KEYLESS LOCK.

- Application fiiea March 29, 1926, semi No. 98,089. i

This invention relate's tor locks, and more particularly to keyless looks of 'the type known as permutation looks, in whichV a predetermined sequence of operations is required to be performed'in order to open the lock, and contemplates more particularly a lockof the class described having pins rprojecting outwardly from the face plate, which pins inay be located by sense of tou'ch. After thepins havebeenlooated the lock may be operated by senseof touch, aided if desired by the ear.

A lock constru'cted in accordance with my invention includes inany desirableI fea-.

tures, among which may beV mentioned the following V 7 f' Itmay beopened in the dark;r itis practicallyimpossible forr an unauthori'zed person to open it by ringing the combination because of the large number of possible permutations which may exist and the time necessary to set upreach perm'utation';` it cannot be opened Vby,an''unauthorized1 person by feeling for the openings in thelocking disc by exerting pressure on rthe unlocking knob and operating the looking discs, nor by listening for the clicks of the mechanism; and in; case the' combination to which the lock is set becomes known,it may be changed to open only to-a dilferent-com-'I bination. v V The features of novelty. which I believe to be characteristic of my invention are set forth With particularity 'in the appendedV f claims. My'invention itself however, both as to-r its fundamental principles and as to stood by reference to the V'specification and ilcco'mpanying'" drawing, in n which 'Figure 1 is a sideV :elevation of a lock according to-'my invention, vshowing theside I away from the bolt. i y Figure 2 is a front 'elevation thereof.

I A suitable end plate- .S-may v`also be provided secured in any suitable manner to prevent access to'the mechanism of the-lock; Latch (S-which may beof'th'econventional type if desired; is formed onfshank or bar V7, ther latch '6'andl shank 'Z together forming the'bolt, and shank I f -7'is' slidably supportedbyarms 8' (Figz project-ing from rear plate 2. f In order to permit of latch 6- being withdrawn -from the rear-side of the lock, an upwardly and flaterally of screw l0f (Fig. 8). Tl1emember39-pro- ]ects laterally and'upwardly from the shank secnred to thejrear plate2;` Cam' llifis secured in position by-any suitable means projecting piece 9 is secured upon thev 'shank 7 of thefboltyfor'example by means:

such as set screw 14, engagingshaft12,'v and f shaft 12 in turn'risprovided -with ia suitable handle rfor operating it; The handle 15' may'V conveniently 'be formed,integral.;with` V the shaft by bending the shaftand nattening'it. Y

j Referring now particularly to` Figures i andV 8 it Will be seen that'the'bolt maybe withdrawn by operation -of handle 15,'which e inturn `operatesV cam; 117 the j-face of' which engages With projectingV memberV 9' to withdraw the bolt:

Ther bolt is returned to projected position When the'handle '15 vis released through the action of suitable restoring means'such as spring 167 securejd-for example to member 9 and tol support/'8.

iooV

The contraction of this spring restores vthe bolt to lproiected position and likewise-firestores handlel to its corresponding'position after release; 5 i 1 It isf'toV be noted'atV thisfpoint thattheV action 'just described 'iso quite independent i of whether the 'lock is oris not released. In

gardless offwhether thelookisV set.vv

^ other words it is-always rpossiblefto release the bolt from the rear side'of the lock refiio 1 ForZ 'the'p'urpose :of w'ithdrawingfthej mounted upon and operated by sh aft 22 supported for example, by rear bearing 23 and passing through the face plate 1 and terminating in operating knob 24. Cami21 is fixed i-n proper position by suitable means, such 'as setV screw 28.

It will nowibe seen that if the looking discs do not interferc with the movement of the looking bar, rotation of the knob 24 in a counter cloekwise direction will cause cam 21 acting upon vprojection 20 to Vforce the looking bar to theflleft as shown in Figure 7, carrying with it projeotion 18 which en- ,g'ages projecting projection 1.7, in the shank 7 of the bolt, and th'creby wiihdraws the bolt from engagement with the casing.

For a purpose which will la er be described a collar 25 is shown mounted upon shaft 22 and secured in position by means of set screw 26, the collar being provided with a projeetion'27, (Figs. 4 and 6).

. For the purpose of Controlling the operation of bolt by means of knob 24 I have provided permutation looking meohanism supported as a whole by cross members 30 extending between front and rear plates 1 and 2, (Figs. 4, 7 and 8). Journaled in these cross members 30 I have provided. a shaft 31 mounted in a cut-out portion `of the cross members and secured therein by blocks 32 i which in turn are held in position by suitable means such for example screws 33 passing through cross members 30 and engagingV blocks 32.

