Strength for the Ages
Unlike today’s consumer culture that has been instilled with the seemingly industry standards of “planned obsolescence,” stoves of the 1910s to 1930s highlighted the importance of strong and durable appliances. Across all types of ranges, from the more traditional wood and coal stoves to electric and gas ranges, they all speak on some level of their strength that they will last and withstand daily use. This description of stoves being good to be relied on seems to reference the expectations to depend on a husband, and that he will do what he needs to do to support your family with what they need.
Especially for kitchen ranges targeted in their titles at more rural settings they emphasize how they will last long and will hold up. An example attached is The Old Homestead range, which they describe in the add as "a monument of strength... built to give a life-time of service—and longer."
