Abstract
Abstract A control for an apparatus, for example, an operating table, having a plurality of parts for moving the parts of the table individually and selectively to any of a plurality of selected positions. The control is carried out by a rotated shaft having spaced cams on it spaced from each other for moving the individual parts of the table. Each cam operates its table part when the camshaft is moved to a particular position. The camshaft is moved by a threaded shaft which has nuts which are driven to any one of a plurality of positions by a motor controlled by manually actuated selector switches. The selector switches are connected in the circuit with the motor in such a manner that when a selector switch is depressed, the threaded shaft will be rotated until the cam is driven to a position where it opens the corresponding one of the cam actuated switches and stops the motor. The movement of the camshaft is in proportion to the movement of the cam on the threaded shaft. The switching is carried out through a system of relays such that the motor always drives the threaded shaft in the direction to move the cam by the shaft through a minimum distance to reach any new position. The threaded shaft may also be rotated manually to move the camshaft and thus control the several functions of the table by manual control. The control has memory through a series of electrical relays which determine the direction of the motor. It also has memory in that if the control crank is stopped with the cam on the threaded shaft at an intermediate position, the electrical control can take over and move the cam to the next selected position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
228 words
A control for a surgical table or the like comprising: a first shaft, a second shaft, first motor means connected to said first shaft, second motor means connected to said second shaft, a plurality of position switches supported adjacent said first shaft, connected to said first motor means, a plurality of manual-controlled switches each corresponding to one of said position switches connected to said first motor means, first cam means on said first shaft selectively movable by movement of said first shaft to engage one of said position switches corresponding to the said manual switch whereby when a said manual switch is actuated, said first motor means moves said first shaft, moving said first cam means to a position corresponding to the said manual switch which was actuated, a plurality of actuating members on said second shaft, each said actuating member on said second shaft corresponding to a particular one of said manual switches, and connecting means connecting said first shaft to said second shaft whereby said second shaft is moved to a plurality of positions, each said position corresponding to the particular manual switch which was actuated, said actuating members each being adapted to be connected to a functional element on said surgical table and being adapted to move said element of said table to a position corresponding to a said manual controlled switch which was actuated.
Claim 2
Dependent Claim
228 words
A control for a surgical table or the like comprising: a first shaft, a second shaft, first motor means connected to said first shaft, second motor means connected to said second shaft, a plurality of position switches supported adjacent said first shaft, connected to said first motor means, a plurality of manual-controlled switches each corresponding to one of said position switches connected to said first motor means, first cam means on said first shaft selectively movable by movement of said first shaft to engage one of said position switches corresponding to the said manual switch whereby when a said manual switch is actuated, said first motor means moves said first shaft, moving said first cam means to a position corresponding to the said manual switch which was actuated, a plurality of actuating members on said second shaft, each said actuating member on said second shaft corresponding to a particular one of said manual switches, and connecting means connecting said first shaft to said second shaft whereby said second shaft is moved to a plurality of positions, each said position corresponding to the particular manual switch which was actuated, said actuating members each being adapted to be connected to a functional element on said surgical table and being adapted to move said element of said table to a position corresponding to a said manual controlled switch which was actuated.
