to have one or more gun ports located at strategic points whereby in case 'of a holdup or armed attack the bank employees or guards can defend themselves with'gunsfwithoutexposing themselves to the tire of the bandits.

However, in order to provide absolute Lprotection to the armed employees and prevent surprise attack by the bandits Vby the latter taking advantage of the gun ports or aperturesrbefore said employees can make use of them, it isy very essential that such gun ports be closed or sealed in such a manner that they Acan be opened only from the inside and can under no circumstances .be pried .or forced open Jfrom Vthe outside or that side which is presented to the public.

To this end, the present invention contemplates the provision of a gun port having an aperture presented outwardly and provided with a closure member arranged adjacent to the inner side of said gunport and normally locked in closed position by suitable locking means arranged on the inside of said gun port and not accessible tothe public.

@ther objects of the invention are to provide a gun port provided with agun aperture and having a closure plate movably mountedv on the inside of said gun port for closing said aperture and movable laterally thereolE into open position.

' Still other objects of the invention are to provide a gun portcomprising an outer member having a gun aperture and provi'ded'with a closure plate arranged adjacent to the inner side of said member and yieldingly held in closed-position, there being a locking mea provided 'for engaging said closure plate and locking it in closed position, said locking means being operable to release said plate by pressure applied to al partof said locking means arranged in exposedl position on the inner side of said gun port. y

Further objects of the invention are to provide a gun port comprising two Hanged inein-v bers which can be secured together j and clamped against an aperturedpartition wall,

the fouter member being provided with an outwardly presented aperture,there being a closureplate arrangedbetween said members wm @man 1 and adjacent to said aperture orclosing the f latter, said plate being movable laterally past -1 said opening whereby the barrel of a revolver canV be presented outwardly through said aperture, there being suitable locking means arranged between vsaid members for locking means being partially exposed through said inner member so as to' permit operation of said means by an authorized person to release said closure plate.

Additional objects of the invention areto provide an improved gun vport ofthe class described which can be readily attached in position and can be securely locked against opening from the public side of the gun Iiiortv said plate in closed position, said locking andwhich can be readily operated from the inside by pressure applied thereto by means of the lend of the barrelofA the. gun.

Beferringby numerals to the accompanying drawings, A indicates a bullet-'proof wall having an aperture B'which connects the'cusv tomers side C of the wall with the inside of the enclosure or employee side D. The wall A is in the instant case formed of non-shatterable glass but may be of steel or other material.

A gun port 10 is located in said opening and permits projection of a gun irom the enclosure so as to enable the employee to iire upon the bandits located on the other side of the wall without risk to his life.

This gun port consists of an `outer member 11, an inner member 12, and a closure plate 14. Outer member 11 has a body portion 15 disposed in opening B. This body portion is in the shape of a truncated lcone having an outwardly presented flared-out mouth 1G, the

inner end of which terminates in a central aperture 17.

lThe outer end ofl said body portion 15 terminates in a laterally disposed flange 18 which overlaps the outer end'of said opening B 'and lies against the outside faceofwall A. VPreferably a gasket of felt or cork 19 is interorm a seal therebetween.

The inner end of said body kportion 15 has formed lintegral therewith a circular wall 2O disposed in vertical plane with said aperture 17. vThe outside diameter of this wall is less than the diameter of opening B so that said body p rtion 15 and said wall 20 can be easily inserted therein. Y

This wall terminates in an annular rearwardly presented flange 21 exteriorly threaded vvfor receiving internally threaded annular Yf lf'in'ge 22 of inner member 12. The depth of 'ange 21 is such that a chamber E is formed .between the spaced opposed faces of wall 2O fand member 12 and the closure plate 14' is operatively arranged in said space. A set screw 23l is screw-seated in flange and engages flange .21 and serves to loclr the parts in assembled relation. f l v Flan e V22 is of suiiioient thickness to provide a earing tace 24 having suiiicient surfface Contact with the innerv faceof wall A in opposed relation to flange 18 of the outer lmember 11. A gasket 25 of felt or cork is interposed between saidk wall and face 24 toinsiire proper seal therebetween. Thus the gun port is supported in position by the clamping action of said flanges 18 and 22 and Acan be detached from the wall only from the inner side of said wall by the removal of inner member 12 and the outer face of said gun posed `between said flange and said wall to port is devoid 'of all securing or removable devices.

