Application filed July is,

My invention relates in general to locks, and in particular to a permutation. or combination lock.

Some of the objects of my invention have been to provide a lock of this nature which shall be durable in construction, and inexensive to manufacture. i v

Another object has been to provide. a lock which, may have its combination easily changed without disassembling.

Moreover, my device is provided with means whereby it shall be impossible for an unauthorized person to detect the combination by feeling. h

Furthermore, my device is of such a nature that it is susceptible of a number of various uses.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which Fig. 1 is an enlarged, longitudinal, sectional elevation of my complete device.

Fig. 2 is a transverse, sectional elevation thereof taken on line 22 of Fig.v 1 and looking in the direction indicated by the arrows.

Fig. 8 is a side elevation of the device showing itadapted for use as a padlock.

Referring to the drawings, 10 represents the casing of my device which is cup-shaped. Mounted within the interior of the casing 10 isa plurality of tumblers, each, comprising a lock disc 11 anda tumbler disc 12, corresponding in number to the number of'combinations desired. In the drawings, but three of such lock discs are: shown,.it' being obvious that a greater or lesser numberinay be provided if desired. g

The tumbler. disolfZv which is. provided for each; of. the lock discs 11 is... mounted within a recess- 13 provided in. eachiof. the lock discs. Each; of the tumblerfdiscsz. is carried by. the flanges 14: and 15', provided 1925.. sem in. 44,620.

on a] tumbler hub. 16, The. pressure of. the

flanges

14 and 15 .againstthe tumbler disc 12 is such that will firmly; hold the disc in position, but whenlconsiderableforce is applied, thedisc may be made. to move and lo tate about-thehub, whereby the combination 1 may be easilyand quickly changed. The

hub 16 is providedfwith annular-extensions 17 and 1:8,,whi ch engage. with bearings-pertures'; 191 formed in thelock discs. By reference to Figuresl and 6,.it will be seen that the annular. extension 17' of one hub 1.6 and the annular extension 1 8:0f the adjacent hub are .111 contact with each other and; that the aperture 19v offthe lock disc 11- 'forms a bearing for the two annular extensions of. adj acenthubs. Each hub 16 is provided with a central bore 21andwithanannular recess or counterbore: 22. A. longitudinal groove or keyway 23 is provided in the. portion of the hub which is providedwith the bore/21 for purposes. to. be hereinafterdescribed. Theflange 15 ofthejhub is: providedon its per phery with a number of indentations 20. These indentations are engageable with a spring 245 which is preferably held by the lock disc -ll. The spring is so designed. that it will engage with the notches of the flange and serve to temporarily hold it i'n any set position. Each of. thetumbler discsy12 is provided with a notch in its periphery for purposesto be hereinafter described.

Av cover25 is provided for thebody 10 and is preferably set into a recess 26 and against. a shoulder 27 formedtherein. The

cover 'may be. secured in position by any suitable, meansgbut since the lock discs 11 must be prevented from rotation, it is con.- venient to secure the cover in position; by means of ainmn'ber of rivet's28' which are passed through the cover, the lock discs and the bottom of the casing 10,. The cover is providedwith a hub 29"havinga bearing for tlie operating. which is slidable andf-rotatalile. within. thej'hub; I The stud is provided with: an operating. knob 31 having an indexffin'ger 32'. Thehub isprovided with av number ofilongitudinal] scores "or marks 33,, corresponding in.1 1um lier to; and registering. with, the, number. notches 20 provided. in, the; flange of the." hub 116. Numerals. 3.4: are preferablyjprovided for the scores 33andlthesejare stamped upon the; face. of the cover i 25. Y The. inner end of the operating. stud; 301 's" engageable withthe bore-.2 21;. of. each. tumbler hub 16', and a.

is carried by the end of the operating stud and radially arranged so as to engage the grooves 23 formed in the tumbler hubs. Since the recess 22 in each of the tumbler hubs is larger than the diameter described by the pin 36, the pin will be free to move around in the recess without causing the rotation of the tumbler hub. WVhen, however, the pin is moved in the groove 23, the tumbler hub 16 may then be rotated by the rotation of the operating stud 30. The operating stud 30 is provided with a number of annular semi-circular grooves 37, equal in number to the number of tumbler discs. A spring 38 is carried by the hub 29 of the cover, and its end 39 passes through a slot formed in the hub, whereby it is engageable with any one of the grooves 37 when such groove is moved into registerable position therewith. The grooves are so arranged that the spring 38 "will engage with one of them when the pin 36 is in engagement with the groove 230i either of the hubs. This forms a flexible stop for the longitudinal movement of the operating stud 30 when the lock is being manipulated.

