'IO LL WHOM I'l MAY CQNCERN:
Beit known that I` 'lnoMAs E. Pnnennsn, ofthe city of Reading, :md Stute of Pennsylvania, have inventedy a new und useful Improvement in the Manufacture of Railroad-Rails; and I do hereby declare the following to be u fuit und exuct description nl' the sume. reference being had to the annexed drawings, in which- Figure l represents n vertical section oi' n. rail constructed on the plan of my improvement.
Figure 2, u perspective view of the pile formed on my improved pion. I
Figure 3, the same shownin section. I
Figure 4, n perspective view of the pile formed in the ordinury'method.
Figure 5, n v-ertienl section of :i ruil made from the ordinary pile.
Figure 6 represents the two upper layers shown in fig. 2. in increased size, showing nccurntely the proportions of the parts.
llcreto'fore it hos been customary to make the pile for rails of a number of dat burs, placed in series of pnrullol layers, ns shown in iig. 4..V It will be seen, on reference to this ligure, that the common pile is mudo up of nine layers oi' bars, theI q-uulity ofthe iron'of which is variodto suit its position in the pile. Thus, tho
bnrs A B C, which form the linge of the ruil, are of reworked or `granular iron. The bar D sind other middle bars, 'which forth the stem of' the ruil, are of an inferior quslity of iron. The vtop bar, R, which lcovers the' khoud of the ruil, und is moet liable to weer and tear, is also'of the granular iron.
Eschof' the middle layers is made up of two separate bars, but in my pile these middle layers ure single bars, whioh I have found to increase the strength of the rail. Y Y
Preparatory to .the operation of rolling the pile, it is introduced into a heating-furnace by means of u piel. In withdrawing the piel, the layers -of the pile being loose, ure liable to-be displaced. The displacement is of frequent ooourrence,` and con be but imperfe'ctly remedied by the operator, who knocks or presses the displaced layers-into something noar their proper position. A slight displacement of this Akind inthe top layer of the pile produces -a most injurious effect on the wearing quality of. the ruil, since, by making seid bur oblique to the body of the pile,- it is spread unequnlly and imperfectly over the hsdvof the ruil in the opration of rolling.' Thus, ut some points'it will form the side or stem of the rail, and the inferior iron of the middle bars of the -pile willfbo rolled into the Aheud of the rail, rendering it more liable to disintegration und lamination. My improvement consists in forming the top layer of the pile, which is to be 'of sufficient size to form the' head of the rail,` litho." 'irregular welding-surface, and also in providingtholsyer in contact with the top or cap-piece with an irregular surfuceconforming to and matching or fitting into 'said irregular welding-surface in the top or cap-piece. The size o r shnpc of the irregulanwolding-surface on either piece is immaterial, kthe object of my invention being to prevent u displacement of the layers in charging the pile into the heatingfurnnce. V, l A
The pils' above' .deaoribed is-for u sixty-five pound rail. The itdvantages of my mode of piling nre, that I can produceA- 1 nil oiil'les's average liability to laminate, nndgreat'er average durablility, than can b'e produced by the ordinziry modes of' piling.
What claim, and desire to secure by-Letters Patent, is'- l -1'. The msnufso'tnro-of 'railrosdq'ails from s pile, the topA bar o iwhich is of s superior quality of iron, immovableA later-olly, und` suoentlyhs'avy toggivo the rail when rolled s consolidated head,ponnecting with the loro-:Joyas in the stemof thoruil, substantially as above set forth.
2. I also claim ,an intormediste iron lform-picosfor avfsgot for a ruilrosdrsil, such form-piece .boing-oonl|truotsd-witl'n, sn .irregular welding-surface, for fitting is corresponding welding-surface in the superior metsl esp or top-pisos, substantially u described.
