references or description thereof, that is to say :-
My said Invention, which consists in making axles (for carriages) which

and in otherwise reducing the friction by means of conical bearings on the outer
and inner ends of the arms, as described in the Drawings.
A, A, the axle, which is perfectly straight, having both arms and bearings
turned on the same centers. B, B, the box, which is chambered. C, C, the
conical bearing (on the outer end of the arm) which is prevented from turning
by means of a groove in the cone and feather on the arm, or by a steady pin
in the washer. D, the washer. E, the nut, which is sexangular, and cut
through for the reception of a forelock. F, cap, which, screwing over the box,
prevents the escape of oil. G, turned bearing of the axle. H, brass gudgeon
or bearing for receiving the axle, and attaching it to springs, bed or stay iron,
&c. I, I, part of a spring shewing the method of attaching the gudgeon and
axle. K, K, part of a bed for the same purpose. L, L, screw bolts and nuts.

The axle being attached to the carriage by means described, the wheel is
put on, the movable conical bearing C is then introduced, the washer D
placed over it, and screwed down by the nut E until there ceases to be any
shake, and the wheel turns freely; then put on the forclock and screw on the
cap. It is supplied with oil by means of a tube through the nave, or by
perforating the cone C, and making the cap act as a reservoir.
In witness whereof, I, the said Robinson Kittoc, have hereunto set my
hand and seal, this Thirteenth day of August, in the year of our
