Application January 21, 1941, seriai No. 375,303 l Y claims.v

This invention relates to locks particularly adapted for use in connection with trunks or other equipment having hasps, keepers and locking means therefor.

In trunk locks it has heretofore been common to provide a lock which may be opened either by a key or by combination means. In this type of lock the locking means has usually been mounted on the trunk within the keeper plate andthe combination means only has been mounted on the hasp. Such an arrangement does not lend itself well to employmentv ofv a standard key operated lock, and thejuse of a standard key operated lock in conjunction With the combination means is very desirable from the standpoint of availability as Well as'economy. Y

Moreover, mounting of the `key operatedrlock mechanismen the trunk Within the keeper plate and mounting of vthe locking means only ony the hasp involves considerable installation trouble -in attaining the proper co-operative action between the mechanism and the means because of inaccessibility of the key operated lock mechanism. Further, the keeper plate, with the`key operated lock mechanism therein; 'and the hasp which carries the combination means,k are both riveted to the trunk, and in the event of trouble Yin in stallation of the combination means in -co-'ope'rative relation with the key operated vlock -mechal nism, the keeper plate, or the hasp, or both, may have to be removedl from the trunk after Vbeing riveted thereon,`with resulting danger of damage to the trunk. This Yalsoapplies if repairs are necessary. v i Y Accordingly, the principal object of my invention is to provide a lock that may bepoperated either by a key or by combination means and Which, by reasonof mounting of both key oper'- ated lock mechanism and combination operated mechanism on a hasp,` overcomes objections such as pointed out above. n M i Another object of my invention is to provide a trunklock that may i i or by combination means Vand which,l due to mounting on both key operated lockmec'hanism and combination operated meol'ianism` on a standard trunk hasp, enables the use of standardl key operatedv rtrunk lock mechanism Without-requirement for additionalinstallation space crundu'e projection of the lock from the trunk. j

A further objectV of my invention isv to prof vide' a lock thatimaybe opened either' by akey or by combination means and which, by improvement in arrangement, construction andI selective `operation of key and combination controlled be opened either by 'ai'key' or any other type of equipment parts, affords an extremely I, compactfecient,

The trunk 'lid l l 'has' afkee'per plate .I8 having at the bottoni anspressionul'g `for reception of the hasp 15 proper, and saidplateaiscfhas above said depression I9 an'farjcuate recess' 2D ferrer ception of thecupi mici]said-naspz Acrcuia'r opening 2 i is formed in the keeper plate 't8' centrally and `within therecess', and when the'l-id ll of the trunk-is closed and the fhasp isis swung into engagement with thekeepe'r plate I8,- boltshereinafter v described and-which are mount; ed on the hasp 1E', kpass through the' cpeninglii and are engaged back ofthe edge tof `lockthe trunk.` A The keeper plate 'l'is "securedrto-the -l'id- Ii of the trunk, as .b y rivets `lf2, which?" pass through Z3 'formed oh said vplate and openings' in ears 1, looking bearing against the lid at opposite sides of the opening therein. Secured to the keeper plate i3 at the rear by rivets 24, is a plate onthe trunk lid provided with a lock casing receiving cup 26. In accordance with my invention a lock, which may be opened either by a key or by combination means, is mounted on the hasp l5 and passes in and out of the keeper plate opening 2| and the cup 26 when the hasp I5 is swung toward and away from the keeper plate I8. Said lock is preferably mounted, constructed and operated as follows:

An annular lock casing 21 (Figures 2 to 7) is provided to house movable parts of the lock and said casing has in its side wall, diametrically opposed bolt openings 28. The casing 21 is further provided with cover plate lug receiving re cesses 29 aligned with the bolt openings 28, and

with diametrically opposed attaching lugs 30 spaced ninety degrees apart from the recesses 29.

Slidably mounted in the casing 21 to pass in and outof the bolt openings 28 are spaced, opposed lock bolts 3|' formed integrally with a pair of lock bolt plates 32 slidably loverlapping each other in said casing, each having'aligned, spring receiving slots 33. Positionedin kthe slots 33 and bearing against lugs 34 on the plates 32 are small coil springs 35 which act to force the plates 32 and the bolts 3| outwardly in opposite directions so that said bolts normally project outwardly of the casing 21 through the bolt openings 23.Y The springs 35 and beveled faces 35 on the bolts 3| enable said bolts to snap past the circular edge of thekeeper plate opening 2| when the liasp l5 vis swung toward the same. Thereupon the bolts 3| through the action of the springs 35 engage lthe backof keeper plate I8 adjacent the opening 2 to lock the trunk.

The lock bolt plates 32 are provided centrally thereof with key lugs 31 and key spaces 38 (Figure '1) which, when the plates are assembled together, present a key opening 39 (Figure 4) disposed centrally of the lock. In accordance With my invention, the bolt plates 32 are provided with pins 4l] forming part of a connection whereby the lock may be operated through the medium of means hereinafter described.

