PETER J'. PAULY, 0F ST. LOUIS, MISSOURI.

v"TAIL-IDOOR-LOCKING MECHANISM.

Application led October To all whom t may concern:

it Aknown lthat I, PETER J. PAULY, a Mcitizen'of the United yStates, 7residing at St. Louis, State of Missouri, have invented certain new and Vuseful Improvements in l ail- DooreLooking Mechanism, yof which the fol- :lowingis a specification.

My invention has relation to improvelments in jail door locking `mechanism and l0 consists in the novel features of construction `more fully set forth in the specification and fpointed out in the claims.

1-Brie1y.,tlfie invention consists in a `locking mechanism orajail door, said Ymechanism 1`5 being enclosed within a suitable case ad* jacent to which the :door is mounted, said door being adapted to receive a plurality of .looking `bolts which are mounted within the case and project ythrough .the 4wall "thereof for lthe purpose of engaging the jail door.

The-locking bolts are accessible only from i'mside of the-case 'which isprovided with a door carrying a combination lock so that it may not Lbe-opened by anyone other than the turnkey -orfcustodian of `the ail.

It is lthus among-.the objects of the inven- `tion to :provide a jail door locking mechamism which is yas .nearly absolute proof .againstaildelivery as'hurnan ingenuityr can make jit. A .further object is to provide a lockingl mechanism for doors which fis selcured againstdislod'gment by .a device witl1- vin the case housingT 4the mechanism, isaid dev-ice associated with the `door with-in thecase yso that under no circumstances can the locking mechanism be operated unless the case door 7is open. Further sand other advan- .tages will be better apparent from a detailed description 4of the `invention in connection with the accompanying drawings in which- Fig-ure 1 is aplanofa jaifl building show- ;ing ,the `arrangement of the cells and other vlrooms 4together with 'their respective doors; Figure 2 lis a vertical, longitudinal section .taken on the line .2 2 kof F ig. l showing the jail partition and 4cell doors in section; Figure -8 isa section view llooking from the end of the jail corridor into the case housing .the locking mechanism, the door of said case being open.; Fi ure 4 .is a vertical cross section taken on t `e line 4--4 of FigA 3 with the case omitted and parts broken away; Figure 5 .is a horizontal cross section taken A5, 1925. :Serial No. 60,518.

on vthe line 5 5 of Fig. 3; Figure `6 is a vertical cross section taken on the line 6 6 of Fig. 3; Figure 7 is a horizontal cross sectional detail taken on the line 7 7 `of Fi 3' Figure 8 is a cross sectional `detail taken on the line 8 8 of Fig. d', the locking' bar being shown in position when the locking bolts are free to be moved; Figure 9 is a cross sectional detail 'similar kto Fig. 8, the locking bar, however, having lbeen dropped into engagement with the locking `bolts and also 1with the lock zpin of the door operated trigger.

Referring to the drawings, .l represents the case or box for housing ithe locking mechanism which is provided with a door ,2 adapted vto be locked by means of a combination lock 8. The box is mounted in the guards corridor "C in line with partition P in which are the cell doors D, D 'and the door D `leading to the safety `vestibule V. The safety vestibule `is also provided 'with a door dleading to an assembly or dining room A, Vthe door d, it will be observed, being disposed at right angles to the celldoors D, -D and D. Between the guards corridor lC and prisoners corridor C `is a hinged door d', said door being adjacent to the box l and being adapted to close against a bar 4 in closely fitting relation with the side 5 of said box. A :plurality `of locking bolts 6, 6, 6' Vconnected together Kby a lbar 7 are disposed Within the 'box 1, .and their ends adj acent tothe door CZ are arranged to operate through the wall '5 yof Athe box, the opposite ends of ybar 6, 6 being mounted in openings o, `0 of brackets S, 8 secured to the rear Wall 9 of the box. An angle bar 10 is secured lagainst the rear wall 9 lof the box in spaced :relation with the brackets 8, 8 and a locking bar 11 is positioned between the angle bar 10 Land brackets 8, 8, said plate il being provided with openings l2, 12, 1Q. to .receive the ends of Vthe ' locking bolts 6, 6, 6, the latter being provided with notches 13, 18, 13 on their upper surfaces to receive the upper `mart-,wins ofthe openings l2 for lholding the locking bolts in locked position as will be better apparent hereinafter. A spring s is disposed on each bolt 6 between a collar Z3 and the bracket 8, said spring operating Ito `exert pressure Von the bolts 6, 6, G thus keeping them in 'their' enters most positions 3.),

When the bolts G, G, G are in their normal locking position, they project through suitable openings in the wall 5 of the box 1, and are locked in this position by means of the locking bar 11 which drops downwardly so that the openings 12 therein engage the notches 13 in said bolts. However, the bar 11 is only free to descend when the door 2 is closed because of the trigger 14 which is acted upon by a lug 15 secured inside the door, the inner end lei of said trigger operating a lock pin 16 mounted between ears 17, 17 and traversing the bar 11 (Fig. 4). l/Vhen the door 2 is closed the trigger is moved inwardly by lug 15 to a position that will bring said bar in register with a notch 18 on the upper side of the pin 16, thus permitting the bar 11 to descend into said notch. lVhen the door 2 is opened and the lug 15 withdrawn from the trigger 14, said trigger is free to assume the position shown in Fig. 5 under the iniiuence of a coiled spring 19 disposed about pin 16 between one of the ears 17 and the lever arm 14.

A disc 2O is rotatably mounted on the inside of wall 5 and somewhat spaced from said wall, the disc being provided with a handle 21 whereby the same is rotated and a slide bar 22 is slidingly mounted on the inner surface of said wall 5, said slide bar having a stud 23 projecting from it into a slot 2s' in the disc 20. The inner end of slide bar 22 is connected to one arm of a bell-crank lever 24', the opposite arm of said bell-crank lever being connected to a bar 25 which is rigidly secured to the bar T connecting the bolts 6. Therefore, if the disc 20 is rotated in the direction of the arrow (F 6), slide bar 22 will be moved inwardly, thus rocking the bell-crank so as to move the bar 25, and, of course, bar T and bolts 6, 6, G to withdraw said bolts from the openings 26 in the marginal bar 2T of the door d. A connecting link 28 is connected at one end to disc 2O opposite to the point where said disc makes connection with the slide bar 22, said link being connected on the opposite end to one arm of the bellcrank lever 29, the opposite arm of said bellcrank lever having one end of the connecting link 30 secured to it, the link 30 being connected at its opposite end to the depending arm of a bell-crank lever 31, the laterally projecting arm of said bell-crank lever having a stud 32 projecting from it in proximity to a boss 33 on the lock plate 11. The purpose of this last descibed mechanism being to lift the locking plate 11 by rotating the disc 2O in the direction opposite to the arrow (F 6) thereby raising the stud and forcing the lock plate 11 upwardly. 'Of course, when the trigger 1-1- is in the position shown in Fig. 7 with the door 2'closed, it is impossible to move the disc 20 to a position for raising the lock bar 11 because said lock bar is held against movement by the pin 16 as heretofore explained. The locking bolts 6, 6, 6 cannot be forced inwardly by pressure against them by their outer ends when the locking plate is in its normal position in engagement with the notches of said bolts, and when the door 2 is closed, it is obviously impossible to release said locking plate in any way from its'engagement with the locking bolts. Thus when the door of the box 1 is closed, there is no way to open the door d.

Having described my invention I claim:
