Improvements in Organs and like Musical Instruments.
I, FRIEDRICH ERNST PAUL EHRLICH, Director of the Fabrik Leipziger Musik-
werke, vorm. Paul Ehrlich & Co., of Gohlis, near Leipzig, in the Kingdom of
Saxony, in the Empire of Germany, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The nature of my invention consists in a mechanism for transmitting the
movement of the key of an organ or like musical instrument to the valve or
valves of the reed cell or cells by which a more simple and more efficient connec-
tion of the keys with the valves of the reed cells or wind box is obtained than
heretofore.
In order to enable others to make and use my invention I will now proceed
to describe its constructions and operation in referring to the accompanying
drawings, in which
Figure 1 is an elevation of the improved parts of the musical instrument
partly in section,
Figure 2 is a plan of a part of the arrangement shown in Figure 1,
Figure 3 is an elevation of a modification of devices shown in the former
figures, whilst
Figure 4 represents a modified part of the invention and
Figures 5 and 6 illustrate in a plan view and a front view respectively parts
of the devices shown in Figures 1 to 3.
Similar letters of reference indicate like parts.
a indicates the key in operating which the lever c is turned around its fulcrum
(in the ledge b) by means of the stud a. The stud is adjustable in its position
towards the key. The movement of the lever c is cominunicated to a second
lever ff arranged with its fulcrum in the rail e on top of the cell or box by
means of the connecting rod d so that the arm f of this lever presses down by
means of a rod guided in the wall of the box and provided with a stud h on top
of which rests the lever arm f¹, the arm g' of the valve lever arranged inside of
the reed box whereby the valve g is opened so that the reed sounds. For the
purpose of simultaneously actuating two or more reeds by means of one single
key the lever g may be arranged as a double armed lever (see Fig. 1) the
arm operating a like lever provided in the adjacent cell by means of a rod i
guided in the wall which separates both cells, and so on.
In the modification according to Figure 3 the lever f is appropriately con-
nected with the base plate of the box; consequently the rod d which may, as
shown in Figure 4, consist of two pieces connected by a hinge, which is suitably
guided for instance by a lever d, has been elongated-to meet the lever f and the
inner lever gl has become a double armed lever.
The manner in which the levers f actuating the rods h are arranged is illus-
trated in Figure whilst Figure 6 exhibits the arrangement of the connecting
rods which transmit the movement of the levers the levers f.

page_text: I do not confine myself to the precise form and arrangements of the several
parts and devices of my invention as above described as they admit of various
modifications without departure from the principle of its construction and
operation.
Having now particularly described and ascertained the nature of my said 5
invention, and in what manner the same is to be performed, I declare that what
I claim is:
.
1. A mechanism for connecting the keys of an organ or like musical instrument
with the valves of the reed cells or wind box comprising a rod d connecting a
lever c actuated by the key by suitable intermediate means with a lever f and 1
means for transmitting the movement of this lever to the valve, essentially as
described.
2. A mechanism for connecting the keys of an organ or like musical instru-
ment with the valves of the reed cells or wind box comprising a rod d connecting
a lever actuated by the key by suitable intermediate means with a lever f 1
and a rod guided in the cell-wall and provided with a stud h upon which the
lever rests, essentially as described.
