7 Claims.

This invention concerns itself with improvements in jail locking devices and the like. The invention relates particularly to improvements intended for installations in jails and the like,

but it will presently appear that the features of the invention may also be used in connection with locking device installations for asylums and other institutions where it is desired to ensure against escapes of the prisoners, as Well as permitting various operations of locking and unlocking to be performed for the doors of the various cells or rooms.

Generally speaking the invention relates to improvements in locking devices for the doors wherein the doors are hinged to swing, as distinguished from those cell door arrangements in which the doors slide back and forth along a trackway. Furthermore, the features concern arrangements in which the various cell doors of a group or gang may he controlled in various groupings, and for various conditions of locking and unlocking, all as will be presently explained. In this connection it may be mentioned that the present arrangement is one in which the locking im devices for the doors of a gang may be gang controlled from a gang station under control of the warden or his deputy; and an arrangement such that the locking devices may he placed in the deadlocked position, in which each cell lock is deadlo'cked so that it cannot be unlocked "oy a key inserted into the lock of suoli cell; or a` key lock position, in which the lock of any individual cell door may he locked or unlocked by use of a key inserted into the lock of such cell, the locks of the other cells being left in their previous conditions; or an open position in which the locks of the cells are moved to the disengaged position so that the cell doors may be swung open without the need of key manipulations at the various cell doors; and a front cover plate release position, in which the various cell locks are retained in their deadlocked condition, but the front cover plates are released so that said plates may be removed for inspection or repair of the various locking devices which theyl protect and conceal.

Generally speaking, it may be stated that the construction herein disclosed is such that by movements of a single controlling and operating bar the locking devices are both controlled as to their conditions of locking or unlocking, and are also operated for unlocking operations under cer tain desired conditions. That is, a single bar serves 'both as a controlling and an operating oar for the locking devices.

Usually an installation of the swinging door type is one in which the actual movements of swinging the doors open or closed are performed by the prisoners in the several cells, the'gang mechanism serving 'to take care of the locking devices only. In such an installation it is desirable to ensure proper closure of all the cell doors before the gang locking har is moved to the locking position, as otherwise a prisoner or a number of prisoners might manage to hold their 'doors slightly ajar when the gang loar was moved to the locking position, thus preventing proper functioning of their respective door locking devices, and making escapes possible after the gang bar had been moved to the deadlocked position. One feature of the present invention is to make pro- Vision for preventing movement of the gang bar to the deadlocking position unless all of the doors of the gang of cells have been moved to the Closed position wherein they Will he properly locked when the gang 'bar is moved finally to its locking position. In case the door of any cell is not in its fully closed position the gang bar cannot be moved to the locking position, and the warden or deputy is thereby informed that one or more cells are not in the door closed condition.

Another feature of the invention relates to the provision of an arrangement such that when the gang bar is moved to the key position, the bolt of any one or more door locks may be key moved to a deadlocked position wherein the same is isolated from the gang bar operations, so that movements of the gang har under such condition will not serve to operate such lock bolt, but such lock holt will remain in the projected locked position, with such cell door locked and isolated from the opened or unlocked doors. This makes it possible to treat any given cell door individually, so that the various prisoners may be given individual treatment when necessary. 40-

Another feature of the invention relates to the provision of an arrangement such that when the gang bar is located or placed in the key position, the door of any given cell or cells may be snapped shut, the lock bolts of such doors snapping to locking position as their several doors are shut. By this arrangement, when the gang har is placed in the key position, the various cell doors will lock as they are shut individually.

Another feature of the invention is to provide an arrangement of very simple but sturdy construction; an arrangement such that a minimum number of parts are used, of simple form, and so related that they will not readily get out of order; an arrangement such that when the cell doors are closed the possibility of tampering by the prisoners is reduced to a minimum; and an arrangement such that in case of damage to any individual cell lock the improper functioning or lack of functioning of the same will not interfere with the proper functioning of the remaining cell door locks and parts. It is also an object to make provision for proper adjustments during installation, so that when the locking devices and controls for a gang of considerable length are installed, the parts will be brought into proper operative relationship, notwithstanding material errors of positioning ci the various cell frames y and parts, measured from the gang operating box wherein the gang levers, etc., are placed.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction, and

combinations of parts hereinafter described and` claimed.

Figure 16 shows a fragmentary face view of the mechanism box, showing especially the cover plate locking device.

