[CW] Sideswiper Patent

[Richard Knoppow]

    Thank you for the telegraph history link. I thought I had 
seen another patent for a sideswiper, it must have been Ghegan's. 
Ghegan was a prolific inventor of telegraph equipment. I wonder 
if anyone knows anything about Wood. Wood's spring adjustment is 
something like what I was thinking about for the bug adjustment. 
Maybe a deep memory.
