Testing Turbines at Westinghouse Works. Hign ang. shot of 2 machines set up side by side both of which are being checked by workers. On the left of the screen, a small group of men lift the top off of what appears to be a turbine with a crane and continue to check the machine, tightening various parts with wrenches. On the right side, a few men appear to be testing the workings of another machine like this.
