| Y1194 File in Clutch Couplings with copy of note to Mr Burt. Mr Royce 2.7.12. Re DeDion type of Universal Joint. BB5/L2712. You will notice from the minutes of the Committee Meetings that Mr Platford has had an isolated case or so of these heavy couplings giving trouble from knocking, notwithstanding the fact that only about 4 thous. clear- ance in the balls was allowed. Instructions have been issued for this clearance to be still further reduced and Mr Wormald has in hand arrangements for the accurate grinding of the spheres. In connection with this matter Mr Burt forwarded to Derby some weeks ago the attached scheme which has a bearing on this point, and I thought it sufficiently good to forward to you for your criticism. It is not a particularly easy job to make but would I think give no | ||
