There are a pair of tie plate adapted for application to a, ti d rail clips 9 and a description of one of them will having flanged outer edges and shouldered side ce be au th y are d pl h r il lip edges adapted to abut on the opposite edges of 9 is curved in consonance with the rail base and the rail base, a pair of clip anchors adapted reweb and it abuts on the flange 2 and it is p spectively to abut at one end on the tie plate vided with a T slot 10 adapted to receive the T outer flanges and each having at the other end an head 5 and to be held down thereby. The tie upstanding T head adapted to bear on the adcl ps extend over the rail base and up the web jacent edge of the rail flange and each having a of the rail to the neutral axis. ll indicates aknee loop extension adapted to pass under and friction and compression agent such as Masonbear on the rail base and to lie alongside the tie ite (compressed wood) or rubber, and it is inand extend to the opposite edge of the rail base, a terposed between the rail, shoulder, and tie plate, pair of rail clips curved in consonance with the and between the rail clip and rail web and base. rail base and web and each adapted to abut on 12 indicates screw spikes for attaching the described fastening, which is locked to the rail, in place on the tie.

From the foregoing description it is evident that the entire rail base above the tie plate and the web of the rail up to the neutral axis of the same is used as a bearing agent in fastening the rail to the tie. This increases the bearing area and stress distribution area from the usual four square inches to fifty-six square'inches or thereabouts and the above area. is coupled to the opposite side of the rail base through a common anchorage, using the rail itself for hold down anchorage. In assembling the parts the tie .plate I is first placed on the tie b. and the rail a is then placed on the tie plate with the edges of its base in contact with the flanges 3. The clip anchors 4 are then applied with their T heads 5 in contact with the edge of the rail base and to one side of the flange 3 and the outer edges of the clip anchor are in contact with the tie plate flanges 2. The knee loop extensions pass along the tie and under the rail and the knees I abut on the bottom of the rail base, the hook 8 engages the head of the rail base opposite the edge where the slip anchor is arranged. The hook 8 may be hammered or otherwise forced into contact with the rail base. The rail clips 9 are then applied with the T heads 5 through the T slots l and they are driven inward until their outer edges lie in engagement with the flanges 2 of the tie plate. The rail and rail fastening are thus completely interlocked so that they act as a unit rather than as independent parts. The function of the screw or other spikes I2 is merely to connect the rail fastening and the tie and during the assemblage of the parts of the fastening the openings l3 for the screw or other spike [2 are brought into alignment. The holding power and frictional resistance of the fastening opposes creeping of the rail in either direction. Furthermore the bracing action of the described fastening checks sidewise stresses. The Masonite or other material which is compressed between the shoulders of the tie plate and between the base of the rail and top of the tie plate prevents cutting or wearing of the tie plate by direct contact of metal or metals and furthermore that material has a sound deadening effect and eliminates noise to a great extent. It may be remarked that there are no bolts or the like for securing the rail fastening to the rail and in the usual type of rail fastenings the stresses from the rail to the fastener is distributed entirely through a bolt or the like which is constantly being worked or stressed. The described parts of the fastening can be manufactured at little expense and are easily and quickly assembled.

Since the extensions 6 lie on opposite faces of a tie b, they serve to square the tie and the rail and rail fastening. When the extensions 6, are in the form of loops they are springy which is an advantage in some cases. The purpose of bevelling or undercutting the ends of the clip anchors 4 and rail clips 9 is to facilitate their assembly in the flanges 2 by driving them after they have been properly mounted in respect to the rail. The outer walls of the head of the T-slot III, are also bevelled or undercut to facilitate the entrance of the T-head 5 when the rail clips are driven to place.

The embodiment of the invention described is particularly adapted to high speed railroad interurban open track speedway and elevated track construction but for other uses itis not always necessary or desirable to use the complete conlips 9' for engagement with the upper surface of the rail base.

It will be obvious to those skilled in the art to which the invention relatesthat modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited to such matters, or otherwise than the prior art and the appended claims may require.

I claim:

4. The combination substantially as described in claim 3 in which said securing means comprises spikes which penetrate the rail clips, clip anchors, and tie plate and enter the ties to hold down the fastening elements and rail to the tie.

5. Means for fastening railway rails to ties consisting of a tie-plate adapted for insertion between the upper surface of the tie and the bottom surface of the rail and shouldered intermediate its side edges to engage both edges of the rail base and having upstanding flanges at said side edges, a pair of clip anchors having T-heads overlying the tie plate and other means underlying the rail base at each edge thereof, a pair of rail clips engaging said upstanding flanges and also the upper face of the rail base and parts of the web and having T-slots engaging the T- heads, whereby said anchors and clips are adapted to be clamped together and to the top and bottom parts of the rail base and to the rail web, and. means for securing the clip anchor and rail clip to the tie plate and tie.

6. Means for fastening railway rails to ties consisting of a pair of clip anchors adapted to be disposed at the respective sides of a rail and each having an extension arranged along the side of the tie and adapted to under span the rail and to engage the under face of the rail base at both sides thereof and to engage the far edge of the rail base, a pair of rail clips adapted to be superposed on the clip anchors and shaped to engage the top face of the rail base and a portion of the web, means interposed between the rail clips and clip anchors for clamping them together in pairs, a tie plate upwardly flanged to engage the rail base and the ends of the clips and adapted to be superposed between the top surface of the tie and the rails, anchors and clips, and means securing said anchors and clips to the tie.

'7. In means for fastening rail way rails to ties, a tie plate, clip anchors and rail clips arranged on top of said plate on the same single tie, T-heads on said anchors and T-slots in said clips located wholly above the tie plate and interconnecting.