Referring rst to Figure 9, I have therein shown the cell door 20 for the end cell of a gang, as being typical of the doors of all of the cells of such gang. This door is hinged at 2l and 22 in the well understood manner. Mounted on the door opening frame is the locking device 23, the details of which will be disclosed hereinafter; but it may be here stated that this locking device includes the bolt 24 which may engage the door or a suitable xture thereon to lock the door shut. This bolt may be retracted or withdrawn to unlock the door.

Mounted on the door frame above the door opening is the mechanism box 25; and the horizontally movable master or gang bar 25 enters such box, so that when such bar is moved back and forth horizontally it will properly control and operate the locking devices. This gang or master bar extends through the various mechanism boxes of the cell doors, from the position of the control box 2l at the gang control position, to the most remote cell of the gang. This control box is provided with the usual cover 28, which may be hinged as shown at 29 in the usual manner.

Referring now to Figures 12 to 16 inclusive, I have therein shown more in detail the principal parts of the locking and control devices for a typical cell installation; and it may be noted that in so doing I have shown the same as used in connection with a cell door provided with bars instead of a solid plate, as` previously shown in `The door frame conveniently includes the channel member 3!! which is built into the concrete or masonry structure 3i (see Figures 9 to 13 inclusive), but I do not intend to limit the features of my present invention to such construction.

The mechanism box 25 is made of a channel member 32, the flanges 33 and 3d of which 4constitute the top and bottom of the box when installed, and the ends of the box are formed by the sections or plates 35 and 36 secured to the channel of the box by the angle members 3l `and 38. The cover 39 of this box is in the form of a plate of proper size, and the xtures l5 and 4| are secured to the ends 35 and 36 of the box, as by welding. Secured to the inner face of the cover 39 at one er1-d is the hook or nger 42 which may be engaged behind the fixture ll when the cover is properly set into place. Also secured to the inner face of the cover are the angles i3 and IM, and the lock bar 'l5 is slidably extended through the flanges of these angles, so that said bar may be moved back and forth. One end of this lock bar is adapted to engage behind the fixture M when the cover is set into place, and the other or inner end of this lock bar is provided with the upwardly extending finger i6 (see Figure i6), which nger carries the adjustable pin or screw il?. The bar 45 also carries the washer or plate d8, and the spring 49 is set between the plate 48 and the angle 43 so that said spring tends to move the bar 45 to right or cover locking position. The right hand end of the locking bar L15 is beveled so that when the finger or pin 42 has been set behind the fixture 45 at the left hand end of the box, the cover may then be forced back at its right hand end and the pin l5 will snap behind the fixture 4I to lock the cover in thereof prevented.

'. ment of the bar would be prevented.

place. If desired, screws 50 and 5l may also be provided for securing the cover in place.

. lt was mentioned that the master or gang bar 25 extends horizontally through the mechanism box. For this purpose said bar passes through suitable openings in the ends 35 and'36 of the box. There is a bell crankl 52 pivotally mounted on the back Wall or channel 32 of the box, so that said bell crank may swing on the pivot 53. One arm d of this bell crank reaches up behind the master bar 26, and the other arm 55 thereof swings behind the master bar and through the horizontal position. Secured to the master bar Within the mechanism box for each cell door is a plate 55, `and said plate carries the backwardly reaching pin 5l' which extends into the path of the arm 54 of the bell crank so that as the master or gang bar moves back and forth the bell crank will be rocked accordingly. The plate f` 56 is secured to the gang bar by screws extending through. the slotted openings 53 and 5S, so that the exact position of the plate 56 may be adjusted to ensure proper operations of the locking devices of the .cell in question, and to compensate for inaccuracies in the setting oi the cell frame, etc.

Preferably the gang or master bar is guided in its movements by the grooved roller Within the mechanism box and close to the plate 55, so as to ensure more accurate operations.

The gang or master bar carries a bell crank 5l Which is pivoted to the bar at the point 52, and swings adjacent to the back face of the bar. `The arm t3 of this bell crank may stand in the horizontal position of Figure 14 wherein, when the z master or gang bar is moved to the left said arm will engage with the stop pin 5i which is adjustably mounted in the lug 55 on the back of the mechanism box. Under such condition the left hand movement of the master or gang bar will be interrupted, and further left hand movement On the other hand, by swinging the bell crank 5i counterclockvvise, the arm 63 will be moved down low enough so that as the gang or master bar moves to the left said arm will not strike the pin 64, and the left hand movement of the bar may be continued without interruption. The bell crank 6l includes the vertical arm 55 which may be engaged by a suitable part of the cell door when said door is closed so that under such condition the bell crank will he swung counter-clockwise as the left hand movement of the gang bar is performed, thereby ensuring and permitting continued movement of the gang or master bar without interruption.

