TRACK GNSTRUOTION.

1b, all whom 'it may concem: f "Be it known thatul, HENRY- EHMAN, a citi zeri of the United States, residing at St. Louis, State .of Missouri,.have invented cer- -tainvnew an useful Improvements in Track Constructions, ofwhichfthe. following is a full, clear, and lexact descriptiq reference being had to the accompanyindrawings, forming a part hereof. l

My, invention yhas', relation to improvements in track constructions particularly adapted f or street calls; and it consists in the novel details more fully s et forth in the' as follows specification and pointed out in the claim.

In the drawings, 'Figure 1 is a to plan of a section of my improved track; ig. 2 is a transverse section on v,the line 2-2 of Fig. l; Fig. 3 is a section at right angBles to Fig. 2 on the. line 3'-3 of Fig. 1 ,and ig. 4 is an 'enlarged cross section, taken through the rail andconcrete base.

The objectof my invention is to provide a Atrack for Streetcar-s which will entirely dispense with the use ofivooden or com osition ties, the supporting bed for the ra' s being entirely of concretef,to which the rails may be secured at very little cost.

The invention more particularl resides in features of construction, the a vanta es of which will be clerl apparent vfrom a etailed descriptiono'f e invention, which is Referring to the drawings, Bv, re rosents I a layer of concrete extendin the ful length and wid-th of the track, an ofathickness corresponding to that prevailing .in the usual wooden ties.

' along the bottom of-tlie concrete layer are series of tranverse reinforcing plates l em- 'and likewise serve as means for securing thereto the clamps .3 and 4 res' outer clamp or she" '3 is in angular@ late following the ectively. The 'forni` of an and outer ange o the rail, being reinforced by. a rib.`

- The Inner clamp or shoe 4 engages the web and inner flange of the rail, bolts 5 likewise `the bo ts 5. In addition thereto, bolts 6 secure the vertical portions .of thesh'oes to the webof the. rail.

At the joint' between two are widened, theouter shoe 3"' having the rib'adisposed centrally and opposite v'the joint, .the shoe 4 being corres ondingly widened to receive the connecting olts 6 as shown. v

The cost er mile is much-ess than with wooden tles, and in those portions of the country where Wood is scarce the track here shown is eminently dewood decays, and any disintegration of the concrete ma .be readily remedied.

c aim' is A track comprising a concrete bed extendand bottom transverse reinforcing plates embedded therein and flush with the oppo- 'uptper series of platesand on the concrete be between thev plates, outer clamping shoes ,engagmg rail, an the top plate beyond the rail, Iand of the outen rail-trea` to the lower end of the shoe, lan inner shoe engaging the web and inner flange ofthe rail, and securing bolts assed through the shoes, plates and concrete the shoes to the rail web, substantially. as set forth. f
