IThe entering efdge of arm member 20 is bevelled 'off as indicated at"Y `21 so that 5 f` it will readily enter the spacebetveen members 10' and 1 2: ,It is ,to be nosed that Vrriernber' 2 0 is. slightly shorter than arm member 14 soV that its outerend (that is the loverjendr when the` device isclosed) immediately above the base of arm member 14 and'abfove' the lpivot 16. This arrangement resultsin the center of gravity of combined members 14a'nd 2() being back of pivot 16 and gives inherentstability to the members ltand 20 .When they are folded up between members 110 and 12, andthisinherent stability plus the slight tension of spring 18 will be enough to keep them in place. Near its free end, arm member' 20 carries .a projection 22 IWhich will extend ontffrom be'- tween members 10 and 12 even when Ethe arms are folded np; fProjecton y2 2 is vsonriewliat thin ner than the main portion of arni `20 and this thinness vis carried down into the" arm 20" as indicated at'24.- The projection 22 has an .opening 26 v (see Fig. 6) which is yof the same shape astheA cross section of a bolt 2 8 carried bv the door 29 and ison1y just enough larger than the boltto give an ,easy l sliding 1"1t.

Thel movable jpor- 1#5 5 is provided for the tip 44 yof bolt 28 and the necessity for accuracy of adjustment ofthe bolt on the door isreduced. y

When' the device is not in use arms 14 and 20 will be folded up between members 10 and 12, with the opening 26 in line withl the opening 32 and bolt 28 will beikept in retracted position.,

When the door is closed, if boltf28 is shoved all theway out it will engage with "plate "30 and keep the vdoor locked. If it isfdesiredrto-leave the door ajar, or to open it so as to talk to someone on the outside whose identity is vnotl known, the .bolt 2 8 is retracted until thedetent 39 vengages its aperture Vindicating that movable portion 40 of the bolt is withinl'the opening '26 of extension 22 and `that'tip 44 is clear of plate `30. If the door is Ynow opened, the arms 14 and 20 will unfold, causing portion 4() of the bolt to pivot tothe position shown in .FigV 1. VWhen in'this position the tip 44 will prevent the bolt from being disengaged from arm 20L As shown' in Fig. 5 this opening of the door will cause considerable angular movement of the arms 14 and '20 relative bothto' thepivot 16 and to the bolt 28., This` angular movement is permittedby the fact that arm 1'4 is thinner than the distance between members and 12and by the fact that extension 22 is thinner thanmovable portion 40 of thebolt as well as by the normal bevel on the edge ofthe door. However, `itis advisable thatthe distance between members 10 and 12 be S0 .adjusted that 'whenv these arms' are fully opened, as shown in Fig. 5, arm 14 will jamb somewhat between the `two :members 10 vand 12 and also that the fit between vrthe `bolt 23A and opening 2 6 be such that arm l20r will bind around movable portion f4() when the angle is 'thus changed, as these adjustments will prevent rattling. It will also bev noted from Fig; 2 that the pivotk on the hinge connecting arms 14 and 20 is below a straight line from pivot 42 to pivot 16 and, as the hinge opens upwardly, thruston the door rwill simply serve to r*keep the arms opened full width. However," to :close the door either the hinge joint of' the two arms `may be pushed up or oneu can push down with `their thumb on the tipY of arm 20, readily starting movementbetween arms 14 and 20 which will Vof course be continued by pressure on the door.

` upper forward position.

Y From the foregoing .description of my device it. .willrbe seen that it is, one which can.` readily befmanufactured and which will serve to hold a door open against 4pressure without rattling (thus permitting the ldevice to be `usedas a ventilator) and in which a single bolt can be used either to keep the door locked tightlyor to keep it locked while permitting klimited movement.

What I claim is: l f

1. A device of the type comprising a box-like structure adapted to be attached to a door jamb and to carry a pair `of hinged members, the outer of which carries a recess and is approximately equal in width with the box-like structure, and a bolt adapted to ybe* attached toa door and engage suchrecess to ropen such members and thereby connect the door and the jamb structures, in which the inner of said members is lconsiderably thinner than the other and is mounted rin said box-like structure on a pivot 1having-greater exposed length than the thick- `ness off-said member and so that said member may changethe angularity of its plane relative to the pivot as well as to turn around the same, and in which the outer member ofsaid pair is of substantiallythesame thicknessjas the eig'- posed length rof said pivot, but in which said outer hinged member is vbevelled to approxi-' mately the width ofthe thinner member Aupon the edge first entering the box-like structure when the hinged members are yclosed so that angular movement of the' inner member upon its pivot will not cause the outer member to strike against the box-like structure to prevent the closing of the members.

