| TBB8/L8912. Red file July 9th. 1912. Re Cotton Fabric Cone Clutches. With reference to your note of July 6th(attached) on the above matter, I am sorry that the question of cone clutches has caused you some annoyance and I am afraid I cannot have made the matter clear in the various minutes and reports I have written to you with regard to our present procedure and the behaviour of the wire stitching. When the trouble of the fabric leaving the cone first occured we immediately tried increasing the number of rivets as you suggested ( Mr Bailey increased them from 60 to 170.). The result of this was that the fabric did not leave the cone in the middle, but as soon as the material became soft with use, the strands at the edges of the cone opened out round the rivets in such a way that the rivets at these points could no longer do their work satisfactorily. The result of this test was the reason for the suggestion that the fabric should be stitched at the edges in order to prevent this opening out of the strands when the fabric became very pliable and loose. All the cones with fabric have since been stitched and the later ones have also been arranged with slightly modified rivetting in addition, with the result that Mr Platford reports that he experiences no difficulty whatever with regard to fabric leaving the cone. This matter has been in order for several weeks and X 356 | ||
