NOISELESS RAIL JOINT.

Application led Tunek 8, 1926. Serial No. 114,439.

This invention relates to a joint for track rails of railroads and aims to provide a novel, more etlicient, durable and comparatively inexpensive construction, which will render the joint substantially noiseless.

Various objects and advantages accrue from the present invention as will appear in detail hereinafter in connection with consideration of accompanying drawings of one operative embodiment and the following description.

In said drawings:

Figure 1 is a fragmentary plan view illustrating the joint;

Figure 2 is a side View elevation thereof;

Figure 3 is a detail sectional view taken on the line 3-3 of Figure 1;

Figure 4 is a detail sectional view taken on the line 4-4 of Figure 1;

Figure 5is a detail perspective view of one of the rail ends forming the joint; and

Figure 6 is a plan view of the rail sections at the joint, the same being separated to disclose their structure.

In the said drawings, wherein like reference characters designate like or corresponding parts, 10 are fragments of railroad rails,

generall of the usual cross-sectional contour, in that they have bases 11, webs 12 and treads 13.

Said rails may be secured together in any desired manner as by the fish plates 14 embracing opposite sides of the webs and being removably secured thereto by bolts 15 passing through said webs-and fish plates. The upper edges of the lish plates 14 directly engage the under surfaces, of the treads.

In carrying my improvements into effect, each rail 10 has a tongue 16 extending be yond an end thereof. The inner side surface 17 of each tongue is generally inclined or diagonal as shown and its under surface is truly rectangular with its inner edge coincident with the adjacent side of the Webs 12. Said surface 17 midway of its ends as at 18 is vertical and on a twist so that on one side of point 18, said surface at 19 inclines upwardly and outwardly, and

on the other side as at 20 inclines downwardly and inwardly.

The tread 13 at 21 is out away and inclined and twisted similarly to the surface 17 so as to be intimately itted b v the tongue 16 of the adjacent rail. The diagonal lines of the surfaces 17 and 21 merge into each other and meet centrally of the webs 13 at their meeting ends.

The meeting ends of each rail are similarly formed and due clearance is provided for expansion and contraction of the rails as occasioned by atmospheric conditions.

When the railsl are joined, the tongues 16 tit the portions 13 and rest on the tops of the fish plates 14, the rails being bolted together at 15.

Among the. advantages may be mentioned that, due to the tongues being cut on an angle from near the top of the rail head to the web of the rail underneath, any possibility of wheel flanges climbing at this point or splitting the joint is overcome; the tread or head of the vrail has full bearing the full width on the web of the rail to give the joint maximum carrying capacity and so that in crossing over the joint in the web, the otherI rail has picked up the weight of the car wheel and carries it on the full width of the rail web preventing any rail shock or jar and consequent pounding by passing wheels; tlie receding point being cut on an angle from the outer edge of the rail head to flush with the web of the rail underneath and natural underneath rail head allows the complete point or tongue to have full width bearing upon the. angle iron or continuous joint giving it a tendency to more tightly wedge making a practically solid continuous rail; overcome swaying motion of the train in' passing over alternate joints caused by pounding down of ties at rough joints, and the base of the rail is unaltered and no extra material is needed.

I claim as my invention:

1. Rails having their meeting ends provided with tongues, the inner faces thereof having their base lines parallel to the longitudinal axis of the rail and their top lines diagonal, said faces of the respective rails being substantially flat from one line to the other line, and the rails at portions thereof being cut away in conforming to and receiving said tongues.

2. Rails having their meeting ends provided with tongues, the inner faces thereof having their base lines parallel to the longitudinal axis of the rail and their top lines diagonal, said faces of the respective rails being substantially fiat from one line to the other' line, and the rails at portions thereof being cut away in conforming to and receiving said tongues, and the diagonal lines of the tongues and cutaway portions of the respective rails being in alignment.

3. Rails having tongues' extending beyond the meeting ends thereof, sh plates con- 6 necting the rails, said tongues being intact at the bottoms and resting directly on said fish plates, and the inner surfaces of the tongues being twisted as described, and the rails having cut-away portions receiving and conforming in shape to the inner surfaces of said tongues.

In testimony whereof I afix my signature.

CHESTER A. JOHNSON.
