Abstract
Abstract A supporting device for a rotary table for a machine tool comprises support members disposed on a foundation on the opposite sides of a bed member in parallel to the direction of rectilinear feed of a table body for supporting the table body by the intermediary of hydraulic jack means provided at the opposite ends along the lengthwise direction of the table body; the supporting device further comprises bridge bed members disposed between respective support members and the bed member in parallel to the support members, and a pair of table body supporting bridge members having their respective leg portions slidably supported by the bridge bed members so as to be bridged over the bed member, the pair of table body supporting bridge members are constructed so as to be movable together with the table body along the bridge bed members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
In a supporting device in a rotary table, for a machine tool, of the type including support members on a foundation adjacent the opposite sides of a table bed member, along which the table body is linearly displaceable, the support members extending parallel to the direction of displacement for supporting the ends of the table body when the latter extends transversely of the table bed member, through the medium of jack means adjacent the opposite ends of the table body, the improvement comprising, in combination, bridge bed members on the foundation between each support member and said table bed member, and extending parallel to said support members; and a pair of longitudinally spaced table body supporting bridge members extending in bridging relation across said table bed member and each having a pair of leg portions slidably supported by a pair of said laterally spaced bridge bed members; said bridge members supporting the ends of the table body when the latter is oriented substantially longitudinally of said table bed member.
Claim 2
Dependent Claim
169 words
In a supporting device in a rotary table, for a machine tool, of the type including support members on a foundation adjacent the opposite sides of a table bed member, along which the table body is linearly displaceable, the support members extending parallel to the direction of displacement for supporting the ends of the table body when the latter extends transversely of the table bed member, through the medium of jack means adjacent the opposite ends of the table body, the improvement comprising, in combination, bridge bed members on the foundation between each support member and said table bed member, and extending parallel to said support members; and a pair of longitudinally spaced table body supporting bridge members extending in bridging relation across said table bed member and each having a pair of leg portions slidably supported by a pair of said laterally spaced bridge bed members; said bridge members supporting the ends of the table body when the latter is oriented substantially longitudinally of said table bed member.
Claim 3
Dependent Claim
28 words
In a supporting device in a rotary table, the improvement claimed in claim 1, including means interconnecting said bridge members for conjoint displacement along said bridge bed members.
Claim 4
Dependent Claim
35 words
In a supporting device in a rotary table, the improvement claimed in claim 2, including means selectively operable to interconnect said bridge members and said table body for conjoint movement longitudinally of said bed member.
Claim 5
Dependent Claim
44 words
In a supporting device in a rotary table, the improvement claimed in claim 1, in which the upper surfaces of said bridge members are in substantially the same horizontal plane as the upper surfaces of said support members, for cooperation with said jack means.
