or roar WAYNE, INDIANA DOOR SUPPORT Application filed February 11, 1927. Serial No. 167,486.

The invention relates to devices for securing doors and other articles in a fixed position to enable the artisan to work upon them.

In installing a lock in a door the general practice is to first hang the door and then install the lock. The door, of course, must be in open position to install the lock and it is necessary to temporarily secure it in that position. Generally wedges are driven under the door. These wedges frequently fail to hold the door and many accidents have occurred to the workmen because of such failure.

The object of my invention is to provide a tool by which a door may be firmly held in open position and which is simple to manufacture and to apply.

The invention is illustrated in the accompanying drawings in which, Figure 1 is a plan View of the tool in closed condition; v

Fig. 2 a side elevational view of the same in operative position; Fig. 3 a cross-section on line 33 of Fig. 1 and Fig. 4. a cross-section on line H of Fig. 1.

In the illustrative embodiment of the invention, the frame of in various forms. In the present adaptation, I form the frame of two side members 1 and 2, each of which is curved longitudinally downward toward its forward end. The forward extremity 3 of each member is suitably rounded to present a proper'surface for engagement with the floor. The rear ends of the members are preferably brought together to form a handle 4, the opposing parts being suitably secured together as by riveting or welding.

Forwardly of the closed end of the frame I pivot to both members a block 5 having a central threaded aperture 6 therein for the reception of the jack screw 7. A foot 8 is preferably pivotally secured to the rear or lower end of the bolt and the upper end is fashioned to form ahand grip 9.

Forwardly of the block 5 I pivot a stirrup 10 to both side members of the frame, the transverse portion or base 10 of the stirrup being disposed at a selected distance beneath the side members. Preferably the upper face of this base 10 is slightly convex.

the tool may be formed When not in use the jack screw maybe turnedto ahorizontal position as shown in Fig. 1. In use the open end of the tool is presented to the edge of the door 11 and the tool is then moved along the floor with the side members upon opposite sides ofthe door until the base of the stirrup has passed beneath the lower edge-of the door the proper distance. The jack screw, of course, has been swung to a perpendicular position. The screw is then rotated in proper direction until the. foot engages the floor. F urtherv rotation of the screwcauses the frame to swing upwardly, the forward end of the frame remaining in contact with the floor and form ing a fulcrum. Eventually the stirrup engages the lower edge of the door and further upward movement ofthe stirrup firmly locks the door to the floor. i

The stirrup and j crew are pivotally mounted onthe frame so that as the frame swings up or down these parts will accommodate the change in the angle between thefioor and the frame, and, exert/a positiveupward pressure onthedoorf V What Iclaim-is:v

1. A device of the class described consisting of a frame, a swinging member mounted on the frame and adapted to engage, the

lower edge of a movable object to be supported, and revoluble means mounted on the frame and adapted, when rotated, to engage a fixed object and cause the frame to pivot at one end whereby the swinging member is caused to rise and exert an upward pressure on the object.

2. A device of the class described consisting of a bifurcated frame adapted to engage at one end on a fixed object and to embrace the opposite sides of a laterally movable object which is to be supported, a transverse member pivotally mounted on the frame and adapted to be disposed under the laterally movable object and a screw pivotally mounted on the frame and adapted to abut a fixed object, and by the rotation of which screw the frame is caused to pivot on the fixed object to cause the transverse member to rig idly engage the movable object, the trans iii) " having laterally and mo b {means -my name verse member being located between the pivoting end of the frame and the screw.

3. A door support consistingof a frame, a stirrup pivotally mounted on the frame and adapted to engage the bottom of a door and a screw pivotally mounted on the frame and adapted when rotated to engage a fixed object and cause the frame to pivot atone end whereby the stirrup is caused to rise and exert an upward pressure on the door;

4- A. door supportconsisting of a frame adapted to embrace opposite sides of a door and to engage at endjdfthe frame members adapted to engage the fixed object. for raisingsaid end and causing the stirrup to firmly engage or elevate 5, A door support consisting of a frame havinglaterally separated side members, the forward endoffeach side member beingconvex on its lower side, a swinging door-engagingmember mounted on both said members mounted adjacent the opposite end of the frame and adapted to engage a fixed objeot whereby to elevate said latter end and said door-engaging member. 6; A door support consisting ofa frame separated side members adapted" to embrace the opposite sides of a door, a lateral member pivotally mounted on both side members, ancl'adapted to engage the bottom of a door, a revoluble member mountedon said frame and afoot pivotally mounted on the lower end of the revoluble member and adapted to engage the'floor when therevoluble member is rotated.

Inwitness whereof I have hereunto signed this 9th day of February 1927.
