MENTS OF PORTFOLIOS"
This Invention relates to combined pasteboard or cardboard portfolios and an
easel for diawings, engravings, &c, which is characterized by an arrangement for
unfolding the moveable fiont part of the said portfolio
On the moveable cover I arrange a truss or fiame held by hinges at the upper
pait This moveable truss or frame, which contributes to the ornamentation of the
portfolio, may be fixed to the cover near the lower part by two kinds of pivots.
In this state the truss or fiame extends a short distance beyond the portfolio, and
if the moveable cover be unfolded or let down the said tiuss rests itself on two
inclined parts of the uprights on standards of the easel, so that the portfolio keeps
itself half open, and the drawings or engraveings therein may be easily withdrawn
therefrom If on the contrary the truss or frame be free at its lower part and
detached from the cover this cover may be folded down horizontally, the truss or
frame turning on its hinges, and serving as supports to enable the contents to be
examined
My portfolio can be detached from the easel which holds it if one wishes to place
it on a table, it can however be solidly fitted on its easel by means of hooks
explained herein-after.
The portfolio is composed or formed of a back fixed to the easel, and furnished
at the side with two cheeks to protect the drawings or engravings This back is
attached by means of a bottom piece to a moveable cover at its upper part, it falls
over on the easel, and a lock unites the two parts
On the cover is arranged a moveable truss or frame composed of two bars united
by a cross piece or bai, the two bars being articulated at their upper part to the
cover by means of hinges, near which are interposed flat springs. The two bars are

My portfolio is fixed on its easel by means of two slotted hook plates, at the back
which engage over corresponding shaped studs fixed in the supports, standards
or upughts of the casel These hook plates carry inwardly in a direction with the
length of the slot a projection or swelling, so that when lowering the portfolio on
its easel the studs slide over the swelling and force the back of the said portfolio to
lay itself exactly on the easel
The square-headed keys present an arrangement which has for effect to bring
the key either in the duection of the bar or perpendicularly to this bar
The axle
of this key is fixed on a cun which has two stop notches arranged at 1ight angles
This cam is held in the inside of a plate cut in such way as to present two dia-
metrically opposite notches, so that the key may displace itself exactly at right
angles This plate is rivetted on the moveable cover of the portfolio

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Wilhelm Marx in the Great Seal Patent Office on the 4th August
1877
WILHELM MARX, of Paris (France), Manufacturer "IMPROVEMENTS IN ARRANGE-
MENTS OF PORTFOLIOS"
This Invention relates to a combined pasteboard or cardboard portfolio and easel
for drawings, engravings, etc, which is characterized by an arrangement for unfolding
the moveable fiont part of the said portfolio
On the moveable cover I arrange a truss or flame held by hinges at the upper
part This moveable truss or fiame, which contributes to the ornamentation of the
portfolio, may be fixed to the cover near the lower part by two kinds of pivots. In
this condition the truss or fiame extends a short distance beyond the portfolio, and
if the moveable cover be unfolded or let down the said truss or frame rests upon or
is supported by two inclined parts of the upughts or standards of the casel, so that
the portfolio is kept half open, thus facilitating the withdrawal of the drawings or
engravings enclosed therein
If on the contrary the truss or fiame be free at its
lower pait and detached from the cover this cover may be folded down horizontally
The truss or frame turning on its hinges serves as a support and enables the contents
of the portfolio to be examined
My portfolio can be detached with the greatest facility from the easel which
'holds it if it be desired to place it upon a table, it is nevertheless firmly fitted to
its easel by means of hooks of special construction, as her ein-after described
The Invention will be cleaily understood by the following description and
reference to the annexed Diawings, in which Figure 1 is a side view of the port-
folio mounted upon its easel, and Figure 2 is a front view of the same
The portfolio is composed of a back or base a fixed to the easel, and furnished at
the side with two cheeks b to protect the diawings or engravings This back is
'attached by means of a bottom piece c to a moveable cover d At its upper part it
falls over on the easel and a lock unites the two paits
On the cover d is aanged a movable truss or frame composed of two bars f, f
united by a cross piece or bar g, the two bars being articulated at their upper part

