This invention related to new and useful improvements in a safety lock box.

The invention has for an object the construction of an article as mentioned which is characterized by a box having spaced openings at one side for lugs from a support to support the box, and also having a cover, and a locking mechanism for holding the cover closed and operable also for the purpose of coaction with said lugs to hold the box upon the support.

More particularly, boxes of the type described in the previous paragraph would be well adapted to be used for the delivery of food outside of ones home. The arrangement allows goods such as bottles of milk or other goods to be placed within the box and locked so that only the rightful owners may remove the merchandise. A feature of the construction resides in the fact that one lock, with a key, is used for the purpose of unlocking the cover from the box and when desired unlocking the box from its support.

Still further it is particularly proposed to arrange the lock with a bolt which is pivotally mounted for unlocking the lock and is adapted to pivot in either direction solely to unlock the lock, and when pivoted in the one direction to unlock the lock and furthermore cause the releasing of mechanism adapted to coact with said lugs for holding the box in place upon said supports.

Still further the invention also proposes the provision of a novel support for attachment upon the wall of a house or other place, and provided with the lugs for the purpose of engaging into the side of the box to support the box.

Still further the invention proposes the construction of a device as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:-

Fig. 11 is a perspective view of a support frame 0 for the safety lock box.

The safety lock box according to this invention comprises a box consisting of an upper hollow frame 10 and a lower mesh construction portion 11. sists of vertical rods attached upon the frame and supporting a bottom frame 12 which is provided with horizontal rods 13. The upper edge of the top frame 10 is flat and is adapted to receive a cover which comprises a frame 14 for resting upon the frame 10, and a hollow construction including a front wall 15, a top wall 16 and mesh sides 17. The frame 10 of the box is formed with spaced openings 18 for receiving lugs from some support so that the box may be attached upon the sides of the wall or a support. A support as just mentioned is illustrated in Fig. 11 and will hereinafter be described in detail.

A lock mechanism is provided for holding the cover closed and comprises a detent 20 mounted upon the cover and adapted to engage a bolt 21 mounted upon the box. This bolt 21 is pivotally mounted as hereinafter described for unlocking the bolt when pivoted in either direction. The detent 20 comprises a head portion 20 which is mounted upon a flexible leaf 22 fixed upon a plunger 23 slidably mounted in a bracket 24 attached upon the front wall 15 of the cover. A casing 25 encloses the latch mechanism which is mounted upon the cover. A spring 25 is arranged upon the plunger 23 and acts between the bracket 24 and the plunger 23 for normally urging the plunger into a raised position. A handle 27 is located outside of the wall 15 for the purpose of 4 This lower mesh construction portion conmoving the plunger 23 downwards to engage the detent with the bolt. This handle 2'7 extends through a slot 28 in the wall. A large flange 29 is connected with the handle 27 and closes the slot in all positions of the handle. The inner end 27 of the handle directly connects with the plunger 23. The arrangement is such that the handle 27 may be depressed to lower the detent 20.

The bolt 21 is secured by several screws 30 upon the barrel 31 of the look. This barrel 31 works in a casing 32 which is formed with threads on its outer side. adapted to be disposed upon the outer side of the wall of the frame 10. A pair of diametrically opposite lugs 34 project from the flange 33 and engage with cutouts 35 upon the front wall ofthe frame for the purpose of preventing the casing from rotating. The front of the flange 33 is provided with a key opening 36 into which a key 3'7 may be inserted. This key is adapted to release the barrel 31 so that it maybe rotated. The details of this construction will not be given here since this constitutes a conventional barrel look. A nut 38 threadedly engages upon the casing 32 and clamps against the inner side of the front wall of the frame 10 for the purpose of securing the casing upon the front Wall.

A stop 39 located to the front of the bolt 21, is pivotally mounted near its rear and by a screw 39 upon a bracket 39 secured upon one of the inner sides of the walls of the frame 10. A spring 39 is coaxially arranged upon the screw 39 and normally urges the stop 39 into a substantially horizontal position. The inner end of the stop 39 engages against the bracket 39 to prevent upward motion without restraining downward motion. The arrangement is such that when the detent 20 is moved downwards by the handle 27 the element 22 may flex so that the head of the detent may engage the head of the bolt 21. To accomplish this engagement, the stop 39 is pivoted after the detent has been engaged with the bolt, see Fig. 3, then the stop 39 again assumes a horizontal position and prevents the member 22 from flexing so that the head of the bolt can disengage from the keeper. In order to release the lock it is necessary that the barrel be rotated to cause the bolt 21 to rotate and disengage, from either side, of the detent.

