Improvements in or relating to Adjustable Shelves for Book Cases
and other Articles.
We, HERMANN SCHULZ, EMIL STRUBEL and FERDINAND IDLER, all of
10 Zossenerstrasse Berlin in the Empire of Germany, Manufacturers, do hereby
declare the nature of our invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
The improvements in adjustable shelves for bookcases and other articles consist
in a more simplified form of construction to avoid all outwardly extending pro-
trusions from the inner sides and to keep the latter flat or plane so as to facilitate
the removal of books or other objects therefrom especially those placed close to the
sides without having to disturb others.
The improved construction according to the present invention renders the
adjustment of the shelves easier and more simple while at the same time it ensures
greater stability and strength to the furniture.
The invention is illustrated in the accompanying drawings in which
Figure 1 shows the general arrangement of constructing adjustable shelves
according to the invention.
Figure 2 is an end view of the shelf shown in perspective.
Figure 3 is a view on an enlarged scale of part of the inner side of a piece of
furniture showing the supports for the shelves.
In carrying our invention into practice, we first form two grooves a b in each of
the inner sides of the article of furniture, the groove a being near the front and the
groove b near the back as shown in Figure 1. the depth of these grooves being such
as to suit the length of the pins c fixed at both ends of the shelves in the manner
illustrated in Figure 2.
Two suitable strips d of hard wood and provided with saw cuts e in the form of
a rack, as shown at Figure 3 to suit the form of the pins c, are then fixed in the
grooves a and b.
The shelf or shelves are placed with their pins c at each end into the corre-
sponding teeth e of the rack d at any desired height and when it is desired to
adjust the shelves to a different height, they are slightly raised and pulled forward
so as to release the pins c from the rack teeth e when the pins c can travel either up
or down in the groove b to the desired position when by pushing the shelf back the
pins c will be caused to rest in the desired teeth e.
Having now particularly described and ascertained the nature of our' said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An adjustable shelf for bookcases and other articles provided at both ends
with pins c which are inserted into the teeth of racks fixed in suitable grooves
provided for the purpose in the sides of the furniture substantially as herein shown
and described

page_text: 2. The improvements in or relating to adjustable shelves for bookcases and
other articles substantially as herein shown and described and for the purpose
stated.
