Josh,
The circular part is the "float bowl cover" from a Zenith patent brass
updraft carburetor. Originally patented by Zenith (Societe du Carbureteur
Zenith) and licensed to several manufacturers, including Zenith of America
(who sub-licensed "The White Motor Company") which produced the one from
which your part came. This float bowl cover came from an updraft model
(similar to the Zenith Models "0" through "04" ... you can view pictures of
a Model 04 on eBay (this is a "plain" Zenith, without the White Motor
Company imprimatur, but I believe it is pretty much identical to the one
made/used by White, except for the "advertising" on the float bowl cover),
if you hurry ... the eBay sale ends in a day-or-so ... here:

Your carburetor may have been from a White industrial motor (I believe they
sold stationary motors for industrial applications ... like mills of various
kinds, including sawmills, but I believe these were identical to the engines
in their trucks, and only differed in the type of chassis they were mounted
upon), but could just as easily have been from a White truck of the period
(circa 1917-1918 is my guess for the time frame ... I dunno about Tennessee,
but in Texas, the small "peckerwood" mills of the era commonly used gasoline
engines scavenged from trucks, rather than engines designed/manufactured
expressly for industrial use ... and I believe the carbs on both the truck
and mill engines circa 1917-1918 were probably identical).
Also, the White Motor Company produced a truck specifically aimed at the
logging industry (so your parts may actually be from a logging truck, rather
than the mill ... or both ... since a "smart operator" would have the same
engine on his mill and all his trucks to keep things simpler in terms of
universality of repair parts ... I've included links to several of these
rugged early White logging trucks in action, below).
There is a nice illustration (and description of operation, also showing the
vacuum system) of a Zenith Model "0" (which is most likely the model of
carburetor your parts came from) in a 1918 U.S. Army carburetor service
manual, here:

Zenith (of Detroit) really became a mover-and-shaker in the carburetor
bidness after WWI (probably from the good rep and connections/contracts
gained from their widespread use in military vehicles) ... by 1921 (but the
design of their truck carburetors had changed from the earlier style of
yours, by then):
http://books.google.com/books?id=LLMnAAAAMAAJ&pg=PT596&dq=%22Zenith+carburetor%22&lr=&as_brr=3
http://books.google.com/books?id=UHEhAAAAMAAJ&pg=RA11-PA38-IA5&dq=%22Zenith+carburetor%22&lr=&as_brr=3
Early carburetor patent holders charged Zenith with infringing their patents
and sued in Chicago courts 1912 (this case file doubtlessly would lay-out
the history of patent claims in mind-numbing detail):

Here is a picture (from the White Truck archives) of a 1912-1914 White 5-ton
logging truck belonging to Savage-Scofield of Enumclaw, WA. This picture was
taken in 1915:

This pair of White trucks, hauled B-I-G logs in California in the 1920's:

White trucks were also quite useful and common in the period circa 1910-1920
for delivering other products, for example, beer (or shine *chuckle*). This
one is a 1911 3-ton White truck belonging to The Standard Brewing Company of
Cleveland, Ohio, where these trucks were produced::

Oh, the other part looks like a "threaded hose barb" used to interconnect
the vacuum tank (a necessary part of these early carburetor systems, see
manuals cited above) and the carburetor with rubber vacuum hose.
Bob Skiles (whose grandfather was an intinerant sawmill "filer" whenever he
wasn't "cooking shine," whose father was a sawmiller as a young man in the
Great Depression, and who, himself, has researched quite a few early
sawmills for archaeological projects ... and as a former U.S. Forest Service
archaeologist in the Piney Woods of eastern Texas and the Pacific Northwest
... and whose ancestors came to Texas from Tennessee 3 & 4 generations ago)
