RAIL IEIIILIIZIIEIQ I.
Application filed, August so, 1926. Serial No. 132,546.
. My present invention relates in general to paying projects and has particular reference 'to a so-called rail filler for insulating therails of street cartracks, as. an exainple, from the street paving in which they are imbedded, so as to compensate for'expansion and contraction of the pavement as 'well as to deaden the sound of, rafiic over'the rail and otherwise protect the installation'from wear and tear. a
The salient features of the presentinven- 'tion are" illustrated in. the accompanying drawing, in which- I Figure 1 is a perspective view of a rail with an adjacent paving structure, and illustrating the application of the invention; and
Figure'2 is a detailed perspective view of one of the filler members. 4
Figure 3 is a detailed Perspective view of a modified form of the invention. a
'Referring now tothe drawing in. detail, andfor the purpose of illustration it-may be considered that the rail, which in the present illustration happens to be of the flange type,
has the usual head A, base B and connecting. web C. The space defined by these parts very often is simply filled in with the paving material so that the pavement, and rail be-- come a unitary structure, at'least so far as concerns any *attempts in lnsulatlng the rail so as to deaden the sound of traflic over the tracks, compensating for expanslon and con-' traction of the paving structure and other.
wise improving the installation.
According to my invention I propose to make up a sectional r il filler, so to speak,
I the same comprising a plurality of members 5, preformed so as to fit and fill the space between the head and base of the rail, and with the members adapted to be progressively forced into the space with their confronting ends in abutting relation. In other words, the filler will extend continuously.
along the rail.
The material making up the composition of the filler members should be selected for its inherentompressibility, waterproofing qualities and sound deadening qualities. To
' this end ll would suggest that a composition of asphalt and various kinds of fibrous material be used. The composition of the masame.
terial is more or less immaterial so far as concerns my present invention, and for this reason I need not gQlIltO the details of the lit so happens that it is rather incenven ient to mold or otherwise design the filler members so as to completely insulate the rail. However, to accomplish this oblect I have devised an insulating covering 6 for the members, which preferably comprises a waterproof feltedsheet,'the same being applied to-the' members, and due to the adhesive nature of the asphalt the covering will adhere when so applied. At any rate the By referring to Figure 1 it will-be readily seen that with the construction described I can completely insulate the rail from the paving material, so that not only is a waterproof joint made-but the sound deadening qualities of the joint will be greatly improved, and this improvement also applies to expansion and contraction.
As shown in Figure 2 the aprons may lie across the perpendicular outer surface of the members when the same are packed for ship ment, and turned up as indicated by the dotted lines when the members are' applied to the rail.
The covering also acts as a reinforcement for the members and as 1t passes around the same it will insulate the members from the rail. This is of no special importance except that it does increase the insulating qualities of the filler and holds the shape of the same, so that it is not so likely toooze in 'hot weather nor crack and become brittle in ply a strip 6* applied along opposite horizontal edges of the members, so as to provide the insulating aprons as at 7 and .8. hen occasion demands thespace on both sides of the connecting web 0 may be filled with the same material, although it would naturally be preformed or otherwise shaped to correspond to the'dimensions and contour of the space;
