I, THOMAS GEORG HARIG, of 4 Windmühlstrasse, Frankfort on the Main, in
the Empire of Germany, 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 :-
The subject of the present invention relates to book supports which can be
placed in such a position that the upper portion can be used to support the thin
side of a thick open book while the arm rest can be adjusted simultaneously in
such a way as to support the hand or the arm firmly on a level with the page to be
written on.
In every large business house there are large or voluminous ledgers account
current books &c. &c. in which it is difficult to make entries on the thin side.
which lies obliquely when open and also to write on the bottom part of the page
owing to the absence of adjustable supports for the oblique portion of the hook
and for the hand or arm.
The subject of the present invention which is represented in the accompanying
drawing obviates these difficulties.

Fig. 2. Transverse section of the same book support on line y-y Fig. 1.
Fig. 3. Longitudinal section of an arm rest on line - Fig. 4.
Fig. 4. Transverse section of the same arm rest on line - Fig. 3.
The appliance consists of a wooden slab a sufficiently large for the purpose on
to which two angle irons c c each with two slits are screwed at the sides..
Opposite these two irons there are two others d d which lie ou the desk and
which in this shape are of equal length to the upper angle irons cc for both
supports.
In the arm rest however in Fig. 3 the lower angle irons are lengthened and the
upright part cut off so that on each side a flat iron surface e e is formed as a
continuation of the lower angle iron d d.
Between the upper and the lower angle irons two flat cross stays of iron ƒƒ
are fitted which at the point of intersection are provided with sits 99 through
which a bolt h with a nut is passed which holds the two pieces of iron firmly
together. At the lower end these flat pieces of iron are pivoted to the lower
angle irons d d by means of pins ii and they slide along the upper angle irons c c
by means of pins k k in the slits b b.
By means of this arrangement the wooden slab a a can be fixed at any height
that may be desired corresponding to the thickness of the book, on the lower part
of a page of which the user wishes to write or by pushing the book support
under the obliquely lying portion of an open book the latter can be written on
with the same ease as the side which lies horizontally.
The lengthened parts of the lower angle irons d d of the arm rest Fig. 3.
forming the flat pieces of iron ee are pushed in use underneath the book thus
giving the arm rest a firm position. This must be done when the user desires to
write on the lower portion of the thicker side of the book.
On the other hand should it be desired to make an entry on the lower part of a
page on the oblique side the book support as in Fig. 1 is placed underneath
and the arm rest with the flat pieces of iron e e are pushed under the angle
irons d d of the book support by means of which the former is again held firmly
in position.

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 :-
A book and arm rest constructed with two upper angle irons cc and two lower
angle irons d d the two angle irons c and d lying one over the other and connected
by two flat crossed pieces of iron ff in combination with a wooden slab a
fastened on the upper angle irons so arranged that the slab a can be adjusted and
fixed at any required height by means of horizontal slits bb in the angle irons c c
and diagonal slits g g in the flat stays ff provided with a fastening bolt or pin f
with or without the flat extensions e of the lower augle irons substantially as and
for the purpose described.
