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!

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?
