Application filed January 25, 1922.

i w v 757/75, cones/n: 7 i5; th t i, .l'UmUs iLmnNsTniN, a. iii e of the United States, residing at, Jersey City, in the county of Hudson and of New Jersey, have invented certain new and useful lniprovements in Door- Closing Devices, of which the following is :1 specification.

vention relates to improvements ices, one of its objects means attached to the doom to allow the latter i no swung" open, to return to its origins]. close position without any further effort or attention.

ll; l'uithe? object: is to provide a device eel-opted replace the usual type of hinges general use at "the present time, and which use a swing-tor closing the door r it has been opened. These spring s h become ohjmlionuble on ac- ,F frequent replacements required,

i a or loss of tension. and other objects will become op- .in the 'lPSCllptZlOl'l. below in which ring briefly to the mowing, Figure is trout eievotionel 'ieW oi a door and frame as useo on ice boxes or the'like, closing: device being shown place 1);! lower hinge end.

seotionzil view taken on line it ierspeotive View 01' the roller ;-eril in;z the drawing more in detail, fol l indicates 1L relatively heavy door of on ice box which when closed, fits snugly into the outwardly tapered opening of The eonsti'uetion mentioned is nsuol, the pui'p-oso being to prevent, the air 'ithe ico box from reducing the tom- 1 1 tune, by escaping thru the crevices loi'nlcd lie-tween the door and wall. The (loo? is carried on special hinges comprising lined pivot plates 3 which are secured to the upright l mme member l. These plates have spaced ears 5 extending outwardly theireli'oin and adapted to receive hinge heirs o. Bolts 7 fixed in the ears form pivots upon whii'rh the (poor is supported, the ends secured bet-ween cars 7 extending from plates 8 permanently e l in horizontal z plates.

Yoke members l0 located centrally on the length of hinge bars 6 form guides and additional means for supporting the door and preventing the some from so. sing and thus twisti 55 the pivot plates troin the door or. frame. It door upon his, pci'n'iii; the doc iy into the door opening. Fla springs 9, se cured between door. uitoce and hinge bars 6 in the region of guide yokes 10 urge the door away from the hinge bars and into more intimate contact with the opening, thus insuring a snug fit at all times.

The self closiog-device essentially oomposcd of a channelled frame 1]., is preferably secured in on np ight position to the lower hinge bill by suitable bolts 12 by passing thru holes iii. t lits 13 out thru the side webs of the channelled frame fOlm means for supporting the device when being lifted. An angle iron 14. and anchor hmce l-l, extending zingulzirly downward, 'floim means for securing the closing oeirice to the lower door hinge. A. pair of plates 15 secured to the interior surtoco of tie frame Wehs at the lower end of the frame 16 by bolts 15, have small lugs 16 which shoulder upon ti o lower edge of the said frame. A rolls? 1? is rotu tubly mounted between plates 15 upon a suitable spindle retained in position between the 'f :zme Webs. The roller 1'? is so located us to have its periphery projectsoinowhat below the side plates 15, and engages to ride upon an inclined arcuate 4321711 track 18, formed upon a. rigid metallic block 19 secured to the floor in an approved manner so that the roller 17 will,

when the door is closed, be riding upon the shallow portof the com track 18 as indicated by niuuciul and when the door 1s being" opened, Will ride upward upon the orcuate path until the Toilet meets the stop" lug :21 which provides means for limiting the opening or" the door. Uhvioiisly,tho door when being opened will he lift-ed distance equal. to the perpendicular height of the 0am track 18. For this reason the upper ears '5 of the hinge plates are spaced sulliciently apart to permit this upward movement of the door as the some is being open,

Lil

When 0 ening the door a Common type of spring olt 22 is drawn from the keeper 9,3, and the door pulled open to the position desired. In opening, the door will follow the course of cam track 18, the latter being of such angle as to overcome any frictional resistance of the hinges and other members which might hold the door open at any position. Therefore as soon as retaining pressure 15 released, the roller will slowly begin. descending, the track, gaining momentum due to the weight of the door which is closed thereby.

I claim:

The combination with a door and its frame, of a closing device comprising a pair of hinge bars secured to the door, hinge plates secured to the frame, a pair of spaced horizontal ears extending from the frame plates, a vertical pin rigidly supported to extend between each pair of ears, the outer extremities of said bars extending beyond innate-i the door and being rotatahly supported by said pins as axes, said hinge bars being adapted to rise and fall on said pins between each pair of ears during opening and closing, of the door, a channelled frame secured in vertical position to the lower hinge bar, a roller axially mounted at the lower end of said frame between the sides thereof and extending below the lower extremities of said frame, and an areuate inclined cam track secured to the floor heneath the roller, said roller being adapted to engage the lower end of the cam track when closed and to ride upward on said track during opening of the door, the weight of the door causing said roller to descend said track when the opening force on the door has been released, to cause said door to close. y
