Abstract
Abstract A plate cooling bed consists of a number of parallel shafts on each of which are mounted a number of equal discs which support and transport the plate. The shafts have no axial bearings, and, instead, each shaft is supported by a number of secondary discs, which have a diameter less than that of the support discs, and which are engaged by pairs of rollers beneath the shafts. Each shaft is driven at its ends.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
A transfer or cooling table or bed for metal products comprising a plurality of shafts spaced from one another in the transfer direction, each shaft carrying a plurality of substantially equal diameter product support discs spaced along the shaft and coaxial with the shaft, and, for the rotary support of each of the shafts, a plurality of secondary members on the shaft having surfaces of revolution coaxial with the shaft, but spaced separate from the support discs and with diameters intermediate the shaft diameter and the diameter of the support discs on the shaft, a plurality of rollers arranged to engage the secondary members below the level of the shaft, and to support the shaft through the secondary members, and means for supporting said plurality of rollers.
Claim 2
Dependent Claim
127 words
A transfer or cooling table or bed for metal products comprising a plurality of shafts spaced from one another in the transfer direction, each shaft carrying a plurality of substantially equal diameter product support discs spaced along the shaft and coaxial with the shaft, and, for the rotary support of each of the shafts, a plurality of secondary members on the shaft having surfaces of revolution coaxial with the shaft, but spaced separate from the support discs and with diameters intermediate the shaft diameter and the diameter of the support discs on the shaft, a plurality of rollers arranged to engage the secondary members below the level of the shaft, and to support the shaft through the secondary members, and means for supporting said plurality of rollers.
Claim 3
Dependent Claim
30 words
A table or bed according to claim 1 in which the support discs of each shaft are staggered in the axial direction relative to the support discs of adjacent shafts.
Claim 4
Dependent Claim
39 words
A table or bed according to claim 2 in which the secondary members of each shaft are staggered axially relative to the secondary members of adjacent shafts, and each secondary member is supported by a pair of support rollers.
Claim 5
Dependent Claim
48 words
A table or bed according to claim 2 in which the secondary members of each shaft are aligned with the corresponding secondary members of adjacent shafts and each support roller, except the end rollers in the transfer direction, engages and part-supports a secondary member on two adjacent shafts.
Claim 6
Dependent Claim
30 words
A table or bed according to claim 1 in which each secondary member is a disc having a diameter less than that of the support discs on the same shaft.
Claim 7
Dependent Claim
22 words
A table or bed according to claim 1 in which at least some of the secondary members are hooded against radiated heat.
Claim 8
Dependent Claim
26 words
A table or bed according to claim 6 in which each of at least some of the secondary members is enclosed in a double-walled cooled hood.
Claim 9
Dependent Claim
28 words
A table or bed according to claim 4 in which a number of secondary members which are aligned in the transfer direction are enclosed in a common hood.
Claim 10
Dependent Claim
30 words
A table or bed according to claim 8 in which the common hood includes means for forming a duct extending in the transfer direction for the passage of cooling gas.
Claim 11
Dependent Claim
28 words
A table or bed according to claim 1 in which each shaft is made up of two or more shaft lengths which are coupled together end to end.
Claim 12
Dependent Claim
22 words
A table or bed according claim 1 in which each of the shafts is driven at an end by an independent motor.
