JAMES E. DEBE, OF GULVER CITY, CALIFORNIA, ASSIG-NOR OIE ONE-FIF'.IIEJELWIHv T0 ANDREW K. MARTELL, F LOS ANGELES, CALIFORNIA. v Y' Application led Aprile,

To all whom it may concer/n:

Be it known that I, JAMES E. Dann, a citizen of the United States, residing at Culver City, in the county of vLos Angeles and State of California, have invented new and useful Improvements in Burglarproof Safes, of which the following is a specification.

My invention relates to safes and the main object thereof is to provide an improved burglar-proof safe' which may be instantly closed mechanically by depressing a pedal or electrically by pressing a switch, when a burglar is detected.

Other objects and advantages will appear hereinafter and while I show herewith and will describe a Vpreferred form of construction, I desire to be understoodthat I do not limit my invention to such preferred form but that various changes and adaptations may be made therein `without departing from the spirit of my inventionoas hereinafter claimed.

Referring to the annexed forms a partl of this specification :l l

Fig. 1 is a vertical section of my safe in open position. f Y v Fig. 2 is a vertical section of my safe in .closed position and before it is set for engaging and holding the cash box slide elevated when the safe is again opened.

Fig. 3 is a view similar to Fig. 2 with the parts set for engaging and holding thecash box slide velevated when the safe is again opened. Y

Fig. 4 is a side elevation of my safe.

Fig. 5is a fragmentary vertical section taken on line 5-5 of Fig. 4 showing one of the pedal connections. p Y Y Fig. 6 is a longitudinal section of one of the pedal hubs.v Y y y Fig. 7 is a cross section of the pedal hub shown in Fig. 5 taken on line 7-7 of said figure. l. Y v l Fig. 8 is across section of the pedal-hub taken on line 8-8 of Fig. 6.

Inthedrawings l'indicates an outer casing, 2 an inner casing, and 3 a cash box slide` which isw slidably mounted on the upper end of said4 inner casing. The outer casing 1 is closed by a lid 4Qwhich ishinged to the upper edgerof the rear wall of said casing by hinges 5 so that said lid may swing into the drawing which 1923. serial No. 630,802.

upper end of said casing against astop 6' in closed position. v

Pins 7 project from the inside of the upper ed 'e of the rear wall 'ofthe'casing v1 into soc ets 8 in the rear edge of. the lid 4 to prevent lifting of the rear part of said lid.k outrof the upper end of the casing 1 upon removal of the hinges 5 when the klid is closed. Y

A link' 9 is connected at its upper end to the under side of the lid 4 near its rear edge and at its lower end to the upper end of a sliding vertical rod 10 mounted in bearings 11 and 12 on the inside of the rear wall of casing 1. v

A collar 13 is secured on the rod 10'between the bearings 11 and 12 and a spring 1,4,- surrounds the rod 10 between bearing 11 and said collar which springy normally holds the lid 4 in closed position. Y

A trigger 15 is Vpivoted at 16 on a bracket 17 secured to the inside of the rear wall of the casing 1 below the, bearing 12. .Said trigger is formed with arms 18 and 19 and a spring 20 is interposed between arm 19 and a lug 21 on bracket 17 for holding said trigger in position with its arm 18 under the lower end of the rod 10 to hold the lid-4 open as shown in Fig. 1. The lower arm v19 rests adjacent the rear side of casing 2 i-n the path of travel of the slide 3. The casing 2 is adapted to lit detachably with the outerl casing 1 between vertical'guides 22 secured to the inside of the vertical walls of the casing 1. The slide 3is in the form'of a boxshaped casing formed with vertical walls 23, which telescope over the upper end of casing 2, and with an upper horizontal wall 24 slightly below the unner en ds of the vertical Walls, forming a tray 25 in the top of the slide in which rests the'cash box .26.

Dogs and 31 are pivot-ally mounted in the upper part of the front and rear walls of the inner casing 2 within slots 32 and. 33 in said walls respectively through which slots said dogs maybe swung outwardly into the path of travel Vof the slide 3. The dog 30 is formed at its pivoted end with asegmental gear 34 which meshes with a pinion35 journaled in the front Vwall of casing 2 within slotv 33. From the pinion extends an arm 36 and'from the dogy 31 depends an' arm 37 within the casing 2,

"side wall of the casing 2 through the lower ends of which arms extend a horizontal rod 38, said arms being` providedrwith apertures 39 and '40 respectively to'receive said rod.

