  • Mr Bleichert's cast spoked wheels

    I am researching the manufacturing technique of two turnwheels made by Adolf Bliechert in Leipsig Germany in 1883.
    The wheels ar 6' 8" diameter with 8 off 1 1/4" dia spokes cast into the rim and the hub.
    The hub is the interesting part, as it is in two halves each holdiing 4 spokes.
    The two hub halves are separated by spacers approx 11/16" and the hubs and spacers are held together by two shrink rings, one on each side.
    The hub is tightened onto the shaft with a single morse taper key, there is no slot in the shaft only the hub.

    I make the following assumptions:
    The hub is cast in two halves to prevent it breaking when cooling.
    The pre-made spokes are cast into the hub and the rim.
    The bore of the hub is machined after the spacers and shrink rings have been installed, to give a 1 or 2 thou clearance on the shaft to allow a light push fit.

    I make the following observations;
    The spokes appear not to have any protrusions, one connection is smashed and the spoke is cylinderical inside.

    How do I get photos into these posts?
    Are the spacers driven into the gap between the hub halves to put the spokes in compression then the shrink rings fitted to hold it all together, or are the spacers a slide fit and the shrink rings pull it all together and put the spokes under tension?

      I'm not a flywheel expert, but there are several who hang out on the Practical Machinist forums, in the Antique Machine section if you don't find good answers here. Construction of these types of flywheel has been discussed many times over there, and there are members wih personal experience. Many of these flywheels were cast as a single pour, then deliberately broken at the rim for installation. This leaves a unique jagged break that keys itself when put back together. Close examinaion of the rim would show this. Dennis

          Are these wheels for a bandsaw style headrig in a sawmill?

              Bleichert wheel hubs

              I have uploaded the photos of the wheels and hubs, so you can see that the split in the hubs is intentional and spacers are inserted.

                Mt Bleichert's wheels

                No, they are counter wheels for an aerial ropeway drive.
                The haulage rope passes 180 deg. around a leather lined groove in the drive wheel, then around the counter wheel, then around the second drive groove, then around the second groove of the counter wheel, then around the third drive groove then off to the drive.

                  No, I worte a book on the history of the Scenic Railway at Katoomba, N.S.W. Australia, and the aerial ropeway that these wheels were part of, was included in the book.
                  I am in touch with Peter von Bleichert in California, who has aslo written a book solely on Bleichert ropeways.

                      Post #2 above links to a thread with detailed instructions. Did
                      some step not work ?

                      Addendum: Do you have one or more images up at Photobucket or
                      an equivalent site? If so, please paste a link here, or better, in the
                      Photo thread.
