Summary

Aeroscope hand pump to pressurise Mita high pressure burner illuminant. The aeroscope pump was invented by Kazimierz Prószyński in 1909 and was primarily used to pressurise the Aeroscope camera which was the first successful hand-held operated film camera. It was been powered by compressed air pumped before filming into the camera with a simple hand pump, similar to the one we still use to pump bicycle tyres. Filming with Aeroscope, a cameraman did not have to turn the crank to advance the material filming, as in all cameras of that time, so he could operate the camera with both hands, holding the camera and controlling the focus. This made it possible to film with the Aeroscope hand-held in most difficult circumstances, as well as made possible to film from the airplanes, also for the military purposes. Camera carried 400 feet (120 m) of 35mm film and, once pressurised, could work with no further pumping for up to 10 minutes. The Aeroscope was known for its simplicity and reliability. This pump has been used in conjunction with the Mita high pressure burner. It comprises a base plate with two fold up footplate and the outlet point which has a screw fit aperture. There are three brass cylinders the diameter of which reduce towards the outlet. There is a metal collar holding the cylinders together at the top. The pistons from the cylinders protrude and are extended by bolts through a stout wooden handle. On the largest cylinder is an embossed makers mark which reads " Triple compression pump then there is a picture of a mans head and shoulders with the word Handy above and H & D below Patented in England& abroad Hattersley & Davidson Ltd Sheffield"
