'This invention relates to certain vnew and useful improvements in box lock.V

` The primary object of the invention is to provide a lock embodying a'hasp and a keep- 7 er and in which the keeper forms part of the lock mechanism for' the box, the keeper for the hasp being displaceable by releasing part of the lock mechanism through the action of a key to` expose another' key receiving '1U opening for the reception of the same key to release the main bolt of the lock and Vpermit opening movement of the box cover.

' 'With the above and other objects in view that will become apparent as the nature oi 15 the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

Figure 11 is a sioned latch and Figure 12 is a side elevational view of the key employed V:tor releasing the lock mechamsm.

Referring more in detail to the accompanying drawings, there is illustrated a lock box perspective viewoi the tenplate for the shackle keeper;

having a front wall 1, a bottom wall, end k walls, a rear wallrand a cover2 hinged to the rear wall as at 3 and carrying corner blocks 4t correctly to locate the cover on the box body when in closed position; The free edge of the hinged cover 2 carries a swinging hasp 5 received on a keeper 6 that is in the form of a U-shaped shackle associated with the front wall 1 of the box and with which a padlock 7 or otherretaining means may be associated, the main lock for the box, however, being located interiorly thereof.

The lock mechanism within the box is mounted upon a plate 8 secured to the inner side or the front wall 1 of the box adjacent its upper edge, the plate having right angularly directed

walls

10 and 11, the plate 11 intermediate its upper and lower edges carrying an angularly directed arm 12 parallel with the plate 8` The shackle keeper 6 comprises a long leg 13 and a short leg 14, the long leg 13 of the keeper shackle extending through registering openings in the front wall 1 of the box and the plate 8 and through an opening in the arm 12 while the short leg,r 14 of the keeper shackle extends through openings in the front wall of the plate and projects into a barrel 15 as shown in Figure l0 carried by the inner sides of the plate 8. A coil spring 16V surrounds the long leg of the keeper shackle between the plate 8 and nl o abutment 17 on said leg, for normally iniuencing the keeper shackle in a direction inwardly of the box.

The keeper shackle is normally locked within the box by means of a tensioned latch 18 slidably mounted between guides 19 on the plate 8, 'a linger 2O of the latch 18 being engaged in a side notch 21 formed in the short leglt of the keeper shackle. One end of the latch 18 carries an angle flange 22 having an opening 23 therein to receive one end of a coil spring 24, the other end of the coil spring being attached to the angle Wall 10 on the plate 8 for normally iniiuencing the latch 18 in a direction toward the short leg of the keeper shackle. `The end of the latch 18 opposite the angle end 22 is provided with a lateral flange 25 having upstanding abutments 26.

The key for operating the lock mechanism is shown in Figure 12 and comprising a sha nk 27 having an angle Ward 28 at one end, a collar 29 intermediate its ends to limit projecting movement of the key into the lock and a handle 30 upon its other end. To release the finger 20 of the latch 18 from the notch in the side of the short leg of the keeper shackle, the key 27 is inserted through the opening 31 in the front Wall of the box to be positioned between the abutment 26, it being understood that the side of the barrel 15 is slotted as at 15a to accommodate the passage thereinto of the linger 2O for engagement With the shackle leg. The key 27 is then turned to engage the abutment 26 adjacent the latch 18 and to shift the latch against the tension of the spring 16 and at which time, a pull upon the latch keeper 6 Will move the short leg 14 thereof outwardlyof the box and expose a key receiving opening 32. Return sliding movement of the latch 18 under influence of the spring 24 is limited by the end abutment 26 enga ging the angle end wall 11 of the plate 8 for also limiting projecting movement of the latch finger 20 into the barrel 15.

The locking bolt for the hinged cover 2 is in the form of a U-shaped rod comprising a bolt 33 and a guide rod 341 connected at adjacent ends by the cross rod 35, the bolt 33 and rod 311 being slidable through openings in the

angle walls

10 and 11 of the plate 8 with the cross rod 3'5 positioned outwardly of the Wall 1(). 'lhe end of the bolt 33 projecting through the end Wall 1-1 is adapted for engagement Vith a keeper` 36 depending from the hinged cover 2. The bolt frame is normally tensioned in a direction of movement for latching engagement with the keeper 3G by the coil 'spring 37 having one end extended through the end Wall 10 of the plate 8 and engaged 'with the cross rod 35 of the bolt fram?, as shown at 38, While the other end of the f paring is er raged with the linger 39 projecting outwardly from the plate 8 as shown in several of the figures.

lVith the latch finger 2O disengaged from the side notch in the short leg lll of the keep er shackle G and said short leg removed from the box and displaced laterally of the key receiving opening 32, the key shown in Figure 12 is then inserted in the opening 32 for passage through the barrel 15, the side of the barrel being slotted as at 4() to accommodate the passage of the key ward 28 as shown in Figure 7. The Ward 28 of the key is then located in engagement With the lug 41 projecting laterally from the guide rod 34 and upon rotation of the key 27, the guide rod, together with the bolt 33 are shifted against the tension of the spring 37 to disengage the bolt 33 from the keeper 36 as shown in Figure 7 and at which time the cover 2 of the box may be opened upon its hinged mounting. Movement of the bolt frame against the tension of the spring 37 is controlled by the stop 42 upon the end of the guide rod 34 that moves into engagement with the end Wall of the plate 8.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that the padlock 7 engaged with the keeper shackle 6 as shown in Figure 1 is foreign to the particular lock mechanism forming the basis of this application, except that the hasp 5 overlies the key receiving opening 31 WhichV permits operation of the sliding latch 18. It is necessary to release the sliding latch from engagement With the short leg of the keeper shackle in order topermit the short leg to be removed from the key receiving opening 32 and throuoh which opening the key for operating t e bolt 33 is passed, and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
