It is very curious to look at the patent illustration and not pick up on the inventors intention. I was going to post this 1911 Victor patent with the other posting of "Duck Web" gloves and read the document more closely and realized the inventor, Burt Rogers was describing the so called "Pita Pocket" glove. Rogers intended a flap of leather attached loosely to the face of a fielders glove (cross section of fig. 3) so said glove could function as a catchers mitt if needed. This flap of leather was to be attached at the heel and up the pinky and thumb with sewing or lacing and left loose up to the fingertips where each finger and thumb had a point of attachment. The reasoning was to leave the fingers with some room for movement and flexibility. There was some mention also of the attachments being manufactured so the leather flap could be removed and replaced if needed.
Glove below from http://www.baseballglovecollector.com Not sure if this is a Victor glove since no markings are evident, but it looks like the fingertip attachment points are crimped split rivets which could be removed as per the patent description. With gloves this old and un-marked, it is kind of a guess
The glove below has a similar look but the fingertip attachment points seem to be crimped metal grommets.
