Application filed. May 5, 1919.

To all to 710m it may concern Be it known that I, BYRON EAnTHoLoMnw, a citizen of the United States, and resident of Joliet, county oflVill, and State of Illinois, have invented certain new and useful improvements in Locking Systems, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to a locking system, and has been developed with special reference to a locking system for jails.

in object of the invention is the provision of a jail wherein each of the cells may be locked from a central station. A further object is the provision of a jail wherein each of the cells may be locked from a central station, from which station the interior of each cell may be seen. A further object is the provision of a jail in which the cells may be locked individually or simultaneously in selected groups from a central station. A further object is the provision of a locking system for jails wherein each cell may be locked from a central station or by a key applied at the cell itself, if preferred.

A. further object is the provision .of a system by which the cells may be locked from a central station either singly or in multiple by power-operated means. A further object is the provision of a locking system in which the cells may be locked from a central station, and wherein the improper actuation of any lock will be indicated at said central station.

Further objects and the features of the invention will appear from the description when read in connection with the accompanying drawings forming a part of the specification, wherein Figure 1 is a vertical section through the jail as a whole;

Fig. 12 is a detail perspective view of a portion of the lock mechanism. The jail building as a whole is shown at 15. As illustrated in Figs. 1 and 2, the cells 16 of the jail are arranged about the exterior of a building shown as circular, but which may equally well be polygonal, and are arranged as shown in four tiers. Access to the balconies 17, from which the cells are entered, is had by means of the staircase 18, arranged at the side of and 0 er the entrance doorway 19. The central station occupied by the guards, and from which the locks are controlled, may preferably be entered by a subway, indicated in dotted lines on Fig. 2 of the drawings by reference character 20. The floor 22 of the guardroom is reached by means of a ladder (not shown) and a central opening 21. In this guardroom there is a table 23, spaced away from the walls 24- thereof, and it is upon and within the structure of this table that my central lock-controlling means are disposed.

The door of each cell is made to slide, as shown in Fig. 5, in which the door 25 is shown as sliding upon rollers 26 and as bearing upon its edge catches 27. These catches are adapted to pass through slots 28 in the door jamb 30, to be locked by means of the jump bar 29, sliding into the catches. The jump bar 29 is shown in Fig. 6 as bearing two

projections

31 and 32, either of which is adapted to cause movements of the jump bar, the former by means of a key and the caused by pressure upon the shoulder 41, and

latter by means of power transmitted from the central station.

The power from the central station is applied through jump bar operating rods 33. T 0 cause movement of these rods a system of bodily movable mechanical means radiating from the central station is provided. As shown in Fig. 1 this system consists of bell cranks 3st and 3 5, connecting roc 36, and main rod 37, leading downward from the guard station. The system mentioned, with rods 33 and the means for actuation described below, thus constitute means for distant control and actuation of the cell locks.

The mechanism for controlling the motions of main rods 3'? is illustrated in Figs. 3 and. l. Movement upward of rod 3'? is, by means of the bell-cranks and connection, transmitted into movement downward of the jump bar operating rods 38 and therefore causes the jump bar to enter the catches 27 and lock the cells. Each rod 87 is shown in Figs. 3 and l as bearing three sleeves 38, set and as. Sleeve 38, which will be called the rod sleeve, partakes of all vertical movements of the red but may be rotated upon the rod to a limited extent because of its connection to the rod by means of the pin 39, fixed in the rod projecting into the circumferential slot 40 in the sleeve. Tear the lower end of the sleeve 38-there is an annular shoulder, shown more clearly in Fig. el, at 41, and above this shoulder a. pin 42 (Fig. 3) projects from this sleeve. Downward movement of the rod sleeve, and therefore the rod,

applied, bv means of shoulder or collar l3, upon the sleeve er, which will be called the intermediate sleeve, which in turn is pressed upon by shoulder or collar 45 upon sleeve 46, which sleeve will be referred to as the power sleeve.

, l'v lovenients upward of rod sleeve 38 will be caused by pressure against pin 42 applied by means of the upper shoulder or collar 4:7 upon the intermediate sleeve a l, which in turn is .essed upward by pressure of spring 1 8, which pressure is applied by means of the shoulder or collar l9 upon the upper end of the power sleeve 4:6. Thus, pressure downward'upon the rod will be positive at this point, but pressure upwai d, which it will be remembered is the direction of motion when the cell is to be locked, is applied through the spring B, and is therefore a yielding pressure.

