D. KAUFMAN PROTECTIVE APPARATUS FOR BANK WINDOWS AND THE LIKE Filed March l0. 1925 ATTORNEY DAVE) KAUFMILN, OF NEW YORK, N. Y.

PROTECTVE APPARATUS FOR BANK VIINDOVVS AND THE LIKE.

Application filed March 10, 1925. Serial No. 14,5%.

To @ZZ isf/loin may concern-i.' y

lie it lrnown that l, Dglvrn KAUFMAN, a citizen ot the United States, and a resident ot New York, in the county and State ot' New Yi'l, have invented an linproveinent in llrotcctive ppsratus for Baril: livinn (lows and the like, of which the following is a specification.

This invention relates to protective apparatns for benl; windows, cash booths and the like and nore particularly to such paratus' adapted for protection in case of hold-up.

@ne oi' the objects the invention is to provide apiieratus oi the above nature ot simpre and i 'actical construction and etticient action. Another object is to provide apparatus ot the above nature adapted to operate no itively and quickly and serve as a depenof-,ible protection against a sudden holdnp. @ther objects are to provide such apparatus which is conveniently installed and adapted to the condition ot practical use, and w rich when not being' operated is tinconspicnons and substantially unnoticeable.

Other objects will be in part shown or in t pointed ont hereinafter.

Mhe invention accordingly consists in. the features o'tl construction, combination ot eleincnts and arrangements ot parts which will be exemplified in the structure hereinafter described and the scope ot the application which will be indicated in the appended clniins.

ln the accompanying drawing in which are shown one or more possible embodiments ot the several tentures ot this invention,

Figure 1, is a rear elevation showing the jaratns annilied to a bank wV in open position, the window being of the tyife having one opening only.

Figure 2, is a rear elevation showing the apparatus applied to a window having a lower opening` and an upper opening, certain details not shown in Figure 1 being ineluded,

Figure 3, is a vertical section taken along 'the line 3 3 of Figure 2, v

Figure l, shows somewhat diagrammaticnlly a series ot windows fitted with the apparatus and ineans for joint operation,

`Figc-.re 5 is an end view looking troni the lett of Figure 1,

Figure 6 shows in perspective a portion of the apparatus in closed position, and

-dow and- Figure 7 shows in section a device for actuating the apparatus.

Similar reference characters refer to similar parts throughout the several views ot the. drawing. Referring now in ldet-ail to the drawing,

1 represents the body of a shield. guided by slides 2, 3. and held in open position by a latch l, said latch being pivoted on a yoke 5, and held under the protruding lip 6 ot the shield 1 by the spring 7.

A wire 8, Corning iroin an electric ineter tapped by the switch 9 and the fuse 10, is connected to the tongue 11 oit the jack 12. A wire 13, coining from the opposite pole of the saine meter, is tapped by the plug 14 and the fuse 15 and is then connected to one oi"- the poles of the inotor 16.

The wire 17 connects the motor 16 and the upper prong of the ack 12, the lower prong ot which by ineens ot the wire 18 tapped by the switch 19 is connected to one pole ot an electrical alarm gong 50, the other pole oi which is connected to the wire 13 by means o't a wire 20.

lli/Then the shield 1 is in open position, the linger 21 holds the tongue 11 of the jack 12 in contact with t-he upper prong of the said 12, (Figs. 1, 2) but when the shield 1 is closed, the tongue 11,y inade ot springy inetal, returns to its natural position resting upon the lower prong of the jack 12.

21 represents an arin bend carrying a inetal tube 22 havingl one end closed and the other sealed with insulating material einbracing the wires 24, The terminals ot said wires 2l, 25 are connected to an eloctrical plug 25. The other terminal of the wire 2e projects into the inside of the tube and the other terininal ot' the wire 25 is iirinly connected to said tnbe 22 having a nietal plunger 27 floating therein. Fig. 7.

ln operation the plug 14 is locked with plug 26, the switches 9, 19, are closed and the bend 2l is strapped to the arm et the cashier, in a position so as to cause the floating piece 27 to rest against the sealed end of the said tube 22. Fig. 7.

