Patented ct. 27, 17931x UNITED STATES PATENT OFFICE DOOR OPERATING MEANS Application led vDecember 22, '1930. Serial No. 503,991.

This invention relates to door operating mechanism and has for its principal object the provision of means whereby double doors, such as garage doors, may be swung simul- 5 taneously to open or closed position.

Another object is the provision of means whereby the operating mechanism may be actuated from a distance.

Another object is the provision of means whereby certain mechanism is operated to trip a tension spring'which, when moved to a predetermined position, will actuate the door operating mechanism.

if] ith these and other objects in view as will appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application, in which:

Fig. 1 is a top plan view of the preferred embodiments of my invention, the same .being taken on a .plane just below the ceilingy of a garage.

F ig. 2 is a sectional view taken on the line 2-2 of Fig. 1 the ceiling and roof being shown in this view.

Fig. 3 is a similar view to Fig. l, disclosing a modified form of my invention.

Like numerals of reference designate corresponding parts throughout the different views.

3 is a guide bar reciprocally mounted in suitable guide brackets 4, which guide brackets are secured to the ceiling ofthe garage or a suitable platform 5. Secured to the top and bottom faces of the guide bar 3 are U-

brackets

6 and 7 Extending through the U- 7 and guide Vbar 3 is a bolt 8,

brackets 6 and which is headed at one end and provided with a lock-nut 9. Pivotally attached at one end to the bolt 8, between the U-bracket 7 and the guide bar 3, are connecting

rods

10 and 11. The opposite ends of the connecting rods 10 and l1 respectively, are pivotally Vsupported in

bearing brackets

12 and 14 secured to the inner face-'of the

garage doors

15 and 16,'in spaced relationship from the hingeslf and 50. 18 respectively. The connecting rods .1() :and

l1 are preferably offset intermediate their ends as at 19 and 20 so that the outer ends thereof may be conveniently attached to the

doors

15 and 16 respectively. 21 is a lever arm pivotally connected at one end to a bolt 22, extending downwardly from and secured to the ceiling or pl( tform 5. The opposite end of the lever arm 21 is forked as at 23, the free ends of the prongs 23a and 23?) of the fork 23 converging towards each other. The prongs of the fork 23 straddle the bolt 8 between the U-brackets 6 and the guide bar 3. 24 is an operating lever pivotally connected at one end to the bolt 22 and supported at its free end by the guide bracket 25, which guide bracket is sec ered to the ceiling or platform 5. 26 are spaced apertures formed through the lever arm 21. 27 is a bolt or stud extending through one of the apertures 26 and secured therein by the lock-nut 28. 29 are spaced aperturesI formed in the operating lever 24. 30 is a bolt or stud extending through one of the apertures 26 and secured therein by the lock-nut 3l. 32 is a tension spring, one end of which is connected to the bolt or stud 27 while the opposite end thereof is secured to the bolt or stud 30. The bolts 27 and 8O may be replaced in the

apertures

26 and 29 inwardly or outwardly relative to each other to diminish or increase the tension of the spring 32. 33 is a flexible member connected at one end to the free end of the operating lever 24. The flexible member 33 is trained over the pulley 34, extended out through an aperture 35, formed in the front wall of the garage, and thence extended to a predetermined location. 36 is a flexible member :attached at one end to the free end of the operating lever 24. The flexible member 36 extends through the opening 35 and to a point adjacent :the free end of the fiexible member 33. Attached to the free end of the flexible member 33 is a suitable ring or handle 37. Attached to the free end of the flexible mem ber 36 is a suitable ring or handle 38. Suitable .

pulleys

39 and 40 may be provided, over whichpthe free ends of the

flexible members

33 and 36 respectively may be trained and suspend'ed.

VReferring to F ig. l, it will be noted that the i operating lever 24 is retained in angularre-V lationship to the lever arm l21 by means of the tensionspring 32 which spring, through the mediums of the guide bracket 25, bolt.

rods

10 and 11, will retain the

doors
