KEYLESS PADLOCK.

Specification of Letters Patent.

Patented April 27, 1909.

Application iled May 14, 1907. Serial No.' 373,546.

T 0 all w/om it may concern:

Be it known that l, ORSON J. BLAKEsLnY, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Keyless Padlocks; and I .i

do decla-re the following to be a full, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to makel and use the same, reference being had to the accompanyf ing drawings, and to the letters and hgures ol reference marked thereon, which form a part of this specification.

My invention relates to improvements in keyless padlocks of the class set forth in my previous application Serial No. 27 4,060, filed Aug. 14th, 1,905, allowed July 24th, 1906, renewed Jan. 26th, 1907, Serial No. 354,316, allowed Feb. 25th, 1907, now matured into Patent No. 866,567 dated September 17, 1907.- My present invention relates to certain novel features of construction whereby the mechanism is greatly simplified and also whereby certain novel features of construction are embodied notably the means for changing. the combination of the lock, by

simply giving a partia rotation to one or more of the spring-actuated pins which 'are employed to secure the locking disk against movement when the mechanism is inthe locked position.

The invention will now be described in detail reference being made to the accompanying drawing in,z which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a view of my improved padlock with the outer ortions of the cap and locking disk remove( the parts of the said cap 'and disk which protrude into the casing, being shown in section. Fig. 2 is a section taken on the line 2 2 Fig. 1. Fig. 3 illustrates one of the spring-actuated locking pins shown in three diflerent positions. Fi 4 is a detail view of the latch which ho ds the shackle or bolt in placel when the mechanism is in the locked position. Fig. 5 is 'a detail View of a, spring applied to the latch and coperating therewith. View of the entire lock shown normal size. In the other views thc mechanism is shown double this size. Fic. 7 is a view of the lock with the cap and locking disk iartly broken away, the poyi/o'ns of the said parts which Figisav project into the lock casing being scctionized. Fig. 8 is a perspective view of the vcap plate. Fig. 9 is an interior view of the locking disk. Fig. 10.is n'sectional view of the same. Fig. 11 is an interior detail view ofthe guide rin for the locking pins. Fig. 12 is a sections. view of the same. Figs. 8 to 12 both inclusive are on the same scale as Fig. 6. Fig. 13 is a section taken on the line 13-13 Fig. 6, the parts, however, being shown on alarger scale. Figs. 14 and 15 are fragmentary top views with the cap plate removed and showing the locking disk in two positions, Fig. 14 showing the said disk at its limit of movement toward the right, while Fig. 15 shows it at its limit of movement toward the left, the pin 47 serving as a stop in both dire'otions.

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

Let the numeral 5 designate the lock casing and 6 a cap provided with interiorly projecting lugs 7 having notches 8 adapted to interlock with pins 9 forl holding the cap in place. Vhen this cap is inserted and given a partial turn so that the recesses 8 engage the pins 9, it is held securely in place. One of these pins is located in close proximity to the shackle opening 10 (sce dotted lines in Figs. 1 and 7),

so that one of the lugs 7 before its recess 8 engages the pin 9, partially closes the shackle opening 10. When, however, the cap is given a partial turn to cause the recesses 8 to engage the pins 9, the shackle ropening is free. From this it results that when the shackle is in placfyor in the locking position, the cap cannot be removed since it cannot be given the necessa y partial turn to releaseits lugs 7 from the .pins 9. The cap 6 is also provided with an additional lug designated 12, which is not'i'eeessod and occupies a osition between two of the locking pins Fig. 1), there, being snilicient space between the lug and the pins to permit the necessary movement; of the cap for locking and unlocking purposes.

Within thel lock casing is located a disk 13 hold in place by a central post 14 having a shoulder 15 which engages the disk 13. This post is provided with a reduced part 16 passing through an opening in the disk, the outer extremity of the post being enlarged and countersunk within the casing as shown at 1.7. lhe disk 1S has a circular flange 18 formed concentric with the/outer wall of the see/ ' with the flange 18 as well 'interposed between the disk 13 and the bottoin 23 of the casing 5. The disk 22 proljects outwardly beyond the flange 18 of the disk 13, and its flanfre 21A is concentric as with the outer circular wall of thc casing. The springs. 19 normally hold shoulders 24 lof the pins 2() against the inner surface of the'flange 21^ thus limiting thc outward movement of the ment with the flange 32 of the v the locking disk.

I locking I'disk 33. This with slots 34 in which the reduced part 29 of 38 adapte the shackle 36.

-extremity pins. Each pin 2O is also provided with an inner shoulder 25 which is normally held in engagement with the inner surface of a flange 26 termed on a guide ring 27. This flange is slotted as shown at 28 to receive the reduced parthZQ of each pin, the said .part being lo- `cated between the shoulder .25 and a shoulder 3() loeat'cd at the inner extremity of the head or the portion of the pin protruding beyond the outer wall oi the lock casing; This reduced part 29 is formed fiat on two opposite sides and is adapted to slide freely in the slots 28 of the flange 26 of the guide ring. As shownl in the drawing the reduced part 29 is provided with .two recesses 31 located in its opposite edges, the said recesses 'being staggered or out of alinement.

