    Hi Geoff,
    Had a quick look online and found that Morse left the Morse Twist Drill and Machine Company shortly after setting it up according to museum records:
    https://www.whalingmuseum.org/explor...ng-aids/mss116
    So I had a quick look for patents on Datamp listed under the company Morse rather than the patentee Morse which lists the following:
    Patents for Morse Twist Drill & Machine Co.

    There are a lot of patents here but I’m not convinced that it is complete.
    You may also find more by searching for other patents by the listed inventors.
    There are a few of Morse’s patents listed also but nothing I could see regarding tapers.

    Thanks Hiroller, I use DATAMP a lot, it is a very handy resource but is reliant on contributors adding new information as it comes to light. That's why I was surprised not to find the patent on there, if it existed you'd think someone would have found it by now.
    I was looking on a American machinist forum and there was a conversation there, about a year old, on machine tapers etc the feeling I got was that the taper may have been invented, if not patented, earlier than 1864. A couple of names being kicked around are Samuel Colt (of shootin' iron fame) and the Scotsman James Watt.
    It shows how you can become bogged down. This came about by my trying to write an article for our HTPSWA newsletter about the Engineers Ratchet Drill mentioned earlier in this thread, and I thought I'd put in some info' about the Morse Taper used to hold the bits. As the old saying goes "when you're in a hole stop digging".
    Cheers,
    Geoff.

    Looks like there wasn't a patent for the Morse Taper. Tapers were in use by machinery companies for a while.
    Looks like Morse sent a copy of his tapers to the Feds in Washington and suggested they make it a National Standard - and they did.

    Rather than make money from a patent.
    He made a standard for the taper on his drill bits with the aim of them being able to fit every machine.

    Thanks Hiroller, it looks like that's that then.
    In my digging I did find a patent not shown in DATAMP which is for an earlier version of George Stetsons Twist-Drill Clearing machine. US patent 195963 October 9th 1877, assigned to the Morse Twist Drill & Machine Co.
    Thanks for your help it's much appreciated.
    Cheers,
    Geoff.