As stated before, closure plate 14 is disposed iny chamber E between the vertically disposed opposed "faces of inner member 12 and wall 20. -This plate is pivotally mounted y a pin or screw 26 to the face of the inner member v12 Aandis movable laterally or edgewise in said chamber E.

TheV inner member 12 is provided with an Closure plate 14 is formed with a straight edge 14a which when said pla-te is closed intersects said elongated opening 27 along a perpendicular line thereto and substantially equidistant from the ends thereof and well to one side of aperture' 17 as indicated by line Y-Y in Figur 2. .Thus with the plate 1e occupying closed position, only a smooth surface of said plate is exposed through aperture 17 as can be seen in Figure 1 while on the inner side, portion of said edge 14a is exposed through opening 27 as shown in Figure 2. i

A spring 28 cooperates with said inner member 12 and with said closure plate 14 and urges the latter into closed position.

A plate 29 is pivotally mounted at 30 on the inner face of member 12 for swinging movement to and from said face. This member overlies the end 276 of said elongated opening` and is provided with astraight edge 29a which is adapted to form an abutment` or close Contact with the straight edge 14a ot' closure plate 14 when the latter occupies closed position. Thus the contiguous portions of plate 14 and plate 29 are lexposed on the inner side of wall A through the e'longated opening 27 as shown in'Figure 2.

A spring 31 bears against one side of said plate 29 and yieldingly holds the latter against the apertured wall ofniember 12. Preferably plate 29 is pivot-ally mounted yon a block 32 and spring 31 is also secured at one end to said block and the latter in turn is secured to inner member 12 adjacent to the end 27?) as shown in Figures 1 and 5.

Plate 29 is considerably thinner than plate 1/1 and is so mounted that when in normal position or spring-pressed against the apertured wall ot member 12 that side of said plate which is arranged adjacent to the aperture 27 is disposed in the same plane with the l,

corresponding face' of the closure pla-te, the meeting edges 14a and 29a being flush. When7 however7 pressure is applied to said plate 29 through end 27?;7 as for instance, when the end oi aV gun pressed thereagainst, said plate 29 yields, thereby exposing the edge 14a of plate 14. Now it pressure is applied by said gun to said edge 11a so as to overcome spring 28, said plate is caused to move edgewise into a. position shown in full lines in Figure 17 thereby opening communication between apertures 17 and 27a `so that the barrel of said gun can be thrust outwardly into the outwardly iiared mouth 15. Thus the employee or person located on the inside .of

wall A can aim his gun in any directionexteriorly of said wall without endangering his life. f

' rflie free end of closure platell is provided with a radial extension 33 having a cani tace 34 presented toward plate ,29fand having a perpendicularly disposed face 34 presented in opposite direction. That end o'plate 29 located adjacent to the free end ofclosure plate 1l is provided with a flange 36 which lies in the path of travelk of extension 33and terminates in a hook 37aadapted when the closure plate occupies closed'position to en' gage the perpendicular face 35 and thereby lock said plate 14 in closed position. (see Figs. el and 6). rl'hus `under normal conditions closure pla-te leiis locked in closed position and cannot bc moved into open position until plate Q9 is pressed inwardly so as to disengage hook 37 from the extension Plate Q9 is comparatively thin-so thatsulficient clearance exists in chamber E to permitt-his v,pivotal movement of plate 29 withrespect to extension 33. The tree end of plate 11iis provided near extension 33 with a projection39 by means of which said plate can be moved man ually when the inner member 12 is removed from its position on the outer member 10. Both plates 14 and 29 are mounted on the face of member 12, thereby, facilitating the assembling of the operation thereof.`

ln order to strengthen outer member 10 a plurality ol' arms 40 is formed integral wit-li and extends between the llanges 13 and wall 20. i

The funnel or cone-,shaped mouth 16 and the location ot apertures 17 and 27 close togetlier permits the barrel ofthe gun to be presented forwardly within said mouth and pointed in any direction at an angle of fortytive degrees to the axis of the device. vThus the gun can be swung readily into position at any pointof acircle. This permits accurate aim otl the gun and considerably insures the effective range ot the gun.