Mounted -upon this shaft 31 I have provided. three lock- ing discs 34, 35, and 36, respectively, operating in looking notches 37, 38 andl 39 of looking 19, (Fig. 7). Each of these-looking discs is provided with a cutoutfportion 40, 41 and 42 respeetively, of just sufficient width and depth to permit the passage of looking bar 19 therethrough, as will be seen from Figure 8; It is clear that in order to operate the bolt by means of handle 24, looking discs 34, and 36 must be lined up so that their openings 40, 41 and 42 are y in registry with looking bar 19. When this is the case the looking discs will not interfere with the operation of looking bar 19 andthe bolt may be withdrawn as already described by turning knob 24. lf the looking discs are not in registry as described,'movement of the looking bar 19 cannot take place and consequently-ihe bolt cannot be withdrawn by operation of knob 24.

in order to permit the rlining up of the looking discs with their openings in'proper registry I have provided three ratc- het discs 43, 44 and 45, one for each of the looking discs and suitably sccured thereto by means Vof screws 87, 88 and 89. rfhe ratchet discs 43, 44 and 45 are provided with rachet teeth as will be seen by reference to Figures 5, 8 and. 9 adaptcd to be engagcd by pawl members 46, 47 and 48.

Mounted uponthe shaft 31 are three discs towardcits ratchet wheel by suitablesprjings such as is shown atV 54 in Figure 8 respect-ively and each of the discs is provided on the opposite side with outv-Jardly 'extending arms 61, 62 and 03 projecting through the face plate 1, whichis provided with suitable slots 64, 65 and 66 so'that arms (31, 62 and 634 may be depressed to operate the rat-Chet Wheels and thereby rotate the looking discs. Spring men'ibers 70, 71 and are provided secured to the rear plate 2 and arranged to exert pressure on pawl members 46, 47 and 48 en the opposite sides of the pivot so as to maintain 'the pawl members normally out of contact with the teeth of the ra-tchet members so that the ratchet discs mayr be rotated in the opposite direction to that imparted by the pawls by means to be. described here-fv after. The arrangement of spring members 70, 71 and 72 1s such thatidownward movement of the arms 61, 62 or163 causes upward movement of the pawl mechanism which.

looking disc may be turned through any number of degrees desired, each' independently of the other.

Referring now to FigurelO I haveshown a modified form of ratchet disc which hasv certain advantages 'The ratohet disc-45' fia e d the locking bar.

is shown as having three timjesthe number of teeth as on ratehet disc 45 whereby a com-l plete downstroke of arm 63' will moveV ratchet disct' through a distance of three teeth. For the purpose of utiliziiig the -advantages which this Construction makes possible, I have provided three notches 119, cut

in each of theslots 64', 65' and'66'and'acooperating ridge or proJection 120 on each of 'the arms 61', 62', and 63'. Eachr arin may therefore be operated either 'one-third or two-thirds of a stroke or adeoinplete stroke, thereby movingl the ratchet disc 'and the looking disc over a distance of one, two or three i'atchet teeth, which greatly increases the number of. possible permutations obtainable.` r l V f V 1 From the foregoing it will be understood thatthe position of the looking discs may be controlled by thejoperation of 1 arms 61, 62

and 63. It will also be understood that when the lock is set to zero, or in otliernwords', when lall of the looking discs have aV predetermined' position with reference to each other, andto looking bar 19, the discs may be rarranged with their openingsgin registry With the looking bar to permit opening'l the lock, by operating each 'of thel arms the numberof times required to move the par- Vticular'locking disc controlledthereby into a position such that its opening registers with the looking bar. Somemeans must be provided for'setting the lock to zero or starting position so thatl the proper number of operations of each of the arms will-cause'the openings in the looking discs to register With described.

Referring particularly to Figure Ihave shown three discs 75, 76 and' provided with gear teeth. around their f peripheries..

i Eacliof these discs-'hasasection of its teeth cutaway as at 80 as will be more particularly seen from Figure 1.` Eachv of the looking discs 34, 35 and 36 is provided with arow Vof holes 81,82 and 83 (Fig, 9)l adapted toV receive pins 84, 85 and 86 (Fig. 7) which extend through gear discs 7 5, 7 6 and77 into the loc- king discs 34, 35 and 3,6, thereby fixing the position of thelocking discs with reference to thegear discs., The number of operations ofl arms 61, 62 and 63 which will be required to set the looking discs withtheir o'penings in registry will depend upon the relative position of gears 75, 76 and 77 with reference to their looking discs 311, 35 and 36, as 'will be `more clearly explained hereafter. The entire ratchet, looking disc, and* gear disc assembly is secured in properposition upon the 'shaft 31 by means of a washer 90 interposed at one end between geardisc' 77 and support 30 and spring 91 interposed at the other end of shaftl31 between disc 58 and `|support 3'0 Spacer members suchfifas wasliers 92 be'interpos'edfibetweenthe uponshaft 96 at'one end thereof I These means will now be.

