page_text: my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that it has been
communicated to me from abroad by Charles Albert Hussey, of the
City, County, and State of New York, United States of America.
NOW KNOW YE, that I, the said Alexander Melville Clark, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Sheet of Drawings,
and to the letters and figures marked thereon (that is to say):
This Invention relates to a new and useful improvement in the
journal bearings of railroad carriage axles, shafting, or such like, and it
consists in so constructing the bearing that currents of water or other
liquid or fluid are made to pass through them and prevent them from
becoming heated by the friction of the journal. In also consists in the 1
combination of tubes with the bearing.
In the accompanying Drawing, Figure 1 is a longitudinal section of a
railroad carriage axle box taken on the line x, x, of Figure 2, showing the
bearing; Figure 2 is a cross section of the same taken on the line y, y,
of Figure 1, showing also a cross section of the bearing; Figure 3 is a 2
section of the bearing taken on the line %, %, of Figure 2. Similar
letters of reference indicate corresponding parts.
A represents the axle box of a truck which does not differ in form,
size, or construction from those used on ordinary railroads; B is the
axle; C is the journal; D is the journal bearing. The bearing occupies a
the same position on the axle and in the box that journal bearings usually
do, but its upper surface E is the are of a circle longitudinally, so that
it will more readily adjust itself to the axle.
The main feature of this Invention is the provision made for keeping
the bearing cool by means of a circulation of water or other liquid, or of
air through the bearing in any direction.
In this example of the Invention the conducting tubes F and G are
attached (by means of short stationary tubes H, H,) to the sides of the
bearing, and the bearing is made with four transverse grooves I, which

page_text: 2ndly. The combination of tubes H, H, and E, G, (or their equivalent)
with bearing D for the purposes described.
In witness whereof, I, the said Alexander Melville Clark, have
hereunto set my hand and seal, this Eighth day of October,
in the year of our Lord One thousand eight hundred and seventy- 5
