Most of the 1890s frames that appear as you describe are internal lugged. The internal lugs usually had long spear points similar to the external ones we are used to seeing. Some were formed sort of like the lower case "e" when viewed from the end to increase rigidity. Brazing was usually accomplished by a brass "charge" which was also inserted with the lug and/or a paste of brass powder and flux. This made for a tidy braze joint when the frame was heated in a forge.

We've all see the REALLY old , circa 1890's frames , with some tubes perfectly mitered , and stuck together with no lug , no fillet , no visible means of connection . The steel tubes look as if they were simply glued into place . That's runny brass brazing .
But with more viscous bronze , you can build up a nice fillet . >>
Nope... all the same... with more 'filet" or less build up on the inside or outside of the joint, but all really just techiniques within the same basic joining method..
