Interesting show on the Computer Garage

Hmm not just that, there was a gentleman by this Ingersoll who invented inexpensive watches by using stamped plate movement on hollow pillars riveted to one plate, tapped for screw to secure other plate. Both plates has stamped out and drilled holes for bearings and key items by the "bridge" plate over one of pillar with a screw like escapement lever and balance wheel. Also did this also with hardened steel conical bearings design. Balance rests it's snightly rounded points in a small rounded bottom of conical caps instead of expensive drilled brass and hardened end plates for steel or jewels for balance wheels. Two more innvotive items that made this watches cheaper in that old days was the main spring made weaker and thinner and the barrel mainsping sits in more large with fiction fit for time adjustment gear to drive both hour and minute hands. Finally the escapement lever and it's escapement wheel, The wheel has series of "nubbins" stamped out of brass plate to draw in the two pin lever while out of engagement with balance wheel and when tripped imparts impulse to the balance wheel. All of this makes this design bit more durable in use and rough handling. Wear problem is not a big issue on a well built Ingersoll watch types if the steel is good quality and brass work-hardened properly. Worn bits is easily repaired or replaced quickly and easily. Cannot do this to Timexes it's too low quality. At that time manufacturing process was mostly milling parts out of brass either by hand or machine and less on stamping process. At same time many of them were hand-made or hand-built out of pieces and individually adjusted. If anybody have worn out wind up timex watches snap the back off and look, failing that, find a old westcox clock and unscrew back off. That's clone of Ingersoll's design mostly, if you manage to have a true photo or diagram of Ingersoll's design, it's completely different but the idea is remains the same. Cheers, Wizard
