(Cl. 70-21) ABSTRACT OF THE DISCLSURE A padlock incorporating both combination and keyactuated mechanisms, employing a locking bolt engaging 'and locking a padlock shackle member against release. A gate vane member is pivoted on the locking vbolt and abuts against combination discs to prevent unlocking movement of the bolt. Alignment of gate notches in the combination discs to receive the vane member releases the locking bolt and the padlock shackle member and a key mechanism rotates the vane member out of abutting position to release the locking Ibolt and shackle member.

This invention relates in general to locks, and more particularly to an improved padlock construction incorporating both combination and key-actuated mechanisms.

Padlocks, as heretofore known, were usually constructed for operation either by more or less conventional keyactu-ated mechanisms, or combination controlled mechanisms. Such padlocks were excessively complicated and expensive to manufacture, and lacked the desired strength, durability, and security.

It is accordingly a principal object of this invention to provide an improved padlock employing both combination and key-actuated mechanisms, by which such padlock can be alternatively operated either by a combination controlled mechanism or by a key-actuated mechamsm.

It is another object of this invention to provide a padlock mechanism of improved strength and security.

It is another object of this invention to provide an improved key-actuated padlock.

It is still another object of this invention to provide an improved combination operated padlock.

It is a further object of this invention to provide a padlock of generally improved design, operating characteristics, and durability.

These and other objects, advantages .and features of novelty will be evident hereinafter.

Apparatus Referring rst primarily to FIGURES 2-7, the principal enclosing body elements and external components of the apparatus of the invention are:

A hollow, drum-shaped lock case, shown generally at 10, comprising an inner, hollow, generally cylindrically-shaped, open ended, rigid metal lock chassis 12; a generally cup-shaped, sheet metal inner case 14, closely fitting around the lock chassis 12 and having a circular front opening 16 and a removable, disk-shaped, metal back closure plate 18; an outer, relatively thin, sheet metal cover 20, formed on the front side thereof coaxially of said opening 16 with a slightly raised, annular escutcheon portion 28, with a coaxial circular dial opening 24 therein, and on the backside thereof having a relatively thin, sheet metal, disk-shaped cover 26, retained thereon by means of crimping the edge 20 of sheet metal cover 20 around the back edge' of the disk-shaped cover 26; a generally U-shapedy shackle y30, having a pair of parallel,

shackle arms

32 and 34 which normally extend into the lock case 10 through suitable shackle arm openings formed at 36 and 38 in the upper edge thereof; a combination dial 39, including a dial housing 40 rotatably supported in and extending externally from the circular opening 16 in the front side of the inner case 14; and a key-operated, cylindrical lock 42, the outer key-slotted end 44 of which extends through an aperture 46 in the outer end 48 of the dial housing 40.

Referring next in more detail to FIGURES 2 and 4-l0d, the lock chassis 12 is formed on the interior thereof with an integral, inwardly projecting, shackle guide 50, having a shackle guide bore 52 extending vertically therethrough and coaxially joining `at its upper end the beforementioned shackle arm opening 38 in the upper edge of the lock case 10. Vertically, slidably supported within the shackle guide bore 52 is the inner end portion of shackle arm 34 of the shackle 30. The inner lower end portion of shackle arm 34, contained within the shackle guide bore 52, is formed with a flattened side 54 and on the lower end with a stop knob 56 of the same outside diameter as the shackle arm 34 and joined thereto by a short necked section 58 of reduced outside diameter. A stop pin 59 extending crosswise through the shackle guide 50 and intersecting the edge of shackle guide bore 52 adjacent its upper end and opposite the flattened side 54 of the shackle arm 34 serves to limit the axially outward movement of the shackle 30 by engagement with the upper annular surface 60 of the stop knob 56. When positioned at its extreme axially extended position, with the stop pin 59 in the short necked section 58 adjacent the upper annular surface 60 of the stop knob 56, the shackle 30 may be rotated to any desired angular position about the longitudinal axis of shackle arm 34.

