CURTISS-SUPPORT FOR RAIL-JOINTS.

Specification of Letters Patent.

Patented April 27', 1909.

Application filed October 26, 1908. Serial No. 459,519.

To all whom it may concern.-

Be it known that I, Louis MUELLER, a citizen .of the United States, residing at Owosso, in the county of Shiawassee, State of Michigan, vhave invented certain new and useful Improvements in Truss-Supports for Rail-Joints; and l do 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, reference being had to the accompanying drawings, and to the 'figures of reference marked thereon, which form a part of specification.

This invention relates to a truss support for rail joints, more expressly designed for effecting .a compromise joint between the ends of railway rails of different cross sec tion, and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a joint of the .character described of comparatively simple and inexpensive construction, wherein the arrangement is suoli as to afford a yfirm support for the meeting ends of rails of dierent transverse section,y and at the same time provide for carrying the wave motion of the rails through said joint and obviate wheel blows on the heads of the rail ends by maintaining a perfect surface between the heads ofthe rails ,at the joint.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a perspective view of one side of a rail joint showing the application of my invention. Fig. 2 is a transverse section on line 2 2 of Fig. 1. Fig. 3 is a transverse section on line 3-3 of Fig. l. Fig, 4 is a longitudinal section through one margin of the trussed joint-plate, and a transverse section through one end of the block resting thereon which receives the base of the rails at their ends, the ends of the ties on each side of the joint and the transverse bolts passing through the web of the rails, appearing in section.

Referring to the characters of reference, 1 designates the truss plate for the rail joint, the central portion of which between the ties 2 is depressed, or curved downwardly, as shown, to form a support for the bearing block 3 which rests u on and extends transversely of the centra portion of said plate,

and is provided with terminal [langes 4 at its ends which embrace the margins of said plate to prevent transverse movement of the bearing block thereon. The end of the narrow or light rail 5 rests upon the upper face 6 of the block 3, while the end of the wide or heavy rail 7 rests upon a step S formed in the face of said block, as clearly shown in Fig. 4l, the end terminals of the face of the block and of said step, being provided with vertical flanges 9 and 10 respectivelyr which embrace the opposite edges of the base of said. rails toassist in maintaining the joined ends of the rails in perfect alinement. The vheight of the bearing block 3 above the surface of the step vS compensates for the difference in the cross section of the rails, and supports the end of the light rail 5 in a manner to maintain a perfect surface between the rail ends and effect a practical continuity of the rail through the joint.

T o provide for supporting the light rail at the point where it crosses the tie and near its end, the rail joint-plate at the end which rests upon said tie and receives the base el' the light rail, is made sufficiently thick, as shown at 11, to support the base ol' the rail in alineinent with the top 6 of the block 8. Bolted to the opposite sides of the rails at the oint by the `transverse bolts 12, are the angle bars 13 which extend onto and partially embrace the base of said rails. baid angle bars are notched at the center to `fit the step in the block 3, and at their ends are provided with the laterally extending flanges 14 having spike slots 15 therein which register with like slots in the margins of the end portions of the truss-plate, enabling the spikes 16 to be driven into the ties through said flanges of the angle bars and through the end portions of the truss-plate to anchor said parts to the ties, and at the same time iirmly join the terminals oi' the angle bars and the truss-plate.

Formed at the terminals of the truss-plate on each side of the rails are the lugs or shoulders 17 which engage the ends of the angle bars, whereby the tendency of the ends of the truss plate to draw together when the heavy weight is applied at the center thereof, is resisted by said ugs and the strain of the weight at the center ol' the truss-plate is applied to the opposite ends of the angle bars, thereby effecting a perfect truss for the support of the rails at the joint.

This arrangement provides a suspension joint in the form oi a truss which carries the load between the ties, and which, while affording a perfect surface between the rails at the joint, is suiiciently flexible to maintain the wave movement of the rail through said joint practically the same as along an unbroken rail, insuring stability as well as iiexibility at the oint, at the same time preventing a deflection in the end of the trailing rail and a consequent blow on the head oi' the facing rail by the passing wheels, resulting in a saving of labor in maintenance, a prolongation oi' the li'l'e of the rails and making a smoother riding track.

Having thus fully set forth my invention, what l claim as new and desire to secure by Letters Patent, iszl. ln a truss support for rail joints, the combination with the meeting ends oi the rails oi different transverse section, of the angle bars embracing said ends, a trussplate mounted upon the ties and supporting the rails and angle bars, said truss-plate having a depressed central portion and an end portion of increased thickness lying under the lighter of said rails, a block interposed between the depressed portion of the truss-plate and the joint of the rails supporting the ends oi' the latter', said block having two bearing surfaces in different planes to compensate for the difference in the height of the rails, and bolts passing through the angle bars and through the web of the rails to secure said parts together.

2. In a compensating truss support for rail joints, the combination with the rails of different transverse section, oi' the angle bars crossing the joint between the rail ends and bolted to the rails, a truss-plat-e having terminal portions lying under and supporting the rail sections and a depressed central portion, a block carried by said depressed central portion having bearing faces in different planes which receive and'supporttlie meeting ends of the rails, and means eiiecting an engagement between the terminals of said trusslate and the end portions of said angle ars.

3. ln a compensating truss support for rail oints, the combination with the ends of rails of dierent transverse section, of angle bars crossing the joint between said rails and bolted thereto, a 'truss-plate having terminals resting on the ties and supporting the base of the rail sections, one of said terminals being relatively thick to compensate for the diiiierence in the height of the rails, the central portion of the truss-plate being depressed between the ties, a bearing block carried by said depressed portion having supporting l'aces in different planes which receive the meeting ends of said rails, means for tying the angle bars and the truss-plate together at their margins, and means i'or imparting the longitudinal stress upon the trusslate to the ends ot' the angle bars.

4. in a truss support for rail joints, the combination with the rails of different transverse section, of a truss-plate lying under and supporting said rails near their ends, angle bars crossing the joint of the rails and bolted thereto, the central portion of the trussplate being depressed below the joint, and a bearing block carried by the depressed portion of said plate having supporting faces in different planes which receive the ends of said rails.

ln testimony whereof, l sign this speciiication in the presence of two witnesses.