The lower end of the rod 37 slides in an eye 52, formed on the horizontal arm of the bell-crank 35, and actuates the crank through the medium of a helical spring- 50, sleeved uponthe rod and interposed between the eye 52 and acollar 51 on the rod. Therefore, when thebell-crank, through any defect in operation, resists the pressure of the spring sufliciently to allow compression of the spring, the lower end of the main rod, which, as shown, is provided with a T head 53, may continue to move downward without injury to the mechanism.

Power is applied to the power sleeve 16 through sleeve lug 54 and connections, which will be described hereafter. To preserve the rotational alinement of intermediate sleeve it with the other two sleeves, the power sleeve is provided with an instanding pin 55, which plays within a longitudinal slot 56 in the intermediate sleeve. hen the rod sleeve 38 is rotated about the rod so that pin l2 registers with slot 56, upward motion of r the power sleeve 46, transmitting motion to intermediate sleeve 4A, will fail to all'ect the rod sleeve and the main rod. Therefore,

when in operating any group of main rods;

simultaneously by the power-operating means it is desired to leave one of the group unaffected, the rod sleeve of that red may be rotated until pin l2 comes into aline'ment with the slot as described. lVhen this'opera tion is carried out this main rod would then drop and unlock the corresponding cell, it not preventedfrom doing so. To keep control of such rod there'is shown'a latch 57, pivoted upon a plate 58, which plate is made adjustable upon the covering plate 59 of the table 23 upon which the'rods are mounted. This latch '57 is pressed towardthe rod by means of'spring 60, and the adjustable plate 58 is provided'that the latch may be adj Listed so as to register with and engage one of a series ofjslots 61' provided on the rod-sleeve. li hen the rod turned the slot 61 will catch upon the latch 57 and therefore keep control of the rod. I

Preferably the locks are controlled in groups or in multiple, each group comprising: one-half of the cells upon each floor. The four rods, shown in Fig. 3, are designed to be connected to the four cells arranged vertically in a tier, one on each gallery. To this end the power-operating means is connected to every fourth one of these rods, and by means of four motors 62. each cell upon each. floor of one-half of the jail" will be controlled. To connect the. sleeve lugs 5 1 with the power there are shown bars '68, one for each panel operated by leach motor. These bars are'connected to the sleeve lug through the intermediary ofconnectors 64-. 7

screws revolved through worm gear mechanism 66, operated by means of -motors 62.

- Since the table 23, upon which the lockcontrolling mechanism is placed, is polygonal and I desire to operate rods on more than one side of the table by a single set of motors, I have devised the arrangement shown in Fig. 9, in which are shown operating shafts 85. To transmit the motion of the shafts around the corners I have provided universal joints 86, and I prefer to provide each shaft 85 with two sets of Worm gearing 66, whereby each end of each bar 63 upon each panel of the table will be simultaneously operated.

It may be desirable to operate any individual cell from the central station manually. To this end I have provided means for attachment of a detachable lever 87, illustrated-in Fig. 4. This lever is in the nature of a toggle, and one end of the toggle will be applied to a stud 88 upon the upper shoulder of the intermediate sleeve, and the other end to stud 89 upon the rod sleeve. When the rod sleeve is rotated by pulling on the handle of the lever so as to bring pin 42 in line with slot. 56, and latch 57 is entered into lower slot 61, by pressing down upon the end of the lever 87 the weight will be taken off from latch 57, which may be withdrawn from the slot :by hand. Then by pushing the rod down under the control of the detachable lever, the cell may be unlocked and the rod may be retained in any adjusted'posi tion by means of the various slots 61, illustrated in connection with latch 57. While thismanual operation of any rod is going forward, or while the rod isin any adjusted position as referred to, the in termediate and power sleeves ofrthat rod are free to move in unison with the other sleeves of their group, in response to operation of its motor, by coaction of slot 56 and pin 42.

In the event that any lock becomes jammed or fails to work properly, the only result will be extra pressure placed upon spring 48. In the event that a cell door is not closed jump bar 29 will not enter the recess in catch-27, and will continue to lower during the entire 'motion of'thepower sleeve. This excess movement of the jump bar will be evidenced at the central station by the corresponding rod 37 rising, above the remainder of the rods, and will therefore serve as an index to show that the cell in question is not properly locked.

