Other objects and desirable features of my invention will be hereinafter pointed out. 1 Figure 1 of the drawings is a side eleva- .tional new of a rail-joint constructed in accordance with my invention, the inside member of the joint being broken away and one of the rails being removed so as to more clearly illustrate the construction of the inner face of the outside member of the joint;

Fig. ,2 is a top plan view of the joint partly "rails and lap I in horizontal section; Fig. 3 is an end elevational view of the joint; Fig. 4 is a vertical sectional view taken on approximately the line l-4 of Fig. 1; Fig. ti-onal view illustrating a slight modificat on of my invention; Fig. 6 is a side elevational view similar to Fig. 1 showing an other modification; Fig- 7 1s a top plan view partly in horizontal section of the rail-joint shown in Fig.0; Fig. 8 is an end elevational view of sai oint; and Fig. 9 is a vertical cross sectional view taken on the line 9--9 of F ig. 6.

Referring to Figs. 1 to 4, inclusive, of the drawings which illustrate one form of my invention, A and B designate the two members of the joint that embrace the rails, the m'emberA being arranged on the outside of the rails and the member B on the inside or gage-side of the rails. Both of said memhere have vertically disposed webs 1 that extend practically parallel to the webs of the rails,'and portions 2'Which lap over the base flanges of the rails, the members A and B being preferably reinforced and strengthened by means of horizontally disposed ribs Another object is to provide arail joint or thickened portions 3 which are spaced 5 1s an end elevafar enough below the under side of the heads of the rails at the ends of the joint to permit the railsto deflect slightly at the ends of the joint when a load passes over the joint, as Patent No. 1,013,613, dated January 2,1912. In the form ofmy invention illustrated in Figs. 1 to 4., inclusive, the outside member 7 A of ,the joint is provided at its upper edge -with a wheel-supporting member 4 of similar design to the wheel-supporting member of the joint described in my prior Patent No. 1,013,613, above-referred to.

In the rail-joint herein shown the railsu-pporting portion of the joint is formed by. two cooperating parts 5 and 5 on the members A and B, respectively, of the joint,

said parts 5 and 5 consisting of base plates arranged in the same horizontal plane and clearly described in my prior provided at approximately the center of the joint with flat surfaces 6 of relatively great area on which the .end portions of the base flanges of the rails rest, and inclined surfaces 7 that slope downwardly in opposite directions from the fiat horizontal rail-bearing surfaces 6 so as to prevent. the; base flanges of the rails from normally resting on the end portions of the rail-supporting supporting parts 0 parts of the joint. By forming'the joint in this manner, namely, providing flat ra lsupporting surfaces of relatlvely great area at the center of the joint on which only the .end portions of the abutting rails rest and portions of the railthe joint normally spaced away slightly from the base flanges of the rails, I practically eliminate reverse strains and distribute the load to the ties on which the joint rests without making a fulcrum of the ties and without causing a pumping up and down of the ties due to fulcruming. r

The portions 2. of the members A and B are so designed that they bear upon the top faces of the base flanges of the rails at the center of the joint and thus securely clamp the end portions of the rails in operative position upon the flat rail-bearing surfaces 6 having the remainin at the center of the joint, as shown in Fig. 4.- The members A and B are held in position.

and in engagement with the rails by means of bolts 8 that pass transversely through the webs of said members and through the webs of the rails, and as the portions 2 of said member are spaced just far enough away from the rail-supporting parts 5 and 5 at the center of the joint to receive the base flanges of the rails, the rails will be held securely against vertical and lateral movement at the center of the joint. The rails can deflect downwardly slightly with relation to the members A and B at the ends of the joint, as previously stated, and in order to prevent the rails from becoming kinked or bent vertically when the end bolts of the joint are tightened, I have provided the members A and B with spacing ribs or stops 9, as shown in Figs. 2, 3 and 4, which are so proportioned and disposed that they limit the inward movement of the members A and B with relation to the rails and thus prevent the portions 2 of said members from exerting sufficient downward pressure on the base flanges of the rails when the end bolts of the joint are tightened to cause the rails to kink or bend vertically at the ends of the joint. In other words, the members A and B are provided on their inner faces with devices which are so designed that they prevent said members from being drawn inwardly at the ends of the joint far enough to cause the portions 2 of said members to bend the base flanges of the rails downwardly and thus kink the .rails vertically when the end bolts of the joint are tightened. I have herein shown the stops or ribs 9 as extending the entire length of the members A and B but this is only for convenience in manufacturing the joint when the joint is rolled as it is only essential that the stops 9 be arranged at the ends of the joint. I prefer to design the stops 9 in such a manner that they do not contact with the vertical webs stops will not bite of the rails at the center of the joint, and also round off the ends of said stops at 9, as shown in Fig. '2, so that the ends of said into the webs of the rails or nick the rails. By forming the rail-joint in this manner I obtain an exceptionally strong and serviceable structure as the joint comprises two girders arranged parallel to the rails on opposite sides of the rails, and provided with cooperating rail-supporting portions which are so designed that the rails can deflect downwardly slightly at .the ends of the joint when a load passes over the joint, thereby practically eliminating reverse strains and distributing the load to.the ties on which the joint rests without causing the tiesto pump up and down. The rail-supporting portion of the joint may be formed lighter in view of the fact that it is divided and connected to both members of the joint, thus reducing the weight and cost of manufacturing the joint without impairing its efliciency.

If desired, the wheel-carrying member or tread member 4 on the outside member A of the joint that comes into service after the heads of the rails have worn down can be omitted, and both the inside and outside members of the joint formed in the same manner, as shown in Fig. 5. Instead of providing the members A and B with stops or other devices that bear against the webs of the .rails and thus limit the inward movement of said members when the end bolts of the joints are tightened, the two members of the joint that embrace the rails can be so formed that the portions thereof which lap over the base flanges of the rails are spaced slightly away from the base flanges'of the rails at the ends of the joint, thus permitting said members to move inwardly when the end bolts of the joint are tightened without causing the portions thereof that lap over the base flanges of the rails to exert downward pressure on the rails at the end of the joint. In Figs. 6 to 9, inclusive, I'have illustrated a rail-joint constructed in the manner just described, the two side members A and B being provided with portions 2 that bear snugly upon the base flanges of the rails at the center of the joint but are spaced away slightly from the top faces of the base flanges of the rails at the ends of the joint, as shown in Fig. 8. The rail-supporting portions 15 and 15 of the members A and B, respectively, are provided with flat rail-bearing surfaces 6 at the center of the vjoint, and downwardly inclined rail-bearing surfaces 7 which are normally spaced away from the rails soas to securely hold the terminals of the rails s am will be drawn inwardly toward the rails, but as said members are so designed that portions of same come into contact with the edges of the base flanges of the rails before the portions 2 at the ends of the joint come into engagement with, or exert downward pressure on, the base flanges of the rails,

there is no liability of bending the rails vertically when the end bolts of the joint are tightened. If desired, the portions of the members A and B which contact with the edges of the base flanges of the rails when the end bolts are tightened, can be rounded off at the ends of said members, as indicated by the reference character 9 in Fig. 7, so

as to prevent nicking of the rails.

In addition to the desirable features previously mentioned, a rail-joint of the character above-described is admirably adapted of the joint on whi 'rails rest, and independent downwardly infor use with electrically-bonded rails because there is suflicient pace between the webs of the rails and the two side members of the joint to receive heavy cables 16 that form a bond between the rails, said cables being shown in broken lines in Figs.3, 4, 5, 8 and '9. r
