Specification of Letters Patent.
' Patented Nov-29,1910.
Application filed Iebruary 1o, 1910. Serial no. 543,088.
Be it known that I, GEORGE W..] tonnn-zs, a. citizen of the United States, resldlng at Laurel, in the county of Koochiching, State.
of Minnesota, have invented certain new and useful Improvements in Rail-Jolnts; and I do hereby 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. V w
This invention relates to rail joints, of that general class commonly known as scarf joints, and has for an object to so construct the rail ends that. their interfitting or engaging portions will be simpler in construction than heretofore.
Another object of the invention is to provide the end of a rail with engaging portions that may be formed by a sultable die before the heated rail in the manufacture has become cooled.
A still further object is to provide a scarf 7 joint the members of which'will have their interlocking means reinforced in a more positive manner than usual.
To attain the above ends my invention consists of certain novel details of construction and combination of parts which will be hereinafter .more claimed.
In the accompanying drawingsforming part of this specification, F' e '1 is a perspective -view of a railway oint formed in accordance with my invention. Fig. 2 is a detail perspective view of one of the joint members. Fig. 3 is a detail perspective view of the other member of the oint. Fig. 4; is a transverse sectional view through the joint. v
Referring now to the drawing in which like characters of reference designate similar parts in the views shown 5 and 6 desig-' nate the meeting ends of two adjacent rails.
The extreme end of one rail is mutilated as shown, one side of its head, web, and flange being cut away to approximately the middle vertical diameter of the rail to provide a lateral rabbet 7 equal in size to approximately one-half the cross dimension of .the parts. The projecting portion 8 of each rail formed by this mutilation of the rail end projects into the lateral recess 7 of the process of fully described and mating rail'end, the extreme'end'face 9 of said projecting portion be disposed in abutting contact with the end ace 10 of said rabbet. p
A locking lug 11 projects Iforwardly from the end face'of. each projection .8 and engages in a recess 12 formed in the end face .10 of the rabbet. formed in the mating rail end, this locking lug preventing the ver-' tical displacement of either of the rail ends and thereby obviatingthe liability of'a low olnt.
It is evident that the mutilation of the opposite ends of a rail maybe formed by a single die, care being taken to so reverse the rail during the o eration so that the rabbets at each end of. t e rail will be on opposite sides thereof, and that the mutilatlon of each rail end is of such a simple character that the rail while still hot may be advanced intothe die andformed with the above de scribed mutilated end before it has become cooled, and therefore the machining and finishing of such common necessity 1n the formation of scarf jointsas hitherto constructed, entirely obviated.
A pair of fish plates 13 are bolted as shown at 14 to the rail webs and are sulficient in length to extend considerably beyond the interfitting portions of the rail ends so that a tight connection'between the parts may be maintained atall times.-
In addition to the above lockin means be tween the abutting rail ends the1ase flange of one of the rails is cut away on its bottom face to. rovide a rabbet 15 which engages a forwar y rojecting extension 16 dlsposed on the end ihce of the rabbet of the opposite rail flange. These interfitting portions of the rail base flanges serve .to reinforce the interlocking means between the rail ends and as .the bottom edges of the fish plates bear against the top surfaces of the interfittin flanges a vertical displacement of the rai ends is prevented by 'thefish plates should the said interlocking means become broken.
From the fore oing description taken in connection with t e'accompanying drawing,
changes in the form and proportion may be made within the scope of the appended claim. a
What is claimed is r In .a rail joint, interfitting rail ends each having a side portion of its head and web removed, one of said rail ends having a side portion of its base flange removed, the
remaining side port-ion of said rail base flange havin its under side cut away hori- 'zontallyi2h an the (fiber-f oi said rail ha euppersieotecorrespon'g half 0% its base flange cut away horizontally,
