LocK.

Application led October 15, 1909. Serial No. 522,890.

To all whom 'it may concern:

Beit known that I, 'FRANK SoLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Locks, of which the following is a specification. n

My invention relates to certain improvements in combination locks.

The object of my invention is to provide such a'lock with a detachable key, which must be inserted in the lock in a particular manner in order to actuate both the clic and the lock mechanisms.

The invention vis particularly adapted for use in places where it is not desirable to have a permanent knob on the combination Flock,and the lock must be made at a reasonable price.

In the accompanying drawing :;-Figure 1, is a face view of the lock with one side of the casing removed; Fig. 2, is asectional view on the line 2-2, Fig. l; Fig. El,v is a Sectional view on the line 3&8, Fig. l; Fig. 4, is a sectional view on the line 1 -4, Fig. 1`; Fig. 5, is a perspective 1' view illustrating parts of the lock detached; and Fig. 6, is a perspective view of one form of key which may be used.

A is the back casing of the lock, B is the front casing ianged at b, b and notched at b to receive the projections a, a of the back casing A. 'A screw b2 passes through an opening in the casing B and into a post C projecting from the back casing A.

I) ,is the locking mechanism, consisting.l of

a Series of tumblers and washers d, d', ay

vlocking bolt E having an extension e slotted at e to engage the post C, a bolt thrower F having a nose j engaging the projections e2 and c3 on the bolt E and pivoted to this bolt thrower is a lever G having a spring g and a projection g adapted to engage the. notches in the tumblers.

Heretofore the driving disk was mounted on the stem of a permanent knob, but in the present instance the driving disk I is carried by a hollow stud I adapted to an opening in the hollow post A projecting from the back A of the casing; the tumblers and washers being held in place by a split ring d2 adapted to a groove in the post, as illustrated clearly in Fig. 2. The hollow stud has in its end opposite the end carrying the drivin disk, a slot z' clearly shown in Fig. 1, an

` B. l.shaped to correspond tothe portion a of thev .key-.N so' that when the key visturned the casing B to theV casing B. The-end of the casing B is pressed in, as shown at 7c, to

f form ratchet teeth on the inside of the. casing. Within the casing B is a click disk M having a. Series of depressions m, twelve in the present instance, which aline with the projections on the inner surface of the easing B" to form a click mechanism. A spring m2 is arranged back of the disk so as to force 'it in contact with the end of the casing A hole mvin the center ofy the disk is click-disk willturn with it.l /The key'can be forced through the opening in the casing B', so that the portion n of the key will bear against the click disk, and by j pressing against this click disk with the. key more or less sound can be made, so that in the place of -Iigures or letters on the casing, and a pointer, as in the ordinary combination lock, the clicks are counted, and if any one is close to the person operating the lock, and it is desired that the combination should not be read, by placing a slight pressure on the key, the click disk is pushed away suiciently fromthe projections on the casing that there will be no sound, but the click will be felt by the hand'of the operator, and

'in some cases, where the operator is familiar with the combination, the click disk may be pushed entirely clear of the projections on the casing and the lock turned to the right and left at the proper combination.

' In order to engage the lock mechanism by the key, theI key must be moved into its eX- treme position so that the end n will'engage the slotted portion i of the stud I', and, 1n thepresent instance, as this slot is oi-center, the key must correspond with it, and consequently the key must be placed inthe lock in a certain position in order to not only pass through the click disk M but nation, but also through the I and into positioirin the .f The sha v the slot and the opening in the click isk will depend upon the shape of the ke and the key can be sha ed 1n many di erent wa s, so that a n um er of changes can be ma e, not only in the combiin theshape of the key and the slots.

v making theveasing, in two lparts, one' part A having' the projections a,l a andgthe' part B having the notches, theparts. can be readily snapped together and,'1 f necessary,

the screw b2 fastening.

I claim fmaybe used as lan additional i 1. The combination in a lock, of a casing,

a combinationmechanism within the casing, a driving disk f'or actuating the combination mechanism, said drivlng disk having an opening, a removable key shaped to fit said 'if both the click mechanism with a detac ab 'e key adapted toengage 4 operin and click mechanism also engaged by the 'ey so that, on the turningl of the key, o and the driving disk will be operated. j v

2. The combination in a lock, of acasing, aseries of tumblers and washersmounted therein and'forming the combination mechanism, a bolt, actuating mechanism therefor,

a driving disk mounted'intlie casin independent of the tumblers but connecte thereto, said driving disk having a hollow spindle -with an 4irregular opening therein, and 'a click mechanism eonsistin of -a notched casing and a notched disk, e projections' on the disk enga in the notches 1n the casing,`

of the click mec anism. A 3. The combination in a casing,- o a. bolt,

a series of 'tumblers and'washers mountedv on a hollow Vs indle 'projectin from the back casing of t e lock, means ir actuating the bolt when the tumblers are in a certain osition, a drivin disk, having a spindle a apted to the ho ow spindle carrying; the tumblers and having recesses to receive a pin of the-.combination mechanism, the hole 1n the combination" mechanism within the casing, a

driving disk for actuating the combinatlon, said driving disk having a hollow stud, said stud bein slotted at its extreme inner end,

with a click disk mounted within the casing, and a key adapted to an opening in the c11ck disk and shaped to engage the slotted portion of the hub of the operating disk.

In testimony whereof, I have signed my name to'this specification, inthe presence of two subscribing witnesses. V v 1 FRANK SOLEY. Witnesses:
