Hard to believe there’s not a thread dedicated to the history and tools of H.D. Smith (est. 1855 in Plantsville, Conn.) here on GJ (woody must be slacking…, or I just couldn't find it!) 
I'm not going to repeat publically available information.
Alloy Artifacts has a short summary, and some examples, linked here.
The Tool Archives has a nice list of all the H.D. Smith patents, linked here, and linked also to DATAMP for more info and easy linking to the full patents on the USPTO site.
References to H.D. Smith and H.D. Smith tools show up here on GJ from time to time, usually associated with the screwdrivers that give all “Perfect Handle” screwdrivers their name, but they made several other types of tools with the “Perfect Handle” design, and believe it or not, screwdrivers were not the first – adjustable nut wrenches were.
I happened to find one yesterday, prompting this thread.
Easily 7 of every 10 antique era monkey wrenches I see are Coes. Every once in awhile I’ll see a PEXTO, or a Bemis & Call, or a Whitman & Barnes. I see so many here in NJ that I usually leave them behind. The H.D. Smith is the first I have ever seen in the wild, so I snatched it.
The patent dates you see are for D33,468, 666,629, and D34,136 in short successive chronological order from December 1900 to February 1901, and they all together make up the “Perfect Handle” design branded just beneath the dates.

Well, now there's a thread for the OEM and the first (Shepard) of the two "Perfect Handle" patentees.
