I JOHN ADAM BERG of Peter Street Ashburton in the Province of Canterbury
New Zealand, Coach-builder do hereby declare the nature of this invention to be as
follows:-
An arrangement of grooved or flanged metal felloo or sweep pieces clasping and
carrying the wheel plate, which, while allowing a froe circular movement of the
wheel plate, will take the strain should the King bolt be broken or lost, and
proserve the attachment of the carriage body with the under carriage.
The grooved folloe or sweep pieces are proposed to be supported on iron stays
from the head block but may also be attached to or carried by the carriage bed
O by other means.

page_text: I JOHN ADAM BERG of Peter Street Ashburton in the Province of Canterbury
New Zealand Coach-builder do hereby declare the nature of my invention for AN
IMPROVED UNDER OARRIAGE FOR VEHICLES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The special improvement or device consists in the arrangement and construction
of two grooved or flanged felloe- or sweep-pieces supporting the wheel-plate and
clasping it so as to allow of easy and free motion but at the same time in such
a manner as to be capable of taking all the strain in the event of the breaking or
dropping of the King-bolt.
These felloe or sweep-pieces in the drawings horewith are shewn to be carried
on iron stays from the head block or carriage bed but other methods of supporting or
carrying them may be adopted without affecting the peculiar principal of the device
or invention.
The materials of which the felloe-pieces can be made are gun-metal, brass or
malleable iron.
The details of construction and arrangement are more particularly defined in the
drawings herewith.
The letters of reference on the several diagrams apply to corresponding details or
features in each.
Fig. 1 is a horizontal section or ground plan shewing the Wheel-plate with
the felloe-pieces, the head block &c. A is the Wheel-plate, B the head block or
carriage bed C. C. the folloo-pieces D. D. the stays. E the plate to which the felloe-
pieces are bolted.
Fig. 2 is a transverse section of the same showing the hinder felloe-pieces in
elevation; the profile of the head block or carriage bed &c. is drawn in dotted lines
to avoid confusion.
Fig. 3 is a longitudinal section.
Fig. 4 is a plan and Figs. 5, 6, and 7 cross sections (half the full size) of the felloe
or sweep piece and wheel-plate.-A. A. on Fig. 4 shows the position of bolts. Fig. 5
shews the felloe-piece without the flange 6 and Fig. 7 shews the manner of fastening
by bolting to the plate E which is supported by the stays.
In addition to the measure of safety affected by this device by securing the under
carriage in its place, in case of the loss or breaking of the King-bolt it is claimed
that considerable neatness, compactness' and cleanliness are also gained compared
with the old style where grease is used.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The arrangement or combination by which the wheel-plate is supported and
clipped by the felloe-pieces so as to allow of the rotary movement of the wheel piece,
and at the same time by means of the flanges or clips on the felloe pieces, the wheel-
plate is kept securely in its place, thus preventing accidents if the King bolt be absent
or broken.
Dated this 27th day of September 1886.