The opposite shackle arm 32 of the shackle 30, when in the closed, locked position, as best illustrated in FIG- URE 2, extends into the upper edge of the lock case coaxially through the beforementioned shackle arm opening 36. The lower end portion of the shackle arm 32, which extends into the lock case 10 when the shackle 30 is in its closed, locked position, as shown in FIGURE 2, is formed with a laterally facing lock notch 62 adjacent the lower end thereof, having opposite, upper and lower, laterally divergingly

beveled surfaces

63 and 64, and the lower end of the shackle arm 32 is formed with an inwardly, downwardly sloping projection 65, sharing the upper beveled surface 64 of the lock notch 62, and bounded at the lower end thereof by beveled surface 66,

surfaces

64 and 66 being substantially parallel with one another. Fixedly attached to and extending perpendicularly inwardly of the back closure plate 18 is a bolt lever pivot pillar 68, and rotatably supported in an opening 70 in the back closure plate 18 is a combination disk assembly supporting and key-actuating shaft 72, which shaft 72 and the disk assembly supported thereon will be hereinafter more fully described.

The rearward end of the bolt lever pivot pillar 68 is secured to the back closure plate 18 by means of a reduced diameter shank portion 76 thereof, which is pressed through a chamfered hole in the back closure plate 18 and upset at its end as best shown at 78 in FIGURE 5. The bolt lever pivot pillar 68 is formed with a base portion 80 of increased diameter, thereby forming a forwardly facing annular shoulder 82. Pivotally supported on the bolt lever pivot pillar 68, forwardly of the annular shoulder 82, is a generally L- shaped, locking bolt lever 84, the locking bolt lever 84 being provided with a bearing bore 86 adjacent its lower end, through which the bolt lever pivot pillar 68 supportingly extends. The locking bolt lever 84 is retained on the bolt lever pivot pillar 68 by means of an annular retainer collar 88, setscrew-fixed to the forward end thereof.

The upper, outer end portion of the locking bolt lever 84, is bifurcated to form a pair of spaced-apart, parallel, supporting members, as best shown at 90 and 91 in FIGURES 6 and 9, and such supporting members 90 land 91 are provided with a pair of coaxial,

pivot bearing holes

92 and 93, for receiving opposite pivot ends 94 and 96 of an upper crossmember 98 of a generally I- shaped gate vane member 100. The gate vane member 100 is thereby pivotally suspended from the upper, outer end portion of the locking bolt lever 84, with freedom for limited angular swinging motion. The lower end of the gate vane member 100 is formed with a crosswise-extending, rectangular shaped, gate dog 102 for engagement with gate notches in combination disks, as will be hereinafter described.

The intermediate portion of the locking bolt lever 84 is formed with shackle arm engagement means which includes a combined lock tongue 103 and shackle arm receiving recess 104, said lock tongue 103 having upper and lower

beveled surfaces

105 and 106 approximately matching in shape the beforementioned beveled surfaces 4 63 and 64 of the lock notch 62 in the shackle arm 32, and shackle arm receiving recess 104 having upper and lower

beveled surfaces

106 and 108 respectively, approximately matching in shape the

beveled surfaces

64 and 66 of the projection 65 on the lower end of the shackle arm 32.

Pivotally supported upon and positioned against the rearward face of the locking bolt lever 84 by means of a pivot stud 110, the shank of which is pressed into a drill hole 112 in the lower portion of the locking bolt lever 84 adjacent the bearing bore 86, is a vane catch lever 114. Torque is applied to the vane catch lever 114 relative to the locking bolt lever 84 by means of a coil spring 116, which encireles a portion of the pivot stud 110, with the upper extremity 118 of the coil spring 116 pressing against a laterally extending tab 122 formed on the pivot of the vane catch lever 114, and the opposite lower extremity of the coil spring 116 pressing against the base portion 80 of the bolt lever pivot pillar 68, thereby urging the vane catch lever 114 to pivot in a clockwise direction relative to the locking bolt lever 84, as viewed in FIGURE 2. The outer end of the vane catch lever 114, opposite its pivot end, is formed with a downwardly facing, hook-shaped vane catch 124, which includes a laterally extending catch tab member 126. The hook-shaped vane catch 124 is adapted to make hooking engagement down over the left-hand end of the gate dog 102 of the gate vane member 100 when the padlock is in locked condition, as shown in FIGURE 2, and when in unlocked condition, as shown in FIGURE 3.