` 2. A structure as Aspecied` Vin lclair.f1"1 which o further includes a spring member which tensions saidr thinner pivoted member s o that the latter tends normally to. assume a plane perpendicular to its' pivot.

3. A device'of the type'comprising a box-like structure adaptedy to beattached' to a door jamb and to carry a pair of Vhingedmembers,the outer of which carries a recess, -andl a bolt adapted to be attached to a door and engage Suchrecess to openl such members andA thereby connect the door andthe jamb structures, in which the box-like structure has an opening-in its front and said hinged members are adapted tof fold substantially within said structurewhen closed and the inner of said members has a leg extending under the other of said memberswhen they, are in closed position, the free end of which is mounted on said pivot so that when closed their center of gravity is behind the pivot i' towards the rear Aof the box-like structure whereby said hinged members tend to remain in equilibrium in said box-like structure.

4. A `device ofA the type comprising a box-like structure adapted to beV attached toa door jamb and to 'carry a pair of hinged members; the

6. A device of the type comprising a box-like structure adapted to be attached to a door jamb and substantially to house a pair of hinged members, the outer of which carries a recess,

and a bolt adapted to be attached to a door andv engage such recess to open such members an'd thereby connect the door and the jamb structures, in which one of said members is pivoted insaid box-like structure and is longer than the other and has a leg extending under the other member when they are in closed position in the end of which is mounted a pivot connecting said members to said box-like structure so that said member is pivoted off center so that its weightand the weight of the other hinged member, when the two are closed, tend to keep the members` closed and within said box-like structure, the other such membery being adapted to nest with the pivoted member approximately above said pivot point.

'7. A device of the type described adapted to lock a door in open position, extensible inner and outer arm members hinged together'adapted to open with the door in a perpendicular plane and to fold together substantiallyv within the box-like structure on the jamb, means connecting vsaid members to the jamb so that the members may swing laterally as the door isy opened, an opening in the outer of saidrnembers, a bolt slidably mounted upon the door adapted to enter said opening and extend therebeyond, said bolt having a rotatable portion intermediate its ends thinnerthan the width of said outer member and adapted to engage the opening in the same snugly, and a non-rotatable tip, said rotatable portion being adapted to rotate as the hinged members open perpendicularly, said tip being adapted to lock the hinged member in place upon the bolt, said rotatable,

portion fitting said opening in said hinged member so that the same tends to bind when the hinged members are opened, whereby rattle is prevented.

8. In a door check, a box-like structure attached to the jamb and having an opening, an inner hinged member 'of L-shape with a long and short arm and pivoted to the box-like structure by the short arm towards the outer end thereof y.so as to move in a Vertical plane and laterally and so that the long arm extends upwardly into the rear of the box-like structure, an outer hinged member having a projection withv an opening attached to the upper end of said long arm by a rule joint, said outer member when the hinged members are closed lying'` above the short arm of the inner hinged member so that their combined center of gravity is behind the pivot point towards the rear of the box-like structure, said hinged members adapted to open and close in ageneral vertical plane and when closed to fold together Within the box-like structure except for the projection upon the outer arm, and a bolt attached to the door adapted to` engage said opening in said outer hinged member so that said hinged mem- Vbers Will open when the door opens but so that movement of the door will be limited by the length of the hinge members.

9. In combination with a door, a jamb, a bolt of non-circular cross section on the door carried externally and visibly thereof, said bolt having a rotatable portion intermediate its ends and a non-rotatable tip, a pair of members hinged together with one hinged to the jamb and the other carrying a projectioniwith an opening extending beyond the jamb adapted to receive the end of thebolt when such members are folded up andadapted to pivot around the bolt behind such tip upon the rotatable portion of said bolt, a fixed projection on the jamb having an opening aligned with the opening in the first projection and adapted to receive such bolt, and means for maintaining such projections in spaced relation so that Such bolt may be positioned in the rst projection with its tip extending therethrough Without engaging the second projection.
