"One of the objects of the invention is to provide a joint bar having no rail web or rail flange contact at the center of the joint but having engagement with the underside I of the rail head as well as contact with the head and base fillets of the rail at the center. That is to say, a bar constructed in accordance with the present invention has its central portion formed to fit the underside of the rail head and both the head and base fillets of the rail while the underside of the foot flange of the bar clears the foot flange of the rail at the. center of the joint, and the ends of the bar have clearance from the underside of the rail head but contact with the upper side of the base flange of the rail.

Accordingly, the present invention provides a joint bar having a loading engagement not only with the head and base fillets of the rail at the center of the joint, but also a full bearing engagement with the underside of the rail head while the web of the 13 bar stands entirely free from the web of the rail and the ends of the bar may be placed under tension under pressure of the joint bolts to maintain the loading engagement referred to effective under all track condi- 1 tions. Also, due to the fact that the central part of the bar has engagement with the underside of the rail head while the corresponding central portionon the lower face of the bar is free of the foot flange, but the ends x40 of the bar bear against the inclined upper surfaces of the rail flange, a maximum clamp ing force is exerted against the head fillet of the rail and the underside of the rail head. Another object of the invention is to provide a joint bar having the general characteristics referred to which may be readily rolled in accordance with standard rolling mill practice and which is of substantially uniform section at its medial portion but of Y reduced cross-sectional area at its ends.

With the above and'other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, com- I bin'ation and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a side elevation of a bar'embodying the present improvements.

Figure 2 is a vertical half-sectional view taken on the line'22 of Fig. 1.-

Figure 3 is a vertical half-sectional view taken on the line 3-3 of Fig. 1.

Figure 4 is a horizontal sectional view taken on the line 4-4 of Fig. 1.

Similar reference characters designatecorresponding parts throughout the several figures of the drawings.

According to the embodiment of'the invention shown in the accompanying drawings the rails R and R are connected by a pair of siinilarjoint bars A provided with the bolt holes 1 for receiving the usual joint bolts, not shown. Each oint bar A is preferably of the type conforming tostanda-rd joint bar. practice wherein the web 2 of the bar stands outwardly from the web of the rail thus being entirely free from rail web contact throughout the joint. 7

Referring to the particular features and characteristics of the joint bar A it will be observed that the head 3 of the bar is provided at its central portion with a rail head contacting surface 4 which engages the undersi'des of the heads of the rails R and R and extends beyond the inner bolt holes 1, 1. Also, the head 3 of the baris provided with a head fillet contacting portion -'5 for engaging with the head fillet 6 of the rails, the said portion 5 being coeXtensive'wi'th the rail head contacting surface 4 of the bar at the center thereof. The foot 7 is provided at the central portion thereof withabase fillet bearing rib '8 'for'engagin'g with the base fillet 9 of the rail and the underside of the ffdbt "flange 7 is formed with the clearance 10 which v thereof are vformed'as'indicated atet -an'd 5 so as to avoid contact With the underside of .surfaces11 of the rail bases 12. The-inner the rail head and With' the head fillet'6' of the rails. On the other hand, thefoot 7 of the rail, at the ends thereof, is formed with the rail base flange engaging surfaces 7 for engaging directly with the upper inclined rib portion 8 at the foot of the bar is also formed tohave clearance from the base fillet 9 of the rail.

When the oint barsare applied to the rails the central portions thereof will have a loading engagement with both the underside of the rail head and the upper and lower'flllets G and 9,,thus firmly clamping and aligning the rail ends at the center of the jpint. This engagement is effectively. maintalned underbolt pressure due to the resiliency in the ends ofthebar which are free of any contact with the underside of the rail head and the upper the rail, the under medial surface of said bar having clearance from the upper side of the rail'flange, and the ends of the bar being formed for contactwith the base flange of the rail and for clearance from the base fillet of the rail;

3. A'rail jointbar formed for clearance from the rail Web and having its medial portion formed for contact with the underside of the rail head and thehead andbase fillets of the rail, said bar also being formed for medial clearance from the rail flange and for end contact With the rail flange and end clearance from the head and base fillets of the rail v a 1 p 4 In a railrjoint,therail, and a joint bar having endclearance from the head and the 'Web vof thelrail, end 'contact'with therail flange, medial headcontact with the rail, and medial vclearance from the; rail flange.