page_text: to the cover d by means of hinges o, o, near which are interposed flat springs l, l.
The two bars are fixed to the lower part of this same cover by means of two square
headed buttons or keys h The easel C which supports the portfolio does not
present any other peculiarity than the arrangement upon the uprights or standards
of the two inclined brackets k, k If the portfolio be opened then as the bars f, f.
are fixed to then base by the keys h the moveable cover d occupies the position
shown in Figure 1, the truss or frame resting on the inclined brackets k, k If
the truss or fiame be detached from the moveable part of the portfolio the little
springs 1, 1, near the hinges o, o, (see Figure 7) raise this truss or frame a little.
When the portfolio is opened under these conditions the said truss or frame takes
a vertical position and acts as a foot which holds the cover, as shown in dotted
lines in Figure 1 of the accompanying Diawings
My portfolio is fixed on its easel by means of two slotted hook plates m, m,
shown separately on a larger scale in Figures 3 and 4 Upon the back of the port-
folio are fixed the hooks m, m, which take over correspondingly shaped studs n, n,
fixed in the standards or uprights of the casel These hook plates carry in the
interior lengthways of the groove an enlargement or swelling p (see Figures 3 and 4),
so that when lowering the portfolio on its easel the studs n sliding upon the
enlargements p force the back of the said portfolio to lie exactly on the casel.
The square-headed keys h, h, prosent a special arrangement, represented at
Figures 5 and 6, the effect of which is to lead the key h either in the direction of
the bar for perpendicularly to this bar The axle of the key is fixed upon a cam q,
which has two stop notches arranged at right angles This cam is maintained in
the interior of a plate r so cut that the two notches are diametrically opposed in
order that the key may displace itself exactly at right angles. This plate ris
rivetted on the moveable cover & of the portfolio
My portfolio is also furnished with an appendage which can be adapted in both
positions of the cover, that is to say, either half open or completely shut This
appendage consists of a magnifying glass carried by a support arranged upon the
moveable cover, enabling the pictures, diawings, or engravings contained in the
portfolio to be viewed in a magnified condition This magnifying glass L is held
between two studs 2 upon a ring, arranged upon the bar or 1od k¹ This bar
or 1od may be inclined either forwards or backwards, as necessary, according to the
position of the covering The inclination takes place round the axle o¹ situated at
the upper part of the 1od m³, which fits into a groove n¹ or into another n² of a
metal piece p¹ of the moveable cover The openings q¹ and q³ with which the rod m¹
is pierced seive to receive the pins or pegs r₁ or which fix this rod at the desired
height
The upper bar or rod k¹ which carries the glass is held by stops & and s². This
bar is furnished with a slot or groove t upon its length, which allows the ring or
hoop which carries the magnifying glass to slide so as to vary the distance of the
glass from the picture, photograph, or view, according to the sight of the person
using it
When the magnifying glass is placed upon the cover completely closed, see
Figure 2, the photographs or drawings placed in the portfolio at P may be then
viewed by a person while seated
When one desires to remain standing to examine the photographs, drawings, or
engravings, the cover is left half open, and the magnifying glass is adapted as shown
in dotted lines, Figure 1, and the photographs are placed in P¹ upon a small desk
formed of two plates u arranged in lozenge shape jointed to the upper bar u', and
at bottom to a horizontal sheath or casing e¹, in which this lozenge fits or takes
when the portfolio is closed. The blades or plates u of the lozenge-shaped piece are
fastened at then lower ends by flat bolts x, so that without extracting these it is
impossible to open or close the lozenge-shaped desk The photographs P¹ rest
upon the little plates y with double hinges which rest upon the case or sheath e¹
Having now described the nature of my said Invention and in what manner the

page_text: same is to be performed, I declare that I claim as my herein-before described In-
vention of a combined portfolio and easel,―
Firstly The arrangement upon the moveable cover of a truss or frame jointed at
its upper pait, and capable of being fixed or detached at its lower part, so that the
said portfolio may be half open, and so that the moveable cover is supported by tho
frame or truss forming a foot, when the portfolio is completely opened, as described
and as shown in the accompanying Diawings
Secondly The special method of hooking or attaching the portfolio to its casel,
enabling the portfolio to be detached at will and placed upon a table, as described
and as shown on the accompanying Drawings
Thirdly. The employment, as described and shown, of square headed keys to
fasten the truss or frame to the moveable cover.
Fourthly The arrangement, as described and shown, of springs under the truss
or frame near its hinges
Fifthly, The employment, when desued, of a magnifying glass adapted to the
moveable cover, with the view of permitting the examination in a magnified con-
dition of photographs, drawings, oi engravings, either while leaving them in the
portfolio itself or placing them upon a jointed lozenge shaped desk, which opens out
above the portfolio, as described and shown in the annexed Drawings
In witness whereof, I, the said Wilhelm Marx, have hereunto set my hand and
seal, this Thirty-first day of July, One thousand eight hundred and seventy-
