DeVry 35 mm

DeVry 35mm film projector. Projectors of this model were first produced around 1935 and played optical sound from the film. The machine has a filament lamp, which was both an expensive and inconvenient light source. The machine projected 24 frames per second and could handle a film up to 20 minutes long. Therefore, two machines were usually run in tandem. The machines projected at 24 frames per second, the speed used to synchronize sound and picture. 24 frames per second is therefore the speed of the film through the projector. If it was shown too slowly, everyone would have become deep-voiced; if it was played faster, everyone would have become very shrill. The projectors were used at the movie theater in Hotel Ljósbrá in Hveragerði and were owned by the couple Sigríður Björnsdóttir and Eiríkur Bjarnason of Ból, where they ran an extensive catering business and a movie theater for decades. Previously (from 1945 until around 1975), they made countless trips all over the South Coast with their traveling projectors, showing people movies from the movie theaters in Reykjavik, often under difficult conditions and in bad winter weather. For a long time, Sigríður was the only woman in the country with a license to show public movies. Similar projectors were popular in the country and were widely used in places such as the Tripoli Cinema (later moved to the Tónabíó), Hafnarbíó, and Austurbíó. The American military used these machines extensively, which was the reason for their popularity.
