Application filed January 29, 1906. Serial No. 298,417.

`To a/Z whom it may concern:

,Be it known that I, MILES WIL'BERT l/VIL- LIAMs, a citizen of the United States, residing at Sharon, in the county of Mercerand State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joint-Base 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 in the art to which it appertains to make and use the same.

-For rail-joints I have' produced a novel bondin device whereby the meeting ends of the rais are firmly connected and lsecured and a joining maintained bya wedge action of the bonding device drawing the rail ends together andA bracing them against-sidewise displacement. The bonding device crosses the rail-joint and is secured in grooves having vertlcal inclined shoulders in the base of each rail, and its construction is .such that it forms-a duplex Wed e, and for that purpose each end has a shoulgdered and a wedge form acting with a compoundffunction on each rail-that is to say, drawing the rail en ds together and preventing their separation-the object being to dispense with the bolts employed to fasten the rail ends, the chairs, and fish-plates together. In combination with the duplex-wed e bond a box-chair is employed to hold t e rail ends down and laterally, while the wedge-bond holds them together, making a smooth-tread joint and preventingljar to the passing train. for it is a distinguis Ing feature of the duplex-wedge bond that it causes the weight of the train on either end of the joint to act to draw and hold the rail ends together in crossing the joint.

The accompanying drawings illustrate my invention, and in whichy Figure 1 shows the rail ends invertedand a base-groove in each terminating in a vertical socket in the web. Fig. 2 is a tudinal section of the rail-joint, its bonding device, and joint-supporting chair. Fig. 3 is a horizontal section of the rail-joint, bolnding lig. 4 shows .the bonding device In side and end views. Fig. v5 is a vertical cross-section of the rail-joint, its bonding device, and jointsup ortin chair.

T e we of each rail end has avertical base-groove 1, open at the end of the rail and terminating in a vertical socket 2 within the web. This socket joins the groove on each vertical longiside by a vertical shoulder 3, Fig. 3, which stands inclining upward from the base of the rail and away from its end, and the socket preferably tapers from its base to its upper 6o end. Each groove, with its terminal socket, extends about three inches within the web and terminates in the web at the base of the rail-head. The bonding device'consists of a web 4, adapted vto fit the -groove in each railweb and therefore crosses the rail-joint and has an abutment 5 at each end, which partially iills the end sockets of the web-grooves, each abutment forming-a shoulder, inclining upward from the base toward theend of the web, so that it has a wedge action on the shoulders of the socket of each rail-web, the action of which in inserting the bonding device in the grooves is to draw and secure the rail ends' together, the wedge action being such as to draw the joint tighter under the weight of the moving train. The web-abutments and the groove-shouldersv afford security against the endwise separation of the rails,` While the bond-weband its end abutments aord securityagainst lateral se aration of the rails. Moreover, the wedge orm of the bond-abutments provides a firm connection for the rail ends, and as aiding in this function the web ofthe bond is made of wed e form in cross-section, and it will be noted t iat the base of the bonding device is on a plane with= the base of the rail-flan es. The chair is ofthe f 0X type, having its rail side braces or fish-plates 7 integral with thebase-plate 8, the ends of which project beyond the ends of the side braces and are formed with depending flanges 9, which iit against and are spiked to the opposite sides ot the cross-tie, While each side edge of the projecting ends of the base-plate has a notch or recess l0 to receive spikes 11, driven into the cross-tie, so that the chair is fastened to the rail-flanges and to the cross-tie both endwise and sidewise. Openings 12 may be made in the side edges of the braces to receive spikes 13, driven into the cross-tie, and these` several means of securing the chair to the rail may be used together, rendering the boxchair a iirm and durable fixture to the crosstie. Looking at Fig. 2 the lower edge of the bondin0F device is seen resting u on the baselate oi:j the box-chair, and as t e web of the bonding device is wedge-shaped in cross-section and its end abutments form wedges the I 1c weight of the rails will constantly tend to force the web and its abutments into the rail lOO IOS

grooves and sockets, while the weight upon the rails keeps them down on the bond. Obviously the rail-sockets and the bondingabutments may be of any suitable form so long as thcy are adapted to coact in awedge l action for drawing the rail ends togther.

vertical socket within the I claim* 1. In a raiLjoint, the meeting ends havinvr each a vertical base-groove open at the en of the rail, and terminating in an enlarged web, tapering upward from the base of the rail and forming a vertical shoulder on each side of the groove inclining upward from the base and from the end of the rail, and a bonding device formed of a web fitting the rail-grooves and having at each end a vertical abutment fitting the tapering sockets of the grooves, each abutment having a shoulder on each side of the web abutting the inclined shoulders of the railgrooves, whereby the bonding device is caused to have a wedge action on each rail to draw and hold them together at the oint.

l2. In a rail-joint the meeting ends having each a vertical base-groove open at the end of the rail, terminating in an enlarged vertical socket within the web and having a vertical shoulder on each side of the groove, and a bonding device formed of a web fitting the rail-grooves and having at each end an abutment .fitting the vertical sockets of the grooves and having a shoulder each side of the web adapted to coact with the shoulders ofthe rail-grooves to cause a Wedge action to draw and hold the rail ends togethei` at the joint.

3. In a rail-joint the meeting ends having each a vertical base-groove open at the end of the rail and terminating in an enlarged vertical socket within the Web formi-ng a ver# ltical shoulder on each side of the groove, a bonding device formed of a web having at each end an abutment fitting the vertical sockets of the grooves and having a shoulder on each side ofthe web, the said shouldersef the grooves and of the adacpted to have a wedge action to draw and vertical wedge-formed shoulder on each side of the groove, a bonding device formed, ofa vertica web fitting the rail-grooves and having at each end a Wedge-formed abutment fittingthe vertical wedge-formed sockets of the grooves, and a base box-chair having its ends turned down and spiked to the opposite sides ofthe cross-tie and otherwise spiked thereto and to the rail-flanges.

5. In a rail-joint, the meeting ends havin each a verticallJase-groove open at the end of the rail, terminating in an enlarged vertical socket Within the web and forming a vertical shoulder on each side ofthe groove, and a bonding-web fitting the railrooves and having at each end a vertical a utment fitting the sockets of the grooves, each abutment having a shoulder on each side of the web abutting the shoulders of the railgrooves and adapted to coact with them in causin a wedge action drawing and holding the rai s at the'joint, lin combination with a box-chair supporting the rails `laterally, an means for fastening the chair endwse, sidewise and verticallly.

In .testimony whereof I have signed my bonding-abutments the rails together and the grooves andY name to this specification in the presence of two subscribing Witnesses.
