.To all whom it may co'rwein.'

`Be it, known' that I, Louis MYERS, a citizen of the United States, residingin Newark, county of Essex, and State of New-'Jersey, have invented certain new and useful Improvements in Safety-Chests,aof which the following isl a Specification.

. My present invention relates to improvements in'safety chests or receptacles adapted to contain jewelry' or other valuables, and

rovided with an automatically operated urigla'r. alarm designed to prevent the theft of t echest or the removalof ,its contents. A

In general design the chest proper of my present invention is of Isubstantially the same construction 'as covered by my pending application filed lMarch 22nd, 1967, Serial The improvements in my present case relate to the 'lookin mechanism for the chest,

and to an electric alarm mechanism,` auto- .f matically controlled byfan unstable ball or weight, and `having means actuated by the locking niechanism'for settingV and disconnecting t-he alarm mechanism so that the .alarm will be placed'in condition for opera'- tion when the'chest is locked, and will be chest is unlocked.

l thrown into inoperative position when t-he In order that'my invention may be fully understood, I will first describe the -same i with reference to the accompanying drawings, and afterward point out the novelty 'the chestv being broken away. to exposethel ymore particularly in the annexed claims.

` In said drawings Figure 'l is apfront elevation of my improved safety chest showing the cover raised into' open position, a part ot of the, cofvershown in Fig. 1, with the locking mechanism in shifted and'locked posi-l tion.` Fig; 6 is a vdetail side elevationof two of the locking bolts and their operating mechanism. Fig. 7 is a detail planjview of a partof themainbod of the chest illustrat-iner the spirit levels or leveling the chest upon its support, and also showing one of the bolt receiving so'cketsor o enings. y

The chest proper is prefera lyformed of inner and outer spaced shells 1` and 2 as fully set forth inmy above named applica tion Serial No. 363,883.' Since it is'necessary to the'proper operationof my improved automatically controlled alarm mechanism that the .chest be placed upon a perfectly level surface, I provide the spirit levels5 and 10 `in the upper edge of the walls of the main body-of the box as shown in Fig 7.

15 is the top of the box or chest which. is"

preferably Vformed of inner and outer walls or shells as described :in my above named application. -This top may be hinged to the'main body of the chest or it may be entirely removable therefrom.- I have 4not shown the details of the mounting of thek cover upon the box, but the cover is preferably ningcd at one of its long edges'to the upper edge of the box proper.

Lprefer to mount the locking mechanism and the alarm mechanism-entirely upon the cover, placing these mechanisms upon the vinside of the cover so that they areentii'ely inclosed and 'protected when. the -chest isl closed and locked.

It will be observed particularlyvwith ref; ei'ence. to Fig. I that the upper edge of the' main body portion of the chest is formed with bolt receiving slots-or-.keepers 20, it being preferable to provide four of such keepers 20, one near' each corner ofthe box to receive the locking hooks 25 formed integral witli the longitudinal movable locking bolts 26. There are four of these locking bolts 26, each one of which is provided with two longitudinalslots 2'( in which engage the guiding and retaining pins 28 rigidly .mounted inthe flanged portion of the cover These locking bolts 26 are arranged -betweeii the inner and outer walls of ythe cover of the'chest, the` guiding pins' 28 being mounted inV said walls.4 The locking hooks of the bolts 26 project through slot-s 29 in the facing flanges 30 of the cover.

35 and 36 are bolt operating levers pivotally mounted at 37 upon the yinner face of the cover 15. The opposite ends of each of these Ioperating levers 35 'and 36 are slotted or forked as indicated in'dotted lines in Fig.-5 to engage the pins l38 upon the y locking boltsv 26, so that whenthe levers 35 manner. i

'and 36 are moved upon their pivot 37, all

of the locking bolts 26 will be correspondinglymoved inwardly or outwardly into 'unlocked or locke position.

For controlling and actuating the operating levers and 36,l I havearrangeda rock-ing arm or lever 46, centrally journaled upon the im?? face of t'he'chest4 cover at 41, and carrl vlng in its opposite ends the laterally projecting pins or lugs 42, which, engage .andoperate in the camV slots 43- formed in the operating levers 3 5 and 36, andextending at an angle to the longit-u'-, dinal axis-ot said levers. When thelever is rocked, pins 42 will cause the ' levers 35 and 36 to be correspondingly moved forop erating the bolts.

is a permutation locksuitably mounted i in the cover ladjacentfto the front edge and l.having-the operating-"knob or handle 51 projecting outwaidlyin 'convenient position to be operated. This permutation lock 50 is of ordinary constructiomand is not illustrated in detail in the accompanying drawings, except to show a plurality of tumbler disks 52, each one of which is' formed with. a

notch orgate 53 in the usual 55v is a dog 'or detent pivoted at 56 `and having are'ctangularly projecting nose 5511 which' fis v'adapted to engage and enter thev ates 53 of all the tumblers, when the comination .of the'lock vhas been properlyset. A .leaf'spring 57 mounted upon the rocking leverlO engagesthe dog Aordetent 55 and movesit intol engagement with the gates of.

the tumble'rs when the tumblersi have been set;-. By 4this means the dog or detent 55 is engaged by the rotatablepermutation lock so that the vlever 40 can be rockedupon. its

pivot 41 for actuating'the levers 35p and 36 'toV thereby move the locking bolts into and 'out of'locking position. j l

60' and 61 are the bells and 62 1s the hammer of an'ordin'ary electric bell. The hammer 62 isfiounted upon the spring actuated armature' lever 63Avvhich is mounted in operative relation to theelectro-.magnets 64.

