rhis invention relates to new and useful improvements in railway track construction and more particularly to means for securing the track rails to the ltrack bed.

One obj ect of the invent-ion is to provide a railway track construction which is readily adaptable to both standard steam and electric railways, 'and also street railways wherein the upper surface of the rails is substantially level with the surface of the street.A

Another object of the invention is to pro-py vide a railway construction having novel neans for securing the track rails to the track Another object of the invention is to provide a railway trackV construction having novel means for releasably securing the track rails to the track bed, said means being positioned to permit lateral gauge adjustment `of the rails subsequent to the laying thereof.

Another object of the invention is to provide a railway track construction having novel means for insulatingthe track rails from the track bed.

A further obj ect of the invention is to provide a railway track construction having means for locking the track securing elements thereby preventing the track rails from becoming loosened.

A further obfect of the invention is to provide a railway track construction having means for securingthe rails to the rail bed in such manner asto prevent longitudinal movement of the rail` with respect to the rail supports and commonly known as creeping.

The invention further resides in certain structural details set forth hereinafter and shownA in the accompanying. drawings, in which:

Referring to the drawings, the anchor members lareembedded in a concrete foundation 2, preferably prior to the positioning of the track rails, the said anchor members 1 in thev present instance having their end portions formed to converge toward the track rail as shown in Fig. `1 of the drawings In the present instance the plane -of the inner face of the upper converging `portion offthe anchors 1 is formed at an angle `with respect to both the, longitudinal axis of the .track rail 3 and the horizontal surface of the track bed. The said inner face of the converging portion of each of a pair of oppositelydisposed anchor members l is disposed at an opposite equal angle to that of the other face of the opposite vanchor element, thus permitting the retaining members tobe driven from opposite sides vof each of a pair of oppositely disposed anchors. p y Subsequent to the embedding of the anchor.` members l. a continuous member 4 of wood or other suitable material is disposed intermediate the anchor members l and parallel with respectto the longitudinal aXis'of the trackrail '3, the upper surface ofthe concrete l track bed beneath member 4 havingprevi` Vously been formed by suitable meansy'tof a reasonably true surface for the placementV of said'member 4. The track rails 3 are then positioned on the member 4 intermediate the ioo oppositely disposed or staggered anchor elements 1.

For the purpose of securing the track rails to the track bed, I provide engaging elements 6 having a cutout portion 7 formed therein as shown in Fig. 6 and adapted to engage the outer edges of the track rail 3 when disposed adjacent each of the anchor members l. A second cutout portion 8 is formed in the outer face of the engaging member 6, the purpose of whichwill bef-set forth hereinafter.

For the purpose of rigidly securing the engaging members 6 to the basel ofthek track rail, thereby holding it securely in position, I provide suitable wedge members9 shown in Figs. 3 anda of the drawings, the ysaid wedge members 9 being disposed intermediate the inner face of the upper portion of the anchor members l and the upper face of the engagingmembers 6. In the present instance the edges of the lower face ofthe wedge members 9, normally abutting `the upper face of the engaging members 6 are beveled as shown at 10 in Figs. 3 and 4 of the drawings, to perf mit that portion of the wedge to normally reside in the cutout portion 8 formed in the upper face of the engaging members 6, when the said wedgemembers 9 are entirely inposition, and thus afford a substantial means of preventing the wedge members 9 from becoming separated from theengaging members 6.

As a means for further securing the wedge members in position when the said members have been finally secured I provide a strip of steel 1l which is normally disposed intermediate theupper face of the wedge 9 and the inner face of the anchor member l; and to lock the wedge securely in position it is merely necessary to form one end of the strip 1l over the side of the anchor member l, the other end of the saidv strip l1 being bent over the end of the' wedge 9, as shown in F ig. Y

In the present construction,.I prefer to embed the anchor membersl in the concretev foundation prior to the..,positioning of the track rail 3 and 'it is obvious that the anchor members 1 may be of any suitable 'form providing that the upper inner face thereof is disposed at an angle with respect to the longitudinal axis of the track rails and alsoV at an anglewithrespectto.the surface of the track bed. The use of the wedges disposed as they `are in the present case, permit of the lateral adjustment of the rail to the desired gauge, by first driving one or the other of the opposing wedges. l

In the vcase ,of open track en railways where it becomes' necessary `tol provide 4for electric circuits Ywhich requirerthe insulation of the rail from thesupporting structurer and the y anchor` members, the wedge members 9 are composedV of insulating material, such as Vwood, hard rubber or other suitable insulating material. In such cases the supporting member 4 is likewise wood or other suitable insulating material and it is even desirable to place a layer of insulating mastic, designated as l2 in Fig. l, on the upper surface of the concrete and extending from 'the edge of the supporting member l to the outer line of the anchor members l disposed adjacent each side of the rail; the combination of the insulating mastic, the supporting member 4; and the wedge portions 9 effectively insulating the rail from the anchor mem- `bers 1 andthe concrete base.

In the case of track construction shown in Fig. 7 and particularly adapted` for use in street railways, wherein the surface of the street pavement is normally iiush with the level of the track rails,.and whereinthe in sulation of the track rails' from ythe .anchor members and the concrete base is not required,

it is preferable toV form the wedge 4member and the engaging member of metal andas an integral unit designated as-9l and shown in Figs. S and 9 of the drawings. In this type of construction the track rails are secured to the road foundation in a manner similar to that set forth above' and in addi-y tion a further application of concrete l (see Fig. 7) is disposed about the upper portion of the anchor members and about the wedges to a suitable height thereabove, the customary road surfacing material l5 being subsequently placed thereon to a height substantially level with the upper surface of the track rail. n

It will be apparent that vthe `unit wedge and engaging member 9a may be used in thev having the upper inner face thereof disposedl at an angle to the longitudinal axis of the track rail and at an angle to the plane of the surface of the road bed, and wedge members disposed intermediate and abutting the inner faceV of the anchorl lmembers andthe base .of the track rail for holding the saidv rail firmly in position.
