IMPROVEMENT IN RAILRoAn-AxLE.

The ,Schedule referred to in these Letters Patent and making p rt O the a- To all whom it may concern: V

Be it known that I, Gnonen H. H AGLAM), of Port Jervis, in the county of Orange, andState of New York, have invented anew and useful Improvement in Railroad-Axles, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawing, forming part of this specification, and in whioh- Figure 1 represents a longitudinal view of the'end portion of a railroad-axle, col'lstructed in accordance with my improvement, and

Figure 2 a longitudinal section of the same, with the turing anew axle, or of repairing an old or worn one, in

drawing out or otherwise reducing the ends of the axle, made, as usual, of wrought-iron, and then bringing said ends to a welding or other suitable heat, and casting on or over each of them a steel coat or outer covering,

by running the molten metal into a mould, surr0unding the end of the axle, to an extent and of a size. and shape necessary to form the journal, the steel becoming, by a state of'fusion, incorporated with or welded into or on to the drawn or reduced heated end of the wroughtiron axle, after which the axle and journal are hammered into proper shape, and thejournal finished as required; and by extending thesteel coat thus applied to either end of a wrought-iron axle, beyond the journal, and so as to embrace a portion of the body of the axle, and to enter or be received within, say, one-half the hubof the wheel, thereby giving ample protection to that portion of the axle most liable to break.

Referring to the accompanying drawing, A represents a wrought-iron railroad-axle, in part, with its e1 (t drawn or reduced, as shown infig. 2. The old or m axle, thus formed, at its opposite ends, has such portio afterwards brought to a red or other suitable heat, sa successively, as it is preferable to cast the steel 00 first on the one end of the axle and then on the 0th byplacing the axle in a verticalposition, and runni] the molten steel in from above, reversing the ends the axle uppermost for the pin-pose. The steel is r1 into a mould, surrounding the heated end of the axl to giver proper size and shape to the coat, which th becomes incorporatedwith the wrought-iron portio and the whole is atterwards hammered to give prop solidity and shape to axle and journal, and finished As represented in the drawing, it is preferred make the drawn or reduced end a longer than t] journal I), so that the cast-steel coat B-may be e. tended to enter wholly or in part the hub O of t] wheel, say, for half its width, 'or thereabouts.

A wrought-iron axle, thus provided with steel jou nals, will of course-be much more durable than witho the steel wearing-surface, without proportionably ad ing to the cost of its construction.

I do not claim, broadly, uniting steel with iron, I casting the former on to the latter whilst at a weldin heat, and subsequently rolling or swaging the ma into form; nor do I claim a wrought-iron axle, with steel facing, produced in like manner, or by conversh of the exterior in a cementation-fiunace, when so steel facing extends the entire length of the axle shaft; but v What I'do claim as new, and desire to secure '1 Letters Patent, i's

A wrought-ir0n axle, constructed with steel journz casings, extending about midway into the eye oft] wheel, substantially as and for the purposes specific GEOR. H. HOAGLAND.