As best shown in isometric FIGURE 9, the inner bearing end of the combination disk assembly supporting and key-actuating shaft 72 has an integral flange collar 130 formed with diametri-cally

opposite flats

132 and 134 which fit into a correspondingly shaped opening 136 formed through the central portion of a vane catch control cam carrier body 140. The vane catch control cam carrier body 140 is formed with a generally radially extending arm 142 which carries at its outer end a transversely extending foot member 128. The vane catch control cam carrier body 140 is also provided with a radially rising vane catch control cam 144, which terminates in a radially extending end portion 145, carrying a crosswise-extending control pin 146.

Coaxially supported upon the combination disk assembly supporting and key-actuating shaft 72 is a tubular shaped, combination disk-supporting hub 148, having at its rearward end an integrally formed radial fiange 150. A pin hole 152 is provided through the radial flange 150, which makes rotation-preventing engagement with a projecting pin 154 fixed in the back closure plate 18. The hub 148 is thus rotationally fixed relative to the back closure plate 18 and lock case 10, while at the same time providing freedom for rotational movement of the shaft 72 therein.

Coaxially supported upon the hub 148, between the forward end 156 thereof and the radial flange 150, are the following components of the combination disk assembly:

A spacer washer 158; a combination disk driver coupling member 160; a first combination disk 162, having a gate notch 163 in the edge thereof; a first spacer ring 164; a second combination disk 166, having a gate notch 167 in the edge thereof; a second spacer ring 168; a third combination disk 170, having a gate notch 171 in the edge thereof; and a Scrambler cam annulus 172, carrying a radially extending cam lobe 174. The first, second, and

third combination disks

162, 166, and are freely rotatably supported on the hub 148, 'but the first and second spacer rings 164 and 168 are nonrotatably supported on the hub 148, rotation being prevented by key pins 176 and 178 which project radially inwardly from the bores thereof into axially slidable Ibut rotation-preventing engagement with a longitudinal key slot 180 formed in the exterior surface of the hub 148. The spacer rings 164 and 168,

being thus rotationally fixed with respect to the hub 148, serve to rotationally isolate the several combination disks thereon, thereby, in operation, preventing rotational movement from being frictionally transmitted from one combination disk to the other.

The combination disk driver coupling member 160 is provided, intermediate its center bore and periphery, with an axially, rearwardly extending drive pin 182, which engages a correspondingly located pin hole 184 formed through the first combination disk 162. The first combination disk 162 is also provided, intermediate its center -bore and periphery, with an axially, rearwardly extending combination disk drive pin 186. The second combination disk 166 is similarly provided with circumferentially spaced-apart, axially forwardly and rearwardly extending combination disk drive pins 188 and 190, and the third combination disk 170 is likewise provided with circumferentially spaced-apart, axially forwardly and rearwardly extending combination disk drive pins 192 and 194. All of the combination disk drive pins, except drive pin 194; namely, drive pins 186, 188, 190 and 192, are positioned at equal radial distance from the centers of the

combination disks

162, 166, 170, such that upon imparting rotation to the

combination disks

162, 166, 170 relative to each other by manipulation of the combination dial housing 40, the adjacent combination disk drive pins 186, 188, 190, 192 will be moved into driving engagement With one another, such as to enable the

combination disks

162, 166, 170 to be rotationally positioned, relative to each other on the hub 148, in sequence and in accordance with a predetermined rotational angular relationship, as is well known in the combination lock art.

