IMPROVED BATLROADRAIL.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CLARK OSGOOD, of Cape Elizabeth, in'thc county of Cumberland, and State of Maine, have invented a. new and improved Continuous Rail; and I hereby declare the followin-gto be a full, clear,

and exact description thereof, which will' enable others to make and use my invention, reference being had to i the accompanying drawings, forming part of this specification, in which- Figure 1 shows a side elevation of a portion of a rail constructed inmy improved'manner.

Figure-2 is a vertical transverse section ofthe same.

My invention has two principal objects in view, rst, to lay the rails in suchluanner that the ends thereof, being so connected as not to springup, are not liable to be cracked and broken by the wheels of cars; second, to make the rail continuous .or unbroken, by so connecting thc several bars that cach shall assist in keeping in position its contiguous bars, and still all the-bars be susceptible of a ready removal for purposes of repair, Src.

My invention consists, rst, of a series of cap-rails united toeach' other by pintles in their ends, together with the support or bed, the two parts beingjoined as hereinafter described.

A shows the support or bed for the cap-rail, b representing the base, .intended to rest upon the sleeper or other foundation on the road, and 'secured as is commen. Theftop of the support A, or thc part where itreceives thecap-rail, is shapedas follows: First, as indicatedby the'lines l'1,vthat'is to say, bevelledor inclined toward the outer edges thereof; furthermore, from the point where these :inclinations or bcvels begin, o, .V or U-shaped recess is constructed, which is indicated in the drawings by the lines 2. A corresponding formation is given to the cap-rail, which rail in the drawing is designated by'C; that is to say, itiis'so inclined or chan. nelled as to overlap that part of the support indicated by the lines 1, and has a Vlor U-shaped projection, to 'll the corresponding groove or depression indicateflby the lines 2. represents the pintle, which enters the two ends of the rails, as shown in fig. 1.

It is obvious that bythe peculiar formation of 'the bottom of the cap-rail and the top ofthe bed, the cap.-

rail is held in position on the bed, and a series ot' rails united by the pintlesd and placed in their position on the support A will be securely retained in such position, little liable to warp 01' spring, and their ends, where the rails adjoin each other, must necessarily be kept even, so that'ono will not be higher or lowerA that the other, and thus subject the raised end to wearing and breaking by the wheels of the cars. A slight space mnybo left between the ends of the adjoining rails, to allow for the natural expansion, and iu'this space, and around the pintle, there may be, if desired, a pieceof elastic substance inserted. l

When repairs are to be made, and a length of the caprail is to be removed, it is onlynecessary to raise from their bed A the united rails for a sudcient distance and to the necessary height to-createa space between two rails wideenough to allow the pintlc to slip out, and then the rail can be removed and another. one put in its place inthe same way. v Thus the process of repairing is considerably simplified, there being no necessity of withdrawing bolts, &c. The cap-rai1 may be made of steel, but T do not claim constructing it of steel.

I am aware of Letters Patent, No. 44,562, granted to George D. Teller, October 4, 1864., and I do notI claim a double rail united by bolts, and having a-groove at Athe top, intou'hieh is inserted a bar or rail of steel. I am also aware of Letters Patent granted to Elnathan Sampson, March 5, 1867, and to J. S. Butterield and M. S. Green, May 22, 1866, and I hereby disclaim a groovcd chair-rail, constructed with a rib and bevelled inner edge, as well as a rail having a longitudinal v-groove on the upper portionand a longitudinal rib on the lower, the two parts secured togetherby pins, as is seenin the patents of thesad Sampson, and Butterfield and Green, respectively; but i Y What Ido claim, and desire to secure by Letters Patent, is

The rail, composed of the support A and caprailvC, when the twolparts arc placed together as shown by 1,2, and when the several cap-rails are also united by'uthe horizontal pintle d, substantially as and for the purf poses described. v CLARK OSGOODL Witnesses:
