If, however,

and screw-holes c are formed in said flanges the door is to be temporarily locked, this may be readily effected by movement of the locking-bolt 7, so as to locate it above the hooked end of the latch-bar 6, which will prevent the latch-bar from rising sufficiently to disengage the hook e from the catch-box and therefore lock the door until the bolt 7 is removed from over the latch-bar.

In Fig. 2 is shown a modified form of the latch-bar to adapt it for adjustment endwise, so that it may be increased or diminished in length to suit difierent widths of door-casement jambs. In this construction one end of thelatch-bar body 6 islongitudinally movable in the transversely-slotted footpiece d and is perforated at short' intervals, these perforations h being adapted separately for alinement with mating holes in the slotted footpiece cl and for the reception of a securing-screw 71, whereby the latch-bar maybe adjusted endwise to give it desired length, as may be required.

Having described my invention, I claim as new and desire to secure by Letters Patent 1. A door-fastener, consisting of catch-box adapted to be secured to a door and provided with a central opening in its front wall and with a transverse slot in its top Wall, an adjustable spring-bar adapted to be secured to a door-casement and provided at its free end with a V-shaped hook adapted to enter the opening of the box and engage the front wall thereof, and a bolt loosely held in the slot of the box and having its lower end extending down into the box, said bolt being adapted to be moved in the said slot to dispose it directly over the hook of the said bar or at one side of the same, as set forth.

2. A door-fastener, comprising a catch-box adapted to be secured to a door and provided with an opening in its front Wall and with a transverse slot in its top wall, a spring-bar adapted to be secured toa door-casement and having a hook-shaped end adapted to enter the opening of the box and engage the front wall thereof, and a bolt slidably held in the slot of the box with its end extending down into the same, the said bolt being adapted to be disposed directly over the hook of the bar or at oneside of the same, as setforth.

3. A door-fastener, consisting of a box having an opening in its front wall and a slot in its top wall and adapted to be secured to a door, a bolt slidably held in the slot of the box with its end extending down into the same, a slotted footpiece adapted to be secured to a door-casement, and a spring-bar having a plurality of openings for adjustably securing it to the slotted foot, and provided with a hook at one end adapted to enter the opening of the box and engage the front Wall thereof, as set forth,

In testimony 'whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM BUTLER COOHRANE.
