RAIL JOINT.

Application filed December To all whom it may concern.

Be it known that I, .FREDERIOK E. HARDER, a citizen of the United States of America, residing at.Detroit, in the county 6 of \Vayne and State of Michigan, have invented certain new and useful Improvements in Rail Joints, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to rail joints and it has for its principal object the provision of a joint in which the parts may be more readily assembled than in other similar devices, but which will be secure against accidental separation after assembly.

In the drawings,

Figure 1 is a side elevation of a rail joint showing a preferred embodiment of my invention;

Fig. 2 is a View in horizontal section on the line IL-II of Fig. l, and a Fig. 3 is a transverse section on the line III-III of Fig. 2, looking in the direction indicated by the arrows.

Adjacent to the meeting ends of the rails 1 are formed the usual openings for the reception of the securing bolts or rivets 2, and where the rails are to be used for electric railways, additional holes will be formed to receive the ends of bonding wires 3.

A joint chair 4 is provided which consists of a metal casting having a base 5 adapted to extend under the lower flanges 6 of the rails 1 and having side arms 7 adapted to lie parallel with the webs 8 of the rails, being spaced at a sufficient distance therefrom to permit the introduction of fish plates 9 and a. wedge member 10. In assembling the joint, chair 4 is slid lengthwise upon the lower flange at the end of one rail and the other rail is placed in position with the two ends of the rails abutting each other. The bonding wire 3 will be placed in position if it is used, and the fish plates 9- will then be placed in position, suitable recesses being provided on the inner faces of the fish plates for the reception of the wire 3. After the fish plates are in position, the rail chair is adjusted to bring the openings 11 in the side arms 7 opposite the openings in the rails which receive the bolts or rivets 2. The bolts or rivets may then be introduced. through the openings 11 to pass through theregistering holes in the fish 7, .1922. Serial No. 605,338.

plates and rail webs and the wedge, 10 may then be driven lengthwise between the heads of the rivets 2 and the adjacent side arm" 7, this not only serving to hold'the rivets 2 securely in position, but also acting to clamp the fish plates and the rail webs firmlybetween the side arms 7 of the rail chair. After the wedge 10 has been driven as far as it will go, its narrow end which will project beyond the end of the rail c air will be bent over as indicated at 12 to prevent accidenta-l withdrawal of the wedge.

With the wedge thus set securely in place a and held by the bent over end, all of the members are held securely in position, thus rendering relative movement of the ends of the railsimpossible.

The side arm 7 on the side of the rails opposite the wedge 10 will also preferably be provided with openings 13 to receive the ends of the rivets 2 as a means for preventing movement of the rail chair longitudi-, nally of the ends of the rails.

' The rail chair, will be provided with flanges M against which may be set the supporting ties 15. Preferably there may be a tie under the end of each rail, as shown in full lines, though a tie may be setin the position indicated in dotted lines in Fig. 1 beneath the central portion of the rail chair.

This invention is an improvement upon the structure shown in Patent No. 1,033,767, patented July 23, 1912. In the device therein described, it was necessarythat the parts should be assembled with the rivets in'position within the fish plates before the rail chair was slid lengthwise into position and the rivets would be likely to fall outward into the space between the fish plates and the side arms, making it diflicult if not im- 95 possible to insert the wedge plate.

The present invention obviates the difficulties encountered by the original device, thus providing a highly efficient and readily assembled rail joint.

It will be evident that -many changes and modifications may. be made without departing from the principles of my invention, and I therefore wish to claim the invention broadly within the legitimate and 105 valid scope of the appended claims.

I claim j l. The combination with meeting rails of fish plates fitted against the opposite sides of the webs ofthe rails, a rail chair inclosing the bases of the rails and having side arms upstanding opposite the fish plates, the Webs of the rails and the fish plates be ing provided with registering openings, and one of the side arms being provided With openings registering with the openings in the rails and fish plates and adapted for the passage therethrough of headed pins into the openings in the Webs and fish plates, and a Wedge inserted between said arm and the adjacent fish plate, said wedge extending opposite the heads of the pins to prevent their removal from said fish plates.

2. A structure as in claim 1 in which the side arm opposite the wedge is provided With an opening to receive the projecting end of a pin extending through an adjacent fish plate whereby to prevent longitudinal movement of the rail chair.

3. A rail chair comprising a base adapted to receive a rail flange and having side arms, one of Which is adapted to lie parallel with the Web of a rail and the other of which extends at an angle thereto 'to provide a Wedge shaped space thereloetween, said last mentioned side arm being provided with a plurality of openings adapted for the passage of securing pins into said rail.

In testimony whereof I afiix my signature in presence of two Witnesses.
