Best method to support joists in-line

The 3 pitch pine joists shown are cross section 9.5" x 2.25".
Supporting pitch pine beam is under joists as shown in picture below.
Beam is getting moved from under joists to end of the joists.
Plan to use joist hangers to connect joists to beam.

Anyone recommend correct good structural hanger for these old joist sizes. I can't find close size?
or ideas for best structural connection between in-line joists and in-line end beam?

 

Cullen multi hanger MHE maybe

A 63mm wide or 75mm wide hanger would work -put in timber packers either side

 

You could notch the front bottom edge of the support beam and the bottom of the joists to secure a slim steel under.
