VISITGRS’ SPEAKING DEVICE FOR JAILS
George Edward Oliver, Brooklyn, N. Y.
Application September 28, 1937, Serial No. 166,090
14 Claims.
This invention relates to a visitors’ speaking
device for jails and the like and has for an object
to provide a tamper and bullet proof device which
is arranged to prevent passage of materials bee
Cn
tween the prisoner and the visitor.
,
Another object is to provide an eñicient, con
venient and dependable device of the above type.
Various other objects and advantages will be
apparent as the nature of the invention is more
complete cover which prevents access to any part
of the speaking device. It will be noted that the
rivets 2E are concealed by the frame I8 and that
the screws IS are concealed by the shelf I4. The
ends of the shelf I4 may be closed by depending
members Ilia so that there is no possibility of
either the prisoner or the visitor removing the
device in the short time available. The housing
may, of course, be mounted in other ways, such
fully disclosed.
as by brackets extending from the partition I2, 10
Although the novel features which are believed
to be characteristic of this invention will be more
in which case the shelf E4 may be omitted, or
the closure for the device may not be complete
particularly pointed out in the claims appended
hereto, the invention itself may be better under
provided supervision is exercised to prevent tam
stood by referring to the following description,
taken in connection with the accompanying draw
ing forming a part thereof, in which a particular`
embodiment of the invention has been shown for
purposes of illustration.
Referring to the drawing:
Fig. 1 is a longitudinal section through a speak
ing device embodying the present invention;
Fig. 2 is an end elevation showing the mouth
of the speaking device; and
Fig. 3 is a section taken on the line 3_3 of
Fig. 1.
In the following description and in the claims
certain specific terms are used for convenience
. in designating various details of the invention.
It is to be understood, however, that these terms
pering. In the form shown the housings are
supported by the frame i8 and may be removed 15
by dismantling the same. They may, if desired,
be also attached to the partition I2 at their inner
ends in which case the outer support may be
omitted.
The outer end of the housing I5 is covered by 0
a screen 30 of suitable material, preferably bullet
resistant, such as wire mesh which is of sufficient
ly close weave to prevent- passage of any solid
material. The opening il is covered on each side
by a screen which comprises a perforated steel 2
plate 32 covered by a wire screen 3I of ñne
mesh. This screen 3| may be compacted by roll
ing or pressing so as to strengthen the wires
at their intersections and also to reduce the
size of the openings therein. In the form shown
are to be given as broad an interpretation as the
a pair of such screen assemblies are mounted
state of the art will permit.
Referring to the drawing more in detail, the
invention is shown as comprising a pair of speak
Li ing channels I0 and II, located on opposite sides
of a partition I2 which separates the prisoners’
on opposite sides ci the partition I2 with the
wire screens 3l toward the partition and held
space from the visitors’ space. The partition I2
is provided with a window I3 of bullet proof
glass or the like through which the prisoner and
visitor may be seen.
In the embodiment shown a horizontal shelf I4
extends outwardly on both sides of the partition
I2 below the window I3. This shelf supports
flared housings I 5 which are mounted on opposite
by rivets £93, one assembly being associated with
each of the housings I5. It is to be understood
that the construction of the two housings I5 is
identical, one of the devices extending into the
visitors’ space and the other device extending
into the prisoners’ space. The screens 30 are
inclined so as to receive sound waves from a
point somewhat above the speaking device and
corresponding to the normal positions of the
prisoner and visitor.
The screens 30 and Si are so disposed that it
C: sides of the partition I2 and form the speaking
is practically impossible to thread even the finest 45
channels Il] and II. The inner ends of the hous
ings I5 are located in alignment with an opening
I1 below the window I3 in the partition I2. At
the larger or outer end, each housing I5 is pro
v. O vided with a circular flange 22 which is attached
to a frame I8 supported by the shelf I4 and at
tached thereto by suitable means, such as screws
I9 and clamping bars 20. The frame is also at
tached to the partition I2 at a point above the
housing I5 by means of rivets 2I and forms a
wire through the device.
The apertures in the '
two plates 32 may be out of alignment so that
direct passage through the two plates is pre
vented. In some instances the screens 3| may be
omitted and a bullet prooi perforated plate or 50
plates substituted therefor on both sides of the
partition or a single plate or screen assembly may
be mounted within the opening I'I. The screens
30, of course, need not be inclined as shown al
though this arrangement provides a maximum 55
2
2,113,800
audibility and at the same time avoids a straight
path through the device. The screens 3| or plates
32 may also be made of bullet resistant material
if desired.
In the form shown, the lower side of the outer
portion |5a of the housing l5 is substantially
horizontal and the inner portion 15b is somewhat
inclined toward the partition I2. In order to pre
vent passage of fluids through the device an
10 aperture 35 is provided in the plate 32 com
municating with the opening l1 and extending
to the visitors’ side of the device so as to dis
charge any ñuid on to the shelf I4 in the visitors’
space. An aperture 35 may be provided in this
15 shelf adjacent the aperture 35 so as to discharge
such fluid on to the floor if desired.
It will be noted that the above construction
permits free passage for sound waves between
the prisoner and visitor, but prevents passage of
20 any liquid or solid materials therebetween. If
it is attempted to pass liquids they are irrimedi
ately discharged on the visitors’ side and do not
reach the prisoner. An electric alarm system
may also be used to warn of any attempt to pass
25 objects through the device. It is to be under
stood that the form thereof may be changed in
various particulars and that a particular em
bodiment has been shown for purposes of illus
tration only. Various changes and modifications
30 may be made therein as will be apparent to a
person skilled in the art. The invention is only
to be limited in accordance with the following
