- .IMPROVED RAILROAD-RAIL JOINT.-

TO ALL' WHOMT MAY CONCEEBN:

l Be it known that VI, BENJAMIN SCOTT, oi' New Brighton, in the county of Beaver, and Stute OfPennSylvnnin, have invented a new and nsoul improvement in Clamp Truss-Joint for Railroad Rails; and l do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, which are made part of this specification, and in whicht Figure l is atransverse vertical section cf rail, clamps, and'block. v

Figure 2 is a side elevation of the same. i' i Figure 3 is a side viewl of combination block.`

Figure l i's 4a plan `view of clamp, showing the groove and tangs in the angle.

Tbisvinvention consists of two sections'of a clamp, Vso.construci',ed as to form a truss-joint, to operate betweenA the cross-ties, for joining and supporting the ends of railroad rails. The said clamp is so made and applied as to embrace the base, webs, and necks of 4the rails, with angesbevelled from below upward, and projecting downward to any desirable length, meet at their lower-edges to form a fulicruin or bearing-point forthe screw-bolts, two or more passing through the said ilanges above their point of contact, and acting on the principle of the lever, to press rmlythe ends of the jaws of the clamp against the nccls of the rails, thus constituting, inl effect, a truss-joint of great strength and durability. l V

The invention further consists in combining, with the aforesaid clni'np, a block of hard wood, which' adds strength to thejoin-L, and brings the nuts into convenient position to be reached by a wrench from above, and prevents their working loose by the jarring of `the rails; llhereare also tangs.` in the angles of the grooves,

which engagein notches in the base of the rails to keep the clamp permanently in place, and, at-the saine time,

permit sufficient play to allow room for expansionand--contractien A A represent railroad rails of ordinary construction.vv B B represent `the two sections 'of'a wrought or l rolled iron clamp, oi' any length orwidth desirable, each section ofthe clamp consisting of a body, a, andjaw, b, made to fit closely the `base and web of the rails,.with the end of thejaw pressing against the neck of the rails, and a ange, c, projecting beneath the rails to anylength necessary to give the required leverage power.` f D represents the `fulcrnm point, and d d the bevel oi' anges from the fulcrum to the base ofthe rails,ani l z' the space formed by the bevels d il E represents the combination block.- H represents side view ofjoint, showingl the.bolts` g g, G represents a'plan view of a section of the clamp, showin-g the tangs h z, malle to engage in the sionof themas. j Y l My truss-joint is not intended .to rest upon the ties, but occupies a position between the ties, being supported only by the rails.`V The-joint is thus made very elastic, andthe ends of the rails nre less subject to wear and battering than when rigidly supported. The sectionsB B of the clarnp are so constructed that they williit closely `aroundthe-base and neck of the rail, and whenthey are adjusted to the rails,rand the lower edges of the flanges vare brought in contact, they `form a fulcrum, D, so that wren the bolts g are appliedv through the iangesiV above the-point of contact, they act as a lever, having the space 'i for its sweep, and make the bodies and jawsI I of the clamp, together with the flanges, operate as braces of strength suicent to secure rmly the ends of the 4rails in place, and the whole, in combination with the rails, form n truss between the cross-ties.

I am aware that railroad chairs have been constructed, in two parts, in such a waythat the downwardAV pressure ofthe rail upon the inner edges ofthe base of the chair, iisin the connecting-bolts as a fulcrum, will cause the jaws to gripe the neck'of the rail, as shown in D. W. Crocker-"s patent `of January 25, 1859; also,

i that it has been proposed to make railroad chairs with a. flexible connection iat-bottom, and screw-bolts above to clampthe jaws upon the rail. These inventions, therefore, I do not claini.

What I claim as my invention, and desire to secure by Letters Patent, is-g 4 1. The combination of the two rigid parts, B B, of a divided clamp-joint, Vconstructed witbjaws b b fitting closely around the base and neck oi the rails, and downwardly-projecting anges a a, meeting at their lower edges D, and -bevelled upward to form a space, t', between them, when usedh'in connection with bolts g -passed through the flanges a a 'above-the fuloruIn-point D,all as herein shown and described, and lor the purposes 4specified. A p I.

2. I further claim, in combination with the above, the blockoi' hard wood E, ttmgthe 4angle between the t ange and body of the olanspto facilitate the working of the nuts from above, and to obviate the jar, and thereby i by s t. x prevent t4 e un crewmgof the nu s BENJAMIN SCOTT. Witnesses:
