, 'Application-August ll, 1933,, Seria No. 684,729 3' g 3 claims." (creas -'62) Theinvntion relates to' doo'r operating means and particularly to devices adapted to beattached to-ordinary swinging double doors, to insure uniform closing at the predetermined closed position.

It is a specific purpose to present a construction in the door operating device that will enable the opening ofone door through agreaterar'c than the other where required, and which will be adjustable to vary this difi'erence to suit individual jobs. I

Another object is to-present-a' construction in closers which will operate the doors satisfactorily to insure proper overlap of the astragal or weather strip customarily applied tothe vertical swinging edge of one'door soas to overliethe other.

It is also an object to so: perfect the invention that a stock form of equipment may be produced which will be adjustable to the" various requirements of ordinaryuse without requiring'sp'ecial sizes or-fittings while yet retaining the advantages above recited. I 7

It is a purpose to enable the production of adevice embodying the invention at an. extremely low and durable in operation. 7

Additional objects, advantages and features .of invention reside in the construction, arrangement and combination iof parts involved in the embodiment of the invention as will appear from the .following description and accompanying drawv ing, wherein, 1

Figure 1 is a top plan viewof a door installation embodying my invention. r

Figure 2 is a side elevation of thetraveller and its mounting. I

Figure-3 is across section ing the latch. p I

Figure 4 is a detail of the connection between the links and doors.

Figure 5 is a fragmentary bottom view of the connection of the links with the traveller.

There is illustrated a garage frame In, including side members II and a door lintel 12 therebetween atone end. Doors l3-l4 are hinged on respective sides of the frame Ill, and these may be conventional 'doors hung in the conventional way. The right hand door I3 is adapted to move in advance of the other-in closing and the door, M is provided with an astragal strip IS on its outer face at the swinging vertical edge, projecting beyond the vertical edge of the door to function as a weather strip in the customary way. The doorsare shown as being of equal radius, but this is not essential. When closed they meet in abutment centrally-of the door opening in the ofthe traveller, show:

weight, eificient frame III, and in a common plane; 0n the lintel l2 and extending inwardly theregis mounted a Y horizontal rectilinear rail I6, which may be asim-u plechannel' bar as in Fig. 3'with its channelled side uppermost, secured to the lintel 'atthe middle of the latter and at right angles thereto Azsup-T of :the" rail port I! for the inner or rear end maybe provided, if desired.

jecting a distance above the railnear the ends, these platesbeing transversely bored to receive 1 the two pins 2! on 'whichresp'ective anti-friction wheels 29 revolve. These wheels are set between and spaced from theplates IQ'andare of a width to fit smoothly between the flanges of the channel bar l6. s

Centrally of the bottom plate 22 of-the traveller a downwardly projected-stud ,23 is provided; tenoned and threaded at its extremity to :receive a a nut 24 andwasher25 thereabove.

Respective door opening links 25 and 2 are pivoted at their extremities on the doors [3 and I4 respectively, as will be described, andat their inner ends on the stud 23. For this purpose, the

links are each formed" withza single aperture therethrough attheir outer ends, and over their inner endportions areformed with a multiplicity of apertures 28 all of a size to receive'the stud] 23 alternatively therein. The inner ends of the links are crossed with appropriate aperturesgZB. I

alined and with thestud engaged throughthe alinedapertures, a spring 29 being confined b,e-.:x, 1'35- tween the washer 25 and the links whereby the.

latter are heldon the stud and firmly against the platen without liability of rattling. The outer.

endof each link is secured pivotally bya bolt 30 to an outstanding horizontal arm '3! consisting of a fiat plate having a longitudinal series of aper-' other, and also, if desired one of the brackets may be nearer the axis oi the door if desired, in order that such door shall open further than the other, in case that be desired. And in such case the link connected to that door is connected nearer I the base of the arm 3| and the other link is connected at such distance from-the base of the other arm 3| as will equal the difference in the distances from the linkpivots on the doors 'in Figure 1. r

to the stud 23, when the door is closed, as dotted 'The traveller has the end of one plate H! ex tendedand bent laterally outward at right angles to form a latch strike as at 34. Mounted on" the inner side of the lintel [2' there is a spring-pressed latch bolt 35 slidable longitudinally of the lintel and held by its spring normally at the inner limit of its movemen't next therail I6.
