This photo shows one of the pulleys. Notice that a Cotter Pin has been inserted throught a hole drilled in the bracket holding the wheel. Its purpose is to prevent the cable from jumping off the wheel when the mast is stored for transport.
A side view of the pulley showing how close to the wheel the Cotter Pin is placed and how the Carter Pin is folded to retain it.
This shows the new addition to the pump design. It consists of a box that encloses the cable/pulleys and acts as a guard to prevent injury in case anything such as a finger were to be caught between the cable and the wheel of the pulley. It is made of pieces of plywood seperated by two solid blocks cut from scraps of a 2 x 4. The largest piece of plywood used for the back is 14 inches x 5.5 inches. The smaller pieces are 5 x 5.5 inches. A waterproof glue such as Titebond III should be used to glue the assembly together. Small nails hold the plywood in place until the glue dries.
This shows how the box mounts around the pulleys by being screwed to the cross-piece of the upright post. The cable is not shown.
This is a view with one side of the plywood removed to show the placement of the pulley.
As of now, the Assembly Pages do not contain drawings for this protective cover, but they will be added later. We felt that with the possibility of children using the pump or assisting with operating the treadles by facing backwards while another person faces forward, there was a danger of getting fingers or hair caught in the cable/pulleys. This guard should prevent this from occuring.
