Kingdom of Prussia and Empire of Germany, Engineer and Patent Solicitor.
"IMPROVEMENTS IN PAPER BLOCKS FOR CALENDARS AND FOR OTHER PURPOSES, AND
IN THE METHOD OF MOUNTING THE SAME." A communication from Heinrich Georg
Wilhelm Ebbardt, Eduard Wilhelm Heinrich Nölke, and Heinrich Meineke,
Manufacturers, all of Hanover, in the said Kingdom of Prussia.
The Invention relates to that kind of paper blocks which are composed of a
number of separate paper leaves made into a pile, to three sides of which is pasted
a strip of paper; or they are otherwise connected, so as to unite all the leaves into
one solid block.
The leaves themselves may be blank, to write on, or printed, as in calendar
blocks, or partly printed and partly blank, as in notice calendar blocks.
The object of this Invention is to make those blocks more handy, and to enlarge
the range of their use. In all the blocks hitherto made, as above mentioned, the
whole of the upper leaf is torn off to make use of the next one; but as the remaining
leaves are all united together on the three sides of the block it is impossible to
make any notice on a leaf which is not on the top of the pile.

page_text: In the improved blocks the pile of leaves is pasted together only on one end by
a very narrow strip of paper or cloth, or are otherwise connected, and fastened
down to a pasteboard or other back by means of wire, or string, or other suitable
ineans. Across the face of each leaf, and close to a narrow strip at the end, where
the leaves are connected together, a line of small holes is perforated, so that by
tearing a leaf it will be severed at this line, leaving entire that small part of the
block.
The blank face of every leaf up to the perforations may be utilized for making
notices at any time, so that memorandums or information of any character put
down in advance will appear in due time after the previous leaves are torn off.
To have a paper block fixed to a piece of pasteboard or the like lying on the table
or hanging on the wall is not a convenient position for writing notices. There-
fore, according to the present Invention, the block is fastened to a desk-shaped
foundation, of any convenient material, by means of glue or nails. But, after
having used up the block it is, according to this plan, troublesome to remove the
fastened pasteboard and to replace it by a new paper block.
According to the present Invention the following arrangement is devised to
facilitate this manipulation:-The foundation or base is provided on its top with
two lugs or projections serving as bearings for a pin which extends across the
foundation or base. On this pin turns a clamp, the longer vertical wing of it
forming an angle with the shorter one, which bears upon the narrow strip at the
connected part of the block, which rests on the inclined face of the base and against
a projecting lip at the lower part thereof. Round the pin a wire spring is coiled,
the ends of it being fastened in such a way to the lugs and the clamp that the
latter presses hard down upon the block. By lifting the clamp, the block, or the
remainder of it, becomes free, and may be replaced by a new block, or for inspec-
tion, or for making notices thereon, or for other purposes.
Although this construction is very convenient the following may be employed,
which serves two purposes at the same time:-The frame is formed with two side
standards, which are connected together at their upper ends by a pin or wire, on
which the block rests at its upper end, and on the base of the frame the free end of
the block finds a support. The last leaf of the block is pasted on a piece of paste
or mill board of the same dimensions, and fastened on the pin by means of a spring
clip, the two ends of which clasp the pin, and the middle part bears upon the
narrow strip at the connected end of the block. This position is the most con-
venient to look at, but for writing upon the notice block its position for con-
venience should be altered. For this purpose the block is to be raised by its free
end as high as convenient, and supported in this position by laying a pencil, a
penholder, or similar object below it across the frame into corresponding recesses
formed in the side standards, or by projections therefrom, so that the most suitable
inclination of the block may be attained.
It is not essential for the present Invention to use a spring as the means of
fastening detachably the block to the pin, but any device will do which will allow
quick disengaging of the block and at the same time a swinging motion thereof.
If desired, the following arrangement may be employed: A clamping frame
swinging by its trunnions in the frame holds the block, which is fastened into it by
a thumbscrew. But other devices may be readily substituted, provided they fulfil
the above-mentioned requirements.
It must be understood that the described devices for supporting a paper block
can be also used as parts of writing desks, writing cases, letter cases, and other
articles.

"IMPROVEMENTS IN PAPER BLOCKS FOR CALENDARS AND FOR OTHER PURPOSES, AND
IN THE METHOD OF MOUNTING THE SAME." A communication by Heinrich Georg
Wilhelm Ebhardt, Eduard Wilhelm Heinrich Nölke, and Heinrich Meineke, Manu-
facturers, all of Hanover, in the said Kingdom of Prussia.

