Application filed AOctober 24, 1921. Serial No. 509,878.V

This invention relates to improvements in for doors which should swing automatically to open position as for instancetoilet doors The objects of this invention are to provide a doork hinge ofthe gravity roller type which always returns by gravity to inner open position; which can be readily adjusted about its vertical axisto correct m1salignment of doors; andnally to provide a hinge of simple construction and yetof extreme durability. y

Other objects will appear from ,the following description and clai-mslwhen considered together with the accompanying draw- Fig. 1 shows the door post and swinging door in-elevation and the hinge members partly in section; Fig. 2 is a front elevation of thelower hinge member of Fig. 1; Fig. 3 is a plan View ofthe lower hinge member;

. vand Fig. 4 is a front elevation of the lower hinge member dwell portion.

f Referring to the present illustration, 1 1ntype, comprises the door member 3 secured*` 1n any suitable manner to the top of the door andhaving an `upwardly extending pin 4 for rotatable engagement in the socket 5 of the fixed member 6 which issecured to the door frame. Proper space is allowed between the upper hinge members to permit upward movement of the door, as will later appear. Y

The present invention relates more particularly to the lower hinge which comprises the door member 7 suitably secured tothe door, as for instance by means of the screws 8 secured throughy ears 9 on the plate portion 10. The ears 9 embrace the two sides of the door. Attached to or integral withV the plate 10 is a dependingy pin 11, and spaced ears 12 also provided upon the plate portion 10 afford bearing support for the pin 13 upon which turns the anti-friction roller 14. The plane of rotation of this roller is normal to that of the door.

The stationary part or the lower hinge comprises a member 15 secured to the door provided without` the rest or frame and/a cam member 16 mounted upon member 15. `The member 115 may'followthe type of str'uotureshown in the application@ above referred to or may be of any other` suitable form, as for instance, a pressed metal structurewith flanges 17 embracing and secured to the door frame. The tubular portion 18 of the pressed metal member has means of thescrews 22; Upon loosening theI Y screws 22 the cam member can be adjusted about itstubular supportjfor a vpurpose to r' be later explained. y Thel cam member is provided with :a spiral cam surface 23 inclined vuniformly in the zy same direction from end to end of' said Vsuri face yand extending approximately 180 around the axis, the cam shown in the drawi ling extending a little more than 180. This arrangement enables the door, to be, swung through aV full 180 and because the inclina- .tion of the cam is in one direction from end dicates the door post or frame and 2 a door to end the door, when allowed to move freely over the cam, always moves clear to they end ofthe cam surface and does not stop at any; intermediate position.` The hinge parts are so placed upon the door and door support that the final door position with the-roller atthe extremel low end ofthe cam will be the inner open position of the door when it is inside of the toilet compartment and substantially parallel to its side wall. The high part of the cam, at the left in Fig. 2, represents the position of the door in another or outer open position standing straight out into the passageway. However, the cam may extendfmore than 180, even as much as 270, in which the outer Open position of the door would be back approximately parallel with the lfront wall ofthe neighboring compartment.

' Whatever the outer open position of the` door is, the door will always return to the inner closed position when released and allowed to move Jfreely along the cam.

The cam shown in Fig. 4 is a simple cam of the kind just described with no intermediate position in which the door can be brought to rest. If desired, the cam surface at some suitable intermediate point may be provided with a dwell Aportion. 23, placed v orexample at approximately `90" from the low endrfoi4 the cam so thatsaid-dwellcoi'- i responds to `closed door position.
