To the oldtime bodybuilders and strength athletes "Chest Development" used to mean stretching and enlarging the rib cage, not working the pecs (which is what it has become today.) The theory behind this was simple, the deep breathing from intense leg work (i.e. squats combined with light pullovers did so very effectively. Enlarging the rib box meant wider shoulders and a much greater potential for upper-body growth.
To make the technique more effective, a half-moon bench was often used. These unusual pieces of equipment used to be commonplace in many gyms although you're more likely to win the lottery than find one these days.
