4 Claims. (Cl. 189-7 )
This invention relates to devices for locking and
operating doors of prison cell blocks. In prison
cell blocks it is usual to have a number of cells
placed in a row with individual doors for said
'5 cells giving access to a corridor, and there is
usually provided a waiting room or the like which
is separated from the corridor by an escapeprooi
door. In the past it has generally been the prac
tice to provide these doors with individual locks,
0 the keys to which were carried by a ward-en‘ or
other person in authority. To unlock any of
the doors the individual in whose charge the
keys were placed, had to enter the cell block, and
was subjected to the danger of attack by one .
15 or more of the prisoners.
It is an object of our invention to provide a
mechanism whereby all the doors in the cell
block may be controlled and operated from a
station removed from the cell block. It is an
20 other object of our invention to provide means
whereby any of the doors in the cell block may
be opened or closed individually or any number
of the doors may be opened or closed simultane
It is also an object of our invention to provide
a mechanism as above outlined whereby not only
doors which are aligned in one plane, but also
doors which are disposed transversely to said
plane may be actuated.
Another object of our invention is to provide
means whereby when the cell doors are opened
they are locked in open position, so that one of
the prisoners could not push the door to a locked
position, and thus possibly con?ne one of the
35 prison officials.
Other objects of our invention include the pro
vision of means whereby'the operating mech
anisms are tamper-proof and cannot be injured
or destroyed by the prisoner.
These and other objects of our invention which
will be pointed out hereinafter or which will be
apparent to one skilled in the art upon reading
these speci?cations, we accomplish by that cer
45 tain construction and arrangement of parts of
which we shall now describe an exemplary em
bodiment. It is to be understood that we do
not intend to be limited otherwise than as pointed
out in the claims to follow, and that modi?ca

Referring to Figs. 1 and 2, the cell block may
consist of a front partition or wall A, side walls
B and C and a rear wall (not shown) which, ex 35
tending across the rear of the unit completes a
rectangular enclosure.
_In side wall B we have provided an entrance
gate or door ii, hinged as at 8a to permit passage
to or from the cell block. The interior of the 40
cell block has other partitions or walls ‘i, 8, 9
and ill, which with the sliding gates la, 2a, 3a,
and 4a divide the unit into a plurality of en
closures which we have indicated at l, 2, 3, 1! 45
and 5. For the purpose of this speci?cation we
shall term the enclosures i , 2 and 3 as cells. The
enclosure 4 may be termed a corridor, and that of
5 a vestibule.
The partitions and gates above mentioned may
be of the usual type steel. grating such as is
common to prison construction, or they may con
sist of armor plate or other material if desired.
A ceiling E5 of grating or plate material is
provided to cover the entire cell block. The floor 55
may be of reinforced concrete or other suitable
material to form an escapeproof structure.
For operating the various gates we have pro
vided a central control box F which is mounted
outside the cell block on wall B. This control
box contains apparatus by which the, gates may
be opened or closed without the attendant enter
ing the cell block where he may be subjected to
physical violence.
a short rack 29a, which rack is ?xed to the struc
tural wall portion 30 extending from the gates
and grill work to the ceiling. Also meshing with
the pinion 25 is a longer rack 3| which as better
seen in Fig. 3 is secured to a long channel mem
ber 32. The rack 31 may have a second toothed
portion am. from which motive power for operat—
ing the corridor gate 4a may be derived. The
member 32 is mounted for reciprocal movement