For an adjustment of lengths of the main rods 1 have illustrated turn buckles 91, shown in Fig. 3. The upper ends of the rods are shown square so as to be more readily guided in frame member 92. and each rod is illustrated as bearing a projection 93 at right angles to its upper extreme, which projection is perforated. I have shown a cutout switch at 82 which, in its open position,

bar 37, as described, the bar 37 cannot be moved, nor can the group of which it is a member be operated in multiple by power from its motor 62.

The cell door 25, in Fig. 5, has a bar 96 projecting from one side of the top thereof, and such bar is provided with ratchet teeth 97. Pawl 98 is pivoted above this bar and is pressed toward the bar by means of spring 99. 1 7

Projection 125 extends from pawl 98 into the pathof movement of T-head 126 on jump bar 29. When the jump bar is at the upper limit of its movement the T-head will, by lifting projection 125, hold the pawl out of contact with the ratchet teeth and the door will be free to open. VVhen the jump bar is raised to a position wherein thesame will just clear catches 27, the T-head will not contact with projection 125 and the door may be closed freely but cannot be moved in an opening direction because of the pawl and ratchet. This middle position istheposition to which the jump bars are moved when the prisoners are to go into their cells. Aseach prisoner goes into his cell he is re quired to close his own door after him; 'lVith the jump bars in the middle position he will be unable to open the door again, whether he completely closes the same or not. Failure to. completely close the door to bring the catches 28 into position for engagement with the jump bar when the same is lowered will be indicated at the central station by undue motion of the main rod, as explained above.

7 The central station control of jump bar 29 is through projection 32 and jump bar operating rod 33, as already described. The connection between these two parts is by means of a sliding bolt 100, Fig. 6. This bolt slides in the hollow slotted end of projection 32, and is provided with a pin 101 controlling its movement and rigid with the bolt. When rod 33 and projection 32 travel vertically as aunit, pin 101 travels therewith in slot 102 in the T-head of a bar 103, shown in detail in Fig. 11. This bar is shown as mounted to slide horizontally in guides 123 and a strap 12 1 over the free end thereof. Therefore sliding movement of bar 103 will shoot bolt 100 by pressing upon pin 101 so as to withdraw the same-from or engage the same with the opening in bar 33 and thereby connect or disconnect the central operating mechanism with the jump bar.

Key-operated means for actuating the lock of each cell individually may be employed. This key-actuated means comprises a rotatable member 104:, having a key-receiving slot or opening having gear teeth on 'its i'e dg e, and a'sleeve 105 caused to rotate by coaction of gearteeth-106-with the gear teeth upon member 104.-

. Sleeve 105, freely rotating on stub shaft 105f,:carries four elements, viz z first, a single toothed member 107located near the back part of'the compartment in which the lock is placed, the function of which is to shoot the 4 bolt 103 by coaction of its tooth with depression"108therein. v Z

Thesecond'instrumenta'lity upon the sleeve fl05 is a c'am member 109. The function of "thiscam is to operate the

togglearms

110 and 111. These arms are spring-pressed'toward the leftas by spring -148, as seen .in

The motion of the toggle after contact'with the'lug 'ismerely sufficient to take the pressure ofjump baroperating rod 33 offfrompin 100,'so as to allow the shoot- 30 The fourth element is the segmental gear 116. The function'of this segmental gear is, 40

by coaction with rack teeth 117 upon projection 3'1-,'to raise thejump bar 29 andv thereby free it from the catches 27.

The operation of the mechanismjust described *is'. as follows :',The initial movementv of the sleeve 105 will cause the motion of pin 113 tothe right, bringing the end of arm 111 in contact with lug 114 and lifting rod 33 slightly before tooth 107 comes into register with depression 108. Tooth 107 will coact with depression 108 so as to withdraw bolt 100 from rod 33 before segmentalgearing 116 takes into rack teeth 117 Therefore, when the segment and rack teeth come inte action there will be nothing toprevent the action ofa key, not shown, applied to keyhole 151 from lifting the jump bar 29.

jToggle'arins Y110 .and 111 arepivoted to a projection 118, shown in Fig. 6, tospace the same away from the back of the lock cavity a proper distance.

The View of Fig. 81s, as descr1bed,.asect'1on looking 1n both. directions from line' of Fig. 3. However, vin Fig. 8- the; upper end or extension 67'is shown in full lines-but in different positions ineach half.v iAs Ishown in Figs.

