' HINGE File d- NWT-"29, 1939 INVENTOR. JOHN R .DoMA/v A rroe sy Patented Sept. 15,1942

T D snares T OFFICE 2 Claims.

This invention relates to hinges and more particularly to hinges for use on doors and the like.

This application is a continuation in part of my prior application for Hinges, filed July 25, 1939, Serial No. 286,382.

An object of the invention is to provide a simple, practical and inexpensive article of the character described.

Another object is to provide a hinge for doors and the like whereby the door may be swung through a full arc of 180 degrees.

A further object is to provide a hinge as described which is completely concealed in closed position.

An additional object is to provide a hinge as described having an adjustable stop.

A further object is to provide a hinge having means for holding the door open in any position.

Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawing, wherein:

Fig. 1 is an elevation view of a hinge embodying my invention as seen in position in a door and jamb;

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken along the line 33 of Fig. 1;

Fig. 4 is a View similar to Fig. 3 showing the door in open position;

Fig. 5 is a sectional view taken along the line 55 of Fig. 1;

Fig. 6 is a perspective view of one of the hinge members; and

Fig.7 is a perspective view of one of the bearing members.

Referring more particularly to the drawing, I show a door jamb I and door I I each of which is suitably recessed to receive a hinge part. A hinge bracket I2 is secured in the jamb recess as by countersunk screws according to the usual manner, and a similar bracket I3 is secured in the door recess. The brackets I2 and I3 are identical except for certain parts which are positioned on opposite sides thereof as will be manifest hereinafter. Brackets I2 and I3 have flange portions I4 provided with countersunk screw holes I for mounting screws l6 and each bracket has a U-shaped portion II, the side portions of which are provided with square apertures I8 which receive the squared end portions I9 of a bearing pin 20. Apertures I8 are nearer one A substantially U-shaped link 2| is provided with bearing bores 22 adjacent the ends thereof for mounting on bearing pins 26. U portions ii are each provided with a pair of stop lugs 23 which limit the movement of the door as may be seen in Fig. 4. Members l2 and I3 are each provided with a threaded bore 24 in which is positioned a threaded stop screw 25 which may be provided with a lock nut 26. Stop screws 25 are adapted to engage the side portion of member 2| for limiting the position of the same in the closed position of the door.

Members I2 and I3 are each provided with a plate 21 positioned between member 2| and the upper part of portion ll of the brackets. Plates 2? are each provided with a square aperture 28 to permit portions I9 to extend therethrough. Portions II are each provided with a threaded bore 29 in which is located a screw 30, the lower end of which presses against plate 21 such that the tightening of screw 36 will force plate 21 against member 2| and serve as a brake for the same.

Screws 30 are preferably provided with fiat heads 3| having a screw driver slot 32 in the top thereof, and they are preferably provided with a plurality of peripheral notches 33 by which screws may be adjusted after installation, a hole 34 being formed in each member I2 and I3 to permit a small screw driver to be inserted therethrough and engage notches 33 whereby the screws may be turned.

The operation of the invention should be clear from the foregoing description. With the door in a closed position as shown in Fig. 3, stop screws 25 engage link 2| and determine the limiting position of the linkfor this closed position of the door. When the door is opened a quarter of a turn as indicated in full in Fig. 4, bracket I3 will have been pivoted degrees carrying with it pin 26 which has been rotated with the center of bore 22 as an axis. Portions I9 of pin 20 will likewise have been rotated and the corner edge A of the door will move in along an arc indicated B which as seen will permit corner A to swing past the face C of the door jamb without interference because of the eccentric position of portions I 9. When the door is swung to the full open position, or a swing of degrees as shown by the dotted position in Fig. 4, lugs 23 which engage the inner sides of link 2| bracket members each having a U-shaped portion, a link pivotally mounted at its ends in said U portions of the brackets, one of said brackets having a friction bearing plate between one of said U portions and said link, and means to adjust the pressure of said plate against said link, said means including a screw in said U portion adjacent said plate provided with a peripherally notched head, said bracket having 10 an aperture adjacent said screw head.
