This invention relates` to certainnew and useful improvements in bank protectors.

The primary objectv of the invention is to provide a bank protector in the form of a 'shield or guard plate adapted tobefshifted into operative position for closing the window opening of av bank tellers compartment for the lprotection ofthe bank teller in theV event of attack from a 'bank robber or other "persons, the protector and its operating mechanism `being 4disposed rearwardly of the front Wall of a Ybank tellers `compartment or cage and obscured from view las well'as being automatically closing of the window opening. a With the above `and other objects in view that will become apparent aslthe natureofI the invention isbetter understood, the`v same consistsin the novel form,` combination and, ement of parts hereinafter more fully descri ed, shownin the accompanying draw#y invs and claimed.

lopening 10 yinV the front wall 11 'ofthe partition l2 formingthe bank tellers compartment, the outerfside of the front wall `11.` carryingvthe usual shelf 13 at-thelower endV of theI grated window opening 10.4 `The partiltio-n 12 rises from the floor 14 and carries a horizontal beadv bar l5 at its upper end.`

A casing containing the protector for-the gratedwindow opening 10 and the 'operating mechanism for the protector ,is suitably secured to the rearv side of the front Wall 11 and as shown inv Figure 7 ,comprises a bottom wall 16 flatly engaged with the Wall l1 and al top wall 17 spaced from the bottom wallbv edge flanges 18 'andsecured to the bottom wall by screw bolts 19 orotherjfastening devices.y

mechanismoccupies the entire-area of the the gratedy Window opening lOgthe top wall 17 of the casing carrying `a shelf or counter 21 at the 'base of the opening 20 andalignedv withl lthe outer shelf 13 as shown in Figure 2.`j`

The protector comprises a guardlplate 22,

v preferably of rectangular form and ofa size to close the grated window openingl() when in operative at each end. a substantially cylindrical rvinfr 'vertically Siidabie ,in :the

bearing block 25 position, having upper and lower.; edge flanges 23 and 24C respectively and car-vy 16 of the protector and mechanism'casingas,`

shown in Figures 5 and. 7-andengaged with 1 l f the closing movementof the guardplate relay tive to the grated window opening and `as Show in Figure 5; thef'stop block 28 rising* centrally of tlie upperflange 23 of the guard plate 22 moves into engagement withtlie pin partition 29 set into the head bar -15 of the 12'and tensionedby tbespring 30.` i

The mechanism `for placing the/i4 protector* or guard plate 22 yin set position against l f the Vtension of the op`er'alting'-springs 27 and Thecasing for the protectorand its operating 7,5` e

' a toothed clutch element the release devices for ,thel mechanism ,to` perpermitting mit operation of the springs is confined within the lower end of the mechanism casing and includes ahorizontal shaft 31 disposed below the tubular guides 26 and guard plate` and is supported at its ends in bearings 32 and 33.l The portion of the shaft 31 disposed below and between 34 rigid 'therewith and acooperating clutch element 35 free on the shaft 31 normally influenced into engagement with the rigid clutch member 34 by means of. the coil spring 36. engaging the free clutch element 35 at one'l of its ends and engaged at its other end with the abutment disk 37 on said shaft. A pair of cablesor cords 38 are fixed at one end as at 39 to. the lower edge flange 24 of the guard plate 22 in spaced relation with the other ends ofthe cords 38 secured to and wound upon the shaft 31 as at. 40. The operating means for the shaftBl include a bevel gear 41 fixed to the shaft 31 adjacent the bearing 32 that is in meshing engagement vwith the bevel gear 42 fixed to the shown in. Figs. 3. and

'ttt aaa si,L t lguard platerbeing wound upon `the shaft 31 lowering the guard shaft 43 that is journalled in the angularly offset bearing 44 carried by the lowery end of the mechanism casing. The outer end of the shaft 43 is of T-formation as. at 45 with 'which a key or crank 46 is engageable. as

shown in Figurel 2 to effect operation of the shaft43 and rotation of the shaft 31. bell crank leveris pivotally mounted as at 47 upon the bottom wall 16 of the ymechanism 48 thereof l forked for engagement with the free clutch element 35 as at 49 while the other leg 50 of the bell crank lever is` of angle formation and extends through the slotted opening 5l in the top,

wall 17 of the mechanism casing adjacent the floor 1 4 and carries an operating pedal 52 disposed within the bank tellers compartment.- v To lower the guard plate 22 to. set position 5, the crank 464 is enotaged with the shaft 43 to, effect rotation of ie cords 3:8 attached to the asfshown in Fig. 5 for plate against the tension of the springs 27. During this rotation of the shaft 3l, the free clutch elements 35 automatically escapey from engagement with the clutch element 3-.4 fixed n toy theshaftj 31 and when the guard plate 22 -f hasv reached its limit of lower movement, re-

verse rotation of the shaft. 3.1 is prevented by engagement of the two clutch elements 34 and 35the latter restraining the clutch elements 34and shaft against rotation byreasonl of thefmounting of the bell crank lever leg 4S upon the bottom wall 161 of the mechanism casing. In, the presence of impendingdanger to the bank teller, the pedal 52 is depressed for disengaging the clutch' element 35. from `the tension of the spring 36, thus freeing the shaft 31 and the tubular guides 26 has Aa bank tellers window,

)operable shaft.

the springs 27 to shiftv the vguard plate 22 in an upward direction to close the window vopening 2O and the grated window opening 10,y impactA of closing movement of the guard plate being absorbed by the ten sioned pin -29 set into the head bar 15 of the partition. 12. The setting and releasing devices for the operating mechanism for the guard plate are located at the innerl side of the front wall l1, entirely hidden'from view so ythat the front wall y11st itslouter side presents thel usualappearance of a bank tellers compartment. f c Vhile thereis hereinshown and described the preferred embodiment of the invention, it is nevertheless tobe understood that minor changes may be made therein without departing from the spirit and scope of the invention asclaimed.
