JAIL-noon LOCK Ann ornnnrrne lrncnnnrsn Application filed November 6, 1909. Serial No. 526,526..

To all whom it may concern:

Be it known 'thatI, FOLGER ADAM, a citizen of the United States, residing at J oliet. in the county of Will and State of Illinois, have invented a -new and useful Improvement in Jail Door Locks and Operating Mechanism,

of which the following. is a specification.

This invention relates to improvements in gang locks for sliding cell doors and has for one of its objects the provision of a gang lock, adapted when thrown in one of its ,positions, to permit the simultaneous locking of all of the closed doors of a row of cells and When thrown in another position to unlock the same;

A further object of the invention consists in'the provislon of a gang lock constructed and arranged so that-when it is unlocked in one of its'positions all of the doors of the row of cells will be locked,

but may be independently unlocked by separate door locking devlces, with which each dooris provided, and which locking devices are operatively connected with the gang look. In the most improved embodiment of my invention the separate locking devices for each door are normally engaged therewith to lock the same and when the doors are unlocked by the gang lock the separate door locking devices are operated by the gang look. I

A further object of this invention is to provideveach of the separate" door locking devices with means for dead locking any one or more of the doors whereby such doors cannot be opened by the gang lock, or by thedoor locking mechanism proper, the arrangement being such that the dead look-- ing of one or more doors does not in any way interfere with the simultaneous locking or unlocking of the remaining doors by the v gang lock.

The invention also contemplates a gang operating device or mechanism for the doors arranged and designed to open and close all of the doors in unison, the feature of novelty, of which consists, in the operative connection of'the gang operating device with the gang lock, and separate locking devices, so that all of the doors which are under control of the gang lock will be throwninto operative relation with the gang operating device to be opened simultaneously and so that those doors which are f dead locked f or those. doors which are not in operative adjustment with the gang lock, and are in adjustment to be opened only by the separate locking devices, may be opened or closed and locked wholly independently of the gang operating device.

Patented Nov. 5,1912.

The invention includes other features 'of novelty and details of construction which willbe more fully described in connection with the accompanying drawings and which will be more particularly pointed out and ascertained in and by the appended claims.

In the drawings: Figure 1 is a front elevation of one end of a tier showing one comnlete cell and a portion ofan adjoining cell with parts broken away to show the operative mechanism. Fig. 2 is a similar view ofa portion of the structure shown in" Fig. 1 on an enlarged scale; Fig. 3 isan end elevation of the structure Shown in Fig. 2 looking in the direction of the arrow 3 thereof. Fig. 4 is a fragmentary sectional view of the gang lock and one door lock showing the gang lock in a final locking position wherein all. of the doors' are 'locked and wherein none of the doors can beopened or unlocked by theirrespective door locks. Fig. 5' is a similar view with the gang lock in an intervening position. and with all of the doors of the cells locked but in. an adjustment wherein any one of the' cell doors can be unlocked by operation of their respective door locks. Fig. 6 is a similarview with the gang lock in an unlhcking position showing an adjustment wherein all of the doors'are unlocked and may be simultaneousl'y opened by the gang operating mechanism. Fig. 7 is a similar view illustrating the gang lock in a final position and one door lock in a dead locking position in which position its respective door is locked and will remain locked irrespective of the position ofthe gang lock. being impossible to unlock the door from the lock proper and only possible to unlock the door by readjustment of the dead locking means. a view similar to Fig. 2 showing the door opened by the gang operating device. Fig. 9 is a detached plan view of a portion of the gang operating device. Fig. 10 is a view in elevation of a door locking bar. Fig.

Fig. 8 1s '11 is a view in elevation of a gang doorlocking bar. Fig. 12 is a view of a controlling lever for operating the gang lock looking'in a reverse direction from the bars as they appear in Fig. 2. Fig. 13 is a view of one of the gang locking bars showing the same in its difierent operating positions. Fig. 14 is a view similar to Fig. 5 with the locking mechanism in a position to permit the jail door to be opened. Figs. 15, 16 and 17 are enlarged detail views of the individual locking mechanism.

Like numerals of reference designate similar parts throughout the different figures of the drawings.

