This invention relates to improvements in permutation locks, and especially to that class of locks adapted to be used in connection with document boxes, miniature safes, cash drawers and the like. Y I The main object of the invention is to provide a lock of this character positive in action an'dsiniple and inexpensive in construction. r F Another object of this invention is to provide a lock of this-character in which a large number of permutations or changes of combinations may be had with the same device by merely changing the relative position of some of the parts of the'lock.
Other objects and novel features'o'f construction will become apparenta-s the specification proceeds.
In the drawings specification, V y
Fig. 1 is a front view in elevation of a miniature bank with my improved lock apforming a part of this" plied thereto.
Fig. 2 is a sectional View taken on line 22Fig.4.
Fig. 3. is a similar View to Fig. 2 the lock in open position. i r
Fig; 4 is a sectional view on lineal-rd Figs. Band 6 are detail views of one of the tumbler disks; Figs. 7 and 8 are detailview'sof the'other' diskand i Fig: 9 is afragmental sectional viewshowing'how the disks are connected to each other. i y r Referring to the drawings in detail in which like reference-characters denoteethe same" parts throughout the different views, .10 denotes the body portion of a bank'or receptacle provided with a door or plate 11 hingedly connected tothe body portion at .12. The body 10 is provided with a projejc ti'on. 13 at the opposite side of the hinge '12 and the projection 13 has a recess oropen ing 1% therein to accommodate o e end of a bolt 15 slidably mounted in the doc-r11 by means of a 'studf16 secured in the bolt 15 and .pas'singthrough' a slot 17 in the doorjll.
Centrally located on the door 11 therejis' a hole or opening 18. A disk or tumbler 1.9 is mounted for rotation onthe door'11 by mean oif a shoulder 29 on the said disk exbut with tending into the opening 18. A second tumbler or disk '21 is rotatively mounted one shoulder 22 of the disk 19. Riveting eyelets 23 passing through the disk 19 slightly 7 Erica overlie one surface of the disk 21 and tend V to maintain the disks 19 and21 in frictional engagement with each other. The disk 19 carrying the disk 21 thereon is removably mounted on a stud 25 having a regular po lygonal cross section. The disk 19 is pro vided with a'hole 25 having the same contour as the cross section of the stud 25. A dial plate 26 having alphabetical markings 27 thereon is secured on'a' shoulder 28 of said stud 25 between the door 11 and a knob 29 securely mounted onya reduced portion 30 of the stud 25.- A spring strip '31 reinovably fitting inairannular groove 32 in the stud 25 maintains the disks 19 and 21 on the stud 25 inresilient engagement with the door 11. A pin 34 projecting in wardly from the door 11 coacts with a pin 35 projecting from the disk 21 to bring the disks 1-9 and 21into properalinement when operated open the lock. 1
To operate the lock to an open position,.
the knob 29 carrying the dial'plate 26, stud '25 and the disks19 and 21 is turned twice in a clockwise direction until a predeterf 7' mined letter onthe dial'plate comes" inline' with an arrow 36 onthe door 11, and then the knob is turned in the'op'posite direction to-a predetermined point,when notches 37 and 38 in the disks 19 and 21 respectively Will be directly i-n'line with the bolt15. The,
door 'is then pulledoutwardly by the knob- 29 and a cam surface on the bolt 15 pressing against the front edge of the recess 14 will "cause the-said bolt to ride into the notches 37 and 38 and Itjwill be understood that as the rest-e turnedin a clockwise directionto destroy the setting indicated inyFig-xe which is the open position, both jot the disks 1 in unison until the letter B is in line with the door will then when;
nie rrqw, are the 1a t e disk-2min I come in contact with the pin 34 in the door,
which contact will arrest the further move ment of thedisk 21 and further revolution of the knob will revolve the disk 19 only,
' until the letter B on the dial has come in alinement'witlr the arrow a second time at which time thenotclies are again overlying each other and as the knob is turned in the opposite direction the disks will again move in unisonuntil the said notches are in line with the bolt 15, when the door may be opened by pulling on the saidknob.
, It will also be seen from Fig. 3 that when the bolt is in the notches the knob'can "only be rotated inthe direction indicated by the arrowsin Figs. 1 and 3, as the notches 37 and 38 are provided with looking surfaces39 and 40. I
By removing the spring 31, the disks may be lifted from the stud and replaced in a difierent relative position thereon, thus changing the combination which will open the said lock, By using a stud of hexagonal cross section, six difierent combinations may be obtained at will. In the manufacturing of this device however, numerous other combinations may be had by altering the posi- Y tions of the pin ea in the door, or the pin 35 in the disk 21. I r V v From the foregoing, it will be seen, that I have provided a lock simple in construetion, positive in action and one in which numerous changes of combinations may be had both in the manufacturing of the lock andby the owner of such a look after it is manufactured. V 1
In the drawings, I have illustrated a preferred form of my invention, but I do not restrict myself to this form, as many modifi-- cations and changes, may be made without departing from the scope of the appended claims. a a
Having described my invention, what I claim as new is: I I
1. A permutation lock, co iipri-sing a plate having an openingtherein, a notched-disk having a polygonal opening therein, a shoulder on said disk, a second notched disk revolvably mounted on said shoulder, connecting means on one of the disks for frictionally maintaining the other diskthereon,
a polygonal stud passing through the open-' ings in the plate and the first mentioned disk, a resilient member associated with the stud and disks, and a. bolt in operative engagement with the disks and slidingly mounted on the. plate. 7 I I 2. In a. permutation lock, a polygonal stud, ,a'notched disk removably mounted on said stud, a second disk rotatably mounted on the first mentioned disk, means on one of the disks for frictionally maintainingthe ,said disks in sliding engagement with each other, a resilient member in engagement with.
the first mentioned disk removably mounted on the said stud, a slidable bolt on the plate in operative engagement with the disks and means on the said disksto insure 'tllQlI' rotation in a predetermined direction to ac mate the bolt into locking position. I
3. In a receptacle, a permutation lock, comprising a plate l'nngedly mounted on .said receptacle, a notched'disk revolvaloly mounted in'said plate, a polygonal stud'pa ssing through the said disk, at second disk rotatably mounted on the first mentioned dislgmeans associated with' the said disks 1 to frictionally maintain them 'in operative engagement with each other, a bolt 1n operative engagement with the said disks and slidingly mounted on the plate and partly projecting into a recess of the receptacle, a
pin on the second, mentioned disk, a projectingpin onthe plate in the path of the pin through the said disk, a second; diskro- I .tatably mounted on, the first mentioned disk, means associated with the said disks to frictionally maintain them inoperative engage ment with each other, a bolt in operative engagement with the said disks slidingly mounted on the plate and partly projecting into a recess of the receptacle, a pin on the second mentioned disk, a projecting'pin on the-plate in the path of'the pin in the disk, a knob on the stud whereby the disksmay be rotated andbrought into proper, alinement by the said pins to aip'osition where the bolt may be withdrawn from therecess and the plate swung open,riand a resilient 1 member removably mounted on'the stud and in engagement with the first mentioned disk to maintain same in yielding engagement with the plate. a
5. A permutation lock, comprising a plate having an opening therein, a notched disk.
having a polygonal opening therein, a shoulder on said disk, a secondnotcheddisk revolvably mounted on sa d firstinentioned disk, a polygonal stud passing tl'irough the openingsin the plate, and the first mentioned disk, a resilient member associated with the stud and disks, a bolt slidingly mounted on the plateoperatedby the said disks and a locking surface on each of the notches of the disksto prevent the said disks from being rotated in the wrong di rection'. r
