PATENT OFFICE RAIL JOINT,

Application filed April 30, 1923. Serial No. 635,682.

To all whom it may concern:

Be it known that I, WILLIAM G. WILSON, a citizen of the United States, residing at West New Brighton, S. 1., in. the county of Richmond and State of New York, have invented new and useful Improvements in Rail Joints, of which the following is a specification.

This invention relates to rail joints and is an improvement over my Patent #1370; 290, granted to me on March 1st, 1921.

The principal object of the invention is the provision of a rail joint for preventing creeping of the rails in the direction of travel of the rolling stock wnile the same is passing over the rails connected thereby.

Another object of the invention is to provide a rail joint for rigidly and securely connecting the meeting ends of a pair of rails, and a means for bracing the joint against a tie for preventing the movement of the oint in one direction, without effect ing the various stages of expansion and contraction of the rails.

A further object is to provide a rail joint with a rigid brace for co-action with the tie of a road bed.

lVith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawing, in which Figure 1 is a side elevation of my improved rail joint as connected to the meeting ends of a pair of rails.

Figure 2 is an enlarged bottom plan view of the same. Y

Figure 3 is a vertical transverse sectional view on the line 33 of Figure 1.

Figure 4; is a similar view on the line 1- of Figure 1.

Figure 5 is a detail perspective view of one of the chairs.

In the present type of rail joint, it is a tendency of the same to creep in a direction of the trend of travel of the rolling stock. This action is caused by the forward thrust due to the load and speed of the rolling stock and is very damaging to the joint so as to cause the looseningof the nuts and ofttimes bending and breaking of the bolts My invention is therefore intended to overcome'these objections'as will be apparent from the description. I

Referring more particularly to the drawing, the reference numeral 10 designates meeting ends of a pairof rails which are of the usual well-known construction and having their webs provided with longitudinal slots 11 for receiving fastening elements about to be described.

The rail joint includes a pair of chairs 12 and 13 adapted to be secured to opposite sides of the rails 10. The construction of the chairs 12 and 13 igidentical, so that a description of one will suflice for the other. Each chair includes an angle bar or fish plate 14, provided with a plurality of open ings 15 adapted to register with the slots 2 11 in the rail for receiving the bolts 16.

Each angle bar 14 is formed with an angularly disposed portion 17 adapted to overlie the base of a rail, and the edge of said portion 17 may be notched as at 18 for ac commodating spikes l9 employed for holding the chairs 12 and 13 in engagement with the ties 20. Intermediate the ends of the chairs, the same are each formed with a horizontally disposed seat 21, having depending therefrom suitable lugs or end walls 22, connected together by inner and outer strengthening webs or side walls 23. The outer side wall 23 is formed at its top with a bead 23' and serves to strengthen the walls at their point of formation with the portion 17 of the angle bar 14;. Connecting the side walls 23 of each bar is a sleeve 24, provided with atransverse bore 25. When the chairs are in their proper position upon the rails, the inner side walls 23 of the chairs are adjacent each other, and thebores 25 in alignment, after which a fastening element in the nature of a bolt 26 is passed through said bores, and a nut 27 threaded to the free end of said bolt for securely holding the chairs together at a point beneath the base of the rail. With reference to Figure 1, it will be seen that the depending walls are interposed between a pair of ties and one of the lugs or end walls 22 in contact with the longitudinal side edge of the tie. We shall presume that trend of travel of the rolling stock on this particular rail, is in the direction as shown by the arrow in Figure 1. A tendency of the joint by reason of the for-- ward thrust of the rolling stock will also be in the same direction as indicated by the ar :row, but as one of the end walls of each chair is in intimate contact with the tie, no creeping movement is possible. By providing the webs of the rails 10 with slots the rails are free to expand or contract without moving the chair so that certain of the walls 22 are always in engagement with one of the ties. It will ofcourse be'understood that if the trend of travel of the rolling stock were in the opposite direction, the othor end of the end walls 22 would be in contact with the other tie and the stress would be taken up by that particular tie.

From the above description it will be seen th'atl have provided a rail joint made up ofa pair of chair members which are identical in construction, and which are unlike many joints of this type wherein a right and left chair is employed for each joint.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do: not limit myself to the exact details of construction herein set forth 1101' to anything less than the whole of my invention limited only by the appended claim.

What is claimed as new is The combination with the meeting ends of a pair of rails provided with parallel arranged slots, a pair of chairs designed to embrace the ends of the rails and being provided with openings registering with the slots, a seat formed on each chair midway its ends for receiving the base of the rails, longitudinally disposed side walls arranged in. pairs and depending from the seat, a bead formed at the juncture of the outer side wall with the chairs, a sleeve traversing each pair of side walls and being provided with a bore registering with openings formed in the side walls, end walls connecting the side walls and adapted to engage a tie, securing means passing through the bores and openings of the depending side walls for securing the chairs in operative relation, and said chairs being provided with notches disposed adjacent the seat on one side thereof and adjacent the end of the other side.

In testimony whereof I have aflixed my signature.

' WILLIAM G. VII/SON.
