MENT G011111554118174, 02f! cn cAeo," InLnvors, A conroRn'rIoN or in IivoIs RAIL BRACE Applicationfiled January 16,1931; iSerial Nm SQE LOSGQ i This invention relates to an improvement 1n theconstruct1on of a'rail brace such-as-is used forbracing rails against sidethrusts which tend to displace a "rail laterally or to tip the rail. i,

The main objects of the inventionlare,fto provide an improved form of rail'brace which can practicably be made to lit the desired portions of a'rail so as to effectively brace the rail, while at the same timeavoidingexcessive wear on either the brace 01'- the rail as anincident to the normal relative movement therebetween; to provide such an improved rail; brace which can be economically made, for instance, by dropforging; and, in general, it is the object of the inventionto provide; an improved braceof the type referred to." s

Other'objects and certain advantages of the invention will be understood by-reference to the following specification and accompanying drawings (twozsheets) in whichtwo selected embodiments illustrated. In the drawings: i j

Fig. 1 is a side elevation of the improved brace, showing the same applied to a rail;

Fig. 2 is a plan of the improved brace; I Fig.- 3 is a' sectionon the line 3-'8 of Fig. 1, and v Fig. 4 is a view similar to inga modified construction. v v 7 Referring nowto the drawings, a rail of conventional type is illustrated at 5,'the same being seated on a tie 6. The rail may be secured to the tie 6 by spikes in the usual manof the invention are omitted in the drawings, inasmuch as the invention. herein involved isnot concerned therewith. i j Such railsas guard and stock rails", switch points, curved rails, and others, are subjected to considerable lateral thrusts which have a tendency to displace such rails laterally or to tip the same. For bracing suoh rails against such thrusts, various forms of braces are .provided. 1 I11 the drawings,fthe rail, represents any rail which requires bracing} against lateral thrusts, and one form of'my 1, but show 2 and 3.

Such structures result 3 in a considerable or wearing effect of the normal relative movement between-the brace and rail is largely raid andthe brace is materially prolonged.

In 'etlrer words, by' e li'min ating' the Wedg in-g efiect ef the-brace betw-een the rail; head and base fliinge,--Wear on the parts material-1y I As'indicated'at 24-,the front part- 0f the brace'intennediate its upper and lower fillet fittingp'arts is recessed. S'uch'recess effects a--saving metal and consequent reduction costofthe bra'ce,-while also avoiding the necessity of forming the entire front area of thebrace p'arft llto accurately fit the entire area o fthe-web $5. "By relying on the reduced areas o f contact or engagementfbetween the brace {and rail i asshown,- it iscbvious ly much easier {to produce-an accurate fit'betweenthe reduced portions; It is found that such reduc'ed contaot areas -may be: formed with c-ient accuracy to constitute contact areas,

web of the ra il as'indicatedat 29,an'd the base portion is' spaced upwardly from thetopsurface 23 of-t'herail base flange so that the only areas 'offcontact occur at t'he fillets 1 3and1 8; This arrangement, while being a greater departure from themore or less has substantially the same advantages thereover as those explained above'in connection p with the structure depicted 1n Figs. 1, 2 and even easier to secure an accurate fit between the still further reduced areas f =-contact whichiare nevertheless sufiicient for all prack tical purposes. In this modified construe: tlonj, such limited wear as occurs between the base 16 of the brace and flange 14 of the X rail in the first describedconstruction is practically eliminated. v
