CLARENCE S. DAVIS, 0F BUFFALO, NEW YORK, ASSIGNOR TO THE DAVIS METAL TIE dc RAIL CLAIVEP CORPQRATION, 0F BUFFALO, NEW YORK, A GORIORATIQN OF NEW YORK METALLIC RAILHAY TIE AND ASSOCIATED PARTS Application filed March 27, 1929.

invention relates to metallic railway ties and associated parts, and has for 1ts ob jeet the provision of a metal tie having a rail seat, of a dimension transversely, sulficient to provide the proper seating for a rail resting thereon and a supporting base of v greater transverse dimension than said rail seat so as to provide proper support for the tie upon the road bed; the combination of a rail eat of definite transverse dimension and a wider supporting member enabling the rail to be made comparatively light in weight without detracting from its supporting qualities and rigidity. V

Another object of my invention is to provide a metallic tie having a rail-seating member and a supporting member connected by a web and having the supporting member provided with anchors along its length, preferably disposed in planes at opposite sides of said web. I

Another object of my invention is the provision of new and novel means for securing the rails of a railway track to the ties; and to otherwise improve on metallic ties and railsecuring accessoriesthereto. a The invention consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.

Reference being had to the drawings detail; 15 designates the metallic ties which are of substantially I-formation, each tie compri'sing an upper, rail-seatihamember 16. a

CO1; 'aratively wide supporting member 1 pa'rallelwith said rail-seatingmember. and central vertically-disposed web .18 connect ing the members 16 and 17.

The rail-seating member 16 comprises" two flanges extending laterally in opposite directions from the upper edge of the vertical web 18..wh1le the supporting member 1? consists of two somewhat wider flanges extendinc: laterally in opposite directions from the lower edge of said web.

. Through each of the flanges forming the supporting member 17. which may also be termeda rest, openings 19 are punched and the metal from these openings bentbut may be in the form of depending members on the rest secured thereto by welding, riveting, or otherwise.

The ties are placed on or in the roadbed, and the anchors 20, 21 forced into the roadbed, serving to prevent lengthwise move ment of the ties, or movement transversely with respect to the direction of the track supported on the ties.

The rails of the track are designated by the numeral 22. and in Figs. 1 and the abutting ends of two rail lengths or sections are shown. These rail lengths or sections are connected together by my improved splice members 23. said splice members overlying adjacent ends of two sections. The rails. be tween the ends thereof. are connected to the ties by means of clamp members 24. The sections of the rails abut over the center of a tie and the splice members 23 are seated upon three ties bridging the spaces between said ties. Each splice member has an outer flat portion 25 which lies upon three of the ties. as stated. and an inner portion 26 conforming in shape to the web and flanae at each side of the rail 22. The inner portions 26 of said splice members bear against opposite sides of the web of a. rail and against the two flanges thereof. the edges of said flansl'es being in contact with shoulders 27 formed on the undersides of said splice members. These splice members are secured to the rail in the usual manner by means of bolts 28 and nuts 29 applied to said bolts. and they are pro vided at their edges with angular retainer lugs 30. which are passed through openings 31 in the two flanges forming the seat-inn? member 16 of each tie. The retainer lugs 31 are arranged in pairs spaced at regular intervals along the splicing members. and therefore determine the spacing of the ties on which said splicing members are seated.

In placing the splicing members in position on the ties, it is necessary to enter the angular retainer lugs 30 through the openin as 31. after which the splice members may be swung inwardly and downwardly aeainst the web and flannes of the rail. This will bring the bolt holes in said splice members into registration with the usual elongated bolt holes in the rail and permit the securing bolts 28 to be fastened thereto.

As is common in railway construction work of this kind, the nuts 29 bear against lock washers 32. which in turn are forced by the nuts 29 against the upstanding or wehbearing portions 33 forming part of the inner portions 26 of the splice members.

The ends of the angular retainer lugs 30 bear against the undersides of the, flanges forming the seating members of the ties, and they serve to fasten the splice members to the ties and prevent movement of the ends of the rail sections laterally. They also prevent movement of said ends in a vertical direction so long as the nuts 29 on the bolts are properly tightened. However, under continual use and heavy traiiic over the rails, the vibration of the track structure, including the rails, the ties, and the connecting mediums, will eventually cause the nuts to become loosened, and the retainer lugs at the outer edges of the splice members, when used alone to secure the splice members to the ties under such conditions, would be insuliicient to prevent slight vertical movement of the rails on the ties, which would result in a slight tilting of the splice members with the angular retainer lugs as fulcrums for the same. To guaro against this, I employ retainer yokes or yoke-like fastener members 34L, which are constructed of bar material. Each yoke or fastener member comprises a horizontal portion 35 and two depei'iding portions or legs 36 at opposite ends of the horizontal portion. Formed in each. of these legs is a key hole 37, the key hole in one of said legs being disposed in a lower plane than the key hole in the other, and these key holes are preferably of oval formation with their greater dimension disposed in a vertical plane.

