ATTORNEY TATES ar a s JOHN BURCH, or spam, onneon DOOR-OFEBATING MECHANISM Application filed March 231, 1928. Serial No. 253,433.

My invention relates to improvements in door operating mechanism and more particularly to means for opening and closing the doors of garages and the like.

The primary object of the invention is to provide mechanical means for opening and closing the doors of garages which is operable at a remote distance therefrom.

A further object of the invention is to provide means of the above-mentioned character which is simple and durable in construction, readily installed in the conventional type of garage, reliable and eflicient in operation and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing, forming apart of this specification and in which like numerals are employedto designate like parts throughout the same,

Fig. 1, is a perspective view of a garage with my device installed,

Fig. 2, is a longitudinal section of a garage with my device installed,

Fig. 3, is a perspective view of the mechanism,

Fig. 4, is Fig. 2,

Fig. 5, is a section taken on lines 5 of Fig. 2, and,

Fig. 6, is a detail view of the conne ion between the operating rod and spreading links of the mechanism.

In the drawings, wherein for the purpose of illustration, 1 have shown a preferred ema section taken on lines 44 of bodiment of my invention, the numeral 5 denotes a conventional type of garage having the usual swinging doors 5, at the front of the garage and a side door 7.

A beam 8 disposed longitudinally and can trally of the garage extends througl slot 9 in the front wall 10 the garage and is attached thereto, by diverging brace bars 11. the converging ends of which are connected to the beam by a bolt 12 and the opposite ends are connected to the front wall on opposite sides of the beam by bolts 13. A pair of pulleys 14 are suspended from the inner end of the beam 8, at spaced intervals, by

U-shaped straps 15, connected to the beam 8 r by bolts 16. An operating rod 17, extends through the straps 15 and is supported by the pulleys 14. The inner end of the rod 1? is bent downwardly at right angles, as at 13, the bent end extending through alined openings in the over-lapping ends of the spreader bars 19. The outer ends of the bars 19 are pivotally connected as at 20, to brackets 21, respectively attached to each door of the garage by screws 22. The inner ends of the bars 19 are each provided with a series of openings 23, so the spreader bars may be adjusted to open the doors at any angle desired. From the foregoing it is seen that when'the operating rod is moved forward, the spreader bars cause the doors to swing outwardly to an open position and upon retraction of the red the doors swing inwardly to a closed position.

The means for operating the closing and opening of the doors consists of a drum 24,

supported by a bracket attached to a post 26, positioned aiongside of the drive-way leading to the garage, at a remote distance from the garage. The drum is journaled in the post and bracket and is provided with a handle 27 for turning the drum. Cables 28 and 29 are connected to the drum and are adapted to be wound thereon in opposite directions. The cables extend upwardly, passing through pulleys 39 attached to the upper end of the post, as at 31, and through pulleys 32, attached to the side of the beam 8, as at 33, and into the garage through an opening in the front wall. The free extremity of the cable 29 is connected to the eye 34, formed at the inner. end of the operating rod 17 and thus it is seen that when the cable 29 is wound uponthe drum 24, the operating rod is drawn forward. As more clearly shown in Fig. 4, a pair of pulleys and 36 are journaled on the shaft 37, extending through the beam 8, intermediate straps 15, the ends of the shaft being fixed in the arms 38 of the U-shaped bar '39. The pulleys are arranged one on each side of the beam, and the cable 28, extends over and under the pulley 35, havingits free end connected to the loop 40, formed in the spring washer 41, secured on the bent end of the operating rod by the nut 42. hen the cable 28 is wound upon the drum 24, it causes the spreader bars to collapse, moving the doors to a closed position.

lVhen the garage is provided with a side door, a second drum 43 is mounted on the rear wall 44 of the garage, having one end journaled in the wall and the other end ournaled in the bracket 45. Cables 46 and 47 are connected to the drum 43 and are adapted to be wound thereon in opposite directions. The cables extend upwardly and through the pulleys 48, supported by the eye 49, attached to the wall above the drum. The cable 46 has its free end attached to the eye 34 of the operating rod 17 and serves to retract the rod when the cable is wound upon the drum. The cable 47 passes over the pulley 36 and rearwardly, also being connected to the eye 34 of the operating rod. This cable moves the operating rod forwardly when wound upon the drum 43. A brace bar 50 has one end connected to the front wall of the garage on the outside, as at 51, its opposite end being connected with the beam 8, adjacent its forward end, as at 52. The outer flange 53 of each of the drums 24 and 43 are provided with a series of openings 54, adapted to aline with the opening 55 provided in the brackets supporting the drums, through which a lock, 56 may be inserted, for locking the doors in a closed or open position.

In use, a garage provided with my equipment, will enable the driver of an automobile, when he desires to enter the garage, to open the doors without having to get out of the automobile. The drum 24 is positioned so as to be easily accessible to the reach of the driver from the seat of the automobile and upon winding the cable 29 on the drum, the operating rod 17 is pulled forward, which actuates the spreader bars 19, to swing the doors of the garage outwardly to open position. After entering the garage, the driver can leave through the side door 7 and the doors of the garage can be closed by winding the cable 46 on the drum 43 at the rear of the garage. The doors may be opened and closed through operating either of the drums 24 and 43, which may be positioned at any convenient place.

It is to be understood that the form of my invention herewith shown. and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1 claim:

1. The combination with a structure having swinging doors, of a beam disposed centrally and longitudinally of said structure,

spaced pulleys suspended beneath said beam, a longitudinal movable rod loosely supported by said pulleys having its forward end bent downwardly at right angles, and movable to a point beyond the front wall of the structure, spreader bars pivotally connected with said doors, said bars having their free ends disposed in overlapping relation and pro- -vided with a series of openings adapted to register, to receive the bent end of said rod and means operable ata remote distance for moving said rod forward and backward.

The combination with a structure having swinging doors, of a beam disposed centrally and longitudinally of said structure, p-s depending from said beam at intervals, pulleys journaled in said 7 a longitudinal movable rod mat ending til h said straps and adapted to ride on said pulleys, said rod having its forward end downwardly at right angles, and movable to a point beyond the front wall of the structure, spreader bars pivot-ally connected with said doors, having their free ends disposed in overlapping relation, said ends hava series of spaced openings adapted to I :ter to receive the bent end of said rod, and means operable at a remote distance for moving said rod forward and backward.

3. The combination with a structure having swinging doors, of a beam disposed centrally and longitudinally of said structure, said beam extending beyond the front wall of the structure, spaced pulleys suspended beneath said beam in longitudinal alinement, a rod loosely supported by said pulleys and movable longitudinally of said beam and beyond the front wall of the structure, spreader bars pivotally connected to said doors having their free ends adjustably connected to the forward end of said rod, cables connected to the forward and rear ends of said rod, a pulley block at the outer end of said beam, through which said cables are trained and means for pulling said cables to move said rod forward and backward.

In testimony whereof I affix my signature.

JOHN BURCH.
