245, andoonsists in a construction vof such locks Vwhich adapts them for operation by a series of keys, all of which must be usedin the proper order to operate the lock. l. The main object ofmy invention is to provide a pin tumbler lock, each tumbler of which may consist of a plurality of segments adapted to be consecutively raised to different heights by different keys to part at different points, and thereby permit successive rotation of respective portions of the lock which are normally held in locked position by .engagement therewith by the pin tumblers e An additional object of my invention is to provide a vchangeable key construction for such a lock wherein any one of the multiple keys used in the locks operati-on may be changed by the possessor thereof, so that the original key cannot be successfully usedI and sothat other keys of the series required for ther locks o-perationvwill not beafl'ected.I A further object-of .my invention is to provide an adjustable feature whereby the lock may be set torbe operated completely by any desired one of the series-fof keys iitted thereto. n
In the accompanying drawings, which illustra-te my linventiomfw Figure 1 is ajvertica'l longitudinal -section through my improved lock with one of 'the multiple keys inserted. e Figures 2.13.0 6 lnclusiveare vertical. lem-se sections taken on the il e ot Fig Application filed rDecent-loer 8, 1921; Serialglib. 520,949'.-
ure' 1,bu't showing' the elements of the lock indifferent operating positions, asher'ei'nf after described.'
'Figures 7 a'nd 8 are details of two ofy the lock members.
y,The lock' case 1 is cylindrical upper and lower' rectangular projections 2' a'ndv 3,1 respectively. Rotatabl'ev within case 1 is an annular ring L Rota'tabl'e Within ring .4'is an annular ringy 5. and' rotatable withinjects into arecess lllinrinjg 4, thus tem'- porarily lockingri-ng's- 4 and' against relative rotation. TheV head of pin 13 projects into .a recess v1 5 in ring -1, thus temporarily withdrawing the point-'of the pin within the inner periphery'of the ringV so that it does notinterfere with rotation of plug 6.3
Ringe is similarlyprovi'ded with pins 16 and 17 and case 1 with a recess 18 for the point yof vpin 16 and aurecess 19 for the head' of. pin 17.l .Each ofthe above-mentioned pins, is preferably provided with a- ,coil spring tending. to thrust the pin in the direcv tion Awhich its head faces. (SeeFigs. '7 and' 8). VThuspins 12v andv 16 tend to move in- `wardly ,and pins -13 and 17 tend to Vmove outwardly..
Each .of therecesseslfor the heads' of pins 12, 13, 16 and 17` has one edge inclined as' shown which serves. to cam the pin out `of :the rei-fessure; .auch .relative rotation-cf the ringi is a. cylindricalplug'6. The rear endv two members, with which the head engages, as will torce the inclined edge against the pin head. Plug 6 and ring 5 are provided with recesses 2O and 21, respectively, adapted to receive the points of pins 13 and 17, rerespectivcly, when aligned therewith.
Plug 6, ring 4 and ring 5 are provided with studs 30, 31 and 32, respectively, and ring 4, ring 5 and case 1 are provided with respective slots 33, 34 and 35 extending substantially halt-way around the respective inner peripheries ot' the rings and case and serving with studs 30, 31 and 32 to permanently limit theA relative rotation of the adjacent members which carry them.
Projections 2 and 3 in case 1 are each provided with a series ot recessesfor driver pins 22. I have shown tive ot such recesses in each projection, but this number is immaterial and as the drivers in each recess A when the same is inserted in the lock and to be thrust iu'ardly by springs 23 and which press on the case drivers. The key A is held against movement transversely of the plug by the usual rib A and a corresponding recess in the plug.
