Improvements in the Manufacture of Cases for Holding Instruments
and other Objects.
I, CARL MORITZ, of 15, Gipsstr., Berlin, C., in the German Empire,
Instrument-maker to the German Imperial Court, 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 :-
This invention relates to the manufacture of cases of paste-board, in particular
such which are of irregular or partly irregular shape, for instance cases for music
instruments of any kind. Heretofore such cases have been generally made of wood,
as the same are sometimes required to resist great pressure, to protect the instrument
in transit from injury.
The said construction of cases is a very expensive one, in particular, if they are
of irregular or partly irregular shape, as for instance violin cases, the cost of the
violin in itself being already a consideration.
This invention has for its object to obviate these defects, and produce the said
cases of paste-board in such a manner, that in spite of the nature of the latter the
cases will have sufficient power of resistance.
For this purpose paper, wadding and moist paste-board are divided in pieces of
any desired size and shape, and are put completely irregularly into a mould, the
interior of which corresponds with the part of the case to be produced. Several
layers are formed in the said mould, and the parts forming a layer are fastened
together by means of a suitable binding substance; the joints between the parts of
one layer are preferably displaced relative to those of the other layers, whereby
the several layers will also become fastened together themselves through the
binding substance.
I prefer to use but thin paste-board as the same is better adapted to conform with
any curve, bending or other irregularity in the shape of the mould. The pressing
of the paper, wadding and paste-board pieces takes place by hand without the aid
of any appliance, no special pressure being exerted on the pieces and layers in the
mould whilst drying. When this substance is dry it represents a solid piece of great
durability and forms in connection with the binding substance a case which when
used for the purposes described will successfully compete with cases made of wood.
The cases being generally formed in two parts, it is necessary to hinge the same
together. A closing device is also necessary. In order to connect these parts
securely to the case, which, of course, will have to be done by screws, it is preferred
to insert into the mass pieces of wood at the respective parts. This is done
advantageously by placing such picces of wood in their respective positions onto one
or two of the layers in the mould, and fastening the same thereto by pressing
in the remainder layer or layers, so that the said pieces of wood are secured between
two or more such paper, wadding and paste-board layers.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The method of manufacturing cases, capable of resisting pressure, for holding
instruments, consisting in pressing pieces or strips of paper, wadding and paste-
board in several layers into the interior of a mould, which in shape corresponds
with that of the case-part to be produced, and fastening the same together by
a suitable cementing-medium, substantially as set forth.
2. The method of manufacturing cases as specified in the preceding claim, in
which the regular or irregular-shaped pieces of paper, wadding and paste-board are

page_text: placed into the mould and are connected therein in such a manner, that the joints
in each layer are displaced relative to those of the adjacent layers, substantially as
and for the purpose set forth.
3. The method of manufacturing cases as specified in Claim 1, in which the
pieces of paper, wadding and paste-board, besides serving for the formation of the
case itself, are also used for securing pieces of wood or the like, in such position
where it is desired to fix locks, hinges and the like mountings, substantially as and
for the purpose set forth.
