Patented Oct. 20, 1931 STEPHEN H. GAY, or DALLAS, TEXAS CLOSURE OPERATOR Application filed November 14, 1930. Serial No. 495,759.

This invention relates to an operating device for closures, and it has more particular reference to a garage door assembly and vehicle actuated door opening means.

} More specifically related, the inventlve conception comprehends an arrangement which embodies a swingably mounted horizontally disposed barrier plate which is arranged in advance of the horizontally swing- :0 ing garage doors and which has operating connection with the doors for drawing or pulling the doors to open position, manually manipulated release means being provided for permitting'the doors to be returned to I closed position through the medium of spring means.

The particular details and their relative arrangement thereof will become more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is a rear elevational view of a garage equipped with the invention as developed in accordance with the present conception.

Figure 2 is a plan or horizontal fragmentary sectional view with one of the doors swung to open position- Figure 3 is a vertical sectional view taken approximately on the plane of the line 3-3 of Figure 1.

Figure 4 is a detail view of a rocker lever.

Figures 5' and 6 are details of the trip latch.

Figure 7 is a detail view approximately .on the plane of theline of Figure 2.

Figure 8 is a detail view of the pulleyequipped guide bracket.

Referring to the drawings in Figure 1, the garage or building is generally designated by the numeral 9. "The foundation or floor is indicated at 10. The garage doors are represented by the numerals 11 and 12. The hinges are indicated generally by the numerals 13. These hingesare such as to permit the doors to swing open in a horizontal plane in the usual way and each hinge includes a coiled spring, the tendency of which is to swing the doors to closed position automati- '50 call Mechanical means is therefore necessary to open these doors against the tension or action of the springs in the hinges.

Referring now to Figures 1, 2 and 3, it will be observed that the numeral 14 designates generally a barrier which is hingedly -65 mounted at 15 on the foundation or floor. This is swingable in a direction toward the doors as seen in dotted linesin Figure 1. At its ends, the plate is provided with extensions 16 having knuckles 17 provided with pin 18. There is a horizontal operating rod 19 pivotally connected as at 20 with the pin 18. The rod extends in a horizontal plane and in parallelism to the floor through a guide hole formed in the door frame21. This is shown in Figure 7.

' In this hole is an anti-friction pulley22 to facilitate reciprocatory motion of the rod. At its inner end the rod terminates in an eye 23 with which a pull cable or cord 24 is con 7 nected. This cord extends downwardly and out through a guide hole 25 in the frame, where it is trained over a pullev 26. on an especially designed guide bracket 27. The

guide bracket is anchored underneath the rod- 19 as shown in Figure 2. I

The opposite end of the cable is attached as at 28 to the lower intermediate portion of the adjacent door. As before stated, this arrangement is duplicated for each door. '80 The result is that when a vehicle comesalong the runway and runs against the barrier 14, it will push the barrier down to the dotted line position shown in Figure 3. This will exert a rearward thrust and sliding action upon the rod 19. The rod will in turn exert a pull on the cable 24 thus tightening the cables and swinging the doors outwardly to open position against the tension of the spring hinges 13.

As the barrier plate 14 is swung down, it is caught in this position by a pivotally mounted latch 29 as shown in Figure 3. There is arocker provided at 30 and this includes an upstanding lever 31 and a hori-' zontal rocker shaft 32 mounted for rotation in suitable bearings. On the inner end of the rocker shaft is a rocker arm 33 which is in turn connected with a link 34:. The link extends inwardly into the recess or compartment 35 where it is pivotally connected with the lower end portion of the latch 29.

It follows that by grasping the lever 31 and moving it in the proper direction, the

latch 29 will be disengaged from the plate 14. Through the medium of the spring hinges, the door will be automatically swung to closed position.

Briefly, the operation of the device is as follows: The vehicle comes along the runway or foundation and the front wheels come into contact with the abutment or ban rier plate 14. The vehicle continues to move toward the doors and in so doing, swings the plate inwardly and downwardly to the dotted line position represented in Figure 3.

As the plate is swung down, it is engaged and held down by the latch 29. This does not require the driver to get out of the machine, for as the plate 14 swings down, it operates the pull cables through the medium of the operating rod 19. As before stated. this swings the doors to open position and allows the vehicle to enter the garage.

In order to close the doors however, it is necessary for the driver of the car to catch hold of the lever 31 and to move it to a position to release the latch 29 and to allow the springs of the hinges 13 to return the operating means to normal set position. In coming out of the garage, the doors may be swung open by hand so that the plate 14 may be held down to allow free exit to be made.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as nnnecessary. Minor changes in shape, size. and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.
