Specification of LettersrPatent. f Patented Aug. '7, 1917. i

Application led April 2, 1917. Serial No. 159,360.

To all whom t may concern.'

Be it known that I, FRANK M. Dnvn- REAUX, a citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates topadlocks and has particular reference to the class of padlocks in which a sliding key rather than a rotary key is employed as an unlocking means.

The primary object of the invention is to provide, in a padlock, a locking means of such a character as will not permit the use of any instrument, other than one which has been designed in accordance with the interior mechanism of the padlock, to facilitate the unlocking of thelocking means.

Another object of the invention is to provide, in a padlock, a means whereby the shackle of the padlock, after having been unlocked, will be caused to assume an open position with respect to the padlock proper, and to retain such a position until it has become desirous to replace the shackle again into a closed position. y

With the above and other objects in view, the invention will be more fully described in the following description, taken in conjunction with the accompanying drawings, and the particular features of novelty will be pointed out in the appended claims.

In the drawings, in which similar characters of reference denote similar parts in the views,

Figure 1 is a face view of the lock with its cap removed, showing the locking elements in a locked position,

Fig. 2 is a cross section of Fig. 1, taken on the line :I0-, showing it from the. end which receives a key,

Fig. 3 is a face view of a key,

Fig. 4 is a top plan view of the tumbler disks and the tumbler segments, taken on the line -m of Fig. 1 and showing a portion of the case in section,

Fig. 5 is a face view of a tumbler segment, and

Fig. 6 is a face view of a tumbler disk.

Now referring more particularly to the drawings, A indicates a case 'comprising a wall 10, a flange 11, and a cap 12. The flange 11 is formed integral with the wall 10 at its outermost edge and is adapted to receive upon its face 13 the cap 12 which serves as a closure for the casel A.

A shackle 14 is pivoted within the case A at a point relatively near the inner wall 15 of the flange 13, and is provided at its pivoted end with an elongated member 16 which carries a lug 17.. The shackle 14 is provided at its movable end with a notchv 17 which is adapted to receive a hook 18, carried by an end 19 of a pivoted lever v20. The hook 1 8 carried by the end 19 of the lever 20, is held normally within the notch 17, as is shown in Fig. 1, by means of a flat spring 21, having one end secured to the hub 22 of the lever 2O and its other end engaging a pin 23 which passes through the wall 10 and the cap 12 of the case A.

An elongated rib 24 is disposed, within the case A, upon the wall 10 and is provided j :and the cap 12'of the case A on which vis revolubly mounted a plurality of 'tumbler disks 33. The tumbler disks 33 are each provided with a stop 34 and a plurality of teeth 35. A plurality of tumbler segments 36y are disposed between 'the tumbler disks 33 and are fastened therebetween by means of pins 37 passed through each of the tumbler disks 33 and each of the tumbler segments 36. The tumbler segments are each provided with a lug 38 and a stop 39. In order to hold the tumbler segments 38 and the ltumbler disks 33 in a normal position, as is shown in Fig. 1, there is provided a spring 40 which is coiled around the pin 32, having one end 41 adapted to slidably engage one end of the tumbler segments 38 and the other end 43 adapted to engage a stop pin 44 projecting through 'the wall 10 into the case A.

When it is desired to unlock the locking elements within the case A, the key 27 is inserted into the key way 45, whereupon the end 46 of the key 27 comes into contact with the stops 34 of the tumbler disks 33 and the stops 39 of the tumbler segments 36. Upon moving the key farther into the key way 45, the teeth adjacent to the stops 34 of the tumbler disks 33 move into the notches 47 of the key 27. When the key 27 has completed its inward course, thelugs 38 of the tumbler segments 36 will have entered successively the apertures 4S, 49 and 50 and the teeth 35, which are the farthest distance from the stops 34, of the tumbler disks 33 will be positioned in the notches 51 of the key 27. l/Vhen the tumbler disks 33, together with the 'tumbler segments 36 have been rotated as above described, the tumbler segments 36 will have come into contact with the end 52 of the pivoted lever 2O and will have moved it sufficiently about its axis 53 to permit the hook 18 of the lever 2O to become disengaged from .within the notch 17. Upon the releasing of the hook from the notch 17 the shackle 14 will assume an open position with respect to the lock proper due to the influence of the spring 30 acting upon the elongated member 16. Upon relieving the pressure from the key 27, necessary to hold it within the case A, the tumbler disks 33, together with the tumbler segments 36, revolve about the vpin 32 until the teeth 35 of the tumbler disks 33 which are farthest distance from the stops 34: of the tumbler disks 33, come into contact with the stop pin 44, and the pivoted lever 20 acting under the influence of the spring 21, will assume a position such as will permit the hook 18 to snap into a locked 'position when the shackle lt has been moved to the position as shown in Fig. 1.

I claim:

1. A padlock comprising a case, a shackle having one end pivoted within the said case, a pivoted lever carried between the walls of the case, and provided at one end with a hook adapted to'engage within a notch carsaid pin having one end adapted to engage -1 an end of the said tumbler segments and the other other end engaging a stop pin passed through the wall of the said case.

3. The combination with a padlock, comprising a case, a shackle, a pivoted lever carried between the wall and the cap of the case, tumbler disks rotatably mounted on a pin passed through the wall and the cap of the case, teeth carried on the periphery of each of the said tumbler disks, a stop carried by each of the said tumbler disks, a plurality of tumbler segments disposed between the said tumbler disks, and lug carried by each of the said tumbler segments, of a key provided with notches adapted to receive the teeth of the said tumbler disks and with apertures adapted to receive the lugs carried by the said tumbler segments.
