Slide Chart, MM Calculator

This slide chart has a plastic sleeve that holds a cardboard slide. One side of the slide has a table giving the properties of various forms of filter cloth and wire cloth. The other side has two graphs.
The Multi-Metal Wire Cloth Company distributed this plastic slide chart to allow its customers and potential customers to compare the flow rates and particle retention of various forms of woven wire and woven fabric. Results were based on observations carried out at Columbia University. A paper sticker attached to the back of the sleeve gives further details of the calculation.
A mark on the front of the sleeve reads: MM (/) CALCULATOR. A mark on the back of the sleeve reads: Multi-Metal (/) WIRE CLOTH COMPANY, INC. (/) 1350 GARRISON AVE. (/) NEW YORK 59, NEW YORK (/) PRINTED IN USA COPYRIGHT 1959. The slide and the paper envelope are stamped: SEP 18 1963.
This object came to the Smithsonian as part of a large collection of trade literature relating to meat processing donated by the Cincinnati Boss Company of Cincinnati, Ohio.
