Fig. 15 is poses of illustrating the practical application a similar view showing a different form of of our invention.

It is obvious that the particular form or type of bond isimmaterial so long as it is provided with terminals for application flatwise against the surface to be bonded. For instance, in Fig. 1 we have shown a laminated bond C, having terminal feet D, the laminated body of the bond intermediate the feet being formed into loop shape. In Fig. 2 we have Shown a form of bond the body portion E of which is laminated and formed into substantially U shape and having terminalsF extending transversely across the ends of the body portion. In practice we prefer to form the bond-terminals of solid homogeneous masses, though we do not desire to be limited in this respect. In the form of terminal shown in Figs. 1 and 2 said terminals are of substantially wedge shape in cross-section, as shown in Fig. 3, the outlines orbounding-surfaces of the bond-terminal in cross-section forming substantially a right-angled triangle, with its apex G presented toward and lying adjacent to the tread-surface of the rail and its hypotenuse forming the exterior surface of the terminal and one of its rectangular surfaces lying flatwise against the side surface of the rail-tread. By reason of this construction the bond-terminal presents a knifeedge upwardly-lying against the side surface of the rail-tread and its exterior surface forming in contour a continuation of the surface of the rail to which the bond is applied, thereby avoiding the formation of square shoulders or surfaces for a wheel, hoof, or foot to strike against, whereby the bond may be detached from its engagement with the rail. It is not necessary, however, that the bond-terminal be of triangular shape in crosssection. For instance, a terminal D is shown in cross-section in Fig. 4, wherein the outer surface (indicated at H) is slightly concaved, the terminal, however, presenting a sharpened or knife edge G upwardly toward the treadsurface of the rail; and in Fig. 5 we have shown a terminal D presenting the sharpened or knife edge G along its upper edge, but the outer surface H thereof being convexed; and in Figs. 7 and 10 we have shown a bond-terminal D presenting a sharpened or knife edge G along the upper edge thereof, but beveled, as at H to form the sharpened edge G, the body of the terminal being generally of rectangular shape. In Figs. 8 and 11 we have shown a terminal D beveled to form an upper sharpened edge G and also a lower sharpened or beveled edge G, the outer surface of the bond being beveled both upwardly, as at H and downwardly, as at H, leaving the inner surface of the terminal plane for application to the surface of the rail to be bonded, and this characteristic obtains throughout the various forms of our invention illustrated. In

Fig. 9 we have shown a form of bond-terminal D in which both an upper and a lower sharpened edge G G is formed; but the outer surfaces H H, which produce the sharpened edges G G, are concaved. In Figs. 6, 12, and 13 we have shown another form of bond-terminal D which is plano-convex in cross-section, thereby forming a sharpened upper edge G, as well as a sharpened lower edge G the outer surface H of the terminal being convexed, while the inner surface of the terminal is plane for application against the surface to be bonded. In Figs. 15, 16, and 17 we have shown the plano-convex form of terminal as applied to the terminals F" of the form of bond shown in Fig. 2, the outer surface of the terminal being convexed, while the inner surface is plane, thereby producing a sharpened upper edge G. In Fig. 14 we have shown a terminal F of the form shown in Fig. 2 and oppositely beveled, as in the form shown in Figs. 8 and 11, above described, to produce the sharpened upper edge G and also a sharpened lower edge G. If desired, and as illustrated in Figs. 10, 11, and 14, the ends of the terminals may also be beveled or sharpened, as indicated at J.

It will be observed that in the various forms of terminals illustrated as exemplifications of our invention a flattened inner surface is produced to lie flatwise against the side surface of the rail-tread and that the upper edge of the terminalthat is, the edge presented toward the tread-surface of the rail-"is reduced in thickness to a knife-edge, and these are characteristic features of our invention.

It is obvious that many variations and changes in the details of construction and arrangement would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of our invention. e desire it to be understood, therefore, that our invention is not limited or restricted to the exact details shown and described.

e are aware that it is common practice to bevel the edges of objects to avoid abrupt collision with other relatively moving bodies, and it may have heretofore been proposed to bevel rail-bonds for the purpose of adapting them to their positions of use or to economize the metal; but such is not the equivalent of our invention, nor do we wish to claim the same, because in our invention the beveling of the upper edge of the foot or terminal not only prevents it from coming into abrupt collision with moving bodies, but it causes the terminal or foot to stick more securely to the rail and renders it less liable to be ripped off by a blow applied laterally to the side of the body portion. For. illustration, should the terminal D receive a laterally-directed blow at its lower edge it would exert a tendency to rotate or tip on its lower inner corner, throwing the upper knife-edge outwardly, but the upper edge being considerably reduced in thickness and the rigidity of the terminal thereby greatly impaired it is unable to exert suflicient force at its upper side to rip the thin feather-like edge away from the grasp of the solder. When the terminal once starts to loosen at its upper edge, however, its entire security is destroyed, and it would be thus started. by a blow of the described character if made solid and rigid throughout its vertical extent.

Having now set forth the object and nature of our invention and various constructions embodying the principles thereof, what we claim as new and useful and of our own invention, and desire to secure by Letters Patent, is

1. The combination with a rail having a tread, of a bond provided with a terminal formed with a flattened surface for application against the side surface of the tread of the rail, and being reduced in thickness toward the edge thereof which is presented toward the tread-surface 0f the rail.

2. The combination with a rail having a tread, of a bond provided with a terminal formed with a flattened surface beveled to the surface of the rail at its upper edge and being soldered to the rail.

3. The combination with a rail having a tread, of a rail-bond provided with a terminal formed with a flattened surface at its inner side and soldered to the rail, said terminal being beveled from its lower edge upwardly to the surface of the rail, terminating in a thin knife-edge at its upper edge, and a flexihis body portion at each end of which one of the described terminals is secured.

In witness whereof we have hereunto set our hands, this 16th day of December, 1904:, in the presence of the subscribing witnesses.
