Application illed April 26, 1909, Serial No. 492,426. Renewed October 5, 1910. Serial No. 585,518.

To all whom it may concern:

Be it known that I, Oas'oN J. .BriAnnsmL a citizen ofthe United States, residing 11i the city and county of Deliver and State of Colo-v rado, have invented certain new and useful Improvements in Keyless Locks; and I do declare the following lto be a full, clear, and exact description of the invention, such as i'will' enable otliei's skilled in the 1.117' t0 which it appertains to make and use the same, refereiice being had' to the accoi'npanying drawings', and to the letters and figures of ref erence marked' thercoinwhicli 4forni a part of this specification.

My invention i'elates to improvements in -keyless locks of the class set forth in my previous"Patei'it No. 866,567, dated September 17th,1907, and an applicatioi'i Serial No.4 "373,545, filed Mayiith, 190.7, allowed Sept.

esta, i908.-

My present inventionrelates to certain novel features of construction,- wliereby the 'mechanism disclosed -in my previous patent 'and application, is greatly snnplilied, all of 5 is a sectional view taken on the line 5 5,

Fig. 3. Fig; (3 is a fragmentary sectional dei .tail view of the lock showing one of the buttons in one of itsrelations with the other Y parts and o n a larger seale. This isasection taken on theline. 3 3, Fig. -2 looking in the direction ofthe arrow. Figs. 7, 8, '9, and 10- 9 9, and 10T-10, respectively, of Fig. (S, the button only being sectionized. Fig. 11 isa detail view ofthe catch with its spring in po` sition. Fig. 12 is a detail view of the spring.

Fig. 13 is al section taken through the case, illustrating one of the buttons when in its inactiveposition or when in the position allowing the revolving disk to enter one of the segmental slots or `recess thereof. Fig. 14; is a similar view showing the button when in a position after giving it approximately onethird of a rotation from the position shown in Fig. 13. In this viewthe button must be pressed downwardly in order to permit the revolving disk to move to the unlocked position. Fig. 15 is asimilar view after the button has been turned two-tliirds of arevojlution from the position shown in Fig. 13. When 11i the position shown in Fig. 1 5, the

button must be moved upwardly' in order to allow the revolving disk to move to the unlocked position. Fig. 1G isa view of .the spring shwii in Fig. 12, viewed in the direction of arrow 16, Fig. 12. Fig. 17 isa fragmentary section taken through the bottoni of the easing on the line 17-17 of Fig.

5 cutting the button-holder, thc parts being shown on a larger scale.

The saine reference characters indicate the same parts in all the views.

. Let the numeral 5 designate the case which as shown in the drawing is circular iii shape and composed o f a bottom plate G and a surrounding flange 7 extending at right'angles to the bottom. The upper edge of the case is reces-'sed to forni an interior shoulder 8 upon which the cover 9 rests. The parts of the lock are held in operative relation by a center rivet 10.

Surrounding the rivet 10-in the bot-toiii of the case is a. washer 12 and also surrounding the rivet above the washer `12 is a second 'washer 13 which is surrounded by the button holder 1l, consisting of a plate having a central perforation in which the washer 13 tits and having-openings 15 through which pass the extremities of a number of buttons 1G which extend trai'isversely through the case of the lock. The portions 17 of these buttons which pass through the openings 15 are triangular in shape. The openings 15 have circular portions 18 which when en gaged b v lthe parts 17 of the buttons, allow the latter to turn freely. Communicating with the parts 1S of the openings 15 are parts 1.) in which the portions 17 of the buttons are adapted to fit closely, -whereby the buttons when engaging the parts 19 of the said openings are locked aga-inst rotation; IVhe'ii the parts of lthe iock mechanisinfare ,assembled and in their normal position, the

parts 19 of the openings 15 are engaged by 'the triangles 17 of the buttons, whereby the latter arelo'cked against rotation. The button holder is held in ich'normal position 4by a 11p 20 projecting `slightly downwardly from the bottoni of the said holder and av AILLB Cogli engaging a shallow recess 21- formed in the adjacent surface of the bottom of the case.

When it is desired to change the combina.-

tion, which is accomplished by givingone or more ofthe buttons 16 a partial rotation, the lip 20 of the button holder, is disengaged from the recess 21 by lifting the lip out of the recess, after whichthe holder may be turned to bring the circular portions 18 of theopenings 15, into the position to allow any button to be turned freely. After this is accomplished or after the pins have been properly adjusted, the button holder is returned to its normal position or that in which the parts 19 ofthe openings 15 engage ---v.--thet'iangular portions of the buttons and lock them i the button 20l outer edge with an upwardly projecting against rotary movement. The washer 13 issomewhat thicker than holder, to prevent the latter from being clamped or secured against movement when the parts are assembled.

.The button holder 14 is provided at lits 1P when the button holder is in the unposition, occupies a position in front opening 46 in the edge of the case to 4c which locked of the permit the entrance of the hooked extremity if Ithe user oi the 1s-perforated to outer extremity 30 of the hasp. This lip is so located that lock,` should forget to return the but-ton holder to its proper position after changing the combinatiomthe hooked extremity 30 of the hasp would perform this :function automatically as soon as the hasp is caused to assume the locked position, since as the' said` extremity of the hasp moves inwardly, it will engage the lip .4, and move ...the-button holder toward the right (see Figs. f 4 and 5), suiiieiently to cause the lip 20 to engage the recess 21 intheibottom of the case.

`. -Aboge the washerA 13and resting thereon is a third Washer 22 having a central openmg through which the rivet 10 passes.

