To operate the latch the free side member ofthe panel has opposite arm 17 a hole 20,

and in a simplified form of the invention this hole may beA of small diameter, adapted to admit a'siiiall rod-like implement, such as a wire nail, which when inserted through the hole will engage arm 17 or a filler piece or pad '18"ther'eon', to raise thel'atch 'proper l1,

' here shown,v the hole 2O maybe internally threaded and a tubular screw p21 inserted therein. f This tubular screw providesa center bore through which a nail or similar yimplement may be insertedl to operate the latch in lthe' mannerl above described.

The outer end of the screw'has at'opposite sideskerfs or notches 22 to receive ascrew ydriver `or analogous implement. 'The latchv "may :then be'oplerated by inserting the screw driver bit int e screw notchesand'turning until the inwardl movement of the screw in contact ,withi arm 11' or its lpad-18' releases 'the hook.

WhetherI the latch operating iiieans lcohsists of ,a simple hole or a tubular screw, in

preferred cases I provide the hole or 'bore 20 c, A

ving access to thelat'ch for release of the'latch lvby* anelein'ent movedwithin the aperture,

at 'its outer end with inwardly cut' opposite Aslots or notches-23, s0 that the external'ap- "pearance of` the f hole'or c aperture is similar to that of a 'keyed lock. As otherwise described, the latch operating opening is camouflaged so thatunauthorized oruninf'ormed personswill believethat the panel can-be opened only by the fuse'poff a special key'and willnot make theattmpt, or 'if they do attempt to openf'it by'key manipulation, ysuch manipulation will be ineffective, and such v operating wth a fixed frame member, the

lpanel having -vtherethroughan aperture givunauthorized `persons will ,"'not understand that they latch maybereleased by a"V simple insertion `of a rod or use of a screw driver.

The'upper latch'8a, to cooperate with the upper frame strip 5 and afford added locking security, may beidentical with the'lower latch 8 except that the releasing a'rirr 17 may be omitted; and the two latchesare connected by a linkl 30,^'so that when the lower la'tclifis manipulated 'in the manner above described,

thevvupper latch is simultaneously operated.

Y While the'- complete structure 4 carrying the latches isv above described asf an exhibiting panel, it ,may otherwiseA bei a doorai'- close Aone or more panels'or card exhibiting frames, as shown in` one ofthe abovementioned applications, :and `in such cases the latch mechanismmay be applied to the door.

In certain of the appended` claims therefor y the term an exhibition panel or the-like is in the aperture.

in its broad sense inclusive of a door pivotally mounted in the main frame or casing.

I claim 1. In a structure of the character described, a frame having an opening for an j exhibition panel or the like, a panel pivotally `mounted therein, a latch pivotally mounted at the inner side of the panel and cooperating with a fixed frame member, the latch having'a releasing' arm and the panel vhaving therethrough an interiiall threaded hole, land a screw in the holecon ronting the latch releasing arm for latch release by rotation of the screw.

2. In a. structure ofthe character described,

la "lframeha'ving' an'opeiiing for.` an exhibition 'panel or the like, a' panel pivotally mounted ltherein, a latch pivotally` mounted at the inner side of the panel and ycooperating with al fixed frame'member, the latch having a releasing arm land the Y panel; having therethrough an internall 'threaded hole, and a tubular screw'in the ole, whereby the latch may be'released 'b AAscrew rotation or by insertionof'a rod-like implement through the s`crew.'-` 2 v "3.".In/a structure ofthe character described, arame 'havingan opening for an 'exhibitionppanel'or the like, a panel pivotlallyy mounted therein, a latch "pivotally mounted at the inner side of the panel and cooperatingwith a' fixed' raineineii'iber, the

panel 'having `therethrough any aperture givand another substantially similar latch coy"operating with' another fixed frame'inember, AVand anioperating iconnectionfroni one latch to the other.

4.2111 a struct-ure of the character describd,"a frame having an opening for aii exhibitionl panel or thelike, a panel pivot- I'ally `mounted therein, 'ar latch pivotally mounted'at thein'neiside of the Qpaneland coing access to the latch for release of the latch by an eleni'ent-movedwithin 'the aperture, the

iframeIneiiib'er or frame strip, andan operating yconnection from one vlatch to the other. 5. Ina structure yof Athe character described,I a* frame 'having an opening for an exhibition panel or the like, onezor Amore lhorizontal'strips crossing the opening, a panel' pivotally mounted in the opening, a

latch pivotally mounted at the inner side of the panel and' cooperating with one of the frame strips, the panel having therethrough an aperture giving access tothe latch for release of the latch by an element moved with- 6. In a structure of the character defbeing tubular, admitting insertion oi. a rod 4 scribed, a trame having an opening for `an' `like implement to engage the releasing arm.

` In 'testimo signature. e

7. In al structure of the' character de-y f scribed, a frame having an opening for an exhibition panelor the like, one or more horizontal strips crossing the opening, a panel pivotally mounted in the opening," a. latch pivotally mountedv at the inner side of the panel and cooperating with one of the frame strips, the panel .having therethrough an aperture giving access to the latch for release of the latch by an element moved within the aperture, the aperture 'having at the outer face of the panel opposite slots semblance of a key aperture.

8. In a structure of the character; dee

scribed, aVfra-me having van opening for an giving the n exhibition panel or the like, one or more hor-y y u izontal strips crossing the opening, apanel pivotally mounted in the opening, a latch pivotally mounted atthe innerk side of the panel and cooperating with one of the frame strips, the latch having a releasing arm and the panel having therethrough a hole aligned "L with thearm and permitting latch release byy insertion of a rod-like implement throughk the hole. e i e l 9. In a display structure for purposesde-L scribed, a frame having an opening for an s per and lower lat'ch-abutments supported by the frame,and upper and lower latchesy pivy otally mounted on the panel to cooperate', f with the abutments, spring means urging exhibition panel or the like, a panel pivotally mounted therein on a vertical axis, up-' the latches to engagement ,and av link connecting the latches to move together, one of the'latches havingl a releasing arm andthe i panel having confrontingthe arm an aperture providing for insertion therethrough of i a rod like implement to engage said arm and release the latches.

l0. The structure defined in claim 9`with the addition thatv the panel aperture is threaded, and a screw is located` in the threaded aperture with its inward end confronting the releasing arm 'and its outer end acccessible for rotationby a screw driver.A
