My invention consists 1n the constructlon,

arrangement and combination of elements hereinafter'set forth, pointedxout in my i vclaims and illustrated by the accompanying Y drawing, in which' 3 v g Figure 1 is an elevatlon', partly in section, showing my improved device mounted in position for practical use, a portion of a door being indicated by dotted lines in positionfor engagement with the device. Fig- "ure 2 is a plan of the sa-me'elements, the position of the device after engagement by the door being indicated by dotted lines;

In the construction of the device as shown 40 the numeral lOdesignates a tubular support, such as a section of gas-pipe, adapted to be mounted in a vertical position in the ground or in a cement driveway adjacent a building such as a garage having swinging doors with support projecting above'the surfaceto a point somewhat below the horizontal plane of the lower margin of the door, such as 11.
