Improvements in Car Trucks.
I, CHARLES WALLACE HUNT, of Barker Street, West New Brighton, in the
County of Richmond and State of New York, United States of America, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
The first feature of this invention relates to a cross bearer connected at its ends
to the side frames of the truck, the cross bearer being united to the car body by a
king bolt or similar connection, and the ends of the cross bearer and the side frames
are united in such a manner that the side frames can turn or swing vertically upon
the ends of the cross bearer, the object of this construction being to allow a limited
amount of movement or play of the side frames of the car truck, in order that such
truck frame may accomodate itself to inequalities in the track over which the truck
passes, the present improvement being especially available upon industrial railways,
such as used in quarries, mines, and manufacturing establishments.
The second feature of the improvement relates to the side frames of the truck of
metal with edge flanges for stiffening the metal in different directions, so that a car
truck frame can be made entirely of metal and sufficiently light; I prefer to employ
sheet steel or wrought iron stamped up with the edge flanges, or such side frames
may be of cast metal.
The bearings at the ends of the cross bearers for connecting the side frames to the
ends of the cross bearers, are made in the form of rings or divided rings secured to
the side frames by bolts or rivets, and with a cross bearer that is tubular I find it
advantageous to employ a tie bolt passing through the cross bearer and clamping
the parts by plates that come at the ends of the cross bearer and adjacent to the.
side frames. The side frames are provided with openings for the axle boxes to
slide in, or the axle boxes may be suspended by links from the side frames.

Improvements in Car Trucks.
1, CHARLES WALLACE HUNT, of Barker Street, West New Brighton, in the
County of Richmond and State of New York, United States of America, Manu-
facturer, 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 :—
The first feature of this invention relates to a cross bearer connected at its ends
to the side frames of the truck, the cross bearer being united to the car body by a
king bolt or similar connection, and the ends of the cross bearer and the side frames
are united in such a manner that the side frames can turn or swing vertically upon
the ends of the cross bearer, the object of this construction being to allow a limited
amount of movement or play of the side frames of the car truck, in order that such
truck frame may accommodate itself to inequalities in the track over which the

page_text: truck passes, the present improvement being especially available upon industrial
railways such as used in quarries, mines and manufacturing establishments.
The second feature of the improvement relates to the side frames of the truck of
metal with edge flanges for stiffening the metal in different directions, so that a car
truck frame can be made entirely of metal and sufficiently light; I prefer to employ
sheet steel or wrought iron stamped up with the edge flanges, or such side frames
may be of cast metal.
The bearings at the ends of the cross bearers for connecting the side frames to
the ends of the cross bearers are made in the form of rings or divided rings secured
to the side frames by bolts or rivets, and with a cross bearer that is tubular I find
it advantageous to employ a tie bolt passing through the cross bearer and clamping
the parts by plates that come at the ends of the cross bearer and adjacent to the
side frames. The side frames are provided with openings for the axle boxes to
slide in, or the axle boxes may be suspended by links from the side frames.
In the drawing,
Fig. 1 is a plan view of a truck with my improvement thereon.
Fig. 2 is an elevation of the same.
Fig. 3 is a sectional elevation of one frame and the axle box and supports at the
line z, z, Fig. 2.
Fig. 4 is a section at the line a, r, Fig. 2.
Fig. 5 is an elevation of the inner side of one truck frame in a modified form and
a cross section of the central bearer.
Fig. 6 is a section at the line ³, a¹ of Fig. 5.
Fig. 7 is a similar section representing the connection between the cross bearer
and the side frame in a modified form.
Fig. 8 is a sectional plan view of one axle box and of the frame at the line y, y,
Fig. 5.
Fig. 9 shows the inner face of one of the side frames, and
Fig. 10 shows the cross bearer with the frame in section, and
Figs. 11 and 12 are sections of modified bearings for the ends of the cross bearer.
The axle boxes A. and axles B are of any desired character, and the wheels may
be either inside or outside the axle boxes. The side frames C may be provided
with openings. for the reception of the axle boxes A, as seen in. Figs. 5 and 9, and
where there are springs D they may rest upon brackets 4 extending out from the
axle boxes A and the upper ends of the springs may rest against the under side of
the top flange 2, or special flanges upon the side frames C may be provided for the
upper ends of such springs D, and the tie plates E' are provided across the
openings into which the axle boxes A are received as usual; but my present
improvements are equally available with the side frames C₁ with suspending
links P for the cross heads Q over the axle boxes A¹ and springs D', as shown in
Figs. 1 and 2.
In consequence of side frames C. or C¹ of the truck being of metal and having
flanges, they are very stiff and at the same time comparatively light, and these side
frames may be of malleable.iron or of wrought iron or steel, either cast or struck
up in dies.
In the middle of the side frames there are cylindrical sockets for the reception of
the round ends of the transom or cross bearer F. This transom may be of any
desired form for securing the required strength and it is provided with a central
bearing 6 at the king bolt, and there are shoulders at 7 that rest against the inuer
ends of the sockets upon the side frame C, and the parts are firmly secured
together, preferably by the tie bolt G that passes longitudinally through the
transom and through the cap plates H .against the outer surfaces of the side
frames C or C',' so that by means of the tie.bolt and these plates, the side frames C
will be reliably secured upon and connected with the transom F and at the same.
time a slight turning motion of the side frames upon the tubular ends of the transom
is allowed for, in order that the respective ends of the side frames,may rise or fall
in relation to the opposite side frame, thereby allowing for a movement or working