In the preferred form of my invention, the legs 36 of the fastening members 3 1: are passed downwardly through openings 38 formed in the flat portions 25 of the splice members, and through registering openings 39 in the opposite flanges of the seatingmember 16 of the tie. Thus positioned, the horizontal portions 35 of said fastener members be r against the flat portions 25 of said splice members, and these horizontal portions are drawn down firmly and securely against said fiat portions by means of tapering or wedge lock keys #10 passed through the key holes 37 in said fastener members and through an opening 41 in the web of the tie 15 alined with said openings 37.

Each of said tapering or wedge lock keys 40 is round in cross section, and slit at its smaller end, as at 12. The lock keys are passed through the key holes 37 and the openings 41 in the web of the tie, and are driven firmly in place so as to draw the fastener members .34; securely against the upper surfaces of the flat portions 25 of the splice members. v

Where the flanges forming the seating member of a tie are gradually thickened from their outer edge toward the web 18, these flanges are roused out in any suitable man.- ner, as at 43, Jig. 6, so to provide long bearings for the lock keys, the gouged-out portions forming; continuations of the openings 41 in the webs of the ties. here however, tie is constructed of the cross section shown in Figs. 11 and 12, the gouging-out of the seating member of the tie is unnecessary, due to the fact that the flanges forming said seating member are of even thickness from edge to edge of said member, and in such cases the opening 41 has its highest point alined with the under surface of the seating member; thus giving the lock key bearing along its-full length. against the under surface of said seating member. When the lock keys are driven tightly into place, the end portions thereof at opposite sides of the slit 42 are bent ,t a rightangle to the length of the key. as as, these bent portions being driven against the outer side of the leg 36 through which the smaller end of the loclr lrey'prd iects; thus firmly securing the fastener member 34- in the splice member and to the tie, without possibility of movement under any vibration to which the track structure may be subjected.

The clamp members 24. are used along the rail lengths or sections, between the splice members, four being employed for each tie, one at each side of each rail. These clamp members differ from the splice members in that they are shorter, and may or may not have the web bearing members adapted to lie against the sides of the web of a'rail. In Fig. 2, the inner marginal portions of these clamp members-termina e betweenxthe edges of the rail flanges and the rail web. and on a straight-lined portion of the track I deem it desirable to use rail clamps of this kind. Clamp members provided with web-bearing portions 33 are employed at the outer side of each rail when curved, but if desired, these clamping members be employed on both the outer and inner sides of curved rails, or generally along therails whether straight or curved. a

With my improved fastener means I do not consider it necessary to extend the clamp members inwardly beyond a plane passing through each flange of the rail, as it s only necessary that the clamp members overlie the outer marginal portions of the flange. In preferred construction, tnese'clamp members are also provided-withshouldersEZ'Z to engage the outer edges of the flanges and with the retainer lugs- 30 which through the openings 31 in theties in thesame manner as the retainer lugs of the splice members.

Like the splice members, the clamp members are provided with openings 88 through which and the registering openings 39 in the seating members of the ties, the legs or depending portions 36 of the fastener members 34; are passed, and through the openings in these legs the lock keys d0 are passed a. *l fastened in the same as those employed for securing the splice members the ties. V

in the modification shown in 10, the fastener members 3% are solely'relied upon to secure the clamp members to the ties, the angular retainer. lugs employed in the preferred construction, already described, being dispensed with. Vhen so used, the openings 30 in the ties are dispensed with, and this keys 4:0 are somewhat longer and passed through the key holes 37 in said depending legs, andbear against the underside of the seating member along, its ;full width, especially where said seating member is of even thickness from edge to edge, as shown in Fig- 12. The ends of the lock keys are bent over in the same manner as in the preferr d construction.

By the use of this invention, all boltsare dispensed with, excepting such as are passed through the upstanding or web bearing portions of the splice members and the webs of two abutting rail sections; Fastener means of novel construction are also employed for splicing rail lengths or sections together and for securing the rails to the ties between the spliced ends of the rail sections,which will not only assurea secure fastening of the rails to the ties, capableof withstanding any jars to which the track structure be subjected, regardless of the weight or speed of moving loads passing over the same; but

which will provide splices at the ends of;

rail. sections suiiiciently rigid and secure to permit the bolts passing through the rails to be dispensed with. Such bolts are employed only for increasing the marginlof safety and to strengthen the ends of the, rail sections when provided with bolt holes, as they usually are. The fastening means provided in conjunction with the tie construction shown and described, guards against spreading of the rails and prevents loosening of the fastening elements under the severest jarring to which the track structure may be subjected.