Arranged for partial rotation in the casing 2l', and bearing against the lock bolt plates 32, is a substantially circular connector plate 4| (Fig- -ures 5 and '1) providedv with a key opening 42 axially aligned with the key opening 33 of bolt plates 32. The connector plate 4| has diametrically opposed, substantially triangular shaped Acam openings 43 in which extend the pins 40 oi bolt plates 32. Pivotally mounted, as at 44, upon the connector plate 4| isa lever 45 which has at its free end a disk engaging lug 43. Secured to the opposite end of the lever 45 is a leaf spring 41 that extends between the side wall of the casing 21 and a lug 43 on the connector plate 4|. A key plug 49 (Figures 2 and 9) is provided axially with opposed inreaching slotted openings 50 which, when said plug is fitted in casing 21, are aligned with the key openings 39 and 42 of bolt plates 32 and connector plate 4|, respectively. When opening the lock by a key inserted through the openings 50, 42 and 39 whereupon, by vturning the key in the proper direction to engage the key lugs 31, the bolts 3| and plates 32 will be drawn inwardly toward each other so that Vrthe lock may be opened.

The key plug 49 is provided with an enlarged head 5| and a reduced shank 52.` The shank 52 has rotatably fitted thereon a ring53 having peripheral key Ways 54 and 55. Mounted on the ring 53 is a lock casing cover` plate 55 provided centrally with an opening 51 and lugs 51', 51" which fit in the key ways 54 and 55 of said ring. The cover plate 53 is provided with diametrically opposed lugs 58 for securing the plate 56 on the casing 21 in the recesses 29 thereof. The cover plate bears against the head 5i of the key plug 49 and said key plug and the ring carry lock opening means preferably arranged and con structed as follows.

A washer 59 (Figures 2 and 8) is tted on the ring 53 back of the cover plate 56 and has a lug 59' engaged in the key way 54 of the ring. Bearing against said washer and rotatably mounted on the ring 53 is a .disk 50 provided centrally with an opening 6| through which the ring 53 extends.

eral notch 63. A washer 64 is mounted on the ring 53 and has a lug 64 tted in the key way 54 of said ring. The washer 64 bears against the disk 60 at theside opposite that bearing against the washer 59. l

Rotatably mounted on the ring 53 Aand bearing against the washer 64 is a disk 65 provided centrally with an opening 66 through which the ring 53 extends. Secured to the disk 65 is a lug G1 which extends into the slot 62 of the disk 60 for interengagement therewith. The disk also has a lugr 68 extending in a direction opposite that of the lug 61 and having a function to be presently described. The disk 55 has a peripheral notch 69, and mounted, on the ring 53 and bearing Aagainst. said disk is a Washer 'l5 having a lugr 19 iitted in the key way 54 of said ring.

Rotatably mounted on the ring 53 andA bearing against the washer 10 is a disk 1| provided centrally with an opening 12 through which the ring .53, extends. The disk '1| Vcontains diametrically opposed arcuate slots 13 and 14 andl a peripheral notch 15. The lug es of disk ssfextenss through slot 13 of disk 1| for interengagement therewith,

`and mounted on the ring 53 at the side or" the disk 1| opposite thatr bearing against the washer ,10 is a washer 16 having a lug 16 tted in the key way 54 of said ring.

The keyplug 49 has xed thereonand beari The key plug 49 and described partscarried thereby constitute a unit which is associated with the described parts in the casing 21 and secured therewith on the hasp I5 in the cup |6. Accordingly, the several Adisks 60 65,v 1|, andthe key plug 49 and control plate 11 are rotated relatively to align notches63, 69, 15, thel cam 8| and the shoulder 82v with each other.Y Thereupon, the key plug and combination unit is placed in the kcasing 21, so that I the detent 83 of the pivoted lever-45 enters the space between the cam 8| and the shoulder 82 of the control plate 11, and the disk engaging lug Y46 of the lever 45 enters the notches 63,l 69,15 of the disks. Under these conditions, the-lugs58 of cover plate 56 will be aligned with the recesses29 in the casing 21 so thatupon pressing-the lugs' in said recesses, the

cover 'plate 56 A'with the keeper plate -'the lock passes out of the cuplcounter-clockwise `as viewed in Figure "the 4iirst-of the three that theirA notches 15, '69, 63, are broughtinto 'is secured' .on the casing 21 .over the parts therein and with the key plug projecting outwardly of the cover plate throughV the opening 51.

The casing 21 and parts'therein are now placed in the cup I6 of the haspy i5 so that thefront vend of the key plug lI9 projects forwardly ofthe hasp through an opening 84.-(Figure 2) formed in the hasp cup I6 centrally thereof. At the 30 ofthe casing 21 are ySe- (Figure 3) formed in the same time, the lugs cured in openings 85 -hasp cup `at'opposite sides. of the opening 84, and

Vthe vlock is thus securely fastened to the hasp, The key plug 49 has in its sides 'of' the key'openings 50, threaded openings 88 for the'reception of small screws 81 whichserve to secure Va circular dial 88 to said key plug andpass through vopenings formedin said dial. The dial 88 s.-thus hasp i5 overa rounded portion of the cup i6 so as tobe rotated to set `or unset the disks En, 65, 1 l, as hereinafter described.

