Connectivity Within The Manufacturers
chitown (CHRIS) ... you really have discovered many connections within the manufacturers of early 1900's bicycles !!!
The illustration of the American DeLUXE 1911 does show a chainring design that was used on a Davis motorbike .. 'tho the
pitch is different (as you have pointed out). Evidently, The American Motor Cycle Co. was still using a two-piece crank on this
model. The pin-spanner-type locknut for the two parts can be clearly-seen in the illustration of their American DeLUXE
Model A of 1911 ... (chainring side, axel-base of right crank).
While the American DeLUXE Model A does have a two-piece crank ... it is very possible this crank may have a single, drive-pin
on the frontside of the right crank arm ... mating to a single, similar-size hole in the chainring.
The reader may now be asking, "Why bring this up ??!"
Could be that many manufacturers used a two-piece crank in these early years of the 20th Century. If one were to look at two,
Consolidated Manufacturing Co. ads from 1907 ... one could see the use of the two-piece crank on the Snell .. the Yale ... and
the Yale-California bicycles. The Yale-California Bicycle was produced as a Model of 1907, ONLY ... no other ads featuring this
bicycle have been observed by this writer ... and if any come to light .. they will be reported in The CABE.
The Snell and Yale cranks of 1907 did not make use of a single, drive-pin ... these rides featured the more-antiquated 'SPIDER'.
Although antiquated back then ... the 'spider' on a two-piece crank has been the way to roll on upper-end contemporary road bicycles.
Pause here ... and reflect on the reality that Davis purchased the Snell and Yale line from Consolidated in 1916.
Back to those two-piece cranks ......... The Snell and the Yale -- AS A DAVIS MAKE .. always had a one-piece crank. But ... as a personal
afterthought .. the Dayton (and possibly the Davis-Yale RACER) DID HAVE a two-piece crank ... with a single, drive-pin.

POST SCRIPT ... If you would like to follow more information on the Pre-Davis ... SNELL ... YALE ... and YALE-California Bicycles ...
you can do a CABE search .... "Question for PAT or anyone ..." ... started by SAM.
POST-POST SCRIPT ... 'tho it appears this writer has drawn many conclusions in this entry .. do not be lulled into a state of
absolute conclusiveness ... much more research is indicated before any real conclusions can be reached.
