IVIICHAL ZUKOWSKI, OF WILMINGTON, DELAWARE.
PADLOCK.
Specification of Letters Patent.
Patented May 25, 1920.
Application filed January 27, 1920. Serial No. 354,429.
To all whom it may concern:
Be it known that I, MIcniAL ZUKOWSKI, a citizen of Poland, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.
The primary object oi? the present invention is to provide a pad lock of the type embodying a tensioned sliding bolt adapted for engagement with the latch end of a swinging shackle, the bolt carrying a screw adapted to be engaged by a threaded key for shifting the bolt against the tension thereon to release the swinging shackle.
With the above general objects in view and others that will become apparent as the nature of the invention is better understood, thesame consists in the novel combination and arrangement of parts hereinafter fully described in connection with the accompanying drawing.
In the drawings wherein like reference characters designate corresponding parts throughout the several views,
Figure 1 is a longitudinal sectional view of a pad lock constructed in accordance with the present invention with the key inserted in thedock casing engaged with the bolt screw to retract the bolt,
Fig. 2 is a cross sectional view taken on line lL-II of Fig. 1 showing the shape of the bolt head with the cross pin preventing rotary movement thereon,
Fig. 3 is a cross sectional view taken on line III-III of Fig. 1, and
Fig. 4c is a rear end elevational view of the pad lock.
Briefly described, the present invention aims to provide a pad lock embodyinga casing having a swinging shackle pivoted thereto with the latch end of the shackle adapted to be projected into the casing, for automatic locking engagement with a tensioned bolt slidable therein. A transverse pin carried by the casing cooperates with the bolt head to prevent rotary movement or the bolt head within the casing while a spring normally holds the bolt head forwardly projected into locking engagement with the shackle latch. A screw is carried by the sliding bolt and is adapted to be engaged by a tubular screw key for shifting said bolt against the tension of the spring to release the shackle.
Referring more in detail to the accomthe casing o panying drawing, there is illustrated a pad lock comprising a cylindrical casing 5 closed at one end as at 6 with a removable end wall 7 at its opposite end. As shown more clearly in Figs. 1 and 3 a strap 8 surrounds adjacent the end wall '7 and carries extensionears 9 between which the shackle 10 is pivoted upon the pin 11. The shackle 10 as shown in Fig. 1 embodies an intermediate looped portion 12 and a latch head 13 adapted to be projected through the opening 14: in the casing 5 adjacent the end wall 6.
A sliding bolt 15 is mounted within the casing 5 and includes lower and upper pro jections 16 and 17 respectively, inclosing a transverse pin 18 in engagement with the lower flat face of the upper bolt projection 17 as shown in Fig. 2, the upper face of said projection being curved for contact with the inner wall of the casing 5 for slid ing engagement therewith while the pin 18 prevents rotary movement of the'bolt 15 within the casing.
A coil spring 19 extends between the end wall 7 of the casing 5 in the bolt 15 to hold the bolt normally forwardly projected in the position illustrated in Fig. 1 for locked engagement with the latch 13 of the shackle 10, thelocking engagement between the bolt projection 17 and latch 13 being automatic by the latch 13 riding over the beveled face 17 of the bolt 15.
In order to efiect a release of the shackle 10 from the casing 5, there is provided a screw extension 20 carried by the bolt 15 and inclosed by the coil spring 19, the threaded bolt 20 being engaged by the tubular key screw 21 insertible through the end wall opening 7 with the flange 22 carried by the key screw 21 engaging the end wall 7 of the lock casing duringthe rotation of the key. When the key is rotated, the screw 20 being non-rotatably carried by the shiftable bolt 15, is received in the tubular key screw 21 against the tension of the spring 19 to free the bolt extension 17 from the shackle latch 13, thus to permit the swinging movement of the shackle 10 upon its bearing ll'for releasing the shackle from the casing. An eye 5 is carried by the casing 5 at the opposite side of the shackle 10 and carries a chain 23 that is receivable in the looped portion 12 of the shackle for retaining. objects of different characters.
While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made in the details thereof without departing from the spirit and scope of the invention as claimed.
What I claim as new is V A pad lock of the type described comprising a tubular casing, a bolt slidable therein,
' 7 upper and lower inwardly directed extensions carriedby the bolt, the extensions having parallel opposed faces and outer faces'curved concentric with the casing to hold the bolt transversely positioned in said casing,ia pin carried by the casing and engaging the lower parallel face of the upper 1 extension to prevent rotary movement of the bolt within said casing, a shackle pivoted to said casing, a head carried by said shackle adapted for engagement with the upper ex- MIOHAL ZUKOWSKI.
