- I The invention relates to railroad track' structures and especially to railroad track g structures wherein the ties are formed from metal.

i The object of the invention is to provide an improved form and construction of anticreeping arrangement for both the rails and the-ties, andfor a consideration of what I believe to be noveland my invention, attention is directed-to the following specifica- 5 tion and the claims appended thereto.

In the drawing, Fig. 1 is a top plan View of a track structure embodying my inven- 'tion, and Fig. 2 is a perspective view thereof. Referring to the drawing, 1 indicates go track ties which are formed of ,metal and which embody as a part of their structure .7 angle bars 3 and 4 located at opposite ends l of the tie. In the present instance each-tie is shown as comprising two lengths of tie 5 bars 5 and 6 which are fastened together at I their ends by the angle bars 3 and 4 and on their top surfaces by plates 7 and 8 which 7 form supports for the track rails. The plates 7 and 8 are shown as being standard 7 o tie plates and they are welded in place as is illustra'ted at '9. The rail positioning and.

holding rib of the tie plates is indicated at '10.. In the tie plates are two spaced openings 11 and- 12 between which the base flange of the track rail lies. The-head of the track 'rail isindicated at 13, the web is indicated at 14 and the base flange is indicated at 15.

r The rail is fastened to the-ties by fastening means comprising two members, a rail clamping member 16 and a fastener 17. The

rail-clamping member comprises a short U- -shaped bar having a central .portion 18* which lies in the tie plate opening,-an -upper inturned end 19 which projects over thebase I flange of the rail and a lower inturned end .20 which extends beneath thetie plate. 'It is held in place by-the fastener 17 which-is in of my present invention, the track tie structare forming the subject matter of my Pat 'ent 1,657',241 January 24, 1928, and the fastenin means forming the subject matter of .86 my. atent- 1,657,242,'a1ready to.

applied.

They are illustrated onlybyway ofexample and are to be taken as typical of any suitable construction to which my invention may be According to my "invention, I make the an- -v le bars 3 and4 at the ends of the ties of a length-such that they abut against each other as is indicated at 21, and I- then provide at vsuitable points on the rail base flanges projections 22 which stand on opposite sides of the end 19 of a rail fastener. Projections- 22 may be built up-by fusing metal to the rail flange, using a-welding machine for the purpose, or they may be formed on the rail when itis rolled. Projections 22 need be provided only at spaced points, it beingunnecessary to provide them-at eve tie. o fact, at one tie withinthe length 0 each rail may be suflicient. With this arrangement,

creeping of the rail is prevented by'projections 22 engaging ends 19 ofthe rail fasten ers. And the abutting angle barsat'the ends of the ties serve to distribute the stress among theseveral ties so that the stress is not borne by the single tie appurtenant to thepiojections 22. Since the anglebars at other, each individual tie is held from displacement by the adjacent ties. v By the above-described arrangement, therefore, ,wherein I provide abutting flanges orprojections 3,4 at the ends OfjhG tIGS which flanges OIf'PIOjGCtlQIlS form apart of 'the ends of the successve ties abut one anthe ties in combination with projections 22 appurtenant to certain of'the ties and which track structure wherein the ties mutually support one another against. displacement and one wherein the rails are held from creeping. Bythus providing the abutting projections on the ties, I obtain the impor- I V I I .prevent creeping. of'the rails, I provide. 2.

tant result that it becomes necessary to;pro-. vide rojections 22 on but few ties per rail 'lengt it being in fact necessary inmost instances to provide projections 22 appurte- "nant to but one tie per rail length. This serves to simplify the'structure and makes it possibleto provide. the anti-creeping arrangement at low cost. v

-The use in the combination of an le bars '3 and 4 at theends of the ties a ter the manner illustrated is of' especial utility since I v the vertical partsior plates of the angle bars serveto anchor the ties'in the ballast against endwise movement while theabutting of the I What I claim as new and desire to secure by Letters Patent of the United States, is

1. In a track structure, the combination of a plurality of ties having abutting projections at their ends whereby'the ties mutualwhich form a part of the tie structure, the

angle irons of'adjacent ties abutting each other, a rail on the ties, and abutting projections on the rail and at least one of the ties to prevent creeping of the rail.- 7

r 3. In a track structure} the combination of a plurality of ties, each tie having transversely-extending platesv at its ends which project beyond the confines of the tie and I0 ly su port each other, a raiLon the ties, and abutting projections on the rail and at least on of the ties to prevent creeping of the ral '2. In a track structure, the combination of ll a plurality of ties, each tie having transversely-extending angle irons at its ends form a part of the tie structure, the plates I of adjacent. ties abutting each other whereby the ties serve to. mutually support one another. I f In witness whereof, I have hereunto set 80 my hand this 15 do. of September,'1927.
