Hello Everyone!
This curious item needs its identity.
I have no clue as to what this item is or what this item is worth.
Very unique item to say the least. The front of this reads " The Saybolt Standard Universal Viscosimeter made in U.S.A. C.J. Tagliabue Mfg. Co. New York Sole Sales Agent" The large insert chamber is made of Copper and the insert that goes inside the chamber is made of Brass. The 3 legged stand is made of some sort of metal.
This stands approx 13-14 inches high with a diameter of approx 9 inches.
Is there anyone who can tell me how old this is, what it is used for and how much this is worth that would be great.
Thank you and please enjoy the photo.
CHRIS.

Well, a viscosimeter is used to test the viscosity of a liquid/fluid. We use such an item in chemistry. This one is obviously very old as the newer ones are MUCH smaller and typically computerized. Other than that, I don't have any info for you. Very cool item!!
Here is a little more info:
Saybolt Universal Seconds (or SUS) is used to measure viscosity. The efflux time is Saybolt Universal Seconds (SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer, under carefully controlled temperature and as prescribed by test method ASTM D 88. This method has largely been replaced by the kinematic viscosity method. Saybolt Universal Seconds is also called the SSU number (Seconds Saybolt Universal) or SSF number (Saybolt Seconds Furol).
It would test the oil back in the day. Used by Oil Companies to test quality of oil once the hit the motherload. This one is old! I found info they were in business as early as 1900. Aslo found they made testing equipment for Standard Oil Company in 1933. So this maybe the time line for this item. Dave
Very cool and interesting item!
I did some research on your Viscosimeter and it was patented by Erwin R Lederer of Fort Worth, Tx on Feb 25 1928. The patent was assigned to Texas Pacific Coal & Oil Co of Fort Worth, Tx. Mr Lederer held several patents on equipment pertaining to oil products.
Thank you very much for the helpful information. This is one tough item to try and find a value on. I cant seem to find anything out on its value. Not many around, this is actually the only one i have ever seen in person or in my research. Thanks again everyone!
