PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Car Axles and Shafting.
We, BENJAMIN FRANCIS PEACOCK, of Anniston, Calhoun County, Alabama,
and FRANCIS TOY PEACOCK, of Sparrows Point, Baltimore County, Maryland,
United States of America, Mechanical Engineers, do hereby declare the nature of
this invention to be as follows: -
Our invention relates to the manufacture of car axles. We may however employ
our improved method in the manufacture of any style of shafting, and for any
purpose for which our invention may be found suitable.
Heretofore in the construction and manufacture of car axles where extra tensile
strength has been an object, it has been customary, among other methods, to form
a pile or fagot, made from scrap-iron, muck-bars, or steel billets. Such piles, or
fagots, are then rolled or forged out in the usual manner.
To provide against the inherent weaknesses, frequently found to exist in piles
forged into car axles and the like in the usual way, we have devised the within
described improvements in the art, by means of which we are able to produce
shafting of a uniform strength, fibre and toughness, hitherto unknown in the art.
The axle or shaft is preferably composed of a diametrical section or pile which
extends radially clear across the shaft which has a rounded central portion or core
and a series of shorter sections which extend radially out from the central core to
the periphery. Each of the sections having concavo-convex interlocking contiguous
surfaces.
In a sectional pile produced in this way, it will be found that when the axle is
being turned up and finished there will be no sand or foreign matter in the seams
or journals, such as is frequently found to exist in the axles made from piles in the
usual way.
The strains upon this sectional pile, as we produce it, are so uniformly taken up
and distributed, owing to the peculiar relations of the parts, that it will be next to
impossible for it to give way other than by slight bending.

Improvements in the Manufacture of Car Axles and Shafting.
We, BENJAMIN FRANCIS PEACOCK, of Anniston, Calhoun County, Alabama,
and FRANCIS TOY PEACOCK, of Covington, Alleghany County, Virginia,
citizens of the United States, Mechanical Engineers, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention relates to the manufacture of car-axles. We may, however,
employ our improved pile for the manufacture of any style of shafting, and for any
purpose for which our invention may be found suitable.
Heretofore in the construction and manufacture of car-axles, where extra tensile
strength has been an object, it has been customary, among other methods, to form
a pile or fagot made from scrap-iron, muck-bars, or steel billets. Such piles or
fagots are then rolled or forged out in the usual manner.
To provide against the inherent weaknesses frequently found to exist in piles
forged into car-axles and the like in the usual way, we have devised the within

page_text: described improvement in the art, by means of which we are able to produce
shafting of a uniform strength, fibre, and toughness hitherto unknown in the art.
Figure 1 shews a transverse sectional view of a shaft made up of a series of
substantially radial longitudinal sections, which are preferably formed from the
best selected scrap or muck iron. These sections are forged or rolled in a machine
which we have devised and which we intend to apply for Letters Patent thereon.
Figure 2 is a transverse section of one form of section composing the axle, and
Figure 3 is a similar view of another form of section which we may use in the
manufacture of our invention. Both the section shewn in Figure 2 and the section
shewn in Figure 3 are used in the manufacture of a single axle or shaft.
In the drawings, A represents a section composed of a central circular part B
and diametrically opposite wings of the form shewn.
C represents the other form of the section, which is similar to A, except that the
cylindrical part B is absent and the sections C extend radially from the central
core to the outer edge or periphery of the pile.
D and E represent oppositely concave and convex formations, fashioned in the
sections A and C, which are adapted to interlock in the making up of the pile
preparatory to forging the same. We do not confine ourselves to the shapes of
these concavities or convexities, nor, as heretofore stated, to the precise shape or
conformation of the sections of which the axle is made up. In a sectional pile
produced in this way it will be found that when the axle is being turned up and
finished there will be no sand or foreign matter in the seams or journals, such as is
frequently found to exist in the axles made from piles in the usual way. The
strains upon this sectional pile, as we produce it, are so uniformly taken up and
distributed, owing to the peculiar relations of the parts, that it will be next to
impossible for it to give way other than by slight bending.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A sectional pile for shafting, provided with a diametrically arranged bar having
a central portion and radial wings, and a series of radial sections with interlocking
surfaces therefor.
