.BaumBaum's version of *Yale's OB lock. They did use others,
but this is the most prevalent lock you'll find in Baums.
3 screw-change wheels
& a gravity-driven counterweighted fence.
Handle turns CW. Proper Dialing Sequence for these: LRL R to Stop.
Pickup differences were 7,14,24 (approx). Gates read 4-5 incs wide.
Contact points on this one were non-existent throughout the manipulation.
While servicing though -
had they been detectable - I figured CPs @ 87 & 95.
As you can see, the RCP would likely give the best info (
more gradual slope).
*NOTE: Keep in mind the drive cam is changeable in this lock, which could place
drop-in anywhere. If I recall, there were a dozen or so positions to choose from.
That being said, much of the literature I find on this lock suggests many come
to a final stop somewhere between 95 - 5. This tells me the CPs may often
be found within this general area as well - I'd say between 95 and 15.
But again, be on the lookout for contacts to pop up wherever.
The Spin:
Not much of a struggle or story to embellish upon here.
All three gates were found through sound and/or feel.
And revealed themselves in the glorious order of 123

An interesting tidbit on Yale OB & OBB SeriesOB is a 3-wheel lock. The OBB, a 4-wheel... at least that's what we've all read and been told for the last umpteen years! However, at one time there was some controversy surrounding these two titles and what each represented in terms of how many wheels the lock contained.
It was said that when Yale first published these lock offerings, the titles meant just the
opposite; OB (4) and OBB (3). And apparently some rather convincing evidence was presented to support this. But the powers that be wanted nothing of it.
Of course, most any text you find over the last 70+ years will show the OB as 3-wheel and the OBB as a 4-wheel lock. Hell, at this point, it's so deeply embedded in our lingo and text... I'd say it might just be a case of "
too little, too late". But it's funny to think, maybe... just maybe... we got it all wrong from the very start.
So how much does all this really matter? Maybe not much I suppose, lol. But it
is, as I say... an interesting tidbit
