I, HEINRICH GÜNDEL, of 46 Kohlgartenstrasse, Leipzig-Reudnitz, Germany,
Furniture Maker, 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:―
All school seats which are made adjustable so as to render it possible to employ
the same seats for scholars of different heights, are furnished with more or less
complicated mechanism, which is liable to wear and tear, and only allows of the
raising of the desk by taking hold of both ends of the top at the same time. The
top is in this case raised or lowered by means of joints or racks According to
this invention all complex mechanism is avoided. For this purpose, the side
cheeks of the top or desk board are guided at both ends by means of a pair of
quadrant shaped pin guides-(a pair of pin guides or the like in grooves rising
backwards in the side cheeks of the top).
Figure 1 is a side elevation of the arrangement, Figure 2 being a longitudinal
section of the same. Figure 3 is a sectional view, the top or desk portion being
removed.
The arrangement illustrated, consists of the two standards G and H, supported
apart by means of a cross-stay and the foot rest I. The top or desk A carries on its
ends cheeks E and F, and the book shelf U, which can be shut or closed in by
the back B.
The top A is not attached directly to the standards G and H, but rests with the
four pins VW and XY in the grooves QR and ST. The pins VW and XY,
if made of iron can be fixed to an iron plate, thus V W to an iron plate M, and X Y
to a plate N. Likewise also the grooves QR and ST can be cut in an iron plate,
thus the grooves QR are cut in the plate 0 and the grooves S T in the
plate P. This arrangement of two pins and two grooves in one plate is advisable
as their position in relation to one another should be unaltered. The grooves QR
and ST should ascend towards the back of the desk; they may be arched, straight,
or bent.
In order that a position of rest for the pins may be provided at the
upper end of the grooves the latter can be made to descend somewhat at this
point, so that the pins will not slide backward or down in the grooves, of them-
selves.
If the top or desk A is connected in this way with the standards G and H by
means of the pins VW and XY a slight raising of the desk suffices to bring it
into the higher position A¹ and at the same time the back B with the bookshelf
into the position B'. The raising can also be effected by the persons seated
on seat or bench L pressing with his knees against the underside of the bookshelf.
The top or desk A, however, is not only raised with the bookshelf but also
moved backwards, so that the taller scholar who is to make use of the raised
desk has more space i.e. greater freedom between the seat L and the top of the
desk A. If the grooves QR and ST are made to fall back or descend in the end

page_text: position at the upper end as illustrated, the top of the desk remains secured in
the upper position.
If a special foot-board be provided for smaller scholars, it is only necessary
to make this adjustable, as shewn in Figure 1, and bring it into the position K'
in order to allow for the longer legs of the taller scholars.
For this purpose, the foot-board K can run in grooves of the under frame.
In the form illustrated, side cheeks C 1) are attached to the outer ends of the
top part or desk. These form a side covering when the latter is in the higher
position. The pins VW and XY may also be attached to these outside cheeks.
In such case the latter must be broader; the inner cheeks EF might, however,
be dispensed with.
The arrangement may also be such that the pins VW and XY are attached
to the standards GH and the grooves QR and ST formed in the cheeks of the
top part A.
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:-
(1). A school seat with adjustable desk, which allows of the top part A being
adjusted horizontally and vertically, the distinguishing feature being that the
top part A is furnished at both ends with two pins VW and XY, and the
standards G H each with two grooves QR and ST which run upwards and back-
wards, in order to make the school seat adaptable for scholars of various heights.
(2). A form of the school seat according to Claim 1 the distinguishing feature
being that the grooves QR and ST are formed so as to descend or drop back at
the upper end for the purpose of securing the top part A in the raised position
without any fixing arrangement.
(3). A form of the school seat according to Claims 1 and 2 the distinguishing
feature being that a foot-board K is movably arranged on the lower frame of the
seat so as to be pushed back, as soon as a taller scholar requires the seat.
