Can someone help me to identify this piece. Not sure if it is some kind of an old tool or a part of an old gun. Thanks for any help. It is marked Pat. D and has a date of May 9, 1876. Also marked manufactured by ??? tool co.

Go to this digitized Patent Gazette. Scroll down to Page 891 (page number printed on original Gazette) to "Titles, Drawings ^ Claims of Patents Granted May 9, 1876" and look for your item:
