Fi ure 8 is a rear elevation of the lock caszo ing showing the two springs in position.

While my lock is designed, primarily for cedar and other chests, at the same time it will be understood that its use is not thusrestricted. 4

Cedar chests are designed to provide a tightly closed receptacle in which to store clothing, etc., but this object is frequently defeated by the failure of users to see that tops are tightly closed and locked in that position which can be done if the lock is operated by the key, but this is almost habitually forgotten.

It is the purpose of my invention to provide a combined latch and lock for such chests so that in the mere act of closing the lid of the chest it is automatically latched in such closed position; and to further provide means whereby the keeper may be released without the use of a key;.and to further provide a-key lock whereby the chest may be securely locked by a key; and with these and other objects my invention consists of the parts and combination of parts hereinafter set forth.

The reference number 9 designates a chest of any approved construction provided with a lid or closure 10, said lid being provided with a catch 11.

edge with a ange 13 being provided with an The lock Iplate 12 is provided at its top opening 141 through which the latch 11 may project when the lid is in closed position.

A lock casing wall or flange 15 is secured on one face of'the lock plate 12 and is provided with suitable notches or recesses 16 in which the trunnions 17 of the rocking keeper plate 18 are mounted within the wall 15, said keeper having rigidly mounted thereon the key pin 19, said keeper being provided with a keeper opening 20 into which the latch 11 projects, as shown in dotted lines in Figure 5. To maintain the keeper 18 in the normal position shown in Figure 5 I provide a spring 20, one end of which is secured to the lock plate 12.

A look bolt 21 is slidably mounted in notches formed in the casing wall 15 and is so mounted that it may be moved bodily transversely of the casing wall 15 within certain limits and is held in assembled position, as is the keeper 18 by means of the back 22 of the lock which in turn is securely fastened against accidental displacement to the casing wall 15 bysuch as rivets 23, said back being provided with a key hole 24.

This bolt 21 is provided with an arm 25 slidably mounted in one of the notches 16 of the wall 15, the end of the bolt being provided with a comparatively wide upwardly extending flange 26, which, when the bolt is moved to the dotted position shown in Figure 3 bridges the joint between the keeper 18 and the casing wall thereby locking the keeper against movement, whereas in its full line position in Figure 3 it leaves the keeper 18 free to rock. Notches 27, 28, are provided in the under edge of the locking bolt 21 separated b a lu 29 whereby'when the bolt 21 is move to t e right the, notch, or recess 28 engagesa stop 30, and is held in that position by the spring 31 which exerts a downward force on' the bolt 21, one end of the spring 31 being secured to the plate 12.

In its under face the locking bolt 21 is provided with a cam like face 32, against which the key, when mounted on the pin 19 is moved to throw the lock bolt 21 into locked, or unlocked position.

It will be noted that one of the outstanding features of my lock is the double function of the pin 19, viz: itfunctions as a standard key pin and as a push button to release the latch.

To latch the lid in closed position it is only necessary to close it, whereupon the latch 11 will engage the opening 20 in the keeper 18 as shown in Figure 5. Now when it is desired to again open the lid, it is only necessary to utilize the key pin 19 as a push button to throw the keeper 18 to the position shown in Figure 6 whereupon latch is free and the lid may be raised. In the event that it is desired to lock the lid it is only necessary to mount the key on pin 19 and move the bolt 21 to the left to the dotted position shown in Figure 3.

I am aware that changes may be made in the detailsof construction herein disclosed without departing from the scope of the appended claims.

What I claim is:

1. In a lock, the combination with a swingingly mounted keeper, a combined key pin and push button secured to said keeper, and

5 a locking bolt adapted to be moved relatively to the keeper to lock the keeper against movement.

2. In a lock, the combination with a casing, of a keeper rockingly mounted in said casing,

a combined key pin and push button mounted on said keeper, means to hold the keeper normally in operative position, and a looking bolt to hold the keeper against movement.

3. In a lock, a casing, a keeper rockingly mounted in the casing, a combined key pin and push button mounted on said keeper, means to hold the keeper in operative position, a key operated locking bolt adapted to be moved relativel to the casing and keeper to free the keeper or or look it against movement.

4. In combination, in a look, a casing, a floating keeper movably mounted and eonfined in its movements Within said casing,

means to yieldably hold the keeper in locking position, and means extending externally of the casing to temporarily move the keeper tounlocked position.

5. In combination, in a look, a casing, a keeper. movably mounted and confined in its movements within said casing, means to yieldably hold the keeper in looking position, and means mounted on the keeper and extending externally of the casing to temporarily move the keeper to unlocked position.

In testimony whereof I afiix my signature.

JOHN R. HOGAN.
