RAIL JOINT.

Application iiled January 31, 1922. Serial No. 533,036.

To all who/m. 'it may concern Be it known that we, MATT CAnAriN. and FRANK Nnvis'rrorr, citizens of the United States, residing at ylerry, in the county of Lawrence and State of South Dakota, have invented new and useful improvements in Rail. Joints, of which the following is a specification.

The invention relates to improvements in rail joints.

The object of the present invention is to improve the construction of rail joints and to provide a simple, practical and efficient rail joint of strong, durable and comparatively inexpensive construction adapted to eliminate fish plates, angle bars and similar connecting means and capable of securely interlocking the contiguous ends of adjacent rails and of enabling the same to be securely spiked to the cross ties.

A further object of the invention is to pro-y vide a rail joint of this character equipped with male and female interlocking` ends capable of effectually preventing lateral and longitudinal separation of the rails and of permitting the necessary expansion and contraction of the same and also enabling the rails to be readily separated and removed when the spikes are withdrawn.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accon'ipanying drawings and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages vof the invention.

in the drawings, in which like characters of reference designate corresponding parts in the several. views Figure l is a side elevation of a rail joint constructed in accordance with this invention.

Figure 2 is a central longitudinal sectional view of the same.

Figure 3 is a horizontal sectional view of the rail joint.

Figure 4 is a perspective view of the male section of the rail joint.

Figure 5 is a similar view of the female section of the rail joint.

1n the accompanying drawing in whichy longitudinal tongue t and it has an eX-y tended base 5 recessed at opposite sides of the tongue 4 and presenting broad bearing surfaces and forming shoulders which are arranged in flush relation with the end face 3 of thev laterally enlarged web portion 2. The tongue et which is arranged vertically, is provided at th'etop at its outerl terminal withy an upwardly projecting portion 7 ar ranged in spaced relation with the end face 3 of the laterallyfenlarged portion 2 to' form an intervening recess 8 for interlocking with the female section as hereinafterfully described.

The female section consists of a rail `9 f having its web 10 laterally enlarged at opposite sides at 11 at the endl of the rail and the laterally enlarged portion 11, which is inwardly tapered, is provided in its lower portion with a longitudinal recess 12 arranged centrally of the end of the rail and extending upwardly from the bottom thereof and inwardly from the end of the same. The longitudinal recess 12, which receives the tongue i is provided at the top at the inner portion with a branch or socket 13 which receives the projectionr' of the tongue whereby the male and female sections are interlocked and held against relative longitiulinal movement, suflicient space or play being provided in j nactice to permit the expansion and contraction of the rails. The base 'lfet of the female section 9 extends to the outer end of the late Tally enlarged web port-.ion 11, as shown, and is provided `in, its lower face with bottom recesses 15 located at opposite sides of the longitudinal recess 12 and presenting fiat lower surfaces and inner shoulders 16. The flat faces of the recessed terminal portions of the base of the female sectiony are fitted against the flat upper bearing surfaces orl the extended portion of the base of the male section and the recessing of the base portions arranges ill@ 11191961' and lower aces of the bases 0f the rails in substantially flush relation and provides an intel-fitting or interlocking connection, the shoulders G and 16 cooperating with the end faces of the male and female sections to limit the inward longitudinal movement of the rails.

The female section is adapted to be fitted over the tongue of the male section to interlock the parts and the interlocking of the parts will hold the sections against relative lateral and longitudinal movement and the spikes 'i7 for securing` the male and female seetions of the rails to the cross ties will hold the rails against up 'ard movement so that the rails will be securely held in place Without the employment of iisli plates? angle bars and similar connecting` means. 'lso the interlocled ends of the rails are arranged in overlapping' relation So that the ends of the rails ivill be maintained 'in proper relative position to prevent the pounding' of the Wheels on the ends of the rails due to uneven spacingY or positioning of the same.

Each of the rails if; designed to be provided at each end with one ot the male or female sections and one rail may be proi vided at one end with a female section and i/ieopaa bottom thereof and provided at the top with an upwardly extending` terminal projection, said male section being` inovideL `with an extended base recessed at the upperface at opposite sides of the tongue to. form smooth 'l'lat bearine surfaces and to provide inner shoulders, and an interlocking female seetion having a laterally enlarged inwardly tapered web provided in its lower portion with a longitudinal recess extending` inwardly from the end of the female section and upwardl57 from the lower face of the saine to receive the said tongue and provided at the top at its inner portion with a vortical branch or Socket receiving the terminal lvnojection of the tongue to interlock the serti'isis against relal'i'fe lolug'itui'linal movement, said longitudinal recces and tongue e'ztendiirey upwardly from the l'iettiu'fi the rails and terminating short. ol the head of the saine so as to leave the tread 'fau of the heads unbrol-:en to the end of eaeh rail, and said 'female section being also prf vided with extended base portions recessed at their lower :faces at the bottom of the rail to form smooth unbroken surfaces and fitted upon the flat liearingsurfaces of l'lie male section and forming` inner shoulders, and the said web being; tapered horizontally7 to provide a substantially elongated elliptical ivob formation at the joint and of a 'width nearli7 equal to that of the head of the rails at the ends thereof and graduall)7 decreasing in Width to a point considerably beyond the end of each rail,

In Vtestimony whereof We have hereunto set our hand.

Mr-rr'll CARAPNA. FRANK NEVISTICH,