Outside of the guide ring 27 and concentrically arranded with the flange of the latter, is an interiorkly protrudin flange 32 of the the pins 20 reciprocates. l/Vhenthe pins 20 are so arranged that the uppermost series of slots 31 register and are arranved in alinelocking disk, the latter isallowed to move suiciently to 'permit the latch 35 to turn far enou h on the post 14, to unlock the shackle or bo t 36 and allow it to move through the opening 10 of the lock casing. .When the mechanism is in the locked position, one or more of the pins 20, is normally held in such position thatI its uppermost notch 31 is out of register with the corresponding notches of the other pins, and also out of register with the flange-32 of This. prevents the movement of the disk, and consequently holds the latch, 35 in the locking osition with referenceto the shackle 36. his latch is pro- -v'ide'd at its inner extremity with a'sleeve- 37 which surrounds the post 14. Its outer extremity is rovided with a hook-shaped part (l) to enga e the hooked part 39 of A eaf spring 40 is applied to the latch, the said spring having its inner l? rom this part. 41, two separated arms 42 'and 43 extend outwardly on opposite sides of ,the shackle 36.

ange is provided 41 shaped to fit the sleeve 37.`

the arm 44 of the latch. The member 43 of this spring is engaged on one side by a lug formed on the inner surface of the locking disk 33. This lug normally holds the latch 35 in the locking position with reference to The spring member 43, however, is under sullicient tension to exert considerable pressure on the l'ug'45, whereby there is a tendency to impart a rotary movement to the locking' disk. This movement, is impossible by reason of the fact that one, or more, of the pins 2() is in such position that its recess 31 is out of register with the flange 32 of this disk. [n the drawing 'lour of the pins 20 are so adj usted that their recesses 31 are normally out of alincmcnt with the flange 32. These pins are for convenience designated A in Fig` 1. The other pins are so adjusted that the inner recess 31 is t-he flange 32; while the pins A are sondjusted that the outer recess 31 of cach isVV uiperinost and consequently normally out oi alinement with the flange 32. ly turning these pins 30 any' desired rombination may be obtained as will be readily understood.V Now if we assume that the shackle 36 is in the locked position, ilt we wish to unlock the mechanism, the user will press inwardly on the four pins designated A, until the recesses 3l are in register with the corresponding recesses of the other pins, and"consequently in alinement with the flange 3; of the disk 33. As soon as this occurs, the tension or pressure of the spring member 43 acting on the `lug 45 of the locking disk, moves the said disk sufficiently to allow the'latch 35 to turn on thel post 14 far enough to release the shackle. ner extremity 39 of the shackle 36, when in the locking position, exerts a constant pressure on the spring member S42, wherebyv thev tendency of the latch is to move to the unlocked position. shackle on the spring member 42 that iinparts the tension to the member 43 which acts on the lug 45 of the locking disk.

The shackle 36 is provided with an en-l larged extremity 46 liavlng a pivot 47 which engages a bearing 48 formed in the circular flange of the casing. This pivot is loose in the part 46 and its inner portion be ond the hearing 48 is cut away to receive an support the top plate 6 of the casino'. This p holds the pivot pin in properp ace and `in ops erative re ation with the shackle. In the tremity of which is made fast to the head or enlargement of the shackle while the other l extremity 50 bears against the inner wall of the casing. This spring is`so arranged that it has a tendency to throw the hooked extremity of the shackle outwardly. In. other words as soon as the latch isv actuated bythe It will be understood that thev in ate It is this pressure by thel ,the shackle, the latter is pressure on its spring member 42, to release automatically thrown outwardly or tp the unlocked position shown in Fig. i. shackle head 46 which protrudcs into the casing, isprovided r. ith a cam 5i `.-hich as the hooked extremity oi vthe shackle is `thrown"outwardly, acts on a projection 52 formed on the outer extremity ol the latch 35, and returns thc latch to the lortkingT position, or in such position that its locking hook i as the latter is lorced into the casing.

