DOOR.

Application filed May 10,

In the operation of hospitals it is desirable to leave aja-r the doors to rooms in which there are patients so that nurses and attendants may quietly pass through and interior arrangements may be such that the patients will not be in full sight of persons who may be passing along the corridor but for the view afforded through the space between the door and jamb on the hinge side of the door as doors are ordinarily hinged.

The object of this invention is to provide a construction of door jamb, door and hinge which will not leave an opening between the door and amb on the hinge side of the door when the door is a-jar.

In the accompanying two sheets of drawings which form a part of this description,

Figure 1 is a horizontal section through a door jamb and door en'ibodying this invention. on the line I-I of Figs. 3 and a.

Fig. 2 is a similar section through the hinge on the line II-II of Figs. 3 and l.

Fig. 3 is an elevation of the door jamb to which the door is hinged with the door open.

Fig. 1 is an elevation of the same with the door jamb broken away on the line 1V IV of Fig. 8.

Fig. 5 is a perspective of the hinge.

Fig. 6 is a perspective view of a door embodying this invention mounted in position.

The door opening has the

usual door jambs

10, 10 and a head piece 11. As shown these parts are of pressed sheet metal but this material is not essential. The door jamb to which'the door is hinged has a corner bead 12 with a cylindrical surface of about one-half of a cylinder. This head is also provided for uniformity of appearance on the other door jamb and on the head piece. The head is interrupted 'or has gaps at the points where the hinges are to be located and the door jamb is cut away recessed or mortised at these points to provide space for the hinges. With the pressed sheet metal construction a reinforcement bar 13 is set behind the jamb at the recessed points and held in place by riveting or spot welding. Each hinge consists of a center pin 14, a plate 15 which is attached by screws to the reinforcement bar and aslip plate 16 which slides into a pocket formed behind a plate 17 which is attached to the edge of the door 18. A rivet 19 passes through the pocket and engages a notch 20 in the upper 1926. Serial No. 108,063.

edge of the slip plate. The hinge is positioned and attached to the and door so that the axis of its center pin will coincide with the axis of the bead and the edge of the door will lie in close proximity to the bead and remain so as the door is swung open.

Doors sometimes require to be removed and the usual method of detaching by withdrawing the center pins from the hinges is not possible with this construction. Unscrewing the hinges is'too slow. Therefore the slip plate connection is provided. \Vhen the door is open, it is lifted slightly to disengage the rivets through the pockets from the notches in the slip plates and the door can then be lifted away. It will be noted that by reason of the location of the pockets at the edge of the door and parallel therewith, the weight of the door does not come to any extent on the rivets through the pockets which engage the slip plate of the hi gges. Also by reason of this location of the pockets they are not in a conspicuous place and are entirely concealed when the door is closed.

I claim:

1. The combination of a door jamb provided with a corner bead having a cylindrical surface, the bead having gaps to receive hinges each hinge being set with the axis of its pin in line with the axis of the bead, and a door carried by the hinge with an edge in close proximity to the bead of the door jamb. v

2. The combination of a door jamb provided with a corner bead having a cylindrical surface, the bead having gaps to receive hinges each hinge being set with the axis of its pin in line with the axis of the bead, one plate of thehinge being attached to the door jamb, and a door provided. with pockets at its edge to receive the other plates of the hinges.

8. The combination of a door jamb, hinges, one plate of each being attached to the door jamb, and a door provided with pockets at its edge and parallel therewith to receive the other plates of the hinges, each pocket having a plate which overlies the hinge plate whereby the hinge plate is adapted to be held without the use of removable fastening means. 1
