Toall whom it may concern: t

Be it known that I, ALEXANDER C. `Os- BORN, a citizen of the United States, residing at Clarksburg, in the county of IjIarriso and State of West Virginia, have invented a new and useful Automatic. Door, of whlch the following is a specicatlon.

This invention aims to provide novel means for mounting a door for swinging movement on a horizontal axis, the construction being such that when the door is open,

' it will stand in an inclined position and serve as an awning for the doorway.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to wlnch the 1n vention appertains. A

In the accompanying drawlngsz-j Figure 1 shows in elevation, a devlce constructed in accordance with the invention; Figure 2 is a section on the line 2 2 of Figure l; Figure 3 is a similar sectlon, thegdoor being in open position; and Figure 4 1s an elevation showing one of the brackets and attendant arts.

In carrying out the invention there .is provided a frame, denoted generally by the nu-` meral 1, the frame including a sill 2, stiles 3 and a lintel 4. Lower stop strips 5 are mounted on the rear edges of the Stiles 3 and extend upwardly from the sill 2. An upper stop plate 6 extends between the ustlles 3 and projects downwardly from the llntel Brackets 7 are mounted on the stlles 3, each bracket including ianges 8 and 9 disposed at right angles, the flanges 8 being connected to the stiles 3 by securing elements 10. The anges 9 are suppliedwith outwardly extended bearings 11.

A barrier 12 is disposed within the frame 1 and a transverse cleat 14 is secured vat 15 to the barrier. A shaft 16 extends longitudinally of the cleat 14 and transversely of the barrier 12 and is attached to the cleat by securing members 17. The shaft 16 is provided at its ends with journals 18 mounted to rock in the bearin s 11. A weight 19 extends transversely 0% the barrier 12 and is located at the top thereof, the weight being strips 5. The cleat 14 setszrhe shaft 16 forwardly to'such an extent that the center of mass of the weight 19 is slightly-to the rear \of the axis of the journals -18,"and, consequently, when the barrier is vinthe closed position shown in Figure 2, the barrier does not tend to swing to anopen position, responsive to the weight 19. The barrier 12, however, maybe swung upwardly intov the open position shown in Figure 3 until the barrier comes in contact with the stop plate 6, the weight 19 serving to hold the barrier in the posltion of Figure 3, under which circumstances the barrier will serve as an awn- -ing or canopy, the barrier being downwardly inclined to a slight extent, so as to shed rain. v

The weight 19 preferably is made in sections, as shown at 60, to render the weight easier to handle during the building of the device.

Having thus described is claimed is In a device of the class described, a substantially vertical frame including Stiles, a sill and a lintel, a stop plate projecting downwardly from the lintel and locatedbetween the Stiles, brackets on the forward edges of the Stiles and projecting forwardl therefrom, means for securing the brackets to the forward edges of the stiles, a shaft mounted at its ends to rock in the brackets, a barrier located between the shaft and the stop late and abutting at its upper end against t e stop plate, a weight secured to the barrier and located above the shaft, a cleat interposed between the-shaft and the barrier, and means for securing the shaft the invention, what and the cleat to the barrier, the cleat con'-`
