RAIL JOINT.

WITNESSES DAVID TERREL, OF DEGRAFF, OHIO.

RAIL-JOINT.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed August 22, 1911. Serial No. 645,357.

To all whom it may concern:

Be it known that I, DAVID TERREma citizen of the United States, residing at Degrafi, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

work loose owing to the constant vibration ofthe rails produced by the passage of rolling stock thereover.

With these and other objects in View, the invention consists in certain combinations and arrangements of theparts as will more fully appear as the description proceeds, the

novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which: Figure 1 is a top plan view of a railjoint ,constructed in. accordance with the inven- "tion; Fig. 2 is a transverse sectional view through the same on the line 22 of Fig.

1; Fig. 3 is a detail perspective View of one end of the interposed rail section; Fig. 4 is a plan view showing a modified construction of the joint; Fig. 5 is a similar view showing a still further modification; Fig. 6 is a transverse sectional view through the joint; and Fig. 7 is a vertical sectional view on the line 7-7 of Fig. 6.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the preferred embodiment of the invention, the numerals 1 designate a pair of rail ends, and 2 a rail section which is interposed between the said rail ends. The rails may have anystand'ard or conventional cross section, althoughf at the extremitiesthereof the webs are thickened, as indicated at 1% so as to have. sub-:

stantially the same thickness as the rail heads. A vertically disposed tongue 3 projects longitudinally from each end of the rail section 2 and terminates in a head 4, the said head being substantially cylindrical in shape and gradually tapering in thickness toward the lower end thereof. \Vhen the intermediate rail section 2 is slipped vertically into position from a point above the rails, the tongues 3 and heads 4 are received within corresponding'sockets 5 in'the rail ends 1. An interlocking connection is there by produced which holds the rails securely against both lateral and vertical displacement, and owing to the tapered formation of the heads 4, they have a wedge engagement with the sockets 5. An angle shoe 6 may be applied to one side of the joint and a joint bar 7 fitted against the opposite side of the joint, the various members being connected in the usual manner by means of bolts 8. The base plate 6 of the angle shoe 6 is preferably transversely corrugated as indicated more clearly in Fig. 7 so as to form a rigid support for the rail ends. The

angle shoe and joint bar hold the interposed rail section 2 securely against vertical displacement, and as long as this interposed rail section is in position, the rail ends can niaithgr pull apart nor become relatively disp ace A modification is shown in Fig. 4 in which the ends of the interposed rail section. 2 are provided with dove-tail tongues 9 which engage corresponding sockets in the rail ends. A, still further modification is shown in Fig. 5, in which the interposed rail section- 2* is provided with T-shaped tongues 10 engaging corresponding sockets in the rail ends. The operation of these modified joint constructions is substantially the same as that previously described.

Having thus described the invention, what I. claim as new and desire to secure by Letters Patent, is:

1. In a rail joint, the combination of a pair of rail ends having vertically disposed sockets therein, the inner ends of thesockets being enlarged, a. rail section interposed between the rail ends and provided with vertical tongues adapted to be slipped into the sockets from the top thereof, 'thesaid tongues terminating in enlarged heads fitting in the enlarged bases of the sockets so as to hold the rails against pulling apart, and joint bars "applied to the sides of the rails for holding the interposed rail sections in position.

2. In a rail joint, the combination of a pair of rail ends provided with vertically disposed sockets opening through the top thereof and tapering toward the bottom of the rails, the bases of the said sockets being enlarged, a rail section interposed between the rail ends and provided at the ends thereof With Vertical tongues adapted to enter the sockets of the'rail ends from the top thereof said tongues terminating in heads engaging the enlarged bases of the sockets to hold the rails against pulling apart, an-

angle shoe applied to one side of the joint and forming a. base plate extending under the joint, and a joint bar applied to the opposite side of the joint.

In testimony whereof I affix my signature in presence of two Witnesses.
