thrown out as just
slogans. Very nice condition!
& Co. 64 Charing Cross London 6" Ivory Rule / Sector / Protractor for Architects / Navigation
This Ivory Rule is marked with the famous English engine, lathe, and tool manufacturer' name Holtzapffel
& Co. It is configured similar to a Architects Rule with numerous scales and
a protractor on the perimeter. Rules like this are usually found in boxed drafting sets, or
traveling Shagreen cases associated with navigation or architects. The overall
condition is very nice.
Grade Rod #218" by L. A. Batham Oakland Cal. I have never seen or heard of this
"Sub Grade Rod" before, and neither has Google. This unusual measurement device
is NOS in its case. Google does recognize the maker, and he was Oakland's
official draftsman back in the 1920s. He also lived in Chico and
applied for the chief engineer job there about the same time. That is
all the info I could find. No mention of a patent or reference to this
type of device would come up.
I am guessing that Mr. L. A. Batham was sent out to a lot of job sites to
measure footings and got tired of bending down to read the tape to see if they were the proper depth. Below
the name stamp is a window with a ruler that one would read the depth of the
footing or trench - below grade while holding it in the trench and reading
the scale while standing erect The total travel range of the
two sliding sticks is less than 2 feet. That is about what code here
calls for with footings and stem walls. That is my guess anyway.
