Chronology of cameras Gillon 

Traduction de Manuel M

This camera, imagined by Mr. Schlesinger and built by Mr. Gillon, introduce several very interesting features.
It is provided with a magazine which is composed of two parts: one constituting the mechanism of retraction, and the other the cartridge or tank of plates, which can be completely separated. This disposal makes it possible to have several of these cartridges charged with plates, so that one can make the loading and the unloading of the jumelle camera in full daylight; they are completely closed by parts whom one removes only after having insert them into the magazine; their price is relatively low, since they do not include any mechanism.
The shutter of the jumelle camera is provided with a regulator with a shape of a butterfly, similar to that of clockworks, which make the functioning at the various speeds sure and regular.
Off-centring is done in the two directions, but instead of being obtained, like most of the time, by the displacement of the small plank of lens, it is put back towards the back of the part which forms darkroom more or less at the junction point of this one with the magazine. It is actually this one which moves either to the bottom, or on the right and on the left. This disposal was adopted to allow the use of a viewfinder calculated so that it gives exactly the same picture, half reduced, that which produced on the sensitive plate; one needs for that which the lens forming the viewfinder has even focal distance that the used lens, so the eyepiece which is used for the centring is mounted on a slide fixed at the back of the magazine. This slide is pulled, and one obtains the focal distance necessary.

As a whole, this jumelle camera is very complete and is very well studied, it is an precision instrument which has very appreciable advantages to the point of view of the loading and centring, as well as from the point of view of the functioning, as well of the retraction as of the shutter.