. Said vertical arm 65 is heavy enough to normally f bar travels towards the left, and said bell crank will swing as it travels so that its arm 53 will not engage the stop ld, but the bar will be allowed to continue its travel. On the other hand, in case the cell door should not be fully closed, its finger 5d would not be projected far enough into the mechanism box to properly interfere with the bell crank arm 555, and the bell crank would not be rocked, but its arm 63 would stand in the line of the stop pin iid, so that further leftwardrnove- Such fact stance.

Referring now to the locking device 23, I will explain the construction and mode of operation of the same in detail; This lock includes the housing or box 'lil which is suitably secured to ie door frame ory other part. The bolt 24 is slidably extended through said box, and when projected reaches over into the path of the edge portion of the door. The door carries the lock strike il which engages the beveled end portion of the bolt when the door is closed While the bolt is in projected condition.

The lock includes the usual cylinder 12 to receive the key in the opening 73. The bolt 24 is provided with the lug i4 in position to be engaged by the tumblers l5 under certain conditions. Ihe bolt 2dmay be moved back to the left from the position of Figure 14 against its spring, and without the need of key operation, so that under such conditions it may operate as a spring lock. This bolt may, however, be projected by a special movement to the right into the dotted line position '16 (see Figure i4), wherein the lug 'I4 will be in the dotted line position 'il at the right hand of the lock tumblers 15. This special movement of. the bolt may be accomplished by turning the look -cylinder a full turn over to the right. The lock strike il is made of proper size to acccommodate the bolt when thus fully thrown to the right.

There is a vertically movable dead lock bar 'I8 extending vertically through the lock box 'I0 behind the bolt 2d. This bar 'i8 carries the pin 19, so that when the bar is lowered from the position of Figure'll, said pin 'i9 may enter into the notch im on the upper edge o1" the bolt, and cause a dead locking condition to be Created. Therefore, when the bar 'It is lowered sui'liciently to engage the pin 79 with the notch 8l) the bar or bolt of the lock cannot be moved by insertion of a key into the cylinder 12', but the cell door Will be deadlocked until the bar i8 is again raised by proper extraneous manipulation thereof.

The bar 'i8 is connected to the arm 55 of the bell crank 52 in the mechanism box by means of the rod 8|. This rod reaches vertically through the vertical 'housing including the channel 82.

- lThis channel reaches down from the mechanism box to the lock box, and is suitably secured to the permanent structure by screws 83. This vertical housing is provided with the removable cover plate tl, the lower end of which carries the hook 55 secured to its inner face and adapted to enter into a socket or recess in the top of the lock box. The mechanism box cover Sil has the short angle bracket 35a which, when the cover plate is set into position will overlie the upper end of the cover plate 84. Therefore, when the mechanism box cover 35i .is set into place the angle section 38a will lock the cover plate Sil against any upward movement so that the same is locked in place. Sil from the mechanism box, the cover 84 may then be raised and unhooked at its lower end and Conversely, by first removing the cover arm 54.

L left, thereby unlocking the door.

then completely removed. One or more supplemental clips 40a may be provided in the cover plate 84 for additionally securing the same, if desired. In this connection, it is noted from examination of Figure 14 that the mechanism box may be adjusted up and down with respect to the permanent structure by provision of the slotted openings 86, through which the securing screws for the mechanism box are extended.

It will now be seen that as the gang or master bar 26 is moved back and forth the rod 8| will be moved up and down to carry the pin 19 alsoy up and down. Thus the movements of this deadlocking pin are controlled by the back and forth movements of this gang or master bar. It should also be noted that movements of the gang or master bar to the left will permit the deadlocking bar`18 to move down until the pin 19 engages either the upper edge of the bolt 24, or the notch therein, or any suitable projection extending upwards from the lock bolt 24, but further left-hand movement of the gang or master bar may be accomplished due to the fact that the plate 56 with its pin 68 will draw away from the bell crank Right hand movements of the gang or master bar will cause the dead lock bar 18 to rise as soon as the pin 68 engages the arm 54.

