| COPY. OY4.R.6.1.28. June 1st, 1928. TO: Mr. Ross. Mr. Nadin (England). cc - Mr. Caswell. Mr. Burton(England). Mr. Bailey(England). Mr. Bagnall. FROM: Mr. Olley. RE: SPRING DRIVE - SECTION 5020. Slipper Flywheel. Discs. The latest Russel woven discs are greatly improved in firmness of weaving. They are a tight fit on the spigot. The danger of spreading such as occurred before is less likely to trouble us. They are about .025 thicker than the first woven discs, but can be set to 170 lbs. ins. without difficulty. When first set they broke at 220 lbs. ins. and turned very smoothly at 170 lbs. in. Left overnight they broke at 260 lbs. ins. and turned at 170 lbs. ins. when turned the first time. Subsequently they broke at 220 lbs. ins. and turned at 170 as before. This is similar to all woven fabrics (non-impregnated) which we have used, and compares with the results obtained with the Spaulding 'soft-impregnated' fabrics which we are now using, except that the latter do not show higher figures for the "break" when left standing. Our intention is to send England a quantity of these "soft-Spaulding" as soon as we have a supply for production. Springs used were 20 A-10698. OY. | ||