The most rearward one of the beforementioned drive pins 194, carried by the third combination disk 170, makes driving coupling engagement with a pin hole 196 formed through the Scrambler cam annulus 172, whereby the combination disk 170 and the Scrambler cam annulus 172 are rotationally fixed together.

Referring again tothe combination disk driver coupling member 160, this coupling member 160is provided with four, circumferentially equally spaced-apart, axially forwardly extending,

ycoupling tabs

200, 202, 204 and 206. One of the coupling tabs (for example, tab 200) is preferably wider than the others for the purpose of indexing it rotationally with respect to a disk shaped, combination dial coupler member 208, the inner face of which is formed with four

mating coupling sockets

210, 212, 214 and 216, as best shown in FIGURE 7, for respectively receiving the

coupling tabs

200, 202, 204 and 206, the coupling socket 210 being the widest, such as to receive the corresponding, widest coupling tab 200. The combination dial coupler member 208 is seated within a correspondingly sized counterbore 218 formed in the innermost end of an annular boss portion 220 of the combination dial housing 40 and is retained therein and nonrotationally coupled with respect thereto, by means of a radial coupling pin 222, as best shown in FIGURE 5.

The spacer washer 158 is rotatably positioned on the reduced diameter outer end portion 224 of the combination disk supporting hub 148, with the inner edge thereof in retaining abutment with the inner annular surface portion of the combination disk driver coupling member 160 and with the opposite outer surface thereof in retaining abutment with the marginal surface portion of the cornbination dial coupler member 208 immediately surrounding t-he coaxial bore 226 thereof.

Pivotally supported on a pivot stud 228, pressed fitted into a hole 230, in the lower portion of the back closure plateV 18, is a Scrambler actuator lever 232. The Scrambler actuator lever 232 is provided at the pivot end With a bearing hole 234, through which the beforementioned pivot stud 228 extends, and at the opposite outer end thereof the Scrambler actuator lever 232 is provided with the beforementioned, laterally extending, actuator foot 238. A spring retainer studv 236 is attached to an intermediate portion of the Scrambler actuator lever 232, and a Scrambler actuator spring 240 encircles a portion of the pivot stud 228, with one end portion 242 of the Scrambler actuator spring 240 bearing against the adjacent inner surface of the lock chassis 12, and with the other end portion of the Scrambler actuator spring 240 bent under the spring retainer stud 236 and extending outwardly along the side of the Scrambler actuator lever 232 into bearing engagement with a notch 244 formed in the inner edge of the actuator foot 238. The extreme outer end of the Scrambler actuator spring 240, which extends beyond the notch 244 in the actuator foot 238, is formed with a hook portion as shown at 246. In the operation of the apparatus as hereinafter described, the hook portion 246 of the Scrambler actuator spring 240 is adapted to move upwardly over and make engagement with the upper end 175 of the cam lobe 174 of the Scrambler cam annulus 172.

Referring next principally to FIGURES l, 6, 8a, and 8b, iixed eccentrically in a pocket 250, formed within the body of the combination actuator dial housing 40, is the beforementioned conventional key-operated lock 42. The outer key slotted end 44 of the key-operated lock 42 is exposed through the aperture 46 formed through the outer end 48 of the combination dial housing 40 and is provided with a key slot 252 for receiving a conventional key (not shown) for key operation of the key-actuated mechanism. Extending inwardly from the rearward end 254 of the lock plug 42, and connected for rotation by the mechanism therein, is a small externally toothed pinion gear segment 256, formed with a flat, untoothed side portion, as best shown at 258 in FIGURES 8a and 8b. Upon rotation of the pinion gear segment 256, from the position shown in FIGURE 8a to that shown in FIGURE 8b, the teeth 260 of the pinion gear segment 256 are moved from a position of disengagement, as shown in FIGURE 8a, into meshing engagement with teeth 262 of an annular, internally toothed gear 264, as shown in FIGURE 8b.

