To all whom t may concern.'

Be it known that I, HENRY II. AnnsoN,

a ycitizen of the UnitedStates, andaresident of Fairmont, in .the county of rMartin .and State et Minnesota, have .invented 'a certain new and usetul Burglarproot Device, :of which the following .is specification.

The object .of my invention is `totprovide :a burglar prooi device `oft very ,simple and eli'icient construction.

More particularly, it is :my objectto :provide a device of the general kind undericonh sideration, whereby fa closure Amember 'for a vault fdoor and :a closure Vmember ier fa .cash box are so arranged that upon the closing of :a switch, a -cireuit'may be closed `or qreleasing Ythe closure devices for zpreventing access to .the rvault .and fthe Vcash box.

iWith these and other ebjects in wiew, :my 2o rangement and combination .of the aricus parts ot' my device, whereby the Iobjects contemplated are attained, as hereinafter zmore full-y set forth, pointed out in ymy claims, e and 'illustrated in fthe accompanying idrawings, in which:

Figure 1 showszan inside or .rear elevation ot a bank vault adoor -or fthe :like A.equipped with :a lclosure member embodying my in- `Sie vention.

Figure 2 shows `a perspective view tot a portion :ot a bank counter 4having :thereon a cash boX equipped with my invention.

Figure 3 shows a vertical, sectional yview 3;, through the cash boX.

VFigure 4 shows ,a detail, sectional Aview taken on the "li-ne 1 1 of Figure 3.

Figure 5 showsfa-detail,sectional view of the locking device for the door closure anember; and

Figure 6 shows -a diagrammatic view of the electrical connections.

In the accompanying drawings, I 'have used the reference numeral 10 to indicate generally `the wall of Ethe *bank vault .or the like, in which :is provided -a door opening 11. On the inside of the vault andspaced laterally from the door 4opening on opposite sides thereof are mounted upright bars 12.

Pivoted to the bars 12 are laterally projecting members 13. f I provide agplurality ot the members 13 Vfor each bar 12. Pivoted to each set of members 13 are spaced closure bars 111, 15, and 16. Pivoted to invent-ion consists in the construction, .ar-v

each closure Ibar 16 is a Alocking bar 17 eX- tende'd 'through a guide or keeper 18 on the bar i12.

Mounted on `the bar .12 lb'e'low fthe locking bar 1-7 :is a A,pin 19 `and in ythe lower edge or the lbar 17 isa notch 20. In ithe upper edge'ofzthe'bar 17 .is a notehl.

Above the locking bar 17 is a swinging pawl `or `locking member .22.

W hen the closure. device, .just described, is Lopen, the members 13 are inclined upwardly, Vas `shown inFig-.ure .'1, and the linem bier 417 `is inclined downwardly eand laterally as show-n in said ligure.

It will `be seen that the closure .device tends :to drop by gravity to closedpiositinn, and when rit does so drop, the members '17 will slide vin the guides 418, iunti'l lthe notches 20 register with the pins 19, whereupon :the pins 19 will enter 4the notches 2O and the locking pawls 22 will swing downwardly with their ltree ends received in the not-ches 21, so that the bars 17 `can lnot zbesraised, lexcept Eby the use of a special vtool or `by fcnttfing them in two.

At'bove the ydoor Lopening 11 are two bars 22a ,pivoted together at adjacent ends, as 4at 23, and having near their -outer ends, elongatedfslotsl24, in which are received rpins2. 3V-hen `the lclosure members are raised, .as shown in Figure 1, the bars 22a are arranged substantially in alignment horizontally with their ends abutting against the upper ends of the -members 16, between the members 16, as shown in Figure 1.

'Ihe friction of the .parts will hold the closure member open. However, rowing Eto the `fact that the great weight of `the bars 22a 'is between the pins 25, the central 'portions of the bars 22 will tend vto drop downwardly, when their trictional engagement with the member 16 is releasedor when forced downwardly Vin any way.

lVhen the adjacent ends of the bars 22 are moved downwardly, their *outer ends swing upward-ly and clear the members 16, whereupon the closure member vwi-ll'd'rop by gravity to locked position.

Above the bar-s 22 is a guide 26, -in which is :mounted a. weight 27 having za head 2S. A trigger 29 is pivoted adjacent to the head 28 and has a projecting ringer -or the like 30, which can be made to stand below la portion of the head 28 for holdingthe head 28 in its raised position.

CIJ

Adjacent to the trigger 29 is a solenoid 31, having an armature 32. The solenoid is connected in an electric circuit by means of wires 33 and 34 with a source of electrical energy 35 and a switch 36.

I have shown a portion of a bank counter 37 on which is placed a cash box 38, preierably made of steel having an inclined sliding door 39 mounted between guides 40 and 41 at the sides of the cash box.

