PROVISIONAL SPECIFICATION left by the said William Morris at the
Office of the Commissioners of Patents on the 2nd February 1882.
WILLIAM MORRIS of Birmingham in the County of Warwick Manufacturer
IMPROVEMENTS IN TURNTABLES FOR REVERSIBLE CARRIAGES.
This Invention refers to improved turntables or apparatus for reversing carriage
bodies such as those of perambulators and other childrens' carriages and for
Stanhope or wagonette phaetons or other description of carriage in which the body.
or any part of it may be required to turn upon an axis.
With this view I form two rings of metal the one to be secured to the upper
side of the platforin or under carriage and the other to the underside of the body
A turning pin secured in the platform or under carriage passes through the centre
of both rings the carriage body working somewhat freely upon it; the platform
ring is furnished with a metal ball housed in a socket beneath the ring and pro-
truding through the ring about one third of its diameter; the counterpart ring on
the carriage body is provided with holes or sinkings at intervals at the bottom of
graduated grooves so that as the carriage body is turned upon its axis it passes
over the ball until one of the holes or sinkings is reached when the upper ring
closes over the lower one and the ball keys both in position Several balls may be
used if preferred, or friction rollers may be employed instead of balls.

"IMPROVEMENTS IN TURNTABLES FOR REVERSIBLE CARRIAGES"
This Invention consists of improvements in turntables or revolving mechanism
to be fixed between the bodies and frames or under carriages of vehicles in which
it is required to alter the position of the carriage body upon its under part and is
intended more especially for childrens carriages.
Figure 1. shew's a ring of metal to be attached to the outside of the carriage
bottom this ring is formed with graduated curved section grooves, a, gradually
deepening from nothing at b, to sockets or piercings c, through the ring at
the back of the holes c. the wood of the carriage bottom is socketted out slightly
so that the holes, c, are over the sockets or for heavier work sockets may be
formed in the ring instead of holes pierced through, d. is the centre pin passing
through the bottom of the carriage body and the under carriage or frame.
Figure 2. is a second ring secured to the under carriage or frame and having a.
. bevilled section hole cut through at e to receive a steel ball, f inserted in a
socket at the back before the ring is attached the ball works freely in the socket
in every direction these parts Figures 1 and 2 being secured in their respective
positions and the two parts of the vehicles connected by the centre pin, d, the
ball, f, acts as a key in keeping the body steady on the frame so long as either of
the sockets, c, is over the ball but a slight pressure in the direction of turning
the body either way will allow of its being placed across the frane or entirely
reversed at will the ball acting as a friction roller as well as a key and graduated
grooves .a. assisting the action.
Figures 3 and 4 slew another form of the same principle in which a friction
'roller, g. is mounted in a slot in the ring, Figure 3 working into slots in the ring
Figure 4. the graduated grooves in the ring-Figure 4 being in this instance_flat
section instead of curved to suit the form of rollers, the relative positions of these
rings may be reversed if expedient the sunk ring may be on the under carriage and
the roller on the body in either case the keying action is the same and the positions
of the body on the under carriage will be maintained without bolt or spring action
of any kind thus avoiding the rusting and destruction of bolts or springs by wet
getting between the body and the under carriage.
Having thus described the nature of the said Invention and the manner in
which the same is to be performed I claim the improvements in turntables for
reversible carriages by the employment of friction rollers or balls working in
graduated grooves and keying into slots or sockets substantially as herein more
fully set forth and specified.
In witness whereof I the said William Morris have hereunto set my hand and
seal this first day of August in the year of our Lord One thousand eight
hundred and eighty two.
WILLIAM MORRIS. (L.S.)
