My present invention hasreference toa door operating device.

An obj ectvof the inventionilis the provision of a simple, cheaply. constructed and easily i applied means whereby the double doors of, garages or the like maybe simultaneously swung! to open and'y closedpo'sition in an. easy and expeditious manner. f

A further object is the provision -of a Eis means for this purpose whereby the doors v will be automatically--latched1in either their open or closed positions, the latching means being such as to resist strain thereagainsty so that the liability ofthe doorsfblowingor accidentally swinging to-feither closedrorv open positions will be Ventirely and effec#V tively prevented.- v f Q The invention will Vbe fully and comprehensively understood from a consideration. so lof the following detailed?descriptionzvvhen read in connection with, the ,accompany ing.. drawings which form part of the'applica-'Y tion, with the understanding;however,that4 the improvement is capable of extended` aplplication and'is notconfined tothe exact showing of the drawings construction described and, thereforegsuch changes andY modilicationsmay be made therefrom as `do notgafectthefspirit of the soiinvention nor exceed ythe scope thereof as expressed in the` appended ,'claimsl I In the drawings; n f Figure 1` is a `fragmentarynview of the interior vof a garage, looking toward the :doors and illustrating the applicationof the' improvement.,

i yFigure 7 iis adema eievaaon. ofen@ fg Y the doors to illustrate the. handle or operating lever thereon. 1 n or o 'i On the ceiling of a garage or the like, 1 inward of but` approximately in a line 55m., with the meeting edges( of the hinged doors 2 and 3, I .secure a bracket 4that hasav depending portion which affords a pivot for For distinction one.of` the arms of the bellcrank lever is designated mp,

by the character 5 and the second arm by v the character 6.7- w

The arm 6 has pivotally secured to its outer enda rod 7, vand this rod in 'turn'is pivotally connected to a bracket 8 'on the. inner face of the door 3.

Fixed to the top of the frame for y vdoors 2 and, in a position? to be contacted by the rod 7 .when the doors are in open position, andlikewisein a position to be 7ocontacted by the innerfacey of the door 3,

when the doors are in closed position therev is astop member v9. Y;

yPivotally secured to the upperpend of the arm 5 of the bell crank lever there isa barl 10. This barl normally rests on theupper'. edge of -a substantially U-shaped-memben` which I will -term a track or rail. Theangle upstan'ding ends of the rail `11 vare 0th set and fiat and are fixed to the topy ofthe, door frame. The upper edge ofthe frail, at points adjacent to the angle ends thereof.` is;- provided with notchesf12 and 13, respectively,l and the side walls of these notches are inclined in the same direction.`

at points if the ends of the said bar. areinotchedas-at- 14, and 15, respectively, andthe end walls andthe saidy angle walls are arranged" at Van opposite inclination with respect to the angle y side Walls provided by 12 and 13.

On the inner face ofthe door 2, adjacent to the top thereof I fix a substantially U- shaped bracket 16. The bracket is vertically' o arranged,fand `its outstanding angle ends are indicated ,o for distinction f by the *nu-1 the notches or grooves VVsuitable openings in the angle ends 17 and 18ct the bracket a pivot bolt 19 which is engaged by a suitable nut, and this pivot 19 passes through a pivot opening in the outer or free end of the bar 1 The bolt 19 also passes through a suitable opening in the offset end 20 of an angularly disposed downwardly directed arm 21, the end 21 underlying the end of the bar 10'engaged by the pivot bolt 19.A Y

The lower end of the" arm 21`is flattened' and has passed therethrough a pivot-such as-- a bolt 22 that also passes through an arcuate slot 23 in the door 2. Thezbolt is `secured to the operating handle or lever 2,4 which is arranged on the outer face 'of the door 2, one

end 'of the said lever beingfpivoted tothe door 2, as at 25, and the seconder outer and offset end of thelever being received in but vertically slidable throughan angle Abracket inthe nature of a :keeper 26 which is securely fixedfonfth'e 'doorjBL The keeper and the outer end of the' lever 24fhave openings designed to register when the Y'lever is swung horizontally or into 'the keeper, and these' openings are designed to receive there through the hasp of a pad-,lock 27.

' the rail 11. As the-angle walls The arms of Vthe bell crank lever, the length' of the'rod 7 and that of the bar 10 are such as 'to positively insure the notched portion v15 of the bar 10 being received in the groove or notch 13 of the rail V11v when the door 3` is brought againstthefstep member 9. t is,lof course,l to be understood that the opening 1n thebar 10 through which the pivot vbolt 19 passes is somewhatenlarged to insure the free downward swingingA of the said bar 10. Then the doors are closed the lever 24 maybe locked in the keeper 26. When the doors'are to be opened' the lever 24 i is swung upwardly, causing'the lift arm 21 to .elevatey the'bar'- 10 above the ynotch in the rail 11, and anoutward' pull on the lever causes the swingingoft the bell 'crank lever push exerted'thereby von the rod 75 and bar 10 to swing'the'doors to'openfposi'- tion. When the rod 7 engages with the stop' bar 10 will register andthe 9 the notch 14 and the With'th`e notch 13 in the rail 11 and the bar '.will gravita-te into the notch or groove 13,`A

the angle walls'provided'by the notch 14, contacting Vwith the. opposite sides of the rail v*11 will'eifectively and' positively hold the doors open vuntil the lever l Y a similar, purpose;

` lever Y 24 is againswung to raise-the'notched portion 14 ofl the bar. vout ofthe notch or. groove 18 in the rail, so that the doors can now be swung y to closed position.

It is thought that the foregoing description, when read in Vconnection with the accompanying drawings will fully acquaint those skilled in the art to which the invention relates with the details of the construction, the operation thereof and-the manifest advantages of the invention over those for """Having describedtheinvention, I claim: 1. .An operating device for abutting hinged'doors,*comprising a bell crank, a rod pivoted to onearm-of the crank and to one of the doors, a barhaving notched edges pivoted to thersecond arm'of the crank and pivoted for slidable movement to 4the second door, a lrail on which the bar rests and havingspaced notches to `receive therein the notched portions ofthe 'bar whenfthe doors are opened or closedv and means for raising the bar to bring the-same out of the notches of the rail to permit. of the opening or closing ofthe doors.
