Vintage Starrett center head showing patent date June 29, 1880. This is the issue date of patent 229,283 that Laroy Starrett obtained for the original centering head patent, described in the patent as a try-square head. An excerpt of the patent specification follows: _______________________________________________________________________________________________________ SPECIFICATION forming part of Letters Patent No. 229,283, dated June 29, 1880. Application filed March 29, 1880. (No model.) To all whom it may concern Be it known that I,'LAROY S. STARRETT, ofAthol, in the county of Worcester and State of Massachusetts,have invented anew and useful Improvement in Try -Squares; and I do hereby declare the same to'be described in the following specification and represented in the accompanying drawings, of Which- Figure 1 is a side View, and Fig. 2 a transverse section, of a try-square having its head or stock provided with my improvement, the said section being taken through the clamping-screw and nut, to be hereinafter described. Fig. 3 is an inner-edge view, and Fig. 4 a longitudinal section, of the stock or head. The trysquare hereinafter described is not only to be used as an ordinary try-square, but can be employed for determining the center of a circle. It is composed of a ruler or slidebar, A, and a slotted stock or head, B, the latter being applied to the said ruler and provided with a clamping-nut and screw for fastening it in position thereon. _______________________________________________________________________________________________ Manufacturer's usually don't use a patent stamp after the patent expires, which would have been in 1897. This strongly suggests that this center head was manufactured before 1900. Also, the acorn nut appears to be nickel coated steel, as it can be attracted by a magnet. I believe that suggests it was manufactured after 1885. The center head itself is in very good condition. There is no rust or pitting. The surfaces are very smooth with some staining. I hesitated to try to polish off the stains and will leave that decision to the next owner. I have described this item to the best of my ability. PayPal is the preferred payment method.
