IMPROVED RAILROAD RAIL.

ro ALLWHOM rr MAY ooNonnN:

Be it known that I, ELNATHAN SAMPSON, of the town of Lansingburg, in the countyof Rensselaer, State of New York, have invented a new and improved Rail for Railroads; and I do hereby declare that the following is a full and exact description thereof. I

The nature of my invention consists of using two bars or rails in combination, and so placed that the ends of either rail will come to the centres of the others; and thusieach lapping the other half its length, alternate, forms acontinuous rail. One of these rails we call thc-supporting-or chair-rail. This rai may be made of ordinary iron, and when constructed of greater width on its bottom or base than ordinary rails, thechair now used can be dispensed with, and in Athis case the rail can be made from threelquarters to one inch lower than the rails now used. VThe-top of this chair-rail is about one-halt` inch wide, and its out-track side is perpendicular, with a Hang-e of suitable Width running out from it. Its in-track side is in form or outline, first, a slight angle, falling into a concave line, which runs outward, falling downwards toa point about two or two and onehalf inches from the perpendicular ofthe other sidc,and about ve-eighths of an inch from the lower line of 'the base, where it drops down slightly so as to form, with a rib which projects up, a groove about three-eighths of an inch deep. The projecting rib is about ve-sixteenths of an inch in width on its face, its side running down perpendicular about lhali'ran inch to the flange, which starts out from it. This chair-rail is secured to the-ties. 'lhe other rail we call the track or bearing-rail. AThis rail is made o'steelor a superior quality of iron, and of such height as to project slightly above the top of the chair-rail, and of width to aord V the necessary face for the wheel to run on. The outline of an end view of -this rail is on its top a iiatted curve, which'terminates at the point where it rests against the top of the in-track side of the chair-rail. From this point it runs down about half an inch,- slightly vout of the perpendicular, in a line corresponding with the angle of the chair-rail, and then in a shallow ogee line tothe groove of the chair-rail, in which it sits, then curving upwards into-a concave line, which falls into a convex line, ending in the atted curved line of the face, giving the rail an appearance not unlike a comma, with its head or dot latted. This bearingirail is placed in the chair-rail, its lower edge resting in the g'roove of the chair-rail, and the angular edge of the top or face leaning against the angle of the chandail, and the Whole face of the bearing rail contained Within a line running one-fourth ofan inch from and on a-perpendicular. with the bearing or lower edge of the rail, so that whatever weight is brought to bear on the rail its centre of grayity will always be in a line between the rib and the inside line. of the chairrail, and necessarily press the bearing rail against it.I The concave side of the chair-railwith the` ogee side of the bearing rail leaves, of necessity, a space between the two rails.A This space is for the passage of air, which can circulate, andV thus, .t0 a -degree, lower the temperature to which the rail may be heated in the summer months by solar action. l

In putting down these rails, the chair-rail is first laid down and properly secured to the ties by spikes or bolts, as rails are 110W secured. The bearing-rail is-then put down, or rather set in the chair-rail, as described, its lower edge resting in its groove, the inside-edge of the face resting against the top ofthe concave side of the chair-rail, and at the saine time the ends of the ono rail meeting at the centres of the other; and when, thus placed they are secured together by square or oval head-bolts passed through the bearing-rail tiret, then through the chair-rail, and tightened by nuts on the perpendicular -side, 'or by rivets, or their equivalents.

To en-able others skilled in the art to makeand use my invention, I will proceed to describe its construction and operation, reference being had to the accompanyingdrawings, and the letters of reference marked thereon, the same letters referring to like parts. l l l Figures 1 and 2 are perspective views of rails.

Figure is a top view shpwing joint-ings and fastenings.

Figures 4, 5, and 6 are a cross-section with wheels running straight and on curve.

