What size breaker is there now? FWIW, every domestic electirc dryer I
have ever seen called for a 30 amp breaker, and a minimum of #10 copper
wire. If you already have a 30, I would try replacing it with a new 30
and see what happens. NO way should you put in a larger one. What brand
of breaker is it? If it is a Federal or Zinsco, you would be better off
replacing the panel. Besides being POS's, the breakers are VERY
expensive. Get back with more info. *Larry

The OP hasn't advised the size of the circuit breaker for the dryer
circuit that trips!
Also what is the gauge of the wire between the breaker and the dryer
socket?
Because the size of the breaker must not exceed 20 amp for #12 AWG or
30 amp for #10 AWG.
Another thought might be, in a very old house; is there anything else
connected to that same circuit breaker. You never know what might have
been codded up or hooked up temporarily years ago.
And yes it may just be a 'weak' old breaker.
It's kind of worrying to tell the OP, who seems to admit to limited
electrical know how, to, as a test, 'swap' the wires for that circuit
breaker onto another breaker of the same rating.