Referring specifically to the construction shown, 1, designates doors mounted upon rollers 2, adapted to run upon a suitably formed railor track 3, to afiord requisite sliding movement of the door abreast of the door way. The door is provided with a locking member which is preferably in the form of a rigid notched member 4 having notches 5 and 6. Above and below the members 4, each doorjs provided with notched lugs 7, preferably rigidly secured to the doors, the notches 8 thereof being in vertical alinement with the notches 6 of the members 4. Each door is provided with an independent lock indicated as a whole at 9, and with which the member 4 of the respective door cooperates. An -abutment or jamb strip 10 is disposed on one side of each doorway to receive the impact of the doors when closing and said strips are provided with suitable notches 11 and 12 for permitting passage of the member 4 and lugs 7, respectively.

Lying back of each jamb" strip 10, or on that side opposite to the side against which the door engages, are two locking bars, one of which is directly connected with and forms a part of the gang lock, and the other of which is connected with the first mentioned bar indirectly preferably through the door locks, and which may be operated by the gang lock, or the door lock, or which may not be operated byeither when the door lock is in a deadlocking position. One of said bars being adapted to act on an individual door lock when thrown out of operative relation with the gang lock.

The gang locking bars are indicated at 13 and are provided with engaging portions preferably in the form of

elongated slots

14 and 15, the slots 14 being adapted for engagement with the notches 6 of the members 4 and the slots 15 being adapted for engagement withthe notches 8 of the lugs 7. The bars 13 are operatively connected with a gang shaft 16, conveniently arranged above each tier of doors and extending throughout the length thereof.

The operative connection between the bars 13 and the shaft 16 may consist of eccentrics 17, rigidly secured to the shaft 16,

and eccentric straps 18 suitably secured, or

if desired formed integral, with the bars 13. The gang shaft 16 may be polygonal in cross section to facilitate non-rotative engagement of the eccentrics thereto, as clearly shown in Fig. 13.

A device is provided for operating the gang shaft 16 and, as shown, said device,

consists of a lever 19, pivotally mounted at 20, upona notched quadrant 21, secured in any desirable manner to the structure. Said lever is provided with a common form of manually operable sliding dog 22, adapted for engagement with

notches

23, 24 and 25 of the quadrant 21 to lock the lever 19 in three different positions of adjustment. The

lever19 is provided with a pin 26 having 'slidin engagement with a slotted projection 2 of a rack bar 28, which is mounted to be reciprocated vertically in a lower guide 29 and an upper guide 30. I A rack 31 is provided on the upper end of said bar 28 and engages the pinion 32 on the gang shaft 16. It will be obvious from the foregoing that as the lever 19 is shifted,"from' one position to the other, movement will be imparted to the gang shaft 16 and to the gang locking bars 13 to adjust the latter to desired positions.

The locking bars 33 lie abreast of and in abutting relation with the gang locking bars 13 and are provided with engaging portions preferably in the form of

slots

34 and 35, slots 34 engaging the notched portion 6 ofthe locking members 4 and slots 35 engaging the notches 8 of the lugs 7.

The construction of the independent door locks will next be described in detail.

Each lock includes a casing 36 provided with a bolt guiding pin 37 and a guiding socket 38 arranged in vertically alined relation. A bolt 39 is apertured at 40 to receive the pin 37 and .is provided with a shank 41 disposed in the socket 38. A bolt spring 42 is interposed between the upper ends of the same and a shoulder 43, formed in the easing, to normally hold the bolt 39 in the posi; tion shown in Fig. 4. The lower end of the bolt39 is recessed at 44 to permit the end of the member 4 to project therein and the bolt is provided with a latch member 45 adapted for engagement with the notch 5. The front face 46 of they latch portion 45 presents an inclined face to the end of the in mber 4 so tl at when the member 4 is thin t into the position shown in Fig. 4. the bolt39- will be automatically raised and subsequently lowered, by the spring, into engagement with the member 4. A key post 47 is revolubly mounted in the casing 36 and is provided with a slotted portion 48 to receive a suitably formed key. The lower end of the key post is provided with a lug 49 adapted for v engagement with a bolt actuating plate slidably mounted in the casing 36. As- Shown the bolt actuating plate 50 is slottedla't 51,

and a pin 52, mounted on casing 36, projects therethrough to guide the lower end of said plate. The upper end of said pla te'slides between two lugs 53. The plate 50 is provided with an extension 54 engaging a lug 55 which serves toraise the bolt 39 when the plate 56 are pivotally mounted onthe stationary pin 52 and said wards project into a suitable recess in the key the key and mounting 52, r