The Invention relates to that kind of paper blocks which are composed of a
number of separate paper leaves made in a pile, to three sides of which is pasted a
strip of paper; or they are otherwise connected, so as to unite all the leaves into
one solid block.
The leaves themselves may be blank to write on, or printed, as in calendar
blocks, or partly printed and partly blank, as in notice calendar blocks.
The object of this Invention is to make those blocks more handy, and to enlarge
the range of their use.
In all the blocks hitherto made, as above mentioned, the whole of the upper leaf:
is torn off to make use of the next one, but as the remaining leaves are all united
together on the three sides of the block it is impossible to make any notice on a
leaf which is not on the top of the pile.

means. Across the face of each leaf, and close to a narrow strip at the end.where
the leaves are connected together, a line of small holes is perforated, so that by:
tearing a leaf it will be severed at this line, leaving entire the small part D of the
block.

notices at any time, so that memorandums or information of any character put.
down in advance will appear in due time after the previous leaves are torn off.
To have a paper block fixed to a piece of pasteboard, or the like, lying on the
table or hanging on the wall is not a convenient position for writing notices.
Therefore according to the present Invention the block B is fastened to a desk-
shaped foundation A, Figure 3, of any convenient material by means of glue .or.
nails. But after having used up the block B it is, according to this plan, trouble-
some to remove the fastened pasteboard and to replace it by a new paper block.
At Figures 4 and 5 a device is represented to facilitate this manipulation. A is
the foundation or base, which is provided on its top with two lugs.or projections H,:
serving as bearings for a pin C, which extends across the foundation or base A. On:
this pin C turns a clamp K, the longer vertical wing of it forming an angle .with
i

page_text: the shorter one, which bears upon the narrow strip at the connected part D of the
block B, which rests on the inclined face of the base A and against a projecting
lip L at the lower part thereof. Round the pin C a wire spring is coiled, the ends
of it being fastened in such a way to the lugs H and the clamp K that the latter
presses hard down upon the block B. By lifting the clamp K the block B, or the 5
remainder of it, becomes free, and may be replaced by a new block or for inspection,
or for making notices thereon, or for other purposes.
Although this construction is very convenient the following may be employed,
which is ornamental and serves two purposes at the same time:-Figures 6 and 7
represent two views thereof. A is a frame, which is formed with two side 1
standards connected together at their upper ends by a pin or wire C, on which the
block B swings at its upper end, and on the base of the frame the free end of the
block B finds a support. The last leaf of the block B is pasted on a piece of paste-
board or millboard of the same dimensions, and fastened on the pin C by means of
a spring clip F, the two ends of which clasp the pin C, and the middle part bears
upon the part D of the block B. This position, which is represented in the
Drawing, is the most convenient to look at, but for writing upon the notice block its
position for convenience should be altered. For this purpose the block B is to be
raised by its. free end as high as convenient, and supported in this position by
laying a pencil, a penholder, or similar object, below it across the frame into cor- 2
responding recesses formed in the side standards, or by projections E, E, of the
frame A, so that the most suitable inclination of the block B may be attained.
It. is not essential for the present Invention to use a spring as the means of
fastening detachably the block B to the pin C, but any device will do which will
allow a quick disengaging of the block B, and at the same time a swinging motion 2
thereof. Figures 8 and 9 show such an arrangement.
A clamping frame G swinging by its trunnions C in the frame A holds the
block B, which is fastened into it by a thumbscrew P. But other devices may be
readily substituted, provided they fulfil the above-mentioned requirements.
It must be understood that the described devices for supporting a paper block 3
can be also used as parts of writing desks, writing cases, letter cases, and other
articles.
Having thus described the nature of the said Invention, and the mode in which
the same is carried into effect, I would have it understood that what I claim as
new and wish to secure by Letters Patent is,―
First. A paper block composed of single leaves, which may be blank, printed, or
partly printed and partly blank, and which are only united at one end by a narrow
strip of paper or other material, and fastened to a suitable base by paste, or by a
wire or string surrounding that narrow strip, substantially as shown and described,
and for the purpose set forth.
Second. For paper blocks composed of single leaves a foundation with one
inclined surface, to which the block is rigidly fastened by any suitable device, or
detachably by means of a spring, clamp, screw, or their equivalent, substantially as
shown and described.

Third. The arrangement of a paper block swinging on or between a supporting 4
frame for the purpose specified, and substantially as shown and described.
Fourth. A paper block, which is fastened detachably to a pin in a clamping
frame by means of springs, screws, or substitutes therefor, when the block swings
round an axis, substantially as shown and described.
Fifth. Fastening a paper block rigidly to its base or support by means of a wire,'
string, or other means, substantially as shown and described.
Sixth. Fastening a paper block detachably to its base or support by means of
springs, screws, or their equivalents, if the block does not swing on or between the
support or base, substantially as shown and described.
.. Seventh, A frame supporting a stationary or swinging paper block, as shown a

page_text: and described, if used alone or as part of a writing case, or of other writing
utensil.
In witness whereof, I, the said Carl Theodor Burchardt, have hereunto set
my hand and seal, this Twenty-fourth day of February, in the year of our
Lord One thousand eight hundred and seventy-nine.
