RAIL JOINT.

Application filed July 3, 1826, Serial No. 120,496, and in Canada July 3, 1925.

The present invention pertains to a novel rail joint and support designed to provide a firm and secure connection between the ends of two rails or support such rails between joints.

The principal feature of the invention is the provision of ajoint or rail support embodying a wedge which binds against a clip secured to the railway ties and also against the base of the rail or rail ends.

Accordingly, the clip comprises a base member on which the rail or rail ends are laid. From this base extend tongues which overlie the base of the rails. Between the base and one or both of the tongues is driven a wedge-like member which is further held in position by another locking device. The latter preferably comprises notches formed on the wedge in conjunction with a locking pin driven through the tongues and into engagement with the notches. A further feature of the invention is the provision of springs which bind the locking pins against the teeth. 7

Another object of the invention is to attain a rail joint or support which will. not require the use of bolts and consequently will be capable of rapid installation.

The invention is fully disclosed in the following description and in the accompanying drawings in which:

Figure 1 is a perspective view of a rail joint constructed in accordance with the invention;

Figure 2 is a side elevation thereof;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a perspective view of the key;

Figure 5 is an elevation of the locking pin;

Figure 6 is a section on the line 66 of Figure 5;

Figure 7 is a perspective view of a rail support to be used between the joints; Figure 8 is a transverse section thereof showing how the rail is inserted within this support; and

Figure 9 is a perspective view of the key.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 is shown a pair of rails 1 having their ends brought together on a railway tie 2. The ends of'the rail are placed upon a clip comprising a base 3 and a pair of longitudinal tongues 4. Between each tongue and the web 5 of the rail is inserted a locking key consisting of a wedge portion 6 and an upright flange 7 on which is formed a rib 8. The edge of the tongue is disposed beneath the corresponding rib, as clearly illustrated in Figure 3. The wedge '6 has a plurality of teeth 9 cut in its edge, and the remainder of the edge is sloped as at 10, whereby t-he'key may be firmly driven between the web 5 and the corresponding tong-L164.

Each side of the clip is loosely held by means of a pair of spikes 11 driven into the tie 2 so that the clips may he slid to permit removal of the rails. The clip is formed with one or more apertures 12 lying at the edge of the wedge when the latter is in place. Into each such aperture is inserted a locking pin 13 having a socket 14 near its lower end. In the socket is received a spring 15 which bears also against the adjacent wall of the apertures 12. Near its upper end the locking pin is formed with a pocket 16 which has a sloping bottom 17. As the wedge is driven into place, each tooth 9 passes the pocket 16 until the wedge is driven to the desired extent. At this time one of the teeth 9 bears against the slanted surface 17, and the pin is held against the wedge by the spring 15.

When it is necessary to remove one of the rails, as in case of repairs, it is only required to swing the locking pin in the direction of the arrow shown in Figure 3 and to hold it there while the wedge is removed. It will thus be seen that no bolts passing through the rail are required in the assembly of this joint.

The base 3 has also-another aperture 18 positioned near the lower edge of one of the tongues 4 for receiving a spike when thejoint is made on a curve. The spike. in this position, being nearer the rail, retains it more firmly than when the spike is driven at the edge of the clip.

In the rail support illustrated in Figures 7, 8 and 9. one of the tongues 20 on the base 21 is smaller than the other tongue 22. The tongue 20 is constructed to fit closely and directly against the rail base 28. The tongue 22 is appropriately tapered towards one end. and formed internally for the reception of a locking wedge 24. This member is provided with a lip 25 which lies over one edge of the base 23 as shown in Figures 7 and 9. One

edge of the wedge is formed with teeth 26 engaged bya pin 27 driven through an aperture 28 in the tongue 22 in the manner described above.

In the assembly of the device, the clip 2022 is rigidly secured to the tie 2 by means of spikes 29. The space between the tongues 20 and 22 is of sufficient width to receive the base of the rail 1. The rail is fitted against the tongue 20, and the wedge 24 is driven into the space between the rail base 23 and the tongue 22 to engage the pin 27 asalready stated.

\Vhile a specific embodiment of the inven tion has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims. I

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent'is:

1. A rail joint or support comprising in combination with a rail, a clip on which said rail is disposed, said clip having tongues overlapping the base of said rail, a wedge driven between one of said tongues and said base said wedge having teeth outin one of its edges, a locking pin driven through said tongue and adapted for engagement with said teeth, and a spring pressin said pin against said teeth.

2. A rail joint or support comprising in combination with a rail, a clip on which said rail is disposed, said clip having tongues overlapping the base of said rail, a wedge driven between one of said tongues and said base, said wedge having inclined teeth out in one of its edges, a locking pin driven my hand.
