as distinguished-from those made entirely of wood or metal.

The primary object of the invention is to provide a composition tie of simple and inexpensive construction which has the necessary anddesired degree of flexibility and elasticity and can be readily substituted for the ordinary wood tie.

' One of the serious ditli culties encountered in, establishing and maintaining proper roadheds is to prevent the unequal distribution of pressure on the ties. As the greater portion of wood tie is located between the rails, the pressure per square inch on the tie is consequently less between the rails than outside the rails and the result is that when pressure is applied to the rails the outer ends of the ties are depressed while the center of the tie is held up. Thus the tie becomes center-bound and the etlect ofthis is to cause a railroad train moving over therails to be pulled uphill to the. extent of the weight and power necessary to bend the-ties to their established base. To prevent this bending action requires constant-attention on the part of the section men on the road as it is necessary for them towatch the ties carefully and keep them filled and tamped under the outer ends.

My invention overcomes this difficulty by providing-a tie comprising a pedestal for "each rail arranged to receive and support the rail at'its center. This arrangement. provides for a uniform distribution of the load on the base of the pedestal and con sequently whatever settling, of the pedestal takes place in service is necessarily uniform throughout the area of the pedestal, thereby improving the foundation for the pedestal and wholly avoiding the necessity for filling and tamping now incident to the use of wood and metal ties.

Another important object of the invention is to provide a railway tie comprising pedes= tals spaced apart for supporting the rails and made of a plastic material, such as con.-

-' cretei'eintorced and connected by a trussed metal structure in such a manner thatthe pedestals will resist not only the compression strains but also the tension strains to which they are subjected in'service;

Further objects of the invention are to provide 'a composition tie which will have suflicient elasticity and flexibilityto properly adjust itself under the load carried by the rails and at the same'time distribute the load evenly and uniformlythroughout the pedestals supporting the rails; toreinforce the. pedestals in a simple and etlicient manner to preventt-hem from breaking when under load; and is to reduce the cost of maintenance of a roadbed by providing an efficient substitute for wood which will have a much longer life in service than a wood lie and which will avoid the unequal dis-" tribution of the load which produces center-. bound ties and overcomes other objections to wood ties.

In the accompanying drawings illustrating a preferred embodiment of the invention, Figure l is a plan view of tie showing the rails inplace thereon; Fig. 2: is a side elevation o f'the tie showing the rails in section; Fig. 3 is an enlarged longitudinal sectional View through one of the pedestals of the tie and the rail; Fig. 4 is a transverse sectional vieiv on theline 4-4 of Fig. 3; Fig. 5 the rail-on the-tie 1n a position to increase the track gage, on, a curve for example,

Fig. 6 shows one end of the 'trussed metal structure with the longitudinal truss rods and the transverse rods in position thereon, the latter being in section; Fig. 7 is a trans: verse view on a line indicated by 7-7 Fig. 6, and showing the metal portion of the tie;

Fig. 8'is a perspective view of one of the' wear plates; Fig. 9 1s a perspective. view of.

an anchorplate, and Figs. 10,11 and 12 are perspective views of transverse rods'and a wedge block respectively.

Referring to the drawings in which letters of reference indicate corresponding parts of the several figures, .A, A, designate the two pedestals ot' the tie which are spaced apart to occupy a position centrally disposed below the track railsB. These pedestals are constructed alike and each is preferably made of a plastic composition such.

as concrete reinforced and connected, as hereinafter more specifically set fortlnby the trussed-metal reinforcing structures-C, C, which are preferably embedded in the is adetail sectional view showing pedestals and extend approximately throughout their length. I

For the purposeof greater strength I may employ, in addition to the trussed, metal reinforce, transverse rods D and longitudinal truss rods E in each pedestal. verse rods have bent ends-(Z to engage 'the transverse rods D- on the top of the 'trussed reinforces and engage one of the transverse 1 rods D at the bottom of the'trussed reingaged by the longitudinal truss rods arepreferably bentas indicated by the trans-' and longitudinal truss rods form-,a skeletonrailway tie is s ubje'ctedare tension'strains at forces.

The trussed'structures arejpreferably located adjacent the sides of the ped estals and are engaged at or'aboutthe top and the bottom thereof by the transverserods, and the truss rods are-located between the trussed structures and extend approximately throughout the length, of the pedestal in reverse-1y inclined directions from the center of the pedestal. This construction provides.

a hubstantial and compact concrete'pedestal, strongly reinforced so as to prevent the ped estal, from splitting longitudinally and-also to prevent the concrete from crumbling or breaking away from the reinforces without first changing or} destroying these reinforces; that is to s'ay,without'changmg the length of-one-of the members of one or more of the triangles of which each reinforce is composed. The principal strains to WhlCh a the bottom of the tieandcompression strains forth in my The transchanged as desired.

at the top ofthe tie due to the tendency of the tie to bend under the pressure of the load on the rails, and the trussed-metal reinforces embedded side byside in the pedestals and connecting the pedestals serve'not only I to effectively "resist "these tension strains but they also confine and hold the concrete so that it will resistany' tendency to split or break down or-c rumble, and will be mamtalned n a solid compact condition;

advantage of the use of Wood tiesis, the constant tendency to depress the ends under; the

pressure of the load carried by the rail until they become center-bound, that'is, raised at the center'and depressed at'the ends, and

. section men are'constantly employed in tamping the ends ofthe tiesjt'olift them up .to the roper grade. Thiscenter-bound ae- 7 tion 0 the tie is due tothe fact. that the and consequently the pressure per square inch on the tie is less between the rails than outside of the rails. .My invent-ion over- 1 comes this trouble 'by providing two pedesscribedtforms a solid and substantial oun- 'tals of approximately. thesame size and spaced apart to support the rails oe'ntrally disposed thereon, so that there isas much of the pedestal on one side of the rail-as on the o other, and consequently .there is no oppors" t-unityforthe tie to become center-bound. The concrete pedestal. reinforced with the l trussed .met-al structure, as shown and'dedation for the rail, combining the pressure 7 resisting iquaIit-iesof the, concrete with the .tensionresisting; qualities of the trussed re- ,inforce, and the'load carried: by each .rail

centrally positioned on the pedestal will' be distributed evenly and uniformly overthe entire base of. the pedestal. The pedestals are permanently connected together the truss reinforces "which provide the necessary amount of elasticity and flexibility between the pedestals to permit them to adjust themselves relatively and independently as the conditions of-serviee may require. f "Besides the other advantages of my invention hereinabefore noted itwill be readily l-unders to'od that cross ties-of standard size may be, employed forrails of different sizes v by simply employing wood keys of the right size to Sec'urethe rails in-place.
