W. E. Casey to R. B. Davis on Answering Dr. Gray's Dust Survey (1940)

A two-page memo of May 3, 1940, from W. E. Casey of the Raybestos Division at Bridgeport to R. B. Davis, headed "Dr. Gray's Report," setting out what the company planned for the four operations the state's survey had named. A suction line would be run to the hood over the pulverizer's feed hopper; the two bagging spouts would get rotary valves and canvas pipe sections; the roto-can exhaust had been revised along Mr. Postman's suggestions and was being installed; and two schemes were drawn for the barrels and weighing station. Casey favored the cheaper first scheme ($125 against $397 installed), which also left the operator more room to scoop from the barrels. He asked Davis to thank Dr. Gray for courtesies to J. F. Fenning at the Hartford meetings.

What it shows

The memo shows Raybestos-Manhattan answering the Connecticut Department of Health's April 8 letter (Dr. Gray's letter) with specific engineering changes and sending its drawings to the state for comment. Cost and the operator's working room both figured in the choice of exhaust design for the barrels.
