To all whgm 'it may con/:em:

Be it known that I, PASQUALE DANGnLo, a subject of the King of Italy, residing at Newark, in the county 'of Essex and State of New Jersey, have invented certain new and useful Improvementsin Padlocks, and I do hereby declare the following to be a full, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to -igures of reference marked thereon, which form a part of this specification.

This invention relates to a lock that is particularly designed for a pad-lock, but is adapted for other uses, the lock being of the class that has a shackle arranged to slide into a casing to be locked therein, and to slide from the casing and then'be swung to have one end clear the casing. The present lock is designed to snap shut, when the shackle is slid into the casing, but provides a means for locking the shackle by means of a key besides the automatic means, the key locked portion of the device preventing the unlocking by 'means of the springactuated locking means, so that the key locked portion must be unlocked rst.

The .device provides'a means for allowing longitudinal action of a key used in conjunction with the lock,

so that the key canoperate in different planes, in a` par-` ticular sequence, to provide for the unlocking of different elements in their turn to complte the unlocking of the device. i

The invention is illustrated in the accompanying drawing', in which i Figure l is a face view of the lock with one side thereof removed, with the lock after it is shut, show.-

A completely locked. Fig. 3 is across-section on line 3, 3, in Fig. 2, and Fig. 4 is a horizontal section on line 4, in Fig. l.

The device embodies a casing l0, in the top 11 of which, and in the bracket l2, is pivotally arranged the end 13 of a shackle 14. The shackle can be slid from the casing, as shown in Fig. 1 in dotted outline, and is then free to be swung around, it being rotatably'arranged in the casing. The shackle has a normal tendency to emerge from the casing through the action of a spring I5 bearing on a pin 16, in the portion I3 of the shackle. The other end of the spring 15 bears on the casing.

To normally hold the shackle shut,'or in its locked position, is a lever I7 pivoted at I8, and having a nose 19 to enter a slot 20 in thepportion 13, the nose on the lever being -orced over by the action of a spring 2l bearing on a stud 22. The end 23 of the lever 17 projects downward in close proximity to-a pin 24 for-the reception of a key, the relation being more specically 'brought out hereafter.

When the shackle has been slid into the casing, as in Fig. l, it is locked by the action of the spring 21 forcing the nose 19 into the slot 20. However, the lock can be securely locked by a key manipulation of some of the parts, this being done by a key 25, shown in dotted outline in Figs. 2 and 3. This key bears on a block 26 which is slid over by the action of the key, and has the stud 27 enter a perforation 28 in the 'end 29 of the shackle 14, the block being guided by the pin 27 passing through the bearing plate 28a and also by the rod 29 sliding in the fprked support 30. This forcing of the block is done against the action oi a spring 3l which bears against the block, being held against displacement by a pin 32, and the block having a flat plate 33 attached thereto which has a notch 34. When the block has passed over to the point shown in Fig. 2, and where the key 25 will now just clear it, the block is locked by i the finger 35 arranged to slide in suitable bearings, and being actuated by the spring 36 to force it up into the notch 34. The finger 35 has a lug 37 thereon. The key 25, after the lock is locked? can be swung around without any hindrance when normally operated. This is Idue to the fact that the key has cleared the bottom of i the block 2G, and the lug 37 and the end. 23 of the lever I7 are out of th'e plane of rotation of the key. The key revolves on a key-pin 24 which is narrowed down on its inner portion' to form a shoulder or a stop piece for the washer 38,V which is held tight by the action of a spring 39. To release the lock, the kein-operated locked portion must be unlocked by means oi the key, and the key 25 is forced in against the action of the spring 39 until it is within the plane of the lug 37, which will be apparent from Figs. 3 and 4. When the key is pushed in the required distance, it follows the path as indicated at a in Fig. 2, and when the lug 37 is drced downward by the key, it causes the pin 35 to release the plate 33 of the block 26, and the spring 3l operates to throw the block 26 to cause the pin 27 to be withdrawn from the end 29 of the shackle 14. The parts then assume the position showgirl Fig. l, and the key cannot be thrown back in `the reversed direction on account of the lower end of the block 26 being in its path o travel.' The key is thus continued in the direction of the arrowva, and when the key is twisted aroundto be on the leit side, as we look at the drawing, of the end A23 of the lever 17, it is forced in against the action or' the spring 39 much further than it was necessary to force it for the operation enters the casing. A guard 40 can be placed inside the casing adjacent to washer 38 so that the key, when it vey theoimpression that it cannot be further forced into the casing. The cfuard lllis arranged to partly snr-- round the pin 24, and it causes the rotation of the key 25 in but one planefor a part of its rotation. The spring 39 is stiffso that any accidental longitudinal movement o the key is avoided, and there is no suggestion of a yielding pressure to an ordinary user ot` the key.

It will be seen, from this description, that the key operates in three planes, first to lock the key-operated portion of the device by engaging the block 26, and must then beforced in first along its pin to engage the lug 27, and must he released to clear the guard 40 and then forcing in still further to engage the end 23 of' the lever to unlock the spring actuated locking portion.
