  We present orbital elements, orbital parallaxes and individual component
masses, for fourteen spatially resolved double-line spectroscopic binaries
derived doing a simultaneous fit of their visual orbit and radial velocity
curve. This was done by means of a Markov Chain Monte Carlo code developed by
our group, which produces posterior distribution functions and error estimates
for all the parameters. Of this sample, six systems had high quality previous
studies and were included as benchmarks to test our procedures, but even in
these cases we could improve the previous orbits by adding recent data from our
survey of southern binaries being carried out with the HRCam and ZORRO speckle
cameras at the SOAR 4.1m and Gemini South 8.1m telescopes, respectively. We
also give results for eight objects that did not have a published combined
orbital solution, one of which did not have a visual orbit either. We could
determine mass ratios with a typical uncertainty of less than 1%, mass sums
with uncertainties of about 1% and individual component masses with a formal
uncertainty of $0.01 M_\odot$ in the best cases. A comparison of our orbital
parallaxes with available trigonometric parallaxes from Hipparcos and Gaia
eDR3, shows a good correspondence; the mean value of the differences being
consistent with zero within the errors of both catalogs. We also present
observational HR diagrams for our sample of binaries, which in combination with
isochrones from different sources allowed us to asses their evolutionary status
and also the quality of their photometry.
