Improvements in Means for Indicating or Denoting the Occupiers or
Tenants of Residential Chambers, Flats, or the like.
I, WILHELM HANEMANN, of 57, Friedrichfelderstrasse, Mannheim, Germany,
Mechanician, do hereby declare the nature of this invention to be as follows:-
The invention consists of an indication of lodging occupiers or tenants per flats
in the same building, whatever the number of flats and of tenants.
The system is caracterised by a case placed on the front of the house. The
front of this case has as many openings or horizontal windows as there are flats;
placed behind each window a revolving prism is supported by trunions passing
through holes in the side walls of the case; one of the trunions has a winged nut
to allow of the prism being turned by hand.
The prism of each window of the case possesses as many faces as there are
different tenancies in the corresponding stage, each face receiving by a slide
adapted for the purpose a card bearing in print or manuscript the names of the
tenants living in the flat in question.
If the flats possess only one tenancy each, the revolving prisms are substituted
by fixed plates behind the windows, which are also furnished with slides; in both
cases the names of the tenants can at will be removed or placed in the indicator
on departure or arrival.

Improvements in Means for Indicating or Denoting the Occupiers or
Tenants of Residential Chambers, Flats, or the like.
I, WILHELM HANEMANN, of 57, Friedrichfelderstrasse, Mannheim, Germany,
Mechanician, 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 present invention concerns an indicator for the tenants of a house, whatever
be the number of flats and tenants.
In the annexed drawing Fig. 1 is an elevated view of the apparatus, Fig. 2 is a
transverse section, and Fig. 3 a vertical section of the same, while Fig. 4 and 5
show an elevated view and a transverse section of a modified construction.

page_text: The apparatus is composed of a box A in wood or better in metal, provided with
two perforated lugs to fix it to the front of the house (Fig. 1, 2 and 3).
In the face of this box are as many superposed openings or windows as there are
of flats. Behind each of these windows is a horizontal prism B, which can turn
or pivot on its axle, the two extremities of which rest in corresponding holes made
in the lateral sides of the box; on one side the axle is terminated by a winged
nut C.
The prism possesses as many horizontal faces as there are of apartments on the
story with which it corresponds; it may be triangular, quadrangular,
pentagonal, etc.
Each face of the prism has a slide D, allowing a card to slide into it, upon which
card the name of each tenant is written or printed. When a tenant leaves, it is
easy to remove the card bearing his or her name and to substitute it by that of
the new tenant.
In the example shown in the annexed drawing, we take a four story house;
each story having four. different apartments. For houses where there is but one
apartment on each floor, I have contrived another means by substituting the
rotary prisms by fixed plates having slides B1 (Fig. 4 and 5).
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed 1 declare that what I
claim is:-
1. A tenants' indicator, distinguished by a box A to be fixed to the front of a
house, this box having a number of horizontal openings corresponding with the
number of floors, and a hand rotating prism B behind each opening, having as
many horizontal faces as there are of apartments on the corresponding floor, each
face receiving in a suitable slide D, a card bearing the name of the tenant living
on the said floor.
2. For floors comprising only one apartment, a modification of my indicator, con-
sisting of fixed plates with slides B¹ to substitute the prisms.
3. A tenants' indicator, substantially as described and shown.