Suppose a robber should enter a bank, and standing before the windowV of the cashier, levels a revolver at his head and commands hini to put up his hands, or hand over the nioney; if told to throw up his hands, by doing so he causes the Hosting piece 27 to tall upon the wires 2l, 25 ot the tube 22,

closing the motor circuit; said inotor 1G being thus energized rotates and the lever 28 carried by the shaft of the motor 1G, butts against the latch 4 releasing the shield 1, the springs 29, 30 no longer held stretched, contract pulling downward the shield 1 closlng Sllne.

.it however the cashier is told to hand over the money, while appearing to do that, with his loot he can raise the pedal 31 causing the wires 32, 3B respectively connected to the wires S, 13, to bear upon each other closing the motor circuit. The niotor 1G is then actuated and thru the process above stated the shield 1 is released and closed.

Said pedal ill is placed along the floor under the windows; spring 34, holds it in a horizontal position; said pedal 3l can be readly operated by any one standing near said windows. Fig.

llhen the shield 1 is closed, the tongue 1l resting upon the lower prong of the ack 12, compl-etes the alarin circuit and the gong is caused to ring. lYhen the shield 1 is in open position the collapsible cover 35 hinged under spring tension to the said shield 1, is held in a vertical position by the Slides 2, 3 (Fig. 2) but as the shield il is released and nears its descent, the tongues 3G, S7 ojlf the cover 35, forced by the spring embodied in the hinge 51, pass thru the openings 38, 39 oi the slides 3, 1, and cause said cover 35 to swing away from the shield 1 and rest upon the surface of the bench (i.

The rear end ot the cover 35 has a V shaped wall, the apex of which is central h said cover 35 and 'faces the front ot' the shieltL 1 as shown in Figure (i. lllhen the shield 1 is released, it' it should happen that the robbers hand is caught between the bottoni ol the window and the released shield 1, the burglar in the effort of releasing hiinsali' may discharge his revolver, t ie V shaped wall et the cover S5 will detl ct the bullet roin its course and prevent possible injury to the cashier.

Tfart oit the lett side ot the shield 1 is toothed in a saw shape,y said teeth being` engap'eable with. a plunger il() held in a forward l Yfon by the spring` d1. It can readily be seen that as soon as the shield 1 is lowered, the plunger et() by engaging with the teeth of shield 1 will prevent saine from being raised.

ln its descent the shield 1, trips the levers L14 connected to the plunger 4G by the rod Said lever 1-#l in action pulls the plunger 4G from under the shields 1a, 1", releases the springs 30 causing the shields 1, 1" to close, it can be easily understood that with this arrangement, one shield 1 is sui'licient to operate a series of shields of the type 1, 1". F ig. (l.

Having thus described the invention what I claini is:

1. ln protective apparatus lor bank windows and the like, in combination, a bullet prooi? shield` positioned. at the rear of said window and slidable vertically, a latch inember holding said shield in raised open position, electrically operated means lor releasing said latch, ineans adapted to substantially instantly lower said shield to closed position upon release of said latch, a ineinber hinged to the inner side of said shield adjacent the lower portion thereof, means normally holding said member folded upwardly against saieL shield, and means adapted upon said shield moving doa'nv-:irdly to permit said meinber to swing downwardly away from the surface of said shield, said nieniber having a surface adapted to deflect bullets.

2. ln protective apparatus tor bank windows and the lil-1e, in combination, a bullet prooiA shield positioned at the rear of said window and slidable vertically, a latch adapted to hold said shield in raised open position, electrically operated nieans for releasing said latch, means adapted upon release of said latch to substantially instantly move said shield downwardly toward closed position, means adapted to prevent raising` ot said shield i'rom the position in which it comes to rest ai'iter release, and means hinged to said shield on the inner side thereof adapted to swing downwardly and close the opening beneath said shield should said shield be ,nevented trom moving to linal closed position.