The dial 89 contains key slots 89 aligned with thev key slots 50 of the plug 49 and with the key Aopenings 39 and 42 of the bolt plates 32 andthe `connector plate-4|, respectively. The dial 88 has an annular beveled portion 90 providedr therearound with a scale including the usual graduated marks and 'numbers herein shown as comprising the 'series 0 to 9, inclusive. Throughrotation of the dial 88 predetermined numbers 'of this series .are successively brought opposite a mark 9| on the keeper plate `I8 to set the disks 69, G5 and 1| so that the Vlock may be opened by the dial.

In the operatio-n of key, the hasp will be closed as `shown in Figures l to 33, inclusive and the bolts 3|v will be engaged t8- at the' rear. The key is inserted through the openings 39,59, 42 and 39 of the dial '88, key plug 49', connector plate 4|, and bolt plates 32, respectively, whereupon-by turning the key in the proper direction it engages the lug-S -"31 Yof the bolt plates 32, thus drawing said plates and the bolts v3| inwardly againstthe plate and bolt expanding `action of vthe springs 35, and disengaging the bolts from vthe Akeeper plate' |18. The lock nowbeingf opened, the hasp *Ifemay then be swungforwardly at which time 25 'through fthe opening 2| fof the keeper plate |58, andthe lid I` of the trunk iHi-y canthereafter be raised to open the trunk. Y

' suming now that the lid of the tru-nk has been closed, that the haspis also closed as shown inFigures -1 to 3,- and vthat it isdesired to open the loc-k by Vthedial I88. instead ofthe key. The disks 60, 65, 1l, being at this time un-set, itis necessary to-'set' them, which is accomplished byv rotating the dial '-'8'8 lto successively bringthree of a predetermined combination 'of the numbers thereon on- -the keeper plate I8. is. turned to the leftor 1, to bring numbers of 'the combinaition opposite the mark 9L, whereupon fthe .dial is turned to the rightor clockwise to bring the Isecond'of the' three numbers opposite the `mark A`9|, after which said .dial is againk turned tothe -leit or eountereclockwise to fbring'the third `of said numbers opposite Jsaidmark.

This, throughfrotation lof-the key plug' v'1|'9 and the control plate 11 by thedi'al v88, and 'interen- 'gagem'ent oli'fsaid plate and tl'ife disks 1|., 65,150, through'themedium of theilugs: 81D', "68, 611, the

` Thereupon, through vfurther rotation of the dial clockwise or to the right,` the keyplug 49, con- -trol plate 11 and disks 1|, 65, 69, are likewise rotated, causing, thel shoulder 82 and the detent 83 engaged therewith to rotate the connector plate 1| so'that the cam edges gage the pins 48 of the4 bolt plates. 32 and slide said bolt plates and. thebolts 3| inwardly toward each other againstthe.. bolt and plate expanding action of the springsr 35. The bolts 3| are thus disengaged from the keeperr plate i8, the lock vis opened, and the hasp i5 may then be swung outwardly', yat which time the lock passes outgof the cupv 25 through. the keeper plate opening A2|.

When'the hasp-,l5 has, been swung outwardly' vthe dial 88 .is turnedto. the ,left or counter-clockwisel This causescorresponding movement of the key'plug 49v and the control vplate 11 so that the carngSi `on the control plate forces the detent 83 with pivotal movement oi the lever,l 45 outwardly and the detent 83is disengaged from the shoulder 82 of the control plate. At the same time, and through thisy action of the' camfL-the lug d ofpthe lever 49 is disengaged .from the 1I, 65, G8.,frespec beyond the latter. Byv further 'turning of the dial 88 counter-clockwiseorto the lef-t, the keyplug 49 and the control platev 11 receivecorresponding movementwso that through interengagement of the lugs. 89, 6:1,

The lug 4'6 of the 4liever 45- isy thus, through nn- 'setting rotation of the disks, `engaged with un notched edge portionsv thereof and the connection between the controlplate 11 and the connector plate 4l. is broken. When said connection is broken, the springs 35 force the boltv plates 3:2 and the bolts 3| outwardly, with accompanying partial rotation of the connector plate 4| due to riding fof the pins. 49 along the cam edges of the openings- 43 to. the outer ends thereof. With the hasp l5 swung forwardly, .the lid ill of the trunk may be opened, and when said lid is closed and the hasp I5 is swung rearwardly into engagement with the keeper plate i8, the bolts 3| are engaged. back of. lsaid-plate and the lock enters and is positionedin the cup- 23y of the plate 25. Thereupon the lock may be opened either by the key or by the dial., as previously described. p

A key operated lock standard construction may, in accordance with my invention, be ernployed in conjunction with. combination means on a hasp, through the novel arrangement and yconstruction of the parts and connections com'- prising said invention, and while the Yuse of Aa standard key operated lock is contemplated and, with thev exception of the pins 4|),v is in all sub.- stantia'l respects disclosed 4in conjunction with the form of embodiment of my invention herein .illustrated `and described, itis to. be. expressly ofy its openings 43 er1- ing plug therefor both mounted understoodthat my invention is not limited yto such a lock or said form of embodiment or otherwise than by the terms of the appended claims.