Assume key A to be the tirst ot' the series of multiple keys which operate the lock and inserted in plug 6. The two (or more) pin tumbler segmentf` and 26 in plug 6 are raised so that their outer ends are flush with the outer periphery of plug 6. Rotation ot' key A to the right as Lfar as possible will move the plug to the position shown in Figure 3 which will align recess 2() with the point ot pin 13 and will align a recess 27 with the head of pin 12. The spring on pin 12 will in'nnediately thrust the pin inwardly so that its head enters recess 27 in plug 6 and disengages ring 4, thus ceasing to function to prevent relative rotation of the two rings. a
Key A is now withdrawn and the next key B of the series may be inserted, as shown in Figure 4, whereby the outer end of tumber segments and 28 are raised to the outer periphery ot ring' 5. Righthand rotation of key B will now cam pin 13 inwardly out ot the recess in ring 4 and into recess 20 in plug 6 and rotate the plug and ring 4 as a unit to the position shown in Figure 5.
The third key C is now inserted (Figure and raises the pin tumblers so that the outer end of tumbler segments 28 and 29 are raised flush with the outer periphery of ring 4 which leaves ring 4 free to 10- tate in case 1. Such rotation cams pin 17 into ring 4 thus locking the two rings together. As plug 6 and ring 5 have been previously united by inward movement oi' pin 13 it is obvious that the plug and both rings will rotate as a unit within the case to throw the lock bolt to unlocked position.
l/Vhen the lock is to be locked it will be necessary to use each key in the reverse order in which they were used in the unlocking operation.
It is to be understood that the pin tuinblers serve to hold the lock members against any movement except when certain keys are inserted and the function of the uniting pins is to prevent simultaneous movement of the plug and rings prior to the Vsuccessive rotation of the members as described.
Wrhile I have shown two rings between the plug' and the case, one could be used without changing the construction of the lock and only two keys would be required to operate the lock. @t course, the rings may be increased in number to any desired extent,
in Figures S) and .10, I have illustrated a construction which requires two keys to be used in succession to operate the lock and either ot these keys may be changed by the possessor thereof for another key having a different bit arrangement. in these figures, the case 40 and plug 41 are like case 1 and plug 6 above described, except that case 4l) is provided with a longitudinal recess which receives a sliding bar 42, similar to that shown in my copending application. Serial Number 514,245, which normally provides a continuous portion ot the interior perishery ot the case upon which slides the head. of uniting pin 43 in ring 44. Bar 42 may be retracted manually however, so as to align a recess therein with the path ot movement of pin 43, which recess will receive the head. of the pin and permit retract-ion o't' the point of the pin from ring 45 when key X is turned to the left.
Plug` 41, ring' 49 and ring 45- are then turned to the right and when stud 46 reaches the righthand end of slot 47, it will positively engage ring 44 when the inclined edge of the bar recess in case 40 will cam pin 43 back into the normal position shown in Figure 9.
'lVhen the lock is tobe operated in the' ordinary manner, the kabove described keychanging-elemmts do not function.v Then, a stud l on ring 44 yand a slot 55 in case 40 function as do stud 32 and slot 35 in the preferred form previously described'. Similarly ring 49 and ring 45 are provided, respectively, With a stud 56 -and a slot 57. lVhen the iii-'st operating key has rotated plug 4l and ring 49 to-` the right as yfar as stud 30 and slot 34 permit, it is Withdrawn and a second operating keyinsertcd, which raises the` pin `tumblers so that they may part at the outer periphery of ring 44 and permit -further rotation of both rings and the plug to the ilim-it provided by stud 5l in slot 50;, Wliiich will unlock the lock. These partial rotations by different keys must be r `fersed'l to return thel lock to locked position.
In thisy kmodiication,y the lower pin-Way in the plugs and ringsisnot continued. into ring 44 and' the lower pin-tu'mbl-ers cannot be positioned in the upper pin-Way so as to rendervinoperative the key changing velements. f
'In this construction, the totali rotation `of the plugi-s li-mitedto less than a full revolution by studs 51 and 52 and their slots but such limited rotation is ample to provide for the use of two multiple keys and their tumbler segment changing elements.