formed'notches 58 provided with shoulders 59, in the wards 56. This engagement of the wards 56 with the post 57, which is normally maintained by the spring 60, renders impossible the upward or downward move ment of the plate 50by any but the properly formed key. When the proper key-is applied to the lock thewards 56. are freed from the post 57 and the plate 50 is free to beoperated by the lug 49 against the lug 55 to raise the same and the bolt 39 0f whichit is" apart. When the bolt 39 is free from gang and deadlock control, as shown in Fig. 7, the upward movement of the plate 50 is adapted to raise the bolt 39 to the position shown in Fig. 6, against the pressure of the spring 43, which spring also serves to return the bolt 39 and the plate 50, upon'the release of pressure on the key, to their original position as shown in Fig. 4, Where any further downward movement ofthe plate 50 is prevented by the top of the slot 51 coming. to rest upon the pin 52 which, as'has been staltged, is integral with the casing 36 of the loc The parts hereinbefore described constitute what will hereinafter be termed the door lock proper and the ,function of the same is to permit the attendant to unlock any one of the cell doors which may be thrown out of relation wit the gang-lock.

The relation which th lock mechanism proper has with the gang'lock will next be described in detail;

A projection 60, carried by the bolt 39,

has operative connection with the gang look mg bars 13, and the locking bars 33, and

performs the further function of operatively connecting said bars with each other. As

shown, said projection 60 is in the form of a rod which engages an aperture 61 in the locking bar 33, and aslot 62 in the gang locking bar 13.. It will he noted that the slots 15 are of greater length than the slots 35, and that the slots 14 are'of greater length than the slots 34, and that the slot 62 is sufiiciently elongated with respect to the aperture 61 to correspond with the -extra length of the

slots

14 and 15. The extra play afforded the gang locking bars 13 permits the 50 is actuated. A .plurality of Wards post 47 to be' engaged shifted upon their pivotal ward post 57 is mounted. ,upon the plate 50 and engages suitably tion or rod, 60. Wh

same to be raised out of locking "relation .with the members 4 and the lugs 7 whenthe S wung from the notch 23 to thenotch'24, which is theposition shown in Fig. 5, without releasing the locking bars 33 from theunembers 4 or lugs 7. This is the neutral or intermediate position or adjust, ment of the gang lock which does not unlock permits any one or more In this position each bar 33:may be, con 'sidered an independent. door lock with means, which may be the door lock,-for actuating thebar to unlock the door. It Will be readily understood that in the position shown in Fig. 5 the raising of. a bolt 39, by a key, will also serve to raiseajcorrespondlng bar 3.3 and'releasethevlugs' 7 therefrom; as

well as the correspondin member .4 there from, the bolt 39 acting t trough the rojecen the gang ock is thrown from'alock-ingto an unlocking position to unlock all of the doors simultaneously, then the lever 19 is thrown from the notch 23 to the. notch 25, carrying all of the bars 13a sufiicient distance u disengage said bars from t members! and'subsequent-ly act through engagement of the lower ends of the slot- 62, W1 11 the projectionGO, to carry the bars 33 up rdly a suflicient distance to disengage the same rom the members 4 and lugs 7, which movem ntfwill .also carry the bolts 39 up? wardly a suflicient distance to disengage thelatch members 45 from the members 4. 7 It will thus be seen that when the gang lock is thrown intoan unlocking position both

bars

33 and 13 form a part of the gang lock and 1" that said bars are operatively connected with each other, and with the independent l0cking devices proper. It will be further noted that the projection 60 constitutes means performing a distinct function of operatively connecting the

bars

13 and 33 with each other and a separate distinct function of operatively connecting the independent locking devicesproper with the gang lock,

It is sometimes desirable to dead lock one or. more of the doors of a row of cells so that it cannot be opened by the gang lock, or by the lock proper, and this feature of the invention will now be described in detail.

As shown the dead lock. device comprises a key post 63 having a key slot 64 and a lug 65. A ward plate 66 is slotted to receive a stationary pin 67 and is guided between 1ugs 6 8 when actuated by the key. A

gang locking mechai wardly to first e lugs 7 and actuated by a properly plurality of wards 69 are pivotally mounted 69. Springs 73 normally hold the wards 69' in engagement with the post 70. Whenthe plate 66 is in the'pos'ition shown in Fig. 4

one end of the slot in'the plate-66 'isf inengagement with the pin 67 and the shoulders with the post 70. and

7 2 are in engagement theplate 66 is thereby held in the position shown. In retracting the plate 66, from the position shown 'in Fig. 4:, totheposition shown in Fig. jlocking or preventing action of the lock proper when the dead lock is in an active shown in Fig. 7, the key post 63 is turned to the left and the post 70 is brought into engagement with the notches 71 thereby holding the plate 66 in'a retracted position. The projection or rod 60 is preferably slidably mounted in the bolt 39 and is provided -with an elongated loopextension 74 which engages a lug 75 on the plate 66. It will be.

noted that this looped eXtension74 provides a lost motlon connection between the dead lock and the lock proper permitting the lock proper ;to be freely operated in any mannerwithin th e limits of its action when the deadlockiis in a neutral position, as 4. Means are provided for position '(Fig'. 7) and as illustrated, said means includes a lug 76 preferably disposed upon'the outer or front wall of the lock casing 36 and positioned thereon in such a manher as to. permit the loop 74 to reciprocate freely on the right hand side of the lug 7 6 when the dead lock is in a neutral position. It will'be further noted that this lug 76' prevents the dead look from being ,thrown, from a neutral to an active position, except when. the bolt 39 and loop 74 are in a lowermost position, see Fig. 6, in

view of the fact that the loop 74 would engage the lug76, laterally, and prevent the plate 66 from being thrown into a retracted position. It will also be noted that when the bolt 39 is in a lowermost ;position, as shown in Fig. 7, and the dead lock is thrown from 'a neutral to an active position, the loop 74 is shifted abreast of the lower end of the lug 76 so that the bolt 39 cannot be raised by either thekey of the lockproper .As' a further means of preventing the gang look from operating the lock proper when the dead lock is in an active position the rod or movement of the plate 66 to throw the dead look from a neutral to an active position will withdraw said projection 60' from engagement with the slot 62, therebv disconnecting the

bars

13 and 33 from each projection 60' is of such length that the laterally shifting other and preventing any movement of the bar 33 of the dead locked door under the action of the gang look. It will thus be seen that when the door is dead locked it is secured-by its bolt 39 and bar 33 engaging the member 4 and also by the bar 33 engaging both'of the lugs ,7 thereby securely holding the door locked.

"Reference will next be made to a gang door operating device the novel features ofwhich consist in its operative'connection with the locking mechanisms.

As shown, a gang operating bar 76 extends throughout the length of a row of cells and is preferably disposed above the doors thereof. Any form of-suit-able bearings may be provided for the bar 7 6 to permit of longitudinal shifting movement thereof. The bar 76, as shown, is operated at one end of a row of cells by a device which may comprisethe following elements: A link 77 is pivotally connected to the bar 76', at 78', and at its opposite end said link 77 is connecte with a lever 78, at 79, and said lever 78 is pivotally mounted at 80, to a suitable bracket 81, secured-to the structure in "any desirable manner; The lower end of the lever 78 is slotted at 82 and is connected with a manually operable lever 83, which is pivotallymounted at 84', to a bracket 85, and is connected with the lever 78, at 86, the

:slot 82 affording requisite movement of the connection 86 when the lever is shifting from the position shown in Fig. 2, to the position shown in Fig. 8, and vice versa, as will be obvious from the drawing. In the form shown, each door is connected at 87, with one end of a lazytong structure 8 8, the other end of which is connected at 89 with any desirable stationary part, as 90.

Intermediate of its ends the lazytong structure 88 is connected at 91 with a member 92, which is in the form of an arm, and which is designed to be normally out of operative connection with'the gang operating device, when the doors are locked, either by the door looks or gang locks, all of said bars being adapted to be simultaneously thrown into operative relation with the gang operating-device when all the doors are unlocked, by the gang lock, or as many of the doors as may be unlocked by the gang lock. The members 92 of those doors which are not unlocked by the gang lock, or which may be dead locked are not thrown into operative relation'with the gang operating device. Furthermore after a certain number of doors have been unlocked by the gang lock and opened by the gang operating device those doors remaining closed may be subsequently opened by unlocking the independent locks and the locking bars 33 of such door or doors will not interfere with the gang operating mechanism. Referring to the specific construction shown, each member 92 is connected with a locking bar 33, at 93, a suitable slotted flportion 94 ment of any one of the members 92 ofthose doors not under control of the gang operating device and not opened by the gang lock and which are subsequently opened after the doors,. under .control of the gang operating gang lock devices, have been opened, it being noted that at such time the studs 95 will have been shifted to the right before the dead lock or subsequently opened doors have been opened, thereby shifting the studs into the position shown in dotted lines in Fig. 9. It will be noted that a door will only be thrown into operativerelation with the gang operating device when its respective bar 33 has been shifted upwardly throughout its extreme unlocking position so as'to bring the notch 94 into engagement with the stud 95. When the gang lock is adjusted to. a neutral position, as shown in Fig. 5, the bars 33 will not have been moved and the doors will not be thrown'into operative relation with the gang operating device. When however the gang lock has been thrown into an unlocking position, as shown in Fig. 6, all of, the bars 33, under control of the gang lock, will be shifted upwardly a sufficient distance to engage the members 92 with the studs 95. .Assuming that the gang lock is in a neutral position, as shown in Fig. 5, with all of the doors closedand with the gang operat-' ing device in a closing position, as shown in Fig. 2, any one of the doors may be opened by its individual look without throwing such v door in operative relation with the gang dein the position vice. To afford this advantage the parts are so proportioned, and the upper portions of the notches 5 and 6 of the member 4, and the notches 8 of the lugs 7, are reduced in heightso that the lugs 7 and member 4 of the door to be opened may be released from engagement with the bar 33 and the. bolt 39 without'raising either a distance equal to the distance to which they'are raised when operated by the gang lock. With the parts set forth in the foregoing, a key may be inserted in the key post 47 of the door to be opened and the bolt 39 and bar 33 will be raised a suflicient-distance to clear the upper reduced tops of the notches to free the member 4 and lugs 7 butthis upward movement of the bar 33 will not be son of the fact that of the row have sufficient to engage the notch 94 with the pin 95, see Fig. 2, therefore the attendant can slide the door free to trol. l

