PADLOCK.
To all whom it may concern.e
Be it known that I, FRANK SOLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Padlocks, of which the following is a specification.
My invention relates to a padlock for use in cases where, after the lock has once been opened by the use of the key, it is desirable to prevent the removal of the key until the lock has been again closed and fastened, my invention consisting of a certain combination of parts whereby this result is attained.
In the accompanying drawing-Figure 1 is a view of the lock with the cover-plate removed and the parts shown in the locked position; Fig. 2 is a similar view showing the parts as adjusted by the key to effect release of the shackle of the lock and prevent rearward movement of the key; Fig. 3 is a similar view showing the parts in the position assumed by them after the key has been turned so as to release and permit projection of the shackle-engaging spring-bolt of the lock; Fig. 4 is a view showing the relation of the parts when an attempt is made to release the key by pushing back the spring bolt and tumbler without inserting the shackle, and Figs. 5, 6 and 7 are perspective views of the different elements of the lock mechanism.
In the drawing, 1 represents the shell of the lock and 2 one of the side plates of the same, preferably formed integral with said shell, the other side plate being detachable, but otherwise similar to the side plate 2. The pivoted shackle 3 has a nose 4 for entering the interior of the lock casing, said nose having therein an opening for the reception of the forward end of the bolt 5. This bolt is guided transversely in the lock casing and is normally projected by a spring 6 acting through the mediumof a lever 7, the latter having, at its upper end, a lug 9 bearing upon the rear end of the bolt 5, and, at its lower end, a lug 10 for a purpose hereinafter described.
In front of the bolt 5 is a tumbler 11 which is pivotally mounted upon a stud 12 in the lock and has a slot 13 for the reception of said stud, whereby the tumbler can have both a swinging movement and a sliding movement back and forth across the face of the bolt 5. The tumbler has a depending hooked end 14, and is normally retained in Specification of Letters Patent.
Application filed June 9, 1909.

Serial No. 501,071.
its forward position by means of a spring 15. Projecting from the face of the spring bolt 5 is a stump 16 which coperates with a slot 17 in the tumbler, as hereinafter described, said slot being enlarged at its forward end so as to form shoulders 19 and 25. When the lock is closed the stump 16 is in engagement with the shoulder 19 of the tumbler 11, as shown in Fig. 1, consequently the spring bolt` cannot be retracted in order to release the shackle.
The key 20 engages a keypost 21 in the lock casing, and, when turned clockwise, the bit 22 of the key first engages the under side of the tumbler 11 and lifts the same so as to raise its shoulder 19 out of engagement with the stump 16 on the bolt 5. Further movement of the key then causes the bit of the same to engage with a depending finger 23 on said bolt 5 and move the latter rearwardly so as to free it from engagement with the nose of the shackle and permit of gie opening of said shackle, as shown in As soon as the tumbler 11 has been raised by the key bit so as to carry its shoulder 19 out of engagement with the stump 16 on they bolt 5, said tumbler is moved forward by its spring 15 and a shoulder 24 on the underside of the tumbler comes into position to prevent any backward movement of the bit of the key, as shown in Fig. 2, consequently when the shackle 3 is released by the retraction of the bolt 5, the key cannot be withdrawn by turning it backwardly into line with the key hole. Further forward movement of the key carries its bit 22 out of engagement with the depending finger 23 on the bolt 5 and the latter then springs forward into locking position, the key bit 22 finally` coming into contact with the depending hooked end 14 of the tumbler 11, as shown in Fig. 3, so as to arrest the further forward movement of the key. Descent of the rear end of the tumbler 11 is prevented by reason of the fact that the stump 16 of the bolt 5 occupies the contracted rear portion of the slot 17 in the tumbler 11 and engages with the upper wall of said slot, as shown in Fig. 3.
If any attempt is made to release the key by pushing back the bolt 5 and tumbler 11 as by means of a nail, spike, or like implement m as shown in Fig. 4, such movement 4of the tumbler will carry its hook 14 out of engagement with the key bit 22 but the rearward movement of the bolt 5 will move the lever 7, so as to bring its lug 10 into the path of the said key bit 22 and will thereby retain the key within the lock casing. (See Fig. 4.)
lVhen the nose of the shackle is inserted both the bolt 5 and the tumbler 11 -will be pushed back and when said nose of the shackle is fully inserted the bolt 5 will spring forwardly, thereby permitting such movement of the lever 7 as to carry its lug 10 out of the path of the key bit 22 and at the same time the rear end of the tumbler 11 will drop so as to engage the shoulder 19 with the stump 1G on the bolt 5 and thereby lock the latter in the projected position, the key being now free to be turned (as indicated by dotted lines in Fig. 1) until its bit 22 is in line with the key hole so that it can be withdrawn from the lock casing. If an improperly bitted key is used the excessive lift of the tumbler 11 will, if the bit is too long, bring the shoulder 25 on the under wall of the slot 17 into position to engage with the stump 16 on the bolt 5, and will thus prevent the retraction of said bolt, engagement of the shoulder 24 on the tumbler with the key bit preventing the latter from being turned backward into line with the key hole and consequently preventing withdrawal of the key from the lock. If the bit is too short, the tumbler will not be lifted sufiiciently to clear t-he shoulder 19 from engagement with the stump 16, but a supplementary shoulder 2G on the underside of the tumbler will engage the bit of the key and prevent backward movement of the latter or Withdrawal of the same from the lock. Any attempt to tamper with the lock by the use of an improperly bitted key will thus be readily detected.
