Well since my handle's been invoked (like saying "Beetlejuice" three times...) I'll weigh in with a few thoughts in no particular order:
-
https://www.garagejournal.com/forum/threads/mechanics-tool-forge-company.278029/ is the thread I posited the thought (with pics) that Wright may have made the early slide button piston pawl MAC ratchets. A couple pics got flipped around - the "first pic" appears to be the third now, and the Speedmaster/Wright Stone patent ratchet is still the 2 pics with the screwdriver underneath but out of order. I'm still gonna stick to that thought since the Pugh patent isn't assigned to any specific company, and MAC has clearly obtained ratchets from a variety of manufacturers over the years until they settled on their own unique pear head design some time after the split with/from MATCO.
- Despite never finding any Herbrand patents for their specific vertical and later horizontal slide button shifters I'm absolutely confident they made those ratchets themselves, and any other brands that show up on those designs were either sourced from Herbrand or via one of the later tool conglomerates that owned Herbrand (Kelsey-Hayes, Triangle, or Cooper). The Bonney ratchets (1/4" and 3/4" & larger) of Herbrand design most likely date from the time after Bonney was acquired by K-H (1964) and who already owned Herbrand (1961). The 1967 Bonney catalog illustrates the 1968 (applied for 1966) Kelsey-Hayes Rozmus patent dbl pawl round head ratchets for 1/4" & 3/8", the much inferior small pear head ratchet for 1/2", and the Herbrand slide shifter ratchet for 3/4" & 1". The 1966 Herbrand catalog illustrates the slide shifter for 1/4", 3/4", & 1", and the inferior small pear head for 3/8" and 1/2". My hopeful guess is that the inferior pear head design came from K-H, but it may share some basic design commonalities with either the 1960 Bonney Hare or 1962 Bonney Peters patents - been awhile since I had a small pear head apart and my memory's getting fuzzy.
- Bonney produced a slew of different ratchet designs over the years prior to getting Borg'd by K-H - almost looks like they changed up every few years or so (have only found a few patents) until K-H acquired and settled on the superior Rozmus design, IMHO the very best ratchet bearing the Bonney brand (and several others), even though it is kinda fat/thick and not the best balanced - it sure seems bulletproof.
I only have a handful of catalog pdf's, would luv to get a bunch more for Bonney, Herbrand, Billings, and others from the 50's thru at least early 80's.
