“ The main object of the invention consists in a construction whereby the shutters are opened and closed by the outward stroke or movement only of the piston-rod of the engine, or whatever the operating means is, and remain in said position, while the operating mechanism assumes its normal position, ready for another operation. ”

“ In a photographic shutter, the combination of the centrally-pivoted double lever having the end projections and the projections each side of its pivot, the pivoted lever-plate, the pivoted dog connecting with a projection of said lever-plate and with the projection which is on the double lever, said lever-plate being also provided with an extension adapted to engage one of the side projections of said double lever during the lateral swing of the lever-plate, and the slides or shutters forming a cam engagement with the end projections of the double lever, substantially as set forth. ”
