CONCEALED HINGE.

T9 all whom z5 mag/- camera Be it known that E, EL; N.Bnnnw1N, Jr.,

a citizen of the United States, residing at Stratford, county of Fairfield., State of Con- 5' nect-icut, have invented an Improvement in Concealed; Hinges, of which the fol-lowing is a specification.

This invention has for its object to` provide an inexpensive but very strong and rigid concealed hinge adapted for general use and especially adapted for use as an automobile or coach hinge, so-called, the

hinge'being wholly concealed in the closed position, being finish with the surface of the jamb in the open position and being so const-ructed as to positively retain the door out of contact with an automobile or coach body .when in thel open position. u

With these and other objects in view I have devised the novel concealed hinge which I vwill now describe, referring to the accompanying drawing forming part of this specification and using reference characters to indica-te the several parts.

Figure l is a horizontal section of a door and jamb, my novel hinge appearingin plan, thedoor being shown in full lines in the closed position and in dotted lines in a partly open position; Fig. 2 a similar View, `the door being in the fully open position and the hinge members in section on the line 2-2'in Fig. 3, looking in the direction of the arrows; Fig. 3 a view of the tace of the jamb1 and the inner face of the door .showing the hingein the fully. open position; F igsl. 4 and wperspectives of the hinge p members detached, and Fig. 6 isa view simi lar to Fig; 2, showing a slight modification in the hinge members` to permit the door to be swung past an angle of 90 degrees in the open position. I f

10 denotes the door member of the hinge as a whole, l5 the jamb member, 2 0 a door and 2l a jamb. The jamb member compri-ses a stop plate 22 which for convenience I will describe as lying in the vertical plane, attaching flanges 23 which lie in aI vertical plane at rightangles to the plane ot' the lstop plate, and side plates 2-1 whichlie in D the horizontal plane and connect the attaching anges to the stop plate. The door member comprises an attaching plate 25 and an angle plate comprising arms 26 and 27, arm 26 xtending ata right angle from the plate and duter arm 27 extending at a riglit tangle to arm 26 and par- Specication of Letters Patent. Application filed August 12, 1212. Serial No. 714,551.

alilel with the attaching plate.. The inner ,ends of stop plate 22 and of arm 27 of the angle plate are provided with corresponding hinge eyes 28 through which a pin 29 passes, in the usual manner.

Iny attaching my novel hinge in place the jamb member is let into an opening in the face 0fthe jamb and attaching flanges. 23 are also let into the face of the jamb, so as to Alie Hush therewith. Attaching plate 25 of the door member is likewise let into the edge of the door so as to lie iiush therewith.

The operation will be readily understood from the drawing. In the closed position the recess in the jamb receives the whole et' the door member with' the exception of the attaching plate, the arms of the angle plate swinging freely between side plates 24. The closed position vvof the members will be readily understood from Fig. l. It will be noted furthermore from Fig. l that owing to the arc of movement of the angle plate, the recess in the jamb only requires to be made just large eno-ugh to contain the angle plate in the closed position, as in the opening movement arm 27 swings away from the wall of the recess (see dtted position in Fig. l). lVhen the door is swung to the fully open position, arm 27 ot the angle plate Ywill lie flatl against thesuriace of stop plate 22, as clearly shown in Fig. 2. This engagement of plate 27 with the stop plate limits the opening movement of the door and renders it impossible for the edge of the door to strike the highly iinished surface'of an automobile or coach body.

Ordinarily it is preferred that the door swing to an angle o1 about 90 degrees to the plane of the body. lf preferred, however, 'by bending arm 26 to a more or less acute angle to arm 27 instead of to a -right angle thereto, and away the edge of stop vplate 22, the 4door may be swung past an angle of 90 degrees, as clearly shown in Fig. 6. i

Having thus vdescribed my.invention I claim: l

l. A concealed hinge formed from sheet metal and consisting of av jamb member comprising a stop plate in the vertical plane, attaching flanges in the vertical plane and at right angles to the stop plate and side plates in the horizontal plane which connect. the attaching tlangesto the stop plate, and a door member comprising an attaching plate and an angle plate one arm llfi of which is connected to the attaching plate, the other arm extending at a right angle and parallel with the attaching plate, said stop plate and second mentioned arm being provided with hinge eyes. y

2. A concealed hinge formed from sheet metal and consisting of a jamb member comprising a stop plate and side plates at an.

angle thereto'said stop plate being provided with hinge eyes and said side plates With attaching langes, and a door member comattaching plate andan angle In testimony whereof I affix my signature in presence of two Witnesses.
