Abstract
Abstract A longitudinal carriage drive for co-ordinates tables in machine tools for impelling the carriages on co-ordinates tables, particularly the longitudinal carriage, with the transverse carriage moving thereupon transversely to the longitudinal axis of the machine, and to the material to be punched held fast thereto, in which a power transmission by two screw-threaded spindles is provided to the left and right of the center of the machine, which receive their drive synchronously from a motor arranged at about the middle of the table.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A longitudinal carriage drive for coordinates tables in machine tools, particularly punching or stamping machines, for impelling the carriages on coordinates tables, particularly a longitudinal carriage, with a transverse carriage moving thereupon transversely to the longitudinal axis of the machine, and to material to be punched held fast thereto, with powertransmission by screw-threaded spindles, the improvement including, to the left and right of the center of the machine, two threaded spindles, a motor arranged at approximately the middle of the table, toothed belt drives between the motor and the threaded spindles for transmitting power to the spindles symmetrically arranged about Y-axis of the longitudinal carriage and electrical measurement-value receivers operably related with the toothed belt drives and, operative upon a disturbance in the state of equilibrium, to deactivate the drive.
Claim 2
Dependent Claim
130 words
A longitudinal carriage drive for coordinates tables in machine tools, particularly punching or stamping machines, for impelling the carriages on coordinates tables, particularly a longitudinal carriage, with a transverse carriage moving thereupon transversely to the longitudinal axis of the machine, and to material to be punched held fast thereto, with powertransmission by screw-threaded spindles, the improvement including, to the left and right of the center of the machine, two threaded spindles, a motor arranged at approximately the middle of the table, toothed belt drives between the motor and the threaded spindles for transmitting power to the spindles symmetrically arranged about Y-axis of the longitudinal carriage and electrical measurement-value receivers operably related with the toothed belt drives and, operative upon a disturbance in the state of equilibrium, to deactivate the drive.
Claim 3
Dependent Claim
17 words
The longitudinal carriage drive as claimed in claim 1, wherein said electrical measurement-value receivers are electric generators.
Claim 4
Dependent Claim
17 words
The longitudinal carriage drive as claimed in claim 1, wherein said electrical measurement-value receivers are light sensors.
