So sorry it very clearly states that is is a projection: ON THE PROJECTION OF J.S. CHRISTOPHER.
No. Being based on something does not translate into that same something.
That
Local time chart patented by
Alexander Gleason was based
ON THE PROJECTION OF J.S. CHRISTOPHER.
I was created for Gleason who really was an "ardent" flat-Earther:Alexander Gleason, a civil engineer from Buffalo, NY, tested the flatness of the surface of lake Erie. He published Is the Bible from Heaven? (1890) and Is the Earth a Globe? (1893).
It was created based on "the projection of J. S. Christopher" though, I agree it was not created by J. S. Christopher.
First thing you wrote with any semblance of correctness.
I believe Gleason patented it as a time chart because there is no way that the US patent Office would patent a 
Flat Earth Map !
Believe what you want. You have nothing supporting your belief.
So sorry, Mr T. Lackey, but I certainly do have something very official supporting
my certain knowledge!
Read Gleason's patent application at:
US497917A, US Grant, Alexander Gleason, G09B29/14 Local time charts.
And here is the last part of that application. Would Alexander Gleason's own words adequate evidence?:
Thus the time stands all ready computed to any child who is able to read the time of day from the face of an ordinary clock. Again, in order to give the child the most simple lesson first I would get the difference of the time between the two places as above mentioned, then placing the arm G at twelve, of course the arm H will stand at five p. m. for London, and there is no computation or counting for the child to make; he thus reads the hour and fractional part thereof from the dial of the map. The utility of such a computating map will be obvious, not only to the school child but for an adult or oflicial person. The map is not so extorted as to lose the relative latitude and longitude of any places on the land or sea, but retains all latitudes and longitudes of places agreeing with other recognized authors; and as the proper relations of continents and countries all stand in their relative position to each other, they are thus impressed upon the mind of the student.
The extorsion of the map from that of a globe consists, mainly in the straightening out of the meridian lines allowing each to retain their original value from Greenwich, the equator to the two poles.
I claim as my invention: The combination with a time chart of a circular time dial encompassing the circular map, a disk or dial graduated and divided to indicate longitude and sun time on any meridian line or intervening lines, two indicating arms loosely pivoted to the center of the circular map, numerals indicating degrees of longitude on each of said arms, and a pivoted joint for holding said arms together so the friction between them will be sufficient to hold them one to the other at any point to which one may be moved on the other and permit both to be moved together by turning one, substantially as and for the purposes described.

You may now know because you read something, but as you can see from that source it is NOT a projection...it is an extorsion.
And do
you what
an extorsion is? Today it is mainly used in a medical context as:
extorsion
Medical Definition of extorsion
: outward rotation (as of a body part) about an axis or fixed point
And note that Alexander Gleason states, "The map is not so extorted as to lose the relative latitude and longitude of any places on the land or sea, but retains all latitudes and longitudes of places agreeing with other recognized authors" and "
The extorsion of the map from that of a globe consists, mainly in the straightening out of the meridian lines allowing each to retain their original value from Greenwich, the equator to the two poles".
He straightened out of the curved meridian lines of the Globe to the straight meridian lines of the "Gleason Time Chart" and "the relative latitude and longitude" on the Gleason Time Chart agree with standard maps.
But note that he says nothing about either distances or directions being preserved and they aren't.
And the fact the flat earth does not have poles is correct.
It has a pole.
Incorrect Alexander Gleason himself wrote: "from Greenwich,
the equator to the two poles".
And please note a couple of very knowledgeable flat-earthers accept that Antarctica is an island continent and that there is a single South Pole.
Tom Bishop makes no claim that the "Bipolar Map" is just as "basic continental layout" but Sandokhan claims his is
"THE TRUE Flat Earth Map". FE Bipolar Map