3 and 4, a casing is placed over, .theend of eXt ensi0n67 and rests on table '92 This "casing lcontainsthev control mechanism, and

projecting from it are .push buttons 1.69, 70, 71' and-'72 pressed outwardly by springs ,7 3.

- The structure of the circuit-closing mechanism operated by the vpush buttons is clearly illustrated in Fig.8, where sliding plate 74 is shown as guided in .ways75. L-shaped deans 751s pivotedto plate 74,

as at 77, and; is spring-pressed against stop 7 8 by springl7 9 when not preventedby contact of the short arm of the detent with projec'tion 80, i which 1 projection is rigidly secured to the casingl Each sliding plate also carries two circuit-closing. elements, as 81,

82, coacting with contactsf8 3" and 584. EX-

tension 67 of connector 6.4 carries lugs which 7 project so thattheirpath of movement will bring them. into engagement with an L- shaped arm on the corresponding side of the extension if the same have its push buttons depressed.

The normal os tion transferee closer with the, circuit open is shownat the left and upper right of Fig. 8. From this positionif the button be pressed against resistance of spring 73'to the position of the stop 7 8. Pressure b'eing removed from the push button the endof the 'shortjarm of the 'detent lying against theend of projection 80 will hold the slidingplate in the advanced position'with end 129-111 the path of movement of the

corresponding lug

127 or 128..

" 'Withex tension 67 in the positionjsho'wn at the right of Fig. 8, the jump bar is 'down and the cells are locked. When button 7 2 is pressed as shown in that figure a circuit will be closed as follows: from the source of energy through wire .129, armature 130,

1 lower right portionofFigp8, detent .7 6 will be removed'from, projection 80, and by .infi-u'ence of spring79 will be pressed against wires 131, 132, .cont acts'83 and81,wire 135,

136, to, thesource of energy." There is also a path from contact 81 through

wires

137, 138,;[ie'ld windings 139, wir es 140, 141, .conta'c'ts84'and 82, wires 142, 136, to the source of energy. It will be noted that as described the current through the field flows also through the armature and hence the motors used are series Wound.

The motors are connected in such a manner that the current just traced will cause the motor to move extension 67 downwardly and the jump bar upwardly until at the lowest desired position of the extension lug 127 will impinge upon end 129 of the detent, thus raising the short arm thereof out of its position against projection 80, when spring 7 3 will retract the mechanism, open the circuit and stop the motor.

Ifnow button 69 be pressed a circuit will be closed as follows: wire 129, armature 1'30, wires 131, 143, 144, contacts 81, 83, wires 145, 136, to the source of energy. Also a circuit from contact 81 through wires 146, 140, to the field winding 139,

wires

147, 148,

contacts

84 and 82,

wires

149, 129 to the source of energy. It will be seen that the circuit just traced passed in the same direction through the armature, but in the opposite direction through the field from the circuit closed by button 72, and hence the mo tor would be operated in the opposite direction.

' Since the contacts actuated by button 71 and 72 are wired in parallel, as are those actuated by

buttons

69 and 70, buttons 69 and 7 Owi-ll cause a motor to revolve in one direction and 71 and 72 in the opposite direction. Also the detents 76 and projection 80 for

buttons

69 and 70 are inverted, as compared with those of 71 and 72, and hence will serve to stop the motor upon upward travel of extension 67 through action of lug 128, in the same manner as the mechanism of buttons 71 and 72 will stop the motor on downward travel of the extension througlr action of lug 127.

The normal routine of actuation of the mechanism would be; from full locked position with 67 at its highest point to full un locked by use of button 72; from this position with the cell doors left open to middle position by use of button 70, (this places the ratchet mechanism of the doors in operative position so that any door may be shut and caught, though not locked by the jump bar) and from this middle position to full locked by use of button 69.

In the event that button 69 has been operated while the cell doors are open for any reason, the middle position of the jump bar may be reached at once' by use of button 71;

In the claims I have referred to control and actuation of the lock. By control I wish to be understood to refer to not only actuation but to the maintaining of the lock in any position to which it has been actuated. In other words, control is intended to refer to causing movement or preventing movement, while by actuation I wish to be understood as meaning the causing of movement of the locks to either lock or unlock the cells.

Also in the claims where the expression locking the cells is used it is to be understood as referring to fastening the closure of any means ofegress from or ingress to the cells whether the means be a door, window, port hole or any other opening.
