rlhis invention rela-tes to improvements in door holders and resides inthe provision of a simple and inexpensive device of this nature which may be quiclrly and easily .in-

stalled and will operate Vautomatically incident to the opening of the door into a pre- @determined position to engage and holdthe door against,unintentionalclosing said de- Y vice being moved to release .the door when A le the dooris intentionally moved as when closing the'same. y

An object of the invention is to provide a door holder of the character described which has a moment of inertia sufficient to hold .itself in any position 'into which it is moved onthe surface on which the door holder is arranged, whereby when the door is engaged provide a door holder of the character def'v scribed which is provided with a simple but with the holder, said device will hold the door against unintentional closing.

A further object of the invention vis to eiective means for locking` the holder against movement, whereby the door maybe iocked againstrclosing except when forcei -fully moved to close they saine,'the employnient of said means being desirable in somey Y, instances where the doors are subjected to heavy wind pressures erV drafts whichrmight besuiiicientto overcomejthe inertia moment of the holder. i

A further object ofthe inventionis to provide a holder ofthe character described which may be quickly and'easily installed without necessitating any change in the con* struction of the Hoor or in the door.y

W'ith the above mentioned, and Yother ob;

'ects in view the invention consistsin the Y 7 Y novel constructionand combination of parts hereinafter described, illustrated in thefaccompanying drawings, and set forth inthe ,claim hereto appended, it being understood that various changes in the'form, proportion,

size and minor details of construction within the scope of the 'claim maybe resorted to without departing from the spirit or sacri- `ficing any ef the advantages'of the invention.
