Abstract
347,948. Loose-leaf binders. POL REGISTRATOR CIE, 197, Fischelnerstrasse, Krefeld, Germany. June 19, 1930, No. 18755. Convention date, June 28, 1929. [Class 146 (i).] In loose-leaf binders comprising opposed sets of prongs d<1>, d<2> of which one set d<1> is freely pivoted on a baseplate b and the other set d<2> is controlled by a spring f tending to close the prongs, the set d<2> is moved to open position by a lever and retained in such position by a catch. The pivot rods el, e<2> of the prongs are formed with cranked parts n, o respectively which overlap in the closed position of the file with the part n underneath and are retained in such position by the spring f coiled on the rod e2. In order to open the file, a lever s having its nose engaging beneath the part o is depressed and lifts the part o. A pivoted catch p moves into position beneath the part o under the action of a spring k to hold the prongs d<2> in the open position. After the lever s has been moved a certain distance, a stop w thereon engages a subsidiary lever v adapted to operate on the part n and move the prongs d<1> farther away from the prongs d<2>. To close the file, the prongs d<1> are moved back to their normal position and the part n engages a sloping part p<1> on the catch p so as to force the catch back and allow the loop o and prongs d<2> to return to normal position under the action of the spring f.
