2 Claims. 238192) This invention relates to improvements in rail joints.

The primary object of the invention is to provide a rail joint seat formed of duplicate sections which interfit and embrace the base and web portions adjacent the meeting edges of rails.

A further object of this invention is to provide a rail joint seat of the above mentioned character having complementary interfitting parts adapted to be locked in position against displacement by means of the joining bolts as well as the rail spikes.

A further object of this invention is to provide a rail joint seat of the above mentioned character which will positively prevent separation of the rails with the resultant accidents to rolling stock of both the passenger and freight types and which will not be thrown out of alignment by contraction and expansion of the rails during season changes.

Other objects and advantages of the invention will become apparent during the course of the following description forming a part of this specification and in which:

Figure 1 is a perspective view of the rail seat joint embodying this invention, showing the same applied to the meeting edges of a pair of railroad rails;

Figure 2 is a horizontal cross-sectional view taken on line 2-2 of Figure 1, looking in the direction of the arrows, illustrating the manner in which the rail joint seat embraces the web portion of the rail end and showing the manner in which the overlapping sections of the rail joint seat members are locked in place by means of bolts;

Figure 3 is a vertical cross-sectional view taken on line 3--3 of Figure 1, looking in the direction of the arrows, illustrating the manner in which the overlapping extensions engage the web portion of the rail and partly enclose the base portion thereof; and

Figure 4 is a perspective view of one of the rail joint seat members illustrating the base engaging member and the web confining portion.

In the drawing, wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughout the same, the reference character 5 will generally be employed to designate a rail joint seat adapted to join together the ends of the abutting rails B and l.

A pair of rail joint seats 5 are employed for effecting the connection of the two rail ends 6 and I and each rail joint seat comprises a base member 8 having vertical portions 9 and I0 along the outer edges thereof. The vertical portion 9 extends inwardly as at l I to conform to the upper portion of the rail base l2 and extends upwardly as at l3 to embrace the web portion of the rail web l4. The vertically extending web embracing portion l3 terminates directly under the tread of the rail designated by the reference character I5.

The other vertically extending base portion [0 is inwardly bent as at Hi to embrace the upper surface of the rail base l2 and then extends upwardly as at I! to abut against the web l4. A portion of the vertical base section III is cutaway as at 18 to receive a complementary cutaway portion l9 formed on the vertical base portion 9. In this manner the rail joint seat 5 may interfit so that the inwardly bent portion ll of the vertical section 9 may overlap the cut-away portion 18 of the vertical base section Ill.

The construction above described also allows the web embracing portion l3 to overlap the joint between the rail ends 6 and 1 on alternate opposite sides of the rails.

When the rails are placed in abutting position as shown in Figure 1, a pair of rail joint seats 5 are arranged so that the web embracing portions I 3 engage opposite sides of the rail web l4 so that bolts 20 may be passed through openings 2| formed in the web embracing portion l3 and anchored by means of bolts 22.

To further lock the rail joint seats 5 against displacement, cut-outs 23 are formed in the vertical base portions 9 and ID for receiving rail spikes having heads which are larger than the width of the opening 23 in order to insure proper anchorage of the base sections 9 and I0.

Since the rail base sections 5 are complementary it will be understood that two rail base joints 5 are required to consummate an adequate connection between the abutting portions of the rail and that various changes in the shape, size and arrangement of the sections may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. A rail joint comprising in combination with the meeting ends of rails, a pair of duplicate chair members, each chair member including a base plate and upstanding side flanges for intimate contact with the base flanges and webs of the distance equal to the distance or the cut-away side flanges and terminating in vertical planes and with the relatively long and short side flanges abutting at each side of the meeting rail ends at points inwardly oi the abutting ends of the base plates and rail ends seated'in said chair members with their meeting ends in vertical alinement with the abutting ends of the base plates and in a plane intermediate of and parallel with the abutting ends of said flanges.

2. A rail joint chair, comprising in combination with the meeting ends of rails, a pair of duplicate chair members, each chair member including a base plate and upstanding side flanges for intimate contact with the base flanges and webs of the rails, corresponding side flanges of each chair member terminating in inwardly spaced relation to the abutting ends of the base plates and in vertical planes and the other corresponding side flanges extending beyond the abutting ends of the base plates and terminating in vertical planes a distance whereby the flanges at each side of the chair members and the adjacent ends of the base plates abut with each other when the base plates are assembled with the point of engage ment between the rail'ends being between the points of abutment of the flanges, rail ends seated in said chair members with their abutting ends in vertical alinement with the abutting ends of the chair members and anchor means for the rail ends passing through the rail ends and overlapped ends of the side flange extensions.

MIKE 'MITIN.