A, iigs. l, 2, 3,-1, i3, is the chair-rail, made 0i' ordinary quality of iron, and ot' the usial length of other rails, and in height from three to four inches. The top of this rail, a, is about one-half in'ch wide, and made with a slight sloping curve, so that the wheel W, figs. 4, 5, and (i, will not touch it, and at the same time slide the dust and sand that may fall on it oil, though, if thought best, the top linea may be made straight or at right angles with the liuep, as shown in Figure 7, so that ifthe bcuring-rail be made of iron instead of steel, the wheels can be carried over the jointings of the ends of the bearing-rail without the jumping motion which usually attends the passing of the wheels over their ends where joined. The outside line l?, figs. 4, 5` and 6, falls perpendicular to the flztugef, which is inaile of suitable width and thickness. The inside line c is concave, and runs out to full in the groove g, which is partly formed ofthe rib r', from which there'starts another flange, f', of width and'thickness of llange f. This ruil A is firmly secured to the ties 'l by inc tns of thc spihosor bolts, s s. This rail A supports and holds another rnil,"B, culled the bearing-rail. This rail is metile of thehest quality of iron, or steel. The top, a, of this rail is made acurve slightly lertted, so that the wheels will have sufficient ben-ring surf-uc?. The inside edge, z', of the head of the rail is slightly'bevelled, to moet the bevel or angle of the top of tl e concave line c of the rail A, gs. 1, 2., 4, 5, 6. From the lower termination of this bevel line z', the lino turns under and down, 'forming the ogee shape line, which terminates at the bottoni edge of the rail at k. This bottom edge' k rests in the groove g. The outside line of this rail, B, commencing at the face line, is'irst convex and then concave, forming another ogee line, t, and terminates at the bottom edge Ic. The concavitjY of4 this line h permits the head of the bolt m to draw under edge of the head of the rail which Aprojects oifer, and protects the bolt from contact with the lange of thc wheel W when turning a curvo, as in iig. -5. The bottom edge lc, standing in the groove g, projects out beyond the outer edge of the head of the rail, as shown by the dotted lines n, fig. 4so, Whatever pressureis brought to bear on the rail B, its centre of gravity, being between the concave line e of the-rail A and the dotted line n, tends to press the rail B 'harder against the rail A; and whcther'running in :t straight line, as inlig. 4, or on the outer track, iig. 5, or on the inner track, iig. 6, the bevel oi' the wheel W being always the same, does not nli'ect or' change line of the centre of gravity. The chair-rail A being first laid and secured,.z1s has been described, the rail B, with its lower edge, 7c, in the groove g, and its edge, z',against the side of the top of A, is so placed that thcir'ends will. moet nt the centres of the rails A, iig. 3, nnd when so placed, the rails A and B are properly secured with the bolts m m or rivets; and when thus placed, we have the space or passage-way o running throughoutthe whole length of the rails. p

kThe advantages of this ruilfover others are these: first, we cnn dispense with chairs; second., the chair-rail A can be made ofcommon or ordinary iron', and yet be rendered safo by the rail B, which is of steel or of the best quality ofiron; third, a steel or a better quality of iron rails can be nlorded at one-halfthe price they are noir obtained, as the quantity of that material is 'less than one-half in this rail B than those ot' the various forms now used; fourth, the hearing-rail B can be taken out, when Worn, and replaced, in less thanv one-heli' the time now required to replace any other rail now in use; fifth, these rails, A and B combined, will support greater weight and resistgreuter strain than any other rail used, ns the bearing edge k reacts against the bevelled edge z', when pressure is brought upon it, and combined with the stili` support of the rail A will more eiectually resist the side strztin which attends the turning of curves by the train when passing over the rails; sixth, the space o admits the circulation o'l air through the rail, and tends to counteract the expansive action of thesun.

I do `not claim moltmg rails continuous, or fastening them with bolts, rivetsor their equivnlents.

I What I claim as my' invention, and desire to secure by Letters Patent, isv 1. The chair-rail A, constructed with its sides P C, top a, groove g, and rib r, together with the usual baise and tlzxnges, substantially 'as set forth and described.

2. The beariug-rail B, constructed with its 'track face e, bevelled inner edge z', sides h L, bearing edge'k, .s'ubstantiallj,Y as set forth an-d'described. ELNATHAN SAMPSON.
