2 Claims.
The present invention pertains to a novel joint for the ends of rails in a railway track.
One of the objects of the invention is to provide an effective joint of this character wherein the space occurring between the rail ends is properly filled by parts of the joint pieces, at the same time allowing for the expansion and contraction of the various parts in response to changes in temperature. Consequently, certain parts of the joint pieces must enter between the rail ends, and the invention further provides for proper bearing surfaces between these intervening members. Still another object of the invention is to provide means to facilitate the assembly of the parts before they are finally secured together.
In the accomplishment of these objects, there are provided similar joint pieces adapted to engage opposite sides of the rails to be joined. The ends of the rails are maintained. a considerable 20 distance apart, and the upper edges of the joint pieces are formed with triangular heads adapted to engage one another and form a rectangle filling this space and constituting a continuation of the tread of the rail. In order to furnish sufficient 25 bearing surfaces for the parts inserted between the rail ends, the joint pieces are formed with oblique cheeks beneath the heads, the faces thereof contacting one another.
Each rail end and the joint pieces at opposite 30 sides thereof are apertured to receive tie bolts. To facilitate bringing these respective openings into alignment, each joint piece is formed with a peg adapted to enter another opening in the adjacent rail. After assembly in this manner,
35 the bolt holes are in alignment, and the bolts are readily inserted and tightened. In each set of three aligned bolt holes, one hole is elongated lengthwise of the rail to permit expansion and contraction under temperature changes.
40 The invention is fully disclosed by way of example in the following description and in the accompanying drawing in which Figure 1 is a perspective view of a joint made according to the invention;
45 Figure 2 is a perspective View showing one of the joint pieces and one rail end;
Figure 3 is a perspective view of one of the joint pieces;
50 Figure 4 is a sectional view of a rail showing the end pieces in elevation;
Figure 5 is a horizontal section of the parts 11 lustrated in Figure 2, and
Figure 6 is a horizontal section of the complete 55 joint in the plane of the tie bolts.
Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.
As shown particularly in Figures 1, 2, and 4, the joint is made by means of two like joint pieces I and 2 at opposite ends of the rails 1-3 and 4 that are to be connected. The ends of the rails are spaced slightly to accommodate certain parts as shown in Figures 1 and 6 and as will be described more fully below. The bottoms of the pieces l 10 and 2 meet beneath the bases of the rails as indicated by the numeral 5 in Figure 4. The webs 6 of the joint pieces have their upper ends sloped at 'I to engage beneath the heads of the rails 3 and 4 as also shown in Figure 4.
In substantially the central part of each upper edge 1 is formed a flat triangular head 8 having its two outer edges forming a right angle and its oblique edge disposed inward. These members on the two joint pieces I and 2 are so arranged that their oblique edges engage one another in the assembly to form a rectangle filling the space between the ends of the rails as clearly illustrated in Figure 1. Beneath each head 8 is formed an oblique cheek 9, these members contacting one another in the assembly to provide adequate bearing or contact surface beneath the heads 8 as shown in Figure 6.
Each web 6 is formed with two oval openings it at one side of the cheek 9 and with two round holes H at the other side of the cheek. Between the holes H is a peg I2 for a purpose that will presently be described.
The groove l3 that receives the bases of the rails has a tooth l4 projecting inward from its lateral wall, as shown in Figure 5, and engaging a notch l5 formed'in the adjacent rail base. This construction prevents the rail from slipping away from the joint piece, or vice versa, after the joint has been assembled. 40
The holes I0 and II of each point piece come into alignment with the holes H and Ill respectively of the other joint piece when the pieces are assembled at opposite sides of the rail. Between these holes, the webs of rails are apertured at it so that bolts Il may be passed through each set of three holes as illustrated in Figure 6. The joint pieces are clamped. to the rails between the heads It at one end of each bolt and the nuts l9 at the other end. It will be seen that proper alignment of the holes in the rails and joint pieces is attained by means of the pegs l2 entering certain of the holes I6 in the rails.
The bases of the joint pieces are formed at the outer edges with notches 2i? for receiving spikes driven into the ties or sleepers to anchor this part of the rail.
Each of the bolts IT is received in at least one oval opening [0 which allows expansion or contraction of any of the parts in response to temperature changes.
Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made Without departing from the scope of the invention, as indicated by the appended claims.
What we claim is:--
1. A rail joint comprising two like pieces adapted to engage opposite sides of the rails to be joined, each piece having at its upper edge a horizontal triangular head adapted to enter the space between the rail ends, oblique cheeks formed on said pieces beneath said heads and engaging one another on their oblique surfaces, said heads forming a rectangle filling said space and constituting a continuation of the heads of the rails, and means for securing said pieces to said rails.
2. A rail joint comprising two like pieces adapted to engage opposite sides of the rails to be joined, each piece having a channel adapted to receive one side of the base from each rail, each piece having at its upper edge a horizontal triangular head adapted to enter the space between the rail ends, oblique cheeks formed on said pieces beneath said heads and engaging one another on their oblique surfaces, said heads forming a rectangle filling said space and constituting a continuation of the heads of the rails, and means for securing said pieces to said rails.