1 While the operation of my invention will be clear from the foregoing an understanding thereof may be facilitated by a short recapitulation.

- With the lever 19 in the final locking position, as shown in Fi 4 all of the

bars

33 and 13 will be in-loc ing engagement with the locking members and lugs of all the doors and all of open-independently of the gang conby their individual locks proper, namely the bolts '39. In this position all of the members 92 will be out'of connection with the gang bar 76, and it will be absolutely impossible to unlock any of the doors by the individual door locks because the gang lock will hold the bars 13 in a full locking position thereby preventing the pins and bolts 39 from being raised. tion, however, nothing will prevent any one of the doors from being dead locked because the loop 74 are below the lugs 76 and the dead locking device can be readily turned to withdraw the pin 60 from engagement with the slot 62, thereby throwing such individual lock out of relation with the ang lock and preventing the bolt 39 from eing operated by the key post, 47, by reathe loop 74 is beneath the lug 76. It will thus be seen that if it is secretly decided at a late hour to prevent the release of a prisoner in a certain cell on the following morning said cell can be dead locked after all of the other cells been finally locked and that when all of the other cells have subsequently been unlocked by the gang lock the dead locked cell will still remain dead locked. If it should be'desired to open any one of the doors of a row of cells and maintain all of the other doors of the cells of this row locked then the lever 19will be thrown into a neutral position with the gagement with the'slot 24'; This movement rotates the gang shaft 16 and lifts all of the bars 13 out of locking engagement with the members 4 and lugs 7 of all the doors thereby temporarily throwing all of the doors out of control of the gang lock. From Fig. 5'it will be seen that this neutral position does not lift the bars 33, and does not lift the-bolts 39, therefore all of the doors are individually locked b the bolts 39 and bars 33. By inserting a ey in the post 47, of the door desired to be 39 and bar 33 may be lifted a suflicientdistance to free the member 4 and lugs 7 and permitthe .door tobe opened. As, herein before described this movement will not be suflicient to cause the bar 33 to'engage the open and the door will be,

the locking members of allot the doors will be additionally locked In this posidog 22 in em opened, the bolt member 92 with stud 95. It will also be noted that when the gang lockis ina neutral positionnone of the bolts 39 are raised,

therefore any one of the doors of the cells may be deadlocked. Ifitis-de'sired to unlock all of the doors of a row of cells by the gang lock the lever 19 will be raised to the unlocking position shown in Fig. 6'

with the dog 22 of thelever 19 engaging the notch 25, in which position, the lower ends ofthe slots 62 will engage the rods 60 and raise all of the bars 33 and bolts 39, except for such doors as'have been dead locked.

by withdrawing their respective pin or pins 60 from engagement with the slot 62. This movement imparted to the bars 33 will be greaterthan the movement imparted thereto when doors 'are unlocked separately and will be sufficiently great to engage all of the notches 94 in the members 92 with the studs ;95 and place all of the doors, not dead locked, into operative relation with the gang operating device. By now throwing the gang operating'lever 83 from the position shown 1n ,Fig. 2-to the position shown in Fig. 8 all of the doors, connected with the gang operatingdevice may be simultaneously opened and subsequently simultaneo'usly closed.
