Figures 3, 4, 5 and 6 are cross sections on the lines 3_3, 4_4, 5--5 and 6--6, respectively, of Figure 1. n In many instances it is desirable that a closure have a frame, the stiles or equivalent elements of?which are of narrow width. For example, in the case of hospital windows and hospital doors nates a portion of a closure frame and B desig nates a portion of an associated closure which, having transparent panels, it is desirable that the door hinged at one side for swinging movement stiles be of as narrow width as practicable in between open and closed positions. Referring to the drawing in detail, A desig for present purposes, may be considered as a order that the windows and doors may admit 10 the greatest possible amount of light especially � ' The door B includes a frame b and a vpanel b' which, in the present instance, is illustrated as being of transparent material, although it may be in instances where the doors or windows are of narrow width. Also, it is quite desirable in many instances to provide a closure fastener embody of any other material. In any event, the frame b includes top and bottom cross members, only ing three latch or lock bolts, one at each end or ' portions of which are shown, and vertical ?side side of the closure and the other at an inter members or stiles only the one of which at the mediate point, all operable by a common mecha free edge of the door is shown. These members nism, and to mount said latch or lock bolts and preferably are of duplicate construction. They their operating mechanism in a door or window may, however, be of unlike construction. In any stile or its equivalent. ` 20 event, the stile at the free edge of the door and Accordingly, the general object of the present with which the presentv invention particularly is invention is to provide a closure fastener which concerned, is hollow andv of narrow width and is embodies three latch or lock bolts and a common closed at its outer and inner sides by walls I0 operating mechanism therefor, and- which is of and I I, respectively,` and at its outer edge by a quite narrow Width, whereby it may readily be 25 wall I2 which constitutes the free vertical edge mounted in a door or window stile or equivalent of the door. On the other hand, said stile which element of quite vnarrow width in any instance where that may be desirable. is designated as b" is provided at its inner edge with a slot?to accommodate the related marginal portion of the panel b'. To the end ofnaccomplishing the aforesaid gen eral purpose in a simple, practical manner, a 30 special object of the invention is to provide a latch or lock bolt which is pivoted for swinging movement between projected and retracted, latching or locking and unlatching or` unlocking � positions, respectively, and which is of a novel form whereby it is swung tooperatively engage its related keeper in response to_closing`movement of the closure. ' Y While the stile b" may be of any suitable con struction, it preferably i5 formed from sheet metal, its wall I D and I2 being, for example, in ` tegral with one another, as shown, and its wall Il being, for example, separate from its walls I0 and I2v to permit ready installation of the panel b'.

Thelatch orlock bolt 25 is pivoted intermedi ate its ends and adjacent to oneedge thereofY upon the pin 25 and includesa latching or locking , portion 2T which, by ,rotation of said bolt in one direction through an angle of approximately Y 'net-y degrees, is proiectable to a latching or lock ing position Yin which it extends beyond the stile wall I2; i. e., beyond the free 'edgeof the, door, as shown, and which, yby krotation of said locking bolt in the opposite directionthrough. an angle of ap proximately ninety degrees, is retractable to an 'unlatched or unlocked position in which it is dis- , posed entirely within thestile b? ?. , � i ` The portion 2'.' is substantially in the form of a ninety-degree segment of a circle as viewed* in side elevation and its inner face is of substantially conical remi; i. e., its inner face is beveled both longitudinally and transversely away from the pivot pin 25. Consequently,-should the portion` 21 - be in its projected position duringclosing of the 22 and' ?23 coi'istantly outward to .their limits of outward movement as determinedby engagement oi' the walls at the inner ends of the slots v38 in the stems 3l with the pins韎�. In this connection, the constructionobviously is such `that if the latch orlockY bolts 22 >and 23 are projected as shown` in lFigure __1, they will be retracted by inward movement ofthe rods 35, 35 and the tubes 36, 36. At the sameY time, the construction is such-that even though the rods 35 andthe tubes .35, -35 are not movedlinwardly, the latch or lock bolts22 and 23 are free to be moved inwardly against the springs遉, 42. vIn short?the籨escribed construc tion provides Yfor positively retractinglthe latch or lock vbolts 22, 23 when itis desired to` open the door` and, at the same time, provides for auto matic retraction of said bolts by engagement of their beveled inner faces with theirrelated keep ers topermit the door to be closed, as well as for subsequent spring projection of said bolts totheir door latching or locking positions when the door i is closed. . The block 25 is rigidly Connected with the bloes ` door, the beveled inner face of said portion will, Sethereabove bya bar _43. _, On the other hand, Yby reason of its wedging o-r cam action against the vblock 29is connected with the block 34 there- ' below through theA instrumentality o韆 rack bar the related keeper, designated as 28, cause said portion to swing to itsretracted position so as to ? 縤4 extending downwardly .from saidblocklg, a clear the keeper for subsequent projection behind rack _bar 45 `extending?lupwardly from' the` lower block 34, and a pinion rlliifnaying a rixed axis of latter.

The pinion 45 may?appropriately be 2,406,459 J mounted in a suitable frame 41 suitably fastened in the channel member It. In any event, it is apparent that the springs 42 tend constantly-to project both latch or lock boli-s 22 and 23 and to shift the block Z9 upwardly, and that by down ward movement of said block 2S, both latch or lock bolts 22 and 23 will be retracted. The block 2B is, of course, shiftable downwardly to retract ' the bolts 22 and 23 by means of the handle 33 10 operating through the lever arm 3 l. The lock or latch bolt 25 is located between the block 29 and the upper biock 34 and, inwardly of its pivot pin it, has projecting laterally therefrom a pin 4l" over which extends a finger 48 which projects laterally from the bar 43. Accordingly, when the bar 43 is shifted downwardly, the finger G8 acts upon the pin 4l? to rotate the latch or lock bolt 25 to its retracted position. On the other hand, a suitable spring 49 is provided to rotate said bolt 25 to its projected position when the bar 43 and the finger 4a are moved upwardly. Obviously, the finger 43 acts as a'stop engageable by the pin 4i' to limit rotation of the bolt 25 mentioned pin and the adjacent end of said stem and constantly urging said tube outwardly and said bolt outwardly relative to said tube, and means for manual actuation to move jsaid tube inwardly and thereby retract said bolt. 2.
