Application tied Noiember is, rare. Serial at. 731,292.

vide a hinge of this type of simple con struction and eilicient in operation, which hinge may be applied to doors swinging in both directions and is adapted to automatically return the door to closed position when opened in either direction, and is further apt-ed to hold the door in fully opened position. A specific embodiment of my invention illustrating this and other advantages is described in detail in the following specification and is illustrated in the accompanying drawings forming part thereof and illustrating a preferable embodiment or themvention.

In them drawings, Figure 1 is a fragmentary view in elevation, partly in section, of the ower inner end of a swinging door showing my closer hinge applied thereto as Fig. 2 is (a horizontal sec a floor hinge. tiona'l view taken on the line 22 of Fig. 1.

Fig. 3 is a view in elevation of the stationary pivot member detached.

Referrin to the drawings by numerals, 1

indicates a our of the double swinging type. At a point below the door and adjacent its inner orig cl, a floor plate 2-is fastened to the floor or treshold of a door casing in which is rigidly mounted a pivot member 3 whose squared lower end 4: is seated in a similar recess formed in the floor plate and is preferably upset therea ainst. This pivot mema socket 5 therein and her is provided wit with an annular head 6 concentric thereto and extending upwardly therefrom, the edge or this annular head bein cut away at one aid; to form complementa arcuate cam surfaces 7 extending upwardl and in opposite directions from an interme iate andcommon low point 8. The high points of these cam surfaces terminate in the flat surfaces 9 of the head.

lower ball race within the socket 5 0 V p 1 member. Thespindle 15, of course, extends Extending up within a recess formed in the bottom of the door 1 is a bracket plate or bar 10 havin its upper end terminating in an arm 11 an having also a lower arm 12 seated against a cutout portion at the under edge of the door, and being split at its end to form a bent tongue 12'} seating within a, slot 13 formed in a bottom bar 14, which is secured to the bottom recessed edgeoi the door and to the lower arm 12 of the bracket- 10, the forward or inner end of this bar seating under and against the head 6 of the 1 pivot member.

A spindle 15 having its upper portion threaded and its upper extremity flattened as at 16, is 'seated at ,said upper end in an aperture formed in the upper arm 11 and corresponding in shape to the shape of the flattened end of the spindle so that said spindle is held by said bracket arm against rotary movement. The flattening of the upper end of the spindle forms shoulders which rest against the under face of the arm 11 or the bracket. The lowerend of the spindle seats in the socket 5 or the pivot member 3, its end resting upon and being supported by a bail race formed of two bearin washers 17 inciosing a plurality of steel ha ls 1'8.

Slidably mounted on the lower portion of the spindle 15 is a bearing sleeve 19 against which bears the lower end of a coiled spring 20 encircling the spindle and engaged at its upper end by an adjusting and tensionihg nut 21 threaded on the upper end of said spindle. A look nut 22 is also preferably provided to codperate with the adjusting nut 21. v i r The bracket bar 10 adjacent its lower end is provided with an elongated slot 23 within which slides the flattened end 25 of a stud 24- whose other end is threaded into the portion of the bearing sleeve 19, and on which stud is journaled an anti-friction roller-26.

It will Patented Mar. id, 19313..

be evident from the foregoing that the door is journaled on' the pivot member 3 by reason of the s indle 15 carried byth'c door through the racket resting upon the Y the pivot in the line oi axis oi the pivot stud, and the bearing part 19v carried thereby likewise lies in said line oi? axis. As this hearing portion is connected to the bracket through the connection of the stud 2d therewith, it will be obvious that as the door is swung, the bearing sleeve 19 and its anti-friction roller contact 26 will swing with the door. 'ihis roller contact is-so positioned that when the door is closed, it will rest upon the intermediate low part 8" between the complemental cam surfaces? of! the, pivot head; 'lhese cam surfaces each extend in an arc, with the pivot member has the center, the combined arcs of the complemental cam surfaces being preferably slightly less than a semi-circle. When the door is swung in either direction from closed position, it will,

' tain the door in fully opened position. llt

ill

the door is not swung entirely open, or .in an arc of less than ninety degrees, the antifriction roller will not pass over the high point of the cam surface, and-releasing said door, will, through the power of the compressed spring 20, move said roller downwardly against the inclined cam surface and return the door to closed position I find that in practice the pressure of the compressed coiled spring 20 serves to trictionally hold the anti-frictionroller 26 a ainst the top flat surface of the annular hea so that the door is held in opened position when, swung in either direction, but it is obvious that this flat edge at points at substantially ninety degrees to the intermediate low portion 8 of the cams, may be provided with a slight concavity into which the antidriction roller will be pressed by the spring to lock the door against closing movement.

A door to which my closer hinge is applied is, oi course, provided with a'stud at its opposite end seated within a socket formed in the door casing. It is obvious that in mounting such a door provided with my closer hinge, the entire hinge including the door plate may be first secured to the door and then the door moved to bring its upper stud within the socket in the casing of the door. The lower end of the door can 7 then be positioned to bring its floor plate in the line of axis" of the upper stud, and said intern What I claim, therefore, and desireto secure by Letters Patent is:

1. In a device of the character described, a stationar pivot member having a socket formed t erein and having a concentric an-' nular head extending. outwardly from said socket and provided with complemental cam surfaces thereon extending in opposite directions from an intermediate low point, a door, a spindle connected to said door extending in the line of axis of said pivot member and having its end journaled in. the socket there. of, anti-friction thrust bearings within said socket tor said spindle end, a bearing member guided on and movable longitudinally of said spindle and having a contact member positioned to engage said annular head and to seat in the intermediate low point of said cam surfaces when the door is in closed position, and spring means cotiperating with said bearing member to hold it in engagement with said cam surfaces.

, 2. In a device of the character described, a stationary pivot member having a socketformed therein and having a concentric an-v nular head provided with complemental cam surfaces thereon extending in opposite directions from an intermediate low point, a door, a spindle connected to said door extending in the line of axis of said pivot member and journaled in the socket thereof,

anti-friction thrust bearings within said socket for said spindle end, a bearing member movable longitudinally of said spindle and having, an anti-friction contact member positioned to engage said annular head and to seat in the intermediate low pointof said cam surfaces thereof when the door is in closed position, and spring means for moving saic bearing part to force its contact member into engagement with said cam surfaces.

3. ln a device of the character described, a stationary pivot. member having a socket formed therein and having a concentric annular head extending outwardly therefrom and provided with 'complemental cam surfaces extending in opposite directions from an intermediate low oint and terminating in flat surfaces at then high points, a door, a s indie connected to said door extendin in t e line of axis of said pivot member an having its end journaled in the socket thereof, anti-friction thrust bearings within 1,ose,171

said socket for said spindle end, a bearing member guided on and movable longitudinally of said spindle and having a part positioned to engage said annularhead and to seat in the intermediate low point of said cam surfaces when the door is in closed position, and a closer spring cooperating with said bearing member to move itto engage with said cam surfaces.
