Dacor Diving Lung Dial a Breath 1959 #7776
The Dacor Diving Lung Dial-a-Breath regulator, introduced in the mid-1950s, represents a significant advancement in scuba diving technology. Developed by the Davison Corporation (Dacor), this regulator offered divers enhanced control over their air supply, marking a pivotal moment in underwater exploration equipment.
Historical Background
Founded in 1953 by Sam Davison, Dacor quickly established itself as a leader in diving equipment innovation. By 1955, the company introduced the Dial-a-Breath regulator, allowing divers to precisely adjust their air intake, thereby improving the underwater experience.
Design and Features
The Dial-a-Breath regulator was a two-stage, double-hose system featuring a unique adjustable vane mechanism. This mechanism enabled divers to modify the breathing resistance by turning a dial, providing personalized airflow control. The regulator’s construction included two diaphragms: an internal diaphragm on the inhalation lever assembly and an outer diaphragm incorporating an exhaust valve. This design aimed to circumvent existing patents and offered a distinctive approach to breathing regulation.
Models and Production
Dacor produced several models of the Dial-a-Breath regulator:
- Model R-1 (1955-1956): The initial version featuring the dual-diaphragm design.
- Model R-2 (1956-1959): An improved version with minor enhancements, including a single filter screen and longer, crush-proof hoses.
- Model R-3 (1959-1962): Known as the “Dial-a-Breath,” this model introduced the adjustable vane system, allowing divers to control airflow resistance.
Impact and Legacy
The introduction of the Dial-a-Breath regulator marked a significant step forward in diving technology, offering divers unprecedented control over their breathing apparatus. This innovation contributed to safer and more comfortable underwater experiences. Today, the Dacor Diving Lung Dial-a-Breath is regarded as a classic piece of diving equipment, valued by collectors and diving history enthusiasts for its unique design and historical importance.
In summary, the Dacor Diving Lung Dial-a-Breath regulator stands as a testament to mid-20th-century ingenuity in scuba diving technology. Its innovative features and impact on the diving community underscore its enduring legacy in underwater exploration.
