This invention relates to means for controlling open doors, to protect thedoor from contact with the wall and to prevent slamming or accidental closing of the door; and

' the objects of the invention are; first, to pro:

vide an open-door latch or holder which engages the knob of the door and holds the door open; second, to provide a stop at the wall behind the door in position to intercept the knob of the opening door, the stop having a permanent back stop and a spring supported i buffer which. yields to the pressure of the, door knob and absorbs or mitigates theshock when the dooris thrown back with force;

and, third, toprovide a combination of the latch or holder withthe stop whereby the holder is actuated toengage the doorknob when the knob bears upon the butter, and whereby the holder may be put out of opera- 0 tive relation to the buffer when the use of the holder is not required.

These objects are attained by the mechanism illustrated in the accompanying drawing, in which: p

Fig. 1 is a side view of the holder in combination with the stop. Section is made thru the wall plate and the housing on the line 11 in Fig. 2. A'door knob is in touch with the buffer without actuating the latch; Fig. 2' 39 is a face View 01 a wall plate on which all the parts of the combination are supportechthe' bufi'er being removed to show the' position of the crank by which the holder is actuated;

removed from the combination, secured to a sweep or guide which maintains the butter central with the opening in the wall plate; Fig. 5 shows a spring'based on the wall plate and tensioned upward against a flatted' portion of a crank shaft supporting the holder in position.

Aside from its combination with the door stop, a holder at the door knob so easily manipulated by hand to hold and release the door affords a convenience that may not be found in door holders atv the floor or on the bottom of the. door or' the base of the wall.

A door step encountering the door knob 'pre sents resistance to the violently'opened door nearer its middle and in some measure balances the strain on the door. -Th1S COII1b1 nation put no lncumbrance on the door and no obstruction onthe floor or the base of the wall, and in its position at the door knob it stands out but little from the wall in contrast to the outstanding stop that encounters the body of the door. The structure may be open-door position, a crank connected with the said door holder by which the holder is actuated, a buffer which is actuated by the knob of an open door and which actuates the said crank and thereby actuates the said door holder to engage the said door knob, a