discsasl desired. For engagement with'the gear Vdiscs 75, 76 and 77 I have provided three gear 'discs 93, 94- and 95 (Figs. tand 9) mounted upon shaft 96 and suitably secured thereto as by keying so as to berotated by the rotation. of shaft 96. Shaft 96 is carried in a suitable yoke member 97 pivotally supported as at 98 from rear plate 2 and providediwith anv arm 99 extendingthrough the slot' 100 in the face plate 1. To prevent ac- 75 cesslto interior of the looking,mecha-r v nisin a. sliding plate 101 may be provided en- 'I gaging or surrounding member 99 and iressed against the rear of face plate 1 by a suitable spring 102. To maintain the -yoke 97 in proper position a supportll03 (Figfl) i may be provided securedl to support 30 and provided 'with a projection adapted to prevent yoke'97 from moving too far and havingrattached thereto'flspring means '104 for.

biasing gears' 93,r 941- and r95'out of engagement with gears 75, 76 and 77, nMounted have provided a bevel gear 105 adapted to be operated I by a second bevel gear 106 mounted u'ponshaft 107 provided with a thumb nut oi' other operating means 108 in front'of the face plate 1. V i

Fromthe foregoing it will be understood -A that rotation of thumb nut 108 willfrotate gear 106 andfthereby gear 105 which-will in turn Vrotateshaft 96 and gears93, 94- and If arm-99'is pressed upwardly against the action of its spring bias, gears 93, 94V and 95 may be engaged with gears 75, 76 and 77 andveach 'of these lgears will therefore be rotated until 'the-blank section or themutilated portion f of the gear. disc-hasjl eenV Vbrought into engagement With geai's 93, 911

'It is sometimes possible for expert thieves' V sure upon Vthe knob in afdirection to with- V whenthe looking disc oponings are iii registry `with the looking bar. To prevent the possibility of alock according to my inventiion being opened in this thorized persons I have provided-means for way' by-j unaupreventino'operation'of the arms 61, 62-an'd 63 or any one of themV whenever pressureis applied against dhandle 24%: in a direction tov withdraw the bolt. As a matter of fact it .is=necessa`ry to turn handle 24- in the opposite direction to that requiredto withber 97 With 111 and 112 are provided on the rear of facer plate 1 for slidably mounting plate 109.

'Plate 109 is formed With a proiecting;` portion 113 adapted to be engaged by projection 27v en collar of shaft 22. ljlate 109 is like'wise i tcnding' proection 1111 adapted to be en,- gaged by suitable spring;I 115 which bi.- ases plate 10%) to the right as shown in F i gure (i.

In order to be able to opel'- ate tlr (31, S2 and 63 it is necessary to rotate handle 211 in a clockwise direction as viewed Figure 2 which causes projection 27 to e Wii-h the part 113 of plate 109 :ind force the plate to the left in Figure 6 until slots 110 are in registry With slots 64a 65 and 66. The arms 61. 62 and 63 may then bo operated to set the (:oml i natien and handle 2-1 may then be rotated in counter clockwise direction to withdraw the bolt.

'lle prevent rotation of thumb screw 108 in an improper direction I have provider ratchet member 121 mounted upon shaft 107a the end of which may be iiized in position by yoke member 128. A suitable spring member 122 is provided for engagement With ratchet member 121. For Vthe purpose of producing clicks which may servo as an indication When operating` the combii'iaticn of my lock in the dark I have provided three springe 116 mounted upon a cross member 117 secured to supportsV 30 and held'in position thcreon by yoke memher 118 secured to cross member 117 by any suitable means such as bolts.

The cmfistruction of a lock according to -my invention having` been described, it is believed.v that the Operation thereof Will be readily understood. Jtssuming that the bolt is in lockingflposition that the locking discs are ne. ner at ero position nor in unhr-cking;I position, if it desired to open the lock7 rm 99 Will he pressed upivardly to engage the carried on yoke mem- 'he `egears''carried on sha-ft 31. Rota" n of thumb nut 108 Will then rotate each. of the sr ars 7 5, 7 6 and 77 to a position Where the mutilated sections are lined up in rcgistry and directly opposite the grears 93, arena and 3G are secured to lQ'ears 75, 76 and 77 by pins 841, and 86 the lockingz; discs will be carried With the discs and will be arranged each having:` its opening' a certain distance from the lock i known 'how many operations of each of the arms 61, 62 and 63 are required to cause each ovided With arearwardly ei;-v

Similarly the other discs Will he rotated to proper position by the operation of'arms 62, and 63 after rwhich knob 24; may be rotated to ivithdrawthe helt. To roset the lock. it is only necessary to press arm 99to engagethe gears on yoke 97 With the gears on shaft 317 and rotate thumb nut- 108 to change the position of the locki; g; discs. i

lt Will be understood that if the combination should becomeknown to unauthorized persons 'the lock may be r'earranged to open to a different combination by' removing shaft 31,' disassembling the permutation mechanism and changing the position of any one of the looking discs' 3d, 35 and with reference to its, associated gear disc 757 76 and 77 orthe relation of'each of these. This may done simply by Withdrawing` pins Sea 85 and 86, Shifting the made. Without departing` from the spirit and.

scope thereof3 Will be apparent to those skilled in the art.
