Deflection tests for a bumper chassis, detailing reductions in frame movement and the importance of a rigid dash attachment.

| -2- On the bumper chassis we have taken deflection tests and have reduced the frame movement by 60% by using Fig.II. The external connection between the dash and the frame reduces the frame movement by 30%. For both 25HP and P.2. we find a rigid attachment of the dash to the top of the frame is important. On P.2. we used the bracket R.6520 as shown on R.6519. If the frame deflections was eliminated we still have deflection in carrier brackets. We like R.S.3999 as this overcomes frame and carrier bracket deflections. Attached 2 prints. Hm{Capt. W. Hallam - Head Repairs}/ I.A. Leslie. | ||
