page_text: I, HENRIETTE AUGUSTE MARIE DITTMAR, of the firm of A. Dittmar, of Berlin, in
the Empire of Germany, Album Manufacturer, 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:-
My invention relates to photograph-albums.
In photograph-albums as heretofore manufactured the photographs are generally
fixed by inserting them through slits in the cardboard leaves below the spaces designed
for the photographs as shown in Figure 1 of the drawings hereinafter referred to.
In some photograph-albums, especially those in which each side of the leaf is
designed for only one photograph, the photographs are inserted through a slit made
in the edge of the leaf, which slit communicates with the free space left for the photo-
graphs when the several thicknesses of cardboard of which the leaf is composed are
pasted together.
In the construction first referred to the ornamented cover paper of the leaf is
frequently torn and injured this construction is moreover inconvenient and nessitates
some skill to insert, displace, or remove the photographs.
According to the present invention cach leaf is made in two parts so that to insert a
photograph it is only necessary to separate the two halves or paris from each other, to
lay the photograph in the place designed for it, and to again close the two parts of
the leaf against each other.
In the accompanying drawings:-
Figure 1 is a front view of a leaf of a photograph album provided with slits in the
known manner for introducing the photographs.
Figure 2 a photograph-album leaf consisting of two parts arranged according to my
invention.
Figure 3 is a view similar to Figure 2, but illustrating a modification of the said
invention.
Figure 4 is a section on the line A, B, Figure 3.

together.
Figure 7 is an edge view of the leaf with the two parts together.
Figure 8 is a section on the line E F, Figure 3.
Figure 9 is a section on the line G, HÍ, Figure 3.
Figures 10, 11, 12, 13 and 14 are views illustrating modifications of the construction
represented in Figures 2 to 7.
The part of the leave represented at the left of Figure 2 consists of a cardboard
sheet which contains openings that serve, as it were, as frames for the photographs.
Upon the back-side of the cardboard (that is to say upon the one represented in the
drawing) is pasted or glued around its edge a strong pasteboard rib a².
The other cardboard sheet d, forming the second half of the album leaf has also
openings as above described, and is designed for the reception of, or as a frame for,
four photographs. Upon the back or inner side of the same is likewise pasted a strong
pasteboard rib. The latter forms the counterpart in all respects of the rib a', so that
the inner edges of the rib a', fit firmly against the outer edges of the rib d' when the two
parts of the leaf are placed together. The inner and outer edges of the ribs a¹, d' are
cut in such a manner that although sliding past each other, they notwithstanding
firmly adhere after they are placed together, but only to such a degree that they can
be separated from each other by a moderate pull with the fingers.
In the modification represented in Figure 3 the inner edge of the rib a is provided
with projections whilst the opposite rib d¹ is provided with corresponding notches or
recesses c, in which, when the two leaf parts are placed together, the projections are
located so as to hold. The two leaf parts, in order to lay them together are connected
behind by a leather or linen strip which serves as a hinge.
Upon the stronger pasteboard frame at the right hand side of Figure 3 (or of the
left hand) is pasted a sheet of paper by means of linen or the like so that the linen
acts as a hinge at g,
At suitable points h h strips of linen or the like are pasted upon this sheet of paper
in such a manner as to form the pockets kk for the reception of the photographs 17.
As shown in Figures 4 and 5 the use of the pockets is provided for on both sides of
the sheet of paper, accordingly eight pockets are formed which are designed for the
reception of eight photographs for the eight openings m m.
In the modification of my invention represented in figure 10 (and in figure 15 where
the leaf is represented as being open) the pasteboard ribs secured on the two sheets
of cardboard a and d are placed at alternating points on the opposite sheets and
atlapted to engage with each other.
In the construction represented in figure 11 (and in an open position in figure 17)
the cardboard sheets a and d are provided with pasteboard ribs of uniform thickness
and with lugs or projections on the near sides, which mutually engage with each other.
In this arrangement the joint would be in the middle of the thickness of the album leaf.
Figures 12 and 16 show an arrangement wherein the strong pasteboard ribs a dare
provided with suitable furrows or grooves n, n' which are filled with material that does
not harden but sticks (as for example a composition of gelatine, glycerine, and glue),
which, when the two leaf parts are turned back to back against each other adheres
and thus holds the two parts together, but which can also be separated or opened again
without trouble, according to the adhesiveness of the material employed.
In figures 13 and 18 the union of the two parts of the leaf is effected by headed
fasteners oo which are arranged upon one of the pasteboard frames or ribs a² and
on the leaf parts being pressed together enter openings provided on the opposite
frame. The said openings are a little smaller than the heads o', so that the latter
when pressed into the said openings bear firmly against their walls and are unable
to leave them voluntarily.
On the pasteboard strips represented in Figure 14 projecting parts ? pare
arranged, which, when the two parts are pressed together, slide over each other, one
bearing against another and holding the two parts together.

page_text: Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
First. In a photographic album the employment of leaves each of which is formed
in two parts adapted to be fitted together and separated for the purpose specified.
Second. In a leaf of the class described in the preceding claiming clause tho
employment of frames or ribs pasted or otherwise secured on the inner sides of the
respective parts, which ribs can be plain or provided with lugs or depressions as
desired and which fit exactly one into the other so that by pressing the two parts
together they will be firmly united, substantially as described with reference to
Figures 2, 3, 4, 5, 6 and 7 of the drawings.
Third. The employment of lugs or projections secured at alternating points upon
the opposite parts and engaging with each other substantially as described-with
reference to Figures 10 and 15 of the drawings.
Fourth. The employment of frames or ribs having corresponding recesses and
projections substantially as described with reference to Figures 11 and 17 of the
drawings.
Fifth. The employment of frames or ribs having grooves or depressions which
receive an adhesive substance and by means of which, on the leaf ports being pressed
together, the latter continue to adhere substantially as described with reference to
Figures 12 and 16 of the drawings.
Sixth. The application of headed fasteners led into one frame and with the heads
fitting closely within corresponding depressions in the opposite frame and thus holding
the parts together substantially as described with reference to Figures 13 and 18 of
the drawings.
Seventh. The employment of pasteboard frames, each having a projecting rib and
groove which fit into one another when the parts are pressed together substantially
as described with reference to Figure 14 of the drawings.
