COMPLETE SPECIFICATION filed by the said George Edward Vaughan at
the Office of the Commissioners of Patents on the 6th October 1881.
GEORGE EDWARD VAUGHAN, of 67, Chancery Lane, in the County of Middlesex,
Patent Agent.
"IMPROVEMENTS IN AXLE BOXES." A communication from abroad
by Henri Cristin, of Paris, in the Republic of France.
This Invention relates to improvements in the construction of axle boxes
applicable to vehicles and revolving machinery of all descriptions.
In the accompanying Drawings, which represent an application of the Invention
to an ordinary carriage, a is the stationary axle; b, the axle box provided with
two lugs c, c, by which it is keyed into the nave of the wheel; & represents one
of a series of cylinders, the diameter of which varies according to circumstances,
and which are terminated by pivots o, and so arranged as to prevent their contact
with each other. The extremities of these pivots o pass freely into the rectangular
notches of the metallic rings f. f. The pivots being inserted in these notches, the
rings f, f¹, are connected by means of the rods e secured in the outside by double
nuts. The cut away portion of the ends of the cylinders should be of greater
width than that of the cavities formed in the rings f,, so as to prevent them
froin passing into the latter in case of accident. The inner opening of the
rings ff, is of larger diameter than that of the axle a, and the spacing is so
arranged as to prevent friction between theso rings and the inner surfaces of the
box. The dimensions of the rectangular notches or cavities are so arranged as to
give free play to the pivots, while preventing contact between the cylinders;
9, g, represent thick leather washers designed to check the jerks and lateral
oscillations to which ordinary vehicles are exposed. These washers g, g, are
preferably composed of two layers of leather so combined as to form rectangular

carried almost without friction round the axle a. In case of accidental jerk, the
ends of the pivots o are brought momentarily into contact with the projecting
portions and are thereby thrown back to their normal position. At all other
times the washers g, g, are carried freely round by the nuts. The inner or notched
portion of these washers may be covered over by a flat ring of steel secured in any
suitable manner. The number and dimensions of the cylinders or rollers d, as also
the general construction and arrangement of the apparatus, are varied according to
the purposes to which the Invention is to be applied.
Having now described the nature of the said Invention, and the manner in
which the same is or may be carried into effect, I declaro that what I claim and
desire to protect by Letters Patent is,-
The application to axlo boxes of a series of rollers or cylinders as in d, with
terminal pivots as in o, in combination with notched metallic rings f, f, connected
by tie rods e, the whole constructed, arranged, and operated substantially as herein
set forth and shewn in the Figures of the accompanying Drawings.
In witness whereof, I, the said George Edward Vaughan, have hereunto
set my hand and seal, this Fifth day of October, in the year of our Lord
One thousand eight hundred and eighty-one.
