up into the required shape. The terminal members may, however, be made of a copper base casting or of forged copper, but the ferrous terminals are preferable, as I find that the welding metal used in attaching the bonds tothe rails forms a stronger mechanical union with steel or iron than it does with a copper or copper alloy terminal.-

The attaching metal may be of pure copper, copper alloy, such as copper and tin, copper and aluminum, copper. and zinc, etc., and these may contain a fiuxing material, such as phosphorous, manganese, silicon, etc.

The terminal member comprises an upstanding wall 3 positioned on three sides of the terminal and so arranged, when applied to the rail base, to form with the vertical edge thereof a receptacle closed on the four sides. Projecting from the ends of the wall 3 are lugs 4 arranged to overlap and rest upon the upper surface of the rail base. Projecting from the terminal and forming a part thereof is a sleeve portion 5 provided with passages 6 arranged in pairs and each passage 6 adapted to receive a body member 1. Each pair of passages might be said to constitute a duplex passage, for the reason that the two passages 6, which form a pair, are not entirely separated, but are open along their adjacent side.

In the construction shown in the drawing,

there are shown two pair or two duplex passages separated by a. partition 7 This partition tends to join the upper and lower walls of the projecting member 5 and prevent them spreading where there are two or more duplex passages used, thereby giving a construction in which the body members are securely gripped and held.

The passages 6 are originally made distorted, as shown in Fig. 6, in order towiden the sameto receive the ends of the body members, and after the members have been posi tioned within the passages 6 the walls are squeezed together and into close engagement with the body members, thereby securing a mechanical grip upon the body members, as shown in Fig. 4.

Projecting from themember 5 is a member 8, which is adapted to engage the lower face of the base of the rail, thereby assisting in positioning the bond on the rail before secured thereto by welding. The lugs 4: and 8 may be made to engage and grip'the rail base rather snugly or they may be so constructed as to form a loosehold upon the rail base, as in either casetheir intent is to temporarily hold the bond in place until welded. The lugs l, however, perform an additional function, in that in combination with the upper surface of the railthey form a receptacle for the welding metal and permit an increased area of attachment between the welding metal and the rail, namely; the vertical and upper surfaces of the rail base within the confines of the wall 3 and lugs 4-.

I prefer to form the projecting portion 5 with its axis X disposed at an acute angle to the lower surface of the rail base or line Y and projecting in a direction to underlie the base of the rail, as this then throws the body members 1 underneath the base of the rail, where they are protected from mechanical injury due to moving objects, and are not so easily gotten at by thieves in attempting to remove the bonds from the rail, as the most common way of removing the bonds is to place a lever in the loop of the bond and to pry it ofi the rail.

When the members 4 and 8 engage the base tightly, they assist materially in holding the bond in place against malicious removal when attempted.

The ends of the body members project within the receptacle referred to, and when the receptacle is filled with molten metal, it will molecularly unite not only with the end of the body member 1, but with the inner surfaces of the walls 3 and 4 and the surfaces of the rail base within the confines of the receptacle. The welding metal will, therefore, unite the said parts each to the other, both mechanically and electrically, but, as the bond member is rigidly and mechanically held to the terminal by means of the portion 5, the joint between the copper body 1 and the attaching metal is doubly assured. As already pointed out, the joint between the copper, made by fusing, is likely to be more or less porous, and, therefore, Weak mechanically, but with the construction shown there is no strain upon the joint between the body memher and the welding metal, for the reason that the terminal securely grips the body member and the welding metal is merely united to the terminal member.

The fact that the terminal member is of steel does not detract from the electrical efficiency of the joint, for the reason that the body member is united to the rail through the medium of a copper base metal, which is molecularly united to both the body member and the rail and is of sufficient carrying capacity for the purpose.

There are, of course, modifications which can be made from those shown, and Wlll readily suggest themselves to those skilled in the art, therefore, I do not wish to be limited other than by my claims.

I claim: 1. A rail bond comprising a body member and a metalhc terminal member secured together, the terminal member consisting of an upstanding wall surrounding the exposed face of the body member on substantially three sides, projections from the ends of the wall to overhang the upper surface of the rail base and form therewith a receptacle to catch, support and retain welding metal in the molten state to unite the body, terminal and rail each to the other, a sleeve portion surrounding and gripping the end of the body leaving the end face exposed within the confines of the wall and holding the axis of the gripped portion of the body member at an acute angle to the plane of the lower surface of the rail base, the said sleeve projecting towards and underneath the rail base and means on the sleeve to engage the lower face of the rail base.