limited to the precise lay-out or arrangement of
the cells and corridors as shown in the drawings
for it will be apparent after reading the accom
draw-bar which is common to the gates of cells I,
2 and 3. Thus it is apparent that movement of
the hand lever 25 is transmitted to the draw-bar
32 and if any of the cell gates were coupled there
with they would be carried to open or closed posi 15
tion as desired. As will be presently described
we have provided means by which the gates may
be selectively coupled with the draw-bar. This
coupling means is actuated by depressing the
required tabulated lever l5’, H5” or IB’”.
Referring to Figs. 3 to 7 inclusive, each cell
gate has secured at its top a rectangular plate
35 having studs 36 upon which ?anged rollers 31
are mounted. The rollers 31 are adapted to
panying description that with slight mechanical
15 modi?cations the arrangement of the cells and
the location of the control box may be varied in
many ways.
Referring to Figs. 11 and 12 the control box F
has a series of tabulated levers i6’, I6” and IS’”
pivoted at l?al and mechancially connected with
a series of pull rods H’, it” and W”. These
particuar levers control mechanism of the gates
of cells i, 2 and 3, respectively, as will later be
described. A lever l8 pivoted at 18a and con
nected with pull rod is controls mechanism of
the corridor gate 4a. Lever 25 is pivoted at 2541
and through action of the link 2! operates a
ride on a track member 38 which is secured to 25
the structural wall portion 30.
Rigidly mounted
latch or tongue 22 which is the locking means
on the plate 35 is a member 40, having a nose
portion 40a, a shoulder 4th and a forward pro
for the vestibule gate 5. A lever 23 pivoted at
23a has another pivoted connection 231)‘ to which
jecting angular portion 45o, as best seen in Fig.
a plate 24 is connected. Plate 24 is slidably
mounted on the sloping dividing wall 24b in the

lug 41b.
box F, and has openings 24a which surround the
aforementioned levers. Depression of the lever
23 causes the upper edges of the openings Elia,
to contact and move levers i5, i8 and 25 thereby
operating or releasing the desired mechanism of
all the gates in one operation. It is thus seen
that control of the gates may be performed selec—
40 tively or collectively as desired. The control box
F may be provided with a hinged cover i I having
locking means ila.
As seen in Fig. 14 angle
pieces I lb may be mounted on the cover so as to
prevent any movement of the various levers when
45 the cover is closed.
Motive power for opening the gates is provided
by manual operation ‘of the hand lever 25 as
will be described later.
The gate 6 is an excep
tion to this, however. As shown it is of the
50 hinged type and is provided with a handle for
operation in the usual manner.
We wish to be understood that the number of
gates shown in the drawings is not a limitation
of our present invention, nor is the manual
operation thereof an essential requirement, for
in some cases as where a large number of gates
are to be operated it may be desirable to provide
electrical or other motive means.
The hand lever 25 is pivoted at 25a in a pair
(SO of arms 25 and ‘25a which in turn are pivoted at
2th and have upwardly extending portions 26c
in which a link 2? is pivoted on the pin Zia.
Hand lever 25 has a toothed portion 25b which
meshes with a gear segment 28 rigidly secured
in the box F.
As seen in Fig. 12 the hand lever 25 is shown
in its extreme upward position. Movement of
this lever to its downward position as seen in
Fig. 13 will cause counter-clockwise movement
of the arms 25 and 25a thus pulling link 2?‘ to
the left. Conversely the movement of lever 25
from its lower to upper position will cause link
21 to be carried to the right.
Referring to Fig. 2 the link 2‘! has mounted at
its outer end a traveling pinion 29 meshing with
Carried on the member 45 an arm or dog 4| 30
Mounted on the draw-bar above each gate is a
pair of latches 43 and 44.
These latches are
pivotaliy mounted on studs 43a and 44a, respec
tively, and are limited in their movement there
on by pins 531) and 441) which are ?xed in the
draw-bar and extend through the slots 43c‘ and
440. The latches have inclined surfaces 43d
and 44d.
Faces 43c and Me of the latches are 40
adapted to engage the portion Mb of the dog
4| when said dog is turned upwardly about its
pivoted mounting Ma. Thus the dog 4| and
latches 43 and 44 constitute a coupling means
by which the movement of the draw-bar is trans
mitted to the gates. The latch 43 serves to carry
the gate to the right or open position, as seen
in Fig. 5. Latch 44 operates to return the gate
to its closed position.
Referring to Figs. 5 and 6 we have secured to 50
the structural wall portion 30, a bracket 50
having a triangular shaped portion 5% supported
in inter-spaced relation to the wall 30 by webs
55a. Pivoted at 5! is a member 52 having a lever
arm 52a to which is attached the pull rod l'l’
previously mentioned. Member 52 also has an
extending cam portion 52b with inclined faces
52c and 52d. A slot 52s in member 52 has
slidably mounted therein a stud 53. This stud
extends through a slot 550 in the bracket 50 and 60
is rigidly secured at its inner end to a member
54 which member has a rectangular opening 54a
adapted to receive the nose 40a of member 40.
For the purpose of this speci?cation the member
54 may be termed a keeper. When the gate is 65
carried toward its closed position as seen in Fig.
3, the nose 40a. contacts the upper edge of open
ing 54a lifting the member 54 upward. During
this action stud 53 is free~to rise in slots 52c and
55p. When the gate reaches its closed position 70
member 54 drops behind the shoulder 40b as seen
in Fig. 4, thus locking the gate in closed posi
tion. Member 54 has a lug 54b to which is ?xed
alift rod 55. This lift rod'serves to operate an
auxiliary locking device for the gates.

