Prototype Hand Brakes

Gene Green <willibecher@...>
Please help me compile a database of hand brakes used on freight cars
built between 1937 and 1960 inclusive. Column headings are listed below. If anyone can contribute information I would be much obliged. I have found the best source to be equipment diagrams although, in my experience, the hand brake model designation is seldom included. Construction dates of the car series helps because, to the extent that a hand brake manufacturer had only one suitable model, one can make a supposition about which hand brake might have been applied. Before 1950 each hand brake manufacturer supplied a proprietary bell crank or, much less often, a sheave wheel. Information on these bell cranks, if available, would be listed under NOTES. 1958 was about the end of the malleable (cast) hand wheels unique to each manufacturer. Hand wheel information, if available, would also be appreciated. At present the database contains 299 car series. I would be happy to make any information I have available to anyone with an interest. Five items marked with an asterisk constitute the minimum data acceptable for an entry. RAILROAD* QUANTITY (of cars in series) SERIES* (number series) TYPE (of freight car) CAPACITY (nominal capacity of car) BUILDER BUILT* (year is sufficient but more precision is desirable) LOT (number) or ORDER (number) INSIDE LENGTH HAND BRAKE MANUFACTURER* HAND BRAKE MODEL DESIGNATION SOURCE* (of hand brake information) REFERENCE (to hand brake manufacturers drawing) NOTES Gene Green |

Sounds like a very worthwhile project. I'm in, but I've already come up with some questions... First...For those of us so inclined to send a data file...What file format would like people to use in order to minimize the effort for you to incorporate it into the "larger" database? I'd assume that you'd like a data record with the same number of fields. Second...How would you like "rebuilt" cars handled? i.e. a car built during 1937-1960, but rebuilt after its original build date? Obviously, the car could have the original hand brakes, but that assumption may not necessarily be valid. Would you like an entry in "Notes" about the rebuild date that was known from the equipment diagram or other source? Kind regards, Rob Adams Gene Green wrote:

Would you like an entry in "Notes" about thesource? Good questions, Rob! Most folks use Excel nowadays and I know I can open those with my antiquated software although, just now, I've forgotten how I do it. (For those who don't know I'm still mostly operating in MS-DOS 6.22. Screw Windows) I really prefer a text file which would be adequate or a comma delimited which is ideal. Rebuildings: Cars built before Jan. 1, 1937 might not have a power hand brake but, if rebuilt after Jan. 1, 1937, would be required to have a power hand brake applied during rebuilding. In those situations the date REbuilt would be substituted for date built. For cars built after Jan. 1, 1937 and rebuilt Jan. 1, 1937 would, in most cases, retain the same power hand brake because power hand brake applications after Jan. 1, 1937 were "grandfathered in." For situations I haven't anticipated, use the REMARKS column. For Mike Brock: Do you want this handled off list? Or do you think others might like to see the data as it comes in? Gene Green |