page_text: of the one frame in relation the other as the was pass yu
track.
In Fig. 7, I have represented a collar I as riveted upon the surface of the side
frame and surrounding the outer end of the transom, so as to give additional
strength to the connection between the transom and the side frame, and in this
form the cap plate H rests against the collar I instead of against the surface of the
side frame C.
It will be understood that this construction of truck frame is adapted to coal
cars, freight cars, platforms, etc.
In Figs. 1 and 2, I have shown the yokes E as extending from one axle box
to the other, and the hinged frames L as connected at M to the sides of the
transom F.
The metal at the central bearings in the side frames may be conical, as seen in
Figs. 10 and 11, or cylindrical, as seen in Fig. 12, for the reception of the ends of
the cross bearer, and reinforcing flanges or rings 26 and 27, Fig. 10, can be used to
set around the ends 18 of the transom or cross bearer F, and these rings or
flanges 26 and 27 are bolted or riveted to place and they serve to strengthen the
side frames at the bearings and to allow the side frames to vibrate in vertical
planes as the wheels of the truck pass over inequalities in the rails, there being
a slight turning motion of the side frames upon the round ends 18 of the cross
bearer.
If desired, the outer ring or flange 16 may be stamped up or cast with the side
frame or be a separate piece, as represented in Fig. 11, so as to enclose the end of
the cross bearer F and protect the same from dust, the ring 17 being removable
and made in two halves if necessary. In this case the round end 18 of the cross
bearer F may be either cylindrical or convex. In some instances the cylindrical
end 18 of the cross bearer F, Fig. 12, may have a collar at the outer end and the
flanges or rings 36 and 37 may be divided into two parts, so as to be set around
the end 18 of the transom F and within the shoulders thereof, or the rings or
flanges 36 and 37 may be complete and the collar 10 may be formed by a movable
piece fastened on at the end of the round bearing 18 of the cross bearer F, as
shown by dotted lines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
First. The combination in a car truck frame of side frames having central
bearings with a metallic cross bearer having round ends and received into central
bearings in the side frames, substantially as set forth.
Secoud. The side frames for a car truck, formed of metal plates with turned up
edges or flanges, and central bearings in each plate, a metallic cross bearer or
transom having cylindrical ends and passing into the central bearings of the side
frames and secured therein, substantially as set forth.
Third. The combination with the metallic central bearer or transom having
round ends, of side frames having openings for the axle boxes, and round openings,
and rings or flanges secured within the openings for connecting the side frames and
the transom, substantially as set forth.
Fourth. The combination in a car truck, of side frames having openings for the
axle boxes and central openings with a metallic cross bearer having round ends,
ring flanges secured to the side frames and receiving the round ends of the transom,
substantially as set forth.
Fifth. The combination in a car truck, of a transom having round ends, side
frames of metal plates with flanges on the edges and central openings for the ends
of the transom, and ring flanges surrounding the ends of the transom and connected
to the side frames for firmly uniting the respective parts and for allowing the side
frames to rock vertically on the ends of the transom, substantially as set forth.
Sixth. In a truck for cars, the side frames of metal having stiffening flanges and

page_text: tubular sockets, in combination with a transom or cross bearer having round ends
passing into the cylindrical sockets of the side frames, a cross bolt passing through
the tubular transom and cap plates and nuts at the ends of the transom and outside
the side frames, substantially as set forth.
Dated this 11th day of December 1893.
