Here is a series of articles starting in 1913 discussing chucks. First, you get photos and discussions on a couple of unusual chucks patented in England, but probably never marketed successfully.
Then you get a lengthy two part article on lathe chucks - the types then in use, their design, and their advantages. Chucks began as dogs on face plates and evolved into scroll chucks. You'll see self-centring bell chucks, brass finisher's "clamb" chucks, wrench operated collet chucks, ways of locking internally threaded work, false jaws for collets, reversible dovetailed jaws, wheel chucks for holding disks, and all kinds of work holders not normally seen these days.
You also get a lengthy article on drill chucks. Here you'll find a great variety of designs with ball bearings, roller bearings, pivot cam jaws, automatic chucks with floating drive, and much more. Lots of cross-sectioned drawings. History and ideas galore....
Really fascinating is the series of letters written to the magazine over more than a year's by machinists debating the best way to true up worn chuck jaws. It's fun to sit in and listen to these experienced machinists argue about why the other guy's method won't work so well, and how they have a better way of doing it.
Even if you never have to true up your chuck jaws, just the debate that rages will teach you important lessons not only about machining, but about thinking through a problem in general.