The internally toothed gear 264 is formed with an axially rearwardly extending hub portion 266 which is rotatably supported within the coaxial bore 226 in the combination dial coupler member 208. The hub portion 266 is provided with a squared central opening 268 which makes driving coupling engagement withV a matching squared outer end portion 270 of the combination disk assembly supporting and key-actuating shaft 72.

As hereinbefore mentioned, the combination dial housing 40 is rotatably supported within the circular front opening 16 formed in the inner case 14 and such rotatable support of the dial housing 40 is accomplished by the relatively short, coaxial annular boss portion 220 formed on its inner end, which extends coaxially through and is rotatably supported and retained in the circular front opening 16 by means of a thin, flat, annular, retainer snap-ring 272 which extends radially from a snap-ring groove 274 formed around the exterior of the annular boss portion 220, to a position bearing upon the inner marginal surface of the inner case 14 immediately surrounding the opening 16.

Operation The operation of the hereinbefore described lock mechanism is as follows:

When the padlock is in a normal, locked condition, the positions of the parts thereof are as shown in FIG- URE 2. Under such locked condition, the shackle 30 is in its fully retracted, closed position, with the lock tongue 103 of the locking bolt lever 84 in engagement with the lock notch 62 of the shackle arm 32, and the projection 65 at the lower end of the shackle arm 32 is in engagement with the shackle arm receiving recess 104. At the same time, the pivotable gate vane member is in the vertical position shown in FIGURE 2, with the lower end edge of the gate dog 102 thereof positioned adjacent to or in abutment with one or more ofthe peripheries of the

combination disks

162, 166 and 170, one or more of the combination disks being rotationally positioned upon the hub 148, such that one or more of the

gate notches

163, 167 or 171 thereof is out of engaging alignment with the gate dog 102.

The gate vane member 100 is retained in such vertical position by hooking engagement of the vane catch 124 and vane catch tab member 126 of the vane catch lever 114, over the right-hand edge of the gate dog 102, acting under the force of the coil spring 116. The resultant abutment of the lower end of the gate dog 102 of the gate vane member 100 with the peripheries of one or more of the

combination disks

162, 166 or 170 blocks any possible clockwise pivotal motion of the locking bolt lever 84 about the bolt lever pivot pillar 68, thereby retaining lock tongue 103 in locking engagement with the lock notch 62 in the shackle arm 32 and the projection 65 at the lower end of the shackle arm 32 in locking engagement with the shackle arm receiving recess 104 in the locking bolt lever 84. Extension of the shackle 30 to its extended, unlocked position is thereby prevented.

When it is desired to actuate the padlock mechanism to an unlocked condition, this can be accomplished in two separate ways; namely, either by key controlled actuation through operation of the mechanism of the lock 42 in the dial housing 40, with the resultant sequential movement of the parts thereof as illustrated in FIGURES a-10c, or by manipulation of the combination disk assembly mechanism by means of the combination dial 39 and dial housing 40 in accordance with a predetermined combination, with the resultant sequential movement of the parts thereof as illustrated in FIGURES 2, 3, and 4.

The unlocking operation of the padlock by means of the key-operated mechanism is as follows:

Upon insertion of the proper key into the key-slot 252 in the outer key-slotted end 44 of the lock 42, and upon rotation thereof in a clockwise direction, as viewed in FIGURE 1, the inner pinion gear segment 256 is caused to rotate from its normally inactive position shown in FIGURE 8a to that shown in FIGURE 8b, in which latter position the gear teeth 260 of the pinion gear segment 256 are brought into operative meshing engagement with the gear teeth 262 of the internally toothed gear 264. Continued rotation of the pinion gear segment 256 imparts rotation to the internally toothed gear 264, which is transmitted through the hub portion 266 thereof to the squared outer end portion 270 of the combination disk assembly supporting and key actuating shaft 72, which, in turn, acting through the flattened ange collar 130 thereof, rotates the vane catch control cam carrier body 140 in a clockwise direction, through an angle sufficient to bring the vane catch control `cam 144 into lifting engagement with the lower side of the catch tab member 126 on the outer end of the vane catch lever 114. The vane catch 124 and catch tab member 126 is thereby lifted from hooking engagement with the gate dog 102 of the gate vane member 100, shown in FIGURE 2, to the unhooked portion shown in FIGURE 10a. Pivotal restraint of the gate vane member 100 is thus removed and continued rotation of the vane catch control cam carrier body 140 eventually brings the control pin 146 thereof into engagement with the side of the gate dog 102, thereby swinging the gate vane member 100 from the position shown in FIGURE 10a to the sloping position shown in FIGURE 10b, in which latter sloping position the lower end of the gate dog 102 is removed from a position of blocking abutment with the peripheries of the

