Cable to have a vertical angle of 20° at minimum and the horizontal angle 120° minimum (the horizontal angular position of the cable on Kronfeldt's winch is 110°). It was agreed that the proposal for a spare drum appeared to be a questionable improvement owing to the weight of the cable, and no provision would be made for this unless it is considered to be specially desirable in the light of further experiments. On the other hand, the operator's seat would be accepted as drawn, i.e., in a net wire cage. The modified specification entails alterations to the following designs, which were practically complete. 1. The quarter scale of the winch on the trailer will require re-drawing. One week will be needed. 2. The rear paying in roller and switch are scrapped. The new design will take three weeks. 3. The layout of the gears and gear train will have to be re-designed to take alternative ratios. This will require about two weeks. 4. The drum winding in carriage is slightly modified to provide an inch gap between rollers and remove guillotine. Two weeks will be required. 5. The guillotine requires re-designing. This will take three weeks approximately. 6. The automatic brake and tensioner is a new design. Four weeks will be required. 7. The cable drum requires modifying and a guard should be added. Two weeks required. 8. Hand throttle, low design. Two weeks required. - Continued - | ||