It is not essential that the draw-bar and latches

this draw-bar a rack 11 meshes with gear 18
which gear is in turn mechanically connected
50 with draw-bar 32 by means of the miter gears 19,
shaft 80, gear BI and rack 3|a. Movement of
draw-bar 32 is therefore transmitted to the sec
ondary draw-bar 15, but in transverse relation.
For releasing the keepers and lifting dog 4|
55 the member 52 is connected to a bell crank 85
pivoted at 85a on bracket 50, said bell crank 85
being connected by pull rod |9 to the tabulated
lever l8 within control box F. Latch members 82
and 83 carried on the draw-bar 15 are adapted to
60 engage dog 4| and carry the gate to open or
closed position as previously described in con
junction with gates Ia, 2a and 3a.
The operation of the gates is as follows:
Assuming that the gates are in closed position
65 and it is desired to open gate la, the operator
opens control box F and depresses the tabulated
lever l6’. As seen in Figs. 3 and 4, this actuates
the pull rod l1’ and causes clockwise rotation of
member 52 until said member strikes the projec
70 tion 400 which is integrally mounted with the
gate. Rotation of member 52 acting through
stud 53 lifts the keeper 54 out of locking engage
ment with shoulder 40b. The auxiliary keeper
5‘! being mechanically connected with keeper 54
75 by lift rod 55 is also lifted from engagement with
it will not rise between the latches 43 and 44 as
seen in the drawings. However due to the pivoted
arrangement of the latches and their inclined
surfaces 43d and 44d they are adapted to ride 50
over the dog and fall into engagement therewith.
Referring to Fig. 2 it will be apparent that the
appurtenances of gate la as described .are sub
stantially duplicated in conjunction with gates
2a and 3a, and are therefore designated by similar
indicia on the drawings. The operation of these
gates would therefore be accomplished as just
described for gate |a, except that the operator
must depress the appropriate tabulated lever I6" 60
or | 6"’ as required. Similarly the transverse gate
may be actuated by depressing the tabulated
lever l8.
From the construction of our device it will ap
pear that as the operating lever 25 is raised to the 65
position shown in Fig. 12, the draw-bar is pushed
toward the right as seen in Figs. 1 and 2, and
that when the operating lever 25 is lowered to the
position of Figure 13, the draw-bar is pulled
toward the left. Thus an upward movement of 70
the handle 25 serves to open any cell door which
has been coupled to the draw-bar by means of
the tabulated levers, and a downward movement
closes any open door which is coupled to the
draw-bar. If, for example, the doors la and 3a 75
are open and the door 20» isclosed, and the lever
20 is depressed, the effect of an upward movement
of the lever 25 will be to open the door 2a, the
doors la and 3a remaining open. Now if the
lugs for any number of said doors to enter into
engagement with said dogs, whereby said doors
may be selectively operated from said control box.
2. A cell door operating mechanism comprising
lever 20 is again depressed, all the doors will be
in combination with a cell door, a draw bar pro
vided with dogs, a projecting shoulder on said
door, .a keeper adapted to rest behind said shoulder
to lock said door in closed position, a lug on said
door, and means remote from said door to lift
closed upon downward movement of the lever 25.
If the operating handle 25 is down, and some of
the cell doors are open and others locked, and it
is desired to close all open doors without opening
any of the closed ones, the handle 25 is raised to
its uppermost position without depressing any of
the tabulated levers, and then the lever 25} is de
pressed. Now upon downward movement of the
lever~25, all the open doors will be closed since
they have all been coupled to the draw-bar by
means of the lever 20.
It will thus be seen that we have provided a
jail block in which, regardless of the instant posi
tion of any of the gates, an attendant may at