'38 is in the path ol' the shackle extremity S) 'lhe part 520i the latch is provided ..ith a recess 58, into which protrudes a` lug 53 formed on the locking plate 33 and in reality constituting a part of the recessed [lange 32 of this disk. This flange, however, is cut away between its extremity 54 and its extremity 55 with the exception of the projection 53, in order to make room for the movement of the shackle head and the latch. This projection is necessary, since the locking plate must bc actuated simultaneously a ith the movement imparted to the latch 35 bythe cam member 51 of the shackle, in order to bring the reobeses 34 of the lockingr plate back into aline- Ient with the reduced parts 29 of the variious lockingpins, so that the pins u hich have been presse inwardly to unlock the mechanism, may return to their normal position as S0011 as the pressure thereon is released or ceases to act. Hence by virtue of the Incchanism just described, both the latch and the lockin plate, as soon as the pins A are pressed inwardly as hcrctofore explained, are rst moved automatically toward the left referrillg to Figs. 1 and 2 suiliciently to release the shackle, and immediately thereafter returned to their normal position by the action of the cam member 51 of the shackle. Then as the pins A are released, they are thrown outwardly by their springs, whereby the re- .dlfced or flattened parts 29 of the pins located inward from the notches 31, engage the flan e 320i the-,locking plate and hold it in theocked position. 'l'hen--as the shackle 36 is pressed inwardly, the cam 5l is moved away fr( 1 the part 52 of the latch whereby the latter when acted on by the entering extrelnitv 39 of the shackle, is allen ed to move toward the left sufficiently to permitI the shackle to enter, after `which its spring; returns it to engagement n ith the shackle whereby the latter is retained in the locking position. The guide' ring 27 is provided with. recess 56 in its periphery, to snake room for the head of the shackle whereby the latter is allowed to move freely.

The Han e 18 of the disk 13, is cut away Where the atch is located, and in one of its extremities i-'s formed a recess fwhich re ccives the member' 42 ofthe sprin 40. .This same extremity of the iange 18., a so forms a stop for the' latch during its movement torlhe portion ol' the v. ard the right, under the inlluence ot' the cam 51, thus preventing the latch from .moving;v l'artlnr than i.r4 necessary, as it might other..ise do by virtue ol` the momentum imparted bythe quick action ol' the cam portion ol. the shackle.

lirom the foregoing description the use and operatii'in olmy improved lock will be readily understmid. Assuming; that the paris are assembled, and that the I'onr pins A are so adjusted in the casing that their outer recesses .31 are uppermost (relerring to the cap ti as the upper side olthe lod-:hand that the other pins are so adjusted that the inner recesses 3]. are uppermost and in alinement with the ilang'e .'32 ol' the lockingl plate; and also assuming, that the shackle is in the locked position as shown in Fir. 7; it' it is desired to unlock the shackle, the lourpins A are pressed inwardly by the operator until their recesses 3l are in alinement with the llangre 32 ol' the locking disk, in which event the latch spring 4t) acting on the lui-g' 45 ol' thc locking` plate, imparts a partial rotary movement to thc latter toward the lel't, and a corresponding movement to the latch, the movement oi' the latter being suflicient .to release thc hooked extremity ol' the shackle, in which event the latter is automatically thrown outwardly to the )osition shown in Fig. 1, by its spring 49. As t e shackle moves outwardly, its cam portion 5l acts on the part 52 f the latch and returns the latter to the locking position, whereby its locking` extremity 38 is located in front ol' the opening; 10 for the entrance of the shackle` The locking )late is simultaneously given a corresponding movement, since the part 52'ol` the latch as it movestoward the right, acts onthe lug or projection 53 ol' the locking plate. ,This aetlon of the locking' plate brings the recesses 34 lof its ilange back into alinemcnt with the reduced' parts 29 olI the locking pins, and allows the pins A to move outwardly as soon. as the pressure thereon is released, 'thus bringing the parts ol' the pins A, located inward l'rom their recesses 3l, into position to retain the locking,- plate as efell as the latch, in the locking` position, alter the shackle has been actuatet to disengage its cam l'rom the latch, lor in other words alter the shackle has been returned to the locking position. The lug 12 ol the cap 6 reaches the bottom ol' the 'case and l'orms a support l'or the cap, thus eooperating with the shackle pivot in this regard. r

-The notched cooperating extremities 3S and 39 ol' the latch and shackle, are so arranged that bypullinfbr outwardly on the shackle, there is no tendency to impart a Ilateral or circular thrust to the locking disk locking disk, the latter would be thrust more tightly against the pins A, thus enabling a person wishing to open the lock, to know which pins 'to push. Attention is also called to thc fact that the locking disk 33 is provided with a recess 5S which the enters when the' parts are assembled. This pin l'orms a stopto limit the movement of the disk in both directions when the device is operated as heretofore ex lained. This is impcr'tanlsince the disk w en returning to its normal or locking position must not vary in its movement since the recesses 34 must always bc in exact alinenicnt with thereduced portions ol' the locking pins, otherwise the said pins could not be operated` neither could the actuated )ins return to their normal position under t e influence oi' the spring alter being pressed inwardly to unlock the device.

The outer extremities oi' the pins 2U are slightly reduced in diameter, to prevent them from rubbing on the case, since this rubbing action might indicate the pins to be pressed in unlockingthe device. lt may also be stated that il' any pins besides those arranged to be pressed to unlock the mechanism, are actuated the only result would be to lock the mechanism more securely.