On the outer ends of said rod are secured heads V41 and 42l and` collars 43 and 44 are secured on said rodY between and near the arms 36 and 37 respectively. A coil spring 45 surrounds the rod 38 between the arm 36 and collar 43. A coil spring 46 sur rounds the rod 38 between the arm '37 and collar` 42. A long lever 47 is pivoted at its Alower end 'at 48 in the lower partk 'of f a side wall of the casing 2 'and is connected at its upper end to one endo-f a spring 49, the other 'end of which spring beingconnected to a pin '49* in the upper part `of the casing 2. The lever 47 is pi'vo't'ed between its ends at 5() to the rod 38 between the collars 43 and 44. 0n the lower part of the lever 47 is formed a lug 51 'to be "engaged by a dog `52 which. is pivotally mounted in the lower part of a on a pivot 53. 'coilspr'ing- 54is interposed between the upper part of the dog 52 and a lug on the inside of a side wall of the casing 27 yfornormally holding said dog under the lug '51.` solenoid 56 Yis mounted in the lower part of the casing 2, the core 57 of which solenoid being connected to the dog 52. Y Y

vThe pivots 48 and 53 are journaled in vbearings 578 in the lower part of a sido wall of the casing 2 and extendthrough said side wall. Pins 59 extend diametricallythrough the pivots48 nand near the outer ends thereof. Pedals 60 and 6l 'are f'each `formed with a hub 62. each of which hubs having a longitudinal bore 63. extending from the inner end of the hub. a portion thereof, and with grooves 64464 and recesses -65, said grooves being at opposite sides of said bore vand -said vrecesses being at the inner ends ot'saidfgrooves and near the inner end of said bore. The recesses 65-65 extend diametrically oppositeeach other from opposite sides of 'the grooves 64--64. l

The hub .62 ot' the pedal 60 detachably fits on the pivot` 48, said hub Yextenditfigji,`

through an opening' 66 yin the lower part of a side wall or" casing 1 with said pivot `fitting in bore 63 and the Ypin '59 on 'said pivot resting in one end of the recessesy 654-65 away from the inner ends of the grooves (i4- 64, Yso that the pedal cannot be rremoved from the pivot without turning the pedal back until the inner end of the grooves 6464 registers with said pin 59 to enable the pin to pass out of the pedal hub through said grooves. In placing th'e'hub on said pivot the hub is turned backward l"so that the grooves 64-64 may receive the Apin 59 while the pivot 'is re mesme ceived by the bore 63 and when the huh is slid on the pivot until the pin 59 is opposite the recesses 65.-6'5, 'the pedal is allowed to turn down so that the pin passes into said recesses and engages the end wall thereof and the wall back of the inner ends of said grooves whereby the pedal is prevented from working ol said pivot.

The hub '62 of the pedal 61 is introduced through an opening 67 in the lower part of "a side wall lof the outer casing 1 and placed on the pvot 53 in the same manner as the hub of the pedal "60 is yi'il'aeed on the pivot 48.

My safe may 'be `secured to 'the Hoor 'by bolts 70 kvand nuts 71, 'said bolts extending through the bottom walls of the outer and inner casings V1 and "2 and said nuts screwing on the upper ends of said bolts against the bottom Wall of Casing 2.

The operation of my `safe vis as follows:

Assuming the safe to b'e closed as shown in Fig. 2, the pedal r6()` is v'tirs-t depressed which swings the lever '47 .to 'the v'right until the dog 52 springs under the 'lug -51 and holds the lever perpendicular as shown in Fig. 3. This movement of Vsaid lever moves the -rod 38 to the *right and Acauses the collars 42 'and'v43 to compress thesprings 46 rand 45 against 'the varms 37 and 36 respectively. Thelid 4 is then swung openon its hinges Vinto vertical position as shown in Fig. 1 Vagainst the tension of spring 14, and the slide 3 is Vlifted until its Ylow'fer edges escape the dogs 30 and 31, whereupon the dogs undertheiniluence ot springs 45 and 46 swing out from the casing 2 under said edges ot' said slide land support said slide, with the cash boX 26 in thetrp thereof, in elevated position as shown in iig. '1.

As the slide is iirst raised its lower edge diseng'ages the trigger varm '19, whereupon the trigger '15 under the influence of its spring '20 is swung to the leftunt'il its 'arm 18 rests under the lowerendf-'o'f rod Y10 and holds the doo1"4'open"throughsaid rod 'and link 9. It a burglar enters the building where the safe is located and at the point of a gun forces'the operator to hold up hishands, theoperatorp'utshis foot on'pedal61 and depresses it, which disengages dog 52tron1 lug 51, whereupon the spring 49"swin`gsthe lever 47 and the rod 38 to the left, andthe ,heads 41 and"44,'-engaging the Larms 3.6 and 37,1s`wing the dogs Y30 andfSl-inwardlyout of engagement with the lower edges ofthe slide3, which `instantly causes thev slide with vas lillustrated Vin Fig. 2.

lUU

The safe may be closed by the solenoid 56 which is included in an electric circuit 72 which also includes a generator 73 and a switch 74, which may be located in another room or any other suitable place. Instead of depressing pedal 6l the switch 74 may be closed, which will close the circuit 72 and the solenoid 56 will withdraw the dog 52 from under the lug 51 so that the lever 47 and rod 38 will swing to the left under the influence of spring 49, and the heads 4l and 42, engaging arms 36 and 37, will disengage the dogs 30 and 3l from the lower edge of the silde 3 and cause the slide to drop into the casing 1 and the lid 4 to swing closed over said slide as shown in Fig. 2.

Having described my invention I claim:

l. In a sate, a slide mounted in the safe, a door for the safe, means for holding said door open, means for holding said slide elevated in and above the safe, means for releasing said slide holding means from said slide so that said slide will be caused to move back into the sate, said means for holding said door open being engaged and 'released when said slide is moved back into the safe, and means for closing said door when said holding means is released.