A look mechanism is also arranged within the' frame 10, upon the side provided With'the openings 18 for the purpose of engaging the lugs insertedinto these openings. This lock mechanism comprises a plate 40 parallel with the side with the plate 40 to vertically hold a pair of superimposed plates 42 and 43.

The wall 10 and the plate 40 is provided with circular openings 44 and 45 respectively aligned with the openings 18. Small bulged covers 46 are atached upon the outer face of the Wall 10 so as to enclose the openings 45. The plates 42 and 43 are provided with opposed jaws 4'7and 48 respectively arranged in line with the openings 18, 44,

and 45. In Fig. 8 these jaws are shownin the A flange 33 upon the casing is.-

closed position. In Fig. 10 these edges are shown in the open position. A lug 49 from the plate 42 connects with the spring 50 which is attached at its other end upon a bracket 51 mounted upon the inner face of one of the walls of the frame 10 and arranged so that the plate 42 is normally urged towards the left, when the device is viewed as illustrated in Fig. 10.

A mechanism is associated between the plates 42 and 43 to move them in unison but in opposite directions. This mechanism comprises a lever 52 pivotally mounted intermediately upon the wall 10 and having arms 53 pivotally connected with its ends respectively and pivotally connected with the plates 42 and 43. A lug 54 projects from the plate and connects with a cable 55 which extends over a roller 56 at the corner of the frame 10. This cable 55 continues and connects with the lower end 5'? of the bolt 21.

Now referring to Fig. 11 a support frame has been illustrated. This frame comprises a Wall section consisting of vertical angle irons 60 adapted to bepermanently attached upon the wall of a house or other place. A transverse channel shaped member 61 is connected between the angle irons 66. A base section is pivotally mounted .upon the lower end of the wall section and comprises a frame 62 which is hingedly mounted by a rod 63 arranged between the parallel projecting arms of the angles 60. Springs 64 are arranged upon the rods 63 and act between the wall section and the base section to normally urge the base section into a vertical position. The base section is provided with a handle 65 by which it may be lowered into a horizontal position as illustrated in Fig. 11. If released the springs 64 will return it to the vertical position. A pair of spaced lugs 66 are provided with trapezoidal shaped heads (cam shaped) and are mounted upon the members 61 so as to project horizontal- 1y. The base. section 62 is formed with openings 67 arranged so that when in the vertical position the heads 66 extend therethrough. Washers 68 are slidably arranged upon the lugs and springs 69 upon the lugs act between the lugs and the washers for urging the washers against the heads of the lugs.

The operation of the device may be understood by first examining Figs. 1 and 11. The box por tion of the device may be attached upon the lock 66 by first lowering the frame 62 into the horizontal position as illustrated. Then the box portion of the device may be rested upon the frame 62 and moved so that the pin 66 enters the openings 18, passes through the openings 44 temporarily wedges the jaws 47 and 48 and are thus latched in place. The heads 66 of the lugs will finally assume a position behind the jaws 47 and 48 and Within the cover pieces 46. It is now impossible to remove the box. The cover may now be engaged upon the box. Some arrangement must be provided for attaching the rear end of the cover upon the box, for example, a hook strip 70 upon the cover is adapted to engage a lip '71 upon the top edge of the box. The other end of the cover is provided with a lock and the handle 2'7 may be depressed to cause the detent 20 to engage the bolt 21. The box is now in locked position and can be removed and opened only by authorized persons. Assuming that an authorized person wishes to open the box to place something in it, this per son merely engages the key 37 within the lock and turns the key so as to rotate the barrel 31 anticlockwise, see Fig. 7. This action mere- 1y releases the detent which is immediately urged into a raised position of the spring 36. Then the cover of the box may be removed and goods placed therein.

The box may be looked as previously described. Then assuming that it is now desired to remove the goods from the box and also to remove the box from the wall. This may be done by inserting the key 37 but this time rotating the key clockwise. This rotation will release the bolt 21 from the detent and simultaneously will draw the cable so as to draw the bottom plate 43 in one direction and the top plate 42 will move in the opposite direction die to the action of the arms 53 and the lever 52. This motion of the plates 42 and 43 opens the jaws 4'1 and 48 and then the box may be removed from the head 66 of the lugs. When the box is removed from the base section 62, the base section will automatically be raised into the vertical position by the spring 64.

While I have illustrated and describe the preferred embodiment of my invention it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United. States Letters Patent is:-
