Ashape inftransverse, cross-section, a'daptedvto vover-lap one. upon the; other and to be :inserted vby one gof'itsj ,extremepor` tions and by itsv middle portion Withinlthe notch 320i the :jamb-B, theiremainingiextreme 9e portion of plates 6 and 7 projecting out of the door and the frame, the plate 6 having on its outside edge two integral bushings 6 and 6, and the plate 7 three spaced bushings 7, 7 and 7', of which bushings 6 and 7 have a complementaryY angular cut indicated by 6 and 7, and upon the bushings of plate 6 coming to register with those of the other plate 7, through the openings of the bushings is passed a pin 8 that has at an end a button 9 and at the other end has a screw thread for a nut or stud 10 to thread upon, there being a spring 11 coiled around the pin 8 and between bushings 6 and 7', which spring is adapted to force upwards plate 6, the latter Y being fixed to the side of the door 401" 5 with regard to plate 7, fixed within the notch 3 of the jambs 3 of the frame. The plates 6 and 7 have series of openings .12 and 13, suitably distributed and through which pass the screws that fix them,respectively, to the` door leaf and the frame.

In Figures 13 and 14, is shown a modified hinge, in which the coil spring 11 has been covered by a sleeve 11 fitted upon bushing T/l.

The door leaves 4 and 5 have on their free edges a deep midway cut forming a tooth 4 and an adjacent corresponding groove 4 on the door leaf 4 having their faces at anfangle and on the door leaf 5 the cut forms a tooth 5 and an adjacent corresponding groove 5, both having their faces at an angle and being adapted to clamp the tooth 4 of the door leaf 4 with the groove 5 of the door leaf `5 and just the same way, the cut or groove 4 of the door leaf 4 with the tooth 5 of the door leaf 5. (Figs. 5 and 6.) Y

Furthermore, each of the door leaves 4 and 5 is provided with a spring actuated latch 14, which cooperates with a detent 15 fixed to the jamb 3 of the frame, in order to lock in its closed position each door leaf. In

order to operate this locking latch and keep each door leaf shut, the latter has on its inner face and spaced at a certain distance be low the latch 14, a small hand lever 16 pivotally mounted upon an horizontal pin 17 fixed to the outside wall of a small box 18 fixed by means of a flange 19 integral with same and by means of a set of screws passing through holes of that flange on the inner face of each door leaf the small lever 16 having a stein 20 passing into the box 18 through an arched slot 21 formed in the outside wall of said box 18, to which stem is tied the end of a coiled spring 22 joined at its other end to a fixed point in the peripherial wall of said small box 18. The small box hand lever 16 works together with a detent 23 fixed to the side of the jamb 3 of the frame, so that when the end of said lever 16 rests against the shoulder of the detent 23 and forces the handle `of the small lever downwards, it will bring down the door leaf until the latch 14 is retained under the detent 15.

In the drawings is shown the door leaf 5 open, the groove 5 of same being separated from the rib 1 of the threshold 1 of the frame, the upper edge of said door leaf 5 resting into the recess 2 of the lintel 2. The hinges will be then in the position shown in Figures 9 and 10 of the drawings, that is, that the coil spring 11 will force the plate 6 upwards together with the door leaf 5 and the latch 14 will stay raised upon the detent l5. In order to close this door leaf 45, it will only be necessary to bring it down, which is done byvoperatingthe hand lever 16 as previously explained until the latch 14 is caught underthe detent 15 and in this closed position, the groove 5 of the door leaf 5 will adjustupon the rib 1l of the lintel 1, constituting a veritable dovetailed joint. In the hinges the plate 6 will have been forced down against the tension ofthe spring 11 until adjusting Vin a complementarywise way the angular recess 6 of the bushing 6 with the angular recesses 7 of the bushing 7 In order to open again the door leaf 5 it will suflice to disconnect the latch 14 of the detent 15 and to rotate upwards the handle of small lever 16 against the tension of spring 22 to enable the end of small lever 16 to be disengaged from detent 23 and then the tension of the spring 11 of each hinge will force the plate 6 upwards, carrying with same'the door leaf 5 until it takes the'positio'n shown in Figure 2. i

The same way the door leaf 5 opens and closes, the door leaf 4 does open and'close too, there being formed a tight joint between same by means of the cuts 4, 4 and 5', 5.

From the foregoing Vconstruction itwill be readily apparent the impossibility of the water entering the lower edge joint of the door leaves 4 and 5 with the lintel 1 of the frame, nor through the joint between that door leaves 4 and 5 and the corresponding door jambs 3 of the frame, due to the perfect closure afforded by the hinges with the door jambs 3 this invention rendering useless the water sheds of any kind heretofore employed on the outside of doors, shutters', etc.,to keep the water out.

Furthermore, the assembling between the lower edge of each door leaf andthe lintel ofthe frame provides a-V very strong grip l. A door hinged for swinging movement i and also for restricted vertical movement, and having a fixed keeper, a spring to raise the door, a spring-actuated latch to engage under the keeper when the door is in closed and lowered position, a second fixed keeper, and a lever pivotally mounted on the door and-arranged for coaction with the second keeper to force the door downwardly against the action of the first named spring and Vthereby cause the latch to engage under the rst-namedkeeper. v l

2. A door and vhinging and locking means therefor, as claimed in claim l, including also a spring active to normally disengage the lever from the `second keeper; v Y

In witness whereof I'afIiX my signature.