A look bar 41, preferably of rectangular cross-section, is passed through suitable slots formed in the cover 25, the edges of the lock discs 11, and through the bottom of the easing 10. This lock bar is provided with a number of notches 4-2 in its edge which is adjacent the tumbler discs, and with which the tumbler discs are engageable. As shown in Fig. 1, the tumbler discs lie in these slots and'thus lock the device. When, however, the notches of each of the discs are brought in registering position with the lock bar, the bar may be freely slid out of the lock.

Arranged in a recess of the cover 25 is a floating disc 6L6.- This disc is mounted upon the operating stud 30 and is provided with a key 47 extending inwardly from its central aperture and engaging a keyway 48, provided in the operating stud, whereby this discwill be rotated when the stud is rotated. A notch'35 is provided in the periphery of this disc like the notches 35 of 3 the other discs. M

hen my device is locked and it is desired to unlock the same, the combination being known, the operating stud 30 is moved axially so as to preferably engage the hubs in succession. The first position will be that shown in Fig. 1 where the pin 36 of the operating stud is in engagement with the groove 23 of the first tumbler hub. This hub is then rotated until the index finger is brought opposite the numeral of the combination corresponding with the first tumbler, after which the operating stud is pushed inwardly until the pin 36is out of engagement with thejgroovef 23 of the first hub. The stud, While being rotated, is now urged inwardly against the next succeeding tumbler hub, whereupon the pin 36 will be brought into engagement with the groove 23 of the next succeeding tumbler hub. The axial movement of the stud is then continued until the end 39 of the spring 38 engages with the middle groove 37 on the stud, which will act as a temporary stop. When the operatingstud is in this position, it is connected with the second tumbler hub 16 and the same may now be rotated until the index pin is opposite the number corresponding to this tumbler. The operating stud is then moved axially, as just above described, until the pin 36 engages with the groove 23 of the last tumbler hub and until the spring 38 engages with the last groove 37 on the stud, whereupon the last tumbler may be rotated to a predetermined number. The operating stud is now moved axially to a position where the pin 36 will lie in the recess 22 of either of the tumbler hubs, and the floating disc 16 is then rotated to bring its slot 35 into registering position with the lock bar 11, whereupon the same will be released and may be withdrawn. The slot 4L9, formed in the lock bar for the floating disc 46, is narrower than the slots 42 for the tumbler discs, and the reason for providing the floating disc is that the notches 35 of the tumbler discs 12 may not be felt by an unauthorized person as they are being moved past the lock bar.

'My device is of such a nature that it is applicable to various uses. In Fig' 1, I have shown it equipped for use as a keyhole guard or lock. WVhen so used, a lock pin 51 is carried near the top of the casing, and this look pin provided with a detent pin 52 extending at right angles with the axis of the lock pin and arranged at an angle with the diametrical center line of the device. This lock pin is arrangedimmediately above the lock bar 41, and when the device is used as a keyhole guard, the lock pin is first in serted in the round part of the key hole, whereupon the entire device is slightly rotated .so as to bring the lock bar in registering position with the slotted part of the key hole. The lock bar is then inserted in the slotted part of the keyhole and the device locked by rotating the tumbler discs 12 to various positions. By reference to Fig. 7, where the keyhole is shown in dotted lines, it will be seen that the detent pin 51 will prevent the device from being withdrawn from the. keyhole. W V

Another use of deviceis that of a pad look, as shown in Fig. 8. When so used, a hasp 53 is provided, which is formed with a flattened end 54-, which takes the place of the lock bar 4-1, and with an end 55 which passes through an opening 56 formed in the body 10 and arranged preferably at a point diametrically opposite the lock bar;

It is obvious that when the lock bar 41 or the hasp 53 is inserted in the device, the tumblers are set by being rotated, as herein before described, to various positions.

Obviously, some modifications of the details herein shown and described may be made without departing from the spirit of my invention or the scope of the appended claims, and I do not, therefore, wish to be limited to the exact embodiment of the form herein shown and described, the form herein shown being merely a preferred form.
