Improvements in Paper Files.
I, OTTO SKREBBA, of 13, Erwinstrasse, Freiburg, Baden, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved device for fastening the letters or
documents in paper files, the same being distinguished from known devices of
this kind in as much as the opening of the clasps is effected by the aid of cranked
levers partly located in a flat bodied casing acted upon by the said levers, and
by the fact that the said clasps are retained in their open position by the action
of the cranked lever or levers.
A constructional form of this fastening device is shewn in the accompanying
drawing, in which,
Fig. represents a perspective view.
Figs. 2 and 3 are side elevations, and,
Figs. 4 and 5 illustrate the device with the curved pieces or clasps in open
position.
The fastening device is applicable to 'files mounted on a wooden base as well
as to book shaped files, and consists of the known curved pieces or clasps divided
longitudinally at a suitable place, and serving to receive the documents and
the like slid over the said clasps. The clasps thus each consist of the parts a
and a', the former of which (a) serve for receiving the documents pinned on to
them; these parts a being fixed to a plate b. The parts a¹ of the two clasps
appertaining to one fastening device are usually made of one piece which is
pivotally secured to the plate at c. To the part of the clasps bearing against
the plate ba flat casing d is fixed, the free extremity of which bears against the
plate when the clasps are in the closed position. In this closed position the
clasps are held by means of the casing d through the action of a spring e fixed
to the casing d and to the plate . In the hollow interior of the flat casing
a lug f is arranged, the same being mounted on the plate b. On this lug the

has its pivotted end so bent at h that the bent part or knee h of the lever g
causes the casing d to be lifted and turned in the direction indicated by the
arrow, Fig. 1. By this turning motion, seeing that d is rigidly connected with a',
the clasps a are of course likewise turned in the direction indicated by the
arrows m. Owing to the arrangement of the cranked lever it is possible to retain
the movable parts a' of the clasps in their open position. The free ends of the
clasp portions a are pointed so as to facilitate the operation of pinning the docu-
ments on to them, and in general to ensure a smooth fitting of the parts a a¹ at
this place.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to he performed, I declare that what
I claim is:-

actuated casing (d) as well as the movable parts (a) of the clasps so as to effect
the opening of the device in the direction indicated by the arrows m, the said
cranked levers serving also to retain the clasps in their open position.