combination disks

162, 166 or 170.

The gate vane member 100 having thus been moved from a vertical position, as shown in FIGURE 10a, to a pivotally displaced, sloping position, as shown in FIG- URE 10b, pivotal motion of the locking bolt lever 84 is no longer blocked thereby, and the locking bolt lever 84 is therebyvfreed for pivotal displacement about bolt lever pivot pillar 68 in a clockwise direction. Thus, upon applying force of the shackle 30, tending to move it outwardly to an extended, unlocked position, such force is transmitted from the projection 65 at the lower end of the shackle arm 32 to the beveled surface 106 of the lock tongue 103, thereby pivotally displacing the locking bolt lever 84 from the position shown in FIGURE 10b to that shown in FIGURE 10c, thereby withdrawing the lock tongue 103 from the lock notch 62 and freeing the shackle 30 to be moved to its unlocked, extended position as illustrated in FIGURE 10c.

Following the before-described key-actuated unlocking procedure, when it is desired to re-establish the locked condition of the lock mechanism, force is applied to the shackle 30 in a direction to move it to its retracted position, and, in so doing, the lower beveled end surface 66 of the shackle arm 32 is brought into engagement with the lower beveled surface 108 of the shackle arm receiving recess 104, whereby, as a result of sliding movement between the beveled surfaces `66 and 108, the locking bolt lever 84 is caused to pivot about the bolt lever pivot pillar 68 in a counterclockwise direction from the position shown in FIGURE 10c, back to that shown in FIGURE 10b.

The locking operation is then completed by rotation of the key in the lock 42 in a direction opposite to that of the unlocking procedure; namely, in a counterclockwise direction, thereby imparting rotation, through the combination disk assembly supporting and key-actuating shaft 72, to the vane catch control cam carrier body in a counterclockwise direction sufficient to move the foot member 128 from the position shown in FIGURE 10b into engagement with the side of the gate dog 102, as shown in FIGURE 10d, whereby the gate vane member 100 is restored to its vertical position, followed by return of the vane catch 124 of the vane catch lever 114 into the hooking engagement with the gate dog 102, shown in FIG. 2.

The unlocking operation of the padlock apparatus by means of manipulation of the combination lock assembly is as follows:

Rotation of the graduated combination actuating dial 39 and dial housing 40 is transmitted through the radial coupling pin 222 to the combination dial coupler member 208, and thence through the

coupling tabs

200, 202, 204, and 206 of the combination disk driver coupling member 160, and thence through drive pin 182 to the first combination disk 162. Upon such rotation of the first combination disk 162 in a predetermined direction, the combination disk drive pin 186 is brought into driving engagement with the combination disk drive pin 188 of the second combination disk 166, which is thereby, in turn, rotated sufficiently to bring the combination disk drive pin 190 of the second combination disk 166 into driving contact with the combination disk drive pin 192 of the third combination disk 170, which, in turn, by reason of the combination disk drive pin 194 also rotates the Scrambler cam annulus 172 therewith. Following such rotation of the rst, second, and

third combination disks

162, 166 and 170, as before described, the combination dial housing 40 is then adjustably rotated in opposite, alternate directions sequentially through predetermined rotational angles as indicated by the combination dial 39, in accordance with the predetermined combination, as is well known in the combination lock art, which results in rotationally moving the combination disks on the hub 148 sequentially into such positions as to bring the

