Ransom Cook patent auger bit sets ... almost sets, that is.
There are two sets shown below because there appear to be two manufacturers, L&G (possibly Lamson & Goodnow of Shelburne Falls, Massachusetts, according to the Directory of American Toolmakers, Ed. by the late Bob Nelson) and perhaps Ransom Cook himself.  Note that there are no differences in workmanship or style between the two sets.  These bits will enlarge an existing hole easier than will Jennings bits.  They are mostly around 150 years old.
US Patent No. 8,162 by Ransom Cook
The patent text is so succinct that I present all of it, as shown at right.  Ransom Cook went on to have this patent extended another seven years (24 years in all) to June 17, 1865.  In the meantime, he got other patents, one a reissue of this patent, re-designated No.RE2,513 and dated March 19, 1867 with clearer illustrations but the same claims.  In the interim he patented a machine for making the augers, US Patent No.12,583, on March 27, 1855 as well the actual method of making them, in US Patent No.13,780, issued November 13, 1855. Below is US Patent No.RE2,513.

The drawings at left are much clearer than the ones in US Patent No.8,162, of which this is the re-issue.  The claims are much the same.

In addition to these two sets of Cook's patent auger bits, I have several additional sets to be sold as "surplus to my needs."

See: Set 3 - Three individual L&G Cook's patent 1851 bits.
       Set 4 -
Four of James Swan's more recent efforts.
       Set 5 - Three more L&G auger bits.

Set 3's three Cook's patent auger bits: Three L&G Mfg. Co. Cook's patent bits
Here's the logo impressed around the shank of one of the James Swan Cook patent auger bits (two images pieced together):

Contrast US Patent No.13,870, granted just 4-1/2years after US Patent No.8,162, for this mechanized practice that Ransom Cook developed for making his augers.

Just tell me the method, Ma'am (taken out of context):