On the back face of the bolt 24 there is secured the cam or wedge shaped plate 81; and the dead lock bar 18 carries the roller 88 in position to engage the wedge face or edge of this plate. When the dead lock bar is raised from the position of Figure 14 the roller 38 will engage the Wedge face or edge and force the lock bolt to the This plate 81 is of such size, that when the lock bolt is moved to the right the extra or special distance shown by the dotted lines 16 (see Figure 14), the roller 88 will, under such conditions, pass to the left hand edge of the plate S1 when the dead lock bar is raised, thus making it possible, when the lock bolt is moved the special or extra distance to the right to move the dead lock bar up and down without operation of the lock bolt. In other words, under these conditions, the movements of the bar 18 up and down will not lock and unlock the door, but will allow it to remain in the deadlocked or isolated condition in which it has been placed by such special right hand movement of the lock bolt.

I'shall now explain more in detail the various K operations and movements which may be performed by the structures heretofore disclosed herein. For this purpose reference may be. had to Figures 1 to 8 inclusive which show diagrammatically the various positions of the principal operative parts. I will mention that there is a pin 89 carried by the master or gang bar within the mechanism box, said pin extending backv wardly to a position where it will limit the clockwise rotation of the bell crank 6l so that the arm 63 thereof normally stands in line with the stop 64 as shown in Figure 14, and for this purpose there may be provided a spring normally holding the bell crank in the position of Figure 14. The pin 89 also extends forwardly from the master or gang bar into line with the pin 41 on the Cover plate lock bar l5 as shown in Figure 16.

Referring now to Figures l to 8 inclusive, the position of Figures 3 and 4 may be termed the normal deadlocked position. Assuming that the door is fully closed so that the pin 63 extends through the mechanism box cover plate into line with the bell crank arm 66, the bell crank 6I has been tilted as shown in Figure 3, and the arm 63 key to its lock cylinder.

. bar.

thereof has not struck the pin 64, so that the master or gang bar may be moved still further to the left. Such further leftward movement to the position of Figures 1 and 2 will cause the pin 89 to engage the pin 41 (see Figure 16) and slight further movement of the bar to the left will carry the locking bar 45 to the disengaging position so that the mechanism box cover plate may be removed. This is the condition illustrated in Figures 1 and 2.

Referring again to Figures 3 and 4, it will be noted that in such position the bell crank 6| has tilted to a position to allow the deadlock bar 18 to move down low enough tol engage the dead lock pin 19 with the notch 80 of the lock bolt Z4 (see Figure 14). In this position the lock bolt cannot be withdrawn to the left by key operation, due to the engagement of the pin 19 with the notch 80, so that the cell lock is deadlocked against key operation. The lock bolt is therefore held against leftward movement both by the lock mechanism itself, and also by the engagement of the pin 19 with the notch 80.

By shifting the master or gang bar 2,6 still further to the right to the position of Figures 5.and

6 the pin 51 of the plate 56 has engaged with the arm 54 of the bell crank 52, and has rocked the same sufficiently to raise the rod 8l and deadlock bar 18 to carry the pin 19 out of the notch 8l! of to the left by key operation, to unlocky the cell door by said key operation. In this position of the parts, all of the cell doors may be retained inthe key locked position, and no cell door may be released or unlocked except by application of the Also, in this condition of the parts, any cell door may be latched in locked co-ndition by merely slamming it shut, due

to the spring nature of the lock bolt movement.

Further movement of the master or gang bar.,

to the right from the position of Figures 5 and 6 to that of Figures 7 and 8, will rock the bell crank 52 still further so that the rod 3| and dead lock l bar 18 will be raised still further. This movementwill cause the roller 88 to ride against the cam face of the plate 81 secured to the lock bolt, thereby forcing the lock bolt to the left and unlocking the door by disengagement of the lock bolt from the lock strike 1l. Therefore this position of the master or gang bar ensures complete of Figures 7 and 8 will not act on the llock bo1t,

that is, will not move the lock bolt to the left or unlocking position, but on the contrary, the lock bolt will be left in the projected or locked condition, so that the cell door will not be unlocked.

even by complete traverse of the master or gang Under such conditions, therefore, it is possible to unlock the other cell doors, either by key When in this position the wedge or gang operations, leaving the door of the cell in question still locked. This makes it possible to isolate selected prisoners, leaving them locked in their cells, as for example when they are being subjected to special punishment or other treatment.

It is to be noted that no special form of mechanism is needed for moving the master or gang bar back and forth, and therefore I have not herein made particular disclosure of the construction of the devices contained within the control box 21.

While I have herein shown and described only a single form of structures and devices still I do not intend to limit myself thereto, except as I may do so in the claims to follow.
