FRANK ELLIso BEST, or sEA TL fwAsnINeToN, ASSIGNOR To FRANK E. BEST, I o., or SEATTLE, WASHINGTON, A CORPORATION or WASHINGTON.
PADLOCK.
Application filed ul 2,
To all whom it may concern:
Be it known that I, FRANK. ELLisoN BEsT, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Padlock, of which the followingis a with the accompanying drawings.
In the drawings Figures 1 and 2 are views in perspective, respectively, showing my padlock housing and the pin'tumbler lock core that is adapted to fit into such padlock housing.
Fig. 3 is a sectional view through the padlock, parts being shown in elevation.
Figs. land are sectional views'on broken lines 4.: and 55 respectivelyof Fig. 3.
Fig. 6 is'a detached perspective view of.
one of the latch members used for locking the shackle. i 1 f Like reference numerals designate like parts throughout the several views.
In the drawings -8 designates a padlock housing of one piece construction having an integral top end 9 through which extends two bores 10 and 11 for the reception of a J shaped shackle having a longer. leg 12 and a shorter leg 13.
The recess for the pin tumbler lock mechanism is preferably formed by boring upwardly from the bottom of the lock, three parallel intersecting holes 14. and 16. The hole 14 is afterwards filled by a plug 17 and the hole 16 is partially filled by a plug 18. The holes 14, 15 and 16 overlap as shown in Figs. Land 5 so that they leave inwardly protruding ribs or ridges which contribute to form a recess in which a standard pin tumbler lock core 21 of figure 8 cross sectional shape may fit. we
In constructing the lock housing the holes 14 and 16 may first be bored and plugged 1924. Serial N6. 723,789.
and the center hole 15 and holes 10 and 11 for the shackles may then be bored'thus boring away the parts of the plugs 17 and 18 into which parts of the shackle legs and lock fit. i
The lock core 21 is provided on its inner end with a throw member or key stop 22 having outwardly protruding eccentric pins 23 and is further provided with a key controlled movable gate 25 arranged to be protruded from the groove along one side thereof to engage behind a suitable shoulder in oneof the ribs 20 and lock. the core 21 in the padlock housing. A face plate 26 is pro vided on the lock core 21 and is adapted to seat within'a recess 27 in the end of the padlock housing. To make it more difficult. to
insert an instrument alongsideof the face 3 plate and pry outwardly on the same or to otherwise tamper with the face plate I prefer to countersink the face plate substantially as shown in Fig. 3.
The lock core .21 preferably contains double shear line pin tumbler mechanism and permit removal of the lock core from the padlock housing and by another key to perform the usual locking and unlocking functions as described in my Patent No. 1,384,022 issued July'5, 1921.
The longer leg 12 of the padlock shackle is boredfor' the reception of a compression spring 28 by which the shackle is urged outwardly. The shackle is guided and limited in its outward movement by a guide or key pin 30 operating in a longitudinal groove 31 and an annular groove 32 in said shackle,
the longitudinal groove 31 permitting lengthwise movement of the shackle and the annular. groove 32 being near the end of the shackle leg 12 and permitting the shackle to be turned or rotated when in its outermost position. The pin 30 is inserted in a suitable transverse hole inthe plug member 17 and is held in place by the lock core 21 and by a key plug extension hereinafter described.
The shackle legs 12 and 13 are provided with notches 33'wherein two latch members 35 are adapted to engage. The inner ends 7 as shown in Fig. 1 and said lapped ends are provided with notches 37 wherein two diametrically opposite pins 38 on'the end of rotary key plug extension 40 are operatively operable by onekey to withdraw the gate 25 s disposed. The key plug extension 10 is rotatably mounted in the upper end of the medial bore and is connected with a helical torsion spring 41 that tends at all times to turn the extension 10 in the proper direction to move the latch members outwardly into the locked position.
The end of the extension adjacent the lock core 21 is provided with two arcuate grooves 42 into which project the two diametrical-y opposite pins 23 on the key stop 22 that is secured to the end of a key plug 13 in the lock core 21. The arcuate grooves 42 permit an idle movement of substantially ninety degrees of key plug pins 23 thus permitting the latch members to be retracted by turning the extension member substantially ninety degrees and then allowing the key plug 43 to be turned backward idly to the starting position so that the key may be removed therefrom, it being understood that the key of a pin tumbler lock can be removed only when the tumbler pins are properly aligned.
The lock core 21 may be unlocked and withdrawn at any time to facilitate refilling and changing the combination of the same.
The padlock is unlocked by inserting a proper key in look core 21 and turning key plug 18 through an angle of substantially ninety degrees thus withdrawing latch members 35 from notches 33 and permitting spring 28 to snap the shackle member outwardly. After the padlock is unlocked the key may be withdrawn from the lock, one latch member 35 being pressed against the longer leg 12 of the shackle by torsion spring 41 and thus holding both of said latch members 35 retracted. /Vhen the pad"- lock shackle is pressed into the closed position latch members 35 will snap into notches 33 and lock the same.
The longitudinal slot 31 in the longer shackle leg 12 makes it impossible to press the shackle down except when the shorter leg of the shackle is in alignment with the proper opening in the end of the padlock.
the foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that numerous changes in the same may be made within the scope and spirit of the following claims.
I claim: V
1. In a padlock, a relatively large inassive housing'having three intersecting lock receiving, tubular bores extending from the bottom end upwardly and having two shackle receiving bores extending from the top end downwardly, a J shaped shackle having a longer leg and a shorter leg both arranged to protrude into said shackle receiving bores, said shackle legs being notched on their inner sides, plugs partially filling said lock receiving bores, a key pin in one of said plugs for engaging with the longer leg of said shackle and limiting the movement of the same, the shackle leg being slotted for the reception of the key pin, a
pin tumbler lock core arranged to be removably secured within said lock receiving bores by key operated means, a rotatable key plug in said pin tumbler lock core, a key plug extension connected with said rotatable key plug by means affording lost motion therebet *een, a spring tending to turn said key plug extension in one direction, two latch members slidably mounted in lapped relation in the upper part of said housing and arranged to enter the notches in said shackle and means for moving said latch members by turning said key plug. I
2. In a padlock a housing having three intersecting lock receiving bores extending from the bottom end upwardly and having two shackle receiving bores extending from the top end downwardly, a shackle having a longer leg and a shorter leg both arranged to protrude into said shackle receiving bores, said longer shackle leg having a lon gitudinal groove, plugs partially filling two of said lock receiving bores, a key pin in one of said plugs for engaging within the groove in the longer shackle leg and limiting the longitudinal movement of the shackle, latch members arranged to engage with and lock said shackle and a lock for operating said latch members.
