BAIL-JOINT.

To all whom it may concern Be it known that I, RICHARD P. WILLIAMS,

a citizen of the United States, residing at No, 1285 Lincoln Place, Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Rail-Joints; and I do hereby declare thefollowing to'be a full, clear, and exact description of the invention, such as will en-' the rail joint which tend to break the .rail

along the line of the bolt holes, and also tend to elongateand loosen the bolts.

The purpose of my invention is to compensate for and thereby eliminate or greatly diminish the eifect of these strains; and, as

Krill hereinafter more fully appear, I eifect this purpose by a construction wherein the strain transmitted from the under side of the head of the rail to the upper sides of the.

heads of the splice bars is in large parttaken up by the web of the rail, through the intermediaey of longitudinal ribs with which the under sides of the heads of the splice bars make contact. Furthermore, I provide like longitudinal ribs, interposed between the upper surfaces of the inner part of the base of the splice bars and the base of the rail, .so as to transmit to the web of the rail the reaction strains which would otherwise be conveyed from the base to the top of the rail.- By these expedients, I practically neutralize the tendency of the rail to split or crack along the line of the bolt holes, and convert Specification of Letters Patent.

the splice Patented June 24, 1913.

Application filed November 25, 1911. Serial No. 662,288.

Similar letters of reference indicate similar parts throughout the several views.

Referring to the drawing, (1 indicates the head and b the base, of standard dimensions, of a Trail embodying my improvements. and whose end is to be connected with the similar end of an alined T-rail of the same construction; The webs 0 of the alined rails are provided With the usual bolt holes for the passage of the customary screw bolts having the head d, shank e, screw-threaded end 1, and nutg. These bolts, as in the standard construction, pass through the web of the rail andthrough the webs h of the splice bars, which splice bars are provided with the base i and thehead j, in contact respectively with the base of the-rail and the under side of the head of the rail.

Immediatelybelow the head a of the rail, the rail web, is provided with longitudinal 'rib projections in with whose upper surfaces the corresponding lower surfaces of the heads of the splice bars make substantial contact. So also, immediately above the base 6 of the rail, the rail web is provided with longitudinal rib projections lbetween whose lower surfaces and the corresponding upper surface of, the inner end of the base of the splice bar substantial contact is likewise made. 'Sutficient clearance is provided. as indicated at m and n, so that upon drawing up the bolts by means of the nuts g, a strong wedging contact will be made between the projections la and the surfaces of the splice bars ygith whichthey cotipe'rate, and also between the 'rojections l and the surfaces. of ars with which they cooperate. As a consequence, the weight of the rolling stock and thejorce of impact of. the car wheels at "the joints, aretransmitted. from the head a of'the rail in large measure to the projections k and thence to'the web 0; and, likewise,vthe reaction strains from the base i of each splice-bar are in large part transmitted to the projections l and thence to the web of the rail. As a consequence, the effect of these strains, which are normally exerted in the standard rail joint in a direction tending to pyl apart the web of the rail along the line f the bolt holes, is exerted in large part in the op osite direction, thereby counterbalancing t e tendency to tear the rail apart along this line of weakened resistance. Furthermore, a lesser strain is exerted laterally upon the splice bars, in my improved I I claim is:

construction, 59 that the longitudinal tensile strain upon the bolts is lessened and their tendency to elongate diminished, which further adds to the ,etiiciency and durability of the joint. v

In the form of my invention shown in Figs. 1,2 and 3, the web h of the splice bars bears such a relationship to the rail, that, in use, it partakes of the spring effect consid'e cred desirable in the standard rail joint. A greater degree of rigidity, however, can be imparted to the joint, if desired, for special uses, by providing the splice bars, as' indicated in Fig. 4, with inwardlyextending projections n entering the spaces between the corresponding web projections k l, and extending from end to end of the splice bar.

It will be evident to those skilled in the art that rails of the construction shown in the drawing can be rolled in an ordinary rail-rolling mill without; other modification than to appropriately Chan e the last few passes of the present mus:

amount of metal in these projections, the rate of cooling of the web as a Whole will not differ so, radically from the rate of cooling of the head and base as it does in the standard T-rail; consequently there will be a correspondingly less tendency for therail to warp'in cooling or to develop a difierent crystalline structure in the web than is. present in the head-and base. .So also, the longitudinal projections will serve as strengthening elements to the we b -as against any lateral strainseit-her in useor in shipment, and will increase the strength of the rail as a girder, 2'. 6. it- I will increase strength without adding to its height. I Having thus describedjmy invention what 1.
