I have what looks to be a doorbell that is marked "Baldwin,s Patent" (no the comma is not a mistake) then underneath is Marked "Mar 16, 1869".
Johnny, the , (comma) at the end of the name instead of an ‘ (apostrophe) could have been a simple mistake of the “mold maker”. The lettering on the mold itself has to be ….. auto-positive in reverse.
It has 5 levers that push against the flapper that protrude from the bottom board.
And Johnny, what exactly is that 4th picture of? Are those 4 “white” pins what you are calling “the flapper”?
And, 1) should there be 5 of them, ….. 2) do they move downward as the levers are pulled, …. or …. 3) are they also “spring loaded” and plunge downward like the one that strikes the bell?
Anyway, looking at the “sawed” hole in the bottom board with the saw “cut” extending farther than necessary and the
, (comma) at the end of the name instead of an
‘ (apostrophe) , ….. my guess is that was a “prototype” unit, ….. and possibly an “experimental design” for a per say …….
employee work clock that was impractical for actual use.
Given the five (5) levers, it could accommodate up to 31 employees using a “binary code” of 1 to 31 with said code being imprinted on a “daily work card”.
The first practical “time clock” was not invented until November 1888.