65 is abattery. mounted -in a compartment in one end of the body portion 4ofthe chest,

' and l66 and 67 are thebattery terminals. A

-wire indicated .at 69 isrun from the battery terminal 66 to the bell terminal 68. Another wire indicated at 70 is run from the batterv terminal67 to the end of'a Contact lever .71. hereinafter 4referred to, and a third wire 1n` contact 73, -the bells 6() and 61 will be sounded.

vis a hollow cylindrical box secured to the inner face of the cover 15 of the saiety chest.' `This box 8O is preferably formed of 7@ some insulating materialA such as rubber, tiber' ori-porcelain. This box 8(),.is lsecured to .the facer of the chest coverl by longV screws passing through it into .the cover as shown at 81 .and ,82. A circular'opening -85 i575 forined in the inner wall'of the box or cover to receive a small conoidal block' 86, which-is .mountedl upon and projects upwardly from the contact lever 71. This contact; lever 71 is freely journaled upon a screivfST, and is engaged by leaf spring 88 secured to the box '8K0 at 89, so as to tend to move the' contact endof lever 71 into engagementwith conA tact 73', and 'atthe same time elevate the conoidalblcck "86 'in the opening 85 of lJOXSO.l 'l i 'si 90 isa spherical weight freely mounted in the cylindrical'cavityl 80? of box 86 so as t0 be capable of rolling around therein'under the influence of the displacement (if-the Chest.v

lWhen the box is supported .in perfectly level` position and the Contact lever- 71 is held in position tof breakI the electric 'circuit and holdl theconoidal block 86 downwa'rllly in the opening 85, the spherical weight -90 w il1..

naturally rest in the opening 85, said open- 'ing' altordmg a slightdepressionor seat for retaining 'the spherical weight in that p0-y sition. I

95 is a throw-outvlever pivoted uponpthe inner end of the bex-80 at 96 and having one end* projecting through a slot 97 formed lever will be rocked upon its' ivot every time the bolt is shifted longitudinally. The-i opposite end of the throw-'out lever 95 is formed with a-laterallyv projecting ,curved' blade which is presentedin the channel 80b cut transversely across the end of the box 80 in position to engage the free end 71* of the contact lever 71 to move the contact lever into inoperative position. This throw-out lever 95 is operatedfor breaking the circuit controllingfthe electric bell when thebolts 26 are unlocked.

*The operation of the device'will be clear from the'- Afollowing brief description: The 4safety 'chest is placed upon a table or other support and arranged as nearly as practica` ble in level position. The valuables being placed in the chest, the cover is closed. VV-hen vthe 'cover isV closed, and before the 'bolts are locked, it willjbe observed that the throw-out lever 95 is Vin positiouto engage a i a the-contact'lever 71 so that the circuit tor i,

the electric bell is broken. This position or' the throivfout lever 95 also holds the eonoidal block 86 withdrawn partly from the opening 85 in the hollow block 8U. so that the ball or weight 90 will have come to a position of rest in engagement.A with the opening 85 as shown in full lines in Fig.

of the drawings. The lock vmechanism is then operated for locking the chest and the combination disturbed so that 'it cannot be unlocked without a `knowledge of the combination -As the bolts are locked it will bel observed that the throw-out lever 95 is with-y drawn'out of engagement with the contactlever 7l so that the spring 88 will tend to -move lever-,71 into position to 'complete the circuit-which rings the bell. lVhen, -liowever, the lever 95 is withdrawn, the ball or weight 90 .is in 'a position ot rest above the opening 85 so that when the spring actuated contact lever 71 is released, it will m'ove .the conoidal block 86 gently up into engaement with the ball or weight. 90, the

`weig t of which is sufficient to withstand the pressurev of the' spring 88. In thisv position the ball or Weight 90 holds the contact lever 4out of contact with theplate 73 so that the chest may remain in this set position untildisturbed. If the box should be'shaken or moved from its'horizontal position, the ball or weight 90 kWill immediately roll away from its position vof rest above the -conoidal block- 86., which will permit the spring 88 to force the ylever 71 into contact position, lwhich will cause the electric bell to ring. The moment this action has taken' place, the conoidal rblock 86 will have assumed a position projecting up through the opening l into the box 80, sotliatthe ball orweiglit 90 cannot by any possible means be replaced in -position to break'tlie circuitand stop the alarm. The bell will, therefore, .continue to ring, and will attract attention to the unauthorized disturbance of the chest, until the chest is unlocked by the person having knowledge of the combination. Then the chest is unlocked, the electric circuit is broken as above explained,'and the alarm arrested.

It will -be observed from Fig. 2 of the drawings that the sound from the electrical alarm has free outlet through the openings in the inner wall of the cover 15 and through opening lOl. in the outer wall of the cover into the perforatedl raised crown` pli'ece 102secured to the top of .the cover.
