To all 'whom 'it may concern:

Be it known that I, WILLIAM KAYLOR, a citizen of the United States, residing at Muskogee, in thev county of Muskogee and State of Oklahoma, have invented certain new and useful Improvements in Railway- Rails and Joints; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway rails and joints, and more especially to those wherein the ends of the rails interlock; and the object of the same is to produce a rail joint wherein the rail ends are connected both by their interlocking and by means of a plate or chair, without the necessity for any bolts. This object is accomplished by the construction hereinafter more fully described and claimed, and as shown in the drawingvherein* Figure 1 is a side elevation of the two ends of meeting rails which are connected by this improved joint and spiked to two adjacent ties. FigF 2' is a plan View of the same. Fig. 3 is a central longitudinal sectional view of the same. Fig. 4 is a vertical cross sectional view taken on the line 4-4 of Fig. 3. Fig. 5 is a detail perspective view of the chair or plate. Figs. 6 and 7 are similar views of thekey-end and the slot-end of two adjacent rails.

In the drawings the letters A. and B designate two rails whereof the former is the key-end and the latter the slot-end of the rails themselves, and the letter C designates the plate or chair upon which these meeting ends rest when in place over the ties T. The latter may be of wood of any preferred construction forming no part of the present invention. The chair may be and by preference is made of about three-eighths sheet metal rolled into shape as described, although it could be cast or wrought. It comprises a base plate l which may have notches 2 in its edges disposed as shown or elsewhere and obviously for the passage of spikes; and through the base are formed holes 3 for the passage of other spikes, these holes being disposed at certain points as will be described below. Throughout most of the length of this base and forming a part thereof are upright flanges 4 rising therefrom and constituting a substantially U-shaped member or clamp whose sides converge slightly toward each other and are provided along their upper edges with inturned lips 5 for a purpose to appear.

Each rail throughout most of its length which need no further description; and near each end of the rail of either construction the web is thickened as at 1() and the base is widened as at 11 so as to produce a shoulder 12 on either side, these enlarged portions extending from the shoulder completely to the end of the rail if it be the slotJ end as shown in Fig. 7 or about half way to the end of the rail if it be the key end as shown in Fig. 6. Longitudinal grooves 13 in the outer faces of the thickened portions 10 at both sides thereof, are also com.- mon to both kinds of rail-ends, these grooves being for the close reception of the lips 5 of the flanges 4. The shoulders 12 at the inner ends of the widened portions 11 are so disposed that when spikes are driven through the holes 3 into the ties T, said spikes will rest against the shoulders and the inner ends of the wider portions of the faces and hold the rail-ends together while also holding all parts down upon the ties, although the spikes within the notches 2 serve the latter purpose in addition if they are used.

The key-end of the rail has its tread extended as at 20y beyond the point 21 where tegral with said extended tread 20 is a tongue 22 having a beveled extremity 23 for a purpose which will appear. Also there is formed integral with the end 21 of the base a lip 24 whose extremity is beveled as at 25. Finally, there are formed along both sides of the tread 20 where it is extended beyond the ordinary tread of the rail, two anges 26 which reach throughout its length.

The slot-end of the rail is cut off as at 30 short of the end 31 of its base and the same distance therefrom as the tread of the other rail is extended at 2O beyond the end 21 of its base, said cut-0E portion 30 being undercut as at 33 to receive the beveled extremity 23 of the tongue 22. The thickened sides 10 of this rail-end are formed with a groove 32 between them for the reception of the tongue 22, and the end 31 is undercut as at 35 for the reception of the beveled extremity 25 of the lip 24. Finally, the rail-tread is provided yon its two opposite sides with flanges 36 which terminate on a line flush with the cutsoft' portion 3() as seen in Fig. 7. All

comprises the usual tread, web, and baseV its base ends, and beneath and formed inparts of both rail-ends are formed integral in the act of-making the rail, and it is my in-v we are now to consider, first the plate or4 chair shown in Fig. 5 is slipped' partway onto the rail which is partly spiked, the lips 5 of its flanges closely engaging the grooves 13 in a manner which will be clear and the disposition of the rail joint being such that the chair when in place will come above two of the ties. Next the complementary end of the next rail to be applied is brought into position and` its grooves 13 engaged with the projecting ends of the lips 5 and slipped into the clamp 4L until the end of its extended tread 20 comes against the cut-off tread portion 30 of the other rail, at which time the ends 21 and 31 of the two bases will come together. As the rail-ends interlock the beveled extremities 23 and 85 engage the undercut portions 33 and 35 and the ends of the flanges 26 come against the ends of the flanges 36. Thus the tongue 22 is caused to lie within the groove 32 and the two railends are interlocked in a most thorough manner and over a considerable distance. By preference the proportion of parts is such that the clamp 4 is ust about as long as the thickened portions of the two rail-ends,

while the base plate 1 is a little longer, and

the holes 3 in the latter are so disposed that when the spikes are driven through them into the ties their heads will stand behind the shoulders 12 of the webs and across the inner ends of the widened portions 11 of the treads of the two rail-ends so that the latter are absolutely prevented from moving apart although permitted to have a slight expansion and contraction due to changing temperatures.

Thus it will be seen that I have produced an improved rail oint wherein nobolts are employed and there are no nuts to come loose, wherein the rail-ends are always in alinement both vertically and transversely7 and wherein such alinement in both directions is assisted by the chair and its clamp; and especial attention is directed to the fact that the insertion of the spikes which are necessary to hold the chair to the ties is all that is required to hold the rail-ends from separation from each other. I have not given the dimension of parts because that is .not important to this invention. It will be observed that the flanges 26 upon the keyend overlie the upper edges of the sides 10 of the slot-end so that no water or snow will get into said slots and cause the rail ends to rust together, and so that dust and dirt are effectively excluded.

Vshat is claimed as new is:

1. In a rail joint, the combination with two rails whose ends are thickened and formed so as to interlock when they meet and having registering longitudinal groovesb along the opposite sides of their thickened portions; of a chair comprising a base plate,

u )rioht flanges risinO therefrom alonOside b D D C said thickened portions, and inturned lips along their upper edges closely engaging said grooves. Y

2. In a rail joint, the combination with two rail-ends which are widened toward their extremities so as to produce shoulders and are adapted to interlock; of a chair comprising a base platev having spike-holes through it at points adapted to stand behind said shoulders whereby the spike heads will 8'5 engage the latter, and a clamp on said plate engaging the sides of the widened portions.

3. The herein described rail joint comprising a key member and a slot member, the

key member having its tread portion extended beyond its base portion, a lip on t latter having a beveled extrem-ity, and a tongue extending along the/lower side of the extended tread and having a beveled extremity; and the slot member having its tongue, the cut-off portion of the tread and the end of the base being undercut for the reception of said beveled extremities.

4L. In a rail joint, the combination with a chair having a clamp; of the rail-ends whereof one has its tread portion extended'105 beyond its base portion and provided with a depending tongue, and the other has its base portion extended beyond its tread portion and provided with a groove for'the reception of said tongue, and laterally projecting flanges along both sides of each tread portion terminating flush with the end thereof so that the extremities of the flanges Yabut against each other when the rail-ends are assembled upon said chair and the top of said groove is protected.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM KAYLOR.
