page_text: Figure 1-Is a longitudinally section of one half or section of my improved
truss, the section of the axle being shown in elevation, in position therein, the
wheel being shown in diametric section in position on the axle.
Figure 2 Shows in elevation, the respective parts which are shown in figure 1;
but representing the other half of the truss and axle with wheel in position on the
axle.
Figure 3-Is an elevation representing the abutting ends of the sections of the
truss and axle, as viewed from the left in figure 1, and from the right in figure 2.
Figure 4-Is a transverse section taken as on line Z, Z, and represents the axle,
the truss, and the anti-friction metal in which the axle is journaled.
Figure 5-Is a view similar to figure 3, but showing various modifications in the
configurations of the cross section of the stay rods of my improved truss.

page_text: In said drawings, A, A, represent the wheels, which may be of any size form or
kind, adapted to use as a car wheel. The two sections or halves of the axle are
represented at B, B; and the two halves or sections of my improved truss are
shown at C, C; each of said sections C, being a unitary metallic casting, and
embodying a disk b, at the inner or abutting ends; a disk or hub e, at the outer
ends; with rods f, extending from b, to e, and uniting the same, as parts of the
same casting, as above stated. The outer end of hub e, I enlarge as at g, to form
an annular recess to receive the inner end of the hub of wheel A, and I insert in a
corresponding groove, a packing ring h, of leather or other suitable material; and
I also form in said hub, concentric interior recesses to receive the anti-friction
metal i, poured therein in a fusible state; a series of inwardly projecting teeth v,
serving to hold metal i, from rotation, when subjected to the frictional action
resulting from the rotation of axle B. And between said bands of inserted metal i,
an annular oil chamber is arranged to receive the oil retaining packing j, as shown;
and at the inner end of said hub, I form a chamber or recess to receive the packing
ring p, of leather or other suitable material, and the concentric flange of a set
collar n.
At the inner end of each half of the truss, I form a hub k, one end of
which is supported by flange b, and the other end by the radial studs 7, which
connect the hub with the longitudinal rods f. In said hub k, I form the chambers
for anti-friction metal i, the central chamber for oil packing j, and an end recess
for the packing ring p, and flange of set collar n, all as shown and described, with
reference to the outer hub e. And I arrange an opening in each hub to commu-
nicate with oil packing ), the same being covered with a cap as shown at m.
Disks b, are respectively formed upon their meeting faces with an annular recess c,
and corresponding projection d, which when interlocked, and secured by bolts
inserted in holes w, serve to hold the sections of the truss in perfect axial coin-
cidence; and to prevent lineal displacement of the sections of the axle, I form near
the inner or meeting end of each half of the axle, a concentric groove t, in which
an angle or concentric lip of the sectional collar s, is seated, (figure 1, 3,); said
sections being secured in position upon the axle by band u, as shown. A journal a,
of the axle extends outward from the wheels in the usual manner, to receive the
box in the truck frame.
In figure 5, various modifications of the outline of the cross sections of arms f,
are represented; 2, being a cross; 3, tubular; 4, T shaped; 5, H shaped ;
6, Ushaped; 7, T shaped but arranged the reverse of 4; and 8, represents a
corrugated web which may be employed to unite disk b, and hub e.
I am aware that it is both old and common to transversely subdivide car axles
at the center, and to journal the sections, thus subdivided, in tubes formed with
flanges at their abutting or inner ends; hence I do not claim such construction
broadly or in the abstract, my invention consisting in a truss, each half of which is
formed as a unitary casting, with flanges at the abutting ends, and a hub or flange
at the outer ends; with rods or stays, uniting the two, and arranged oblique to the
axis and diverging from the end hubs to the middle or abutting flanges.
Hence, I claim as my invention―
1st A car axle truss, formed in two sections C, C, each being a unitary casting
and having an abutting flange b, adapted to be bolted together, and a smaller flange
or hub e, with rods or stays f, uniting the two and arranged obliquely to the axis ;
substantially as specified.
2nd The section B, of the axle, formed with groove t, the sectional flanged ring 8,
and the enclosing ring 2, and a recess in flanges b, to receive said rings; substan-
tially as specified.
3rd In an axle truss, formed with flanges b, rods f, and hub k, the radial stays l,
uniting said bub and rods f; substantially as specified.
4th In an axle truss, and in combination with hubs e, k, chambered as shown,
the flanged collars n, and ring packing p; substantially as specified.

page_text: 5th In a car axle truss, the outer hub e, formed with a chambered enlargement g,
to receive the hub of wheel B, and a ring packing h, arranged in said chamber,
substantially as specified.
6th In an axle truss, the hubs e, k, formed to receive axle B, and with an annular
recess to receive the oil packing j, with a radial opening to afford access thereto;
substantially as specified.
7th The hubs e, k, formed with annular recesses toothed as shown, and adapted
to receive the anti-friction metal 1, therein to serve as the journal bearings of
axle B, substantially as specified.
8th The sections C, C, of an axle truss, formed with abutting flanges b, respec-
tively formed with concentric recess c, and projection d, fitting therein; substantially
as specified.
