The flow table shall consist of an integrally cast rigid iron frame and a circular rigid table top. Other details of the flow table, its mounting and lubrication are described in the specification. The conical mold for casting the flow specimen and the caliper for measuring the diameter of the mortar after it has been spread by the operation of the table are also discussed.