The rear guide 41 is in the term of a plate or partition, which extends trom the upper part of the box downwardly and iorwardly, as shown in Figure 3.

lVhen the sliding closure member 39V is down, the cash box is closed, and when it is up, ready access can be had to the interior of the cash box.

In the guide and closure member 41 is an opening 42 through which projects a tinger 43 on a Vtrigger device 44 pivotally mounted onthe inside ot the cash box.

On the inside of the cash box adjacent to the trigger member 44 is a solenoid 45, having the armature 4G. rthe solenoid 45 is connectedby wires 4T and 48 with the battery 35 and a switch 49. The switch 49 is connected with the wire 33 by means of a wire 50.

As many switches may be provided as is desired.

In the diagram shown in Figure G, I have shown a switch 51 located in a building at a distance from the bank. The switch 51` is connected by wires 52 and 53 with the wire 33 and the switch 36. The wire 53 is connected by a wire 54 with the wire 48.

Y Mounted adjacentto the side of the boX 38 in a recess 55 by means of a. pivot pin 56 is a catch 57, having a catch member or face 58 and a beveled face 59.

In the side edge of the sliding closure member 394is a notch 60. The catch member 57 is held in substantially upright position, as shown in Figure 4 by means of an arm 61, which engages a flat spring G2.

In the rear surface of the sliding closure member 39 is a small notch 63 arranged to receive the linger 43 when the member 39 is raised, as shown in Figure 3.

In the practical use of my improved burglar proof device, the closure member :tor the bank door is raised as shown in Figure 1. The closure member 39 is raised, as shown in Figure 3.

In case a burglar should enter the bank, any employeeffor otiicer, who is near a'switch can actuate the switch for closing the circuit. Switches can be placed on the floor or behind the counter or wherever it may be desired.

Then any one of the switches, for in stance the switch 49, is operated, a circuit will be closed. Y

vWhen the switch 49 is operated., a circuit will be closed from the battery 35 through the wire 4'?, the solenoid 45, the wire 48, the wire 50, the wire 33, the solenoid 31, the wire 34 and back to the battery. The armatures ot' the solenoids will be energized.

lVhen the armature 46 is energized, the trigger 44 will be drawn toward the armature 46, which will draw the pin 43 from the opening 63. The closure member 39 will engage the beveled edge 59, so that the catch member 59 will permit the closure member to slide to closing position, where upon the spring 62 will cause the engaging member 58 to enter the notch 60 for locking the closure member `39.

Wlhen the armature 31 is energized, the

trigger 29 will be drawn out of engagement with the head 28, whereupon the weight 27 will drop upon the adjacent portions of the bars 22a forcing them downwardly and forcing their outer ends upwardly out of engagement with the bars 16.

Thereupon the closure member 17 for the vault door will drop by gravity and be locked.

Thereafter the burglar will be shut out from access to the vault and the cash box.

It will be Vseen that my invention may be applied in a great variety of ways to fit the circumstances.

Switches may be placed in the `manner and locations desired.

The operation of the closure member for the vault door would prevent the burglar 'from locking the employees of the bank in the vault.

The cash, which the bank employees are obligedto have on thecounter for conduct ing current business should be kept in the cash box 38 in a cash drawer or the like,

which can be readily placed in the cash box or removed therefrom at night and placed in the vault. i

Some changes may be made in the arrangement and construction of the various parts of my device, without departing from the essential features and purposes of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

1. In a device of the class described, a pair of foldable closure members, adapted when open to stand in raised positions where they tend to drop by gravity to position forming a closure, a pair of bars pivoted together and piv-otally and slidably supported near their outer ends, so that when in substantial alignment their outer ends are frictionally held between the upper ends of the oldable closure members, a weight above the bars between their pivot supports, a trigger for supporting said weight, and an electric circuit including a solenoid and a lUU switch, whereby when the switch is closed the solenoid Will be energized for moving the trigger for releasing the Weight.

2. In a burglar proof equipment, a clo sure device comprising a pair of barred gate members, each consisting of an upright member designed to be secured to a Wall or other support, a plurality 'of cross bars pivoted to said upright bar, a plurality of spaced upright bars pivoted to said cross bars, a notched latching bar pivoted to one of the last-named upright bars, and a pin adapted to coact With the notched bar for holding the gate in closed position.

3. In a burglar proof equipment, a closure device comprising a pair oii barred gate members, each consisting of an upright member designed to be secured to a Wall or other support, a pluralityT of cross bars pivoted to said upright bar, a plurality of spaced upright bars pivoted to said cross bars, movable means for holding said gate in open collapsed position, means for causing releasing movement of said last means,

and means for automatically latching said 25 gates upon their movement to closed position.

Des Moines, Iowa, July 22, 1921.