Above the washer 22' and resting thereon is a spider spring 2 3 whose central portion receive-the rivet 10. From its centralportion spring Aarms 24 extend radially, Athe outer extremities ofthe said arms engaging circumferential grooves 25 in the buttons 16, whereby the latter' are normal] held in .a predetermined position with reference to'. the other parts of the mechanism.-

The central portion of the rivet 10 is enlarged as shown at 26 .and passes.v through a perforation 27 formed in a catch 28 whichispivotallymounted upon the rivet. The of the catch .28 is provided with a laterally disposed catchmember 29 adapted to engage the .hook-extremity 30 of a. hasp. 31, when position.

This spring is prothe' parts are in Athe locking vided with a li 36 projecting-into a re' ss 37 formed in t e pivotal extremity of. he catch. The member 34 of the Aspring has its outer extremity, located in such proximity to the catch member 29, that when the hasp is'in'the locked position, its inner extremity bears against the 'Springnembei-St and places the same under tension. At the saine' time the spring member 35 engages a lip 38 formed on a revolving plate 3S), the lip left or opposite the location of the haspexsition, the -revolvingvdisk 39, is prevented from moving toward theleft, by Virt-noot'` ithe 'position of oneor more ofthe buttons E16, which are so arranged that the arms'40 lof the 'revolving disk are'prevehted from entering anyone of the slots A., B and C formed in' each button. simply segment-shaped recesses. formed in the pin .and occupying three '/.ontal planes when the lock horizontal position.

BLE COPY ranged that if :the button is pressed downL Wardly, the last named slet will be brought into the plane of an arm 40 of the rcvolvmg disk allowing'the said arm to more intothe slot and permitting the disk and catch to moveto the unlocked position. In Fig. 15 Athe vslot C is so arranged that it the button is pushed upwardly a sufficient distance to an arm 40 of thereviolving disk into the plane ofthe slot (l, the arm 40 will enter the last named slot allowing the revolving diskand catch to more to the unlocked po` sition. e

' If two buttons of the set are in the relative positions shown ,in Figs. 14 and l5, in-

order to open the lock or release the hasp, it

will be necessary for theoperator to pressv down upon one of these buttons, namely, the

lone shown in Fig. 14, and upion the other button,namely, the one show in Fig. 15. Attentiongis called to the cover of the lock case is provided with openings 4l through which the upper extremities i 42l ofthe various buttons protrude; while ties 44 of the buttons protrude. Both ex- -the bottom of the case is provided with openings 43 through which the lowerv extremi' tremities 43 and 44 of the various buttons,

. protrude a sufficient" distance beyond' the case, toallow for the convenient manipulatipn' ofthe buttons by -upward or plownward pressure upon their exposed extrei iities, and

while the other two must be Amoved up-` wardly or vice versa. From this it will be understood .that therearea great many dii"- ferent possible combinations obtainable by adjusting the eight. buttons in question.

Attention is called to thev fact that .the

buttons A.are held in their. normal l'iositio'n byvirtue` of the engagement' of the spring arms .24 of the spider spring 23. .'lhese spring arms also serve to return the buttons to their normal position, after theyA have been are engaged-by the revolving disk in order pressed in either direction forunlocking purposes, that is to .sa-y after the slots ywhich act that the to allow.A 1t to move to the unlocked positiom' meritofthe revolving dislL/ The revolving disk is also provided withan interiorly projecting lip 45,` which enters arecess 3 formed in theouter .end-of the catch 28.

Imcated-abov'e the ievolving disk '39 but separated therefrom, is a washer 54.which rests upon a shoulder 55 formed upon the center rivet 10, whereby the washer is spaced from actual contact withthe revolving disk, thusfpreventing the clamping of the moving parts of the mechanism to interfere' with their proper movements.'when the parts are assembled. It. must be 4understood that the center rivet 1s upset or riveted at both ends in order to make it impossible to `gain access to the lock when the ,latter is in use.

rl`he mechanism is soV constructed -that after 'the lockis completed and the center rivet secured by upsetting its 'opposite exf' -,tremii.ies as shown at 56 andl 57, there is no necessity for gaining access to theinterior of the caseso faras -the use of the lock concerned, except for changing the combinatiomand this is accomplished by inserting a small instrument as a knife bladeor.n

small screw driver, into the hasp opening 46 in the edgeof the case, inv order to disengage the lip` 2O from-the recess 21 formed in the bottom of the case, in order to move the button holder sufficiently in the direction ofthe arrow in Fig. 5, to bring the triangu ar portions 17` of the buttons into the circular parts 1'8 of the openings 15in l theV button holder. 4After this is done. the= reo - 1 rf sinfrflttwim G y.

tion, by virtue of the fact'that the but-tons where they pass through the buttonholder-l are triangular' in cross section. In order f that the operator may understand when the necessary movement is given any button, l for changing the combination,tl1e prilitruld'v ing extremity of the button on one s'ide oi the ease herein designated the top, is pl'ovided with three radial marks 1 equidis-- tantljv located. Also arranged on top of the disk, is a number of dots or marks toward one of which, one of the radial'marks of each button always points. rl`hese marks designated `l and lare to enable the operator to know when he has moved a button far enough to change the .com bination. H e'nce. in turning any button for the.afore said purpose, the operator will move the same untilthe mark 1 next in the rear is brought into line with the mark 2 on the Acase or until the second mark next in the rear is caused to point toward the mark 2. In either (aise, the button,wi1l bev adjusted sutiicicntly to change the combination.
