COMPLETE SPECIFICATION.
Improvements in Journal-boxes.
I, GEORGE FUSSELL, Jr., of Lockport, in the County of Niagara, and State of
New York, one of the 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 improvement relates more particularly to the main bearings of steam
engines, but it may be found useful in other engines or machines, and the invention
consists in the peculiar construction, arrangement and combinations of parts herein-
after more particularly described and then definitely claimed.
In the accompanying drawings:
Figure 1 is an elevation of one end of an engine frame provided with my
improvement partly in section.
Figure 2 is a vertical central longitudinal section of the same.
Figure 3 is an end view with parts removed.
Figure 4 is a perspective view of a section of the box removed.
Figure 5 is a perspective of a movable pillar whose object will be more fully
described hereafter.
Referring now to the details of construction-A represents the frame of the
engine having an opening a to contain the box, and to which the cap B is secured.
At C (see Fig. 5) is shown a pillar provided with a lug e which fits snugly in a
hole a bored into the back of the opening a. On this pillar is set one half of the
box D which is provided with a grooved rib d on the back to fit on the half round
surface of the pillar C. The other half of the box is of similar form and sets on a
pillar similar to that shown at C, which pillar is attached in a similar manner to the
cap B as shown at Fig. 2, and then the cap is securely bolted on as shown at E in
Fig. 1, thus holding the engine shaft F in a box that is perfectly self-adjusting as
to position.
By this construction, a bearing for a steam engine shaft is made that will enable
said shaft to run easy, even if the pillow block that carries its other end, gets
considerably out of line, either vertically or horizontally, and thus heating and
excessive wear of the journal and box will be prevented, for it is evident from
the construction described and shown that the box and pillars practically form
a self-adjusting bearing that will accommodate itself to any change of position
of the shaft.
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. The combination of a box D, having ribs on its back, of a holder for said box
engaging with said ribs, and constructed to move on a pivotal point in its support
substantially as described.
2. The combination with a divided box D, each section having a groove on its

page_text: outer surface, of the pillars C, fitted to said grooves and supported on central
pivots, substantially as described.
3. The combination with the frame of an engine, of a divided box D, each
section having a grooved rib, and a pillar C fitted to said groove, and provided
with a pivotal lug e fitting into holes in the frame of the engine, substantially as
described.
