RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 633,133, dated September 19, 1899.

Application filed March 21, 1899. Serial No. 709,901. (No model.) I

T0 all whom it may concern:

Be itknown that I, ASA IV. GRIFFITH, acitizen of the United States of America, residing in Wilmington, in the county of New Castle, in the State of Delaware, have invented a certain new and useful Improvement in Rail- Joints, of which the following is a true and exact description, reference being had to the accompanying drawings, which form apart thereof.

My invention relates to the construction of rail-joints, and has for its object to provide a firm and strong joint for securing together the ends of railway-rails.

The nature of my invention will be best understood as described in connecti'on with the drawings in which it is illustrated, and in which- Figure 1 is a cross-section through the cen- A indicating the rail-Webs pierced with holes a for the fish-plate bolts.

A2 indicates the rail-base, a2 a2 indicating the upper faces of the base.

B B are ties.

O O are iish-plates, formed, as shown, with an upper flange O', pierced with bolt-holes c', corresponding to the bolt-holes a' in the railweb, an intermediate iiange or center C?, adapted to fit on the upper faces CL2 of the railbase, and a lower flange C3, extending belo'w the rail-base, provided with bolt-holes cB and with an inwardly-extending lug C( at their lower edges. Preferably the iianges O3 are only formed in the center of the fish-plates C and of a length which will permit them to extend between two adjacent ties B, over which will extend the lianges' O and center C2, as

, shown.

D is a U-shaped section of a length corresponding to that of the anges CB and formed so that when the face d of its central partabuts against the bottom of the rail-base its lateral arms D2 will extend down over the lugs C4 of the flanges C3, against which the ends of said arms should rest when the joint is fully erected. Preferably I form the face d' 0f section D with a slight convex curvature and form the section as a whole, so that its arms D2 will not actually Contact with lugs O4 until the flanges C3 of the {ish-plate and arms D2 of the section D are drawn together by the bolts E', which are passed through oppositely-lying holes d2 and c3 in arms D2 and anges C3 and made to draw the part-s into contact by means of the nuts e.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. A rail-joint having in combination two fish-plates O O formed with iianges C3 extending below the rail-base and formed with inwardly-extending lugs C4 at their lower edge, a U -shaped section D adapted to tit below the rail-base and having its arms D2 extending over the lugs C4 of the fish-plates, bolts as E securing the upper .flanges of the fish-plates together and to the rail and two series of bolts E securing t-he flanges C3 ofthe fish-platesto the adjacent arms Dof the section D.

2. `A rail-joint Vhaving in combination two fish-plates C C formed with flanges C3 extend- 'ing below the rail-base and formed with inwardly-extending lugs O4 at their lower edge, a U-shaped section D having a convexlycurved face d/ adapted to it below the rail'- base andhavingits arms Dgext'ending overthe lugs O4 ofthe fish-plates, bolts as E securing the upper flanges of the fish-plates 'together and to the rail and two series of bolts E securing the flanges C3 of the fish-plates to the 'adjacent arms D2 of thesection D.

A. IV. GRIFFITH.
