COMPLETE SPECIFICATION.
Improvements relating to Portfolios or Files for Papers and
other objects, and to Perforators for use in connection
therewith.
i
I, OSWALD ASSMANN, Engineer, of Tegelen, in the Kingdom of the Nether-
lands, 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 consists principally in improvements applied to portfolios or files,
serving for keeping and registering letters, documents, newspapers or written and
printed papers, circulars, samples of merchandise or other objects; the improved
file being so constructed, that the letters or the like may be put in or taken out at
any desired place without disturbing the order of other papers or the like above
or below.
The invention also relates to perforators for punching holes in the papers or
the like for reception of the pins of the file. Reference being made to the
annexed drawings.
This improved file is shown in different positions in Figs. 1, 2 & 3, while
Figs. 4, 5 & 6 represent the essential mechanism on a larger scale for better and
clearer illustration.
Figs. 7, 8 & 9 show the perforator, belonging to the apparatus.
The file is composed of two halves H, connected by hinges, these halves being
provided each with a series of pins Z bent in such a manner, that on opening and
closing the covers, to which the halves II are respectively connected, these pins
move axially in parallel curves. The length of the pins Z is such, that the points'
of the each series project beyond the roots of the other series.
When in normal position, the cross bars attached to the covers, limit the move-
ment of the latter, while these covers, when open, are held in this position by
means of the spiral spring f.
On both halves H connected by hinges is first fixed the strong spring, the free
erds of which are connected to respective strips on the two halves so that the
spring itself forks over the hinge. This arrangement causes the spring f to be
double acting, that is to say this spring will tend to hold the file either fully closed
or fully open.
The hinge between the two halves must be so arranged, that it projects out at
the back of the portfolio. The mechanism itself is so riveted in the back of the
portfolio, that the axis of the hinge is in the plane of the back of the portfolio.
The mechanism is furthermore fixed down on the under or right hand cover by
means of a wire loop catching into a strip 7, suitably attached to the cover; this
connection however gives sufficient play, that the mechanism may be lifted up
from the cover do a distance of about the thickness of a finger, for the purpose of
enabling the hand to reach conveniently underneath the lowest papers on the file.
This connection may however be made to unhook, so that the portfolio may be
used equally conveniently from either side.
The perforator being a necessary adjunct of the aforesaid file, is shown in Fig. 7
in front elevation, in Fig. 8 in plan and Fig. 9 in side-view.
This perforator, is composed of a base plate A with its brackets cast thereon,
these laterally carry each a round cylindrical head, perforated in direction of their
length, these perforations being aligned with and of exactly the same diameter,
as those provided underneath these cylinder heads in the base plate. Between the
brackets and the base plate A a space is left, for insertion of the papers to be
punched.
The proper perforating stamps are fitted to slide in the cylindrical heads of the

page_text: brackets and their upper freo ends are movably fixed to the lever B by means of
small cross-pins. This lever B is connected by the pin d to the links D, the
latter connected to the supports a a¹ so as to oscillate thereon; the connection of
the strips D to the supports «
being likewise effected by a traversing pin d.
The upper part of each link D is provided with two properly formed noses, the
purpose of which is, to limit the movement of the lever B both upwards and
downwards.
"
Between the two traversing pins da plate 6 is provided, not only to prevent a
lateral displacing of the links D but also to serve at same time as an abutment for
the spring for lifting the lever B.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1.) In a portfolio or file for keeping, collecting and registering letters or other
flat objects, the combination with the two covers hinged together and provided
each with a series of bent pius of spring f, arranged to fork the hinge and retain
the covers either fully open or fully closed substantially as described.
2.) In the file or portfolio above described the loop of wire, fixed on the back of
the portfolio by strip and adapted to be unhooked for the purpose described.
a
3.) For use in combination with the file al perforator adapted to punch the
papers etc. to be filed at the points corresponding to the pins of the file
the said perforator comprising the base plate A with brackets
carrying
cylindrical punchers, operated by the lever B and connecting links D D adapted
to carry the lever B and to limit the strike of the lever by means of two
suitable noses.
4.) In the perforator described the traversing pins d d in combination with
the plate b, to hold the different parts of the perforator in relatively correct
position and to serve as abutment to the spring, operating to lift the lever Bas
described.
