Hammer for firearms - Patent 2176478
If you are asking about the Reg. U.S. Pat. Off. stamp on the back of the hammer, that's not for an engineering design. It's a trademark registration for the company's blue-heavy case coloring process. The same registration assertion is made on the back of the trigger as well. These patent marks were seen only in the late 1920s and 1930s, I believe. The fell off during military production in WWII and were not reimposed after the war.
The basic prewar hammer is sometimes mistakenly called a humpback hammer, but there is a profile difference. The standard hammer has a shallow dish at the top surface, while the humpback hammer rises straight to the rear without a dished upper surface. The top of the hammer thumbpiece is somewhat higher than it is on the standard hammer.
These are K-frame hammers, but the design distinction is the same. HB is on the left, standard on the right.
