Improvements in Axle Piles and the like.
I, JOHN BAILEY BAUGH, residing at 193 Lafayette Avenue, Detroit, Wayne
County, Michigan, U.S.A., Master Iron-Worker, 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 :-
"
or
" axle
This invention relates to new and useful improvements in "box
piles," and consists in a certain construction and arrangement of parts, as hereinafter
fully set forth and pointed out particularly in the claims.
The object of the invention is. to produce a pile from which a superior quality
of axle can be made at a great reduction in cost thereof, over the bar piles in
common use, and in which the construction is such that there is little, if any, waste
in the furnace and a smooth exterior surface is formed for the axle which is free
from seams.
This object is attained by the formation of pile illustrated in the accompanying
drawing, in which ;-
Figure 1 is a perspective view of my improved pile the top of the case being
broken away showing the filling of scrap.
Fig. 2 is a like view showing the parts of the case in juxtaposition.
Fig. 3 is a transverse or diametrical section through the end of the case.
Fig. 4 is a longitudinal section through the same.
Referring to the letters of reference, A and B designate the side plates, and C
and D the top and bottom plates, respectively, which form the exterior case of the
pile. These plates are of rolled iron of the requisite thickness and length, and are
exact duplicates of one another, their longitudinal margins being bevelled or bent at
an obtuse angle to the plane of their face, as shown at a, so that when their edges
are placed together an oblong box or case is formed octagonal in cross-section, as
clearly shown in Fig. 3. This case so formed is then filled with properly selected
scrap-iron E, the ends of the case being first built up with scrap bar, as shown at b,
to more perfectly retain the scrap filling within the body of the case.
To prevent the sides of the box or case from spreading and retain it in proper
form, the cross-bars F are employed, which are forced into slots formed in the ends
of said sides and extend between and tie said sides together at each end of the case,
holding them firmly in place, which enables the box to be readily filled and prevents
it from falling down when moved or when placed in the furuace for heating. As
an additional security against the spreading of the sides and the collapsing of the
pile in the furnace when heated to a welding heat, a transverse strap-bar h is
employed at each end of the case which crosses the bottom of the case and conforms
to the angles thereof, its ends passing out through the joint between said bottom
and the sides and being turned upward at c, to embrace the bevelled faces of said
sides, thus securely fastening the bottom and sides together.
A great saving in the expense of making axles is effected in the use of a pile of
this character, as the only re-worked iron used is that which is employed in making
the case, the interior or core of the pile being the scrap filling, which if properly
selected, when embraced by the case giving a perfect outer surface, produces an
axle that will stand the test of a flat bar pile, but at a greatly reduced cost. The
drawing out of the axle as it is worked causes the fibre of the iron to extend
longitudinally producing a laminated core of great strength, which, supported by
the outer case, affords an axle of superior quality.
By reason of the particular shape of this case, the pile can be more readily
worked into the form of an axle, as it conforms to the concave of the hammer and

page_text: being devoid of sharp rectangular corners, is not squashed out of shape, and by
reason of the joints e between the bars of the case standing diametrically at an
acute angle to the rectilinear faces of said bars, a blow upon either face of said pile
tends to weld all of said joints, of which there are but four in the exterior case of
the pile and none of which have an exposed or lapping edge, so that there are no
seams to mar the surface of the axle which may be quickly worked into form..
When forming a box-pile for other purposes than the making of axles, the outer
casing may be rectangular in form, the plates thereof being flat and united by the
end cross-bars F, as shown, to retain them in shape.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is;
1. A pile consisting of a case formed of oblong iron plates placed together so as
to form a box, the side plates having slots in their ends, the end cross-pieces forced
into said slots to tie said sides together, and the filling of scrap iron in said case.
2. An axle-pile, comprising a case or box composed of oblong iron plates having
their longitudinal margins bent at an angle to the plane of their face, said bars
being placed edge to edge forming a case polygonal in cross-section, and the core or
filling of scrap iron embraced by said case.
3. In an axle-pile, the combination of the angle bars forming an enclosing case,
the cross-bars connecting the sides of said case, the angle strap-bar crossing the
bottom of the case and passing through the joint between said bottom and sides and
embracing the latter, and the scrap iron filling within said case.
