AUTOBIOGRjiPHY OF JOHN FRITZ 171
source of trouble, and also of all the compUcated machinery for conveying the power to the roUers in the tables. The next and most important thing to do to make the bloom¬ ing mill a grand success was a plan to convey the power to the rollers that would permit the raising and lowering of the tables and would at the same time drive them at any and all points within the travel of the tables. The device must be automatic, simple, and effective. AU these com¬ binations made quite a difficult problem to solve. A number of plans were suggested in my mind, and were well thought over, but aU lacked the one aU-important element of simpUcity, which I had in view when we started to build the miU.
I destroyed aU the bridges as I crossed over them. One plan was to use the power from the main engine to drive the rollers in the table. The friction clutches for driving and reversing the roUs were another problem — both had to be arranged for. The power to be used for driving the table rollers must be separate and must be used for no other purpose whatever. A two-cylinder engine of the proper size w^as the most simple way of getting the power, and by making it reverse, the friction clutches were dispensed -^vdth and became a curiosity of the past.
The only thing that remained to be done was to get some simple way of conveying the power from the engine to the table, and here for a time there seemed to be an insurmount¬ able difficulty in the way. As the roUers were not station¬ ary or fixed, having to move up and down, and to revolve at will in either direction, it was not possible to have a fixed or positive connection of the power between the engine and the table, as the distance between them increased and diminished as the table was raised or lowered. Many plans to get over this trouble were suggested and thought over, but all were compUcated, and would surely be cUfficult
