Improvements in Car Journal Boxes.
I, SYDNEY PITT of Sutton in the County of Surrey, Gentleman, (a communication
to me from abroad by Edward William McKenzie Hughes of Chicago, Cook County,
State of Illinois, United States of America, Engineer) 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:-
This invention relates to improvements in journal boxes for cars, made of pressed
steel and with but a single joint or weld. Heretofore journal boxes have generally
been made of cast metal, or when made of steel have required several weldings. The
journal box the subject of this application is made of a single piece of metal, pressed
and shaped as will be hereafter described.
The invention will be readily understood from the accompanying drawings, in
which:-
Figure 1, represents a cross-section through the metal plate to be shaped ;
Figure 2, an elevation of the box shaped by the first process;
Figure 3, a perspective view of the box when completely bent and welded ;
Figure 4, a perspective view of the strengthening crown-piece;
Figure 5, a cross-section through the completed box, showing the crown-piece in
position; and
Figure 6 a general view of the blank from which the box is pressed.
In forming the box I take a sheet of steel having approximately the cross-section
as shown in Figure 1, which may be cut by a die, or otherwise to the general shape
shown in Figure 6. The section shown in Figure 1 may be rolled continuously, and
afterwards cut off to the proper lengths if desired. The sheet shown in Figure 6 is
then bent hot, preferably by the Fox process of pressing steel, as, for instance, that
patented in America to Samson Fox on the 5th day of February, 1889, No. 397,179,
into the shape shown in Figure 2,-the offset K forming the part K shown in
Figure 2. The upper edges of the box are then pressed over a former and butt-
welded, as shown in Figure 3. It is preferred to do this welding by electricity. It
preferred to strengthen the upper part of the box by the crown-piece E having
ears F F, which may be welded in, or riveted as desired. The box is finished by

strengthen the box, and the interior flanges B B' serve as a slide to the wooden shield.
The completed box is evidently much lighter, simpler and more enduring than those
now made.
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 :-
1. A journal box for cars formed of a single piece of steel and having but one
joint, substantially as described.
2. The pressed steel journal box formed of one piece of steel and having flanges B B¹
CD and projection K formed of one piece of steel with but a single joint substantially
as described.
3. A journal box for cars formed of a continuous piece of pressed steel, and having
flanges surrounding the same pressed from part of the metal of the box, substantially
as described.