gate notches

163, 167, and 171 thereof into simultaneous axial alignment with one another immediately opposite and in engageable alignment with the lower end surface portion of the gate dog 102, as illustrated in FIGURE 4. The gate dog 102 is then free to move downwardly into engagement with the thus aligned

gate notches

163, 167, and 171 to the position illustrated in FIGURE 3, and pivotal motion of the locking bolt lever 84 is thus no longer blocked by thel gate vane member 100, and the locking bolt lever 84 is therefore free for pivotal displacement about bolt lever pivot pillar 68 in a clockwise direction. Thus, upon applying force to the shackle 30, tending to move it outwardly to an eX- tended, unlocked position, such force is transmitted from the projection 65 at the lower end of the shackle arm 32 to the beveled surface 106 of the lock tongue 103, as previously hereinbefore described, thereby pivotally displacing the locking bolt lever 84 from the position shown in FIGURE 4 to that shown in FIGURE 3, thereby removing the lock tongue 103 from the lock notch 62 and thereby freeing the shackle 30 to be moved to its unlocked, extended position as shown in FIGURE 3.

Upon movement of the shackle 30 to its extended, unlocked position, as shown in FIGURE 3, the stop knob 56 at the lower end of the shackle arm 34 is moved up into the shackle guide bore 52 to some such position as shown in dotted lines therein, thereby removing the stop knob 56 from restraining engagement with the actuator foot 238 of the Scrambler actuator lever 232, thereby, in turn, permitting the Scrambler actuator lever 232 to pivot in a counterclockwise direction under the force of the Scrambler actuator spring 240, from the position shown in FIGURE 2 to that shown in FIGURE 3, at which latter position the hook portion 246 of the Scrambler actuator spring 240 moves up over the edge of the Scrambler cam lobe 174 into a position of engagement with the upper end 17 5 of the cam lobe 174.

Following the beforedescribed unlocking operation of the apparatus by means of the manipulation of the combination lock assembly, when it is desired to re-establish the locked condition of the padlock mechanism, extended force is applied to the shackle 30 in a direction to move it from the position shown in FIGURE 3 to its retracted position shown in FIGURE 2. In so doing, the lower beveled end surface 66 of the shackle arm 32 is brought into engagement with the lower beveled surface 108 of the shackle arm receiving recess 104, whereby, as a result of sliding movement between the

beveled surfaces

66 and 108, the locking bolt lever 84 is caused to pivot about the bolt lever pivot pillar 68 in a counterclockwiseV direction, from the position shown in FIGURE 3 back to the position shown in FIGURE 2. The gate vane member 100 and gate dog 102 are thereby lifted upwardly out of engagement with the

gate notches

163, 167, and 171 of the

combination disks

162, 166, and 170, from the position shown in FIGURE 3 to that shown in FIGURE 2, thereby rotationally freeing the

combination disks

162, 166, and 170 for rotation on the hub 148.

In thus moving the shackle 30 from its extended, unlocked position, as shown in FIGURE 3 to its retracted, locked position, as shown in FIGURE 2,V the stop knob 56 is moved downwardly out of the shackle guide bore 52, from the position shown in dotted lines in FIGURE 3 into engagement with the actuator foot 238, thereby pivoting the Scrambler actuator lever 232 in a clockwise direction from the position shown in FIGURE 3 to that shown in FIGURE 2, thereby causing the Scrambler actuator spring 240 to pull downwardly through its hooked portion 246 against the upper end 175 of the Scrambler cam lobe 174, thereby imparting a snap-action rotational displacement of the Scrambler cam annulus 172 and the third combination disk 170 coupled thereto, thereby displacing the gate notch 171 from its previous alignment with the gate dog 102. The re-entrance of the gate dog 102 into any of the gate notches of the combination disks is thereby immediately precluded, thereby blocking any possible pivotal return movement of the locking bolt lever 84 from its locked to its unlocked position. Any immediately following unlocking of the padlock, without complete repetition of the combination manipulation, is thereby prevented.
