There's a chamby patents listed here but I can only get one link to work properly. Can anyone else? I think the final version of the M1 etc was more refined than suggested here. Interesting site if you want to know about and hear optigans/orchestrons. www.optigan.com/archives.html John

I have a collection of 49 images of pages of what must be most if not all of Harry Chamberlin's patents. I believe I downloaded these from the USPTO based a search started from that one patent that is readable from optigan.com. The drawings of the rewind mechanism of the M series are included here, along the earlier Musicmaster machines that formed the heritage of the Mellotron Mark I/II. They are quite fascinating as are the descriptions of the various mechanisms. I've had these for a while and they deserve to be seen by anyone who is interested. I guess I always intended to upgrade my Mellotrons and Chamberlins Web site and put these there, but that's just not happened. I would be glad to make these available to anyone who wants to host them on their Web site. A second, less desireable option, would be the yahoo file area, but this limits the audience to just members of this list. There are something around a megabyte's worth of files. They are all in 'png' format which is not the most common, but most browsers these days can handle them. They would need sorting and indexing by era or machine type. On a personal note, I would like to say that I'm am quite pleased to see the interest in the Chamberlin machines here lately. I believe Mellotron fanatics everywhere owe a huge debt to Mr. Chamblerlin and these patents help to demonstrate that. Bob S. J.K.Beresford wrote:

The European Patent Office keeps a really nice collection of complete patent scans. These are in PDF format so they print out especially nice. So all you need to do is reference the patent at the EPO web site. I do this all over my ARP patent page and my Moog patent page.

Thanks for the tip Don. The EPO versions, in addition to being in PDF
format, are much higher quality scans than the USPTO. Each page of a
patent is a separate PDF document though so you have to pull each one
down separately.
Harry C's patents, at least the ones that I have found, are:
2910298
2940351
3250847
3272907
3278188
3567840
Check them out, the drawings are fabulous. Use Don's link below and key
in the patent number with a "US" on the front.
Don your patent pages are great. Have you considered adding a Chamberlin
page?

Holy moley those are great! The first few are what appear to be the Chamberlin 200 with the arched-steel-rod springs (am I right?). Then there are some very MkII-looking drawings (the 600 maybe?), and the second-to-the-last is the Rhythmate (one of which currently sits taken apart on my workbench). The last is the M1 motor-return mechanism which is giving me so much concern at the moment. And the rivets are shown as press-fit! Yay! - Gene M400S #1023 M400S #1213 M400S #1289

I actually wasn't aware of the Chamberlin patents until now. I suppose I could write up a Mellotron patent page, but that would take some time.
