    Default NSW. Pneumatic curiosity

    For lovers of vintage curiosities!
    This appears to be some sort of pneumatic device which fits into a drill or mill and uses a tool for drilling, riveting or making vertical slots. The steel output shaft is 7/8” dia. and has a ½” by 20 tpi UNF female thread. I have no idea if or how it works. Copies of the texts of the two patents are included (10 pages) and can also be viewed on the IP Australia web site.
    The name plate has the following text:


    “ACE”
    PNEUMATIC UNIT
    FOR USE ON DRILLING & MILLING MACHINES, RIVETING, ETC.
    Manufactured under licence by
    EMMCO PTY. LTD.
    A UNIT OF “EMAIL”
    Patent No.162239, Application No. 34688/58



    Asking $10 plus any postage etc. but pickup from the mid Blue Mountains NSW preferred. Delivery to Western Sydney possible if you are happy to wait until I go in this direction.

    Could you post a pic or 2 of the ends as well? Might help to figure out just what the heck it's supposed to do...maybe pneumatic auto feed control?

    Default Curiosity details

    The pictures rotated when posted, the top is to the left. There is not much extra detail visible so I have scanned the patent which may be of more help.
