UNITED4v STATES 'PATENT OFFICE] JAMES J.K TURNER, oF RICHMOND, INDIANA, AssIGNoR on ONE-HALF His VVVRIGHT 'IO'JQHN F. MILLER, OF SAMEy PLACE.
IMPROVEMENT IN PAnLocKs,
Specification forming` partv ofl Letters Patent No. 197,911, dated December 4, 1877; application filed October 13,1187?.
useful Improvement in Padlocks, of which thefollowing is a full, clear, and exact description. `This invention relates to a padlock such as i described in an application for Letters Patent filed by me in the United States Patent Oflice of even date with this application, the lock being so constructed that, in the act of unlocking the shackle, the key is caught in the lock, and cannot be extracted therefrom until the shackle has been again locked by the bolt or bolts.
In the lock now under consideration, I provide the key-confining tumbler with an additional hooked arm, adapted to engage the shackle from one side while the bolt engages it from the other side. I also dispense with the dogl ging-heel on the shackle, and substitute therefor a separate dog, which engages or releases the key-confining tumbler according as the free end of the shackle is in or out of the lock-case.
In the annexed drawings, Figure l is a perspective view of the lock minus the face-plate, showing the shackle unlocked and the key caught. Fig. 2 is avfront elevation, showing the position of the parts when the shackle is locked. Fig. 3 is a perspective view of the ltumbler and the "clogging-pawl seen from the rear side. Fig. 4 is a perspective view of the bolt seen from the front side.
The same letters of reference indicate idenhas an opening in the proper position for the entrance of the wedge-shaped end of the shackle.
The tongue c of the sliding bolt C is beveled so that the shackle can force the bolt back against the stress of its spring C', which throws it forward again as soon as the recess in the shackle registers with the tongue c of the bolt,
f by which-the shackle is locked from one side. ,This sliding bolt, the form of which is clearly shown fin Fig. 4, moves between suitable guides on the case. v
' The tumbler D tis pivoted on a fixed studpin, d, from which it extends beyond the keyhole,`its extreme end resting against any suitable fixed abutment of the case. Its lower edge is provided with a locking-tooth or hook, d1, in front of the shoulder of the bolt on which the key acts in retracting it, and with an elongated hook, d2, which extends along one side of the key-hole. Between these hooks the key is caught and confined inunlocking the shackle. An upwardly-projecting arm, D', of the tinnbler terminates in a hook-head, d3, adapted to enter the recess in the shackle, to aid the bolt C in securely holding it locked.
The hook-head of this arm is suitably beveled,so that the wedge-shaped end ofthe shackle can force it back on entering the case.
One end of the spring E acts on thisV armm'D' lto throw the tumbler down on its abutment, Y while the other curved 'end of said .spring is held in position to bear against the'end of the shackle, to throw it up the moment it is released from the hold of the bolt and hookheaded arm D' of the tumbler.
Adjacent to the hook-head d3 a boss, d, is formed on the rear side of the tumbler, on which the end of the dogging-pawl F bearsA when the shackle is unlocked. This doggingpawl is pivoted at f to the case, and is acted upon by a spring, F', which tends to throw its end upward. The pawl extends across the shackle-opening in the top-plate of the case, and its free end is pressed down by the shackle, on pushing it into the case, so as to release the boss "d4 on arm D', which is then at once thrown forward by spring E, to' engage.
the shackle with its hook-head.
In unlocking, the bit ofthe key is first caught behind the hook d' of the tumbler. As soon as the tumbler has been lifted the shackle is liberated from the hook-head ofthe arm D' of the tumbler, but is still retained by the sliding bolt. On retracting this bolt the shackle is expelled by spring E, and at the same moment spring F' throws the pawl F up against the hook-head, and infront of the boss d* on arm Df, thereby dogging the tumbler, so that it Whose position registers about With the posi-- tion of the key, as shown in Fig. 2-no matter Whether it is turned to the right or to the left.
rIhe projection d5, on the rear side of the extreme end of the tumbler, is adapted to dog the tail end of the bolt.
Should the recess of the shackle become clogged, so that neither the sliding bolt nor the hook-head of the tumbler can enter it, the tumbler Will be maintained in the lifted position 'by the shackle itself, though released from the dogging-paWl; and,4 if the clogging is of such a nature as to leave room for the entrance of the hook-head of the tumbler, but so as to exclude the tongue of the sliding bolt, the tail of the latter, being then under the projection d5 of the tumbler, Will still hold the latter in the lifted position. Thus the key Will not-be released until both the sliding bolt and hookhead of the tumbler have engaged the shackle.
.What I claim as my invention, and desire to secure by Letters Patent, is
1. In a padlock, the combination, substantially as specified, of the key-confinin g tumbler, the shackle and the dogging-pawl, arranged in the path of and operated upon by the free end of the shackle of said tumbler.
2. In a padlock, the combination, substantially as speciiied, of the key-confining tumbler, provided with a hook-head for engaging the shackle, the dogging-pawl, and the shackle.
3. In a padlock, the combination, substantially as specified, of the key-confining tumbler, provided with a hook-head for engaging the shackle, the dogging pawl, the sliding "bolt, and the shackle.
In testimony whereof I have signed myname to the foregoing specification in the presence of two subscribing Witnesses.
