I have the same model glove with the same patent stampings on it. It's an unendorsed Professional Model, not a Bill Doak glove. The Aug. 22, 1922 stamping just covers the features that Rawlings and Bill Doak patented; the laced web and the thumb seam protector. Not sure what the Nov.21, 1922 patent covered. Maybe it was the change to having the eyelets and web on the back side of the finger and thumb? Very neat glove. I like the Standard Collegiate Supplies Company tag on yours. Mine just has the Rawlings tag.
Here is the original Doak patent drawing:
