Handbrakes

I understand that in 1937 power (geared) handbrakes required on all newly-built or newly-rebuilt cars. Were non-power handbrakes every specifically outlawed or banned? Bob Chaparro Hemet, CA

Bob,
Since about 2005, a list of the AAR interchange rule dates has been posted in the FILES section of this group 😉 It is even in both WORD and EXCEL formats depending on your preference.
That file, when searched for "geared" or "power" yields the following:
January 1, 1937, "Geared handbrakes required on all newly-built or newly-rebuilt cars."
There is no subsequent ban (AAR interchange) or outlaw (Federal law) date given for geared handbrakes. Regards,

"Many vertical shaft/horizontal wheel installations had gearing to assist the brakeman in applying the brakes and would therefore have been considered "allowed" under these rules."
Yes...two examples from my own files. The first photo is from 1957 and the second no earlier than 1960. Bob Chaparro Hemet, CA

As a reminder to some of our list members, geared (or "power") handbrakes does NOT mean exclusively horizontal shaft/vertical wheel handbrakes. Many vertical shaft/horizontal wheel installations had gearing to assist the brakeman in applying the brakes and would therefore have been considered "allowed" under these rules.Yes, they were quite wide spread and hard to spot, since unlike Bob Chaparro's example which had the reduction gearing up at the roof eave, most examples brought the brake staff all the way down to the end sill, and tucked the reduction gearing beneath the sill. Anexample would be the CP "mini box" recently discussed: http://lists.railfan.net/erielackphoto.cgi?erielack-06-28-19/X7177.jpg I've also found similar gear on a 1926 Soo Line box: And also on the Soo's 1936 copies of the 1932 ARA car: Note this later car also has a square brake staff.

The C&O also had a similar geared brake design, an example can be found on Erie 1932 boxcars also w/square brake staff.

But the point is, it's obvious, with that large gear housing at the eave line, it won't be mistaken for the old time 'stem winders'. It also uses a chain, rod and bell crank rather than a simple brake staff. My point was a reasonable number of vertical staff hand brakes also used reduction gearing, but the gearing was almost hid under the end sill. Dennis Storzek

Hello, Milwaukee Road stock cars built in 1929, have the same appearing hand brake. The car diagram page states it is a Klassing Hand brake. Ted Schnepf 126 Will Scarlet, Elgin, Ill. 60120 847=697-5353

Dennis I'd really like to see the reduction gearing you're describing. I've never seen an example of that. They used a pawl and ratchet but that's not a gear box - it gives no mechanical leverage. Tim O'

Photo of the C&O type is in the 1932 Boxcar book. Look for the "B" end photo of the ERIE car. I modeled using 1.5 Grams of watch parts ordered through eBay. Plenty of actual gears to choose from.

Wow Bill, I had no idea! What a gold mine of precision made junk! :-)
